This utility model relates to the field of UD fabric
impurity detection technology, and in particular to a finished UD fabric
impurity detection device; it includes a
winding machine, with frames arranged on both sides in front of the
winding machine's inlet, and a gantry support spanning across the frames. The gantry support is located in front of the
winding machine's inlet, and several industrial cameras are mounted on the crossbeams of the gantry support for capturing images of the UD fabric surface; a parallel jet
assembly is arranged along the running front of the UD fabric on the gantry support, and the jet
assembly includes a connecting rod arranged along the width direction of the UD fabric, with a movable sleeve fitted on the connecting rod, and multiple sets of jet modules arranged in an axial array on the sleeve, each set of jet modules including a pressing jet
nozzle and a repelling jet
nozzle; the scientific spacing between the jet
assembly and the imaging unit enables process coordination, and the directional slit
airflow of the pressing jet
nozzle and the
diffusion air curtain of the repelling jet nozzle form a complementary function, fundamentally solving the problems of dynamic missed detection of suspended impurities and airborne
insect intrusion.
