AUTOMATIC CIRCULAR SAW TOOTH INSPECTION SYSTEM AND METHOD

摘要

A method and a system for inspecting first and second surfaces of a cutting member, such as a tooth of a carbide tooth circular saw blade, the cutting member being movable to position the surfaces to be inspected within an inspection zone. First and second video cameras provide output signals representative of the images of the first and second surfaces, respectively. A computer analyzes the output signals and calculates selected attributes of the surfaces presented for inspection. A frame grabber captures video images of the surfaces. A first video monitor displays images of the surfaces being inspected while a second video monitor displays graphical data relating to selected geometrical attributes of the surfaces. Video image data and an appropriate algorithm to control a servo motor to accurately position the cutting member in the field of view. Upper and lower semicircular light transmitters, provide a sharp contrast between the surfaces under inspection and the background.
