[0002] Traditional car body painting operations mostly rely on manual operations, which are not only labor-intensive and inefficient, but also difficult to ensure the uniformity and consistency of the paint. At the same time, the working environment also has a certain impact on human health. With the development of automation technology, robots are gradually used in various industrial fields. Therefore, the development of a car body painting quilting robot has important practical significance.

The gantry type spray painting system that can process the curved surface on the top of a train can realize spraying. The gun performs horizontal and vertical linear motions to ensure that the distance from the spray gun to the workpiece is a constant value, so that the paint film thickness is uniform during spraying.
