Abstract

The invention discloses a processing device based on electrolytic copper foil before slitting, the processing device comprises a supporting mechanism, an angle stripping adjusting mechanism, a washing adjusting mechanism and an adsorption processing mechanism, the supporting mechanism is installed on the outer side of a copper foil outlet of an anode tank, a cathode roller is installed in the anode tank, and the cathode roller is connected with a transmission motor through a coupler; the transmission motor works to drive the cathode roller to rotate in the anode groove, an angle stripping adjusting mechanism is installed on the side face of the supporting mechanism, and a washing adjusting mechanism and an adsorption treatment mechanism are sequentially installed on the top of the supporting mechanism along the copper foil outlet side. The distance and the relative position between the stripping roller and the copper foil can be adjusted, the efficiency and the integrity of stripping the copper foil from the cathode roller are improved, the damage such as tearing to the copper foil in the copper foil stripping process is reduced, the flushing amount can be adjusted according to different stripping speeds, the controllability of the flushing amount is achieved, and the stripping efficiency is improved. Meanwhile, water on the surface of the copper foil adsorbed by the adsorption roller can be fully extruded, and the adsorption effect on the water on the surface of the copper foil is improved.

Description

technical field [0001] The invention belongs to the technical field of copper foil processing, and relates to a processing device based on electrolytic copper foil before slitting. Background technique [0002] Electrolytic copper foil is an important material for copper clad laminate (CCL), printed circuit board (PCB), and lithium-ion battery manufacturing. In the rapid development of today's electronic information industry, electrolytic copper foil is known as the "neural network" of electronic product signal and power transmission and communication. The production of raw foil is based on the principle of electrolysis. The copper sulfate electrolyte is transported into the DC electric field, and the copper ions move to the cathode and precipitate to form a copper foil layer on the surface of the cathode roll. The formed copper foil layer is peeled and rolled to form an electrolytic copper foil. finished product. As an electrodeposited product, electrolytic copper foil ha...

Problems solved by technology

[0003] After the copper foil comes out of the anode tank, because there is a copper sulfate solution on the rough surface of the copper foil, it will be oxidized immediately once it comes into contact with the air. Oxidation, the copper foil stripped from the cathode roll is washed with water, some of the washed copper foil is heated or air-dried, resulting in watermarks on the surface of the copper foil, and some copper foil manufacturers use a scraper to clean the moisture on the surface of the copper foil , causing the surface of the copper foil to be scratched. No matter what method is used in the existing technology, the copper foil after washing will be damaged, which will affect the quality of the copper foil, cause a large scrap rate for the later copper foil slitting, and reduce the after-slitting. The qualified rate of copper foil; at the same time, the process of stripping copper foil from the cathode roll in the prior art is to manually install and fix the position of the stripping roll, and it is impossible to adjust the position and angle of the stripping roll, resulting in the stripping roll after fixed installation. There are problems such as serious peeling damage to the copper foil. In addition, the existing technology cannot control the amount of flushing water according to the speed at which the copper foil is peeled from the cathode roller, resulting in waste of water sources. For copper foils with a fast peeling speed, once the amount of flushing water is insufficient , will cause problems such as incomplete cleaning of the copper sulfate solution on the surface of the copper foil
