Electronic Component Assembly Apparatus

This apparatus inserts multilead circuit modules of mixed sizes into circuit boards and spreads some leads into module-retaining positions.

Circuit board 100, which is to be populated with circuit modules 101, is mounted on X-Y indexing table 102. A plurality of magazines 105, having different widths for storing different size modules, are carried on magazine support 104 which is indexable on base 103 by rotating shaft 125.

In operation, a magazine 105 containing the desired module 101 and the corresponding module exit aperture 107 on slide 106 are aligned with insertion driver 108 and module guide 109. Guide 109 is moved by cylinder 119 toward one side of the module to adjust for module size. The module is fed from a magazine 105 by driver 112 of loading cylinder 116, which contacts a backing block 150. Then the front surface of the module abuts the back surface of guide 109, which includes a flat spring 201 to aid in holding the module just before insertion into board 100.

Cylinder 120 adjusts anvil support 110 to bring into position one of anvils 111 corresponding to the size of the module, and the anvil is driven upward by cylinder 118 through cam 127. Subsequently cylinder 117 causes insertion driver 108 to move inside a slot of backing plate 130 and drive the module onto the anvil 111. This operation crimps some module leads, depending upon the shape of the anvil, and retains the module in position on the board 100 pr...
