Description

Technical Field

[0001] The present invention relates to the technical field of welding devices, in particular to welding equipment for a power circuit board of an electric vehicle. Background Art

[0002] Electric vehicle power circuit board soldering equipment is crucial in electric vehicle manufacturing, directly impacting the safety, reliability, and performance of the battery system. Power circuit boards incorporate multiple functional modules, including the battery management system, charging circuitry, and power conversion circuitry. Soldering technology ensures stable battery charging and discharging by ensuring secure connections between circuit board components. Common soldering methods include wave soldering, reflow soldering, and manual soldering. Wave soldering is suitable for high-volume production, while reflow soldering precisely controls temperature and is suitable for high-precision components. Laser soldering provides a high-precision solution for advanced battery management systems. Driven by smart manufacturing, automated soldering systems are becoming increasingly popular, improving production efficiency and soldering quality. In the future, power circuit board soldering equipment will further evolve towards intelligent and automated processes to meet the challenges of increasingly complex electric vehicle battery technology and rising performance requirements. Therefore, selecting the right soldering equipment and continuously optimizing its technology are crucial factors in driving the development of the electric vehicle industry.

[0003] For example, the Chinese patent with publication number "CN118237689A" discloses "A circuit board welding device", which includes a workbench, a placing table is provided at the top center of the workbench, the workbench is located at both ends of the placing table and is slidably connected to a first cylinder, the output end of the first cylinder is provided with a first motor, the output end of the first motor is provided with a mounting plate, the mounting plate is located at both ends of the first motor and is slidably connected to a U-shaped frame, a stop block is provided at the bottom of the U-shaped frame, a first electric telescopic rod is provided at the top of the U-shaped frame, a pressure block is provided at the output end of the first electric telescopic rod, and second electric telescopic rods are provided at both ends of the mounting plate, and the output end of the second electric telescopic rod is fixedly connected to the U-shaped frame. The present invention enables the circuit board to be flipped over in a clamped state through the design of the first motor, thereby improving the welding efficiency.

[0004] However, in actual use, the above-mentioned electric vehicle power circuit board welding equipment requires external equipment or manpower for loading and unloading. Manual or external equipment operation will significantly reduce production efficiency because this intermittent operation cannot match the working speed of the welding equipment, resulting in a longer production cycle. Secondly, manual operation is prone to errors, such as incorrect placement of circuit boards or damage to components, which affects welding quality and increases rework and scrap rates. Long-term reliance on manual loading and unloading may also cause operator fatigue, increase the risk of errors, and may have a negative impact on employee health. In addition, the use of manual or external equipment will reduce the actual utilization rate of the equipment and waste production time. Due to the inconsistency of the loading and unloading process, it is not conducive to standardized production and affects the consistency of welding results. Finally, this operation method also increases manpower and equipment maintenance costs. Summary of the Invention
