The Westlin bottle is mainly used for packaging freeze-dried powder injections, vaccines, oral liquids, etc. The bottle body is thick and has a rubber stopper and an aluminum cap. The detection of powder impurities and appearance defects inside the bottle is very difficult. The dedicated dual-station visua inspection machine for Westlin bottles optimizes the dual-station inspection logic based on the characteristics of powder injections, solves the detection problems, and has become the core equipment of the powder injection production line of pharmaceutical enterprises. This article analyzes its technical highlights and application advantages.
The core pain points in the detection of Westlin bottles: The uneven thickness of the bottle body causes strong reflection, making it difficult for ordinary light sources to penetrate and form an image; The powder and impurities inside the freeze-dried powder injection bottles are easily confused, making identification very difficult; The glue plugs and aluminum caps are prone to generating debris, which is difficult to be detected when they fall into the bottle; The sealing of the bottle mouth and the cracks of the bottle body need to be detected simultaneously. A single workstation equipment cannot cover all these aspects, while a dedicated dual-workstation model precisely solves these problems.
The double-station visua inspection machine for Westlin bottles adopts a divisional inspection design. It is dedicated to the inspection of powder impurities. It is equipped with high-transparency LED light sources and polarizing lenses to eliminate bottle reflections and powder interference. Through AI algorithms, it can distinguish between normal powder and impurities, as well as lumps, solving the problems in powder injection agent inspection. The second station is the appearance inspection station, responsible for screening defects such as missing rubber stoppers, loose aluminum caps, bottle cracks, and liquid level deviations. The two stations work simultaneously to cover all inspection requirements.
The equipment operation process is in line with the production line for vials: The feeding mechanism evenly distributes the vials, avoiding damage caused by the collision of the rubber caps; Two working positions flexibly hold and fix the vial body, synchronously rotating the vial to disperse the powder impurities; Two sets of industrial cameras capture images in real time, and the main control system quickly determines; Unqualified products are automatically removed, and qualified products are smoothly discharged. The detection speed can reach 300-400 bottles per minute, with an accuracy of 20 μm, fully meeting the requirements of GMP certification.
For the production of powder injections and vaccines, the equipment is designed with a sterile level standard. The body is easy to clean and has no hidden sanitary areas, suitable for a hundred-level clean workshop. The software features comprehensive data traceability, permission management, and fault alarm functions. The entire testing process is traceable, meeting the requirements for controllable drug production throughout the entire process. At the same time, the equipment supports linkage with filling and packaging lines to achieve full-process automation.
Compared with ordinary light inspection machines, the double-station light inspection machine for vials is specifically designed to address the pain points in the detection of powder injections. It doubles the efficiency while maintaining the same level of accuracy, and its cost performance far exceeds that of multi-station equipment. It is the preferred inspection equipment for powder injection production lines of small and medium-sized pharmaceutical enterprises.The Westlin bottle is mainly used for packaging freeze-dried powder injections, vaccines, oral liquids, etc. The bottle body is thick and has a rubber stopper and an aluminum cap.
