    Limitation for placing electronic components on a surface
    The invention relates to a storage table for inspection and / or alignment of electronic components prior to equipping a printed circuit board with these components.
    PCBs are currently mainly equipped with the SMT method with electronic components of very small dimensions for the production of electronic Llachbaugruppen. The loading is usually done with placement machines, the components are usually taken from supply belts by suction on a placement. In many cases, the component is placed on a storage table, on which it can be aligned or inspected. After the inspection or the alignment, the component is again picked up by an arm under oppression and placed in the correct position on the board to be populated. Alignment is required, on the one hand, with regard to the correct position of the solder connections, but in particular with components which have sensor surfaces or light emission surfaces, in particular LEDs, also with regard to the correct position of the sensor and light emission surfaces.
    It has been found in practice that by unwanted air currents, but in particular by the air flow of the arm, which holds a component by suction or by pressure reduction or pressure increase the component releases again, slipping of the component can occur on the tray, which leads to undesirable business interruptions of an automated assembly process.
    An object of the invention is to provide a filing table, in which the mentioned disadvantages can be avoided.
    This object is achieved with a storage table of the type mentioned, in which according to the invention, the table has a transparent shelf, preferably a glass plate, and a displacement of a temporarily stored on the support member border limiting is provided.
    Thanks to this design of the tray table a stored component is kept safe in a defined area, so that it can be checked, for example by means of optical sensors both from above and from below and also an alignment in a predefined
    Location is possible. It can also be a new place in a corrected positioning.
    In an advantageous embodiment it is provided that an auxiliary plate is provided with at least one continuous recess on the tray, wherein the limiting border is formed by the walls of the at least one recess. Such an auxiliary plate can be easily placed in the desired size and training on the shelf of the tray. It is advantageous if the auxiliary plate is transparent, so that optical sensors are disturbed as little as possible by light-reflecting or light-absorbing parts.
    In a variant of the invention it is provided that in the transparent tray at least one recess for receiving at least one component is formed, wherein the limiting border is formed by the walls of the at least one recess. Such a design is particularly advantageous when essentially many components of the same dimensions are used, since one can do without an auxiliary plate here.
    In many cases, it is recommended that the border is substantially circular, as this is a universal applicability with little turbulence of air or gas streams is given.
    On the other hand, it may also be advantageous for better fixing of components, if the border polygon, preferably rectangular or square, is formed.
    The invention together with further advantages is explained in more detail below with reference to exemplary embodiments, which are illustrated in the drawing. In this show
    1 schematically and diagrammatically a recessed in a storage table tray,
    2 Schematic the setting and setting of a component on a shelf,
    3a to c in plan view different geometries of the limiting border,
    Fig. 4 diagrammatically and schematically the arrangement of limiting walls around a component and
    Fig. 5 shows a variant in which a recess in the transparent tray is formed.
    Fig. 1 shows schematically a storage table 1, in which a storage plate 2 is inserted. This shelf 2 is preferably made of glass and is therefore transparent.
    On the shelf 2 is preferably a likewise transparent auxiliary plate 3 with a recess 4, which is formed in the present case circular cylindrical. Within this recess 4, a component B may be located, which is thus surrounded by a cylindrical border 5 formed by the recess 4. The component thus secured by the border 5 against extensive slippage can be inspected, for example, by an upper optical sensor 6 and by a lower optical sensor 6u, here through the depositing plate 2. The optical sensors can be, for example, cameras which supply alignment information with regard to the component to a computing unit for controlling the assembly process.
    In Fig. 2 is shown schematically how it can come to undesirable air currents, which move a component B. On the left in FIG. 2, it can be seen holding a component B through the nozzle end 7 of a robot arm, not shown in more detail, wherein the negative pressure, indicated by upward arrows, holds the component B. Held the component B is brought during the loading process to the tray and deposited there by the suppression in the nozzle 7 initially reduced and then - for safe settling of the component B - in an overpressure in the range of 1 to 100 mbar passes. This overpressure can lead to slipping or "blowing". a small and lightweight component B come.
    Fig. 3a shows a circular wall 8 in plan view, which results in a corresponding cylindrical border 6z for a component. In Fig. 3b four arranged in a square wall parts 9a to 9d are provided, which together form a border 6p in the form of a square prism for a component. On the other hand, FIG. 3 c shows a wall array 10 which provides a total of four borders for components of different dimensions and geometries and is universally applicable.
    Fig. 4 shows the arrangement of wall parts 9a to 9d - mutatis mutandis corresponding to Fig. 3b - around a square member B around.
    Finally, Fig. 5 shows an embodiment in which directly in the tray 2, a recess 11 is formed, in which a component can be accommodated. In the present case, this recess is circular in plan view and forms a cylindrical border 12th
