The Blister Tablet Packaging Defect Detection System uses visual inspection technology to detect defects on the appearance of tablets, capsules, and their aluminum foil packaging, automatically rejecting defective blister packs. Compared to traditional manual inspection methods, visual inspection offers higher efficiency and greater accuracy. The maximum detection precision can reach 50 microns. The inspection includes voids, half-pills, PVC foreign objects, color discrepancies on tablets, liquid leakage in capsules, missing batch numbers, etc.
