[0002] In modern intelligent manufacturing systems, depalletizing is a critical step in material handling, and its automation level directly impacts production line efficiency and overall operating costs. The current mainstream solution primarily utilizes fixed end effectors coupled with industrial robots. While this configuration can achieve basic automation functions, it has significant limitations.

[0003] In existing multi-station automated production lines, robot depalletizing generally uses one set of end pickers for one specification of parts, resulting in a single application. The end pickers need to be stored and numbered in separate locations, which is costly. Some small incoming parts are stacked side by side and need to be manually separated before processing, which increases the operating process. In addition, when processing two parts at the same time, the gripping spacing cannot be adjusted, and special tooling needs to be made for centering the loading, which increases costs. For the processing of new parts, the end picker needs to manually insert and remove the suction cup and air pipe to match the part position, which is time-consuming and labor-intensive.
