Abstract

Semiconductor modules are stacked in elongated tubes for storage prior to their being tested. The invention disclosed herein is an automatic storage tube unloader which enables less operator handling of the storage tubes during the unloading operations. Fig. 1 is a side view of the unloader mechanism, and Fig. 2 is a cross-sectional view along the section line A-A' of Fig. 1. The module storage tubes 1 are vertically stacked on the platform 2 of the unloader mechanism. The storage tubes are aligned and positioned by means of the end guide 3. The tubes are loaded while the apparatus is in the horizontal position shown by means of the phantom lines in Fig. 1.

Module Handler Auto Load Mechanism

Semiconductor modules are stacked in elongated tubes for storage prior to their being tested. The invention disclosed herein is an automatic storage tube unloader which enables less operator handling of the storage tubes during the unloading operations. Fig. 1 is a side view of the unloader mechanism, and Fig. 2 is a cross-sectional view along the section line A-A' of Fig. 1. The module storage tubes 1 are vertically stacked on the platform 2 of the unloader mechanism. The storage tubes are aligned and positioned by means of the end guide 3. The tubes are loaded while the apparatus is in the horizontal position shown by means of the phantom lines in Fig. 1. The platform 2 is then elevated to an inclined position so that the modules contained inside the respective storage tubes 1 can be fed out of the chute 4 gravity toward the testing station. When a particular storage tube 1 at the bottom of the stack, shown in Fig. 1, has been emptied of its modules, the photodetector 5 will detect this situation and will energize the actuator 6 which displaces the tube 1 laterally, as is shown in Fig. 2, allowing the next lowest tube 1 in the vertical stack to occupy the lowest position so that the modules stored therein can slide by gravity out of the chute 4 toward the testing station. The empty tubes 1 will accumulate on the top surface 7 of the platform 2 and can be dropped off the edge of the platform, thereby providing a fully automatic...
