[0033] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0034] Please refer to Figures 1 to 8 The embodiment of the utility model provides a wound battery cell disassembly device 100 for disassembling and recycling a wound battery cell 200. It can realize the automatic disassembly and recycling of the wound battery cell 200, effectively shorten the recycling cycle, improve the recycling efficiency, avoid the loss of battery materials, and improve the battery material recycling rate.

[0035] It should be noted that the wound battery cell disassembly device 100 is used in the recycling process of the wound battery cell 200. The wound battery cell 200 includes a sleeve 210, a core 220 and two end covers (not shown), wherein the two end covers are arranged at the two ends of the sleeve 210 opposite to each other and are welded to the sleeve 210. The core 220 is arranged in the sleeve 210. The sleeve 210 and the two end covers work together to shield and protect the core 220 and improve the integrity of the entire wound battery cell 200. Specifically, the core 220 is formed by overlapping and winding the positive electrode strip 221, the negative electrode strip 222 and the separator 223 to improve the energy density and power supply performance of the wound battery cell 200.

[0036] In this embodiment, the wound battery cell 200 is an aluminum shell battery cell, and the wound battery cell 200 is cylindrical. When the wound battery cell disassembly device 100 is used to recycle the wound battery cell 200, the sleeve 210 and the two end caps at both ends of the wound battery cell 200 are first cut off to make the two end caps fall off the sleeve 210. At this time, the core 220 remains in the sleeve 210, and the end caps no longer stop and limit the core 220; then the core 220 is extracted from the sleeve 210 to separate the core 220 from the sleeve 210; then the core 220 is unwound to obtain the positive electrode strip 221, the negative electrode strip 222 and the separator 223 respectively, and the disassembly of the wound battery cell 200 is completed. Afterwards, the user can process the positive electrode material strip 221 and the negative electrode material strip 222 respectively by physical kneading or chemical immersion to recover the positive and negative battery materials. In this process, since the positive electrode material strip 221 and the negative electrode material strip 222 are relatively intact, the loss of battery materials can be avoided and the battery material recovery rate can be improved.

[0037] The wound cell disassembly device 100 comprises a frame 110, a feeding roller 120, a feeding mechanism 130, a transfer mechanism 140, a cutting mechanism 150, a shelling mechanism 160 and an unwinding mechanism 170. The feeding roller 120, the feeding mechanism 130, the transfer mechanism 140, the cutting mechanism 150, the shelling mechanism 160 and the unwinding mechanism 170 are all installed on the frame 110, and the feeding mechanism 130, the cutting mechanism 150, the shelling mechanism 160 and the unwinding mechanism 170 are arranged at intervals and are arranged around the transfer mechanism 140. Specifically, the feeding mechanism 130 is arranged at the end of the feeding roller 120, the feeding roller 120 is used to feed the wound battery cell 200, and the feeding mechanism 130 is used to transport the wound battery cell 200 on the feeding roller 120 to the transfer mechanism 140 to realize the feeding function of the wound battery cell 200; the transfer mechanism 140 is used to send the wound battery cell 200 to the first preset position, and the cutting mechanism 150 is used to cut the wound battery cell 200 located at the first preset position to remove the end caps of the wound battery cell 200 and obtain the pre-processed battery cell 230 (including the winding core 220 and the sleeve 210), thereby eliminating the limiting effect of the end cap on the winding core 220. The transport mechanism 140 is used to realize the cutting function of the wound battery cell 200; the transport mechanism 140 is also used to send the pre-treated battery cell 230 to the shelling mechanism 160, and the shelling mechanism 160 is used to take out the core 220 in the pre-treated battery cell 230, and send the core 220 back to the transport mechanism 140 to separate the core 220 from the sleeve 210, thereby completing the core pulling and shelling function of the core 220; the transport mechanism 140 is also used to send the core 220 to the unwinding mechanism 170, and the unwinding mechanism 170 is used to disassemble the core 220 to separate the positive electrode material strip 221, the negative electrode material strip 222 and the separator 223 from each other, thereby realizing the unwinding and recycling function of the core 220. In this way, the loading mechanism 130 transports the wound battery cell 200 to the transfer mechanism 140, and through the transfer operation of the transfer mechanism 140, the wound battery cell 200 passes through the cutting mechanism 150, the shelling mechanism 160 and the unwinding mechanism 170 in sequence, and in this process, the cutting operation, the shelling operation and the unwinding operation are sequentially performed, thereby realizing the automated disassembly and recycling of the wound battery cell 200, effectively shortening the recycling cycle and improving the recycling efficiency. In addition, since the positive electrode material strip 221 and the negative electrode material strip 222 are led out by unwinding, the structure is relatively intact, so it can avoid causing loss of battery materials and improve the battery material recovery rate.

[0038] The feeding mechanism 130 includes a first manipulator 131, a first driving member 132, a rotating frame 133 and a first electric clamp 134. The first manipulator 131 is mounted on the frame 110, the first driving member 132 is mounted on the free end of the first manipulator 131 and is connected to the rotating frame 133, the first electric clamp 134 is mounted on the rotating frame 133, the first electric clamp 134 is used to clamp or release the wound battery cell 200, the first driving member 132 is used to drive the first electric clamp 134 to rotate through the rotating frame 133 to adjust the posture of the wound battery cell 200, so as to facilitate its delivery to the transfer mechanism 140, and the first manipulator 131 is used to drive the first electric clamp 134 to move through the first driving member 132 and the rotating frame 133, so as to realize flexible clamping and release of the wound battery cell 200.

[0039] Furthermore, the wound battery cell 200 is placed vertically on the feeding roller 120 and is fed forward by the feeding roller 120 . When the feeding roller 120 feeds the wound battery cell 200 to the loading position, the loading mechanism 130 feeds the wound battery cell 200 to deliver the wound battery cell 200 to the transfer mechanism 140 . During the loading process of the wound battery cell 200, first, the first manipulator 131 drives the first electric clamp 134 to move to the loading position through the first driving member 132 and the rotating frame 133; then, the vertically arranged wound battery cell 200 is clamped by the first electric clamp 134; then, the first manipulator 131 drives the first electric clamp 134 to move to the position corresponding to the transfer mechanism 140 through the first driving member 132 and the rotating frame 133. During this process, the first driving member 132 drives the rotating frame 133 to rotate 90 degrees, thereby driving the wound battery cell 200 to rotate 90 degrees through the first electric clamp 134, and then adjusting the posture of the wound battery cell 200 so that the wound battery cell 200 is arranged horizontally; then, the transfer mechanism 140 takes over the wound battery cell 200 from the first electric clamp 134, the first electric clamp 134 releases the wound battery cell 200, and the first manipulator 131 drives the first electric clamp 134 to reset through the first driving member 132 and the rotating frame 133.

[0040] The first manipulator 131 includes a second driving member 1311, a sliding frame 1312, a third driving member 1313, a lifting frame 1314, a fourth driving member 1315 and a translation frame 1316. The second driving member 1311 is installed on the frame 110 and connected to the sliding frame 1312. The second driving member 1311 is used to drive the sliding frame 1312 to move along the first direction. The third driving member 1313 is installed on the sliding frame 1312 and connected to the lifting frame 1314.

The fourth driving member 1315 is installed on the lifting frame 1314 and connected to the translation frame 1316. The fourth driving member 1315 is used to drive the translation frame 1316 to move along the third direction.

[0041] Specifically, the first driving member 132 is installed on the translation frame 1316, the second driving member 1311 can drive the first electric clamp 134 to move in the first direction through the sliding frame 1312, the third driving member 1313, the lifting frame 1314, the fourth driving member 1315, the translation frame 1316, the first driving member 132 and the rotating frame 133 in sequence, the third driving member 1313 can drive the first electric clamp 134 to move in the second direction through the lifting frame 1314, the fourth driving member 1315, the translation frame 1316, the first driving member 132 and the rotating frame 133 in sequence, the fourth driving member 1315 can drive the first electric clamp 134 to move in the third direction through the translation frame 1316, the first driving member 132 and the rotating frame 133 in sequence, the first direction, the second direction and the third direction are perpendicular to each other, so as to realize the flexible movement of the first electric clamp 134 in three-dimensional space and ensure the movement accuracy.

[0042] The transfer mechanism 140 includes a fifth driving member 141, a rotating platform 142, and a second electric clamp 143. The fifth driving member 141 is mounted on the frame 110 and connected to the rotating platform 142. The rotating platform 142 is provided with an extension block 144. The second electric clamp 143 is mounted on the extension block 144. The fifth driving member 141 is used to drive the second electric clamp 143 to rotate through the rotating platform 142. The second electric clamp 143 is used to realize the clamping or releasing function.

[0043] It is worth noting that the transfer mechanism 140 has four stations, namely the first station, the second station, the third station and the fourth station. When the transfer mechanism 140 is located at the first station, the second electric gripper 143 takes over the wound battery cell 200 from the first electric gripper 134; when the transfer mechanism 140 is located at the second station, the cutting mechanism 150 cuts the wound battery cell 200 clamped on the second electric gripper 143 to obtain the pre-processed battery cell 230; when the transfer mechanism 140 is located at the third station, the shelling mechanism 160 takes over the pre-processed battery cell 230 from the second electric gripper 143, and returns the obtained roll core 220 to the second electric gripper 143 after shelling and core extraction; when the transfer mechanism 140 is located at the fourth station, the unwinding mechanism 170 takes over the roll core 220 from the second electric gripper 143 and unwinds the roll core 220.

[0044] In this embodiment, the four workstations are arranged in sequence at intervals of 90 degrees. The fifth driving member 141 drives the second electric clamp 143 to rotate 90 degrees through the rotating table 142 to reach the next workstation, that is, the second electric clamp 143 at the first workstation rotates 90 degrees to reach the second workstation, the second electric clamp 143 at the second workstation rotates 90 degrees to reach the third workstation, the second electric clamp 143 at the third workstation rotates 90 degrees to reach the fourth workstation, and the second electric clamp 143 at the fourth workstation rotates 90 degrees to reach the first workstation.

[0045] In this embodiment, the number of the extension block 144 and the second electric gripper 143 are both four, and the four extension blocks 144 are arranged in a circular array on the outside of the rotating table 142, and each second electric gripper 143 is installed on an extension block 144, and the four second electric grippers 143 are used to realize the clamping or releasing function. Specifically, the four second electric grippers 143 work together to ensure that the four stations of the transfer mechanism 140 have a second electric gripper 143 at the same time. When the first second electric gripper 143 takes the wound battery cell 200 from the first electric gripper 134 at the first station, the second second electric gripper 143 clamps the wound battery cell 200 at the second station for cutting by the cutting mechanism 150, and the third second electric gripper 143 delivers the pre-treated battery cell 230 to the shelling mechanism 160 at the third station and receives the winding core 220, and the fourth second electric gripper 143 delivers the winding core 220 to the unwinding mechanism 170 at the fourth station. In this way, the feeding mechanism 130 , the cutting mechanism 150 , the shelling mechanism 160 and the unwinding mechanism 170 always keep in operation, further improving the recycling efficiency of the wound battery cell 200 .

[0046] The cutting mechanism 150 includes a sixth driving member 151, a telescopic platform 152, and two cutting assemblies 153. The sixth driving member 151 is mounted on the frame 110 and connected to the telescopic platform 152. The two cutting assemblies 153 are both mounted on the telescopic platform 152. The sixth driving member 151 is used to drive the telescopic platform 152 to move along the fourth direction to synchronously drive the two cutting assemblies 153 to approach or move away from the wound battery cell 200. The two cutting assemblies 153 are respectively used to cut one end cap of the wound battery cell 200. Specifically, when the sixth driving member 151 synchronously drives the two cutting assemblies 153 along the fourth direction through the telescopic table 152 to approach the wound battery cell 200, the two cutting assemblies 153 simultaneously cut off the two end covers of the wound battery cell 200 to obtain the pre-processed battery cell 230; when the sixth driving member 151 synchronously drives the two cutting assemblies 153 along the fourth direction through the telescopic table 152 to move away from the pre-processed battery cell 230, the two cutting assemblies 153 are reset at the same time to facilitate cutting the next wound battery cell 200.

[0047] The cutting assembly 153 includes a seventh driving member 1531, a moving frame 1532, an eighth driving member 1533 and a disc cutter 1534. The seventh driving member 1531 is mounted on the telescopic platform 152 and connected to the moving frame 1532. The seventh driving member 1531 is used to drive the moving frame 1532 to move along the fifth direction. The axial direction of the disc cutter 1534 is the fifth direction. The axial direction of the wound battery cell 200 is the same as the axial direction of the disc cutter 1534. The fifth direction is perpendicular to the fourth direction. The eighth driving member 1533 is mounted on the moving frame 1532 and connected to the disc cutter 1534.

At this time, the shelling mechanism 160 is started to perform the shelling process. During the operation of the shelling mechanism 160, first, the ninth driving member 161 drives the carrier frame 162 to approach or move away from the transfer mechanism 140 along the sixth direction to adjust the distance between the third electric clamp 165 and the pre-treated battery cell 230, and ensure that the stroke of the tenth driving member 163 is sufficient to drive the third electric clamp 165 to take over the pre-treated battery cell 230 from the second electric clamp 143; then the tenth driving member 163 drives the third electric clamp 165 to approach the pre-treated battery cell 230 along the sixth direction through the mounting frame 164 until the third electric clamp 165 clamps the pre-treated battery cell 230; then the second electric clamp 143 releases the pre-treated battery cell 230, and the tenth driving member 163 drives the pre-treated battery cell 230 along the sixth direction away from the transfer mechanism 140 through the mounting frame 164 and the third electric clamp 165 in turn until the pre-treated battery cell 230 moves to the second preset position, at which time the position of the pre-treated battery cell 230 corresponds to the position of the core pulling assembly 166; then the core pulling assembly 166 performs a core pulling process on the pre-treated battery cell 230 to make the core 220 escape from the sleeve 210, and completes the shelling process of the core 220. At this time, the core 220 is set on the core pulling component 166, and the sleeve 210 is clamped on the third electric clamp 165; then the third electric clamp 165 releases the sleeve 210 to make it fall naturally under the action of gravity; then the core pulling component 166 is reset to drive the core 220 back to the second preset position, at which time the core 220 is located at the third electric clamp 165; then the third electric gripper 165 clamps the roll core 220, and the tenth driving member 163 drives the third electric gripper 165 through the mounting frame 164 to approach the transfer mechanism 140 along the sixth direction until the second electric gripper 143 of the transfer mechanism 140 takes over the roll core 220 from the third electric gripper 165; finally, the tenth driving member 163 drives the third electric gripper 165 to reset through the mounting frame 164 to facilitate the shelling of the next pre-treated battery cell 230.

[0050] In this embodiment, the shelling mechanism 160 includes a ninth driving member 161, which is used to compensate for the stroke of the third electric clamp 165 in the sixth direction when the stroke of the tenth driving member 163 is insufficient, so as to ensure that the third electric clamp 165 can take over the pre-processed battery cell 230 from the second electric clamp 143, and ensure that the third electric clamp 165 can deliver the winding core 220 to the second electric clamp 143. However, this is not limited to this, and in other embodiments, the shelling mechanism 160 may not include the ninth driving member 161, and in this case, the stroke of the tenth driving member 163 is sufficient to ensure that the shelling process is carried out normally.
