For this type of battery module, the disassembly of the end-side panels mainly relies on grinding wheel cutting and manual peeling, which leads to low safety and work efficiency in the disassembly process and high disassembly costs.

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

[0052] The present application provides a battery module end and side panel disassembly device, comprising a mounting frame, a conveying mechanism, and a rotary pressing and peeling mechanism. The rotary pressing and peeling mechanism is arranged on the mounting frame, and comprises a pressing assembly, a rotating plug assembly, and a rotating platform assembly. The pressing assembly and the rotating plug assembly are both connected to the mounting frame, and the rotating platform assembly is rotatably connected to the mounting frame. The pressing assembly is used to press down and tighten the battery module, and the rotating plug assembly is used to plug into the through hole of the battery module and then move horizontally to initially separate the end plate and side panel of the battery module. The rotating plug assembly is also used to rotate and rotate after horizontal movement to completely peel off the end plate and side panel of the battery module. The conveying mechanism is arranged on the mounting frame, and the conveying mechanism is used to convey the battery module to the rotary pressing and peeling mechanism.

[0053] The battery module end and side panel disassembly device described above places the battery module to be disassembled on a conveying mechanism, which then transfers the battery module to a rotating platform assembly. The pressing assembly then presses down on the battery module, and after the pressing is complete, the active end of the rotating plug assembly plugs into the through-hole of the battery module. After the plugging is complete, the rotating plug assembly rotates until the end and side panels of the battery module are completely separated. The operating procedures of the device described above allow for complete separation of the end and side panels of the battery module, i.e., a fully streamlined operation without manual intervention, thereby avoiding safety issues during manual disassembly and improving disassembly efficiency.

[0054] To better understand the technical solutions and beneficial effects of the present application, the present application is further described in detail below with reference to specific embodiments:

[0055] As shown in Figure 1, a battery module end panel disassembly device 10 according to one embodiment includes a mounting frame 100, a conveying mechanism 10a, and a rotary, downward-pressing, and peeling mechanism 400. The conveying mechanism 10a is disposed on the mounting frame 100 and is used to convey the battery module to the rotary, downward-pressing, and peeling mechanism 400. Furthermore, the rotary downward pressure peeling mechanism 400 is arranged on the mounting frame 100, and the rotary downward pressure peeling mechanism 400 includes a downward pressure component 410, a rotary plug-in component 420 and a rotary platform component 430. The downward pressure component 410 and the rotary plug-in component 420 are both connected to the mounting frame 100, and the rotary platform component 430 is rotatably connected to the mounting frame 100. The downward pressure component 420 is used to press down and tighten the battery module. The rotary plug-in component 420 is used to plug into the corresponding through hole on the battery module and then move horizontally, so that the end plate and the side plate of the battery module are initially separated, and then the rotary plug-in component 420 rotates to completely peel off the end plate and the side plate of the battery module.

[0056] In this embodiment, before the battery module is placed on the conveying mechanism 10a, the welding positions of the end plates and side plates of the battery module must be pre-processed first to separate the edges of the end plates and side plates from each other; preferably, the welding positions of the end plates and side plates are cut first. After the pre-processing is completed, the end plates and side plates are still bonded together. At this time, the active end of the rotating plug-in component 420 is plugged into the through hole of the end plate and moves horizontally for a period of time. Under the action of tension, a gap is formed between the end plate and the side plate. The rotating plug-in component 420 is then rotated to completely separate the end plate from the side plate. This eliminates the need for manual operation, thereby improving safety and efficiency. Preferably, the horizontal movement distance of the rotating plug-in component 420 can be pre-set by a program.

[0057] The battery module end and side panel disassembly device 10 described above places the battery module to be disassembled on the conveying mechanism 10a, which transfers the battery module to the rotating platform assembly 430. At this time, the pressing assembly 410 presses down and compacts the battery module. After compaction, the active end of the rotating plug assembly 420 plugs into the through hole of the battery module. After plugging, the rotating plug assembly 420 rotates until the end and side panels of the battery module are completely peeled off. The operating procedures of the above-mentioned device can achieve complete peeling of the end and side panels of the battery module, that is, full assembly line operation without manual participation, thereby avoiding safety issues in the manual disassembly process and improving disassembly efficiency.

[0058] As shown in Figures 1 and 3, in one embodiment, the downward pressure assembly 410 includes a first connecting frame 411, a first horizontal driving member 412, a first vertical driving member 413, a clamping plate 414, a rotational reset driving member 415 and a slide rail 416, the slide rail 416 is installed on the mounting frame 100, the first connecting frame 411 is slidingly connected to the slide rail 416, the first horizontal driving member 412 is installed on the mounting frame 100, the first connecting frame 411 is installed at the power output end of the first horizontal driving member 412, the first vertical driving member 413 is installed on the first connecting frame 411, the rotational reset driving member 415 is connected to the power output end of the first vertical driving member 413, and the clamping plate 414 is rotatably connected to the power output end of the rotational reset driving member 415.

[0059] In this embodiment, before the battery module is peeled off, the battery module is first centered. After the centering is completed, the first horizontal drive member 412 drives the first connecting frame 411 to move horizontally on the slide rail so that the clamping plate 414 can move to the corresponding position above the battery module. At this time, the first vertical drive member 413 drives the clamping plate 414 downwardly against the battery module, so that the clamping plate 414 exerts pressure on the battery module to fix the battery module. Furthermore, the clamping plate rotates together under the rotation drive of the rotating plug-in assembly 420. After each rotation and peeling of the end and side plates of the battery module is completed, the position of the clamping plate 414 is not fixed and is in an arbitrary position. Therefore, before each compression and fixation of the battery module, the rotary reset drive member 415 will rotate and reset the clamping plate 414 to ensure that the initial position of the clamping plate 414 is fixed each time. Furthermore, according to the different sizes of battery modules, the pressing plates 414 of different specifications can be replaced to improve the adaptability of the battery module end plate disassembly device 10. In this embodiment, the first horizontal driving member 412 and the first vertical driving member 413 are motors or cylinders, and the rotation reset driving member 415 is a motor.

[0060] As shown in Figures 1, 3, 4 and 8, in one embodiment, the rotating plug-in assembly 420 includes a second connecting frame 421, a second horizontal driving member 422, a second vertical driving member 423, a rotating driving device 424, a connector 425 and a rear-pull driving member 426. The second connecting frame 421 is slidably arranged on the mounting frame 100. The second connecting frame 421 is respectively connected to the second horizontal driving member 422 and the rotating driving device 424. The second connecting frame 421 is also connected to the second vertical driving member 423. The rear-pull driving member 426 is installed on the second connecting frame 421. The connector 425 is connected to the power output end of the rotating driving device 424. The connector 425 is used to be plugged into the through hole of the battery module.

[0061] It can be understood that the connector 425 is inserted into the through-hole of the battery module end plate under the drive of the second horizontal drive member 422 and the second vertical drive member 423. The second horizontal drive member 422 then moves horizontally, generating a force between the battery end plate and the side plate, thereby initially separating the end plate from the side plate. After the end plate and the side plate are initially separated, the rotation drive device 424 drives the connector 425 to rotate, and the external pulling and winding forces completely tear the end plate and the side plate off. In this embodiment, the second horizontal drive member 422, the second vertical drive member 423, the rotation drive device 424, and the rear pull drive member 426 are all motors.

[0062] As shown in Figure 8, in one embodiment, the second connecting frame 421 includes a longitudinal connecting portion 4211 and a transverse connecting portion 4212, the longitudinal connecting portion 4211 is movably connected to the transverse connecting portion 4212, the longitudinal connecting portion 4211 is respectively connected to the second horizontal driving member 422 and the second vertical driving member 423, and the transverse connecting portion 4212 is respectively connected to the rear pulling driving member 426 and the rotation driving device 424.

[0063] It can be understood that the connector 425 is connected to the power output end of the rotary drive device 424, which is movably connected to the transverse connection portion 4212. The second horizontal drive member 422 drives the longitudinal connection portion 4211 to move horizontally, thereby driving the transverse connection portion 4212 to move horizontally, that is, the rotary drive device 424 also moves horizontally. At the same time, the second vertical drive member 423 drives the transverse connection portion 4212 to move in the vertical direction, that is, the rotary drive device 424 also moves in the vertical direction, so that the connector 425 can be accurately inserted into the end plate through-hole of the battery module. Furthermore, after the connector 425 is inserted into the end plate through-hole of the battery module, the second horizontal drive member 422 drives the longitudinal connection portion 4211 to move in the X direction, and the rear pull drive member 426 drives the rotary drive device to move in the Y direction, causing the connector connected to the rotary drive device to move horizontally in the Z direction for a period of time. Under the action of the pulling force, the end side plates of the battery module are initially separated. Furthermore, after the end and side plates of the battery module are initially separated, the rotary drive device 424 rotates, thereby driving the connector 425 to rotate, so that the end and side plates of the battery module are completely peeled off under the action of the rotation.

[0064] As shown in Figure 8, in one embodiment, the rotating platform assembly 430 includes a rotating platform 431, a rotating bracket 432, a rotating drive member 433 and a locking drive member 434, the rotating bracket 432 is connected to the mounting bracket 100, the power output end of the rotating drive member 433 is connected to the rotating bracket 432, the locking drive member 434 is connected to the mounting bracket 100, and the locking drive member 434 is also movably connected to the rotating bracket 432, and the rotating platform 431 is connected to the rotating bracket 432.

[0065] It can be understood that the battery module is pressed down and fixed on the rotating platform 431 by the clamping plate 414. When the end plate is initially separated from the side plate, that is, when the rotating plug assembly 420 moves horizontally, the clamping plate 414 and the rotating platform 431 remain relatively stationary, and under the action of the external pull, the end plate and the side plate are initially separated. Furthermore, when the rotating plug assembly 420 rotates, the locking drive member 434 moves to allow the rotating bracket 432 to rotate, and then the rotating platform 431 and the clamping plate 414 rotate under the drive of the rotating plug assembly 420, so that the end plate and the side plate are completely separated. In this embodiment, the rotating drive member 433 can be a servo motor or a rotary cylinder.

[0066] As shown in FIG6 , in one embodiment, the rotating bracket 432 is provided with an embedding groove 4321 , and the locking drive member 434 includes a driving portion 4341 and a locking block 4342 . The power output end of the driving portion 4341 is connected to the locking block 4342 , and the locking block 4342 is located in the embedding groove 4321 . The driving portion 4341 drives the locking block 4342 to embed into or move away from the embedding groove 4321 .

[0067] When the driving part 4341 drives the locking block 4342 away from the embedding groove 4321, the rotating plug-in assembly 420 drives the rotating bracket 432 to rotate relative to the mounting frame 100; when the driving part 4341 drives the locking block 4342 to be inserted into the embedding groove 4321, the rotating bracket 432 is stationary relative to the mounting frame 100.

[0068] It will be appreciated that when the rotary plug assembly 420 rotates, the driver 4341 drives the locking block 4342 out of the embedding groove 4321, allowing the rotary bracket 432 to rotate. When the end plate and the side plate are completely separated, the rotary driver 433 drives the rotary bracket 432 to return to its original position. After the rotary bracket 432 is restored, the driver 4341 drives the locking block 4342 to return to its original position, returning the locking block 4342 to its original position within the embedding groove 4321. In this embodiment, the driver 4341 may be a pneumatic cylinder or a linear motor.

[0069] As shown in FIG1 and FIG2 , in one embodiment, the battery module end side plate device further includes a peeling and positioning mechanism 600, which is provided on the mounting frame 100. The peeling and positioning mechanism 600 is provided corresponding to the rotating downward pressing peeling mechanism 400, and is used to peel and position the battery module on the rotating downward pressing peeling mechanism 400;

[0070] The peeling positioning mechanism 600 includes a plurality of positioning drive components 610 arranged vertically and horizontally in the horizontal plane direction, each of the positioning drive components 610 includes a third horizontal drive member 611, a third vertical drive member 612 and a positioning push block 613, and the positioning push block 613 is respectively connected to the power output ends of the third horizontal drive member 611 and the third vertical drive member 612, and the third horizontal drive member 611 and the third vertical drive member 612 are both connected to the mounting frame 100.

[0071] It is understood that before the rotating plug assembly 420 is inserted into the through-hole of the battery module, the stripping and positioning mechanism 600 first centers the battery module on the rotating platform 431 to make it easier for the rotating plug assembly 420 to be inserted into the through-hole of the battery module. First, the third vertical drive member 612 drives the positioning push block 613 to move up and down, so that the positioning push block 613 and the battery module are at the same horizontal position. Then, the third horizontal drive member 611 drives the positioning push block 613 to move horizontally, thereby positioning the battery module in the center of the rotating platform 431. In this embodiment, the third vertical drive member 612 can be a motor or a cylinder, and the third horizontal drive member 611 can be a motor or a cylinder.

[0072] As shown in Figures 1 and 2, in one embodiment, there are four positioning drive assemblies 610, and the four positioning drive assemblies 610 are symmetrically arranged in pairs relative to the rotating platform 431. It can be understood that two of the positioning drive assemblies 610 are located on the length centerline of the rotating platform 431, and the other two positioning drive assemblies 610 are located on the width centerline of the rotating platform 431. Under the push of the four positioning drive assemblies 610, the battery module is pushed to the center position of the rotating platform 431, so that the connector 425 in the subsequent process can be more easily inserted into the through hole of the end plate.

[0073] As shown in Figure 1, in one embodiment, the conveying mechanism 10a includes a conveyor belt mechanism 200 and a clamping moving mechanism 500. The conveyor belt mechanism 200 is arranged below the mounting frame 100, and the conveyor belt mechanism 200 is used to transport the battery module to be disassembled; the clamping moving mechanism 500 is slidably arranged on the mounting frame 100, and the clamping moving mechanism 500 is used to clamp the battery module after the correction mechanism 300 is positioned to the rotating downward pressing stripping mechanism 400.

[0074] It can be understood that the battery module is placed on the conveyor belt mechanism 200 for transportation. When the battery module is transported to the corresponding position, the conveyor belt mechanism 200 stops operating. At this time, the clamping moving mechanism 500 moves to the top of the battery module, and the active end of the clamping moving mechanism 500 moves downward to clamp the battery module, and finally the battery module is clamped onto the rotating platform 431.

[0075] As shown in Figure 7, in one embodiment, the mounting frame 100 is provided with a sliding guide rail 120, and the clamping moving mechanism 500 is slidably set on the sliding guide rail 120. The sliding guide rail 120 is extended along the direction of the conveyor belt mechanism 200 and the rotating downward pressing stripping mechanism 400, so that the clamping moving mechanism 500 slides to the corresponding position to clamp the battery module, and then continues to slide above the rotating downward pressing stripping mechanism 400, thereby clamping the battery module to the rotating platform 431.

[0076] As shown in Figure 7, in one embodiment, the clamping moving mechanism 500 includes a moving frame 510, a clamping assembly 520, a fourth horizontal driving member 530 and a fourth vertical driving member 540, the moving frame 510 is slidably set on the sliding guide rail 120, the moving frame 510 is connected to the power output end of the fourth horizontal driving member 530, the fourth vertical driving member 540 is installed on the moving frame 510, and the power output end of the fourth vertical driving member 540 is connected to the clamping assembly 520.

[0077] It can be understood that the movable frame 510 is slidably disposed on the sliding guide rail 120, and the fourth horizontal driving member 530 drives the movable frame 510 to move horizontally. When the movable frame 510 moves above the battery module, the fourth vertical driving member 540 drives the clamping assembly 520 to move downward, so that the clamping assembly 520 contacts the battery module. At this time, the clamping driving member 521 drives the clamping assembly 520 to clamp the battery module. Driven by the fourth horizontal driving member 530, the battery module continues to move horizontally to the rotating platform 431. In this embodiment, the fourth horizontal driving member 530 can be a motor, and the fourth vertical driving member 540 can be a motor.

[0078] As shown in Figure 7, in one embodiment, the clamping assembly 520 includes a clamping drive 521 and two clamping plates 522, the clamping drive 521 is connected to the power output end of the fourth vertical drive 540, and the two clamping plates 522 are connected to the clamping drive 521 so that the two clamping plates 522 move away from or closer to each other under the drive of the clamping drive 521.

[0079] It can be understood that when the clamping driver 521 drives the two clamping plates 522 toward each other, the battery module is fixed between the two clamping plates 522; when the clamping driver 521 drives the two clamping plates 522 away from each other, the battery module is released, thereby achieving the function of the clamping assembly 520 to clamp the battery module. Furthermore, the clamping driver 521 can drive the two clamping plates 522 toward each other or away from each other, adapting to battery modules of different models and sizes. In this embodiment, the clamping driver 521 is a cylinder.

[0080] As shown in FIG7 , in one embodiment, the battery module end plate disassembly device further includes a deviation correction mechanism 300 , which is connected to the conveyor belt mechanism 200 and is used to correct the deviation and position the battery module.

[0081] The correction mechanism 300 includes two horizontal positioning drive members 310, which are respectively located on both sides of the conveyor belt mechanism 200 and connected to the conveyor belt mechanism 200. Each horizontal positioning drive member 310 includes a horizontal driving part 311 and a slider 312, and the slider 312 is connected to the power output end of the horizontal driving part 311.

[0082] It can be understood that when the battery module is conveyed to the position of the correction mechanism 300 via the conveyor belt mechanism 200, the conveyor belt mechanism 200 stops operating, and the correction mechanism 200 corrects and positions the battery module so that the clamping and moving mechanism 500 can better clamp the battery module. Furthermore, when the battery module is conveyed to the corresponding position by the conveyor belt mechanism 200, the conveyor belt mechanism 200 stops operating, and the horizontal driving parts 311 on both sides drive the sliders 312 to move against the battery module, so that the battery module is positioned at a preset position, thereby enabling the battery module to be better clamped by the clamping and moving mechanism 500. In this embodiment, the horizontal driving part 311 is a motor.

[0083] As shown in Figure 1, in one embodiment, the battery module end side plate disassembly device 10 also includes a photoelectric sensing switch component 700, which is arranged adjacent to the correction mechanism 300, and the photoelectric sensing switch component 700 is electrically connected to the conveyor belt mechanism 200, so that when the photoelectric sensing switch component 700 senses the battery module, the conveyor belt mechanism 200 stops conveying.

[0084] It can be understood that the photoelectric sensing switch component 700 is arranged on the side of the correction mechanism 300 adjacent to the rotating downward pressing stripping mechanism 400, that is, when the battery module is conveyed to the sensing position of the photoelectric sensing switch component 700 by the conveyor belt mechanism 200, the photoelectric sensing switch component 700 releases a signal to stop the conveyor belt mechanism 200. At this time, the battery module is just conveyed into the working range of the correction mechanism 300, so that the battery module can be positioned by the correction mechanism 300.

[0085] The present application also provides a method for disassembling the end and side panels of a battery module, wherein the end and side panels of the battery module are disassembled using the power battery module disassembly device described in any of the above embodiments; the disassembly method comprises:

[0086] S100: Pre-process the battery module to cut the welded area between the end plate and the side plate of the battery module. It is understood that the end plate and the side plate are still bonded together when the end plate and the side plate are cut by the cutting device. The end plate and the side plate are then disassembled and separated by the battery module end plate and side plate disassembly device 10.

[0087] S200 , the battery module to be disassembled is transported to the rotating platform assembly 430 by the transport mechanism 10 a .

[0088] S300 , pressing down and fixing the battery module by the pressing assembly 410 , so that the battery module is pressed down and fixed when the rotating pressing and peeling mechanism is working.

[0089] S400: The active end of the rotating plug assembly 420 is inserted into the through-hole of the battery module and moves horizontally to initially separate the end plate and side plate of the battery module. It will be understood that when the battery module is pressed downward and fixed, the second horizontal driving member 422 drives the plug assembly 425 to move horizontally, generating a tearing force between the end plate and the side plate, thereby initially separating the end plate and the side plate.

[0090] S500: The end plate and the side plate of the battery module are completely separated by rotating the rotating plug assembly 420. It can be understood that the rotation drive device 424 drives the plug 425 to rotate, thereby completely separating the end plate and the side plate of the battery module.

[0091] S600 , removing the separated end plates and side plates of the battery module from the rotating platform assembly 430 .

[0092] In one embodiment, the specific steps of conveying the battery module to be disassembled to the rotating pressing and peeling mechanism 400 by the conveying mechanism 10a include:

[0093] First, the battery module is placed on the conveyor mechanism 200. When the battery module is conveyed to the photoelectric sensor switch 700, the photoelectric sensor switch 700 outputs a sensing signal, and the conveyor mechanism 200 stops operating according to the sensing signal. Then, the correction mechanism 300 positions the battery module. At this time, the two horizontal positioning drive members 310 drive the slider 312 to abut against the battery module through the horizontal drive part 311, so that the battery module moves to the preset position. After the positioning is completed, the fourth horizontal drive member 530 of the clamping and moving mechanism 500 drives the moving frame 510 to move above the battery module. At this time, The fourth vertical drive member 540 drives the clamping assembly 520 to move downward. When the clamping assembly moves downward to a predetermined position, the clamping drive member 521 drives the two clamping plates 522 to move closer to each other to clamp the battery module; after clamping is completed, the fourth horizontal drive member 530 continues to drive the movable frame to move until the movable frame 510 moves to above the rotating platform 431. At this time, the clamping drive member 521 drives the two to move away from each other to release the battery module, so that the battery module is placed on the rotating platform 431; finally, driven by the fourth horizontal drive member 530 and the fourth vertical drive member 540, the movable frame 510 is reset.

[0094] In one embodiment, before the battery module is pressed down and fixed by the rotating downward pressing peeling mechanism 400, the disassembly method further includes: peeling and positioning the battery module. In this embodiment, the steps of peeling and positioning the battery module are as follows: first, the battery module is placed on the rotating platform 431 by the clamping and moving mechanism 500; after the battery module is located on the rotating platform 431, each positioning drive assembly 610 is driven by the corresponding third vertical drive member 612 to lift and lower it, so that each positioning drive assembly 610 is on the same horizontal line with the battery module; after each positioning drive assembly 610 is on the same horizontal line with the battery module, the positioning push block 613 of each positioning drive assembly 610 is on the corresponding Driven by the third horizontal driving member 611, it moves until it abuts against the battery module, so that each positioning slider 613 jointly pushes the battery module and positions it at the preset position, so that the connector 425 in the subsequent process can be reliably plugged into the through hole of the battery module; after the positioning is completed, each positioning driving assembly 610 is reset through the driving action of each third horizontal driving member 611 and the corresponding third vertical driving member 612 to carry out the moving and positioning operation of the next battery module, so that each battery module can be moved and positioned at the preset position.

[0095] Compared with the prior art, the present disclosure has at least the following advantages:

[0096] The battery module end and side panel disassembly device described above places the battery module to be disassembled on a conveying mechanism, which then transfers the battery module to a rotating platform assembly. The pressing assembly then presses down on the battery module, and after the pressing is complete, the active end of the rotating plug assembly plugs into the through-hole of the battery module. After the plugging is complete, the rotating plug assembly rotates until the end and side panels of the battery module are completely separated. The operating procedures of the device described above allow the end and side panels of the battery module to be completely separated, i.e., a fully streamlined operation without manual intervention, thereby avoiding safety issues during manual disassembly and improving disassembly efficiency.
