Description

Technical Field

[0001] This utility model relates to a battery leakage detection device. Background Technology

[0002] In existing technologies, to improve testing efficiency, multiple batteries are typically tested simultaneously during battery testing. Testing equipment usually consists of a hopper with multiple shelves arranged vertically, each shelf capable of holding batteries to be tested. During loading and unloading, the upper shelves can obstruct the lower shelves. Common solutions to this include: 1. Removing the shelves during loading and unloading, then reinstalling them afterward. This method is complex and increases the difficulty of loading and unloading; 2. Increasing the size of the shelves to ensure the unobstructed portion can hold a predetermined number of batteries, while the obstructed portion remains unoccupied. This method increases the hopper's volume, occupies more space, and may also affect testing efficiency. Utility Model Content

[0007] In some embodiments, a top plate is provided between the upper portions of the two fixing plates, the top plate being located above the accommodating space, and the distance between the lower surface of the top plate and the upper surface of the product to be tested on the support frame located below is 0.3 mm to 0.7 mm.

[0008] In some embodiments, the loading platform includes a side plate connected between the two fixed plates, the side plate and the two fixed plates surrounding the periphery of the accommodating space; the support frame is provided with a connector on the side facing the side plate, and when the support frame is in the first state, the support frame retracts relative to the side plate along the second direction, and the connector abuts against the side plate.

[0009] In some embodiments, a magnetic attraction structure is provided between the connector and the side plate. In some embodiments, either the connector or the side plate is provided with a buffer structure.

[0010] In some embodiments, the support frame is provided with a detection element on one side along the second direction, and the detection device is provided with a positioning sensing module; when the support frame is in the first state, the detection element is within the sensing range of the positioning sensing module and triggers the positioning sensing module.

[0011] In some embodiments, the positioning sensing module includes a transmitter for emitting a detection beam, the transmitter being disposed on one side of the fixed plate along the second direction, the transmitter including a plurality of transmitters spaced apart along the vertical direction, the detection beam emitted by the transmitter extending parallel to the first direction; when the support frame is in the first state, the detection element is located on the transmission path of the detection beam.

[0012] In some embodiments, the detection device is provided with a transmission guide rail extending along the first direction, the material platform is movably disposed on the transmission guide rail, the transmitter is disposed on one side of the transmission guide rail along the second direction, and the detection beam emitted by the transmitter extends parallel to the transmission guide rail.

[0013] In some embodiments, the fixing plate is provided with a through hole extending in a second direction, the through hole being located between two adjacent support frames in a vertical direction.

[0014] In some embodiments, one of the fixed plate and the sliding member is provided with a first limiting groove extending along the second direction, and the other of the two is provided with a first limiting member, which is movably inserted into the first limiting groove.

[0019] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: In the battery leakage detection device of this utility model, a sliding member is provided between the fixed plate and the support frame on the loading platform. The sliding member is slidably connected to the fixed plate and also slidably connected to the support frame. During loading and unloading, the sliding member can be driven to slide a first distance relative to the fixed plate, and the support frame can be driven to slide a second distance relative to the sliding member. Thus, the total distance the support frame slides relative to the fixed plate is the sum of the first and second distances. The support frame can slide a greater distance, allowing it to fully extend out of the accommodating space and thus be unaffected by the upper support frame. The sliding member does not occupy a large volume, thus not significantly affecting the space occupied by the loading platform, but effectively solves the problem of obstruction during loading and unloading.

[0021] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments, so that the advantages and features of this utility model can be more easily understood by those skilled in the art. Obviously, the embodiments described in this application are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this application without creative effort are within the scope of protection of this application.

[0022] See Figure 1 , Figure 2 A battery leakage detection device is shown, comprising a detection apparatus for performing detection operations. The detection apparatus includes a loading platform 1 and a top cover 21. The loading platform 1 includes a base 11, a fixing plate 12, a support frame 13, and a sliding member 14. Two fixing plates 12 are spaced apart on the upper part of the base 11 along a first direction, forming an accommodating space between the base 11 and the two fixing plates 12. The support frame 13 is located between the two fixing plates 12 along the first direction and has accommodating slots 130 for placing products to be tested. In this embodiment, multiple support frames 13 are spaced apart along the vertical direction, which can increase the number of products to be tested that the loading platform 1 can hold, thereby increasing the number of products participating in each test and improving detection efficiency. Preferably, each support frame 13 is provided with multiple accommodating slots 130, so that multiple products to be tested can be placed on top of each support frame 13, further increasing the number of products participating in the test and improving efficiency.

[0023] In this embodiment, see Figures 4 to 6 As shown, the sliding member 14 is disposed between the support frame 13 and the fixed plate 12. The sliding member 14 extends along a second direction, which is perpendicular to the first direction. The sliding member 14 is slidably connected to the fixed plate 12 along the second direction, and also slidably connected to the support frame 13 along the second direction. By providing the sliding member 14, the displacement of the support frame 13 relative to the fixed plate 12 can be effectively increased without excessively increasing the volume of the loading platform 1. Specifically, the support frame 13 has a first state and a second state. In the first state, the support frame 13 and the sliding member 14 are folded relative to the fixed plate 12 along the second direction, and the support frame 13 is housed within the accommodating space. In the second state, see [reference needed]. Figure 7 , Figure 8 As shown, the sliding member 14 unfolds relative to the fixed plate 12 along the second direction, and the support frame 13 unfolds relative to the sliding member 14 along the second direction, so that the support frame 13 extends out of the accommodating space.

[0024] In this embodiment, when the loading platform 1 transitions from the first state to the second state, the sliding member 14 slides a first distance relative to the fixed plate 12 along the second direction, and then the support frame 13 slides a second distance relative to the fixed plate 12. The total distance the support frame 13 can move relative to the fixed plate 12 is the sum of the first and second distances. Compared to the support frame 13 being directly slidably connected to the fixed plate 12, the support frame 13 can slide a greater distance. In some preferred embodiments, by setting the first and second distances, the support frame 13 can extend more completely out of the accommodating space in the second state, thereby avoiding obstruction of the support frame 13 in the vertical direction and facilitating the loading and unloading of the product to be tested. In this embodiment, in the first state, the support frame 13 is folded within the accommodating space, and the sliding member 14 is folded between the support frame 13 and the fixed plate 12. The sliding member 14 has a small size in the first direction and will not significantly affect the size of the loading platform 1. Thus, the problem of mutual obstruction during loading and unloading is solved while effectively controlling the volume of the loading platform 1.

[0025] In this embodiment, the upper cover 21 is vertically adjustable. When the testing device is in the testing state, the support frame 13 is in the first state, the upper cover 21 is placed on the material platform 1, and the upper cover 21 and the base 11 are sealed together, forming a sealed cavity. The support frame 13 is located in the sealed cavity. In this embodiment, the testing device also includes a vacuum module (not shown in the figure) for drawing a vacuum into the sealed cavity. After the upper cover 21 is placed on the material platform 1 and a sealed cavity is formed, the vacuum module draws a vacuum to a set value, creating a negative pressure environment inside the sealed cavity. Under this negative pressure environment, if there is product leakage, the leaked electrolyte will diffuse into the sealed cavity. In this embodiment, the testing device is also equipped with a testing instrument, which is connected to the sealed cavity. The testing instrument can detect the environment inside the sealed cavity and determine whether leakage has occurred.

[0026] In this embodiment, see Figure 7 As shown, each carrier 13 is provided with four receiving slots 130. When the carrier 13 is in the second state, the four receiving slots 130 can fully extend out of the receiving space and are not blocked by the carrier 13 above, so that the product to be tested can be placed smoothly in the receiving slots 130.

[0027] In this embodiment, a traction member 16 is fixedly provided on one side of the support frame 13 along the second direction. The detection device includes a pulling mechanism 3, which is configured to drive the support frame 13 to move along the second direction by pulling the traction member 16, thereby causing the support frame 13 to extend out of the accommodating space or to retract into the accommodating space. Specifically, the traction member 16 is provided with a slot 161, and the pulling mechanism 3 is provided with a connector 31 that can be inserted into the slot 161. The connector 31 is configured to move both along the second direction and up and down.

[0028] In this embodiment, slot 161 extends along the first direction, see [reference]. Figure 12 As shown, the material pulling mechanism 3 includes a movable frame 32 that can move along a second direction, a lifting frame 33 that can be movably mounted on the movable frame 32, and a telescopic frame 34 that can move along a first direction and is mounted on the lifting frame 33. A connector 31 is mounted on the telescopic frame 34. Specifically, the testing equipment is provided with a slide rail 35 extending along the second direction, and the movable frame 32 is slidably connected to the slide rail 35. When loading material into the loading platform 1, the material pulling mechanism 3 drives the movable frame 32 and the lifting frame 33 to move, aligning the connector 31 with the slot 161 along the first direction. Then, it drives the telescopic frame 34 to insert the connector 31 into the slot 161. Afterward, it drives the movable frame 32 to move along the second direction, causing the carrier frame 13 to extend out of the receiving space along the second direction. After placing the product in the receiving slot 130 on the carrier frame 13, the movable frame 32 drives the carrier frame 13 to move into the receiving space. By adjusting the height of the telescopic frame 34 and repeating the above operation, the loading of all the support frames 13 can be completed in a coordinated manner without the need for manual intervention, thus realizing automated loading operation.

[0029] In this embodiment, the loading platform 1 includes a side plate 15 connected between two fixed plates 12. The side plate 15 and the two fixed plates 12 surround the periphery of the accommodating space. The accommodating space forms an inlet and outlet for the support frame 13 to enter and exit the accommodating space on the side opposite to the side plate 15 along the second direction. When the support frame 13 is in the first state, the support frame 13 moves closer to the side plate 15 along the second direction. When the support frame 13 changes from the first state to the second state, the support frame 13 moves away from the side plate 15 along the second direction and extends out of the accommodating space from the inlet and outlet.

[0030] In this embodiment, a magnetic attraction structure is provided between the side portion of the support frame 13 facing the side plate 15 and the side plate 15. Specifically, a connector 17 is provided on the side portion of the support frame 13 facing the side plate 15. When the support frame 13 is in the first state, the connector 17 abuts against the side plate 15. A magnetic attraction structure is provided between the connector 17 and the side plate 15. When transitioning from the second state to the first state, the magnetic attraction can be used to fix the connector 17 and the side plate 15, thereby fixing the support frame 13 and the side plate 15, so that the loading platform 1 can be stably maintained in the first state.

[0031] Preferably, a buffer structure is provided on either the side of the support frame 13 facing the side plate 15 or on the side plate 15. During the process of the pulling mechanism 3 driving the support frame 13 towards the side plate 15, the buffer structure can function to prevent a hard collision between the support frame 13 and the side plate 15. In this embodiment, the buffer structure is provided on the side plate 15.

[0032] In this embodiment, see Figure 4As shown, a top plate 19 is provided above the fixed plate 12. The top plate 19 is fixed between the upper parts of the two fixed plates 12. The top plate 19 is located above the accommodating space. A box-shaped structure is formed between the top plate 19, the side plate 15 and the two fixed plates 12.

[0033] In this embodiment, the distance between the lower surface of the upper support frame 13 and the upper surface of the product to be tested located on the lower support frame 13 is 0.3mm to 0.7mm. In this embodiment, the product to be tested is a battery. The above arrangement provides a gap for vacuum extraction, and the above distance also prevents the battery from bulging during vacuum extraction.

[0034] In this embodiment, the distance between the lower surface of the top plate 19 and the upper surface of the product to be tested on the support frame 13 located below is 0.3mm to 0.7mm. With this distance, it is possible to ensure that a vacuum can be drawn while avoiding the bulging of the uppermost battery.

[0035] In this embodiment, a detection element 18 is provided on one side of the support frame 13 along the second direction. The detection equipment is equipped with a positioning sensing module. When the support frame 13 is in the first state, the detection element 18 is within the sensing range of the positioning sensing module and triggers the positioning sensing module. The positioning sensing module cooperates with the detection element 18 to detect whether the support frame 13 is housed within the accommodating space, thereby ensuring that subsequent vacuuming and detection operations can proceed normally.

[0036] In this embodiment, see Figure 6 , Figure 8 As shown, the side plate 15 has a hollow design and multiple perforations 151 to facilitate subsequent vacuuming. In this embodiment, the position sensing module is disposed on the side of the side plate 15 away from the accommodating space along the second direction. When the support frame 13 is housed in the accommodating space, the detection element 18 extends out of the accommodating space from the perforations 151 on the side plate 15 and extends to the other side of the side plate 15, thereby entering the sensing range of the position sensing module.

[0037] In this embodiment, the support frame 13 has two connectors 17 on its side, and the two connectors 17 are arranged on both sides of the detection member 18 along the first direction. Specifically, see Figure 6 , Figure 7 As shown, the two connectors 17 and the detection component 18 are integrated and arranged in a mountain shape.

[0038] In this embodiment, the positioning sensing module includes a transmitter 41 for emitting a detection beam 411. The transmitter 41 is disposed on one side of the fixing plate 12 along a second direction. Specifically, the transmitter 41 is disposed on the side of the side plate 15 opposite to the accommodating space along the second direction. See also Figure 3As shown, the transmitter 41 includes a plurality of transmitters spaced apart along the vertical direction. The detection beams 411 emitted by the transmitter 41 are parallel to each other and extend parallel to the first direction. When the support frame 13 is in the first state, the detection element 18 is located on the transmission path of the detection beam 411.

[0039] In some embodiments, the position sensing module further includes a receiver for receiving the detection beam 411. The position sensing module can determine whether the carrier 13 is in the first state and whether the carrier 13 is correctly housed in the accommodating space based on whether the receiver receives the detection beam 411.

[0040] In this embodiment, the detection device is provided with a transmission guide rail 51 extending along a first direction. The material platform 1 is movably disposed on the transmission guide rail 51, and the transmitter 41 is disposed on one side of the transmission guide rail 51 along a second direction. The detection beam 411 emitted by the transmitter 41 extends parallel to the transmission guide rail 51. In some embodiments, the detection beam 411 extends along the transmission guide rail 51, so that the position sensing module can monitor the position of the support frame 13 throughout the entire process of the material platform 1 being transported along the transmission guide rail 51, thereby ensuring the normal operation of the entire detection process.

[0041] In this embodiment, the testing equipment includes a transmission component 52 capable of transporting along the transmission guide rail 51. A loading platform 1 is fixed to the transmission component 52; specifically, the transmission component 52 is equipped with a fixing assembly for securing the loading platform 1. Along the transmission direction of the transmission component 52, a loading station 511, a testing station 512, and a unloading station 513 are sequentially arranged. At the loading station 511, the product to be tested is placed on the loading platform 1, and at the unloading station 513, the product is removed from the loading platform 1. The upper cover 21 is located above the testing station 512, where leakage detection is performed. See also... Figure 3 As shown, the loading station 511 and unloading station 513 are located at opposite ends of the transmission guide rail 51, while the detection station 512 is located in the middle of the transmission guide rail 51. In these embodiments, both the loading station 511 and the unloading station 513 are equipped with a position sensing module. In some embodiments, the material carrier 1 is within the detection range of the position sensing module along the transmission path of the transmission guide rail 51.

[0042] In this embodiment, the fixing plate 12 is provided with a through hole 122 to facilitate vacuum extraction. Specifically, the fixing plate 12 is provided with a through hole 122 extending in the second direction. The through hole 122 is located between two adjacent support frames 13 in the vertical direction. On the one hand, it is convenient to extract vacuum, and on the other hand, when there is a leakage problem, it is convenient for the leaked electrolyte to diffuse into the sealed cavity.

[0043] In this embodiment, one of the sliding member 14 and the fixed plate 12 is provided with a first sliding groove 121, and the other is provided with a first connecting part 141. The first connecting part 141 is movably inserted into the first sliding groove 121, thereby realizing the sliding connection between the sliding member 14 and the fixed plate 12. In this embodiment, the outer surface of the first connecting part 141 is in surface contact with the groove wall of the first sliding groove 121 and can slide relative to each other. The surface-to-surface contact and surface-to-surface sliding method can reduce the cavity that can retain air, thereby facilitating the vacuum module to draw a vacuum and ensuring that the preset negative pressure environment can be achieved.

[0044] In this embodiment, one of the sliding member 14 and the support frame 13 is provided with a second sliding groove 131, and the other is provided with a second connecting part 142. The second connecting part 142 is movably inserted into the second sliding groove 131, thereby realizing a sliding connection between the sliding member 14 and the support frame 13. In this embodiment, the outer surface of the second connecting part 142 is in surface contact with the groove wall of the second sliding groove 131 and can slide relative to each other. The sliding member 14 and the support frame 13 are also connected by surface-to-surface contact and surface-to-surface sliding, which facilitates vacuuming.

[0045] In this embodiment, see Figure 5 As shown, the fixed plate 12 is provided with a first sliding groove 121, and the sliding member 14 has a first connecting part 141; the support frame 13 is provided with a second sliding groove 131, and the sliding member 14 has a second connecting part 142.

[0046] In this embodiment, see Figure 5 As shown, the cross-section of the first connecting portion 141 is trapezoidal, and the first sliding groove 121 is a dovetail groove. In this embodiment, the cross-section of the second connecting portion 142 is trapezoidal, and the second sliding groove 131 is a dovetail groove. In other embodiments, the cross-sections of the first connecting portion 141 and the second connecting portion 142 can adopt other shapes, the first sliding groove 121 adopts a shape that matches the cross-section of the first connecting portion 141, and the second sliding groove 131 adopts a shape that matches the cross-section of the second connecting portion 142, to avoid the formation of cavities between the first connecting portion 141 and the first sliding groove 121, and between the second connecting portion 142 and the second sliding groove 131.

[0047] In this embodiment, one of the fixed plate 12 and the sliding member 14 is provided with a first limiting groove 123 extending along the second direction, and the other of the two is provided with a first limiting member 143, which is movably inserted into the first limiting groove 123. The sliding distance of the sliding member 14 relative to the fixed plate 12 is limited by the cooperation between the first limiting member 143 and the first limiting groove 123.

[0048] In this embodiment, one of the support frame 13 and the slider 14 is provided with a second limiting groove 132 extending along the second direction, and the other of the two is provided with a second limiting member (not shown in the figure). The second limiting member is movably inserted into the second limiting groove 132. The sliding distance of the support frame 13 relative to the slider 14 is limited by the cooperation between the second limiting member and the second limiting groove 132.

[0049] In this embodiment, a sealing ring 111 is provided on the base 11. When the upper cover 21 is placed on the material carrier 1, the bottom of the upper cover 21 engages with the sealing ring 111 to form a seal, thereby forming a sealed cavity. See also: Figure 9 As shown, the detection device also includes a lifting mechanism 22 for driving the upper cover 21 to move up and down.

[0050] In this embodiment, see Figure 10 and Figure 11 As shown, the testing equipment also includes a feeding mechanism 6 for providing the product to be tested, i.e., a battery, and a loading mechanism 71 for transferring the product to be tested from the feeding mechanism 6 to the loading platform 1. See also Figure 11 As shown, the feeding mechanism 71 includes a movable conveying head 711. In this embodiment, the conveying head 711 has a suction nozzle, which adsorbs and fixes the product.

[0051] In this embodiment, both the loading station 511 and the unloading station 513 are equipped with a pulling mechanism 3. The pulling mechanism 3 at the loading station 511 is used to cooperate with the loading mechanism 71 to transport the product onto the loading platform 1. The unloading station 513 is also equipped with an unloading mechanism 72 for removing the product from the loading platform 1. The pulling mechanism 3 at the unloading station 513 cooperates with the unloading mechanism 72. In this embodiment, see... Figure 13 As shown, the feeding mechanism 72 also includes a movable handling head 711.

[0052] In this embodiment, the detection equipment is equipped with two sets of detection devices, see [link to documentation]. Figure 1 , Figure 2 As shown, two sets of detection devices are arranged side by side along the second direction, and the detection equipment is equipped with two parallel transmission guide rails 51. In this embodiment, the vacuum module is connected to the two detection devices through pipelines. A control valve for controlling the opening and closing of the pipeline is provided on the pipeline connecting the vacuum module and the detection devices. By operating the opening and closing of the control valve, the vacuum module can be connected to one of the detection devices, thereby enabling the vacuum module to alternately draw vacuum from the sealed cavities of the two detection devices.

[0053] In this embodiment, a conveyor belt 8 is provided between the feeding mechanism 6 and the transmission guide rail 51, see [link / reference] Figure 2As shown, a detection lens 9 is provided between the feeding mechanism 6 and the conveyor belt 8. After the conveying head 711 of the loading mechanism 71 obtains the product to be inspected from the feeding mechanism 6, it carries the product to the detection lens 9 for scanning. Qualified products will be carried to the loading platform 1 located at the loading station 511, and unqualified products will be placed on the conveyor belt 8 and transported away from the equipment.
