Technical Field

[0001] This utility model relates to the field of busbar welding technology, specifically a clamping device for welding busbars of cylindrical battery modules. Background Technology

[0002] During busbar welding, the busbar needs to be welded to the module terminal. Before welding, the welding surface is usually fixed on a horizontal plane so that the busbar can fit snugly against the module terminal. When welding the side of the busbar, the position of the busbar needs to be moved to different welding positions, which cannot meet the requirements of online welding and results in low welding efficiency.

[0003] To address the aforementioned issues, a utility model patent with authorization announcement number CN220006591U discloses a welding process. This device moves a copper busbar assembly along the first direction of the conveyor line during the welding process using several welding pressure mechanisms, enabling online welding of different positions of the workpiece without moving it, thereby improving welding efficiency.

[0004] However, in actual use, different types of clamping nozzles may be required for different battery modules, and the device cannot be well adapted to the clamping work of welding different battery modules. Utility Model Content

The movable module is mounted on the frame and is used to drive the lifting module to move. The movable end of the movable module is fixedly connected to a lifting base plate on which the lifting module is mounted via a lifting connecting seat. The telescopic end of the lifting module passes through the lifting base plate and is fixed with a lifting frame. A lifting mounting seat is installed at the lower end of the lifting frame. A clamping assembly is installed on the front and rear sides of the lifting mounting seat and is used to clamp the battery module from both the front and rear ends. A detection assembly is set on the front and rear sides of the frame and is used to detect the position of the clamping assembly.

[0007] As a preferred embodiment, the clamping assembly includes a clamping screw rotatably mounted on a lifting mounting base. The lifting mounting base is also equipped with a clamping servo motor for driving the clamping screw to rotate. A screw nut seat is threaded onto the clamping screw. A clamping frame is slidably mounted on the lower end of the lifting mounting base. The clamping frame is fixedly connected to the screw nut seat via a clamping connecting seat. Clamping nozzles can be detachably installed on opposite sides of the clamping frames on both the front and rear sides.

[0008] As a preferred option, each clamping frame can be equipped with multiple sets of clamping nozzles of different models.

The movable end of the movable module 2 is fixedly connected to the lifting seat plate on which the lifting module 3 is mounted via a lifting connecting seat 21. The telescopic end of the lifting module 3 passes through the lifting seat plate and is fixed with a lifting frame 32. A lifting mounting seat 33 is mounted on the lower end of the lifting frame 32. A clamping assembly 5 is mounted on the front and rear sides of the lifting mounting seat 33 and is used to clamp the battery module 62 from both the front and rear ends. A detection assembly 4 is set on the front and rear sides of the frame 1 and is used to detect the position of the clamping assembly 5. In this embodiment, the lifting module 3 can specifically be an SNL bevel gear lift. Each clamping frame 55 of the clamping assembly can be equipped with multiple sets of clamping nozzles 56 of different models. It also includes a conveying module, on which a placement tray 6 is mounted, and a battery rack 61 for placing the battery module 62 is provided.

[0017] The working principle of this utility model is as follows: The placement tray 6 containing the battery module 62 is transported to the bottom of the frame by the conveying module. Then, the height of the clamping component 5 is adjusted by the lifting module 3. After the adjustment is completed, the lifting module 3 is moved by the moving module 2 to adjust the position of the clamping component, thereby moving the appropriate clamping nozzle 56 to the front and rear sides of the battery module 62. The positioning status of the clamping component 5 can be determined by the detection component 4. Then, the busbar is clamped by the clamping component 5, and welding can be performed. The operation is simple and convenient for fixing the busbars of different models of battery modules 62, which can expand the application range of the device and better meet the needs of use.

[0018] As a further embodiment, the clamping assembly 5 includes a clamping screw 52 rotatably mounted on a lifting mounting base 33.

In this embodiment, to facilitate subsequent welding, the clamping nozzles 56 are provided with welding through holes 561.

[0019] The working principle of clamping assembly 5 is as follows: When clamping, clamping servo motor 51 is started, which drives clamping screw 52 to rotate, thereby driving screw nut seat 53 to rotate, which in turn drives clamping frame 55 to move through clamping connecting seat 54, so that clamping nozzle 56 is close to battery module 62, thereby clamping busbar and facilitating welding work.
