Technology licensing agreement
Problem addressed
Based on needs from the injection molding industry for product quality, FLAIR develops a fully automatic optical inspection device based on artificial intelligence, which solves the pain points of visual inspection in traditional industries that rely on manual labor and experience, realizing 100% visual quality inspection and visual defects information quantification.
Innovation
- By combining frontend including high-res camera, auto-focus lens and stepping motor rotary table, and backend with neural network based image processing algorithm, the device realizes 360° vision inspection of the product surface
- Users only need to place the product on the rotary table to start inspection. These actions can also be completed with a robotic arm, which has high flexibility
Key impact
- Replacing manual visual inspection to achieve 100% on-line or near-line visual quality inspection
- Achieving lower cost than industrial laser inspection
- Realizing digital quality management with quantified defect information
Application
- Vision inspection of ultra-sonic welded workpieces
- Vision inspection of injection molded workpieces

- PRC Utility Model Patent Application No. : 202222999357.8
The Hong Kong Industrial Artificial Intelligence & Robotics Centre (FLAIR) is established by the Hong Kong Productivity Council (HKPC) at the Hong Kong Science Park and is part of AIR@InnoHK, which is one of the two world-class research clusters being established by InnoHK Clusters of the HKSAR Government, to support Hong Kong in developing into an international innovation and technology hub.
FLAIR aims to engender synergy and achieve a clustering effect by attracting top-notch local, Mainland and overseas research institutions to engage in research collaboration. It will also actively approach private enterprises and industry associations for consultation and solicit their involvement in FLAIR’s work to ensure its industry orientation in addressing major R&D problems encountered by the industries in AI adoption.
As the sole founder, HKPC works together with RWTH Aachen Campus of Germany, the major collaborator of FLAIR, by bundling their strengths and repertoire of resources in technical expertise, networks, innovation and patents etc. to set up the FLAIR and support its operation.
