[0001] This application relates to the field of battery manufacturing technology, specifically to a testing institution and a testing system. Background Technology

[0002] In the lithium-ion battery production and assembly process, the battery cell is first installed into a casing with one open end. Then, a top cover is used to seal the opening of the casing. The top cover has a pre-drilled injection hole, through which electrolyte is injected into the casing to wet the battery cell. To maintain the pressure environment inside the casing and prevent external gases and moisture from entering the battery cell, a sealing pin is usually placed in the injection hole and welded to the top cover to seal the injection hole.

[0003] The relevant technologies for defect detection in lithium-ion batteries mainly employ inspection mechanisms composed of 2D and 3D cameras. These mechanisms can only detect defects such as blackening, pinholes, dents, weld beads, weld spalling, broken welds, weld misalignment errors, and warped nails. They cannot detect cracks in the sealing nail welds, which can easily lead to leakage in lithium-ion batteries. Utility Model Content

[0086] Firstly, please see Figures 1 to 7 This application provides a testing mechanism 10, which can be used to detect weld cracks on battery A. As an example, battery A includes a lithium-ion battery.

[0087] Specifically, the testing mechanism 10 includes a base 11, a testing device 12, a first moving device 13, and a first mounting device 14. The testing device 12, the first moving device 13, and the first mounting device 14 are disposed on the base 11, and the base 11 provides support for the testing device 12, the first moving device 13, and the first mounting device 14.

[0088] The base 11 has a first region 101. Typically, the first region 101 is a local area of ​​the base 11 (e.g., ...). Figure 1 (As shown by the dashed line). As an example, the base 11 has two opposing side surfaces, namely a first side surface and a second side surface. When the detection mechanism 10 is in normal use, the first side surface faces the ground, and the second side surface forms a support surface. The first region 101 is a local area on the second side surface.

[0089] The detection device 12 is mounted on the base 11. Specifically, the detection device 12 includes a first support frame 121 and a spectral confocal displacement sensor 122. The first support frame 121 is mounted on the first region 101, and the spectral confocal displacement sensor 122 is mounted on the first support frame 121 and spaced apart from the base 11. It is foreseeable that the spectral confocal displacement sensor 122 corresponds to the first region 101, and can detect objects located in the first region 101.

[0090] The Spectral Confocal Displacement Sensor 122 is a high-precision measuring device based on optical principles. Utilizing the interference effect of lasers and spectral analysis technology, it can accurately measure parameters such as the surface morphology of objects. Therefore, the Spectral Confocal Displacement Sensor 122 can be used to detect weld cracks on object surfaces. Due to its advantages of high precision, high stability, and non-contact measurement, the Spectral Confocal Displacement Sensor 122 has a low false negative rate when used for weld crack detection. Furthermore, the Spectral Confocal Displacement Sensor 122 can also detect blackening, pinholes, pits, weld beads, weld spatter, broken welds, weld misalignment errors, and warped defects. Thus, the Spectral Confocal Displacement Sensor 122 can replace a 2D camera + 3D camera, simplifying the structure of the detection mechanism 10. In other words, the Spectral Confocal Displacement Sensor 122 has richer functionality compared to a 2D camera + 3D camera.

[0091] The first moving device 13 refers to a device for moving the first mounting device 14. Specifically, the first moving device 13 is disposed on the base 11, and a portion of the first moving device 13 extends into the first region 101. As an example, the first moving device 13 is elongated, with one end of the first moving device 13 located within the first region 101.

[0092] The first mounting device 14 refers to a device for carrying battery A. The first mounting device 14 is disposed on the first moving device 13, meaning it is indirectly disposed on the base 11. The first mounting device 14 is disposed on the base 11 via the first moving device 13. The first moving device 13 can move the first mounting device 14 on the base 11. Specifically, the first moving device 13 can move the first mounting device 14 along a first direction into the first region 101. When the first mounting device 14 moves into the first region 101, it is located between the spectral confocal displacement sensor 122 and the base 11. Thus, when battery A is carried on the first mounting device 14, the spectral confocal displacement sensor 122 can detect battery A on the first mounting device 14. As an example, the first moving device 13 is linear, and the first direction is consistent with the extension direction of the first moving device 13. Optionally, the first moving device 13 can also move the first mounting device 14 in the opposite direction of the first direction to move away from the first region 101. That is, the first moving device 13 can drive the first mounting device 14 to reciprocate in a first direction. As an example, the following will use... Figures 2-3 The X-axis direction is taken as the first direction.

[0093] For example, see Figure 2 and Figure 3 When testing battery A using the testing mechanism 10, the first mounting device 14 is kept at the starting position of the first moving device 13 away from the first region 101, which facilitates loading battery A onto the first mounting device 14. Then, the first moving device 13 drives the first mounting device 14 to move along the first direction to the measurement point in the first region 101, so that battery A is located below the spectral confocal displacement sensor 122. The spectral confocal displacement sensor 122 is activated to test battery A. After the test is completed, the first moving device 13 drives the first mounting device 14 to move in the opposite direction of the first direction back to the starting point.

[0094] The detection mechanism 10 provided in this embodiment uses a first mounting device 14 to load battery A, and then a first moving device 13 moves the first mounting device 14 to transfer battery A to a position corresponding to the spectral confocal displacement sensor 122, thereby facilitating the detection of battery A using the spectral confocal displacement sensor 122. Compared with the related technologies that use 2D and 3D cameras to detect battery A, the use of the spectral confocal displacement sensor 122 can not only detect defects such as blackening, pinholes, dents, weld beads, weld explosions, broken welds, weld misalignment errors, and warped nails, but also detect weld cracks, further enriching the functionality of the detection mechanism 10 and reducing the risk of missing defective batteries A.

[0095] In some implementations, please refer to Figure 3 The detection device 12 also includes a first lifting module 123, which is mounted on the first support frame 121 and connected to the dynamic spectral confocal displacement sensor 122. The first lifting module 123 drives the spectral confocal displacement sensor 122 to move up and down, specifically moving it in a second direction to move closer to or further away from the base 11, where the second direction intersects with the first direction. This arrangement allows the detection device 12 to accommodate more batteries of different sizes, improving the reliability of the detection results. When the spectral confocal displacement sensor 122 detects battery A, the distance between it and the battery A is usually set to a fixed value to ensure the reliability of the results. However, different models of batteries A have different sizes, and even batteries of the same model may have errors due to manufacturing processes, leading to different distances between the spectral confocal displacement sensor 122 and the battery A. By mounting the first lifting module 123 on the first support frame 121 to drive the spectral confocal displacement sensor 122 to move up and down, the distance between the spectral confocal displacement sensor 122 and the battery A can be adjusted. For example, when battery A is relatively high, the first lifting module 123 can be used to move the spectral confocal displacement sensor 122 away from the base 11. Conversely, when battery A is relatively low, the first lifting module 123 can be used to move the spectral confocal displacement sensor 122 closer to the base 11, thus maintaining the same or nearly equal distance between the spectral confocal displacement sensor 122 and battery A. Optionally, the second direction is perpendicular to the first direction. As an example, using... Figure 3 The Z-axis direction is used as the second direction.

[0096] In some implementations, please refer to Figure 3The detection device 12 has two first support frames 121, which are erected face-to-face on the base 11. Each first support frame 121 includes a first column 1211, a first crossbar 1212, and a second column 1213 connected in sequence. The first column 1211 and the second column 1213 are erected at intervals on the first region 101 of the base 11. The first crossbar 1212 is connected to the top of the first column 1211 and the second column 1213, thus making the first support frame 121 U-shaped.

[0097] The detection device 12 also has two first lifting modules 123, which are respectively arranged facing each other on two first support frames 121. That is, one first lifting module 123 is set on one first support frame 121 and aligned with the other first lifting module 123 set on the other first support frame 121. The first lifting module 123 includes a first fixing plate 1231, a first motor 1232, and a first carrier plate 1233. One end of the first fixing plate 1231 is fixed to the first crossbar 1212, and the first motor 1232 is fixed to the other end of the first fixing plate 1231. The first carrier plate 1233 is movably set on the side of the first fixing plate 1231 facing the other first support frame 121. The first carrier plate 1233 is connected to the output shaft of the first motor 1232 and to the spectral confocal displacement sensor 122. In this way, the first motor 1232 can drive the first carrier plate 1233 to move up and down, thereby driving the spectral confocal displacement sensor 122 to move up and down.

[0098] In some implementations, please refer to Figure 3 and Figure 7The detection device 12 also includes a distance sensor 124 and a first controller 125. The distance sensor 124 is mounted on the first support frame 121 and is used to detect the distance between the distance sensor 124 and the battery A carried in the first mounting device 14. The first controller 125 is communicatively connected to the distance sensor 124 and the first lifting module 123. The first controller 125 is used to control the amount by which the first lifting module 123 moves the spectral confocal displacement sensor 122 based on the distance detection result obtained by the distance sensor 124. The advantage of this setup is that it allows for automated adjustment of the lifting amount of the spectral confocal displacement sensor 122, improving the efficiency of battery A detection. For example, when the distance between the distance sensor 124 and the battery A carried in the first mounting device 14 is large, the first lifting module 123 can be used to move the spectral confocal displacement sensor 122 closer to the base 11. Conversely, when the distance between the distance sensor 124 and the battery A carried in the first mounting device 14 is small, the first lifting module 123 can be used to move the spectral confocal displacement sensor 122 away from the base 11, thereby maintaining the same or close distance between the spectral confocal displacement sensor 122 and the battery A. Furthermore, by using the distance sensor 124 to detect the distance to the battery A mounted in the first mounting device 14, the influence of installation errors of the battery A in the first mounting device 14 on the detection results of the spectral confocal displacement sensor 122 can be reduced.

[0099] In some implementations, please refer to Figure 3 With the first support frame 121 including a first column 1211, a first crossbar 1212, and a second column 1213, the distance sensor 124 is mounted on the first crossbar 1212 and faces the first region 101. The distance sensor 124 is a non-contact distance sensor, such as a lidar, ultrasonic sensor, or photoelectric sensor. The detection device 12 also includes a first controller 125. The location of the first controller 125 is not limited; it can be mounted on the base 11 or on the first support frame 121. The first controller 125 is electrically connected to the distance sensor 124 and the first motor 1232 in the first lifting module 123.

[0100] In some implementations, please refer to Figures 1 to 3The detection mechanism 10 also includes a second moving device 15. A first mounting device 14 is mounted on the second moving device 15, and the second moving device 15 is mounted on the first moving device 13. The second moving device 15 is used to move the first mounting device 14 upward in a third direction, which intersects with both the first and second directions. That is, the third direction is different from both the first and second directions. By using the second moving device 15, the first mounting device 14 can be moved upward in a third direction. The second moving device 15 is mounted on the first moving device 13, and the first moving device 13 moves the second moving device 15 in the first direction, thereby moving the first mounting device 14 in the first direction. By utilizing the cooperation of the first moving device 13 and the second moving device 15, the spectral confocal displacement sensor 122 can scan the battery A carried on the first mounting device 14, enabling detection of multiple positions of the battery A. Optionally, the third direction is perpendicular to both the first and second directions, and the first direction is perpendicular to the second direction. As an example, Figure 2 and Figure 3 The Y-axis direction is taken as the third direction. Optionally, the second moving device 15 drives the first mounting device 14 to move in the third direction, including the second moving device 15 driving the first mounting device 14 to move in both the forward and reverse directions in the third direction.

[0101] For example, see Figure 2 and Figure 3 The first moving device 13 includes a linear motor extending along a first direction (e.g., the X-axis direction), and the second moving device 15 includes a linear motor extending along a third direction (e.g., the Y-axis direction). By employing a linear motor drive method, repeatability accuracy ≤ ±0.01 mm can be guaranteed when detecting battery A, ensuring the accuracy and reliability of the detection.

[0102] In some implementations, please refer to Figure 3The first mounting device 14 includes a first mounting base 141, a retaining wall 142, and a first pushing assembly 143. The first mounting base 141 is used to support the battery A, the retaining wall 142 is fixed on the first mounting base 141, and the first pushing assembly 143 is disposed opposite to the retaining wall 142. The first pushing assembly 143 includes a first driving member 1431 and a first pushing plate 1432. The first driving member 1431 is fixed on the first mounting base 141, and the first driving member 1431 is connected to the first pushing plate 1432 and is used to drive the first pushing plate 1432 to move along a fourth direction so that the first pushing plate 1432 and the retaining wall 142 jointly clamp the battery A. The fourth direction is the direction from the first pushing assembly 143 to the retaining wall 142. By configuring the first mounting device 14 to include a first mounting base 141, a retaining wall 142, and a first pushing assembly 143, the first mounting base 141 supports the bottom of the battery A, and the first pushing assembly 143 and the retaining wall 142 clamp and fix the battery A from both sides. By adjusting the distance between the first pushing plate 1432 and the retaining wall 142, the first mounting device 14 can be adapted to batteries A of different sizes, improving the versatility of the first mounting device 14. Optionally, the first driving member 1431 is also used to drive the first pushing plate 1432 to move in the opposite direction of the fourth direction, thereby canceling the clamping of the battery A by the first pushing plate 1432 and the retaining wall 142, making it easier to remove the battery A from the first mounting device 14 after the test is completed. As an example, the first driving member 1431 includes at least one of a motor and a cylinder.

[0103] In some embodiments, a first mounting base 141 is disposed on a second moving device 15, and a retaining wall 142 and a first pushing assembly 143 are disposed on the side of the first mounting base 141 away from the second moving device 15. There are two retaining walls 142, spaced apart and erected on the first mounting base 141. There is one first pushing assembly 143, meaning there is one first driving member 1431 and one first push plate 1432, but the two ends of the first push plate 1432 extend to correspond to the two retaining walls 142 respectively. In other words, in this case, the two retaining walls 142 share one first pushing assembly 143, and the first mounting base 141 can support two batteries A at a time. As an example, the first driving member 1431 is a three-axis cylinder, and the output end of the three-axis cylinder is connected to the first push plate 1432 and pushes the first push plate 1432 to move along a fourth direction. Here, the fourth direction is the Y-axis direction. It can be understood that if the third direction is also the Y-axis direction, the fourth direction is the same as the third direction. Of course, in some embodiments, the fourth direction may be different from the third direction.

[0104] In some implementations, please refer to Figure 3The first mounting device 14 further includes a second pushing assembly 144 and a third pushing assembly 145. Along the fifth direction, the second pushing assembly 144 and the third pushing assembly 145 are arranged face-to-face at intervals, with the fifth direction perpendicular to the fourth direction. The second pushing assembly 144 includes a second driving member 1441 and a second pushing plate 1442. The second driving member 1441 is fixed to the first mounting base 141 and is connected to the second pushing plate 1442, driving the second pushing plate 1442 to move along the fifth direction. The third pushing assembly 145 includes a third driving member 1451 and a third pushing plate 1452. The third driving member 1451 is fixed to the first mounting base 141 and is connected to the third pushing plate 1452, driving the third pushing plate 1452 to move in the opposite direction of the fifth direction, so that the third pushing plate 1452 and the second pushing plate 1442 together clamp the battery A. When using the first mounting device 14, battery A is supported on the first mounting base 141. Then, the retaining wall 142 and the first pushing assembly 143 are used to abut and limit the battery A on both sides in the fourth direction. The second pushing assembly 144 and the third pushing assembly 145 are used to abut and limit the battery A on both sides in the fifth direction, and the fifth direction is perpendicular to the fourth direction. This achieves the limitation of the battery A on all four sides, improving the stability of the battery A installed on the first mounting device 14. In addition, the battery A can also be positioned by adjusting the second driving member 1441 and the third driving member 1451. Optionally, the second driving member 1441 is also used to drive the second push plate 1442 to move in the opposite direction of the fifth direction, and the third driving member 1451 is also used to drive the third push plate 1452 to move in the fifth direction. This makes it easier to remove the clamping of the battery A by the second push plate 1442 and the third push plate 1452, and facilitates the removal of the battery A from the first mounting device 14 after the battery A has been tested. If the fifth direction is perpendicular to the fourth direction, then when the fourth direction is the same as the third direction and the first direction is perpendicular to the third direction, the fifth direction can be the same as the first direction. Here, the second drive member 1441 and the third drive member 1451 can be the same or different. As an example, the second drive member 1441 includes at least one of a motor and a cylinder. The third drive member 1451 includes at least one of a motor and a cylinder. As an example, the second drive member 1441 includes a thin-film cylinder, and the third drive member 1451 includes a positioning cylinder.

[0105] Secondly, please see Figure 4 This application embodiment also provides a detection system 100, which includes the above-mentioned detection mechanism 10.

[0106] In some implementations, please refer to Figure 4 and Figure 5 The detection system 100 also includes a storage mechanism 20, in which the battery A that has been detected by the detection mechanism 10 can be stored.

[0107] Specifically, the storage mechanism 20 includes a first mounting frame 21, a second mounting device 22, a third moving device 23, and a storage device 24. The third moving device 23 and the storage device 24 are sequentially arranged on the first mounting frame 21 along the sixth direction. The second mounting device 22 is arranged on the third moving device 23. The third moving device 23 is used to drive the second mounting device 22 to move along the seventh direction, which intersects with the sixth direction. Storage positions 240 are distributed on the storage device 24. The second mounting device 22 includes a second mounting base 221 and a fourth pushing assembly 222. The second mounting base 221 is used to support the battery A that has been detected by the detection mechanism 10. The fourth pushing assembly 222 is arranged on the second mounting base 221 and is used to push the battery A from the second mounting base 221 to the storage position 240 along the sixth direction.

[0108] As an example, when the detection system 100 is working, the battery A that has been detected by the detection agency 10 is first transferred to the second mounting base 221 of the second mounting device 22. Then, the third moving device 23 drives the second mounting device 22 to move along the seventh direction until the battery A corresponds to the empty storage position 240. The fourth pushing component 222 pushes the battery A from the second mounting base 221 to the storage position 240 along the sixth direction.

[0109] Optionally, the seventh direction is perpendicular to the sixth direction. See [example image / description]. Figure 5 The sixth direction is the opposite direction of the Y-axis, and the seventh direction is the opposite direction of the X-axis.

[0110] As an example, the third moving device 23 includes a linear motor extending in the seventh direction.

[0111] In some implementations, please refer to Figure 5 and Figure 7 The system has multiple storage positions 240, which are arranged sequentially along the seventh direction. The detection system 100 also includes a second controller 30, which is communicatively connected to the storage mechanism 20 and the detection mechanism 10. The second controller 30 is used to acquire the detection results of the spectral confocal displacement sensor 122 on battery A, and also to control the third moving device 23 and the fourth pushing assembly 222 based on the results to push battery A to the storage position 240 corresponding to the results. This configuration allows for automatic screening of batteries A detected by the detection mechanism 10, improving production efficiency.

[0112] As an example, when the detection system 100 is working, the spectral confocal displacement sensor 122 in the detection mechanism 10 first detects battery A and obtains the detection results. For example, the detection results include OK and NG (No good). OK means that battery A is a good product, that is, there is no target defect on battery A, such as weld cracks. NG means that battery A is a defective product with a defect, that is, the target defect appears on battery A, such as weld cracks. Correspondingly, the storage mechanism 20 is provided with multiple storage positions 240, for example, two storage positions 240. One storage position 240 is used to store good products, called the first type of storage position, and the other storage position 240 is used to store defective products, called the second type of storage position. At the same time, the second controller 30 also stores the mapping relationship between the detection results of battery A and the storage positions 240. When battery A is transferred to the storage mechanism 20, the second controller 30 first obtains the detection result of battery A, and then controls the third moving device 23 and the fourth pushing assembly 222 to push battery A to the corresponding storage position 240 according to the mapping relationship. For example, when battery A is a good product, the second controller 30 controls the third moving device 23 to move the second mounting device 22 carrying battery A to the position corresponding to the first type of storage position, and then activates the fourth pushing component 222 to push battery A to the first type of storage position for storage; when battery A is a defective product, the second controller 30 controls the third moving device 23 to move the second mounting device 22 carrying battery A to the position corresponding to the second type of storage position, and then activates the fourth pushing component 222 to push battery A to the second type of storage position for storage.

[0113] In some implementations, please refer to Figure 5 The second mounting base 221 has a mounting groove 221a extending in the sixth direction for accommodating battery A. An outlet 221b is formed at the end of the mounting groove 221a facing the storage device 24. The fourth pushing assembly 222 includes a fourth driving member 2221 and a fourth push plate 2222. The fourth push plate 2222 is disposed corresponding to the mounting groove 221a. The fourth driving member 2221 is connected to the fourth push plate 2222, and the fourth driving member 2221 is used to drive the fourth push plate 2222 to move in the sixth direction to push battery A out of the outlet 221b from the mounting groove 221a (e.g., ...). Figure 5 The dashed line shows the state of battery A before it is pushed out, and the solid line shows the state of battery A after it is pushed out. By providing a mounting slot 221a to accommodate battery A, the risk of battery A tipping over on the second mounting base 221 is reduced. An outlet 221b is provided on the mounting slot 221a, and the fourth pushing assembly 222 can automatically push battery A out of the mounting slot 221a from the outlet 221b, improving detection efficiency. It can be understood that when the fourth pushing assembly 222 pushes battery A, the fourth push plate 2222 is located on the side of battery A away from the outlet 221b. The number of mounting slots 221a can be one or more.

[0114] To ensure that battery A can be smoothly pushed from the mounting slot 221a to the storage position 240, the bottom wall surface of the mounting slot 221a is flush with or higher than the surface of the storage position 240. Optionally, the outlet 221b of the mounting slot 221a is close to the storage position 240, or a connecting plate is provided between the outlet 221b of the mounting slot 221a and the storage position 240, the surface of the connecting plate being flush with or lower than the bottom wall surface of the mounting slot 221a. Optionally, the fourth push plate 2222 extends at least partially into the mounting slot 221a, ensuring that the fourth push plate 2222 can accommodate batteries A of different heights. When the fourth drive member 2221 drives the fourth push plate 2222 to move, the fourth push plate 2222 moves within the mounting slot 221a.

[0115] Optionally, the fourth drive member 2221 includes at least one of a motor and a cylinder. As an example, the fourth drive member 2221 includes a rodless cylinder disposed on the second mounting base 221 and located outside the mounting groove 221a, the extension direction of the rodless cylinder being consistent with the extension direction of the mounting groove 221a, that is, the rodless cylinder extending along the sixth direction.

[0116] In some implementations, please refer to Figure 5 The storage device 24 includes a second support frame 241, a fifth drive member 242, and a first conveyor belt 243. The second support frame 241 is mounted on the first mounting frame 21, and the fifth drive member 242 is mounted on the second support frame 241. The storage position 240 is located on the first conveyor belt 243. The fifth drive member 242 is connected to the first conveyor belt 243 and is used to drive the first conveyor belt 243 to move, thereby moving the battery A along the sixth direction. In this way, when the battery A is pushed onto the storage position 240 by the fourth push assembly 222 from the second mounting device 22, that is, when the battery A is carried on the first conveyor belt 243, the fifth drive member 242 drives the first conveyor belt 243, which can move the battery A away from the second mounting device 22, thereby freeing up the position of the first conveyor belt 243 close to the second mounting device 22, so that the next battery A can be pushed onto the storage position 240 by the fourth push assembly 222.

[0117] Optionally, the fifth drive unit 242 includes a rotary motor, and the first conveyor belt 243 is sleeved on the output shaft of the rotary motor, so that the first conveyor belt 243 can be driven to move when the rotary motor's rotating shaft rotates.

[0118] In some implementations, please refer to Figure 5The storage device 24 also includes a third support frame 244 and an isolation rod 245. The third support frame 244 is disposed on the second support frame 241 and spans the first conveyor belt 243. The isolation rod 245 is disposed on the third support frame 244 and located above the first conveyor belt 243. The isolation rod 245 extends along a sixth direction. There are multiple isolation rods 245, and at least some of the isolation rods 245 are spaced apart along the seventh direction. At least two adjacent and spaced-apart isolation rods 245 define a storage position 240. That is, there is at least one storage position 240. It is understood that the third support frame 244 and the isolation rod 245 will not contact the first conveyor belt 243. Thus, when the first conveyor belt 243 moves, the third support frame 244 and the isolation rod 245 will not interfere with the first conveyor belt 243. In addition, the storage position 240 is defined by two adjacent and spaced-apart isolation rods 245. That is to say, when the battery A is located in the storage position 240, it will be located between the two isolation rods 245. The isolation rods 245 are spaced apart from the surface of the first conveyor belt 243. Thus, the isolation rods 245 can limit and support the battery A to a certain extent, thereby reducing the risk of the battery A tipping over when the first conveyor belt 243 moves.

[0119] For example, see Figure 5 The storage device 24 contains two third support frames 244, which are erected alternately on the second support frame 241. Of course, in other embodiments, the number of third support frames 244 can be one, three, or more. Each third support frame 244 includes a third column 2441, a second crossbar 2442, and a fourth column 2443 connected in sequence. The third column 2441 and the fourth column 2443 are erected alternately on the second support frame 241 and located on opposite sides of the first conveyor belt 243. The second crossbar 2442 is connected to the third column 2441 and its top end, thus positioning the second crossbar 2442 above and across the first conveyor belt 243.

[0120] In addition, the third support frame 244 also includes multiple connecting rods 2444. Optionally, as Figure 5The diagram shows seven connecting rods 2444. In other embodiments, the number of connecting rods 2444 can be two, three, four, five, six, eight, nine, or ten. One end of each connecting rod 2444 is connected to the second crossbar 2442, and the other end extends towards the first conveyor belt 243. The third column 2441 and the fourth column 2443 are of similar length, but the length of the connecting rod 2444 is less than the length of either the third column 2441 or the fourth column 2443, so that the other end of the connecting rod 2444 is suspended above the first conveyor belt 243. Optionally, each connecting rod 2444 is paired with a barrier rod 245, resulting in seven barrier rods 245. Specifically, the other end of each connecting rod 2444 is connected to a barrier rod 245, so that the barrier rod 245 is suspended above the first conveyor belt 243. It should be noted that there are two third support frames 244, and the two third support frames 244 are set in a corresponding manner, that is, the positions of the connecting rods 2444 on different third support frames 244 are corresponding.

[0121] For ease of distinction, the seven connecting rods 2444 distributed sequentially along the seventh direction are referred to as the first connecting rod, the second connecting rod, the third connecting rod, the fourth connecting rod, the fifth connecting rod, the sixth connecting rod, and the seventh connecting rod, respectively; and the seven isolation rods 245 distributed sequentially along the seventh direction are referred to as the first isolation rod, the second isolation rod, the third isolation rod, the fourth isolation rod, the fifth isolation rod, the sixth isolation rod, and the seventh isolation rod, respectively. The first isolation rod is connected to the first connecting rod, the second isolation rod is connected to the second connecting rod, the third isolation rod is connected to the third connecting rod, the fourth isolation rod is connected to the fourth connecting rod, the fifth isolation rod is connected to the fifth connecting rod, the sixth isolation rod is connected to the sixth connecting rod, and the seventh isolation rod is connected to the seventh connecting rod. As shown in the diagram, all isolation bars 245 are arranged at intervals along the seventh direction. However, the interval between the fifth and sixth isolation bars is too small, thus forming five storage positions 240. These five storage positions 240 are: the first storage position between the first and second isolation bars; the second storage position between the second and third isolation bars; the third storage position between the third and fourth isolation bars; the fourth storage position between the fourth and fifth isolation bars; and the fifth storage position between the sixth and seventh isolation bars. The first and second storage positions are second-type storage positions, while the third, fourth, and fifth storage positions are first-type storage positions.

[0122] In some embodiments, rollers 2451 are provided on the isolation rods 245 that at least partially define the storage position 240. In other words, not all isolation rods 245 necessarily define the storage position 240, and not all isolation rods 245 that define the storage position 240 have rollers 2451. By providing rollers 2451 on the isolation rods 245 that at least partially define the storage position 240, when the battery A is pushed onto the storage position 240 and moves under the drive of the first conveyor belt 243, the isolation rods 245 do not move, but the rollers 2451 on the isolation rods 245 can guide the battery A.

[0123] In some embodiments, the third support frame 244 further includes a stop bar 2445. The stop bar 2445 is attached to a plurality of isolation bars 245 and spans at least one storage compartment 240. The stop bar 2445 is generally located away from the second mounting device 22. As an example, see [link to example]. Figure 6 The stop lever 2445 includes a first stop lever and a second stop lever; wherein the first stop lever is located at the end of the isolation lever 245 away from the second mounting device 22, and the first stop lever spans all second-type storage positions; the second stop lever is located at the middle of the isolation lever 245 on the second mounting device 22, and the second stop lever spans all first-type storage positions. By setting the stop lever 2445 to block the battery A on the first conveyor belt 243, the battery A is confined to a fixed position on the storage device 24, so as to facilitate the removal of the battery A from the fixed position.

[0124] In some implementations, please refer to Figure 4 and Figure 6 The testing system 100 also includes a first transfer mechanism 40, which is used to transfer the battery A, which has been tested by the testing mechanism 10, from the first mounting device 14 to the second mounting device 22. By setting the first transfer mechanism 40, the battery A can be automatically transferred from the first mounting device 14 to the second mounting device 22, which can improve production efficiency.

[0125] As an example, the storage mechanism 20 is positioned close to the detection mechanism 10, and the first mounting device 14 is aligned or substantially aligned with the second mounting device 22. The first transfer mechanism 40 is positioned close to the storage mechanism 20 and the detection mechanism 10, which facilitates the transfer of battery A by the first transfer mechanism 40.

[0126] In some implementations, please refer to Figure 6The first transfer mechanism 40 includes a second mounting frame 41, a first transverse module 42, a second lifting module 43, and a first material picking module 44. The first transverse module 42 is mounted on the second mounting frame 41, and the second lifting module 43 is mounted on the first transverse module 42. The first transverse module 42 is used to drive the second lifting module 43 to move above the first mounting device 14 and the second mounting device 22. The first material picking module 44 is mounted on the second lifting module 43, and the second lifting module 43 is used to drive the first material picking module 44 to move up and down in the height direction of the second mounting frame 41.

[0127] When battery A needs to be transferred, the second lifting module 43 is first moved above the first mounting device 14 via the first lateral moving module 42. Then, the second lifting module 43 drives the first picking module 44 to descend until it is close to battery A on the first mounting device 14. The first picking module 44 picks up battery A, and the second lifting module 43 then drives the first picking module 44 to rise. The first lateral moving module 42 then drives the second lifting module 43 to move above the second mounting device 22. Then, the second lifting module 43 drives the first picking module 44 to descend until it is close to the second mounting device 22. The first picking module 44 releases battery A onto the second mounting device 22, and then the second lifting module 43 drives the first picking module 44 to rise again. This completes one transfer process of battery A.

[0128] In some embodiments, the second mounting bracket 41 includes a fifth column 411, a third crossbar 412, and a sixth column 413. The fifth column 411 and the sixth column 413 are spaced apart, and the third crossbar 412 is connected to the top ends of both the fifth column 411 and the sixth column 413. A first lateral movement module 42 is mounted on the third crossbar 412. As an example, the first lateral movement module 42 includes a linear motor, and the second lifting module 43 includes a lifting motor connected to the linear motor. A first material handling module 44 is used to pick up battery A. As an example, the first material handling module 44 is a robotic arm that can pick up battery A by adsorption or clamping.

[0129] In some implementations, please refer to Figure 4 and Figure 7The detection system 100 also includes a transfer mechanism 50 and a welding mechanism 60. The welding mechanism 60 is used to weld battery A, and the transfer mechanism 50 is used to transfer battery A. The welding mechanism 60 is located upstream of the transfer mechanism 50. The first transfer mechanism 40 is also used to transfer battery A from the transfer mechanism 50 to the first mounting device 14. That is, battery A is first welded on the welding mechanism 60, then flows into the transfer mechanism 50, and then is transferred by the first transfer mechanism 40 to the detection mechanism 10 for detection. This makes the process from welding to detecting weld cracks of battery A fully automated, improving the production efficiency of battery A.

[0130] As an example, the transport mechanism 50 can be a production logistics line.

[0131] In some implementations, please refer to Figure 6 The first transfer mechanism 40 also includes a third picking module 45, which is mounted on the second lifting module 43 together with the first picking module 44. The third picking module 45 is spaced apart from the first picking module 44, and the distance between them is exactly equal to the distance between the first mounting device 14 and the second mounting device 22. Compared to the first picking module 44, the third picking module 45 is closer to the detection mechanism 10. The third picking module 45 is used to pick up battery A. As an example, the third picking module 45 is a robotic arm, which can pick up battery A by adsorption or clamping.

[0132] When the detection system 100 is working, the first battery A is first transferred to the first mounting device 14 using the third material handling module 45. Then, the third material handling module 45 returns to the transmission mechanism 50 to pick up the second battery A. After the first battery A has completed the detection, the first material handling module 44 removes the first battery A from the first mounting device 14. The first horizontal moving module 42 drives the second lifting module 43 to move, so that the first material handling module 44 is above the second mounting device 22 and the third material handling module 45 is above the first mounting device 14. The second lifting module 43 drives the third material handling module 45 and the first material handling module 44 to descend together. The third material handling module 45 puts the second battery A into the first mounting device 14, and the first material handling module 44 puts the first battery A into the second mounting device 22. Then, the second lifting module 43 drives the third material handling module 45 and the first material handling module 44 to rise together, thus completing one loading process of battery A.

[0133] In some implementations, please refer to Figure 4The transmission mechanism 50 includes a third mounting bracket 51, a sixth drive member 52, and a second conveyor belt 53. The sixth drive member 52 is mounted on the third mounting bracket 51 and is connected to and drives the second conveyor belt 53 to move. The second conveyor belt 53 carries the battery A. As an example, the sixth drive member 52 includes a rotary motor, and the second conveyor belt 53 is mounted on the output shaft of the rotary motor, so that the second conveyor belt 53 can be driven to move when the rotary motor's shaft rotates.

[0134] As an example, the second mounting bracket 41 spans the transmission mechanism 50, and the fifth column 411 and the sixth column 413 are located on both sides of the second conveyor belt 53, respectively.

[0135] In some implementations, please refer to Figure 4 The detection system 100 also includes a second transfer mechanism 70, which is used to transfer battery A from storage position 240 to transmission mechanism 50, that is, battery A returns to transmission mechanism 50.

[0136] Specifically, the second transfer mechanism 70 includes a fourth mounting frame 71, a second transverse module 72, a third lifting module 73, and a second material picking module 74. The second transverse module 72 is mounted on the fourth mounting frame 71, and the third lifting module 73 is mounted on the second transverse module 72. The second transverse module 72 is used to drive the third lifting module 73 to move above the storage position 240 and the transmission mechanism 50. The second material picking module 74 is mounted on the third lifting module 73, and the third lifting module 73 is used to drive the second material picking module 74 to move up and down in the height direction of the fourth mounting frame 71.

[0137] When it is necessary to transfer battery A, the third lifting module 73 is first moved above the storage position 240 via the second lateral moving module 72 (especially above the first type of storage position, so that the third lifting module 73 corresponds to the second stop). Then, the third lifting module 73 drives the second picking module 74 to descend to the battery A near the storage position 240. The second picking module 74 picks up battery A, and the third lifting module 73 then drives the second picking module 74 to rise. The second lateral moving module 72 then drives the third lifting module 73 to move above the transmission mechanism 50. Then, the third lifting module 73 drives the second picking module 74 to descend to the second conveyor belt 53. The second picking module 74 releases battery A onto the second conveyor belt 53, and then the third lifting module 73 drives the second picking module 74 to rise. This completes one unloading process of battery A.

[0138] In some embodiments, the fourth mounting frame 71 includes a seventh column 711, a fourth crossbar 712, and an eighth column 713. The seventh column 711 and the eighth column 713 are spaced apart, and the fourth crossbar 712 is connected to the top ends of both the seventh column 711 and the eighth column 713. A second lateral movement module 72 is mounted on the fourth crossbar 712. As an example, the second lateral movement module 72 includes a linear motor, and a third lifting module 73 includes a lifting motor connected to the linear motor. A second picking module 74 is used to pick up battery A. As an example, the second picking module 74 is a robotic arm that can pick up battery A by adsorption or clamping. As an example, the fourth mounting frame 71 spans the transmission mechanism 50 and the storage mechanism 20.

[0139] In some implementations, please refer to Figure 7 The detection system 100 also includes a helium detection mechanism 80, located upstream of the transmission mechanism 50. The helium detection mechanism 80 is used to re-detect the battery A flowing out of the transmission mechanism 50. Thus, during the operation of the detection system 100, the path of battery A within the detection system 100 is as follows: Figure 7 As shown by the dashed line: After being welded by the welding mechanism 60, battery A flows into the transmission mechanism 50, and is then loaded from the transmission mechanism 50 by the first transfer mechanism 40 to the detection mechanism 10 for detection. After the detection is completed, battery A is transferred from the detection mechanism 10 to the storage mechanism 20 by the first transfer mechanism 40. Then, battery A is unloaded from the storage mechanism 20 by the second transfer mechanism 70 and returned to the transmission mechanism 50. The transmission mechanism 50 then transmits battery A to the helium detection mechanism 80 for helium detection.
