Abstract

This quality defect diagnostic device comprises: a data division unit for dividing product data to be diagnosed in a two-dimensional manner into prescribed blocks; a data aggregation unit for extracting operation data and facility maintenance data for each pre-established classification of quality defects on the basis of the tendency of occurrence of quality defects in the post-division blocks, and aggregating the extracted operation data and facility maintenance data for each region including two or more blocks in a specific direction of the product; and a quality defect determination unit for determining whether a quality defect has occurred by using a plurality of prediction models that are created for each classification of quality defects and are trained on the relationship between quality data and the post-aggregation operation data and facility maintenance data.
