[0002] PVD---Physical Vapor Deposition: refers to the process of transferring atoms or molecules from a source to the surface of a substrate by using a physical process to achieve material transfer. Its function is to spray certain particles with special properties (high strength, wear resistance, heat dissipation, corrosion resistance, etc.) on a matrix with lower performance, so that the matrix has better performance. Basic PVD methods: vacuum evaporation, sputtering, ion plating (hollow cathode ion plating, hot cathode ion plating, arc ion plating, active reaction ion plating, radio frequency ion plating, DC discharge ion plating). Existing 3D surface structure products have uneven coating when processing PVD.

[0003] For example, Chinese patent document 202320822090.7 discloses a golf club PVD jig, which comprises a first gear and a second gear, and a sleeve is arranged on the second gear, wherein the sleeve is used to fix the golf club. During processing, the golf club PVD jig is installed on a rotating mechanism, and the rotating mechanism can drive the PVD jig to revolve. While the PVD jig revolves, the power mechanism can drive the first gear to rotate, and the rotation of the first gear can simultaneously drive multiple second gears to rotate, thereby driving multiple golf clubs to rotate on their own. In this way, during PVD processing, the golf club can not only revolve so that the spraying mechanism can spray paint on each golf club, but also each golf club can rotate on its own, and different sides can be rotated to the side opposite to the spraying mechanism to be fully sprayed with an equal amount of paint, thereby finally obtaining a complete and uniform protective film, thereby ensuring the PVD processing effect of the golf club.

[0004] In the above technical solution, although the rotation operation is achieved, its transmission method does not adopt a continuous meshing method, which leads to problems such as low transmission efficiency and poor transmission stability. Utility Model Content
