Steel strip micro holes detecting device, has upper and lower chassis for supporting laser diode and photo diodes in origin of laser diodes, respectively, where photo diodes are sensible to light emitted by laser diodes
The device has a vertical frame (100) interposed on a path of steel sheet through a horizontal slit delimiting the frame in two upper (110a) and lower chassis (110b). The upper and lower chassis support laser diode (210a) and photo diodes (310a, 310b) in an origin of the laser diodes, respectively, where the photo diodes are sensitive to light emitted by the laser diodes.
