Description

Technical Field

[0001] This invention relates to the field of lithium battery recycling technology, and in particular to an automatic sorting lithium battery dismantling and recycling device. Background Technology

[0002] With the increasing popularity of electric vehicles and other products using lithium battery technology, lithium battery recycling has become increasingly important. Existing lithium battery dismantling and recycling processes typically involve pre-treatment before entering the actual dismantling process. This includes discharge treatment to reduce risks and battery sorting. For large-capacity battery packs in electric vehicles, it may be necessary to first remove the casing, then separate the battery modules, and then mechanically crush them for further processing. However, existing devices generally use a single crushing and dismantling equipment. The accumulated lithium batteries need to wait for a period of time, and 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 final reduction in efficiency.

[0003] Therefore, in order to address the above problems, an automatic sorting lithium battery dismantling and recycling device is now being developed. Summary of the Invention

[0004] To overcome the shortcomings of existing devices that generally use a single crushing and dismantling equipment, require a period of waiting for accumulated lithium batteries, and lack real-time visual inspection during transportation, making it difficult to judge the real-time status of lithium batteries and ultimately reducing efficiency, this invention provides an automatic sorting lithium battery dismantling and recycling device.

[0005] The technical solution of this invention is as follows: an automatic classification lithium battery dismantling and recycling device, comprising a collection frame, two liquid outlets provided on the lower front side of the collection frame, trapezoidal blocks connected to the lower left and right sides of the collection frame for limiting and guiding the broken battery liquid, dismantling components connected to the left and right sides of the collection frame for rapid crushing and dismantling of the lithium battery, and sieve plates connected to the left and right sides of the collection frame for blocking the broken solid fragments of the lithium battery, thereby achieving solid-liquid classification processing. It also includes: a diversion mechanism disposed on the collection frame for automatically identifying and diverting the lithium batteries to be processed; and a stabilizing mechanism disposed on the left and right sides of the collection frame for generating inert gas to block external air and cool and protect the broken lithium batteries.

[0006] In one embodiment, the diversion mechanism includes a fixed frame mounted on the upper part of the collection frame. The top of the fixed frame is a disc structure, and a first drive motor is mounted on the rear side of the upper disc structure of the fixed frame. The output shaft of the first drive motor is facing forward. Two symmetrical vision components are mounted on the inner side of the upper part of the fixed frame. The vision components are used to detect the specifications and status of the lithium battery. Four rotating rollers are rotatably connected to the upper part of the fixed frame. One of the rotating rollers is connected to the output shaft of the first drive motor. A transmission belt for conveying the diversion of 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 a gas storage component, which is installed on the right side of the collection frame. Two air inlet frames are connected between the gas storage component and the collection frame. The air inlet frames are connected and communicate with the collection frame. A cooling component is installed on the right side of the collection frame.

[0008] In one embodiment, a toggle mechanism is also included, which includes a second drive motor. The second drive motor is mounted on the lower rear side of the collection frame, and the output shaft of the second drive motor is oriented forward. A toggle frame for toggle lithium battery fragments is slidably connected inside the collection frame. The toggle frame has a U-shaped structure, and a lead screw is mounted on the output shaft of the second drive motor. The lead screw is rotatably connected to the collection frame.

[0009] In one embodiment, a discharge mechanism is also included, which includes a rotating plate. Two symmetrical rotating plates are rotatably connected to the front of the collection frame. Two pins are slidably connected to each rotating plate. The pins are engaged with the collection frame. A spring is connected between each pin and the adjacent rotating plate. The spring is sleeved on the corresponding pin. Two symmetrical push frames are slidably connected to the rear of the collection frame. The push frames are used to push the pins.

[0010] In one embodiment, a driving mechanism is also included, which includes a chuck. The chuck is rotatably connected to both the left and right sides of the upper part of the actuating frame. Each chuck has a locking groove, which can engage with the corresponding push frame. A rotating handle is connected to the rear side of each chuck.

[0011] In one embodiment, a feeding mechanism is also included, which includes a feeding frame. The feeding frame is bolted between the left and right sides of the fixed frame. Two inclined plates are installed inside the feeding frame, which are used to buffer and guide the feeding of lithium batteries.

[0012] In one embodiment, the pulley assembly consists of pulleys and a drive belt, with each pulley correspondingly mounted on the rotating roller, and the drive belt wound between the corresponding pulleys.

[0013] By adopting the above technical solution, the beneficial effects of the present invention are:

[0014] 1. In the process of dismantling and recycling lithium batteries, this invention relies on a sieve plate for solid-liquid separation. During the process, the specifications and status of the lithium batteries are detected in real time, and intelligent real-time diversion processing is carried out to avoid centralized processing of lithium batteries, which would affect the processing efficiency.

[0015] 2. When disassembling and crushing lithium batteries, the present invention requires the simultaneous activation of the gas storage component and the cooling component, so that the inert gas can cover the lower part of the collection frame to block the outside air and prevent the lithium battery from exploding. At the same time, the cooling component will quickly cool down to prevent other unexpected problems caused by excessive temperature.

[0016] 3. After the lithium battery is broken, in order to ensure that the solid and liquid are fully separated, the second drive motor can be started simultaneously. The rotation of the output shaft of the second drive motor will drive the lead screw to rotate, thereby causing the agitator to move back and forth along the collection frame. During the back and forth movement of the agitator, the lithium battery fragments accumulated on the screen plate will be agitated, thereby preventing the fragments from clogging the screen plate and preventing the battery liquid from flowing downward and separating.

Detailed Implementation

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

[0029] Example 1

[0030] An automated sorting and recycling device for lithium batteries, such as Figure 1 and Figure 2 As shown, the system includes a collection frame 1 with two liquid outlets 2 on the lower front side. Trapezoidal blocks 3 are connected to the lower left and right sides of the collection frame 1, which are used to limit and guide the broken battery liquid. Disassembly components 4 are connected to the left and right sides of the collection frame 1, which are used to quickly break and disassemble the lithium battery. Screen plates 5 are connected to the left and right sides of the collection frame 1, which are used to block the solid fragments of the broken lithium battery and achieve solid-liquid separation. The system also includes a diversion mechanism 6, which is set on the collection frame 1 and is used to automatically identify and divert the lithium battery to be processed. A stabilizing mechanism 7 is set on the left and right sides of the collection frame 1 and is used to generate inert gas to block external air and cool and protect the broken lithium battery.

[0031] It should be noted that this device can be used to disassemble and crush lithium batteries during lithium battery recycling. First, the lithium battery is placed on the diversion mechanism 6, and then the diversion mechanism 6 is activated. According to the specifications of the lithium battery, it is fed into the disassembly component 4. After the lithium battery is fed into the disassembly component 4, the disassembly component 4 will disassemble and crush the lithium battery. The crushed lithium battery will fall onto the sieve plate 5. Relying on the filtering and blocking effect of the sieve plate 5, solid-liquid separation is performed. At the same time, the stabilizing mechanism 7 is activated to allow inert gas to cover the lower part of the collection frame 1, preventing 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, achieving 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 side of the middle of the collection 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 facing forward. Two symmetrical vision components 63 are installed on the upper inner side of the fixed frame 61. The vision components 63 are used to detect the specifications and status of the lithium battery. Four rotating rollers 64 are rotatably connected to the upper part of the fixed frame 61. One of the rotating rollers 64 is connected to the output shaft of the first drive motor 62. A transmission belt for conveying the diversion of lithium batteries is wound between the rotating rollers 64. A pulley assembly 66 is connected between the rotating rollers 64. The pulley assembly 66 consists of pulleys and transmission belts. The pulleys are all installed on the rotating rollers 64, and the transmission belt is wound between the corresponding pulleys.

[0033] It should be noted that, firstly, the lithium battery is placed on the conveyor belt 65, and then the vision component 63 and the first drive motor 62 are activated. At this time, the vision component 63 will perform corresponding direction diversion processing on the lithium battery according to the specifications and status of the lithium battery, and in combination with the judgment of the disassembly component 4. Firstly, the rotation of the output shaft of the first drive motor 62 will drive the corresponding rotating roller 64 to rotate, thereby causing the pulley assembly 66 to drive the other rotating rollers 64 to rotate, and thus causing the conveyor belt 65 to transport the lithium battery. When some lithium batteries enter the disassembly component 4, the vision component 63 will detect a significant change in the number of lithium batteries and control the output shaft of the first drive motor 62 to rotate in the opposite direction, thereby causing the conveyor belt 65 to run in the opposite direction and send the lithium battery into the disassembly component 4 on the other side, realizing intelligent diversion processing and avoiding centralized processing of lithium batteries, which would affect processing efficiency.

[0034] like Figure 1 and Figure 5As shown, the stabilizing mechanism 7 includes a gas storage component 71. The gas storage component 71 is installed on the right side of the collection frame 1. Two air inlet frames 72 are connected between the gas storage component 71 and the collection frame 1. The air inlet frames 72 are connected and communicate with the collection frame 1. A cooling component 73 is installed on the right side of the collection frame 1.

[0035] It should be noted that when disassembling and crushing lithium batteries, the gas storage component 71 and the cooling component 73 need to be activated simultaneously so that the inert gas can cover the lower part of the collection frame 1, blocking the outside air and preventing the lithium battery from exploding. At the same time, the cooling component 73 will quickly cool down to prevent other unexpected problems from occurring due to excessive temperature.

[0036] Example 2

[0037] Based on Example 1, such as Figure 1 and Figure 6 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 lower rear side of the collection frame 1. The output shaft of the second drive motor 81 is arranged facing forward. A toggle frame 82 for toggle lithium battery fragments is slidably connected inside the collection frame 1. The toggle frame 82 has a Z-shaped structure. A lead screw 83 is installed on the output shaft of the second drive motor 81. The lead screw 83 is rotatably connected to the collection frame 1.

[0038] It should be noted that after the lithium battery breaks, in order to ensure sufficient solid-liquid separation, the second drive motor 81 can be started simultaneously. The rotation of the output shaft of the second drive motor 81 will drive the lead screw 83 to rotate, thereby causing the agitator 82 to move back and forth along the collection frame 1. During the back and forth movement of the agitator 82, the lithium battery fragments accumulated on the sieve plate 5 will be agitated, thereby preventing the fragments from clogging the sieve plate 5 and causing the battery liquid to be unable to flow downwards for separation.

[0039] like Figure 1 and Figure 7 As shown, it also includes a discharge mechanism 9, which includes a rotating plate 91. Two symmetrical rotating plates 91 are rotatably connected to the front of the collection frame 1. Two pins 92 are slidably connected to each rotating plate 91. The pins 92 are engaged with the collection frame 1. Springs 93 are connected between each pin 92 and the adjacent rotating plate 91. The springs 93 are sleeved on the corresponding pins 92. Two symmetrical push frames 94 are slidably connected to the rear of the collection frame 1. The push frames 94 are used to push the pins 92.

[0040] It should be noted that after the lithium battery is processed, the pusher 94 is pushed forward. During the forward movement of the pusher 94, the lithium battery fragments will be pushed forward, so that the lithium battery fragments can be concentrated and moved to the front of the collection box 1. When the pusher 94 moves to the limit position, the pusher 94 will push the pin 92, so that the pin 92 is disengaged from the collection box 1. At this time, the rotating plate 91 will automatically flip down and open, making it easy for the operator to remove the lithium battery fragments.

[0041] like Figure 1 , Figure 8 and Figure 9 As shown, it also includes a driving mechanism 10, which includes a cam 101. The cam 101 is rotatably connected to the left and right sides of the upper part of the actuating frame 82. Each cam 101 has a locking groove, which can engage with the corresponding push frame 94. Each cam 101 has a rotating handle 102 connected to its rear side.

[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 push frame 94, the rotating handle 102 can be controlled to rotate the locking wheel 101, so that the locking groove on the locking wheel 101 can engage with the push frame 94. At this time, the second drive motor 81 can be started directly to drive the actuating frame 82 to move, so that the push frame 94 can move forward automatically.

[0043] like Figure 1 and Figure 10 As shown, it also includes a feeding mechanism 11, which includes a feeding frame 111. The feeding frame 111 is bolted between the left and right sides of the fixed frame 61. Two inclined plates 112 are installed inside the feeding frame 111. The inclined plates 112 are used to buffer and guide the feeding of lithium batteries.

[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, avoiding abnormalities caused by feeding too much at once.

[0045] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in 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 that conforms to the innovative features mentioned in the claims.
