Abstract

The invention belongs to the technical field of lithium battery winding equipment, and particularly relates to a pole piece deviation rectifying device which comprises a deviation rectifying roller, apressing roller, a pressing driving assembly, a translation driving assembly and a sensor. The deviation rectifying roller and the pressing roller are arranged in parallel and define a pole piece clamping gap; the pressing driving assembly enables the pressing roller to move towards the deviation rectifying roller; the translation driving assembly is connected with the deviation rectifying rollerand is used for driving the deviation rectifying roller to translate so as to clamp a pole piece positioned in the clamping gap to move relative to the sensor; and the translation driving assembly iselectrically connected with the sensor to ensure that the pole piece is at a reference position all the time in the winding process, so that the function of rectifying deviation of the pole piece isrealized, the uniformity of the battery cell is improved, and the quality of the battery cell is improved.

Description

technical field [0001] The invention belongs to the technical field of lithium battery winding equipment, and in particular relates to a pole piece deviation correcting device. Background technique [0002] In recent years, the lithium-ion battery manufacturing industry has developed rapidly, and the process quality requirements for manufacturing battery cells have been continuously improved. In the production process of lithium-ion winding equipment, the pole pieces are formed into cells after the winding process, and the cells are important for ensuring consistent battery performance. , quality stability and other aspects play an important role, but in the prior art, during the winding process of lithium-ion winding equipment, the pole pieces often deviate from the reference position, resulting in low uniformity of the battery cells, which affects the quality of the batteries. quality. Contents of the invention [0003] The object of the present invention is to provide ...
