Abstract
Description
Technical Field
[0001] The utility model relates to the field of winding machines, in particular to a follow-up electric cutter device for a winding machine. Background Art
[0002] With the rapid development of automatic winding machine technology, the application of automatic winding machines in the field of lithium batteries is gradually deepening. In order to improve product quality, reduce production costs and improve production efficiency, battery cell manufacturers are increasingly using automatic winding machines for production and processing.
[0003] The automatic winding machine is a battery cell production equipment that uses multiple winding needles to continuously wind, cut, glue, unload, shape test, and sort the positive and negative electrodes and diaphragm strips. The entire production process only requires manual replacement of materials. The materials are always in rolling friction with the contact parts during the winding process, reducing the risk of scratches and powder loss. As an important winding equipment, the automatic winding machine is widely used in the production of lithium batteries. One person can operate multiple devices, greatly reducing processing time, reducing processing costs, and improving battery cell quality. Compared with traditional winding equipment, the automatic winding machine has the advantages of high winding quality, high winding speed, and multiple functions in one.
[0004] At present, the conventional cutting methods are pneumatic cutting by rapid motor positioning at the detection position or pneumatic cutting by moving the motor after the winding stops at the detection position. Pneumatic cutting by rapid motor positioning will instantly increase the traction of the material, causing the material to jump greatly on the roller, and the material between the winding and the cutter will be arched. The air source and the induction signal delay during the cutting process will result in low cutting accuracy; pneumatic cutting by moving the motor after the winding stops can achieve good cutting accuracy but reduces the production efficiency of the product. At the same time, when finishing the positive electrode material, the two cutting methods will cause the positive electrode material cutting position to be too far away from the winding battery cell position, the correction distance to be too small, and the coverage to be unstable. Utility Model Content
[0005] In view of the above technical problems, the utility model provides an electric cutter device for a winding machine, which can quickly and accurately position the cutter and automatically match the winding speed to improve the cutting accuracy, reduce material bending and cutting The pulling of the material, while increasing the correction distance.
