Embodiment Construction

[0041] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0042] Such as Figure 1 to Figure 4 As shown, the present invention corrects the method for the error of off-line programming of industrial robots in the field as follows:

[0043] First of all, the on-site layout is carried out in the off-line programming simulation of industrial robots, and the industrial robots are placed. Then select two points in the entire layout to place industrial cameras, and these two points need to be special, convenient, and easy to place. angle). Then, establish a new coordinate system based on these two industrial cameras: take the position of one of the industrial cameras as the origin of the coordinate system, the direction of the line connecting with the other industrial camera is the positive direction of the X axis, and the direction of the optical axis of the industrial camera is Y The positive direction of the axis, a...

Abstract

The invention discloses a method for correcting errors of industrial robot offline programming on spot and belongs to the technical field of industrial robot offline programming. According to the method, offline programming simulation of an industrial robot is carried out in a computer, the specific positions of two industrial cameras are determined, a new simulation coordinate system is established, the positions of two correcting points and the coordinate values of the two correcting points are determined in the new coordinate system, and three feature points, within the shooting range of the two industrial cameras, on the industrial robot and the coordinate values of the three feature points are determined; on spot, the two industrial cameras are arranged according to the simulation position and shoot the correcting points, and the coordinates of the correcting points and a correction matrix are obtained; the three feature points, determined in simulation, on the robot are shot, and the coordinates of the three feature points relative to the industrial cameras are obtained; and homogeneous transformation in coordinate transformation is utilized, related data needed by correction is obtained, the data is transmitted to the computer, and the offline programming simulation of the industrial robot is corrected. The method is simple and easy to practice, and robot offline programming simulation is more precise and accurate.
