Description

[0001] The present application relates to the technical field of battery disassembly, and in particular to a lithium battery pack disassembly device. Background Art

[0002] As the use of electric energy equipment becomes more and more popular, the number of lithium batteries, as high-quality energy storage units, is increasing year by year. However, due to the limitation of lithium battery service life, the amount of scrapped lithium batteries is also increasing year by year. Therefore, the recycling, disassembly and reuse of waste lithium batteries is of great significance.

[0015] Compared with the prior art, the advantages of this application are:

[0016] (1) The present application divides the top of the operating table into four operating areas arranged around the auxiliary disassembly and cutting mechanism, and connects the electric slide rail between the center positions of two adjacent operating areas, cooperates with the grabbing table to grab the battery pack, and realizes the U-shaped conveyance of the battery pack. During the movement of the battery pack, the high-speed rotation of the saw blade is used to cut and cut off the buckles at the seams of the plastic shell of the battery pack. Compared with the prior art of disassembling the battery by prying the buckles, it can effectively avoid abnormal squeezing of the battery cells in the plastic shell of the battery pack, which is beneficial to improving the safety and efficiency of the battery pack disassembly process.

[0017] (2) By evenly distributing a large number of balls in the four operating areas, the battery pack can be lifted during its movement. At the same time, the rolling of the balls can effectively reduce the resistance encountered by the battery pack during its translation, which is conducive to ensuring the smoothness and stability of the battery pack during its movement.

[0018] (3) The supporting seat is rotatably connected to the U-shaped frame through the first rotating shaft, so that the auxiliary disassembly and cutting mechanism can not only adjust the direction of the saw blade by rotating the main shaft, but also adjust the inclination angle of the saw blade acting on the seam of the battery pack plastic shell by rotating the supporting seat. By cutting the buckle at the seam of the battery pack plastic shell at an inclined angle, the saw blade can be further prevented from cutting into the interior of the battery pack plastic shell, which is conducive to further improving the safety of the device when disassembling the battery pack.

[0019] (4) By providing two power switching mechanisms, the rotational power of the servo motor drive shaft can be transmitted to the main shaft, the first rotating shaft and the second rotating shaft respectively, so that only a single servo motor can be used to adjust the direction of the saw blade, the deflection angle of the saw blade, and the high-speed rotation of the saw blade. The operation is flexible and the usage of the servo motor can be effectively reduced. It is not only beneficial to reduce the manufacturing cost of the device, but also can effectively reduce the energy consumption of the device during actual use, which is conducive to achieving green and low-energy production.

[0020] (5) By providing a first electric push rod, the movement of the telescopic end of the first electric push rod can be used to control the connecting plate to drive the main shaft to move up and down, thereby realizing the adjustment of the upper and lower heights of the saw blade, so that the device can be adapted to different types of battery packs to cut and separate the buckles at the seams of the plastic shells, thereby improving the flexibility and applicability of the device to a certain extent.

[0021] (6) When the main shaft and the first rotating shaft are driven to rotate, the self-locking property of the worm and the worm wheel in the power switching mechanism when they are meshed can ensure the unidirectional power transmission, so that the main shaft and the bearing seat cannot rotate autonomously when the servo motor is not started, which is beneficial to ensure that the positions of the main shaft and the bearing seat are automatically fixed after rotation and adjustment, thereby ensuring the stability of the device during actual use.

[0022] (7) By fixing a dust extraction box with dust extraction holes around the cylindrical surface at the axial positions on both sides of the saw blade, and cooperating with the first connecting tube and the second connecting tube, the dust generated by cutting can be extracted during the cutting process, and the dust extraction operation can be directly applied to the cutting position, making the dust extraction more efficient and direct, avoiding the random scattering of dust during cutting during the disassembly of the battery pack, which is beneficial to improving the environmental safety and dust extraction efficiency during the use of the device. When using a vacuum cleaner to suck air from the dust extraction box, the strong airflow sucked by the vacuum cleaner can also be applied to the suction cup on the grabbing table. With the help of the negative pressure adsorption formed by the airflow suction, the connection between the bottom of the battery pack and the grabbing table is realized, and the grabbing of the battery pack by the grabbing table is completed. The grabbing connection of the battery pack by the grabbing table is completed by using airflow suction for outward adsorption, which can avoid squeezing of the battery pack during the grabbing process, which is beneficial to further ensure the safety of movement during the disassembly of the battery pack.

DETAILED DESCRIPTION

[0037] The embodiments will be combined with the drawings in the specification to clearly and completely describe the technical solution of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present application.

[0038] Embodiment 1:

[0039] The present invention provides a lithium battery pack disassembly device, please refer to Figure 1 - Fig.12, including an operating table 1, the top of the operating table 1 is equally divided into four operating areas 101, an electric slide rail 102 fixedly embedded in the top of the operating area 101 is connected between the center positions of two adjacent operating areas 101, a grabbing table 103 is fixedly installed on the moving end of the electric slide rail 102, an auxiliary disassembly and cutting mechanism is installed at the top center position of the operating table 1, the auxiliary disassembly and cutting mechanism includes a main shaft 2 that rotates vertically at the top center position of the operating table 1, and a U-shaped frame 201 is fixedly installed on the top of the main shaft 2, a bearing seat 202 is installed on the upper part of the U-shaped frame 201, and a vertically arranged second rotating shaft 204 is rotatably installed in the bearing seat 202, a saw blade 205 is coaxially fixed on the second rotating shaft 204, and a servo motor 206 is fixedly installed at the bottom of the operating table 1.

[0040] When the device is used, the staff places the battery pack to be disassembled on the top of the operating table 1, so that the operating table 1 is within the range of one of the operating areas 101, and adjusts the position of the battery pack so that the seam on the battery pack shell is close to the auxiliary disassembly and cutting mechanism, and the seam is aligned with the saw blade 205. Taking the left rear as the initial placement area of ​​the battery pack as an example, when the staff places the battery pack in this area and the front seam of the battery pack plastic shell is aligned with the saw blade 205, the staff controls the rear electric slide rail 102 to move The grabbing table 103 on the end is connected with the battery pack to grab the battery pack, and then the rear electric slide rail 102 moves rightward to drive the battery pack to move to the right. During the movement, the saw blade 205 is driven by the servo motor 206 to rotate at a high speed to cut the buckle at the front seam of the plastic shell of the battery pack. When the battery pack moves horizontally from the left rear to the right rear, the buckle at the front seam of the plastic shell of the battery pack is cut and broken. Then, by driving the servo motor 206, the main shaft 2 is controlled to drive the U-shaped frame 201 to rotate The battery pack is then transported from the right rear side to the right front side, and the buckle at the left side joint of the battery pack plastic shell is cut during the transportation process. Referring to the above operation, the battery pack is subsequently transported from the front and left side electric slide rails 102. By feeding and adjusting the position of the blade of the saw blade 205, the cutting of the buckles at the seams around the plastic shell of the battery pack is gradually completed. Afterwards, the staff can smoothly separate the main body of the plastic shell of the battery pack from the upper buckle plate. When using the saw blade 205 to cut the buckles at the seams of the plastic shell, the cutting depth of the saw blade 205 can be stably controlled. Compared with the prior art of prying the buckles to disassemble the battery, the abnormal squeezing of the battery cells in the plastic shell of the battery pack can be effectively avoided, which is beneficial to improving the safety of the battery pack disassembly process.

[0041] See also Figure 6 and Figure 8 The top of the operating table 1 is rollingly installed with a large number of balls 104 evenly distributed in multiple operating areas 101, and the top of the grabbing table 103 is flush with the top of the balls 104. When the device is in use, the large number of balls 104 are evenly distributed in the four operating areas 101, which can lift the battery pack during its movement. At the same time, with the help of the rolling of the balls 104, the resistance encountered by the battery pack during its translation can be effectively reduced, which is conducive to ensuring the smoothness and stability of the battery pack during its movement.

[0042] See also Figure 4 , Figure 7 and Fig.10 , a first rotating shaft 203 rotatably connected to the U-shaped frame 201 is coaxially fixed at both ends of the bearing seat 202, a shaft cylinder 3 is movably sleeved on the first rotating shaft 203, and a first bevel gear 301 is fixedly installed at the end of the shaft cylinder 3, a second bevel gear 302 meshing with the first bevel gear 301 is rotatably installed on the bearing seat 202, and the second bevel gear 302 is transmission-connected to the second rotating shaft 204, a vertically arranged shaft rod 4 is rotatably installed in the main shaft 2, and a third bevel gear 401 is fixedly installed on the top of the shaft rod 4, a fourth bevel gear 402 meshing with the third bevel gear 401 is rotatably installed in the U-shaped frame 201, a first prism 403 is connected to the lower end of the shaft rod 4, and a second prism 404 is connected to the lower end of the main shaft 2, a power switching mechanism is arranged between the first rotating shaft 203, the shaft cylinder 3 and the fourth bevel gear 402, and a power switching mechanism is also arranged between the first prism 403, the second prism 404 and the servo motor 206.

[0043] When the device is in use, since the supporting seat 202 is rotatably connected to the U-shaped frame 201 through the first rotating shaft 203, the auxiliary cutting mechanism can not only adjust the direction of the blade of the saw blade 205 by rotating the main shaft 2, but also adjust the inclination angle of the blade of the saw blade 205 acting on the seam of the plastic shell of the battery pack by rotating the supporting seat 202. By cutting the buckle at the seam of the plastic shell of the battery pack at the inclination angle, the saw blade 205 can be further prevented from cutting into the inside of the plastic shell of the battery pack, which is beneficial to further improve the safety of the device when disassembling the battery pack. The output direction of the drive shaft of the servo motor 206 can be adjusted by adjusting the power switching mechanism. When controlling the rotation of the main shaft 2, the rotational power provided by the drive shaft of the servo motor 206 is adjusted by the power switching mechanism between the first prism 403, the second prism 404 and the servo motor 206 and output to the second prism 404, driving the second prism 404 to rotate and then drive the main shaft 2 sleeved thereon to rotate, thereby completing the power transmission for the rotation of the main shaft 2.

[0044] When controlling the rotation of the support seat 202, the rotational power provided by the driving shaft of the servo motor 206 is first adjusted through the power switching mechanism between the first prism 403, the second prism 404 and the servo motor 206 and then output to the first prism 403. Subsequently, the first prism 403 drives the shaft rod 4 connected to its upper end to rotate during its rotation. With the help of the meshing of the third bevel tooth 401 and the fourth bevel tooth 402, and the adjustment of the power switching mechanism arranged between the first rotating shaft 203, the shaft cylinder 3 and the fourth bevel tooth 402, the rotational power is output to the first rotating shaft 203, thereby realizing the control and adjustment of the deflection angle of the support seat 202.

[0045] When the device drives the saw blade 205 to rotate at high speed, the rotational power provided by the servo motor 206 driving shaft is first transmitted to the shaft rod 4, and then output to the shaft cylinder 3 through the adjustment of the power switching mechanism set between the first rotating shaft 203, the shaft cylinder 3 and the fourth bevel tooth 402. Subsequently, with the help of the meshing of the first bevel tooth 301 and the second bevel tooth 302, and the transmission connection between the second bevel tooth 302 and the second rotating shaft 204, the rotational power is output to the saw blade 205, driving the saw blade 205 to rotate at high speed, so as to perform efficient and stable cutting operations on the buckles at the seams of the plastic shell of the battery pack.

[0046] During the use of the device, the rotational power of the servo motor 206 drive shaft is transmitted to the main shaft 2, the first rotating shaft 203 and the second rotating shaft 204 respectively through two power switching mechanisms, so that only a single servo motor 206 is used to provide power for adjusting the blade direction of the saw blade 205, the deflection angle of the saw blade 205, and the high-speed rotation of the saw blade 205. The operation is flexible and the usage of the servo motor 206 can be effectively reduced, which is not only conducive to reducing the manufacturing cost of the device, but also effectively reduces the energy consumption of the device during actual use, which is conducive to achieving green and low-energy production.

[0047] See also Figure 4 and Figure 7 The first prism 403 is slidably inserted into the shaft 4, and the outer size of the first prism 403 is adapted to the inner size of the shaft 4, the second prism 404 is slidably inserted into the main shaft 2, and the outer size of the second prism 404 is adapted to the inner size of the main shaft 2, and a vertically arranged first electric push rod 405 is fixedly installed at the bottom of the operating table 1, and a connecting plate 406 is rotatably sleeved on the outer side of the lower end of the main shaft 2, and the connecting plate 406 is fixedly connected to the telescopic end of the first electric push rod 405. When the device is in use, by providing the first electric push rod 405, the movement of the telescopic end of the first electric push rod 405 can be used to control the connecting plate 406 to drive the main shaft 2 to move up and down, thereby realizing the adjustment of the upper and lower heights of the saw blade 205, so that the device can be adapted to different types of battery packs to cut and separate the buckles at the seams of the plastic shells, which to a certain extent improves the flexibility and applicability of the device.

[0048] See also Fig. 9 , Fig.10 and Fig.12 The power switching mechanism includes a first gear 5 fixedly mounted at the ends of the shaft cylinder 3 and the first prism 403, and a worm wheel 501 fixedly mounted at the ends of the first rotating shaft 203 and the second prism 404. A spline shaft 502 arranged parallel to the first gear 5 and the worm wheel 501 is rotatably mounted on the outer sides thereof. A second gear 503 meshing with the first gear 5 is arranged between the first gear 5 and the spline shaft 502. A third gear 504 drivingly connected to the worm wheel 501 is arranged between the worm wheel 501 and the spline shaft 502. A fourth gear 505 is slidingly sleeved on the outer side of the spline shaft 502. The inner size of the fourth gear 505 matches the outer size of the spline shaft 502. The outer side is rotatably connected to a gear rack 506, and a second electric push rod 507 arranged parallel to the spline shaft 502 is installed on the outer side, and the telescopic end of the second electric push rod 507 is fixedly connected to the gear rack 506. The spline shaft 502 in the power switching mechanism of the first rotating shaft 203 and the shaft cylinder 3 is transmission-connected with the fourth bevel gear 402, and the spline shaft 502 in the power switching mechanism of the first prism 403 and the second prism 404 is fixedly connected with the driving shaft of the servo motor 206. A worm 508 is meshed on the outer side of the worm wheel 501, and a fifth bevel gear 509 is coaxially fixed at the end of the worm 508, and a sixth bevel gear 510 meshing with the fifth bevel gear 509 is coaxially fixed on the third gear 504.

[0049] When the device is in use, after the spline shaft 502 is driven to rotate, it will drive the fourth gear 505 slidably sleeved thereon to rotate synchronously, and then the gear frame 506 is controlled to move along the spline shaft 502 by the second electric push rod 507, so that the position of the fourth gear 505 on the spline shaft 502 can be adjusted to control whether the fourth gear 505 is meshed with the second gear 503 or the third gear 504. At the same time, the fourth gear 505 will only mesh with one of the second gear 503 and the third gear 504. When the fourth gear 505 is meshed with the second gear 503, with the help of the second gear 503 and the third gear 504, the fourth gear 505 can be meshed with the second gear 503. The meshing of a gear 5 can transmit the rotational power to the first gear 5, thereby driving the first prism 403 or the shaft cylinder 3 to rotate, and when the fourth gear 505 is meshed with the third gear 504, the third gear 504 is driven to rotate, which will drive the sixth bevel tooth 510 to rotate, and then with the help of the meshing of the sixth bevel tooth 510 and the fifth bevel tooth 509, the rotational power is transmitted to the worm 508, and with the help of the meshing of the worm 508 and the worm wheel 501, the rotational power is transmitted to the first gear 5, thereby driving the second prism 404 or the first rotating shaft 203 to rotate, and the two power switching mechanisms are used flexibly.

[0050] When the main shaft 2 and the first rotating shaft 203 are driven to rotate, the self-locking property of the worm 508 and the worm wheel 501 in the power switching mechanism when they are meshed can ensure the unidirectional power transmission, so that the main shaft 2 and the supporting seat 202 cannot rotate autonomously when the servo motor 206 is not started, which is beneficial to ensure that the positions of the main shaft 2 and the supporting seat 202 are automatically fixed after rotation and adjustment, thereby ensuring the stability of the device during actual use.

[0051] See also Figure 1 and Figure 4 A suction cup is provided on the top of the grabbing platform 103, and dust extraction boxes 6 are fixedly installed at the axial positions on both sides of the first rotating shaft 203, and dust extraction holes are evenly arranged on the cylindrical surface of the dust extraction box 6. The suction cup and the dust extraction box 6 are connected to an external dust extractor together, and the second rotating shaft 204 is connected to the dust extraction box 6. A first connecting pipe 601 that is rotatably connected to the second rotating shaft 204 is fixedly installed on the bearing seat 202, and the other end of the first connecting pipe 601 is connected to the first rotating shaft 203. A second connecting pipe 602 that is rotatably connected to the first rotating shaft 203 is fixedly installed on the U-shaped frame 201, and the other end of the second connecting pipe 602 is rotatably connected to the top of the shaft rod 4. The center positions of the shaft rod 4 and the first prism 403 are connected up and down. When the device is used, when the saw blade 205 is used to cut the buckle at the seam of the plastic shell of the battery pack, after the external air pump is powered on and started, it will pass through the first prism 403 and the center position of the shaft rod 4. The passage that runs through the upper and lower parts, as well as the connection between the second connecting pipe 602 and the first connecting pipe 601, acts on the dust extraction box 6, and the dust generated by cutting is extracted through the dust extraction holes arranged around the cylindrical surface of the dust extraction box 6. The dust extraction operation directly acts on the cutting position, making the dust extraction more efficient and direct, and avoiding the random scattering of dust during cutting during the disassembly of the battery pack, which is beneficial to improving the environmental safety and dust extraction efficiency during the use of the device. The pipe extending from the dust extraction device is rotatably connected to the bottom end of the first prism 403. When dust extraction is performed, with the help of the rotational connection between the first connecting pipe 601 and the second rotating shaft 204, the rotational connection between the second connecting pipe 602 and the first rotating shaft 203 and the shaft rod 4, and the telescopic connection between the shaft rod 4 and the first prism 403, the rotation of the main shaft 2, the bearing seat 202 and the saw blade 205 will not affect the suction of the airflow in the dust extraction box 6, which is beneficial to ensuring the operational stability of the device.

[0052] When using a vacuum cleaner to suck air from the dust box 6, the strong airflow in the vacuum cleaner can also act on the suction cup on the grabbing table 103, and with the help of negative pressure adsorption formed by the airflow suction, the connection between the bottom of the battery pack and the grabbing table 103 is achieved, and the grabbing of the battery pack by the grabbing table 103 is completed. The use of airflow suction for outward adsorption completes the grabbing and connection of the battery pack by the grabbing table 103, which can avoid squeezing the battery pack during the grabbing process, and is beneficial to further ensure the safety of movement during the disassembly of the battery pack.

[0053] The above are only the best implementation methods adopted by this application in combination with current actual needs, but the protection scope of this application is not limited to this.
