[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] With the rapid development of the new energy vehicle and energy storage industries, increasingly higher demands are being placed on the production efficiency and quality inspection of battery modules. Traditional battery module assembly and inspection mainly rely on manual visual inspection or simple contact inspection methods. These methods are inefficient, highly subjective, and difficult to guarantee accuracy and consistency. They are also prone to human error, leading to defective products entering the market, causing safety hazards and economic losses. In particular, the accuracy of battery module polarity testing directly affects the normal operation and safety of the battery pack, and manual inspection is highly susceptible to errors.

[0041] Based on this, referring to Figures 1 to 4, this embodiment of the present invention provides a battery module assembly and testing system 10, which includes a frame 100, a tooling tray 200, a transmission device 300, a positioning device 400, a testing optical fiber 500, and a testing device 600; the frame 100 is provided with a testing station; the tooling tray 200 is movably connected to the frame 100 and is used to support the battery module 20 to be tested; the transmission device 300 is connected to the frame 100 and is used to transport the tooling tray 200 to the testing station; the positioning device 400 is connected to the frame. The positioning device 400 is used to fix the tooling tray 200 at the inspection station; the detection fiber 500 is connected to the frame 100, and the detection fiber 500 is located on the side of the inspection station and is used to obtain the position signal of the battery module 20 at the inspection station; the inspection device 600 includes an inspection mounting frame 610, an inspection moving mechanism 620 and an inspection camera 630. The inspection mounting frame 610 is connected to the frame 100, and the inspection moving mechanism 620 is connected to the inspection mounting frame 610 and the inspection camera 630 respectively and is used to drive the inspection camera 630 to move to the inspection station to inspect the battery module 20.

[0042] When using the battery module assembly and testing system 10 of this embodiment, the battery module 20 is first placed on the tooling tray 200. The tooling tray 200 can be moved to the testing station by the cooperation of the transmission device 300 and the tooling tray 200. After the detection fiber optic cable 500 detects that the tooling tray 200 is in place, the positioning device 400 can fix the tooling tray 200 at the testing station. At this time, the detection moving mechanism 620 drives the detection camera 630 to move and align. The detection camera 630 can automatically detect the battery module 20 at the testing station. After the detection is completed, the transmission device 300 can move the battery module 20 to the next station.

[0043] In the battery module assembly and testing system 10 of this embodiment, by setting up a transmission device 300, a positioning device 400, a detection optical fiber 500 and a detection camera 630 in cooperation, the battery module 20 can be automatically tested. Compared with traditional manual testing, it can effectively improve testing efficiency and reduce labor costs.

[0044] Specifically, the transmission device 300 includes a transmission track 310 connected to the frame 100; the tooling tray 200 includes a tray body 210, a positioning block and a guide wheel 220, the guide wheel 220 is rotatably connected to the tray body 210, and the tray body 210 is slidably engaged with the transmission track 310 through the guide wheel 220; the positioning block is connected to the tray body 210; when the positioning device 400 is connected to the tooling tray 200, the positioning device 400 at least partially abuts against the side of the battery module 20 away from the positioning block.

[0045] In this embodiment, the transmission track 310 is provided with grooves corresponding to the tooling tray 200 to ensure that the tooling tray 200 is not easily detached during transmission. In some embodiments, the inner wall surface of the transmission track 310 is coated with a low-friction coefficient material to reduce the frictional resistance of the tooling tray 200 during sliding, thereby improving transmission efficiency. The tray body 210 of the tooling tray 200 can be made of high-strength plastic or metal to ensure good strength and stability during transmission. The positioning block is rectangular in shape. By setting the positioning block to cooperate with the battery module 20, the battery module 20 can be fixed on the tray body 210 when the positioning device 400 contacts the battery module 20. In some embodiments, a rubber pad can also be provided on the side of the positioning block facing the battery module 20 to increase the friction when in contact with the battery module 20, improve positioning accuracy, and avoid squeezing damage to the battery module 20. The guide wheel 220 can be made of polyurethane, which has good wear resistance and elasticity, ensuring that it is not easily worn during long-term use. The diameter of the guide wheel 220 is matched to the width of the transmission track 310 to optimize its sliding performance and stability. Simultaneously, each guide wheel 220 is rotatably connected to the disc body 210 via a bearing component, reducing noise from the tooling pallet 200 during transport. By configuring a positioning device 400 to cooperate with the tooling pallet 200, when the tooling pallet 200 is transported to the inspection station, the positioning device 400 can engage with the positioning block to firmly clamp the battery module 20, preventing displacement during subsequent inspection operations.

[0046] In one embodiment, the positioning device 400 includes a lifting component 410 and a positioning mechanism 420. The lifting component 410 is located at the bottom of the inspection station and is used to lift or lower the tooling tray 200. The positioning mechanism 420 is located at the front of the inspection station and is used to abut against the side of the battery module 20 away from the positioning block.

[0047] In this embodiment, the positioning device 400 includes a lifting assembly 410 and a positioning mechanism 420. The lifting assembly 410 is located at the bottom of the inspection station and is used to lift or lower the tooling tray 200 by hydraulic or electric drive to ensure that the battery module 20 can be moved to the inspection station for alignment with the inspection camera 630 of the inspection device 600, thereby improving inspection accuracy and efficiency. Meanwhile, the positioning mechanism 420 is located at the front of the inspection station and its function is to abut against the side of the battery module 20 away from the positioning block, thereby stabilizing the battery module 20 during inspection and preventing its displacement.

[0048] Specifically, the positioning mechanism 420 includes a positioning mounting frame 421, a positioning moving component 422, and a positioning fixing component 423. The positioning mounting frame 421 is connected to the frame 100 and spans across the testing station, providing necessary support and stability for the entire positioning mechanism 420. The positioning moving component 422 is connected to the positioning mounting frame 421 and the positioning fixing component 423 respectively. The positioning moving component 422 is used to drive the positioning fixing component 423 to move to one side of the tooling tray 200 or away from the tooling tray 200. The positioning fixing component 423 is used to cooperate with the positioning block to clamp or release the battery module 20.

[0049] In this embodiment, by introducing a positioning mounting bracket 421, a positioning moving component 422, and a positioning fixing component 423 into the positioning mechanism 420, precise positioning and stable clamping of the battery module 20 are achieved. First, the design of the positioning mounting bracket 421 ensures the strength and stability of the entire positioning mechanism, thereby improving the positioning accuracy of the battery module 20. Furthermore, the flexibility of the positioning moving component 422 allows the positioning fixing component 423 to be easily moved to one side of the tooling tray 200 or away from it. After the battery module 20 is inspected, the positioning moving component 422 can drive the positioning fixing component 423 to avoid the battery module 20, allowing the transmission device 300 to continue driving the tooling tray 200 along the transmission track 310 to the next station, thus improving production efficiency. Meanwhile, the positioning and fixing component 423 is designed to work in conjunction with the positioning block. When the tooling tray 200 moves the battery module 20 to the testing station, the positioning and fixing component 423 can abut against the side of the battery module 20 away from the positioning block and firmly fix the battery module 20 to the tooling tray 200 to ensure the testing accuracy of the testing device 600.

[0050] Specifically, the positioning and moving component 422 includes a positioning and moving guide rail 4221, a positioning and moving frame 4222, and a positioning and moving cylinder 4223. The positioning and moving guide rail 4221 is connected to the positioning mounting frame 421 and the positioning and moving frame 4222 respectively. The positioning and moving cylinder 4223 is connected to the positioning mounting frame 421 and the positioning and moving frame 4222 respectively. The positioning and fixing component 423 is connected to the positioning and moving frame 4222, and the positioning and moving cylinder 4223 is used to drive the positioning and fixing component 423 to move to one side of the tooling pallet 200 or away from the tooling pallet 200.

[0051] In this embodiment, the precise and stable movement of the positioning and fixing component 423 is achieved by employing a positioning and moving guide rail 4221, a positioning and moving frame 4222, and a positioning and moving cylinder 4223. The positioning and moving guide rail 4221 provides a stable sliding path for the positioning and moving frame 4222, effectively reducing frictional resistance and ensuring the accuracy and rapid response capability of the positioning and fixing component 423 during movement. The positioning and moving cylinder 4223 can drive the positioning and fixing component 423 to move so that it can align with or avoid the battery module 20, thereby improving the working efficiency and accuracy of the entire positioning mechanism 420. This design not only ensures the stability and reliability of the battery module 20 during the positioning process but also reduces positioning errors caused by unstable movement, thus improving the detection accuracy of the battery module 20.

[0052] Furthermore, the positioning and fixing assembly 423 includes a positioning and fixing frame 4231, a positioning and fixing block 4232, and a positioning and fixing cylinder 4233. The positioning and fixing frame 4231 is connected to the positioning and moving frame 4222. The positioning and fixing cylinder 4233 is connected to the positioning and fixing block 4232 and the positioning and fixing frame 4231 respectively and is used to drive the positioning and fixing block 4232 to cooperate with the positioning block to clamp or release the battery module 20.

[0053] By designing the positioning and fixing assembly 423 as consisting of a positioning and fixing frame 4231, a positioning and fixing block 4232, and a positioning and fixing cylinder 4233, this technical solution achieves a more flexible and efficient fixing and releasing process for the battery module 20. The positioning and fixing frame 4231 is connected to the positioning and moving frame 4222, and is driven to move as a whole by the positioning and moving cylinder 4223. The positioning and fixing cylinder 4233 can precisely control the movement of the positioning and fixing block 4232, enabling it to closely cooperate with the positioning block and effectively clamp or release the battery module 20. This design not only improves the reliability of clamping and prevents detachment or displacement during operation, but also shortens the operation cycle and improves production efficiency through the rapid action of the cylinder. In addition, the flexible operation of the positioning and fixing block 4232 allows the equipment to adapt to battery modules 20 of different specifications or shapes, thereby improving the adaptability and versatility of the battery module assembly and testing system 10, meeting the needs of modern manufacturing for flexibility and efficiency.

[0054] In one embodiment, the positioning block includes a first positioning block 230 and a second positioning block 240. The first positioning block 230 is located on the side of the battery module 20 away from the positioning device 400, and the second positioning block 240 is located on the side adjacent to the first positioning block 230.

[0055] By employing a dual-positioning block structure with a first positioning block 230 and a second positioning block 240, the positioning accuracy and stability of the battery module 20 are effectively improved. The first positioning block 230 is located on the side of the battery module 20 furthest from the positioning device 400, allowing the positioning device 400 to more reliably support the battery module 20 and prevent displacement and tilting due to gravity or external forces. The second positioning block 240, adjacent to the first positioning block 230, further strengthens the constraint on the battery module 20, preventing rotation or lateral movement during positioning and ensuring it is in a precise position, thereby improving detection accuracy and efficiency. This dual-positioning block structure design is particularly suitable for applications requiring high positioning accuracy, effectively avoiding error accumulation caused by a single positioning point, ultimately improving product quality and consistency, and reducing defect rates and rework rates due to poor positioning during production.

[0056] Specifically, the detection fiber 500 includes a through-beam fiber 510 and a fiber mounting bracket 520. The fiber mounting bracket 520 is connected to the rack 100, and the through-beam fiber 510 is detachably connected to the fiber mounting bracket 520.

[0057] In this embodiment, the design of a detachable through-beam fiber 510 and fiber mounting bracket 520 facilitates the installation and maintenance of the through-beam fiber 510, reducing maintenance costs and time. The through-beam fiber 510 can be fixed using screw connections, ensuring the reliability and stability of the connection between the through-beam fiber 510 and the fiber mounting bracket 520, avoiding fiber breakage or signal attenuation due to loosening or detachment. Simultaneously, the adjustability of the through-beam fiber 510 allows this solution to adapt to battery modules 20 of different sizes and specifications, as well as different installation environments, improving the flexibility and adaptability of the battery module assembly and testing system 10.

[0058] In one embodiment, the detection moving mechanism 620 includes a first detection moving component 621, a second detection moving component 622, and a third detection moving component 623. The first detection moving component 621 is connected to the detection mounting frame 610. The second detection moving component 622 is connected to the first detection moving component 621 and the third detection moving component 623 respectively. The detection camera 630 is connected to the third detection moving component 623. The first detection moving component 621, the second detection moving component 622, and the third detection moving component 623 are respectively used to drive the detection camera 630 to move along the X direction, the Y direction, and the Z direction.

[0059] The multi-level movement mechanism design, comprising a first detection movement component 621, a second detection movement component 622, and a third detection movement component 623, enables the detection camera 630 to achieve precise movement in three-dimensional space. The first detection movement component 621 moves the detection camera 630 along the X-direction, the second detection movement component 622 further moves the detection camera 630 along the Y-direction, and the third detection movement component 623 moves the detection camera 630 along the Z-direction. This multi-level movement structure ensures that the detection camera 630 achieves precise detection from all directions and angles in three-dimensional space, improving the comprehensiveness and accuracy of the detection. Simultaneously, this design allows the detection camera 630 to flexibly adapt to battery modules 20 of different sizes and shapes, enhancing the versatility and applicability of the detection system. Furthermore, through the cooperation of multi-level moving components, the position and attitude of the inspection camera 630 can be adjusted more precisely, effectively avoiding blind spots caused by movement in one direction, improving inspection accuracy and efficiency, and reducing the defect rate and scrap rate caused by positional errors. This effectively improves the inspection accuracy of the inspection device 600 for the battery module 20, and also enables the inspection device 600 to be applied to the inspection of battery modules 20 of different specifications.

[0060] Specifically, the first detection moving component 621 includes a first linear drive 6211 and a first moving frame 6212. The first linear drive 6211 is connected to the detection mounting frame 610 and the first moving frame 6212 respectively. The second detection moving component 622 includes a second linear drive 6221 and a second moving frame 6222. The second linear drive 6221 is connected to the first moving frame 6212 and the second moving frame 6222 respectively. The third detection moving component 623 includes a third linear drive 6231 and a third moving frame 6232. The third linear drive 6231 is connected to the third moving frame 6232 and the second moving frame 6222 respectively. The detection camera 630 is connected to the third moving frame 6232.

[0061] In this embodiment, the cooperation between the first linear drive 6211 and the first moving frame 6212 of the first detection moving component 621 ensures smooth movement of the camera in the X direction, enabling a larger detection range and reducing missed detections during the detection process. Secondly, the connection between the second linear drive 6221 and the second moving frame 6222 of the second detection moving component 622 allows the detection camera 630 to move quickly and accurately in the Y direction, adapting to battery modules 20 of different shapes and sizes, thereby improving the versatility of the detection device 600. The combination of the third linear drive 6231 and the third moving frame 6232 of the third detection moving component 623 makes the height adjustment of the camera in the Z direction flexible and convenient, thereby optimizing the shooting angle and maximizing the acquisition of image information of the object being detected. In summary, this detection moving mechanism achieves efficient and comprehensive detection capabilities through a multi-layered linear drive system, not only improving detection accuracy and reducing errors caused by manual operation, but also significantly improving overall work efficiency, providing reliable technical support for the quality management of the battery module 20.

[0062] In one embodiment, the first linear drive 6211, the second linear drive 6221, and the third linear drive 6231 can be a linear motor module or an electric actuator, and are not limited to any one of them.
