Description

Technical Field

[0001] The invention belongs to the technical field of brush plating, and in particular relates to an automated nano brush plating device and method. Background Art

[0002] Brush plating is a widely used technology in surface treatment. It deposits a uniform and dense metal or non-metallic coating on the metal surface through electrochemical reaction, thereby giving the base material various special or modified physical and chemical properties. Usually on this basis, the technical effect of the above special process can be further improved by adding nanomaterials. The traditional brush plating industry mainly adopts manual operation, which has the following problems: 1. There are fluctuations in process consistency. Traditional technology usually sets parameters such as current intensity, and then manually dips the plating solution for brush plating. There are fluctuations in personnel quality between different workers; in addition, even for the same worker, there are inevitable fluctuations in product coating quality consistency due to differences in brush plating habits and brush plating strength. 2. The process is not environmentally friendly. The brush plating process carried out by traditional technology will inevitably produce waste gas and waste liquid. The waste gas will cause human damage to the workers who operate it. The waste liquid is usually not completely collected and recycled, which will affect the factory or the external environment after discharge. 3. The production efficiency is not high. Traditional technology mainly relies on manual operation to brush-plate one or a few products at a time, which inevitably leads to a positive correlation between production capacity and the number of workers, and then a bottleneck in production efficiency. 4. The degree of precision of process parameters is difficult to further improve. The production process adopted by traditional technology often compares the coating layer horizontally after combining a series of process parameters, and selects the best parameter combination, but it is difficult to be the optimal combination. The reason is that there are many factors affecting the brush plating process and they affect each other. Prior art CN110184634B discloses a planar automated brush plating device, which adopts a brush plating device based on a mechanical structure, which can improve some of the above problems, but there is still room for technical improvement in production efficiency, environmental friendliness and precision of process parameters.
