Abstract:Taking welding robot as the research object, a welding robot workstation is built by using SolidWorks modeling function and RobotStudio simulation function.According to the actual working conditions of the welding parts, setting the parameters of the welding system, it was found that the short-circuit transfer welding method was suitable for the welding of thin plate low carbon steel. The power supply and gas supply system was designed, and the welding trajectory was planned. In order to improve the accuracy of the robot,Tool Center Point (TCP), Z and X methods were used to establish tool coordinates, and three-point method was used to set workpiece coordinates. The common Input Output (I/O)signals were created and correlated. The welding program was completed by using the special programming instructions of the welding robot. Collision monitoring was created to ensure that no collision occurred between the torch and welding parts during teaching and simulation. TCP tracking function was used to verify the accuracy of weld trajectory,to call timer function,and torecord welding simulation time. The welding parameters were continuously optimized in the production screen of the teaching device, so that the ideal welding seam could be obtained. Through the simulation design of welding workstation, it is helpful to improve the working conditions and production efficiency.
