Rolling processing device of pole pieces for processing of lithium ion battery

Abstract

The invention provides a rolling processing device of pole pieces for processing of a lithium ion battery, and relates to the technical field of rolling devices. The rolling processing device comprises a base, wherein a housing is fixedly mounted at the top of the base; the top of the housing is communicated with a feed hopper; a purification structure is fixedly mounted in the housing; and rolling structures are fixedly mounted on the two sides of the housing at the top of the base, and comprise discharge ports. According to the rolling processing device, the pole pieces of the lithium ion battery are effectively divided by allowing limiting rods to enter feeding pipelines, so that overlapped rolling of the pole pieces of the battery is avoided in a rolling process; rolling forces of allparts of the pole pieces of the lithium ion battery are uniform; and the compaction degree of the interior of the pole pieces of the lithium ion battery is raised. Air cushions are arranged, the volume of the air cushions is increased, the pole pieces of the lithium ion battery are extruded, and rolling forces are adjusted, so that the pole pieces of the lithium ion battery are subjected to appropriate force rolling; and rolling effects of the pole pieces of the lithium ion battery are improved.

Description

technical field [0001] The invention relates to the technical field of rolling devices, in particular to a rolling processing device for pole pieces used for processing lithium-ion batteries. Background technique [0002] Lithium-ion battery is a kind of rechargeable battery. It mainly relies on lithium ions to move between the positive and negative electrodes. Lithium-based batteries are divided into lithium batteries and lithium-ion batteries. Cell phones and laptops use lithium-ion batteries. Usually people Commonly known as lithium batteries. [0003] In the process of lithium battery production and processing, the rolling of lithium-ion battery pole pieces is particularly important. There are many types of lithium-ion battery pole piece rolling devices in the prior art, but in the process of rolling lithium-ion battery pole pieces Among them, because there is no limit structure, the same lithium-ion battery pole piece has been rolled many times, so that the rolling deg...

[0003] In the process of lithium battery production and processing, the rolling of lithium-ion battery pole pieces is particularly important. There are many types of lithium-ion battery pole piece rolling devices in the prior art, but in the process of rolling lithium-ion battery pole pieces Among them, because there is no limit structure, the same lithium-ion battery pole piece has been rolled many times, so that the rolling degree of each lithium-ion battery pole piece is different, resulting in unevenness of the lithium-ion battery pole piece. At the same time, in the traditional rolling device, the position of the squeeze roller is fixed, and there is no structure to control the pressure of the roller, which leads to the unsatisfactory rolling effect of the lithium-ion battery pole piece.
