Spray painting as an important part of the modern product manufacturing process, not only plays a beautiful, protective, and other special role, but also increasingly become an important part of the product value. In the furniture, aerospace, military industry, and other fields occupy an important position. The intelligent spraying robot is a complex electromechanical system composed of computer, sensor, vision and intelligent control technology. As the core of intelligent spray-painting technology, the development of intelligent spraying robot is closely related to the application of new materials, new designs, and new methods. Aiming at the common problems of key technology research of intelligent spraying robot, the current research achievements are summarized from the aspects of the mechanism design of spraying robot, dynamic performance monitoring of spraying system, automatic planning of spraying trajectory, and spraying quality inspection. Then the challenges of robot mechanism design and flexible spraying system integration in the process of intelligent spraying system are analyzed and discussed. Finally, the future development direction of key technology research of intelligent spraying robot is prospected and summarized, which provides a reference for the development direction of spraying robot and the improvement of key technology performance, and promotes the overall intelligent spraying technology.
