Abstract: A system for establishing a junction trace of an assembly includes a surface model creating module, a processing module, and a material inspection module. The assembly includes a first part and a second part assembled with each other. The surface model creating module scans the first part and the second part to separately establish first surface model data and second surface model data. The processing module establishes assembled surface model data according to the first surface model data and the second surface model data, determines a junction region from the assembled surface model data, and determines inspection points mapped on the assembly according to the junction region. The material inspection module inspects materials of the assembly at the inspection points. The processing module establishes a junction trace of the first part and the second part in the assembly according to a material inspection result.

Abstract: A method for recognizing a deburring trajectory, relevant to be performed by a controller or a computer, includes the steps of: according to a process flow of a workpiece, analyzing a CAD file of the workpiece, determining a burr processing area and obtaining a mathematical model of boundary contour curve; applying a linear contour sensor to scan the workpiece to obtain contour section information of the workpiece; performing curve fitting upon the contour section information of the workpiece and the mathematical model of boundary contour curve so as to obtain a boundary curve function; and, utilizing the boundary curve function to determine deburring position information of the workpiece and to further generate a processing path. In addition, a system for recognizing a deburring trajectory is also provided.

Abstract: An automated calibration system for a workpiece coordinate frame of a robot includes a physical image sensor having a first image central axis, and a controller for controlling the physical image sensor adapted on a robot to rotate by an angle to set up a virtual image sensor having a second image central axis. The first and the second image central axes are intersected at an intersection point. The controller controls the robot to repeatedly move back and forth a characteristic point on the workpiece between these two axes until the characteristic point overlaps the intersection point. The controller records a calibration point including coordinates of joints of the robot, then the controller moves another characteristic point and repeats the foregoing movement to generate several other calibration points. According to the calibration points, the controller calculates relative coordinates of a virtual tool center point and the workpiece to the robot.
