[0047] The first longitudinal clamping module 4 is slidably connected to a pair of first slide rails 22;

[0048] The second longitudinal clamping module 5 is arranged opposite to the first longitudinal clamping module 4 and is slidably connected to a pair of first slide rails 22.

[0049] Furthermore, such as Figure 1 , 3 As shown in Figure 4, in this embodiment, the lateral clamping module 3 includes:

[0050] A pair of second slide rails 31 are fixedly connected to the positioning plate 2;

Their output ends are connected to the transverse clamping frame 32, which can drive the transverse clamping frame 32 to slide along the second slide rail 31 to achieve the purpose of transversely clamping the square shell battery cell module 6.

[0053] Furthermore, such as Figure 1 , 3 As shown in Figure 4, in this embodiment, the lateral drive mechanism 33 is a manual clamp or a cylinder.

[0069] Second longitudinal clamping frame 51;

[0070] The second longitudinal positioning frame 52 is slidably connected to a pair of second slide rails 31 and fixedly connected to the second longitudinal clamping frame 51, which can drive the second longitudinal clamping frame 51 to move synchronously. The second longitudinal positioning frame 52 is provided with a pair of third positioning holes 521, which can match the first positioning hole 211.

[0071] A pair of second pins 53 are respectively movably disposed in a pair of third positioning holes 521 and can be inserted into the corresponding first positioning hole 211 to fix the second longitudinal positioning frame 52 on the support rail 21.

[0072] The second longitudinal clamping module 5 first determines the positioning reference in the longitudinal direction, and then the square-shell cell module 6 is tightly attached to the second longitudinal clamping frame 51, and the square-shell cell module 6 is clamped by the first longitudinal clamping module; then a pair of transverse clamping modules 3 clamp the square-shell cell module 6 in the transverse direction.

[0073] Furthermore, such as Figure 1 , 4 As shown in Figures 7 and 8, this embodiment further includes: a pair of second copper nozzle clamping mechanisms 54, which are disposed on both sides of the second longitudinal clamping frame 51 and connected to the second longitudinal clamping frame 51, for clamping the copper nozzles used when welding the square-shell battery cell module 6. The second copper nozzle clamping mechanisms 54 and the first copper nozzle clamping mechanism 47 have the same structure.

[0074] Furthermore, such as Figure 4 , 7 As shown, in this embodiment, the second copper nozzle clamping mechanism 54 includes: a third adjusting screw 541 and a second copper nozzle pressing plate 542;

[0075] The third adjusting screw 541 is threadedly connected to the second longitudinal clamping frame 51 and is rotatably connected to the second copper nozzle clamping plate 542.

[0076] The second copper nozzle clamping plate 542 is slidably connected to the second longitudinal clamping frame 51. The copper nozzle is set on the second copper nozzle clamping plate 542. Rotating the third adjusting screw 541 can drive the second copper nozzle clamping plate 542 to clamp the copper nozzle.

[0077] Furthermore, in this embodiment, the third pitch adjusting screw 541 can be replaced with an electric cylinder, a pneumatic cylinder, or a linear motor.

[0079] Working principle: First, slide the second longitudinal positioning frame 52 along the first slide rail 22 to a suitable position, so that the third positioning hole 521 is aligned with the corresponding first positioning hole 211 on the support rail 21. At the same time, the second longitudinal clamping frame 51 moves with the second longitudinal positioning frame 52. Then, insert the second pin 53 into the third positioning hole 521 and the corresponding first positioning hole 211 to fix the position of the second longitudinal positioning frame 52. Place the square shell battery cell module 6 on the support rail 21 and make its left end contact the second longitudinal clamping frame 51. Then, the first longitudinal positioning frame 42 is slid along the first slide rail 22 to a suitable position, so that the first clamping frame is close to the right end of the square-shell battery cell module 6, and the second positioning hole 421 is aligned with the corresponding first positioning hole 211 on the support rail 21. The first pin 43 is inserted into the second positioning hole 421 and the corresponding first positioning hole 211 to fix the position of the second longitudinal positioning frame 52. Then, the first adjusting screw is rotated to move the first longitudinal clamping frame 41 along the first slide rail 22 to clamp the square-shell battery cell module 6. The first adjusting screw is stopped when the pressure sensor 45 reaches the predetermined pressure value. Then, the transverse drive mechanism 33 drives the transverse clamping frame 32 to clamp the square-shell battery cell module 6 from the front and rear directions. Then, the second adjusting screw 471 is rotated to drive the first copper nozzle pressure plate to press the corresponding copper nozzle, and the third adjusting screw 541 is rotated to drive the second copper nozzle pressure plate to press the corresponding copper nozzle. Finally, the robot drives the welding module 1 to weld the side seam.
