Our case studies, industry by industry

Integration into your system or turnkey machine: for each inspection in production, the initial need, the chosen solution and its figures.

Industry

Type of inspection

Plastics

Capsule integrity inspection with artificial intelligence

The needDetect inclusions and missing material too variable to be described by rules, and know which mould cavity each capsule comes from.

The solution

  • Camera with an artificial intelligence system
  • Deep learning algorithm
  • Detection of inclusions and missing material
  • Traceability through the mould cavity number
AISurfaceTraceability
Automotive

Dashboard inspection

The needCheck that an assembled dashboard matches its reference on hundreds of points, from the kanban batch to packing.

The solution

  • Conformity of kanban batches, of the finished product after assembly and of packing
  • One or more very high-resolution cameras
  • More than 250 checks
  • Traceability and statistics of results with the images

Automotive

Robot guidance for handling cylinder heads

The needRecognise the type of cylinder head presented and guide the robot to pick and place it, whatever the reference.

The solution

  • Camera mounted on the robot
  • Identification of the cylinder head type
  • Robot guidance for picking
  • Robot guidance for placing
