Description

Technical Field

[0001] The invention relates to the technical field of metal electroplating, in particular to an automated layered electroplating tank for surface treatment of metal parts. Background Art

[0002] Electroplating is a metal processing technology that applies a protective layer on the metal. Electroplating can improve the surface gloss and oxidation resistance of metal parts. During the electroplating process, the product can be placed in the electroplating solution. For products that require layered electroplating, the product can be replaced in different electroplating tanks for electroplating.

[0003] Prior art 1 (publication number CN107620096A, Chinese patent published on January 23, 2018) discloses a process method for layered electroplating, comprising the following steps: (1) acid immersion, water washing and degreasing of the substrate; (2) electroplating the substrate in a solution containing a first metal ion, and then imprinting a pattern on the surface of the substrate; (3) applying an insulating material to a part of the surface of the pattern, and then electroplating the substrate in a solution containing a second metal ion; (4) removing the insulating material and repeating step (3); (5) cleaning the surface of the substrate, washing with water and drying it to complete the layered electroplating. The process method of the present invention is simple to operate, highly efficient and effective. Prior art 2 (publication number CN220132382U, a Chinese patent published on December 5, 2023) discloses a metal product surface electroplating processing equipment. The existing metal product surface electroplating processing equipment usually adopts a clamping method to electroplate the metal product, which results in the need for multiple clamping electroplating, low efficiency, and the inability to collect the debris generated during electroplating. The following scheme is now proposed, which includes a base plate, four support columns are symmetrically fixedly connected to the base plate, and the four support columns are fixedly connected to the same mounting plate, a first motor is fixedly installed on one side of the mounting plate, and an adjustment component is provided on the first motor, a bidirectional motor is fixedly installed on the mounting plate, and a transmission shaft is fixedly connected to the output shafts on both sides of the bidirectional motor, and a filter component is provided on the transmission shaft. This technology can rotate and fully electroplate the metal product, and can collect the debris generated during electroplating, which is convenient for subsequent processing.

When the metal parts move, liquid dripping is easy to pollute the external environment, and it will also reduce the corresponding electroplating treatment efficiency.
