Abstract

This is an improvement over the electronic component assembly apparatus described at pages 2917-2918 of the February, 1974, IBM Technical Disclosure Bulletin. A single multisection ram combines the functions of the insertion driver and module guide, to prevent feeding of more than one module at a time.

Electronic Component Assembly Apparatus

This is an improvement over the electronic component assembly apparatus described at pages 2917-2918 of the February, 1974, IBM Technical Disclosure Bulletin. A single multisection ram combines the functions of the insertion driver and module guide, to prevent feeding of more than one module at a time.

The ram has four independent sections engageable by indexing a selector block's slide in slots on adjacent ram sections. The selector block is indexed by a four-position cylinder to engage section 1; 1 and 2; 1, 2 and 3; or 1, 2, 3 and 4; depending on the size of module being handled. The engaged ram sections may then be driven vertically by an operating cylinder, to provide an appropriately sized window for the module and to drive the module down onto a circuit board.

The operating sequence starts with the selector engaging all of the ram sections, which are driven downward to entirely block all size modules. The selector is then withdrawn to engage only the desired ram sections, and moved upward to open a window corresponding to the current module size. The unengaged ram sections are held in their down position by detents. When a module is in the window, the engaged ram sections are driven downward.
