  • Patent number: 11433541
    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.

  • Patent number: 11270427
    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.

  • Patent number: 10926414
    Abstract: A system for calibrating tool center point of robot is provided, which may include a first image sensor, a second image sensor, and a controller. The first image sensor may have a first image central axis. The second image sensor may have a second image central axis not parallel to the first image central axis, and intersect the first image central axis at an intersection point. The controller may control a robot to repeatedly move a tool center point thereof between the first and the second image central axis. The controller may record a calibration point including the coordinates of the joints of the robot when the tool center point overlaps the intersection point, and then move the tool center point and repeat the above steps to generate several calibration points, whereby the controller may calculate the coordinate of the tool center point according to the calibration points.
