[0019] With such a configuration, the movable door can push the fire extinguishing medium into the fire extinguishing chamber, thereby extinguishing the fire of the batteries in the fire extinguishing chamber. Alternatively, the movable door can move in a direction away from the fire extinguishing chamber, thereby making it possible to keep the movable door away from the fire extinguishing chamber, thereby facilitating the storage of the fire extinguishing medium on the side of the movable door facing the fire extinguishing chamber.

[0020] In one embodiment, the fire extinguishing cavity is provided with a pull-out opening, a pull-out box is provided in the fire extinguishing cavity, the pull-out box is provided with an inlet communicated with the blanking opening, and the pull-out box is slidably arranged at the pull-out opening.

[0021] With such an arrangement, the battery after thermal runaway can fall into the drawer box of the fire extinguishing chamber, and the drawer box can be slid through the drawer opening to be drawn out, thereby facilitating the user to take out the battery in the drawer box.

[0054] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0055] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0056] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0057] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0058] For example, some power batteries are cylindrical batteries, and some cylindrical batteries use steel shells with high hardness, which can effectively suppress the risks brought by battery expansion. However, when testing and analyzing cylindrical batteries, it is necessary to non-destructively disassemble the fully charged steel shell cylindrical batteries, and foreign matter such as impurities should not be introduced during the disassembly process. In the related art, cylindrical batteries can only be disassembled manually, that is, manually cut a hole with an art knife, and then roll open the top cover with pliers. Due to the high hardness of the steel shell, manual cutting with a knife is extremely difficult and inefficient. If the strength is not properly controlled, it is easy to scratch the pole piece, resulting in a short circuit and thermal runaway. However, there is no emergency response to battery thermal runaway in the related art, which leads to some adverse risks.

[0059] The batteries in the present invention include but are not limited to cylindrical batteries, rectangular batteries, etc.

[0060] In order to reduce the adverse risk caused by thermal runaway of the battery during the battery disassembly process, the utility model proposes a battery disassembly device.

[0061] Please refer to Figures 1 to 3 In one embodiment of the utility model, the battery disassembly device includes a base 100, a clamping mechanism 200 and a fire extinguishing box 300; a cutting station is provided on the base 100, and the cutting station is provided with a blanking port 111; the clamping mechanism 200 is provided at the cutting station and forms an escape space 201 for clamping or loosening the battery, and the escape space 201 is connected to the blanking port 111; the fire extinguishing box 300 is provided on one side of the base 100 and is connected to the blanking port 111.

[0062] The base 100 is a reference component for disassembling the battery.

[0063] The cutting station refers to a station for cutting the battery. It is understandable that in the present invention, the cutting station is also provided with a cutting mechanism 700, which may include a cutter or a laser, and may also include a lifting mechanism for driving the cutter or the laser to move up and down, so as to achieve the cutting effect on the battery shell. The cutting mechanism 700 may be arranged above, in front of, or behind the clamping mechanism 200, as long as it can achieve the cutting effect on the battery shell.

[0064] The clamping mechanism 200 refers to a mechanism for clamping or loosening the battery. It is understandable that the clamping mechanism 200 can clamp the opposite ends of the battery. In order to clamp or loosen the opposite ends of the battery, the clamping mechanism 200 usually includes two clamping members arranged opposite to each other, and there is a certain distance between the two clamping members to form an escape space 201, so as to facilitate the placement of the battery in the escape space 201. Alternatively, the clamping mechanism 200 can also clamp one end of the battery and a position close to the middle. In order to clamp or loosen one end of the battery, the clamping mechanism 200 can only include one clamping member, which can clamp one end of the battery and a position close to the middle, and itself forms an escape space 201, and the escape space 201 is used to install the battery to clamp or allow the battery to be detached.

[0065] The drop port 111 refers to an opening for the battery to fall into the fire extinguisher box 300. The size of the drop port 111 is not less than the size of the battery, so that the battery can smoothly pass through the drop port 111 into the fire extinguisher box 300. The shape of the drop port 111 can be rectangular, circular or other shapes. By setting the drop port 111 at the cutting station of the base 100, and the drop port 111 is connected to the escape space 201 of the clamping mechanism 200 for clamping or releasing the battery, the battery can fall directly from the escape space 201 to the drop port 111 after thermal runaway occurs, and fall into the fire extinguisher box 300 through the drop port 111.

[0066] The fire extinguishing box 300 refers to a box structure used to extinguish the fire of the battery when the battery has thermal runaway. The fire extinguishing box 300 can be made of metal or other fireproof materials. The shape of the fire extinguishing box 300 can be a rectangular parallelepiped, a cube, a cylinder or other irregularly shaped boxes. In order to allow the battery to fall naturally into the fire extinguishing box 300, the fire extinguishing box 300 is arranged below the base 100 so that the drop port 111 is connected to the escape space 201 formed by the clamping mechanism 200. It is understandable that a fire extinguishing medium can be provided in the fire extinguishing box 300 to cover the battery after thermal runaway that falls through the drop port 111, and then extinguish the battery in thermal runaway. Among them, the fire extinguishing medium can be sand, carbon dioxide, dry powder or water.

[0067] In order to transport the fire extinguishing medium into the fire extinguishing box 300, the user can transport the fire extinguishing medium through the feed opening 111, or through other openings on the fire extinguishing box 300 that are different from the feed opening 111. It is understandable that different fire extinguishing media can be transported in different ways. For example, when the fire extinguishing medium is sand, water or other media, gravity can be used to transport the fire extinguishing medium into the fire extinguishing box 300. Specifically, an inclined feed opening can be provided on the side wall of the fire extinguishing box 300, and the fire extinguishing medium can be fed into the fire extinguishing box 300 through the feed opening, so that the fire extinguishing medium covers the thermal runaway battery in the fire extinguishing box 300 and achieves a fire extinguishing effect on the battery. Of course, this can reduce the process of opening a feed opening on the side wall of the fire extinguishing box 300. When the fire extinguishing medium is a liquid such as water, the fire extinguishing medium can also be directly dropped through the discharge port 111. The water source can be connected through one end of the pipeline, and the other end can be connected to the fire extinguishing box 300 to achieve the effect of filling the fire extinguishing medium into the fire extinguishing box 300 to cover the battery in thermal runaway.

[0068] The technical solution of the utility model can clamp the battery through the clamping mechanism 200 by setting the clamping mechanism 200 at the cutting station so that the cutting mechanism 700 on the cutting station can stably cut the battery shell. By setting the blanking port 111 at the cutting station of the base 100, and the clamping mechanism 200 forms an escape space 201 for clamping or releasing the battery, the escape space 201 is connected to the blanking port 111, and the fire extinguishing box 300 is connected to the blanking port 111, so that when the battery is in a thermal runaway state, the clamping mechanism 200 can also release the battery, and then the battery can enter the fire extinguishing box 300 through the blanking port 111, so that the battery can be extinguished in the fire extinguishing box 300, reducing the adverse risks caused by thermal runaway of the battery.

[0069] Please refer to Figure 1 and Figure 2 In one embodiment of the present utility model, the fire extinguishing box 300 has a fire extinguishing chamber 310 and a storage chamber 320, the fire extinguishing chamber 310 is connected to the material discharge port 111, and the storage chamber 320 can be connected to the fire extinguishing box 300.

[0070] The fire extinguishing cavity 310 is a cavity for extinguishing a fire on a battery, that is, the battery enters the fire extinguishing cavity 310 of the fire extinguishing box 300 to be extinguished. The cross-sectional shape of the fire extinguishing cavity 310 can be rectangular, circular, trapezoidal or other shapes.

[0071] The storage cavity 320 refers to a cavity for storing the fire extinguishing medium. The cross-sectional area of ​​the storage cavity 320 may be rectangular, circular, trapezoidal or other shapes. The volumes of the fire extinguishing cavity 310 and the storage cavity 320 may be equal or unequal. The shape of the fire extinguishing cavity 310 and the shape of the storage cavity 320 may be the same or different.

[0072] By connecting the fire extinguishing chamber 310 to the discharge port 111, the battery can enter the fire extinguishing chamber 310 to extinguish the fire after being released by the clamping mechanism 200. By providing a storage chamber 320, the storage chamber 320 can be connected to the fire extinguishing chamber 310, and after the battery enters the fire extinguishing chamber 310, the storage chamber 320 can be connected to the fire extinguishing chamber 310 so that the fire extinguishing medium in the storage chamber 320 can enter the fire extinguishing chamber 310 to cover the battery, thereby achieving an effective fire extinguishing effect on the battery.

[0073] Please refer to Figure 1 and Figure 2 In one embodiment of the present invention, the bottom wall of the storage chamber 320 is arranged higher than the bottom wall of the fire extinguishing chamber 310 .

[0074] The bottom wall of the storage cavity 320 refers to the wall of the storage cavity 320 closest to the ground when the battery disassembling device is in normal working state. The bottom wall of the storage cavity 320 can be a flat surface, a stepped surface, or a sloped surface.

[0075] The bottom wall of the fire extinguishing chamber 310 refers to the wall of the fire extinguishing chamber 310 closest to the ground when the battery disassembling device is in normal working state. The bottom wall of the storage chamber 320 can be a flat surface, a stepped surface, or a sloped surface.

[0076] By setting the bottom wall of the storage chamber 320 higher than the bottom wall of the fire extinguishing chamber 310, the fire extinguishing medium stored in the storage chamber 320 can fall from the storage chamber 320 into the fire extinguishing chamber 310 under the action of gravity to extinguish the battery. At the same time, such a setting makes the storage chamber 320 suitable for storing solid granular fire extinguishing media such as sand.

[0077] Please refer to Figure 1 and Figure 2 A movable door 330 is provided in the fire extinguishing box 300, and the movable door 330 has a first state and a second state. When the movable door 330 is in the first state, the fire extinguishing chamber 310 is connected with the storage chamber 320, and the fire extinguishing medium in the storage chamber 320 enters the fire extinguishing chamber 310; when the movable door 330 is in the second state, the fire extinguishing medium in the storage chamber 320 is in a static state.

[0078] The movable door 330 refers to a movable component. The movable door 330 can be used as a valve component or a driving component. When the movable door 330 is used as a valve component, it can be used as a valve component to connect or isolate the storage chamber 320 with the fire extinguishing chamber 310; specifically, when it is active, it has a first state of opening the storage chamber 320 and connecting the storage chamber 320 with the fire extinguishing chamber 310, and a second state of blocking the storage chamber 320 to prevent the fire extinguishing medium in the storage chamber 320 from flowing into the fire extinguishing chamber 310. The movable door 330 can be slidably arranged in the fire extinguishing box 300, for example, the movable door 330 can slide in the direction perpendicular to the fire extinguishing chamber 310 to the storage chamber 320, so that the movable door 330 can have a first state of connecting the fire extinguishing chamber 310 with the storage chamber 320 and a second state of isolating the fire extinguishing chamber 310 from the storage chamber 320. Alternatively, the movable door 330 can be rotatably arranged in the fire extinguishing box 300, as long as it can achieve the above-mentioned first state and second state during the activity. There may be one or at least two movable doors 330. When there are at least two movable doors 330, the two movable doors 330 may be symmetrically arranged in the direction perpendicular to the fire extinguishing chamber 310 to the storage chamber 320, or may be arranged in parallel in the extending direction from the storage chamber 320 to the fire extinguishing chamber 310.

[0079] When the movable door 330 is used as a driving component, it can be used as a push plate to push the fire extinguishing medium in the storage chamber 320 to move to the fire extinguishing chamber 310; specifically, in this scenario, it is ensured that the storage chamber 320 and the fire extinguishing chamber 310 are always in a connected state, and the fire extinguishing medium in the storage chamber 320 is in a static state without external force, then the state of the movable door 330 when moving in the direction close to the fire extinguishing chamber 310 is the first state, at this time, the fire extinguishing medium in the storage chamber 320 can enter the fire extinguishing chamber under the pushing action of the movable door 330; when the movable door 330 is stationary, it is in the second state, at this time, the fire extinguishing medium in the storage chamber 320 cannot automatically enter the fire extinguishing chamber 310.

[0080] By providing the above-mentioned movable door 330 in the fire extinguishing box 300 , it is possible to flexibly control whether the fire extinguishing medium in the storage cavity 320 enters the fire extinguishing cavity 310 by controlling the state of the movable door 330 .

[0081] Please refer to Figure 1 and Figure 2 Furthermore, the bottom wall of the storage chamber 320 is inclined downward from the side away from the fire extinguishing chamber 310 to the side close to the fire extinguishing chamber 310; when the movable door 330 is in the first state, the fire extinguishing chamber 310 is connected to the storage chamber 320, and when the movable door 330 is in the second state, the storage chamber 320 and the fire extinguishing chamber 310 are isolated from each other.

[0082] By tilting the bottom wall of the storage chamber 320 downward from the side away from the fire extinguishing chamber 310, the fire extinguishing medium in the storage chamber 320 can slide toward the fire extinguishing chamber 310, so that more fire extinguishing medium can be closer to the storage chamber 320. By setting a movable door 330 in the fire extinguishing box 300, the movable door 330 has a first state and a second state, and the movable door 330 is in the first state, the fire extinguishing chamber 310 is connected with the storage chamber 320, so that the fire extinguishing medium in the storage chamber 320 can slide directly into the fire extinguishing chamber 310, thereby achieving a good fire extinguishing effect on the battery. By placing the movable door 330 in the second state, the fire extinguishing chamber 310 and the storage chamber 320 are isolated from each other, so that the risk of the fire extinguishing medium in the storage chamber 320 sliding into the fire extinguishing chamber 310 when the battery does not fall into the fire extinguishing box 300 can be avoided.

[0083] In one embodiment of the utility model, the movable door 330 includes a first movable sub-door and a second movable sub-door, and the first movable sub-door and the second movable sub-door are both movably arranged in the fire extinguishing box 300. The first movable sub-door and the second movable sub-door can be close to each other and isolate the fire extinguishing chamber 310 from the storage chamber 320; or the first movable sub-door and the second movable sub-door can be far away from each other to make the fire extinguishing chamber 310 and the storage chamber 320 connected to each other.

[0084] The first movable sub-door refers to a part of the door structure used to block the communication passage between the fire extinguishing chamber 310 and the storage chamber 320. The first movable sub-door can be slidably disposed in the fire extinguishing box 300, and can also be rotatably disposed in the fire extinguishing box 300.

[0085] The second movable sub-door refers to a part of the door structure used to block the communication passage between the fire extinguishing chamber 310 and the storage chamber 320 together with the first movable sub-door. The second movable sub-door can be slidably arranged in the fire extinguishing box 300, or can be rotatably arranged in the fire extinguishing box 300. For example, the first movable sub-door and the second movable sub-door are both slidably arranged in the fire extinguishing box 300, and the movement directions of the first movable sub-door and the second movable sub-door are both perpendicular to the direction from the fire extinguishing chamber 310 to the storage chamber 320, and the movement directions of the first movable sub-door and the second movable sub-door are opposite. Alternatively, the first movable sub-door and the second movable sub-door are both rotatably arranged in the fire extinguishing box 300, and the first movable sub-door and the second movable sub-door form a rotating double-door structure. Of course, in other examples, one of the first movable sub-door and the second movable sub-door can be slidably disposed in the fire extinguishing box 300, and the other one can be rotatably disposed in the fire extinguishing box 300, as long as the first movable sub-door and the second movable sub-door can be brought close to each other and the fire extinguishing chamber 310 and the storage chamber 320 can be isolated from each other, and the first movable sub-door and the second movable sub-door can be moved away from each other and the fire extinguishing chamber 310 and the storage chamber 320 can be connected to each other.

[0086] By movably arranging the first movable sub-door and the second movable sub-door in the fire extinguishing box 300, and the first movable sub-door and the second movable sub-door are close to each other and can isolate the fire extinguishing chamber 310 and the storage chamber 320 from each other, the movement path of the first movable sub-door and / or the second movable sub-door can be reduced, so that the fire extinguishing chamber 310 and the storage chamber 320 can be connected in time, and the fire extinguishing medium can be delivered into the fire extinguishing chamber 310 in time, thereby improving the fire extinguishing efficiency.

[0087] In one embodiment of the present invention, the bottom wall of the storage chamber 320 is horizontally arranged; the movable door 330 is arranged in the storage chamber 320, and the movable door 330 is slidably arranged in the fire extinguishing chamber 310, and can move toward the direction close to the fire extinguishing chamber 310 or move away from the fire extinguishing chamber 310.

[0088] The bottom wall of the storage cavity 320 is arranged horizontally, which means that the bottom wall of the storage cavity 320 is parallel to the horizontal plane.

[0089] By sliding the movable door 330 in the fire extinguishing chamber 310 and moving it toward the fire extinguishing chamber 310, the movable door 330 can push the fire extinguishing medium into the fire extinguishing chamber 310, thereby extinguishing the fire of the batteries in the fire extinguishing chamber 310. Alternatively, the movable door 330 can move in a direction away from the fire extinguishing chamber 310, thereby allowing the movable door 330 to be away from the fire extinguishing chamber 310, thereby facilitating the storage of the fire extinguishing medium on the side of the movable door 330 facing the fire extinguishing chamber 310.

[0090] Please refer to Figure 1 and Figure 2 In one embodiment of the present invention, a first sensor 400 is installed at the material drop opening 111 , and the first sensor 400 is electrically connected to the movable door 330 .

[0091] The first sensor 400 is used to sense whether a battery passes through, and then when a battery passes through, it can be determined that the battery enters the fire extinguisher box 300, and the signal is transmitted to other execution components. The first sensor 400 can be a photoelectric sensor or a mechanical trigger sensor.

[0092] By installing the first sensor 400 at the drop opening 111, the first sensor 400 can sense whether the battery enters the fire extinguishing box 300. By electrically connecting the first sensor 400 with the movable door 330, when the first sensor 400 senses that the battery enters the fire extinguishing box 300 through the drop opening 111, the signal is transmitted to the controller, and then the controller controls the movable door 330 to be in the first state, so that the fire extinguishing chamber 310 is connected with the storage chamber 320, so that the fire extinguishing medium in the storage chamber 320 enters the fire extinguishing chamber 310 to cover the battery, thereby automatically achieving the effect of effectively extinguishing the battery in thermal runaway.

[0093] Please refer to Figure 1 and Figure 2 In one embodiment of the utility model, the fire extinguishing chamber 310 is provided with a pull-out opening 311 , a pull-out box 312 is provided in the fire extinguishing chamber 310 , the pull-out box 312 is provided with an entrance connected to the blanking opening 111 , and the pull-out box 312 is slidably arranged at the pull-out opening 311 .

[0094] The drawer box 312 refers to a drawable box body. The opening of the drawer box 312 can be rectangular or circular.

[0095] The drawer opening 311 refers to an opening for the drawer box 312 to be drawn out or pushed into the fire extinguishing chamber 310 . The shape of the opening can be adapted to the shape of the drawer box 312 , thereby ensuring that the fire extinguishing chamber 310 has good sealing performance.

[0096] With such arrangement, the battery after thermal runaway can fall into the drawer box 312 of the fire extinguishing chamber 310 , and the drawer box 312 can be slid through the drawer opening 311 to be drawn out, thereby facilitating the user to take out the battery in the drawer box 312 .

[0097] Please refer to Figure 1 and Figure 2 In one embodiment of the utility model, the clamping mechanism 200 includes a first clamp 210, a second clamp 220 and a translation mechanism 230; the first clamp 210 is provided with a plurality of movable jaws 211, the plurality of movable jaws 211 can gather together or separate from each other, and the plurality of movable jaws 211 jointly clamp one end of the battery; the second clamp 220 is arranged opposite to the first clamp 210, and clamps the other end of the battery; an avoidance space 201 is formed between the first clamp 210 and the second clamp 220; the translation mechanism 230 is drivingly connected to the first clamp 210 or the second clamp 220, so that the first clamp 210 and the second clamp 220 are close to or away from each other.

[0098] The first clamp 210 refers to a clamp used to clamp or release one end of a battery. The first clamp 210 is provided with a plurality of movable jaws 211, and the plurality of movable jaws 211 can be gathered together or separated, so that when the plurality of movable jaws 211 are gathered together, they can clamp one end of the battery together, and when the plurality of movable jaws 211 are separated from each other, they can release one end of the battery. In order to enable the plurality of movable jaws 211 to be gathered together or separated, the first clamp 210 can also include a main body, and the plurality of movable jaws 211 are slidably arranged on the main body and arranged in a circular array. An elastic member can be connected between the movable jaw 211 and the main body, one end of the elastic member is connected to the main body, and the other end is connected to the jaw, and the elastic expansion and contraction direction of the elastic member is consistent with the sliding direction of the movable jaw 211 connected to the elastic member, so that the effect of the plurality of movable jaws 211 gathering together can be automatically achieved under the action of the elastic member. Alternatively, the first clamp 210 can include a plurality of cylinders, and the plurality of cylinders respectively drive the plurality of movable jaws 211 to gather together or separate.

[0099] The second clamp 220 refers to a clamp used to clamp or loosen the end of the battery away from the first clamp 210. The second clamp 220 can be configured to have the same structure as the first clamp 210, or the second clamp 220 can have a different structure from the first clamp 210. For example, the number of movable jaws 211 in the first clamp 210 is different from the number of movable jaws 211 in the second clamp 220. Alternatively, the second clamp 220 may include only one elastic insertion port, and the end of the battery away from the first clamp 210 can be inserted into the insertion port of the second clamp 220.

[0100] The translation mechanism 230 refers to a mechanism that can drive the first clamp 210 to move in a direction close to or away from the second clamp 220, or a mechanism that can drive the second clamp 220 to move in a direction close to or away from the first clamp 210, or a mechanism that can simultaneously drive the first clamp 210 and the second clamp 220 to move closer to or away from each other. The translation mechanism 230 drives the first clamp 210 in a direction close to or away from the second clamp 220 as an example for explanation. Specifically, the translation mechanism 230 can be a cylinder or a hydraulic cylinder, wherein the cylinder or the hydraulic cylinder can be directly connected to the first clamp 210 in a transmission connection. Alternatively, the translation mechanism 230 includes a motor, a gear and a rack, the gear is connected to the motor in a transmission connection, the rack is meshed with the gear and extends in a direction from the first clamp 210 to the second clamp 220, and the rack is connected to the first clamp 210. Alternatively, the translation mechanism 230 includes a motor, a driving pulley, a driven pulley and a synchronous belt, the driving pulley is transmission-connected to the motor, the driven pulley is arranged opposite to the driving pulley, and the two ends of the synchronous belt are respectively mounted on the driving pulley and the driven pulley, and the first clamp 210 is connected to the synchronous belt.

[0101] By setting a first clamp 210 and a second clamp 220, and the first clamp 210 includes a plurality of movable jaws 211, the plurality of movable jaws 211 can gather together or separate and are used to jointly clamp one end of the battery, and the second clamp 220 is arranged opposite to the first clamp 210 and clamps the other end of the battery. On the one hand, the first clamp 210 and the second clamp 220 can clamp the two ends of the battery, and on the other hand, it can be adapted to clamp batteries of different sizes or adapt to the state of the battery after expansion, and the two ends of the battery can always be coaxially arranged with the central axis of the first clamp 210 and the central axis of the second clamp 220 respectively, thereby improving the coaxiality of the battery each time it is installed, and then facilitating the control of the cutting depth to be consistent each time the cutting mechanism 700 cuts the battery shell, thereby reducing the risk of thermal runaway due to excessive cutting depth. By setting up a translation mechanism 230 so that the first clamp 210 and the second clamp 220 are moved closer to or farther away from each other, the first clamp 210 and the second clamp 220 can be moved closer to each other to clamp the battery through the translation mechanism 230, or the first clamp 210 and the second clamp 220 can be moved away from each other through the translation mechanism 230, so that the battery with thermal runaway can automatically fall from the clamping mechanism 200 into the drop port 111, and then enter the fire extinguishing box 300 for fire extinguishing.

[0102] In one embodiment of the present application, the battery disassembly device includes a control unit, the first clamp 210 and the second clamp 220 are electrically connected to the positive electrode and the negative electrode of the battery, respectively, and the first clamp 210, the second clamp 220, the control unit and the battery together form a closed electrical circuit to detect the voltage of the battery.

[0103] The control unit refers to a unit that can detect the voltage of the electrical circuit formed by the combination of the battery, the first clamp 210 and the second clamp 220. Furthermore, the control unit can also reversely control the first clamp 210 and the second clamp 220 to clamp or release the battery according to the detected voltage value.

[0104] The battery usually has a positive electrode and a negative electrode. When the first clamp 210 and the second clamp 220 are electrically connected to the positive electrode and the negative electrode of the battery respectively, the first clamp 210, the second clamp 220, the battery and the control unit can form a closed electrical circuit together, so that the current voltage of the battery can be detected by the control unit. By comparing the current voltage of the detected battery with the preset voltage value, it can be determined whether the battery is in a thermal runaway state. Specifically, when it is detected that the voltage of the battery is greater than the preset voltage value, it means that the battery is in a thermal runaway state. At this time, the control unit can control the first clamp 210 and the second clamp 220 to loosen the battery so that the battery can fall into the fire extinguishing box 300 through the drop port 111 for fire extinguishing.

[0105] With such a configuration, it is possible to determine whether the battery is in a thermal runaway state by detecting the current voltage of the battery. Thus, when it is determined that the battery is in a thermal runaway state, the first clamp 210 and the second clamp 220 can be promptly controlled to release the battery so that the battery can fall into the fire extinguishing box 300 for fire extinguishing.

[0106] Please refer to Figure 1 and Figure 2 In one embodiment of the present application, the battery disassembly device further includes a driving mechanism 500, which is disposed on a side of the clamping mechanism 200 away from the fire extinguishing box 300 and can drive the battery out of the clamping mechanism 200 in the direction of the fire extinguishing box 300.

[0107] The driving mechanism 500 refers to a mechanism for driving the battery to further effectively disengage from the clamping mechanism 200. It is understandable that when the clamping mechanism 200 includes the above-mentioned first clamp 210 and the second clamp 220, it is possible that the battery cannot be completely disengaged from the clamping mechanism 200 by only loosening the battery through the first clamp 210 or the second clamp 220, thereby causing the battery to be unable to automatically fall into the fire extinguishing box 300. Therefore, by setting up the driving mechanism 500, the battery that has detected a thermal runaway state can be driven again to disengage from the clamping mechanism 200 to enter the fire extinguishing box 300. Specifically, the driving mechanism 500 can be a cylinder, a linear motor or a connecting rod mechanism, etc. As long as pressure can be applied to the battery so that the battery can effectively disengage from the clamping mechanism 200, it will be fine.

[0108] By arranging a driving mechanism 500 on the side of the clamping mechanism 200 away from the fire extinguishing box 300, and the driving mechanism 500 can drive the battery to disengage from the clamping mechanism 200 in the direction of the fire extinguishing box 300, it can be further ensured that the battery falls smoothly into the fire extinguishing box 300, so that the battery can be extinguished in time.

[0109] Please refer to Figure 1 and Figure 2 In one embodiment of the utility model, the driving mechanism 500 includes a fixed seat 510 and a rocker arm 520, the fixed seat 510 is arranged on the base 100; the rocker arm 520 is rotatably arranged on the fixed seat 510 and is located above the clamping mechanism 200; when the rocker arm 520 rotates, it can support the battery and drive the battery to move toward the direction of the blanking port 111.

[0110] The fixing seat 510 refers to a base for connecting the rocker arm 520. It can be a column, a block or other shapes. When the fixing seat 510 is arranged on the base 100, it can be connected by screw connection, welding or other methods.

[0111] The rocker arm 520 refers to a component that can rotate and slap the battery in the direction of the drop port 111 during the rotation. The rocker arm 520 can be made of plastic or metal. In order to drive the rocker arm 520 to rotate, the rocker arm 520 can be driven to rotate manually, or the rocker arm 520 can be driven to rotate by setting an electric mechanism. For example, the electric mechanism may include a motor, and the rocker arm 520 is connected to the motor in a transmission manner. Or the electric mechanism includes a motor and a connecting rod, the motor is connected to the connecting rod in a transmission manner, and the rocker arm 520 is connected to the connecting rod in a transmission manner.

[0112] With such arrangement, the rocker arm 520 can be rotated to achieve the effect of beating the battery toward the drop port 111, thereby providing good power for the battery to effectively disengage from the clamping mechanism 200, so that the battery can enter the fire extinguishing box 300 in time for fire extinguishing.

[0113] Please refer to Figure 1 and Figure 2 Furthermore, a bayonet 521 is provided on one side of the rocker arm 520 facing the fire extinguisher box 300, and the bayonet 521 is used to hold part of the battery.

[0114] The clamping opening 521 refers to an opening for clamping a portion of the outer periphery of the battery, and the opening may be rectangular, arc-shaped or in other shapes.

[0115] By providing a bayonet 521 on the side of the rocker arm 520 facing the fire extinguisher box 300, when the rocker arm 520 rotates to support the battery, the bayonet 521 can partially support the battery, thereby increasing the area of ​​the rocker arm 520 supporting the battery and reducing the risk of damage to the battery casing by the rocker arm 520; on the other hand, it also improves the effectiveness of the rocker arm 520 in driving the battery to disengage from the clamping mechanism 200.

[0116] Furthermore, a buffer pad is provided on the inner wall of the bayonet 521 .

[0117] The buffer pad refers to a buffer component used to separate the inner wall of the bayonet 521 from the outer wall of the battery. The buffer pad can be a rubber pad, a silicone pad or a sponge pad.

[0118] Such an arrangement can reduce the risk of the rocker arm 520 hitting the battery casing and causing damage to the battery casing when the hardness of the rocker arm 520 is high.

[0119] like Figure 3 As shown, in one embodiment of the present invention, the battery disassembling device further includes a second sensor 600 , which is disposed at the cutting station and is electrically connected to the clamping mechanism 200 .

[0120] The second sensor 600 refers to a sensor for sensing whether the battery is in a thermal runaway state. The second sensor 600 may be an infrared sensor or a smoke sensor. Among them, the infrared sensor is used to determine whether the battery is in a thermal runaway state by detecting the temperature of the battery; the smoke sensor is used to determine whether the battery is in a thermal runaway state by detecting whether there is smoke around the battery. Specifically, the second sensor 600 can be arranged above the clamping mechanism 200, or can be arranged on the left, right, front, rear or bottom of the clamping mechanism 200, as long as the setting position of the second sensor 600 can detect whether the battery is in a thermal runaway state and does not affect the battery falling into the fire extinguishing chamber 310. The second sensor 600 can be arranged on the base 100. Or the second sensor 600 is arranged above the base 100. When the second sensor 600 is disposed above the base 100, in order to fix the second sensor 600, the battery disassembly device may include a shell, the shell cover is disposed outside the base 100, the clamping mechanism 200, the cutting mechanism 700, etc., and the second sensor 600 may be disposed on the shell.

[0121] By arranging the second sensor 600 at the cutting station and electrically connecting it to the clamping mechanism 200, the second sensor 600 can sense whether the battery is in a thermal runaway state. When it senses that the battery is in a thermal runaway state, the second sensor 600 transmits the signal that the battery is in a thermal runaway state to the clamping mechanism 200, and then automatically controls the clamping mechanism 200 to release the battery so that the battery can enter the fire extinguishing box 300 for fire extinguishing.

[0122] like Figure 3 As shown, based on the above-mentioned solution of providing the second sensor 600 , further, the second sensor 600 can also be electrically connected to the driving mechanism 500 .

[0123] With such arrangement, when the second sensor 600 detects that the battery is in a thermal runaway state, it controls the drive mechanism 500 to operate, so that the drive mechanism 500 drives the battery to effectively disengage from the clamping mechanism 200, so that the battery falls into the fire extinguishing box 300 in time for fire extinguishing.

[0124] In one embodiment of the utility model, the battery disassembly device also includes a dust removal component, the dust removal component includes a blowing device and an air nozzle, the blowing device includes a blowing port; the air nozzle is connected to the blowing port and faces the battery.

[0125] The blowing device refers to a device that provides a wind source. The blowing device is provided with a blowing port to facilitate blowing out the wind.

[0126] The air nozzle refers to a component used to connect the blowing device and directly blow air to the battery.

[0127] By connecting the air nozzle to the blowing port of the blowing device and pointing the air nozzle toward the battery, the blowing device can be turned on to blow air toward the battery through the air nozzle. This can, on the one hand, blow away the debris generated during the cutting of the battery shell to prevent the debris from affecting the detection effect inside the battery; on the other hand, it can also cool the cutting heat generated during the cutting of the battery shell.

[0128] Furthermore, the dust removal assembly also includes a hose, one end of the hose is connected to the air outlet, and the other end of the hose is connected to the air nozzle.

[0129] The hose can be a spring tube or other bendable tube.

[0130] By connecting one end of the hose to the air outlet and the other end to the air nozzle, the direction of the air nozzle can be changed by bending the hose, thereby changing the blowing direction, so as to more specifically blow away the debris generated during the battery cutting process.

[0131] The above are only exemplary embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields are included in the patent protection scope of the present invention.
