Visual inspection machine for dimensional and surface defects control





and reports

Pharma is the latest evolution of our machine for visual inspection, dimensional and surface control of rubber pharmaceutical components. Pharma is now the most advanced product of UTPVision and is able to control all the surfaces of the workpiece using the optical inspection and the through the glass technology up to a maximum size of the piece of 35 mm.

Hermetically seal and no-contamination is absolutely mandatory for the function because these items are in contact with pharmaceutical liquids. For this reason the defects inspection Is the most performant that UTPVision can offer. The system Real-Time offers a good stability to the system and extremely elevated control speed till 45.000 pcs per hour.

After thickness control through a barrage laser, the captured 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. 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.

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 feeding speed
  • Easy cleaning
  • 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 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
  • Simultaneous analysis of the surface defectiveness in many inspection areas

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 diameters
  • Measuments of general lengths, angles, radii
  • Flash defects inspection
  • Nicks defects inspection
  • Roundness inspection

This system consists 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 and inside peripheral surface of pieces, anomalies related to the mould and production defects that frequently are locate in these areas.
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.

Other features:

  • VIM designed for clean room installation
  • Closed system with filter unit to provide the best cleanliness
  • Possibility of metal detector device
