Surface and edge inspection of float glass and coating lines for efficient process control

摘要

During the production process of glass, several incidences can happen causing defects within the glass material, like inclusions, stones, bubbles or blisters, or on the top or bottom surface, like roller marks, stains, streaks or scratches. Damages on the edges and corners of the substrate, like a breakage, crack or deformation, may also occur. The defects need to be detected and classified by the selected inspection system to find out if the glass sheet meets the quality requirement of the specification.
