DEFECT DETECTION SYSTEM FOR WIRECORD FABRIC

WIPO Patent Application WO/2023/029562

A1

A defect detection system for a wirecord fabric (41), comprising a limiting device for limiting the wirecord fabric (41), a magnetic image acquisition device for acquiring a magnetic image signal of the wirecord fabric (41), and a magnetic image detection device for detecting a defect of the wirecord fabric (41) according to the magnetic image signal. The limiting device comprises a plurality of limiting wheels (11) which are oppositely provided on the two sides of the wirecord fabric (41); the magnetic image acquisition device comprises a magnetic field unit, a magnetic sensor module (221), and a signal processing unit (23); and the magnetic field unit comprises a first permanent magnet module (211) and a second permanent magnet module (212) which are oppositely provided on the two sides of the wirecord fabric (41). The detection system can be used for generating the magnetic image signal of the wirecord fabric (41) on the basis of a change condition of a background magnetic field caused by the wirecord fabric (41) penetrating through the background magnetic field, and for detecting the magnetic image signal.
