Description

Technical Field

[0002] Lithium battery recycling refers to the process of recycling and treating waste lithium batteries. Recycling lithium batteries is of great significance. Valuable materials such as lithium, cobalt, and nickel can be recycled. It can reduce pollution to the environment and prevent harmful substances in waste batteries from damaging soil and water. When recycling waste lithium batteries, they need to be crushed and sorted. For example, a crushing and sorting device for recycling waste lithium batteries proposed in the authorization publication number CN113399038B does not require manual crushing and sorting of waste lithium batteries, which is more labor-saving and convenient.

The spacing of the cutters inside the crushing device is relatively fixed, and the sizes of different types of lithium batteries are different. When the lithium battery to be crushed is large in size and the spacing of the cutters is small, the cutters are prone to over-crushing when crushing the lithium battery. Excessive crushing may cause some valuable materials to become too small and difficult to effectively recycle and utilize; and when the lithium battery is small in size and the spacing of the cutters is too large, the lithium battery cannot be effectively crushed, resulting in some batteries still remaining in large blocks, affecting subsequent processing and material recovery effects.

Before placing the waste lithium batteries in the crushing device for crushing, the waste lithium batteries can be automatically detected for the amount of electricity inside the waste lithium batteries. When it is detected that there is still electricity left in the waste lithium batteries, the waste lithium batteries are conveyed to one side for subsequent discharge treatment, thereby avoiding the problem that the operator forgets to pre-discharge the waste lithium batteries, resulting in the waste lithium batteries catching fire due to short circuit during the crushing process.

[0024] The front and rear inner walls of the conveying frame 302 are both fixedly connected with guide plates 46 . The two guide plates 46 are both inclined to guide the moving direction of the waste lithium batteries.

[0025] The operating principle of the present invention is now explained as follows: the waste lithium batteries to be crushed are placed in the storage cylinder 7. The rear side of the storage cylinder 7 can be opened, which is convenient for the operator to stack the lithium batteries and avoids the situation where the lithium batteries fall and cause internal short circuits. When the lithium batteries need to be crushed, the operator sends a control signal to the PLC controller 2 through the operation interface. After receiving the control signal, the PLC controller 2 first controls the first electric push rod 9 and the first conveyor belt 5 to work simultaneously. The first electric push rod 9 pushes the lithium battery at the bottom through the discharge port 11 through the push block 10, so that the lithium battery falls onto the surface of the first conveyor belt 5. Then the PLC controller 2 controls the first electric push rod 9 to drive the push block 10 to retract, so that the lithium battery above The battery falls onto the surface of the support plate 6, and the upper surface of the push block 10 is an inclined surface, so that the upper lithium battery can slowly fall onto the support plate 6, and the lithium battery is transported to the left by the first conveyor belt 5. When the lithium battery is transported to the proximity switch 4, it will be detected by the proximity switch 4. When the proximity switch 4 detects the approach of the lithium battery, the proximity switch 4 will send an electrical signal to the PLC controller 2. After receiving the electrical signal, the PLC controller 2 will control the first conveyor belt 5 to stop working, and then the PLC controller 2 will control the second electric push rod 13 to work, so that the second electric push rod 13 drives the clamping box 15 to move downward, so that the clamping box 15 drives the two clamping seats 20 to be located on the front and rear sides of the lithium battery, and then the PLC controller 2 controls The servo motor 17 is driven to work, and the servo motor 17 drives the first threaded rod 16 to rotate, and drives the two first threaded cylinders 18 to move in the direction of approaching each other through threaded cooperation. The two first threaded cylinders 18 drive the two clamping seats 20 to move in the direction of approaching each other through two guide plates 19, and the clamping seats 20 are used to clamp the lithium battery in the direction close to the left (by setting the position between the proximity switch 4 and the clamping box 15, the clamping seat 20 can make contact with the position close to the left side of the lithium battery). When the two clamping seats 20 clamp the lithium battery, an interaction force is generated between the clamping seats 20 and the lithium battery. A pressure sensor 21 is provided on the front side wall of the rear clamping seat 20. When the pressure sensor 21 detects that the clamping force between the clamping seat 20 and the lithium battery reaches the set After a certain force is applied, the pressure sensor 21 will transmit an electrical signal to the PLC controller 2. After receiving the electrical signal, the PLC controller 2 will control the servo motor 17 to stop working immediately, and then control the second electric push rod 13 to retract, thereby driving the lithium battery to move upward to the set position, and the clamping seat 20 is in contact with the position near the left side of the lithium battery. When the clamping seat 20 drives the lithium battery to move upward, the lithium battery will rotate clockwise along the clamping seat 20, so that the electrodes of the lithium battery are placed upward, and then the PLC controller 2 controls the small electric push rod 42 to drive the two conductive plates 44 to move downward through the lifting plate 43, so that the conductive plates 44 are in contact with the two electrodes, and the two conductive plates 44 are electrically connected to the PLC controller 2. When there is residual electricity in the lithium battery,When the two conductive plates 44 are in contact with the positive and negative electrodes, the PLC controller 2 will sense the residual power inside the lithium battery through the ammeter (the PLC controller 2 is electrically connected to the two conductive plates 44 through the ammeter), and the PLC controller 2 will drive the lithium battery to move above the second conveyor belt 45 through the linear motor 122, and place the lithium battery on the second conveyor belt 45 to be transported to another place for storage. When the PLC controller 2 does not detect that there is residual power inside the lithium battery, the PLC controller 2 will control the conductive frame 24 to be energized, so that the conductive frame 24 is electrically connected to the external power supply; Driven by the two first threaded cylinders 18, the conductive frame 24 and the resistor plate 23 will move toward each other, so that the conductive frame 24 and the resistor plate 23 slide against each other, and the larger the size of the lithium battery, the closer the conductive frame 24 and the resistor plate 23 will be to the right end. The right end of the resistor plate 23 is electrically connected to the electromagnetic block 34, and the external current will be transmitted to the electromagnetic block 34 through the resistor plate 23. At this time, the conductive frame 24 and the resistor plate 23 are in contact near the right end, and the external current will be transmitted to the electromagnetic block 34 through the resistor plate 23, so that the electromagnetic block 34 is energized to generate magnetic force, and at this time, because the size of the lithium battery is large, the conductive frame 24 and the resistor plate 23 are close to the right end. The metal block 47 is in electrical contact with the external power supply, thereby reducing the resistance on the circuit connected to the electromagnetic block 34. When the external voltage remains unchanged, the current delivered to the circuit of the electromagnetic block 34 becomes larger. The greater the magnetic force generated by the electromagnetic block 34, the electromagnetic block 34 will attract the permanent magnetic plate 37, so that the permanent magnetic plate 37 drives the square plate 35 to move forward, and the square plate 35 drives the metal plate 36 to move forward to the set position. Then the PLC controller 2 controls the metal block 47 to be electrically connected to the external power supply. At this time, the metal block 47 and the metal plate 36 are in contact, and the external current will be delivered to the positive circuit of the regulating motor 28 through the metal plate 36, so that the regulating motor 28 starts to work, and the regulating motor 28 drives the two sides through the pulley transmission assembly. The second threaded rod 27 rotates, and the second threaded cylinder 29 is driven to move through the threaded fit, and the two second threaded cylinders 29 on the same side will move away from each other, thereby driving the two cutting rollers 31 to move away from each other, and expanding the distance between the two cutting rollers 31, until the second threaded cylinder 29 drives the metal block 47 and the metal plate 36 to separate, and then the forward circuit of the regulating motor 28 is disconnected, so that the regulating motor 28 stops working (when a waste lithium battery is crushed, the PLC controller 2 will control the regulating motor 28 to work in the reverse direction for the same time, so that the two cutting rollers 31 return to the initial distance). When the regulating motor 28 stops working, the PLC controller The controller 2 will control the linear motor 122 to drive the lithium battery to move to the top of the crushing cylinder 252, and then the PLC controller 2 will control the servo motor 17 to rotate in the opposite direction, and control the two clamping seats 20 to move in opposite directions, so that the lithium battery will fall into the crushing cylinder 252, and then the PLC controller 2 will control the two cutting motors 32 to work, and the cutting motors 32 will drive the two cutting rollers 31 to rotate, and the cutting rollers 31 will be used to crush the lithium battery. The spacing of the cutting rollers 31 is adjusted according to the size of the lithium battery, which ensures that the waste lithium battery is fully decomposed, and also avoids the problem that the lithium battery is over-crushed, which will make the material too small and difficult to be effectively recycled and utilized; When the cutting roller 31 starts to crush, the PLC controller 2 will control the electromagnetic seat 382 and the vibration motor 39 to energize and work, and the material crushed by the cutting roller 31 will fall onto the surface of the vibration guide rack 381, and the material with magnetic material will be adsorbed on the surface of the vibration guide rack 381 by the magnetic attraction generated by the electromagnetic seat 382, ​​and the material without magnetic material will fall along the vibration guide rack 381 into the recovery box 41 on one side. Tap water is placed in the recovery box 41, so that the material with lower density floats on the water surface and the material with higher density sinks to the bottom of the water. When the crushing component 25 After the work is completed, the PLC controller 2 will control the recovery motor 401 to rotate 180 degrees, and place another recovery box 41 under the vibrating material guide rack 381. Then the PLC controller 2 controls the electromagnetic seat 382 to lose its magnetic force, and the magnetic material on the surface of the vibrating material guide rack 381 will fall into the recovery box 41. Ten seconds after the electromagnetic seat 382 loses power, the PLC controller 2 will control the recovery motor 401 to continue to rotate 180 degrees, so that the recovery box 41 containing tap water continues to be placed on the left side of the vibrating material guide rack 381 to recycle the next material.
