[0028] The technical solutions of the present application will be further described below in combination with the drawings and through specific embodiments.

[0029] As shown in Figures 1 to 6 , a welding strip pressing device comprises a pressing device body 1 and a plurality of jaw sets 2 arranged side by side and spaced apart on the pressing device body 1; one side of the pressing device body 1 is provided with a supporting portion 3 for supporting the end of a welding strip, and the supporting portion 3 is located below each jaw set 2; wherein the jaw set 2 can clamp the welding strip supported by the supporting portion 3.

[0030] Specifically, in the present embodiment, the pressing device body 1 preferably has a U-shaped structure, and a plurality of mounting grooves are spaced apart on the side of the pressing device body 1 away from the opening thereof, and one mounting groove is provided with one jaw set 2.

[0031] As shown in Figure 2 , the jaw set 2 comprises two oppositely arranged jaws 21 and at least one elastic member. Wherein the jaws 21 are rotationally connected with the pressing device body 1, and the two jaws 21 are in a closed state under the elastic force of the elastic member; the side of the two jaws 21 away from the clamping end is provided with a trigger rod 22, and a trigger gap is arranged between the two trigger rods 22.

[0032] In the present embodiment, the elastic member can be connected between the two jaws 21, or a plurality of elastic members can be distributed on the opposite sides of the two jaws 21. Wherein the elastic member is preferably a spring.

[0033] Preferably, the clamping end of the two jaws 21 is located on the side of the supporting portion 3 away from the pressing device body 1, so as to clamp the overhanging part of the welding strip; wherein the overhanging part of the welding strip refers to the part of the welding strip suspended above the battery piece due to the support of the end of the welding strip by the supporting portion 3. By adopting the structure, the clamping end of the two jaws 21 can be prevented from contacting the battery piece and the supporting portion 3, which facilitates the clamping of the two jaws 21 on the welding strip and can also prevent the clamping end of the two jaws 21 from damaging the battery piece.

[0036] Further, the supporting part 3 is one or a plurality of supporting parts arranged at intervals, and one supporting part 3 supports at least one solder strip. When all the solder strips are supported by one supporting part 3, it is convenient for processing and forming; when a plurality of supporting parts arranged at intervals are used (for example, one supporting part supports one solder strip), it is beneficial to reduce the weight of the solder strip press.

[0037] In the embodiment, the upper extension part 41 is provided with the avoiding groove 411 for avoiding the solder strip, as shown in Figure 3 and 4 .

[0038] In the embodiment, a group of abutting grooves 13 are arranged on one side of the press body 1, so that the solder strip press is pushed by the taut push hand to move along the direction of the battery piece conveying. In order to facilitate the movement of the solder strip press, a group of rollers 5 can be arranged on the press body 1. Preferably, the rollers 5 are arranged on the two opposite sides of the press body 1.

[0039] The solder strip press is used, two trigger rods 22 are pushed outward by external force to drive the two clamping jaws 21 to open; the solder strip is placed, the end of the solder strip passes between the two clamping jaws 21 and falls on the supporting part 3; the external force is removed, and the elastic force of the elastic member is used to close the two clamping jaws 21, so as to realize the clamping and fixing of the solder strip. The solder strip press uses the supporting part 3 to support the end of the solder strip, which can facilitate the firm clamping of the clamping end of the two clamping jaws 21 on the solder strip, and the clamping jaw 21 will not contact the surface of the battery, that is, the clamping effect of the solder strip is ensured, and the surface of the battery piece is not scratched.
