Multi-pole piece group linkage pressing piece cutting device with width adjusting function

Abstract

The invention discloses a multi-pole piece group linkage pressing piece cutting device with a width adjusting function. The device comprises a supporting and adjusting assembly, cutting assemblies and a piece cutting assembly; the supporting and adjusting assembly comprises a supporting part, a driving part and adjusting parts; the supporting part is horizontally arranged, and the two sets of driving parts are arranged on the two sides of the supporting part correspondingly; at least two groups of adjusting parts are provided, the adjusting parts are movably arranged on the supporting part, and the two groups of adjusting parts are connected with the output ends of the two groups of driving parts; the cutting assemblies are horizontally arranged below the supporting and adjusting assembly and connected with the adjusting component; and at least two groups of piece cutting assemblies are provided, are horizontally arranged under the supporting and adjusting assembly, and are respectively connected with the adjusting part. The multi-pole piece group linkage pressing piece cutting device is suitable for a multi-pole piece laminating process, has a piece pressing and cutting-off linkage function, guarantees the cutting precision, improves the cutting-off efficiency and has a width linkage adjusting function.

Description

technical field [0001] The invention relates to the field of lithium-ion batteries, in particular to a multi-pole sheet group linkage tablet pressing and cutting device with a width adjustment function in the field of lithium-ion power batteries. Background technique [0002] 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 structure of lithium-ion power batteries, the battery core is its core component. become. The structure of the battery cell includes multiple positive and negative plates stacked up and down staggered, and the positive and negative plates are isolated and insulated by a diaphragm. [0003] At present, the manufacturing process of the battery cell includes two methods of strip lamination and single-piece lamination according to the different diaphragm insertion process, that is, continuous diaphragm and single-piece diaphragm lamin...

AI Technical Summary

Problems solved by technology

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
