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

[0021] Please refer to Figures 1-5, in the embodiment of the present utility model, a novel side wall welding device for large cylindrical batteries includes a working frame 1. On one side of the working frame 1, there is a first workbench 3. On one side of the first workbench 3, there is a limit frame 4. And on one side of the limit frame 4, there is a second workbench 5. Vertically driven on the top of the working frame 1 is a first moving frame 2. And obliquely driven on one side of the first moving frame 2 is a laser welder 7. And the laser welder 7 moves up and down on the side surface of the limit frame 4. Horizontally arranged on one side of the surface of the second workbench 5 is at least one set of motors 9. And horizontally driven on one side of the motor 9 is a coupling 11. Vertically arranged on one side of the coupling 11 is a pressing block 13. And locked on the other side of the pressing block 13 is a mounting table 15. And horizontally placed on one side of the mounting table 15 is a battery 18 to be welded. When the motor 9 drives the coupling 11 to rotate, the coupling 11 drives the pressing block 13 and the mounting table 15 to rotate together, thereby driving the battery 18 to rotate. The other end of the battery 18 penetrates through the limit frame 4, and the other end of the battery 18 rotates on one side inside the limit frame 4. And the rotation speed of the motor 9 is the same as the welding speed of the laser welder 7. Thus, after the laser welder 7 adjusts to the required height on the side of the limit frame 4 and remains stationary, at this time, the motor 9 drives the coupling 11 to rotate and drives the pressing block 13 and the mounting table 15 to rotate together, thereby driving the battery 18 to rotate on one side of the limit frame 4. And then the side wall of the rotating battery 18 is continuously welded by the laser welder 7, avoiding problems such as sequential pause welding during battery side wall welding, limited welding parts, the need to manually rotate the battery to adjust the welding parts, uneven welding, a more cumbersome process, a longer cycle, and lower efficiency.

[0022] Vertically arranged on the top of the limit frame 4 is a steering limit frame 17. Vertically arranged on both sides of the inner top of the steering limit frame 17 are limit posts 16. And the limit posts 16 are parallel to the limit frame 4. Between the limit frame 4 and the steering limit frame 17, there are rollers 19. And the rollers 19 are movably arranged on both sides of the limit frame 4. And the rollers 19 are parallel to the limit posts 16. Thus, when the battery 18 is horizontally placed on the limit frame 4, the battery 18 is placed between the rollers 19 and the battery 18 rolls between the rollers 19 and has rolling contact with the limit posts 16. Thereby, through the cooperation between the rollers 19 and the limit posts 16, the battery 18 is rollingly limited on the limit frame 4 to prevent the battery 18 from being displaced during the welding process.

[0023] A second moving frame 6 is provided between the first moving frame 2 and the laser welder 7. The second moving frame 6 is vertically located at the side of the first moving frame 2 and moves up and down on the side of the first moving frame 2. The laser welder 7 is obliquely located at the side of the second moving frame 6, and the laser welder 7 and the second moving frame 6 move in the same direction. The laser welder 7 moves along the side of the first moving frame 2 through the second moving frame 6 to facilitate welding of batteries 18 of different heights.

[0024] On the other side of the surface of the second workbench 5, a bearing fixing frame 14 is vertically provided. A bearing seat 12 is horizontally provided on the bearing fixing frame 14. The coupling 11 passes through the bearing seat 12 and rotates inside the bearing seat 12. The bearing seat 12 enables the motor 9 to drive the coupling 11 to rotate stably, so as to keep the battery 18 stable when rotating subsequently.

[0025] A motor fixing frame 10 is provided between the motor 9 and the second workbench 5. The motor fixing frame 10 is vertically provided on the second workbench 5, and the motors 9 are horizontally provided on both sides of the motor fixing frame 10. Thus, the motor 9 is fixed to the second workbench 5 through the motor fixing frame 10.

[0026] The first workbench 3 is provided with a welding limiting frame 8. The welding limiting frame 8 is vertically located at one side of the top of the first workbench 3. The welding limiting frame 8 is parallel to the limiting frame 4. The welding limiting frame 8 is located on one side of the laser welder 7. The battery 18 passes through the welding limiting frame 8, and one end of the battery 18 rotates inside the welding limiting frame 8. Thus, when the battery 18 rotates inside the welding limiting frame 8, the laser welder 7 can weld it evenly.

[0027] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
