Double-station Visual inspection machine for ampoule bottles, efficient solution for injection drug testing

The ampoule bottle, as the core packaging of the injection, has a slender shape and precise sealing. Foreign objects and defects at the bottle mouth are the priorities for detection. The single-station visua inspection machine has low efficiency and incomplete detection. The multi-station equipment is too costly. The dedicated double-station visua inspection machine for ampoules specifically addresses the pain points and has become the detection solution for injection production enterprises. This article elaborates on the design highlights and application value of this dedicated equipment. 

The core difficulty in the inspection of ampoule bottles: The bottle body is slender and prone to reflecting light, and tiny impurities are easily obscured; The bottle mouth seal is thin and prone to dents, cracks and glass shards. Ordinary dual-station Visual inspection machines are difficult to adapt to these characteristics， while the specialized model for ampoule bottles has optimized the bottle type depth to achieve precise detection. 

The core design advantages of the double-station light inspection machine for ampoule bottles: Firstly, there is a dedicated flexible clamping mechanism that is suitable for ampoule bottles ranging from 1ml to 20ml. The clamping force is moderate, preventing the bottle body from being crushed and the bottle mouth from being damaged, thus avoiding contamination of the medicine by glass fragments. Secondly, there is a narrow-width dual optical system. The two stations respectively optimize the light source angle to eliminate the reflection of the bottle body, capture impurities inside the bottle, and the second station focuses on the sealing of the bottle mouth and the scratches on the bottle body, ensuring no blind spots in the detection. 

The third is the high-speed rotary bottle synchronization technology, with dual-station synchronous bottle braking. It optimizes the rotation speed for small-volume liquids, quickly generating vortices, allowing suspended impurities to be fully revealed, thus solving the problem of impurity detection in small bottle bodies. The fourth is the precise reject design, which, considering the small size of ampoule bottles, optimizes the reject device to avoid mistakenly rejecting qualified products and reduce material loss. 

In terms of performance, the double-station visual inspection machine for ampoule bottles can achieve a detection speed of 350-450 bottles per minute. One single machine can replace 8-10 human workers, and its efficiency is far superior to that of single-station models. The detection accuracy is 20 μm, fully meeting the standards of the injection drug pharmacopoeia, and the missed detection rate and false detection rate are much lower than those of humans. At the same time, the equipment adopts a stainless steel clean design and is equipped with a data traceability system, meeting the GMP compliance requirements of pharmaceutical enterprises. 

For injection drug manufacturers, the inspection of ampoule bottles is crucial for ensuring drug safety and corporate compliance. The dual-station light inspection machine for ampoules takes into account production capacity, accuracy and cost. It not only overcomes the drawbacks of manual inspection but also avoids the waste of production capacity caused by multi-station equipment. It is an ideal choice for mid-range injection production lines.
