Description

Technical Field

[0001] The present application relates to the field of battery recycling technology, for example, to a waste battery feeding system for the entire industry chain. Background Art

[0002] In the field of waste battery disassembly and recycling, after scrapped lithium batteries are disassembled into battery cells, they need to be discharged. To ensure safe processing and transportation, the battery terminals are manually insulated and affixed with insulating tape after discharge. Due to the large variety and size of discharged battery cells, they are manually packaged on plastic pallets, typically six layers of batteries, with individual battery models and specifications. The packaged pallets are then transferred to the aluminum shell battery crushing line for crushing and sorting, and the battery materials inside are recycled.

[0003] Currently, the battery feeding process at the front end of the aluminum-cased battery production line is largely manual. One operator uses a multimeter to measure the voltage of battery cells of varying sizes on the battery tray. Cells with voltages exceeding the upper limit are selected and re-discharged. Another operator then manually carries cells with voltages that meet the feeding requirements onto the conveyor belt at the front end of the aluminum-cased battery crushing line. These cells are then transported to the crusher for crushing and sorting. This feeding method requires at least two people and only processes discharged, insulated battery cells. Large-capacity battery cells weigh up to 5kg, making manual handling very labor-intensive. Furthermore, only one cell can be carried at a time, resulting in low feeding efficiency.

[0021] The technical solution of the present application is further described below in conjunction with the accompanying drawings and implementation methods. It is understood that the specific embodiments described herein are merely for the purpose of explaining the present application and are not intended to limit the present application. It should also be noted that, for ease of description, the accompanying drawings only show portions relevant to the present application, not all of them.

[0022] In the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed or detachable connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0023] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0024] In the process of sorting scrapped lithium batteries, in order to realize the automation of battery cell feeding, reduce the labor intensity of personnel and improve feeding efficiency, such as Figures 1-9 As shown, the present application provides a waste battery feeding system for the entire industry chain. The waste battery feeding system for the entire industry chain includes a support frame 100, a first conveyor line 200 and a second conveyor line 300.

[0025] Among them, a workbench 110 is rotatably arranged on the support frame 100, and the workbench 110 has a plurality of workstations, and a battery cell clamp 1 is fixedly arranged on each workstation. A rubber grinding device 2, a voltage measuring device 3, an insulation treatment device 5, a qualified cell grabbing device 6 and an unqualified cell grabbing device 7 are sequentially arranged on the support frame 100 along the circumference of the workbench 110. The rubber grinding device 2, the voltage measuring device 3, the insulation treatment device 5, the qualified cell grabbing device 6 and the unqualified cell grabbing device 7 are each arranged corresponding to one workstation; the first conveyor line 200 is arranged on one side of the qualified cell grabbing device 6, and the first conveyor line 200 is used to transport qualified battery cells to the aluminum shell battery production line for crushing; the second conveyor line 300 is arranged on one side of the unqualified cell grabbing device 7, and the second conveyor line 300 is used to transport unqualified battery cells to the recycling site for secondary discharge.

[0026] The waste battery feeding system is configured as follows: battery cells sequentially pass through a glue grinding device 2 to remove glue from the battery cell poles. A voltage measuring device 3 measures the pole voltage, and then the poles are insulated by an insulation treatment device 5. A qualified cell grabbing device 6 transfers battery cells with qualified voltages to a first conveyor line 200, and a failed cell grabbing device 7 transfers battery cells with unqualified voltages to a second conveyor line 300. This automated feeding of battery cells is achieved, reducing labor intensity and improving feeding efficiency. In this embodiment, a qualified battery cell has a voltage below 2.5 volts; otherwise, the battery cell voltage is considered unqualified.

[0027] In one embodiment, the waste battery feeding system further includes a detection device 4, which is fixedly mounted on the support frame 100 and located upstream of the rubber grinding device 2. The detection device 4 is communicatively connected to the rubber grinding device 2, the voltage measuring device 3, and the insulation treatment device 5. The detection device 4 is used to determine the position of the pole and can transmit the pole position information to the rubber grinding device 2, the voltage measuring device 3, and the insulation treatment device 5. The workstation directly opposite the detection device 4 can determine the position of the pole of the battery cell and transmit this position information to the rubber grinding device 2, the voltage measuring device 3, and the insulation treatment device 5 via a signal, thereby facilitating the rubber grinding device 2, the voltage measuring device 3, and the insulation treatment device 5 to accurately obtain the pole position and perform rubber grinding, voltage acquisition, and insulation treatment.

[0028] In one embodiment, the detection device 4 includes a detection frame 41 and a dimension measurement assembly. The detection frame 41 is fixedly mounted on the support frame 100. The dimension measurement assembly is fixedly mounted on the detection frame 41. The dimension measurement assembly is used to measure the length and height of the battery cell to obtain the center and height position of the pole. The dimension measurement assembly is communicatively connected to the rubber grinding device 2, the voltage measurement device 3, and the insulation treatment device 5. For example, the dimension measurement assembly includes a first laser ranging sensor 42 and a second laser measurement sensor 43, which respectively measure the length and height of the battery cell. The center and height position of the battery cell pole can then be obtained through calculation. Through the above arrangement, the pole position of the battery cell can be quickly obtained, and the measurement is accurate and convenient.

[0029] In one embodiment, the support frame 100 is provided with a driving member 120 that is transmission-connected to the workbench 110. The driving member 120 can drive the workbench 110 to rotate by an angle corresponding to one workstation at a time. For example, the driving member 120 in this application is a cam divider. The cam divider drives the workbench 110 to rotate according to a set angle. Each time it rotates one workstation, the work corresponding to each workstation is completed synchronously, and then the workbench 110 rotates to the next workstation. By adopting a ring-shaped arrangement, a cyclic operation can be achieved, and the angle of each rotation of the workbench 110 can be precisely controlled by the driving member 120, thereby ensuring that the work of the corresponding workstation can be effectively completed.

[0030] For example, in this embodiment, the workbench 110 is provided with eight workstations, six of which correspond to dimension inspection, rubber grinding, voltage measurement, insulation treatment, and qualified and unqualified monomer capture, while the remaining two are loading stations. In other embodiments, the number of workstations and their corresponding functions can be configured according to actual needs, and no further limitations are imposed here.

[0031] In one embodiment, a battery cell clamp 1 includes a first clamping assembly 11 and a second clamping assembly 12 disposed on a workbench 110. The first clamping assembly 11 is capable of clamping a battery cell along its length, while the second clamping assembly 12 is capable of clamping a battery cell along its width. For example, the first clamping assembly 11 includes a first clamping plate 112 and a second clamping plate 113 spaced apart along its length. The first clamping plate 112 is fixedly mounted on a fixed plate 13 of the workbench 110, while the second clamping plate 113 is slidably mounted on the fixed plate 13. A first clamping cylinder 111 is disposed on the workbench 110, and the piston rod of the first clamping cylinder 111 is connected to the second clamping plate 113. By controlling the piston rod of the first clamping cylinder 111 to extend or retract, the battery cell can be clamped or released along its length. The second clamping assembly 12 includes a third clamping plate 122 spaced apart along the width. The third clamping plate is fixedly mounted on the fixed plate 13, while the fourth clamping plate 122 is slidably mounted on the fixed plate 13. A second clamping cylinder 121 is mounted on the workbench 110. The piston rod of the second clamping cylinder 121 is connected to the fourth clamping plate 122. By controlling the piston rod of the second clamping cylinder 121 to extend or retract, the battery cells can be clamped or released along the width. During the clamping process, the second clamping cylinder 121 is actuated first in the width direction, followed by the first clamping cylinder 111 in the length direction, ensuring that battery cells of different sizes are centered after clamping. Proximity sensors are located at the center and height of the fixed plate 13 to detect whether the battery cells are properly positioned. This approach ensures stable clamping of the battery cells and ensures that the battery cells remain fixed relative to the workbench 110 during subsequent testing.

[0032] In one embodiment, to improve clamping efficiency, the first clamping plate 112 and the second clamping plate 113 can be slidably mounted on the fixed plate 13, a gear can be rotatably mounted on the fixed plate 13, and a rack that meshes with the gear can be fixedly mounted on both the second clamping plate 113 and the first clamping plate 112. When the first clamping cylinder 111 drives the second clamping plate 113 to move, the rack drives the gear, and the gear drives another rack, thereby bringing the first clamping plate 112 and the second clamping plate 113 closer together, allowing the battery cell to be quickly clamped. Similarly, the second clamping assembly 12 can also adopt a rack and gear structure, which will not be described in detail here.

[0033] In one embodiment, the rubber grinding device 2 includes a rubber grinding bracket 21, a first lifting assembly 22, a first lateral adjustment assembly 23, and a grinding assembly 24. The rubber grinding bracket 21 is fixedly mounted on the support frame 100, the first lifting assembly 22 is mounted on the rubber grinding bracket 21, the first lateral adjustment assembly 23 is transmission-connected to the first lifting assembly 22, and the grinding assembly 24 is transmission-connected to the first lateral adjustment assembly 23. The grinding assembly 24 is used to grind the pole. For example, the rubber grinding bracket 21 is L-shaped, and the first lifting assembly 22 includes a first servo motor 221 and a first lead screw 222. The first servo motor 221 is fixedly mounted on the horizontal end of the rubber grinding bracket 21, and the first lead screw 222 is arranged in a vertical direction. One end of the first lead screw 222 is transmission-connected to the output shaft of the first servo motor 221. The first lead screw 222 is transmission-connected to the first mounting plate 231. The first servo motor 221 can drive the first mounting plate 231 to move up and down via the first lead screw 222. The first lateral adjustment assembly 23 includes a second servo motor 232 and a second lead screw 233, which are arranged laterally. The second servo motor 232 is fixedly set on the first mounting plate 231, and the second lead screw 233 is rotatably set on the first mounting plate 231. The second lead screw 233 is transmission-connected to the second servo motor 232, and the second lead screw 233 includes a first section and a second section with opposite rotation directions. The grinding assembly 24 includes a first grinder 241 and a second grinder 242. The first grinder 241 is transmission-connected to the first section of the second lead screw 233, and the second grinder 242 is transmission-connected to the second section of the second lead screw 233. By controlling the rotation direction of the second servo motor 232, the first grinder 241 and the second grinder 242 can be controlled to move closer to or farther away from each other. By adjusting the distance between the first grinder 241 and the second grinder 242, the pole grinding and glue removal operations of battery cells of different sizes can be met. While ensuring the grinding efficiency, the reliability of the voltage measurement by the voltage measuring device 3 at the next workstation can be guaranteed.

[0034] In one embodiment, in order to ensure the smoothness of the lifting and lowering movement of the first mounting plate 231, a first guide shaft 25 is fixedly provided on the upper end surface of the first mounting plate 231. The first guide shaft 25 is arranged in the vertical direction, and the first guide shaft 25 is passed through the horizontal end of the grinding rubber bracket 21, playing a guiding role during the lifting and lowering movement of the first mounting plate 231.

[0035] In one embodiment, the voltage measuring device 3 includes a measuring bracket 31, a second lifting assembly 32, a second lateral adjustment assembly 33, and two measuring plates 34. The measuring bracket 31 is fixedly mounted on the support frame 100, the second lifting assembly 32 is mounted on the measuring bracket 31, and the second lateral adjustment assembly 33 is in transmission connection with the second lifting assembly 32. The two measuring plates 34 are transmission-mounted on the second lateral adjustment assembly 33. The second lateral adjustment assembly 33 is capable of adjusting the spacing between the two measuring plates 34 so that the measuring plates 34 can dock with the pole. For example, the measuring bracket 31 is L-shaped, and the second lifting assembly 32 includes a voltage measuring cylinder 321. The voltage measuring cylinder 321 is fixedly mounted on the horizontal end of the measuring bracket 31, and the cylinder piston rod 322 is arranged in a vertical direction. The cylinder piston rod 322 is connected to the second mounting plate 331. The voltage measuring cylinder 321 can drive the second mounting plate 331 to rise and fall by retracting and extending the cylinder piston rod 322. The second lateral adjustment assembly 33 includes a third servo motor 332 and a third lead screw 333, which are arranged transversely. The third servo motor 332 is fixedly mounted on the second mounting plate 331, while the third lead screw 333 is rotatably mounted on the second mounting plate 331. The third lead screw 333 is drivingly connected to the third servo motor 332. The third lead screw 333 includes a first section and a second section with opposite rotational directions. One measuring plate 34 is drivingly connected to the first section of the third lead screw 333, while the other measuring plate 34 is drivingly connected to the second section of the third lead screw 333. By controlling the rotation direction of the third servo motor 332, the two measuring plates 34 can be moved closer or further apart. By adjusting the spacing between the two measuring plates 34, the voltage of battery cells of different sizes can be measured, ensuring measurement efficiency.

[0036] In one embodiment, when the voltage measuring cylinder 321 drives the second mounting plate 331 to move downward so that the measuring plate 34 abuts against the pole, in order to ensure stable contact and thus ensure smooth voltage collection, a measuring head 342 is provided on the measuring plate 34, and a compression spring 341 is installed between the measuring head 342 and the measuring plate 34. When the measuring head 342 abuts against the pole, the compression spring 341 is deformed, and under the action of the elastic restoring force of the compression spring 341, the measuring head 342 is ensured to be in stable contact with the pole.

[0037] In one embodiment, in order to ensure the smoothness of the lifting and lowering movement of the second mounting plate 331, a second guide shaft 35 is fixedly provided on the upper end surface of the second mounting plate 331. The second guide shaft 35 is arranged in the vertical direction, and the second guide shaft 35 is passed through the horizontal end of the measuring bracket 31, playing a guiding role during the lifting and lowering movement of the second mounting plate 331.

[0038] In one embodiment, the insulation processing device 5 includes a processing bracket 51, a tape cutting assembly 52, and a gluing assembly 53. The processing bracket 51 is mounted on the support frame 100. The tape cutting assembly 52 and the gluing assembly 53 are both mounted on the support frame 100. The tape cutting assembly 52 is used to cut the insulating tape, and the gluing assembly 53 is used to adhere the cut insulating tape to one of the poles in the battery cell. For example, the processing bracket 51 is L-shaped. The tape cutting assembly 52 includes a mounting frame 522 and a cutting plate 523. The tape roll 521 is mounted on the mounting frame 522, which is fixed to the processing bracket 51. The cutting plate 523 is fixed to the front end of the mounting frame 522. The insulating tape on the tape roll 521 passes through the guide wheel on the mounting frame 522 and is then adhered to the cutting plate 523. The adhesive tape assembly 53 includes a first cylinder 533 mounted horizontally on the processing support 51 and a second cylinder 531 arranged vertically and slidably mounted on the horizontal end of the processing support 51. The piston rod of the first cylinder 533 is connected to the second cylinder 531, and the piston rod of the second cylinder 531 is equipped with a vacuum suction cup 532. Both the first cylinder 533 and the second cylinder 531 are double-stroke cylinders. During the adhesive tape application process, the second cylinder 531 first absorbs the insulating tape, then the piston rod of the first cylinder 533 retracts a first stroke to the cutting plate 523. The piston rod of the second cylinder 531 then moves down a first stroke, cutting the insulating tape on the cutting plate 523, leaving the remaining insulating tape adhered to the cutting plate 523. The piston rod of the first cylinder 533 then retracts to its second stroke, positioning the second cylinder 531 directly above the pole. The piston rod of the second cylinder 531 then moves downward a second stroke, applying the insulating tape to the pole, completing the taping process for the battery cell poles and ensuring the safety of subsequent feeding. The width of the insulating tape is set to 35mm, corresponding to the widest dimension of the pole. By applying the insulating tape to one end of the battery cell pole, the positive and negative terminals of the battery cell are prevented from short-circuiting, preventing short-circuit sparks on the first conveyor line 200 and ensuring safe feeding. The tape is suitable for insulating battery cells of varying sizes.

[0039] In one embodiment, to improve the accuracy of insulating tape application, the processing bracket 51 is slidably mounted on an adjustment seat 541 of the support frame 100. A stepper motor 54 is mounted on the adjustment seat 541. The stepper motor 54 is connected to the processing bracket 51 via a fourth lead screw. By controlling the stepper motor 54, the processing bracket 51 can be moved to adjust the position between the processing bracket 51 and the battery cell pole. This further improves the accuracy of adhesive application and can accommodate battery cells of different sizes. In other embodiments, the stepper motor 54 can also be a conventional motor or a servo motor, and no further restrictions are imposed here.

[0040] In one embodiment, the qualified battery cell grabbing device 6 includes a grabbing bracket 61, a lifting drive assembly 62, a transverse drive assembly 63, and a clamping jaw 64. The grabbing bracket 61 is fixedly mounted on the support frame 100, the lifting drive assembly 62 is mounted on the grabbing bracket 61, the transverse drive assembly 63 is transmission-connected to the lifting drive assembly 62, and the clamping jaw 64 is mounted on the transverse drive assembly 63 and transmission-connected to the transverse drive assembly 63. The clamping jaw 64 is used to grab the battery cell. For example, the lifting drive assembly 62 includes a longitudinal servo motor 621 and a longitudinal lead screw 622. The longitudinal servo motor 621 is fixedly mounted on the grabbing bracket 61, and the longitudinal lead screw 622 is rotatably mounted on the grabbing bracket 61 and connected to the output shaft of the longitudinal servo motor 621. The transverse drive assembly 63 includes a third mounting plate 631, a transverse servo motor 632, and a transverse lead screw 633. The third mounting plate 631 is in driving connection with the longitudinal lead screw 622. The transverse servo motor 632 is fixedly mounted on the third mounting plate 631. The transverse lead screw 633 is rotatably mounted on the third mounting plate 631, and one end of the transverse lead screw 633 is connected to the output shaft of the transverse servo motor 632. A clamping jaw 64 is drivingly mounted on the transverse lead screw 633. The clamping jaw 64 includes a clamping seat 641, a clamping cylinder 642, and a clamping plate 643. The clamping seat 641 is drivingly mounted on the transverse lead screw 633, the clamping cylinder 642 is fixedly mounted on the clamping seat 641, and the clamping plate 643 is fixedly mounted on the piston rod of the clamping cylinder 642. By controlling the transverse servo motor 632 and the longitudinal servo motor 621, the clamping claw 64 is driven to the clamping position, and then the clamping cylinder 642 is actuated to clamp the battery cell through the clamping plate 643. Then, by controlling the transverse servo motor 632 and the longitudinal servo motor 621, the battery cell is transferred to the first conveyor line 200, and the clamping cylinder 642 releases the battery cell, so that the battery cell is transplanted onto the first conveyor line 200. In the above manner, battery cells with qualified voltage can be automatically transferred to the first conveyor line 200 for subsequent crushing operations, which reduces the labor intensity of workers and improves work efficiency. In order to ensure the smooth movement of the transverse drive assembly 63, a slide rail slider structure is provided between the side of the third mounting plate 631 away from the clamping claw 64 and the grabbing bracket 61. In order to ensure the smooth movement of the clamping claw 64, a slide rail slider structure is also provided between the clamping seat 641 and the third mounting plate 631.

[0041] In one embodiment, the structure of the unqualified cell grabbing device 7 is the same as that of the qualified cell grabbing device 6, which will not be described in detail. By providing the unqualified cell grabbing device 7, battery cells with unqualified voltage can be transferred to the second conveyor line 300 for further discharge.

[0042] In one embodiment, the waste battery feeding system further includes a battery tray lifting device 400, located on one side of the support frame 100 and used to carry battery cells to be sorted. For example, the battery tray lifting device 400 utilizes a commonly used hydraulic scissor-type lifting mechanism. A forklift places a battery tray containing discharged battery cells onto the battery tray lifting device 400 and then moves it near the support frame 100. A worker controls the height and position of the battery tray lifting device 400 to facilitate manual grasping of the battery cells and placing them on the battery cell fixture 1.

[0043] The working process of this waste battery feeding system is as follows:

[0044] Workers load the battery cells on the battery tray lifting device 400 to the empty loading station. The battery cell clamp 1 clamps the battery cell, and then the workbench 110 rotates one station in turn. The battery cell arrives at the detection device 4 for size measurement, arrives at the rubber grinding device 2 for rubber grinding of the pole, and then arrives at the voltage measuring device 3 for voltage measurement. The pole is insulated at the insulation treatment device 5. Finally, the qualified cell grabbing device 6 transfers the battery cells with qualified voltage to the first conveyor line 200, and then to the aluminum shell line crusher for crushing. After subsequent sorting processes, battery powder, diaphragm paper, aluminum shell and other materials are sorted out. Unqualified battery cells continue to move to the next station and are transferred to the second conveyor line 300 by the unqualified cell grabbing device 7. During this process, as the workbench 110 rotates, inspection and sorting can be carried out continuously, and workers can continue to load materials.

[0045] The average weight of a battery cell is calculated as 2 kg, and the feeding frequency is set to 800 times per hour. The feeding production efficiency can reach 1.6 tons per hour. The general manual feeding process has a production capacity of only 1 ton, and the feeding capacity has been increased by 60%. The feeding process does not require manual pole insulation and voltage measurement, which can reduce the labor cost of the feeding method.

[0046] This waste battery feeding system can realize the automatic feeding operation of waste batteries in the field of lithium battery monomer disassembly and recycling. It is suitable for orderly, automatic and continuous feeding of battery monomers of various specifications and sizes. It is easy to operate and use, has low labor intensity, and reduces the labor cost of feeding on the production line. For retired battery monomers with residual glue on the pole after discharge, some batteries are not fully discharged or the voltage rebounds, no manual processing is required. The equipment can realize automatic processing, ensuring the safety of feeding on the aluminum shell battery production line. It is suitable for promotion and application in the field of lithium battery recycling and production manufacturing.

[0047] The embodiment of the present application provides a waste battery feeding system for the entire industrial chain. A workbench is rotatably mounted on a support frame. The workbench has multiple workstations, each of which is equipped with a battery cell clamp. A rubber grinding device, a voltage measuring device, an insulation treatment device, a qualified cell grabbing device, and an unqualified cell grabbing device are sequentially arranged on the support frame along the circumference of the workbench. A first conveyor line is arranged on one side of the qualified cell grabbing device, and a second conveyor line is arranged on the other side of the unqualified cell grabbing device. When feeding, the battery cell is first manually transferred to the battery cell clamp, and then the workbench is started to rotate. The workbench drives the battery cell clamp with the battery cell clamped therein to grind the rubber, detect the voltage, and perform pole insulation treatment at the rubber grinding device, voltage measuring device, and insulation treatment device in sequence. Finally, if the voltage test of the battery cell is qualified, the battery cell is transferred to the first conveyor line for crushing by the qualified cell grabbing device. If the voltage test of the battery cell is unqualified, the workbench continues to rotate one workstation to the unqualified cell grabbing device, and the unqualified cell grabbing device transfers the unqualified cell to the second conveyor line for re-discharging. During this process, as the workbench rotates, continuous inspection and sorting can be performed, and workers can continuously load materials. Through the above method, the automatic operation of battery cell feeding is realized, which reduces the labor intensity of personnel and improves feeding efficiency.
