Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Referring to the accompanying drawings, a vacuum coating fixture includes an upper component 100 and a lower component 200 arranged above and below each other. The upper component 100 includes a first plate 11 and a second plate 12. The second plate 12 is disposed in the middle of the first plate 11. A gap 13 is provided between the first plate 11 and the second plate 12, and the gap 13 is the range of product coating.

[0028] Furthermore, it also includes a connector 2, which connects and fixes the first plate 11 to the second plate 12.

[0029] More specifically, the gap 13 in this application is annular in shape. The connector 2 includes a first connecting leg 21, a second connecting leg 22, and a third connecting leg 23. The top ends of the first connecting leg 21, the second connecting leg 22, and the third connecting leg 23 are connected to a connecting plate 24. The first connecting leg 21 and the third connecting leg 23 are respectively located at both ends of the second connecting leg 22. The bottom ends of the first connecting leg 21 and the third connecting leg 23 are connected to the first plate 11, and the bottom end of the second connecting leg 22 is connected to the second plate 12. In addition, a first hollow portion 31 is provided between the first connecting leg 21 and the second connecting leg 22, and a second hollow portion 32 is provided between the third connecting leg 23 and the second connecting leg 22. That is, in addition to connecting the first plate 11 and the second plate 12, the middle of the connector 2 is hollowed out. This hollowed-out design greatly reduces the amount of material while ensuring strength, and at the same time enhances stress dispersion and fatigue resistance, and to a certain extent enhances heat dissipation and ventilation.

[0030] Furthermore, both the upper component 100 and the lower component 200 have corresponding through holes 4 on their side ends, and also include fasteners that connect and fix the upper component 100 and the lower component 200 through the through holes 4. In the embodiments of this application, through holes are only provided in the middle of the side ends. Due to the fixing effect of the connector 2, the upper component 100 and the lower component 200 can be effectively fixed by the through holes 4 on the left and right sides, which facilitates disassembly and assembly.

[0031] Furthermore, it also includes a coating hanging rod with through holes 4 at both ends. It can also be connected to a rotating device that rotates in conjunction with the coating hanging rod to facilitate easier disassembly and fixing.

[0032] Furthermore, the lower component 200 is provided with a concave surface 5 of a corresponding shape according to the shape of the product to be plated, and the corner ends of the concave surface 5 are provided with positioning holes 6 for auxiliary material positioning. More specifically, the concave surface 5 of this application is rectangular, the positioning holes 6 are provided at the four corner ends of the concave surface 5, and the positioning holes 6 are circular in shape.

[0033] Furthermore, the concave dimension of the concave surface 5 is half the thickness of the product to be coated. When the concave surface dimension of the fixture is half that of the product, a more uniform electric field or vapor diffusion space can be formed, reducing the problem of uneven film thickness caused by spatial differences. Moreover, in magnetron sputtering coating, the magnetic field distribution is closely related to the fixture structure. A concave surface of a reasonable size can guide the plasma to bombard the product surface more uniformly, improving the adhesion and density of the film layer.

[0034] This application, through the above design, enables accurate positioning of local coatings on the product and rapid clamping of fixtures. During use, depending on the coating conditions, this application can use metal or plastic materials, such as stainless steel or titanium alloys, or materials such as ABS or PEEK.

[0035] The foregoing description illustrates and describes preferred embodiments of the present invention. As previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or related technical or knowledge.
