Abstract

The invention discloses a spot welding jig for a lithium battery pack. The spot welding jig comprises a cuboid-shaped jig shell, wherein the lithium battery pack to be subjected to spot welding is placed in the cavity of the jig shell; two ventilation holes used for dissipating heat are formed in each of the two sides of the jig shell up and down; a spot welding cover plate is hinged to one side of the upper surface of the jig shell; a rectangular through hole is formed in the upper surface of the spot welding cover plate; the rectangular through hole is connected with a locating plate in a clamping manner; locating slots used for locating the anodes of lithium battery single bodies in the lithium battery pack are formed in the locating plate at equal intervals; a fixed clamping plate is arranged between the front end of the spot welding cover plate and the jig shell. According to the spot welding jig for the lithium battery pack provided by the invention, lithium battery packs composed of lithium battery single bodies with different numbers can be located and fixed, spot welding for a conductive copper sheet is facilitated, and the spot welding jig is simple in structure, easy to achieve and good in application prospect.

Description

technical field [0001] The invention belongs to the technical field of lithium battery pack welding, and in particular relates to a spot welding jig for lithium battery packs. Background technique [0002] Lithium battery packs have strong power storage capacity, light weight, energy saving and environmental protection, so they have been widely used. At present, the common lithium battery packs on the market are composed of multiple cylindrical lithium battery cells connected in series and parallel. When using conductive copper sheets to connect multiple lithium battery cells in series and parallel, it is necessary to connect the conductive copper sheets spot welding of the positive electrode, in order to improve the efficiency of spot welding, spot welding machines are often used for spot welding, however, when multiple lithium battery cells are spot welded, the fixing effect is not good, which may easily lead to deviation of the spot welding position or false welding , af...
