The drive of the shutter mechanism is made in the form of a Maltese mechanism and installed with the possibility of selective interaction of the plate of the shutter mechanism with channels for the circuit elements. 46 The pin of the gripping mechanism is made with the number of holes corresponding to the number of channels for the circuit elements. The container is equipped with a rod installed in the opening of the lid with the possibility of blocking the opening in the bottom part of the container. FIG. 1 shows a device for feeding elements of electrical circuits, front view in vertical projection; in fig. 2 - the same, side view; in fig. 3-6 is the same, section A-A in FIG. 2. in various states; in fig. 7 is a section BB in FIG. 2 in FIG. 8 is a section bb of FIG. 2, in FIG. 9 - the same, during the adjustment of the number of elements by means of the slide-off, in FIG. 10 - the same, after completion of the shutter shift; in fig. 11 is the same, with the shutter open in FIG. 12 - the same, in the open state of the valves for feeding two elements, in FIG. 13 is a section of YYY in FIG. 1 in FIG. 14 - the same, in one of the operating states, in FIG. 15, a d-d section in FIG. 13. The device for feeding the circuit elements comprises a cylindrical container 1 for the circuit elements made of transparent plastic,. provided with a conical bottom plate 2 with a through hole 3 in the center. The device includes a neck 4 of the container 1, a stable supporting element 5 which has a support bracket 6 mounted on its upper end. The ring-shaped support part 7 of the bracket 6 supports the neck 4 of the container 1. The ring-shaped support part 7 includes a vertically passing slot 8 and is equipped with a clamping mechanism 9 for clamping the neck 4 of the container 1. The upper end of the container 1 is open and is closed with a disc-shaped lid 10 removably fixed thereto by means of screws 11. The lid 10 is centered cial part provided with a sleeve 12 formed with a central drilling 13, the transition in conductive through-bore 14 of smaller diameter. The threaded drilling 13 and the through drilling 14 are intended for the rod 15, the second one
    It is threaded through hole 14 and is connected by screwing a part with an external thread 16 into an internally threaded hole 13. A rod 15 connected in this way passes into the through hole 3 of the container and covers the bottom part.
    The movable assembly 17 is located below the container 1 for reciprocating movement along 18 and right 19 vertical rods. The node 17 is vertically reciprocated by an external drive (not shown) via the communication element 20. The movable node 17 includes a pair of vertical rods 21 that have a support plate 22 attached to their upper ends.
    The gripping mechanism 23 of the circuit elements is mounted on the base plate 22 and serves to grip the elements in the container 1 and feed them to certain positions for assembly on the integrated circuit board. The gripping mechanism 23 has a cylindrical shape and is preferably made of synthetic resin, for example Teflon. The gripping mechanism 23 has a conical part of the frontal surface, made with three axial drills 24, opening at their upper ends in the conical surface 25 of the gripping mechanism and connected with lower ends with connecting pipe 26 embedded in the gripping mechanism 23. Connecting pipe 26 with its lower end connecting with tubing 27 made of Teflon.
    The gripping mechanism 23 vertically and reciprocatingly moving the reciprocating movement of the movable node 17. During this movement, the gripping mechanism 23 slides up through the opening 3 of the neck 4 in the container 1, and the circuit elements inside the container 1 are gripped inside the gripping mechanism 23 by through holes 24 in a conical frontal surface 25. The frontal surface 25 of the mechanism 23 has a taper angle, for example, 60 °.
    The shutter mechanism includes a guide plate 28 attached to the lower end of the movable node 17. The guide plate 28
    made with a recess 29 formed in its upper surface (the surface in contact with the node 17), and the shutter 30 is movably located inside this space. The shutter 30 is fastened to the supporting plate 31 (moving left and right) by a pair of rods 32 fixedly attached to the block 33 moving
    in the horizontal direction. The movable unit 33 is mounted to move up and down on a pair of rods 34 connected to it. Horizontally movable block 33
    also provided with a support bracket 35, made in one piece with it. The motor 36 is supported on the bracket 35 horizontally by the movable block 33.
    The motor 36 has an integral downshift for providing a lower speed for the output shaft of the motor, which has a cam washer 37 fixedly mounted on it.
    In the cam washer 37 there is a triangular groove 38, inside which the working part of the microswitch element 39 is mounted. Pin
    40 is mounted on the lower surface of the cam plate 37 and is hooked by the radial grooves of the Maltese mechanism (Maltese cross) 41 in order to intermittently rotate the latter 90 each time it triggers. The Maltese cross 41 is mounted on a horizontally movable block 33 rotatably and fixed to the drive gear 42, which,
    in turn, it is in engagement with a toothed rack 43 fixedly attached to the end of the supporting gate plate 31. Therefore, when the electric motor 36 is actuated supporting the slide plate, the tin 31 moves left and right through the Maltese cross 41 , leading, gear 42 and the rack 43.
    The movement of the shutter support plate 31 is detected by an optical detection means, including -. the black-painted light-shielding rods 44, motionless
    attached to the bottom surface of the shutter support plate 31. Light-enclosing rods 44 are located between the supporting plates 45 and 46 so that the position of the shutter-supporting plate 31 is detected by light sources 47 with light-sensitive elements (48 installed on the supporting plate 46, The shutter 30, which is preferably made of stainless steel sheet, has at its front end an L-shaped notch 49 that regulates the number of circuit elements supplied by each stroke. The shutter 30 is located between at three through holes 50 for the circuit elements formed in the movable node 17, and three through holes 51 for the schematic elements formed in the guide plate 28, for selectively interrupting communication between these through channels. In the through holes for the circuit elements formed in the movable An assembly 17, preferably made of steel, is provided with a sleeve 52 made of an anti-magnetic material, such as phosphor bronze, which prevents any magnetic interference between the channel, cap E ast and the electrodes on either end of circuit elements. One of the tubes 27 is connected to the upper end of each bore 51 for the circuit elements, which in the guide plate 28 are made up of tubes 53 which are attached to a through hole inside the guide plate 28, each tube 53 connected to the plate 54 base at pipe 11, pipe 55. Each of the three through holes 50 for the circuit elements is provided with a small diameter hole 56, which nepeceKaet hole 50 at a right angle. The pin 57 is installed inside a small-diameter hole 56. Each pin 57 is slidably supported by a connecting plate 58, which in turn is supported by the ends of the rods 34 and is elastically displaced by coil springs 59, which act on one end of the connecting plate 58. Thanks to this force, each pin 57 holds the circuit element 60 in the corresponding through hole 51. The element 60 rests on the element, directly supported by the gate. Therefore, only a circuit element that is in a state of direct contact with the gate can fall even when the gate is open. The proposed device operates as follows. I Pre-selected circuit elements 60 are placed in container 1. Each of these elements has a cylindrical shape and a certain size. The gripping mechanism 23, passing through the through hole 3 in the bottom of the container, moves up and down relative to the container 1 as the movable node 17 moves up and down the rods 18 and 19. In this case, the gripper node 23 moves through a group of circuit elements 60 stored in the container 1. The elements 60 are caught by three through-holes 24 in the conical surface 25 of the gripping mechanism 23. Circuit elements 60 held in through-holes 24 maintain a constant upright position to allow subsequent movement of these parts. As the gripping mechanism 23 moves along the axis of the container 1, only those schematic elements that are located along the centerline move, which minimizes the likelihood of damage. Since the circuit elements 60 are taken out of the container 1 by the movement of the gripping mechanism 23, the feeding device operates at a reduced level of vibration and noise compared to the standard vibration type feeding devices. Furthermore, since the circuit elements 60 are not transmitted by vibration, the caps of the circuit elements and the electrodes passing at each end of the circuit elements 60 are not affected by vibrations and collisions, therefore the likelihood of their damage is reduced. When changing the type of circuit elements 60, the container is replaced. The insertion rod 15 is inserted into the container 1 through the through-hole 14 of the lid 10 and screwed into it, closing the lower end of the container. 1 and a through hole 3. The conies of the undercut 61 formed at the lower end of the insertion rod 15 fits tightly onto the conical end of the gripping mechanism 23 and prevent further supply of any circuit elements. Then the clamping mechanism 9 is loosened, and the container 1 is carefully removed in the axial direction, freeing from the clamping mechanism 9. Another installation of the other container is carried out, repeating the described operations in the reverse order. After pulling out the plug-in strap 15, the new container 1 is supported by the supporting part 7 of the supporting bracket 6, and the clamping mechanism 9 is tightened, fixing the new container 1. This eliminates the need for unloading containers and loading them with other types of circuit elements. The circuit elements 60 are taken from the container 1 by the grip mechanism 23 and are moved to the position of the gate fur by the force of gravity through the tube 27. These elements are successively transferred to the next stage of the working process by opening and closing the bolt 30. 33 is driven by a driving means (not shown) and moves in a horizontal direction relative to the movable node 17, since the rods 34 fixedly attached to the horizontally movable block 33 are guided and supported live for free sliding movement with respect to node 17. Since the horizontally mobile unit 33 carries on itself the supporting gate plate 31 through a pair of rods 32, its movement in the axial direction of the rods 34, i.e. upwards, forces the lifting of the supporting shutter plate 31. Because of this, the edge of the shutter 30 is seen from a position corresponding to the bore hole 50 for the elements, in such a way that the three bore holes 50 and the three bore holes 51 can communicate with each other. Three bore holes 51 communicate with three bore holes 24 of the gripping mechanism 23, therefore, the elements inserted into the locking mechanism through holes 50 can freely fall into the corresponding through holes for the elements 60, each hole 50 for the elements 60 supplies only one element 60 when the shutter 30 opens. Thus, when the horizontally movable block 33 is moved, opening the shutter 30, the connecting plate 58 connected to the ends of the rods 34 fixedly attached to the block 33 moves to the left, compressing the coil spring 59. As a result, the pin 57 moves to the left by the elastic shearing force of the spring 59, pressing the element 60, which is directly above the element 60, which is located on the bolt 30 itself, to the wall of the through hole 50. Thus, the second and next elements 60 are prevented from falling onto the gate 30 and only one circuit element is dropped into the passage opening 51 for the elements 60.. The number of circuit elements supplied in one stroke of the gate 30 can vary, depending on the requirements, from zero to three. The motor 36 is started when the Maltese cross 41 is rotated by means of a cam washer 37 and pin 40. Turning the Maltese cross 41 90 moves the support plate 31 in the longitudinal direction of the rods 32 due to the action of the pinion gear 42 and the toothed rack 43 for a distance corresponding to one passage length holes 50 and 51 for the elements. Since the shutter 30 includes an L-shaped recess 49, only two groups of through holes 50 and 51 for the elements of the three are allowed to communicate with each other when the shutter 30 moves horizontally by the movable unit 33 in the opening direction, i.e. up. As a result, two circuit elements 60 are supplied with one stroke of the shutter 30. The offset of the position of the shutter 30 to control the number of circuit elements to be supplied is achieved by actuating the Maltese cross 41 by means of the electric motor 36. The offset of the shutter 30 is accurately detected when the light-spreading rod 44 is blocked The light emitted by an appropriate source therefore the shutter 30 stops at a precisely defined position. The Maltese cross 41 is rotated 90 when the cam washer 37 makes one full revolution, and the completion of one full revolution of the cam washer is detected by the interaction of the recess 38 of the cam washer 37 and the microswitch 39.
    When the Maltese cross 41 is rotated another 90 °, the number of elements supplied by one stroke of the gate from the feed installation is reduced to one. Further turn on
    12224610
    90 of the Maltese cross 41, the electric motor pulls out the L-shaped recess 49 of the shutter 30 to move to a position on the right side of the right 5 bore 51 for the elements 60, as indicated by a two-dotted line. In this state, the circuit elements 60 are not supplied even when the shutter 30 moves to the open
    10 position.
    The device provides an increase in the quality of work by reducing mechanical interference during the installation of integrated circuits.
