Description

Technical Field

[0001] The utility model relates to the technical field of surface engineering, in particular to a shielding device for PVD coating. Background Art

[0002] PVD coating is an advanced process for preparing thin films on the surface of materials. It is used in the fields of electronics, optics and mechanics. It aims to improve the performance of the material surface, increase hardness and wear resistance, give a decorative appearance and enhance corrosion resistance. However, the entire surface of the material is not coated. During the coating process, unnecessary parts may be mistakenly plated, affecting the final effect. It is necessary to selectively block designated areas of the workpiece to prevent these areas from being coated with a film layer, so as to achieve a specific coating pattern, meet different functional requirements and ensure product appearance design requirements. At this time, a coating shielding device is needed.

[0003] The existing shielding devices on the market are mainly composed of a frame, a shielding plate and an adjustment mechanism. The effect of shielding a specified area is achieved by adjusting the position and angle of the shielding plate. However, when working, for some workpieces with complex curves, irregular shapes and variable sizes, the shape of a single shielding plate is limited, and its adaptability is still not ideal. It cannot fit the surface to avoid the position around the coating point, causing the coating to be mistakenly plated on other parts. The manual adjustment process of personnel is relatively cumbersome, and it is difficult to quickly and accurately achieve a shielding effect that fully meets the requirements, resulting in affected coating yield. The shielding material will age and deform in an extreme coating environment with high temperature for a long time, which will reduce the accuracy of the shielding and require more frequent replacement and maintenance, increasing the cost of use. Therefore, it is necessary to improve the device to solve the problems of poor shielding effect during use, resulting in poor coating quality, insufficient adaptability and working environment that shortens the service life, and insufficient stability of the operation process to meet the needs of users.
