visual inspection equipment for dimensional
and surface defects control





and reports

Phoenix is the latest evolution of our machine for visual inspection, dimensional and surface control of circular and other shape components. Phoenix is now the most advanced product of UTPVision and is able to control all the surfaces of the workpiece using the optical inspection through the glass (up to a maximum size of the piece of 50 mm).

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.

Phoenix can be employed for the control of high precision gaskets in rubber, plastic parts, 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.
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 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:

  • Storing of all configuration parameters
  • Automatic positioning of optics
  • Automatic positioning of mechanical devices
  • Automatic adjustment of the table and belts speed
  • Easy cleaning of the machine and the loader
  • 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 height and 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, 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 analysis and 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 two levels of color led lighting placed above and below the piece. Allows you to detect defectiveness on the outside 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 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.
