The robotic automatic tool changer is used to service the robot peripherals in order to realize the robot's automatic replacement of different end effectors, thereby improving the flexibility of the robot application. Typically, the robotic quick changer includes a robot side (master disc mounted on the robot flange side) and one or more tool sides (tool discs mounted on the end effector). During the working process of the robot, the precise connection between the main disc and the tool disc is realized by the locking operation of the automatic tool quick change device.
