Description

Technical Field

[0001] This utility model relates to the field of glass processing technology, specifically to a PVD anti-overflow coating fixture. Background Technology

[0002] With the continuous development of electronic technology products, the components used in these products also need to be optimized accordingly. For example, in the production of 3D glass used in watches, the application of new technologies has created a need for conductive films on both sides. In this case, processes such as coating and laser engraving are generally required to ensure that the 3D glass meets requirements such as a defect-free appearance, specific conductive film patterns, and conductivity on both sides.

[0003] PVD (Polyvinyl Dioxide) is a core surface coating technology widely used in industrial manufacturing, electronics, jewelry, and cutting tools. Its core principle is to convert solid materials into a gaseous phase in a vacuum environment using physical methods such as evaporation, sputtering, and ionization, and then deposit this gaseous substance onto the substrate surface to form a thin film. PVD allows for the customization of film hardness, abrasion resistance, corrosion resistance, and optical properties to meet specific needs. Therefore, PVD is commonly used for coating 3D glass to suit various coating requirements.

[0004] However, existing glass clamping fixtures often have the following drawbacks: 1. The coating fixture has poor applicability and is generally only suitable for RAS vacuum coating machines, not for NSP-1650 sputtering coating machines. Therefore, it greatly limits the coating process of 3D glass and cannot use different coating machines to complete product production or PVD innovation.

[0005] 2. Since most coating fixtures are only suitable for RAS vacuum coating machines, and due to the coating characteristics of the RAS vacuum coating machine itself, 3D glass often has poor coating uniformity and high conductivity resistance after being coated in the RAS vacuum coating machine, resulting in a low yield of 3D glass production.

[0006] 3. After the 3D glass is clamped in the fixture, due to the structural characteristics of 3D glass, the concave surface of the 3D glass is prone to over-plating, which further affects the yield of 3D glass production.

[0007] Therefore, designing a new fixture structure suitable for rotary sputtering coating in sputtering machines has a significant impact on improving the uniformity and yield of 3D glass products. Utility Model Content

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0029] Example 1: Please see the appendix Figure 1-2The PVD anti-overflow plating fixture of this utility model includes a fixture base plate 100 on which multiple annular plating limiting structures 120 are provided, a fixture cover plate 200 mounted on one side of the fixture base plate 100, and multiple anti-overflow plating units 300 corresponding to each annular plating limiting structure 120 and disposed on the fixture cover plate 200. The fixture base plate 100 is used for initial positioning and installation of the product 10 to be coated, improving the uniformity of the coating; the fixture cover plate 200 is used to combine with the fixture base plate 100 to achieve complete positioning and installation of the product 10 to be coated; preferably, the fixture cover plate 200 is mounted on the fixture base plate 100 by screws; the anti-overflow plating units 300 are used to ensure that the first surface of the product 10 to be coated rests against the annular plating limiting structure 120 to prevent over-plating or contamination of the second surface of the product.

[0030] Taking 3D glass as an example, the first side of the product 10 to be coated is the convex side of the glass, and the second side is the concave side of the glass. During the rotary sputtering coating process, the anti-overflow coating unit 300 can press the convex side of the glass against the annular coating limiting structure 120 to prevent the concave side of the glass from being over-coated or contaminated.

[0031] Please refer to the appendix for further details.

Preferably, the coating groove 130 is an arc-shaped coating groove 130 or a sloping coating groove 130, with an open design that is wide at the top and narrow at the bottom, which can further reduce the obstruction of the coating hole 121, thereby further effectively improving the uniformity of the product coating.

[0034] Please refer to the appendix for further details. Figure 4 The fixture base plate 100 also includes a coating forming structure 140, corresponding one-to-one with the annular coating limiting structure 120, and disposed on the side of the fixture base plate body 110 away from the fixture cover plate 200.

Further, the fixture base plate 100 also includes a cover plate limiting boss 160 protruding from the side of the fixture base plate body 110 adjacent to the fixture cover plate 200; the design of the cover plate limiting boss 160 can be used to limit the fixture cover plate 200, thereby improving the stability of the assembly of the fixture base plate 100 and the fixture cover plate 200, and thus effectively improving the product clamping accuracy and ensuring the quality and yield of the product after coating processing.

[0036] The PVD anti-overflow plating fixture in this embodiment further designs and optimizes the structure of the fixture base plate 100 based on Embodiment 1. While ensuring the technical effect of Embodiment 1, it can further effectively improve the overall versatility of the fixture and the uniformity of the product coating, and ensure the quality and yield of the product after coating processing.

[0037] Example 3: Please see the appendix Figure 1-2 The PVD anti-overflow plating fixture of this embodiment is the same as that of Embodiment 1 or 2, including a fixture base plate 100 on which multiple annular plating limiting structures 120 are provided, a fixture cover plate 200 mounted on one side of the fixture base plate 100, and multiple anti-overflow plating units 300 corresponding to each annular plating limiting structure 120 and disposed on the fixture cover plate 200. Further, the fixture base plate 100 includes a fixture base plate body 110 and multiple annular plating limiting structures 120 arranged side-by-side on the fixture base plate body 110; wherein, the annular plating limiting structure 120 includes a plating hole 121 disposed on the fixture base plate body 110, and an arc-shaped limiting groove 122 arranged around the outer periphery of the plating hole 121 and adjacent to the side of the fixture cover plate 200. The main difference is: Furthermore, the anti-overflow plating unit 300 includes an anti-overflow plating component 310 correspondingly disposed on the second surface of the product 10 to be coated, and an adjusting screw 320 connected to the anti-overflow plating component 310 and disposed on the fixture cover plate 200. The anti-overflow plating component is used to press the first surface of the product 10 to be coated against the annular coating limiting structure 120 to prevent overflow plating or contamination of the second surface of the product. Taking 3D glass as an example, the first surface of the product 10 to be coated is the convex surface of the glass, and the second surface is the concave surface of the glass. During the rotary sputtering coating process, the anti-overflow plating component can press the convex surface of the glass against the annular coating limiting structure 120 to prevent overflow plating or contamination of the concave surface of the glass. The adjusting screw 320 is used to drive the anti-overflow plating component 310 to press against the concave surface of the glass. Preferably, the anti-overflow plating component 310 is an anti-overflow plating baffle or anti-overflow plating baffle ring adapted to the product 10 to be coated. The specific design can be selected according to the actual production needs, as long as it can achieve contact with the concave surface of the glass and make the convex surface of the glass tightly adhere to the annular coating limiting structure 120.

[0038] The PVD anti-overflow plating fixture in this embodiment further designs and optimizes the structure of the anti-overflow plating unit 300 based on embodiment 1 or 2. It can further and more effectively prevent overflow plating on the non-coated surface of the product while ensuring the technical effect of embodiment 1 or 2, so as to effectively ensure the overall coating quality and yield of the product.
