Technical vision system for detecting and marking defects on a plastic sheet

The project’s objective is introducing a vision system for detecting and marking defects, which is able to continuously monitor the presence of different-coloured inclusions, debris and stripes from incomplete inter-run penetration on a plastic sheet.

• Controlling the presence of different-coloured inclusions more than 1 mm on the sheet produced;
• Controlling the presence of debris more than 1 mm on the sheet produced;
• Controlling the presence of inclusions resulting from incomplete inter-run penetration of more than 1 mm on the sheet produced;
• Applying sticker marking on the product’s defective area;
• Work process light signaling.

1. Preparing technical specifications;
2. Determining the system’s main components;
3. System production;
4. Delivery to the place of installation;
5. Installation, testing. Putting the system into operation. Commissioning works are being carried out in order to set up the interaction of electrical equipment systems in various modes.

• Vision cameras and a printer-applicator are installed in the plastic sheet inspection zone;
• When the vision system detects a defect, a signal is sent to the printer-applicator;
• The printer-applicator applies a label to the defective area;
• All information about the defect cases number is stored in the system.
