Automated Inspection of Recycled Bottles (88)
Problem: Develop equipment for rapid, on-line inspection of recycled bottles to detect flaws and foreign contaminants
Project Activity Scope (from Technical Overview Chart): Interaction Mechanisms through Measurement & Analysis System Applications
PNNL Solution:
- Determined if optical fluorescence reliably detects contaminants in bottles
- Demonstrated optical scattering of bottle mouth detects chips and cracks
- Developed integrated bottle handler and inspection modules to demonstrate on-line inspection performance
- Completed successful system demo
Capabilities Employed to Meet Client Needs: Optical interactions with materials (e.g., fluorescence of organic materials including excitation wavelength effects and emission wavelength); optical scattering dependence on surface geometry and defect structure; optical system design; optical scanner systems using galvanometric mirrors; laser source design; imaging optical system design; mechanical handler design; signal processing electronics including decision making circuitry (accept/reject); mechanical handler control system; system documentation and reporting of results.
