Problems solved by technology

[0004] Therefore, the technical problem to be solved by the embodiment of the present invention is to overcome the technical defects of the vertical electroplating method in the prior art that the amount of clean water is large and the amount of sewage generated is large, so as to provide an electroplating method with a small amount of clean water and a small amount of sewage generated. The cleaning method of the workpiece in

Embodiment 1

[0030] Such as figure 1 As shown, the present embodiment provides a method for cleaning workpieces in vertical electroplating, comprising the steps of:

[0031] Before the micro-etching (the micro-etching is carried out in the micro-etching cylinder 40) after the spray flushing (the spray flushing is carried out in the spray flushing cylinder 20), the workpiece is immersed in water to carry out the first water washing process;

[0032] Before electroplating after microetching (electroplating is carried out in the electroplating tank 90), the workpiece is immersed in water to carry out the second water washing process;

[0033] After electroplating, the workpiece is immersed in water for the third water washing process;

[0034] Wherein, different washing processes use the same clean water source, and the cleaning water flows through the washing tank in the second washing process, a washing tank in the first washing process, a washing tank in the third washing process and a wa...

Embodiment 2

[0051] The workpiece cleaning method in the vertical electroplating of the present embodiment is the deformation on the basis of embodiment 1, and the difference between this implementation and embodiment 1 is:

[0052] The first water washing process has the first water washing tank 31 of the first water washing process, the second water washing tank 32 of the first water washing process, the second water washing process has the first water washing tank 51 of the second water washing process, and the third water washing process The treatment process has a first water washing tank 61 in the third water washing treatment process.

[0053] The first water washing tank 51 of the second water washing process, the second water washing tank 32 of the first water washing process, the first water washing tank 61 of the third water washing process, the first water washing process of the first water washing process The water washing tank 31 communicates with the spraying and washing tan...

Abstract

In the method for cleaning workpieces in electroplating of the present invention, the cleaning water flows sequentially through the washing tank in the second washing process, the washing tank in the first washing process, the washing tank in the third washing process and another washing tank in the first washing process. cylinder. The same clean water source is used in different washing processes, and the flow direction of the water is reasonably arranged according to the cleaning effect to be achieved in each washing process and the degree of "pollution" of the workpiece. The water is reused in each washing process, and the sewage When processing, only the sewage in the first water washing process can be treated. Under the same cleaning effect, the consumption of clean water is reduced, the cost of clean water is reduced, and the water volume of sewage treatment is also correspondingly reduced, and the waste water treatment is reduced. pressure.

Description

technical field [0001] The invention relates to the technical field of electroplating, in particular to a method for cleaning workpieces in vertical electroplating. Background technique [0002] Electroplating is the process of plating a layer of metal or alloy on the surface of some objects by the principle of electrolysis, so as to prevent metal oxidation and corrosion, or improve wear resistance, conductivity, reflectiveness, corrosion resistance, and aesthetic enhancement. . In order to complete the electroplating, the plated parts usually need to be pre-plated with degreasing, micro-etching, pickling and other pre-plating treatments before electroplating. In order to prevent the treatment agent in the pre-plating treatment from polluting the subsequent process, it is necessary to wash and clean the plated parts after degreasing, micro-etching, and pickling to remove the remaining treatment agent on the plated parts in each treatment process. At the same time, after th...
