en.Wedoany.com Reported - The German measurement technology company Micro-Epsilon has announced the launch of its new robot-based automated measurement system – Surface Control Automotive. This system is specifically designed for the fully automated surface inspection of Car Bodies in White (BiW) in automotive manufacturing. By integrating advanced fringe projection technology with machine learning algorithms, it aims to replace traditional manual visual inspections, significantly improving the efficiency of standardized inspection in mass production.
The Surface Control Automotive system utilizes 3D sensors based on the fringe projection principle to capture diffuse surfaces, enabling the detection of localized shape defects such as dents, bulges, indentations, or scratches on the car body in white with extremely high accuracy and repeatability. According to official data from Micro-Epsilon, the system achieves an area coverage of ≥97% in mass production, including complex areas such as door handle recesses, design edges, and highly curved surfaces. Due to its high defect detection rate, defect-free car bodies in white can be transferred directly to the painting process, bypassing manual quality inspection.
To ensure safety and flexibility in the industrial process, this automated measurement system is equipped with CAD-based simulation software for quickly defining measurement positions and robot movement paths. Simultaneously, the integrated 6D offset correction function effectively compensates for positional deviations of the car body. Its powerful software platform not only generates a digital master model from datasets of defect-free reference components but also supports analysis modes such as "digital sanding stone" and "digital light tunnel." Based on real 3D data evaluation, each defect can be assigned 3D characteristics such as diameter, area, and height, and classified and stored according to users' personalized requirements.
Micro-Epsilon states that all inspection results generated by this automated measurement system support export in XML format and can be seamlessly integrated into existing quality assurance systems. By combining with the Reflect Control Automotive system in the painting process, this solution provides a continuous, closed-loop automated inspection concept for the entire automotive body process, from car body in white manufacturing to final painting, enabling manufacturers to achieve more efficient production management and quality control.
