[0024] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In the battery production process in the related technology, in order to ensure the quality of the welding seam of the sealing nail, it is necessary to weld the sealing aluminum nails to make the metallographic first piece inspection before continuous production. The existing sealing nail welding first piece requires taking an aluminum shell and a top cover, pre-welding them into an empty shell battery cell, and then sealing and welding them with the aluminum nails. When making the metallographic after the sealing nail is welded, it is necessary to cut the aluminum shell and the top cover, and take the weld part for metallographic production. The aluminum shell only plays a supporting role in the welding process and does not participate in the welding of the sealing nail, but the aluminum shell can only be scrapped after metallographic cutting.

[0026] Therefore, in order to solve the technical problem of aluminum shell waste during metallographic production, it is urgent to design a battery sealing nail welding tool.

[0027] like Figure 1 As shown, at least one embodiment of the battery sealing nail welding tool comprises: a base 20; and a plurality of positioning blocks 30, which are respectively arranged around the upper opening edge of the base 20; and a top cover 10, which is detachably embedded in the upper opening of the base 20 through the positioning blocks 30. The top cover 10 is fixed to the base 20 through the positioning blocks 30 to form a contoured battery cell. Designing and manufacturing contoured batteries can not only save the time of pre-welding the top cover 10 and the aluminum shell to make an empty shell battery cell, but also save the consumption of the aluminum shell, thereby reducing costs and improving efficiency.

[0028] In some embodiments, a limiting cavity 23 for placing a battery cell is provided in the base 20. This arrangement is to achieve the same effect as an aluminum shell. The base 20 is used to replace the aluminum shell and is fixedly connected to the top cover 10 to produce a contoured battery cell.

[0029] In some embodiments, the bottom surface 22 and / or at least one side surface 21 of the base 20 is hollowed out, which can effectively reduce the weight of the base 20 and facilitate taking.

[0030] In some embodiments, in order to accurately fix the top cover 10 on the base 20, a positioning groove 33 for limiting the top cover 10 is opened on the positioning block 30. After the top cover 10 is placed on the positioning groove 33, the center of the top cover 10 coincides with the center of the base 20.

[0031] In some embodiments, the upper surface of the positioning block 30 is higher than the upper surface of the top cover 10 by no more than 0.5 mm. The top cover 10 is just embedded in the upper opening of the base 20 through the positioning block 30, and the positioning block 30 does not rise too much and interfere with the welding mechanism.

[0032] In some embodiments, the positioning block 30 is provided with a mounting hole 31 for fixedly connecting the base 20, and the mounting hole 31 is penetrated with a mounting pin 32 for fixing the positioning block 30. The positioning block 30 is fixedly connected to the base 20 by the mounting pin 32 penetrated in the mounting hole 31.

[0033] In some embodiments, the top cover 10 is provided with a positive electrode post 11 and a negative electrode post 13 for connecting the battery cell, and the positive electrode post 11 and the negative electrode post 13 are used to connect the battery.

[0034] In some embodiments, in order to completely isolate the interior of the battery from the external environment, the top cover 10 is provided with a welding port 12 for welding and sealing aluminum nails, and the welding port 12 is used for sealing and welding aluminum nails.

[0035] Some embodiments further provide a testing system, including: a battery sealing nail welding tool; and a welding device, which is movably arranged above the sealing aluminum nail welding port 12. After the welding device places the top cover 10, it can automatically place the aluminum nail for welding, and after welding, the top cover 10 is taken out for metallographic cutting.

[0036] In some embodiments, in order to fix the base 20, a clamp is provided on the outside of the base 20, and the base 20 can be reused, so that the metallographic structure of the sealing nail weld can be produced only by welding the top cover 10 and the aluminum nail.
