Description

Technical Field

[0001] This invention relates to the field of power battery recycling, and in particular to a power battery module dismantling device and a power battery module dismantling method. Background Technology

[0002] In the recycling and production process of new energy power batteries, the dismantling of the power battery module base plate requires a significant amount of manpower and is considered a bottleneck in the production process. Typically, power batteries consist of multiple individual cells glued to the battery module base plate. The traditional method of dismantling power batteries involves manually cutting the individual cells off the base plate using handheld cutting equipment. However, this method is slow, inefficient, and the cutting equipment can easily damage the individual cells, thus affecting their recycling.

[0003] Therefore, there is an urgent need for a power battery module base plate disassembly device and method with high disassembly efficiency and without damaging individual battery cells. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a power battery module disassembly device and method that are highly efficient and have a low damage rate to individual battery cells.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A power battery module disassembly device, comprising:

[0007] frame;

[0008] A loading and unloading mechanism is mounted on the frame and is used to load and unload the power battery modules to be disassembled.

[0009] The two-sided clamping device is disposed on the frame and located on both sides of the loading and unloading mechanism. The two-sided clamping device is used to position the power battery module on the loading and unloading mechanism.

[0010] A bottom plate tearing and pressing device is movably mounted on the frame and located above the loading and unloading mechanism. The bottom plate tearing and pressing device is used to tear and separate the bottom plate of the power battery module from the battery cells.

[0011] A gripping mechanism is disposed on the frame and located above the loading and unloading mechanism. The gripping mechanism is used to grip the bottom plate from the bottom plate tearing and pressing device and onto the loading and unloading mechanism after the bottom plate is separated from the battery cell.

[0012] In one embodiment, the bottom plate tearing and pressing device includes a bottom plate tearing mechanism and a pressing and rolling mechanism;

[0013] The base plate tearing mechanism includes a driving assembly, a sliding frame, and a clamping assembly. The driving assembly is movably mounted on the frame, and its power output end is connected to the sliding frame. The clamping assembly is movably mounted on the sliding frame and is also connected to the power output end of the driving assembly. The driving assembly drives the sliding frame to slide relative to the frame in a first direction or a second direction. Simultaneously, when driving the sliding frame to slide in the first direction, it drives the clamping assembly to clamp the base plate, and when driving the sliding frame to slide in the second direction, it drives the clamping assembly to release the base plate. The first direction and the second direction are opposite.

[0014] The pressing and rolling mechanism is mounted on the sliding frame and is used to press and roll against the battery cells of the power battery module when the driving clamping assembly rotates in the forward direction.

[0015] In one embodiment, the driving assembly is used to drive the sliding frame to slide relative to the frame in a first direction when driving the clamping assembly to rotate in the forward direction, and to drive the sliding frame to slide relative to the frame in a second direction when driving the clamping assembly to rotate in the reverse direction;

[0016] When the driving assembly drives the clamping assembly to rotate in the positive direction, the driving assembly drives the sliding frame to slide in the first direction, the clamping assembly clamps and rolls up the base plate, and at the same time the pressing and rolling mechanism presses down and rolls against the battery cell.

[0017] When the driving drive assembly drives the clamping assembly to rotate in the opposite direction, the driving drive assembly drives the sliding frame to slide in the second direction, the gripping mechanism clamps one end of the base plate, and the clamping assembly releases the other end of the base plate.

[0018] In one embodiment, the clamping assembly includes a first clamping member, a second clamping member, and a first fixing part. The two ends of the first clamping member are rotatably connected to the first fixing part. The first clamping member is slidably connected to the sliding frame. The second clamping member is rotatably connected to the first fixing part and slidably connected to the sliding frame.

[0019] There are two first fixing parts. One of the first fixing parts is connected to the power output end of the driving drive component. The two first fixing parts are also rotatably connected to the sliding frame. Each first fixing part is provided with a first guide groove and a second guide groove. Both ends of the first clamping member are provided with a first guide shaft. Both ends of the second clamping member are provided with a second guide shaft. The first guide shafts at both ends of the first clamping member are slidably disposed in the first guide grooves of the two first fixing parts. The second guide shafts at both ends of the second clamping member are slidably disposed in the second guide grooves of the two first fixing parts.

[0020] The first clamping member is used to move closer to the second clamping member when the driving assembly rotates in the forward direction to jointly clamp the base plate; the first clamping member is also used to move further away from the second clamping member when the driving assembly rotates in the reverse direction to jointly release the base plate.

[0021] In one embodiment, the first clamping member includes a first rotating clamping part and two first guide sliders. The two ends of the first rotating clamping part are respectively connected to the two first guide sliders. The two first guide sliders are slidably connected in the sliding frame. The two first guide sliders are respectively fixedly connected to the first guide shaft.

[0022] In one embodiment, the second clamping member includes a second rotating clamping part and two second guide sliders. The two ends of the second rotating clamping part are respectively connected to the two second guide sliders. The two second guide sliders are slidably connected in the sliding frame. The two second guide sliders are respectively fixedly connected to the second guide shaft.

[0023] In one embodiment, both the first guide groove and the second guide groove are arc-shaped.

[0024] In one embodiment, the driving assembly includes a motor, a gear, and a rack. The rack is disposed on the top of the frame, the gear meshes with the rack, one end of the gear is rotatably connected to the sliding frame, and the other end of the gear is connected to the power output end of the motor.

[0025] In one embodiment, the gripping mechanism includes a feeding drive, two second fixing parts, a first feeding clamp and a second feeding clamp. The feeding drive is mounted on the frame, and the two second fixing parts are rotatably connected to the frame. One of the second fixing parts is connected to the power output end of the feeding drive. The two ends of the first feeding clamp are slidably connected to the two second fixing parts respectively.

[0026] The first unloading clamping member is used to move closer to the second unloading clamping member when the unloading drive member is driven to rotate in the forward direction, so as to clamp the base plate; the first unloading clamping member is also used to move further away from the second unloading clamping member when the unloading drive member is driven to rotate in the reverse direction, so as to release the base plate.

[0027] A method for disassembling a power battery module, comprising using the power battery module disassembly device described in any of the above embodiments to disassemble the base plate of the power battery module; the disassembly method includes:

[0028] The power battery module is pre-processed to make one end of the bottom plate of the power battery module tilt upwards.

[0029] The power battery module is loaded through the loading and unloading mechanism, wherein the raised end of the bottom plate of the power battery module is located near the clamping assembly.

[0030] The two sides of the power battery module are clamped by the clamping device on both sides.

[0031] Place one end of the raised bottom plate of the power battery module into the clamping position of the clamping assembly;

[0032] The driving component drives the clamping component to rotate in the positive direction, while the driving component drives the sliding frame to slide in the first direction. At the same time, the pressing and rolling mechanism presses down and rolls against the battery cell until the sliding frame slides relative to the frame to a preset position, so that the clamping component clamps and rolls up the base plate.

[0033] The gripping mechanism is controlled to clamp and fix the other end of the base plate located on the clamping assembly;

[0034] The clamping assembly is driven to rotate in the opposite direction by the driving assembly, and at the same time the driving assembly drives the sliding frame to slide in the second direction, so that the clamping assembly releases the base plate;

[0035] Control the gripping mechanism to release the base plate;

[0036] The disassembled power battery module is removed from the loading and unloading mechanism.

[0037] Compared with the prior art, the present invention has at least the following advantages:

[0038] In the aforementioned power battery module disassembly device, when the power battery module to be disassembled is placed on the loading and unloading mechanism, one end of the bottom plate of the power battery module is placed on the bottom plate tearing and pressing device. At this time, the device is activated, and the clamping devices on both sides and the bottom plate tearing and pressing device fix the power battery module. The bottom plate tearing and pressing device slides along the horizontal direction of the gripping mechanism, while simultaneously rotating to clamp the bottom plate. Since the battery cells are fixed in the corresponding positions by the clamping devices on both sides, and the bottom plate tearing and pressing device rolls against the battery cells, the horizontal direction of the bottom plate tearing upwards... The bottom plate moves horizontally relative to the battery cell in the tangential direction. The bottom plate moves along the horizontal direction of the gripping mechanism and exerts a force on the battery cell. When the bottom plate tearing and pressing device moves to the corresponding position, the bottom plate is torn off from the battery cell. This means that the bottom plate of the power battery module is disassembled using mechanized operations, which makes the disassembly efficiency of the module high. Furthermore, since there is no need to use cutting equipment to cut the bottom plate and the battery cell, the bottom plate can be separated from the battery cell attached to the bottom plate by simply using the clamping and tearing force, thus reducing the damage rate to the battery cell.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0050] This application provides a power battery module disassembly device, including a frame, a loading and unloading mechanism, two clamping devices on both sides, a bottom plate tearing and pressing mechanism, and a gripping mechanism. The loading and unloading mechanism is mounted on the frame and is used to load and unload the power battery module to be disassembled. The two clamping devices are mounted on the frame and located on both sides of the loading and unloading mechanism, and are used to position the power battery module within the loading and unloading mechanism. The bottom plate tearing and pressing device is movably mounted on the frame and located above the loading and unloading mechanism, and is used to tear and separate the bottom plate of the power battery module from the individual battery cells. The gripping mechanism is mounted on the frame and located above the loading and unloading mechanism, and is used to grip the bottom plate from the bottom plate tearing and pressing device onto the loading and unloading mechanism after the bottom plate has been separated from the individual battery cells.

[0051] In the aforementioned power battery module disassembly device, when the power battery module to be disassembled is placed on the loading and unloading mechanism, one end of the bottom plate of the power battery module is placed on the bottom plate tearing and pressing device. At this time, the device is activated, and the clamping devices on both sides and the bottom plate tearing and pressing device fix the power battery module. The bottom plate tearing and pressing device slides along the horizontal direction of the gripping mechanism, while simultaneously rotating to clamp the bottom plate. Since the battery cells are fixed in the corresponding positions by the clamping devices on both sides, and the bottom plate tearing and pressing device rolls against the battery cells, the horizontal direction of the bottom plate tearing upwards... The bottom plate moves horizontally relative to the battery cell in the tangential direction. The bottom plate moves along the horizontal direction of the gripping mechanism and exerts a force on the battery cell. When the bottom plate tearing and pressing device moves to the corresponding position, the bottom plate is torn off from the battery cell. This means that the bottom plate of the power battery module is disassembled using mechanized operations, which makes the disassembly efficiency of the module high. Furthermore, since there is no need to use cutting equipment to cut the bottom plate and the battery cell, the bottom plate can be separated from the battery cell attached to the bottom plate by simply using the clamping and tearing force, thus reducing the damage rate to the battery cell.

[0052] To better understand the technical solution and beneficial effects of this application, the following detailed description is provided in conjunction with specific embodiments:

[0053] like Figure 1 As shown, a power battery module disassembly device 10 according to one embodiment includes a frame 100, a loading / unloading mechanism 200, two-sided clamping devices 300, a gripping mechanism 600, and a bottom plate tearing and pressing device 700. The loading / unloading mechanism 200 is mounted on the frame 100 and is used to load and unload the power battery module to be disassembled. The two-sided clamping devices 300 are mounted on the frame 100 and are used to position the power battery module on the loading / unloading mechanism 200. The bottom plate tearing and pressing device 700 is movably mounted on the frame 100 and located above the loading / unloading mechanism 200, and is used to tear and separate the bottom plate of the power battery module from the battery cells. The gripping mechanism 600 is mounted on the frame 100 and located above the loading / unloading mechanism 200, and is used to grip the bottom plate from the bottom plate tearing and pressing device 700 onto the loading / unloading mechanism 200 after the bottom plate has been separated from the battery cells.

[0054] It is understandable that when the power battery module is placed in the loading and unloading mechanism, one end of the base plate is placed on the base plate tearing and pressing device 700. The clamping devices 300 on both sides fix the power battery module in the horizontal direction. At the same time, the base plate tearing and pressing device 700 presses down against the battery cell, exerting a force on the battery cell in the vertical direction. As the base plate tearing and pressing device 700 moves in the horizontal direction along the gripping mechanism 600, one end of the base plate is rotated and clamped by the base plate tearing and pressing device 700. The base plate moves with the base plate tearing and pressing device in the horizontal direction along the gripping mechanism 600. Since the battery cell is fixed in the corresponding position by the clamping devices 300 on both sides and the base plate tearing and pressing device 700, the base plate exerts a tearing force on the battery cell. When the base plate is clamped by the base plate tearing and pressing device 700 and moves to the corresponding position, the base plate is torn off the battery cell.

[0055] Furthermore, after the base plate is torn off from the battery cell, the other end of the base plate is placed on the gripping mechanism 600. At this time, the base plate tearing and pressing device 700 moves along a horizontal direction away from the gripping mechanism 600 and rotates to release the base plate. The gripping mechanism 600 rotates and clamps the base plate. When the base plate tearing and pressing device 700 is resetting, that is, when the base plate tearing and pressing device 700 is moving along its initial position, the base plate is transferred from the base plate tearing and pressing device 700 to the gripping mechanism 600.

[0056] In the aforementioned power battery module disassembly device 10, when the power battery module to be disassembled is placed on the loading and unloading mechanism 200, one end of the bottom plate of the power battery module is placed on the bottom plate tearing and pressing device 700. At this time, the device is activated, and the clamping devices 300 on both sides and the bottom plate tearing and pressing device 700 fix the power battery module. The bottom plate tearing and pressing device 700 slides along the horizontal direction where the gripping mechanism 600 is located. At the same time, the bottom plate tearing and pressing device 700 rotates to clamp the bottom plate. Since the battery cells are fixed in the corresponding positions by the clamping devices 300 on both sides, and the bottom plate tearing and pressing device 700 rolls and abuts against the battery cells. The bottom plate moves horizontally relative to the battery cell in the lateral tangential direction of the upward tearing motion. The bottom plate moves along the horizontal direction of the gripping mechanism 600 and exerts a force on the battery cell. When the bottom plate tearing and pressing device 700 moves to the corresponding position, the bottom plate is torn off the battery cell. This means that the bottom plate of the power battery module is disassembled using mechanized operations, which makes the disassembly efficiency of the module high. Furthermore, since there is no need to use cutting equipment to cut the bottom plate and the battery cell, the bottom plate can be separated from the battery cell attached to the bottom plate by simply using the clamping and tearing force, thus reducing the damage rate to the battery cell.

[0057] like Figures 1 to 3As shown, in one embodiment, the base plate tearing and pressing device 700 includes a base plate tearing mechanism 400 and a pressing and rolling mechanism 500. The base plate tearing mechanism 400 includes a driving assembly 410, a sliding frame 420, and a clamping assembly 430. The driving assembly 410 is movably mounted on the frame 100, and its power output end is connected to the sliding frame 420. The driving assembly 410 drives the sliding frame 420 to move relative to the frame 100 in a first direction or a second direction. It can be understood that the first direction is along the horizontal direction where the gripping mechanism 600 is located, and the second direction is away from the horizontal direction where the gripping mechanism 600 is located; the first direction and the second direction are opposite.

[0058] Furthermore, the clamping assembly 430 is movably disposed on the sliding frame 420. The clamping assembly 430 is also connected to the power output end of the driving assembly 410. The driving assembly 410 is used to drive the clamping assembly 430 to rotate in the forward or reverse direction, so that the clamping assembly 430 clamps or releases the base plate. The driving assembly 410 is also used to drive the sliding frame 420 to slide relative to the frame 100 in a first direction when the clamping assembly 430 is driven to rotate in the forward direction, that is, when the clamping assembly 430 is driven to rotate in the forward direction, the driving assembly 410 simultaneously drives the sliding frame 420 to slide relative to the frame 100 in the first direction; when the driving assembly 410 drives the clamping assembly 430 to rotate in the reverse direction, the driving assembly 410 drives the sliding frame 420 to slide relative to the frame 100 in a second direction opposite to the first direction, that is, when the clamping assembly 430 is driven to rotate in the reverse direction, the driving assembly 410 simultaneously drives the sliding frame 420 to slide relative to the frame 100 in a second direction opposite to the first direction.

[0059] Furthermore, the clamping assembly 430 is used to clamp or release the base plate of the power battery module; the pressing and rolling mechanism 500 is disposed on the frame 100, and the pressing and rolling mechanism 500 is used to press and roll against the battery cells of the power battery module when the driving clamping assembly 430 rotates in the forward direction; the gripping mechanism 600 is disposed on the frame 100, and the gripping mechanism 600 is used to clamp one end of the base plate when the driving drive assembly 410 drives the sliding frame 420 to slide relative to the frame 100 in the first direction to a preset position.

[0060] When the driving drive assembly 410 drives the clamping assembly 430 to rotate in the forward direction, the driving drive assembly 410 drives the sliding frame 420 to slide in the first direction, the clamping assembly 430 clamps and retracts the base plate, and at the same time the downward rolling mechanism 500 presses down and rolls against the battery cell; when the driving drive assembly 410 drives the clamping assembly 430 to rotate in the reverse direction, the driving drive assembly 410 drives the sliding frame 420 to slide in the second direction opposite to the first direction, and at the same time the gripping mechanism 600 clamps one end of the base plate, and the clamping assembly 430 releases the other end of the base plate.

[0061] In one embodiment, the loading / unloading mechanism 200 and the two-sided clamping devices 300 are located below the bottom plate tearing mechanism 400. The power battery module to be disassembled is placed in the loading / unloading mechanism 200, and one end of the bottom plate of the power battery module is placed in the clamping assembly 430. When the device is activated, the two-sided clamping devices 300 fix the battery cells and exert a horizontal force on the battery cells, so that the battery cells are fixed in the loading / unloading mechanism 200, that is, the battery cells will not move in the horizontal direction. At this time, the lower roller... When the driving mechanism 500 presses down, one end of the pressing and rolling mechanism 500 comes into contact with the battery cell, causing the pressing and rolling mechanism 500 to exert a force on the battery cell in the vertical direction, so that the battery cell will not move in the vertical direction. At the same time, when the driving component 410 moves along the first direction, that is, along the horizontal direction where the gripping mechanism 600 is located, the driving component 410 drives the clamping component 430 to rotate, that is, the clamping component 430 rotates in the positive direction, and the positive rotation of the clamping component 430 clamps one end of the base plate.

[0062] It is understandable that since the pressing and rolling mechanism 500 is connected to the sliding frame 420, and the sliding frame 420 is also movably connected to the driving drive component 410, when the driving drive component 410 moves horizontally, it drives the sliding frame 420 to move horizontally as well. That is, the pressing and rolling mechanism 500 also moves in the horizontal direction. Thus, when the pressing and rolling mechanism 500 moves horizontally, it continuously exerts a force on the battery cell in the vertical direction. That is, under the combined action of the clamping devices 300 on both sides and the pressing and rolling mechanism 500, the battery cell is fixed in the corresponding position.

[0063] Furthermore, the driving drive assembly 410 is connected to the clamping assembly 430. When the driving drive assembly 410 moves along the first direction, that is, along the horizontal direction where the gripping mechanism 600 is located, the driving drive assembly 410 drives the clamping assembly 430 to rotate, that is, the clamping assembly 430 rotates in the forward direction. The forward rotation of the clamping assembly 430 causes the clamping assembly 430 to clamp one end of the base plate. Since the battery cell is fixed in the corresponding position, the driving drive assembly 410 drives the clamping assembly 430 to move along the first direction. At this time, the clamping assembly 430 has a tearing force on the base plate. When the driving drive assembly 410 travels to the corresponding position, the base plate is completely torn off from the battery cell.

[0064] Furthermore, the gripping mechanism 600 is fixed to the frame 100. After the base plate is completely torn off by the clamping assembly 430, the other end of the base plate is placed in the gripping mechanism 600. The gripping mechanism 600 rotates forward under the drive of the motor, clamping the other end of the base plate. At this time, the driving assembly 410 begins to reset, that is, it moves in a second direction opposite to the first direction. The driving assembly 410 drives the clamping assembly 430 to rotate, and the clamping assembly 430 rotates in the opposite direction, releasing one end of the base plate. That is, the clamping assembly 430 and the gripping mechanism 600 rotate in opposite directions, releasing the first end of the base plate. At this time, the second end of the base plate is fixedly clamped to the gripping mechanism 600. As the driving assembly 410 travels to the initial position, the base plate on the clamping assembly 430 is transferred to the gripping mechanism 600 for clamping. Subsequently, the clamping assembly 430 moves to its initial position along with the sliding frame. After the base plate is transferred to the gripping mechanism 600, the motor is started to drive the gripping mechanism 600 to rotate in the opposite direction, thereby causing the base plate to fall off the gripping mechanism 600, completing the unloading operation of the base plate.

[0065] like Figures 2 to 4 As shown, in one embodiment, the clamping assembly 430 includes a first clamping member 431, a second clamping member 432, and a first fixing part 433. Both ends of the first clamping member 431 are rotatably connected to the first fixing part 433, and the first clamping member 431 is slidably connected to the sliding frame 420. The second clamping member 432 is rotatably connected to the first fixing part 433, and the second clamping member 432 is slidably connected to the sliding frame 420.

[0066] Furthermore, there are two first fixing parts 433. One of the first fixing parts 433 is connected to the power output end of the driving drive assembly 410, and the two first fixing parts 433 are also rotatably connected to the sliding frame 420. Each first fixing part 433 is provided with a first guide groove 434 and a second guide groove 435. The first clamping member 431 has a first guide shaft 436 protruding at both ends, and the second clamping member 432 has a second guide shaft 437 protruding at both ends. The first guide shafts 436 at both ends of the first clamping member 431 are slidably disposed in the first guide grooves 434 of the two first fixing parts 433, and the second guide shafts 437 at both ends of the second clamping member 432 are slidably disposed in the second guide grooves 435 of the two first fixing parts 433.

[0067] In one embodiment, the first clamping member 431 is configured to move closer to the second clamping member 432 when the driving drive assembly 410 rotates in a forward driving direction, so as to jointly clamp the base plate. The first clamping member 431 is also configured to move further away from the second clamping member 432 when the driving drive assembly 410 rotates in a reverse driving direction, so as to jointly release the base plate.

[0068] In this embodiment, both the first clamping member 431 and the second clamping member 432 are semi-cylindrical in shape. The two ends of the first clamping member 431 and the two ends of the second clamping member 432 are rotatably connected to the two first fixing parts 433 respectively. The two first fixing parts 433 are provided with a first guide groove 434 and a second guide groove 435. The two ends of the first clamping member 431 are provided with a first guide shaft 436, which is slidably disposed in the first guide groove 434 of the two first fixing parts 433. The two ends of the second clamping member 432 are also provided with a second guide shaft 437, which is slidably disposed in the second guide groove 435 of the two first fixing parts 433.

[0069] Furthermore, when the driving assembly 410 moves in the first direction, it drives the clamping assembly 430 to rotate in the forward direction. The first guide shaft 436 slides in the forward direction in the first guide groove 434, while the second guide shaft 437 slides in the forward direction in the second guide groove 435, causing the first clamping member 431 and the second clamping member 432 to move closer to each other, thereby clamping the base plate. When the driving assembly 410 moves in the second direction, it drives the clamping assembly 430 to rotate in the reverse direction. The first guide shaft 436 slides in the reverse direction in the first guide groove 434, while the second guide shaft 437 slides in the reverse direction in the second guide groove 435, causing the first clamping member 431 and the second clamping member 432 to move further apart, thereby releasing the base plate.

[0070] like Figure 2 and Figure 3 As shown, in one embodiment, the first clamping member 431 includes a first rotating clamping part 438 and two first guide sliders 439. The two ends of the first rotating clamping part 438 are respectively connected to the two first guide sliders 439. The two first guide sliders 439 are slidably connected in the sliding frame 420. The two first guide sliders 439 are respectively fixedly connected to the first guide shaft 436.

[0071] It is understandable that, since the power output end of the driving drive assembly 410 is rotatably connected to one of the first fixed parts 433, the first guide slider 439 is slidably connected in the sliding frame 420, and the two first guide sliders 439 are respectively fixedly connected to the first guide shaft 436, when the driving drive assembly 410 moves along the first direction, that is, along the horizontal direction where the gripping mechanism 600 is located, the first guide shaft 436 connecting the two first guide sliders 439 slides forward along the extension direction of the first guide groove 434, so that the two first guide sliders 439 move in the horizontal direction where the two second guide sliders 441 are located; similarly, the second guide shaft 437 connecting the two second guide sliders 441 slides forward along the extension direction of the second guide groove 435, so that the two second guide sliders 441 move in the horizontal direction where the two first guide sliders 439 are located. In this way, the first rotating clamping part 438 connected to the two first guide sliders 439 and the second rotating clamping part 440 connected to the two second guide sliders 441 move towards each other, thereby clamping the base plate.

[0072] Furthermore, when the driving drive assembly 410 moves along the second direction, that is, along the horizontal direction opposite to the first direction, the first guide shaft 436 connecting the two first guide sliders 439 slides in the opposite direction along the extension direction of the first guide groove 434, causing the two first guide sliders 439 to move in the horizontal direction away from the two second guide sliders 441. Similarly, the second guide shaft 437 connecting the two second guide sliders 441 slides in the opposite direction along the extension direction of the second guide groove 435, causing the two second guide sliders 441 to move in the horizontal direction away from the two first guide sliders 439. In this way, the first rotating clamping part 438 connected to the two first guide sliders 439 and the second rotating clamping part 440 connected to the two second guide sliders 441 move in opposite directions, thereby releasing the base plate.

[0073] like Figure 2 and Figure 3As shown, in one embodiment, the second clamping member 432 includes a second rotating clamping part 440 and two second guide sliders 441. The two ends of the second rotating clamping part 440 are respectively connected to the two second guide sliders 441. The two second guide sliders 441 are slidably connected in the sliding frame 420. The two second guide sliders 441 are respectively fixedly connected to the second guide shaft 437. When each second guide slider 441 and the corresponding first guide slider 439 slide towards each other in the corresponding sliding frame 420, the first rotating clamping part 438 and the second rotating clamping part 440 move closer to each other and clamp the base plate together. When each second guide slider 441 and the corresponding first guide slider 439 slide away from each other in the corresponding sliding frame 420, the first rotating clamping part 438 and the second rotating clamping part 440 move away from each other and release the base plate together. Thus, as the first guide shaft 436 slides along the first guide groove 434 and the second guide shaft 437 slides along the second guide groove 435, the base plate is clamped or released, while avoiding the problem of the sliding frame rotating. This ensures that the pressing and rolling mechanism 500 can always reliably press down on the surface of the battery cell, so that the base plate can be reliably separated from the battery cell, thereby realizing the reliable disassembly of the power battery module.

[0074] It can be understood that when the driving component 410 moves along the first direction, that is, along the horizontal direction where the gripping mechanism 600 is located, the second guide shaft 437 connecting the two second guide sliders 441 slides forward along the extension direction of the second guide groove 435, causing the two second guide sliders 441 to move in the horizontal direction where the two first guide sliders 439 are located. Similarly, the first guide shaft 436 connecting the two first guide sliders 439 slides forward along the extension direction of the first guide groove 434, causing the two first guide sliders 439 to move in the horizontal direction where the two second guide sliders 441 are located. In this way, the second clamping member 432 connected to the two second guide sliders 441 and the first rotating clamping part 438 connected to the two first guide sliders 439 move towards each other, thereby clamping the base plate.

[0075] Furthermore, when the driving drive assembly 410 moves along the second direction, that is, along the horizontal direction opposite to the first direction, the second guide shaft 437 connecting the two second guide sliders 441 slides in the opposite direction along the extension direction of the second guide groove 435, causing the two second guide sliders 441 to move in the horizontal direction away from the two first guide sliders 439; similarly, the first guide shaft 436 connecting the two first guide sliders 439 slides in the opposite direction along the extension direction of the first guide groove 434, causing the two first guide sliders 439 to move in the horizontal direction away from the two second guide sliders 441. In this way, the first clamping member 431 connected to the two first guide sliders 439 and the second rotating clamping part 440 connected to the two second guide sliders 441 move in opposite directions, thereby releasing the base plate.

[0076] like Figure 4 As shown, in one embodiment, both the first guide groove 434 and the second guide groove 435 are arc-shaped. It can be understood that the first guide shaft 436 is disposed within the first guide groove 434, and the second guide shaft 437 is disposed within the second guide groove 435. The first guide shaft 436 slides forward or backward along the extending direction of the first guide groove 434, while the second guide shaft 437 correspondingly slides forward or backward along the extending direction of the second guide groove 435, causing the first rotating clamping part 438 and the second rotating clamping part 440 to move closer and further apart, thereby causing the clamping assembly 430 to clamp or release the base plate. In this embodiment, both the first guide groove 434 and the second guide groove 435 are arc-shaped.

[0077] like Figure 5 As shown, in one embodiment, the driving assembly 410 includes a motor 411, a gear 412, and a rack 413. The rack 413 is disposed on the top of the frame 100, and the gear 412 meshes with the rack 413. One end of the gear 412 is rotatably connected to the sliding frame 420, and the other end of the gear 412 is connected to the power output end of the motor 411, so that the driving assembly 410 drives the sliding frame to move relative to the frame, and at the same time drives the clamping assembly to rotate, that is, drives the clamping assembly to clamp or release the base plate. It can be understood that under the drive of the motor 411, the gear 412 moves along a first direction or a second direction. When the gear 412 moves along the first direction, the clamping assembly 430 rotates in the forward direction to clamp one end of the base plate and moves along the first direction, so that the base plate is torn off; when the gear 412 moves along the second direction, the clamping assembly 430 rotates in the reverse direction to release one end of the base plate and moves along the second direction, so that one end of the base plate falls off the clamping assembly 430.

[0078] like Figure 5As shown, in one embodiment, the downward rolling mechanism 500 includes a vertical telescopic cylinder 510, a vertical infrared sensor 520, and a rolling wheel 530. The vertical telescopic cylinder 510 is mounted on the sliding frame 420, and the output end of the vertical telescopic cylinder 510 is connected to the rolling wheel 530. The vertical infrared sensor 520 is electrically connected to the control end of the vertical telescopic cylinder 510. The vertical telescopic cylinder 510 is used to drive the rolling wheel 530 to move to a predetermined height position when the vertical infrared sensor 520 senses the power battery module. It is understood that when the device is started, the vertical infrared sensor 520 senses the position of the power battery module and releases a signal to cause the vertical telescopic cylinder 510 to press down, and the rolling wheel 530 abuts against the battery cell. Since the rolling wheel 530 is connected to the sliding frame 420, that is, when the sliding frame 420 moves in the first direction, the rolling wheel 530 also moves in the first direction. That is, during the tearing operation, the clamping assembly 430 continuously applies force to the battery cell so that the battery cell will not lift up during the tearing process of the base plate.

[0079] like Figure 1 As shown, in one embodiment, both the base plate tearing mechanism 400 and the gripping mechanism 600 are located at the top of the frame 100, enabling the disassembly device to easily disassemble the base plate of the module, while also making the structural design of the insertion device more reasonable. It is understood that in other embodiments, the base plate tearing mechanism 400 and the gripping mechanism 600 are not limited to being located at the top of the frame 100. For example, the base plate tearing mechanism 400 and the gripping mechanism 600 may also be located at the bottom of the frame 100.

[0080] like Figure 6 As shown, in one embodiment, the gripping mechanism 600 includes a feeding drive 610, two second fixing parts 620, a first feeding clamping part 630, and a second feeding clamping part 640. The feeding drive 610 is mounted on the frame 100. Both second fixing parts 620 are rotatably connected to the frame 100, and one of the second fixing parts 620 is connected to the power output end of the feeding drive 610. The two ends of the first feeding clamping part 630 are slidably connected to the two second fixing parts 620 respectively. The first feeding clamping part 630 is used to move closer to the second feeding clamping part 640 when the feeding drive 610 rotates in the forward direction to clamp the base plate; the first feeding clamping part 630 is also used to move further away from the second feeding clamping part 640 when the feeding drive 610 rotates in the reverse direction to release the base plate.

[0081] It is understood that the gripping mechanism 600 is fixed on the frame 100, and the two ends of the first unloading clamping member 630 and the two ends of the second unloading clamping member 640 are slidably connected to the two second fixing parts 620 respectively. After the base plate is torn off from the battery cell, the other end of the base plate is placed in the clamping position between the first unloading clamping member 630 and the second unloading clamping member 640. When the clamping assembly 430 moves in the second direction, the unloading drive member 610 drives the first unloading clamping member 630 and the second unloading clamping member 640 to rotate in the forward direction, so that the first unloading clamping member 630... The first and second unloading clamping members 630 and 640 move closer together to clamp the base plate. During the forward rotation of the first and second unloading clamping members 630 and 640, the base plate is wound from the clamping members onto the first and second unloading clamping members 630 and 640. When the base plate is completely wound onto the gripping mechanism 600, the unloading drive member 610 drives the first and second unloading clamping members 630 and 640 to rotate in opposite directions so that the second and second unloading clamping members 640 move away from each other, thereby releasing the base plate.

[0082] This application also provides a method for disassembling a power battery module, which involves using the power battery module disassembly device described in any of the above embodiments to disassemble the base plate of the power battery module. Further, the disassembly method includes:

[0083] S101. Pre-process the power battery module to raise one end of the base plate of the power battery module. This can be understood as raising one end of the base plate of the power battery module through mechanical operation.

[0084] S103. The power battery module is loaded via the loading and unloading mechanism, wherein the raised end of the base plate of the power battery module is located near the clamping assembly. It can be understood that the untreated end of the base plate, i.e., the end of the base plate that is not raised, enters the loading and unloading mechanism first.

[0085] S105. The two sides of the power battery module are clamped by the clamping device on both sides.

[0086] like Figure 6 As shown, in this embodiment, the clamping device 300 includes a horizontal infrared sensor 310, two side fixing members 330, and a horizontal telescopic cylinder 320. The horizontal infrared sensor 310 is electrically connected to the horizontal telescopic cylinder 320, and the power output end of the horizontal telescopic cylinder 320 is connected to the two side fixing members 310. When the power battery module to be disassembled enters the loading and unloading mechanism, the horizontal infrared sensor 310 releases a signal to drive the horizontal telescopic cylinder 320 to drive the two side fixing members 330 to fix the battery cells of the power battery module.

[0087] S107. Place one end of the raised bottom plate of the power battery module into the clamping position of the clamping assembly. This can be understood as placing the raised end of the pre-treated bottom plate into the clamping position of the clamping assembly, i.e., within the material passage.

[0088] S109. The driving drive assembly drives the clamping assembly to rotate in the forward direction, while simultaneously driving the sliding frame to slide in the first direction. At the same time, the downward rolling mechanism presses down and rolls against the battery cell until the sliding frame slides relative to the frame to a preset position, causing the clamping assembly to clamp and retract the base plate. It can be understood that the driving drive assembly and the clamping assembly are rotatably connected. When the driving drive assembly slides in the first direction, the clamping component rotates in the forward direction to clamp and retract the base plate. Simultaneously, the downward rolling mechanism presses down and rolls against the surface of the battery cell, so that during the process of the clamping assembly tearing the base plate, the downward rolling mechanism continuously applies force to the battery cell in the vertical direction to prevent the battery cell from tilting.

[0089] S111, The gripping mechanism is controlled to clamp and fix the other end of the base plate located on the clamping assembly. It can be understood that the gripping mechanism rotates in the forward direction under the drive of the motor so as to clamp the other end of the base plate.

[0090] S113. The driving drive assembly drives the clamping assembly to rotate in the opposite direction, while simultaneously driving the sliding frame to slide in the second direction, so that the clamping assembly releases the base plate. It can be understood that the driving drive assembly drives the clamping assembly to rotate in the opposite direction, causing the clamping assembly to release one end of the base plate, while the gripping mechanism rotates in the forward direction, causing the gripping mechanism to clamp and wrap around the other end of the base plate. That is, the clamping assembly and the gripping mechanism rotate in opposite directions, thereby causing the base plate to wrap around the gripping mechanism.

[0091] S115. Control the gripping mechanism to release the base plate. This can be understood as the motor driving the gripping mechanism to rotate in the opposite direction, causing the gripping mechanism to release the base plate.

[0092] S117. Remove the disassembled power battery module from the loading and unloading mechanism.

[0093] Compared with the prior art, the present invention has at least the following advantages:

[0094] In the aforementioned power battery module disassembly device, when the power battery module to be disassembled is placed on the loading and unloading mechanism, one end of the bottom plate of the power battery module is placed on the bottom plate tearing and pressing device. At this time, the device is activated, and the clamping devices on both sides and the bottom plate tearing and pressing device fix the power battery module. The bottom plate tearing and pressing device slides along the horizontal direction of the gripping mechanism, while simultaneously rotating to clamp the bottom plate. Since the battery cells are fixed in the corresponding positions by the clamping devices on both sides, and the bottom plate tearing and pressing device rolls against the battery cells, the horizontal direction of the bottom plate tearing upwards... The bottom plate moves horizontally relative to the battery cell in the tangential direction. The bottom plate moves along the horizontal direction of the gripping mechanism and exerts a force on the battery cell. When the bottom plate tearing and pressing device moves to the corresponding position, the bottom plate is torn off from the battery cell. This means that the bottom plate of the power battery module is disassembled using mechanized operations, which makes the disassembly efficiency of the module high. Furthermore, since there is no need to use cutting equipment to cut the bottom plate and the battery cell, the bottom plate can be separated from the battery cell attached to the bottom plate by simply using the clamping and tearing force, thus reducing the damage rate to the battery cell.

[0095] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
