INSPECTION OF SEALING QUALITY IN BLISTER PACKAGES

摘要

An inspection system to inspect the consistency and thermal seal quality of blister packs comprising an illumination module; a color imaging device suitably integrated with an optical module; The blister packs that are thermally sealed are sequentially presented to the color imaging device within its Field of View; the inspection captures multiple images of the illuminated top side of the sealed blister package using the said image pickup device; analyzing the image and determining the gray scale values of the sealing area; comparing the gray level values with predetermined gray level values that are programmed at setup; making a decision to reject the inspected item if the analyzed gray level values is not substantially the same as the predetermined gray level values; making a decision to accept the inspected item if the analyzed gray level values is substantially the same as the predetermined gray level values or rejecting the blister if determined otherwise.
