For electronic products, such as mobile phones, computers, tablets, digital cameras, smart watches and the like, the use of lithium batteries cannot be avoided, and therefore, a good development platform is created for the development of the lithium battery industry.

At present, a winding machine in the lithium battery industry generally adopts an elliptical winding needle when winding a battery core, and the elliptical winding needle is convenient for prepressing and forming. However, the diameter of the feeding tangent point of the elliptical winding needle is changed continuously during the winding process, so that the winding fluctuation is large, the linear speed of the diaphragm and the pole piece is unstable, and the tension and the alignment degree of the diaphragm and the pole piece during the winding are greatly influenced. Therefore, in order to ensure the product quality, the elliptical winding needle cannot be suitable for high-speed winding occasions, and the linear speed of a winding machine of the elliptical winding needle in the current market can only be below 1m/s, so that the elliptical winding needle is difficult to break through.

The circular winding needle can overcome the problem that the elliptical winding needle generates fluctuation when winding, so that the winding is stable, the winding can be carried out at high speed, the linear speed can reach more than 1m/s when winding, and the production efficiency is improved. However, since the battery cell wound by the circular winding needle is circular, the battery cell is unbalanced in stress after the needle is drawn out or rolls in the moving process, thereby affecting the subsequent processing of the battery cell.
