[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] As shown in the Figures 1 - 5 drawing, a general adjustable module welding tooling includes a tooling plate 1, a plurality of fixtures 7 slidably connected to the tooling plate 1, wear-resistant sheets 5 respectively fixedly arranged on both sides of the tooling plate 1, and a plurality of positioning screws 4 for fixing the fixtures 7. The positioning screws 4 movably pass through the side of the tooling plate 1, and an aluminum busbar is fixedly connected to the fixture 7.

[0022] On the inner side of the tooling plate 1, a first rectangular hole 12 and a second rectangular hole 11 are arranged in parallel. On the inner sides of the first rectangular hole 12 and the second rectangular hole 11, a first slide rail 13 and a second slide rail 14 are arranged respectively. The first slide rail 13 and the second slide rail 14 are slidably connected to the fixture 7 respectively.

[0023] On both sides of the tooling plate 1, a first long slot 15 is arranged respectively. The first long slot 15 penetrates through the tooling plate 1 and the second slide rail 14 and is connected to the first rectangular hole 12 and the second rectangular hole 11 respectively. The positioning screw 4 slides through the first long slot 15.

[0024] The fixture 7 includes a first sliding block 2 and a second sliding block 3 which are slidably connected to the first slide rail 13 and the second slide rail 14 respectively. The first sliding block 2 and the second sliding block 3 are arranged oppositely. The inner sides of the first sliding block 2 and the second sliding block 3 are connected to the side parts of the aluminum busbar.

[0025] In the middle of the wear-resistant sheet 5, a second long slot 6 is arranged in a penetrating manner. The second long slot 6 is connected to the first long slot 15. The second long slot 6 is slidably connected to the positioning screw 4.

[0026] The positioning screw 4 is threadedly connected to the first sliding block 2 and the second sliding block 3 respectively.

[0027] The specific working process of the present utility model:

[0028] When the present utility model works, it is necessary to first fix the battery module to the workbench connected to the welding machine, and then use a caliper to measure the length of the aluminum busbar to be welded, and adjust the fixture 7 according to the measured length; when adjusting the fixture 7, first loosen the positioning screws 4 connected to the first sliding block 2 and the second sliding block 3 respectively, adjust the distance between the first sliding block 2 and the second sliding block 3 according to the measured length of the aluminum busbar and leave an appropriate margin. After adjustment, tighten the positioning screws 4 connected to the first sliding block 2 and the second sliding block 3 to fix the fixture 7.

[0029] Place the adjusted welding tooling on the battery module and fix it. Place the multiple aluminum busbars to be welded into the fixture 7 of the welding tooling respectively. After the operation is completed, the workbench will send the battery module, the welding tooling and the aluminum busbars into the welding machine for welding.

[0030] After welding is completed, the welding machine sends the battery module back to the workbench, and then removes the welding tooling from the battery module. At this time, the aluminum busbars have been welded to the battery module. Because a margin was left between the aluminum busbars and the fixture 7 when adjusting the fixture 7 before, the welding tooling can be directly removed without loosening the positioning screws 4. After removing the welding tooling, the welding of the battery module is completed. When welding the next group of battery modules, just repeat the above steps.

[0031] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
