The intelligent cameras 3D of Sick the best allied in setting for Ford Germany

The company Ford faithful to his origins has chosen the technology Sick to realise the setting of his production Ford Germany. Ford remembers that when inventing the line of production does a century, Henry Ford established the bases for the massive production of vehicles. The requirement to attain it consisted in using processes of repetitive work and identical pieces. Nowadays they are especially the robots those that occupy of these activities in the lines of production of bodyworks and of setting. In Ford Germany, the Borrmann Company has instrumented a line of setting of bumpers, cover of maletero and capós with eight intelligent cameras IVC-3D of Sick. These cameras serve to detect exactly the positions of atornillado employed later to guide the robot of visual form.
The image reflects the moment in which the camera 3D of sick attracts the components mechanised of the platform of setting Ford.
Ford and Sick are conscious of the precision that requires the platform of setting so much to functional level like aesthetic. With the end that the shots of design more attractor trucks have a harmonic appearance and homogénea in the vehicle finished, all the components of the bodywork have to insert and atornillarse on her with a precision of a tenth of millimetre. The cameras IVC-3D of Sick help to achieve it; his method of triangulation laser especially resistant to the environingingmental light and his high resolution provide the degree of precision required.
The bumpers install in what it knows like a station of geometry. When a bodywork in the rough arrives to the station on a patín of transport, does go down a unit of geometry, instrumented in both sides with profiles of reference in shape of W, on the bodywork and subject to her. To continuation, two intelligent cameras 3D measure the position of the components in relation with the bodywork in the rough. Basing in the position of the tip in relation with the location of the lateral surfaces, the software calculates the position with a precision of a tenth of millimetre, transmitting the positions of atornillado exact to the robots by means of an interface RS-422.
The innovative technology of sick provides an intelligent measurement and an exact detection
In the workshop of setting of capós is not possible to use an aim of reference atornillado, by what the surface of the bodywork and the position of the orifices of main reference serves like norm of reference. With this aim, two intelligent cameras 3D measure first the complete outline of the bodywork in the rough and afterwards determine the exact position of the orifices of main reference. During the measurement, the cameras displace on a sliding linear and, from the data of the 'encoder' of this last, is possible to assign to each measurement a clearly determined position of the cameras on the bodywork in the rough.
To determine with precision the position of the bodywork, the software evaluates the position of the orifices of main reference and synchronises the results of the measurements of both scanners. This process provides all the coordinates and angles required for atornillar the components perfectly using tools of automatic setting for the screws and the nuts.
Example of intelligent camera IVC-3D produced by the engineering Borrmann employing IVC-Studio.

Both applications of measurement were developed by the signature of engineering Borrmann employing IVC-Studio. The processing of the images effects in IVC-Studio, evaluating each one of the four cameras in a system based in PC. Although the two tasks of measurement are different, Borrmann can use the same cameras and the same software of application, what facilitates considerably the set up and contributes flexibility. The result is the possibility to adjust the systems of fast and simple way to new geometries of measurement and positions of reference even when the models of vehicle change en el futuro.
