In recent years, the new energy vehicle market has developed rapidly in China. As the core component of the power system, batteries require higher manufacturing precision and assembly accuracy. Battery tray welding is a critical step in battery manufacturing, directly affecting vehicle safety and driving range. Traditional welding methods face many challenges in achieving high-efficiency automation and precise positioning. So, how can advanced vision tracking technology enable real-time monitoring and dynamic adjustments during the welding process? Let’s explore this with Weld Navigator.
Introduction to Vision Tracking Systems
The weld seam vision tracking system integrates high-precision cameras, laser sensors, and intelligent image processing algorithms to capture real-time weld seam images. It automatically identifies weld dimensions, groove details, and dynamic variations. By utilizing laser triangulation and deep learning algorithms, the system precisely locates the weld seam and corrects deviations in real-time. This ensures that welding robots follow the correct trajectory. Vision tracking technology not only enhances welding accuracy but also significantly reduces errors caused by environmental interferences, such as arc light and thermal deformation, ensuring consistent weld quality.
Challenges in New Energy Battery Tray Welding
During the automated welding of battery trays, several challenges arise:
-
Lightweight Design: Battery trays often use lightweight materials like aluminum alloys, which have high thermal conductivity and are prone to thermal deformation, leading to weld misalignment.
-
