[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 and Figure 2 , an embodiment provided by the utility model: a lithium ion battery winding device, comprising a bracket 1, a fixed column 2 is fixedly connected to one side of the inner wall of the bracket 1, a motor 8 is fixedly connected to one side of the inner wall of the fixed column 2, a screw rod 9 is fixedly connected to the output end of the motor 8, a telescopic rod 12 is threadedly connected to the outer wall of the screw rod 9, the telescopic rod 12 is slidably connected to the inside of the fixed column 2, a threaded column 10 is rotatably connected to one side of the inner wall of the telescopic rod 12, a circular array of limiting grooves 11 are opened on the outer wall of the screw rod 9, the threaded column 10 is slidably connected to the inside of the limiting groove 11, a telescopic rod 2 13 is threadedly connected to the outer wall of the threaded column 10, the telescopic rod 2 13 is slidably connected to the inside of the telescopic rod 12, an air pump 14 is fixedly connected to one side of the inner wall of the telescopic rod 2 13, an air expansion shaft 3 is fixedly connected to the output end of the air pump 14, a discharging assembly is arranged on one side of the inner wall of the bracket 1, the discharging assembly comprises a discharging box 4, and the outer wall of the discharging box 4 is fixedly connected to one side of the inner wall of the bracket 1;

[0024] Specifically, first, the battery housing is placed in the discharge box 4, and the discharge box 4 is designed with appropriate space and guide structure to ensure that the battery housing is stably positioned. Then, the motor 8 drives the screw rod 9 to rotate, and the rotation of the screw rod 9 will drive the telescopic rod 12 to slide out from the inside of the fixed column 2. The function of the fixed column 2 is to provide support and guidance to ensure the stable movement of the telescopic rod 12. As the screw rod 9 continues to rotate, the limit groove 11 on the screw rod 9 will drive the threaded column 10 to rotate synchronously. The design of the threaded column 10 has sufficient rigidity and wear resistance and can withstand high-intensity workload. When the threaded column 10 rotates, it will Drive the telescopic rod 12 and slide it out from the inside of the telescopic rod 1. At this time, the inflatable shaft 3 will be inserted into the battery casing. The air pump 14 will drive the inflatable shaft 3 to fix the battery casing. The function of the inflatable shaft 3 is to provide uniform air pressure so that the battery casing is tightly fixed on the inflatable shaft 3 to ensure stability during the winding process. In addition, the extended telescopic rod 12 and the telescopic rod 13 will prevent the battery casing in the discharge box 4 from falling. This design takes into account the safety of the battery casing and the continuity of operation. When the telescopic rod 12 and the telescopic rod 13 are retracted, the battery casing inside the discharge box 4 will continue to fall, thereby achieving continuous feeding.

[0025] Reference Figure 1 and Figure 3 A winding tube 5 is fixedly connected to one side of the bottom of the bracket 1, and a rotating tube 15 is rotatably connected inside the winding tube 5. A motor 18 is fixedly connected to one side of the bottom of the bracket 1, and a gear 19 is fixedly connected to the output end of the motor 18. A rack 16 is fixedly connected to one side of the outer wall of the rotating tube 15, and the rack 16 is meshed with the gear 19. A material unwinding roll 17 is rotatably connected to one side of the inner wall of the rotating tube 15;

[0026] Specifically, when the battery shell is transported to the inside of the winding tube 5 by the inflatable shaft 3, and the gear 19 is driven to rotate by the motor 18, the rotation of the gear 19 is transmitted to the rotating tube 15 through the rack 16, and the rotating tube 15 rotates inside the winding tube 5, so that the unwinding roll 17 can tightly wind up the battery shell on the inflatable shaft 3. This process requires precise mechanical coordination and precise control to ensure that the battery shell is evenly wound and will not be damaged.

[0027] Reference Figure 1 and Figure 4 A left-right symmetrical slide bar 6 is fixedly connected to one side of the bottom of the bracket 1, and a wedge-shaped slide plate 20 symmetrical up and down is slidably connected to the outer wall of the slide bar 6. A spring 21 is sleeved on the outer wall of the slide bar 6, and one end of the spring 21 is fixedly connected to one side of the outer wall of the wedge-shaped slide plate 20, and the other end of the spring 21 is fixedly connected to the outer wall of the slide bar 6. A collection box 7 is fixedly connected to one side of the inner wall of the bracket 1;

[0028] Specifically, the wound battery will be removed through a special device, which includes a wedge-shaped slide 20 and a spring 21. When the battery passes through the wedge-shaped slide 20, the inclined surface on the wedge-shaped slide 20 will overcome the force of the spring 21, so that the slide is pushed open, and then the battery will smoothly pass through the wedge-shaped slide 20. Once the battery passes through the slide, the force of the spring 21 will restore the wedge-shaped slide 20 to its original position and reclose the slide. In this process, the inflatable shaft 3 is responsible for fixing the battery in the appropriate position. When the inflatable shaft 3 needs to be retracted, it will release the battery due to the wedge-shaped slide 20, so that it can fall into the collection box 7, which is convenient for centralized processing or recycling.

[0029] Working principle: When the battery is wound, the battery shell can be placed in the discharge box 4, and then the motor 8 drives the screw rod 9 to rotate, so that the screw rod 9 drives the telescopic rod 12 to slide out of the fixed column 2, and then the limit groove 11 on the screw rod 9 drives the threaded column 10 to rotate synchronously, so that the threaded column 10 drives the telescopic rod 2 13 to slide out of the telescopic rod 1 12, and the air shaft 3 will be inserted into the battery shell, and the air pump 14 drives the air shaft 3 to fix the battery shell, and the extended telescopic rod 12 and telescopic rod 2 13 will prevent the battery shell in the discharge box 4 from falling, and when they are retracted, the battery shell in the discharge box 4 can continue to fall, so as to prevent the battery shell from falling. To achieve continuous feeding, the battery shell on the inflatable shaft 3 will be transported to the inside of the winding tube 5, and the motor 18 will drive the gear 19 to rotate. The gear 19 can drive the rotating tube 15 to rotate inside the winding tube 5 through the rack 16, and the battery shell on the inflatable shaft 3 can be wound by the unwinding roll 17. The wound battery will pass through the inclined surface on the wedge-shaped slide 20, overcome the force of the spring 21 to push the wedge-shaped slide 20 open, so that the battery passes through the wedge-shaped slide 20, and then the force of the spring 21 tightens the wedge-shaped slide 20, so that when the inflatable shaft 3 is retracted, the battery can be removed from the inflatable shaft 3 and fall into the collection box 7 for collection.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
