  • Fully self-developed system with multiple patented designs and independent intellectual property rights
Working Principle

The automatic prefilled syringe inspection machine uses advanced machine vision to inspect visible foreign particles and appearance defects.

  • Foreign particle detection: As the syringe rotates at high speed, it is rapidly braked, while the liquid inside continues moving due to inertia. During this motion, the visual system captures multiple images and analyzes them to determine if any particles such as glass fragments or fibers are present.
  • Appearance inspection: The syringe rotates slowly more than 360°, allowing the vision system to capture images from all angles. These images are analyzed to detect issues such as stopper deformation or cap defects, ensuring a full-surface inspection.

Can the visual inspection system reliably detect tiny foreign objects such as glass fragments and rubber particles inside prefilled syringes?

Yes, the automatic prefilled syringe inspection machine is capable of detecting tiny foreign bodies inside prefilled syringes, including glass fragments and rubber particles.

What are the main features of the automatic prefilled syringe inspection machine?

The automatic prefilled syringe inspection machine adopts servo transmission for stable, compact, and safe operation. It allows fast and easy format change, features ultra high-speed and high-resolution industrial cameras for precise detection, and supports 360-degree full inspection. All key components such as electrical parts and bearings are sourced from top domestic and international brands. The system is fully self-developed and integrates multiple patented technologies, ensuring complete proprietary intellectual property.

Why is machine vision inspection important for prefilled syringe inspection in the medical field?

Because the drug inside prefilled syringes can pose contamination risks, any visible foreign particles are considered critical defects. If such issues go undetected, they could result in costly product recalls and pose serious risks to end users. The automatic prefilled syringe inspection machine helps pharmaceutical manufacturers prevent such risks by ensuring reliable defect detection.

Does the automatic prefilled syringe inspection machine support 360-degree visual inspection to detect complete surface defects?

Yes, the automatic prefilled syringe inspection machine performs 360-degree visual inspection of plastic syringes to ensure complete quality assurance.

Vacuum Decay
Vacuum Decay Vacuum decay leak detection is a non-destructive method used to verify the integrity of sealed packaging. The core principle involves detecting pressure changes in a vacuum environment to identify potential leaks.
High Voltage Leak Detection (HVLD)
High Voltage Leak Detection (HVLD) The system applies a high-frequency, high-voltage power source (denoted as V in the diagram), connected to both the emitter and receiver electrodes.
