Technical Field
[0001] This utility model relates to the field of waste battery dismantling technology, specifically to a battery core dismantling machine and a battery core dismantling production line. Background Technology
[0002] In order to maximize the resource recovery rate and the purity of the final product and realize the high-value recycling of materials, waste lithium batteries are usually disassembled in a refined manner when recycling them.
[0003] Valuable metals (such as lithium, cobalt, nickel, manganese, etc.) and key materials (such as graphite, copper, aluminum) in waste lithium batteries are mainly concentrated in the battery core. The battery core is usually a wound core - the core is usually made of a positive electrode sheet (usually an aluminum foil coated with lithium metal oxide), a negative electrode sheet (usually a copper foil coated with graphite), and a separator (mostly a porous polymer film) sandwiched between the two.
[0004] Currently, the precise disassembly of the core relies heavily on manual operation. It requires manual unwinding of the tightly wound core and manual separation into single-layer positive electrode plates, negative electrode plates, and separators. This disassembly method is very cumbersome and inefficient. Utility Model Content
[0005] The purpose of this utility model is to overcome the shortcomings of the prior art. This utility model provides a core disassembly machine and a core disassembly production line, which can effectively improve the disassembly efficiency of cores by replacing manual disassembly with mechanical means.
[0006] This utility model provides a core dismantling machine, including a base with an internal negative electrode recycling channel and an external positive electrode recycling channel, and a core support shaft, a first diaphragm traction roller group, a second diaphragm traction roller group, a diaphragm take-up shaft and a drive motor disposed on the base.

The first guide roller and the second guide roller maintain a first distance from the edge of the feed inlet of the negative electrode recycling channel. The first tension roller is mounted on the machine base based on a first tension seat. The first tension roller is rotatably mounted on the first tension seat. The first tension seat is movably mounted on the machine base based on a second linear drive mechanism.

The second tension roller is mounted on the machine base based on a second tension seat. The second tension roller is rotatably mounted on the second tension seat. The second tension seat is movably mounted on the machine base based on a third linear drive mechanism. The second tension seat is driven by the third linear drive mechanism to move away from or towards the feed inlet of the negative electrode recycling channel.
[0012] Specifically, in the non-working state of the core unwinding machine, the edges of the first guide roller, the first tension roller, and the second guide roller are all tangent to the same straight line, and the edges of the third guide roller, the second tension roller, and the fourth guide roller are all tangent to the same straight line.
[0013] When the core dismantling machine is in operation, a partial edge of the first tension roller intrudes into the feed inlet of the negative electrode recycling channel, and a partial edge of the second tension roller intrudes into the feed inlet of the negative electrode recycling channel.
[0014] Specifically, the negative electrode recycling channel is inclined from top to bottom, and the positive electrode recycling channel is inclined from top to bottom.
[0015] Specifically, the discharge port of the negative electrode recycling channel and the discharge port of the positive electrode recycling channel are both located on the same side of the machine base.

[0033] This utility model provides a core disassembly machine. Figure 1 This diagram illustrates a three-dimensional structure of a core-removing machine according to an embodiment of the present invention. The core-removing machine includes a base 1 with an internal negative electrode recovery channel 110 and an external positive electrode recovery channel 120, and a core support shaft 210, a first diaphragm traction roller group 310, a second diaphragm traction roller group 320, a diaphragm take-up shaft 410, and a drive motor 510 mounted on the base 1.

The first diaphragm 11 is wound around the first diaphragm traction roller group 310, and the end of the first diaphragm 11 is fixed to the diaphragm take-up shaft 410.

[0035] This invention uses a core disassembly machine to perform mechanized disassembly of the core, replacing manual disassembly. This makes the entire core disassembly process efficient and fast, significantly improving the disassembly efficiency of the core.
[0036] Moreover, the core dismantling machine of this invention is simple, easy to understand and use, and has low requirements for operators; in addition, the core dismantling machine has a low cost and the overall operating cost is also low.
[0037] Furthermore, the core dismantling machine of this utility model can dismantle a single core weighing between 0.5 and 2 kg. As long as the wound battery core is within this weight range, the core dismantling machine of this utility model can easily dismantle and process it, making it highly practical.
[0038] Figure 5 This diagram illustrates the structure of the core support shaft and core support base in an embodiment of the present invention. The core support shaft 210 is mounted on the machine base 1 based on the core support base 220. The core support shaft 210 is rotatably mounted on the core support base 220. The core support base 220 is movably mounted on the machine base 1 based on a first linear drive mechanism. The core support base 220 is driven by the first linear drive mechanism to move away from or towards the feed inlet of the negative electrode recycling channel 110. The position of the core support shaft 210 can be adjusted by the first linear drive mechanism. Please refer to [link to relevant documentation]. Figure 3 or Figure 4 This allows for adjustment of the separation angle between the first diaphragm 11 and the second diaphragm 12, which is beneficial for promoting the separation of the negative electrode 20 from the first diaphragm 11 and for promoting the separation of the positive electrode 30 from the second diaphragm 12.
[0039] The first linear drive mechanism is existing and is hidden inside the base 1; for example, the first linear drive mechanism can be a lead screw motor consisting of an electric motor, a lead screw and a movable nut.
[0040] In some specific embodiments, please refer to Figure 3 and Figure 4 The first diaphragm traction roller group 310 includes a first guide roller 311, a first guide roller 312, a first tension roller 313 and a second guide roller 314 arranged sequentially along the traction path of the first diaphragm 11. A partial edge of the first guide roller 311 penetrates into the feed inlet of the negative electrode recycling channel 110. The first guide roller 312 and the second guide roller 314 maintain a first distance from the edge of the feed inlet of the negative electrode recycling channel 110. Figure 6 The diagram shows the structure of the first tension roller and the first tension seat in an embodiment of the present invention. The first tension roller 313 is mounted on the machine base 1 based on the first tension seat 3131. The first tension roller 313 is rotatably disposed on the first tension seat 3131. The first tension seat 3131 is movably disposed on the machine base 1 based on the second linear drive mechanism. The first tension seat 3131 is driven by the second linear drive mechanism to move away from or towards the feed port of the negative electrode recycling channel 110.
[0041] The first guide roller 311 not only guides the traction direction of the first diaphragm 11, but also facilitates the separation of the negative electrode 20 from the first diaphragm 11 at this point. The first guide roller 312 and the second guide roller 314 support and guide the first diaphragm 11 to extend toward the diaphragm take-up shaft 410, and cooperate with the first tension roller 313 to adjust the tension of the first diaphragm 11. The position of the first tension roller 313 can be adjusted by the second linear drive mechanism, thereby adjusting the tightness of the first diaphragm 11 winding around the first diaphragm traction roller group 310. This facilitates the smooth winding of the first diaphragm 11 by the diaphragm take-up shaft 410 and also facilitates the separation of the negative electrode 20 from the first diaphragm 11.
[0042] The second linear drive mechanism is existing and is hidden inside the base 1; for example, the second linear drive mechanism can be a lead screw motor consisting of a motor, a lead screw and a movable nut.
[0043] Moreover, please see Figure 3 and Figure 4 The second diaphragm traction roller group 320 includes a second guide roller 321, a third guide roller 322, a second tension roller 323 and a fourth guide roller 324 arranged sequentially along the traction path of the second diaphragm 12. A partial edge of the second guide roller 321 penetrates into the feed inlet of the negative electrode recycling channel 110. The third guide roller 322 and the fourth guide roller 324 maintain the first distance from the edge of the feed inlet of the negative electrode recycling channel 110. Figure 7 The diagram shows the structure of the second tension roller and the second tension seat in an embodiment of the present invention. The second tension roller 323 is mounted on the machine base 1 based on the second tension seat 3231. The second tension roller 323 is rotatably disposed on the second tension seat 3231. The second tension seat 3231 is movably disposed on the machine base 1 based on the third linear drive mechanism. The second tension seat 3231 is driven by the third linear drive mechanism to move away from or towards the feed port of the negative electrode recycling channel 110.
[0044] The second guide roller 321, the third guide roller 322, and the fourth guide roller 324 are mainly used to support and guide the second diaphragm 12 to extend toward the diaphragm take-up shaft 410. The third guide roller 322 and the fourth guide roller 324 are also used to cooperate with the second tension roller 323 to adjust the tension of the second diaphragm 12. The position of the second tension roller 323 can be adjusted by the third linear drive mechanism, thereby adjusting the tightness of the second diaphragm 12 winding in the second diaphragm traction roller group 320. On the one hand, this is conducive to promoting the smooth winding of the second diaphragm 12 by the diaphragm take-up shaft 410, and on the other hand, it is conducive to promoting the separation of the positive electrode sheet 30 from the second diaphragm 12.
[0045] The third linear drive mechanism is existing and is hidden inside the base 1; for example, the third linear drive mechanism can be a lead screw motor consisting of a motor, a lead screw and a movable nut.
[0046] When the core unwinding machine is not in operation, please refer to Figure 3 The edges of the first guide roller 312, the first tension roller 313, and the second guide roller 314 are all tangent to the same straight line. Similarly, the edges of the third guide roller 322, the second tension roller 323, and the fourth guide roller 324 are all tangent to the same straight line. This design facilitates, on the one hand, the operator's movement through the first diaphragm 11 in the first diaphragm traction roller group 310 and through the second diaphragm 12 in the second diaphragm traction roller group 320. On the other hand, it provides sufficient space for the first tension roller 313 and the second tension roller 323 to adjust the tension of the first diaphragm 11 and the second tension roller 323.
[0047] Please refer to the following for the operating status of the core unwinding machine. Figure 4 The first tension roller 313 partially penetrates the feed inlet of the negative electrode recycling channel 110, and the second tension roller 323 partially penetrates the feed inlet of the negative electrode recycling channel 110. At this time, the first tension roller 313 pushes the first diaphragm 11 into the feed inlet of the negative electrode recycling channel 110, making the first diaphragm 11 taut. This facilitates the smooth winding of the first diaphragm 11 by the diaphragm take-up shaft 410 and also facilitates the separation of the negative electrode 20 from the first diaphragm 11. The second tension roller 323 pushes the second diaphragm 12 into the feed inlet of the negative electrode recycling channel 110, making the second diaphragm 12 taut. This facilitates the smooth winding of the second diaphragm 12 by the diaphragm take-up shaft 410 and also facilitates the separation of the positive electrode 30 from the second diaphragm 12.
[0048] In some specific embodiments, please refer to Figure 1 The negative electrode recycling channel 110 is inclined from top to bottom to facilitate the automatic sliding of the negative electrode 20; the positive electrode recycling channel 120 is inclined from top to bottom to facilitate the automatic sliding of the positive electrode 30.
[0049] For details, please refer to Figure 1The discharge ports of the negative electrode recycling channel 110 and the positive electrode recycling channel 120 are both located on the same side of the base 1. On one hand, this allows operators to collect materials, change containers, or monitor the discharge from only one side of the base 1, eliminating the need to walk around the core unwinding machine or switch between different sides, significantly reducing operator movement distance and operation time. On the other hand, if automated conveyors, AGVs, or collection systems are subsequently added, the interface design only needs to be done on the same side, simplifying the difficulty and cost of automation integration.
[0050] For further details, please refer to Figure 1 The discharge ports of the negative electrode recycling channel 110 and the positive electrode recycling channel 120 are vertically spaced, with the discharge port of the negative electrode recycling channel 110 being lower than that of the positive electrode recycling channel 120. This height difference allows operators to stagger the placement of collection containers or conveyor belts, improving space utilization.
[0051] In some specific embodiments, a first vibration motor is provided on the back side of the negative electrode recycling channel 110, which can provide high-frequency low-amplitude vibration to promote the rapid sliding of the negative electrode 20 material and prevent the negative electrode 20 material from being retained in the negative electrode recycling channel 110; a second vibration motor is provided on the back side of the positive electrode recycling channel 120, which can provide high-frequency low-amplitude vibration to promote the rapid sliding of the positive electrode 30 material and prevent the positive electrode 30 material from being retained in the positive electrode recycling channel 120.
[0052] The method of using the core unwinding machine of this utility model is as follows:
[0053] First, insert the center of the core onto the core support shaft 210; then, pull out a section of the first diaphragm 11, the negative electrode 20, the second diaphragm 12, and the positive electrode 30 from the core. Thread the first diaphragm 11 around the first diaphragm traction roller group 310 and fix the end of the first diaphragm 11 onto the diaphragm take-up shaft 410. Feed the negative electrode 20 into the feed inlet of the negative electrode recovery channel 110. Thread the second diaphragm 12 around the second diaphragm traction roller group 320 and fix the end of the second diaphragm 12 onto the diaphragm take-up shaft 410. Feed the positive electrode 30 into the feed inlet of the positive electrode recovery channel 120. Next, start the first linear drive mechanism to adjust... The position of the core support shaft 210 is adjusted by starting the second linear drive mechanism to adjust the position of the first tension roller 313, and the position of the third linear drive mechanism to adjust the position of the second tension roller 323. The first tension roller 313 pushes the first diaphragm 11 into the feed inlet of the negative electrode recycling channel 110, and the second tension roller 323 pushes the second diaphragm 12 into the feed inlet of the negative electrode recycling channel 110. Then, the drive motor 510 is started to drive the diaphragm take-up shaft 410 to rotate and wind up the first diaphragm 11 and the second diaphragm 12. The negative electrode 20 automatically falls into the negative electrode recycling channel 110, and the positive electrode 30 automatically falls into the positive electrode recycling channel 120.
[0054] This invention utilizes a core-disassembly machine to mechanically disassemble battery cores, replacing manual disassembly and making the entire process highly efficient and rapid, significantly improving disassembly efficiency. Furthermore, the core-disassembly machine is simple to understand and operate, requiring minimal operator skill; its cost is also low, resulting in lower overall operating costs. In addition, this core-disassembly machine can disassemble cores weighing between 0.5 and 2 kg. As long as the battery cores fall within this weight range, this machine can easily disassemble and process them, demonstrating its practicality.
[0055] This utility model also provides a core disassembly assembly line. Figure 8 A schematic diagram of the core dismantling production line in an embodiment of this utility model is shown. The core dismantling production line consists of multiple core dismantling machines. The discharge ports of the negative electrode recovery channels 110 of the multiple core dismantling machines are connected via a first conveyor belt 41, and the discharge ports of the positive electrode recovery channels 120 of the multiple core dismantling machines are connected via a second conveyor belt 42. The production line composed of multiple core dismantling machines can process cores of different battery cells simultaneously, eliminating the bottleneck of single-machine capacity and facilitating a significant increase in dismantling efficiency.
[0056] The battery core dismantling production line of this invention can realize batch and efficient dismantling of battery cores, which greatly improves the dismantling efficiency of battery cores, thereby improving resource recycling efficiency and reducing resource recycling costs, and thus promoting the standardization and large-scale development of the battery recycling industry.
[0057] In some specific embodiments, the core dismantling machine is equipped with 10 units, which can process at least 1,000 cores per hour (the weight of a single core ranges from 0.5 to 2 kg), meeting the industrial-grade throughput requirements for lithium battery recycling.
[0058] The above provides a detailed description of a core dismantling machine and core dismantling production line provided by the embodiments of this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
