Bubble detection included in transparent plastic material

Case study

Defect control: detection of small bubbles in transparent plastic parts in a continuous high speed process.

Objectives

• Detection, measurement and classification of bubbles by size thresholding: diameter from 0.3 to 4 mm.
• Alert production operators of an anomaly in the farication process.
• Move from sample-based control to 100% automatic control

Solutions implemented

• Software : AX Vision
• Hardware: complete device: camera / lighting / controller / cabling / fixtures...
• Service:
  - Recommendation and sizing of the solutions to the needs of the project
  - Integration and implementation

Technical challenges / Specific points

• Real-time detection at high speed > 100 frames/s
• Detection of transparent elements embedded in a transparent material
• Requirement of compliance thresholds
