A gear 13 is fixedly installed on the side of the end of the connecting shaft 11 away from the rotating roller 3, and the two gears 13 on the same side are meshed with each other. A second transmission wheel 12 adapted to the first transmission wheel 10 is also fixedly installed on the side of one connecting shaft 11, and a transmission belt 21 for transmission is sleeved between the sides of the first transmission wheel 10 and the second transmission wheel 12. The ends of several connecting shafts 11 are fixedly connected to a limiting block 25, and the gear 13 is sleeved on the side of the limiting block 25. The end of the limiting block 25 away from the connecting shaft 11 is fixedly connected with a threaded column 26, and the side of the threaded column 26 is threadedly connected with a second limiting nut 27, and the side of the rotating roller 3 is fixedly connected with an anti-deflection ring 28, and the anti-deflection ring 28 is adapted to the conveyor belt 4.

[0030] Specific implementation method in this embodiment: the overall device is installed in the middle position of the two conveyor belts, the battery cells are placed on the conveyor belts for transmission, and the second drive motor 9 is started at the same time. The output end of the second drive motor 9 drives the first transmission wheel 10 to rotate, and the first transmission wheel 10 drives the second transmission wheel 12 to rotate through the transmission belt 21. The second transmission wheel 12 drives one of the connecting shafts 11 to rotate, and the connecting shaft 11 drives the corresponding rotating roller 3 to rotate. At the same time, the corresponding rotating roller 3 is driven to rotate through two mutually meshing gears 13. The two conveyor belts 4 rotate in opposite directions, and the battery cells on the conveyor belts are transported to between the two groups of conveyor belts 4, and the rotating roller 3 has elasticity to be able to move the battery cells between the two groups. The battery cells between the conveyor belts 4 are pressed tightly. When the battery cells are completely transferred to between the two conveyor belts 4, the second drive motor 9 is stopped and the first drive motor 6 is started. The output end of the first drive motor 6 drives the two support plates 2 to rotate half a circle in the two supporting plates 1 to flip the battery cells. The second drive motor 9 is started again and the second drive motor 9 drives the conveyor belt 4 to rotate again to transfer the battery cells on the two conveyor belts 4 to the conveyor belt on the other side to complete the flipping of the battery cells. The flipped battery cells are transported to the stringing machine position by the conveyor belt for welding. The flipping of the battery cells is completed during the transportation process without manual operation, thereby improving the welding efficiency of the battery cells through the stringing machine.

[0031] It is worth mentioning that the length of the above-mentioned conveyor belt 4 can be determined according to the site. It can flip one battery cell or multiple battery cells at the same time.

[0035] Specific implementation method in this embodiment: when it is necessary to adjust the distance between the two groups of conveyor belts 4, by rotating the adjusting bolt 17, the adjusting bolt 17 drives the moving seat 16 to move in the moving groove 24 and the through groove 15, and when the moving seat 16 moves, it drives the rotating ring 14 to move, and then the position of the connecting shaft 11 is adjusted to achieve the effect of adjusting the distance between the two groups of conveyor belts 4. After adjustment, tighten the first limit nut 18 threadedly connected to the side of the adjusting bolt 17 to fix the positions of the two conveyor belts 4.

[0036] It should be noted that after adjusting the spacing between the two groups of conveyor belts 4, the height of the supporting plate 1 needs to be adjusted and then re-fixed and installed to ensure that the two groups of conveyor belts 4 are matched with the conveyor belts on both sides.

[0037] Implementation Three

[0039] Specific implementation method in this embodiment: when it is necessary to adjust the distance between the two support plates 2, loosen the limit bolt 23, and the rotating rollers 3 on both sides move along the direction of the plug-in shaft 19 through the plug-in groove 20. After the positions of the two support plates 2 are adjusted, tighten the limit bolt 23 located in the installation groove 22. One end of the limit bolt 23 is tightly against the side of the plug-in shaft 19, thereby limiting and fixing the positions of the two rotating rollers 3. The cross-section of the plug-in shaft 19 is polygonal, which improves the rotation synchronization of the two rotating rollers 3 located at both ends of the plug-in shaft 19 and prevents the rotating rollers 3 from slipping.
