Description

technical field [0001] The invention relates to the field of energy storage devices, in particular to a device for preparing laminated electric cores. Background technique [0002] The production process of lithium-ion battery cells generally includes a winding process and a stacking process. The cells produced by the stacking process have the advantages of high capacity and low internal resistance, and the cells produced by the stacking process have various shapes. Designed for needs. [0003] According to the difference of the separator used, the lamination process can be divided into: 1) the ordinary lamination process, that is, the strip-shaped anode pole piece, the separator film and the cathode pole piece are cut into the required sheet shape at the sheet machine (i.e. sheet), and then stacked in order on the stacking platform (that is, stacking) to obtain stacked cells; cut into the required sheet (ie, sheet), and then press-fit the sheet-shaped anode and cathode sh...

AI Technical Summary

Problems solved by technology

[0005] Therefore, in the traditional lamination process, since the lamination process and the lamination process are completed by two independent devices, which are not related to each other, it is necessary to perform at least two positioning of the materials to be stacked, that is, the Positioning and positioning during lamination, and the auxiliary time between the sheet-making process and the lamination process is long (that is, the time for putting the cut material into the material box and transporting the material box to the designated material box of the stacker The time at the position), the production efficiency is low, and the materials to be stacked (such as the anode electrode and the cathode electrode) are transferred many times, and the powder of the electrode sheet and the corner of the electrode sheet are easy to occur during the transfer process.
