Title:
OPERATING PROGRAM CORRECTION METHOD AND WELDING ROBOT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/173655
Kind Code:
A1
Abstract:
Provided is an operating program correction method which corrects an operating program of a welding robot (1) which welds members (W) to be welded, the method comprising: a step for extracting data on predetermined members (W) to be welded from 3D CAD data; a step in which a sensor images members (W) positioned by the welding robot (1), a step in which a plurality of faces are acquired from the data of the imaged members (W) to be welded, a step in which the largest face having the largest surface area of the plurality of faces is acquired, a step in which at least two vertices (X1, X2) on the largest face are extracted, a step in which a camera (12) captures images of the members (W) to be welded which have been positioned by the welding robot (1), a step in which two vertices within the image corresponding to the two vertices are extracted from the captured image data of the members (W) to be welded, a step in which the difference between the coordinates of the two vertices (X1, X2) and the coordinates of the two vertices within the image is acquired, and a step in which the operating program which operates the welding robot (1) is corrected on the basis of this difference.
