The chemical and pharmaceutical sectors are big users of automatic ampoule inspection machines. Before releasing ampoules to the market, a highly advanced system called the Automated Ampoule Inspection Machine automatically tests them for contamination. After the successful filling of the ampoule by the filling machine, the ampoule will be inspected for different defects like sealing defects, glass particles, fibers, fill volume, and foreign particles. It can be altered to meet different medicinal needs. Together with other related characteristics, it has an autonomous vision system and a washing and drying system for ampoules. A sophisticated piece of machinery is the Automatic Ampoule Inspection Machine. This machine guarantees the greatest possible level of product quality.
Comparison Between Human & Automated Inspection
Machine | Humans |
Better sensitivity for some types of defects. | More flexible for new products and packages |
More repeatable process | Quicker response to new defect types |
Better efficiency, higher throughput | Cost-effective for small batches with slow rates |
Reduced ergonomic injury risk | Reference standard for all compendia |
Often higher false reject rate | – |
High initial cost (0.7 MM to 3.0 MM) | Low initial Cost |

Description of the Automatic Ampoule Inspection Machine
Use the machine vision principle to identify and inspect the visible foreign matters; the testing products is stopped and to be motionless from high-speed rotation; capture images continually by the industrial camera; detect and inspect whether the products are qualified or not via computer system analyzing and comparing; and automatic classify the qualified and unqualified products.
Applications of the Automatic Ampoule Inspection Machine
- This machine can be used to inspect the liquid level and visible foreign particulates which the grain diameter
- or length is no less than 50um (such as chips of glass, metal filings, fibers, etc.);
- Inspect the appearance of the ampoule tip or vial cap (such as burnt spots, and shape defects);
- The machine can detect 1~5ml ampoule and vials;
- The machine can be used for the inspection of white bottles and brown bottles, colorless transparent liquid, and color transparent liquid.

Working Principle of the Automatic Ampoule Inspection Machine
Feeding Device: Made by mesh belt, screw, and roller. Undetected products are transported to screw by mesh belt. The drive plate turns them into the roller. Use machine visual principle. Get the picture of the bottle from the imported industrial camera, and transfer the picture to the industrial computer. Foreign matter and disqualified products will be detected automatically.
Use machine visual principle. Transfer the light-protective picture to the industrial computer. The foreign matter will be detected automatically. Use the light radiation method to check the liquid level to separate the disqualified product. Separate the empty bottle with accuracy.
Light Radiation Method Use optical imaging to check the drawing defect and carbonization. Use all servo light sources and cameras to track the ampoule or vial system. Stable running and onsite picture.
The Machine has a high frame rate visual camera. 60 frames per second. Low loss ratio. Use LED light source control technology to extend service life.
Servo controls bottle circling. High circling accuracy, convenient and accurate speed adjustment, and stable picture. Equipped with online circling speed monitor function.
Equipped automatically adjust system on the bottle circling break point. Accurate control of the brake point for different size bottles. Improve the detection accuracy.
The bottle press system is easy and fasts to adjust without a tool. The separation device has a bottle separator and servo motor. The bottle separator has front and back channels. One channel is for qualified products. When meets unqualified products, the computer will control the servo to control the separator. Unqualified products will be turned into another channel. Has HP’s large high-speed graphics computer. Fast speed and high detection resolution. Equipped with real-time fault monitoring alarm. Offer the fault point on time. Have remote technical support and diagnosis. It is suitable for 1-20 ml. Easy for assembling and disassembling.
