Counting process and device for planar substrates

摘要

The process comprises the steps of: (a) loosening a pack of piled substrates; (b) taking a first image of the piled planar substrates, said image being made of a two-dimensional array of single image detectors arranged in lines and columns; (c) counting the number of edges of substrates detected; (d) statistically treating the result obtained from step (c); (e) based on the statistical treatment, determining whether the counting is accurate.
