Coating and rolling device for battery production

Abstract

The invention relates to the technical field of battery production equipment, and provides a coating and rolling device for battery production. The coating and rolling device aims to solve the problems that a traditional battery pole piece coating and rolling processing production efficiency is low, meanwhile, a pole piece is exposed in air for a long time, and the controllability of the product quality is extremely poor. The coating and rolling device comprises a device outer shell and a plurality of supporting legs installed at the lower end of the device outer shell; a feeding port and a discharging port are formed in the opposite side walls of the device outer shell respectively, a plurality of rotating rollers used for current collector transmission and tension are installed on the inner wall of the device outer shell, two partition plates are vertically installed in an inner cavity of the device outer shell, the two partition plates sequentially divide the inner cavity of the device outer shell into a coating cavity, a drying cavity and a rolling cavity from left to right in the movement direction of the current collector, a coating mechanism is arranged in the coating cavity, a drying mechanism is arranged in the drying cavity, and a rolling mechanism is arranged in the rolling cavity. The device is particularly suitable for coating and rolling processing of the batterypole piece, and has higher social use value and application prospect.

Description

technical field [0001] The invention relates to the technical field of battery production equipment, in particular to a coating rolling device used for battery production. Background technique [0002] Coating and rolling are two important processes in the production of lithium-ion batteries. In the production process of battery pole pieces, the coating process and the rolling process are set independently of each other, and are carried out on the coating machine and the rolling machine respectively. . The specific operation is to wind up the current collector of the lithium-ion battery after coating on the coating machine, remove the coiled current collector and transport it to the roller press, assemble it on the unwinding mechanism of the roller press and unwind it. Perform roll forming into pole pieces. [0003] This processing method not only has low production efficiency, but also consumes a lot of labor for manual transfer. At the same time, due to the uncontrollabl...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a coating roll press device for battery production, which overcomes the deficiencies of the prior art, has a reasonable design and a compact structure, and aims to solve the problem of traditional battery pole piece coating roll presses. The processing and production efficiency is low, the labor consumption of manual transfer is large, and the pole piece is exposed to the air for a long time. On the one hand, it affects the quality of the current collector after coating, on the other hand, it is also easy to be contaminated with dust, and the controllability of product quality is extremely poor.
