System and method for automatically adding brightening agent into barrel plating liquid

Abstract

The invention discloses a system for automatically adding a brightening agent into a barrel plating liquid. The system is characterized by comprising a brightening agent quantitative input assembly, abrightening agent storage device, a traveling crane, a brightening agent adding assembly and a PLC, the brightening agent quantitative input assembly is used for injecting a brightening agent into the brightening agent storage device, the brightening agent storage device is mounted on the travelling crane, the brightening agent adding assembly is connected with the brightening agent storage device and used for outputting materials in the brightening agent storage device and the PLC is used for controlling the brightening agent to be automatically and quantitatively injected into the brightening agent storage device and the barrel plating solution in a plating tank. The system is convenient to operate, ensures the accuracy of the dosage of each brightening agent, is wide in adding range and easy to disperse, and achieves the effect of manual adding; and meanwhile, the investment cost is greatly reduced, and the ordinary maintenance workload is reduced. In addition, the method providedby the invention is automatically controlled in the whole process, and adding miss and excessive adding are avoided.

Description

technical field [0001] The invention relates to a system and method for automatically adding brightener to barrel plating solution. Background technique [0002] During the production and processing of parts, it is often necessary to electroplate them. It is inconvenient to operate the electroplating process of some small parts alone, so it is generally a process of electroplating a large number of small parts in a rolling container (drum). This process is called barrel plating, and the electroplating solution that is used for barrel plating is exactly said barrel plating solution of the present invention. In the barrel plating process, in order to improve the texture of the appearance of the parts and make the coating smooth, it is often necessary to add a brightener to the barrel plating solution. Existing common methods of adding brightener are: (1) when barrel plating, after each drum product enters the plating tank, a certain amount of brightener is manually measured ...

AI Technical Summary

Problems solved by technology

These above-mentioned methods have the following disadvantages: (1) the effect is the most ideal when manually added, the added area is very large and can be quickly dispersed in the bath, and it can be effective in time when the product entering the bath is very close; The labor intensity is very high, and the error of manual measurement is also large, which is not conducive to the control of high requirements

(2) The above two methods of automatic addition have a common disadvantage. Adding at a fixed point is not conducive to dispersion, and can only be dispersed into the plating solution by circulating filtration; the effect of the brightener cannot be exerted in time for products that are far away from the adding point.

This method of automatic addition is not very suitable in barrel plating, and the cost is high
