  • Publication number: 20240284054
    Abstract: A pair of vision devices are supported by a base frame while spaced apart from each other in a Y-axis direction, wherein each of the pair of vision devices includes a main illuminator which obliquely emits light with respect to a normal plane of a guide roller to illuminate a 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. The X-axis moving unit 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. The Y-axis moving unit 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.
