In the glass manufacturing sector, the demand for impeccable quality and fully traceable processes is essential, as even the smallest imperfection can compromise the entire production workflow.
To meet these needs, Cugher, drawing on its decades of experience in horizontal vision systems, has developed a vertical quality control solution, GQVS VERTICAL, designed to deliver complete inspection and maximum visibility of the surface under analysis.
GQVS VERTICAL — The New Standard in Glass Inspection
Installed directly downstream of the washing machine, the system scans the entire glass sheet during vertical handling processes, ensuring extremely stable acquisition and high sensitivity to micro-defects thanks to customized illumination and high-resolution line-scan cameras.
GQVS VERTICAL can detect in real time:
- Scratches and micro-cracks
- Air bubbles, inclusions, stones
- Chips and contaminations
- Water drops or wet edges
- Over-polishing or edge defects
Why Integrate GQVS VERTICAL into Your Production Line
Adopting this system provides several operational advantages, including:
- Highly repeatable scanning on sheets of any length
- Defect detection free from reflection-related issues
- Stable acquisition even at high line speeds
- Completely uniform field of view on transparent surfaces
- Improved overall process management
The result is a continuous, precise, and fully autonomous inspection ecosystem designed to transform glass quality into a measurable, controlled, and optimized process.
Key Features
- Detection limits: scratches down to 0.06 × 0.25 mm; bubbles/chips down to 0.13 mm Ø
