[0036] See also Figures 1 to 8 The utility model is a welding wire transfer and string welding device, comprising a welding wire transfer and pressing mechanism 4 and a transfer component for driving the welding wire transfer and pressing mechanism 4.

The pressing block 423 is fixed to the clamping jaw seat 422. The plurality of clamping jaws 424 are all arranged on the clamping jaw seat 422. The height of the pressing block 423 protruding from the clamping jaw seat 422 is greater than the height of the clamping jaw 424 protruding from the clamping jaw seat 422.

[0039] The wire pressing assembly 43 includes a plurality of pressing pins 431 , and the pressing pins 431 are used to press the external welding wire clamped by the clamping jaws 424 .

[0040] Specifically, in this embodiment, the welding wire transport and holding mechanism 4 includes a first mounting plate 41, and the first mounting plate 41 includes a bottom plate, a side plate and a reinforcing plate. The output shaft of the longitudinal moving mechanism 3 is connected to the side plate, the side plate is connected to the bottom plate, and the reinforcing plate is connected to the side plate and the bottom plate, so as to enhance the structural stability of the first mounting plate 41 and improve the service life. A plurality of wire clamping assemblies 42 and a plurality of wire pressing assemblies 43 are sequentially arranged along the length direction of the bottom plate, and each wire clamping assembly 42 includes a driving member 421, a clamping claw seat 422, a pressing block 423 and a plurality of clamping claws 424. A plurality of clamping claws 424 are sequentially arranged along the length direction of the clamping claw seat 422, and the length of the clamping claw seat 422 is reversed. It is arranged perpendicular to the length direction of the base plate, and the length direction of the external welding wire is parallel to the length direction of the base plate, that is, each welding wire is clamped by the clamping claws 424 of a plurality of wire clamping assemblies 42, and the working principle is as follows: when the external welding wire is clamped by a plurality of clamping claws 424 from the wire laying table and transported to the external welding table, first the driving member 421 drives the clamping claw seat 422 to descend and approach the welding table, the pressing block 423 first contacts the edge of the battery cell on the welding table, and then the clamping claw 424 releases the welding wire, and the welding wire falls on the surface of the battery cell, the driving member 421 drives the clamping claw seat 422 to move in the opposite direction, and the last welding wire is pressed on the surface of the battery cell by a plurality of pressing pins 431 to enter the welding process.

[0041] By setting up a wire clamping assembly 42 composed of a driving member 421, a clamping jaw seat 422, a pressure block 423 and a plurality of clamping jaws 424, the height of the pressure block 423 protruding from the clamping jaw seat 422 is greater than the height of the clamping jaw 424 protruding from the clamping jaw seat 422, so that the pressure block 423 first contacts the external surface of the battery cell, thereby fixing the battery cell, achieving the purpose of accurately aligning the external welding wire with the surface of the battery cell, and improving the controllability of production quality. Under the action of a plurality of pressing needles 431, the welding wire and the battery cell are in a relatively static state, thereby improving production efficiency and production quality.

[0042] The wire clamping assembly 42 also includes a guide column 425, which is fixed to the first mounting plate 41.

The setting of the guide column 425 ensures the stability of the clamping claw seat 422 in the lifting direction. The setting of the first through hole 411 ensures the stability of the direction of the lifting process of the pressing block 423, that is, ensures the consistency of the position of each battery cell pressed by the pressing block 423. The setting of the second through hole 412 further ensures the stability of the lifting direction of the clamping claw 424, that is, ensures the consistency of the position of each welding wire falling on the surface of different battery cells.

[0043] The wire clamping assembly 42 also includes an opening clamping piece 426, which is arranged above the clamping claw seat 422, and the opening clamping piece 426 is slidably connected to the guide column 425.

Preferably, the middle part of the left claw 4241 and the middle part of the right claw 4242 are connected to the clamping jaw seat 422 through a torsion spring, and the left claw 4241 and the right claw 4242 swing during the lifting and lowering process of the opening clamping piece 426, so as to achieve the purpose of opening and closing of the left claw 4241 and the right claw 4242.

The end of the pressing needle 431 protrudes out of the connecting strip 433 and extends in a direction away from the second mounting plate 432. The setting of the connecting strip 433 prevents the pressing needle 431 from being offset in the vertical direction, further improving the stability of the pressing needle 431 in the vertical direction, thereby improving the stability of the production quality.

[0047] The wire pressing assembly 43 further includes a sleeve 434 , which is disposed between the connecting strip 433 and the second mounting plate 432 .

The transverse moving mechanism 2 is arranged on the bracket 1, and the longitudinal moving mechanism 3 is arranged on the transverse moving mechanism 2. The bracket 1 is used to support the transverse moving mechanism 2, and the transverse moving mechanism 2 is used to carry the longitudinal moving mechanism 3. The longitudinal moving mechanism 3 drives the welding wire transporting and holding mechanism 4, so that the welding wire transporting and holding mechanism 4 can realize spatial movement in the transverse and longitudinal directions to meet the demand for transporting welding wire.

[0049] The wire pressing assembly 43 is located between two adjacent wire clamping assemblies 42, so that the clamping jaws 424 and the pressing needles 431 are evenly distributed along the length direction of the first mounting plate 41, thereby ensuring the uniform distribution of the clamping force along the length direction of the welding wire during the welding wire transfer process and the uniform distribution of the wire pressing force along the length direction of the welding wire during the string welding of the battery cells, thereby further improving the stability of the production quality.
