Description

TECHNICAL AREA

[0001] The present invention relates to the technical field of dismantling battery modules and in particular to a dismantling mechanism for a waste battery module. BACKGROUND ON THE STATE OF THE TECHNOLOGY

[0002] Rechargeable batteries generally include nickel-cadmium, nickel-hydrogen, and lithium-ion batteries. Cadmium, in nickel-cadmium batteries, is a heavy metal strictly controlled by environmental protection laws. Organic electrolytes in lithium-ion batteries, alkalis in nickel-cadmium and nickel-hydrogen batteries, and heavy metals such as copper, an auxiliary material used in battery manufacturing, contribute to environmental pollution. Recycling used rechargeable batteries can not only effectively protect the environment but also reuse the recovered metallic materials, thereby preventing resource waste to a certain extent.

[0003] Existing recycling processes for used rechargeable batteries often require first disassembling a battery module and then dismantling and recycling the battery's inner core. However, current methods for disassembling battery modules are mostly manual; that is, after the used battery has been mechanically cut, the battery casing must be manually removed before the battery's inner core can be extracted. This process is cumbersome, time-consuming, and labor-intensive, and the worker's body can easily be injured by the sharp cut in the battery casing or by improper operation of the cutting machine. Therefore, a device capable of automatically disassembling the battery module is urgently needed to overcome these problems.

[0004] CN208706801U discloses an automatic device for removing casings from used batteries, comprising a machine body. A motor is attached to the machine body, and the motor's output shaft is connected via a coupling to a threaded rod. The threaded rod runs parallel to a guide rod. From right to left, the threaded rod and the guide rod successively pass through a casing catch groove A, a core catch groove, and a casing catch groove B. The casing catch groove A, the core catch groove, and the casing catch groove B are located inside the machine body. The threaded rod is driven by the motor. The first and second screws on the threaded rod have opposite thread directions, allowing the first and second screws to move simultaneously in opposite directions.Fastening devices on the movable plates of the first screw and the second screw drive the battery, which has already been cut into two parts, in opposite directions, so that the battery core falls into the core collection groove, while the two parts of the metal casing fall separately into the casing collection groove A and the casing collection groove B.

[0005] US2021167434A1 discloses a device and a method for pretreating batteries. The battery pretreatment device comprises a control mechanism, an automatic feeding mechanism, a transmission mechanism, a current monitoring actuator, a non-destructive testing mechanism, a flexible gripping mechanism, a multi-station operating table, an automatic cutting mechanism, an automatic separation mechanism, and a recovery and dust collection system, each electrically connected to the control mechanism.

[0006] Furthermore, JP2019125444A discloses a cell pack and a method for its manufacture and disassembly. Branko Miloradović et al. disclose a method for disassembling a used battery in an IEEE publication entitled "Challenges in the Automated Disassembly Process of Electric Vehicle Battery Packs".

[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are illustrated in the accompanying drawings. The same or similar reference numerals in the drawings denote identical or similar elements or elements with identical or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to illustrate the present invention, but are not to be understood as limiting the present invention. Design 1:

[0021] As in the Fig. 1, Fig. 2, Fig. 3, Fig. 4 to Fig. As shown in Figure 5, a dismantling mechanism for a used battery module comprises a substrate 1. The substrate 1 is provided with a clamping mechanism 2, a cutting mechanism 3, a storage platform 4, a receiving container 5, a pulling mechanism 6, and a connecting mechanism 7 on an upper section. The clamping mechanism 2 and the cutting mechanism 3 are each located at opposite ends of the upper section of the substrate 1. The storage platform 4 is arranged directly below a clamping part of the clamping mechanism 2, and the storage platform 4 comprises a movable platform 41 and a fixed platform 42, the movable platform 41 being rotatably mounted in a center of the fixed platform 42. A cutting part of the cutting mechanism 3 extends to directly above the movable platform 41 of the storage platform 4.The receiving container 5 comprises a shell collecting frame 51 and an inner core collecting frame 52. The shell collecting frame 51 is located below the clamping mechanism 2 at one end of the stationary platform 42, far from the movable platform 41. The inner core collecting frame 52 is located directly below the movable platform 41. The connecting mechanism 7 comprises a sliding rod 72, a sliding block 73, a connecting rack 74, and a gearbox 75. The sliding rod 72 is arranged between the inner core collecting frame 52 and a fixed end of the cutting mechanism 3 along a longitudinal direction of the substrate 1.

[0022] The sliding block 73 and the connecting rack 74 are both slidably mounted on the sliding rod 72. The connecting rack 74 is located between the inner core receiving frame 52 and the sliding block 73, and a spring 71 is fitted outside the sliding rod 72 between the sliding block 73 and the fixed end of the cutting mechanism 3. The sliding block 73 is movably provided with two connecting arms 731 to connect the clamping part of the clamping mechanism 2 to an upper section.The gearbox 75 is attached to a pivot shaft of the movable platform 41 by a fastening rod, and the gearbox 75 is provided with an upper slide bar and a lower slide bar, the two slide bars being connected by a gear in the gearbox 75, one end of a slide bar being connected to the connecting rack 74, so that the connecting rack 74 is able to force the slide bar to drive the gear in the gearbox 75 to rotate as it slides and is displaced along the slide bar 72, and to connect the movable platform 41 to rotate about a pivot shaft thereof.

[0023] The pulling mechanism 6 is attached at one end of the clamping mechanism 2, far from the storage platform 4. One end of a pulling link of the pulling mechanism 6 is connected to the cutting mechanism 3, and the other end of the pulling link is connected to the sliding block clamping mechanism 73. The clamping part of the clamping mechanism 2 can clamp and fix a battery to be disassembled on the storage platform 4, such that a cutting path of the cutting part of the cutting mechanism 3 is located at a waistline of a multitude of cores of the battery to be disassembled. The cutting part of the cutting mechanism 3 can cut along the waistline of the cores during the movement process, allowing the multitude of inner cores to fall naturally onto the movable platform 41 after a casing of the battery has been disassembled. Since the pulling link of the pulling mechanism 6 is connected to the cutting mechanism 3 and the sliding block 73, the sliding block 73 canWhen the cutting part of the cutting mechanism 3 is adjusted to a suitable position and after the tension member between the cutting mechanism 3 and the sliding block 73 is tensioned, the movable cutting part of the cutting mechanism 3 (the cutting part of the cutting mechanism 3 from one end of the storage platform 4 to the fixed end of the cutting mechanism 3) moves along the sliding rod 72 to one end of the storage platform 4 under the action of the tension member. In this case, the connecting arm 731 can force the clamping part of the clamping mechanism 2 to move from the movable platform 41 to the fixed platform 42, so that the old battery fixed in the clamping part of the clamping mechanism 2 can be pulled on both sides along a notched opening in the casing to force the casing of the battery open on both sides, so that the inner core of the battery can fall onto the movable platform 41.to separate from the battery casing. When moving towards the connecting rack 74, the sliding block 73 can force the connecting rack 74 to slide along the sliding rod 72, so that the sliding rod at its lower end, which is located in the gearbox 75, moves and drives the gear inside the gearbox 75 to drive and connect the sliding rod at its lower end in the gearbox 75 to move, so that the movable platform 41 can rotate about its pivot shaft under the action of the gear in the gearbox 75, and so that the movable platform 41 can rotate about its pivot shaft under the action of the gear in the gearbox 75, so that the inner core of the battery, which falls onto the movable platform 41, can fall together with the rotated movable platform 41 into the inner core receiving frame 52, and the casing of the battery, which is fixed to the clamping part of the clamping mechanism 2,can move to the casing collection frame 51 and fall into the casing collection frame 51 for collection along with the release of the clamping part of the clamping mechanism 2. In this way, the battery casing and the inner core of the battery can be systematically collected after the old battery has been dismantled by the device, which simplifies the complicated process caused by manually removing the casing from the battery, improves the dismantling rate of the battery module and avoids the risk of physical injury caused by manually removing the casing from the battery.

[0024] As in the Fig. 1, Fig. 2, Fig. 3 to Fig. As shown in Figure 4, the clamping mechanism 2 in this embodiment comprises a base 21, a first motor 22, a screw shaft 23, two sliding pieces 24, two support racks 25, and two clamping rods 27. The base 21 is arranged along a width direction of the substrate 1. The first motor 22 is attached to one end of the base 21. The screw shaft 23 is arranged inside the base 21 along a direction of arrangement of the base 21, and one end of the screw shaft 23 is connected to an output shaft of the first motor 22. The two sliding pieces 24 are both arranged outside the screw shaft 23 and are slidably connected to the base 21, so that the screw shaft 23 is able to drive the two sliding pieces 24 so that they move synchronously with a center of the base 21 or with two ends of the base 21 during rotation.The two support racks 25 are each attached to the upper sections of the two sliding pieces 24. Both support racks 25 have a sector structure and are arranged symmetrically around a central axis along the length of the substrate 1. The two clamping rods 27 are each attached above the two support racks 25, and each clamping rod 27 is able to move along an arcuate edge of the support rack 25 below the clamping rod. One end of the clamping rod 27 is movably connected to the connecting arm 731, and the clamping rod 27 is provided with a movable clamping plate 26 on one side near the cutting mechanism 3, so that the clamping rod 27 forms the clamping part of the clamping mechanism 2, which is used to fix and clamp the old battery. When rotated, the first motor 22 can rotate the screw shaft 23.Under the action of the screw shaft 23, the two sliding pieces 24 move synchronously to the center of the base 21 or to both ends of the base 21 along an arrangement direction of the base 21 to set a distance between the two clamping rods 27, and then the clamping part of the clamping mechanism 2 is formed by the two clamping rods 27 to clamp and fix old batteries of different sizes.In this embodiment, the clamping rod 27 is provided with a drive element (not shown in the figure) for adjusting the distance of the movable clamping plate 26, so that the movable clamping plate 26 can also be adaptively adjusted according to the size of the casing of the old battery, so that when the old battery is fixed between the two clamping rods 27, the other two sides of the battery can be clamped onto the clamping rod 27 by the movable clamping plate 26 and the clamping stability of the battery on the clamping rod 27 can be improved, so that the old battery can be clamped stably on the storage platform 4, thus ensuring that the battery cannot slip and become misaligned when it is cut open by the cutting mechanism 3, and ensuring the stable dismantling of the battery.

[0025] In this embodiment, each support rack 25 is provided with a guide groove 251 on the arcuate edge, and each clamping rod 27 is provided with a guide block 271 which fits together with the guide groove 251 at a lower part, so that the clamping rod 27 is able to slide and move along the arcuate edge of the support rack 25 through the fit between the guide block 271 and the guide groove 251.The support rack 25 can be used as a support element to support the clamping rod 27 and also allows the clamping rod 27 to slide along the arcuate edge of the support rack 25 when the clamping rod 27 is forced to do so by the connecting arm 731. This ensures that the clamping rod 27 can exert an outward tensile force on a cut in the battery casing during the battery module disassembly process, causing the battery casing to be ripped open on both sides along the cut direction to separate the battery's inner core from the battery casing. The arrangement of the guide groove 251 and the guide block 271 can improve the connection between the support rack 25 and the clamping rod 27 and ensure that the clamping rod 27 can slide stably along the arcuate edge of the support rack 25.

[0026] As in Fig. 1 and Fig. As shown in Figure 4, in this embodiment the casing collection frame 51 is located directly below the sector groove of the support rack 25. The clamping rod 27 slides and moves along the arcuate edge of the support rack 25, and a clamping gap of the movable clamping plate 26 is always located in an opening area of ​​the casing collection frame 51. In this specific position, the casing collection frame 51 can always hold the battery casing in the center of the movable clamping plate 26 within the opening area of ​​the casing collection frame 51 when the clamping rod 27 slides and moves along the arcuate edge of the support rack 25, so that after the movable clamping plate 26 is released, the battery casing can fall directly into the casing collection frame 51 for centralized collection.

[0027] As in Fig. 1 and Fig. As shown in Figure 2, the cutting mechanism 3 in this embodiment comprises a second motor 31, a protective cover 32, a fixed plate 33, a blade 34, and a telescopic rod 35. The telescopic rod 35 is connected to the substrate 1, the fixed plate 33 is attached to an upper end of the telescopic rod 35, and the fixed plate 33 is provided with a slide at a lower section of an end furthest from the telescopic rod 35, and the protective cover 32 is arranged to slide in the slide. The second motor 31 is attached to an outer surface of one end of the protective cover 32. The blade 34 is rotatably arranged within the protective cover 32 and is connected to an output shaft of the second motor 31, such that the blade 34 forms the cutting part of the cutting mechanism 3.The telescopic rod 35 can be either an electric push rod, a hydraulic cylinder, or an air cylinder, preferably the hydraulic cylinder, so that the telescopic rod 35 can lift the fixed plate 33, thereby changing the actual cutting height of the blade 34 to meet the cutting requirements of different-sized used batteries. The protective cover 32 can move along the sliding track of the fixed plate 33, so that when the second motor 31 drives the blade 34 to rotate, the protective cover 32 drives the blade 34 to move, and a cutting line is formed by the movement of the blade 34 to cut the casing of the used battery.

[0028] In this embodiment, the protective cover 32 is provided with an opening at a lower end, and the protective cover 32 is provided with a sliding block 321 at an upper end, which fits together with the sliding track. The opening of the protective cover 32 serves to expose the blade 34, so that the blade 34 can have a certain degree of protection, damage to the blade 34 from flying fragments during cutting is reduced, and it is ensured that the blade 34 is positioned sufficiently to make contact with the battery casing so that the casing of the battery is cut open by the exposed blade 34.

[0029] As in Fig. 2 and Fig. As shown in Figure 3, the pulling mechanism 6 in this embodiment comprises a mounting plate 61, two first guide wheels 62, two second guide wheels 63, a pull cable 64, and a tensioning wheel 65. The mounting plate 61 is connected to a central section of the substrate 1 on a side of the base 21 that is farther away from the support rod 25. The two first guide wheels 62 are each attached to the upper and lower ends of a side of the mounting plate 61 facing the base 21. The two second guide wheels 63 are attached directly below the central sections of the two support racks 25. The tensioning wheel 65 is attached to one end of the protective cover 32.One end of the pull rope 64 is connected to the tension wheel 65, and the other end of the pull rope passes successively over the two first guide wheels 62 and is split into two ropes, each extending to the two second guide wheels 63 and then extending from the two second guide wheels 63 to both sides of the sliding block 73 and being connected to the sliding block 73, so that the pull rope 64 is able to form a pull link connected to the cutting mechanism 3 and the sliding block 73.The tensioning wheel 65 can tighten the pull rope 64 after the clamping part of the clamping mechanism 2 and the cutting part of the cutting mechanism 3 have been adjusted into the correct position, so that the fixed plate 33, the sliding block 73, the connecting arm 731 and the clamping rod 27 are in a tensioned state, ensuring that the protective cover 32 of the cutting mechanism 3 can pull the pull rope 64 and then pull the sliding block 73 to move on the sliding rod 72, so that an angle of the connecting arm 731 can be changed as the sliding block 73 moves, so that the connecting arm 731 can force the clamping rod 27 to rotate, thereby realizing the movement of the clamping rod 27 along the arcuate edge of the support rod 25.The first guide wheel 62 and the second guide wheel 63 can be used to guide the pull rope 64, to ensure that the pull rope 64 can be stably connected between the cutting mechanism 3 and the sliding block 73, and to ensure that the pull rope 64 can move stably.

[0030] In this embodiment, the sliding block 73 is provided with connecting rods 732 to connect the two ropes of the pull rope 64 on both sides. The connecting rod 732 ensures that the sliding block 73 is stably connected to the two ropes of the pull rope 64 and allows the pull rope 64 to pull the sliding block 73 to move when the protective cover 32 of the cutting mechanism 3 moves.

[0031] As in Fig. As shown in Figure 2, in this embodiment the slide rod 72 is provided with at least one limiting groove 721 for limiting the sliding path of the connecting rod 74 on an outer side wall. Preferably, there are three limiting grooves 721, and the three limiting grooves 721 are arranged at equal intervals on the outer side wall of the slide rod 72, so that the connecting rack 74 can be slidably connected to the slide rod 72 through the limiting grooves 721 and the stroke of the connecting rack 74 is limited (i.e., the rotation angle of the movable platform 41 is limited).

[0032] As in Fig. 4 and Fig.As shown in Figure 5, the gearbox 75 in this embodiment is internally provided with a first gear 751, a first guide rod 752, a second gear 753, a second guide rod 754, a third gear 755, and a fourth gear 756. The first gear 751 and the third gear 755 are arranged on the same rotating shaft. The second gear 753 is rotatably arranged below the first gear 751. The fourth gear 756 is arranged on the rotating shaft of the movable platform 41 and meshes with the third gear 755.The first sliding rod 752 and the second sliding rod 754 form upper and lower sliding rods of the gearbox 75; the first sliding rod 752 is provided with a toothed socket that meshes with the first gear 751 at an upper end, and the first sliding rod 752 is provided with a toothed socket that meshes with the second gear 753 at a lower end; the second sliding rod 754 is provided with a toothed socket that meshes with the second gear 753 at an upper end, and one end of the second sliding rod 754 is connected to the connecting rack 74.The connecting rack 74 can be magnetically connected to the sliding block 73, and an elastic force of the spring 71 is greater than a magnetic attraction force of the connecting rack 74 and the sliding block 73, so that the sliding block 73 can be magnetically fixed after being attached to the connecting rack 74, so that the sliding block 73 can force the connecting rack 74 to move synchronously as it moves to one end of the movable platform 41, and after the tensioning wheel 65 loosens the pull cable 64 to reset the sliding block 73 under the action of the spring 71, the connecting rack 74 can be reset synchronously under the action of the sliding block 73 until the connecting rack 74 slides to the rear end of a limiting groove 721 and then separates from the sliding block 73, thereby realizing the complete reset of the sliding block 73 and the connecting rack 74.When the sliding block 73 forces the connecting rack 74 to move to one end of the movable platform 41, the second sliding bar 754 moves in the same direction as the connecting rack 74, and the moving second sliding bar 754 forces the second gear 753 to rotate, so that the second gear 753 drives the first sliding bar 752 to move to the fixed end of the cutting mechanism 3, causing the first gear 751 and the third gear 755 to rotate synchronously. In this way, the rotating third gear 755 engages with the fourth gear 756 to rotate, causing the rotating shaft of the movable platform 41 to rotate downwards, and the inner core of the battery, falling onto the movable platform 41, can automatically fall into the inner core collection frame 52 for centralized collection.

[0033] In summary, according to the disassembly mechanism for the old battery module provided by the present invention, by including the clamping mechanism 2, the cutting mechanism 3, the storage platform 4, the receiving container 5, the pulling mechanism 6 and the connecting mechanism 7, the clamping part of the clamping mechanism 2 can clamp and fix the battery to be disassembled on the storage platform 4, and the casing of the battery can be cut open and disassembled by the cutting part of the cutting mechanism 3.When the cutting part of the cutting mechanism 3 moves and cuts, the sliding block 73 of the connecting mechanism 7 can be pulled by the pulling mechanism 6 to move to one end of the storage platform 4, and then the clamping part of the clamping mechanism 2 can be forced to move from the movable platform 41 to the stationary platform 42 by the connecting arm 731 on the upper section of the sliding block 73, so that the old battery, which is fixed in the clamping part of the clamping mechanism 2, can be pulled and broken open from both sides along the notched opening slot on the casing, and the inner core of the battery can fall freely onto the movable platform 41, thereby separating it from the casing of the battery.During the movement, the sliding block 73 forces the connecting rack 74 to drive the gear in the gearbox 75 to rotate, so that the movable platform 41 can rotate about its rotating shaft under the action of the gear in the gearbox 75, so that the inner core of the battery, which falls onto the movable platform 41, can fall into the inner core receiving frame 52 together with the rotated movable platform 41, and the casing of the battery, which is fixed to the clamping part of the clamping mechanism 2, can move to and fall into the casing receiving frame 51.Once the old battery has been dismantled by the facility, the battery casing and the inner core of the battery can be systematically collected, simplifying the complicated process caused by manually removing the casing from the battery, improving the dismantling rate of the battery module, and avoiding the risk of physical injury caused by manually removing the casing from the battery.
