Integrated quality monitoring view for battery manufacturing process

A method of inferring quality of a sheet roll, the method comprising:

• monitoring surface defects of the sheet roll using at least one imaging device configured to capture surface images of the sheet roll;
• monitoring measurement defects of the sheet roll using a vision measurement system comprising at least one scanner configured to measure at least a basis weight and a thickness of the sheet roll;
• and
• monitoring quality and defect data of the sheet roll using a quality control system comprising a processor configured to analyze data received from the at least one imaging device and the at least one scanner;
• applying, by a marker device, fiducial markers on the sheet roll at predefined intervals along a machine direction, wherein the fiducial markers synchronize a defect measurement using data from the at least one imaging device, the vision measurement system and the quality control system;
• and
• generating, by the processor, a defect map that visually represents and correlates a defect data obtained from the at least one imaging device, at least one scanner, and the quality control system.
