Description

Technical Field

[0001] This utility model belongs to the field of lithium battery discharge technology, and in particular relates to a rapid discharge device for lithium battery recycling. Background Technology

[0002] Discharging lithium batteries before recycling is a crucial step in the lithium battery recycling process. Lithium batteries typically retain some residual charge after use. Without proper discharge, these batteries may experience thermal runaway, fire, or even explosion during recycling, transportation, and dismantling due to factors such as compression, impact, or short circuits. Pre-discharging significantly reduces the internal energy of the battery, minimizing safety hazards and ensuring the safety of recycling personnel and their working environment.

[0003] When discharging lithium batteries, puncture discharge and immersion discharge can be used. However, puncture discharge has low safety and is prone to fire and explosion. Immersion discharge is prone to polluting water sources. When using a discharge box to discharge through resistance, staff need to frequently take out and put in the lithium battery, which is troublesome and time-consuming, resulting in low overall discharge efficiency. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a rapid discharge device for lithium battery recycling, which more accurately solves the problems described above.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model proposes a rapid discharge device for lithium battery recycling, including a placement rack. Two vertical plates are fixedly connected to the upper surface of the placement rack, and a sliding plate is slidably connected between the two vertical plates. Multiple first electrode posts are fixedly connected to the sliding plate, and multiple second electrode posts are fixedly connected to the upper surface of the placement rack. The first electrode posts and the second electrode posts are opposite each other. A first wire is connected between two adjacent first electrode posts, and a second wire is connected between two adjacent second electrode posts. A wire-wound resistor is fixedly connected to the upper surface of the placement rack, and a third wire is connected to both ends of the wire-wound resistor. Two third wires are respectively connected to the second wires and the first wires. A feeding assembly is provided on the placement rack.

[0007] In one example, the upper surface of the sliding plate and the lower surface of the placement frame are both fixedly connected to an insulating housing, and the two third wires respectively pass through the insulating housing.

[0008] In one example, the feeding assembly includes four support columns, which are fixedly connected to the placement frame. The four support columns are opposite each other in pairs, and a crossbar is fixedly connected between the two opposite support columns. Each of the two vertical plates has a square groove on one side. The crossbar passes through the square groove and is fixedly connected to the vertical plate. Sliding rods are slidably connected to the two crossbars. Multiple horizontal plates are fixedly connected between the two sliding rods. Each horizontal plate has multiple arrays of circular through slots. The number of circular through slots on each horizontal plate is the same as the number of the first electrode column and the second electrode column, and their positions are opposite.

[0009] In one example, a rack is fixedly connected to the lower surface of one of the sliding rods, and a mounting plate is fixedly connected to one side of the vertical plate near the rack. A first servo motor is mounted on one side of the mounting plate, and a gear is fixedly connected to the spindle of the first servo motor, with the gear meshing with the rack.

[0010] In one example, the sliding plate passes through two vertical plates, one of which is fixedly connected to two support plates on one side, and one of which is fixedly connected to a second servo motor on one side. The main shaft of the second servo motor is fixedly connected to a threaded rod, which passes through the sliding plate upward and is threadedly connected to the sliding plate.

[0011] In one example, the upper surface of the placement rack is fixedly connected to a fixing plate on one side of the sliding plate. The upper surface of the fixing plate is provided with multiple square grooves, the width of which is the same as the diameter of the second electrode post. The fixing plate is provided with multiple circular through holes. The second electrode post is located in the square groove, and the upper surface of the second electrode post and the bottom surface of the square groove are on the same horizontal plane.

[0012] In one example, the upper surface of the placement rack is provided with a square through groove on the other side of the sliding plate. A placement box is fixedly connected in the square through groove. An inclined plate is fixedly connected between the two vertical plates. The inclined plate is located above the square through groove, and the overall height of the inclined plate is higher than that of the horizontal plate.

[0013] The lithium battery recycling and rapid discharge device proposed in this utility model can bring the following beneficial effects:

[0014] Firstly, by setting up a feeding assembly, the horizontal plate moves to below the sliding plate. At this time, all the negative terminals of the lithium batteries on the horizontal plate are in contact with the second electrode post. The second servo motor drives the threaded rod to rotate, the sliding plate descends, and the first electrode post descends. The first electrode post and the second electrode post clamp and discharge the lithium batteries. After the lithium batteries on one horizontal plate have finished discharging, the sliding rod continues to move, causing the discharged lithium batteries to slide and misalign with the sliding plate, so that the lithium batteries on the second horizontal plate move above the second electrode post for discharge. This allows for the replacement of the lithium batteries as a whole, making feeding more convenient and faster, eliminating the need for staff to replace them one by one. This helps to speed up the overall discharge speed of lithium batteries and save time.

[0015] Secondly, by setting up a placement box, when the lithium battery is fully discharged and moves to the upper surface of the placement box, it falls into the placement box for collection under the action of gravity. If the lithium battery gets stuck on the horizontal plate and cannot be detached, when the horizontal plate continues to move, the upper end of the lithium battery contacts the inclined plate. Under the pressure of the inclined plate, the lithium battery is detached from the horizontal plate. By setting up the inclined plate, the lithium battery can be detached, making it convenient to collect the lithium battery. Attached Figure Description

[0023] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0024] like Figures 1-4As shown, an embodiment of this utility model proposes a rapid discharge device for lithium battery recycling, including a placement rack 1. Two vertical plates 2 are fixedly connected to the upper surface of the placement rack 1, and a sliding plate 3 is slidably connected between the two vertical plates 2. Multiple first electrode posts 4 are fixedly connected to the sliding plate 3, and multiple second electrode posts 5 are fixedly connected to the upper surface of the placement rack 1. During testing, multiple cylindrical lithium batteries are vertically placed between the first electrode posts 4 and the second electrode posts 5, with the positive terminals of all lithium batteries facing upwards and the negative terminals facing downwards. The sliding plate 3 descends, causing the first electrode posts 4 to descend as well. The first electrode posts 4 and the second electrode posts 5 clamp the lithium batteries, with the first electrode posts 4 and the second electrode posts 5 facing each other. A first wire 6 is connected between each pair of adjacent first electrode posts 4, and a second wire 7 is connected between each pair of adjacent second electrode posts 5. A wire-wound resistor 8 is fixedly connected to the upper surface of the placement rack 1, with the two ends of the wire-wound resistor 8 connected to the wire-wound resistor 5. Each battery is connected to a third wire 9. The two third wires 9 are connected to the second wire 7 and the first wire 6, respectively. Through the first wire 6, the positive terminals of all lithium batteries are connected to each other, and the negative terminals are connected to each other, forming a parallel lithium battery pack. The third wires 9 are connected in series with the wire-wound resistor 8, and the battery is discharged through the wire-wound resistor 8. Multiple lithium batteries can be discharged at the same time. The discharge process does not produce waste and has a small impact on the environment. When using the battery pack, a low-temperature environment, such as an air-conditioned room, should be selected to facilitate heat dissipation of the lithium batteries. The rack 1 is equipped with a feeding component 10. After a row of lithium batteries has finished discharging, the feeding component 10 removes the discharged lithium batteries from between the first electrode post 4 and the second electrode post 5, and replaces the next batch of lithium batteries for discharge. This eliminates the need for staff to replace the batteries one by one, which helps to speed up the overall discharge speed of the lithium batteries and saves time.

[0025] like Figure 1 As shown, the upper surface of the sliding plate 3 and the lower surface of the placement frame 1 are both fixedly connected to the insulating housing 11. The two third wires 9 pass through the insulating housing 11 respectively. The insulating housing 11 covers the first electrode post 4 and the second electrode post 5 to avoid accidental contact and improve safety.

[0026] like Figure 2 and Figure 3As shown, the feeding assembly 10 includes four support columns 101, which are fixedly connected to the placement frame 1. The four support columns 101 are opposite each other in pairs, and a crossbar 102 is fixedly connected between two opposing support columns 101. Each of the two vertical plates 2 has a square groove on one side. The crossbar 102 passes through the square groove and is fixedly connected to the vertical plate 2. A sliding rod 103 is slidably connected to the two crossbars 102. Multiple horizontal plates 104 are fixedly connected between the two sliding rods 103. Each horizontal plate 104 has multiple arrays of circular through slots. A lithium battery is placed in each circular through slot, with the positive terminal of the lithium battery facing upwards and the negative terminal facing downwards. When discharging, the sliding rod 103 is pushed, causing the horizontal plate 104 to move. When one horizontal plate... When 104 moves below the sliding plate 3, all the negative electrodes of the lithium batteries on the horizontal plate 104 are in contact with the second electrode post 5. At this time, the sliding plate 3 descends, and the first electrode post 4 contacts the positive electrode of the lithium battery, forming a parallel discharge circuit and starting the discharge. The number of circular slots on each horizontal plate 104 is the same as the number of the first electrode post 4 and the second electrode post 5, and their positions are opposite. When the lithium battery on one horizontal plate 104 has finished discharging, the sliding rod 103 continues to move, causing the discharged lithium battery to slide and misalign with the sliding plate 3, so that the lithium battery on the second horizontal plate 104 moves above the second electrode post 5 for discharge. This allows for the complete replacement of the lithium battery, making loading more convenient and faster.

[0027] like Figure 3 and Figure 4 As shown, a rack 12 is fixedly connected to the lower surface of one of the sliding rods 103. A mounting plate 13 is fixedly connected to one side of the vertical plate 2 near the rack 12. A first servo motor is mounted on one side of the mounting plate 13. A gear 14 is fixedly connected to the spindle of the first servo motor. The gear 14 meshes with the rack 12. When replacing the lithium battery, the first servo motor starts and drives the sliding rod 103 to move through the gear 14 and the rack 12 for replacement, making it more convenient to use.

[0028] like Figure 2 As shown, the sliding plate 3 passes through two vertical plates 2. Two support plates 15 are fixedly connected to one side of one of the vertical plates 2. A second servo motor is fixedly connected to one side of one of the support plates 15. The main shaft of the second servo motor is fixedly connected to a threaded rod 16. The threaded rod 16 passes through the sliding plate 3 upward and is threadedly connected to the sliding plate 3. The lifting and lowering of the sliding plate 3 is controlled by the second servo motor driving the threaded rod 16 to rotate. This eliminates the need for staff to approach and operate the sliding plate, making it safer.

[0029] like Figure 1 , Figure 3 and Figure 4As shown, the upper surface of the placement rack 1 is fixedly connected to the fixing plate 17 on one side of the sliding plate 3. The upper surface of the fixing plate 17 is provided with multiple square grooves. The width of the square grooves is the same as the diameter of the second electrode post 5. The fixing plate 17 is provided with multiple circular through holes. The second electrode post 5 is located in the square grooves. The upper surface of the second electrode post 5 and the bottom surface of the square grooves are on the same horizontal plane. Each square groove is opposite to the second electrode post 5. When the horizontal plate 104 slides, the lithium battery slides in the square grooves and moves closer to the second electrode post 5. The square grooves provide a track for the movement of the lithium battery and prevent the lithium battery from shifting.

[0030] like Figure 3 As shown, a square through groove is provided on the upper surface of the placement rack 1 on the other side of the sliding plate 3. The placement box 18 is fixedly connected in the square through groove. An inclined plate 19 is fixedly connected between the two vertical plates 2. The inclined plate 19 is located above the square through groove. The overall height of the inclined plate 19 is higher than that of the horizontal plate 104. When the lithium battery is discharged, the horizontal plate 104 moves, allowing the lithium battery to slide over the sliding plate 3 and continue to slide. When it reaches the upper surface of the placement box 18, the lithium battery falls into the placement box 18 for collection under the action of gravity. If the lithium battery is stuck on the horizontal plate 104 and cannot be detached, when the horizontal plate 104 continues to move, the upper end of the lithium battery contacts the inclined plate 19. Under the pressure of the inclined plate 19, the lithium battery is detached from the horizontal plate 104. By setting the inclined plate 19, the lithium battery can be detached, making it convenient to collect the lithium battery.

[0031] Working principle: Each circular slot contains a lithium battery with the positive terminal facing upwards and the negative terminal facing downwards. The first servo motor starts, driving the sliding rod 103 to move via gear 14 and rack 12. The horizontal plate 104 moves below the sliding plate 3, at which point all the negative terminals of the lithium batteries on the horizontal plate 104 contact the second electrode post 5. The second servo motor then drives the threaded rod 16 to rotate, causing the sliding plate 3 to descend and the first electrode post 4 to descend. The first electrode post 4 and the second electrode post 5 clamp the lithium batteries. At this point, the lithium batteries are connected in parallel and in series with the wire-wound resistor 8, discharging through the wire-wound resistor 8. When the lithium battery on one horizontal plate 104 is discharged, the sliding rod 103 continues to move, causing the discharged lithium battery to slide and misalign with the sliding plate 3, so that the lithium battery on the second horizontal plate 104 moves above the second electrode post 5 to discharge. When the discharged lithium battery reaches the upper surface of the placement box 18, it falls into the placement box 18 for collection under the action of gravity. If the lithium battery is stuck on the horizontal plate 104 and cannot be detached, when the horizontal plate 104 continues to move, the upper end of the lithium battery contacts the inclined plate 19. Under the pressure of the inclined plate 19, the lithium battery is detached from the horizontal plate 104.
