Automated Bergstik Connector Inline Inspection System
Overview
In electronics manufacturing, connector assembly quality plays a decisive role in product reliability and long-term performance. Even the smallest misalignment of pins or mold orientation errors can cause failures in downstream applications. Traditionally, connector inspection relied on manual visual checks — methods prone to human error, inconsistency, and inefficiency.
To overcome these limitations, Unilogic Technologies engineered a fully automated Bergstik Connector Inline Inspection System. This Machine Vision Based Inspection Solution integrates multi-camera vision stations, precision illumination, and PLC-based automation to deliver 100% inline quality assurance before connectors reach packaging.
Process Overview
The system performs End-to-End Inspection of Bergstik connectors, from mold orientation verification to pin true position (TP) inspection, ensuring only defect-free connectors move forward.
1. Component Feeding
- Connector molds and golden pins are fed separately.
- Proper direction of pin insertion is verified to prevent assembly defects.
2. Mold Orientation Inspection (Vision Station 1)
- A 6 MP high-resolution camera with HPDG ring light illumination captures mold images.
- Custom vision algorithms detect mold orientation.
- Results are communicated to the PLC, which activates a rotary mechanism to correct mold position before pin insertion.
3. Pin Insertion & Assembly
- Once orientation is corrected, molds move to the Pin Insertion Station.
- Pins are inserted and formed into the final connector structure.
4. Pin True Position (TP) Inspection (Vision Stations 2, 3, and 4)
- Three 20 MP high-resolution cameras verify pin alignment with high accuracy:
- Top Camera: Checks golden pins for alignment and spacing.
- Front Camera: Validates silver bent pins from the front.
- Rear Camera: Inspects silver bent pins from the rear.
- Each vision station uses front-light illumination for precise feature detection.
- Independent results are relayed directly to the PLC.
5. Synchronization & Sorting
- The PLC aggregates inspection data from all stations.
- Pass/fail status is determined in real time.
- Defective connectors are automatically rejected, while good connectors move to packaging.
