Description

Technical Field

[0001] This invention relates to the technical field of dismantling devices for waste battery packs, specifically a CTP battery pack dismantling device and its dismantling method. Background Technology

[0002] In the recycling of used battery packs, it is usually necessary to disassemble the battery packs beforehand. However, since the battery packs are typically glued together, they need to be heat-treated or cold-treated before disassembly to deactivate the glue and ensure that the battery packs can be easily disassembled manually. This method is time-consuming and labor-intensive, making it difficult to guarantee the efficiency of battery pack disassembly. Furthermore, during the heat treatment process, the battery packs may even be at risk of spontaneous combustion. In addition, the heat-treated or cold-treated battery packs also make manual disassembly more difficult. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a CTP battery pack disassembly device and a disassembly method thereof.

[0004] The technical solution of this invention is as follows: The present invention first provides a CTP battery pack disassembly device, including a main frame and a disassembly system thereon. A transfer system is also provided on one side of the main frame. The transfer system can transport the battery pack to be disassembled to the main frame, and the disassembly system can complete the disassembly of the battery pack on the main frame.

[0005] As the core technical concept of this invention, the main frame includes a frame body, and the transfer system includes a second guide rail with one end located inside the lower side of the frame body and the other end extending outside the frame body. The layout direction of the second guide rail is consistent with the length direction of the first channel steel bar, and a lifting transfer vehicle capable of supporting the battery pack is slidably mounted on it. Two first channel steel bars with opposite openings and U-shaped cross sections are also arranged parallel to each other on the upper two sides of the frame body. The openings of the two first channel steel bars are configured to accommodate the outer edges of the upper two sides of the battery pack. The unpacking system includes a first guide rail with one end located inside the middle of the frame body and the other end extending outside the frame body. A slider is slidably mounted on the first guide rail, and a top block is provided on the upper side of the slider through a second telescopic cylinder. A first telescopic cylinder is provided between the slider and the outer end of the first guide rail.

[0006] Based on the above structure, the lifting and transfer vehicle can be raised and lowered until the outer edges of both sides of the battery pack are at the same height as the first channel steel bars. By moving, the battery pack can be slidably inserted between the two first channel steel bars from the feeding end of the two first channel steel bars, and then retracted. The battery pack can be fixed between the two first channel steel bars by the cooperation and locking of the outer edges of both sides with the two first channel steel bars. By the action of the first telescopic cylinder, the slider can be sent to the bottom of the battery pack. By the action of the second telescopic cylinder, the top block can be moved upward, pushing from the lower middle side of the battery pack. Since the outer edges of the battery pack are fixed relative to the first channel steel bars, the upward movement of the top block can cause deformation at the bottom of the battery pack, thereby pushing the battery pack inside the battery pack away from the battery pack, completing the rigid dismantling of the battery pack inside the battery pack. There is no need for cold or heat treatment, which improves the dismantling efficiency of the battery pack and effectively saves labor costs.

[0007] As described above, in a preferred embodiment of the CTP battery pack disassembly device, the upper end face of the top block is an arc end face. Based on this structure, the bottom of the battery pack will undergo arc deformation under the action of the top block, ensuring that the upward movement of the top block can smoothly push the battery pack inside the battery pack apart, effectively ensuring the disassembly effect of the battery pack.

[0008] As a further preferred embodiment, in order to reduce the damage to the first channel steel bar caused by the battery pack when the top block moves upward, and at the same time to ensure that the bottom of the battery pack can deform smoothly under the clamping force, the axis of the arc end face is perpendicular to the length direction of the first channel steel bar.

[0009] Preferably, to further ensure that the upward movement of the top block can smoothly disperse the battery pack inside the battery pack, the center of the arc end face is provided with an arc-shaped protrusion that fits and is coaxial with it. On this basis, under the action of the top block, the multiple rows of battery packs along the length direction of the first channel steel bar inside the battery pack can be effectively dispersed. At the same time, under the action of the protrusion, the multiple rows of battery packs perpendicular to the length direction of the first channel steel bar inside the battery pack can also be effectively dispersed, effectively ensuring the disassembly effect of the unpacking system.

[0010] As described above, in order to improve the lifting and transporting effect of the lifting and transporting system, the lifting and transporting vehicle adopts a scissor lifting method.

[0011] In a preferred embodiment, to ensure the stability of the slider sliding relative to the first guide rail, the first guide rail includes two second channel steel bars with opposite openings and U-shaped cross sections, and the two sides of the slider are respectively slidably disposed within the two second channel steel bars.

[0012] As a further preferred embodiment, in order to further ensure the stability of the slider sliding between the two second channel steel bars, prevent the slider from being damaged by sliding, ensure the rigid fit between the slider and the two second channel steel bars, and at the same time ensure the action of the second telescopic cylinder, so as to smoothly drive the top block to lift the bottom of the battery pack, two third channel steel bars are fastened on both sides of the slider, and the third channel steel bars slide in fit with the second channel steel bars.

[0013] The CTP battery pack disassembly device described above further includes a detection system. This detection system includes a first detector positioned above the feeding end of at least one first channel steel bar, capable of detecting the feeding status of the battery pack. The first detector detects the length of the battery pack along the length direction of the first channel steel bar, allowing the battery pack to be smoothly placed in the middle between two first channel steel bars. To prevent spontaneous combustion when the battery pack is rigidly disassembled or subjected to rigid disassembly, the detection system also includes multiple sets of second detectors positioned above the two first channel steel bars and equidistantly arranged along the first guide rail, capable of detecting the disassembly temperature of the battery pack. These second detectors can monitor the disassembly temperature of the battery pack in real time, preventing spontaneous combustion due to rigid force and ensuring the safety of battery pack disassembly.

[0014] Furthermore, the dismantling device also includes a controller that is communicatively connected to the first detector, the second detector, the second telescopic cylinder, the first telescopic cylinder, and the lifting transfer vehicle. The controller is configured to control the operation of the first detector, the second detector, the second telescopic cylinder, the first telescopic cylinder, and the lifting transfer vehicle.

[0015] The present invention also provides a method for disassembling a CTP battery pack. Based on the above-mentioned disassembly device, the disassembly method specifically includes the following steps: S1, Packing; The lifting and transfer vehicle moves and, based on the feedback value from the first detector, delivers the battery pack to the middle position between the two first channel steel bars, and then retracts. S2, Unpacking; The first telescopic cylinder pushes the slider to the area below the middle of the two first channel steel bars. The second telescopic cylinder, based on the feedback value of the second detector, moves the top block upward to complete the disassembly of the battery pack inside the battery pack, and then retracts. S3, Return Package; The lifting and transfer vehicle moves to carry the battery pack out from between the two first channel steel bars.

[0016] As described above, in order to further ensure the safety of battery pack disassembly and prevent the disassembly process from being suspended when the battery pack temperature inside the battery pack is too high, thus ensuring the disassembly efficiency, in step S2, each group of the second detectors corresponds to a detection area, and each detection area corresponds to a unique preset temperature threshold t. Step S2 is specifically as follows: S2.1, The first telescopic cylinder moves to push the slider to the area below the middle of the two first channel steel bars, and the top block corresponds vertically to the middle second detector; The second detector corresponding to the top block is a parameter detector, and the preset temperature threshold of the detection area corresponding to the parameter detector is t1; The second detectors on both sides of the parameter detector are control detectors; S2.2 The second telescopic cylinder moves the top block upward, and the parameter detector detects the temperature N of the corresponding detection zone in real time; If N < t1, then push the top block to continue moving upward; if N ≥ t1, then execute step S2.3. S2.3. The two control detectors detect the temperature of their corresponding detection areas respectively, and select the control detector with the lower temperature of the corresponding detection area as the new parameter detector. At the same time, the preset temperature threshold of the detection area corresponding to it is used as the new t1, and the second detector on both sides of it is used as the new control detector. S2.4 The first telescopic cylinder moves the slider until the top block aligns with the new parameter detector. S2.5 Execute steps S2.2-S2.4 until step S2.2 removes all battery packs from the battery pack, and then the first telescopic cylinder moves to drive the slider back.

[0017] Based on the above method, when the temperature of the battery pack at the corresponding top block position is too high, the top block can be repositioned according to the different detection zones, and the battery pack inside the battery pack can be disassembled at different positions, ensuring both the safety and efficiency of disassembly.

[0018] The beneficial effects of this invention are as follows: This invention is a CTP battery pack disassembly device and its disassembly method. The lifting and transferring vehicle of the disassembly device can be raised to the same height as the outer edges of the battery pack on both sides and the first channel steel bars. By moving, the battery pack can be slidably inserted between the two first channel steel bars from the feeding end of the two first channel steel bars, and then retracted. The battery pack can be fixed between the two first channel steel bars by the cooperation and locking of the outer edges of both sides with the two first channel steel bars. By the action of the first telescopic cylinder, the slider can be sent to the bottom of the battery pack. By the action of the second telescopic cylinder, the top block can be moved upward and pushed from the lower middle side of the battery pack. Since the outer edges of the battery pack are fixed relative to the first channel steel bars, the upward movement of the top block can cause deformation at the bottom of the battery pack, thereby pushing the battery pack inside the battery pack away from the battery pack, completing the rigid disassembly of the battery pack inside the battery pack. There is no need for cold treatment or heat treatment, which improves the disassembly efficiency of the battery pack and effectively saves labor costs. Attached Figure Description

Detailed Implementation

[0021] Exemplary embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings.

[0022] Example This embodiment first provides a CTP battery pack 5 disassembly device, see [link]. Figure 1 The device includes a main frame 1 and a disassembly system 2 mounted thereon. A transfer system 3 is also provided on one side of the main frame 1. The transfer system 3 is configured to transport the battery pack 5 to be disassembled to the main frame 1, and the disassembly of the battery pack 5 on the main frame 1 can be completed through the disassembly system 2. The structure of the disassembly device (the above-mentioned CTP battery pack 5 disassembly device) will be described in detail below with reference to the accompanying drawings.

[0023] In this embodiment, as one of the core technical concepts of the present invention, combined with Figure 2 The main frame 1 includes a frame body 11. Two first channel steel bars 12 with U-shaped cross-sections and opposite openings are provided on the upper two sides of the frame body 11. The openings of the two first channel steel bars 12 are configured to accommodate the outer edges of the upper two sides of the battery pack 5. The transfer system 3 includes a second guide rail 31 with one end located inside the lower side of the frame body 11 and the other end extending outside the frame body 11. The layout direction of the second guide rail 31 is consistent with the length direction of the first channel steel bars 12, and a lifting transfer vehicle 32 capable of supporting the battery pack 5 is slidably mounted on it.

[0024] Based on the above structure, the lifting and transfer vehicle 32 can be raised and lowered to the same height as the outer edges of the battery pack 5 and the first channel steel bar 12. By moving, the battery pack 5 can be slidably inserted between the two first channel steel bars 12 from the feeding end of the two first channel steel bars 12, and then retracted. The battery pack 5 can be fixed between the two first channel steel bars 12 by the cooperation and locking of the outer edges of the two sides with the two first channel steel bars 12. Then, the disassembly of the battery pack 5 between the two first channel steel bars 12 is completed by the unpacking system 2.

[0025] As a preferred embodiment of this invention, in order to improve the lifting and transporting effect of the lifting and transporting system 3, the lifting and transporting vehicle 32 adopts a scissor lift method.

[0026] As a further preferred embodiment, in order to ensure the stability of the relative positional relationship between the two first channel steel bars 12, and at the same time to ensure that the battery pack 5 is over-transported between the two first channel steel bars, a stop bar 13 is connected between the ends of the two first channel steel bars 12 that are away from the feed end.

[0027] In this embodiment, combined with Figure 3As another core technical concept of the present invention, the unpacking system 2 includes a first guide rail 21 with one end located in the middle of the interior of the frame body 11 and the other end extending out of the frame body 11. A slider 22 is slidably provided on the first guide rail 21, and a top block 26 is provided on the upper side of the slider 22 through a second telescopic cylinder 25. A first telescopic cylinder 24 is provided between the slider 22 and the outer end of the first guide rail 21.

[0028] Based on the above structure, the action of the first telescopic cylinder 24 can send the slider 22 to the bottom of the battery pack 5 between the two first channel steel bars 12. The action of the second telescopic cylinder 25 can drive the top block 26 to move upward and push it from the lower middle side of the battery pack 5. Since the outer edge of the battery pack 5 is fixed relative to the first channel steel bars 12, the upward movement of the top block 26 can cause deformation at the bottom of the battery pack 5, thereby pushing the battery pack inside the battery pack 5 away from the battery pack 5, completing the rigid disassembly of the battery pack inside the battery pack 5. There is no need for cold treatment or heat treatment, which improves the disassembly efficiency of the battery pack 5 and effectively saves labor costs.

[0029] As a preferred embodiment of this invention, the upper end face of the top block 26 is an arc end face. Based on this structure, the bottom of the battery pack 5 will undergo arc-shaped deformation under the action of the top block 26, ensuring that the upward movement of the top block 26 can smoothly push the battery pack inside the battery pack 5 apart, effectively ensuring the disassembly effect of the battery pack 5.

[0030] As a further preferred embodiment, in order to reduce the damage to the first channel steel bar 12 caused by the battery pack 5 when the top block 26 moves upward, and at the same time to ensure that the bottom of the battery pack 5 can deform smoothly under the clamping force, the axis of the arc end face is perpendicular to the length direction of the first channel steel bar 12.

[0031] Preferably, to further ensure that the upward movement of the top block 26 can smoothly disperse the battery packs inside the battery pack 5, an arc-shaped protrusion 27 is provided in the middle of the arc end face and is coaxial with it. On this basis, under the action of the top block 26, the multiple rows of battery packs inside the battery pack 5 along the length direction of the first channel steel bar 12 can be effectively dispersed. At the same time, under the action of the protrusion 27, the multiple rows of battery packs inside the battery pack 5 perpendicular to the length direction of the first channel steel bar 12 can also be effectively dispersed, effectively ensuring the disassembly effect of the unpacking system 2.

[0032] In this embodiment, as a preferred implementation, to ensure the stability of the slider 22 sliding relative to the first guide rail 21, the first guide rail 21 includes two second channel steel bars 211 with opposite openings and U-shaped cross sections, and the two sides of the slider 22 are respectively slidably disposed in the two second channel steel bars 211.

[0033] Combination Figure 4As a further preferred embodiment, in order to further ensure the stability of the slider 22 sliding between the two second channel steel bars 211, prevent the slider 22 from being damaged by sliding, ensure the rigid fit between the slider 22 and the two second channel steel bars 211, and at the same time ensure that the action of the second telescopic cylinder 25 can smoothly drive the top block 26 to lift the bottom of the battery pack 5, two third channel steel bars 28 are fastened on both sides of the slider 22, and the third channel steel bars 28 slide in fit with the second channel steel bars 211.

[0034] In this embodiment, combined with Figure 5 The disassembly device also includes a detection system 4, which includes a first detector 41 located above the feeding end of at least one first channel steel bar 12 and capable of detecting the feeding status of the battery pack 5. The first detector 41 can detect the length of the battery pack 5 along the length direction of the first channel steel bar 12, thereby enabling the battery pack 5 to be smoothly placed in the middle between the two first channel steel bars 12.

[0035] Regarding the detection method of the first detector 41, when the transport speed of the lifting transfer vehicle 32 is constant, the length of the outer edge can be detected by the first detector 41 after the outer edge passes the first detector 41 and the time difference between the detection of the outer edge ...

[0036] Furthermore, the detection system 4 also includes multiple sets of mounting frames 42 arranged equidistantly above the two first channel steel bars 12 and along the first guide rail 21. Each of the mounting frames 42 is equipped with a second detector 43 capable of detecting the unpacking temperature of the battery pack 5. The second detector 43 can detect the unpacking temperature of the battery pack 5 in real time, preventing the battery pack from spontaneously combusting under rigid stress and ensuring the safety of unpacking the battery pack 5.

[0037] As a preferred embodiment, to further ensure the safety of disassembling the battery pack 5 and prevent spontaneous combustion when the battery pack is rigidly disassembled or subjected to rigid disassembly, i.e., to prevent the disassembly of the battery pack 5 from being suspended when the temperature of the battery pack inside the battery pack 5 is too high and reaches the ignition point, thus ensuring the disassembly efficiency of the battery pack 5, each group of the second detectors 43 corresponds to a detection area, and each detection area corresponds to a unique and preset temperature threshold t. The disassembly system 2 is configured to complete the disassembly of the battery pack inside the battery pack 5 by switching the detection values ​​of several groups of second detectors 43.

[0038] Furthermore, the disassembly device also includes a controller that is communicatively connected to the first detector 41, the second detector 43, the second telescopic cylinder 25, the first telescopic cylinder 24, and the lifting and transferring vehicle 32. The controller is configured to control the operation of the first detector 41, the second detector 43, the second telescopic cylinder 25, the first telescopic cylinder 24, and the lifting and transferring vehicle 32, ensuring that the disassembly of the battery pack 5 can be carried out automatically.

[0039] This embodiment also provides a method for disassembling a CTP battery pack 5. The disassembly method is based on the disassembly device described above, combined with... Figure 6 The disassembly method specifically includes the following steps: S1, Packing; The lifting and transfer vehicle 32 operates, and based on the feedback value from the first detector 41, it delivers the battery pack 5 to the middle position between the two first channel steel bars 12, and then returns. Specifically: S1.1 The battery pack 5 is manually placed on the lifting transfer vehicle 32; S1.2, The lifting and transfer vehicle 32 is adjusted until the outer edges of both sides of the battery pack 5 are at the same height as the first channel steel bar 12; S1.3 The lifting and transfer vehicle 32 moves to drive the battery pack 5 to be inserted between the feeding ends of the two first channel steel bars 12, and combined with the feedback value of the first detector 41, the battery pack 5 is sent to the middle position between the two first channel steel bars 12. S1.4 The lifting and transfer vehicle 32 descends, places the battery pack 5 between the two first channel steel bars 12, and then retracts; S2, Unpacking; The first telescopic cylinder 24 pushes the slider 22 to the area below the middle of the two first channel steel bars 12. The second telescopic cylinder 25, based on the feedback value from the second detector 43, moves the top block 26 upwards to complete the removal of the battery pack 5, and then retracts. Figure 7 Specifically: S2.1, the first telescopic cylinder 24 pushes the slider 22 to the area below the middle of the two first channel steel bars 12, and the top block 26 corresponds vertically to the middle second detector 43; At this time, the second detector 43 corresponding to the top block 26 is defined as a parameter detector, and the preset temperature threshold of the detection area corresponding to the parameter detector is t1; Simultaneously, the second detectors 43 on both sides of the parameter detector are defined as control detectors; S2.2, The second telescopic cylinder 25 moves the top block 26 upward, and the parameter detector detects the temperature N of the corresponding detection area in real time; If N < t1, then push the top block 26 to move up; if N ≥ t1, then continue to execute step S2.3. S2.3. The two control detectors detect the temperature of their corresponding detection areas respectively, and select a set of control detectors with lower temperature in the corresponding detection area. The control detector is defined as a new parameter detector, and the preset temperature threshold of the detection area corresponding to it is used as the new t1. At the same time, the second detectors 43 on both sides of it are defined as new control detectors. It should be noted that if the new parameter detector is the second detector 43 at the outermost edge, then return to step S2.1 and continue running; S2.4 The action of the first telescopic cylinder 24 drives the slider 22 to move until the top block 26 corresponds vertically with the new parameter detector; S2.5 Execute steps S2.2-S2.4 until step S2.2 removes all battery packs in battery pack 5. Then the second telescopic cylinder 25 controls the top block 26 to move down, and the first telescopic cylinder 24 moves to drive the slider 22 to retract. S3, Return Package; The lifting and transfer vehicle 32 moves to remove the battery pack 5 between the two first channel steel bars 12. Specifically: S3.1, The lifting and transfer vehicle 32 moves to below the battery pack 5; S3.2, The lifting and transfer vehicle 32 rises until it lifts the battery pack 5 between the two first channel steel bars 12; S3.3, The lifting and transfer vehicle 32 moves to drive the battery pack 5 out of the main frame 1.

[0040] Based on the above method, when the temperature of the battery pack at the corresponding position of the top block 26 is too high, the top block 26 can be repositioned according to the different detection zones, so as to remove the battery pack inside the battery pack 5 from different positions, thus ensuring the safety of disassembly while ensuring the efficiency of disassembly of the battery pack 5.
