Optical device of implementation appearance inspection equipment

摘要

(57) [summary] [purpose] The present invention relates to implementation appearance inspection apparatus for inspecting the implementation status of the implementation part of a printed circuit board used in electronic and electrical equipment, the width of the optical axis of the optical device in the mounting inspection system In more narrow, even shorty mounting components and an object thereof is to provide an optical device mounting visual inspection apparatus which can improve the detection accuracy. [Configuration] The reflected light is irradiated from a light source implemented printed board at a predetermined angle light, by obtaining image data by scanning with a camera consisting of a CCD sensor 6a and a lens 6b, and the implementation of the printed circuit board 2 In mounting the appearance inspection apparatus determines the presence or absence of components, is interposed a cylindrical lens 10 between the mounting printed circuit board 2 to be inspected and the lens 6b, and consists in narrowing the width of the optical axis of the camera.
