KR-102963617-B1 - Jig for electroplating

Abstract

The present invention relates to a jig capable of performing electroplating while supporting a non-conductive insulating body (1), comprising: a plating section (10) having a electrode plate (11) on the rear edge of the insulating body (1) and a pair of electrode holes (12) penetrating the front surface; a jig body (20) configured to be immersable in an electrolyte (22) contained in a plating tank (21); and one or more jig pin sections (30) made of a conductor that performs a plating operation through a current supplied in a state of being in close contact and supported to the plating section (10) of the insulating body (1) on the jig body (20). Accordingly, the present invention improves the structure of a jig used in electroplating operations, thereby enabling very easy attachment and detachment to an insulating body, which enhances workability and ensures stable support without the risk of detachment. Furthermore, it offers excellent conductivity, eliminating plating deviations to enable uniform product production and high-quality plating with consistent performance. Additionally, by minimizing the area in contact with the plating material, it reduces the defect rate and significantly improves the adhesion rate. Moreover, since the jig can be placed in the plating solution while being held automatically or manually by an operator, it provides the effect of being suitable for use in various working environments.

Description

Jig for electroplating The present invention relates to a jig for electroplating, and more specifically, to an electroplating jig in which the structure of the jig used for electroplating operations is improved so that it can be easily attached to and detached from an insulating body, thereby improving workability and ensuring stable support without the risk of detachment; furthermore, it has excellent conductivity, allowing for the production of uniform products without plating deviation and obtaining high-quality plating with consistent performance; it minimizes the area in contact with the plating material, thereby reducing the defect rate and significantly improving the adhesion rate; and it allows the jig to be placed in the plating solution while being held automatically or manually by an operator, making it suitable for use in various working environments. Typically, electroplating is a coating method that applies a metal film to the surface of a product using the principle of electrodeposition. In this process, the metal product to be plated is connected to the cathode, and the metal to be coated is connected to the anode. Both metals are then immersed in an electrolyte, and an electric power source is applied to deposit a metal film on the product's surface. During electroplating, when the product is immersed in the electrolyte while attached to a jig, it becomes electrically connected to the cathode through the jig. However, if the contact area is small, it is difficult to supply a smooth current, leading to abnormalities in plating thickness and the production of low-quality products, as well as a significant decrease in load-bearing capacity. Conversely, while a large contact area allows for a smooth current supply, the high friction points can cause issues such as scratches. Therefore, the key is to produce high-quality products with a minimal contact area. For example, according to Korean Registered Utility Model No. 234042, “an electroplating jig is disclosed, characterized by being formed with a plating fixing member that is detachably attached to a pair of electrode holes formed penetrating the pair of electrode plates and an insulating body to make the inner and outer plating thicknesses of the pair of electrode plates uniform, and the plating fixing member is characterized by being formed in a V-shape.” As another example, according to Registered Utility Model Publication No. 234043, an “electroplating jig is disclosed, characterized by being formed with a plating fixing member that is detachably attached to a groove formed between the pair of electrode plates to make the inner and outer plating thicknesses of the pair of electrode plates uniform, wherein the plating fixing member is formed in an M-shape, with the central part fitted into the groove and both ends each in close contact with the outer periphery of the insulating body.” However, in any of the aforementioned cases, since the jig has a structure in which it is attached in close contact to the insulating body, that is, a pair of electrode holes of the magnetron ceramic cathode or the outer periphery of the insulating body, due to its shape (V, M), when a large number of insulating bodies collide with each other due to the rotational force of the rotating barrel and strong external pressure is applied to the jig, the jig must exert high support while maintaining a firm state from the insulating body to reduce plating deviation. However, it is difficult to maintain this, causing the jig to detach from the insulating body, resulting in a decrease in plating quality. Consequently, plating defects caused by plating deviation frequently occur, leading to severe variations in product performance and the disadvantage of being unable to produce uniform products.
