A copper foil surface treatment machine with self-adaptive tension

Abstract

A self-adaptive tensioning force copper foil surface treatment machine, which relates to the field of copper foil processing, the two inner walls of the pickling tank are sealed and rotated to be provided with clamping shaft seats, and the two outer sides of the pickling tank are fixedly provided with brackets. An arc groove is opened on the top, and a push rod is also rotated on the support plate, and the free end of the push rod is fixedly connected with the first top block; the side of the arc groove away from the push rod is provided with a ratchet mechanism fixed on the bracket; The bracket is also provided with a lifting mechanism, the lifting mechanism is fixedly provided with an elastic piece, and the elastic piece is fixedly connected with a second top block; the outside of the pickling tank is also provided with a folding windshield, and the folding windshield is provided with an alkali water tank. In this technical solution, the submerged roller is set in the form of hanging and clamping, which saves the process of discharging acid, and arc grooves are set to change the position of the tension roller to avoid the submerged roller from hanging and working, and the lifting mechanism is used to control the tension roller The height of the copper foil is set, and elastic parts are set to realize the function of automatic fine-tuning of the tension of the 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
