Cathode bearing hanger for electroplating

Abstract

The invention provides a cathode bearing hanger for electroplating. The top of a to-be-electroplated plate-shaped product is clamped in a first bearing bend 401 of a row of conductive U-shaped hanging hooks on the upper portion, and the bottom of the to-be-electroplated plate-shaped product is borne in a second bearing bend 402 of a row of conductive U-shaped hanging hooks on the lower portion. Therefore, the plate-shaped product to be electroplated is fixed. In the process, the two ends of the plate-shaped product to be electroplated are shielded by the cathode insulation baffles. And the hanging hooks arranged on the two conductive connecting vertical plates are hung on an external connecting frame and are electrically connected with an external cathode. The insulation paste is arranged on the surfaces of the two conductive connection vertical plates and the conductive connection transverse plates, so that plating layers can be prevented from being formed on the surfaces of the two conductive connection vertical plates and the conductive connection transverse plates in the electroplating process, and waste of electroplating materials and damage to the conductive hanger framework are avoided. The two ends of the to-be-electroplated plate-shaped product are shielded by the cathode insulation baffles, so that thick plating layers can be prevented from being formed at the two ends of the to-be-electroplated plate-shaped product.

Description

Technical Field

[0001] The present invention relates to the field of cathode carrying fixtures, and particularly to a cathode carrying fixture for electroplating. Background Art

[0002] Electroplating is a process of plating a thin layer of other metals or alloys on the surface of certain metals or other conductive objects by using the principle of electrolysis. It is a process of making the surface of metal or other material parts adhere to a metal film by using electrolysis. During electroplating, the coating metal or other insoluble materials are used as anodes, and the workpiece to be plated is used as a cathode. The cations of the coating metal are reduced on the surface of the workpiece to be plated to form a coating. To exclude the interference of other cations and make the coating uniform and firm, a solution containing cations of the coating metal is used as the electroplating solution to keep the concentration of the cations of the coating metal unchanged. The purpose of electroplating is to deposit a metal coating on the substrate to change the surface properties or dimensions of the substrate.

[0003] However, during the electroplating process, fixtures are needed to clamp and fix the products to be plated. Traditional electroplating fixtures, for example, the technical solution protected by the patent with the application number CN202210619171.7 and the invention name of electroplating fixture, will be electroplated with a coating during the electroplating process, wasting electroplating resources.

[0022] Please refer to Figures 1 to 6 simultaneously, the present invention provides a cathode carrier hanger 10 for electroplating. The cathode carrier hanger 10 for electroplating includes: a conductive hanger skeleton 100, two U-shaped insulating connecting plates 200, a plurality of cathode insulating baffles 300, and a plurality of conductive U-shaped hanging hooks 400.

[0023] In this embodiment, the conductive hanger skeleton 100 is made of stainless steel. In another embodiment, the conductive hanger skeleton 100 is made of copper. The conductive hanger skeleton 100 includes two conductive connecting vertical plates 110 and a plurality of conductive connecting horizontal plates 120. Hanging hooks 111 are provided at one ends of the two conductive connecting vertical plates 110. The hanging hooks 111 are used for hanging and connecting to an external cathode for power supply. Insulating glue is provided on the surfaces of the two conductive connecting vertical plates 110 and each conductive connecting horizontal plate 120. Each conductive connecting horizontal plate 120 is arranged in parallel. One end of each conductive connecting horizontal plate 120 is perpendicularly connected to and electrically connected with one conductive connecting vertical plate 110, and the other end of each conductive connecting horizontal plate 120 is perpendicularly connected to and electrically connected with the other conductive connecting vertical plate 110.

[0024] The U-shaped insulating connecting plate 200 is adapted to the conductive connecting vertical plate 110. Each U-shaped insulating connecting plate 200 is correspondingly sleeved on a conductive connecting vertical plate 110 and connected to the conductive connecting vertical plate 110. In this embodiment, the U-shaped insulating connecting plate 200 is screwed to the conductive connecting vertical plate 110. The two cathode insulating baffles 300 are arranged in pairs. The paired cathode insulating baffles 300 are correspondingly arranged on both sides of a conductive connecting horizontal plate 120. One end of each cathode insulating baffle 300 is correspondingly connected to a U-shaped insulating connecting plate 200. A plurality of through holes 301 are formed in the cathode insulating baffle 300. The width of the cathode insulating baffle 300 is greater than the width of the conductive connecting horizontal plate 120. In this embodiment, the U-shaped insulating connecting plate 200 is screwed to the conductive connecting horizontal plate 120. In order to increase the structural strength of the cathode insulating baffle 300, two reinforcing ribs 310 are arranged between the paired cathode insulating baffles 300. The two reinforcing ribs 310 are respectively arranged on both sides of the conductive connecting horizontal plate 120. Further, one of the two reinforcing ribs 310 is integrally formed with one of the paired cathode insulating baffles 300.

[0025] Each conductive U-shaped hanging hook 400 is arranged in an array. A row of conductive U-shaped hanging hooks 400 is provided on both the top conductive connection cross plate 120 and the bottom conductive connection cross plate 120. A row of conductive U-shaped hanging hooks 400 on the top conductive connection cross plate 120 is symmetrically arranged with a row of conductive U-shaped hanging hooks 400 on the bottom conductive connection cross plate 120. Two rows of conductive U-shaped hanging hooks 400 are provided on the middle conductive connection cross plates 120, and the two rows of conductive U-shaped hanging hooks 400 are symmetrically arranged on the middle conductive connection cross plates 120. One end of the conductive U-shaped hanging hook 400 is connected to the conductive connection cross plate 120, and a receiving hook 410 is provided at the other end of the conductive U-shaped hanging hook 400. The receiving hook 410 causes the one end of the conductive U-shaped hanging hook 400 to form a first receiving bend 401 and a second receiving bend 402. Both the first receiving bend 401 and the second receiving bend 402 are used to receive the product to be electroplated. Each conductive U-shaped hanging hook 400 correspondingly passes through a through hole 301 and is inserted between two cathode insulating baffles 300.

[0026] In order to increase the connection stability between the hanging hook 111 and the external connection frame, in one embodiment, the hanging hook 111 and the conductive connection vertical plate 110 are integrally formed to increase the structural stability and structural strength of the conductive hanging tool skeleton 100. Further, in this embodiment, the two conductive connection vertical plates 110 and each conductive connection cross plate 120 are integrally formed to further increase the structural stability and structural strength of the conductive hanging tool skeleton 100. In one embodiment, a V-shaped spring piece 112 is arranged inside the hanging hook 111, and one end of the open end of the V-shaped spring piece 112 is connected to the inner wall of one end of the hanging hook 111. In this embodiment, the V-shaped spring piece 112 and the hanging hook 111 are integrally formed. The V-shaped spring can increase the connection stability between the hanging hook 111 and the external connection frame. Further, in one embodiment, a threaded hole is provided on the hanging hook 111, and a threaded rod 113 is arranged in the threaded hole of the hanging hook 111. The driving head of the threaded rod 113 abuts against the outer wall of the hanging hook 111, and the other end of the threaded rod 113 abuts against the V-shaped spring piece 112. One end of the V-shaped spring piece 112 is squeezed and fixed on the external connection frame through the threaded rod 113. In this way, the connection stability between the hanging hook 111 and the external connection frame is increased.

[0027] During the working process of the above-mentioned cathode carrier fixture 10 for electroplating, the top of the plate-shaped product to be electroplated is clamped in the first receiving bend 401 of the upper row of conductive U-shaped hanging hooks 400, and the bottom of the plate-shaped product to be electroplated is received in the second receiving bend 402 of the lower row of conductive U-shaped hanging hooks 400. Thus, the plate-shaped product to be electroplated is fixed. During this process, both ends of the plate-shaped product to be electroplated are blocked by the cathode insulating baffle 300. The hanging hooks 111 provided on the two conductive connecting vertical plates 110 are hung on the external connecting frame and connected to the external cathode for power supply. Insulating glue is provided on the surfaces of the two conductive connecting vertical plates 110 and each conductive connecting horizontal plate 120, which can prevent the formation of a coating on the surfaces of the two conductive connecting vertical plates 110 and each conductive connecting horizontal plate 120 during electroplating, avoiding waste of electroplating materials and damage to the conductive fixture skeleton 100. Both ends of the plate-shaped product to be electroplated are blocked by the cathode insulating baffle 300, which can prevent the formation of a relatively thick coating at both ends of the plate-shaped product to be electroplated, thus ensuring the uniform thickness of the coating on the plate-shaped product. The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
