Electro-deposition copper foil post-treatment device

Abstract

The invention discloses an electro-deposition copper foil post-treatment device. The device comprises a mounting table, an electrolytic tank is fixedly arranged on the mounting table, an anode plate is arranged at the bottom of the electrolytic tank, a cathode roller is coupled in the electrolytic tank, a mounting frame is fixedly connected to the mounting table above the cathode roller, a copper foil cleaning mechanism is arranged on the mounting frame, a drying mechanism is arranged on one side of the copper foil cleaning mechanism, and a winding mechanism is arranged on one side of the drying mechanism. According to the electro-deposition copper foil post-treatment device, a copper sulfate solution attached to the surface of the copper foil flows into an anode tank again through a liquid squeezing roller, and recycling of the copper sulfate solution is achieved; and the upper and lower surfaces of the copper foil are cleaned through a plurality of groups of brush water spraying rollers and vacuum adsorption rollers, and are dried through a drying box body, so that the copper sulfate solution attached to the surfaces of the copper foil is thoroughly removed.

Description

technical field [0001] The invention relates to the technical field of copper foil production equipment, in particular to an electrodeposited copper foil post-processing device. Background technique [0002] Electrolytic copper foil is an important material for the manufacture of copper clad laminates, printed circuit boards, and lithium-ion batteries. In the rapid development of today's electronic information industry, electrolytic copper foil is called the "neural network" of electronic product signal and power transmission and communication. [0003] Electrolytic copper foil The electrolytic copper foil deposited on the surface of the cathode roll will adhere to the surface of the copper sulfate solution in the electrolysis area when the cathode roll rotates out of the anode tank. Copper foil with copper sulfate solution attached to the surface must be subjected to subsequent surface treatment within 2-3 days, otherwise severe oxidation will occur on the surface, which w...

AI Technical Summary

Problems solved by technology

Copper foil with copper sulfate solution attached to the surface must be subjected to subsequent surface treatment within 2-3 days, otherwise severe oxidation will occur on the surface, which will cause blackening of the surface of the electrolytic copper foil, which will seriously affect the resistance to dip soldering index and anti-peel strength, and the subsequent surface treatment process is difficult to remove the oxide layer on the surface
