In the automotive industry, unique high temperature seals are used in hydrogen fuel cells to guarantee efficiency and safety. For optimal performance, these seals must be thoroughly inspected for dimensional accuracy and possible damage during production. Achieving precise and consistent results requires the use of high-resolution cameras paired with homogeneous illumination by bar lights. This setup ensures that any defects on the interior or exterior of the seals are reliably detected.
Diffuse illumination has been integrated in this application to generate intense brightness and homogeneous lighting. Installed as part of the machine vision system, the two BLABAR bar light offers flexibility and customisation. This is ideal for the task as it can be adjusted to various angles and distances without compromising performance.
Challenges
- Environmental conditions – Changes in ambient lighting and other objects in the workspace can potentially compromise the inspection process.
- Speed vs accuracy – High-speed production can impact the quality of the images captured which may result in missing small defects in the seals.
- Complex angles and working distances – The compact setup of these systems causes uneven reflections and shadows.
Solution
- Uniform lighting – The positioning of the two BLABARs provides perfect illumination for minimising shadows and highlights in dynamic environments. This ensures accuracy and reliability.
- High-speed and High-brightness – Designed for fast-paced environments, the bar light operates at a rapid rate, seamlessly integrating into high speed production lines without sacrificing illumination quality.
- Adaptability for all angles – This versatile lighting solution produces contrast and precision for high-quality images to guarantee that the smallest defects are clearly highlighted at any angle.
