[0002] With the increasing popularity of electric vehicles and other products using lithium battery technology, the recycling of lithium batteries has become increasingly important. Existing lithium battery disassembly and recycling processes generally undergo pre-processing before entering the actual disassembly process, including discharge treatment to reduce risks and battery classification. For large-capacity battery packs in electric vehicles, it may be necessary to first remove the outer shell, separate the battery modules, and then mechanically crush them for further processing. However, existing devices generally use a single crushing and disassembly equipment, and the accumulated lithium batteries need to wait for a period of time. In addition, during the transportation process, there is a lack of real-time visual inspection, making it difficult to judge the real-time status of the lithium batteries, resulting in a reduction in the final efficiency.

[0003] Therefore, in response to the above problems, a lithium battery disassembly and recycling device with automatic classification is now developed. Summary of the invention

[0006] In one embodiment, the diversion mechanism includes a fixed frame, which is installed on the upper side of the middle of the collection frame. The top of the fixed frame is a disc structure. A first drive motor is installed on the rear side of the disc structure on the upper part of the fixed frame. The output shaft of the first drive motor is set to face forward. Two front-to-back symmetrical visual components are installed on the inner side of the upper part of the fixed frame. The visual components are used to detect the specification status of the lithium battery. Four rotating rollers are rotatably connected to the upper part of the fixed frame, one of which is connected to the output shaft of the first drive motor. A transmission belt for conveying the diverted lithium batteries is wound between the rotating rollers, and a pulley assembly is connected between the rotating rollers.

[0007] In one embodiment, the stabilizing mechanism includes an air storage assembly, the air storage assembly is installed on the right side of the collection frame, two air intake frames are connected between the air storage assembly and the collection frame, the air intake frames are connected and communicated with the collection frame, and a refrigeration assembly is installed on the right side of the collection frame.

[0008] In one of the embodiments, a toggle mechanism is also included, and the toggle mechanism includes a second drive motor. The second drive motor is installed on the rear side of the lower part of the collection frame, and the output shaft of the second drive motor is set to face forward. A toggle frame for toggling lithium battery fragments is slidably connected in the collection frame, and the toggle frame is a "X"-shaped structure. A screw rod is installed on the output shaft of the second drive motor, and the screw rod is rotatably connected to the collection frame.

[0009] In one of the embodiments, a discharging mechanism is also included, and the discharging mechanism includes a rotating plate. The front side of the collection frame is rotatably connected to two rotating plates that are symmetrical on the left and right. Two latches are slidably connected to the rotating plates, and the latches are both engaged with the collection frame. Springs are connected between the latches and adjacent rotating plates, and the springs are mounted on the corresponding latches.

At the same time, the refrigeration component will quickly cool down to avoid other unexpected problems caused by excessive temperature.

[0016] 3. After the lithium battery is crushed, in order to ensure sufficient separation of solid and liquid, the second drive motor can be started synchronously.

DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0029] Example 1

[0030] An automatic classification lithium battery disassembly and recycling device, such as Figure 1 and Figure 2 As shown, it includes a collecting frame 1, and two liquid outlets 2 are arranged on the front side of the lower part of the collecting frame 1. Trapezoidal blocks 3 are connected to the left and right sides of the lower part of the collecting frame 1, and the trapezoidal blocks 3 are used to limit and guide the battery liquid after crushing. Disassembly components 4 are connected to the left and right sides of the collecting frame 1, and the disassembly components 4 are used to quickly crush and disassemble the lithium battery. The left and right parts of the collecting frame 1 are connected to sieve plates 5, and the sieve plates 5 are used to block the solid fragments of the crushed lithium battery to achieve solid-liquid classification processing, and also include: a diversion mechanism 6, the diversion mechanism 6 is arranged on the collecting frame 1, and is used for automatic identification of the lithium battery to be processed. The diversion and guiding processing; the stabilization mechanism 7, the stabilization mechanism 7 is arranged on the left and right sides of the collecting frame 1, and is used to generate inert gas, block external air and cool and protect the crushed lithium battery.

[0031] It should be noted that when recycling lithium batteries, the device can be used to disassemble and crush the lithium batteries. First, the lithium batteries are placed on the diversion mechanism 6, and then the diversion mechanism 6 is started. According to the specifications of the lithium batteries, they are sent to the disassembly component 4. After the lithium batteries are sent into the disassembly component 4, the disassembly component 4 will disassemble and crush the lithium batteries. The crushed lithium batteries will fall on the sieve plate 5, and rely on the filtering and barrier effect of the sieve plate 5 to perform solid-liquid separation. At the same time, the stabilization mechanism 7 is started to allow the inert gas to cover the lower part of the collection frame 1 to prevent external air from entering the collection frame 1 and causing unnecessary accidents. At the same time, the inert gas can also cool the crushed lithium battery waste to achieve a cooling effect.

[0032] like Figure 1 , Figure 3 and Figure 4 As shown, the diversion mechanism 6 includes a fixed frame 61, which is installed on the upper middle side of the collecting frame 1. The top of the fixed frame 61 is a disc structure. A first drive motor 62 is installed on the rear side of the upper disc structure of the fixed frame 61. The output shaft of the first drive motor 62 is set to face forward. Two front-to-back symmetrical visual components 63 are installed on the inner side of the upper part of the fixed frame 61. The visual component 63 is used to detect the specification status of the lithium battery. Four rotating rollers 64 are rotatably connected to the upper part of the fixed frame 61, one of which is connected to the output shaft of the first drive motor 62. A transmission belt for conveying the diverted lithium battery is wound between the rotating rollers 64. A pulley assembly 66 is connected between the rotating rollers 64. The pulley assembly 66 consists of a pulley and a transmission belt. The pulleys are correspondingly installed on the rotating rollers 64, and the transmission belt is wound between the corresponding pulleys.

[0033] It should be noted that the lithium battery is first placed on the conveyor belt 65, and then the visual component 63 and the first drive motor 62 are started. At this time, the visual component 63 will perform diversion processing on the lithium battery in the corresponding direction according to the specifications and status of the lithium battery and the situation of the disassembly component 4. First, the rotation of the output shaft of the first drive motor 62 will drive the corresponding rotating roller 64 to rotate, so that the pulley component 66 drives the remaining rotating rollers 64 to rotate, and then the conveyor belt 65 transports the lithium battery. When some lithium batteries enter the disassembly component 4, the visual component 63 detects that the number of lithium batteries has changed significantly, and will control the output shaft of the first drive motor 62 to rotate in the opposite direction, so that the conveyor belt 65 runs in the opposite direction and sends the lithium battery into the disassembly component 4 on the other side, realizing intelligent diversion processing and avoiding centralized processing of lithium batteries, which affects processing efficiency.

[0034] like Figure 1 and Figure 5As shown, the stabilizing mechanism 7 includes an air storage assembly 71, and the air storage assembly 71 is installed on the right side of the collection frame 1. Two air intake frames 72 are connected between the air storage assembly 71 and the collection frame 1. The air intake frames 72 are connected and communicated with the collection frame 1, and a refrigeration assembly 73 is installed on the right side of the collection frame 1.

[0035] It should be noted that when disassembling and crushing lithium batteries, it is necessary to start the gas storage component 71 and the refrigeration component 73 simultaneously so that the inert gas can cover the lower part of the collection frame 1 to block the external air and avoid the lithium battery from exploding. At the same time, the refrigeration component 73 will quickly cool down to avoid other unexpected problems caused by excessive temperature.

[0036] Example 2

[0037] On the basis of Example 1, Figure 1 and Figure 6 As shown, as shown, it also includes a toggle mechanism 8, which includes a second drive motor 81. The second drive motor 81 is installed on the rear side of the lower part of the collection frame 1, and the output shaft of the second drive motor 81 is set to face forward. A toggle frame 82 for toggling lithium battery fragments is slidably connected in the collection frame 1. The toggle frame 82 is a "X"-shaped structure, and a screw rod 83 is installed on the output shaft of the second drive motor 81. The screw rod 83 is rotatably connected to the collection frame 1.

[0038] It should be noted that after the lithium battery is crushed, in order to ensure sufficient separation of solid and liquid, the second drive motor 81 can be started synchronously. The rotation of the output shaft of the second drive motor 81 will drive the screw 83 to rotate, so that the toggle frame 82 can reciprocate back and forth along the collection frame 1. In the process of the toggle frame 82 reciprocating back and forth, the lithium battery fragments accumulated on the sieve plate 5 will be tossed, thereby preventing the fragments from clogging the sieve plate 5, resulting in the battery liquid being unable to flow downward and separate.

[0039] like Figure 1 and Figure 7 As shown, it also includes a discharging mechanism 9, which includes a rotating plate 91. The front side of the collection frame 1 is rotatably connected to two symmetrical rotating plates 91. Two latches 92 are slidably connected to the rotating plates 91. The latches 92 are both engaged with the collection frame 1. Springs 93 are connected between the latches 92 and adjacent rotating plates 91. The springs 93 are all mounted on the corresponding latches 92. The rear part of the collection frame 1 is slidably connected to two symmetrical pushing frames 94. The pushing frames 94 are used to push the latches 92.

[0040] It should be noted that after the lithium battery processing is completed, the pushing frame 94 is pushed forward. During the forward movement, the pushing frame 94 will push the lithium battery fragments forward, so that the lithium battery fragments can be concentrated and moved to the front side of the collection frame 1. When the pushing frame 94 moves to the extreme position, the pushing frame 94 will push the pin 92, so that the pin 92 is disengaged from the collection frame 1. At this time, the rotating plate 91 will automatically flip downward and open, making it easy for the operator to take out the lithium battery fragments.

[0041] like Figure 1 , Figure 8 and Fig. 9 As shown, it also includes a driving mechanism 10, which includes a clamping wheel 101. The clamping wheels 101 are rotatably connected to the left and right sides of the upper part of the toggle frame 82. The clamping wheels 101 are each provided with a clamping groove, which can be clamped with the corresponding pushing frame 94. The rear side of the clamping wheel 101 is connected to a rotating handle 102.

[0042] It should be noted that in order to improve convenience and reduce manual operation steps, when it is necessary to control the movement of the pushing frame 94, the rotating handle 102 can be controlled to rotate the clamping wheel 101, so that the clamping groove on the clamping wheel 101 is clamped with the pushing frame 94. At this time, the second drive motor 81 is directly started to drive the toggle frame 82 to move, so that the pushing frame 94 can move forward automatically.

[0043] like Figure 1 and Fig.10 As shown, it also includes a feeding mechanism 11, which includes a feeding frame 111. The feeding frame 111 is arranged between the left and right sides of the fixed frame 61 by bolts, and two inclined plates 112 are installed in the feeding frame 111. The inclined plates 112 are used to buffer and guide the lithium battery feeding.

[0044] It should be noted that when feeding lithium batteries, the lithium batteries are put into the feeding frame 111 in batches. Under the guidance of the inclined plate 112, the lithium batteries can be fed slowly and orderly to avoid abnormalities caused by excessive feeding at one time.

[0045] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
