Abstract: A laser tracking system for the welding robot of the side wall of aluminum alloy car body is introduced. The system mainly includes robot system, laser tracking system, Longmen walking system, welding system, side wall installation system and central control system. Using the laser tracking system, the position and shape data of the weld can be detected, and the walking path and welding parameters of the robot can be adjusted in real time. An experiment system was designed to test the laser tracking signal and welding signal interworking technology, laser tracking data and welding real-time data logic analysis model, and verified the effectiveness of the system design. With this system, effective feedback can be made on the operating conditions of the welding equipment, the travel path of the welding torch, and welding parameters. And it can avoid the occurrence of the bad results of welding and the scrap welding work pieces.
