Technical Field

[0001] The present application relates to the technical field of electroplating, and in particular to a plating liquid feeding device for electroplating. Background Art

[0002] At present, electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. The electroplating solution refers to a liquid that can expand the cathode current density range of the metal, improve the appearance of the coating, and increase the anti-oxidation stability of the solution.

[0003] Conventionally, when adding plating solution to a plating material bath, a plating solution feeding device is usually used to directly add the plating solution to the plating material bath.

[0004] The above-mentioned prior art solutions have the following defects: when the existing electroplating liquid feeding device is in use, because the feeding device itself does not have a filtering function, once the electroplating liquid contains foreign particles, it will affect the electroplating effect of the object, thereby increasing the cost. Utility Model Content

[0005] In order to achieve the effect that the electroplating liquid feeding device can filter the electroplating liquid, the present application provides a electroplating liquid feeding device for electroplating.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A plating liquid feeding device for electroplating includes a liquid pool, a feeding pipe and a filtering device, one end of the feeding pipe is fixedly connected to the liquid pool, the filtering device is fixedly connected to the inner wall of the feeding pipe, and the filtering device is used to filter the electrolyte entering the liquid pool through the feeding pipe; the filtering device includes a sleeve and a filter core, the sleeve is fixedly connected to the inner wall of the feeding pipe, the filter core is arranged in the sleeve, and the filter core is fixedly connected to the sleeve.

[0008] By adopting the above scheme, the feeding pipe is fixedly connected to the liquid pool, the electroplating liquid flows into the liquid pool through the feeding pipe, and a filtering device is fixedly connected in the feeding pipe, the filtering device includes a sleeve and a filter element, the sleeve is fixedly connected to the feeding pipe, the filter element is arranged in the sleeve and fixedly connected to the sleeve, when the electroplating liquid enters the feeding pipe, it is first filtered by the filter element, and the electroplating liquid filtered by the filter element flows into the liquid pool, the filter element intercepts impurities in the electroplating liquid, so that the electroplating liquid entering the liquid pool is free of impurities, and through the above arrangement, the effect of the electroplating liquid feeding device being able to filter the electroplating liquid is achieved.

[0009] Furthermore, the filter element includes a filter plate and a filter net, the filter plate is located above the filter net, the filter hole diameter of the filter net is smaller than the filter hole diameter of the filter plate, and the filter plate and the filter net are fixedly connected to the inner wall of the sleeve.

[0010] By adopting the above scheme, the filter element is divided into two parts, the first part is the filter plate, and the second part is the filter net; the aperture of the filter hole on the filter plate is larger than the aperture of the filter hole on the filter net, and the filter plate is placed above the filter net; when the electroplating solution enters the liquid pool through the feeding pipe, it first passes through the filter plate for primary filtration. Since the aperture of the filter plate is large, it can be ensured that the filtrate can filter out larger impurities without affecting the flow rate of the filtrate.
