[0002] With the continuous development of science and technology, optical products have evolved from traditional flat components (glass lenses, filter plates) to spherical and cylindrical surfaces (optical domes, laser radars), etc. The requirements for coating are getting higher and higher. To meet the requirements of products with different curved surfaces, coating machines are mainly divided into two categories: the first category is a flat coating machine with a conical umbrella or an arc umbrella, which mainly produces flat and micro-curved products. The second category is a spherical machine with a planetary disk structure, which mainly produces large curved, spherical, and cylindrical products.
[0003] Of these two types of coating machines, the flat coating machine has a larger loading capacity at one time due to the structure of the workpiece plate, but the types of curved products that can be produced are greatly limited. Although the spherical coating machine is not affected by the curvature of the product, its loading capacity is greatly limited, resulting in increased costs, very low production efficiency, and very cumbersome adjustment.
[0004] In order to simultaneously obtain the loading rate on a flat-plate coating machine and the advantages of a spherical machine in producing spherical and cylindrical products, a magnetic pole-powered coating device for curved surface PVD is proposed. Utility Model Content
