Coordinate system correction method, device and electronic equipment of robot workpiece

Abstract

The invention provides a robot workpiece coordinate system correction method and device and electronic equipment, and relates to the technical field of workpiece correction. The method includes: controlling a robot workpiece to move according to a preset trajectory; Detecting a plurality of positions of the tool optical target in the movement process of the robot workpiece and the position of thereference optical target; Respectively determining the position coordinates of the tool optical target under the current workpiece coordinate system and the position coordinates of the reference optical target under the current workpiece coordinate system; carrying out Position change processing on the current workpiece coordinate system, so that the position coordinates of the tool optical targetunder the current workpiece coordinate system after position change are matched with preset reference position coordinates; Determining deviation data of the current workpiece coordinate system and the reference workpiece coordinate system; And correcting the position of the robot workpiece. The coordinate system of the robot workpiece can be quickly corrected in an automatic mode, and the correction precision of the coordinate system of the workpiece is improved.

Description

technical field [0001] The invention relates to the technical field of workpiece correction, in particular to a coordinate system correction method, device and electronic equipment of a robot workpiece. Background technique [0002] At this stage, the automobile industry plays a decisive role in the economic development of our country. As one of the four major parts of the automobile, the body technology has high requirements. Among the various body technology, the welding process is the most important processing technology, and the welding quality directly affect the quality of the vehicle. Under the premise of large-scale assembly line production, various reasons may cause deviations in the welding position of the robot. Once a position deviation occurs, if it cannot be quickly eliminated, a large number of defective products will be produced or production will be stopped for a long time. In reality, the calibration method of the workpiece coordinate system that is often ...

Problems solved by technology

Under the premise of large-scale assembly line production, various reasons may lead to deviations in the welding position of the robot. Once a position deviation occurs, if it cannot be quickly eliminated, a large number of defective products will be produced or production will be stopped for a long time.

However, in reality, the calibration method of the workpiece coordinate system often used in the factory production line still requires manual calibration, which is time-consuming and labor-intensive with large errors.
