| Résumé : |
In order to improve production processes, it is important to identify the potential root cause of failures and to trace those. Production data that can be assigned to individual components are the key to this. Together with a research institute, an automotive supplier has equipped a pilot production line for diesel injectors with marker-free tracking technology. |

- Surface microstructure as fingerprints
- Tracking of smell components only possible without marking
- Robustness, data processing and speed
- 99.95 % of the components reliably identified
- Fig. 1 : Component identification on the basis of the surface structure : The components are registered at the matching machine with the help of the track & trace fingerprint reading system
- Fig. 2 : Optics and illumination of the track & trace fingerprint reading system are adapted to the application. The system uses standard components of industrial image processing
- Fig. 3 : CRI2 Solenoid Valve Injector with a round armature component in the middle. Track & Trace Fingerprint takes six fingerprints of the pose surface for identification
- Fig. 4 : Image of the same component for fingerprint registratin and identification in the assembly line. In the high-resolution camera image, the microstructure ant ehd multitude of matches of the reflective surface become visible. The blue and green markings indicate the result of image pre-processing for software positioning of the armature
- Fig. 5 : Image of the same component for fingerprint registration and identification in the assembly line. In this image, some matching microstructures can be seen. The other image section in each case shows stronge differences. The component was nevertheless reliably identified |
