Title:

DEVICE AND METHOD FOR CALIBRATING ELONGATED METALLURGICAL TOOL BASED ON LASER RANGING SENSOR

Document Type and Number:

WIPO Patent Application WO/2021/259313

Kind Code:

A1

Abstract:

A method for calibrating an elongated metallurgical tool based on a laser ranging sensor (6). A temperature measurement/sampling tool (3) is driven by an industrial robot (1) to make a standard temperature measurement/sampling gun (4) enter a calibration area, the standard temperature measurement/sampling gun (4) reciprocates at the vicinity of a laser ranging sensor (6), the standard axis is obtained by using a vector on a bus of the standard temperature measurement/sampling gun (4) based on the laser ranging sensor (6), the posture of the temperature measurement/sampling tool (3) is adjusted so that the axis of the standard temperature measurement/sampling gun (4) is parallel to the set standard axis, and moreover, positioning identification is performed on a end TCP point of the temperature measurement/sampling tool (3) to obtain a tool coordinate system corresponding to the temperature measurement/sampling tool (3), and deformation of the standard temperature measurement/sampling gun (4) can be detected in the calibration process, to ensure the accuracy and stability of system operation of the industrial robot (1). In addition, also provided is a device for calibrating an elongated metallurgical tool based on a laser ranging sensor (6).
