Therefore, most of them adopt automated production lines. In the automated production line, the process of grabbing the blank bar material and sending it to the positioning processing, the process of secondary positioning and marking after the processing is completed, and the process of putting it into the material bin after marking, all these processes need to be completed by the robot hand grip unit. The robot hand grip unit needs to be installed with a gripping mechanism to complete the operation.
