Description

Technical Field

[0001] This invention belongs to the technical field of waste lithium battery recycling and processing equipment, specifically relating to a batch puncture treatment device for waste lithium batteries before discharge. Background Technology

[0002] Waste lithium batteries refer to lithium batteries that can no longer meet usage requirements. They are widely used in new energy vehicles, consumer electronics, and energy storage devices. Since waste lithium batteries usually have a certain amount of residual charge inside, if they are directly disassembled and recycled, the residual charge may cause safety accidents such as short circuits, overheating, fires, or even explosions. It may also interfere with the normal operation of subsequent resource utilization processes. Therefore, they need to be discharged first to eliminate the hidden dangers of residual charge. The purpose of batch puncture treatment before discharge is to break the battery cell structure by puncturing, so that the positive and negative electrodes and electrolyte inside the battery form an effective conductive path, which facilitates the rapid, uniform, and thorough release of residual charge in subsequent discharge processes.

[0003] Currently, most waste lithium battery pre-discharge puncture processing devices on the market involve placing the waste lithium batteries and using puncture components to perform the puncture operation. Square lithium batteries can be directly positioned and punctured, but round waste lithium batteries are prone to rolling during placement, resulting in puncture position deviation, poor puncture effect, and even potential safety hazards due to puncture deviation. Even if clamping puncture is used, each battery needs to be positioned and clamped individually, making it difficult for the overall processing efficiency to meet the needs of large-scale industrial recycling. Summary of the Invention

[0004] The purpose of this invention is to provide a batch puncture treatment device for waste lithium batteries before discharge, which can perform mechanized and precise puncture operations on round waste lithium batteries, realize integrated automation of the process, reduce manual intervention costs and labor intensity, and meet the needs of large-scale industrial batch recycling and processing.

[0008] Preferably, the movable puncture assembly includes a fourth grooved wheel rotatably connected to the side of the support plate away from the disc, one side of the fourth grooved wheel being fixedly connected to a rotating rod, a fifth grooved wheel rotatably connected to the bottom of one side of the support plate, a second belt rotatably connected to the surface of the fifth grooved wheel, one end of the second belt away from the fifth grooved wheel being rotatably connected to the fourth grooved wheel, a third gear fixedly connected to one side of the fifth grooved wheel, N-shaped rods fixedly connected to opposite sides of the two support plates, T-shaped rods slidably connected to the surface of the N-shaped rods, one bottom side of one of the T-shaped rods meshing with one side of the third gear, a round rod fixedly connected to the bottom of the two T-shaped rods on the side closer to each other, a plurality of forks fixedly connected to the bottom of the round rod, and a baffle fixedly connected to the side of the two T-shaped rods on the side closer to each other and directly above the forks.

[0009] Preferably, a plurality of railings for use with the fork are fixedly connected to the top side of the slide rail, the swing rod has an L-shaped arc structure, and the slide groove has a semi-arc structure.

[0010] Preferably, the rotating output assembly includes support blocks fixedly connected to both sides of the bottom of the inner cavity of the support box. Conveyor rollers are rotatably connected to the side of the two support blocks that are close to each other and to the inner cavity of the output housing, respectively. Conveyor belts are rotatably connected to the surfaces of the two conveyor rollers. Multiple sets of rectangular rods are fixedly connected to the surface of the conveyor belts. A sixth grooved wheel is rotatably connected to the inner wall of the support box. A fourth gear is fixedly connected to one side of the sixth grooved wheel. A drive shaft is rotatably connected to the side of the support box and the support blocks that are close to each other.

[0012] Preferably, one end of the support housing is connected to an inlet valve, and one end of the bottom of the output housing is connected to an outlet valve.

[0013] The technical effects achieved by this invention are as follows: This invention discloses a batch puncture treatment device for waste lithium batteries before discharge. An operator places multiple round waste lithium batteries into the conveying housing through the top opening. A control panel drives a motor to rotate a rotating rod, which in turn drives a second gear. The meshing of the second and first gears drives a turntable to rotate slowly within the conveying housing. The turntable's grooves guide the round waste lithium batteries sequentially to the bottom opening of the conveying housing. With each rotation of the rotating rod, the turntable rotates only a quarter turn, causing the round waste lithium batteries to fall one by one into a sliding seat. Simultaneously, the rotating rod drives a third grooved wheel to rotate. A first belt links the second and third grooved wheels and the turntable to rotate. A slider on the turntable slides along the groove of a swing rod, achieving both static reception and reciprocating pushing of the sliding seat on the slide rail. This precisely receives the falling round waste lithium batteries and delivers them to the puncture position. The rotating rod then drives a fourth... The rotating pulley, via the second belt, drives the fifth pulley and the third gear, which in turn drive the T-shaped rod to slide along the N-shaped rod. This allows the fork to precisely puncture the round waste lithium batteries under the constraint of the baffle. After puncture, the baffle intercepts the round waste lithium batteries, causing them to fall into the output casing. Power is transmitted through the first pulley, which in turn drives the third belt, the sixth pulley, the fourth gear, and the fifth gear, driving the conveyor roller to rotate the conveyor belt. The rectangular rods then transport the round waste lithium batteries in an orderly manner. The output plate then sends the round waste lithium batteries out of the support box for centralized collection. Simultaneously, the conductive liquid replenished through the inlet valve ensures that the conductive liquid makes full contact with the punctured round waste lithium batteries, thereby improving discharge efficiency. This device can perform mechanized and precise puncture operations on round waste lithium batteries, achieving integrated automation of the process, reducing manual intervention costs and labor intensity, and meeting the needs of large-scale industrial batch recycling.

[0016] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to the accompanying drawings. It should be understood that the following text is merely used to describe one or more specific embodiments of this invention and does not strictly limit the scope of protection specifically claimed by this invention.

[0017] like Figure 1 - Figure 9 As shown, a batch puncture treatment device for waste lithium batteries before discharge includes a support box 1. A control panel is fixedly installed on one side of the support box 1. A conveying shell 2 is fixedly connected to the top of the inner cavity of the support box 1. An output shell 3 is fixedly connected to the bottom of the inner cavity of the support box 1. Two support plates 4 are fixedly connected to the top of the inner cavity of the support box 1 and to both sides near the conveying shell 2. A rotating rod 5 is rotatably connected to one side of the support plate 4. A motor 6 is fixedly installed on one side of the support box 1. The output end of the motor 6 is fixedly connected to the rotating rod 5. Multiple round waste lithium batteries 11 are placed in the inner cavity of the conveying shell 2.

[0018] The round waste lithium batteries 11 are subjected to batch puncture treatment before discharge for safety and subsequent processing efficiency. Since there may be residual charge inside the round waste lithium batteries 11, there is a risk of short circuit, fire or even explosion if they are directly disassembled or processed. Batch puncture treatment can effectively release the residual charge inside the lithium batteries, reduce the safety risks in the processing process, and facilitate discharge, disassembly and recycling operations, thereby improving the overall processing efficiency.

[0019] The control panel has multiple control buttons, which operators can use to start or stop the device. The support box 1 provides a stable support structure for the entire device, ensuring that the device will not shake or shift during operation. The conveying shell 2 and the output shell 3 respectively protect and guide the conveying and output processes, preventing the round waste lithium batteries 11 from falling or deviating from the track during conveying and output. The support plate 4 provides an installation base for the moving piercing component. The drive motor 6 can drive the rotating rod 5 to rotate, which in turn drives the second gear 10 and the turntable 7 to rotate, causing the round waste lithium batteries 11 to fall into the receiving and pushing component, and transporting the round waste lithium batteries 11 to the designated position to cooperate with the moving piercing component to accurately pierce the round waste lithium batteries 11. The rotating output component is used to send the round waste lithium batteries 11 out of the support box 1 for collection.

[0020] The conveying housing 2 is equipped with a rotating packing assembly, which can automatically arrange and rotate the round waste lithium batteries 11 in an orderly manner, enabling indirect transportation of the round waste lithium batteries 11, reducing manual intervention and labor intensity.

[0021] like Figure 3 As shown, the rotating packing assembly includes a turntable 7 rotatably connected to the bottom of the inner cavity of the conveying housing 2. The turntable 7 has a rotating groove 8. A first gear 9 is rotatably connected to the bottom of one side of the conveying housing 2 and located in the inner cavity of the support box 1. One side of the first gear 9 is fixedly connected to the turntable 7. A second gear 10 is fixedly connected to one end of the rotating rod 5 near the first gear 9. One side of the second gear 10 meshes with one side of the first gear 9.

[0022] Specifically, multiple round waste lithium batteries 11 are placed into the device through the opening at the top of the conveying housing 2. Then, the control panel drives the motor 6 to rotate the rotating rod 5 in an orderly manner. The power generated by the rotation of the rotating rod 5 is transmitted to the second gear 10. The second gear 10 meshes with the first gear 9, causing the first gear 9 to rotate in the opposite direction. This, in turn, drives the turntable 7 to rotate at the bottom of the inner cavity of the conveying housing 2. When the turntable 7 rotates, the rotating groove 8 on it can move the round waste lithium batteries 11, so that they fall more accurately into the receiving and pushing component.

[0023] When the rotating rod 5 rotates one revolution, the second gear 10 also rotates one revolution, but the first gear 9 drives the turntable 7 to rotate only one-quarter of the way, so that the round waste lithium battery 11 gradually moves to the bottom opening of the conveying shell 2 under the drive of the rotating groove 8. According to the sliding seat 24 described below, the round waste lithium battery 11 falls into the sliding seat 24.

[0024] The support box 1 is equipped with a receiving and pushing component, which can receive the round waste lithium battery 11 conveyed by the rotating packing component and accurately push it to the preset puncture position to ensure the accuracy and efficiency of the puncture operation.

[0025] like Figure 4 and Figure 5 As shown, the receiving and pushing assembly includes a first grooved wheel 12 rotatably connected to one side of the inner cavity of the support box 1; a second grooved wheel 13 fixedly connected to one side of the first grooved wheel 12; a third grooved wheel 14 fixedly connected to the rotating rod 5 near the surface of the support box 1; a first belt 15 rotatably connected to the surface of the second grooved wheel 13; the end of the first belt 15 away from the second grooved wheel 13 rotatably connected to the third grooved wheel 14; a disc 16 fixedly connected to one side of the second grooved wheel 13; and a rotating rod 17 rotatably connected to the side of the support box 1 and the support plate 4 that are close to each other. A swing rod 18 is fixedly connected to the surface of the rod 17. A groove 19 is provided on the swing rod 18. A slider 20 is fixedly connected to the side of the disc 16 near the support plate 4. The slider 20 is slidably inserted into the groove 19. A connecting rod 21 is rotatably connected to the end of the swing rod 18 away from the rotating rod 17. A connecting block 22 is rotatably connected to the end of the connecting rod 21 away from the swing rod 18. A slide rail 23 is fixedly connected to the bottom of the inner cavity of the support box 1. A sliding seat 24 is slidably connected to the slide rail 23. One side of the connecting block 22 is fixedly connected to one side of the sliding seat 24.

[0026] As described above, the control panel drive motor 6 drives the rotating rod 5 to rotate. A third grooved wheel 14 is fixedly connected to the surface of the rotating rod 5, causing the third grooved wheel 14 to rotate synchronously with the rotating rod 5. A first grooved wheel 12 is rotatably connected to the inner wall of the support housing 1, and a second grooved wheel 13 is fixedly connected to one side of it. The surfaces of the second grooved wheel 13 and the third grooved wheel 14 are rotatably connected via a first belt 15. Therefore, the rotation of the third grooved wheel 14 synchronously drives the second grooved wheel 13 and the first grooved wheel 12 to rotate on one side of the inner wall of the support housing 1, and also drives the second grooved wheel 13 to rotate. The side disc 16 rotates, and the rotation of the disc 16 will drive the slider 20 to rotate synchronously. The slider 20 is slidably connected to the groove 19 on the swing rod 18. Therefore, the rotation of the slider 20 will cause the swing rod 18 to drive the rotating rod 17 to use the inner wall of the support box 1 as the rotation point, so that the swing rod 18 swings against the disc 16 and pushes the bottom connecting rod 21 to move, thereby driving the connecting block 22 and the sliding seat 24 to push forward on the top of the slide rail 23. The end of the slide rail 23 near the moving piercing component is in a hollow state, so that the support box 1 is connected to the inner cavity of the output shell 3.

[0027] As described above, a full rotation of the rotating rod 5 causes the turntable 7 to rotate a quarter turn, causing the circular waste lithium battery 11 to fall from the opening at the bottom of the conveying housing 2 into the sliding seat 24. Simultaneously, a full rotation of the rotating rod 5 also causes the disc 16 to rotate once. When the slider 20 is at the top of one side of the disc 16, the rotation of the disc 16 causes the slider 20 to move downwards to approximately two-quarters of the circumference of the disc 16. At this point, the slider 20 slides within the groove 19 and does not cause the swing rod 18 to move. The sliding seat 24 is located at the bottom opening of the conveying housing 2, facilitating the receipt of the circular waste lithium battery 11. At this time, the turntable 7 rotates synchronously, causing the circular waste lithium battery 11 to fall into the sliding seat 24. When the rotation of the disc 16 causes the slider 20 to move to approximately three-quarters of the circumference of the disc 16... When the disk is in position, the swing rod 18 will swing against the disk 16, and the connecting rod 21 and connecting block 22 at the bottom will move accordingly, thereby pushing the sliding seat 24 forward on the slide rail 23. At the same time, the circular waste lithium battery 11 in the sliding seat 24 will be pushed forward, so that the moving piercing component can pierce the circular waste lithium battery 11. After the piercing is completed, when the rotation of the disk 16 causes the slider 20 to move to a position close to four-quarters of the circumference of the disk 16, the slider 20 slides in the slide groove 19. At this time, the swing rod 18 will swing back to the initial position against the disk 16. This process is repeated, so that while the sliding seat 24 moves back and forth on the top of the slide rail 23, the circular waste lithium battery 11 in the conveying shell 2 is sequentially conveyed to the moving piercing component for piercing.

[0028] The support plate 4 is equipped with a mobile piercing component that works in conjunction with the receiving and pushing component. The mobile piercing component can quickly and accurately pierce the round waste lithium battery 11 while the receiving and pushing component pushes it. It can also remove the pierced round waste lithium battery 11 from the piercing position, making it easier to carry out the next round of pushing and piercing operations, thereby improving work efficiency.

[0029] like Figure 6 and Figure 7The movable puncture assembly includes a fourth grooved wheel 25 rotatably connected to the side of the support plate 4 away from the disc 16. One side of the fourth grooved wheel 25 is fixedly connected to the rotating rod 17. A fifth grooved wheel 26 is rotatably connected to the bottom of one side of the support plate 4. A second belt 27 is rotatably connected to the surface of the fifth grooved wheel 26. One end of the second belt 27 away from the fifth grooved wheel 26 is rotatably connected to the fourth grooved wheel 25. A third gear 28 is fixedly connected to one side of the fifth grooved wheel 26. An N-shaped rod 29 is fixedly connected to the opposite side of the two support plates 4. A T-shaped rod 30 is slidably connected to the surface of the N-shaped rod 29. One bottom side of one of the T-shaped rods 30 is meshed with one side of the third gear 28. A round rod 31 is fixedly connected to the bottom of the side of the two T-shaped rods 30 that is close to each other. A plurality of forks 32 are fixedly connected to the bottom of the round rod 31. A baffle 33 is fixedly connected to the side of the two T-shaped rods 30 that is close to each other and directly above the forks 32.

[0030] Specifically, the rotation of the disc 16 causes the slider 20 to slide within the groove 19 on the swing rod 18, thereby causing the swing rod 18 to swing along the inner wall of the support box 1 following the rotating rod 17. At the same time, the rotating rod 17 drives the fourth grooved wheel 25, which is fixedly connected to it, to complete a rotation of nearly 45 degrees. Since the rotation direction of the fourth grooved wheel 25 is opposite to the swing direction of the swing rod 18, it drives the fifth grooved wheel 26 to rotate via the second belt 27. The rotation of the fifth grooved wheel 26 further drives the third gear 28 to rotate, causing the T-shaped rod 30, which is meshed with the third gear 28, to slide on the N-shaped rod 29, thereby causing the round rod 31 on the T-shaped rod 30 to push the fork 32 and the baffle 33 toward the sliding seat 24. As the swing lever 18 swings and moves the sliding seat 24 forward, the fork 32 and the baffle 33 move closer to the sliding seat 24 under the drive of the T-shaped rod 30, so that the fork 32 can puncture the circular waste lithium battery 11 on the sliding seat 24. The baffle 33 is used to limit the circular waste lithium battery 11 and prevent it from moving upward during puncture. When the swing lever 18 moves the sliding seat 24 back to its original position, the rotation direction of the fourth grooved wheel 25 is still opposite to the swing direction of the swing lever 18. The third gear 28 rotates in the opposite direction with the fourth grooved wheel 25. Therefore, the fork 32 and the baffle 33 will also be reset under the drive of the T-shaped rod 30, thus preparing for the next puncture operation and improving work efficiency.

[0031] like Figure 5 and Figure 8 As shown, multiple railings 34 that cooperate with the fork 32 are fixedly connected to the top side of the slide rail 23. The swing rod 18 has an L-shaped arc structure, and the slide groove 19 has a semi-arc structure.

[0032] As described above, the railing 34 is used to intercept the punctured circular waste lithium battery 11 while the T-shaped bar 30 is resetting, so that the punctured circular waste lithium battery 11 can be removed from the fork bar 32 and fall into the output housing 3. The L-shaped arc-shaped swing bar 18 and the semi-arc-shaped slide groove 19 cooperate with each other, so that the swing bar 18 can complete the stationary and pushing action of the sliding seat 24 when the disc 16 drives the slider 20 to rotate, and at the same time can move the fork bar 32 to puncture and reset.

[0033] The output housing 3 is equipped with a rotating output component, which can transport the punctured circular waste lithium battery 11 out of the collection area outside the support box 1, realizing the automated collection and sorting of waste lithium batteries and providing convenience for subsequent processing.

[0034] like Figure 2 and Figure 9 As shown, the rotating output assembly includes support blocks 35 fixedly connected to both sides of the bottom of the inner cavity of the support housing 1. Conveyor rollers 36 are rotatably connected to the side of the two support blocks 35 that are close to each other and to the inner cavity of the output housing 3. Conveyor belts 37 are rotatably connected to the surfaces of the two conveyor rollers 36. Multiple sets of rectangular rods 38 are fixedly connected to the surface of the conveyor belts 37. A sixth grooved wheel 39 is rotatably connected to the inner wall of the support housing 1. A fourth gear 40 is fixedly connected to one side of the sixth grooved wheel 39. A drive shaft 41 is rotatably connected to the side of the support housing 1 and the support blocks 35 that are close to each other. One end of the drive shaft 41 is fixedly connected to one of the conveyor rollers 36. A fifth gear 42 is fixedly connected to the surface of the drive shaft 41. The fourth gear 40 and the fifth gear 42 are meshed. A third belt 43 is rotatably connected to the surface of the sixth grooved wheel 39. The end of the third belt 43 away from the sixth grooved wheel 39 is rotatably connected to the first grooved wheel 12.

[0035] Specifically, as described above, the control panel drive motor 6 drives the rotating rod 5 to rotate, which in turn causes the third grooved wheel 14 on the rotating rod 5 to rotate synchronously. Since the second grooved wheel 13 and the third grooved wheel 14 are rotatably connected through the first belt 15, the second grooved wheel 13 rotates accordingly, further driving the first grooved wheel 12 to rotate. The first grooved wheel 12 and the fourth gear 40 are rotatably connected through the sixth grooved wheel 39 and the third belt 43. Therefore, the rotation of the first grooved wheel 12 will drive the fourth gear 40 to rotate. The fourth gear 40 meshes with the fifth gear 42, and the rotation of the fourth gear 40 will drive the fifth gear 42 to rotate in the opposite direction, thereby driving the transmission shaft 41, which is fixedly connected to the fifth gear 42, to rotate along the support housing 1. The inner wall rotates in the opposite direction, simultaneously driving the conveyor roller 36, which is fixedly connected to the drive shaft 41, to rotate. During this process, the rectangular rod 38 rotates on the two conveyor rollers 36 along with the conveyor belt 37, causing the round waste lithium batteries 11 that have been pierced from the inner cavity of the support box 1 to fall onto the conveyor belt 37. Limited by the rectangular rod 38, they are arranged in an orderly manner on the conveyor belt 37 and conveyed to the top of the conveyor belt 37. Since the output plate 45 and the rectangular rod 38 are arranged in an alternating manner, the output plate 45 will intercept the round waste lithium batteries 11 on the conveyor belt 37 and the rectangular rod 38 and output them to the outside of the support box 1, effectively avoiding the situation where the round waste lithium batteries 11 after piercing are chaotically piled up during the conveying process.

[0036] like Figure 2 The support box 1 has a rectangular hole 44 at one end. A plurality of output plates 45 that cooperate with the rectangular rod 38 are fixedly connected to the side of the support box 1 near the rectangular hole 44. The output plates 45 have an inclined structure. Each support block 35 has an anti-deviation plate 46 fixedly connected to its top.

[0037] The design of the rectangular hole 44 and the output plate 45 facilitates the transport of the circular waste lithium batteries 11 on the conveyor belt 37 to the outside of the support box 1 for centralized processing via the output plate 45. At the same time, the inclined structure of the output plate 45 can better guide the circular waste lithium batteries 11 to slide, improving the output efficiency. The design of the anti-deviation plate 46 is used to limit and block the circular waste lithium batteries 11, preventing them from shifting, so that the end of the circular waste lithium batteries 11 that leaves the conveyor belt 37 can smoothly slide out of the support box 1 via the output plate 45.

[0038] like Figure 1 As shown, one end of the support housing 1 is connected to an inlet valve 47, and one end of the bottom of the output housing 3 is connected to an outlet valve 48.

[0039] Specifically, the inlet valve 47 is used to replenish the conductive liquid to the bottom of the inner cavity of the support box 1 and the inner side of the output housing 3. The connection design between the outlet valve 48 and the output housing 3 allows the conductive liquid to be discharged as needed. The amount of conductive liquid should be just enough to cover the top of the sliding seat 24, so that it can fully contact the circular waste lithium battery 11 during puncture, ensuring good conductivity during puncture and improving discharge efficiency.
