Description

Technical Field

[0001] The utility model relates to the technical field of battery pack steel strips, in particular to a connecting block welding tool for battery pack steel strips. Background Art

[0002] Lithium batteries need to be bundled during transportation to prevent them from scattering, so battery strapping is needed. Battery strapping is usually a long steel strip enclosed to form a square structure. The head and tail ends of the steel strip are welded with a spot welding machine, and then the welded steel strip is directly put on the battery module. However, it is difficult to put on the battery module after welding. Therefore, the applicant has developed a new steel strip connection method, which is to weld a connecting block on the head and tail end of the steel strip respectively, and then set a through hole on the connecting block. After that, the head and tail connecting blocks of the steel strip can be connected to each other to lock the battery module in the steel strip.

[0003] The existing method of welding the connecting block is to first place the connecting block on the head end of the steel strip for welding. After the welding of the head end is completed, the connecting block is placed on the tail end of the steel strip for welding. Two welding operations are required to weld the connecting block to the head and tail ends of the steel strip. This welding method is not only inefficient but also labor-intensive. Therefore, there is an urgent need for a connecting block welding tool for battery pack steel strips that can not only improve welding efficiency but also reduce welding labor intensity. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a welding tool for connecting blocks of battery pack steel strips, which can not only improve welding efficiency but also reduce welding labor intensity.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a battery pack steel strip connection block welding tool, comprising:

[0006] base;

[0007] A limit block is detachably connected to the working base, and a first strip groove is provided on the opposite side of the Y direction at the lower end of the limit block near the tooling base. The first strip groove is used to place the head end of the steel belt, and a second strip groove is provided on the side of the Y direction at the lower end of the limit block near the tooling base. The second strip groove is used to place the tail end of the steel belt, and a first limiting groove is provided on the upper part of the first strip groove, and a second limiting groove is provided on the upper part of the second strip groove. The first limiting groove and the second limiting groove are used to place the connecting block;

[0008] Under the welding device, the head end of the steel strip is inserted from the Y-direction opposite side of the strip groove, and the tail end of the steel strip is inserted from the Y-direction side of the strip groove. Two connecting blocks are placed on the head end and tail end of the steel strip respectively, so that the bolt holes of the two connecting blocks are coaxial, and the two connecting blocks are respectively located in the first limiting groove and the second limiting groove;

[0009] Welding mechanism, the welding mechanism includes a welding block and a driving member. The welding block is located above the limiting block. The welding block is movably connected to the base in the vertical direction, and the driving member is used to drive the welding block to move.

[0010] Furthermore, the first limiting groove and the second limiting groove are U-shaped grooves.

[0011] Furthermore, the base is provided with a first through hole, and the limiting block is provided with a second through hole matching the first through hole. A bolt sequentially passes through the first through hole and the second through hole, and the limiting block is fixedly connected to the base with a nut.

[0012] Furthermore, the driving member is a cylinder. The cylinder block of the cylinder is connected to the base, the axial direction of the cylinder is the vertical direction, and the welding block is connected to the piston rod of the cylinder.

[0013] Furthermore, the shape of the limiting block is an "I"-shaped structure.

[0014] The beneficial effect of the present utility model is that: compared with the prior art, by setting the structure of the limiting block, the head end and the tail end of the steel strip can be welded only once, which can not only improve the welding efficiency but also reduce the welding labor intensity.
