Connect the end effector quick-insert structure 59 to the robot through standard quick-insert parts. The suction cup assemblies of the quick-change end effector assemblies of multiple groups of end effector quick-insert structures 59 jointly grab and transport the part. By adjusting the galvanized pipe and the suction cup assembly, ensure that the suction cup fits the part surface, the end effector grabs the part firmly, and ensure stable automated production.
