TECHNICAL FIELD The present invention relates to a joint resonator or a joint-receiving device whose shape of the tips for pressing a joining object on the joining resonator and the tips for pressing the joint object to the joining receiving device is at least so inventively formed that a joining of metal foils by means of ultrasonic vibrations or sound vibrations is possible without protecting the metal foils by protective elements from the tips.
Background Art Referring to Figs. 4 and 5, the metal joining disclosed in Non-Patent Document 1 will be explained. In the case of the metal joining shown in FIG. 4, a joining object 52 is transduced ultrasonically in the transverse direction by a resonator 53, while the joining object 52 consisting of multi-layered metal elements 51 is pressurized by a resonator 53 and a die 54 the boundary surfaces of the multi-layered metal elements 51 with each other on a friction, wherein the heating due to the frictional heat, the movement of the metal atoms is more active, so it comes to the migration of metal atoms by diffusion, the metal atoms are connected by the resulting between the metal atoms mutual attraction forces and the multi-layered metal elements 51 are joined together. As shown in FIG. 5, the tips 55 for pressing the metal members 51 on the resonator 53 and the tips 56 for pressing the metal members 51 on the die 54 are gradually tapered in the protruding direction from the side of the resonator 53 or the die 54, formed pyramidal or truncated pyramidal projections which engage the joining object 52 shown in Fig. 4.
Recently there has been, for example, For lithium-ion batteries, the tendency for a lower thickness of the individual metal foils and a higher number of sheets of metal foils to be joined. With such a small thickness of the metal foils and a higher number of sheets of metal foils to be joined, however, joining occurs when metal foils are damaged when the tips 55 and 56 formed from pyramidal or truncated pyramidal projections pierce the metal foil and abut against the cut edges of the metal foils the tips 55 and 56 adjoin surfaces to form projecting corners.
In order to avoid damage to the metal foils by the tips 55 and 56 formed of pyramidal or truncated pyramidal projections, the application of the invention disclosed in paragraphs [0027] to [0030] and FIG. 5 of patent document 1 is for joining metal foils possible by means of ultrasonic vibrations. Referring to Fig. 6, the joining of a plurality of metal foils 61 by ultrasonic vibration using the invention disclosed in paragraphs [0027] to [0030] and Fig. 5 of the Patent Document 1 becomes possible for joining metal foils by means of ultrasonic vibrations.
Referring to Fig. 6, the joining of a plurality of metal foils 61 by ultrasonic vibration using the invention disclosed in paragraphs [0027] to [0030] and Fig. 5 of the Patent Document 1 will be explained. As shown in Fig. 6, the multi-layered metal foils 61 are clamped by metal plate-made protective members 62 and 63 from above and below, the protective members 62 and 63 from the tips 55 of the resonator 53 and the tips 56 of the die 54 from above and below clamped, the metal foils 61 and the protective elements 62 and 63 from the resonator 53 is pressurized and vibrated ultrasonically, and the metal foils 61 and the protective elements 62 and 63 interlocked by the ultrasonic vibrations without the tips 55 and 56, the protective elements 62 and 63 and the metal foils 61 are damaged.
However, since in the metal joining shown in FIG. 6, an operation for protecting the multi-layered metal foils 61 by the protective members 62 and 63 is added, an application is not possible without further preparation.

EMBODIMENTS OF THE INVENTION With reference to FIG. 1, a joining device 31 using ultrasonic vibrations or sound vibrations is explained according to an embodiment of the invention. A resonator 1 used in the joining device 31 shown in FIG. 1 forms a joining resonator 1 for joining a joining object 41 by means of ultrasonic vibrations or sound vibrations, so that it is expressed as a resonator 1 in this specification. The resonator 1 is for
Purpose of joining e.g. made of an aluminum alloy, a titanium alloy or an iron alloy, and has a resonator main body 2, holder 3 and a joining tool 4. A workpiece-side surface 5 of the joining tool 4 faces the joining object 41 during joining and forms a flat surface of the transverse direction orthogonal to the longitudinal center line of the joining tool 4. At the workpiece-side surface 5 tips 6 are provided. At a workpiece-side surface 5, there may be one or more tips 6.
The tips 6 are portions of the resonator 1 positioned on the side of the joining object 41, and also portions pressed against the joining object 41 in joining, with a plurality of hemispherical or half-round-shaped projections 7 and 8 are formed without sharp edges on the outer surface in such a shape that they are two-level superimposed in the longitudinal direction than the direction in which they the resonator 1 and the receiving device 40, and also the projection 8 on the side of the joining object 41 smaller is as the projection 7 on the side of the resonator 1. Since the projection 8 on the side of the joining object 41 has a slightly smaller shape than the projection 7 on the side of the joining resonator 1, in this description, the projection 7 on the side of the joining resonator 1 as a large projection 7 and the projection 8 on the side of the joining object as a small projection 8 expressed t. Further damage, characterized in that the small projection 8 is formed protruding from the large projection 7 to the side of the joining object 41 so that when joining the small projection 8 in front of the large projection 7 comes into contact with the joint object 31, the tips 6 when joining not Metal foils, even if as a joint object 41 multi-layered metal foils are used, which eliminates a step to protect the multi-layered metal foils by protective elements. The number of tips 6 from the large tips 7 and the small tips 8 may be one or a plurality. In the event that there are a plurality of tips 6, the respective tips 6 may be of different size or of the same size.
The mass of the supernatant from the outside of the resonator main body 2 of the joining tool 4 to the underside are dimensioned such that the workpiece-side surface 5 and the projections 6 form the points of the largest oscillation amplitude with the largest oscillation amplitude in the direction indicated by the arrow 9 transverse direction. Incidentally, the length of the resonance main body 2 from one end to the other end in the transverse direction should be at least half the wavelength of the resonance frequency of the ultrasonic vibrations transmitted by the oscillator 38, in the example, a length of one wavelength. The resonator main body 2 may be round-shaped or have a rectangular bar shape. The points having the largest vibration amplitude are located at both ends in the longitudinal direction as well as in the central portion of the resonator main body 2.
At the point of maximum vibration amplitude in the central portion in the longitudinal direction of the resonator main body 2, the joining tool 4 is provided projecting from the outside of the resonator main body 2 toward the bottom. Is the joining tool 4 from the outside of the resonator main body 2 on the bottom only to a slight extent, the joining tool 4 can also be provided on the upper side, front side or rear side projecting from at least one side on the outside of the resonator main body 2.
At the points of the smallest vibration amplitude between the longitudinally central portion and the two ends of the resonator main body 2, the holders 3 are provided projecting from the outside of the resonator main body 2 to the outside. The point with the smallest oscillation amplitude is also called a node. The state in which the holders 3 protrude from the outside of the resonator main body 2 toward the outside becomes clear with reference to paragraph [0013] and FIG. 2 of the patent of JP Patent No. 4564548.
If the resonator main body 2 is a round bar shape, the holders 3 can also surround the resonator main body 2 in the circumferential direction. The state in which the holders 3 enclose the resonator main body 2 in the circumferential direction will become apparent with reference to FIG. 5 or FIG. 18 of the patent of JP Patent No. 2911394.
The resonator main body 2 can also be constructed such that the central portion with the joining tool 4 and the two ends with the holders 3 are coaxially connected by connecting elements such as headless screws or threaded rods, whereby the structure is complicated.
The central portion of the resonator main body 2 with the joining tool 4 is called "Phone" and the two ends of the resonator main body 2 with the holders 3 are referred to as "booster".
The joining tool 4 may be integrated by its structure both in the resonator main body 2, as well as being connected as a separate component of the resonator main body 2 by connecting elements such as headless screws or threaded rods with the resonator main body 2. If the joining tool 4 is constructed so as to be connected to the resonator main body 2, the joining tool 4 may be fixed to the resonator main body 2 instead of connecting members such as headless screws or threaded rods by means of binders such as brazing material and so on. As forms for the entire joining tool 4 round rod shapes or rectangular rod shapes can be used.
The joining device 31 shown in Fig. 1, in the upper portion of a device frame 32, a pressure mechanism 33, wherein on a dispensing element 34 of the pressure mechanism 33, a holder 35 is provided. The holder 35 has on both sides in the transverse direction, ie right and left of a forward and rearward and downwardly continuous cavity 36 holding parts 37. On the holder 35 of the joining resonator 1 is mounted for joining the Fügeob jects 41 by means of ultrasonic vibrations or sound vibrations, wherein the holder 35, the longitudinal direction of the resonator 1 is aligned in the direction shown by the arrow 9 transverse direction, and not to the holder 35 touch, the other parts of the resonator 1 except the holders 3 in the cavity 36 and the outside of the holder 35 are arranged, and the holder 3 are supported by the holding parts 37. As a result, the resonator 1, which has an oscillator 38 at one end, is mounted supported by the retractable and retractable holder 35 in a horizontal position on both sides. Hereinafter, the joining resonator 1 is referred to as a resonator 1.
An output end portion 39 of the oscillator 38 is coaxially connected by a connecting member such as a headless screw or a threaded rod to one end of the resonator 1 in the transverse direction, and the resonator 1 resonates with the sound vibrations or ultrasonic vibrations transmitted from the oscillator 38. In the lower portion of the device frame 32, a receiving device 40 is provided as a die in a position just below the joining tool 4. The receiving device 40 used in the joining device 31 illustrated in FIG. 1 forms a joining receiving device 40 for joining a joining object 41 by means of ultrasonic oscillations or sound vibrations, so that the joining receiving device 40 is expressed as a receiving device 40 in this description. As a resonator 1 is one of the double-supported type with holders 3 shown on both sides in the transverse direction to the joining tool 4, but also possible is a one-sided supported type with a holder on one side in the transverse direction to the joining tool 4. As the resonator 1, however Double-supported types when loading the joining object with the joining tool 4 fewer deviations in the load on the joint object on than supported on one-sided types.
For joining a joining object 41 by means of the joining device 31 shown in FIG. 1, in a state in which a cavity into which the joining object 41 can be inserted is formed between the tips 6 of the resonator 1 and the receiving device 40, and the tips 6 of the resonator 1 and the pickup 40 are vertically aligned with each other, the joining object 41 is set on the pickup 40. Next, the pressure mechanism 33 is driven, and due to the lowering of the output member 34, the joining object 41 is pinched and compressed by the tips 6 of the resonator 1 and the pickup 40 from above and below, the resonator 1 enters with the sound vibrations transmitted from the oscillator 38 Ultrasonic vibrations in resonance, the tips 6 of the resonator 1 vibrate in the transverse direction shown by the arrow 9 and the joining surfaces of the joining object 41 absorb the pressure and the vibration energy from the tips 6 and are joined together. Subsequently, the printing mechanism 33 is driven and due to the lifting of the output member 34, the tips 6 are released from the joining object 41 and the joining object 41 remains on the receiving device 40. Then the joining object 41 is removed from the receiving device 40 and the first joining operation of the joining object 41 is completed ,
As shown in Fig. 1, the tips 6 of the large projections 7, which have no sharp edges on the outside, and the small projections 8, which are formed in a smaller shape than the large projections 7, of the protrude large projections to the side of the joining object 41 and on the outside have no sharp edges formed in two stages, so that in the step of joining the joining object 41, first the energy of the sound vibrations or ultrasonic vibrations is concentrated on the small projections as a first stage and as a trigger a shift acts and the large projections 7 as the next second stage can smoothly insert the portion in the vicinity of the small projections 8. This allows a joining with a lower energy of the sound vibrations or ultrasonic vibrations, d. H. a smaller amplitude of vibration, a lower load and done in a shorter time. Further, by concentrating the energy of the sound vibrations or the ultrasonic vibrations on the small protrusions 8, the joining strength is improved and the yield of the joining becomes better. Of these effects, it is particularly important that the sonic or ultrasonic vibration used for joining with the joining device 31 shown in Fig. 1 is joined with a vertical vibration set at 15 kHz as the frequency from the range of 10 kHz to 50 kHz has been.
It could be demonstrated that when joining with a set to 15 kHz as frequency from the range of 10 kHz to 50 kHz vertical vibration as sound or ultrasonic vibration, which is used for joining with the joining device shown in Fig. 1 , as joining object 41 by means of the joining device 31, for example Resin compounds having layers of a plurality of thermoplastic resin, metal compounds having layers of a plurality of similar or different metal elements, compounds of different materials with layers of a plurality of similar or different metal elements with unilaterally above or below or even applied on both sides Resin cushions, compounds of different materials with layers of metal elements and ceramic elements, compounds of different materials with layers of metal elements and ceramic elements with unilaterally above or below or also applied on both sides Harzkissen, compounds of different materials with layers of metal elements and synthetic resin elements, compounds different materials with layers of metal elements and synthetic resin elements with one side above or below or applied on both sides H / H Cushion can be used.
Even if it is the joint object to multi-layered metal foils, in particular made of aluminum or copper, the tips 6 damage the metal foils when joining, since the tips 6 of the resonator 1 for pressing the metal foils in two stages from the large projections 7 and the small projections 8 are formed. When attempting to add as a metal foil 60 sheets of laminated copper foils of a thickness of 10 μm by means of a joining device 31 according to FIG. 1 with vertical oscillations fixed at 15 kHz, or when attempting to stack 60 sheets
To add aluminum foils of a thickness of 20 microns by means of the joining device 31 shown in FIG. 1 with fixed to 15 kHz vertical vibrations, no damage to the copper foils and the aluminum foils has been shown to occur.
Between the central portion of the resonator 1 with the joining tool 4 and its two ends with the holders 3, between the resonator 1 and the joining tool 4 or between the resonator 1 and the Ausgangsendabschnitt 39 of the oscillator 38 may also not shown here intermediate booster be coaxially and integrated by means of a connecting element of a headless screw or a threaded rod in the transverse direction. The intermediate booster serves to adjust the amplitude of the resonator 1. The amplitude of the resonator 1 can be both increased and decreased by the order of magnitude (shape) of the booster is changed. If no intermediate booster is used, the amplitude of the resonator 1 is equal to the amplitude of the oscillator 38, d. H. easy. However, it also happens that a simple booster is used.
As the joining device 31, it is also possible to use a joining device disclosed in the patent document of JP Patent No. 2911395, in which the resonator is arranged vertically.
In the vicinity of the two-stage formed from the large projection 7 and the small projection 8 tip 6 of the workpiece-side surface 5 shown in Fig. 5, a peripheral projection, the illustration has been omitted, are provided. The dimension of the protrusion of the peripheral protrusion omitted from the workpiece side surface 5 is less than the protrusion protrusion of the tip 6 from the workpiece side surface 5, so that when joining, the peripheral protrusion whose appearance was omitted without the joining object 41 to damage, be pushed in and be joined.
Further, in Fig. 1, the case has been shown that the tip 6 of the resonator 1 is formed such that the projections 7 and 8 in the resonator 1 and the receiving device 40 facing direction 2-stage superimposed, but it is also a structure is applicable in which a plurality of projections in the resonator 1 and the receiving device 40 facing direction at least three levels superimposed. In a construction where e.g. a plurality of protrusions in the direction facing the resonator 1 and the pickup 40 are in three-stage superposition, the protrusion closest to the joining object 41 side has the smallest shape, the protrusion closest to the resonator 1 side has the largest shape, and the protrusion between the protrusion closest to the joining object 41 side and the protrusion nearest to the resonator 1 side has a larger shape than the protrusion having the smallest shape closest to the joining object side 41 and a smaller shape than the protrusion having the largest shape closest to the resonator 1 side. In this way, in a structure in which a plurality of protrusions in the direction facing the resonator 1 and the receiver 40 become three or more superimposed as three stages, the respective shape of the plurality of projections from the side of the resonator 1 to the side of the joining object s 41 smaller. Further, for a workpiece-side surface 5 of the resonator 1, a plurality of tips 6 in which a plurality of projections are 2-step, 3-step, or multi-step superimposed may be provided.
Further, to the tips of the pickup device 40 on the side of the joining object 41, a structure is also applicable, in which a plurality of the protrusions 7 and 8 shown in Fig. 1 in the resonator 1 and the recording device 40 facing direction in two stages superimposed. Even if now, e.g. the tip 6 provided on the workpiece-side surface of the receiving device 40 consists of the projections 7 and 8, which are in two-stage superimposition in the direction facing the resonator 1 and the receiving device 40, the projection 8 on the side of the joining object 41 has a smaller shape than FIG the projection 7 on the side of the resonator 1. Further, at the tip of the recording device on the side of the joining object 41 also the structure can be applied, that a plurality of projections in the resonator 1 and the receiving device 40 facing direction three or more levels superimposed , In a construction where e.g. a plurality of protrusions in the direction facing the resonator 1 and the pickup 40 are in three-stage superimposition, the protrusion closest to the joining object 41 side has the smallest shape, the protrusion closest to the receiving device 40 side has the largest shape, and the protrusion between the protrusion closest to the joining object 41 side and the protrusion closest to the receiving device 40 side has a larger shape than the protrusion having the smallest shape closest to the joining object side In this way, in a structure of the tip of the pickup device 40, in which a plurality of protrusions in the resonator 1 and the pickup device 40 facing Direction in three or more than three stages superimposed, the respective form of the plurality of V Or jump from the side of the recording device 40 to the side of the joining object 41 toward smaller. Further, for a workpiece-side surface of the take-up device 40, a plurality of tips in which a plurality of protrusions are stacked in a 2-step, 3-step, or a multi-step manner may be provided. In the vicinity of the tips 6 of the receiving device 40 formed of the large projections 7 and the small projections 82, a peripheral header, the illustration of which has been omitted, may also be provided. The amount of protrusion of the peripheral projection, which has been omitted, from the surface of the pickup 40 becomes smaller than the amount of the protrusion of the tip 6 from the surface of the pickup 40, so that when joining, the peripheral projection, the appearance of which has been omitted, is omitted Joining object 41 can be damaged, pushed in and joined.
Further, tips may be provided from a plurality of 2-stage, 3-stage or multi-stage superimposed projections on either the resonator 1 or the receiving device 40 or both. For joining the joining object 41, it is also possible to remove the holder 35 from the dispensing element 34 in FIG. 1, to remove the receiving device 40 from the device frame 32, to attach the remote holder 35 in the lower section of the device frame 32 so that the tips 6 move upwards are directed to provide the receiving device 40 in the upper portion of the device frame 32, so that the remote receiving device 40 mounted on the output member 34 and the tips of the receiving device 40 are directed downward, and to provide the resonator 1 and the bracket 35 in the lower portion of the device frame.
2, the structure is explained in which the tips 6 of the resonator 1 are formed according to an embodiment of the invention in two stages from the large projections 7 and the small projections 8. As shown in the view A in Fig. 2, the large projection 7 when viewed from the top 6 from the bottom half-round rod-shaped, but it may also be circular. The outer sides of the two ends in the longitudinal direction of the semicircular-shaped large projection 7 are formed as convex curved surface portions 71.

That is, the outer sides of the two ends of the small protrusion 8 in the longitudinal direction have no sharp edges due to the convex curved surface portions 81 shown in the view B in Fig. 2 and form convex curved surfaces, from the side of the resonator 1 to the outside protrude. The vertically directed position of the central portion, which at the convex curved surface portions 81 describes a convex circular arc surface, may either be in the same position as the convex curved surface portions 72 or deviate from them.

As shown in the view B in Fig. 3, the foot portions of the large projection 7 on the longitudinal side are formed as concave curved surface portions 73. The concaved surface portions 73 delimit the convexed surface portions 71 from the workpiece-side surface 5 by describing a smooth concaved arc from the large projection 7 side to the workpiece-side surface 5. That is, the foot portions of the large projection 7 have due to the concave curved surface portions 73 no sharp edges and consist of a concave curved surface which is curved from the outside to the side of the resonator 1 inwardly. Further, the foot portions of the small protrusion 8 are formed in the longitudinal direction as concave curved surface portions 83. The concaved surface portions 83 delimit the convexed surface portions 81 and the convexed surface portions 72 by describing a smooth concaved arc from the side of the small projection 8 to the side of the large projection 7. That is, the foot portions on the longitudinal side of the small protrusion 8 have no sharp edges due to the concavely curved surface portions 83 and consist of a concavely curved surface which is curved inwardly toward the resonator 1 side from the outside.
As shown in the view C in Fig. 3, the foot portions in the transverse direction of the large projection 7 as concave curved surface portions 74 are formed. The concaved surface portions 74 delimit the workpiece-side surface 5 from the convex-surface portions 71 by describing a smooth, concaved arc from the side of the large projection 7 to the workpiece-side surface 5. That is, the foot portions of the large projection 7 have due to the smooth transition of the view B and the view C in Fig. 3 shown concave surface portions 73 and 74 to each other no sharp edges and consist of a concave surface, of the Outside is curved inward toward the side of the resonator 1. As a result, no breaks occur at the foot portions of the large projection 7 as a result of the ultrasonic vibrations or sound vibrations during joining. Further, the foot portions of the small protrusion 8 are formed in the transverse direction as concave curved surface portions 84. The concaved surface portions 84 delimit the convexed surface portions 71 and 82 by describing a smooth concaved arc from the side of the small projection 8 to the side of the large projection 7. That is, the foot portions of the small projection 8 have due to the smooth transition of the view B and the view C in Fig. 3 shown concave surface portions 83 and 84 to each other no sharp edges and consist of concave surfaces, which from the outside are curved inwardly towards the side of the resonator 1. As a result, no breaks occur at the foot portions of the small projection 8 due to the ultrasonic vibrations or sound vibrations during joining.
