Abstract
An optical inspection system for controlling the laying of a string or layer of a fluorescent material on a metal piece comprises an optical inspection station including a wall movable between an open condition and a closed condition in which the wall defines a dark chamber wherein the piece to be controlled is confined. With the wall there are associated Wood lamps which illuminate the piece ensuring an optimal inspection by the video camera.
Claims2
An optical inspection system for controlling the laying of a string or a layer of a fluorescent material on a metal piece, said system comprising:
- a transport line with piece-supporting pallets for transporting pieces to be controlled,
- an optical inspection station located on the path of said line, said station comprising:
- wall means movable between an opened condition and a closed condition in which said wall means define a dark chamber wherein the piece to be controlled is confined,
- at least a Wood lamp located on said wall means to illuminate said piece by ultra-violet light after that said piece has been confined within said dark chamber,
- video camera means supported by said wall means for optically inspecting the string of a fluorescent material on said piece, illuminated by the ultra-violet light of said at least a Wood lamp, and
- electronic means for processing output signals from said video camera means and to provide data on the quality of the laying of the string or layer of fluorescent material.
