The solution from K|Lens

Overview of solution approach and technical implementation

Conventional inspection methods reach their limits when testing coaxial connectors due to various challenges. Shiny surfaces, different material colors, complex geometries and the miniaturization of components make precise and reliable inspection difficult. Manual inspection is also time-consuming and prone to errors.

The pinOPTIX system provides the basis for an innovative solution to these challenges. By using state-of-the-art sensor technology, precise 3D analysis and robust AI-supported evaluation, it enables fast, accurate and comprehensive inspection of coaxial connectors. Automated inspection not only reduces time and error rates, but also improves product quality and reliability.

Specific design of the components / structure / extensions

Highly innovative sensor technology
Our Light Field Sensor HighRes with the highest resolution delivers precise image data. An additional polarization filter and highly diffuse light reduce reflections and also improve image quality.

3D analysis
Precise 3D analysis is made possible by special calibration and depth calculation components. These components ensure an accurate and measurable 3D reconstruction of the connector, which is essential for defect detection.

Robust evaluations with multiview AI
Customized data curation and multiview AI training provide a reliable multiview AI model for pin position detection. This AI-supported analysis enables precise and automated determination of measurement points.

Comprehensive evaluation
The merging of 3D data and AI analysis by evaluation algorithms enables automatic measurements according to customer specifications.

GUI
A customized graphical user interface (GUI) shows a digital twin of the connector and visualizes the pin positions detected by the AI as well as all specified measurements. This enables operators to check the inspection results intuitively and efficiently.
