The Optimized Design of the Welding Gripper for the Body Pre-Assembly

In order to improve the efficiency of welding, the automotive body pre-assembly was implemented in an automatic welding line. The author designed a robot welding gripper for the pre-assembly station, and simulated the motion of cylinder on each unit by using the CATIA DMU module to inspect the interferences and optimize the structure. The practical application indicated this robot gripper could make good use of the high-accuracy and the flexibility of robots to handle workpiece accurately and assemble quickly.
