Self-adaptive tension copper foil surface treatment machine

Abstract

The invention discloses a self-adaptive tension copper foil surface treatment machine, and relates to the field of copper foil processing. The self-adaptive tension copper foil surface treatment machine is characterized in that clamping shaft seats are rotatably arranged on two inner side walls of a pickling tank in a sealing mode, brackets are fixedly arranged on two outer sides of the pickling tank, arc grooves are formed in the brackets, a push rod is rotatably arranged on a support plate, and a free end of the push rod is fixedly connected with a first top block; a ratchet mechanism fixed to the support is arranged on the side, away from the push rod, of the arc groove; a lifting mechanism is further arranged on each bracket, an elastic piece is fixedly arranged on the lifting mechanism, and a second ejector block is fixedly connected to the elastic piece; a folding fan cover is further arranged on the outer side of the pickling tank, and an alkaline water tank is arranged in the folding fan cover. According to the technical scheme, a submerged roller is arranged to be in a hanging and clamping mode, the process of discharging acid liquor is omitted, the arc grooves are formed to change the position of a tensioning roller to avoid hanging work of the submerged roller, the lifting mechanism is used for controlling the height of the tensioning roller, and the elastic piece is arranged to achieve the effect of automatically and finely adjusting the tension of copper foil.

Description

technical field [0001] The invention relates to the field of copper foil processing, in particular to a copper foil surface treatment machine with self-adaptive tension. Background technique [0002] Copper foil is widely used in the manufacture of lithium-ion batteries and printed circuit boards, and the preparation methods of copper foil are becoming more and more mature. Electrolytic copper foil is one of the main ways to produce copper foil. In the post-treatment process of electrolytic copper foil, copper foil needs to be pickled, galvanized, and passivated to improve the surface quality of copper foil. [0003] The pickling process is to let the copper foil deoxidize through the pickling tank. There are liquid rollers in the pickling tank and tension rollers above the pickling tank. The rotation of each roller drives the copper foil to run. The existing copper foil surface treatment machines have the following problems: First, because the liquid roller needs power inp...

AI Technical Summary

Problems solved by technology

The existing copper foil surface treatment machines have the following problems: First, because the liquid roller needs power input, the roller shaft of the liquid roller needs to extend out of the pickling tank to connect the power equipment, and the liquid roller needs to be removed from the tank when it is replaced. The shaft hole on the side is drawn out, so that all the acid in the tank needs to be discharged, which increases the replacement time; second, if the liquid roll is changed to a hanging type, then when the liquid roll is hoisted or lowered, the pickling tank The upper tension pulley will hinder this process, so the tension pulley above the pickling tank must be removed first when the copper foil surface treatment machine is lifting the liquid roll, and the tension pulley needs to be reinstalled after lifting, which makes The hanging operation is very cumbersome; third, the top of the pickling tank is exposed to the air, and the sulfuric acid volatilizes in the air to form acid mist. Even if the copper foil has been pressed and sprayed to remove the acid after pickling, the acid mist will still contact to the copper foil, resulting in the formation of black spots on the surface of the copper foil after long-term contact with the acid mist
