A battery composite pole piece coating and lamination machine

Abstract

The invention discloses an electric core compound pole piece coating and lamination integrated machine, which includes a machine platform, which is equipped with a lamination mechanism, a pole piece storage and feeding mechanism, a composite pole piece coating mechanism, and a composite pole piece handling mechanism. Mechanism and cell unloading mechanism, the compound pole piece coating mechanism includes a four-station turntable and a coating mechanism. After the coating mechanism coats multiple pole pieces, the four-station turntable will It is transported to the handling station of the composite pole piece handling mechanism, and the composite pole piece handling mechanism transports the composite pole piece to the pole piece storage and feeding mechanism for storage. The present invention adopts the method of covering multiple pole pieces at the same time in the previous process, and then laminates the pole pieces first, which saves the cumbersome steps of padding the diaphragm when the pole pieces are laminated, and does not need to install the diaphragm. For tension adjustment, etc., the method of coating multiple pole pieces in the previous process can speed up the efficiency of pole piece coating, simplify the complexity of the lamination mechanism in the latter stage, and improve the stacking efficiency.

Description

technical field [0001] The invention relates to the field of electric core production, in particular to an integrated machine for coating and laminating electric core composite pole pieces. Background technique [0002] With the rapid development of electronic products, the demand for lithium batteries is getting higher and higher, and the requirements for the production process and production efficiency of lithium batteries are also getting higher and higher. In the existing technology, the cells of lithium batteries are composed of The positive electrode sheet and the negative electrode sheet are stacked, so the stacking process is one of the most important processes in the battery manufacturing process. Because the separator needs to be separated from the polar sheet during the stacking process, the wrapping of the separator The effect requirements are high, and the adjustment of the diaphragm is cumbersome, resulting in generally low lamination efficiency, which needs to...

At the same time, the requirements for the production process and production efficiency of lithium batteries are also getting higher and higher. In the existing technology, the cells of lithium batteries are made of The positive electrode and the negative electrode are stacked, so the lamination process is one of the most important processes in the battery manufacturing process. Since the electrode sheet and the electrode sheet need to be separated by a diaphragm during the lamination process, the packaging of the diaphragm The effect requirements are high, and the adjustment of the diaphragm is cumbersome, resulting in generally low lamination efficiency, which needs to be improved
