Fiberglass AI Visual Inspection Equipment
Fiberglass AI visual inspection equipment targets fiberglass cloth / mat, performing inline inspection of yarn breakage, missing weft, stains, thickness, fuzz, holes, poor overlap and other defects, with OK/NG output and production line interlocking.
Materials Overview
Transparent fiber + resin, with the focus on fuzz and overlap
Fiberglass AI visual inspection equipment images fiberglass fabric or mat; the algorithm identifies defects such as yarn breakage, missing weft, stains, thickness anomalies, fuzz, holes and poor overlap, outputs OK/NG results and interlocks with the production line.
Fiberglass cloth / mat is woven or laid from glass fiber; the fiber itself is nearly transparent with a silky sheen and is often combined with resin. Its difficulty is "transparent fiber + fuzz": fuzz is a single fiber standing up, with weak contrast against a nearly transparent background; poor overlap (misalignment when laying multiple plies) also requires alignment judgement.
Defects specific to fiberglass include yarn breakage, missing weft, stains (resin spots or oil stains), uneven thickness, fuzz, holes and poor lapping. Fuzz and yarn breakage affect the surface and strength of the subsequent part and are key items.
Inspection uses AI to build a model of the normal weave / web formation and judges yarn breakage, fuzz and lap offset as defects; changing the weave (plain / felt) mainly requires adjusting the recipe.

AI Inspection Principles
AI Visual Inspection Principles
Fiberglass inspection is difficult because of "transparent fiber + fuzz". The algorithm builds a model of the normal weave / laid web and classifies yarn breakage, missing weft, fuzz and lap offset as defects. Fuzz has weak contrast against a near-transparent background, so sufficient resolution and suitable illumination are needed.
For illumination, diffuse light gives uniform lighting to see stains and thickness; backlight is used for holes; low-angle light exposes fuzz and surface relief. With transparent fibers, reflection interference must be controlled.
For judgement, we recommend setting yarn breakage and fuzz as high priority and judging laps by offset tolerance. Specific thresholds must be confirmed by measured testing of OK / NG samples.
