[0002] The quick-change tray is also called the tool quick-change tray, gun change tray, quick-change tool tray, quick changer, quick changer, quick-change fixture, fixture quick changer, etc. in the industry. It is an end-of-arm tooling (EOAT) quick-change device, and is an important device used on robot arms in the field of industrial automation. It can facilitate the robot to quickly and easily replace different end effectors (such as fixtures, welding guns, manipulators, spray guns, suction cups, etc.) to adapt to different production tasks.

[0003] In the automobile manufacturing industry, a workstation often requires multiple robots equipped with a variety of tools to perform operations such as grasping and welding. In this case, more equipment is invested and the production efficiency is low. The accuracy of repeated positioning of grasping and placement cannot be guaranteed. When the robot is working, welding slag splashes, which has a probability of falling into the quick-change plate.
