[0046] The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0047] This embodiment relates to a battery pack disassembling device, which improves the disassembling efficiency by optimizing its own structure.

[0048] In terms of the overall structure, the battery pack disassembly device includes a frame 1, a moving part provided on the frame 1, and a disassembly part provided at the moving end of the moving part. The moving part can drive the disassembly part to slide relative to the frame 1 to adjust the position of the disassembly part on the frame 1. The disassembly part includes a first driving part 4 provided at the moving end, and a milling mechanism and an ejecting mechanism provided at the power output end of the first driving part 4. The milling mechanism is used to mill the housing of the battery pack, and the ejecting mechanism is used to eject the battery from the milled housing.

[0049] For the battery pack disassembly device described in this embodiment, by setting the moving part, it is beneficial to adjust the position of the plug-in part on the frame 1, and the housing of the battery pack is milled by the milling mechanism on the first driving part 4, and the battery is ejected by the ejecting mechanism. Compared with the traditional disassembly method, it not only helps to improve the disassembly efficiency of the battery pack, but also reduces the operation of personnel, thus facilitating the protection of personnel safety.

[0050] Based on the above overall introduction, an exemplary structure of the battery pack disassembly device described in this embodiment is as Figure 1 shown in. As a preferred implementation manner, the moving part can drive the disassembly part to move in the length direction and width direction of the frame 1, so as to adjust the position of the disassembly part on the frame 1. In this way, it is not only beneficial to mill the housing, but also convenient to eject the batteries at different positions.

[0051] In some implementation manners, as Figure 1 shown in, the moving part can adopt a gantry structure in the prior art, which is beneficial to flexibly adjust the position of the disassembly part and is easy to arrange. As a structural example, the gantry structure in this embodiment includes first slide rails 101 provided on two opposite sides of the frame 1 and extending along the first direction of the frame 1, a sliding seat 2 slidably provided on the two first slide rails 101, second slide rails 102 provided on two opposite sides of the sliding seat 2 and extending along the second direction of the frame 1, and a moving seat 100 slidably provided on the two second slide rails 102. The moving seat 100 is the moving end of the moving part. Among them, one of the first direction and the second direction is the length direction of the frame 1, and the other is the width direction of the frame 1.

[0052] The gantry structure in this embodiment further includes a first linear driving part for driving the sliding seat 2 to slide along the first slide rail 101, and a second linear driving part for driving the moving seat 100 to slide along the second slide rail 102. During specific implementation, the first linear driving part and the second linear driving part can receive control instructions to drive the sliding seat 2 and the moving seat 100 to slide, and then move the disassembly part on the moving seat 100 to the target position on the frame 1. The first linear driving part and the second linear driving part can adopt products such as a motor 14 that can output a linear driving force.

[0053] As Figures 2 to 5As shown in the figure, both the milling mechanism and the ejection mechanism are provided on the moving seat 100. First, the structure of the milling mechanism will be described below. The first driving part 4 includes an electric cylinder provided on the frame 1. The milling mechanism includes a milling spindle 1001 provided at the power output end of the electric cylinder and a milling cutter 10 provided on the milling spindle 1001. The electric cylinder has mature products and good driving effects. The setting of the milling spindle 1001 is also conducive to improving the milling efficiency of the housing. For different materials, the milling cutters 10 used for milling the upper housing and the lower housing can be made of different materials.

[0054] Specifically, as Figures 2 to 4 shown in the figure, an adjustment seat 5 is provided below the moving seat 100. The adjustment seat 5 is slidably provided on the moving seat 100 through a plurality of guide posts 201 passing through the moving seat 100. The tops of the plurality of guide posts 201 are connected to a top plate 202 located on the moving seat 100. The electric cylinder is provided on the moving seat 100, and the power output end of the electric cylinder is connected to the adjustment seat to drive the adjustment seat to slide up and down relative to the moving seat 100. Both the milling mechanism and the ejection mechanism are provided on the adjustment seat 5.

[0055] In detail, as Figure 3 and Figure 5 shown in the figure, the adjustment seat 5 includes a horizontal plate 501 at the top, a vertical plate 502 connected to one side of the horizontal plate 501, and a reinforcing plate 504 with a triangular outer contour connected between the horizontal plate 501 and the vertical plate 502. Among them, the milling mechanism is installed on the outer side of the vertical plate 502. An installation plate 3011 is also provided on the vertical plate 502 above the milling spindle 1001. A motor 14 is provided on the installation plate 3011. The power output end of the motor 14 and the top end of the milling spindle 1001 are connected by a synchronous belt drive to drive the milling spindle 1001 and the milling cutter 10 to rotate around their own axes.

[0056] In addition, as Figure 3 shown in the figure, a dust suction part 9 is provided at the power output end of the first driving part 4. The dust suction part 9 is arranged adjacent to the milling end of the milling mechanism. This is conducive to collecting the milling chips generated by milling and has good collection efficiency, thus helping to prevent the milling chips from affecting the surrounding environment. Specifically, the dust suction part 9 includes a dust suction hood provided on the vertical plate 502 and opening towards the milling cutter 10. The outlet of the dust suction hood is connected to an external negative pressure part through a pipeline to suck the area near the milling cutter 10, thereby collecting the milling chips. Of course, the number of dust suction hoods can also be increased according to the use requirements.

[0057] As a preferred embodiment, a second driving part 15 is provided at the power output end of the first driving part 4, and a detecting part 1101 is provided at the power output end of the second driving part 15. The second driving part 15 can drive the detecting part 1101 to move up and down, so that the detecting part 1101 can be switched between a use state and a non-use state, and there is a preset distance between the detecting end of the detecting part 1101 in the non-use state and the milling end of the milling mechanism. The detecting part 1101 is used to detect the distance between the detecting end of the detecting part 1101 in the use state and the housing of the battery pack.

[0058] The arrangement of the detecting part 1101 here is conducive to determining the displacement of the milling mechanism when milling the housing of the battery pack, thereby facilitating the improvement of the milling effect on the housing. At the same time, when the detecting part 1101 detects the housing, the milling cutter 10 does not contact the housing, and when the milling cutter 10 mills the housing, the detecting part 1101 will not interfere with the housing, thus ensuring the use effects of the detecting part 1101 and the milling cutter 10 respectively.

[0059] Specifically, as shown in Figure 5 A third slide rail 505 extending along the height direction of the frame 1 is provided inside the vertical plate 502, and a slider is slidably provided on the third slide rail 505. A detecting plate 11 extending downward is connected to the slider, and the detecting part 1101 is specifically arranged at the bottom end of the detecting plate 11. The second driving part 15 can be a cylinder arranged on the vertical plate 502, which is connected to the slider and is used to drive the slider to drive the detecting plate 11 and the detecting part 1101 thereon to slide up and down, so that the detecting part 1101 can be switched between the non-use state and the use state.

[0060] The detecting part 1101 in this embodiment can adopt a contact sensor in the prior art. Under the action of the second driving part 15, the detecting part 1101 is brought into contact with the housing, and the moving part drives the moving seat 100 to move along the circumferential direction of the housing, so that the distance between the milling cutter 10 and any point on the milling path of the housing can be obtained, and the measured distance value is sent to the control system. Since the surface of the housing here is uneven, using a contact displacement sensor to contact the housing and measure the distance is conducive to improving the measurement accuracy.

[0061] During the process of the moving part moving the moving seat 100 along the preset moving track, the electric cylinder strictly controls the feed amount in the height direction of the frame 1, and cooperates with the measurement feedback value of the detecting part 1101 to strictly ensure that the milling cutter 10 will not damage the pole column on the surface of the cylindrical battery during Z-direction milling. At the same time, during the milling process, the dust suction hood will collect the milling chips to ensure that the milling chips will not fly everywhere.

[0062] As a preferred embodiment, the ejection mechanism includes a third driving part 12 provided at the power output end of the first driving part 4, and an ejector rod 6 provided at the power output end of the third driving part 12. The third driving part 12 can drive the ejector rod 6 to move up and down, so that the ejector rod 6 can be switched between a contracted state and an extended state. A holding part is provided at the power output end of the first driving part 4, and the holding part is used to hold the ejector rod 6 in the extended state. The arrangement of the third driving part 12 and the ejector rod 6 in the ejection mechanism helps to ensure that the ejection of the battery by the ejection mechanism does not interfere with the milling of the housing by the milling mechanism, and the arrangement of the holding part helps to ensure the use stability of the ejector rod 6.

[0063] Specifically, referring to Figure 4 , Figure 6 and Figure 7 as shown, relative to the vertical plate 502, a vertical plate 503 is further provided at the bottom of the horizontal plate 501, and a reinforcing plate 504 connecting the two is also provided between the horizontal plate 501 and the vertical plate 503. The third driving part 12 is provided on the vertical plate 503. Preferably, the third driving part 12 adopts a cylinder, and a pilot solenoid valve 1201 is provided on the cylinder. By providing the pilot solenoid valve 1201, it is beneficial to ensure that the ejector rod 6 will not fall when the cylinder cuts off air and power, thus playing a role in safety protection.

[0064] The holding part in this embodiment includes a fourth driving part 8 provided at the power output end of the first driving part 4, and a limiting rod 1302 provided at the power output end of the fourth driving part 8. The limiting rod 1302 is driven by the fourth driving part 8 and can be inserted into the ejector rod 6 along the radial direction of the ejector rod 6. The structures of the fourth driving part 8 and the limiting rod 1302 are simple, convenient to arrange and implement, and have good limiting effects.

[0065] As Figure 4 and Figure 6 shown, the fourth driving part 8 is located on one side of the third driving part 12 and is also installed on the vertical plate 503. The fourth driving part 8 here can also adopt a cylinder. To improve the limiting effect of the limiting rod 1302, a limiting hole 602 penetrating the radial direction is provided at the top of the ejector rod 6. When the ejector rod 6 moves downward until the limiting rod 1302 and the limiting hole 602 correspond to each other one by one, the limiting rod 1302 can be inserted into the limiting hole 602, so that the ejector rod 6 cannot generate displacement along its own axial direction and has good ejection stability.

[0066] To further improve the usage stability of the ejector rod 6, in this embodiment, a first anti-rotation part is provided between the ejector rod 6 and the third driving part 12. The first anti-rotation part is used to limit the rotation of the ejector rod 6 relative to the third driving part 12, thereby ensuring the usage stability of the ejector rod 6. Specifically, the first anti-rotation part includes a first anti-rotation seat 7 provided on the third driving part 12 and a first anti-rotation block 701 provided on the first anti-rotation seat 7. The ejector rod 6 is slidably inserted into the first anti-rotation seat 7 and is provided with a first anti-rotation groove 601 extending along its length direction. One end of the first anti-rotation block 701 is inserted into the first anti-rotation groove 601.

[0067] Among them, the first anti-rotation seat 7 is arranged on the vertical plate 503. The first anti-rotation groove 601 extends along the axial direction of the ejector rod 6. The first anti-rotation blocks 701 are two spaced along the axial direction of the ejector rod 6 on the first anti-rotation seat 7, which is beneficial to ensuring the anti-rotation stability. In addition, rolling balls are provided at the ends of the first anti-rotation blocks 701 and are located in the first anti-rotation groove 601, which is beneficial to reducing the friction during the up and down movement of the ejector rod 6 and also makes the first anti-rotation part have better anti-rotation stability.

[0068] In this embodiment, a second anti-rotation part is provided between the limit rod 1302 and the fourth driving part 8. The second anti-rotation part is used to limit the rotation of the limit rod 1302 relative to the fourth driving part 8, thereby ensuring the usage stability of the limit rod 1302. As a preferred structural example, the second anti-rotation part includes a second anti-rotation seat 13 provided on the fourth driving part 8 and a second anti-rotation block 1301 provided on the second anti-rotation seat 13. The limit rod 1302 is slidably inserted into the second anti-rotation seat 13 and is provided with a second anti-rotation groove 1303 extending along its length direction. One end of the second anti-rotation block 1301 is inserted into the second anti-rotation groove 1303.

[0069] As shown in Figure 6 and Figure 7 The second anti-rotation seat 13 is arranged on the vertical plate 503, and the second anti-rotation groove 1303 extends along the axial direction of the limit rod 1302. The second anti-rotation blocks 1301 are two spaced along the axial direction of the limit rod 1302 on the second anti-rotation seat 13, which is beneficial to ensuring the anti-rotation stability. In addition, rolling balls are respectively provided at the ends of the second anti-rotation blocks 1301 and are located in the second anti-rotation groove 1303, which is beneficial to reducing the friction during the movement of the limit rod 1302 and makes the second anti-rotation part have better anti-rotation stability.

[0070] As a preferred implementation method, as shown in Figure 8As shown, the ejector rod 6 is cylindrical, and a laser emitter 603 is provided at the center of the free end of the ejector rod 6. In this way, the emitted laser can be used to determine whether the ejector rod 6 is concentric with the battery, so as to eliminate the positioning error during ejection. Specifically, when arranging, an installation groove can be provided at the bottom end of the ejector rod 6, and the laser emitter 603 is received in the installation groove. In this embodiment, the bottom end of the ejector rod 6 is preferably made of PEEK (Polyetheretherketone), and the bottom end of the ejector rod 6 can be made into a profiling structure according to the structure of the battery. Moreover, the material is insulated and has a relatively high hardness.

[0071] In addition, the battery pack disassembling device in this embodiment further includes a transfer part, and the transfer part is used to transfer the battery pack to the lower part of the disassembling part. As a preferred implementation manner, as Figure 1 shown, the transfer part includes a carrier vehicle 16 with wheels. By providing the transfer part, it is convenient to transfer the battery pack to the lower part of the disassembling part, so as to facilitate the milling mechanism to mill the housing of the battery pack. Moreover, the product of the carrier vehicle 16 is mature and the transfer effect is good.

[0072] The carrier vehicle 16 in this embodiment can adopt products in the prior art. For example, a plurality of wheels are provided at the bottom of the carrier vehicle 16, and a braking mechanism for locking the wheels is provided. A supporting plate for supporting the frame of the battery pack is provided at the top of the carrier vehicle 16, and the middle of the supporting plate is provided with a through hole to facilitate the ejection of each battery in the battery pack. In addition, a plurality of buckles are provided on the supporting plate along the circumferential direction of the supporting plate, and the buckles can be lapped on the battery pack frame, so as to fix the battery pack on the carrier vehicle 16. The buckles here have the advantage of facilitating the taking and placing of the battery pack. After milling the upper housing of the battery pack, manually remove the upper housing, then rotate the battery pack so that the lower housing is facing upwards, continue to mill the lower housing through the milling cutter 10, and at the same time disassemble the lower housing.

[0073] In addition, a positioning part is provided between the transfer part and the frame 1, and the positioning part is used to position the transfer part. Here, by providing the positioning part, it is beneficial to the position stability of the battery pack to be disassembled. In some implementation manners, as Figure 1 and Figure 9 shown, the positioning part includes two limiting seats 301 arranged oppositely. A channel for the carrier vehicle 16 to enter and exit is defined between the two limiting seats 301, and limiting plates 302 are detachably connected between the ends of the two limiting seats 301 respectively. The two limiting plates 302 and the two limiting seats 301 cooperate to define a limiting space for positioning the carrier vehicle 16, so as to ensure the position stability of the battery pack during the disassembly process.

[0074] To ensure the effect of the carrier vehicle 16 when entering and exiting the passage, mounting plates 3011 are respectively provided inside each limit seat 301, and a plurality of rollers 3012 are rotatably provided on each mounting plate 3011 at intervals along its own length direction. By the abutment of the rollers 3012 against the carrier vehicle 16, it is beneficial to reduce the frictional force of the carrier vehicle 16 during the transfer process, and the limiting effect of the limit seat 301 on the carrier vehicle 16 can also be ensured. In addition, a plurality of fixing plates 3013 are provided at intervals at the bottom of the limit seat 301, so that the positioning frame 3 is fixedly arranged relative to the frame 1. Of course, the positioning portion can also adopt other structural forms as long as it meets the positioning requirements for use.

[0075] When the battery pack disassembling device in this embodiment is in use, first, the battery pack is positioned on the carrier vehicle 16, then the carrier vehicle 16 is pushed to the target position on the frame 1, and then the carrier vehicle 16 is positioned on the frame 1 through the positioning portion. Then, the second driving portion 15 drives the detecting portion 1101 to slide downward until it abuts against the housing. At the same time, the moving portion drives the moving seat 100 to move along the circumferential direction of the battery pack housing, so as to obtain the distance between the milling cutter 10 and the upper housing on the milling path. Then, the first driving portion 4 drives the milling mechanism to move up and down, so that the milling cutter 10 displaces along the preset path and preset height to mill the upper housing (including the bus bar), and then the upper housing at the top of the battery pack is removed.

[0076] Then, repeat the above milling steps to mill the lower housing of the battery pack. Manually connect the heating system interface to the water inlet and outlet of the battery pack, and soften the glue between the batteries through hot water to facilitate the subsequent ejection of the batteries. Then, move the moving seat 100 to the target position and make it located at the top of the battery to be ejected. At the same time, determine the center of the cylindrical battery through the laser emitter 603, so that the ejector rod 6 is aligned with the pole column of the battery. At the same time, the limiting rod 1302 is inserted into the ejector rod 6 to limit the position of the ejector rod 6. Finally, the ejector rod 6 moves downward and ejects the corresponding battery.

[0077] Compared with the prior art in the disassembly solution that combines milling and jacks: the milling of the bus bar needs to be carried out manually by people, and when ejecting a single battery, it also requires manpower to use a jack and other tools to eject, and the chips cannot be effectively collected, etc. The battery pack disassembling device in this embodiment can effectively collect the chips, does not require manual intervention for the milling of the bus bar, and the battery ejection is also automatic, which is beneficial to improving the disassembly efficiency, and further beneficial to reducing manual operation and the safety of personnel.

[0078] In addition, compared with the disassembly solution in the prior art where a pneumatic mill and a hydraulic rod are combined, manual handling of the pneumatic mill by a person is required to mill the upper and lower shells, and the battery is ejected in the form of a hydraulic rod when the battery is ejected. The battery pack disassembly device of this embodiment mills the shell through the milling spindle 1001 cooperating with the milling cutter 10, and the battery is automatically ejected by the ejector rod 6 when the battery is ejected, thereby greatly facilitating the improvement of the disassembly efficiency, reducing the degree of personnel participation, and further facilitating the guarantee of personnel safety.

[0079] The foregoing are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
