Technical Field
[0001] This utility model relates to the field of copper foil surface treatment technology, and in particular to a surface treatment device suitable for low-roughness copper foil. Background Technology
[0002] Electrolytic copper foil is one of the basic materials for manufacturing copper-clad laminates and printed circuit boards. It is widely used in electronic products. With the development trend of electronic products being lighter, thinner, shorter, and smaller, the demand for ultra-thin electrolytic copper foil is increasing. The domestic production capacity of electrolytic copper foil with a thickness of 18μm and below is expanding year by year. Copper foil needs to be treated with anti-oxidation during the production process.
[0003] Chinese Patent Publication No. CN218026337U discloses a novel surface treatment device for lithium-ion battery copper foil, including an anti-oxidation liquid tank. Inside the anti-oxidation liquid tank, a first guide roller, a second guide roller, a third guide roller, and a fourth guide roller are rotatably connected via bearings. A fixing frame is fixedly connected to the upper end of the anti-oxidation liquid tank, and an air outlet seat is fixedly connected to the inner wall of the fixing frame. An air outlet nozzle is fixedly connected to the inner side of the air outlet seat. A hot air blower is installed on one side of the anti-oxidation liquid tank, and the outlet of the hot air blower is connected to the air outlet seat via an air duct. This novel surface treatment device for lithium-ion battery copper foil, by configuring the first, second, third, and fourth guide rollers to work together, can guide and transport the copper foil during surface treatment, and significantly increase the contact time between the copper foil and the anti-oxidation liquid, thereby improving the anti-oxidation effect of the copper foil.

This makes it extremely inconvenient to place copper foil, and the operation needs to be carried out inside the anti-oxidation liquid tank, which greatly increases the workload of the staff.

The return pipe 29 is fixedly inserted through the right side wall of the anti-oxidation liquid tank 1.
[0037] Working Principle: This utility model discloses a surface treatment device suitable for low-roughness copper foil. During use, anti-oxidation solution is first poured into the anti-oxidation solution tank 1. Then, the copper foil passes through the top of the two guide rollers 4 and the bottom of the two pressing rollers 6. Subsequently, the first motor 18 and the second motor 23 are activated externally. The second motor 23 drives the second blade 24 to rotate, generating a rearward airflow. The first motor 18 drives the worm gear 14 to rotate via the rotating rod 16. The worm gear 14 drives the lead screw 11 to rotate via the worm 15. The lead screw 11 rotates within the screw hole 10. Under the action of the thread, the fixing frame 9 moves downward relative to the lead screw 11, causing the mounting plate 5 to move downward. The mounting plate 5 moves the pressing roller 6 downwards, which in turn moves the copper foil downwards, pressing and immersing it in the anti-oxidation solution. Then, the copper foil is pulled to the right, moving in the water. At the same time, the guide roller 4 and the pressing roller 6 roll, and the pressing roller 6 drives the first blade 8 to rotate. When the first blade 8 rotates, it drives the internal anti-oxidation solution to flow, so that the anti-oxidation solution can fully contact the copper foil. The copper foil removed from the anti-oxidation solution tank 1 is dried by the airflow generated by the rotation of the second blade 24. The water blown off the copper foil enters the liquid collection hood 26, and the liquid flows back to the anti-oxidation solution tank 1 through the return pipe 29, avoiding waste of anti-oxidation solution and saving resources.
[0038] This device allows for easy operation by adjusting the height of the mounting plate 5 and the pressing roller 6. When copper foil is placed inside the anti-oxidation liquid tank 1, the height of the mounting plate 5 and the pressing roller 6 only needs to be lowered. The mounting plate 5 then presses the copper foil and immerses it in the anti-oxidation liquid. This greatly reduces the workload of the workers.
