Inspection system for roll-to-roll equipment

An inspection system for a roll-to-roll apparatus, which inspects a target object manufactured by a roll-to-roll apparatus that is transferred while partially wound around and supported by an outer circumference of a guide roller in a Y-axis direction, the inspection system comprising:

• a base frame;
• a pair of vision devices which are supported by the base frame while spaced apart from each other in a Y-axis direction and correspond to edges of both sides of a target object, wherein each of the vision devices includes a main illuminator which obliquely emits light with respect to a normal plane of the guide roller to illuminate the target object, a sub-illuminator which illuminates the target object by emitting light to remove a shadow generated by the main illuminator, and a camera disposed between the main illuminator and the sub-illuminator to obtain an image from light reflected by the target object illuminated by the main illuminator and the sub-illuminator;
• an X-axis actuator which moves X-axis stages with respect to Y-axis stages in an X-axis direction so that the vision devices move toward or away from the guide roller while supported by the X-axis stages;
• and
• a Y-axis actuator which moves at least any one of the Y-axis stages with respect to the base frame in the Y-axis direction to adjust a distance between the vision devices,
• wherein each of the vision devices includes:
• a first rotator which rotates a first rotating stage with respect to a rotating block based on an optical axis of the camera in a state in which the camera is supported by the first rotating stage;
• a second rotator which rotates a second rotating stage perpendicularly connected to the rotating block with respect to a moving block based on an axis perpendicular to both the optical axis of the camera and a Y-axis;
• a camera distance adjusting assembly which rotates the moving block with respect to a rotating bracket in an optical axis direction of the camera;
• a third rotator which rotates the rotating bracket with respect to a rotating support based on the Y-axis;
• and
• a Z-axis actuator which moves the rotating support with respect to a pedestal supported by the X-axis stage in a Z-axis direction.
