Description

TECHNICAL FIELD

[0001] The application relates to the field of automobile part spraying technology, and particularly relates to a spraying device for automobile part surface treatment. BACKGROUND

[0002] Spraying technology plays an important role in the field of automobile manufacturing and maintenance, which not only adds beauty to the automobile, but also protects the automobile body from external factors. Automobile spraying is a complex and precise process involving many processes and principles. One of the purposes of automobile part spraying is to provide a protective coating for automobile parts to prevent the parts from being affected by corrosion and oxidation. When driving, the automobile encounters air resistance. The faster the automobile, the greater the air resistance. The shark fin of the automobile part can reduce the effect of air resistance on the vehicle. Even though many vehicles are now equipped with special spoiler devices, the shark fin still plays a good spoiler role.

[0003] After the shark fin is processed, the surface of the shark fin needs to be painted to improve the surface performance and aesthetic performance of the shark fin. During the spraying process of the shark fin, the shark fin needs to be fixed. In order to allow the paint to adhere well to the surface of the shark fin, the surface of the shark fin needs to be polished to make it smooth before spraying, thereby improving the quality of the shark fin after spraying. However, the current spraying device cannot stably fix the shark fin during the spraying process, and cannot shield the bottom of the shark fin after fixing, causing the installation bottom of the shark fin to be sprayed with paint, which affects the adhesion of the shark fin to the automobile during the subsequent installation process, reduces the quality of the shark fin after spraying, and simultaneously cannot adaptively change the spraying area according to the shape of the shark fin during the current all-around large-area spraying, which causes some paint to not be fully sprayed onto the shark fin, resulting in waste of some paint. In addition, the spraying device cannot pre-polish the surface of the shark fin before polishing, and the shark fin needs to be manually placed on the polishing mechanism for polishing, which reduces the spraying efficiency of the shark fin. In addition, the outer surface of the shark fin is curved, and it is difficult to fully polish the surface of the shark fin during the polishing process, resulting in poor polishing effect and poor spraying effect on the surface of the shark fin.
