Problems solved by technology

[0002] In the process of metal plate processing, surface coating treatment is a common processing method, but the common metal plate needs to use paint or other coatings for surface processing, and it is difficult to control the thickness of paint or paint during the treatment process. At the same time The color is easy to be uneven or the color is prone to deviation, especially when the surface processing of some metal texture colors is very demanding on the color, if the treatment is not good, it will easily lead to an increase in the defect rate, and needs to be improved
[0003] Chinese Patent No. CN103526161A discloses a vacuum coating method, by enclosing a base material into a cylindrical structure, the outer surface of the cylindrical structure is the surface to be coated, by rotating the coating twice before and after Coating, the coating material is evaporated onto the substrate in a vacuum chamber, which can eliminate the influence of the distance from the source of the coating material to the surface to be coated or gravity on the thickness of the film, and can achieve a large area of ​​uniform coating on the surface of the substrate. The strip-shaped substrate is spirally wound into a cylindrical structure, which can achieve uniform coating on the surface of the strip-shaped substrate with large length and small width. It has the advantages of high coating efficiency and simple production equipment. However, the overall process It is relatively complicated, which leads to higher overall processing requirements, and also increases the cost virtually, so it needs to be improved
[0004] Chinese Patent No. CN102383101B discloses a composite vacuum coating method, which uses magnetron sputtering ion plating hybrid coating technology to obtain high film density, bright white surface, strong metallic feeling, good physical properties and stable Chemical performance, its performance is superior to traditional electroplated aluminum alloy / zinc alloy products, because vacuum dry plating is used to replace traditional wet plating, the metal layer on the surface is deposited by vacuum coating, avoiding toxic metal substances such as hexavalent chromium The emergence of the new technology has reduced the pollution to the environment, significantly reduced the energy consumption, water consumption and the consumption of precious metals, but for the special requirements of metal texture color coating, it still cannot meet the requirements and needs to be improved
