Embodiment Construction

[0024] Embodiments of the present invention will be described in detail below.

[0025] Such as Figure 1 ~ Figure 4 As shown, the present invention discloses an assembly method and assembly device suitable for assembling a square lithium battery pole group, including a cover plate 1 , an insulating stop frame 2 , and a protective film 3 . During the assembly process of the battery cell, firstly, the pole group is welded to the cover plate 3, and the positive and negative tabs of the pole group are welded to the positive and negative connecting pieces of the cover plate 3 to ensure that there is no false welding or over-welding at the welding point.

[0026] The welded electrode group and the electrode group part of the cover plate are placed in the protective film 3 , and the protective film 3 can completely cover the electrode group part after being folded according to the corresponding creases. After wrapping, ensure that the first hole 31 and the second hole 32 on the pro...

Abstract

The invention discloses an assembling apparatus and an assembling method suitable for assembling a square lithium battery pole group. The assembling apparatus comprises a cover plate, an insulating locking frame and a protection film; the electric core is fixed through a reasonable assembly of integrating the three parts of the cover plate, the insulating locking frame and the protection film into one body, and the phenomena of short circuit between the positive electrode and the negative electrode, short circuit between the positive electrode and the shell, and short circuit between the negative electrode and the shell in the internal can be prevented; the protection film body is made from a PE material used for protecting the surface of the pole group on one hand, and for isolating the pole group from the shell on the other hand so as to prevent the shell from being electrified to realize the insulating effect; small holes are formed in the two sides of the upper part of the protection film; the insulating locking frame penetrates from the holes to connect the insulating locking frame and the protection film into one body; the insulating locking frame comprises a left part and a right part, and insulating locking frame is connected with the protection film in one body; the left part and the right part are connected by adopting a clamping groove extruding and inserting mode, so that the assembling process is simplified; a fixed slot is formed in the lower part of the cover plate; and the insulating locking frame penetrates through the slot, so that the assembly of integrating the three parts of the cover plate, the insulating locking frame and the protection film into one body is realized.

Description

technical field [0001] The invention relates to the field of lithium ion batteries, in particular to an assembly device and an assembly method suitable for assembling square lithium battery pole groups. Background technique [0002] At present, new energy vehicles are developing at full speed. For the main components of new energy vehicles, lithium batteries, all automobile manufacturers have put forward strict requirements, both in terms of quality and quantity. The manufacturing process of lithium batteries is also becoming more and more simplified and automated, and the assembly in the manufacturing process has always been less automated due to its many operating steps, many and small internal structural parts, and high requirements. More human resources are required. Therefore, improving the efficiency of the assembly process has become an important means to increase the production capacity of the lithium battery industry. [0003] Square lithium batteries have the cha...
