CALIBRATION FOR ROBOTIC SYSTEMS

摘要

The robot calibration systems combine a work object with an industrial robot and a robot tool. Three different work objects can be used with the system. This technology enables the user to visually see a robotic reference frame, a frame in space that is relative to the industrial robot and workpiece that is otherwise abstract. Enabling the user to visually see the robotic reference frame on the manufacturing shop floor enables adjustment of the robotic frame to the shop floor and correction of a robotic path or off-line program to enhance accuracy. Two laser beams are emitted and intersect at a laser intersection point. The laser intersection point and the laser beams are then used to define a robotic reference frame. The technology improves cost and time factors in applications where absolutely accurate robots are not necessary.

1. A method for calibrating a robot work path on a manufacturing shop floor using CAD means by deployment of a calibration system, said calibration system including a work object, said work object including a first and a second laser, said first laser projecting a first laser beam, said second laser projecting a second laser beam, said first laser beam intersecting said second laser beam at a laser intersection point, the method comprising:
a. securely mounting said work object to a fixture relative to a robot tool, said fixture being positioned on said manufacturing shop floor; b. generating a robotic reference frame, said robotic reference frame including said first and said second laser beams; c. manipulating said robot tool into alignment with said laser intersection point on said manufacturing shop floor, so as to enable calibration of said robot work path for said robot tool relative to said laser intersection point when said work object is mounted onto said fixture; and d. using said robotic reference frame to calibrate said robot work path of said robot tool using CAD simulation software.
