Matlix is a simple visual inspection machine for the dimensional and surface control of circular and other shape components. Matlix is able to check the surface of the piece to identify main defects as cut, flash, lacking material, holes and halos, doble-mouldings, roundness, concentricity, etc.

The equipment is controlled by a PC managed by an operating system Real-Time that make both the elaborations on the images and the interaction with the operator through simple and intuitive windows interface.

The system Real-Time offers a good stability to the system and extremely elevated control speed. The images are captured by digital industrial cameras and are transferred, without losses or interferences to the PC.

The loading device delivers the pieces to check on a conveyor belt where a motorised diverter will move the parts onto the rotating table. The machine can be employed for the control of high precision gaskets in rubber, plastic, metal and other materials within the limits of the vision field.

After thickness control through a barrage laser, the capture images and the following elaboration, the pieces are sorted in the different areas of accumulation depending on their pass/fail criteria or they can be reworked.

In the MATLIX OS version the machine is equipped with a camera for the surface control from above, while in the MATLIX DS version is equipped with two cameras, one from above and one from the bottom through the glass of the rotating table. In this case, the field of view is reduced to 35 mm and the optimum use is for parts which can not be flipped.

You can view real time statistics and all production times, the number and the type of defects and the state of filling of the accumulation zones, it is possible to save the production reports with graphics and statistic data and to integrate them on the management system for subsequent processing. The statistic software elaborates the data and calculates the values of production capability (CPK), furnishing a feed-back on the production parameters.

Machine downtime is kept to a minimum by the ease of cleaning and component changing together with the storing of all configuration parameters.

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

The barrage laser is able to measure with extreme accuracy the planarity of the piece scanning the pieces along all of its dimension. It is possible to measure the height only in the case of pieces perfectly planar.
The elevated precision of measure is achieved using algorithms of elaboration of the signal that allow to eliminate the imperfections of the rotating table oscillations.

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

  • CCD progressive scan high resolution camera
  • Telecentric lens
  • 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

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

Control program

  • Identify of irregular profiles and relative 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 the surface defectiveness in many inspection areas

This system consist of 6+6 color cameras and 2 levels of color led lighting placed above and bottom of the pieces. Allows you to detect defectiveness on the outside and inside peripheral surface of pieces, anomalies related to the closed of the mould and production defects that frequently are locate in that area.
The control program allows to regulate the two different crowns of led in order to optimize the illumination of the component. Can be defined many independent control areas. It manages the algorithm for the control of the top and bottom areas of mould closing and of course the colors tonality on every image. Check the maximum variation of the basic profile of the piece.
