They ensure the stability and safety of the battery module during assembly, transportation, and use, and are mainly welded to the side plates, fixing points, and connecting pieces of the battery module.

[0003] Currently, the manufacturing process of battery modules typically requires the use of mounting equipment to secure them. However, the existing mounting equipment generally employs a fixed design, which poses a significant limitation as it is only suitable for battery modules of a specific size range, greatly restricting the equipment's versatility and flexibility. Furthermore, the efficient processing of graphite boats of various sizes necessitates cumbersome disassembly and assembly procedures, hindering the improvement and optimization of overall processing efficiency.

[0004] Therefore, based on the above problems, we designed a battery module end plate welding and installation equipment. Utility Model Content

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] like Figure 1 As shown, a battery module end plate welding and installation equipment includes a frame 2 and a welding and installation frame 4 rotatably disposed on the inner side of the frame 2.

[0023] Specifically, a DC servo motor 22 is connected to the side of the frame 2, and bearing seats 21 are connected to both sides of the top surface of the frame 2. A rotating column is rotatably installed in each bearing seat 21, and a flange plate 23 is connected to the end of each rotating column. The two sides of the welded mounting frame 4 are connected to the two flange plates 23.

[0024] like Figure 1 and Figure 2 As shown, it also includes: a pair of U-shaped clamping rods 11, which are respectively set on both sides of the inner wall of the welding mounting frame 4. A pair of miniature cylinders 1 are connected to the outside of the welding mounting frame 4. The rod of each miniature cylinder 1 passes through the welding mounting frame 4 and the back of each U-shaped clamping rod 11. Each U-shaped clamping rod 11 has a clamping notch 101 on its inner wall. The inner walls on both sides of each clamping notch 101 extend into the U-shaped clamping rod 11. A magnetic sheet 102 is built into the inner wall of each clamping notch 101.

[0025] Specifically, as a preferred embodiment, each clamping notch 101 is provided with a sleeve 12, and an adsorption magnetic plate 103 is connected to the back of the sleeve 12. Each sleeve 12 is adhered to the clamping notch 101 by the adsorption magnetic plate 103 on the back, and the ends are inserted into the extensions on both sides of the clamping notch 101. The sleeve 12 is easily fixed in the clamping notch 101 by the adsorption magnetic plate 103 on the back. The two ends of the sleeve 12 are inserted into the extension of the clamping notch 101, which simplifies the disassembly and assembly process and improves work efficiency.

[0026] like Figure 1 and Figure 3As shown, the implementation includes: a pair of module clamps 31, respectively disposed inside the welding mounting frame 4. Each module clamp 31 has a clamping groove 32 on its inner side. A pair of guide posts 3 are provided on the inner walls of both sides of the welding mounting frame 4. A return spring 33 is connected to the end of each guide post 3. A pair of mounting grooves 301 are provided on the side of each module clamp 31. Each guide post 3 and return spring 33 are inserted into the mounting groove 301. The other side of the return spring 33 is connected to the inner wall of the mounting groove 301. By pushing the module clamp 31 to slide along the guide post 3, the return spring 33 is compressed to store the rebound force, thereby tightly clamping both sides of the battery module within the module sleeve 34. The rebound force of the return spring 33 is used to pre-fix the battery module. At this time, the other two sides of the battery module protrude outside the module clamp 31. Subsequently, the end plate to be welded is properly placed in the clamp 12, ensuring that its top and bottom surfaces are exposed. Then, the micro cylinders 1 on both sides are activated to drive the U-shaped clamping rods 11 to press the end plate tightly against the side of the connecting piece of the battery module, which can realize the convenient clamping of the battery module.

[0027] Specifically, as a preferred embodiment, each clamping slot 32 has an installation socket 302 on its inner wall, and each clamping slot 32 is provided with a module sleeve 34. The back of each module sleeve 34 is provided with a card protrusion 303 at the position corresponding to each installation socket 302. A magnetic block 35 is connected to the end of each card protrusion 303 and inside the installation socket 302. By firmly embedding the module sleeve 34 into the clamping slot 32 and ensuring that the card protrusion 303 on the back is inserted into the installation socket 302, and by utilizing the mutual attraction between the magnetic block 35 at the end of the card protrusion 303 and the magnetic block 35 inside the installation socket 302, the module sleeve 34 can be quickly installed and removed.

[0028] like Figures 1 to 3 As shown in this embodiment, it should also be noted that before implementation, the installation equipment is placed on a machine tool and used in conjunction with welding equipment. Welding methods can include resistance welding, laser welding, and ultrasonic welding. This embodiment uses laser welding as an example. It should be noted that the battery module to be welded in this embodiment is a small battery module, consisting of multiple cells assembled into one unit, not a large one. Welding mainly involves the upper and lower surfaces. Before implementation, the model of the DC servo motor 22 is selected and the speed is set. This part is a commercially available product in the prior art, and its working principle has been disclosed. Furthermore, it should be noted that this application only addresses the shortcomings of existing welding installation equipment, which is only suitable for battery modules of a specific size range, greatly limiting the equipment's application breadth and flexibility. It improves upon the cumbersome disassembly and assembly process required for the effective processing of graphite boats of various specifications, hindering the improvement and optimization of overall processing efficiency. It does not involve other improvements. The working principle of this battery module end plate welding installation equipment is described below:

[0029] In use, the operator selects a suitable module sleeve 34 according to the specifications of the battery module, securely embeds it into the clamping slot 32, and ensures that the card protrusion 303 on the back is inserted into the mounting socket 302. Simultaneously, the mutual attraction between the magnetic block 35 at the end of the card protrusion 303 and the magnetic block 35 inside the mounting socket 302 enables quick installation and removal of the module sleeve 34. Next, a matching clamp 12 is selected according to the welding requirements. The clamp 12 is easily fixed in the clamping notch 101 by the magnetic plate 103 on the back. Both ends of the clamp 12 are inserted into the extension of the clamping notch 101, simplifying the assembly and disassembly process and improving work efficiency.

[0030] Next, the operator pushes the module clamp 31 to slide along the guide post 3, compressing the return spring 33 to store the rebound force, thereby tightly clamping both sides of the battery module into the module sleeve 34, using the rebound force of the return spring 33 to pre-fix the battery module. At this time, the other two sides of the battery module are exposed outside the module clamp 31. Then, the end plate to be welded is properly placed in the sleeve 12, ensuring that its top and bottom surfaces are exposed, and then the micro cylinders 1 on both sides are activated to drive the U-shaped clamping rods 11 to press the end plate tightly against the side of the connecting piece of the battery module.

[0031] Once the end plate and connecting piece are precisely aligned, the laser welding equipment on the machine tool welds the upper gap between the end plate and the connecting piece. After the upper welding is completed, the DC servo motor 22 is started to drive the rotating column, welding mounting frame 4, and the internal battery module and end plate to rotate to a predetermined angle, so that the unwelded bottom gap faces the welding equipment, and the bottom welding is completed again using laser welding technology, achieving double-sided welding.

[0032] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
