Robot Calibration Systems

摘要

The robot work finder calibration systems combine a visual datum reference tool with either a manual or automatic tool finder. Two different visual datum reference tools can be used with either an automatic or manual work finder. This technology enables the user to visually see a robotic reference frame, a frame in space that is relative to an industrial robot and workpiece tool that is otherwise abstract. Enabling the user to visually see the robotic reference frame on the 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 tool center point. The tool center 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 really necessary.

1. A robot calibration system comprising:
a. a visual datum reference tool, having a first and second lasers, said first laser emitting a first laser beam, said second laser emitting a second laser beam, said first laser beam intersecting said second laser beam at a tool center point, said tool center point defining the location of a robotic reference frame; and b. a robotic tool finder being disposed onto a robot tool, said robotic tool finder enabling generation of said robotic reference frame, said robotic reference frame enabling calibration of said robot work path; whereby angular positions of said robot tool are adjustable relative to said robotic reference frame.
