Optical Dimensional Control

Optical Dimensional Control metrology is always based on the construction of contours extracted by Edge Detection algorithms.
Imagina srl algorithms can be configured to obtain the best accuracy and the best morphological/geometrical fitting.
Telecentric lens are special lenses which have constant magnification. This feature is especially useful when measuring:

  • Length, distance, diameter of holes and depth of mechanical details
  • Angle between segments
  • Import/Export of geometrical information in dxf format

Thread Control

Many mechanical parts can be measured and controlled by fully telecentric systems. (telecentric optics with telecentric coaxial illuminators). This configuration is able to guarantee an ideal optic coupling. The performance of accuracy may be increased by the use of linear cameras.

Control Of Sharpening Machines

The possibility of importing DXF profiles and accurate calibration make it possible for the operator to check the cutting operation. The acquisition of an encoder signal means that the system can be synchronized with mechanical axes XY.

Control Of Production Machine Of Torsion Springs

Control length/diameter spring diameter application. This application can check in real time every spring produced on line (up to 10pz/s). The vision system directly drives the feedback of the actuators which move the utensils that control length and diameter values. An automatic discarder controlled by the vision system separates the springs out of tolerance from those in tolerance.

Optical Bench For The Control Of Telecentric Optics

This system checks and verifies resolution (MTF), radial and trapezoidal distortion, working distance, real magnification and telecentricity. The application measures these parameters ad compares them with the nominal value, and produces a test report of the optic.

Diameter And Bending Radius Control

The vision system verifies that pieces to be mounted are in tolerance. The diameter of a shaft and the radius of a sphere are measured. If the pieces measured do not satisfy the tolerance constraints they are automatically rejected. Also in this case telecentric lenses are extremely useful in guaranteeing accurate performance.

Rolling Control

A heated plane (1100 C) has to be rolled. Its dimensions are measured until the nominal thickness is reached. During the rolling process the temperature decreases. The vision system automatically adjusts the exposure time and the optical focus while the temperature is changing. The PLC checks continuously for the data communication and modifies the rolling parameters.
