Abstract

The invention discloses a battery lamination device which comprises a lamination device, positive and negative pole boxes, positive and negative pole taking units, positive and negative pole feeding units and positive and negative pole positioning tables. The lamination device is set to move longitudinally along a straight line; the part formed by the positive positioning table, the positive polefeeding unit and the positive pole taking unit and the part formed by the negative pole positioning table, the negative pole feeding unit and the negative pole taking unit are arranged in parallel onthe same side of the moving direction of the lamination device; the positive pole taking unit and the positive pole feeding unit are linked horizontally, and the positive pole feeding unit is closer to the lamination device; the negative pole taking unit and the negative pole feeding unit are linked horizontally, and the negative pole unit is closer to the lamination device; and the taking units and the feeding units take pole pieces out of the pole piece boxes and the positioning tables respectively and simultaneously approach to the lamination device. After the lamination device moves to the same straight line with the taking units and the feeding units, the taking units and the feeding units put the pole pieces on the positioning tables and the lamination device respectively and simultaneously.

Description

technical field [0001] The invention relates to power battery production equipment, in particular to battery lamination equipment. Background technique [0002] Energy storage lithium batteries are developing towards high power. At present, high-power lithium batteries are often made by separating the positive and negative electrodes with a diaphragm, and the diaphragm and the electrode are overlapped repeatedly. Each battery requires dozens or even hundreds of pairs of electrodes. The pieces are stacked, and the workload is very large. [0003] The battery stacking equipment makes batteries by taking out the positive and negative electrode sheets cut and formed by the forming equipment from the magazine and stacking them up. Patent No. 200820093966.4 is an automatic lamination machine, its structure includes: frame, set on the frame, for transporting the sheet feeding mechanism of positive and negative electrode sheets to be laminated, it is characterized in that, further ...
