Abstract

Disclosed is a simplified tray loader for semiconductor modules that can be used in conjunction with any module-handling apparatus. The simplified tray loader has fewer moving parts than existing tray loaders, resulting in more reliable operation with less down time. Referring to the figures, the tray loader 10 includes a main plate 12 upon which an empty tray 14 is manually loaded. Loader bar 16, which is affixed to main plate 12, aligns the tray with respect to a module feed track 18. Clamp 20, which is also affixed to the main plate 12, is manually locked down to maintain the tray 14 in its proper position. Additionally, clamp 20 depresses the tray spring at the end of tray 14 so that modules 22 can be loaded into the tray. Modules 22 fall into tray 14 until photodetector 24 detects a full tray.

Simplified Tray Loader

Disclosed is a simplified tray loader for semiconductor modules that can be used in conjunction with any module-handling apparatus. The simplified tray loader has fewer moving parts than existing tray loaders, resulting in more reliable operation with less down time. Referring to the figures, the tray loader 10 includes a main plate 12 upon which an empty tray 14 is manually loaded. Loader bar 16, which is affixed to main plate 12, aligns the tray with respect to a module feed track 18. Clamp 20, which is also affixed to the main plate 12, is manually locked down to maintain the tray 14 in its proper position. Additionally, clamp 20 depresses the tray spring at the end of tray 14 so that modules 22 can be loaded into the tray. Modules 22 fall into tray 14 until photodetector 24 detects a full tray. Internal logic illuminates reset switch 26, informing the operator that a tray is full. Additionally, all modules are blocked from entering the tray loader until the filled tray has been replaced and switch 26 reset. Another photodetector 28 continuously monitors the position of tray 14 to ensure that it is positioned properly.
