Advanced Materials AI Visual Inspection Equipment

Advanced materials AI visual inspection equipment: imaging is configured to the material's optical properties and then AI acceptance criteria are configured, targeting surface defect inspection of advanced materials such as carbon fiber prepreg, optical film, foam and tape; internal properties require non-destructive testing.

Products Overview

An advanced materials inspection platform that configures imaging to the material's optical properties and then applies AI-based criteria

Quick answers

Advanced materials AI visual inspection equipment serves carbon fiber prepreg, fiberglass, aramid, various high-performance films, foam and tape, configuring imaging to each material's optical characteristics and then applying AI criteria to inspect surface defects; bulk properties such as internal delamination and porosity require ultrasonic / X-ray or physical-chemical testing.

"Advanced materials" is not one product but a collective term for a class of advanced materials — carbon fiber prepreg, fiberglass, aramid, various high-performance films, foam and tape. What they have in common is: New materials, many specifications, and defect standards are often still being established. A single fixed hardware setup cannot cover everything; inspection must start from "material optical properties".

The core logic of this type of inspection is "Configure imaging according to the material's optical properties, then set the AI acceptance criteria". Fabric and prepreg require suppressing fiber specular gloss; transparent film requires transmitted light to find holes; foam requires distinguishing foam texture from genuine defects; tape requires accounting for release paper pattern interference. Different materials require different imaging solutions — this is the essence of "advanced materials inspection equipment".

The boundary must be clearly defined: internal delamination, porosity, resin content, and similar properties fall under Bulk material properties, they cannot be judged by surface vision and require ultrasound, X-ray or physical and chemical testing. Making this boundary clear is what makes the solution defensible, and it avoids disputes at the acceptance stage about "why internal defects were not detected".

  • Positioning: a class of inspection platform for advanced materials rather than a single product
  • Core logic: imaging matched to the material's optical properties + AI acceptance criteria
  • Material differences: fabric / film / foam / tape each require different imaging methods
  • Boundary: internal defects require non-destructive / physical and chemical testing; surface vision only covers the surface and contour

Core Functions

What the Equipment Can Do and How Far It Can Go

Imaging Configured by Material

Different optical properties call for different illumination and camera setups, not fixed hardware.

Reflection Suppression for Fabric / Prepreg

Coaxial light / polarization suppresses the specular sheen of fibers so highlights do not drown out defects.

Transmissive Inspection of Transparent Film

For PET / PI / OCA, transmitted light checks for holes and break points.

Foam Texture Differentiation

The algorithm distinguishes normal foam texture from true defects to avoid false calls.

Handling Interference from Tape and Release Paper

Recognize the release paper texture and avoid treating the texture as a defect.

Well-Defined Boundaries

Internal defects are referred to non-destructive / physical and chemical testing, with no exaggerated promises.

Fiber specular gloss interferenceSpecular highlights on fabric / prepreg surfaces mask defectsRequires reflection-suppressing illumination (coaxial light / polarization)
Transparent film holes / pinholesPinholes and holes in PET / PI / OCA filmTransmitted light gives the highest contrast for holes
Foam texture causes false callsNormal pores are mistaken for defectsMust distinguish foam texture from real defects
Interference from tape and release paper patternsRelease paper texture misjudged as a defectRequires a dedicated algorithm to distinguish
Surface foreign matter / inclusionsFibers, particles and gel particles mixed inVaried shapes, suited to deep learning
Color difference / uneven coatingInconsistent color or coating within the same material batchRequires stable light source and datum
Delamination / bubbles (visible on surface)Interlayer separation, surface blisteringRequires multiple angles or specific illumination
Internal Delamination / Porosity / Resin ContentBulk material property defectsBeyond the scope of surface vision; requires ultrasonic / X-ray / physical and chemical testing
Internal delamination, porosity, and resin content are properties of the material itself and cannot be judged by surface vision; they require ultrasound, X-ray, or physical and chemical testing — this point is key to the credibility of this page. Surface vision covers only the surface and contour.

Relationship Between Imaging and Judgement

The success of advanced materials inspection depends on "whether the imaging solution matches the optical properties of the material". With the same hardware, if the lighting is not matched to the material, fabric will be drowned out by reflection, transparent film will be overexposed, and foam will have its pores treated as defects. The core of such equipment is therefore not fixed hardware but the ability to map "material -> optics -> acceptance criteria".

Vision System

How Cameras, Lenses, Light Sources and Controllers Are Configured

industrial camera

Select area-scan or line-scan by material area and minimum defect size; continuous web feeding usually uses line scan

  • Area-scan camera: fixed-shot, single-piece, intermittent feeding
  • Line Scan Camera: Continuous Feed, Wide Format
  • Back-calculate the pixel size from the smallest resolvable defect

lens

Determines field of view, distortion and depth of field; use telecentric lenses for dimensional measurement

  • Standard industrial lens: appearance inspection
  • Low-distortion lens: edge judgement on large areas
  • Telecentric lens: hole diameter, contour, dimensional measurement

Light Source and Illumination

Whether defects in advanced materials can be captured depends largely on whether the illumination matches the material's optical properties

  • Diffused light: color difference, stains
  • Low angle / stripe light: scratch, indentation
  • Transmitted light: holes and short shots in transparent film
  • Coaxial / polarization: suppresses reflections from fabric and prepreg

Controllers and Industrial PCs

The platform for running algorithms, outputting results and interlocking with the production line

  • Industrial Computer or Vision Controller
  • Light source controller dimming synchronized with strobing
  • Interacts with the PLC to complete interlocking, alarming, and rejection

AI algorithm

Choose the Algorithm by Defect Form, Not by Complexity

Template Matching and Positioning

Locate first, then judge, to establish a stable coordinate system

  • Shape / grayscale matching: suited to fixed stations
  • Region segmentation after alignment avoids false calls caused by drift

Blob and Morphological Analysis

Defects with obvious gray-scale / color differences, such as stains, holes and foreign matter

  • Threshold segmentation → connected-component statistics
  • Depends on stable illumination

Edge and Contour Measurement

Judgments for dimensions, contours, hole positions, and spacing

  • Sub-pixel edge extraction
  • Line / circle / arc fitting and calculation

Deep Learning (Classification / Detection / Segmentation)

Defects with varied shapes that are hard to describe by rules, such as foam texture anomalies and foreign matter

  • Requires OK / NG Sample Training
  • Supports pixel-level segmentation to output defect size and position
  • Sample coverage sets the upper limit

Automatic Alarm and rejection

How inspection results act on the production line

Inspection results are not only shown on the screen. Material judged NG must have its position marked, be rejected or sorted by interlocking, and have its images and judgement results archived for re-judgement and traceability.

The alarm method is set according to on-site practice: audible and visual alarm, pop-up window, PLC set bit, or all three at once. Critical defects and general defects can be handled differently — the former stops the machine and alarms, while the latter is only marked.

  • 01 Defect judgement result generation
  • 02 NG marking and alarm trigger
  • 03 Image and data archiving
  • 04 Production line interlocking rejection / sorting

data traceability

Records, Queries and Quality Closed Loop

Per-Piece Records

The judgement result, defect type, position, and timestamp of every part are stored in the database

  • Search by time / batch / defect type
  • NG image retention for re-judgement

Batch and Recipe

Different materials use different recipes, called up at changeover to reduce manual parameter tuning

  • Recipes store the inspection region, thresholds and algorithm parameters

Production Line Data Integration

Exchange inspection data with the MES / host system

  • Output pass rate and defect distribution
  • Interface method is subject to site conditions

Common Question

What Is the Inspection Accuracy of the Advanced Materials Inspection Equipment?
To be supplied: inspection accuracy is directly related to the material, imaging solution, and camera resolution and cannot be summarized by a single uniform number. Different materials require different illumination and judgement logic, and the minimum detectable defect size must be confirmed by measurement once the material and solution are fixed.
Why can't one hardware setup inspect all advanced materials?
Because the optical properties of different materials differ greatly: fabrics have specular gloss, transparent films require transmission, foam requires texture differentiation, and tape is affected by release paper. The imaging solution must be configured per material, which is why "advanced materials inspection" is essentially a platform rather than a stand-alone machine.
Can holes in transparent film be detected?
Yes. Transmitted or backlit imaging is usually used; holes appear as clear bright spots with high contrast. The minimum hole diameter that can be reliably detected depends on camera resolution and field of view, and must be measured according to the actual material and hole diameter requirement.
Will normal foam pores cause false calls?
This is the typical difficulty with this type of material. The approach is to let the algorithm learn the normal foam texture features of conforming products and judge significantly deviating areas as anomalies rather than using fixed thresholds. A sufficient quantity of conforming samples is needed for training.
Can internal delamination and porosity be detected?
No. That is a bulk material property. Internal delamination, porosity and resin content require ultrasonic, X-ray or physicochemical testing methods. Visual inspection only covers the surface and contour; the two are complementary, not substitutes.
What materials can be inspected?
Carbon fiber prepreg, fiberglass, aramid, PET / PI / OCA film, foam, conductive fabric and die-cut tape are already covered. If a new material is not on the list, samples must be provided for imaging feasibility validation before evaluation.
What Information Do You Need to Provide?
Recommended to provide: OK / NG samples of each material, a description of the material's optical characteristics, quantitative defect criteria, line cycle time and the loading method, and the on-site communication method. For advanced materials it must also be clarified who provides the defect judgement baseline.

Submit sample testing

Advanced materials vary widely, so illumination must be configured on actual material samples. Please provide OK / NG samples of each material; we will validate the imaging and judgement solution separately for each according to its optical characteristics, and define the coverage limits of surface vision.
