Description

Technical Field

[0001] The utility model relates to a coating umbrella fixture, in particular to a vacuum coating umbrella fixture, belonging to the technical field of vacuum coating. Background Art

[0002] Vacuum coating refers to a method of heating metal or non-metal materials under high vacuum conditions to evaporate and condense them on the surface of the coated part to form a thin film, such as vacuum aluminum coating, vacuum chromium coating, etc.; existing evaporation equipment generally includes an evaporation source and a coating umbrella fixture arranged above the evaporation source to carry the coating substrate; during evaporation, the coating umbrella fixture rotates to make the film thickness of the coating substrate distributed at various locations of the coating umbrella fixture uniform.

[0003] However, during the use of the traditional vacuum coating umbrella jig, the placement holes arranged on it will use corresponding limit clamps to limit the plated parts when placing the substrate, and the placement of these limit clamps is mostly irregularly distributed. At the same time, when the processing is almost finished, sometimes there will be a few less plated parts on some placement holes, which will easily affect the center of gravity of the entire coating umbrella jig. In addition, since the umbrella piece is arc-shaped, it is easy to produce some slight deformation after long-term use, which further affects the center of gravity of the entire jig when it rotates, thereby easily affecting the stability of the coating umbrella jig when it rotates during work, which is not conducive to normal processing.
