Description

Technical Field

[0001] The utility model relates to a coating device, in particular to an adjustable crystal coating fixture. Background Art

[0002] In the production process of the coating field, it is often necessary to encapsulate and protect the objects to be plated before plating. However, due to the different sizes of the objects to be plated, the fixtures usually used for packaging need to be customized one by one, which greatly increases the cost of coating. In order to reduce costs, for small batch production, methods such as tape wrapping are usually used to encapsulate and protect the objects to be plated, and the mask patch is fixed to the surface of the object to be plated by tape pasting to customize the film layer of the required size for plating. However, this packaging method is usually time-consuming and inefficient, and has poor flexibility, and cannot meet the production requirements of large quantities or urgent orders. At the same time, for some more fragile objects to be plated, this type of tape-wrapped packaging method may damage the objects to be plated, such as cracking, surface delamination, etc. In addition, this method may cause the plated film layer to deviate from the set position due to the crooked tape or patch, or the patch may be lifted due to the tape not being firmly pasted, causing the size and style of the plated film layer to deviate from the original design. Therefore, it is necessary to design a fixture that can adapt to the size of the object to be plated within a certain range, while reducing costs and improving the accuracy, efficiency, flexibility and practicality of the coating package. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide an adjustable crystal coating fixture to make the packaging before coating more efficient, accurate, flexible and convenient.

[0004] The utility model adopts the following technical solutions to solve the above technical problems:

[0005] An adjustable crystal coating fixture comprises a fixture body with multiple rows of inner holes, a retractable soft pad block or spring, a retractable soft pad sheet, a wedge block and a mask patch; the characteristics are as follows: the retractable soft pad block or spring and the wedge block are placed in the inner hole of the fixture body, wherein the retractable soft pad block or spring is placed under the wedge block to elastically support the crystal that needs to be coated with a film layer; the retractable soft pad sheet fits with the inner hole wall of the fixture body to elastically fix the crystal that needs to be coated with a film layer; the mask patch is fixed above the inner hole opening of the fixture body by screws, and is tightly fitted with the fixture body surface on the inner hole opening side and the coating surface of the crystal; the mask patch is positioned by four L-shaped angles on the inner hole opening side surface of the fixture body to ensure that the coated film layer is at a preset position on the crystal coating surface.

[0006] The clamp body is made of non-magnetic or demagnetized material with good thermal conductivity, and can be metal such as copper, aluminum or stainless steel.

[0007] The sizes of the fixture body and the multiple rows of inner holes of the fixture body can be flexibly designed according to the size of the crystal to be plated.

[0008] The crystals include a series of crystals including acousto-optic crystals, electro-optic crystals and the like.

[0009] The retractable cushion block and the retractable cushion sheet may be made of silicone or sponge, and the spring may be made of stainless steel.

[0010] The wedge angle block can complement the wedge angle of the crystal with a wedge angle, and the material of the wedge angle block is quartz or glass.

[0011] The mask patch may be 0.05-0.5 mm thick and may be made of non-magnetic materials such as ceramic, aluminum, stainless steel, and copper.

[0012] The advantage of the utility model is that through the coordinated cooperation of the retractable soft pad or spring placed in the inner hole of the coating fixture, the retractable soft pad and the wedge block, the crystals of various sizes within the design range can be well elastically supported and fixed, and the crystal coating surface can always be kept flush with the inner hole side surface of the fixture body. At the same time, the mask patch is locked and positioned with screws and four L-shaped angles respectively, which can ensure that the mask patch can fit tightly with the inner hole side surface of the fixture body and the coating surface of the crystal, and ensure that the plated film layer is at the preset position of the crystal coating surface. Therefore, the adjustable crystal coating fixture can make the packaging before coating efficient, accurate, flexible and convenient. BRIEF DESCRIPTION OF THE DRAWINGS
