Abstract
Description
Technical Field
[0001] This utility model belongs to the field of PVD technology, and in particular relates to a PVD fixture. Background Technology
[0002] Existing PVD fixtures are all made from metal parts. This is mainly because PVD requires high temperatures, must be performed in a vacuum environment, and must not generate impurity gases, as these will affect the color and performance of the PVD product. Using metal parts is an ideal material for PVD fixtures; however, this method limits the shape of the fixture. For complex shapes, metal processing is costly and can be complex and difficult to execute.
[0003] To reduce the processing difficulty of complex-shaped PVD jigs, some PVD jigs are made of hard and soft plastic materials. Since hard and soft plastic materials can be molded using injection molding and hot pressing molds, the jigs made by the mold-making method are efficient, low-cost, and come in various forms, making it possible to make products with complex structures.
[0004] However, the PVD process involves relatively high temperatures, typically between 120-200℃. The resins and solvents inherent in both hard and soft plastic materials can cause gas evaporation from the exposed fixture at high temperatures, affecting the stability of the PVD color and performance. Furthermore, the PVD process requires evacuating the furnace beforehand and then filling it with the necessary reaction gases (such as nitrogen, argon, and oxygen) to react with the target material and achieve the desired color and properties. The presence of other impurities can negatively impact the color and adhesion of the product during the PVD process. Utility Model Content
[0005] This utility model provides a PVD fixture, which aims to solve at least one of the technical problems mentioned in the background art.
[0006] This utility model embodiment is implemented as follows: a PVD fixture includes a fixture body and a metal plating layer formed on the surface of the fixture body, wherein the metal plating layer completely covers the fixture body.
[0007] The fixture body is made of plastic or soft rubber, and the metal coating is a single metal coating or a composite metal coating composed of multiple metal coatings.
[0008] Preferably, the composite metal coating comprises a conductive layer, an intermediate layer, and a heat-resistant surface layer sequentially deposited on the surface of the fixture body.
[0009] Preferably, the thickness of the surface heat-resistant layer is greater than the thickness of the conductive layer, and the thickness of the surface heat-resistant layer is less than the thickness of the intermediate layer.
[0010] Preferably, the thickness of the surface heat-resistant layer is 5-15 μm, the thickness of the intermediate layer is 20-50 μm, and the thickness of the conductive layer is 0.3-0.5 μm.
[0011] Preferably, the intermediate layer is a copper layer, and the surface heat-resistant layer is a nickel layer, a chromium layer, or a titanium layer.
[0012] Preferably, the single metal coating is a nickel layer, a chromium layer, or a titanium layer.
[0013] Preferably, the thickness of the single metal coating is 3-8 μm.
[0014] Preferably, at least one surface of the fixture body has a microporous structure, and the metal plating is at least partially embedded in the microporous structure.
[0015] Preferably, the microporous structure is an array of micropores formed on the surface of the fixture body.
[0016] Preferably, the pore size in the microporous structure gradually increases from the center of the surface of the fixture body towards the edge.
[0017] The beneficial effects achieved by this invention are as follows: By using plastic or soft rubber materials to make the PVD fixture body, the processing difficulty of complex-shaped PVD fixtures can be reduced, resulting in low cost. Then, a metal coating is deposited on the surface of the PVD fixture body, completely encapsulating it. During the high-temperature PVD process, the surface metal coating can prevent the volatilization of gases or other substances generated by the plastic or soft rubber material inside the fixture during heating, thereby avoiding any impact on the PVD color and adhesion.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0022] Example 1
[0023] Please see Figure 1 The image shows a PVD fixture in Embodiment 1 of this utility model, including a fixture body 10 and a metal plating layer 20 formed on the surface of the fixture body 10. In specific implementation, the metal plating layer 20 can be formed on the surface of the fixture body 10 by sputtering or electroplating. The metal plating layer 20 completely covers the fixture body 10, preventing the fixture body 10 from being exposed.
[0024] In practical implementation, the fixture body 10 is made of plastic or soft rubber. Plastic materials can be, but are not limited to, PC, ABS, PMMA, etc., while soft rubber materials can be, but are not limited to, TPU, TPE, silicone, rubber, etc. Hard plastic fixtures, made of plastic, have a certain strength and can be used for support and shielding. Soft rubber fixtures, being elastomers, can be used for localized sealing. The lower surface hardness of plastic fixtures reduces the likelihood of scratches on the product surface, significantly improving product yield.
[0025] The metal coating 20 is a single-metal coating, preferably a nickel, chromium, or titanium layer. The thickness of the single-metal coating is 3-8 μm, preferably 5 μm, 6 μm, or 7 μm. The specific thickness can be comprehensively considered based on factors such as the thickness of the substrate and the heating temperature, and is not specifically limited here. In some preferred embodiments of this example, a layer of metal material such as chromium or titanium is deposited on the surface of the plastic or soft rubber using a low-temperature PVD (below 100°C) magnetron sputtering process. The metal coating completely covers the surface of the product, thereby achieving the purpose of sealing the pores. The surface metal coating will not change or peel off during the high-temperature PVD process. Moreover, the metal electroplating layer on the surface of the plastic or soft rubber can also prevent the volatilization of internal gases after the plastic or soft rubber is heated, thus avoiding affecting the PVD color and adhesion of the metal parts.
[0026] Example 2
[0027] Please see Figures 2-3 The image shows a PVD fixture in Embodiment 2 of this utility model. The difference between the PVD fixture in this embodiment and the PVD fixture in Embodiment 1 is that:
[0028] The metal plating layer 20 is a composite metal plating layer composed of multiple metal plating layers. Specifically, in some preferred embodiments of this example, the composite metal plating layer 20 includes a conductive layer 21, an intermediate layer 22, and a surface heat-resistant layer 23 sequentially plated on the surface of the fixture body 10. Specifically, the intermediate layer 22 is a copper layer, and the surface heat-resistant layer 23 is a nickel layer, a chromium layer, or a titanium layer. The thickness of the surface heat-resistant layer 23 is greater than the thickness of the conductive layer 21, and the thickness of the surface heat-resistant layer 23 is less than the thickness of the intermediate layer 22. Specifically, as some preferred embodiments, the thickness of the surface heat-resistant layer 23 is preferably 5-15 μm, for example, preferably 8 μm, 10 μm, or 12 μm; the thickness of the intermediate layer 22 is preferably 20-50 μm, for example, preferably 25 μm, 35 μm, or 40 μm; and the thickness of the conductive layer 21 is preferably 0.3-0.5 μm, for example, preferably 0.35 μm, 0.4 μm, or 0.45 μm.
[0029] In this embodiment, the conductive layer 21, the intermediate layer 22, and the surface heat-resistant layer 23 are sequentially formed on the surface of the fixture body 10 by electroplating. The bottom conductive layer 21 improves the overall electroplating effect. The intermediate layer 22 is made of copper, which has excellent metallic properties and can ensure the performance of the entire metal coating 20, preventing it from peeling or deforming due to thermal expansion and contraction during the PVD process. The surface heat-resistant layer 23 is made of nickel, chromium, or titanium, which can improve the heat resistance of the entire metal coating 20 and make it suitable for more PVD scenarios.
[0030] Similarly, in this embodiment, a composite metal coating is sequentially deposited onto the surface of plastic or soft rubber by water plating. The composite metal coating completely covers the surface of the product, thereby achieving the purpose of sealing the holes. The surface composite metal coating will not change or fall off during the high-temperature PVD process. Moreover, the composite metal coating on the surface of plastic or soft rubber can also prevent the gas generated inside the plastic or soft rubber from evaporating after heating, thus avoiding affecting the color and adhesion of the metal parts in PVD.
[0031] Example 3
[0032] This utility model embodiment three also provides a PVD fixture body. The difference between the PVD fixture in this embodiment and the PVD fixture in embodiment one is that:
[0033] At least one surface of the fixture body 10 is provided with a microporous structure, and at least part of the metal plating layer 20 is embedded in the microporous structure. It should be noted that since the fixture body 10 is made of plastic or soft rubber, while the metal plating layer 20 is made of metal, their thermal conductivity is completely different. During the high-temperature PVD process, internal tension can easily occur due to thermal expansion and contraction, leading to deformation, detachment, or internal delamination of the fixture body 10 and the metal plating layer 20. Therefore, this embodiment further provides a microporous structure on the surface of the fixture body 10. Specifically, the microporous structure can be a plurality of interconnected or non-interconnected micropores. Thus, when the metal plating layer 20 is formed, at least part of the metal plating layer 20 is embedded in the microporous structure, thereby increasing the adhesion of the metal plating layer 20 to the plastic or soft rubber surface and preventing deformation or detachment.
[0034] In some preferred embodiments of this example, microporous structures are preferably formed on each surface of the fixture body 10. Since the fixture body 10 is made of plastic or soft rubber, the microporous structure can be easily formed on the surface of the fixture body 10 by microporous molding technology during hot pressing or injection molding.
[0035] As an example and not a limitation, in some alternative embodiments, the microporous structure is specifically an array of micropores formed on the surface of the fixture body 10, that is, a plurality of micropores are arranged in an array.
[0036] Furthermore, and more preferably, the pore size in the microporous structure gradually increases from the center of the surface of the fixture body 10 towards the edge, that is, the pore size is larger closer to the surface edge. Since heat is transferred from the outside to the inside in a high-temperature environment, the material closer to the outside is more affected. By making the pore size closer to the surface edge larger, the adhesion strength of the external material can be increased.
[0037] It should be noted that the above embodiments and their technical solutions can be combined arbitrarily without conflict, and the new technical solutions obtained by the combination still fall within the protection scope of this utility model. Furthermore, the above embodiments are largely the same in terms of implementation principle; for parts not described in Embodiments 2 and 3, please refer to the corresponding content in Embodiment 1.
[0038] In summary, this is a utility model embodiment. By using plastic or soft rubber material to manufacture the PVD fixture body 10, the processing difficulty of complex-shaped PVD fixtures can be reduced, resulting in low cost. Then, a metal plating layer 20 is deposited on the surface of the PVD fixture body 10, completely covering it. During the high-temperature PVD process, the surface metal plating layer 20 can prevent the volatilization of gases or other substances generated by the plastic or soft rubber material inside the fixture during heating, thereby avoiding any impact on the PVD color and adhesion.
