[0027] The battery detection device 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0028] like Figures 1 to 3 As shown, the battery testing device 100 according to an embodiment of the present invention includes: a frame 1 and a testing component 2. The testing component 2 is disposed on the frame 1 and includes a weighing platform 21 and an appearance inspection module 22. The weighing platform 21 is used to place and weigh the battery 200 to be tested. The appearance inspection module 22 is located above the weighing platform 21 and is used to acquire an appearance image of the battery 200 to be tested. That is, during the battery testing process, after the battery 200 to be tested is placed on the weighing platform 21, the weight of the battery 200 to be tested can be obtained through the weighing platform 21. At the same time, the appearance image of the battery 200 to be tested can be acquired through the appearance inspection module 22. That is, the battery testing device 100 can simultaneously acquire the weight and appearance image of the battery 200 to be tested. Among them, the state of the battery 200 to be tested can be judged from the weight by obtaining the weight, and the state of the battery 200 to be tested can be judged from the appearance by obtaining the appearance image, such as whether there are appearance defects such as bulges or cracks.

[0029] Therefore, by acquiring the weight and appearance image of the battery under test 200 through the weighing platform 21 and the appearance inspection module 22 respectively, it is easier to judge the state of the battery more comprehensively based on the weight and appearance image of the battery under test 200, thereby providing accurate data support for battery testing and improving the accuracy of battery testing device 100 in testing batteries.

[0030] For example, the battery testing device 100 can detect the difference between the battery before and after testing. Specifically, before testing, the battery testing device 100 can measure the weight of the battery before testing and obtain an image of its appearance, which is recorded as the weight before testing and the appearance before testing. After testing, the battery testing device 100 can again measure the weight of the battery after testing and obtain an image of its appearance, which is recorded as the weight after testing and the appearance after testing. The difference between the weight before and after testing can be used to determine the weight change of the battery before and after testing, and the difference between the appearance before and after testing can be used to determine the appearance change of the battery before and after testing. This provides accurate data support for battery quality inspection and improves the accuracy of battery testing.

[0031] According to the battery testing device 100 of this utility model embodiment, the weight and appearance image of the battery under test 200 are obtained by the weighing platform 21 and the appearance inspection module 22, respectively. This makes it easier to judge the state of the battery more comprehensively based on the weight and appearance image of the battery under test 200, thereby providing accurate data support for battery testing and improving the accuracy of battery testing by the battery testing device 100.

[0032] In some embodiments, such as Figure 3 As shown, the weighing platform 21 includes a placement plate 211 and a pressure sensor 212. The pressure sensor 212 is located at the bottom of the placement plate 211. The placement plate 211 is used to place the battery 200 to be tested. When the battery 200 to be tested is placed on the placement plate 211, pressing down on the placement plate 211 causes the pressure exerted by the placement plate on the pressure sensor 212 to increase. Thus, the weight of the battery 200 to be tested can be obtained based on the pressure change value of the pressure sensor 212.

[0033] According to some embodiments of this utility model, such as Figures 2-5 As shown, the detection component 2 also includes a drive unit 23 and a distance sensor 24. The distance sensor 24 is used to measure the distance between the appearance detection module 22 and the battery 200 under test. The drive unit 23 is connected to the appearance detection module 22 and is at least used to drive the appearance detection module 22 closer to or further away from the weighing platform 21. Since batteries of different specifications have different heights, such as... Figure 3The cylindrical and prismatic batteries shown have different heights. Therefore, when batteries of different specifications are placed on the weighing platform 21, the distance between the battery 200 and the appearance inspection module 22 also varies. Thus, after the battery 200 is placed on the weighing platform 21, the distance between the appearance inspection module 22 and the battery 200 is obtained through the distance sensor 24. This helps determine whether the battery 200 is at the optimal shooting distance of the appearance inspection module 22, where the optimal shooting distance refers to the distance between the appearance inspection module 22 and the battery 200 being the ideal focal length of the appearance inspection module 22.

[0034] When the distance between the appearance inspection module 22 and the battery under test 200 does not meet the ideal focal length, the drive unit 23 can drive the appearance inspection module 22 closer to or further away from the weighing platform 21 to adjust the distance between the appearance inspection module 22 and the battery under test 200. During this process, the distance between the appearance inspection module 22 and the battery under test 200 is detected in real time by the distance sensor 24 until the battery under test 200 placed on the weighing platform 21 is at the optimal shooting distance of the appearance inspection module 22, ensuring that the appearance inspection module 22 can obtain a clearer image of the appearance of the battery under test 200. Therefore, through the cooperation of the distance sensor 24 and the drive unit 23, the clarity of the appearance image of the battery under test 200 obtained by the appearance inspection module 22 can be improved, thereby improving the detection accuracy of the battery detection device 100.

[0035] According to some embodiments of this utility model, the appearance inspection module 22 is also used to scan the identification QR code on the battery under test 200. The identification QR code can record some parameter information of the battery under test 200, such as the serial number. Therefore, the serial number and other identification information of the battery under test 200 can be accurately determined through the information in the identification QR code. This facilitates subsequent archiving of the test data of the battery under test 200, such as weight and appearance images, based on the serial number and other identification information, thereby improving the accuracy of the battery testing device 100 in detecting the battery under test 200.

[0036] Specifically, the battery testing device 100 also includes a back-end processing system. When the operator places the battery 200 to be tested in front of the weighing platform 21, they can first scan the QR code on the battery 200 using the appearance inspection module 22. The back-end processing system reads the serial number of the battery 200 and automatically creates a folder named after that serial number in a specified path on the industrial computer. All subsequent photos of the battery 200 (including its appearance before testing and deformation after testing) are saved to this folder by default until the next battery 200's QR code is scanned, at which point the path is automatically switched. This effectively avoids folder confusion and slow archiving efficiency during photo archiving.

[0037] Furthermore, the weighing data from the weighing platform 21 is seamlessly integrated with the LIMS (Laboratory Information Management System). After the weighing platform 21 acquires the weight data of the battery 200 under test, the back-end processing system uses the serial number of the scanned QR code as a unique identifier to directly push the weight data to the LIMS. This improves the accuracy of weight data input and simultaneously enables automatic association between the weight data and the appearance image of the battery 200 under test, ensuring traceability integrity.

[0038] According to some embodiments of this utility model, the detection component 2 further includes a drive unit 23 and a distance sensor 24. The distance sensor 24 is used to measure the distance between the appearance detection module 22 and the weighing platform 21. The drive unit 23 is connected to the appearance detection module 22 and is at least used to drive the appearance detection module 22 closer to or further away from the weighing platform 21. The appearance detection module 22 is also used to scan the QR code on the battery under test 200. Therefore, the accuracy of the battery detection device 100 in detecting the battery under test 200 can be significantly improved.

[0039] In some embodiments, the drive unit 23 includes a drive motor 231, a reducer 232, and a lead screw and slide rail module 233. The output shaft of the drive motor 231 is connected to the lead screw of the lead screw and slide rail module through the reducer 232. The appearance inspection module 22 is located on the slide rail of the lead screw and slide rail module. By adjusting the reduction ratio of the drive motor 231 to the lead screw through the reducer 232, the rotation axis of the lead screw extends in the vertical direction, thereby driving the appearance inspection module 22 to move in the vertical direction through the rotation of the lead screw.

[0040] According to some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the appearance inspection module 22 includes a camera 221 and a supplementary light 222. The weighing platform 21 has a placement area for placing the battery under test 200, and the supplementary light 222 is used to emit light towards the placement area. Therefore, after the battery under test 200 is placed on the placement area, the supplementary light 222 can effectively increase the brightness of the battery under test 200 by emitting light towards the placement area, thereby increasing the brightness of the photo of the battery under test 200 taken by the camera 221, and thus improving the clarity of the obtained appearance image of the battery under test 200.

[0041] According to some embodiments of this utility model, a fill light 222 is disposed on the camera 221, and the fill light 222 is ring-shaped and surrounds the outer periphery of the camera 221. This can effectively increase the fill light area of ​​the fill light 222, and the light emitted by the fill light 222 can more evenly increase the brightness of the placement area, thereby improving the clarity of the images captured by the camera 221.

[0042] According to some embodiments of this utility model, the supplementary light 222 is a soft light. That is, the color temperature of the supplementary light 222 is adjustable. Therefore, the color temperature of the supplementary light 222 can be flexibly adjusted according to shooting requirements and ambient brightness to improve the clarity of the image of the test casing. Furthermore, the light emitted by the soft light is relatively gentle, which can reduce eye strain on the operator and eliminate shadows during shooting, thereby reducing glare caused by supplementary lighting and improving the clarity of the image of the test battery 200.

[0043] According to some embodiments of this utility model, a fill light 222 is disposed on the camera 221. The fill light 222 is ring-shaped and surrounds the outer periphery of the camera 221, and the fill light 222 is a soft light. This effectively reduces glare during shooting and improves the clarity of the captured image of the battery under test 200.

[0044] In some embodiments, the appearance inspection module 22 further includes a zoom lens 223 and a mounting base 224. The supplementary light 222, camera 221, and range sensor 24 are all mounted on the mounting base 224. The zoom lens 223 is mounted on the image side of the camera 221 to enhance its zoom capability. The camera 221 can be an industrial camera. Specifically, after scanning the identification QR code of the battery under test 200, the back-end processing system controls the drive unit 23 according to preset parameters (e.g., different parameters for square or cylindrical batteries) to adjust the camera 221 to the optimal shooting height. When encountering a new model of battery under test 200 for the first time, the range sensor 24 assists the camera 221 in determining the ideal focal length, such as 350mm, and records the parameters via the PLC. This allows for direct use of the same model of battery under test 200 during subsequent inspections, reducing the single focusing time from 30 seconds of manual adjustment to within 2 seconds, thereby improving inspection efficiency.

[0045] According to some embodiments of this utility model, such as Figure 2 , Figure 3 and Figure 6As shown, a detection space 11 is formed within the frame 1, and a detection component 2 is disposed within the detection space 11. A pick-and-place port 12 communicating with the detection space 11 is formed on the frame 1. The detection component 2 also includes a lighting module 25, which is disposed within the detection space 11 and used to illuminate the detection space 11. In other words, the process of the battery detection device 100 detecting the battery 200 to be tested is carried out in the detection space 11. The battery 200 to be tested can be placed into the weighing platform 21 within the detection space 11 through the pick-and-place port 12, and can be removed from the weighing platform 21 through the pick-and-place port 12 after the test is completed.

[0046] By setting up the detection space 11, interference from the external environment during the detection process of the battery under test 200 can be effectively reduced, thereby improving the accuracy of the battery detection device 100 in detecting the battery under test 200. Furthermore, by setting up the illumination module 25, the brightness of the detection space 11 can be effectively increased, ensuring sufficient brightness within the detection space 11. This increases the amount of light entering the appearance detection module 22, thereby improving the clarity of the appearance image of the battery under test acquired by the appearance detection module 22.

[0047] According to some embodiments of this utility model, the lighting module 25 includes a light-emitting element 251 and a diffuser 252. The light-emitting element 251 is disposed on the inner wall surface of the detection space 11, and the diffuser 252 is disposed on the side of the light-emitting element 251 facing the detection space 11. That is, the light emitted by the light-emitting element passes through the diffuser 252 and enters the detection space 11 to illuminate the detection space 11. The diffuser 252 makes the light entering the detection space 11 more uniform and softer, thereby reducing glare and avoiding discomfort to the operator caused by glare. In addition, the lighting module 25 can uniformly illuminate the detection space 11, thereby reducing shadows on the battery under test 200 and improving the clarity of the appearance image of the battery under test 200 acquired by the appearance acquisition module.

[0048] According to some embodiments of this utility model, such as Figure 6 As shown, the light-emitting element 251 includes multiple light strips 2511 extending horizontally, with the multiple light strips 2511 located on the same side of the weighing platform 21 arranged at intervals in the vertical direction. That is, the detection space 11 is provided with multiple light strips 2511 arranged at intervals in the vertical direction. This effectively increases the light-emitting position of the lighting module 25, allowing the lighting module 25 to illuminate the detection space 11 more evenly and comprehensively. Furthermore, the interval arrangement of the multiple light strips 2511 ensures a uniform distribution of the light emitted by the multiple light strips 2511, thereby improving the effect of the lighting module 25 in illuminating the detection space 11. In a specific example, multiple light strips 2511 arranged at even intervals in the vertical direction are provided on the left, right, and rear sides of the weighing platform 21, which can further improve the uniformity of the lighting module 25 in illuminating the detection space 11.

[0049] According to some embodiments of this utility model, such as Figure 1 and Figure 7 As shown, the rack 1 is equipped with an observation window 13, which is located on the same side of the rack 1 as the pick-up / placement port 12, and is positioned above the pick-up / placement port 12. This allows the operator to easily observe the situation within the testing space 11 from the outside, such as whether the battery under test 200 is properly positioned, thus improving the accuracy of subsequent testing of the battery under test 200 by the testing component 2. Furthermore, the fact that the observation window 13 and the pick-up / placement port 12 are located on the same side of the rack 1 allows the operator to pick up / place and observe the battery from the same side of the rack 1, reducing the difficulty of operation. Also, the observation window 13 is positioned relatively high, while the pick-up / placement port 12 is positioned relatively low, allowing the operator to see the battery under test 200 within the testing space 11 through the observation window 13 without bending or squatting.

[0050] According to some embodiments of this utility model, such as Figure 7 As shown, the observation window 13 includes an outer frame 131 and a window 132 disposed within the outer frame 131. The window 132 is a semi-transparent component. That is, the operator can observe the battery 200 under test in the detection space 11 from the outside of the window 132. At the same time, the window 132 can block a portion of the light from entering the operator's eyes, thereby effectively avoiding glare when the operator observes the battery 200 under test, thus improving the operator's comfort during operation.

[0051] In one specific example, the window 132 is a semi-transparent acrylic sheet, which is lightweight and not easily broken, thus preventing the window 132 from breaking and scratching the operator, thereby improving the safety of the battery detection device 100.

[0052] According to some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the battery testing device 100 also includes an operation panel 3, which is mounted on the frame 1 and located outside the testing space 11. The operation panel 3 is electrically connected to the testing component 2 and is positioned above the weighing platform 21. Therefore, the operator can control the testing component 2 from outside the testing space 11 via the operation panel 3. For example, the image acquired by the appearance inspection module 22 can be transmitted to the operation panel 3, allowing the operator to directly observe the shooting status of the appearance inspection module 22 through the operation panel 3. This reduces the difficulty of operation for the operator and improves the efficiency of battery testing by the battery testing device 100.

[0053] According to some embodiments of this utility model, such as Figure 1 and Figure 2As shown, the battery testing device 100 also includes an operation panel 3. The operation panel 3 is located on the frame 1 and outside the testing space 11. The operation panel 3 is electrically connected to the testing component 2. The testing space 11 has two components arranged along the second direction. Each testing space 11 has a corresponding testing component 2. There are two operation panels 3. The two operation panels 3 correspond one-to-one with the two testing components 2. The two operation panels 3 are located on opposite sides of the frame 1 along the second direction.

[0054] In other words, the two detection components 2 can be operated through two operation panels 3 respectively. By setting the two operation panels 3 on opposite sides of the frame 1, more space can be provided for the operation of the operation panels 3. For example, two operators can stand on opposite sides of the frame 1 along the second direction and use the operation panels 3 on both sides respectively, so as to improve the practicality and convenience of the battery detection device 100.

[0055] According to some embodiments of this utility model, the battery testing device 100 further includes an operation panel 3. The operation panel 3 is disposed on the frame 1 and located outside the testing space 11. The operation panel 3 is electrically connected to the testing component 2. The operation panel 3 is located above the weighing platform 21. The testing space 11 has two components arranged along the second direction. Each testing space 11 has a corresponding testing component 2. There are two operation panels 3, each corresponding to one of the two testing components 2. The two operation panels 3 are located on opposite sides of the frame 1 along the second direction. This facilitates the operator's control of the testing component 2, reducing the difficulty of using the battery testing device 100. According to some embodiments of this utility model, such as Figure 2 , Figure 3 and Figure 8 As shown, multiple detection spaces 11, pick-up / placement ports 12, and detection components 2 are provided. Each pick-up / placement port 12, detection component 2, and detection space 11 corresponds to another. The pick-up / placement ports 12 are located on the same side of the frame 1 along the first direction, and the multiple detection spaces 11 and pick-up / placement ports 12 are arranged along the second direction. The first direction, the second direction, and the up / down direction are perpendicular to each other. In other words, each detection space 11 can be tested by the corresponding detection component 2 on the battery 200 to be tested. Thus, the battery detection device 100 can simultaneously perform detection operations on multiple batteries, improving detection efficiency.

[0056] In a specific example, there are two detection spaces 11, two pick-up and drop-off ports 12, and two detection components 2. The dimensions of the frame 1 are 1720m × 0.8m × 2.3m, and the height of the weighing platform 21 is 0.6m.

[0057] According to some embodiments of this utility model, such as Figure 8 and Figure 9As shown, the loading and unloading port 12 is formed on the front side of the frame 1. The frame 1 includes an outer shell 14 and an inner frame 15. The inner frame 15 is disposed inside the outer shell 14. The outer shell 14 includes a first side plate 141, a second side plate 142, a back plate 143, and a top cover 144. The first side plate 141 and the second side plate 142 are located on the left and right sides of the inner frame 15, respectively. The back plate 143 is located on the rear side of the inner frame 15, and the top cover 144 is located on the top of the inner frame 15. The first side plate 141, the second side plate 142, the back plate 143, and the top cover 144 are all opaque material parts. In other words, the first side panel 141, the second side panel 142, the back panel 143, and the top cover 144 are all opaque. Thus, while creating a more independent detection space 11 for battery testing through the first side panel 141, the second side panel 142, the back panel 143, and the top cover 144, the light in the detection space 11 is prevented from scattering outward, thereby reducing the problem of glare for operators caused by the light in the detection space 11.

[0058] In some embodiments, the bottom of the frame 1 is provided with casters, so that the battery detection device 100 can slide by means of the casters, making it easy to adjust the position of the battery detection device 100.
