Product quality sorting inspection system self monitoring procedure for tiles and flat panels records time variation of deviation for error class and compares with set tolerance band

摘要

A product quality sorting inspection system self monitoring procedure records the time variation for an error class (2) of the instantaneous detected error frequency and product characteristic deviation (3) from the correct value and compares it with a set tolerance band using multiples of the value for a correctly set system. Independent claims are included for equipment implementing the procedure using a static module installed on a computer.
