Description

Technical Field

[0001] The present disclosure relates to the technical field of battery monomer recycling, and in particular to a battery monomer discharge device. Background Art

[0002] The rapid development of new energy vehicles has led to an increase in the use of lithium-ion batteries, necessitating the efficient recycling and disposal of used lithium-ion batteries. Currently, mainstream recycling technologies include hydrometallurgy, pyrometallurgy, and physical disassembly. To ensure safety and reliability during the recycling process, the battery cells must be discharged during pre-treatment.

[0003] The discharge methods for used lithium-ion power batteries are divided into chemical solvent immersion method and physical external load method. The chemical solvent immersion method uses the positive and negative metals of the battery as the cathode and anode respectively, and consumes the residual electricity in the battery through the electrolysis process in the solution, so that the chemical solvent immersion method will produce more wastewater. The physical external load method connects the battery to a resistor, so that the electricity in the battery is discharged through heat release. Due to the diversity of used lithium-ion power battery models, a single discharge device cannot be compatible with the diverse battery cells for discharge, the discharge equipment cannot be automatically loaded, and the discharge equipment uses a parallel discharge method, which makes the discharge efficiency of the battery cells low.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this disclosure pertains. The terms used herein in the specification of this disclosure are intended only to describe specific embodiments and are not intended to limit this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0039] like Figure 1 and Figure 2 As shown, the battery monomer discharge device 10 of one embodiment of the present disclosure includes a conveyor line mechanism 100, a discharge tool 200, a feeding mechanism 300 and a loading mechanism 400; the conveyor line mechanism 100 includes a discharge tank assembly 110 and a conveyor belt assembly 120, the discharge tank assembly 110 is arranged on one side of the conveyor belt assembly 120, the discharge tank assembly 110 is provided with a discharge water tank 1101, clean water can be introduced into the discharge water tank 1101 to accelerate heat dissipation, and the conveyor belt assembly 120 is used to move the discharge tool 200; the discharge tool 200 includes a frame structure 210, a conductive plate structure 220 and a heating component 230, the frame structure 210 0 includes a base plate 211, which is placed on the conveyor belt assembly 120. Two battery placement slots 201 are formed between the base plate 211 and the conductive plate structure 220. The conductive plate structure 220 is slidably mounted on the frame structure 210. The battery placement slots 201 are used to accommodate battery cells. A heating component 230 is fixed to the frame structure 210. The terminal of the heating component 230 is electrically connected to the conductive plate structure 220. The conductive plate structure 220 is used to electrically connect to the battery cells. The heating end of the heating component 230 is disposed in the discharge water tank 1101. The heating component 230 is electrically connected to the conductive plate structure 220 and the battery cells to form a circuit.

[0040] Furthermore, the feeding mechanism 300 is arranged on the other side of the conveyor belt assembly 120, and the feeding mechanism 300 is used to move the battery cell to the battery placement slot 201; the loading mechanism 400 is installed above the conveyor line mechanism 100, and the loading mechanism 400 is used to clamp the conductive plate structure 220 and place it on the battery cell to be discharged.

[0041] In this embodiment, when loading battery cells, the conveyor belt assembly 120 moves the frame structure 210 toward one end of the feed mechanism 300. The feed mechanism 400 grips the conductive plate structure 220 and rises to open the battery placement slot 201, placing the battery cell on the feed mechanism 300. The feed mechanism 300 then moves the battery cell into the battery placement slot 201. The feed mechanism 300 then grips the conductive plate structure 220 and descends, bringing it into contact with the battery cell to be discharged. The feed mechanism 400 releases the conductive plate structure 220 and rises back to its original position, while the conveyor belt assembly 120 transports the discharge tooling 200 forward. The conductive plate structure 220 forms a loop with the battery cell and the heating element 230, causing the heating end of the heating element 230 to generate heat within the discharge water tank 1101. The water in the discharge water tank 1101 exchanges heat with the heating element 230, thereby rapidly discharging the battery cell.

[0042] The above-mentioned battery cell discharge device 10 moves the frame structure 210 close to the feeding mechanism 300 through the conveyor belt assembly 120, and the loading mechanism 400 clamps the conductive plate structure 220 and rises to open the battery placement slot 201. The feeding mechanism 300 moves the battery cell to the battery placement slot 201, so that the battery cell is automatically fed and continuously discharged, thereby improving the discharge efficiency of the battery cell; when the loading mechanism 400 clamps the conductive plate structure 220 and rises, the battery placement slot 201 can accommodate battery cells of different sizes, so that the discharge tooling 200 can discharge battery cells of different sizes, thereby improving the compatibility of battery cell discharge.

[0043] like Figure 1 As shown, in one embodiment, there are multiple discharge fixtures 200. In this embodiment, the conveyor belt assembly 120 moves the multiple discharge fixtures 200 sequentially through the feeding mechanism 300. The feeding mechanism 300 sequentially installs battery cells on the corresponding discharge fixtures 200. The conveyor belt assembly 120 then moves the discharge fixtures 200 to discharge the battery cells. This allows the battery cell discharge device 10 to discharge multiple groups of battery cells simultaneously, thereby improving the discharge efficiency of the battery cells.

[0044] In one embodiment, the battery cell discharge device 10 further includes a discharge mechanism and a discharge mechanism. A discharge position is provided at the rear end of the conveyor belt assembly 120. The discharge mechanism is mounted at the discharge position of the conveyor belt assembly 120. The discharge mechanism is used to clamp the lifting conductive plate structure 220, and the discharge mechanism is used to remove the battery cells from the battery placement slot 201. In this embodiment, the discharge mechanism is provided with a discharge detection component that contacts the conductive plate structure 220. When the discharge mechanism clamps the conductive plate structure 220, the discharge detection component measures whether there is voltage to determine whether the battery has been discharged. If the battery cell has not been discharged, the discharge mechanism releases the conductive plate structure 220, and the battery cell continues to discharge along the conveyor belt assembly 120 along with the discharge mechanism 200. If the battery cell is discharged, the discharge mechanism clamps the conductive plate structure 220 and rises to open the battery placement slot 201. The discharge mechanism removes the battery cell from the battery placement slot 201. This allows for the automatic discharge of discharged battery cells, reduces manual operation, and thereby improves the discharge efficiency of the battery cells.

[0045] In one embodiment, the battery cell discharge device 10 further includes an adaptive system, the sensing end of which is disposed in the discharge water tank 1101 and electrically connected to the control end of the conveyor belt assembly 120. In this embodiment, when a battery cell is installed in the discharge fixture 200 and discharged, the heat generated during the discharge process is absorbed by the water in the discharge water tank 1101, causing the water temperature in the discharge water tank 1101 to rise. The adaptive sensing end system detects the water temperature in the discharge water tank 1101, and the adaptive system then controls the conveying speed of the conveyor belt assembly 120 to control the water temperature. Once the water temperature reaches the desired temperature, the hot water can be pumped out for secondary use via a circulating water pump provided in the adaptive system, thereby improving energy efficiency.

[0046] like Figure 1 As shown, in one embodiment, the feeding mechanism 300 includes a feeding belt assembly 310 and a battery moving assembly 320, the discharge end of the feeding belt assembly 310 is arranged on the other side of the conveyor belt assembly 120, the battery moving assembly 320 includes a support frame 321, a telescopic assembly 322 and an adsorption opening and closing assembly 323, the support frame 321 is installed on the discharge end of the feeding belt assembly 310, the telescopic assembly 322 includes a telescopic cylinder 3221 and a mounting plate 3222, the telescopic cylinder 3221 is installed on the support frame 321, the mounting plate 3222 is connected to the output end of the telescopic cylinder 3221, the adsorption opening and closing assembly 323 is connected to the mounting plate 3222, and the telescopic cylinder 3221 is used to drive the adsorption opening and closing assembly 323 to move back and forth between the battery placement slot 201 and the feeding belt assembly 310. In this embodiment, the battery cells to be discharged are moved to the discharge end of the feed belt assembly 310, the adsorption opening and closing assembly 323 adsorbs the two battery cells, and the telescopic cylinder 3221 accurately controls the extension of the telescopic end, so that the mounting plate 3222 and the adsorption opening and closing assembly 323 drive the battery cells to move from the discharge end of the feed belt assembly 310, so that the battery cells are accurately moved to the two battery placement slots 201, thereby allowing the battery cells to be smoothly transferred to the discharge tooling 200.

[0047] like Figure 3 and Figure 4 As shown, in one embodiment, the battery moving assembly 320 further includes a sensor assembly 324, which is mounted at the discharge end of the feed belt assembly 310, and the sensor assembly 321 is electrically connected to the control terminal of the feed belt assembly 310. In this embodiment, the sensor assembly 321 can sense the position of the battery cells. When two battery cells are moved to the discharge end through the feed belt assembly 310, the sensor assembly 321 transmits signals to the control terminal of the feed belt assembly 310. The control terminal controls the feed belt assembly 310 to stop, so that the battery cells moved by the adsorption opening and closing assembly 323 remain in a fixed position, thereby accurately moving the battery cells to the discharge tooling 200 to complete automatic loading.

[0048] In one embodiment, the suction opening and closing assembly 323 includes a clamping arm 3231 and a suction cup 3232. Both the clamping arms 3231 and the suction cups 3232 are two, with the two clamping arms 3231 spaced apart. The upper ends of the clamping arms 3231 are slidably connected to the mounting plate 3222, and the two suction cups 3232 are respectively fixed to the lower ends of the two clamping arms 3231. In this embodiment, the two suction cups 3232 are each connected to a suction cylinder, which controls the suction cups 3232 to securely hold the corresponding battery cells. The two clamping arms 3231 are spaced apart at different distances, allowing for the placement of battery cells of various sizes between the two clamping arms 3231. The use of the two suction cups 3232 to secure battery cells of varying sizes reduces the need for consistent appearance of the battery cells.

[0049] like Figure 3 and Figure 4 As shown, in one embodiment, the adsorption opening and closing component 323 also includes a servo motor 3233, a gear 3234, a slide rail 3235, a rack 3236 and a slider 3237. The number of racks 3236, the number of slide rails 3235 and the number of sliders 3237 are all two. The servo motor 3233 is installed on the mounting plate 3222, the gear 3234 is installed on the output end of the servo motor 3233, the slide rail 3235 is fixed to the mounting plate 3222, and the two slide rails 3235 are respectively located above and below the gear 3234. One side of the slider 3237 is fixed to the upper end of the corresponding clamping arm 3231, and the other side of the slider 3237 is slidably connected to the corresponding slide rail 3235. One end of the rack 3236 is fixedly connected to the corresponding slider 3237, and the other end of the rack 3236 is engaged with the gear 3234. In this embodiment, when the battery cell moves to the discharge end of the feed belt assembly 310, the servo motor 3233 controls the gear 3234 to drive the two racks 3236 to move, and the two racks 3236 respectively drive the corresponding clamping arms 3231 to slide on the slide rail 3235 to clamp the battery cell. The servo motor 3233 controls the gear 3234 to rotate and drive the two clamping arms 3231 to separate the battery cells adsorbed by the two suction cups 3232, so that the battery cells are accurately placed in two battery placement slots 201 that are spaced apart.

[0050] Furthermore, the suction opening and closing assembly 323 also includes two guide sliding blocks 3238, one side of which is connected to the clamping arm, and the other side of which is connected to the corresponding clamping arm 3231. The slider 3237 and the guide sliding block 3238 on each clamping arm 3231 are slidably connected to different slide rails 3235. In this embodiment, each clamping arm 3231 is slidably connected to a different slide rail 3235 via the slider 3237 and the guide sliding block 3238, so that the slider 3237 and the guide sliding block 3238 simultaneously guide the movement direction of the clamping arm, thereby making the sliding of the clamping arm 3231 more stable.

[0051] like Figure 5 As shown, in one embodiment, the frame structure 210 includes an upper plate 212 and a guide shaft 213. One end of the guide shaft 213 is connected to the bottom plate 211, and the other end of the guide shaft 213 is connected to the upper plate 212. The conductive plate structure 220 is slidably disposed on the guide shaft 213. In this embodiment, the upper plate 212 is made of an insulating material, so that the upper plate 212 and the heating component 230 are insulated. The conductive plate structure 220 is slidably disposed on the guide shaft 213, so that the battery placement slot 201 can be adapted to accommodate battery cells of different sizes, thereby improving the compatibility of the discharge tooling 200 with battery cells of different sizes.

[0052] like Figure 5 and Figure 6 As shown, in one embodiment, the conductive plate structure 220 includes a tie rod 221, a middle separator 222, and a conductive connection assembly 223. The tie rod 221 passes through the upper plate 212 and is connected to the middle separator 222. The tie rod 221 is slidably connected to the upper plate 212, and the middle separator is slidably connected to the guide shaft 213. The conductive connection assembly 223 includes a conductive block 2231, which is disposed below the middle separator 222. The conductive block 2231 is electrically connected to the heating element 230 and is used to electrically connect to the battery cell. In this embodiment, the middle separator 222 is made of an insulating material to provide insulation between the conductive plate structure 220 and the tie rod 221.

[0053] like Figure 5 and Figure 6As shown, in one embodiment, the frame structure 210 also includes a first linear bearing 214 and a second linear bearing 215, the upper plate 212 is provided with a first through hole 2101, the middle partition 222 is provided with a second through hole 2102, the guide shaft 213 is movably passed through the second through hole 2102, the conductive connection component 223 is connected to the middle partition 222, the first linear bearing 214 is installed in the first through hole 2101, the pull rod 221 is movably passed through the first through hole 2101, and a limit block 2211 is protruding from the middle of the pull rod 221, the second linear bearing 215 is installed in the second through hole 2102, the middle partition 222 is provided with a second through hole 2102, and the guide shaft 213 is movably passed through the second through hole 2102. In this embodiment, the limit block 2211 can limit the descending height of the pull rod 221, so that the pull rod 221 is maintained at a certain height, thereby facilitating the loading mechanism 400 to clamp the lifting pull rod 221. The first linear bearing 214 is sleeved on the pull rod 221, reducing the friction between the pull rod 221 and the upper plate 212. The second linear bearing 215 is sleeved on the guide shaft 213, reducing the friction between the guide shaft 213 and the middle partition 222, thereby making the pull rod 221 and the middle partition 222 move more smoothly.

[0054] like Figure 5 and Figure 6 As shown, in one embodiment, the electric plate structure 220 further includes a series conductor 224, and the number of conductive blocks 2231 is four. The conductive blocks 2231 are all connected to the middle partition 222. Two conductive blocks 2231 are correspondingly provided above each battery placement slot 201. The two ends of the series conductor 224 are respectively connected to the two conductive blocks 2231 away from the heating component 230, and the two terminal ends of the heating component 230 are connected to the two conductive blocks adjacent to the heating component 230. In this embodiment, two conductive blocks 2231 are correspondingly provided above the two battery placement slots 201, which can be respectively connected to the positive and negative poles of the battery cells. The two battery cells are connected in series through the two conductive blocks 2231 connected by the series conductor 224, and then connected in series with the heating component 230 through the two conductive blocks 2231 adjacent to the heating component 230 to form a loop. After the two battery cells are connected in series, they are discharged simultaneously through the heating component 230, thereby improving the discharge speed of the battery.

[0055] Furthermore, in the traditional parallel discharge of multiple batteries, due to the differences in the heights of the recovered single batteries, some single batteries discharged in parallel may not be able to contact the conductive plate structure, thereby affecting the qualified rate of battery single battery discharge. Compared with the traditional parallel discharge of multiple battery cells, the series wire 224 connects the two conductive connection components 223, so that the two battery cells are connected in series to form a loop with the heating component 230, so that the two battery cells are discharged at the same time and the voltage is increased, thereby making the heating component 230 more efficient in discharging the battery cells, and at the same time ensuring the qualified rate of battery single battery discharge; in the traditional parallel discharge of multiple battery cells, there are energy differences between the multiple battery cells, so that some battery cells have been discharged while other battery cells are still discharging, which can easily lead to over-discharge of the discharged battery cells and cause fire and explosion. Compared with the traditional parallel discharge of multiple battery cells, the safety of battery single battery discharge is improved by connecting two battery cells in series with the heating component 230 to form a loop.

[0056] like Figure 5 As shown, in one embodiment, the conductive connection assembly 223 further includes a bolt 2232 and a spring 2233. The conductive block 2231 defines a through-hole 2201. The bolt 2232 is inserted through the through-hole 2201. The lower end of the bolt 2232 is fixedly connected to the conductive block 2231. The upper end of the bolt 2232 passes through the middle partition 222 and is engaged with the upper surface of the middle partition 222. The bolt 2232 is slidably connected to the middle partition 222. The spring 2233 is sleeved on the bolt 2232. One end of the spring 2233 abuts the conductive block 2231, and the other end abuts the middle partition 222. In this embodiment, when the battery cell is discharging, the weight of the conductive plate structure 220 compresses the spring 2233, causing the conductive block 2231 of the conductive plate structure 220 to elastically abut the battery cell, thereby maintaining contact between the conductive block 2231 and the battery cell, thereby preventing discharge-induced false contact when the frame structure 210 is moved.

[0057] like Figure 5 As shown, in one embodiment, the bottom plate 211 is provided with two limiting grooves 2103. In this embodiment, when a battery cell is placed in the battery placement slot 201, the limiting grooves 2103 can limit the bottom of the battery cell, ensuring accurate placement of the battery cell, thereby further ensuring that the positive and negative terminals of the battery cell are connected to the conductive block 2231 at a more accurate position.

[0058] like Figure 5 and Figure 7As shown, in one embodiment, the heating assembly 230 includes a connecting plate 231, a heating tube 232, and two conductive contact plates 233. One end of the connecting plate 231 is connected to the frame structure 210, and the two conductive contact plates 233 are mounted on the connecting plate 231. The conductive contact plates 233 are located below the feeding mechanism 400. The heating tube 232 and the conductive block 2231 are both electrically connected to the two conductive contact plates 233. In this embodiment, the two conductive contact plates 233 are in contact with the feeding mechanism 400, allowing the feeding mechanism 400 to detect whether the two conductive contact plates 233 are connected to the heating tube 232 to form a circuit. The connecting plate 231 positions the heating end of the heating tube 232 above the discharge tank 1101. The connecting plate 231 prevents contact between the conductive contact plates 233 and the frame structure 210, thereby maintaining insulation between the conductive contact plates 233 and the frame structure 210.

[0059] like Figure 2 and Figure 7 As shown, in one embodiment, the loading mechanism 400 includes a lifting bracket 410, a lifting cylinder 420, a clamping cylinder 430 and a voltage detection component 440. The lifting bracket 410 is installed on the conveyor belt component 120, the lifting cylinder 420 is installed on the lifting bracket 410, the clamping cylinder 430 is connected to one side of the telescopic end of the lifting cylinder 420, and the clamping cylinder 430 is located above the conductive plate structure 220. The voltage detection component 440 is connected to the other side of the telescopic end of the lifting cylinder 420, and the voltage detection component 440 is located above the heating component 230. In this embodiment, the lifting cylinder 420 controls the clamping cylinder 430 to lift the conductive plate structure 220 and open the battery placement slot. Once a battery cell is placed, the lifting cylinder 420 controls the clamping cylinder 430 to lower the conductive plate structure 220, causing the voltage detection assembly 440 to descend and contact the conductive contact plate 233 in the heating assembly 230. This allows the voltage detection assembly 440 to form a circuit between the discharge fixture 200 and the heating assembly 230 to perform voltage detection on the battery cell discharge, thereby determining whether the discharge device is discharging normally and whether the battery cell discharge is complete. The clamping cylinder 430 releases the conductive plate structure 220, the battery moving assembly 320 moves the moving battery cell, and the conveyor belt assembly 120 drives the discharge fixture 200 to move, thereby successfully completing the automatic placement of the battery cell into the discharge fixture 200 for discharge.

[0060] like Figure 7As shown, in one embodiment, the conveyor line mechanism 100 further includes a blocking cylinder assembly 130, which is mounted on the conveyor belt assembly 120. The blocking cylinder assembly 130 is used to block the movement of the discharge tooling 200. The blocking cylinder assembly 130 can be a limiter. In this embodiment, when the discharge tooling 200 moves close to the discharge end of the feed belt assembly 310, the blocking cylinder assembly 130 blocks the movement of the discharge tooling 200, causing the discharge tooling 200 to remain in a fixed position, thereby allowing the battery moving assembly 320 to accurately move the battery cells to the battery placement slot 201.

[0061] Compared with the prior art, the present disclosure has at least the following advantages:

[0062] 1. The battery cell discharge device 10 described above uses the conveyor belt assembly 120 to move the frame structure 210 toward the feeding mechanism 300. The loading mechanism 400 clamps the conductive plate structure 220 and rises to open the battery placement slot 201. The feeding mechanism 300 moves the battery cell into the battery placement slot 201, allowing the battery cell to be automatically fed and continuously discharged, thereby improving the discharge efficiency of the battery cell.

[0063] 2. When the loading mechanism 400 holds the conductive plate structure 220 and rises, the battery placement slot 201 can place battery cells of different sizes, so that the discharge tooling 200 can discharge battery cells of different sizes, thereby improving the compatibility of battery cell discharge.

[0064] 3. The conductive plate structure 220 can connect the battery cells in the two battery placement slots 201 in series to generate a higher voltage, so that the battery cells form a loop with the heating component 230 for discharge after being connected in series, thereby improving the discharge efficiency of the battery cells.

[0065] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the scope of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the disclosed patent shall be determined by the appended claims.
