[0062] At present, when welding the battery module bar and the pole, a copper nozzle pressure plate is usually used to press the bar and the pole, and then laser welding is performed. In the traditional application mode, the copper nozzle pressure plate moves from top to bottom and performs a pressing action. In this operation mode, the copper nozzle pressure plate will cause a large range of obstruction on the top of the battery module, and the observation field of view is relatively poor; and the welding slag generated during the welding process will naturally fall on the welding part, which is easy to affect the subsequent welding operation and the molding quality of the product.

[0063] In view of the above technical problems, the present embodiment mainly provides a module welding auxiliary device, which can improve the welding quality between the busbar and the pole in the battery module.

[0064] like Figure 1-8 As shown, a module welding auxiliary device provided according to some embodiments of the present application includes a device frame 1, a copper nozzle pressure plate assembly 2 and a first driving mechanism 3. The copper nozzle pressure plate assembly 2 is arranged on the first driving mechanism 3, and can be used to press the bar piece on the pole during the welding operation of the battery module to facilitate the laser welding operation; the first driving mechanism 3 is arranged on the device frame 1, and can be used to drive the copper nozzle pressure plate assembly 2 to change its position in the horizontal direction and form a resisting force, so as to realize the pressing operation between the bar piece and the pole through the formed resisting force.

[0065] By setting up the first driving mechanism 3, the copper nozzle pressure plate assembly 2 can be controlled to change its position in the horizontal direction, and then a resisting force is formed, so that the tabs and poles are pressed tightly during the welding operation of the battery module; and this lateral resisting and fixing method can have a better observation field of view, which is convenient for operators to control the welding situation; moreover, the welding products generated during welding will not fall directly on the welding part, so the influence of welding slag on subsequent welding operations can be reduced, thereby improving the welding quality of the product.

[0066] As one application example, the copper nozzle pressure plate assembly includes a cover plate 21 and a plurality of copper nozzles 22, and the plurality of copper nozzles 22 are arranged on the cover plate 21; and a dust removal mechanism is connected to each of the copper nozzles 22.

[0068] In some embodiments, a baffle 221 is provided between two adjacent copper nozzles 22 or between the copper nozzles 22 of different layers arranged in an upper and lower layer to play an electrical protection role and improve safety performance.

[0069] In some embodiments, the dust removal mechanism includes a negative pressure generator, and the dust removal operation is achieved by generating negative pressure through the negative pressure generator.

[0070] By setting up the dust removal mechanism, the welding products in the copper nozzle 22 can be collected, including welding slag, smoke and plasma gas formed during welding; by timely absorbing the welding products, the impact of the welding products on subsequent welding operations can be further reduced.

[0071] As one application example, the dust removal mechanism further includes a plurality of dust collecting baffles 41 and dust extraction pipes 42.

[0073] In some embodiments, the dust collecting baffles 41 can be set to two or more. In this case, the dust collecting baffles 41 are set independently of each other. The plurality of copper nozzles 22 can be connected with the corresponding dust collecting baffles 41 according to the different areas where they are located or the different coverage areas of the dust collecting baffles 41 to achieve regional dust removal control.

[0074] In some embodiments, a single dust collecting baffle 41 may be connected to only one copper nozzle 22 , or may be connected to two or more copper nozzles 22 at the same time.

[0075] In some embodiments, a single dust collecting baffle plate 41 may be connected to only one dust extraction pipe 42 , or may be connected to two or more dust extraction pipes at the same time, so as to improve the uniformity of the negative pressure strength and the suction force.

[0076] The dust collecting baffle plate 41 can be connected to the copper nozzle 22 to absorb welding slag and the like in the copper nozzle 22 through the effect of negative pressure; at the same time, a corresponding area division relationship is formed between the dust collecting baffle plate 41 and the copper nozzle 22, so that the dust suction operation is more targeted, thereby facilitating the improvement of the dust removal effect on the copper nozzle 22 in the area.

[0077] As one application example, the dust removal mechanism also includes a collecting chamber 43, which is arranged between the dust collecting baffle 41 and the negative pressure generator.

[0083] In some embodiments, the pre-fixing member 231 is installed on the outer side of the end of the cover plate 21 , and the position of the adjusting member 232 on the pre-fixing member 231 is changed to drive the cover plate 21 to move closer to or away from the pre-fixing member 231 .

[0084] In some embodiments, the pre-fixing member 231 and the adjusting member 232 are respectively disposed on the outer sides of both ends of the cover plate 21. Figure 1 shown.

[0085] By providing the pre-fixing member 231 and the adjusting member 232 and connecting the adjusting member 232 to the cover plate 21 , the position of the cover plate 21 can be changed by changing the position of the adjusting member 232 on the pre-fixing member 231 , thereby realizing the position adjustment operation of the cover plate 21 .

[0086] As an example of one application, Figure 2 As shown, the adjusting member 232 and the pre-fixing member 231 can be arranged in the form of a threaded connection; the adjusting member 232 and the cover plate 21 can be arranged in the form of a snap-fit ​​connection, so that the adjusting member 232 can rotate relative to the cover plate 21.

[0087] In some embodiments, the adjusting member 232 can be configured as a screw structure, in which case one end of the adjusting member 232 is configured to face away from the cover plate 21 to serve as an adjusting portion 2321 , and the other end is clamped with the cover plate 21 .

[0088] In some embodiments, a slot 211 is provided on the cover plate 21 corresponding to the adjusting member 232, and along the thickness direction of the cover plate 21, the slot 21 is in a "T" shape, and the shape of one end of the adjusting member 232 connected to the cover plate 21 is adapted to the shape of the slot 211; when installed, the adjusting member 232 is embedded in the slot 211, such as Figure 2 shown.

[0089] By providing a threaded connection between the adjusting member 232 and the pre-fixing member 231 , it is possible to achieve fine adjustment of the position of the adjusting member 232 on the pre-fixing member 231 , thereby improving the accuracy of position adjustment.

[0090] As an example of one application, Figure 5 , 7 As shown, a plurality of positioning holes 212 are provided on the cover plate 21 , and adjustment holes 233 are provided on the mounting plate 23 corresponding to the positioning holes 212 , and the length of the adjustment hole 233 is greater than the diameter width of the positioning hole 212 .
