Overview

The glass online inspection system can detect defects in real-time during production and provide product quality information. It records quality data to optimize production processes. The system performs non-contact edge defect detection, surface flaw inspection, and dimensional measurement for products of varying widths and machine speeds.

Using a linear image sensor, the vision system scans targets in real-time to form images. Specialized image processing and analysis software based on an industrial control computer automatically detects surface defects, measures dimensions, and logs defect data into a categorized database. The system features a user-friendly Windows-based graphical interface.

Highlights

-- Recipe Management

The software allows customized parameter settings for each product type, saved as a “recipe.” During production, simply selecting the recipe automatically loads the corresponding parameters.

-- Classification

Defects are accurately classified using AI-based analysis of captured images, enabling customized criteria for different defect types.

-- Defect Recording (Database Functionality)

Defect characteristics and image data are stored in database files for offline queries, reporting, and printing.

-- Real-Time Interface Display

Instantly shows detected defect images, characteristic data, and trend charts.

Defects Classification (Top/Bottom Surfaces & Internal)

-- Surface Defects

Bubbles, stone inclusions, tin spots, dirt, scratches, glass fragments, water stains, color stains.

-- Edge Defects

Chipped edges, missing corners, cracks.

-- Grinding Defects

Unground areas, insufficient grinding, over-grinding.

-- Hole Defects

Hole diameter deviations, missing holes, hole edge cracks, chipped hole edges.

-- Side Defects

Burnt edges, glossy edges, fragmented edges.
