Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating technology, and in particular to a coating tooling. Background Technology
[0002] Vacuum coating technology is one of the physical vapor deposition methods. Its principle is to sublimate or sputter the film material by means of thermal evaporation or ion beam bombardment, and then project it onto the substrate in a vacuum environment, eventually depositing a solid thin film on the substrate surface. When vacuum ion plating equipment is used for coating, it is generally necessary to fix the workpiece with tooling or other fixing devices to perform coating treatment on its surface.
[0003] Existing coating fixtures often clamp the workpiece using a bottom edge. Due to limitations in the processing method, it is difficult to reduce the thickness of the edge, resulting in a large transition shadow during coating and reducing the effective coating area. Utility Model Content
[0004] To overcome the shortcomings of the existing technology, this utility model provides a coating fixture, the technical solution of which is as follows:
[0005] A coating fixture includes a substrate and a sheet. The substrate includes a support wall and a receiving groove. The receiving groove is located at the center of the substrate and extends through the upper and lower surfaces of the substrate. The edge of the receiving groove forms the support wall. The sheet is installed on the lower part of the support wall and surrounds the receiving groove, extending into the receiving groove.
[0006] Furthermore, the sheet is detachably mounted on the lower part of the support wall.
[0007] Furthermore, the sheet is an aluminum plate.
[0008] Furthermore, the bottom of the support wall is recessed inward to form an installation space, the upper surface of the installation space is the installation surface, and the sheet is fixed to the installation surface.
[0009] Furthermore, the coating fixture also includes an installation strip, which is installed in the installation space and presses against the sheet to fix it in place.
[0010] Furthermore, the thickness of the sheet is less than 0.1 mm.
[0011] Furthermore, the substrate is rectangular, and the receiving groove is rectangular.
[0012] Furthermore, the number of the thin sheets is four, and the four thin sheets are installed around the receiving groove, with the four thin sheets connected end to end.
[0013] Furthermore, the upper surface of the support wall extends outward to form a tray.
[0014] Furthermore, the four corners of the tray protrude downwards to form positioning parts.
[0015] The advantages of this invention are: by forming a retaining edge with the thin sheet, the area of the transition shadow caused by the retaining edge during coating is reduced, the effective area of the film layer is increased, and the coating quality is improved. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / as well" as used herein includes any and all combinations of one or more of the associated listed items.
[0022] A coating fixture includes a substrate 1, which includes a support wall 11 and a receiving groove 12. The receiving groove 12 is disposed in the middle of the substrate 1 and penetrates the upper and lower surfaces of the substrate 1. The edge of the receiving groove 12 forms the support wall 11. Specifically, in this embodiment, the substrate 1 is rectangular and the receiving groove 12 is rectangular.
[0023] The upper surface of the support wall 11 extends outward to form a tray 111 for picking up the tooling. The four corners of the tray 111 protrude downward to form positioning parts 112, which are used to constrain the tooling on the worktable.
[0024] The receiving groove 12 includes an installation space 121, which is formed by the bottom of the support wall 11 recessed outward, and the upper surface of the installation space 121 is the installation surface 113.
[0025] The sheet 3 and the mounting strip 4 are aluminum plates. Specifically, in this embodiment, the thickness of the sheet 3 is less than 0.1 mm, and the number of sheets 3 is four. The four sheets 3 are installed on the mounting surface 113, the four sheets 3 are connected end to end, and the four sheets 3 extend into the receiving groove 12 to form a retaining edge that supports the coated part. The mounting strip 4 is installed in the mounting space 121 and presses against the sheet 3 to fix it.
[0026] The working principle of the coating fixture of this utility model is as follows:
[0027] The film formation method of the coating is vapor phase deposition. During the film formation process, the film molecules will move along a certain direction. Due to the processing method of the tooling, it is difficult to reduce the thickness of the baffle on the support wall 11, which affects the movement of film molecules and causes a large transition shadow. By forming a baffle with a thinner sheet 3, the area of the transition shadow can be effectively reduced, the effective area of the film can be increased, and the coating quality can be improved.
[0028] The advantages of this invention are: by forming a retaining edge with a thin sheet 3, the area of the transition shadow caused by the retaining edge during coating is reduced, the effective area of the film layer is increased, and the coating quality is improved.
[0029] The above embodiments only illustrate one implementation of the present utility model, and should not be construed as limiting the scope of the utility model patent. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of the present utility model, and all of these fall within the protection scope of the present utility model.
