Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery separator technology, and in particular to a wrinkle removal device for battery separator processing. Background Technology
[0002] In the structure of lithium batteries, the separator is one of the key inner components. Its main function is to separate the positive and negative electrodes to prevent short circuits caused by contact between the electrodes, while also allowing electrolyte ions to pass through. During the stretching and winding process, uneven tension or equipment precision issues can easily cause wrinkles in the battery separator. Wrinkles can lead to uneven separator thickness and abnormal micropore distribution, affecting the battery's safety and electrochemical performance.
[0003] Currently, traditional battery separator wrinkle removal equipment mostly employs roller wrinkle removal technology. This technology involves feeding the battery separator onto a fixed array of rollers, utilizing the mechanical force exerted on the separator as it travels between the rollers to remove wrinkles generated during transport. However, this traditional equipment has shortcomings: because the roller positions are fixed and cannot be adjusted, it is difficult to precisely control the tension between the rollers and the separator according to the actual transport status of the separator. This results in uneven stress on the separator, ultimately leading to low wrinkle removal efficiency and failing to meet the demands of high-precision production. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides a wrinkle removal device for battery separator processing, which aims to improve the problems in the prior art where the tension between the roller and the separator cannot be adjusted by moving the roller, and where the positioning mechanism cannot be dynamically adjusted according to the different widths of different battery separators during winding.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A wrinkle removal device for battery separator processing includes a base, two supports fixedly connected to the bottom of the base, a side plate one fixedly connected to the front top of the base, a motor one fixedly connected to the outer side of the side plate one, a winding roller fixedly connected to the output end of the motor one, a side plate two fixedly connected to the rear top of the base, a lifting assembly inside the side plate two, and a limit assembly inside the base. The lifting assembly includes a rotating rod rotatably connected inside the first side plate. A second motor is fixedly connected to the outer side of the first side plate. The output end of the second motor is fixedly connected to the middle of the rotating rod. Two gears are fixedly connected to the outer periphery of the rotating rod. Two racks are slidably connected inside the first side plate. The gears and racks are meshed together. A second leveling roller is rotatably connected to the side of the rack away from the gears. A slider is rotatably connected to the end of the second leveling roller away from the rack. A limit rod is slidably connected to the middle of the slider. As a further description of the above technical solution: The limiting assembly includes two electric push rods, which are fixedly connected inside the base. Two slide rails are fixedly connected to the inner wall of the base. A clamping plate is slidably connected to the top of each of the two slide rails. The output ends of the two electric push rods are fixedly connected to the outside of one of the clamping plates. A connecting rod is rotatably connected to the middle of each of the two clamping plates. A rotating plate is rotatably connected between the two connecting rods. The rotating plate is rotatably connected inside the base. A connecting block is fixedly connected to the top of the clamping plate. A limiting plate is fixedly connected to the top of the connecting block. As a further description of the above technical solution: Both sliders are slidably connected inside the second side plate, and both limiting rods are fixedly connected inside the second side plate; As a further description of the above technical solution: The side plate has two notches at the top, and the rack is slidably connected inside the notches; As a further description of the above technical solution: The rotating rod is rotatably connected inside the first side plate, and a leveling roller is rotatably connected between the first side plate and the second side plate; As a further description of the above technical solution: The side plate is internally fixedly connected to multiple slide rails, and a rack is slidably connected between two slide rails. As a further description of the above technical solution: Both connecting blocks are slidably connected inside the base, and both limiting plates are slidably connected to the top of the base; As a further description of the above technical solution: Both of the limiting plates are slidably connected to the outer periphery of the take-up roller, and the take-up roller is rotatably connected between the first side plate and the second side plate.
[0006] This utility model has the following beneficial effects: 1. In this utility model, the rotating rod is driven to rotate by starting the second motor. The two gears on the outer periphery of the rotating rod also rotate. Since the gears mesh with the rack, the rotation of the gears will drive the rack to move, which in turn will drive the second leveling roller to move. When the second leveling roller moves, the slider at its other end slides on the limiting rod. By adjusting the height difference between the first leveling roller and the second leveling roller, the tension between the battery separator and the first and second leveling rollers is adjusted, thereby ensuring that the separator is tightly attached to the first and second leveling rollers, thereby reducing the formation of wrinkles and avoiding wrinkles caused by local overstretching or loosening.
[0007] 2. In this invention, the electric push rod is activated to drive the clamping plate at its output end to slide along the slide rail, thereby driving the connecting rod connected to it to move. Since the other end of the connecting rod is rotatably connected to the rotating plate, the connecting rod will push the rotating plate to rotate, and the rotating plate will then push the connecting rod on the other side to move, thus driving the clamping plate on the other side to slide. At the same time, the connecting block at the top of the clamping plate drives the limiting plate to slide synchronously, realizing the dynamic adjustment of the distance between the two limiting plates according to the width of the battery separator, effectively reducing the occurrence of battery separator offset during winding, and ensuring the efficiency and stability of the winding operation.

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0011] Reference Figures 1-5An embodiment of this utility model provides a wrinkle removal device for battery separator processing, including a base 1, two supports 2 fixedly connected to the bottom of the base 1, a side plate 3 fixedly connected to the front top of the base 1, a motor 4 fixedly connected to the outer side of the side plate 3, a winding roller 5 fixedly connected to the output end of the motor 4, and by starting the motor 4, the output end of the motor 4 will drive the winding roller 5 to rotate, thereby winding, a side plate 23 fixedly connected to the rear top of the base 1, a lifting component is provided inside the side plate 23, and a limit component is provided inside the base 1; The lifting assembly includes a rotating rod 15, which is rotatably connected inside a side plate 3. A motor 6 is fixedly connected to the outside of the side plate 3. The output end of the motor 6 is fixedly connected to the middle of the rotating rod 15. Two gears 14 are fixedly connected to the outer periphery of the rotating rod 15. When the motor 6 is started, the output end of the motor 6 will drive the rotating rod 15 and the gears 14 on its outer periphery to rotate together. Two racks 13 are slidably connected inside the side plate 3. The gears 14 and racks 13 are meshed. Since the gears 14 and racks 13 are meshed, the rotation of the gears 14 will drive the racks 13 to move. A leveling roller 8 is rotatably connected to the side of the rack 13 away from the gears 14. A slider 10 is rotatably connected to the end of the leveling roller 8 away from the rack 13. A limit rod 9 is slidably connected to the middle of the slider 10. The movement of the racks 13 will drive the leveling roller 8 to move, thereby adjusting the tension between the battery separator and the leveling roller 8, avoiding excessive stretching or loosening that would cause wrinkles. Reference Figure 1 , Figure 3 and Figure 6 The limiting assembly includes two electric push rods 16, which are fixedly connected inside the base 1. Two slide rails 17 are fixedly connected to the inner wall of the base 1. A clamping plate 21 is slidably connected to the top of each slide rail 17. The output ends of the two electric push rods 16 are fixedly connected to the outside of one of the clamping plates 21. When the electric push rod 16 is activated, its output end will drive the clamping plate 21 to slide on the slide rail 17. A connecting rod 19 is rotatably connected to the middle of each clamping plate 21, and a rotating plate 18 is rotatably connected between the two connecting rods 19. When the clamping plate 21 slides... When the device moves, it will cause the connecting rod 19 connected to it to move together. The movement of the connecting rod 19 will cause the rotating plate 18 to rotate, thereby causing the rotating plate 18 to push the connecting rod 19 on the other side to move. In turn, the connecting rod 19 will push the clamping plate 21 on the other side to move. The rotating plate 18 is rotatably connected to the inside of the base 1. The top of the clamping plate 21 is fixedly connected to the connecting block 20. The top of the connecting block 20 is fixedly connected to the limiting plate 11. Through the connecting block 20, the limiting plate 11 can be driven to move together with the clamping plate 21, thereby adjusting the distance between the two limiting plates 11. Reference Figure 2Both sliders 10 are slidably connected inside the side plate 23, and the two limiting rods 9 are fixedly connected inside the side plate 23. When the sliders 10 are driven by external force, they will slide inside the side plate 23. Reference Figure 1 and Figure 4 The top of the side plate 3 has two notches 22, and the rack 13 is slidably connected inside the notches 22. By opening the notches 22, the rack 13 can move upward without any obstruction. Reference Figure 1 and Figure 5 The rotating rod 15 is rotatably connected inside the side plate 3. When the rotating rod 15 is driven to rotate, it will rotate inside the side plate 3. A leveling roller 7 is rotatably connected between the side plate 3 and the side plate 23. When the battery separator passes through the leveling roller 7, the friction between the battery separator and the leveling roller 7 will drive the leveling roller 7 to rotate, thereby conveying the battery separator. Reference Figure 4 The side plate 3 is fixedly connected to multiple slide rails 12. A rack 13 is slidably connected between two slide rails 12. When the rack 13 slides, it will slide between the two slide rails 12. Reference Figure 1 and Figure 6 Both connecting blocks 20 are slidably connected inside the base 1, and both limiting plates 11 are slidably connected to the top of the base 1. When the connecting blocks 20 slide inside the base 1, they will drive the limiting plates 11 to slide on the top of the base 1, thereby adjusting the distance between the two limiting plates 11. Reference Figure 1 and Figure 3 Both limiting plates 11 are slidably connected to the outer periphery of the winding roller 5. By adjusting the distance between the limiting plates 11, the winding deviation of the battery separator during winding is prevented. The winding roller 5 is rotatably connected between side plate 1 3 and side plate 23.
[0012] Working principle: First, start motor 6. Motor 6 will drive rotating rod 15 to rotate. Rotating rod 15 will drive two gears 14 on its outer circumference to rotate together. Since gear 14 meshes with rack 13, the rotation of gear 14 will drive rack 13 to move. Then, rack 13 will drive leveling roller 8 to move. After leveling roller 8 moves, its other end will also drive slider 10 to slide on the outer circumference of limit rod 9. Thus, by adjusting the height between leveling roller 7 and leveling roller 8, the tension between the battery separator and leveling roller 7 and leveling roller 8 can be adjusted, which helps to reduce the occurrence of wrinkles.
[0013] When the electric push rod 16 is activated, it causes the clamping plate 21 to slide on the slide rail 17. The slide rail 17 then moves the connecting rod 19 connected to it. Since the other end of the connecting rod 19 is rotatably connected to the rotating plate 18, the connecting rod 19 pushes the rotating plate 18 to rotate. The rotating plate 18 then pushes the connecting rod 19 on the other side to move, which in turn causes the clamping plate 21 on the other side to slide. Simultaneously, by fixing the connecting block 20 to the top of the clamping plate 21, the limiting plate 11 can slide along with the clamping plate 21. This allows the distance between the two limiting plates 11 to be dynamically adjusted according to the width of the battery separator during winding, preventing misalignment during winding.
[0014] 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.
