This case study highlights the successful implementation of SEA Vision’s OCV Multipurpose and HarleTray inspection systems for a leading pharmaceutical manufacturer in the USA.

The project delivered a fully automated syringe packaging solution, improved product quality assurance, operational efficiency, and compliance with regulatory standards.

## **Challenges**

The pharmaceutical company faced several operational and compliance challenges:

- **Quality Control:** Verifying the correct presence, assembly, and orientation of all components in varying tray formats.
- **Regulatory Compliance:** Ensuring accurate label placement and data to meet international standards.
- **Operational Flexibility:** Supporting multiple packaging formats with rapid changeover and minimal downtime.
- **Data Visibility:** Providing transparent inspection results to operators and quality teams.

## **Solution**

To address these challenges, SEA Vision deployed a multi-stage vision inspection solution across four key machines in the packaging line:

### **1. Syringe Denester**

- **Nest Completeness and Syringe Count**  
  A camera inspects each nest to confirm all syringes are present before further processing. Incomplete nests are automatically rejected, ensuring only valid products continue down the line.

### **2. Syringe Detrayer**

- **Tray Orientation Check**  
  The vision system verifies the orientation of each tray. If incorrectly positioned, the system automatically rotates the tray 180° to ensure proper machine feeding.

### **3. Assembly and Labelling**

- **Plunger Rod presence: **
  
    - A color camera verifies the correct plunger rod is inserted.

-  
  
  **Stopper-Plunger Assembly: **
  
    - A backlight system checks the proper assembly of the stopper and plunger.

- **Label Presence and Position**
  
    - Post-labeling, another camera confirms the presence and correct positioning of the syringe label.

All non-compliant syringes are identified and automatically rejected.

### **4. Thermoforming**

Using HarleTray, three cameras inspect:

- **Component Presence in Tray: **The presence of all required tray components: syringe, vial, and two needles, also preventing mix-ups (for example, correct needle belongs to the correct syringe).

- **Tray Sealing Foil Code (Alucode): **The linear code printed on the sealing foil to verify alignment and correctness.
- **Heat Marker Label Presence: **The presence of the heat-sensitive marker label on each tray, which ensures traceable heat exposure over time.

## **Vision System Features**

- **OCV Multipurpose:** Enables multi-format inspections with fast and accurate defect detection.
- **HarleTray:** Specialized for thermoformed tray inspection with integrated lightbox and code reading capabilities.
- **OEM Interface Integration:** Allows seamless transition between machine and vision interfaces for enhanced control and visibility.

## **Results**

The implementation of SEA Vision’s inspection technologies delivered measurable benefits:

| **Outcome** | **Impact** |
| --- | --- |
| **Improved Quality Assurance** | 100% verification of critical components |
| **Operational Efficiency** | Automated rejections reduced downtime |
| **Format Flexibility** | Quick adaptation to multiple product formats |
| **Compliance & Traceability** | Complete visibility of inspection data |

**Conclusion**

This project represents a significant step forward in automating syringe packaging operations. The pharmaceutical manufacturer successfully transitioned from semi-automated processes to a fully integrated vision inspection solution. The collaboration with SEA Vision resulted in a packaging line that ensures component integrity, precise labeling, and end-to-end inspection—all within a compliant and future-ready framework.

### **From Manual Checks to Fully Automated Inspection**

SEA Vision’s OCV Multipurpose and HarleTray systems now ensure product quality from the very first step of denesting to the final tray seal—transforming the line into a benchmark of modern pharmaceutical packaging.
