The SQD01 Scanner performs real-time quality control on the glass by detecting defects, indentations or microfractures, and displaying them on the monitor. A combination of innovative software and technology allows this scanner to detect accurate information as the glass is moving along the insulated glass production line conveyor or on a glass processing line conveyor. The scanner can be installed vertically and horizontally; the data collected is displayed within the normal working cycle times. The scanner has dedicated software that produces images with a resolution of up to 400 dpi (0.0635 mm). The defects detected by the scanner can be categorised by the user according to the type and size of defect. The scanned results are displayed on-line in real time and can alert the operator with preselected colours and standards, to automatically display an “accept” or “reject” status. These scans can also be stored for future reference and/or analysis using special data compression methods.
