Technical Field

[0001] The utility model relates to the field of electroplating devices, in particular to a device for adjusting the liquid level height of a strip line local continuous electroplating solution. Background Art

[0002] Metal strips are used in the production of many switches, electrical appliances, and electronic equipment. In order to achieve the purpose of improving contact, enhancing conductivity, resisting galvanic corrosion, corrosion, wear, and preventing oxidation, it is often necessary to electroplate a layer of other metal or alloy coating on the surface of the metal strip in whole or in part.

[0003] Electroplating refers to the process of depositing a metal or alloy layer on the surface of a conductor such as a metal by electrolytic reaction in a solution with the help of external direct current. During the strip plating process, the liquid level fluctuation caused by the continuous movement of the strip through the plating tank solution, the liquid level fluctuation caused by the impact of the electroplating solution circulating from the storage tank to the plating tank, and the difference in the overflow volume when the strip passes through the overflow port of each plating tank, etc., lead to differences in the liquid level height of each plating tank, which affects the height dimensional accuracy of the local plating layer. In production, film protection is often used to protect the parts that do not need to be plated, leaving the areas that need to be plated exposed for local continuous plating, but this will cause problems such as large equipment investment, high production costs, and a lot of solid waste (protective tape).

[0006] The upper end of the fixing plate is fixedly connected with a driving motor, and the output end of the driving motor passes through the fixing plate and is provided with a lead screw inwardly.

[0007] As a further description of the above technical solution: a threaded block is threadedly connected to the lead screw, and a groove is formed on the inner side of the fixing plate.
