Abstract

The invention discloses a scoring line crimping sealing device, which comprises a lower frame shaft assembly, a chuck, a pressure head, a scoring wheel, a cam guide rail, a curling wheel and a curling wheel shaft. The collet is supported on the lower frame shaft assembly, the press head is opposite to the collet, the cam guide rail is arranged under the lower frame shaft assembly, and the scoring wheel is arranged on the press the left side of the head. The superior effect of the scoring line crimping sealing device and the crimping sealing method of the present invention is that: the scoring line crimping sealing device can realize one scoring line and two curlings on the battery, and the protrusion of the scoring wheel rushes out on the battery Extended groove. The first crimping enhances the sealing performance of the battery in the radial direction, and the second crimping enhances the sealing performance of the battery in the axial direction. The engraved crimping sealing device changes the sealing method of the battery, increases the crimping pressure, and improves the battery life. safety performance.

Description

technical field [0001] The invention belongs to the technical field of battery sealing, and in particular relates to a line crimping sealing device and a crimping sealing method. Background technique [0002] The battery sealing device plays a decisive role in the leak-proof and explosion-proof safety performance of the battery, so it has high requirements for the sealing structure. The sealing ring in the battery not only affects the battery's leakage resistance and battery explosion-proof safety performance, but also affects the overall performance of the battery discharge capacity. How to increase the effective volume inside the battery to increase the filling amount of active materials in the battery is the key to improving battery performance. The necessary means to reduce the effective volume occupied by the sealing ring in the battery is the key to increasing the filling capacity of the active material in the battery. Therefore, simplifying the structure of the sealin...
