A positive and negative electrode winding machine for lithium battery production

Abstract

The invention relates to a positive and negative electrode winding machine for lithium battery production, which includes a winding machine body, on which at least one guiding mechanism is additionally arranged, and the guiding mechanism includes a positioning base, an adjusting arm, a guiding roller, and a positioning roller frame , tension sensor, angle sensor and control circuit, the positioning base is installed on the winding machine body through slide rails, the end and front end of the adjustment arm are respectively hinged with the positioning base and the positioning roller frame through the ratchet mechanism, and the positioning roller frame includes a lifting adjustment mechanism and the carrying frame, wherein there are two carrying frames, and they are symmetrically distributed on the electrode conveying surface of the winding machine body. The carrying frames are connected by a lifting adjustment mechanism, and the guide rollers are embedded in the two carrying frames. On the one hand, the invention can effectively automatically adjust the electrode winding direction and winding tension, and on the other hand, it can clean structures or pollutants such as burrs on the surface and side of the electrode that will affect the performance of the battery.

Description

technical field [0001] The invention relates to an electrode winding device, in particular to a positive and negative electrode 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.

[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
