Description

Technical Field

[0001] This application relates to the field of battery technology, specifically to a battery contour detection device and a battery production line. Background Technology

[0002] Currently, new energy vehicles are becoming increasingly popular due to their environmental friendliness. New energy vehicles utilize batteries to provide electrical energy to electric motors, which then drive the vehicle. In related technologies, a battery may include a housing, a cover, and individual battery cells. The housing and cover are fastened together to form a storage space, and the individual battery cells can be housed within this space.

[0003] During battery manufacturing, the contour of the top cover needs to be inspected to ensure that its performance meets design requirements. However, current inspection devices employ a cumbersome design, resulting in a bulky overall structure and complex operation, which cannot quickly inspect the contour to meet the cycle time requirements of rapid testing. Utility Model Content

[0004] In view of the above problems, this application provides a battery contour detection device and a battery production line, which can solve or alleviate the problem that the battery contour cannot be detected quickly to meet the cycle requirements of rapid detection.

[0005] In a first aspect, this application provides a battery contour detection device, the detection device comprising:

[0006] A frame, the frame including a cavity for mounting the battery;

[0007] Testing institutions, including:

[0008] A load assembly is movably mounted on the frame, the load assembly including a load wheel, the load assembly being configured such that the load wheel abuts against the battery of the battery, and is movable on the battery in a first direction;

[0009] A detection component is movably disposed on the frame, the detection component being configured to move along the first direction on the battery to detect the battery's contour.

[0010] In the aforementioned testing device, the load wheel can move on the battery along a first direction and come into contact with the battery, and the testing component can move along the same direction as the load wheel and detect the outline of the battery. Thus, the outline of the battery can be quickly detected by the movement of the load wheel and the testing component to meet the production cycle requirements.

[0011] In some embodiments, the load wheel is configured to abut against the battery under the influence of gravity.

[0012] In the above embodiments, the load wheel can abut against the battery under the action of gravity, making the load wheel adaptive. That is, the load wheel can rise and fall along the height direction according to the unevenness of the battery surface, thereby maintaining contact with the battery (pressing the battery), ensuring consistent load under dynamic detection conditions, and thus improving the detection accuracy of battery contour. Moreover, using gravity to keep the load wheel in contact with the battery can reduce the need to use other components (such as elastic elements) to apply the force to abut against the battery, thereby simplifying the structure of the detection device and reducing costs.

[0013] In some embodiments, the detection device includes a first beam, a load wheel with a connector that is vertically and flexibly passing through the first beam, the load wheel being connected to the first beam via the connector, and the load wheel being configured to lower the connector relative to the first beam under gravity and to raise the connector relative to the first beam under the upward pressure of the battery.

[0014] In the above embodiments, the first beam can effectively support the load wheel through the connecting member, allowing the load wheel to adaptively rise and fall. Specifically, when the load wheel abuts against the protruding part of the battery, the protruding part can apply an upward force to the load wheel, causing it to move upward, thereby driving the connecting member to rise relative to the first beam, while the load wheel remains in contact with the battery. When the load wheel abuts against the recessed part of the battery, the load wheel can, under the action of gravity, drive the connecting member to fall relative to the first beam, while the load wheel remains in contact with the battery.

[0015] In some embodiments, the load assembly includes an axle through which the load wheel passes, and a connector is connected to each end of the axle. The axial direction of the axle is perpendicular to the first direction.

[0016] In the above embodiments, a connector is connected to each end of the axle, which prevents the axle from tilting and causing the load wheel to separate from the battery during movement. This allows the load wheel to move more stably on the battery and also ensures the accuracy of battery contour detection to a certain extent.

[0017] In some embodiments, the load assembly includes a first array of load wheels and a second array of load wheels arranged at intervals along the first direction. Both the first array of load wheels and the second array of load wheels include a plurality of the load wheels. The plurality of load wheels are arranged at intervals along a second direction, and the first direction and the second direction are perpendicular to each other.

[0018] In the above embodiments, the first array load wheels and the second array load wheels are arranged at intervals along the first direction, and the multiple load wheels of each array load wheel are arranged at intervals along the second direction. Thus, load wheels can be arranged in both the first and second directions, decomposing the constraint force into load gravity, thereby simulating the constraint scenario of battery assembly, such as the constraint scenario of battery cover and vehicle body floor assembly.

[0019] In some embodiments, the detection component is disposed between the first array load wheel and the second array load wheel.

[0020] In the above embodiment, the detection component is located between the first array load wheel and the second array load wheel, so that the detection component can be closer to the two parts of the load wheel that abut against the battery. This can reduce the impact on the detection results caused by excessive contour changes due to excessive distance between the two parts of the detection component and the battery.

[0021] In some embodiments, the detection device includes a second beam, the detection assembly includes a detection element movably disposed on the second beam along a second direction, the detection element being configured to abut against the battery to detect the outline of the battery, the first direction being perpendicular to the second direction.

[0022] In the above embodiments, the detection element is movably disposed on the second beam along the second direction, so that the position of the detection element can be adjusted steplessly in the second direction, thereby allowing arbitrary adjustment of the part of the battery being detected.

[0023] In some embodiments, the detection assembly includes a plurality of the detection elements, which are arranged on the second beam along the second direction.

[0024] In the above embodiment, multiple detection components are arranged on the second beam along the second direction. Thus, when the load component and the detection component move along the first direction, a large area of ​​the battery contour can be detected in both the first and second directions, thereby improving the detection efficiency to a certain extent.

[0025] In some embodiments, the detection element includes a detection body and a roller, the detection body being movably disposed on the second beam, the roller being connected to the bottom of the detection body, and the detection element being configured to adaptively adjust its height via the roller in the height direction of the detection device.

[0026] In the above embodiments, the detection element is configured to adaptively adjust its height in the height direction of the detection device via rollers, so that the detection element can remain in contact with the battery (pressing the battery), ensuring consistent load under dynamic detection conditions, thereby improving the detection accuracy of battery contour.

[0027] In some embodiments, the detection component includes a detection element and a prompting element, the detection element and the prompting element being electrically connected, the detection element being configured to abut against the battery to detect contour, and the prompting element being configured to issue a non-compliance prompt if the contour of the battery exceeds a set range, and / or issue a compliance prompt if the contour of the battery does not exceed the set range.

[0028] In the above embodiments, the prompting device is configured to issue a non-compliance prompt when the battery's profile exceeds a set range, and / or issue a compliance prompt when the battery's profile does not exceed the set range. Therefore, inspectors can collect inspection information in real time through the prompting device to quickly determine the non-compliance and / or compliance points of the battery.

[0029] In some embodiments, the detection element includes a screen configured to display the outline of the battery.

[0030] In the above embodiments, the screen is configured to display the outline of the battery, allowing inspectors to quickly understand the outline of each inspection point on the battery.

[0031] In some embodiments, the frame is provided with a first positioning part, which is configured to cooperate with and connect with a second positioning part on the battery to position the detection device on the battery.

[0032] In the above embodiments, the cooperation and connection between the first positioning part and the second positioning part improves the assembly efficiency of the detection device and the battery to a certain extent.

[0033] In some embodiments, the first positioning part includes at least one of a first positioning hole, a first positioning pin, and a first positioning surface, and the second positioning part includes at least one of a second positioning pin, a second positioning hole, and a second positioning surface. The first positioning pin is configured to cooperate with the second positioning hole, the first positioning hole is configured to cooperate with the second positioning pin, and the first positioning surface is configured to cooperate with the second positioning surface.

[0034] In the above embodiments, the detection device and the battery can be assembled together through the mutual cooperation of the positioning hole and the positioning pin, and the mutual cooperation of the positioning surface. The structure is simple and easy to implement.

[0035] In some embodiments, the detection device includes a bracket, a slide rail, and a slide groove. The slide rail is connected to each other. One of the slide rail and the slide groove is disposed on the frame, and the other is disposed on the bracket. The detection component and the load component are disposed on the bracket. The bracket is configured to drive the load component and the detection component to move synchronously along the first direction.

[0036] In the above embodiments, the slide rails are connected to each other, thereby guiding the synchronous movement of the load component and the detection component, and improving the movement stability of the detection component and the load component to a certain extent.

[0037] Secondly, this application provides a battery production line, which includes the testing device of any of the above embodiments.

[0038] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

[0063] Unless otherwise specified, all technical features and optional technical features of this application may be combined to form new technical solutions.

[0064] Currently, new energy vehicles are becoming increasingly popular due to their environmental friendliness. New energy vehicles utilize batteries to provide electrical energy to electric motors, which then drive the vehicle. In related technologies, a battery may include a housing, a cover, and individual battery cells. The housing and cover are fastened together to form a storage space, and the individual battery cells can be housed within this space.

[0065] During battery manufacturing, the contour of the top cover needs to be inspected to ensure that its performance meets design requirements. However, current inspection devices employ a cumbersome design, resulting in a bulky overall structure and complex operation, which cannot quickly inspect the contour to meet the cycle time requirements of rapid testing.

[0066] To address or alleviate the problem that battery contour cannot be detected quickly enough to meet the time-of-flight requirements of rapid detection, this application provides a battery contour detection device, the detection device comprising:

[0067] A frame, the frame including a cavity for mounting a battery;

[0068] Testing institutions, including:

[0069] A load assembly is movably mounted on the frame, the load assembly including a load wheel, the load assembly being configured such that the load wheel abuts against the battery of the battery, and is movable on the battery in a first direction;

[0070] A detection component is movably disposed on the frame, the detection component being configured to move along the first direction on the battery to detect the battery's contour.

[0071] In the technical solution of this application embodiment, the load wheel can move on the battery along a first direction and abut against the battery, and the detection component can move along the same direction as the load wheel and detect the outline of the battery. Thus, the outline of the battery can be quickly detected by the movement of the load wheel and the detection component to meet the production cycle requirements.

[0072] Profile tolerance is used to measure the degree of deviation between the actual profile and the ideal profile, controlling the shape accuracy of a surface or line. A satisfactory profile tolerance requires that every point on the actual surface must lie within the tolerance zone, which is the area between two equidistant surfaces, spaced at a distance of tolerance value t, and symmetrically distributed relative to the ideal surface (determined by design data).

[0073] Firstly, according to some embodiments of this application, please refer to Figures 1 to 10This application provides a contour detection device 100 for a battery 300. The detection device 100 includes a frame 10 and a detection mechanism 12. The frame 10 includes a cavity 13 for mounting the battery 300. The detection mechanism 12 includes a load assembly 20 and a detection assembly 30. The load assembly 20 is movably mounted on the frame 10 and includes a load wheel 21. The load assembly 20 is configured such that the load wheel 21 abuts against the battery 300 and is movable on the battery 300 along a first direction.

[0074] The detection component 30 is movably disposed on the frame 10 and is configured to move along a first direction on the battery 300 to detect the contour of the battery 300.

[0075] Optionally, in one embodiment, in Figure 1 , Figure 8 and Figure 9 In this design, battery 300 can be a battery assembly, comprising an upper housing 301 and a lower housing 302, which can be fastened together to form a space for accommodating individual battery cells. After the upper housing 301 and lower housing 302 of battery 300 are assembled, the contour of the upper housing 301 needs to be checked to ensure that it meets design requirements. Individual battery cells may include, but are not limited to, cylindrical battery cells, prismatic battery cells, pouch-shaped battery cells, and blade-shaped battery cells.

[0076] The frame 10 is used to connect to the battery 300. Specifically, the frame 10 includes a cavity 13, which can accommodate the battery 300, allowing the detection mechanism 12 to act on the upper housing 301 of the battery 300. The frame 10 can serve as a support frame for the detection device 100 to be mounted and positioned on the upper housing. By placing the frame 10 in a preset position on the battery 300, the load assembly 20 and the detection assembly 30 can be placed on the surface of the upper housing 301. Optionally, during the detection process, the frame 10 can be fixed in place, while the load assembly 20 and the detection assembly 30 can move relative to the frame 10 along a first direction to detect the contour of the upper housing 301.

[0077] Optionally, in one embodiment, the battery 300 may be a battery module, which is formed by arranging and fixing multiple battery cells into an independent module. As an example, the battery module can be formed by binding multiple battery cells together with cable ties and end plates. The battery module may be a component for which contour detection is required. Specifically, the upper surface of the end plate can serve as a positioning surface, and the frame 10 can be disposed on the upper surface of the end plate. Optionally, when the height of the upper surface of the end plate is lower than the height of the upper surface of the battery cell, a shim can be provided on the upper surface of the end plate so that the height of the upper surface of the shim meets the detection conditions with the height of the upper surface of the battery cell. The frame 10 is assembled onto the battery module through the cavity 13 for contour detection.

[0078] This application does not specifically limit the shape and material of the frame 10. Optionally, in one embodiment, the frame 10 may be made of a single piece of high-strength aluminum alloy. Handles 11 are provided on both sides of the frame 10, allowing inspection personnel or equipment to move the inspection device 100 via the handles 11. The frame 10 may have a main positioning surface machined on it for positioning and installation with the battery 300.

[0079] The main function of the testing mechanism 12 is to realize the assembly constraint scenario of the battery 300 with the vehicle chassis or other components, and to detect the contour of the battery 300 in the final scenario. For ease of explanation and understanding, the following uses the battery as a battery device as an example to describe the embodiments of this application.

[0080] Specifically, the load assembly 20 is used to simulate constraints acting on the upper housing 301, thereby simulating the assembly constraint scenario of the upper housing 301 and other components in the form of dynamic load. For example, simulating the assembly constraint scenario of the battery 300 and the vehicle chassis. Specifically, the load assembly 20 includes a load wheel 21, which can abut against the upper housing 301, so that the load wheel 21 can apply a certain constraint force to the upper housing 301 to simulate the assembly constraint of the upper housing 301. The load assembly 20 is movably mounted on the frame 10. During testing, the load assembly 20 can move from one side to the other along the first direction on the surface of the upper housing 301, achieving 100% detection of the contour of the surface of the upper housing 301. Figure 1 and Figure 2 In the illustrated embodiment, the first direction includes directions A1 and A2. The load assembly 20 can move from the rear to the front of the top surface of the upper housing 301, achieving 100% contour detection of the top surface of the upper housing 301. The load assembly 20 can be driven by an electric drive or manually to move relative to the frame 10 on the upper housing 301. Optionally, in one embodiment, the load wheel 21 can roll. The rolling load wheel 21 can reduce the movement resistance of the load assembly 20. In addition, the load assembly 20 can be used to simulate constraints acting on the upper housing 301, thereby simulating the assembly constraint scenario of the upper housing 301 and other components in the form of dynamic load, which is beneficial to improving detection efficiency. It is understood that the movement of the load wheel 21 is not limited to rolling, but can also be sliding.

[0081] The detection component 30 can detect the contour of the upper housing 301 of the battery 300 under simulated constraint scenarios. Specifically, the detection component 30 is movably mounted on the frame 10 and can move along the upper housing 301 in a first direction. The detection component 30 and the load component 20 can move synchronously or asynchronously. Optionally, in one embodiment, the detection component 30 includes a detection element 31 configured to abut against the upper housing 301 to detect the contour of the upper housing 301. Optionally, the detection element 31 includes a roller 32, and the detection element 31 abuts against the surface of the upper housing 301 via the roller 32. When the detection component 30 moves, on the one hand, the detection element 31 can move on the surface of the upper housing 301 via the roller 32, thereby reducing the moving resistance of the detection component 30; on the other hand, the detection element 31 can abut against the surface of the upper housing 301 via the roller 32, and the contour of the upper housing 301 can be detected during the movement.

[0082] It is understandable that the distance between the first abutting position of the detection element 31 on the upper housing 301 and the second abutting position of the load wheel 21 on the upper housing 301 is based on the ability of the detection element 31 to detect the contour of the part of the upper housing 301 abutted by the load wheel 21.

[0083] In the aforementioned detection device 100, the load wheel 21 can move along the first direction on the battery 300 and abut against the battery 300, and the detection component 30 can move along the same direction as the load wheel 21 and detect the profile of the battery 300. Thus, the profile of the battery 300 can be quickly detected by the movement of the load wheel 21 and the detection component 30 to meet the production cycle requirements.

[0084] According to some embodiments of this application, optionally, please refer to... Figures 3 to 6 The load wheel 21 is configured to abut against the battery 300 under the action of gravity.

[0085] Specifically, the load wheel 21 can abut against the battery 300 under the action of gravity, making the load wheel 21 adaptive. That is, the load wheel 21 can rise and fall along the height direction according to the unevenness of the surface of the battery 300, thereby maintaining contact with the battery 300 (pressing the battery 300), ensuring consistent load under dynamic detection conditions, and thus improving the detection accuracy of the battery 300 contour. Moreover, by using gravity to keep the load wheel 21 in contact with the battery 300, the need for other components (such as elastic elements) to apply the force to abut against the battery 300 can be reduced, thereby simplifying the structure of the detection device 100 and reducing costs.

[0086] Optionally, in one embodiment, foam 303 is provided on certain areas of the surface of the upper housing 301. The foam 303 is provided because the battery 300 needs to be tightly fitted in certain positions when installed in the vehicle, and foam 303 can be provided at the corresponding positions to achieve soft contact. Therefore, based on specific product requirements, foam 303 is also designed at the corresponding positions during product morphology inspection. The foam 303 protrudes from the surface of the upper housing 301. When the load wheel 21 moves to the stepped area of ​​the foam 303, in one embodiment, since the load wheel 21 adopts a roller structure, it achieves a certain height of passability, ensuring smooth movement in the measurement direction and consistency of load weight, ultimately realizing rapid measurement and identification of NG points, and realizing online 100% battery 300 simulated whole vehicle constraint scenario inspection.

[0087] The magnitude of the gravity exerted by the load wheel 21 on the upper housing 301 can be determined based on the constraint force under the assembly constraint scenario of the upper housing 301, and this application does not make specific limitations on this.

[0088] According to some embodiments of this application, optionally, please refer to... Figures 2 to 4 The detection device 100 includes a first beam 40, a load wheel 21 with a connecting member 22, the connecting member 22 being vertically and vertically inserted through the first beam 40, the load wheel 21 being connected to the first beam 40 through the connecting member 22, the load wheel 21 being configured to drive the connecting member 22 to descend relative to the first beam 40 under the action of gravity and to drive the connecting member 22 to rise relative to the first beam 40 under the upward pressure of the battery 300.

[0089] The first beam 40 can effectively support the load wheel 21 through the connector 22, allowing the load wheel 21 to adaptively rise and fall. Specifically, when the load wheel 21 abuts against the protruding part of the battery 300, the protruding part can apply an upward force to the load wheel 21, causing the load wheel 21 to move upward, thereby driving the connector 22 to rise relative to the first beam 40, while the load wheel 21 remains in contact with the battery 300. When the load wheel 21 abuts against the recessed part of the battery 300, the load wheel 21 can, under the action of gravity, drive the connector 22 to fall relative to the first beam 40, while the load wheel 21 remains in contact with the battery 300.

[0090] Optionally, in one embodiment, the connector 22 includes a T-shaped portion 221 and a connecting portion 222. The T-shaped portion 221 includes a shaft and a flange, with the flange located at one end of the shaft and the connecting portion 222 located at the other end of the shaft. The shaft passes through the first beam 40, and the flange can limit the maximum descent distance of the load wheel 21. The connecting portion 222 is rotatably connected to the load wheel 21, allowing the load wheel 21 to roll as it moves in the first direction, thereby reducing the moving resistance of the load assembly 20 and improving detection efficiency. Optionally, in one embodiment, the load assembly has an external soft sleeve (such as a soft knurled sleeve), which helps protect the upper housing 301.

[0091] According to some embodiments of this application, optionally, please refer to... Figure 4 and Figure 10 The load assembly 20 includes an axle 23 through which a load wheel 21 passes. A connector 22 is connected to each end of the axle 23. The axial direction of the axle 23 is perpendicular to the first direction.

[0092] A connector 22 is connected to each end of the axle 23, which prevents the load wheel 21 from tilting during movement and causing it to separate from the battery 300. This allows the load wheel 21 to move more stably on the battery 300 and also ensures the accuracy of the battery 300 contour detection to a certain extent.

[0093] The axial direction of the axle 23 is perpendicular to the first direction, which allows the load wheel 21 to roll when it moves along the first direction, thereby reducing the resistance to movement.

[0094] Optionally, in Figure 6 In the process, the connecting member 22 includes a T-shaped portion 221 and a connecting portion 222. The T-shaped portion 221 includes a shaft and a flange. The flange is located at one end of the shaft, and the connecting portion 222 is located at the other end of the shaft. The shaft passes through the first beam 40, and the flange can limit the maximum descent distance of the load wheel 21. A connecting portion 222 is connected to each end of the wheel axle 23.

[0095] According to some embodiments of this application, optionally, please refer to... Figure 1 and Figure 2 The load assembly 20 includes a first array load wheel 24 and a second array load wheel 25 arranged at intervals along a first direction. Both the first array load wheel 24 and the second array load wheel 25 include a plurality of load wheels 21. The plurality of load wheels 21 are arranged at intervals along a second direction, and the first direction and the second direction are perpendicular to each other.

[0096] The first array load wheel 24 and the second array load wheel 25 are arranged at intervals along the first direction, and multiple load wheels 21 of each array load wheel 21 are arranged at intervals along the second direction. Thus, load wheels 21 can be arranged in both the first and second directions, decomposing the constraint force into load gravity, thereby simulating the constraint scenario of battery 300 assembly, such as the constraint scenario of battery 300 being assembled with the vehicle body floor.

[0097] Optionally, the first direction includes Figure 1 The directions A1 and A2 are shown, and the second direction includes... Figure 1 As shown in directions A3 and A4, the third direction includes... Figure 1 In directions A4 and A5, the third direction is perpendicular to both the second and first directions. Optionally, direction A5 is the direction of gravity, and direction A4 is the direction opposite to gravity. Load wheels 21 are arranged in directions A1, A2, A3, and A4, which decomposes the constraint force into load gravity in directions A1, A2, A3, and A4 (e.g., front-back, left-right), thus improving the accuracy of contour detection.

[0098] According to some embodiments of this application, optionally, please refer to... Figure 1 and Figure 2 The detection component 30 is located between the first array load wheel 24 and the second array load wheel 25.

[0099] The detection component 30 is located between the first array load wheel 24 and the second array load wheel 25, so that the detection component 30 can be closer to the two parts of the load wheel 21 of the two array load wheels 21 that abut against the battery 300. This can reduce the impact on the detection results caused by excessive changes in the contour due to excessive distance between the two parts of the detection component 30 and the battery 300.

[0100] Optionally, in one embodiment, the detection component 30 may be located at the middle position between the first array load wheel 24 and the second array load wheel 25, which can further improve the accuracy of the detection component 30 in detecting the contour.

[0101] According to some embodiments of this application, optionally, please refer to... Figures 1 to 2 The detection device 100 includes a second beam 50, and the detection assembly 30 includes a detection element 31. The detection element 31 is movably disposed on the second beam 50 along a second direction. The detection element 31 is configured to abut against the battery 300 to detect the outline of the battery 300. The first direction and the second direction are perpendicular to each other.

[0102] The detection element 31 is movably mounted on the second beam 50 along the second direction, allowing its position to be adjusted steplessly in the second direction, thereby enabling arbitrary adjustment of the detected part of the battery 300. Figure 1 and Figure 2 In the middle, the second direction includes directions A3 and A4, and the first direction includes directions A1 and A2. That is, the detection element 31 can be movably disposed on the second beam 50 along directions A3 and A4, and can be moved on the battery 300 along directions A1 and A2.

[0103] Optionally, the first beam 40 and the second beam 50 are parallel to each other, and their length directions are parallel to the second direction. This can form a more regular structure, which is beneficial to maintaining the compactness of the detection device 100.

[0104] According to some embodiments of this application, optionally, please refer to... Figure 1 , Figure 2 and Figure 8 The detection assembly 30 includes a plurality of detection elements 31, which are arranged on the second beam 50 along the second direction.

[0105] Multiple detection components 31 are arranged on the second beam 50 along the second direction. Thus, when the load assembly 20 and the detection assembly 30 move along the first direction, a large area of ​​the battery 300 can be detected in the first and second directions, thereby improving the detection efficiency to a certain extent.

[0106] Optionally, in one embodiment, the width occupied by the plurality of detection elements 31 arranged along the second direction is equivalent to the width of the upper housing 301. Thus, after the detection component 30 and the load component 20 move from one side (e.g., from the A2 side) to the other side (e.g., the A1 side) of the upper housing 301 along the first direction, the contour detection of the entire surface of the upper housing 301 can be completed, further improving the detection efficiency.

[0107] According to some embodiments of this application, optionally, please refer to... Figure 4 The detection element 31 includes a detection body 33 and a roller 32. The detection body 33 is movably mounted on the second beam 50, and the roller 32 is connected to the bottom of the detection body 33. The detection element 31 is configured to adaptively adjust its height in the height direction of the detection device 100 via the roller 32.

[0108] The detection element 31 is configured to adaptively adjust its height in the height direction of the detection device 100 via the roller 32, so that the detection element 31 can remain in contact with the battery 300 (pressing the battery 300), ensuring consistent load under dynamic detection conditions, thereby improving the detection accuracy of the battery 300 profile.

[0109] The detection body 33 is a component that detects the contour of the upper housing 301 by abutting against the upper housing 301 via rollers 32. Optionally, in one embodiment, the surface area of ​​the upper housing 301 will form a local sag area (simulating vehicle assembly constraints) under a fixed gravity load (gravity of the load wheel 21). In the sag area, the adaptive detection component 31 will measure the real-time contour of that point. Foam 303 is provided on certain areas of the surface of the upper housing 301. The area where the foam 303 is located is a protruding area on the surface of the upper housing 301. When the rollers 32 of the load wheel 21 and the detection component 31 move to the stepped area of ​​the foam 303, since both the load wheel 21 and the detection component 31 adopt a roller structure, a certain height of passability is achieved, ensuring smooth movement in the measurement direction and consistency of load weight. Ultimately, it can quickly measure and identify NG points, and realize online 100% battery 300 simulated vehicle constraint scenario detection.

[0110] According to some embodiments of this application, optionally, please refer to... Figures 1 to 4 The test piece 31 includes a roller dial indicator.

[0111] The roller dial indicator is a high-precision, high-sensitivity measuring tool widely used in manufacturing, machinery, and instrumentation. It consists of a case, probe, indicator, rack, roller 32, and measurement range selection device. The measuring body 33 also comprises a case, probe, indicator, rack, and measurement range selection device. The roller 32 is connected to the probe. The roller 32 rolls on the upper housing 301, converting changes in the upper housing 301's dimensions into pointer rotation. Specifically, the roller dial indicator works by amplifying the minute linear movement of the measuring rod caused by the dimensions of the upper housing 301 through gear transmission, transforming it into pointer rotation on the scale, thus reading the size of the upper housing 301's profile. During measurement, the roller 32 is pressed against the upper housing 301, and the linkage between the internal rack and roller 32 converts the profile of the upper housing 301 into a pointer reading.

[0112] The roller dial indicator is easy to use. It can provide direct readings or be used in conjunction with measuring instruments via external devices, making operation simple. The roller dial indicator also boasts high sensitivity; the roller 32 and rack-and-pinion linkage system of the roller dial indicator are highly sensitive and can quickly respond to changes in the dimensions of the upper housing 301.

[0113] According to some embodiments of this application, optionally, please refer to... Figure 1 , Figure 4 and Figure 8The detection component 30 includes a detection element 31 and a prompting element 34, which are electrically connected. The detection element 31 is configured to abut against the battery 300 to detect the profile. The prompting element 34 is configured to issue a failure prompt when the profile of the battery 300 exceeds a set range, and / or issue a pass prompt when the profile of the battery 300 does not exceed the set range.

[0114] Inspectors can pre-set tolerance ranges, which can be used as the set range. The inspection component 31 is used to detect the profile of the battery 300 in real time. If the detected profile exceeds the set range, the prompt component 34 issues a non-conforming warning, and / or if the detected profile does not exceed the set range, it issues a conforming warning.

[0115] Optionally, in one embodiment, the prompting element 34 includes a warning light. When the detected contour exceeds the set range, the warning light emits a red light to indicate that it is unqualified. When the detected contour does not exceed the set range, the warning light emits a green light to indicate that it is qualified.

[0116] The indicator 34 is configured to issue a failure warning when the profile of the battery 300 exceeds a set range, and / or issue a pass warning when the profile of the battery 300 does not exceed the set range. Thus, inspectors can collect inspection information in real time through the indicator 34 to quickly determine the points where the battery 300 is unqualified or / or qualified.

[0117] According to some embodiments of this application, optionally, please refer to... Figure 1 The detection element 31 includes a screen 311, which is configured to display the outline of the battery 300.

[0118] The screen 311 is configured to display the outline of the battery 300, allowing inspectors to quickly understand the outline of each inspection point on the battery 300.

[0119] During the movement of the load component 20 and the detection component 30, the screen 311 of the detection component 31 can display the contour value of the upper box 301 in real time, which makes it convenient for the inspection personnel to understand the inspection results while conducting the inspection, and helps the inspection personnel to quickly understand the inspection results.

[0132] According to some embodiments of this application, optionally, please refer to... Figure 1 and Figure 8 The detection device 100 includes a bracket 80, a slide rail 90, and a slide groove 91. The slide rails 90 are connected to each other. One of the slide rails 90 and the slide groove 91 is located on the frame 10, and the other is located on the bracket 80. The detection component 30 and the load component 20 are located on the bracket 80. The bracket 80 is configured to drive the load component 20 and the detection component 30 to move synchronously along a first direction.

[0133] The slide rails 90 are connected to each other, thereby guiding the synchronous movement of the load component 20 and the detection component 30, and improving the movement stability of the detection component 30 and the load component 20 to a certain extent.

[0134] Alternatively, in one embodiment, please combine Figure 1 and Figure 8 The slide rails 90 are mounted on the frame 10, specifically on the left and right sides of the frame 10. The sliding grooves 91 are mounted on the bracket 80, specifically on the left and right sides of the bracket 80. The detection component 30 and the load component 20 are both mounted on the bracket 80. When the bracket 80 moves, on the one hand, it can drive the load component 20 and the detection component 30 to move synchronously along the first direction, saving the time of separate movement and improving detection efficiency. On the other hand, the sliding grooves 91 and the slide rails 90 cooperate and connect, making the movement of the bracket 80, load component 20, and detection component 30 more stable under the guidance of the sliding grooves 91 and the slide rails 90 during the detection process, thus improving detection accuracy to a certain extent.

[0135] Optionally, in one embodiment, the bracket 80 includes two first beams 40 and a second beam 50, the two first beams 40 being respectively disposed on both sides of the second beam 50 along a first direction, an adaptive load wheel 21 being mounted on the first beam 40, and an adaptive detection element 31 being mounted on the second beam 50.

[0136] Optionally, in one embodiment, the slide rail 90 is disposed on the bracket 80, and the slide groove 91 is disposed on the frame 10.

[0137] Alternatively, in one embodiment, please combine Figure 1 , Figure 7 and Figure 8 The detection device 100 includes a push handle 92, which is mounted on a bracket 80. Inspection personnel or other equipment can easily operate the push handle 92 to move the bracket 80 along a first direction, causing the bracket 80 to drive the load assembly 20 and the detection assembly 30 to move synchronously along the first direction. This improves the ease of moving the bracket 80 and increases efficiency.

[0138] Optionally, in Figure 1 and Figure 8 In the bracket 80, a push handle 92 is provided on each of the left and right sides. Either push handle 92 or both push handles 92 can be operated by a testing personnel or other equipment to move the bracket 80, load assembly 20, and testing assembly 30 along a first direction. It is understood that this application does not specify the number of push handles 92.

[0139] Optionally, in one embodiment, the detection process of the detection device 100 of this application is described below.

[0140] The frame 10 can be assembled with the battery 300 through the positioning connection of the first positioning part 60 and the second positioning part 70. A bracket 80 is installed on the slide rail 90 on the frame 10. The bracket 80 has a three-in-one structure: a first array load wheel 24, a second array load wheel 25, and a detection component 30. The weight of the load wheel 21 is set according to the assembly constraint force between the battery 300 and the chassis. The second beam 50 is infinitely equipped with adaptive detection components 31 (such as roller dial indicators) and prompting components 34 (such as warning lights) according to the measurement point requirements of the upper housing 301 of the battery 300. Finally, it forms a detection device 100 for the contour of the entire upper housing 301. Before use, the detection device 100 needs to be zeroed on the standard parts of the battery 300. After zeroing, the detection judgment is set according to the detection tolerance. Through the connection and coupling of the detection component 31 and the prompting component 34, the real-time prompt information feedback of the detection is realized.

[0141] The calibrated testing device 100 is positioned onto the battery 300 via the first positioning part 60 and the second positioning part 70 (e.g., Figure 7 As shown), after positioning, the first array load wheel 24 and the second array load wheel 25 press against the top of the upper housing 301 of the battery 300 under the action of gravity. The upper housing 301 area will form a local sag area under the fixed gravity load (simulating the assembly constraints of the whole vehicle). In the sag area, the adaptive detection component 31 will measure the real-time contour value of the point. When the measured value is within the set range, the corresponding prompt component 34 will turn green. When the measurement exceeds the set range, it will turn red. The specific data can be read on the screen 311 of the detection component 31. The inspection personnel can collect the inspection information in real time through the information of the prompt component 34. The push handle 92 can be pushed synchronously at the same time. The load component 20 and the detection component 30 move in the length direction (first direction) of the upper housing 301. The contour data of the upper housing 301 in the moving direction will be measured and read in real time.

[0142] When passing through the stepped area of ​​the external foam 303 of the upper housing 301, the load wheel 21 and the detection piece 31 both adopt a roller structure, which achieves a certain height of passability, ensuring smooth movement in the measurement direction and consistency of load weight. Ultimately, it realizes rapid measurement and identification of NG points, and realizes online 100% simulated whole vehicle constraint scenario detection of the battery 300. The overall efficiency is improved by more than 80% compared with traditional offline inspection tools, and the contour measurement of the flexible deformation interface of the upper housing 301 of the battery 300 is realized, meeting the customer's real assembly needs.

[0143] Secondly, this application provides a battery production line, which includes the testing device 100 of any of the above embodiments.

[0144] Optionally, the testing device 100 can be located downstream of the battery production line, with a battery assembly line upstream. During battery assembly, individual battery cells can be assembled into the lower housing 302, and then the upper housing 301 and the lower housing 302 are fastened together to form a space for accommodating the individual battery cells. The assembled battery can be conveyed to the contour detection station via a conveyor belt, where the contour detection device is installed on the battery, and then the contour of the upper housing 301 can be detected.
