Integrated equipment for manufacturing battery pole piece and winding battery cell

Abstract

The invention discloses integrated equipment for manufacturing battery pole pieces and winding a battery cell. The equipment comprises a winding part deviation correcting mechanism used for correcting the deviation of at least one of the positive pole piece and the negative pole piece after the pole pieces are manufactured, and the winding part deviation correcting mechanism comprises a motor, a cam, a transition wheel bracket, a transition wheel shaft, a transition wheel, a rotating shaft and a deviation correcting detection mechanism, wherein an output shaft of an electrode is coupled to the cam; the transition wheel bracket is elastically connected with a stand through an elastic component; the output end of the cam acts on one end of the transition wheel bracket, while the other end of the transition wheel bracket is pivotably fixed on the rotating shaft; the rotating shaft is fixed on the stand, and the transition wheel shaft is fixed on the transition wheel bracket; the transition wheel is arranged on the transition wheel shaft; and the pole pieces pass through on the transition wheel.

Description

technical field [0001] The invention relates to battery production equipment, in particular to an integrated equipment for battery pole sheet production and battery core winding. Background technique [0002] At present, the sheet production and the winding of the battery core are completed separately by separate equipment. After the positive and negative electrode sheet materials are welded on the tab welding machine and pasted with protective tape, according to the requirements of different winding equipment, the positive 1. The negative electrode sheet is cut to a fixed length or collected into a roll; then the prepared positive and negative electrode sheets are placed on a semi-automatic or fully automatic winding device, and the sheet is manually or automatically loaded for winding and forming to complete the cell. winding action. If it is fixed-length cutting, the winding is completed by semi-automatic winding equipment. The semi-automatic equipment is manually fed in...

AI Technical Summary

Problems solved by technology

If it is fixed-length cutting, the winding is completed by semi-automatic winding equipment. The semi-automatic equipment is manually fed into the film. Due to manual direct contact during winding, it is easy to cause cross-contamination of positive and negative electrodes, which directly affects the final battery capacity; If the material is collected into rolls, automatic winding equipment is used for winding, but the requirements for material rolls are relatively high during film production. It is difficult to achieve consistent alignment of rolls and materials in the current technology. In the subsequent winding process, the difficulty of rectifying the deflection will be increased. If the pole piece is deflected, the alignment of the end face of the cell will be inconsistent, which will greatly affect the quality of the cell.
