Abstract: In view of the high cost, long cycle and low autonomy caused by the dependence of integrators in the construction of automobile welding workshop, this paper puts forward a six-step self-reliance implementation path of "model establishment, joint definition, movement relationship configuration, three-dimensional layout construction, robot debugging, offline program test" based on process simulation technology. Through the process designer process simulate (PDPS) platform, taking the automation transformation project of the back cover of a welding workshop as an example, the system explains the whole process autonomous simulation method from equipment model configuration, simulation workstation construction, offline debugging and optimization to on-site online operation. Practice shows that this scheme can realize the accurate planning of the robot welding trajectory, the virtual prediction of collision risk and the efficient export of offline programs, effectively improve the autonomous control ability of enterprise process simulation technology, and provide an empirical basis for automobile manufacturing enterprises to promote technological self-reliance, reduce the cost of external cooperation, and reconstruct the competitiveness of the value chain.
