In the fast-paced world of automotive manufacturing, the polishing and grinding of vehicle body panels is critical to final appearance quality. Picture robotic arms in action—sparks flying—as they strive to create flawless, streamlined surfaces. Yet, this high-speed, high-pressure environment makes defect detection extremely challenging.
Traditional visual inspection methods, dependent on human eyes, often struggle to keep up with production speed, leading to fatigue, inconsistent standards, and missed fine flaws like micro scratches, shallow dents, or orange peel textures.These challenges create pain points for manufacturers: low detection efficiency, inconsistent quality, high costs from rework or customer complaints, and the risk of undetected flaws damaging brand reputation. With advancements in Edge AI, intelligent robotic solutions for defect detection and surface finishing are becoming the go-to choice for manufacturers. By combining machine vision with intelligent robotics, edge-based defect detection enables real-time analysis of visual data during production. The system automatically detects flaws and adjusts polishing force and paths, dramatically improving efficiency and consistency.
At the heart of this smart solution is Portwell’s PJAI-100 series embedded industrial computer, integrated with robotic arm controllers and machine vision components.
High-resolution cameras, mounted on robotic arms, capture real-time surface images via RJ45 and USB interfaces. These images are transmitted to the PJAI-100 system, which is equipped with the NVIDIA Jetson Orin module, delivering 100 TOPS of AI performance for real-time complex image recognition. The system identifies defects with precision beyond the human eye and sends control commands over EtherCAT/ Profinet to the robot controller. Motors and servo drivers execute exact polishing motions, guided by 3D vision and force sensors to ensure even force and perfect contours.
Built for industrial environments, the PJAI-100 features fanless operation, wide temperature tolerance (-20°C to 60°C), and a full range of I/O (USB 3.2, COM, CANbus), making it easy to integrate with other devices on the floor. The system supports real-time monitoring via teach pendants and HMIs, ensuring safe and accurate operation. Its edge AI capability reduces latency and stabilizes data processin
g, enabling a fully coordinated and automated production line.
