At this time, the output end of the latch locking cylinder moves downward, and the output end of the latch locking cylinder drives the locking latch to move downward through the floating joint and the oil-free bushing to be plugged with the bushing. At this time, the robot drives the frame to flip over through the tool quick-change disk and then transports it to the destination. Since the locking latch is plugged with the bushing, the product is always in a clamped state, thereby avoiding the clamping claw cylinder from being de-energized or accidentally opened, causing the product to fall. When it is necessary to grasp products of different models, the tool quick change plate is removed from the external robot, and the tool quick change plate of the appropriate size is installed on the external robot, so as to achieve rapid switching of the grippers for flexible production.
