The invention discloses a non-contact scroll saw guide wheel slot type
detector, comprising a seat body for supporting a workpiece to be measured, an
imaging lens and a
computer processing element, wherein a CCD
imaging lens is arranged above the workpiece to be measured corresponding to the side face of the seat body; a high-brightness
white light LED adjustable
light source and an X-axis and Y-axis measuring liner scale are arranged below the workpiece to be measured corresponding to the side face of the seat body; the
imaging lens is fixed on the liner rail arranged on the seat body; and the trend of the rail is parallel to the axle center of the workpiece to be measured. When in measurement, the
detector leads the central direction of the imaging camera to be tangent to the surface ofthe workpiece to be measured, projection imaging is carried out on the surface groove profile of the workpiece to be measured, the image can be amplified by
processing of
computer program after imaging to be displayed on
software operator interface, therefore, the imaging on the workpiece is amplified for scores even hundreds of times after the above processes; in addition, a user can
label multiterms of data such as groove spacing, angle, groove profile depth and the like of the workpiece to be measured according to
image analysis software, and flaws on the surface of the workpiece to be measured can also be amplified and displayed on
software interface, thereby being convenient for a
client to detect and trace the quality of products.
