Fig.1 Schematic diagram of platform for surface defects of
Si3N4 ceramic bearing ring
Driven by the motor and acted by the reducer, the
Si3N4 ceramic bearing sample is
transferred by the coaxial transmission device. And the mechanical arm
transfers the sample to the image acquisition module to complete the
feeding process. The stereo microscope magnifies the tiny defects on the
surface of Si3N4 ceramic bearing inner
ring, the hemispherical LED light source provides sufficient light. The
high-speed CCD camera acquires the surface defect images. The collected
defects are connected to the industrial PC via image acquisition card
and image memory card, respectively through bus and serial port.
