Abstract
The utility model discloses a battery needle-winding component. The battery needle-winding component is mounted on a battery winding machine; the battery winding machine comprises a base as well as a motor mounted on the base; the battery needle-winding component includes a fixed needle body and a movable needle body; the fixed needle body is connected with the drive shaft of the motor; the fixed needle body is driven by the motor to rotate; at least one of the fixed needle body and the movable needle body is provided with a cambered surface. Owing to the fact that at least one of the fixed needle body and the movable needle body of the battery needle-winding component is provided with one cambered surface, positive pole plates, negative pole plates and thin films can be wound to form semi-finished products of arc-shaped winding cores with each winding core provided with a cambered surface on one side through the battery needle-winding component, or can be directly wound to form arc-shaped winding cores; during the process of pressing the semi-finished products of the arc-shaped winding cores to obtain the arc-shaped winding cores, relative movement of the positive pole plates and the negative pole plates is avoided, and the thin films cannot be damaged. The harm to the winding cores caused by bending the winding cores to obtain the arc-shaped winding cores can be effectively reduced in virtue of the directly formed arc-shaped winding cores. Compared with the conventional arc-shaped winding cores, the directly formed arc-shaped winding cores are higher in safety performance.
