Cross laser calibration device and calibration system using the same

A calibration system used to calibrate a tool center point of a robotic arm, wherein the calibration system comprises:

• a coordinate orifice plate having an orifice center point;
• a set of cross laser sensors arranged on the coordinate orifice plate to generate cross laser lines intersecting at the orifice center point;
• and
• a rotational and translational movement mechanism used to drive the coordinate orifice plate and the set of cross laser sensors, wherein the rotational and translational movement mechanism comprises:
• a first motor used to drive a uni-axis actuator to generate a translational movement in the first direction;
• a second motor fixed on the uni-axis actuator to generate a rotational movement perpendicular to the first direction;
• and
• a connecting rod connected between the second motor and the coordinate orifice plate, wherein, the orifice center point has an off-axis setting relative to a center point of the second motor;
• and
• a processing unit used to receive an initial position information of the robotic arm and two rotation angle signals of the first motor and the second motor and to control the first motor and the second motor to rotate.
