Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: Please refer to Figures 1-10 A busbar welding nozzle structure includes: a nozzle assembly and a nozzle holder 1 mounted on a drive module; an insertion assembly mounted on the nozzle holder 1 for detachably mounting the nozzle assembly on the nozzle holder 1; the insertion assembly includes an insertion base 2 mounted on the lower end of the nozzle holder 1, and an insertion top seat 21 mounted on the upper half of the nozzle holder 1. Both the insertion base 2 and the insertion top seat 21 have a snap-fit ​​edge extending from their front sides. The nozzle assembly is inserted between the insertion base 2 and the insertion top seat 21. The insertion top seat 21 is also provided with an insertion pin 22, the end of which is inserted into an insertion hole opened at the upper end of the insertion plate 13 of the nozzle assembly. In this embodiment, the insertion pin 22 is a spring pin. The drive module can specifically be a servo electric cylinder. By driving the nozzle holders 1 on both sides to move closer together through the servo electric cylinders on both sides, the nozzle assemblies on both sides can press the busbar onto the battery module, facilitating welding.

[0017] The working principle of this utility model is as follows: During installation, pull the insert pin 22 upward, and then insert the insert plate 13 of the nozzle assembly between the insert base 2 and the insert top seat 21. The snapping edge on the front side of the insert base 2 and the insert top seat 21 can press the insert plate 13 in place. Then, insert the end of the insert pin 22 into the insertion hole at the upper end of the insert plate 13 to complete the installation. During disassembly, simply pull the insert pin 22 upward and then pull out the insert plate 13 to complete the disassembly. The operation is simple and convenient for replacement, which can better meet the welding work of different busbars.

[0018] As a further embodiment, the nozzle assembly includes an insert plate 13 and a nozzle body 11. A through hole is provided in the middle of the nozzle body 11, and a connecting sleeve 111 extends from the rear side of the nozzle body 11. The connecting sleeve 111 is inserted into a welding port 15 on the insert plate 13. The welding port 15, in conjunction with the through hole, facilitates welding operations.

[0019] As a further embodiment, a buffer assembly is provided between the nozzle body 11 and the insert plate 13. The insert plate 13 has a plurality of buffer holes 16 distributed on it. The buffer assembly includes a buffer spring 4 installed on the rear side of the nozzle body 11. A buffer sleeve 41 is also installed at the end of the buffer spring 4. The buffer sleeve 41 is inserted into the front half of the buffer hole 16. A buffer rod 42 is also inserted into the rear half of the buffer hole 16. A buffer threaded section 43 is provided at the end of the buffer rod 42. The buffer threaded section 43 is threadedly connected to the nozzle body 11. In this embodiment, the buffer spring 4 is fitted on the outside of the buffer rod 42.

[0020] By setting up a buffer component, when the battery module is pressed and fixed, the buffer spring 4 can buffer the instantaneous impact force generated when the drive module drives the pressure nozzle body 11 to press, thereby reducing damage to the battery module and better meeting the usage requirements.

[0021] As a further embodiment, the insertion plate 13 is also provided with a connecting hole 17, in which a connecting rod 3 is slidably inserted. A connecting rod 32 is installed at a corresponding position on the rear side of the nozzle body 11. The connecting rod 3 and the connecting rod 32 are fixedly connected by a connecting screw 33. By setting the connecting rod 3 in conjunction with the connecting rod 32, the stability of the movement of the nozzle body 11 can be improved.

[0022] As a further embodiment, a smoke exhaust pipe 12 is also installed on the upper end of the nozzle body 11. The smoke inlet of the smoke exhaust pipe 12 is connected to a through hole on the nozzle body 11, and the other end of the smoke exhaust pipe 12 is inserted into a smoke exhaust port 14 opened on the insertion plate 13. A smoke exhaust seat 10 is installed at a corresponding position on the rear side of the nozzle holder 1. The smoke inlet of the smoke exhaust seat 10 extends into the smoke exhaust port 14, and a smoke exhaust hood is also installed on the smoke exhaust seat 10. In this embodiment, a vent pipe is provided on the smoke exhaust hood, and an exhaust pump is also provided on the vent pipe to facilitate the discharge of welding exhaust gas.

[0023] By setting up the exhaust pipe 12, the waste gas generated during welding can be easily discharged into the exhaust port 14. Then, the waste gas is guided into the exhaust hood through the inlet pipe and finally discharged, which can effectively prevent the waste gas from polluting the processing workshop.
