Cathode and anode winding machine for lithium battery production

Abstract

The invention relates to a cathode and anode winding machine for lithium battery production, comprising a winding machine body additionally provided with at least one guide mechanism; each guide mechanism comprises a positioning base, an adjusting arm, a guide roller, a positioning roller carrier, a tension sensor, an angle sensor and a control circuit, the positioning base is mounted on the winding machine body through a slide rail, the tail and front ends of the adjusting arm are hinged to the positioning base and the positioning roller carrier respectively through ratchet gear mechanisms, the positioning roller carrier includes a lifting adjusting mechanism and two bearers, the two bearers are distributed symmetrically about an electrode conveying surface of the winding machine body, the bearers are connected through the lifting adjusting mechanism, and the guide roller is embedded in the two bearers. On one hand, electrode winding direction and winding tension can be adjusted automatically; on the other hand, it is possible to clear structures or contaminants such as burs on the surface and side of the electrodes, which may affect the properties of a battery.

Description

technical field [0001] The invention relates to an electrode winding device, in particular to a positive and negative stage winding machine for lithium battery production. Background technique [0002] In the production process of lithium batteries, both positive and negative pole pieces for lithium batteries need to be wound and processed by special winding equipment to meet the needs of use, but in actual use, it is found that the currently used pole piece winding equipment Although it can meet the needs of use to a certain extent, and can ensure the quality of the pole piece winding, but at the same time, there are large deficiencies in the orientation of the pole piece and the ability to adjust the surface tension of the pole piece during winding. Some pollution and quality defects are cleaned up, which causes the current electrode winding operation to have major disadvantages, which is not conducive to the improvement and stability of lithium battery quality. Therefore,...

[0002] In the production process of lithium batteries, both positive and negative pole pieces for lithium batteries need to be wound and processed by special winding equipment to meet the needs of use, but in actual use, it is found that the currently used pole piece winding equipment Although it can meet the needs of use to a certain extent, and can ensure the quality of the pole piece winding, but at the same time, there are large deficiencies in the orientation of the pole piece and the ability to adjust the surface tension of the pole piece during winding. Some pollution and quality defects are cleaned up, which causes the current electrode winding operation to have major disadvantages, which is not conducive to the improvement and stability of lithium battery quality. Therefore, it is urgent to develop a new type of lithium battery electrode for this phenomenon. Winding equipment to meet the needs of actual use
