Description

Technical Field

[0001] This utility model relates to the field of material tray handling technology, and more specifically, to a multi-size compatible PACK tray loading and unloading mechanism. Background Technology

[0002] Die inspection technology is a crucial step in the semiconductor industry, primarily involving the detection of defects in chips (dies) (such as integrated circuit wafers). With the development of industrial automation, artificial intelligence, and precision measurement technologies, die inspection technology has evolved from traditional manual inspection to intelligent and high-precision automated inspection. Dies are stored in PACK trays of corresponding sizes. Our organization will load and unload the PACK trays containing dies and place them into cartridges for subsequent inspection or other processes.

[0003] In the existing technology, the modules that contact the PACK tray all use servo control to ensure high precision and stability, but the cost is also relatively high. Since different customers' PACK trays have different working conditions, the PU workpieces that the side push module contacts the PACK tray may stick and age after long-term use, requiring regular inspection and replacement, which affects the safety of handling and loading / unloading.

The vertical electric cylinder 103 descends to the unloading position of the flow channel 5, and the electric gripper 106 opens (the PACK disk 6 is placed in the unloading position of the flow channel 5). The vertical electric cylinder 103 then rises to the safe position, and the horizontal slider 102 moves to the spring-loaded material picking position.

[0049] In summary, this application is compatible with the loading and unloading of 2 & 4 inch PACK trays 6, and can realize the loading and unloading of the entire PACK tray 6 without contacting the DIE, enabling up to 40 PACK trays 6 to be loaded at one time. The magazine and side push module 4 have guiding and positioning functions, which greatly improves the efficiency and stability of the production line.
