Description

Technical Field

[0001] This utility model relates to the field of lithium battery processing, and in particular to an adjustable winding machine for lithium battery production. Background Technology

[0002] Winding machines play a vital role in lithium battery processing, improving production efficiency, ensuring battery performance, reducing production costs, adapting to various battery shapes, and enhancing safety. They are an indispensable key piece of equipment in the lithium battery manufacturing process. In the lithium battery processing, winding machines are mainly used to wind positive electrode sheets, negative electrode sheets, and separators. The winding machine winds aluminum foil coated with positive electrode material, copper foil coated with negative electrode material, and separator paper in the middle into a cell structure in a certain order and manner.

[0003] A search revealed that Chinese Patent Publication No. CN221327815U discloses a positive and negative electrode winding machine for lithium battery production. The machine utilizes the elasticity of a spring-loaded suction pipe, which extends and retracts along with a pressing frame. This allows the spring-loaded suction pipe to extract dust from the upper surface of the electrode through the upper suction box, while the suction connecting pipe extracts dust from the lower surface of the electrode through the lower suction box. This design avoids the potential problem of electrode entanglement caused by dust particles on some electrode surfaces.

[0004] In the above technical solution, the dust particles on the surface of the electrode are sucked up by the cooperation of the spring suction pipe and the moving frame to avoid the hidden dangers of winding. However, before the separator paper is wound, it needs to be put on the winding roller of the winding machine. The winding roller cannot adapt to the separator paper rolls of different sizes, and the separator paper lacks preheating and guiding functions before winding, which will reduce the adhesion between the separator paper and the electrode, thereby reducing the winding effect. Therefore, an adjustable winding machine for lithium battery production is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides an adjustable winding machine for lithium battery production, which aims to improve the problem that the existing adjustable winding machines for lithium battery production lack the function of preheating and guiding the separator paper before winding, resulting in a reduction in winding effect.

[0013] As a further description of the above technical solution:

[0014] The adjustment component includes a groove, a dial ring is rotatably connected to the inner wall of the groove, a screw is fixedly connected to the bottom end of the dial ring, and a moving block is threadedly connected to the outer wall of the screw.

[0015] As a further description of the above technical solution:

[0016] A magnetic ring is fixedly connected to the side wall of the fixed disk, and a magnetic ring is fixedly connected to the end of the placement cylinder.

[0017] As a further description of the above technical solution:

[0018] The mounting plate has a movable groove on its side wall, and a movable seat is slidably connected to the inner wall of the movable groove. A support rod is fixedly connected to the bottom of the fixed plate.

[0019] As a further description of the above technical solution:

The discs are easily connected to the fixed disk 3 via the spring 4. A protrusion 6 is fixedly connected to the end of the winding roller 2, and a baffle 7 is sleeved on the outer wall of the winding roller 2. A groove 8 is opened on the inner surface of the baffle 7. Each set of winding rollers 2... Three sets of baffles 7 are provided on the surface of the baffles 7 and are distributed at equal distances. When the slot 8 is aligned with the protrusion 6, the baffles 7 can be fitted onto the winding roller 2. The outer wall of the winding machine body 1 is fixedly connected to the mounting plate 9. The outer wall of the mounting plate 9 is rotatably connected to the shaping roller 10. The inner wall of the shaping roller 10 is fixedly connected to the heating tube 11. There are two sets of shaping rollers 10, which are mirror images of each other with the center point of the winding roller 2 as the axis of symmetry. When the heating tube 11 is turned on, it can transmit heat to the shaping roller 10. The side wall of the mounting plate 9 is provided with guide rollers 12. There are two sets of guide rollers 12. The surface of the mounting plate 9 is provided with monitoring components and adjustment components.

[0033] Reference Figures 3-5 Spring 4 is sleeved on the outer wall of the winding roller 2, and placement cylinder 5 is sleeved on the outer wall of the winding roller 2. The inner wall of the groove 8 is adapted to the outer wall of the protrusion 6. The monitoring component includes a fixing plate 13. A temperature sensor 14 is fixedly connected to the top of the fixing plate 13. The sensing probe of the temperature sensor 14 is located on the side opposite to the shaping roller 10 and the guide roller 12. The adjustment component includes a groove 15. The groove 15 is opened on the outer wall of the mounting plate 9 to provide an installation position for the screw 17. A dial ring 16 is rotatably connected to the inner wall of the groove 15. The bottom end of the dial ring 16 is fixedly connected to the screw 17. A moving block 18 is threadedly connected to the outer wall of the screw 17. The outer wall of the moving block 18 is rotatably connected to the end of the first set of guide rollers 12. A magnetic ring 22 is fixedly connected to the side wall of the fixing plate 3. A magnetic ring 23 is fixedly connected to the end of the placement cylinder 5. The magnetic repulsive magnetism is present at the ends of the magnetic rings 22 and 23 that are close to each other.

[0034] Reference Figure 5The side wall of the mounting plate 9 is provided with a movable groove 20, and the inner wall of the movable groove 20 is slidably connected to a movable seat 21. The bottom of the fixed plate 13 is fixedly connected to a support rod 19, and the end of the support rod 19 away from the fixed plate 13 is fixedly connected to the outer wall of the movable block 18.

[0035] Working principle: Press the placement cylinder 5 inward, compressing the spring 4 and causing it to contract. At this time, the front end of the placement cylinder 5 is not in contact with the baffle 7. Then rotate the baffle 7 so that the protrusion 6 and the groove 8 are aligned. Remove the baffle 7 from the winding roller 2. Place the roll containing the diaphragm paper onto the placement cylinder 5. Press the placement cylinder 5 inward again. After the baffle 7 is placed onto the winding roller 2, the positions of each set of protrusions 6 and grooves 8 are not aligned. 5. After the operator's pressure is removed, the spring 4 returns to its elastic state. Combined with the repulsive force between magnetic ring 1 22 and magnetic ring 23, the placing cylinder 5 presses against the baffle 7 to prevent displacement. The diaphragm paper is pulled out so that its end passes through the two sets of shaping rollers 10, then through the first set of guide rollers 12, and then through the lower surface of the second set of guide rollers 12, until it is fixed on the winding frame on the winding machine body 1. When the winding frame winds the diaphragm paper, the diaphragm paper follows the two sets of shaping rollers 10 and the two sets of guide rollers 23. As the guide rollers 12 move, the two sets of heating tubes 11 are in the open state. The heating tubes 11 transfer heat to the surface of the two sets of shaping rollers 10, preheating the diaphragm paper and reducing wrinkles. At the same time, the preheated diaphragm paper can fit the electrode sheet better, reducing the gap between the diaphragm and the electrode sheet. During the preheating process, the temperature sensor 14 monitors the temperature of the diaphragm surface in real time to avoid the temperature being too high or too low. When the temperature is not suitable, the temperature sensor 14 sends the monitoring data to the PLC control terminal to remind the operator. Then, the heating temperature of the heating tubes 11 is finely adjusted. The dial ring 16 is manually turned to make the screw 17 drive the moving block 18 to rise and fall. At the same time, the support rod 19 drives the moving seat 21 to rise and fall inside the moving groove 20, so that the temperature sensor 14 moves with the first set of guide rollers 12, ensuring that the tension of the diaphragm paper can be adjusted while monitoring the temperature.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
