Summary
Summary
ORAFOL Fresnel Optics implemented Zebra AI machine vision to automate the inspection of its Fresnel lenses, reducing inspection time by half. The solution involved a bespoke optical turret designed for the complex microstructures of the lenses, allowing for enhanced efficiency and consistency in quality control. As a result, the company improved its operational capacity and maintained high-quality standards across its product range.
Background
ORAFOL Fresnel Optics is a division of the ORAFOL Group, based in Germany. The company supplies over 600 components to global customers in various markets, including machine vision, sensor, lighting, display, and solar. Prior to the deployment of the AI machine vision system, ORAFOL relied on manual inspection methods, where operators examined each lens for defects under specific lighting conditions. This process was labor-intensive and required up to 15 operators to support production lines.
Challenge
The primary challenge ORAFOL faced was the need to automate the inspection of its complex Fresnel lenses, which can be as small as 4mm across. The existing manual inspection process was not only time-consuming but also prone to human error, leading to inconsistencies in quality assurance. ORAFOL sought a solution that could handle the intricate microstructures of their lenses while ensuring high-quality standards.
Solution
Zebra Technologies provided an AI machine vision system that utilized its Aurora software, compatible with any standard camera. A bespoke optical turret was developed specifically for the complex microstructures of the Fresnel lenses. This system enabled 24/7 workflows and end-to-end component traceability, allowing operators to focus on more strategic tasks rather than repetitive inspections.
Results
The implementation of Zebra's AI machine vision system resulted in a 50% reduction in lens inspection time. The system has processed over 1.5 million optical lenses, significantly enhancing operational efficiency. Additionally, the automation allowed for continuous quality assurance and improved consistency in defect detection, as the system applies written tolerances uniformly across all inspected parts.
Key Insights
One key takeaway from ORAFOL's experience is the importance of separating the costs of fixture and lighting engineering from software and camera hardware when planning vision inspection systems for small or microstructured parts. The complexity of the part design often necessitates custom solutions that can significantly impact the overall effectiveness of the inspection process.
Customer Testimonial
Rico Traxdorf, Production and Technology Lead at ORAFOL Fresnel Optics, stated, "Consistency was the biggest gain. The team writes a specification into the system, and any scratch outside it is rejected."
