ARTIFICIAL INTELLIGENCE

BigX is a visual inspection machine designed to control all the surfaces of medium size O-Rings, with a control range between 70mm of internal diameter and 200mm of external. BigX uses the optical inspection combined to several piece manipulations for the best piece positioning under the cameras.

Pieces are checked through a series of stations for defects detection using digital industrial cameras. All pictures captured are transferred to a computer with a Real-Time operating system for image processing. Interaction with the operator is simple and intuitive thanks to its user-friendly interface.

Pieces are sorted in different areas of accumulation depending on their pass/fail criteria. Statistics and production times are available in real time, including number/type of each defect and accumulation zones filling status. It’s also possible to save production reports with graphics and data for afterwards analysis.

Five Surface Cameras

Unloading System  

ILLUMINATION

  • Digital regulation of the bright intensity for inside and outside surfaces
  • Possibility to control piece with reflecting surface
  • Good precision of dimensional and surface control
  • No decadence of the bright intensity 

 

DIMENSIONAL STATION

Independent measurement station for dimensional control, with the following characteristics:

  • Progressive scan high resolution B/W camera
  • Nearly zero distortion bi-telecentric lenses
  • Dedicated lighting system

Control Program

  • Measurement of the inner/outer diameter
  • Measurement of the radial cross section
  • Measuments of general lengths, angles, radii
  • Flash defects inspection
  • Nicks defects inspection
  • Roundness inspection
  • Center distance

 

CONTROL DEVICE OF THE WHOLE SURFACE

This system has 5 color cameras and two levels of led color illumination system positioned around the piece to inspect. This allows to identify any defects on the entire surface of the piece. The inspection program allows you to adjust two different LED illumination crowns for the lighting optimization of the piece. Several independent controls can be defined.
