The pickling process uses chemical solutions to clean the surface of the copper foil, which can effectively remove pollutants such as oil and oxides, but there is a problem that the chemical solution residue is not easy to remove. The water washing process uses an aqueous detergent to clean the copper foil, which has the advantages of simple operation and low environmental pollution, but it is not effective in removing stubborn pollutants. In order to improve the cleaning effect, pickling and water washing are often combined in the prior art, and deep cleaning of the copper foil surface is achieved by the steps of pickling first and then water washing. However, in actual use, it is found that if the pickling tank and the water washing tank are directly connected, the acid may enter the water washing tank during the cleaning process, thereby affecting the cleaning effect of the copper foil in the water washing link.
