Engineering Evaluation: Dual-Camera Inspection Architecture for Maximum Packaging Integrity
11/01/2026
Engineering Note: This technical documentation was originally published in 2019. It has been comprehensively updated on November 1, 2026, to reflect the latest advancements in JORNEN’s dual-camera vision inspection architecture and modern GMP compliance standards.
In the highly regulated pharmaceutical industry, stringent quality assurance of packaged solid dosage forms is critical to prevent costly manufacturer recalls and ensure absolute patient safety. To strive for zero-defect production, high-end Blister Packaging Lines are equipped with a comprehensive dual-camera inspection architecture, ensuring verification both before and after the sealing process.
1. Pre-Sealing Inspection (Product Integrity)
Positioned immediately downstream of the feeding station, the primary vision system inspects the open cavities prior to lidding foil application. This system utilizes high-speed image processing to detect missing products (empty pockets), broken or chipped tablets, and deviations in product color or geometric size.
Even with flawless product feeding, mechanical or alignment deviations can manifest during subsequent thermal and cutting processes. A secondary inspection system is employed later in the line to detect critical packaging defects, including:
Sealing Defects: Thermal wrinkles, unclear sealing grids (knurling patterns in rotary sealing) or dots (in platen sealing), and crushed solid doses trapped in the seal due to web misalignment.
Contamination: The presence of foreign objects (e.g., hair or particulates) trapped between the lidding and forming materials.
Mechanical & Print Defects: Missing, illegible, or incorrectly positioned embossed batch numbers, as well as punching misalignment (inaccurate cutting registration).
By identifying and automatically rejecting these faulty blister cards via an end-of-line rejection mechanism, this dual-inspection architecture guarantees maximum GMP compliance. The engineering video below demonstrates this dual-camera system operating in synchronization with the packaging workflow.
