Description

Technical Field

[0001] This invention relates to the field of winding apparatus, and more particularly to a solid-state battery recycling winding apparatus. Background Technology

[0002] In existing battery recycling technologies, the separation and recycling of positive electrode plates, negative electrode plates, and intermediate films often employs simple manual peeling or mechanical tearing methods.

[0003] Currently, most winding structures are asynchronously designed, and the distance between the winding and separation positions lacks precise control. Often, multiple winding components are randomly arranged, making it difficult to ensure that the material can be wound in an orderly and stable manner after separation. As a result, the material is subjected to uneven tension due to the asynchronous nature of the winding components and the unequal distance between the winding and separation positions, causing stretching, damage, or wrinkling, thus reducing the material's recycling rate and reuse value. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies where materials are subjected to uneven tension, and to propose a solid-state battery recycling winding device.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a solid-state battery recycling and winding device, comprising a frame, wherein an arc-shaped rod is provided at the top of the frame, characterized in that it further comprises: A placement compartment, which is fixed to the frame; A rotating seat, comprising multiple rotating seats, each fixed on an arc-shaped rod, and a rotating shaft rotatably connected to the rotating seat; A take-up roller, wherein the take-up roller and the corresponding rotating shaft are fixed by a connecting assembly; Two positioning rollers are positioned above the placement compartment and are rotatably connected to the frame. A positioning gap is provided between the two positioning rollers and is located at the center of the arc-shaped rod. A synchronous drive assembly is mounted on the frame and is used to drive multiple take-up rollers to rotate synchronously.

[0006] Specifically, in conventional batteries, a thin film is sandwiched between the positive and negative electrode sheets. In this case, when the electrode sheet and the film thickness are the same, three take-up rollers can be set. During the recycling process, the battery is placed in the placement chamber, and the positive electrode sheet, film, and negative electrode sheet are passed through the positioning gap. The positioning rollers limit the electrode sheets on both sides, so that the positive electrode sheet, film, and negative electrode sheet are separated only after passing through the positioning gap. Then, the separated positive and negative electrode sheets are wound onto the two take-up rollers on both sides, and the film is wound onto the take-up roller in the middle. It should be noted that the rotating seats of the take-up rollers are all fixed on the arc-shaped rod, and the positioning gap is set at the center of the arc-shaped rod. This layout ensures that the distance from each take-up position to the separation position is strictly equal, and is equal to the radius of the arc-shaped rod. This equidistant design, together with the synchronous drive assembly to drive multiple take-up rollers to rotate synchronously, can ensure that the positive electrode sheet, film and negative electrode sheet maintain a consistent take-up speed and tension during the recycling process. This effectively avoids problems such as material stretching, breakage or wrinkling caused by asynchronous take-up, and significantly improves the stability of the recycling process and the material recycling rate.

This equidistant design, combined with the synchronous drive assembly driving multiple take-up rollers to rotate synchronously, ensures that the positive electrode, film, and negative electrode maintain a consistent take-up speed and tension throughout the recycling process.

[0027] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0028] like Figures 1 to 8 The solid-state battery recycling and winding device shown includes a frame 1, an arc-shaped rod 2 on the top of the frame 1, and further includes: Placement compartment 3 is fixed on frame 1; Rotary seat 4, there are multiple rotating seats 4, each of which is fixed on the arc-shaped rod 2, and a rotating shaft 5 is rotatably connected to the rotating seat 4; The take-up roller 6 is fixed to the corresponding rotating shaft 5 by a connecting assembly; Two positioning rollers 7 are positioned above the placement chamber 3. The positioning rollers 7 are rotatably connected to the frame 1. There is a positioning gap between the two positioning rollers 7, and the positioning gap is set at the center of the arc rod 2. The synchronous drive assembly is mounted on the frame 1 and is used to drive multiple take-up rollers 6 to rotate synchronously.

[0029] Specifically, in existing battery recycling technologies, the separation and recycling of positive electrode sheets, negative electrode sheets, and intermediate films often employs simple manual peeling or mechanical tearing methods. The winding structure is mostly asynchronous, and the distance between the winding position and the separation position lacks precise control. Often, multiple winding components are randomly arranged, making it difficult to ensure that the material can be wound in an orderly and stable manner after separation. As a result, the material is subjected to uneven tension due to the asynchronous nature of the winding components and the unequal distance between the winding position and the separation position, causing stretching, damage or wrinkling, reducing the material's recycling rate and reuse value. In order to solve the above problems, the present invention proposes the following working method: In conventional batteries, a thin film is sandwiched between the positive and negative electrode sheets. In this case, when the electrode sheet and the film thickness are the same, three winding rollers 6 can be set. During the recycling process, the battery is placed in the placement chamber 3, and the positive electrode sheet, film and negative electrode sheet are passed through the positioning gap. The positioning rollers 7 limit the electrodes on both sides, so that the positive electrode sheet, film and negative electrode sheet are separated only after passing through the positioning gap. Then, the separated positive electrode sheet and negative electrode sheet are wound on the two winding rollers 6 on both sides respectively, and the film is wound on the winding roller 6 in the middle. It should be noted that the rotating seats 4 of the take-up rollers 6 are all fixed on the arc-shaped rods 2, and the positioning gap is set at the center of the arc-shaped rods 2. This layout ensures that the distance from each take-up position to the separation position is strictly equal, and is equal to the radius of the arc-shaped rods 2. This equidistant design, together with the synchronous drive assembly to drive multiple take-up rollers 6 to rotate synchronously, can ensure that the positive electrode sheet, film and negative electrode sheet maintain a consistent take-up speed and tension during the recycling process. This effectively avoids problems such as material stretching, breakage or wrinkling caused by asynchronous take-up, and significantly improves the stability of the recycling process and the material recycling rate.

[0030] As a further embodiment of the present invention, the synchronous drive assembly includes a mounting base 8, which is fixed on the frame 1. A drive motor 9 is fixed on the mounting base 8. A first synchronous pulley 10 is fixed on the output shaft of the drive motor 9. A second synchronous pulley 11 is coaxially fixed on the take-up roller 6. A synchronous belt 12 is sleeved on both the first synchronous pulley 10 and the second synchronous pulley 11.

[0031] Specifically, by starting the drive motor 9, the drive motor 9 drives the first synchronous pulley 10 connected to it to rotate. Under the transmission action of the synchronous belt 12, it can drive the other second synchronous pulleys 11 to rotate synchronously, thereby making each take-up roller 6 rotate synchronously.

[0032] As a further embodiment of the present invention, a slide rail 13 is fixed on the frame 1, a slider 14 is slidably connected inside the slide rail 13, a push roller 15 is rotatably connected to the surface of the slider 14, an electric push rod 16 is fixed on the inner wall of the slide rail 13, a push block 17 is fixed at the end of the movable rod of the electric push rod 16, a pressure sensor 18 is fixed on the surface of the push block 17, and a first spring 19 is fixed between the pressure sensor 18 and the slider 14.

[0033] Specifically, in some cases, the electrode and the film have different thicknesses, with the film being thinner and the electrode being thicker. During winding, the circumferential diameter of the electrode will increase faster due to the cumulative thickness, while the circumferential diameter of the film will increase relatively slowly. The outer diameter of the electrode winding roller 6 gradually becomes larger than that of the film winding roller 6. If the rotation speeds of the two winding rollers 6 are kept consistent, according to the linear velocity formula, the winding linear speed of the electrode will be faster due to its larger radius, while the winding speed of the film will be slower due to its smaller radius. When the thickness difference between the electrode and the film is small, or the total winding length of both is short, this invention provides a push roller 15 along the film winding path. The roller surface of the push roller 15 is in contact with the material surface. Under normal winding conditions, both the electrode and the film are taut. At this time, the reaction force of the material on the push roller 15 compresses the first spring 19, causing the push roller 15 to be in a yielding state, ensuring a smooth winding process. When the difference in winding diameter causes a certain material, such as the film, to lag in winding speed, the material will become locally loose due to the lag. In this case, the elastic force of the first spring 19 will push the push roller 15 towards the material, forcing the loose material to bend appropriately. This bending structure can rebalance the tension between the electrode and the film at the separation position through the tension transmission of the material itself, avoiding material damage caused by tension differences, thereby ensuring the stress stability of both during the winding process. Furthermore, as the winding process continues, the slack in the film caused by the lag in winding speed will gradually accumulate. If only the elastic adjustment of the first spring 19 is relied upon, the supporting force may weaken due to the spring deformation limit, making it difficult to maintain stable support for the slack film. To address this, the present invention adds an active adjustment mechanism driven by an electric push rod 16: the cylinder of the electric push rod 16 is fixed inside the slide rail 13, and its push rod end is fixed to the push block 17, which is slidably connected inside the slide rail 13. When the slack in the film exceeds a preset threshold, for example, a pressure sensor 18 can be set between the first spring 19 and the push block 17 to detect the pressure feedback of the first spring 19. When the pressure value exceeds the preset threshold, the electric push rod 16 receives a control signal and extends its push rod. This causes the pusher block 17 to move within the slide rail 13. The pusher block 17 then moves the first spring 19 and the slider 14, thereby adjusting the position of the take-up roller 6. This adjustment method can dynamically change the pushing distance of the take-up roller 6 according to the degree of film slack. When the slack is small, the electric pusher rod 16 extends slightly, and the take-up roller 6 moves forward slightly through the slight compression of the spring, maintaining light support. When the slack increases significantly, the electric pusher rod 16 continues to extend, pushing the take-up roller 6 closer to the film until the roller surface of the take-up roller 6 forms a moderate contact pressure with the slack part of the film. This avoids damage caused by the rigid compression of the film by the take-up roller 6, and always maintains a stable support force on the film, ensuring that the slack part is evenly lifted and gradually wound into the take-up roller 6, maintaining the smoothness of the winding process.

[0034] As a further embodiment of the present invention, a connecting frame 20 is fixed on the rotating seat 4, and the end of the connecting frame 20 is sleeved on the take-up roller 6. The connecting assembly includes a mounting groove 21, which is opened at the end of the take-up roller 6. An electromagnet 22 is fixed in the mounting groove 21, and a sliding plate 23 is vertically slidably connected in the mounting groove 21. A second spring 24 is fixed between the sliding plate 23 and the electromagnet 22. The sliding plate 23 is made of ferromagnetic material, and a push plate 25 is horizontally slidably connected to the bottom of the sliding plate 23. A first elastic block 26 is fixed on the bottom surface of the push plate 25.

[0035] Specifically, when the thickness difference between the electrode and the film increases significantly, or the total winding length increases substantially, the slack caused by the lag in the winding speed will accumulate significantly. At this time, the push roller 15 is limited by its own range of movement, and its adjustment capability is difficult to cover the continuously increasing slack demand. In order to ensure that the push roller 15 can always cover the slack demand of the film, the present invention has made further improvements to the above-mentioned embodiment. In the initial working state, the electromagnet 22 is not energized, and the elastic force of the second spring 24 continuously acts on the sliding plate 23. The sliding plate 23 drives the push plate 25, the first elastic block 26 and the surface of the rotating shaft 5 to fit tightly. The first elastic block 26 is made of an elastic material with a high coefficient of friction. When it contacts the rotating shaft 5, a transmission connection is formed through the friction between the two. When the rotating shaft 5 rotates, the winding roller 6 can be driven to rotate synchronously through this friction, realizing the connection function of power transmission.

[0036] When the push rod 16 reaches its maximum range or touches the preset push stroke, the control system senses this state and triggers an adjustment action: At this time, the electromagnets 22 corresponding to the two electrode take-up rollers 6 are activated. The attraction force generated by the electromagnets 22 pulls the sliding plate 23 and the push plate 25 closer to it, thereby compressing the second spring 24. As the second spring 24 contracts, the push plate 25 drives the first elastic block 26 to gradually detach from the surface of the rotating shaft 5, so that the friction transmission connection between the rotating shaft 5 and the take-up roller 6 is disconnected. The rotating shaft 5 remains in an idling state, while the electrode take-up roller 6 stops rotating. During this process, the film take-up roller 6 is unaffected and continues to rotate, thus having sufficient time to wind up the accumulated slack. At the same time, the push rod 16 retracts synchronously to the initial position, reserving sufficient movement space for possible subsequent adjustment actions, ultimately achieving effective processing of the film slack and ensuring the stability of the winding process.

[0037] As a further embodiment of the present invention, a second elastic block 27 is fixed to one end of the push plate 25, and an inclined groove 28 is provided on the inner wall of the mounting groove 21. A guide rod 29 is inserted into the inclined groove 28 and the guide rod 29 is fixed on the push plate 25.

[0038] Specifically, as the push plate 25 moves upward in a preset direction under the action of driving force, the guide rod 29 installed on the side of the push plate 25 is embedded in the preset inclined groove 28 of the mounting base 8, and slides smoothly along the inclined trajectory of the inclined groove 28 as the push plate 25 rises. The inclination angle of the inclined groove 28 and the sliding trajectory of the guide rod 29 cooperate to form a compound guiding effect. While the push plate 25 moves upward, it is continuously subjected to lateral force by the side wall of the inclined groove 28, thereby driving the push plate 25 to slowly translate towards the side where the mounting base 8 is located. The side wall of the push plate 25 is fixed with a second elastic block 27, which gradually approaches the mounting base 8 as the push plate 25 translates, and finally makes the surface of the second elastic block 27 tightly fit with the side wall of the mounting base 8. During the fitting process, the second elastic block 27 ensures tight contact. The second elastic block 27 is made of a material with high friction. The elastic material with a coefficient of friction is roughened to enhance its friction performance. When it comes into contact with the rigid surface of the mounting base 8, the elastic deformation increases the contact area between the two. The resulting static friction force is sufficient to counteract the possible reverse movement tendency of the push plate 25 and the take-up roller 6, forming a stable mechanical positioning. This positioning effect is directly transmitted to the take-up roller 6, preventing it from rotating unexpectedly under external tension or inertia. This ensures that the take-up roller 6 remains stable when it needs to be stationary, avoiding material relaxation or tension fluctuations caused by unexpected rotation, and ultimately ensuring precise control of the winding process.

[0039] As a further embodiment of the present invention, the push plate 25 has a slot 30 inside, the bottom of the first elastic block 26 has a clearance hole 31 communicating with the slot 30, the slot 30 has an insert block 32 inserted inside, a third spring 33 is fixed between the insert block 32 and the inner wall of the slot 30, and an elastic member is fixed at the bottom of the insert block 32.

[0040] Specifically, this invention incorporates a third spring 33. Under the elastic force of the third spring 33, the elastic element is positioned protruding from the first elastic block 26. During movement, the elastic element first contacts the rotating shaft 5. Since the rotating shaft 5 is rotating, when the elastic element contacts the rotating shaft 5 first, it can rotate synchronously with the rotating shaft 5 under the action of friction. Thus, when the first elastic block 26 contacts the rotating shaft 5, it can maintain a relatively stationary state with the rotating shaft 5 in advance. This relatively stationary contact method transforms the sliding friction that might have occurred into static friction, significantly reducing the frictional loss at the moment of contact between the first elastic block 26 and the rotating shaft 5, effectively extending the service life of the component, and ensuring the smoothness of the transmission process.

[0041] As a further embodiment of the present invention, the elastic element includes a roller frame 34, which is fixed to the bottom of the insert block 32. A roller 35 is rotatably connected to the roller frame 34, and the roller 35 is made of an elastic material.

[0042] Specifically, the main body of the elastic element is a freely rotating wheel. The center of the wheel is connected to the roller frame 34 through a bushing. The wheel is made of a material that combines elasticity and wear resistance to ensure a tight fit with the surface of the rotating shaft 5. Since the elastic element needs to slide horizontally on the rotating shaft 5 after contacting it, under the action of the inclined groove 28, this invention, by setting the elastic element in the shape of a roller 35, can replace the sliding friction that might otherwise occur with rolling friction during horizontal sliding. The coefficient of friction for rolling friction is much smaller than that for sliding friction, which can significantly reduce the frictional resistance during horizontal sliding. This design not only reduces unnecessary wear between the elastic element and the surface of the rotating shaft 5, but also ensures that the elastic element maintains stable contact with the shaft during horizontal sliding, avoiding sliding jamming caused by excessive frictional resistance and ensuring the smoothness of the compound motion.

[0043] As a further embodiment of the present invention, a positioning groove 36 is provided on the side wall of the insert block 32, a vertical groove 37 is provided on the top surface of the push plate 25, a pull rod 38 is inserted in the vertical groove 37, a fifth spring 39 is fixed between the pull rod 38 and the inner wall of the vertical groove 37, a clearance groove 40 is provided on the top surface of the sliding plate 23, the top of the pull rod 38 passes through the clearance groove 40, and a docking assembly is provided on the side wall of the pull rod 38 for fixing the pull rod 38 and the insert block 32 together.

[0044] The docking assembly includes a first docking groove 41, which is formed on the side wall of the pull rod 38. A positioning pin 42 is inserted into the first docking groove 41. The bottom of the positioning pin 42 has an inclined surface. A fourth spring 43 is fixed between the positioning pin 42 and the docking groove. A second docking groove 44 is formed on the inner wall of the vertical groove 37. The second docking groove 44 is connected to the first docking groove 41 and the positioning groove 36 respectively.

[0045] Specifically, when the first elastic block 26 is in close contact with the rotating shaft 5, the electromagnet 22 is de-energized. Under the pushing action of the fifth spring 39, the first docking groove 41 on the pull rod 38 is connected to the second docking groove 44, while the roller 35 is in a retracted state under the blocking action of the rotating shaft 5. At this time, the second docking groove 44 is connected to the positioning groove 36, so that under the elastic force of the fourth spring 43, the positioning pin 42 can be pushed into the positioning groove 36 to position the insert block 32. When the first elastic block 26 is separated from the rotating shaft 5, since the insert block 32 is in a positioning state, the situation where the roller 35 is in long-term contact with the rotating shaft 5 under the pushing action of the third spring 33 during the separation process can be avoided, ensuring the timeliness of separation. As the push plate 25 rises, the pull rod 38 gradually contacts the surface of the electromagnet 22. Under the blocking action of the electromagnet 22, the pull rod 38 is pushed to compress the fifth spring 39, thereby causing the pull rod 38 to move downward relative to the push plate 25 and the insert block 32, and driving the positioning pin 42 to move downward. Guided by the inclined surface, the positioning pin 42 retracts into the interior of the first docking groove 41, and as it descends, it is gradually blocked by the side wall of the vertical groove 37, thereby canceling the positioning of the insert block 32. Under the elastic force of the third spring 33, the insert block 32 protrudes out of the outer side of the first elastic block 26 again, which is convenient for the next docking with the rotating shaft 5.

[0046] As a further embodiment of the present invention, a sliding groove 46 is provided on the connecting frame 20, a sliding block 45 is slidably connected in the sliding groove 46, a sixth spring 47 is fixed between the sliding block 45 and the sliding groove 46, and a pressure roller 48 is rotatably connected to the surface of the sliding block 45.

[0047] Specifically, by setting the sixth spring 47 to push the sliding block 45, the pressure roller 48 squeezes the wound electrode sheet in real time, thereby preventing the electrode sheet or film from loosening during the winding process and helping to ensure the winding effect.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
