ARTIFICIAL INTELLIGENCE

MatliX is a simple visual inspection machine with single table for the dimensional and surface control oring and generic pieces in rubber, plastic, PTFE. MatliX is able to check the surface of plastic, rubber and other materials pieces to identify main defects as cut, flash, lacking material, holes and halos, doble-mouldings, roundness, concentricity, etc... 

There are four versions of the machine with different accuracies and dimensional characteristics. 

In the MatliX OS versions the machine is equipped with a camera for the surface control from above, while in the MatliX DS versions is equipped with two cameras, one from above and one from the bottom through the glass of the rotating table.

For each configuration, the loading group with rotating vibratory provides to supply the pieces to be checked on a conveyor belt where a motorized diverter transfers the pieces on the rotating table. From here the pieces pass through a series of stations responsible for checking defects using digital industrial cameras.

The images obtained are transfered, without data loss or disturbs, to a PC managed by a Real Time system that performs both image processing and interaction with the operator through a simple and intuitive window interface. The Real-Time system allows excellent system stability and extremely high control speeds.

After capturing the image and processing it, the pieces are sorted into three different accumulation areas depending on whether they are compliant, non-compliant or recovered. The times are very short for the change of piece to be checked thanks to the saving of all the configuration parameters and the rapid cleaning of the machine and the loader.

ILLUMINATION

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

 

LASER THRUBEAM SENSOR

Laser thrubeam sensor is able to measure with extreme accuracy the planarity of the piece scanning the pieces along all of their dimension. It's possible to measure the height only for pieces perfectly planar. The elevated precision of measuring is achieved using algorithms of elaboration of the signal that allow to eliminate any imperfection of the rotating table during its oscillation.

 

DIMENSIONAL STATION

Independent measurement sensor for dimensional control of circular pieces, with the following characteristics:

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

Related control program features

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

 

CONTROL SOFTWARE 

The software for analysis and control of components with complex shape allows the recognition of planar rotation of piece. It also recognizes the top and bottom sides and independently process the image of the piece regardless of load position.

Control program

  • Irregular profiles identification and related control with reference to the sample profile
  • Control of the maximum and minimum height of holes and flash on linear and curvilinear profiles
  • Definition of multiple calibers and control of their dimensions
  • Control of the median and punctual variation of cord sections
  • Simultaneous analysis of surface defectiveness in many inspection areas

OPTIONAL: CONTROL DEVICE OF EXTERNAL AND INTERNAL SURFACES

This system consists of two stations (internal side and external side) with each 6 progressive 2 Mpixel color scan cameras, with framing of the outside and inside of the piece every 60 °. Each camera has a very low distortion lens. In addition, the system is characterized by 2 levels of colored LED lighting arranged above and below the piece.

The system allows to optimize the illumination of the piece thanks to the independent regulation of the illuminators with pulsed light.

The control program allows you to detect defects on the external and internal edge of a piece and anomalies related to the mold closure and production defects that frequently occur in that area.

The stations for inspection on the internal and external lateral surface have the following characteristics:

  • 6 progressive scan 2 Mpixel color camera with internal piece framing every 60°
  • Low distortion optics with global motorized focus adjustment
  • Green light dome illuminator and red low angle illuminator, independently
