1. 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 angle adjusting assembly which adjusts an angle of the main illuminator with respect to the guide roller by tilting a first tilting block with respect to an illuminator support based on a Y-axis in a state in which the main illuminator is supported by the first tilting block;
a second angle adjusting assembly which adjusts an angle of the sub-illuminator with respect to the guide roller by tilting a second tilting block with respect to the illuminator support based on the Y-axis in a state in which the sub-illuminator is supported by the second tilting block; and
an illuminator distance adjusting assembly which adjusts distances from the guide roller to the main illuminator and the sub-illuminator by linearly moving the illuminator support.
