[0002] Paint spraying refers to the uniform spraying of paint on the surface of an object and curing to form a coating for decoration or protection. Paint spraying is applied in many fields such as machinery, automation, material chemical industry, etc. For example, paint spraying is used for corrosion protection of mechanical parts; paint spraying is used for coloring and beautifying toys, etc. Traditional paint spraying is usually performed by hand-holding the object to be painted and spraying paint with a spray gun. Alternatively, the spray gun is hand-held to spray paint on different sides of the object to be painted. Since paint is a mixture of many organic components, its raw materials are mostly toxic and volatile organic solvents, which are easy to touch or inhale during manual spraying, causing contact with human skin or mucous membrane and possibly causing serious harm to human health. Therefore, protective masks, eye shields and even protective clothing need to be worn when manual paint spraying is performed, which is inconvenient and still has the risk of contact. On the other hand, manual paint spraying is low in efficiency and slow in processing, which is not conducive to industrialization. At the same time, in order to increase the uniformity of spraying, paint is atomized into fine liquid particles as much as possible during spraying, which is easy to diffuse and evaporate in the air during the spraying process, resulting in a large amount of paint waste and air pollution.
