After checking that the product level and cap position are correct, the vision system will detect the closure status to verify the seal integrity, and it will also specifically verify the presence of the tamper-evident band and the security seal. The machine vision system can detect defects and confirm the integrity of the packaging through accurate and consistent detection. The 3D laser displacement sensor ensures that the security seal covers the entire opening, there are no bubbles or wrinkles around the edge of the lid, and there are no holes or perforations. Machine vision technology can detect the edges of the security seal and measure its height, width, relative position and gap size (if any), and compare it with the pre-defined limits. Tamper-evident seals that do not meet the pre-defined limits will be rejected to reduce the risk of product recalls.
