Abstract: The article expounds the problems encountered by the spraying robots in the self-profiling and debugging process of the new vehicle model at the auto-coating factory and its corresponding solutions. It focused on solving the problems such as substandard spray amplitude overlap rate, robot limit position (dead axis), color difference and robot collision when it is without adding the spray robot, other equipment and reducing the production cycle and ensuring the normal production of the production line. The methods of optimizing the profiling trajectory, robot posture, changing the spraying speed, adjusting the film thickness, solid content and the secondary film-forming ratio of color paint were used to make the appearance quality of new vehicle model meet the standard, and finally ensured the successful production of new vehicle model in the automobile coating plant.
