Abstract: An optical inspection machine for the quality control of parts, in particular gaskets, comprises a rotary table on which the parts to be inspected are positioned and, above said rotary table, a peripheral viewing unit suitable for inspecting the outer and/or inner side surfaces of a part. The unit comprises a plurality of downward-facing video cameras and, beneath each video camera, at least one angled mirror suitable for reflecting the image of a portion of the outer and/or inner side surface of the part to be inspected.

Abstract: A method for acquiring images of a part to be inspected comprises the following steps framing the part with a digital video camera providing an illuminator comprising a plurality of illumination sources arranged to illuminate various portions of the part or to illuminate the part from different angles, wherein individual illumination sources or groups of illumination sources are controlled individually by means of an illumination control unit operationally connected to the digital video camera; controlling the video camera to take a series of shots of framed part, with each shot being defined by a preset exposure time with each shot and for the duration of the exposure time generating a part illumination condition through the illumination control unit by activating a portion of the individual illumination sources or groups of illumination sources so the sequence of shots is taken with different corresponding lighting conditions according to a preset lighting program.

Abstract: An illuminator for a viewing unit of an optical inspection machine for the quality control of parts, in particular gaskets, comprises a diffusion chamber, a diffuse illumination source, a low-angle illumination source, a direct illumination source placed in the diffusion chamber, and an annular reflective element placed in the diffusion chamber. The annular reflective element is integral to the direct illumination source so that together they form a chamber closure assembly delimiting the upper end of the diffusion chamber. The chamber closure assembly can move axially by translational movement in the diffusion chamber both toward and away from the diffuse illumination source.

Abstract: An optical inspection machine for the quality control of parts, in particular gaskets, comprises a rotary table on which parts to be inspected are placed and, above the rotary table, at least one viewing unit for inspecting one or more outer and/or inner surfaces of a part, a first part ejection station that is activatable to eject a part from the rotary table to a first external conveyor for compliant parts, and a second part ejection station that is activatable to eject a part from the rotary table to a second external conveyor for rejected parts. The viewing unit and part ejection stations are positioned on the rotary table with an angular distance between them, and are connected to a central mounting member that is coaxial to the axis of the rotary table and is movable vertically in relation to the rotary table.
