Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to a pressure wake-up detection device. Background Technology

[0002] A Battery Management System (BMS) is primarily designed for the intelligent management and maintenance of individual battery cells, monitoring battery status, and preventing overcharging and over-discharging to extend battery life. A BMS typically includes a circuit board with an integrated pressure sensor for wake-up functionality. The circuit board, currently in sleep mode, is activated when the pressure sensor detects a pressure threshold, allowing the BMS to manage the battery.

[0003] Currently, during the manufacturing process of BMS, the wake-up function of the circuit board is easily affected by manufacturing process reasons, resulting in a low yield of the finished BMS product. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a pneumatic wake-up detection device that can improve the yield of BMS finished products.

[0005] This application is achieved through the following technical solution.

[0006] This application provides a pressure wake-up detection device for testing the wake-up function of a circuit board assembly used in the manufacture of a battery management system. The circuit board assembly includes a housing and a circuit board housed within the housing. The pressure wake-up detection device includes a detection box, which includes: a sealed cavity for accommodating the circuit board assembly; and a pressure adjustment and detection structure for adjusting and detecting the pressure within the sealed cavity to detect whether the circuit board assembly can be woken up, and, if woken up, detecting whether the pressure within the sealed cavity is within a set pressure range when woken up.

[0007] The pneumatic wake-up detection device provided in this application performs wake-up detection on the circuit board assembly. First, the circuit board assembly is placed in the sealed cavity of the detection chamber. Second, the air pressure in the sealed cavity is increased by the air pressure adjustment detection structure. If the circuit board assembly is woken up during the increase, the air pressure adjustment detection structure obtains the air pressure in the sealed cavity at the time of wake-up and then determines whether the obtained air pressure is within the set air pressure range. If it is, the wake-up function of the circuit board assembly is normal; if not, the wake-up function of the circuit board assembly is abnormal. If the circuit board assembly is still not woken up when the air pressure in the sealed cavity increases to the upper limit of the set air pressure range, the wake-up function of the circuit board assembly is abnormal. In this way, the pneumatic wake-up detection device can detect the pneumatic wake-up function of the circuit board assembly, and can intercept abnormal circuit board assemblies in time during the manufacturing process of BMS, reducing the probability of abnormal circuit board assemblies flowing to subsequent processes, thereby improving the yield of BMS finished products. It also saves the parts and time used by abnormal circuit board assemblies in subsequent processes, thereby reducing material and time waste, reducing costs, and improving production efficiency.

[0008] In some embodiments, the air pressure regulation detection structure includes: an air injection port formed in the detection box and connected to the sealing cavity, the air injection port being used to allow gas to enter the sealing cavity; and an exhaust port formed in the detection box and connected to the sealing cavity, the exhaust port being used to allow air pressure in the sealing cavity to be discharged.

[0009] The air pressure inside the sealed cavity can be regulated through the air injection port and the air vent. The air injection port allows external gas to enter the sealed cavity, thereby increasing its internal air pressure, which is especially important for simulating high-pressure environments. The air vent is used to expel the gas from the sealed cavity, ensuring that the air pressure inside the sealed cavity remains at a safe level, guaranteeing the air pressure accuracy of the sealed cavity and the safety of personnel.

[0010] In some embodiments, the air pressure regulation and detection structure includes a pressure detection element for detecting the air pressure inside the sealed cavity.

[0011] The pressure detection device is used to detect the air pressure inside the sealed cavity. During the increase of air pressure, the device continuously monitors the detected air pressure. If the circuit board assembly is activated before the air pressure reaches the upper limit of the set pressure range, the air pressure at the time of activation is acquired. Then, it is determined whether the acquired air pressure is within the set pressure range. If it is, the circuit board assembly's activation function is normal; otherwise, it is abnormal. If the circuit board assembly still does not activate when the air pressure reaches the upper limit of the set pressure range, its activation function is abnormal. Thus, by setting up the pressure detection device, the device can detect the activation function of the circuit board assembly.

[0012] In some embodiments, the detection box includes: a box body having a first opening; and a sealing cover that can be opened and closed to seal the first opening, forming a sealed cavity with the box body.

[0013] Thus, the first opening is used for the insertion and removal of the circuit board assembly, facilitating its placement and removal. The sealing cover is used to seal the first opening of the main body of the box, forming a sealed cavity, to regulate the air pressure around the circuit board assembly contained within the sealed cavity, thereby detecting the wake-up function of the circuit board assembly.

[0014] In some embodiments, the testing box further includes a carrier plate that can be accommodated within the sealed cavity. The carrier plate has a support station for supporting the circuit board assembly. The support station is provided with a positioning structure for positioning the circuit board assembly at the support station.

[0015] In this way, the precise positioning of the circuit board assembly within the sealed cavity is achieved through the carrier plate and positioning structure. This not only facilitates the rapid installation of the circuit board assembly but also reduces detection errors caused by inaccurate positioning, thereby improving the reliability and operational efficiency of the pneumatic wake-up detection device.

[0016] In some embodiments, the positioning structure includes at least one positioning block connected to the carrier plate. The positioning block includes a first positioning surface extending along a first direction and a second positioning surface extending along a second direction intersecting the first direction. The first positioning surface and the second positioning surface are used to abut against two adjacent side surfaces of the circuit board assembly, respectively.

[0017] By using intersecting first and second positioning surfaces to abut against two adjacent sides of the circuit board assembly, precise positioning of the circuit board assembly in three-dimensional space is achieved. This positioning method is more stable and reliable than single-point or single-sided positioning, effectively reducing the probability of displacement or rotation of the circuit board assembly during installation or testing, thereby improving the accuracy of wake-up detection.

[0018] In some embodiments, four positioning blocks are provided, arranged around the bearing station, for respectively abutting the four corners of the circuit board assembly.

[0019] By precisely positioning the four corners of the circuit board assembly using four positioning blocks, the likelihood of displacement or tilting during installation or testing can be reduced. Each positioning block provides support and fixation; the four blocks work together to stably hold the circuit board assembly in its bearing position, preventing easy movement due to external factors. Furthermore, the arrangement of the four positioning blocks improves installation accuracy, making it easier to align the circuit board assembly with the positioning blocks and ensuring it is in the correct position. This accuracy is crucial for subsequent testing, reducing operational errors and inaccuracies caused by inaccurate positioning.

[0020] In some embodiments, the positioning block is configured to be positionally adjustable relative to the carrier plate along the first direction; and / or, the positioning block is configured to be positionally adjustable relative to the carrier plate along the second direction.

[0021] In this way, the position of the positioning block can be flexibly adjusted according to the actual size and shape of the circuit board assembly. The positioning block can be precisely adjusted along the first and / or second direction, allowing the circuit board assembly to be stably and accurately positioned on the support station. This adjustability greatly improves the adaptability of the device, enabling the same device to be used for circuit board assemblies of different sizes and shapes, increasing the utilization rate and flexibility of the device, and expanding its application range.

[0022] In some embodiments, the carrier plate is provided with connecting structures spaced apart along the first direction and / or the second direction, and the positioning block may be selectively connected to any of the connecting structures.

[0023] The connecting structures are spaced apart along the first and / or second directions, providing multiple selectable connection points for the positioning blocks. Therefore, the connection points of the positioning blocks can be flexibly selected according to the actual size and shape of the circuit board assembly, enabling the positioning blocks to accurately position the circuit board assembly. Furthermore, due to the spaced distribution of the connecting structures and the selective connection of the positioning blocks, the same pneumatic wake-up detection device can be used for circuit board assemblies of different sizes and shapes without replacing the entire carrier board or making complex structural adjustments. This not only saves costs but also improves the utilization rate and flexibility of the device.

[0024] In some embodiments, the connection structure includes at least one first connection hole formed in the carrier plate, and the positioning block is connected to the at least one first connection hole by a first fastener.

[0025] Thus, the positioning block can be securely mounted on the carrier plate using a simple first fastener connection. The formation of the first connecting hole allows for more precise positioning of the positioning block, while the use of the first fastener also improves the stability of the connection. Furthermore, the positioning block can be more easily disassembled and installed using the first fastener connection method, which not only simplifies the operation process but also improves connection efficiency.

[0026] In some embodiments, the positioning structure includes at least one positioning post connected to the carrier plate, the positioning post being used to insert into the positioning hole of the circuit board assembly.

[0027] In this way, the positioning pins are precisely inserted into the positioning holes of the circuit board assembly, thereby improving the accuracy and stability of the circuit board assembly's positioning on the carrier board.

[0028] In some embodiments, the carrier plate and the sealing cover are fixedly connected, and the detection box further includes a first driving member disposed on the box body. The carrier plate and / or the sealing cover are connected to the output end of the first driving member. The carrier plate and the sealing cover can reciprocate along a first direction under the action of the first driving member to switch between a sealed state and an open state. In the sealed state, the sealing cover closes the first opening and the carrier plate is located in the sealed cavity. In the open state, the sealing cover is away from the first opening and the carrier plate is located at a position where its bearing position is outside the first opening.

[0029] Thus, in the sealed state, the circuit board assembly positioned on the carrier plate is housed within the sealed cavity, allowing for detection of the circuit board assembly's wake-up function by changing the air pressure within the sealed cavity. In the open state, the sealing cover is away from the first opening, and the carrier plate is positioned outside the first opening at its bearing station, facilitating various operations at the carrier plate's bearing station without opening the entire housing body. This optimizes the workflow and reduces unnecessary interference and energy consumption. Furthermore, the automatic reciprocating movement of the carrier plate and sealing cover along the first direction via the first drive component enables rapid switching between the sealed and open states, improving operational efficiency, reducing human error and uncertainty, and thereby enhancing the reliability and stability of the device.

[0030] In some embodiments, in the open state, the outer wall of the housing body and the sealing cover form a second opening opposite to the bearing station. The second opening is for the circuit board assembly to pass through, so that the circuit board assembly is placed in or removed from the bearing station.

[0031] A second opening formed between the outer wall of the housing and the sealing cover provides a dedicated channel for the circuit board assembly. This channel allows the circuit board assembly to pass smoothly through and be placed on or removed from the support station. This design not only simplifies the installation and removal of the circuit board assembly but also improves operational convenience. Furthermore, the ease of access for the circuit board assembly enhances production efficiency, making the entire operation smoother and more efficient.

[0032] In some embodiments, one of the box body and the carrier plate is provided with a slider, and the other is provided with a slide rail extending along the first direction, and the slider is slidably connected to the slide rail.

[0033] The sliding connection between the slider and the slide rail allows the carrier plate and the sealing cover to move smoothly along the first direction. Furthermore, the sliding of the slider on the slide rail enables rapid positioning and alignment of the box body and the carrier plate, thus improving the operational efficiency of closing or opening the first opening with the sealing cover. Simultaneously, the sliding connection method also makes the device easier to maintain and reduces maintenance costs.

[0034] In some embodiments, the slider is connected to the inner wall of the box body, and the slide rail is connected to the carrier plate. In the sealed state, the slide rail is accommodated in the sealed cavity; in the open state, a portion of the slide rail extends out of the box body through the first opening.

[0035] In the sealed state, the slide rail is housed within the sealed cavity, preventing it from occupying the first opening. This allows the sealing cover to seal the first opening. In the open state, a portion of the slide rail extends out of the main body through the first opening, causing at least a portion of the carrier plate to extend out of the main body. This keeps the first opening open and positions the carrier plate in a location that facilitates the placement and removal of the circuit board assembly. This improves the smoothness and reliability of the pneumatic wake-up detection device's wake-up function for detecting the circuit board assembly.

[0036] In some embodiments, the air pressure wake-up detection device further includes a base, the main body of the box is fixedly connected to the base, and the sealing cover is slidably connected to the base along the first direction.

[0037] The base, serving as the fundamental support structure of the entire pneumatic wake-up detection device, provides stable support for the device by being fixed to the main body of the housing. The sealing cover is slidably connected to the base along the first direction, which improves the smoothness of the sealing cover's movement along the first direction and also facilitates the accuracy of the alignment between the sealing cover and the main body of the housing, thereby improving the sealing performance of the sealing cavity. Good sealing performance helps to improve the stability of air pressure changes within the sealing cavity, thus improving the accuracy and reliability of pneumatic wake-up detection.

[0038] In some embodiments, one of the base and the sealing cover is provided with a sliding groove, and the other is provided with a sliding block, the sliding block being slidably connected to the sliding groove along the first direction.

[0039] The sliding connection between the sliding block and the sliding groove allows the sealing cover to slide easily along the first direction on the base, thereby improving the smoothness of the sealing cover's movement, facilitating the opening and closing of the first opening, improving the smoothness of the operation, and increasing the efficiency of the operation.

[0040] In some embodiments, the detection box further includes a sealing and locking assembly, which includes a locking block configured to press against the sealing cover from the side of the sealing cover away from the sealing cavity when the sealing cover closes the first opening.

[0041] The locking block presses against the back of the sealing cover, ensuring a tight fit between the sealing cover and the main body of the box, improving the sealing performance of the sealing cavity. Good sealing performance helps to improve the stability of air pressure changes in the sealing cavity, and improves the accuracy and reliability of air pressure wake-up detection.

[0042] In some embodiments, the sealing and locking assembly further includes a second driving member disposed on the housing body, and the locking block is connected to the output end of the second driving member. The locking block is capable of rotating around the first direction under the action of the second driving member between a position pressing against the sealing cover and a position avoiding the moving trajectory of the sealing cover along the first direction.

[0043] By driving the locking block to rotate around the first direction using the second driving component, the locking block can quickly change from a position avoiding the sealing cover's movement trajectory to a position pressing against the sealing cover. This reduces manual operation steps and time, improving operational efficiency. Therefore, the combination of the second driving component and the locking block not only improves the sealing performance of the sealing cavity but also enhances the efficiency of the inspection operation.

[0044] In some embodiments, at least two sealing and locking components are provided, with at least one sealing and locking component located on one side of the box body along the second direction and at least one sealing and locking component located on the other side of the box body along the second direction, wherein the second direction intersects the first direction with each other.

[0045] Thus, by providing sealing and locking components on both sides of the main body of the box along the second direction, the sealing cover can be pressed against both ends along the second direction by the locking blocks, further improving the sealing performance of the sealing cover sealing the first opening.

[0046] In some embodiments, the box body includes a bottom plate located below the sealed cavity, and the first opening is formed on one side of the box body along the first direction, the first direction intersecting with a direction perpendicular to the inner wall of the bottom plate.

[0047] In this way, less energy is required to overcome gravity when the sealing cover and the carrier plate reciprocate along the first direction, and in some cases, no energy is required to overcome gravity, thus reducing the energy consumption during the opening and closing operation of the first opening.

[0048] In some embodiments, the base plate is formed with an injection hole and an exhaust hole, the injection hole being used to allow gas to enter the sealed cavity, and the exhaust hole being used to allow the air pressure in the sealed cavity to be discharged; the base plate is provided with a pressure detection element, the pressure detection element being used to detect the air pressure in the sealed cavity.

[0049] By placing the air injection port, air vent, and pressure sensor on the base plate, and positioning them close to the circuit board assembly positioned on the carrier plate, the circuit board assembly can more promptly sense pressure changes when the air pressure inside the sealed cavity is adjusted through the air injection and air vents, thus triggering a timely wake-up response. Furthermore, the pressure sensor's ability to detect pressure changes promptly and accurately improves the reliability of the wake-up detection.

[0050] In some embodiments, the air pressure wake-up detection device further includes a connector docking module disposed within the housing body. The connector docking module includes a connector fixing block connected to the base plate and a docking connector connected to the connector fixing block. In the sealed state, the docking connector is connected to the connector of the circuit board assembly carried on the bearing station.

[0051] The mating connector is aligned with the connector of the circuit board assembly mounted on the support station, enabling the mating connector to conduct current to the connector of the circuit board assembly, thereby powering the circuit board assembly and waking it up, ensuring the smooth progress of the circuit board assembly wake-up detection.

[0052] In some embodiments, the inner wall of the base plate is provided with a mounting base, the connector fixing block is mounted on the mounting base, and the position of the connector fixing block relative to the mounting base along the first direction is adjustable.

[0053] The mounting base enables the connector fixing block to be installed and fixed on the base plate. The position of the connector fixing block relative to the mounting base along the first direction is adjustable, allowing for flexible and precise adjustment of the position of the mating connector. This improves the accuracy of the mating between the connector and the circuit board assembly. Furthermore, by adjusting the connector fixing block along the first direction, it can be used to assemble circuit board assemblies with different dimensions along the first direction, increasing the flexibility of the device and expanding its applicability.

[0054] In some embodiments, the mounting base has second connecting holes spaced apart sequentially along the first direction, the connector fixing block has a third connecting hole, the third connecting hole is connected to the second connecting hole by a second fastener, and the position of the mating connector along the first direction can be adjusted by changing the second connecting hole connected to the third connecting hole.

[0055] Thus, by changing the second connecting hole connected to the third connecting hole, the position of the mating connector along the first direction can be easily adjusted, thereby improving the mating accuracy between the mating connector and the circuit board assembly. This also allows for mating with circuit board assemblies of different dimensions along the first direction, increasing the device's flexibility and expanding its applicability. Furthermore, this connection structure is simple to operate; the position of the mating connector can be quickly adjusted by selecting different second connecting holes without complex positioning or calibration operations, saving connection time and labor costs. Additionally, this connection method facilitates the overall assembly and disassembly of the connector mating module, allowing for the replacement of different models of connector mating modules to mate with different models of circuit board assemblies, further expanding the device's applicability.

[0056] In some embodiments, the third connection hole is a strip-shaped hole extending along the first direction.

[0057] If the position of the second fastener relative to the strip hole along the first direction can be adjusted, the position of the mating connector along the first direction can be finely adjusted, improving the accuracy of the mating connector position adjustment, thereby further improving the mating accuracy of the mating connector and the connector of the circuit board assembly.

[0058] In some embodiments, the pneumatic wake-up detection device further includes a barcode scanning mechanism, which includes a barcode scanner for scanning the identification code of the circuit board assembly carried on the carrying station.

[0059] By scanning the identification code on the circuit board assembly using a barcode scanner, relevant information about the circuit board assembly can be quickly obtained. This step greatly improves inspection efficiency, reduces the error rate of manual input, and thus ensures the accuracy of subsequent inspection steps.

[0060] In some embodiments, the box body includes a bottom plate and a top plate disposed opposite each other along a third direction intersecting the first direction. The bottom plate is located below the top plate. The scanning mechanism further includes a third driving member disposed on the side of the top plate facing away from the bottom plate. The barcode scanner is connected to the output end of the third driving member and can reciprocate between an extended position and a retracted position along the first direction under the action of the third driving member. In the retracted position, the projection of the barcode scanner lens along the third direction falls entirely within the projection range of the top plate. In the extended position, the barcode scanner lens extends beyond the edge of the top plate along the first direction, and in the open state, the scanning range of the barcode scanner lens fully covers the identification code.

[0061] When retracted, the barcode scanner's lens is positioned directly above the top panel. In this position, the scanner occupies minimal space along the first direction, reducing space requirements and facilitating storage and relocation. When scanning is needed, the scanner's lens can fully cover the identification code, thus enabling the scanner to scan the circuit board assembly's identification code and obtain relevant information about the circuit board assembly.

[0062] In some embodiments, the third drive member is mounted on the top plate via a mounting assembly, and the position of the third drive member relative to the top plate along the first direction is adjustable.

[0063] By installing the components, the position of the third drive unit relative to the top plate along the first direction can be adjusted. With a fixed drive stroke of the third drive unit, adjusting its position can change the extension and retraction positions of the barcode scanner, thus making it suitable for scanning identification codes at different locations, and further suitable for scanning circuit board assemblies of different sizes, expanding its application range.

[0064] In some embodiments, the mounting assembly includes a mounting rail, a connecting slider, and a locking member. The mounting rail extends along the first direction and is fixed to the top plate. The connecting slider has a sliding hole and is slidably fitted onto the mounting rail through the sliding hole. The third driving member is mounted on the connecting slider and can move with the connecting slider. The locking member is connected to the connecting slider and can lock the connecting slider onto the mounting rail.

[0065] This enables the position adjustment of the third drive component, expanding the applicability of the device. Furthermore, the mounting assembly used to adjust and install the third drive component has a simple structure, is easy to operate, and saves material and time costs.

[0066] In some embodiments, the locking member includes a threaded post and a handle connected to one end of the threaded post, the connecting slider is formed with a threaded hole communicating with the sliding hole, the end of the threaded post away from the handle is threadedly connected to the threaded hole, and is able to abut against the mounting guide rail when the handle is rotated.

[0067] In this way, the locking component is used to lock the connecting slider to the mounting rail. Moreover, the locking component has a simple structure, and the locking and unlocking operations are simple and convenient.

[0068] The beneficial effects of the embodiments disclosed herein include: this application provides a pressure wake-up detection device that can improve the yield of BMS finished products. Attached Figure Description

[0087] The following is a detailed description of this application.

[0088] Currently, new energy batteries are being used more and more widely in daily life and industry. They are not only used in energy storage systems for hydropower, thermal power, wind power, and solar power plants, but also extensively in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in aerospace and other fields. With the continuous expansion of the application areas of power batteries, the market demand is also constantly increasing.

[0089] To extend battery life, batteries are equipped with a Battery Management System (BMS), also known as a battery caretaker or battery manager. Its main function is to intelligently manage and maintain each battery cell, monitor battery status, and prevent overcharging and over-discharging, thereby extending battery life. A BMS typically consists of a circuit board and a housing covering the board. The circuit board is a printed circuit board formed using surface mount technology (SMT). This board integrates a pressure sensor for wake-up functionality. The circuit board, in dormant mode, is awakened when the pressure sensor detects a pressure threshold, enabling the BMS to perform battery detection, management, control, and protection operations.

[0090] Currently, during the circuit board assembly process, manufacturing process factors can easily lead to abnormal wake-up functionality in the resulting circuit board assembly. Factors affecting wake-up functionality include: first, damage to the pressure sensor during circuit board handling; second, failure to attach Mylar film to the pressure sensor's vents before conformal coating, causing the varnish to clog the vents and malfunctioning the sensor's ability to sense ambient air pressure; and third, failure to remove Mylar film from the pressure sensor's vents after conformal coating, resulting in blockage and malfunction of the sensor. The inventors of this application have discovered that existing BMS manufacturing processes lack a wake-up function detection step after circuit board assembly. Therefore, the inability to promptly identify abnormal circuit board assemblies after this step affects the yield of the finished BMS product, resulting in wasted materials and time.

[0091] The inventors of this application discovered through research that by setting up a process to detect the wake-up function of the circuit board assembly after the circuit board housing process, abnormal circuit board assemblies can be detected in a timely manner, making it easier to intercept abnormal circuit board assemblies, reducing the probability of abnormal circuit board assemblies flowing to subsequent processes, thereby improving the yield of BMS finished products. It also saves the parts and time used by abnormal circuit board assemblies in subsequent processes, thereby reducing the waste of materials and time, and thus reducing costs and improving production efficiency.

[0092] Based on this design concept, the inventors of this application have designed a pneumatic wake-up detection device. The pneumatic wake-up detection device is used to perform wake-up function detection on the circuit board assembly used to manufacture a battery management system (BMS). The circuit board assembly includes a housing and a circuit board housed in the housing. The pneumatic wake-up detection device includes a detection box, which includes a sealed cavity and a pneumatic pressure regulating detection structure. The sealed cavity is used to house the circuit board assembly. The pneumatic pressure regulating detection structure is used to regulate and detect the pneumatic pressure in the sealed cavity to detect whether the circuit board assembly can be woken up. In the case of being woken up, it detects whether the pneumatic pressure in the sealed cavity is within the set pneumatic pressure range.

[0093] During testing, the circuit board assembly is first placed into the sealed cavity of the testing chamber. Then, the air pressure inside the sealed cavity is increased using an air pressure regulating detection structure. If the circuit board assembly is activated during this pressure increase, the air pressure inside the sealed cavity at the time of activation is recorded using the air pressure regulating detection structure. The system then determines whether the recorded air pressure is within the set pressure range. If it is, the circuit board assembly's activation function is normal; otherwise, it is abnormal. If the circuit board assembly still does not activate when the air pressure inside the sealed cavity increases to the upper limit of the set pressure range, the activation function is abnormal, and the pressure increase operation is stopped. In this way, the air pressure activation detection device can detect the air pressure activation function of the circuit board assembly. This allows for the timely interception of abnormal circuit board assemblies during BMS manufacturing, reducing the likelihood of abnormal circuit board assemblies flowing to subsequent processes, thereby improving the yield of the finished BMS product. It also saves on the components and time used in subsequent processes for abnormal circuit board assemblies, reducing material and time waste, lowering costs, and improving production efficiency.

[0097] In some embodiments of this application, for ease of explanation, a first direction, a second direction, and a third direction are defined. These three directions intersect each other; here, intersecting each other includes perpendicularly intersecting each other. For ease of understanding of the embodiments of this application, in... Figures 2 to 7 In the illustrated embodiments, the first direction, the second direction, and the third direction are given as examples where they intersect each other perpendicularly. However, those skilled in the art should understand that the embodiments of this application are not limited to the case where these three directions intersect each other perpendicularly. For ease of explanation, as follows... Figures 2 to 7 As shown by the arrows, the direction of arrow X is the first direction, the direction of arrow Y is the second direction, and the direction of arrow Z is the third direction. Sometimes, the direction that arrow Z points in along the third direction is called "up," and its opposite direction is called "down."

[0098] Figures 1 to 7 As shown, this application provides a pressure wake-up detection device for detecting the wake-up function of a circuit board assembly 100 used to manufacture a battery management system (BMS). The circuit board assembly 100 includes a housing 10 and a circuit board housed within the housing 10. The pressure wake-up detection device includes a detection box 1, which includes a sealed cavity 19 and a pressure regulation and detection structure 2. The sealed cavity 19 is used to house the circuit board assembly 100. The pressure regulation and detection structure 2 is used to regulate and detect the pressure inside the sealed cavity 19 to detect whether the circuit board assembly 100 can be woken up, and to detect whether the pressure inside the sealed cavity 19 is within a set pressure range when the circuit board assembly 100 is woken up.

[0099] It should be noted that the outer casing 10 covering the circuit board assembly 100 is not sealed. That is, the casing wall of the outer casing 10 has gaps or holes communicating with the inner cavity of the outer casing 10. Therefore, when the air pressure in the sealed cavity 19 changes, the gas in the sealed cavity 19 will enter the outer casing 10, thereby changing the air pressure in the outer casing 10. Consequently, the circuit board assembly 100 contained in the sealed cavity 19 will be woken up when it is functioning normally. Therefore, the wake-up function of the circuit board assembly 100 can be tested by changing the air pressure in the sealed cavity 19.

[0100] The circuit board assembly 100 is woken up using the air pressure wake-up detection device provided in this application embodiment. First, the circuit board assembly 100 is placed in the sealed cavity 19 of the detection box 1. Second, the air pressure in the sealed cavity 19 is increased by the air pressure adjustment detection structure 2. If the circuit board assembly 100 is woken up during the increase, the air pressure adjustment detection structure 2 obtains the air pressure in the sealed cavity 19 when it is woken up, and then determines whether the obtained air pressure is within the set air pressure range. If it is, the wake-up function of the circuit board assembly 100 is normal; if not, the wake-up function of the circuit board assembly 100 is abnormal. If the circuit board assembly 100 is still not woken up when the air pressure in the sealed cavity 19 is increased to the upper limit of the set air pressure range, the wake-up function of the circuit board assembly 100 is abnormal. Thus, the pneumatic wake-up detection device can detect the pneumatic wake-up function of the circuit board assembly 100, and can promptly intercept abnormal circuit board assemblies 100 during the manufacturing process of BMS, reducing the probability of abnormal circuit board assemblies 100 flowing to subsequent processes, thereby improving the yield of BMS finished products. It also saves the parts and time used in subsequent processes for abnormal circuit board assemblies 100, thereby reducing the waste of materials and time, reducing costs, and improving production efficiency.

[0101] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the test box 1 includes a box body 11 and a sealing cover 12. The box body 11 has a first opening 111. The sealing cover 12 can be opened and closed to seal the first opening 111, forming a sealed cavity 19 with the box body 11.

[0102] It should be noted that when the sealing cap 12 is placed over the first opening 111, it means that the sealing cap 12 is placed over the first opening 111 and seals the first opening 111.

[0103] During the air pressure wake-up test, the circuit board assembly 100 enters the interior of the housing body 11 through the first opening 111. Then, the sealing cover 12 seals the first opening 111, so that the space inside the housing body 11 forms a sealed cavity 19. After that, the air pressure in the sealed cavity 19 is adjusted by the air pressure adjustment detection structure 2 to test the wake-up function of the circuit board assembly 100.

[0104] Thus, the first opening 111 is used for the insertion and removal of the circuit board assembly 100, facilitating the placement and removal of the circuit board assembly 100. The sealing cover 12 is used to cover the first opening 111 of the main body 11 to form a sealed cavity 19, so as to regulate the air pressure around the circuit board assembly 100 contained in the sealed cavity 19, thereby detecting the wake-up function of the circuit board assembly 100.

[0105] In some embodiments of this application, such as Figure 2 and Figure 3As shown, the testing box 1 also includes a carrier plate 13, which can be accommodated in the sealed cavity 19. The carrier plate 13 has a bearing station for bearing the circuit board assembly 100. The bearing station is provided with a positioning structure 14, which is used to position the circuit board assembly 100 in the bearing station.

[0106] During the air pressure wake-up test, the circuit board assembly 100 is positioned on the carrier plate 13 by the positioning structure 14, and the carrier plate 13 is accommodated in the sealed cavity 19, so that the circuit board assembly 100 is placed in a predetermined position in the sealed cavity 19, thereby realizing the positioning of the circuit board assembly 100 in the sealed cavity 19.

[0107] In this way, the carrier plate 13 and the positioning structure 14 achieve precise positioning of the circuit board assembly 100 in the sealed cavity 19, which not only helps the circuit board assembly 100 to be installed quickly, but also reduces detection errors caused by inaccurate positioning, and improves the reliability and operating efficiency of the pneumatic wake-up detection device.

[0108] In some embodiments of this application, such as Figure 5 and Figure 6 As shown, the positioning structure 14 includes at least one positioning block 141 connected to the carrier plate 13. The positioning block 141 includes a first positioning surface 1411 extending along a first direction X and a second positioning surface 1412 extending along a second direction Y intersecting the first direction X. The first positioning surface 1411 and the second positioning surface 1412 are used to abut against two adjacent side surfaces of the circuit board assembly 100, respectively.

[0109] It is understood that both the first direction X and the second direction Y intersect each other with directions perpendicular to the bearing surface of the carrier plate 13. Intersection includes perpendicular intersection.

[0110] By using the intersecting first positioning surface 1411 and second positioning surface 1412 to abut against two adjacent sides of the circuit board assembly 100, precise positioning of the circuit board assembly 100 in three-dimensional space is achieved. This positioning method is more stable and reliable than single-point or single-sided positioning, and can effectively reduce the probability of displacement or rotation of the circuit board assembly 100 during installation or testing, thereby improving the accuracy of wake-up detection.

[0111] In some embodiments of this application, such as Figure 5 and Figure 6 As shown, there are four positioning blocks 141 arranged around the bearing station to abut the four corners of the circuit board assembly 100 respectively.

[0112] By precisely positioning the four corners of the circuit board assembly 100 using four positioning blocks 141, the likelihood of displacement or tilting during installation or testing can be reduced. Each positioning block 141 provides support and fixation; the combined action of the four blocks ensures the circuit board assembly 100 is stably fixed in its bearing position, preventing easy movement due to external factors. Furthermore, the arrangement of the four positioning blocks 141 improves installation accuracy. It makes it easier to align the circuit board assembly 100 with the positioning blocks 141, ensuring the assembly is in the correct position. This accuracy is crucial for subsequent testing, reducing operational errors and inaccuracies caused by inaccurate positioning.

[0113] In some embodiments of this application, such as Figure 4 and Figure 5 As shown, the positioning block 141 is configured to be adjustable in position relative to the carrier plate 13 along the first direction X; and / or, the positioning block 141 is configured to be adjustable in position relative to the carrier plate 13 along the second direction Y.

[0114] In this way, the position of the positioning block 141 can be flexibly adjusted according to the actual size and shape of the circuit board assembly 100. The positioning block 141 can be precisely adjusted along the first direction X and / or the second direction Y, so that the circuit board assembly 100 can be stably and accurately positioned on the bearing station. This adjustability greatly improves the adaptability of the device, enabling the same device to be used for circuit board assemblies 100 of different sizes and shapes, increasing the utilization rate and flexibility of the device, and expanding its application range.

[0115] In some embodiments of this application, such as Figure 4 and Figure 5 As shown, the carrier plate 13 is provided with connecting structures 131 spaced apart along the first direction X and / or the second direction Y, and the positioning block 141 can be selectively connected to any of the connecting structures 131.

[0116] The connecting structures 131 are spaced apart along the first direction X and / or the second direction Y, providing multiple optional connection points for the positioning blocks 141. Therefore, the connection points of the positioning blocks 141 can be flexibly selected according to the actual size and shape of the circuit board assembly 100, enabling the positioning blocks 141 to accurately position the circuit board assembly 100. Furthermore, due to the spaced distribution of the connecting structures 131 and the selective connection of the positioning blocks 141, the same pneumatic wake-up detection device can be used for circuit board assemblies 100 of different sizes and shapes without replacing the entire carrier board 13 or making complex structural adjustments. This not only saves costs but also improves the utilization rate and flexibility of the device.

[0117] In some embodiments of this application, such as Figure 4 and Figure 5 As shown, the connection structure 131 includes at least one first connection hole 131a formed on the carrier plate 13, and the positioning block 141 is connected to at least one first connection hole 131a by a first fastener.

[0118] For example, the first fastener includes, but is not limited to, bolts, screws, rivets, etc.

[0119] Thus, the positioning block 141 can be securely installed on the carrier plate 13 through a simple first fastener connection. The formation of the first connecting hole 131a makes the installation position of the positioning block 141 more precise, and the use of the first fastener also improves the stability of the connection. In addition, the positioning block 141 can be more easily disassembled and installed through the first fastener connection method, which not only simplifies the operation process but also improves the connection efficiency.

[0120] In some embodiments of this application, such as Figure 1 and Figure 6 As shown, the positioning structure 14 includes at least one positioning post 142, which is connected to the carrier plate 13 and is used to insert into the positioning hole 30 of the circuit board assembly 100.

[0121] For example, the carrier board 13 is provided with four positioning posts 142, and the circuit board assembly 100 is provided with four positioning holes 30. The four positioning posts 142 are inserted into the four positioning holes 30 in a one-to-one correspondence.

[0122] Thus, the positioning pin 142 is precisely inserted into the positioning hole 30 of the circuit board assembly 100, thereby improving the accuracy and firmness of the positioning of the circuit board assembly 100 on the carrier board 13.

[0123] In some embodiments of this application, such as Figures 3 to 6 As shown, the carrier plate 13 and the sealing cover 12 are fixedly connected. The test box 1 also includes a first driving member (not shown in the figure) disposed on the box body 11. The carrier plate 13 and / or the sealing cover 12 are connected to the output end of the first driving member. The carrier plate 13 and the sealing cover 12 can reciprocate along the first direction X under the action of the first driving member to switch between a sealed state and an open state. In the sealed state, the sealing cover 12 closes the first opening 111 and the carrier plate 13 is located in the sealed cavity 19. In the open state, the sealing cover 12 is away from the first opening 111 and the carrier plate 13 is located at a position where its bearing position is outside the first opening 111.

[0124] For example, the first drive element may be, but is not limited to, a linear motor or a linear cylinder.

[0125] It is understandable that "in the open state, the sealing cover 12 is away from the first opening 111 and the carrier plate 13 is located outside the first opening 111" means that in the open state, the sealing cover 12 and the first opening 111 are spaced apart along the first direction X, that is, the first opening 111 is open. Furthermore, at least a portion of the carrier plate 13 is located outside the first opening 111 and all of the carrier plate 13's bearing positions are located outside the first opening 111. "Bearing positions are located outside the first opening 111" means that all bearing positions are located on the side of the first opening 111 facing away from the sealing cavity 19.

[0126] Thus, in the sealed state, the sealing cover 12 seals the first opening 111, forming a highly airtight sealed cavity 19, and the carrier plate 13 is located inside the sealed cavity 19. Therefore, the circuit board assembly 100, positioned on the carrier plate 13, is accommodated within the sealed cavity 19, allowing the detection of the wake-up function of the circuit board assembly 100 to be achieved by changing the air pressure within the sealed cavity 19. In the open state, the sealing cover 12 is away from the first opening 111, and the carrier plate 13 is located with its bearing position outside the first opening 111. That is, the bearing position of the carrier plate 13 is on the side of the first opening 111 away from the sealed cavity 19. In other words, the bearing position is located outside the housing body 11. This facilitates various operations (such as installing and removing the circuit board assembly 100) on the bearing position of the carrier plate 13 without having to open the entire housing body 11. This optimizes the workflow and reduces unnecessary interference and energy consumption. In addition, the carrier plate 13 and the sealing cover 12 are automatically driven to reciprocate along the first direction X by the first driving component (such as a motor or cylinder), which realizes the rapid switching between the sealed state and the open state, improves the operating efficiency, reduces human error and uncertainty, and thus improves the reliability and stability of the device.

[0127] In some embodiments of this application, such as Figure 5 As shown, in the open state, the outer wall of the box body 11 and the sealing cover 12 form a second opening 18 opposite to the bearing station. The second opening 18 is used for the circuit board assembly 100 to pass through, so that the circuit board assembly 100 can be placed in or taken out of the bearing station.

[0128] A second opening 18, formed between the outer wall of the housing body 11 and the sealing cover 12, provides a dedicated channel for the circuit board assembly 100. This channel allows the circuit board assembly 100 to pass smoothly through and be placed on or removed from the support station. This design not only simplifies the installation and disassembly process of the circuit board assembly 100 but also improves operational convenience. Furthermore, the ease of entry and exit of the circuit board assembly 100 also increases production efficiency, making the entire operation smoother and more efficient.

[0129] In some embodiments of this application, such as Figure 5 As shown, in the open state, the outer wall of the box body 11 and the sealing cover 12 form two third openings opposite each other along the second direction Y. The third openings can be used for the circuit board assembly 100 to pass through, so that the circuit board assembly 100 can be placed in the support station or taken out from the support station.

[0130] In some embodiments of this application, such as Figure 4 and Figure 5 As shown, of the two components, the box body 11 and the carrier plate 13, one is provided with a slider 151 and the other is provided with a slide rail 152 extending along the first direction X. The slider 151 is slidably connected to the slide rail 152.

[0131] The sliding connection between slider 151 and slide rail 152 allows the carrier plate 13 and sealing cover 12 to move smoothly along the first direction X. Furthermore, the sliding of slider 151 on slide rail 152 enables rapid positioning and alignment of the box body 11 and carrier plate 13, thus improving the operational efficiency of sealing cover 12 in closing or opening the first opening 111. Simultaneously, the sliding connection method also makes device maintenance more convenient and reduces maintenance costs.

[0132] In some embodiments of this application, such as Figure 4 and Figure 5 As shown, a slider 151 is connected to the inner wall of the box body 11, and a slide rail 152 is connected to the carrier plate 13. In the sealed state, the slide rail 152 is accommodated in the sealed cavity 19; in the open state, part of the slide rail 152 extends out of the box body 11 through the first opening 111.

[0133] For example, the box body 11 includes a bottom plate 112 located below the sealed cavity 19, and a slider 151 is fixedly connected to the inner wall of the bottom plate 112.

[0134] In the sealed state, the slide rail 152 is accommodated within the sealed cavity 19, so that the slide rail 152 does not occupy the first opening 111, thereby allowing the sealing cover 12 to seal the first opening 111. In the open state, a portion of the slide rail 152 extends out of the housing body 11 through the first opening 111, causing at least a portion of the carrier plate 13 to extend out of the housing body 11, thus opening the first opening 111 and positioning the carrier plate 13 in a position that facilitates the placement and removal of the circuit board assembly 100. This improves the smoothness and reliability of the pneumatic wake-up detection device in detecting the wake-up function of the circuit board assembly 100.

[0135] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the air pressure wake-up detection device also includes a base 3, a box body 11 fixedly connected to the base 3, and a sealing cover 12 slidably connected to the base 3 along the first direction X.

[0136] The base 3 serves as the fundamental support structure for the entire pneumatic wake-up detection device, providing stable support for the device through its connection to the main body 11. The sealing cover 12 is slidably connected to the base 3 along the first direction X, improving the stability of the movement of the sealing cover 12 along the first direction X and also facilitating the accurate alignment of the sealing cover 12 with the main body 11. This improves the sealing performance of the sealing cavity 19, and the good sealing performance helps to improve the stability of air pressure changes within the sealing cavity 19, thereby enhancing the accuracy and reliability of the pneumatic wake-up detection.

[0137] For example, the base 3 has a first plate 31 on its top, the box body 11 is fixedly connected to the first plate 31, and the sealing cover 12 is slidably connected to the first plate 31 along the first direction X.

[0138] In some embodiments of this application, such as Figure 3 As shown, of the base 3 and the sealing cover 12, one has a sliding groove 161 and the other has a sliding block 162. The sliding block 162 is slidably connected to the sliding groove 161 along the first direction X.

[0139] For example, such as Figure 3 As shown, the first plate 31 of the base 3 has two sliding grooves 161 spaced apart along the second direction Y. The sliding grooves 161 extend along the first direction X. The sealing cover 12 is connected to two sliding blocks 162 on the side of the box body 11 facing away from it along the first direction X. The sliding blocks 162 are slidably connected to the sliding grooves 161 along the first direction X.

[0140] The sliding connection between the sliding block 162 and the sliding groove 161 allows the sealing cover 12 to slide easily along the first direction X on the base 3, thereby improving the smoothness of the movement of the sealing cover 12, facilitating the opening and closing of the first opening 111, improving the smoothness of the operation, and improving the efficiency of the operation.

[0141] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the test box 1 also includes a sealing and locking assembly 17, which includes a locking block 171. The locking block 171 is configured to press against the sealing cover 12 from the side of the sealing cover 12 away from the sealing cavity 19 when the sealing cover 12 covers the first opening 111.

[0142] The locking block 171 presses against the back of the sealing cover 12, which can ensure a tight fit between the sealing cover 12 and the box body 11, improve the sealing performance of the sealing cavity 19, and the good sealing performance helps to improve the stability of air pressure changes in the sealing cavity 19, and improve the accuracy and reliability of air pressure wake-up detection.

[0143] In some embodiments of this application, such as Figure 2 and Figure 3As shown, the sealing and locking assembly 17 also includes a second driving member 172. The second driving member 172 is disposed on the housing body 11. The locking block 171 is connected to the output end of the second driving member 172. Under the action of the second driving member 172, the locking block 171 can rotate around the first direction X between the position pressing against the sealing cover 12 and the position avoiding the sealing cover 12 along the movement trajectory of the first direction.

[0144] For example, the second drive element 172 may be, but is not limited to, a rotary motor or a rotary cylinder.

[0145] When the sealing cover 12 covers the first opening 111, the locking block 171 presses against the sealing cover 12 from the side of the sealing cover 12 away from the sealing cavity 19, improving the sealing performance of the sealing cavity 19. After the circuit board assembly 100 inside the sealing cavity 19 has been inspected, the second drive member 172 drives the locking block 171 to rotate to a position that avoids the movement trajectory of the sealing cover 12 along the first direction. That is, the locking block 171 will not block the movement of the sealing cover 12 along the first direction, so that the sealing cover 12 can move smoothly along the first direction X.

[0146] By driving the locking block 171 to rotate around the first direction X via the second driving member 172, the locking block 171 can quickly change from a position avoiding the moving trajectory of the sealing cover 12 to a position pressing against the sealing cover 12. This reduces the steps and time of manual operation and improves the efficiency of the operation. Therefore, the arrangement of the second driving member 172 and the locking block 171 not only improves the sealing performance of the sealing cavity 19, but also improves the efficiency of the inspection operation.

[0147] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, at least two sealing and locking components 17 are provided. At least one sealing and locking component 17 is provided on one side of the box body 11 along the second direction Y, and at least one sealing and locking component 17 is provided on the other side of the box body 11 along the second direction Y. The second direction Y intersects with the first direction X.

[0148] For example, there are two sealing and locking components 17, one of which is located on one side of the box body 11 along the second direction Y, and the other is located on the other side of the box body 11 along the second direction Y, the second direction Y intersecting the first direction X.

[0149] Thus, by providing sealing and locking components 17 on both sides of the main body 11 along the second direction Y, the sealing cover 12 can be pressed against both ends of the sealing cover 12 along the second direction Y by the locking blocks 171, further improving the sealing performance of the sealing cover 12 sealing the first opening 111.

[0150] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the box body 11 includes a bottom plate 112 located below the sealed cavity 19, and a first opening 111 is formed on one side of the box body 11 along a first direction X, the first direction X intersecting the direction perpendicular to the inner wall of the bottom plate 112.

[0151] Specifically, the direction perpendicular to the inner wall of the base plate 112 is the third direction Z, which includes the direction of gravity.

[0152] The base plate 112 is located below the sealing cavity 19, meaning that in the direction of gravity, the base plate 112 is located on the lower side of the sealing cavity 19. "The first direction X intersects with the direction perpendicular to the inner wall of the base plate 112" means that the first opening 111 is not located on the upper or lower wall of the box body 11, but on the four sides of the box body 11. That is, the sealing cover 12 covers the first opening 111 from the side of the box body 11. In this way, the sealing cover 12 and the carrier plate 13 require less energy to overcome gravity when moving back and forth along the first direction X, and in some cases, no energy is required to overcome gravity, thus reducing the energy consumption during the opening and closing operation of the first opening 111.

[0153] In some embodiments of this application, the first opening 111 is provided on the upper or lower wall of the box body 11, that is, the sealing cover 12 covers the first opening 111 from above or below the box body 11.

[0154] In some embodiments of this application, such as Figure 4 and Figure 5 As shown, the air pressure regulation and detection structure 2 includes an air injection port 21 and an air exhaust port 22. The air injection port 21 is formed in the detection box 1 and communicates with the sealing cavity 19. The air injection port 21 is used to allow gas to enter the sealing cavity 19 to increase the air pressure in the sealing cavity 19. The air exhaust port 22 is formed in the detection box 1 and communicates with the sealing cavity 19. The air exhaust port 22 is used to allow the air pressure in the sealing cavity 19 to be discharged to decrease the air pressure in the sealing cavity 19.

[0155] The air pressure inside the sealed cavity 19 can be adjusted through the air injection port 21 and the air exhaust port 22. The air injection port 21 allows external gas to enter the sealed cavity 19, thereby increasing its internal air pressure, which is especially important for simulating high-pressure environments. The air exhaust port 22 is used to discharge the gas inside the sealed cavity 19, ensuring that the air pressure inside the sealed cavity 19 is at a safe pressure, thus ensuring the air pressure accuracy of the sealed cavity 19 and the safety of personnel.

[0156] For example, the injection port 21 is connected to an injection pipeline and an injection pump connected to the injection pipeline on the side facing away from the sealing cavity 19. The injection pump is used to drive gas from the gas source through the injection pipeline and the injection port 21 into the sealing cavity 19 to increase the gas pressure inside the sealing cavity 19. The injection pipeline is equipped with a one-way valve that only allows gas to flow from the injection pump to the injection port 21. In this way, gas is injected into the sealing cavity 19 to increase the internal gas pressure, and the one-way valve makes it difficult for gas in the sealing cavity 19 to flow out through the injection port 21, reducing the possibility that the injection port 21 will affect the sealing performance of the sealing cavity 19.

[0157] For example, the vent 22 connects to an exhaust pipe and an exhaust pump connected to the exhaust pipe on the side facing away from the sealing cavity 19. The exhaust pump drives the gas in the sealing cavity 19 to flow outward through the vent 22 and the exhaust pipe to discharge the gas in the sealing cavity 19. The exhaust pipe is equipped with a one-way valve that only allows gas to flow from the vent 22 to the exhaust pump. In this way, the gas in the sealing cavity 19 is discharged to reduce the internal air pressure. When venting, the one-way valve opens, allowing the gas in the sealing cavity 19 to be discharged outward through the vent 22. When not venting, the one-way valve closes, reducing the possibility of gas in the sealing cavity 19 being discharged outward through the vent 22, thereby reducing the possibility that the vent 22 will affect the sealing performance of the sealing cavity 19.

[0158] In some embodiments of this application, such as Figure 4 and Figure 5 As shown, the air pressure regulation and detection structure 2 includes a pressure detection element 23, which is used to detect the air pressure in the sealed cavity 19.

[0159] For example, the pressure detection element 23 may be entirely disposed within the sealed cavity 19, or it may be partially located outside the sealed cavity 19 with the other part extending into the sealed cavity 19. For example, the wall surface of the box body 11 is formed with a pressure detection hole, and the detection head of the pressure detection element 23 extends into the sealed cavity 19 through the pressure detection hole to detect the pressure inside the sealed cavity 19.

[0160] For example, the pressure sensing element 23 can be, but is not limited to, a barometer, a pressure sensor, etc.

[0161] The pressure detection element 23 is used to detect the air pressure inside the sealed cavity 19. During the increase of air pressure, the pressure detected by the pressure detection element 23 is constantly monitored. If the circuit board assembly 100 is activated before the air pressure reaches the upper limit of the set air pressure range, the air pressure at the time of activation is acquired, and then it is determined whether the acquired air pressure is within the set air pressure range. If it is, the activation function of the circuit board assembly 100 is normal; otherwise, the activation function of the circuit board assembly 100 is abnormal. If the circuit board assembly 100 still does not activate when the air pressure reaches the upper limit of the set air pressure range, the activation function of the circuit board assembly 100 is abnormal. Thus, through the setting of the pressure detection element 23, the device realizes the detection of the activation function of the circuit board assembly 100.

[0162] In some embodiments of this application, such as Figure 4 and Figure 5 As shown, the base plate 112 has an air injection hole 21 and an air vent 22. The air injection hole 21 is used to allow gas to enter the sealing cavity 19 to increase the air pressure in the sealing cavity 19. The air vent 22 is used to allow the air pressure in the sealing cavity 19 to be discharged to reduce the air pressure in the sealing cavity 19. The base plate 112 is provided with a pressure detection element 23, which is used to detect the air pressure in the sealing cavity 19.

[0163] The carrier plate 13 supports the circuit board assembly 100. A positioning structure 14 is also provided above the carrier plate 13. Therefore, the space above the carrier plate 13 is relatively large, and the carrier plate 13 is positioned at a lower height within the sealed cavity 19. In other words, the carrier plate 13 is closer to the base plate 112 in the direction of gravity. Therefore, the air injection port 21, the air vent 22, and the pressure detection element 23 are positioned on the base plate 112, making them closer to the circuit board assembly 100 positioned on the carrier plate 13. Thus, when the air pressure within the sealed cavity 19 is adjusted through the air injection port 21 and the air vent 22, the circuit board assembly 100 can sense the pressure change more promptly, thereby triggering a wake-up change in a timely manner. Furthermore, the pressure detection element 23 can detect pressure changes promptly and more accurately, thereby improving the reliability of the wake-up detection.

[0164] In some embodiments of this application, such as Figure 4 and Figure 7 As shown, the air pressure wake-up detection device also includes a connector docking module 4 disposed in the main body 11 of the box. The connector docking module 4 includes a connector fixing block 41 connected to the base plate 112 and a docking connector 42 connected to the connector fixing block 41. In the sealed state, the docking connector 42 is connected to the connector 20 of the circuit board assembly 100 supported on the support station.

[0165] For example, connector 42 is a male connector, and connector 20 of circuit board assembly 100 is a female connector.

[0166] Understandably, the mating connector 42 is electrically connected to a power source. In a sealed state, the mating connector 42 is aligned with the connector 20 of the circuit board assembly 100 mounted on the support station, allowing the mating connector 42 to conduct current to the connector 20 of the circuit board assembly 100, thereby powering the circuit board assembly 100 and enabling it to be woken up, ensuring the smooth execution of the wake-up detection of the circuit board assembly 100.

[0167] For example, the mating connector 42 is oriented towards the carrier plate 13 and the sealing cover 12 along the first direction X. As the carrier plate 13 carries the circuit board assembly 100 and moves along the first direction X towards the box body 11, the connector 20 of the circuit board assembly 100 gradually approaches the mating connector 42. When the sealing cover 12 moves to the first opening 111 of the cover, it moves into place. At this time, the connector 20 is connected to the mating connector 42.

[0168] In some embodiments of this application, such as Figure 4 and Figure 7 As shown, the inner wall of the base plate 112 is provided with a mounting base 5, and the connector fixing block 41 is installed on the mounting base 5. The position of the connector fixing block 41 relative to the mounting base 5 along the first direction X is adjustable to adjust the position of the mating connector 42 along the first direction X.

[0169] The mounting base 5 enables the connector fixing block 41 to be fixed on the base plate 112. The position of the connector fixing block 41 relative to the mounting base 5 along the first direction X is adjustable, allowing for flexible and precise adjustment of the position of the mating connector 42. This improves the accuracy of mating between the mating connector 42 and the connector 20 of the circuit board assembly 100. Furthermore, by adjusting the connector fixing block 41 along the first direction X, it can be used to mate with circuit board assemblies 100 of different dimensions along the first direction X, increasing the flexibility of the device and expanding its applicability.

[0170] In some embodiments of this application, such as Figure 4 and Figure 7 As shown, the mounting base 5 has second connecting holes 51 that are spaced apart sequentially along the first direction X. The connector fixing block 41 has a third connecting hole 411. The third connecting hole 411 is connected to the second connecting hole 51 by a second fastener. By changing the second connecting hole 51 connected to the third connecting hole 411, the position of the mating connector 42 along the first direction X can be adjusted.

[0171] For example, the second fastener includes, but is not limited to, screws, bolts, nuts, rivets, etc.

[0172] Thus, by changing the second connecting hole 51 connected to the third connecting hole 411, the position of the mating connector 42 along the first direction X can be easily adjusted, thereby improving the mating accuracy between the mating connector 42 and the connector 20 of the circuit board assembly 100, and making it suitable for mating circuit board assemblies 100 with different dimensions along the first direction X. This increases the flexibility of the device and expands its application range. Furthermore, this connection structure is simple to operate; the position of the mating connector 42 can be quickly adjusted by selecting different second connecting holes 51 without complex positioning or calibration operations, thus saving connection time and labor costs. In addition, this connection method facilitates the overall assembly and disassembly of the connector mating module 4, allowing for the replacement of different models of the connector mating module 4 to mate with different models of circuit board assemblies 100, further expanding the applicability of the device.

[0173] In some embodiments of this application, such as Figure 7 As shown, the third connecting hole 411 is a strip-shaped hole extending along the first direction X.

[0174] If the position of the second fastener relative to the strip hole along the first direction X can be adjusted, the position of the mating connector 42 along the first direction X can be finely adjusted, thereby improving the accuracy of the position adjustment of the mating connector 42 and further improving the mating accuracy between the mating connector 42 and the connector 20 of the circuit board assembly 100.

[0175] In some embodiments of this application, the third connecting hole 411 is a circular hole.

[0176] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the air pressure wake-up detection device also includes a barcode scanning mechanism 6, which includes a barcode scanner 61. The barcode scanner 61 is used to scan the identification code of the circuit board assembly 100 carried on the bearing station.

[0177] Understandably, the outer surface of the circuit board assembly 100 has an identification code, such as a barcode or QR code containing relevant information about the circuit board assembly 100 (e.g., model, batch number, etc.). The barcode scanner 61 can obtain relevant information about the circuit board assembly 100 by scanning the identification code of the circuit board assembly 100.

[0178] By scanning the identification code on the circuit board assembly 100 using the barcode scanner 61 of the scanning mechanism 6, relevant information about the circuit board assembly 100 can be quickly obtained. This step greatly improves detection efficiency, reduces the error rate of manual input, and thus ensures the accuracy of subsequent detection steps.

[0179] In some embodiments of this application, such as Figure 3 and Figure 5As shown, the main body 11 of the box includes a bottom plate 112 and a top plate 113 arranged opposite each other along the third direction Z. The third direction Z intersects with the first direction X. The bottom plate 112 is located below the top plate 113. The scanning mechanism 6 also includes a third driving member 62, which is located on the side of the top plate 113 facing away from the bottom plate 112. The barcode scanner 61 is connected to the output end of the third driving member 62 and can reciprocate between the extended position and the retracted position along the first direction X under the action of the third driving member 62. In the retracted position, the projection of the barcode scanner 61 along the third direction Z falls entirely within the projection range of the top plate 113. In the extended position, the barcode scanner 61 extends beyond the edge of the top plate 113 along the first direction X, and in the open state, the scanning range of the barcode scanner 61 fully covers the identification code.

[0180] When in the retracted position, the projection of the barcode scanner 61's lens along the third direction Z falls entirely within the projection range of the top plate 113. That is, the lens of the barcode scanner 61 is directly above the top plate 113. In this position, the barcode scanner 61 occupies relatively little space along the first direction X, reducing space usage and facilitating storage and relocation of the device. When scanning is required, the barcode scanner 61, under the action of the third drive member 62, moves along the first direction X towards one side of the sealing cover 12 until it reaches the extended position. At this point, the lens of the barcode scanner 61 extends beyond the edge of the top plate 113 along the first direction X, allowing the scanning range of the barcode scanner 61 to fully cover the identification code. This enables the barcode scanner 61 to scan the identification code of the circuit board assembly 100, thereby obtaining relevant information about the circuit board assembly 100.

[0181] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the third drive unit 62 is mounted on the top plate 113 via the mounting assembly 63, and the position of the third drive unit 62 relative to the top plate 113 along the first direction X is adjustable.

[0182] It is understandable that the adjustable position of the third drive member 62 relative to the top plate 113 along the first direction X means that the entire structure of the third drive member 62 can move relative to the top plate 113 along the first direction X.

[0183] By installing component 63, the position of the third drive component 62 relative to the top plate 113 along the first direction X can be adjusted. With a fixed drive stroke of the third drive component 62, by adjusting the position of the third drive component 62, the extension and retraction positions of the barcode scanner 61 can be changed, thus making it suitable for scanning identification codes at different locations, and further suitable for scanning circuit board assemblies 100 of different sizes, expanding the scope of application.

[0184] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the mounting assembly 63 includes a mounting rail 631, a connecting slider 632, and a locking member 633. The mounting rail 631 extends along the first direction X and is fixed to the top plate 113. The connecting slider 632 has a sliding hole and slides onto the mounting rail 631 through the sliding hole. The third driving member 62 is mounted on the connecting slider 632 and can move with the connecting slider 632. The locking member 633 is connected to the connecting slider 632 and can lock the connecting slider 632 onto the mounting rail 631.

[0185] When the position of the third drive component 62 needs to be adjusted, first unlock the locking component 633. At this time, the connecting slider 632 can move along the mounting guide rail 631 with the third drive component 62. After moving to the appropriate position, lock the locking component 633. At this time, the connecting slider 632 is locked on the mounting guide rail 631, and the position of the connecting slider 632 is fixed. That is, the position of the third drive component 62 is fixed, and the position adjustment operation of the third drive component 62 is completed.

[0186] In this way, the position adjustment of the third drive component 62 is achieved, expanding the applicability of the device. Furthermore, the mounting assembly 63 used for adjusting and installing the third drive component 62 has a simple structure, is easy to adjust, and saves material and time costs.

[0187] In some embodiments of this application, such as Figure 2 As shown, the locking member 633 includes a threaded post 6331 and a handle 6332 connected to one end of the threaded post 6331. The connecting slider 632 is formed with a threaded hole communicating with the sliding hole. The end of the threaded post 6331 away from the handle 6332 is threadedly connected to the threaded hole and can be pressed against the mounting guide rail 631 when the handle 6332 is rotated.

[0188] By rotating the handle 6332, the threaded post 6331 is driven to rotate helically within the threaded hole, thereby causing the end of the threaded post 6331 away from the handle 6332 to press against or release the mounting guide rail 631. When the threaded post 6331 is released from the mounting guide rail 631, there is a gap between the threaded post 6331 and the mounting guide rail 631, and the connecting slider 632 can be easily pushed, thereby allowing the position of the connecting slider 632 and the third driving member 62 to be adjusted along the mounting guide rail 631; when the threaded post 6331 presses against the mounting guide rail 631, the position of the connecting slider 632 on the mounting guide rail 631 is locked, that is, the position of the third driving member 62 is fixed.

[0189] In this way, the locking component 633 locks the connecting slider 632 and the mounting rail 631. Moreover, the locking component 633 has a simple structure, and the locking and unlocking operations are simple and convenient.

[0190] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the main body 11 of the box includes two first side plates 114 facing each other along a first direction X, two second side plates 115 facing each other along a second direction Y, and a bottom plate 112 and a top plate 113 facing each other along a third direction Z. The two second side plates 115 are connected between the two first side plates 114, and the two first side plates 114 and the two second side plates 115 are connected between the bottom plate 112 and the top plate 113. One of the two first side plates 114 forms a first opening 111. When the sealing cover 12 is sealed to the first opening 111, the two first side plates 114, the two second side plates 115, the bottom plate 112, the top plate 113 and the sealing cover 12 form a sealed cavity 19.

[0191] For example, the bottom plate 112 of the box body 11 is fixedly connected to the first plate 31 of the base 3.

[0192] For example, part of the first plate 31 of the base 3 serves as the bottom plate 112 of the box body 11, and another part of the first plate 31 forms a sliding groove 161, which slides in conjunction with the sliding block 162 provided on the sealing cover 12.

[0193] The following describes specific examples of some embodiments of this application with reference to the accompanying drawings.

[0194] As a specific example, a pneumatic wake-up detection device is provided. The detection box 1 includes a box body 11 and a sealing cover 12. The box body 11 has a first opening 111 on one side along the first direction X. The sealing cover 12 is closable and seals the first opening 111, forming a sealed cavity 19 with the box body 11. The sealed cavity 19 is a sealed environment and is used to accommodate the circuit board assembly 100. An air injection hole 21, an air exhaust hole 22 and a pneumatic pressure detection hole are provided on the cavity wall of the sealed cavity 19. A pressure detection element 23 is provided in the pneumatic pressure detection hole.

[0195] During testing, the circuit board assembly 100 is placed inside the sealed cavity 19. The circuit board assembly 100 is first put into a dormant state, and then air is injected into the sealed cavity 19 through the air injection port 21 to increase the air pressure. If the circuit board assembly 100 is awakened during the pressure increase, the air pressure in the sealed cavity 19 is obtained through the pressure detection element 23. It is then determined whether the air pressure is within the set pressure range. If it is, the wake-up function of the circuit board assembly 100 is normal; otherwise, the wake-up function is abnormal. If the circuit board assembly 100 still does not wake up when the air pressure in the sealed cavity 19 increases to the upper limit of the set pressure range, the wake-up function of the circuit board assembly 100 is abnormal. After determining whether the wake-up function of the circuit board assembly 100 is normal or abnormal, the air injection operation is stopped. Then, air is vented outwards through the exhaust port 22 to ensure that the air pressure in the sealed cavity 19 is at a safe pressure, ensuring the air pressure accuracy of the sealed cavity 19 and personnel safety.

[0196] After the air pressure wake-up detection device completes the detection, abnormal circuit board assemblies 100 can be intercepted, reducing the probability of abnormal circuit board assemblies 100 flowing to the next process, thereby improving the shipment quality of BMS finished products.

[0197] The above embodiments are merely illustrative of the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application, and all should be covered within the scope of the specification of this application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way.
