Fully automated inline quality control with 3D scanner
Robust, accurate 3D geometry and surface inspection for the most diverse materials and surfaces in the production cycle
Stable, robust scanning regardless of environmental conditions with minimum cycle time and high throughput? VITRONIC’s innovative, flexible 3D scanning solution makes it possible.
Components made of all kinds of materials, for example, complex castings, are inspected by the 3D scanner simultaneously from all sides for surface defects and geometric deviations. One of the first of these systems was installed as a turnkey solution in the foundry of an automobile manufacturer. Integrated in the production line, the system inspects crank cases for integrity of external geometries, existence of component openings, and damage and defects (for example, dents).
Robust inspection method to detect geometric deviations
In this process, the sides of the component are scanned simultaneously and each is captured as a 3D point cloud. The point cloud is compared to the 3D model (from the master part) stored for each side and deviations are determined. Flexible, Cartesian-rectangular sections can be defined for each side view. Various tolerance limits for these sections can then be specified in terms of width, length, depth, and volume. This robust inspection method is resistant to component contamination and is extremely stable when surfaces change. The 3D scanner can be used almost anywhere geometric deviations must be detected. In addition to functioning as a stationary scanning solution, it is possible to connect the 3D scanner to a robot.
