Abstract: A cross laser calibration device used to calibrate a tool center point is provided. The calibration device includes a coordinate orifice plate, a set of cross laser sensors and a rotational and translational movement mechanism. The coordinate orifice plate has an orifice center point. The set of cross laser sensors is arranged on the coordinate orifice plate to generate cross laser lines intersecting at the orifice center point. The set of cross laser sensors is driven by the second motor to rotate around the center point of the second motor, wherein the orifice center point has an off-axis setting relative to the center point of the second motor.
