Function and Principle of Light Inspection Machine

Application

The light inspection machine is suitable for inspection of oral liquids, powder injections, freeze-dried powder injections, biochemical preparation and other products in pharmaceutical industry, health product industry, biochemical industries, etc. It is mainly for inspection of vial bottles, ampoule bottles, cartridge bottles, syringes, oral liquids, and other freeze-dried products.

Detection Principle

The automatic light inspection machine uses industrial vision cameras and computer image analysis technology to detect foreign objects, defects, and omissions in products. At the same time, it uses high-speed cameras and intelligent lighting systems to capture and analyze high-speed dynamic images of the running product.

1. Sealing and Package Integrity Inspection

Upon entering the machine, each container is automatically inspected for the following key metrics:

(1) Container Contamination: Identifies stains, impurities, or any foreign matter adhering to the bottle surface.

(2) Sealing Performance: Detects low vacuum levels resulting from improper sealing or other factors. It adopts laser gas chromatography inspection which requires the vial to be filled under nitrogen or vacuum conditions.

(3) Package Integrity: Checks whether the bottle is capped without rubber stopper or plastic cap, etc. .

2.Foreign Matter Inspection

Capable of accurately identifying various types of insoluble foreign matter and dynamic/static impurities, including but not limited to:

(1) Solid contaminants such as glass fragments, fibers, and hair.

(2) Discolored particles like black spots, white spots, and colored spots.

(3) Impurities mixed in during the filling process and precipitated foreign matter in a static state.

3. Appearance Defect Inspection

Check whether there is a defect on the top of bottles and other critical areas, specifically:

Sealing Defects: Drawing, flat cap, oblique cap, carbonization, wrinkled aluminum seals, etc.

Container Defects: Structural flaws such as cracks or bulges.
