Description

Technical Field

[0001] This invention relates to the field of battery recycling technology, specifically to a device for separating and classifying recyclable power battery modules using a potting compound encapsulation system. Background Technology

[0002] With the rapid development of new energy vehicles, energy storage equipment, and other fields, the installed capacity and scrap volume of power batteries have continued to surge. The recycling of power batteries has become a crucial link in ensuring resource circulation and reducing environmental risks. Among them, potting-type integrally encapsulated power batteries are widely used in harsh working conditions or scenarios with high safety requirements due to their advantages such as stable structure, waterproof and dustproof properties, and strong impact resistance. The core encapsulation feature of this type of power battery is that the battery shell and the internal battery module (including cells, busbars, circuit boards, and other components) are integrally fixed using high-strength structural adhesives (such as epoxy resin adhesives and polyurethane adhesives). The adhesive layer fills the gaps between the shell and the module, as well as between adjacent battery modules, firmly bonding the shell, module, cells, and other components into an inseparable integral structure. Its encapsulation strength is far higher than that of traditional snap-fit ​​and bolt-fixed power batteries.

[0003] However, the structural characteristics of the potting and encapsulation system pose significant challenges to the recycling process. Existing power battery recycling technologies are difficult to adapt to the dismantling requirements of this type of product, mainly due to the following drawbacks:

[0004] Traditional dismantling techniques are completely unsuitable: Conventional power battery recycling is mostly for structures with clips, bolts, or simple adhesives. Mechanical extrusion, vibration separation, and high-temperature heat melting can be used to separate the outer shell from the module. However, the adhesive layer of potted and encapsulated power batteries has high bonding strength and wide coverage. Mechanical extrusion can easily lead to cell deformation, short circuits, and fires. High-temperature heat melting will damage the performance of the cell's active materials and metal matrix. Vibration separation cannot break through the strong adhesive layer. None of these methods can effectively separate the outer shell from the module or the modules from each other.

[0005] Current manual disassembly methods are inefficient and unsafe: Currently, the disassembly of encapsulated power batteries in the industry largely relies on manual operation. Simple tools such as angle grinders and chisels are used to violently cut the outer shell and remove the adhesive layer. This is not only labor-intensive and extremely inefficient, but also poses the following risks: First, the internal cells are easily touched during the cutting process, which may cause short circuits, combustion, or even explosions; second, adhesive layer debris and cell dust spread, endangering the health of operators; and third, violent disassembly damages the module structure, making it difficult to achieve the classification and recycling of cells, resulting in low resource utilization.

[0006] Due to the differences in adhesive layer thickness, bonding position, and shell material (aluminum alloy, plastic, etc.) of potted integrally packaged power batteries, and the irregular filling state of the adhesive layer between adjacent modules, the cutting machine cannot adaptively adjust the separation force and angle, which can easily cause safety hazards such as module breakage and electrolyte leakage. Therefore, the safe disassembly of this type of battery is still mainly done manually, supplemented by machinery.

[0007] In summary, given the structural characteristics of potting-encapsulated power batteries, there is an urgent need for a dismantling and recycling technology that balances safety, efficiency, and operability. This technology should address the technical challenges of poor dismantling adaptability, high safety risks, and low resource recycling rates in existing technologies through a combination of manual and mechanical methods. Summary of the Invention

A suction port corresponding to the opening of the dust collection hood is provided at the bottom of the housing. A flexible hose is provided at the top of the dust collection hood, and the other end of the flexible hose extends out of the housing and is connected to a first suction fan.

[0015] Preferably, the cutting mechanism includes a mounting plate on a platform, a first electric slide on the mounting plate along its length, a second electric slide on the slider of the first electric slide, a second motor on the slider of the second electric slide, a cutting blade on the output end of the second motor, a movable baffle on the platform below the second motor, and the baffle being parallel to the mounting plate.

The bottom of the dust suction hole is connected to a second dust suction fan through a hose, and the outlet of the second dust suction fan is connected to a dust collection box through a hose.

[0018] Preferably, the platform is provided with a fixing mechanism, which includes a fixing plate. The top of the fixing plate has an adjustment groove along its height direction. A pressure plate in the shape of a "┏" is provided in the adjustment groove. The vertical part of the pressure plate extends into the adjustment groove, and a rubber pad is provided at the bottom of the horizontal part of the pressure plate.

[0019] Preferably, a third motor is provided at the bottom of the platform, and a screw is provided at the output end of the third motor. The screw passes through the platform and the fixing plate in sequence, extends into the vertical part of the pressure plate, and is threadedly connected.

[0020] The present invention has the following beneficial effects:

[0021] 1. This invention constructs an integrated disassembly system that combines precise manual execution with mechanical assistance. The cutting and disassembly areas are linked through process coordination and structural collaboration to form an organic whole. Through a continuous process of "directional cutting of the outer shell → positioning and fixing of the module → precise separation of the adhesive layer → classification and recycling of the module", the safe and efficient disassembly of the encapsulated power battery is achieved.

[0022] 2. This invention addresses the core structural characteristics of integrally packaged power battery casings and modules, as well as the strong bonding between modules through high-strength adhesive layers. It establishes an integrated cutting-disassembly-recycling technology system, where the cutting and disassembly mechanisms work together to achieve safe, efficient, and precise disassembly of this type of battery. Addressing the characteristics of high adhesive strength and irregular filling in integrally packaged power batteries, the cutting mechanism allows for baffle position adjustment via a lead screw to accommodate different casing thicknesses and adhesive layer distributions. The disassembly mechanism's disassembly blade and separation plate form a cutting-separation linkage. The disassembly blade precisely cuts the adhesive layers between modules, and the separation plate then opens to achieve smooth module separation. Even with irregularly filled adhesive layers, manual adjustment of the operating angle allows for adaptive disassembly. Compared to traditional mechanical extrusion and high-temperature hot-melt techniques, this invention does not cause cell deformation or damage to active materials. Compared to purely manual and forceful disassembly, it maximizes the preservation of module integrity and significantly improves resource recycling rates.

[0023] 3. The core function of the cutting mechanism in this invention is directional shell breaking. Through the coordinated drive of the first and second electric slides, combined with the depth limiting of the movable baffle, non-destructive and precise cutting of the battery shell is achieved, reserving a stable working channel for subsequent disassembly. The core function of the disassembly mechanism is layered separation. The disassembly blade precisely cuts the adhesive layer between modules along the cutting channel, and the separation plate follows to open the modules, forming a continuous operation chain of "cutting-adhesive breaking-separation". The two functions are closely linked. The cutting mechanism provides the operating basis for the disassembly mechanism, and the disassembly mechanism transforms the shell breaking effect of the cutting mechanism into the final separation result. Together, they constitute a complete disassembly process of shell separation-adhesive layer breaking-module disassembly, reflecting the overall technical concept of step-by-step implementation and layer-by-layer progression.

[0024] 4. The cutting mechanism used in this invention combines programmed control of an electric slide table with manual fine-tuning to adapt to the diverse needs of different shell materials and thicknesses. The disassembly mechanism adopts a combination of manual hand-held operation and motor-driven separation, utilizing human experience to avoid cutting deviations while achieving uniform force application through a gear-rack driven separation plate. Both follow a control logic of human-assisted decision-making combined with precise mechanical execution, overcoming the bottleneck of fully automated equipment's inability to adapt to irregular adhesive layers and structural differences, and also overcoming the inefficiency and safety hazards of purely manual operation, forming a collaborative control system where humans empower machinery and machinery assists humans.

[0025] 5. The cutting blade and electric slide of the cutting mechanism disclosed in this invention, and the disassembly blade and separating component of the disassembly mechanism are all modular components, which can be replaced or adjusted according to different battery models and module sizes; the telescopic component allows the separating plate to extend and retract flexibly to adapt to the operational needs of different disassembly stages. This modular design reduces equipment maintenance costs while improving adaptability to different specifications of potted integrally packaged power batteries.

[0026] 6. The device disclosed in this invention requires no complex programming or professional skills. Operators only need simple training to master skills such as adjusting cutting parameters and handheld disassembly operations, which is in line with the current industry trend of disassembly mainly relying on manual assistance and machinery. At the same time, the equipment has a compact structure and small footprint, making it suitable for the operating scenarios of small and medium-sized recycling companies or repair stations, and has broad prospects for promotion and application.

Detailed Implementation

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Unless otherwise specified, the technical means used in the implementation examples are conventional means well known to those skilled in the art.

[0041] refer to Figures 1-10 This invention discloses a device for separating, classifying, and recycling integrally encapsulated power battery modules, including a platform 1. The platform 1 is divided into a cutting area and a disassembly area. The cutting area is equipped with a cutting mechanism, and the disassembly area is equipped with a disassembly mechanism. The cutting mechanism cuts the battery casing, and the disassembly mechanism manually disassembles and classifies the internal components of the cut battery step by step. The disassembly mechanism includes a housing 2, within which a disassembly blade 4 is sleeved and fixed on a drive shaft 3. Specifically, the disassembly blade is sleeved and fixed in the middle of the drive shaft, and both ends of the drive shaft are fixed to the housing by bearings. The drive shaft can be driven by pulleys and a motor. Figure 5 As shown. The housing 2 is provided with a through hole 5 for the disassembly blade 4 to extend out, as shown. Figure 4 As shown, the through hole is located at the bottom corner of the housing, and the bottom and one side of the edge of the disassembly blade are located outside the housing, making it easy for the operator to observe the cutting area and avoid incorrect cutting position. A separating component is provided on the side of the disassembly blade 4, which corresponds longitudinally to the cutting blade. As the cutting blade moves forward, the separating component then performs the separation operation, which can further open and separate adjacent battery modules.

[0042] Specifically: The separating component includes a gantry frame 6, with a fixed shaft 7 installed within the frame area of ​​the gantry frame 6. The two ends of the fixed shaft are fixed to the surfaces of the two vertical plates of the gantry frame. Two rotatable separating plates 8 are mounted on the fixed shaft 7. A strip-shaped hole 9 is provided at the bottom of the housing 2 for the separating plates 8 to extend out. The two separating plates 8 are controlled to open or close by a control plate 10. When the two separating plates 8 are closed, the two control plates 10 are open. The length direction of the separating plates 8 is aligned with the radial direction of the disassembly blade 4. It should be noted that a driving component is provided between the two control plates 10 to drive them to move simultaneously towards or away from each other, thereby driving the two separating plates to open or close, ultimately separating adjacent parts.

[0043] Specifically: a first fixing ring 11 and a second fixing ring 12 are sleeved on the fixed shaft 7; the separating plates 8 are respectively disposed at the bottom of the first fixing ring 11 and the second fixing ring 12; and the control plates 10 are respectively disposed at an angle near the top of the first fixing ring 11 and the second fixing ring 12, as shown below. Figure 7-10 As shown, in one embodiment, there are two first fixing rings. The separation plate is fixed to the bottom of the two first fixing rings, and the control plate is tilted and fixed near the top of the two first fixing rings, i.e., the control plate is tilted at a certain angle to the first fixing rings. There is one second fixing ring, positioned between the two first fixing rings and of suitable length. The control plate is tilted and fixed near the top of the second fixing ring, and the separation plate is fixed to the bottom of the second fixing ring. When the second fixing ring is placed at the notch between the two first fixing rings and is coaxial, the fixing shaft passes through the two fixing rings. At this time, the two control plates are open in a V-shape, while the separation plate is in a closed state. Figure 9 As shown in the diagram, this is the initial state. To facilitate the insertion of the separating plates into the grooves cut by the disassembly blade, the outward-facing sides of both separating plates have inclined surfaces that slope towards the mating surfaces of the two separating plates. The opening angle of the two control plates determines the opening angle of the two separating plates, which can be set according to actual needs. The number of the first and second fixing rings is determined based on the length of the separating plates.

[0044] Furthermore, to make the first and second fixed rings rotate more smoothly on the fixed shaft with the control plate and the separation plate, notches are provided on the corresponding sides of the separation plate and the control plate between the two first fixed rings. Similarly, notches are provided on the corresponding sides of the separation plate and the control plate at both ends of the second fixed ring, so that the two control plates and the separation plate will not collide or rub against each other during movement.

[0045] Furthermore, the control plate is provided with through holes 42 corresponding to the rack on the other control plate. This prevents the rack from abutting against the corresponding control plate when the rack is too long or the angle between the two control plates is too large, thus preventing the separation plate from opening further. Therefore, by providing through holes, the rack can pass through the through holes 42 under the rotation of the gear, thereby opening the separation plate to the maximum extent.

[0046] Furthermore, the driving component includes a first rack 13 and a second rack 14 respectively mounted on the two control plates 10. The two racks are arc-shaped and staggered. The first rack 13 and the second rack 14 are concentric with the fixed shaft 7. A gear 15 is disposed between the first rack 13 and the second rack 14, meshing with the first and second racks. When the gear rotates, it simultaneously drives the two racks, along with their respective connected control plates, to rotate around the fixed shaft. The gear 15 is sleeved and fixed on a rotating shaft 16. A first motor 17 is mounted at one end of the rotating shaft 16. The rotating shaft 16 and the fixed shaft 7 are located on the same plane in the vertical direction. It should be noted that the first motor is fixed to the outer wall of the portal frame, and its rotating shaft passes through the portal frame and is fixed by a bearing. The gear is sleeved and fixed on the rotating shaft, and multiple gears can be provided depending on the width of the racks. The teeth on the two racks face opposite directions, one downwards and the other upwards. Figure 9 As shown, the teeth of the upper rack face downwards, and the teeth of the lower rack face upwards.

[0047] Furthermore, since there are situations where the separation plate is not needed, it needs to be retracted into the housing. Specifically: The bottom of the two vertical plates of the portal frame 6 has extension slots along their height direction. An extension plate 18 is installed within these slots. One end of the extension plate 18 at the opening of the extension slot is fixed to the inner bottom of the housing 2. A telescopic component 19 is installed at the top of the horizontal plate of the portal frame 6, and a handle 20 is installed at the top of the housing 2, allowing operators to easily manipulate the entire disassembly mechanism. The telescopic component includes, but is not limited to, electric push rods and hydraulic push rods. The drive rod of the telescopic component passes through the top of the housing and extends into the housing, fixing itself at the center of the horizontal plate of the portal frame. When the telescopic component is activated, it moves the portal frame up and down, retracting the separation plate into the housing or extending it out of the housing.

[0048] Furthermore, to prevent the disassembly blade from generating excessive dust during cutting, which could affect the health of operators and pollute the environment, a dust collection component is provided between the disassembly blade 4 and the separating component. This dust collection component includes a dust collection hood 21 located at the bottom of the housing 2 with its opening facing downwards. The bottom of the housing 2 has a suction port corresponding to the opening of the dust collection hood 21. A flexible hose is attached to the top of the dust collection hood 21, with the other end extending outside the housing 2 and connected to a first vacuum cleaner. The collected dust is then gathered into a collection box by the first vacuum cleaner. The hose is a telescopic hose, allowing it to extend within a certain range. When using the first vacuum cleaner, the hose is connected to it; when not in use, it can be disconnected, making disassembly convenient and highly flexible.

[0049] Furthermore, when disassembling the battery module, it needs to be secured. Therefore, a fixing mechanism is provided on the platform 1. The fixing mechanism includes a fixing plate 35 vertically fixed on the platform. The top of the fixing plate 35 has an adjustment groove along its height direction. A "┏"-shaped pressure plate 36 is provided in the adjustment groove. The vertical part of the pressure plate 36 extends into the adjustment groove, and a rubber pad 37 is provided at the bottom of the horizontal part of the pressure plate 36. The battery to be disassembled is pressed and secured by the horizontal part of the pressure plate.

[0050] Furthermore, a third motor 38 is provided at the bottom of the platform 1, and a screw 39 is provided on the output end of the third motor 38. The screw 39 passes through the platform 1 and the fixing plate 35 in sequence, extends into the vertical part of the pressure plate 36 and is threadedly connected. By starting the third motor, the height of the pressure plate is adjusted, thereby better fixing the battery, while the rubber pad increases the friction to prevent the battery from falling off the pressure plate.

[0051] Furthermore, during the disassembly of the battery module, the battery casing needs to be cut. Therefore, the cutting mechanism includes a mounting plate 22 mounted on platform 1. A first electric slide 23 is mounted on the mounting plate 22 along its length. A second electric slide 40 is vertically mounted on the slider of the first electric slide 23. A second motor 24 is mounted on the slider of the second electric slide 40. A cutting blade 25 is horizontally mounted at the output end of the second motor 24. Below the second motor 24, a movable baffle 26 is mounted on platform 1, parallel to the mounting plate 22. It should be noted that the first and second electric slides enable the second motor to move in the X and Z axes, allowing adjustment of the cutting height. The movable baffle allows adjustment of the cutting depth.

[0052] Specifically: A lead screw 27 is fixed to the bottom of the platform 1 via a bearing seat. A lead screw nut 28 is fitted onto the lead screw 27. An adjustment hole 29, which is rectangular, is provided through the platform 1. A fixing block 30 is provided on the lead screw nut 28. The fixing block 30 is located inside the adjustment hole 29 and fixed to the bottom center of the baffle 26. The lead screw 27 and the adjustment hole 29 are perpendicular to the baffle 26. By rotating the lead screw, the lead screw nut is driven to move along the adjustment hole, thereby causing the baffle to move towards or away from the mounting plate, thus achieving adjustment of the cutting depth. The rotation of the lead screw can be driven by a motor or manually adjusted. A motor or adjustment knob can be installed at one end of the lead screw as needed.

[0053] Furthermore, in order to increase the stability of the fixed block during movement, a sliding groove 43 is provided on both sides of the adjustment hole along its length, and a guide post 44 extending into the sliding groove is provided on both sides of the fixed block, so that the fixed block moves along the sliding groove during movement, thereby maximizing the stability of the fixed block during operation.

[0054] Furthermore, to ensure the stability of the baffle during movement, auxiliary holes are provided on both sides of the adjustment hole. These auxiliary holes are the same size and orientation as the adjustment hole, and guide rods 41 are installed inside them. A guide block is provided at the bottom of the baffle for the guide rods 41 to pass through, thus ensuring the stability of the baffle during movement and supporting the battery. When cutting the battery casing, the distance between the baffle and the cutting blade is adjusted according to the thickness of the battery casing, so that one side of the battery rests against the baffle. The cutting position and height are adjusted using the first and second electric slides. Then, the second motor is started, and the battery casing is cut under the action of the first electric slide. The battery is then manually rotated so that the uncut side rests against the baffle, and cutting continues until all four sides of the battery casing are cut. Finally, the battery is disassembled step by step using a disassembly mechanism.

[0055] Similarly, to reduce the large amount of dust generated during cutting, a dust suction hole 31 is provided through the platform 1. The dust suction hole 31 is located between the baffle 26 and the mounting plate 22, and is arranged along the length of the mounting plate 22. The top of the dust suction hole 31 is provided with a dust suction cover 32 with an opening facing the baffle 26. The bottom of the dust suction hole 31 is connected to a second dust suction fan 33 through a flexible hose. The outlet of the second dust suction fan 33 is connected to a dust collection box 34 through a flexible hose. It should be noted that the size and number of dust suction holes are set according to actual needs, and the number of flexible hoses connected to the dust suction holes is also set according to needs. Multiple flexible hoses are connected to a main pipe and then connected to the second dust suction fan. It is not necessary to set up multiple dust suction fans.

[0056] When using this invention, the battery is placed on the platform. The distance between the baffle and the cutting blade is adjusted by rotating the lead screw according to the thickness of the battery casing. The battery is then pressed against the baffle. The second electric slide adjusts the height of the second motor to adjust the cutting height. Then, the second motor and the first electric slide are started to cut the battery casing. After cutting, the first electric slide can be manually rotated without resetting the second motor, so that the uncut side continues to press against the baffle. The first electric slide and the second motor are then started again to continue cutting. It should be understood that the forward and reverse rotation of the first electric slide enables the reciprocating motion of the second motor. Following the above operation, all four sides of the battery are cut. After cutting, because the battery casing is filled with adhesive, it cannot be manually removed. At this point, disassembly is required in the disassembly area.

[0057] The battery is pressed and fixed on one side by a third motor and a pressure plate. Note that: Figure 11 As shown, the battery is placed longitudinally, meaning the cut lines around the battery are aligned longitudinally. Pressure plates press the sides of the battery firmly, leaving the cut lines exposed. The disassembly mechanism is then operated. Holding the casing through the handle, the disassembly blade is aligned with the cut lines on the battery casing. The end with the cutting blade is lifted, allowing the separation plate to insert into the cut seam. The first motor is activated, causing the separation plate to open and separating the battery casing. During this process, the separation plate can be operated to separate different parts of the battery casing, repeating the operation multiple times until one side of the casing is separated. Then, the disassembly blade is operated to cut the structural adhesive between the battery modules. The cutting depth is manually controlled. Once a certain depth is reached, the separation plate is inserted into the cut seam for further separation. The separated components are then sorted and recycled.

[0058] The above-mentioned operation methods disclosed in this invention rely heavily on manual operation. Due to the differences in the thickness of the adhesive layer, the bonding position, and the shell material (aluminum alloy, plastic, etc.) of the encapsulated power battery, it is difficult to accurately identify the cutting position. Moreover, during the cutting process, the adhesive layer buffer and module offset can easily cause cutting deviations, thereby damaging the internal cells. Furthermore, the adhesive layer between adjacent modules is irregularly filled, and the existing automatic separation mechanism cannot adaptively adjust the separation force and angle, which can easily cause safety hazards such as module breakage and electrolyte leakage. Therefore, there is currently no mature fully automatic technology that can achieve efficient, safe, and batch disassembly of this type of battery.

[0059] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0060] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.
