Intelligent Spraying Robot: Current Status and Future Perspectives from the Perspective of China

Abstract

Background: Spraying, as an important part of industrial production, is a labor-intensive industry. Manual spraying is greatly influenced by the personal factors of the operators. Furthermore, there are some problems in this method, such as substandard environmental protection and unstable spraying quality. However, intelligent spraying robots can effectively improve the efficiency of spraying, safety, environmental protection, flexible production, and high-quality spraying and reduce labor requirements. Therefore, the development trend of intelligent spraying robots has received increasing attention. Objective: In order to solve the problem that manual spraying is harmful to workers and is inefficient, the joint-type and non-joint-type intelligent spraying robots are constantly improving. Methods: The patents of intelligent spraying robots are summarized. The structural characteristics, advantages, and disadvantages of various intelligent spraying robots are introduced. Results: By investigating the patents of intelligent spraying robots, the main problems, such as poor manufacturing ability of high-end parts and insufficient software research and development, are summarized. In addition, the development trend of intelligent spraying robots is also discussed. Conclusion: The analysis shows that the intelligent spraying robot is an efficient and safe pioneering work. Compared with manual spraying, it has a very broad application prospect in various industrial spraying and is helpful to the development of the manufacturing industry.
