[0001] The present invention relates to the technical field of battery disassembly, and more particularly to an automated disassembly device and method for waste lithium iron phosphate batteries. Background Art

[0002] With the vigorous development of the electric vehicle industry, the number of waste lithium iron phosphate batteries has increased dramatically. How to deal with these waste batteries efficiently and safely has become an urgent problem to be solved. The traditional manual disassembly method is not only inefficient and requires a lot of manpower and time, but also due to the differences in the skill levels of operators, the disassembly quality is difficult to guarantee. At the same time, manual disassembly also has certain safety risks, such as battery short circuit and explosion.

[0003] In order to improve disassembly efficiency, some automated disassembly equipment has been introduced into the field of battery recycling. However, existing automated disassembly equipment still faces challenges when processing waste lithium iron phosphate batteries of different sizes. Due to the diversity of battery sizes and shapes, automated disassembly equipment often finds it difficult to accurately cut both ends of the battery at one time. It usually needs to be done in steps, that is, cutting one side first and then the other side. This results in a long disassembly process and low work efficiency. In order to solve the above problems, an automated disassembly equipment and disassembly method for waste lithium iron phosphate batteries are proposed. Summary of the Invention

[0017] The present invention is further configured such that one end of the connecting bracket is fixedly connected to the telescopic end of the second cylinder push rod, and a slider is provided on the end of the connecting bracket away from the second cylinder push rod;

[0018] A sliding groove is provided on one side of the transverse plate, and the sliding groove and the sliding block are slidably matched.

[0028] Compared with the prior art, the present invention provides an automated disassembly device and method for waste lithium iron phosphate batteries, which has the following beneficial effects:

[0029] 1. The positioning clamping assembly and the cutting tool assembly in the present invention are synchronously adjusted through a connecting bracket, so that when clamping batteries of different sizes, the cutting tool assembly can automatically adjust to the appropriate position, achieving precise cutting of both ends of the battery at one time. This design avoids the problem of step-by-step cutting required in traditional disassembly equipment, significantly shortens the disassembly time, and improves the overall disassembly efficiency.

[0030] 2. The positioning and clamping assembly of the present invention adopts an elastic push plate design, which provides a buffer through the reset spring to avoid direct squeezing of the battery cells inside the cutting process, thereby reducing the risk of explosion. At the same time, the design of the offset plate effectively separates the two ends of the cut battery shell when the battery cell is pushed out, preventing the battery cell and shell fragments from mixing, which facilitates subsequent sorting.

[0031] 3. In the present invention, the hydraulic cylinder is positioned by engaging the positioning tooth block on the horizontal plate with the positioning rack in the first sliding groove, thereby achieving high stability during the cutting process, effectively avoiding the deviation of the cutting knife caused by the deformation of the connecting bracket, and thus preventing the risk of battery cell explosion caused by the cutting knife contacting the battery cell.

[0041] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0042] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0043] In the present invention, unless otherwise specified, directions such as "up" and "down" are generally used with respect to the directions shown in the drawings, or with respect to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" are generally used with respect to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0044] For examples, see Figure 1 - Figure 8 , an automated disassembly device and method for waste lithium iron phosphate batteries, comprising a conveying platform 1, and a cutting mechanism 2 and a shell-core separation mechanism 3 are sequentially arranged at the rear of the conveying platform 1;

[0045] The cutting mechanism 2 includes a support assembly 4 disposed on the conveying platform 1, a positioning clamping assembly 5 disposed on both sides of the support assembly 4, and a cutting tool assembly 6 disposed on the top of the support assembly 4;

[0046] A connecting bracket 7 is provided between the positioning and clamping assembly 5 and the cutting tool assembly 6, and when the positioning and clamping assembly 5 clamps batteries of different sizes, the cutting position of the cutting tool assembly 6 can be synchronously adjusted through the connecting bracket 7;

[0047] The shell-core separation mechanism 3 includes a support frame 301 arranged on the conveying platform 1 , a first cylinder push rod 302 arranged on one side of the support frame 301 , and a hydraulic jack 303 arranged on the top of the support frame 301 .

[0048] The conveying platform 1 is used to convey waste lithium iron phosphate batteries, and the cutting mechanism 2 is used to first clamp the waste lithium iron phosphate batteries of different sizes in the center, and then cut the two ends of the battery through the cutting tool assembly 6, thereby opening the two ends of the battery shell, and then the shell-core separation mechanism 3 is used to push out the battery cells in the lithium iron phosphate battery with the two ends of the battery shell opened, thereby realizing the automatic disassembly of the battery cells and the shell.

[0049] Among them, visual sensors are provided on one side of the cutting mechanism 2 and the shell-core separation mechanism 3. When the conveying platform 1 conveys the waste lithium iron phosphate battery to the bottom of the cutting mechanism 2 and the shell-core separation mechanism 3, the conveying platform 1 will stop, so that the waste lithium iron phosphate battery can be disassembled.

[0050] Specifically, the cutting mechanism 2 first clamps the two ends of waste lithium iron phosphate batteries of different sizes through the positioning and clamping assembly 5. When the positioning and clamping assembly 5 pushes the battery to be clamped in the center, it will drive the cutting tool assembly 6 to adjust its position through the connecting bracket 7, so that after the waste lithium iron phosphate battery is clamped, the cutting tool assembly 6 is synchronously adjusted to the top of the two ends of the waste lithium iron phosphate battery to be cut. It should be noted that in the initial state, the longitudinal projection distance between the cutting tool assembly 6 and the positioning and clamping assembly 5 is small, but it can achieve cutting of the end of the battery shell without cutting the battery cells in the battery. Then, the cutting tool assembly 6 with the adjusted position is pressed down to achieve cutting of the two ends of the battery shell, thereby opening the two ends of the battery shell.

[0051] Furthermore, after both ends of the used lithium iron phosphate battery shell are opened, the battery continues to move with the conveyor platform 1. When it moves to the position of the shell-core separation mechanism 3, the hydraulic jack 303 presses the battery into position by pressing down, and then pushes the battery cell in the battery shell out through the first cylinder push rod 302, so that the battery cell is discharged from the side of the conveyor platform 1 away from the first cylinder push rod 302, and the battery shell will be transported to the tail through the conveyor platform 1 and fall into the collection frame.

[0052] The bracket assembly 4 includes support side plates 401 provided on both sides of the conveying platform 1, and the positioning clamping assembly 5 is fixedly installed on the lower end of the support side plates 401;

[0053] The positioning and clamping assembly 5 includes a second cylinder push rod 501 provided at the lower end of the supporting side plate 401 , and a push plate member 8 provided at the end of the telescopic rod of the second cylinder push rod 501 .

[0054] The second cylinder push rods 501 are fixedly installed on the supporting side plates 401 on both sides, and the telescopic rods of the second cylinder push rods 501 on the two groups of supporting side plates 401 pass through the supporting side plates 401 and extend to above the conveying platform 1. When the telescopic rods of the two groups of second cylinder push rods 501 are extended, they drive the push plate parts 8 to move closer to each other, thereby pushing the waste lithium iron phosphate batteries on the conveying platform 1 and clamping the waste lithium iron phosphate batteries in the center.

[0055] The telescopic end of the second cylinder push rod 501 is provided with an active cavity 502, and the push plate 8 is matched and plugged into the active cavity 502;

[0056] The push plate member 8 includes a return spring 801 disposed in the movable cavity 502 , an insertion rod 802 movably inserted in the movable cavity 502 , and a push plate 803 disposed at the other end of the insertion rod 802 .

[0057] When the second cylinder push rod 501 drives the push plate 8 to clamp the used lithium iron phosphate battery, the push plate 803 first fits the used lithium iron phosphate battery. As the second cylinder push rod 501 continues to push, the push plate 803 is inserted into the active cavity 502 through the plug-in rod 802 to squeeze the return spring 801, so that the return spring 801 has a rebound force, and the battery is clamped by the rebound force of the return spring 801.

[0058] It should be noted that when the battery is clamped, in order to ensure a higher clamping force, the push plate 803 is as close to the telescopic end of the second cylinder push rod 501 as possible, but the telescopic end of the push plate 803 and the second cylinder push rod 501 need to maintain a certain distance. The purpose is to enable the cutter assembly 6 to push the cut ends of the battery shell to the sides when cutting the two ends of the battery shell, so as to ensure that the cutting tool assembly 6 can stably cut vertically downward. If the push plate 803 bracket is welded to the telescopic end of the second cylinder push rod 501, then after the battery is clamped, there is no buffer offset spacing. When the cutting tool assembly 6 is pressed down for cutting, as the cutting tool assembly 6 enters, it will squeeze the battery shell and the battery cell, that is, there is a possibility of safe cutting and cutting the battery cell. Therefore, when the battery shell is cut, there is a possibility of battery cell explosion. Through the setting of the reset spring 801 and the push plate 803, the distance can provide a buffer for the cut end of the battery shell, thereby preventing the cutting tool assembly 6 from deviating toward the battery cell and causing battery cell explosion.

[0059] The positioning and clamping assembly 5 further includes an electric telescopic rod 503 provided on one side of the push plate 803, and a dislocation plate 504 provided on the telescopic end of the electric telescopic rod 503;

[0060] When the electric telescopic rod 503 is in the retracted state, the offset plate 504 is in contact with one end of the push plate 803 close to the shell-core separation mechanism 3, and the side of the offset plate 504 away from the supporting side plate 401 protrudes from the side of the push plate 803 away from the supporting side plate 401.

[0061] After the battery shell is cut by the cutting tool assembly 6, as it is transported by the conveyor table 1, the two ends of the cut battery shell fall to the side at the two ends of the battery. When it moves to the position of the shell-core separation mechanism 3, the first cylinder push rod 302 pushes the battery cell out of the shell. When the battery cell is disassembled from the battery shell, it will conflict with the battery shell that has fallen to the side after cutting, so that the battery cell and the battery shell are collected together, which requires manual sorting later.

[0062] The electric telescopic rod 503 is fixedly installed on the side of the plug-in rod 802 on the push plate 803. Through the setting of the dislocation plate 504, before the push plate 803 clamps the battery, the electric telescopic rod 503 is in an extended state. After the push plate 803 clamps the battery and completes the cutting, the electric telescopic rod 503 contracts, driving the dislocation plate 504 to fit one side of the battery. At this time, the conveyor 1 starts to convey the battery and the cut ends. The cut ends of the battery shell are interfered by the dislocation plate 504 and will be intercepted, while the middle end of the shell loaded with the battery cell can be conveyed normally. The two ends of the intercepted battery shell and the middle end of the shell loaded with the battery cell are misaligned. The two ends of the dislocated battery shell are not limited by the middle end of the shell loaded with the battery cell, and will fall sideways and disengage from the interference of the dislocation plate 504. As a result, it can be conveyed along with the conveyor 1, so that when the first cylinder push rod 302 pushes the battery cell out of the shell, it will not be collected together with the cut end of the battery shell.

[0063] It should be noted that when the conveyor table 1 moves the cut battery, the second cylinder push rod 501 will contract, thereby resetting the reset spring 801, and there is no reaction force to clamp the battery, and the push plate 803 and both ends of the battery are in a zero contact state, which is used for limiting.

[0064] The bracket assembly 4 further includes a limiting frame 402 disposed between the two sets of supporting side plates 401, and a first sliding groove 403 and a second sliding groove 404 formed on the limiting frame 402;

[0065] The cutting tool assembly 6 includes a horizontal plate 601 slidably mounted in the first sliding groove 403 , a hydraulic cylinder 602 fixedly mounted at both ends of the horizontal plate 601 , and a cutting knife 603 fixedly mounted at the telescopic end of the hydraulic cylinder 602 .

[0066] The first sliding groove 403 is connected to the second sliding groove 404. The first sliding groove 403 is horizontally opened at the middle position of the limiting frame 402, and the second sliding groove 404 is longitudinally opened at both ends of the width direction of the limiting frame 402. The width direction is the conveying direction of the conveying platform 1. Figure 1 and Figure 2 The hydraulic cylinder 602 is slidably installed in the second sliding groove 404, and the hydraulic cylinder 602 is limited by the second sliding groove 404. The hydraulic cylinder 602 is driven by the cross plate 601 to move horizontally in the width direction of the conveying platform 1.

[0067] One end of the connecting bracket 7 is fixedly connected to the telescopic end of the second cylinder push rod 501, and a slider 701 is provided at the end of the connecting bracket 7 away from the second cylinder push rod 501;

[0068] A sliding groove 604 is provided on one side of the horizontal plate 601 , and the sliding groove 604 and the slider 701 are slidably matched.

[0069] A positioning tooth block 605 is provided at the top of the middle section of the transverse plate 601 , and a positioning rack 405 is provided at the top of the inner wall of the first sliding groove 403 , and the positioning tooth block 605 and the positioning rack 405 are engaged and matched.

[0070] The height of the first sliding groove 403 is greater than the thickness of the horizontal plate 601 , and when the horizontal plate 601 is attached to the bottom end of the first sliding groove 403 , the positioning tooth block 605 and the positioning rack 405 are in a separated state.

[0071] When cutting the two ends of the battery shell, if the connecting bracket 7 and the cross plate 601 are fixedly connected, the reaction force of the cutting knife 603 acts on the hydraulic cylinder 602 when cutting the battery shell, because the hydraulic cylinder 602 is only supported and limited by the connecting bracket 7, and the connecting bracket 7 is connected to the second cylinder push rod 501, and its size is longer. Therefore, when cutting, the connecting bracket 7 is not stable enough to limit the position of the hydraulic cylinder 602. Once the connecting bracket 7 is deformed, the cutting knife 603 is driven to deviate, which can easily cause the cutting knife to hit the battery cell, thereby causing the battery cell to explode.

[0072] The hydraulic cylinder 602 is positioned by engaging the positioning tooth block 605 on the transverse plate 601 with the positioning rack 405 in the first sliding groove 403, thereby achieving stability during cutting.

[0073] Specifically, under the action of gravity, the hydraulic cylinder 602 drives the cross plate 601 to fit the bottom end of the first sliding groove 403, so that the positioning tooth block 605 and the positioning rack 405 are in contact with the battery shell when cutting the two ends of the battery shell. Then, its reaction force pushes the hydraulic cylinder 602 to drive the cross plate 601 to move upward along the slider 701, so that the positioning tooth block 605 and the positioning rack 405 are engaged and positioned. At this time, when cutting, the position of the hydraulic cylinder 602 will not shift, thereby ensuring safety and stability during cutting.

[0074] A rubber block 304 is fixedly mounted on the telescopic end of the first cylinder push rod 302 , and a pressure block 305 is provided on the bottom end of the hydraulic jack 303 .

[0075] The provision of the rubber block 304 prevents the battery cell from being squeezed and damaged when it is pushed, thereby preventing the battery cell from exploding.

[0076] S1. Place the waste lithium iron phosphate battery on the conveyor platform 1. The conveyor platform 1 conveys the battery to the bottom of the cutting mechanism 2 and stops. The positioning clamping assembly 5 clamps the battery in the center;

[0077] S2. The connecting bracket 7 of the cutting mechanism 2 drives the cutting tool assembly 6 to be synchronously adjusted to above the two ends of the battery. The hydraulic cylinder 602 of the cutting tool assembly 6 drives the cutting knife 603 to press down, cutting the two ends of the battery shell and opening the battery shell;

[0078] S3. After the cutting is completed, the conveyor 1 continues to move, conveys the cut batteries to the bottom of the shell-core separation mechanism 3 and stops, preparing to separate the battery core from the shell;

[0079] S4: The hydraulic push column 303 of the shell-core separation mechanism 3 presses down to press the battery into position, and the first cylinder push rod 302 pushes the battery cell in the battery shell through the rubber block 304 to separate the battery cell from the shell;

[0080] S5. The battery cells are discharged from one side of the conveyor platform 1 for collection, and the battery shells continue to be transported to the tail through the conveyor platform 1 and fall into the collection frame, completing the entire disassembly process.

[0081] In all the schemes mentioned above, the connection between the two parts can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by those skilled in the art that various changes, modifications, substitutions and deformations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
