Description

TECHNICAL FIELD

[0001] The utility model relates to copper foil surface processing technical field, especially in a kind of on-line polishing device of reducing copper foil roughness. BACKGROUND

[0002] Cathode roller is the core equipment of producing electrolytic copper foil, since electrolytic copper foil is deposited on the surface of cathode roller, and is the mapping of the surface structure of cathode roller, therefore the surface state of cathode roller directly determines the surface state of copper foil.The more uniform the surface of cathode roller is, the more delicate, the more uniform the surface of copper foil produced is;On the contrary, the rougher the surface of cathode roller is, the more uneven the surface of copper foil is.In addition, the surface state of cathode roller also influences the grain structure of copper foil, in the process of depositing to cathode roller, the different roughness of cathode roller surface will first affect the size of cathode surface area, and then affect the current density of electrolysis process, specifically in the size, shape and distribution of copper foil grain, ultimately affect the tensile strength and elongation of copper foil.

[0003] In the production process of electrolytic copper foil, due to long-term immersion in acidic environment, the surface of cathode roller is subjected to electrochemical corrosion, and then the quality of copper foil is affected, so the cathode roller must be polished after being used for a period of time, and the oxide layer produced by corrosion on the surface of cathode roller and the impurities attached to the surface of cathode roller are removed together, and the working state of the smooth surface of cathode roller is restored.Offline polishing and on-line polishing are usually used, in order to reduce the number of shutdowns, if there is no major scratch or burn on the cathode roller, the on-line polishing method is generally selected to remove the abnormal surface of the cathode roller.On-line polishing is divided into dry polishing and wet polishing, the main difference between them is whether water is used for polishing.Wet polishing helps to reduce the roughness of cathode roller, while dry polishing increases the roughness of cathode roller.The traditional cathode polishing process is wet polishing followed by dry polishing, which can effectively remove the oxide layer and impurities on the surface of cathode roller, but cannot reduce the roughness of cathode roller, which is not conducive to improving the tensile strength and elongation of copper foil.Therefore, an on-line polishing device for reducing the roughness of copper foil is provided.
