Machine for weaving or winding up fiber structures that can be inspected for abnormalities by image analysis

摘要

The present invention relates to a machine for weaving (10) or winding (20) a fiber preform (28) on a mandrel, the mandrel having a rotational axis (30) that is substantially horizontal to receive the preform. The machine scans the hidden surface of the fiber preform using a plurality of cameras (42) directed to the underside of the fiber preform to obtain an image of the hidden surface, and the image analysis module (40 ) To process the hidden surface image of the fiber preform in a plurality of adjacent scan windows and extract the winding pattern therefrom and compare them with the reference weave pattern pre-stored in the module , A motor (34, 36) for rotating the mandrel about its rotation axis, a control unit (40), and as a result of comparison, at least one In the can window, if the control unit reveals that the difference in appearance between the two weave patterns characterizes the presence of anomalies that are the result of contamination and / or poor weaving in the fiber preform, the control unit Stop rotation.
