The programming methods of welding robots mainly include teaching programming, offline programming and autonomous programming.
Teaching programming: This is a method that uses a manual method to move the robot end welding gun to track the weld using a teaching board, and timely record the weld trajectory and welding process parameters of the weldment. The robot reproduces the welding process by teaching point by point based on the recorded information. The teaching programming method includes teaching, editing and trajectory reproduction, which can be achieved through teaching box teaching and guided teaching. Since the teaching method is practical and easy to operate, most robots use this method.
Offline programming: This method uses some sensing technology, mainly relying on computer graphics technology, to establish a robot working model, perform three-dimensional graphics animation simulation on the programming results to detect the reliability of programming, and finally pass the generated code to the robot control cabinet to control the robot operation. Unlike teaching programming, offline programming has nothing to do with the robot, and the robot can work as usual during the programming process. Offline programming can reduce the working time of the robot, and combine CAD technology to simplify programming.
Autonomous programming: This is the basis for realizing robot intelligence. The application of various external sensors enables the robot to fully perceive the real welding environment, identify welding table information, and determine process parameters. Autonomous programming technology is a manifestation of advanced applications of welding robots, which can improve the degree of automation and welding quality.
