Description

Technical Field

[0001] This utility model relates to the field of battery recycling technology, and in particular to a battery pack dismantling device. Background Technology

[0002] For electric vehicles, the power battery pack is a crucial component, typically consisting of a battery pack casing and numerous individual cells. Power battery packs can be categorized into two types based on the method of cell assembly: the first type combines several cells into a module, and then several modules are assembled into a battery pack – this is the traditional type. The second type directly assembles several cells into a battery pack (Cell to Pack, module-less power battery pack, or CTP). To ensure the cells are securely mounted to the bottom casing and prevent damage from bumps or other external forces, current CTP battery packs typically have a thick layer of two-component adhesive on the bottom casing. However, after several years of use, CTP battery packs no longer meet the technical performance requirements for automotive power batteries and must be scrapped within a specified timeframe (i.e., battery pack retirement). While the individual cells in the retired battery pack may not meet the performance requirements for electric vehicles, they can be reused in products such as streetlights and power banks, achieving secondary utilization.

[0003] When recycling retired battery packs, it is necessary to manually use a sledgehammer to knock the bottom of the CTP battery pack to detach the individual cells, which is time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this utility model is to provide a battery pack disassembly device to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0005] The technical solution adopted to solve the above-mentioned technical problems is as follows: a battery pack disassembly device, comprising: a first support, on which a first fixed pulley is installed; an impact cylinder, vertically mounted on the first support, wherein a movable pulley is installed at the output end of the impact cylinder, the height of the movable pulley being lower than the height of the first fixed pulley; a rope, one end of which is fixed to the first support, and the other end of which passes through the movable pulley and the first fixed pulley before being mounted with an impact hammer; when the output end of the impact cylinder is driven to rise, the impact hammer can be lowered; when the output end of the impact cylinder is driven to fall, the impact hammer can be raised.

[0006] This technical solution offers at least the following advantages: When the output end of the drive impact cylinder rises, the movable pulley rises, and the weight of the impact hammer straightens the rope, causing the impact hammer to move downwards, thus striking the battery pack. When the output end of the drive impact cylinder descends, the movable pulley descends, causing the impact hammer to be pulled up by the rope, enabling repeated striking of the battery pack. This allows the impact hammer to be driven by the drive impact cylinder, reducing the time and effort required for manual striking. Furthermore, the impact force is even, minimizing the risk of deformation of individual cells within the battery pack, ensuring that the cells meet the standards for reuse. The movable pulley also reduces the stroke of the impact cylinder by half, increasing its movement speed and improving striking efficiency.

[0007] As a further improvement to the above technical solution, the first support is also equipped with a second fixed pulley arranged side by side with the first fixed pulley. The end of the rope away from the first support passes sequentially around the movable pulley, the first fixed pulley, and the second fixed pulley before connecting to the impact hammer. The second fixed pulley can increase the lateral distance between the impact hammer and the movable pulley, reducing the impact of the impact hammer on the movable pulley during the striking process.

[0008] As a further improvement to the above technical solution, a second bracket is also included. The first bracket is slidably disposed on the second bracket, and a first driving member for driving the first bracket and the second bracket to slide relative to each other is installed between the first bracket and the second bracket. Driving the first driving member can move the first bracket relative to the second bracket, thereby driving the hammer to strike the battery pack at different linear positions.

[0009] As a further improvement to the above technical solution, the first driving component comprises a first motor, a transverse gear mounted on the output end of the first motor, and a rack meshing with the transverse gear. The first motor is mounted on one of the first bracket and the second bracket, and the rack is mounted on the other of the first bracket and the second bracket. Driving the first motor to rotate the transverse gear can, under the transmission action of the transverse gear and the rack, drive the first bracket to move relative to the second bracket.

[0010] As a further improvement to the above technical solution, a guide rail is also included. The second bracket is slidably mounted on the guide rail, and the direction in which the second bracket slides relative to the guide rail is perpendicular to the direction in which it slides relative to the first bracket. The second bracket is equipped with a second driving member for driving the second bracket to slide relative to the guide rail. Driving the second driving member causes the second bracket to slide on the guide rail, and the direction of sliding is perpendicular to the direction in which the first bracket slides relative to the second bracket. By controlling the first and second driving members, the first bracket can be moved relative to the guide rail within a planar range, thereby driving the hammer to strike the battery pack at different positions on the plane.

[0011] As a further improvement to the above technical solution, two guide rails are provided. A drive wheel and a follower wheel are respectively provided on both sides of the second bracket. The drive wheel and the follower wheel on the same side roll together on the same guide rail. The second driving component includes a transmission rod rotatably mounted on the second bracket and a second motor mounted on the second bracket. The second motor drives the transmission rod to rotate. First synchronous pulleys are mounted at both ends of the transmission rod, and second synchronous pulleys are coaxially mounted on the drive wheel. A synchronous belt is fitted onto the first and second synchronous pulleys on the same side. By driving the second motor, the transmission rod rotates. Under the transmission action of the first synchronous pulleys, the transmission belt, and the second synchronous pulleys, the two drive wheels rotate, thereby allowing the second bracket to move linearly relative to the guide rails.

[0012] As a further improvement to the above technical solution, a third bracket is also included. The third bracket is equipped with a clamping cylinder, and a pressure plate is installed at the output end of the clamping cylinder. The clamping cylinder is used to drive the pressure plate to clamp the battery pack onto the third bracket. The battery pack is placed on the third bracket, and then the clamping cylinder is driven to move the pressure plate, clamping the battery pack between the pressure plate and the third bracket. This restricts the position of the battery pack and reduces displacement during impacts.

[0013] As a further improvement to the above technical solution, a support frame is installed at the output end of the impact cylinder, and a rotating shaft is installed on the support frame. The movable pulley is rotatably mounted on the rotating shaft, and the rotating shaft or the support frame is slidably connected to the first bracket. The first bracket restricts the sliding direction of the support frame or the rotating shaft, which can improve the stability of the movable pulley's movement.

[0014] As a further improvement to the above technical solution, limit wheels are rotatably mounted at both ends of the rotating shaft, and two limit frames are mounted on the first bracket. The outer circumferences of the two limit wheels respectively abut against the side walls of the corresponding limit frames. By using limit frames to restrict the position of the limit wheels, the position of the rotating shaft is restricted. In restricting the sliding position of the rotating shaft, the impact on the rotation of the shaft itself can also be reduced, resistance can be reduced, and the movable pulley can rotate normally and smoothly.

[0015] As a further improvement to the above technical solution, the first bracket is equipped with a guide rod, and the impact hammer is slidably mounted on the guide rod. The guide rod can guide the falling direction of the impact hammer, improving the stability of the impact hammer during the lifting and lowering process and the striking process.

[0026] Reference Figure 1-4 The battery pack disassembly equipment includes a first support 100, an impact cylinder 200, and a rope 220. The first support 100 has a top plate 101 suspended in the middle. A first fixed pulley 110 and a second fixed pulley 120 are mounted on the bottom of the top plate 101, with the rotation center lines of the first fixed pulley 110 and the second fixed pulley 120 parallel to each other. The impact cylinder 200 is mounted on the top plate 101, with its output end facing vertically downwards. The impact cylinder 200 is positioned on the side of the first fixed pulley 110 furthest from the second fixed pulley 120. A support frame 600 is mounted on the output end of the impact cylinder 200, and a movable pulley 210 is mounted on the support frame 600.

[0027] The support frame 600 has a U-shaped cross-section with the opening facing downwards. A rotating shaft 610 is installed on both sides of the support frame 600. The movable pulley 210 is rotatably mounted in the middle of the rotating shaft 610 via bearings, meaning the movable pulley 210 is located in the middle spatial position of the support frame 600. The impact cylinder 200 is either a pneumatic cylinder or a hydraulic cylinder, preferably a pneumatic cylinder. The impact cylinder 200 can drive the movable pulley 210 to move up and down, i.e., lift and drop.

[0028] Both ends of the rotating shaft 610 extend beyond the support frame 600 by a certain length. Each end of the rotating shaft 610 extending beyond the support frame 600 is rotatably mounted with a limiting wheel 620 via bearings. Two limiting frames 630 are installed on the first bracket 100. The cross-section of the limiting frames 630 is also U-shaped, and the openings of the two limiting frames 630 are arranged oppositely. The two limiting wheels 620 are located within the two limiting frames 630, and they abut against the sidewalls of the corresponding limiting frames 630 at opposite positions. When the movable pulley 210 is in a lifting motion, the two limiting wheels 620 roll in opposite directions under the guidance of the limiting frames 630. This allows the two limiting frames 630 to guide the lifting motion of the movable pulley 210 through the two limiting wheels 620, thereby improving the stability of the movable pulley 210's lifting process while ensuring the smoothness of its rotation.

[0029] In other embodiments, two vertical grooves can be formed on the first bracket 100, allowing the two ends of the rotating shaft 610 to slide into them, thereby improving the lifting stability of the movable pulley 210. In other embodiments, two limiting grooves can be formed on the first bracket 100, allowing the two sides of the support frame 600 to slide into them, thereby limiting the lifting position of the support frame 600 and ensuring the lifting stability of the movable pulley 210.

[0030] The center height of the movable pulley 210 is lower than the height of the first fixed pulley 110. That is, when the drive impact cylinder 200 retracts to the shortest working length and drives the movable pulley 210 to rise to the highest position, the height of the movable pulley 210 is still lower than the height of the first fixed pulley 110. The height of the first fixed pulley 110 is the same as the height of the second fixed pulley 120.

[0031] One end of the rope 220 is fixed to the bottom of the top plate 101, and the other end passes over the bottom of the movable pulley 210, then over the top of the first fixed pulley 110, and then over the top of the second fixed pulley 120 before the impact hammer 230 is mounted on it. It can be understood that the position where the rope 220 is fixed to the top plate 101 is on the side of the impact cylinder 200 away from the first fixed pulley 110. Furthermore, the rotation center planes of the first fixed pulley 110, the second fixed pulley 120, and the movable pulley 210 coincide, thus keeping the rope 220 on the same rotation center plane after sequentially passing over the movable pulley 210, the first fixed pulley 110, and the second fixed pulley 120. This reduces the axial lateral pressure exerted by the rope 220 on the first fixed pulley 110, the second fixed pulley 120, and the movable pulley 210, which could affect the stability of the impact hammer 230.

[0032] When the output end of the driving impact cylinder 200 moves downward, the movable pulley 210 descends along with the output end of the impact cylinder 200, pushing the rope 220 to pull up the impact hammer 230. When the output end of the driving impact cylinder 200 moves upward, the movable pulley 210 rises along with the output end of the impact cylinder 200, and the rope 220 remains taut under the gravity of the impact hammer 230, causing the impact hammer 230 to fall and achieve the impact action of the impact hammer 230. The movable pulley can save half the stroke of the impact cylinder 200 and can speed up the movement of the movable pulley 210.

[0033] Furthermore, to improve the lifting and impact stability of the impact hammer 230, four guide rods 130 are vertically installed on the first bracket 100. A cover plate is installed on the top of the impact hammer 230, and the four guide rods 130 are respectively inserted at the four corners of the cover plate, and the four guide rods 130 are evenly arranged around the outer periphery of the impact hammer 230 to limit the movement of the impact hammer 230.

[0034] Furthermore, the battery pack disassembly equipment also includes two guide rails 400 and a second bracket 300. The two guide rails 400 are installed parallel to each other on the ground. The second bracket 300 has a drive wheel 401 and a follower wheel 402 mounted on its bottom near both sides of the two guide rails 400. The drive wheel 401 and follower wheel 402 on the same side roll together on the corresponding guide rail 400, allowing the second bracket 300 to slide relative to the guide rails 400.

[0035] A second driving component is mounted on the second bracket 300. The second driving component includes a transmission rod 412 and a second motor 411. The second motor 411 is mounted on the second bracket 300, and a first gear is mounted on the output end of the second motor 411. The transmission rod 412 is rotatably mounted on the second bracket 300, and a second gear is mounted on the transmission rod 412. The first gear and the second gear are meshed, allowing the second motor 411 to drive the transmission rod 412 to rotate through the transmission of the first gear and the second gear. The diameter of the first gear is smaller than the diameter of the second gear, so that the transmission action of the first gear and the second gear enables the second motor 411 to achieve deceleration and torque increase in driving the transmission rod 412.

[0036] The two ends of the transmission rod 412 are respectively close to the two guide rails 400, and a first synchronous pulley 413 is installed at both ends of the transmission rod 412. Each of the two drive wheels 401 is equipped with a second synchronous pulley 414 on the same shaft, meaning the drive wheel 401 rotates with the second synchronous pulley 414. The first synchronous pulley 413 and the second synchronous pulley 414, located on the same side, are fitted with a synchronous belt 415, so that the rotation of the first synchronous pulley 413 can drive the rotation of the second synchronous pulley 414. That is, when the second motor 411 is driven, it can drive the transmission rod 412 to rotate. After the first synchronous pulley 413 rotates with the transmission rod 412, it can drive the second synchronous pulley 414 to rotate via the synchronous belt 415, thereby driving the drive wheels 401 on both sides to rotate synchronously, pushing the second bracket 300 to move relative to the guide rails 400, thus realizing the movement of the second bracket 300.

[0037] The top of the second bracket 300 is equipped with two parallel sliding rods, and the bottom of the first bracket 100 is fitted onto the two sliding rods, allowing the first bracket 100 to slide along the length of the sliding rods on the second bracket 300. A first driving component is installed on the first bracket 100, which can drive the first bracket 100 to slide relative to the second bracket 300. The length direction of the sliding rods is perpendicular to the length direction of the guide rail 400, meaning the direction in which the first bracket 100 slides relative to the second bracket 300 is perpendicular to the direction in which the second bracket 300 slides relative to the guide rail 400, allowing the first bracket 100 to move relative to the guide rail 400 within a planar range.

[0038] Specifically, the first driving component includes a first motor 310, a transverse gear 311, and a rack 312. The first motor 310 is mounted on one side of the first bracket 100 with its output end facing downwards. The rack 312 is mounted laterally on the side of the second bracket 300 near the first motor 310, with its length parallel to the length of the slide rod. The transverse gear 311 is mounted on the output end of the first motor 310, and the transverse gear 311 meshes with the rack 312. When the first motor 310 is driven, it can drive the transverse gear 311 to rotate. Under the transmission action of the transverse gear 311 and the rack 312, the first bracket 100 moves relative to the second bracket 300.

[0039] Therefore, by driving the first motor 310, the first bracket 100 can be moved relative to the second bracket 300, and by driving the second motor 411, the second bracket 300 can be moved relative to the guide rail 400, i.e. the bottom surface. The two relative directions of movement are perpendicular to each other in space, which means that the first bracket 100 can be moved relative to the ground within a horizontal range, thereby adjusting the striking position of the impact hammer 230 within a horizontal range.

[0040] In other embodiments, the positions of the first motor 310 and the rack 312 can also be interchanged. That is, the rack 312 is mounted on the first bracket 100, and the first motor 310 is mounted on the second bracket 300. In order to ensure that the transverse gear and the rack 312 are not easily separated, the first motor 310 is located in the middle position on one side of the second bracket 300, and twice the length of the rack 312 is greater than the distance that the first bracket 100 moves relative to the second bracket 300.

[0041] It is understandable that both the first support 100 and the second support 300 have sufficient space for the impact hammer 230 to pass through, thereby preventing interference between the impact hammer 230 and the first support 100 and the second support 300.

[0042] Furthermore, the battery pack disassembly equipment also includes a third support 500, which comprises a first frame and a second frame that are separated from each other. The first frame and the second frame are mounted on the ground and are within the striking range of the impact hammer 230. Each of the first frame and the second frame is equipped with two clamping cylinders 510, with the output ends of the clamping cylinders 510 facing upwards and horizontally positioned pressure plates 511 mounted on their output ends. The two ends of the battery pack to be disassembled are supported on the top of the first frame and the second frame, respectively, and the clamping cylinders 510 drive the pressure plates 511 downwards to press down on the battery pack, thereby restricting the battery pack and facilitating the impact operation.

[0043] In summary, the working process of a battery pack disassembly device according to an embodiment of this application is as follows:

[0044] The second motor 411 moves the second bracket 300 away, placing the battery pack to be disassembled onto the third bracket. The clamping cylinder 510 clamps the battery pack between the pressure plate 511 and the third bracket 500. The second motor 411 and the first motor 310 then move the impact hammer 230, ensuring it covers the area above the battery pack to be struck during the entire striking process. During the striking process, the impact cylinder 200 drives the impact hammer 230 to repeatedly impact and strike the battery pack, breaking the frozen adhesive and causing the individual battery cells to detach, thus completing the disassembly of the battery pack. The movable pulley 210 reduces the stroke of the impact cylinder 200 by half, accelerating the lifting and lowering movement of the impact hammer 230 and improving the efficiency of the impact. Because the impact hammer 230 is restricted by the guide rod 130 and the movable pulley 210 is restricted by the limit frame, the impact process of the impact hammer 230 is very stable, resulting in high impact quality.

[0045] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
