Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to an automatic fire extinguishing reaction and capacity-building device. Background Technology

[0002] During the formation, activation, and capacity testing of battery cells, fires may occur due to internal short circuits or other reasons. Such fires pose a significant safety threat to equipment, facilities, and personnel. Typically, battery cell formation and capacity testing equipment is equipped with fire extinguishing devices that can spray water directly at the burning cell. However, this measure not only causes significant damage to the equipment but also disrupts normal production. Utility Model Content

[0003] To address the potential fire ignition of battery cells during the formation and capacity testing stages, this invention provides an automatic fire extinguishing formation and capacity testing device. This device avoids damage to internal equipment during fire extinguishing of battery cells during the formation and capacity testing stages, while simultaneously isolating and protecting undamaged battery cells, thus improving production efficiency.

[0004] This utility model provides an automatic fire extinguishing device for forming and compatibility testing, including a battery cell tray, a dropping mechanism, a detection device, and a fire extinguishing box. The battery cell tray is used to place one or more battery cells, and the fire extinguishing box is located below the battery cell tray. The detection device is used to detect the burning battery cell during the forming and compatibility testing process, and the dropping mechanism is used to drop the burning battery cell into the fire extinguishing box for fire extinguishing.

[0005] In one embodiment, the automatic fire extinguishing compounding device further includes a main housing, which is disposed above the fire extinguishing box. The battery cell tray, the dropping mechanism, and the detection device are all disposed in the main housing. The battery cell tray is detachably connected to the dropping mechanism. The bottom of the main housing is provided with a dropping channel communicating with the fire extinguishing box.

[0006] In one embodiment, the battery cell tray is provided with a plurality of battery cell placement slots, each battery cell placement slot is used to place one battery cell, and the bottom of each battery cell placement slot is provided with an opening and closing mechanism to support the battery cell; when the detection device detects a burning battery cell, the dropping mechanism is used to open the opening and closing mechanism corresponding to the burning battery cell, so that the burning battery cell falls into the fire extinguishing box.

[0007] In one embodiment, the opening and closing mechanism is an iris-type opening and closing mechanism, which can support or release the battery cell.

[0008] In one embodiment, the dropping mechanism includes a plurality of automatic switching valves, each of which is connected to an iris-type opening and closing mechanism to control the iris-type opening and closing mechanism to support or release the battery cell.

[0009] In one embodiment, the dropping mechanism further includes a mounting frame with multiple slots on its side wall, and one automatic switching valve is positioned corresponding to one slot. Each iris-type opening and closing mechanism includes an openable and closable blade assembly and a transmission component. The blade assembly is disposed at the bottom of the battery cell placement slot to support the battery cell. One end of the transmission component is connected to the blade assembly, and the other end is correspondingly engaged in one of the slots and connected to the corresponding automatic switching valve. The automatic switching valve opens the corresponding iris-type opening and closing mechanism by pulling the transmission component.

[0010] In one embodiment, the automatic switching valve includes a pneumatic switching valve or an electric switching valve.

[0011] In one embodiment, the detection device includes a smoke alarm and a temperature probe, with each temperature probe corresponding to a battery cell. When the temperature of any of the temperature probes exceeds a threshold and the smoke alarm sounds, the battery cell corresponding to the temperature probe is the battery cell that caught fire.

[0012] In one embodiment, the fire extinguishing box includes a box body and a water tank, the water tank being disposed inside the box body and used to receive the burning battery cells thrown into the fire extinguishing box.

[0013] In one embodiment, the top of the fire extinguishing box is provided with an opening, and an isolation door is provided at the opening; when the battery cell is working normally, the isolation door is open, and when a burning battery cell is thrown into the fire extinguishing box, the isolation door is closed.

[0014] The beneficial effects of this invention are as follows: When the detection device detects a burning battery cell in the battery cell tray, the throwing mechanism throws the burning battery cell into the fire extinguishing box located below the battery cell tray for fire extinguishing. This achieves precise handling of the burning battery cell without interfering with the normal battery cell formation and capacity testing process, ensuring production continuity while protecting equipment safety. It solves the problems of direct water spraying at the formation and capacity testing location in existing technologies, which can lead to equipment damage and production disruptions, or the waste of normal battery cells due to the throwing of all cells, thus improving production economy. In addition, the fire extinguishing box is located below the battery cell tray, using gravity-assisted throwing, simplifying the throwing mechanism design, reducing energy consumption, and ensuring that the burning battery cell quickly enters the fire extinguishing area, reducing the risk of fire spread.

[0029] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0030] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0031] The terms “upper,” “lower,” “left,” “right,” “front,” “back,” “top,” “bottom,” “inner,” and “outer,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of description and simplification, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] The terms “first,” “second,” “third,” etc., are used merely to distinguish elements with similar properties, not to indicate or imply relative importance or a specific order.

[0033] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0034] like Figures 1 to 12 As shown, this utility model provides an automatic fire extinguishing reaction and capacity-setting device, including a battery cell tray 1, a throwing mechanism 2, a detection device 3, and a fire extinguishing box 5. The battery cell tray 1 is used to place one or more battery cells 8. The fire extinguishing box 5 is located below the battery cell tray 1. The detection device 3 is used to detect the burning battery cell 8 during the battery cell reaction and capacity-setting process. The throwing mechanism 2 is used to throw the burning battery cell 8 into the fire extinguishing box 5 for fire extinguishing.

[0035] In this embodiment, when the detection device 3 detects a burning battery cell 8 in the battery cell tray 1, the throwing mechanism 2 throws the burning battery cell 8 into the fire extinguishing box 5 located below the battery cell tray 1 for fire extinguishing. This achieves precise handling of the burning battery cell 8 without interfering with the normal battery cell 8 formation and capacity testing process, ensuring production continuity while protecting equipment safety. This solves the problems of direct water spraying at the formation and capacity testing location in the prior art, which leads to equipment damage and production disruption, or the waste of normal battery cells due to the throwing of all battery cells 8, thus improving production economy. In addition, the fire extinguishing box 5 is located below the battery cell tray 1, using gravity-assisted throwing, which simplifies the design of the throwing mechanism 2, reduces energy consumption, and ensures that the burning battery cell 8 quickly enters the fire extinguishing area (i.e., the area inside the fire extinguishing box 5), reducing the risk of fire spread.

[0036] As one implementation method, such as Figure 1 and Figures 6 to 10 As shown, the automatic fire extinguishing device also includes a main housing 4, which is located above the fire extinguishing box 5. The battery cell tray 1, the throwing mechanism 2, and the detection device 3 are all located inside the main housing 4, forming a separation area from the fire extinguishing area. The main housing 4 achieves "component integration assembly," preventing components from being exposed to dust and electrolyte contamination. Simultaneously, the partitioned design with the fire extinguishing box 5 reduces interference between components and improves the overall stability of the device. The battery cell tray 1 is detachably connected to the throwing mechanism 2 (as described below, the throwing mechanism 2 is connected to the battery cell tray 1 via an opening and closing mechanism 7), facilitating the separation of the battery cell tray 1 from the throwing mechanism 2 and its removal from the main housing 4 for the removal or placement of the battery cells 8. The bottom of the main housing 4 has a throwing channel 41 communicating with the fire extinguishing box 5, allowing the thrown battery cells 8 to fall into the fire extinguishing box 5 through the throwing channel 41.

[0037] As one implementation method, such as Figure 1 and Figures 8 to 10As shown, the automatic fire extinguishing formation and capacity testing device also includes a needle plate 6, which is positioned above the cell tray 1. At the bottom of the needle plate 6, corresponding to each cell placement position, a probe assembly 61 is provided. The probe assembly 61 is used to contact the tabs of the cell 8 at each placement position to establish or disconnect the electrical path. Each probe assembly 61 includes at least four positive probes 611 and one negative probe 612, respectively used to precisely contact the positive and negative tabs of a single cell 8, establishing an independent electrical path for that cell 8 (the path can be individually controlled for on / off), enabling independent formation and capacity testing of a single cell 8. The probe assemblies 61 corresponding to different cells 8 do not interfere with each other, ensuring that the charging / discharging control and data acquisition of each cell 8 are performed independently, without affecting the testing process of other cells 8.

[0038] As one implementation method, such as Figures 1 to 5 As shown, the cell tray 1 has multiple cell placement slots 11. These slots 11 provide circumferential constraints on the cells 8, preventing displacement during capacity testing that could prevent the establishment of an electrical path and thus detection failure. The multiple independent slots 11 ensure that each cell is independently supported, preventing mutual interference in the event of a fire. Each slot 11 has an opening / closing mechanism 7 at its bottom to support the cell 8 (i.e., the slot 11 is a through-hole). When the detection device 3 detects a burning cell 8, the dropping mechanism 2 opens the opening / closing mechanism 7 corresponding to the burning cell 8, allowing it to fall into the fire extinguishing box 5. In this embodiment, by independently placing each cell 8 in a single slot 11, the falling of a burning cell 8 avoids affecting the normal cells, while the through-hole ensures the cell 8 falls smoothly into the fire extinguishing box 5. The cell placement slot 11 is cylindrical, suitable for capacity testing of cylindrical batteries. The cell placement slot 11 can also be configured in other shapes to form and quantify cells with other shapes.

[0039] In one implementation, the opening and closing mechanism 7 is an iris-type opening and closing mechanism, which can support or release the battery cell 8.

[0040] As one implementation method, such as Figure 6 As shown, the dropping mechanism 2 includes multiple automatic switching valves 22, and each automatic switching valve 22 is connected to an iris-type opening and closing mechanism to control the iris-type opening and closing mechanism to support or release the battery cell 8.

[0041] As one implementation method, such as Figures 2 to 7As shown, the dropping mechanism 2 also includes a mounting frame 21. The side wall of the mounting frame 21 is provided with multiple slots 211. One automatic switching valve 22 is set at the position of one slot 211. Each iris-type opening and closing mechanism includes a transmission component 72 and an openable and closable blade assembly 71. The blade assembly 71 is set at the bottom of the battery cell placement slot 11 to support the battery cell 8. One end of the transmission component 72 is connected to the blade assembly 71, and the other end is correspondingly engaged in a slot 211 and connected to the corresponding automatic switching valve 22. The automatic switching valve 22 opens the corresponding iris-type opening and closing mechanism by pulling the transmission component 72.

[0042] Specifically, the blade assembly 71 includes an annular frame 711, a turntable 713, a cover plate 714, and multiple blades 712. Both the annular frame 711 and the turntable 713 have a centrally hollowed-out section to facilitate the passage of the ignited battery cell 8. The outer edge of the annular frame 711 protrudes to form a mounting groove 715, and the multiple blades 712 are arranged symmetrically around the center of the annular frame 711 within the mounting groove 715. The turntable 713 is located on the side of the blades 712 away from the annular frame 711, and the annular cover plate 714 is located on the side of the turntable 713 away from the blades 712. The cover plate 714 is fixedly connected to the outer edge of the annular frame 711 (e.g., by bolts), and the turntable 713 can rotate between the annular frame 711 and the cover plate 714. The outer periphery of the annular frame 711 is fixedly connected to the inner wall of the battery cell placement groove 11. Each blade 712 has a first slider 712A (which can be cylindrical) and a second slider 712B (which can be cuboid) on the side facing the annular frame 711 and the side facing the turntable 713, respectively. The annular frame 711 has a plurality of first grooves 711A arranged in a ring and symmetrically distributed around the center of the annular frame 711. The turntable 713 also has a plurality of second grooves 713A arranged in a ring and symmetrically distributed around the center of the annular frame 711. The first sliders 712A on the blade 712 are embedded one-to-one into the first grooves 711A of the annular frame 711, and the second sliders 712B on the blade 712 are embedded one-to-one into the second grooves 713A of the turntable 713, so as to limit the rotation trajectory of the blade 712. The turntable 713 has an outwardly extending connecting rod 716 on its outer periphery. The side wall of the mounting groove 715 has a clearance groove 718 corresponding to the position of the connecting rod 716. The end of the connecting rod 716 can pass through the clearance groove 718 and connect to one end of the transmission component 72. The annular frame 711 has an outwardly extending positioning rod 717 on its outer periphery. The other end of the transmission component 72 passes through the through hole on the positioning rod 717 and is used to connect to the automatic switching valve 22.

[0043] The transmission component 72 includes a wire rope 721, a wire rope clamp 722, and a spring 723. One end of the wire rope 721 is connected to the connecting rod 716 of the turntable 713 via a fixed end 724, and the other end passes through a through hole (not shown) on the positioning rod 717 of the annular frame 711 and connects to the wire rope clamp 722. The wire rope clamp 722 passes through the side wall of the battery cell tray 1. The side wall of the mounting bracket 21 has a docking groove 213, and each clamp 211 is located within the docking groove 213. When the battery cell tray 1 is assembled in place, the wire rope clamps 722 are correspondingly clamped into the clamping grooves 211, and the wire rope clamps 722 are connected to the output end of the automatic switching valve 22 at the corresponding position.

[0044] Furthermore, spring 723 is fitted onto steel wire rope 721. When automatic switch valve 22 drives steel wire rope 721, steel wire rope 721 pulls connecting rod 716 to rotate turntable 713. During the rotation of turntable 713, multiple blades 712 rotate, causing the blades 712 of the iris-type opening and closing mechanism to open. When the burning battery cell 8 falls, spring 723 is compressed, with one end abutting against the fixed end 724 of steel wire rope 721 and the other end abutting against positioning rod 717. After the action of throwing the battery cell 8 is completed, automatic switch valve 22 stops driving. At this time, spring 723 releases elastic potential energy, pushing steel wire rope 721 to reset, thereby causing multiple blades 712 to close again. This ensures that the iris-type opening and closing mechanism can return to its initial state, preparing for the placement of the potentially thrown battery cell 8, and ensuring the continuity and stability of the operation of the iris-type opening and closing mechanism.

[0045] When the cell tray 1 is assembled, the mounting frame 21 partially surrounds the outer periphery of the cell tray 1. Multiple wire rope clips 722 are arranged on opposite sides of the cell tray 1. The mounting frame 21 includes two opposing side plates 212, located on either side of the cell tray 1 through which the wire rope clips 722 pass. Both side plates 212 have mating grooves 213, and each mating groove 213 has a corresponding slot 211 for each wire rope clip 722. An automatic switching valve 22 is located at the position of each slot 211. One wire rope clip 722 engages with one slot 211 to connect with the corresponding automatic switching valve 22.

[0046] During operation: When the detection device 3 detects that a certain battery cell 8 is on fire, the dropping mechanism 2 triggers the opening and closing mechanism 7 of the corresponding placement slot. That is, after the automatic switch valve 22 is triggered, it outputs driving force, pulling the wire rope clamp 722 to drive the connecting rod 716 of the turntable 713 connected to it. The turntable 713 drives the blades 712 to slide along the direction of the slide grooves (first slide groove 711A and second slide groove 713A). The closed parts between multiple blades 712 separate (clutch action), and finally open the bottom channel of the battery cell placement slot 11. The burning battery cell 8 falls into the fire extinguishing box 5. The opening and closing mechanisms 7 of other battery cell placement slots 11 remain closed, without affecting the normal battery cells 8. After the action of dropping the battery cell 8 is completed, the automatic switch valve 22 stops driving. At this time, the spring 723 releases elastic potential energy, pushes the wire rope 721 to reset, and then drives multiple blades 712 to close again.

[0047] In one implementation, the automatic switching valve 22 includes a pneumatic switching valve and an electric switching valve.

[0048] As one implementation method, such as Figure 1 , Figures 8 to 10 As shown, the detection device 3 includes a smoke alarm 31 and multiple temperature probes 32. Each temperature probe 32 corresponds to a battery cell 8, with one probe 32 positioned above a battery cell placement slot 11. When the temperature detected by any temperature probe 32 exceeds a threshold and the smoke alarm 31 sounds, the battery cell 8 corresponding to that probe 32 is identified as the one on fire. The dropping mechanism 2 then drops the burning battery cell 8 corresponding to that probe 32 into the fire extinguishing box 5. Specifically, multiple temperature probes 32 are positioned at the bottom of the needle plate 6, corresponding to the positions of multiple battery cell placement slots 11. Through the dual detection of "precise positioning by the temperature probe 32 + secondary confirmation by the smoke alarm 31," false judgments from a single sensor are avoided, achieving accurate identification of the burning battery cell 8.

[0049] As one implementation method, the temperature rise of different models of battery cells 8 during formation and capacity testing is different. Therefore, the threshold T set by the temperature probe 32 is also different. The range of the threshold T is: 68℃≤T≤200℃. The alarm threshold of the smoke alarm 31 complies with the provisions of the national standard GB20517-2006 "Standalone Smoke Detector".

[0050] As one implementation method, such as Figure 1 and Figure 11 As shown, the fire extinguishing box 5 includes a box body 51 and a water tank 52. The water tank 52 is disposed inside the box body 51 and is used to receive the burning battery cells 8 that fall into the fire extinguishing box 5. A water spray assembly (not shown) may be installed inside the box body 51. The water spray assembly is connected to a water injection valve 57 located outside the box body 51. The water injection valve 57 is further connected to a water source, allowing for fire extinguishing via water spraying from the water spray assembly.

[0051] As one implementation method, such as Figure 11 and Figure 12 As shown, the top of the fire extinguishing box 5 is provided with an opening 53, that is, the top of the box body 51 is provided with an opening 53, and an isolation door 54 is provided at the opening 53. When the battery cell 8 is working normally, the isolation door 54 is open. When a burning battery cell 8 is thrown into the fire extinguishing box 5, the isolation door 54 is closed. Specifically, the inner top surface 511 of the box body 51 is provided with a sliding connection structure 55 connected to the isolation door 54. The sliding connection structure 55 includes a slide rail 551 and a slider 552. The inner top surface 511 of the box body 51 is fixed with a slide rail 551 extending along the length direction L. The two isolation doors 54 are arranged opposite to each other along the length direction L of the box body 51. The outer side of each of them is fixed with a slider 552 adapted to the slide rail 551, so that the two isolation doors 54 can move away from each other along the length direction L (opening the opening 53) or move closer to each other (closing the opening 53). The inner top surface 511 of the housing 51 is also equipped with two drive mechanisms 56 (such as electric push rods). Each drive mechanism 56 is connected to an isolation door 54 and is used to drive the corresponding isolation door 54 to slide along the slide rail 551, thereby realizing the automatic opening or closing of the opening 53. Of course, a single-door design can also be adopted: only one isolation door 54 is set, which slides along the slide rail 551 on one side of the inner top surface 511 of the housing 51. The opening and closing of the opening 53 is achieved by "sliding to one side to open and sliding towards the center of the opening 53 to close". The battery cell placement slot 11 of the battery cell tray 1, the drop channel 41 at the bottom of the main housing 4, and the opening 53 at the top of the fire extinguishing box 5 form the drop path of the burning battery cell 8.

[0052] As one implementation method, a control system is also included. The control system is connected to the throwing mechanism 2, the detection device 3, and the fire extinguishing box 5. The control system receives the fire signal (temperature exceeding the threshold + smoke alarm) from the detection device 3; analyzes the number of the corresponding battery cell 8; sends a command to the automatic switching valve 22 of the corresponding throwing mechanism 2 to trigger the opening and closing mechanism 7; after throwing the burning battery cell 8 to the fire extinguishing box 5, it sends a command to the fire extinguishing box 5 to open the water spray assembly and close the isolation door 54; after the fire is extinguished, it sends a command to close the water spray assembly and open and reset the isolation door 54; thus realizing a fully automatic closed-loop control of "detection-throwing-fire extinguishing" without manual intervention, avoiding delays caused by manual operation that could lead to the spread of the fire.

[0053] The automatic fire extinguishing device of this utility model mainly includes a battery tray 1, a throwing mechanism 2, a detection device 3 (temperature probe 32 and smoke alarm 31), and a fire extinguishing box 5 with isolation and water spraying functions, as detailed below: ① The battery cell tray 1 includes multiple battery cell placement slots 11. Each battery cell placement slot 11 has an opening and closing mechanism 7 (such as an iris-type opening and closing mechanism). The opening and closing mechanism 7 is opened by pulling a steel wire rope 721 and automatically closed by a spring 723. The edge of the battery cell tray 1 is provided with a steel wire rope clip 722 for docking. ② The linked dropping mechanism 2 is provided with a slot 211 that can be connected to the wire rope clamp 722. The wire rope clamp 722 is connected to the automatic switch valve 22 (such as an actuator cylinder) in the slot 211. After the battery cell tray 1 is placed in place, the wire rope clamp 722 and the automatic switch valve 22 form a linkage mechanism. The actuator cylinder can open the iris-type opening and closing mechanism to realize the dropping of the battery cell 8. ③ Temperature probe 32 and smoke alarm 31: Multiple temperature probes 32 are installed on the needle plate 6 inside the main box 4, which can monitor the temperature of each battery cell 8 in real time. At the same time, a smoke alarm 31 is installed above the needle plate 6. When the battery cell 8 catches fire, it will produce a lot of smoke and high temperature flames. The control system can determine the existence of fire and the location of the burning battery cell 8 by comprehensively judging the information of the temperature probe 32 and the smoke alarm 31. ④ The fire extinguishing box 5, which can isolate water spray, is designed with an isolation door 54, a water spray assembly, and a water tank 52 below the battery cell tray 1. When the battery cell 8 catches fire, the control system alarms and issues an action command. The iris-type opening and closing mechanism opens, and the single burning battery cell is immediately thrown into the water tank 52. Then, the isolation door 54 closes, and the water spray assembly starts spraying water into the water tank 52, thus isolating and extinguishing the fire of the battery cell 8. Of course, the fire extinguishing box 5 can also be without a water spray assembly, and a certain amount of water can be pre-filled in the water tank 52. When the battery cell 8 catches fire, it is thrown into the water tank 52 for fire extinguishing.

[0054] After the battery cell tray 1 enters the main housing 4, it will engage with the linkage throwing mechanism 2. The throwing mechanism 2 can control the opening and closing of the iris-type opening and closing mechanism at each battery cell 8 position. When a battery cell 8 at a certain position catches fire, the temperature probe 32 will detect the overheating of the corresponding battery cell 8, and at the same time, the smoke alarm 31 will detect smoke. The control system will comprehensively determine that the battery cell 8 is on fire and immediately control the linkage throwing mechanism 2 to open the iris-type opening and closing mechanism at the corresponding battery cell 8 position, so that the battery cell 8 slides into the fire extinguishing box 5 at the bottom, which can isolate water spray. Then the isolation door 54 is closed (the water injection valve 57 can be opened at the same time to inject water, or water can be injected into the water tank 52 beforehand) to extinguish the fire of the battery cell 8 in the water tank 52 and protect the safety of the factory, equipment and personnel.

[0055] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
