Find the crack before the cutter finds it for you

A surface defect is cheapest to catch while the product is still one piece. This system inspects the top and both side surfaces as the panel travels toward the cutting station, so a defective piece is identified before the cut rather than discovered in the yard.

It pairs a 2D camera array with thermal imaging, because the two see different things. Visible cracks show up in 2D. Low contrast and hidden defects show up as temperature differences. Both sit behind a dust protected enclosure, because a concrete plant will coat an unprotected lens within a shift.

DETECTION SCOPE

The crack patterns the models are trained on

  • Thickness cracks running through the depth of the panel.
  • Left side and right side cracks on the vertical faces.
  • Centre cracks running across the full face.
  • Centre bottom cracks near the lower edge of the face.
  • Diagonal cracks crossing the face at an angle.

The system targets defects visible to the human eye. The smallest size that can be resolved depends on the camera, lens and working distance selected during scoping, and is confirmed by testing against your actual product samples.

HOW IT WORKS

Three parts, none of which works without the others

Two imaging modes cover two different failure signatures. The third part exists because the first two are useless once the glass is dusty.

2D camera system with AI

Detects visible surface defects and captures the image for the record. The model learns the different defect types and copes with the variation in surface appearance that comes with a concrete product.

In scope

Thermal camera system

Detects the temperature variation caused by hidden or low contrast defects, identifying cracks and abnormalities that do not present under normal lighting.

In scope

Dust protection

An enclosed cover with protective transparent glass and a continuous air blower keeps dust off the glass, so detection stays stable across a full shift instead of degrading through it.

COVERAGE

Three surfaces, and we say so plainly

  • The top surface and both side surfaces are inspected, each by its own camera and lighting array.
  • The front, back and bottom surfaces are not inspected. On a moving line they cannot be reached reliably, and we would rather scope that out than claim coverage we cannot deliver.
  • Camera count, lens choice and working distance are set during scoping against your line speed and panel dimensions.

WHAT A DEPLOYMENT INCLUDES

Built as a station, not a bag of parts

  • Vision setup. Area scan cameras, lenses, thermal cameras, bar lighting and lighting controllers, sized to the surfaces being inspected.
  • Vision controller. An industrial PC with frame grabbers and the deep learning software licence. The cameras are PC based and run against this controller.
  • Structure and enclosure. Camera and lighting mounting structure, the dust protected cover with transparent glass and air blower, power, sensors and wiring, control panel and racking.
  • Recipe programming and AI training. Inspection recipe, model training for your product variant, operator training, then on site support and fine tuning after commissioning.
