Color defects inspection with Isra Vision
Reliably identifying all coating defects Color homogeneity control using full-area inline inspection in float glass production Coating defects such as color inconsistencies can considerably reduce the quality of products, so reliable identification of such defects is of utmost importance. The fully-automatic FLOATSCAN Color system inspects the coating quality directly in the production line and detects all serial defects at an early stage – before they become relevant and lead to defective material being processed further. Defects such as color inconsistencies can occur during the pyrolytic coating of glass ribbons in the line. In order to prevent defective material being processed such coating defects need to be taken into account when the panes are cut. In many cases, such defects are caused by errors in the coating process. To meet these challenges, ISRA offers fully-automated solutions that ensure full-area inspection for color defects. FLOATSCAN Color reliably detects all defects such as colored zebra striping, color lines and spots on the entire glass pane. It can both be used as a standalone system and integrated with the all-in-one FLOATSCAN 5D solution. Color inspection is implemented by means of a color camera and ISRA’s Frame Grabber solution, which has proven successful in many applications. Color defects are automatically identified at a very early production stage, avoiding the need for manual inspection processes.
enables users to control and optimize the process in real time and to take appropriate countermeasures in due time in the case of serial defects. Maintenance activities of the coating line can be planned better and the quality data obtained can be used to optimize production processes in a targeted manner. Quality data on the coating is used to accurately determine the quality of the goods produced, to ensure that products fully meet the customers’ expectations and to eliminate the risk of complaints.
