[0002] A painting robot is an industrial robot specially used for automatic painting or spraying other coatings. These robots are mainly composed of a robot body, a computer and a corresponding control system. For hydraulically driven painting robots, they also include a hydraulic oil source, such as an oil pump, an oil tank and a motor. Painting robots usually adopt a 5 or 6 degree-of-freedom articulated structure, which gives their arms a large movement space and can perform complex trajectory movements. Its wrist generally has 2 to 3 degrees of freedom and can perform flexible movements. When existing painting robots need to perform assembly line operations, they often need to set up two groups of painting robot structures on both sides of the workpiece for spraying. It is not easy to spray the side away from the painting robot, and there is a tendency for spraying dead angles.
