Lithium battery with protection apparatus and assembling machine of lithium battery

Abstract

The invention relates to a lithium battery with a protection apparatus. The lithium battery comprises a battery main body, copper sheets and a cover plate; the upper and lower surfaces of each coppersheet are pasted with a nickel strap and an adhesive tape in sequence; positioning holes are formed in the upper and lower parts of the two ends on the inner side of the cover plate respectively, andan upper protection inserting block and a lower protection inserting block are mounted in the positioning holes in the upper and lower parts by matching with positioning columns respectively; the upper protection inserting block comprises an upper protection block main body matched with one side, close to the cover plate, of the upper part copper sheet; a protection positioning block inserted to the space between the two groups of copper sheets is arranged in the middle position of the upper protection block main body; a protection positioning inserting groove is formed in the lower part of the protection positioning block; the lower protection inserting block comprises a lower protection block main body matched with one side, close to the cover plate, of the lower part copper sheet; and aprotection positioning inserting block is arranged on the lower protection block main body. The protection apparatus, which is mounted on the cover plate and formed by upper protection inserting block and the lower protection inserting block in a buckling manner, is arranged between the battery main body and the cover plate of the lithium battery, so that it is ensured that the copper sheets do not suffer from displacement, thereby prolonging the service life of the lithium battery.

Description

technical field [0001] The invention relates to the field of application and processing of lithium batteries for vehicles, in particular to a lithium battery with a protection device and an assembly machine thereof. Background technique [0002] Lithium battery for vehicles is a commonly used product with a wide range of applications, such as Figure 10 As shown, most of them include a battery body 55 and a cover plate 56. There are two sets of copper sheets connected to the battery body between the cover plate and the battery body. The upper and lower surfaces of the copper sheets are sequentially pasted with nickel tape and high-temperature tape. [0003] Existing lithium batteries for vehicles have certain defects. In the process of processing and subsequent use, copper sheets are prone to dislocation, which will lead to damage and scrap of lithium batteries, and reduce the normal service life of lithium batteries.
