Description

Technical Field

[0001] This utility model relates to the field of battery module production, and more specifically, to a multifunctional testing device. Background Technology

[0002] In the production and assembly of battery modules, inspecting the welding quality of the end faces, the cleanliness of the appearance, and the polarity of the terminals is a crucial step in ensuring product safety and reliability. Traditional inspection methods typically require setting up independent inspection stations and assigning dedicated personnel to transfer products to these stations for inspection before moving them to the next process. This not only increases the space occupied by the equipment but also extends the production cycle time and makes the operation cumbersome, making it difficult to meet the requirements of high-efficiency and highly automated modern production lines. Utility Model Content

[0003] The purpose of this invention is to provide a multifunctional testing device that can complete testing simultaneously during the transfer process, thereby simplifying the process and improving testing efficiency and automation.

[0004] A multifunctional testing device, comprising: A transfer mechanism for conveying a fixture loaded with battery modules to be tested, wherein a testing station is provided along the transfer path of the transfer mechanism; and The testing mechanism, suspended above the testing station, includes a robotic arm and an execution end. The robotic arm is used to drive the execution end to move within a preset range above the testing station. The execution end includes a mounting base, on which a visual inspection component and a barcode scanning component are provided. The visual inspection component is used to perform visual inspection on the battery module, and the barcode scanning component is used to scan the identification code of the battery module.

[0005] In the above technical solution, the testing mechanism is positioned above the testing station. When the battery module is transferred to this station, its end face welding points, cleanliness, and terminal polarity can be simultaneously tested, achieving integrated testing during the transfer process. This eliminates the need for a separate testing station, simplifying the testing process and improving production efficiency. Furthermore, the testing mechanism integrates visual inspection and barcode scanning functions into the actuator driven by the robotic arm, forming a compact and functionally integrated testing unit. This not only reduces equipment space requirements but also ensures the continuity and automation of the testing process.

[0006] Furthermore, the visual inspection component includes a camera and an illumination element, the illumination element having a through hole, and the camera being positioned above the through hole and facing the transfer mechanism.

[0007] In the above technical solution, by placing the camera above the through hole of the lighting component, the lighting source can be arranged around the camera, thereby providing a uniform and shadow-free lighting environment for the battery module below. This effectively avoids the impact of uneven light or external reflection on the image quality, thus ensuring the clarity and consistency of the visual inspection image.

[0008] Furthermore, a protective cover is provided around the camera.

[0009] In the above technical solution, the protective cover set on the outside of the camera can effectively prevent dust, oil or possible splashes on the production line from directly contacting the camera, thus enhancing the camera's service life.

[0010] Furthermore, the mounting base is also provided with a laser positioning component, which is arranged adjacent to the vision inspection component.

[0011] In the above technical solution, a laser positioning component is set on the mounting base near the vision inspection component, so that the execution end can quickly determine the precise position and height of the battery module by laser ranging before using vision inspection, thereby providing accurate positioning for subsequent inspection and improving the overall inspection accuracy and efficiency.

[0012] Furthermore, the laser positioning component includes a laser sensor and an adjustment component, the adjustment component being used to adjust the position and angle of the laser sensor.

[0013] In the above technical solution, the setting of the adjustment component in the laser positioning component allows the detection height and angle of the laser sensor to be finely adjusted according to different battery module models, thereby enhancing the adaptability and flexibility of the laser positioning function.

[0014] Furthermore, the fixture includes a base that is slidably connected to the transfer mechanism, and the base is provided with a positioning component for fixing the battery module.

[0015] In the above technical solution, the fixture is slidably connected to the base of the transfer mechanism and integrates positioning components, so that the battery module can be quickly fixed by the positioning structure on the base and can be stably moved to the inspection station with the fixture, ensuring the positional certainty and stability of the module throughout the entire transportation and inspection process.

[0016] Furthermore, the positioning component includes two positioning units, each of which includes a movable component and a fixed component disposed opposite to each other, the movable component being configured to slide toward or away from the fixed component.

[0017] In the above technical solution, the positioning component includes two positioning units, which can respectively position the two sets of opposite sides of the battery module. The movable component is slidable, and by sliding and adjusting the position of the movable component, stable and reliable clamping and centering of both ends of the module can be achieved, ensuring the accuracy and stability of the module's posture during testing.

[0018] Furthermore, the movable component includes a sliding seat slidably connected to the base, and the sliding seat is provided with at least one elastic clamping member.

[0019] In the above technical solution, when clamping the battery module, the elastic clamping component can absorb dimensional tolerances through its own deformation and continuously apply clamping force, which can effectively fix the module and prevent it from loosening. At the same time, it can avoid the squeezing damage to the module shell that may be caused by rigid clamping.

[0020] Furthermore, the base is provided with a check rack, and the sliding seat is provided with an elastic bolt, which can resist the check rack through elastic force.

[0021] In the above technical solution, a one-way locking mechanism is formed by the cooperation of the anti-return rack on the base and the elastic bolt on the sliding seat. This structure allows the sliding seat to move smoothly when sliding towards the fixed component to clamp the module, and can effectively prevent it from accidentally loosening in the reverse direction due to vibration or external force during the detection process, thereby ensuring the reliable maintenance of the clamping state and improving operational safety.

[0022] Furthermore, the transfer mechanism is provided with a stop component near the detection station to block the clamp.

[0023] In the above technical solution, a stop component is set near the inspection station of the transfer mechanism, which can block and position the fixture when it is transported to the predetermined position, ensuring that the battery module can be accurately stopped at the preset position below the inspection mechanism during each inspection, providing accurate positioning for subsequent inspections.

[0024] Compared with existing technologies, the advantages of this invention are as follows: The inspection mechanism is positioned above the inspection station. When the battery module is transferred to this station, the welding points, cleanliness, and terminal polarity of its end face can be simultaneously inspected, achieving integrated inspection during the transfer process. This eliminates the need for a separate inspection station, simplifying the inspection process and improving production efficiency. Furthermore, the inspection mechanism integrates visual inspection and barcode scanning functions into the actuator driven by the robotic arm, forming a compact and functionally integrated inspection unit. This not only reduces the space occupied by the equipment but also ensures the continuity and automation level of the inspection process. Attached Figure Description

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0034] Please refer to Figures 1 to 6In a preferred embodiment, the multifunctional testing equipment of this utility model mainly includes a transfer mechanism 1 and a testing mechanism 2. The transfer mechanism 1 is used to transport a fixture 3 loaded with a battery module to be tested, and a testing station 11 is provided along the transfer path of the transfer mechanism 1. The testing mechanism 2 is suspended above the testing station 11 and includes a robotic arm 21 and an execution end 22. The robotic arm 21 is used to drive the execution end 22 to move within a preset range above the testing station 11. The execution end 22 includes a mounting base 221, on which a vision inspection component 222 and a barcode scanning component 223 are provided. The vision inspection component 222 is used to perform visual inspection of the battery module, and the barcode scanning component 223 is used to scan the identification code of the battery module.

[0035] For example, the transfer mechanism 1 can use an existing conveying system, such as a high-speed chain conveyor, which includes two parallel guide rails. The two ends of the clamp 3 are slidably connected to the corresponding guide rails, allowing the clamp 3 to be mounted between the two guide rails and slide along them. The inspection station 11 is located along the transfer path of the transfer mechanism 1, and the inspection mechanism 2 is suspended above the inspection station 11 by a bracket (not shown). The robotic arm 21 of the inspection mechanism 2 has a range of motion covering the clamp 3, enabling the actuator 22 to perform a comprehensive inspection of the upper surface of the battery module located on the clamp 3. The vision inspection component 222 is used to inspect the end face of the battery module by taking pictures, specifically checking for issues such as whether the solder joints are faulty, whether the surface is clean, and whether the polarity of the terminals is reversed. The barcode scanning component 223 can use an existing barcode scanning device to scan the identification code on the end face of the battery module, thus correlating the inspection data with the battery module for easy management and traceability.

[0036] As can be seen from the above technical solution, the inspection mechanism 2 is located above the inspection station 11. When the battery module is transferred to this station, the welding points, cleanliness, and polarity of its end face can be inspected simultaneously, realizing integrated inspection during the transfer process. This eliminates the need for a separate inspection station 11, simplifying the inspection process and improving production efficiency. Simultaneously, the inspection mechanism 2 integrates visual inspection and barcode scanning functions into the execution end 22 driven by the robotic arm 21, forming a compact and functionally integrated inspection unit. This not only reduces the space occupied by the equipment but also ensures the continuity and automation level of the inspection process.

[0037] Please refer to Figure 2 and Figure 3The visual inspection component 222 includes a camera 2221 and an illumination element 2222. The illumination element 2222 has a through-hole, and the camera 2221 is disposed above the through-hole and faces the transfer mechanism 1. For example, the illumination element 2222 is a ring-shaped LED light with a through-hole in the center. The camera 2221 is fixedly mounted above the illumination element 2222, with its lens facing the through-hole. By disposing the camera 2221 above the through-hole of the illumination element 2222, the illumination source can be arranged around the camera 2221, thereby providing a uniform and shadow-free lighting environment for the battery module below. This effectively avoids the impact of uneven light or external reflections on image quality, thus ensuring the clarity and consistency of the visual inspection image.

[0038] In this embodiment, a protective cover 2223 is provided around the camera 2221. The protective cover 2223 provided outside the camera 2221 can effectively prevent dust, oil stains or possible splashes on the production line from directly contacting the camera 2221, thereby enhancing the service life of the camera 2221.

[0039] The mounting base 221 is also equipped with a laser positioning component 224, which is arranged adjacent to the vision inspection component 222. By placing the laser positioning component 224 on the mounting base 221 adjacent to the vision inspection component 222, the execution end 22 can quickly determine the precise position and height of the battery module by laser ranging before using vision inspection, thereby providing accurate positioning for subsequent inspection and improving the overall inspection accuracy and efficiency.

[0040] Specifically, the laser positioning assembly 224 includes a laser sensor 2241 and an adjustment assembly 2242, which is used to adjust the position and angle of the laser sensor 2241. For example, an existing laser sensor 2241 can be used. The adjustment assembly 2242 includes a first shaft 2243, a second shaft 2244, and a connecting block 2245. The first shaft 2243 extends vertically, with one end connected to the mounting base 221 and the other end passing through the connecting block 2245. The second shaft 2244 extends horizontally, with one end connected to the connecting block 2245 and the other end connected to the laser sensor 2241. By rotating or sliding the first shaft 2243 and the second shaft 2244, the position and angle of the laser sensor 2241 can be finely adjusted, allowing the laser positioning assembly 224 to adapt to different detection requirements and enhancing the adaptability and flexibility of the laser positioning function.

[0041] Please refer to Figure 4 and Figure 5The fixture 3 includes a base 31, which is slidably connected to the transfer mechanism 1. The base 31 is provided with a positioning component 32 for fixing the battery module. The fixture 3 uses a base 31 that is slidably connected to the transfer mechanism 1 and integrates the positioning component 32, so that the battery module can be quickly fixed by the positioning structure on the base 31 and can be stably moved to the inspection station 11 with the fixture 3, ensuring the positional certainty and stability of the module throughout the entire transportation and inspection process.

[0042] The positioning component 32 includes two positioning units, each including a movable component 321 and a fixed component 322 arranged opposite to each other. The movable component 321 is configured to slide to move closer to or further away from the fixed component 322. The positioning component 32 includes two positioning units capable of positioning two sets of opposite sides of the battery module respectively. The movable component 321 is slidable, and by adjusting the position of the movable component 321, stable and reliable clamping and centering of both ends of the module can be achieved, ensuring the accuracy and stability of the module's posture during testing.

[0043] The active component 321 includes a sliding seat 3211 slidably connected to the base 31, and at least one elastic clamping member 3212 is provided on the sliding seat 3211. Exemplarily, the elastic clamping member 3212 includes a pressure block and a spring. The pressure block is configured to move linearly, and the spring is disposed between the pressure block and the sliding seat 3211. When clamping the battery module, the elastic clamping member 3212 can absorb dimensional tolerances through its own deformation and continuously apply clamping force, which can effectively fix the module and prevent it from loosening, while avoiding the squeezing damage to the module shell that may be caused by rigid clamping.

[0044] The base 31 is equipped with a check rack 311, and the sliding seat 3211 is equipped with an elastic bolt 3213. The elastic bolt 3213 can abut against the check rack 311 through elastic force. By cooperating with the check rack 311 on the base 31 and the elastic bolt 3213 on the sliding seat 3211, a one-way locking mechanism is formed. This structure allows the sliding seat 3211 to move smoothly when sliding towards the fixing component 322 to clamp the module, and can effectively prevent it from accidentally loosening in the opposite direction due to vibration or external force during the detection process, thereby ensuring the reliable maintenance of the clamping state and improving operational safety.

[0045] Please refer to Figure 6The transfer mechanism 1 is equipped with a stop assembly 12 near the inspection station 11 to block the clamp 3. Exemplarily, the stop assembly 12 includes a stop drive 121 and a stop block 122. The stop drive 121 is a cylinder, and its output end can push the stop block 122 to rotate, causing the stop block 122 to extend or retract from the transfer plane of the transfer mechanism 1. When the stop block 122 extends out of the transfer plane, it can prevent the clamp 3 from continuing to move. The stop assembly 12, located near the inspection station 11 of the transfer mechanism 1, can block and position the clamp 3 when it is transported to a predetermined position, ensuring that the battery module can accurately stop at a preset position below the inspection mechanism 2 during each inspection, providing accurate positioning for subsequent inspections.
