Description

A multi-pole sheet group linkage pressing and cutting device with width adjustment function technical field The present invention relates to the field of lithium ion batteries, especially a kind of lithium ion power battery with width adjustment in the field of lithium ion power batteries. A functional multi-pole sheet group linkage pressing and cutting device. Background technique As the country vigorously promotes the development of new energy, the demand for lithium-ion power batteries in all walks of life is increasing day by day. In the composition of the ion power battery, the battery cell is its core component, and the battery cell is generally formed by overlapping positive and negative electrode sheets. The composition structure of the battery cell includes a plurality of positive and negative electrode sheets that are staggered and stacked up and down, and the positive and negative electrode sheets are isolated and insulated by a diaphragm.

However, in the unit body manufacturing process of this manufacturing process, the unit body is made using a blind stacking method, that is, the positive and negative electrodes are synchronously transported in a straight line and laminated, and the positive and negative electrodes arranged up and down lack alignment, which cannot To ensure the accuracy of the positive and negative electrodes in the unit, at the same time, the current situation is that if the alignment process is added to the positive and negative electrodes arranged above and below each piece, it will take the same time as the existing single-chip stacking process, and it will also consume a lot of time. Lamination efficiency cannot be guaranteed
