Abstract

The invention relates to a device for estimating the absolute positioning accuracy of an industrial robot. The device comprises a standard workpiece fixed at a certain position in the working space ofa robot and a standard tool, wherein the standard workpiece comprises a workpiece tip point; the standard tool comprises a tool base arranged on a flange disc at the tail end of the robot and a tooltip point, and the tool tip point and the tool base are of an integrated molding structure. The method comprises the following steps of: adopting a robot demonstrator to teach a robot and lead the tool tip point to contact with the workpiece tip point of the standard workpiece by different postures, acquiring a position coordinate of the tool tip point in a robot base coordinate system, and continuously acquiring the position coordinate value to realize estimation on the absolute positioning accuracy of the robot. The device is simple in structure and operation, an operator can finish estimation on the absolute positioning accuracy of the industrial robot quickly, the cost is low, the device is applicable to various large manufacturers and can carry out personalized customization for different types of industrial robots from different manufacturers.

Description

technical field [0001] The invention relates to the technical field of industrial robot application, in particular to a device and method for estimating the absolute positioning accuracy of an industrial robot. Background technique [0002] Industrial robots are widely used in complex operations such as assembly, handling, welding, spraying, and laser cutting. On the one hand, they can improve work quality and efficiency, and on the other hand, they can protect human body safety. The reduction of production cost is also of great significance. With the diversification and complexity of industrial robots' working methods, the precision requirements of robots in the industrial field are becoming higher and higher. The accuracy of the robot mainly includes repeated positioning accuracy and absolute positioning accuracy. Repeated positioning accuracy refers to the degree of consistency of the actual position after repeating the same command pose from the same direction several t...
