Embodiment 1

[0035] Figure 1 to Figure 5 A preferred embodiment of a cylindrical battery welding jig according to the present invention is shown. As shown in the figure, the cylindrical battery welding jig includes a frame body 1 for placing the battery module 10. The bus plate on the top is fixed and pressed on the battery module, wherein the bus plate includes a board body and a plurality of bus bars located on the board body, and the plurality of bus bars correspond to the positions of the battery electrodes of the battery module 10 one by one. . The pressing plate 2 is provided with a welding operation window 23 for one-to-one welding of a plurality of bus bars and a plurality of cell electrodes. When in use, the pressure plate 2 is opened, the battery module 10 is placed in the frame body 1, and the bus plate is covered on the battery module 10, and the multiple bus pieces on the bus plate are connected with the multiple batteries of the battery module 10. The positions of the cor...

Abstract

The invention relates to the technical field of battery assembling, and particularly relates to a welding clamp for cylindrical battery. The welding clamp for the cylindrical battery comprises a framebody in which a battery mould can be placed, wherein pressing plates are correspondingly mounted at a front frame opening and a rear frame opening of the frame body, and a collecting plate positionedon the battery mould is pressed on the battery mould through the pressing plates; a plurality of collecting sheets on the collecting plate are corresponding to a plurality of cell electrodes of the battery mould; and welding operating ports through which the collecting sheets are welded with the cell electrodes in a one-to-one correspondence manner are formed in the pressing plates. With the adoption of the welding clamp for the cylindrical battery, the battery mould can be reliably fixed, and the collecting plate is compressed on the battery mould; the welding can be performed through the welding operating ports; and in addition, the welding clamp is high in welding quality, stable in structure, and convenient and simple to operate.

Description

technical field [0001] The invention relates to the technical field of battery assembly, in particular to a cylindrical battery welding jig. Background technique [0002] At present, in the group assembly process of cylindrical lithium-ion batteries, double-needle spot welding is a relatively common welding method. The nickel sheet and the battery electrode are pressed tightly by the welding needle, and the solder is melted by the current of several thousand amperes. In order to connect the nickel sheet and the electrode of the battery cell together, it has the advantages of low cost, simple operation, energy saving and the like. [0003] In the spot welding process, in order to improve efficiency, the positive and negative electrodes are generally spot welded at the same time, so that the battery will be impacted from two directions. If it is not fastened, the position will change greatly. The welded nickel sheet is generally relatively small in terms of cost and flow dive...
