[0019] (III) Beneficial Effects
[0020] This utility model provides an integrated device for detecting and repairing poor solder joints in battery modules, which has the following beneficial effects:
[0021] (1) This integrated battery module solder joint detection and repair equipment, through the setting of a power-on board, power-on needles, image acquisition camera and infrared thermal imager, when the battery module is located below the power-on support, the lifting rod pushes the power-on board downward, so that the power-on needles are connected to the positive and negative terminals of the battery module. The power-on needles provide test voltage and current in the battery module through the positive and negative terminals. At the same time, the detection machine measures the resistance, current and voltage of the battery module through the power-on needles and determines whether there is a solder joint problem in the battery module. After being powered on, the battery module is transported to the area below the image acquisition camera and infrared thermal imager. At this time, the image acquisition camera... The system clearly captures detailed images of the battery module and converts the captured images into digital signals, which are then transmitted to the testing machine for image processing and analysis. Simultaneously, because the battery module generates heat at the poorly soldered areas after being powered on, the infrared thermal imager captures the temperature distribution on the surface of the battery module. The testing machine analyzes and processes the collected temperature data to generate temperature distribution images and information on the location of poorly soldered points. After the battery module is inspected, it is transported to the welding repair position. When a poorly soldered area is found, the welding arm drives the welding gun to repair the poorly soldered area. These three detection technologies complement each other, enabling comprehensive and accurate detection of poorly soldered areas in the battery module, thus improving the accuracy of the testing and repair equipment.

[0028] Please see Figure 1-4 This utility model provides a technical solution: an integrated device for detecting and repairing poor solder joints in battery components, including a conveyor frame 1. A power-conducting bracket 11 and a testing bracket 18 are connected to the top of the conveyor frame 1. A lifting rod 12 is installed on the top of the power-conducting bracket 11, and a power-conducting plate 13 is connected to the bottom of the lifting rod 12. A power-conducting needle 14 is connected to the bottom of the power-conducting plate 13. A testing machine 15 is connected to the front of the power-conducting bracket 11. A display screen 16 and operation buttons 17 are connected to one side of the testing machine 15. An image acquisition camera 19 and an infrared thermal imager 20 are installed on the top of the testing bracket 18. A mounting base 21 is connected to the back of the conveyor frame 1. A rotary motor 23 is installed inside the mounting base 21. A rotating arm 22 is connected to the drive end of the rotary motor 23, and an adjusting motor 24 is connected to the front of the rotating arm 22.
[0029] Furthermore, a support frame 2 is connected to the bottom of the conveyor frame 1, a motor frame 3 is connected to one side of the support frame 2, a protective cover 4 is installed on the top of the motor frame 3, and a conveyor motor 5 is installed inside the protective cover 4. The conveyor frame 1 provides support, making the equipment more stable, and the motor frame 3 and the protective cover 4 serve to install and protect the conveyor motor 5.
[0030] Furthermore, a drive wheel 6 is connected to the drive end of the conveyor motor 5, and a transmission belt 7 is movably connected to the outer side of the drive wheel 6. The conveyor motor 5 drives the transmission belt 7 to rotate through the drive wheel 6, and the transmission belt 7 drives the conveyor roller 8 to rotate through the transmission wheel 10.
[0031] Furthermore, a conveyor roller 8 is movably connected to the inner side of the conveyor frame 1, and a conveyor belt 9 is movably connected to the outer side of the conveyor roller 8. A drive wheel 10 is connected to one end of the conveyor roller 8, and the drive wheel 10 is movably connected to the drive belt 7. The drive belt 7 drives the conveyor roller 8 to rotate through the drive wheel 10, thereby causing the conveyor roller 8 to drive the conveyor belt 9 to rotate, thus conveying the battery assembly.
[0032] Furthermore, a welding arm 25 is connected to the drive end of the adjusting motor 24, and a welding gun 26 is mounted on one end of the welding arm 25. The welding arm 25 can be adjusted in all directions, allowing the welding gun 26 to weld different positions of the battery assembly.
[0033] Furthermore, two inspection brackets 18 are provided, both of identical shape and symmetrically arranged. The inspection brackets 18 facilitate the installation of the image acquisition camera 19 and the infrared thermal imager 20 by personnel to inspect the battery assembly.
[0034] Working Principle: After installation, the installation, fixation, and safety precautions of this utility model are first checked. When using the integrated battery component solder joint detection and repair equipment, when the battery component is on the conveyor belt 9, the conveyor motor 5 drives the transmission belt 7 through the drive wheel 6, and the transmission belt 7 drives the conveyor roller 8 through the transmission wheel 10. At this time, the conveyor belt 9 starts to move, thus conveying the battery component. When the battery component is below the power-conducting bracket 11, the lifting rod 12 pushes the power-conducting plate 13 downward, so that the power-conducting needle 14 connects with the positive and negative terminals of the battery component. The power-conducting needle 14 provides test voltage and current to the battery component through the positive and negative terminals. At the same time, the detection machine 15 measures the resistance, current, voltage, and other parameters of the battery component through the power-conducting needle 14 and determines whether there is a solder joint problem in the battery component. The battery assembly, after being powered on, is transported below the image acquisition camera 19 and the infrared thermal imager 20. At this time, the image acquisition camera 19 clearly captures detailed images of the battery assembly and converts the captured images into digital signals, which are then transmitted to the inspection machine 15 for image processing and analysis. Simultaneously, because the battery assembly generates heat at the poorly soldered areas after being powered on, the infrared thermal imager 20 captures the temperature distribution on the surface of the battery assembly. The inspection machine 15 analyzes and processes the collected temperature data to generate temperature distribution images and information on the location of the poorly soldered points. After the inspection is completed, the battery assembly is transported to the welding repair position. When a poorly soldered area is found, the welding arm 25 drives the welding gun 26 to weld and repair the poorly soldered area. This completes the usage process of this utility model. This utility model has a simple structure and is safe and convenient to use.
