Laser profilometer

The laser Profilometry allows to reconstruct the profile of an object and to measure all its parameters in order to control the dimension, position, inclination and deformation of the object under test.
Through the acquisition of different profiles it is possible to reconstruct the all shape of the object.

The profilometer developed by Loccioni Home is composed of a matrix camera and a laser. The camera evaluates the bending of the laser projected on the area under test. In this way it is possible to reconstruct the 3D image starting from a 2D image, through an algorithm of triangulation. The output of the sensor is the profile of the tested object.

The profile is evaluated by the software which extracts the dimensional information using the image processing technology and compares it to the acceptability limits, in order to give the result GOODor FAIL automatically.

Applications

Profilometry on belt

Belt Inspection System: it measures the correct position of the belt on the pulley of a washing machine.
 

Profilometry on drum

The profilometer (3D inspection) is used to detect those defects impossible to detect only by cameras (2D inspection), such as:
    | steel demaged
    | clamp not properly inserted
    | cutted lifter
 
 

Profilometry on tub

The station, positioned in production line, measures the correct positioning of the seal on the rear tub, calculating:
    | the distance of the lip seal from the internal face of the A-bearing
    | the distance between the lip seal and the plastic
    | the planarity of the seal
 
 

Profilometry on silicone

The station, positioned in production line, measures the dimensions of a silicone strip applied on the steel panel of a dishwasher
    | 2D system (cameras) is used to evaluate width and position
    | 3D system (profilometer) is used to measure the height of the silicon strip
