visual inspection equipment for dimensional
and surface defects control





and reports

SQUEEZEX is a visual inspection machine for dimensional and surface control of O-Rings and generic circular pieces of rubber. Squeezex is able to check the surface of the workpiece to identify closed-undetectable cuts. The machine is capable of controlling other major failures like burrs, missing material, holes and halos, doble-moulding, roundness, concentricity, etc.

The production process of rubber articles can create cuts localized mainly in the area of the mould parting line that are not visible with the classic no-contact vision systems. SqueezeX solves the problem of controlling these defects deforming the workpiece during the acquisition of images and the software processes in real time the severity of the defect.

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.

After thickness control through a barrage laser, the capture of 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 basic version the machine is equipped with a camera for the dimensional control and two cameras for the surface control (from above and below through the glass of the rotary table).

This machine is flexible and can be integrated with other dimensional and surface sensors.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.
SqueezeX can also work as single table.

  • 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

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 1 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 closure 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.
