[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0032] The following is a reference appendix. Figure 1-4 Description of a busbar welding assembly 100 according to an embodiment of the present utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 4 The busbar welding assembly 100 according to an embodiment of the present utility model includes: a base plate 10, a mounting plate 20 and a drive component 40.

[0034] Specifically, the mounting plate 20 is connected to the base plate 10, and the mounting plate 20 is provided with a nozzle 30. The nozzle 30 is used for welding the busbars of the battery pack. The nozzle 30 includes a first nozzle 31 and a second nozzle 32, which are aligned along a first direction (e.g., ...). Figure 4 The nozzles are arranged at intervals in the front-to-back direction (as shown); the drive unit 40 is connected to the base plate 10, and the drive unit 40 drives the first nozzle 31 or the second nozzle 32 to move in the first direction to adjust the distance between the first nozzle 31 and the second nozzle 32.

[0035] For example, such as Figure 1 , Figure 2 and Figure 4 As shown, the first nozzle 31 and the second nozzle 32 are arranged at intervals along the front-back direction on the mounting plate 20. The first nozzle 31 is located on the front side of the second spray group, and the driving member 40 drives the first nozzle 31 to move in the front-back direction.

[0036] When welding busbars using busbar welding assembly 100, if two types of battery packs are produced on the same production line, such as lithium iron phosphate battery packs and ternary lithium battery packs, and the spacing of the busbar plates of the two different battery packs is different, the drive unit 40 drives the first nozzle 31 to move until the spacing between the first nozzle 31 and the second nozzle 32 matches the distance between adjacent plates, thereby ensuring that busbar welding assembly 100 can adapt to the production of multiple battery packs.

[0037] The busbar welding assembly 100 of this utility model is provided with relatively movable nozzles 30. By adjusting the distance between the first nozzle 31 and the second nozzle 32, it can adapt to the spacing of busbar plates of various battery packs. Compared with the prior art, which requires disassembling the nozzles 30 and then moving them to a suitable position for repositioning, the busbar welding assembly 100 of this application can save the time of disassembling tooling, improve welding efficiency, and thus ensure production efficiency. At the same time, it can improve the versatility of the busbar welding assembly 100, eliminating the need for mold design for a single battery pack, thereby reducing the cost of use.

[0038] Furthermore, by adjusting the distance between the first nozzle 31 and the second nozzle 32 through the drive component 40, rework caused by errors in manually replacing the nozzle 30 in the prior art can be effectively avoided, thereby further improving production efficiency.

[0039] According to an embodiment of the present invention, the busbar welding assembly 100 is provided with a relatively movable nozzle 30, which can save the time of disassembling tooling and improve welding efficiency, thereby ensuring production efficiency. At the same time, it can improve the versatility of the busbar welding assembly 100 and reduce the cost of use.

[0040] According to some embodiments of this utility model, refer to Figure 2 and Figure 3 There are two mounting plates 20, namely a first mounting plate 21 and a second mounting plate 22. The first nozzle 31 is fixed to the first mounting plate 21, and the second nozzle 32 is fixed to the second mounting plate 22. The first mounting plate 21 can move relative to the second mounting plate 22. Thus, the first mounting plate 21 can drive the first nozzle 31 to move relative to the second nozzle 32, thereby avoiding the drive component 40 from directly driving the first nozzle 31 and damaging it, thus protecting the first nozzle 31.

[0041] For example, such as Figure 2 and Figure 3As shown, the first nozzle 31 is fixed to the first mounting plate 21, and the second nozzle 32 is fixed to the second mounting plate 22. The first mounting plate 21 can move relative to the second mounting plate 22 in the front-back direction. Preferably, the first nozzle 31 is screwed to the first mounting plate 21, which facilitates the installation and removal of the first nozzle 31. The second nozzle 32 is screwed to the second mounting plate 22, which facilitates the installation and removal of the second nozzle 32. Furthermore, bolts with a diameter of 6mm can be used for fixing, thereby ensuring the strength of the bolts.

[0042] According to some optional embodiments of the present invention, refer to Figure 4 The busbar welding assembly 100 includes: a fixing plate 50, which is fixed to the base plate 10; a drive member 40, which is fixed to the base plate 10 via the fixing plate 50; and a drive rod of the drive member 40, which is connected to a first mounting plate 21. Thus, the fixing plate 50 provides a fixed position for the drive member 40, facilitating its arrangement. Simultaneously, the fixing plate 50 ensures stability between the drive member 40 and the fixing plate 50, effectively preventing separation of the drive member 40 from the base plate 10.

[0043] For example, such as Figure 4 As shown, the fixing plate 50 is disposed between the driving member 40 and the base plate 10. The driving member 40 is fixed on the fixing plate 50, and the front end of the driving rod of the driving member 40 is connected to the first mounting plate 21. Preferably, the fixing plate 50 is screwed to the base plate 10, which facilitates the installation and removal of the fixing plate 50. Furthermore, bolts with a diameter of 8mm can be used for fixing, thereby ensuring the strength of the bolts.

[0044] According to some embodiments of this utility model, refer to Figure 4 One of the first mounting plate 21 and the base plate 10 is provided with a slide rail 11, and the other is provided with a sliding groove. That is, the first mounting plate 21 can be provided with the slide rail 11 and the base plate 10 can be provided with the sliding groove, or the base plate 10 can be provided with the slide rail 11 and the first mounting plate 21 can be provided with the sliding groove. The slide rail 11 moves within the sliding groove. This ensures the smooth movement of the first mounting plate 21 relative to the base plate 10, thereby preventing the first mounting plate 21 from shaking during movement. At the same time, the part where the sliding groove connects to the slide rail 11 can provide a support point for the first mounting plate 21, thereby further reducing the shaking of the first mounting plate 21.

[0045] For example, such as Figure 4 As shown, a groove is formed on the first mounting plate 21, which extends in the front-to-back direction, and a slide rail 11 is formed on the base plate 10, which slides in the groove in the first direction.

[0046] According to some optional embodiments of the present invention, refer to Figure 2 and Figure 3Two slide rails 11 are mounted on the base plate 10, spaced apart. These two slide rails 11 provide two support points for the first mounting plate 21, ensuring the smooth movement of the first mounting plate 21 relative to the base plate 10. For example, as... Figure 2 and Figure 3 As shown, the slide rail 11 is mounted on the base plate 10, and the two slide rails 11 are arranged at intervals along the left and right directions on the base plate 10.

[0047] According to some embodiments of this utility model, refer to Figure 2 and Figure 3 The busbar welding assembly 100 includes an elastic element 71 and a sensor 72. The elastic element 71 is disposed between the nozzle 30 and the mounting plate 20, and the sensor 72 is used to detect the elastic deformation of the elastic element 71. Thus, the pressure spring bears the pressure between the nozzle 30 and the mounting plate 20, thereby preventing the nozzle 30 from directly contacting the mounting plate 20 and causing damage. Simultaneously, the sensor 72 can detect whether the nozzle 30 has moved to a suitable position, thereby ensuring appropriate contact pressure between the nozzle 30 and the mounting plate. Furthermore, the detection by the sensor 72 can keep multiple nozzles 30 on the same horizontal plane, thereby ensuring the levelness of the multiple nozzles 30.

[0048] For example, such as Figure 2 and Figure 3 As shown, the elastic element 71 extends in the vertical direction. The upper end of the elastic element 71 is connected to the base plate 10, and the lower end of the elastic element 71 is connected to the mounting plate 20. The sensor 72 is a vertical sensor 72, which is connected to the upper end of the elastic element 71.

[0049] According to some optional embodiments of the present invention, refer to Figure 1 and Figure 2 The number of first nozzles 31 is multiple, that is, the number of first nozzles 31 can be two, three, four or more, and the multiple first nozzles 31 are arranged at intervals in the second direction. Similarly, the number of second nozzles 32 is also multiple, that is, the number of second nozzles 32 can be two, three, four or more, and the multiple second nozzles 32 are arranged at intervals in the second direction (e.g., in the second direction). Figure 2 The left and right directions are arranged alternately, with the first direction intersecting the second direction.

[0050] By setting up multiple first nozzles 31 and multiple second nozzles 32, it is possible to weld multiple pieces in the second direction, thereby saving welding time and effectively improving welding efficiency.

[0051] For example, such as Figure 1 and Figure 2As shown, there are two first nozzles 31, which are arranged alternately in the left and right directions. There are also two second nozzles 32, which are arranged alternately in the left and right directions.

[0052] According to some embodiments of this utility model, refer to Figure 2 and Figure 3 The busbar welding assembly 100 includes a dust collection pipe 60, with each dust collection pipe 60 corresponding to one of the nozzles 30. The dust collection pipe 60 is adapted to connect to the dust collection port 33 of the nozzle 30. During welding, a large amount of metal fumes and harmful gases are generated. These substances not only pose a threat to the health of operators but also affect the welding field of vision and reduce welding quality. Therefore, the dust collection pipe 60 effectively removes these fumes and gases, thereby ensuring welding quality and a safe working environment.

[0053] For example, such as Figure 2 and Figure 3 As shown, a dust removal port 33 is provided on the side wall of the nozzle 30, which penetrates the side wall of the nozzle 30, and the dust removal pipe 60 is connected to the dust removal port 33.

[0054] According to some embodiments of this utility model, refer to Figure 4 The driving component 40 is a cylinder. Therefore, the cylinder has a simple structure and low cost, making it easy to use in large quantities. At the same time, the cylinder is easy to operate, thus reducing production difficulty and effectively ensuring production efficiency.

[0055] Furthermore, such as Figure 4 As shown, the busbar welding assembly 100 includes a magnetic switch 73, which is connected to a cylinder. The magnetic switch 73 is used to control the stroke of the cylinder, thereby preventing the cylinder from becoming too long and causing the first mounting plate 21 to separate from the base plate 10.

[0056] According to a second aspect embodiment of the present invention, a busbar welding apparatus is described, with reference to... Figure 1 , Figure 2 and Figure 3 This includes the bus welding assembly 100 of the first aspect of this embodiment.

[0057] According to the embodiments of the present invention, the busbar welding device, by providing the busbar welding assembly 100 of the first aspect embodiment and providing the relatively movable nozzle 30, can save the time of disassembling the tooling, improve the welding efficiency, thereby ensuring production efficiency. At the same time, it can improve the versatility of the busbar welding assembly 100 and reduce the cost of use.
