Embodiment

[0053] see figure 1 , figure 1 Shown is a flow chart of the battery packaging method provided in this embodiment. The battery packaging method provided in this embodiment is applied to such as figure 2 The battery casing 10 with the cover plate 11 and the box body 12 as shown has the characteristics of convenient and quick operation and better sealing, and specifically includes the following steps:

[0054] Step S101 , applying glue to one side of the cover plate 11 to form the glue layer 13 .

[0055] The structure of the cover plate 11 coated with glue to form the glue layer 13 is as follows: image 3 As shown, in this embodiment, the colloidal layer 13 is annular, and its shape and structure correspond to the opening of the box body 12 , so as to ensure that when the cover plate 11 is closed on the box body 12 , the colloidal layer 13 can interact with the box body 12 . The opening peripheral edge of the case 12 is in contact.

[0056] In the actual gluing process, glu...

Abstract

The invention discloses a battery packaging method and system and a battery, and relates to the technical field of batteries. The battery packaging method is applied to a battery shell, the battery shell comprises a cover plate and a box body, and the battery packaging method comprises the following steps: gluing one side of the cover plate to form a gelatinous layer; the side, where the gelatinous layer is located, of the cover plate covers the box body so that the gelatinous layer can make contact with the box body; and interval laser welding is carried out on the contact track of the cover plate and the box body, so that a gap between the cover plate and the box body is filled with the gelatinous layer after the gelatinous layer is heated and melted. The battery packaging method provided by the invention is convenient and rapid to operate, time-saving and labor-saving, and better in sealing effect.

Description

technical field [0001] The present invention relates to the field of battery technology, and in particular, to a battery packaging method, system and battery. Background technique [0002] At present, when the battery is packaged through the casing on the market, the cover plate is generally welded directly on the box body. There are mainly two welding methods, one is full-scale welding along the contact track, which is cumbersome, time-consuming and labor-intensive; the other is spot welding at intervals along the contact track, which has poor sealing performance of the shell. problem, there is a risk of fluid leakage. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a battery packaging method, which has the characteristics of convenient and quick operation and better sealing performance. [0004] Another object of the present invention is to provide a battery packaging system, which has the characteristics of convenient and quick ope...
