Glass Inspection for the Automotive Industry
Accurate glass defect inspection helps ensure the structural integrity of windshields, guarantee visual acuity, and add to the safety of automobiles on different terrains.
With years of experience delivering solutions for manufacturers in the automotive and other industries, KEYENCE offers a wide range of vision system products built for different glass inspection applications.
Vision Systems for Glass Inspection
Windshields must be able to withstand stress and impact from sources like temperature fluctuations and potholes. These considerations mean every cut must be of the appropriate thickness and flatness. Foreign objects or impurities getting trapped in a glass or tiny defects on its surface or structure could also cause structural issues. Intuitive vision systems make inspections for defects and deviations from production standards easy.
Line Scan Cameras
The KEYENCE Line Scan Series incorporates high-resolution line scan cameras, LumiTraxTM LED lighting, and other robust features to deliver accurate glass defect inspection results on scratches, dirt, dents, and more.
Inline 3D Inspection
Inline 3D inspection solutions help even production lines moving at high speed detect all defects with precision, ensuring glass with scratches, cracks, and other deformities are discovered before reaching the final assembly line.
AI Vision Systems
Leverage AI vision systems to achieve real-time, precise defect detection and continuous defect detection capabilities. Ensure only flawless windshields and glass get to the next stage of production.
Challenges in Glass Defect Inspection
Visibility
Lighting conditions and viewing angles can make a defect less visible to an inspection system. LumiTraxTM multi-angle illumination, high-dynamic-range (HDR) imaging, and other built-in features help reduce shadows, improve contrast, and highlight defects.
Defect Complexity
Vision systems setups struggle to detect and classify severe defects. AI-powered vision systems with advanced learning algorithms, high-resolution imaging, and 3D image processing units help detect defects, including bubbles, scratches, cracks, and contaminants.
False Positives and Negatives
Missed or misclassified defects cause waste. Glass inspection vision systems offer high-resolution detail capture, deliver controlled lighting, and utilize powerful image processing algorithms, ensuring defects detected are nothing else but defects.
Performance Issues
Mechanical vibrations, humidity, and lighting conditions can create performance issues. Vision systems for automotive manufacturing boast robust hardware, protective enclosures, advanced image processing algorithms, and more to compensate for threats to performance.
