Research on Teaching Free Welding Workstation for Overlength Workpiece
In the application of automatic robot welding, certain limitations exist in teaching and off-line programming. Based on the welding requirements of overlength workpiece, an automatic integrated conveyor for overlength workpiece is studied to realized the automatic transmission, welding, and unloading of workpieces; A separate pressing fixture for welding overlength workpiece is studied to solve the problem of taking out the shrinkage deformed workpieces; The application of teaching-free six-axis welding robot in overlength steel structure, multi-point and small angle welding is also studied to form a set of automatic welding workstation. This workstation integrates the vision, force, antenna and other sensors of the robot with the help of the automatic assembly line, welding robot, visual inspection, etc. Then, according to the information feedback of the sensors, the motion decision of the robot can be adjusted in real time to achieve automatic teaching-free welding.
