Description

Technical Field

[0002] A lithium battery is a battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. Existing lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries.

[0003] After lithium batteries are produced, multiple lithium batteries need to be connected together to form a lithium battery pack. Currently, workers manually place multiple lithium batteries together and make the multiple lithium batteries fit together, and the multiple lithium batteries must be on the same horizontal line. Then the workers use insulating glue to wrap and fix the lithium battery packs placed together. This method is time-consuming and labor-intensive. At the same time, the workers manually connect multiple lithium batteries together, which makes the lithium batteries prone to deviation and dislocation. Therefore, a clamp for lithium battery production is proposed to solve the above problems. Utility Model Content

[0023] One end of the moving block 6 is fixedly connected to a moving plate 9, one end of the moving plate 9 is provided with a mounting groove, a rotating tube 902 is rotatably connected in the mounting groove, a tooth 901 is fixedly connected to the surface of the rotating tube 902 (when the moving plate 9 and the tooth 901 move upward, the gear ring 1202 will not be driven to rotate), a limit plate 903 fixedly connected to the mounting groove is arranged above the tooth 901, and a coil spring is connected to the rotating tube 902 and one side of the storage groove (the coil spring can drive the rotating tube 902 and the tooth 901 to reset).

[0024] Furthermore, a telescopic assembly is provided in the moving block 6 (the conveying assembly can enable the hydraulic cylinder 8 to drive the moving block 6 and the moving plate 9 to continue to move downward), and the telescopic assembly includes a storage groove opened at the bottom end of the moving block 6, and a telescopic rod 601 is fixedly connected in the storage groove, one end of the telescopic rod 601 is fixedly connected to the top of the fixed block 7, and a spring is connected to the storage groove and the top of the fixed block 7.

[0025] It should be noted that: a tape winding assembly is arranged in the U-shaped placing table 2, and the tape winding assembly includes a pair of symmetrical fixed columns 201 fixedly connected to one end of the U-shaped placing table 2, a rotating ring 3 is placed above the fixed columns 201, and a sliding groove is provided at the bottom end of the rotating ring 3 which is slidably connected to the fixed column 201, and a linkage bevel gear 10 is fixedly connected to the bottom end of the rotating ring 3.

[0026] It is worth noting that: a pair of symmetrical discs 301 are arranged above the rotating ring 3, the lower disc 301 is fixedly connected to the top of the rotating ring 3, a winding roller 302 is rotatably connected between the symmetrical discs 301, a blade 303 is fixedly connected between the symmetrical discs 301 (the blade 303 cuts the insulating tape), a round tube 11 is fixedly connected to the top of the U-shaped placement table 2 (the insulating tape is connected between the winding roller 302 and the round tube 11), and a through hole is opened on one side of the U-shaped placement table 2;

[0029] When the utility model is in use: when multiple lithium batteries need to be assembled into a lithium battery pack, the staff will place the multiple lithium batteries horizontally in the U-shaped placement table 2, and then the staff will start the hydraulic cylinder 8, the hydraulic cylinder 8 will drive the moving block 6, the fixed block 7 and the trapezoidal push block 701 to move downward, and at the same time drive the moving plate 9 to move downward, when the trapezoidal push block 701 moves downward to contact with the lithium battery, it will push the lithium battery pack and clamp it, so that the multiple lithium batteries are on the same horizontal line;

[0030] Then the staff continues to drive the hydraulic cylinder 8 to drive the moving block 6 and the moving plate 9 to move downward. At this time, the teeth 901 in the moving plate 9 move downward to drive the gear ring 1202, the rotating shaft 12 and the driving bevel gear 1201 to rotate. The driving bevel gear 1201 rotates to drive the linkage bevel gear 10 to rotate. The linkage bevel gear 10 rotates to drive the rotating ring 3 to rotate, thereby driving the winding roller 302 and the blade 303 to rotate. The winding roller 302 rotates with the rotating ring 3, and the insulating tape on the winding roller 302 is wound around the surface of the lithium battery pack. Multiple lithium batteries are connected and fixed. After the insulating tape on the winding roller 302 is wrapped around the lithium battery pack, the blade 303 will cut the insulating tape between the winding roller 302 and the round tube 11. At this time, the staff drives the hydraulic cylinder 8 to drive the movable block 6 and the fixed block 7 to move up, and then the staff can take out the lithium battery pack in the U-shaped placement table 2. The above device does not require the staff to manually align the lithium batteries, and does not require the staff to manually wrap the insulating tape around the lithium batteries, which saves time and effort while avoiding deviation and dislocation of the lithium batteries.

[0031] When the lithium battery pack needs to be wound with insulating tape later, the staff can simply connect one end of the insulating tape on the winding roller 302 to the round tube 11 .
