Repeatable end-of-line inspection for automotive light guides

Controlar’s Light Guide Validation Cell is a semiautomatic end-of-line solution for inspecting light guides used in vehicle interior and exterior lighting. It integrates optical testing in a controlled dark chamber, machine vision inspection of connectors and pins, robotic handling and laser marking.

By combining manual loading with automated validation and OK/NOK classification, it supports repeatable quality control and individual component traceability.

  • Controlled measurement of light intensity, uniformity and color.
  • Automated handling and OK/NOK classification.
  • Permanent laser identification for component traceability.
  • Flexible configuration for different product variants.

From optical checks to individual traceability

The operator loads a light guide into a dedicated fixture. A dark chamber provides stable conditions for optical testing.

Parts that fail optical validation return to the operator. Passing parts move robotically to vision inspection, which checks connector and pin geometry and assembly.

Laser marking provides permanent identification. The cell then directs conforming and rejected parts to separate outputs.
