[0034] The following describes some embodiments of the present invention in detail with reference to the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0035] Please refer to Figures 1 to 4The present invention provides a battery disassembly and recycling device for disassembling and recycling lithium batteries. The device includes a cell packaging film removal device 100 that quickly removes the packaging film 310, achieving a high degree of automation and efficiency while avoiding damage to the internal structure of the cell 300.

[0036] It should be noted that the battery disassembly and recycling equipment includes a cell packaging film removal device 100 and a rewinding and disassembling device (not shown). The cell packaging film removal device 100 is connected to the rewinding and disassembling device; the cell packaging film removal device 100 is used to remove the packaging film 310 on the surface of the battery cell 300, facilitating the subsequent rewinding and disassembly of the battery cell 300; the rewinding and disassembling device is used to rewind the battery cell 300 to restore the wound battery cell 300 to a strip shape, facilitating the lossless separation of the positive and negative electrodes of the battery cell 300, reducing environmental pollution, and improving disassembly and recycling efficiency.

[0037] Specifically, the battery cell 300 includes a top cover 320, a plastic part 330, and a winding core 340. One side of the plastic part 330 is connected to the top cover 320, and the other side is connected to the winding core 340 to secure the overall structure of the battery cell 300. The cross-sectional area of ​​the top cover 320 is larger than that of the plastic part 330, and the cross-sectional area of ​​the plastic part 330 is equal to that of the winding core 340. A packaging film 310 is wrapped around the plastic part 330 and winding core 340 to further secure the overall structure of the battery cell 300. Therefore, in the process of removing the packaging film 310 using the battery cell packaging film removal device 100, the packaging film 310 is first cut along the connection position between the plastic part 330 and the core 340 to divide the packaging film 310 into two parts, the upper part of the packaging film 310 is covered on the outside of the plastic part 330, the area of ​​this part of the packaging film 310 is smaller, and it will not affect the subsequent rewinding and disassembly of the core 340, and does not need to be removed. The lower part of the packaging film 310 is covered on the outside of the core 340; then the lower part of the packaging film 310 is adsorbed and removed to complete the removal of the packaging film 310. After the packaging film 310 is removed, the rewinding and disassembly device can be used to rewind and disassemble the core 340, thereby realizing the disassembly and recycling of the battery cell 300.

[0038] The battery cell packaging film removal device 100 includes a base 110, a rotating mechanism 120, a rotating platform 130, a robot 140, a laser emitter 150, a camera mechanism 160, an air pump 170, a telescoping mechanism 180, a first suction cup 190, a clamping mechanism 200, a first belt drive mechanism 210, a second belt drive mechanism 220, and a second suction cup 230. The rotating mechanism 120 is mounted on the base 110 and connected to the rotating platform 130. The rotating platform 130 is used to place the battery cell 300, and the rotating mechanism 120 drives the battery cell 300 to rotate via the rotating platform 130. The manipulator 140 is installed on the base 110, and the laser emitter 150 is installed at the free end of the manipulator 140. The laser emitter 150 is used to laser cut the packaging film 310 on the surface of the battery cell 300 to cut off the packaging film 310, so as to facilitate the subsequent adsorption and removal of the packaging film 310. It has a high degree of automation and high removal efficiency, and can avoid damage to the internal structure of the battery cell 300.

[0039] It should be noted that the cross-sections of the top cover 320, plastic part 330, and winding core 340 are all rectangular, and the packaging film 310 is a hollow rectangular body. To separate the packaging film 310 into an upper and lower portion, the four sides of the packaging film 310 need to be laser cut separately. In this embodiment, when the battery cell packaging film removal device 100 cuts the packaging film 310, the laser emitter 150 is first activated and the robot 140 drives the laser emitter 150 to move to laser cut one side of the packaging film 310. After the laser emitter 150 cuts one side of the packaging film 310, the laser emitter 150 pauses, and the rotating mechanism 120 drives the battery cell 300 90 degrees via the rotating table 130. The robot 140 then drives the laser emitter 150 to cut the adjacent side of the packaging film 310. This process is repeated until all four sides of the packaging film 310 are cut, the laser cutting operation is completed, and the packaging film 310 is separated into an upper and lower portion.

[0040] In this embodiment, the laser emitter 150 is controlled to sequentially perform laser cutting on the four sides of the battery cell 300 by means of the rotating mechanism 120 driving the rotating table 130 to rotate and the manipulator 140 driving the laser emitter 150 to move. However, this is not limited to this. In other embodiments, the rotating mechanism 120 may remain stationary, and the manipulator 140 may drive the laser emitter 150 to rotate one circle around the battery cell to control the laser emitter 150 to sequentially perform laser cutting on the four sides of the battery cell 300. This can also achieve a cutting effect, dividing the packaging film 310 into two parts, upper and lower parts.

[0041] Furthermore, the position where the laser emitter 150 emits the laser corresponds to the connection position of the plastic part 330 and the winding core 340 in the battery cell 300, that is, the cutting position of the packaging film 310 is located between the plastic part 330 and the winding core 340. The laser emitter 150 cuts the packaging film 310 here, which can avoid the laser emitter 150 from causing damage to the internal structure of the battery cell 300 as much as possible, thereby facilitating the lossless separation of the positive and negative poles of the battery cell 300.

[0042] It should be noted that the melting point range of the packaging film 310 is 160 degrees Celsius to 180 degrees Celsius, so the laser emitter 150 uses a fiber laser with an operating power of 30 watts to 50 watts to ensure that the laser emitted by the laser emitter 150 can quickly and effectively cut off the packaging film 310 while preventing damage to the internal structure of the battery cell 300.

[0043] Manipulator 140 includes a first driver 141, a sliding frame 142, a second driver 143, a lifting frame 144, a third driver 145, and a mounting frame 146. First driver 141 is mounted on base 110 and connected to sliding frame 142. First driver 141 is used to drive sliding frame 142 to move in a first direction. Second driver 143 is mounted on sliding frame 142 and connected to lifting frame 144. Second driver 143 is used to drive lifting frame 144 up and down in a second direction. Third driver 145 is mounted on lifting frame 144 and connected to mounting frame 146. Laser emitter 150 is mounted on mounting frame 146. Third driver 145 is used to drive laser emitter 150 in a third direction via mounting frame 146.

[0044] In this embodiment, the first driving member 141 can drive the laser emitter 150 to move in the first direction through the sliding frame 142, the second driving member 143, the lifting frame 144, the third driving member 145 and the mounting frame 146, so as to realize the displacement function of the laser emitter 150 in the first direction; the second driving member 143 can drive the laser emitter 150 to rise and fall in the second direction through the lifting frame 144, the third driving member 145 and the mounting frame 146, so as to realize the displacement function of the laser emitter 150 in the second direction; the third driving member 145 can drive the laser emitter 150 to move in the third direction through the mounting frame 146, so as to realize the displacement function of the laser emitter 150 in the third direction; the first direction, the second direction and the third direction are perpendicular to each other, so that the laser emitter 150 can be moved to various positions in the three-dimensional coordinate system, thereby ensuring the accuracy of the laser emitter 150 in cutting the packaging film 310.

[0045] Furthermore, the camera mechanism 160 is installed on the mounting frame 146 and is electrically connected to the first driving member 141, the second driving member 143 and the third driving member 145 at the same time. The camera mechanism 160 is used to capture image information of the battery cell 300 and control the first driving member 141, the second driving member 143 and the third driving member 145 to adjust the position of the laser emitter 150 according to the image information to ensure that the laser emitter 150 can laser cut the packaging film 310 along the position between the plastic part 330 and the core 340, with a high degree of automation.

[0046] Please refer to Figure 5 and Figure 6 The rotating table 130 includes a table body 131, a first stop block 132, a second stop block 133, a third stop block 134, and a fourth stop block 135. The first stop block 132, the second stop block 133, the third stop block 134, and the fourth stop block 135 are connected end to end and are all connected to the table body 131. The first stop block 132, the second stop block 133, the third stop block 134, and the fourth stop block 135 together form a limiting cavity 136. The battery cell 300 is disposed in the limiting cavity 136. The table body 131 is used to support the battery cell 300. The first stop block 132, the second stop block 133, the third stop block 134, and the fourth stop block 135 are used to limit the battery cell 300 to prevent the battery cell 300 from moving relative to the table body 131, thereby ensuring the reliability of cutting the packaging film 310.

[0047] Specifically, the table body 131 is provided with an internal cavity 137 and a through-hole 138 communicating with the internal cavity 137. An air pump 170 is in communication with the internal cavity 137, which in turn communicates with the retaining cavity 136 via the through-hole 138. The air pump 170 is used to draw air into the through-hole 138 and the internal cavity 137, thereby adsorbing the packaging film 310 at the bottom of the battery cell 300 onto the table body 131. This can further secure the position of the battery cell 300 before the packaging film 310 is cut, preventing the battery cell 300 from swinging and causing positional deviation as the rotating table 130 rotates. Furthermore, after the packaging film 310 is cut, the position of the packaging film 310 can be secured, facilitating its detachment and removal.

[0048] Please continue to refer to Figure 3Furthermore, the retractable mechanism 180 is mounted on the table body 131 and connected to the first suction cup 190. The first suction cup 190 is in communication with the air pump 170. The position of the first suction cup 190 corresponds to the position of the winding core 340. The retractable mechanism 180 is used to drive the first suction cup 190 close to the battery cell 300 so that the first suction cup 190 can absorb the packaging film 310 on the side of the battery cell 300, thereby adsorbing the packaging film 310 on the side of the battery cell 300 onto the first suction cup 190. Similarly, the first suction cup 190 can further fix the position of the battery cell 300 before the packaging film 310 is cut, preventing the battery cell 300 from swinging and causing positional deviation as the rotating table 130 rotates. The first suction cup 190 can also fix the position of the packaging film 310 after the packaging film 310 is cut, so as to facilitate the detachment and removal of the packaging film 310.

[0049] In this embodiment, there are two retractable mechanisms 180 and two first suction cups 190. Each retractable mechanism 180 is connected to a first suction cup 190. The two first suction cups 190 are positioned opposite each other on either side of the battery cell 300. The two retractable mechanisms 180 are used to synchronously move the two first suction cups 190 toward or away from each other to attract the packaging film 310 or to move the battery cell 300 out of position. The two first suction cups 190 work together to simultaneously attract the packaging film 310 on opposite sides of the battery cell 300, further improving the attraction effect.

[0050] It is noteworthy that both the first belt drive mechanism 210 and the second belt drive mechanism 220 are mounted on the base 110, with the rotating platform 130 disposed between the first and second belt drive mechanisms 210 and 220. The first belt drive mechanism 210 is used to feed the battery cells 300 from which the packaging film 310 has been retained, while the second belt drive mechanism 220 is used to discharge the battery cells 300 from which the packaging film 310 has been removed. The clamping mechanism 200 is mounted on the free end of the manipulator 140, that is, the clamping mechanism 200 is mounted on the mounting frame 146. The manipulator 140 is capable of driving the clamping mechanism 200 to move, and the clamping mechanism 200 is used to clamp or release the battery cells 300. Specifically, the robot 140 is used to send the battery cell 300 from the first belt transmission mechanism 210 to the rotating table 130 through the clamping mechanism 200 to realize the loading of the battery cell 300 and facilitate the removal of the packaging film 310 outside the battery cell 300; the robot 140 is also used to send the battery cell 300 from the rotating table 130 to the second belt transmission mechanism 220 through the clamping mechanism 200 to realize the unloading of the battery cell 300 and facilitate the delivery of the battery cell 300 after the packaging film 310 is removed to the next workstation.

[0051] Please refer to Figure 7The clamping mechanism 200 includes a first cylinder 201, a first clamping plate 202, a second cylinder 203, and a second clamping plate 204. The first cylinder 201 and the second cylinder 203 are both mounted on the manipulator 140 and are positioned on opposite sides of the battery cell 300. The first cylinder 201 is connected to the first clamping plate 202, and the second cylinder 203 is connected to the second clamping plate 204. The first cylinder 201 is used to move the first clamping plate 202 toward or away from the second cylinder 203, and the second cylinder 203 is used to move the second clamping plate 204 toward or away from the first cylinder 201. The first clamping plate 202 and the second clamping plate 204 are used to clamp the battery cell 300.

[0052] Specifically, the first cylinder 201 and the second cylinder 203 are both located above the battery cell 300. The first and second clamping plates 202 and 204 extend downward to clamp both sides of the battery cell 300. Because the cross-sectional area of ​​the top cover 320 of the battery cell 300 is larger than the cross-sectional areas of the plastic part 330 and the winding core 340, when the clamping mechanism 200 clamps the battery cell 300, the first and second clamping plates 202 and 204 only clamp the top cover 320 and do not come into contact with the plastic part 330 and the winding core 340. In this way, after the packaging film 310 is cut, the packaging film 310 is divided into two parts, the upper packaging film 310 is covered on the outside of the plastic part 330, and the lower packaging film 310 is covered on the outside of the winding core 340. At this time, the clamping mechanism 200 clamps the top cover 320, and the manipulator 140 drives the top cover 320 to rise through the clamping mechanism 200, while the lower packaging film 310 is adsorbed on the rotating table 130 and the first suction cup 190 and remains motionless, so as to pull the battery cell 300 out of the lower packaging film 310 and complete the removal of the lower packaging film 310, thereby realizing the removal function of the packaging film 310 of the battery cell 300.

[0053] Please continue to refer to Figure 1 In this embodiment, the second suction cup 230 is installed at the free end of the manipulator 140 and is connected to the air pump 170, that is, the second suction cup 230 is installed on the mounting frame 146. The second suction cup 230 is used to adsorb the top cover 320 of the battery cell 300 to assist the clamping mechanism 200 in fixing the position of the top cover 320, thereby fixing the position of the entire battery cell 300, so as to facilitate the function of pulling the battery cell 300 out of the lower part of the packaging film 310 when the manipulator 140 drives the clamping mechanism 200 and the second suction cup 230 to rise.

[0054] Specifically, when the robot 140 sends the battery cell 300 with the packaging film 310 removed to the second belt transmission mechanism 220 through the clamping mechanism 200 and the second suction cup 230, the clamping mechanism 200 is controlled to release the top cover 320, and the second suction cup 230 is controlled to no longer adsorb the top cover 320, so as to place the battery cell 300 with the packaging film 310 removed on the second belt transmission mechanism 220, and the second belt transmission mechanism 220 is used to send the battery cell 300 to the next workstation.

[0055] In this embodiment, there are two second suction cups 230, which are arranged side by side and are both installed on the mounting frame 146.

At this time, the packaging film 310 is divided into two parts, the upper and lower parts; then the top cover 320 of the battery cell 300 is clamped by the clamping mechanism 200, and the top cover 320 of the battery cell 300 is adsorbed by the second suction cup 230 to fix the position of the battery cell 300, and the top cover 320 is driven up by the manipulator 140 through the clamping mechanism 200 and the second suction cup 230 to extract the battery cell 300 from the lower packaging film 310; then the top cover 320 is pulled out of the lower packaging film 310 by the manipulator 140. The robot 140 uses the clamping mechanism 200 and the second suction cup 230 to deliver the battery cell 300 to the second belt drive mechanism 220. The clamping mechanism 200 is then controlled to release the top cover 320 of the battery cell 300, and the second suction cup 230 is controlled to stop suctioning the top cover 320. Finally, the second belt drive mechanism 220 is used to deliver the battery cell 300, with the packaging film 310 removed, to the next station. The lower portion of the packaging film 310 attached to the rotating table 130 and the first suction cup 190 is manually or mechanically removed, completing the removal of the packaging film 310. This process is repeated to remove the packaging film 310 from multiple battery cells 300, achieving high removal efficiency.
