Application example

Setting down the housing top for final assembly


The task

After determining the position of the housing top in the material carrier, the component is now placed on the housing bottom part.

The challenge

For precise placement, the sensor must determine the exact position of the hole coordinates, which can be located under seals, in the housing bottom part. The size of such housing tops adds to the difficulty - even small incorrect measurements can cause damage to the robot gripper or the component.

Our solution

With the VISOR® Robotic in the variant with a narrow field of view, the exact position of the hole positions in the housing bottom part is determined and transmitted to the controller in robot coordinates. The compact and robust design of the vision sensor allows it to be integrated into the robot gripper, making efficient use of the resolution and enabling precise and smooth placement of the upper part on the lower part. With the hand-eye calibration included in the VISOR®, it communicates directly in robot coordinates. In addition, the contour detector provides position control and thus provides additional information for safe placement of the module besides the position coordinates. Due to the size of the housing top parts, the X/Y coordinates are determined on the basis of two component features, which are then calculated into a central object coordinate. This results in high accuracy for reliable placement. An optional ring light makes the inside of the hole appear darker, creating a clearer contour for position determination.

Your advantages

  • Thanks to the fully automatable hand-eye calibration, the VISOR® always provides real X/Y and angle information, without time-consuming back-calculation on the robot controller
  • With its high computing performance in a compact design, the VISOR® hardware is predestined for use directly on the robot gripper
  • Reduced cabling effort due to e.g. AIDA-compliant, robot-compatible push-pull cables
  • The VISOR® software offers various functions for determining the position of components
  • Easy connection to robotics systems of leading manufacturers with functions such as:
    • Automated calibration to the robot coordinate system
    • Automated validation of position data
    • Standardized coordinate transmission
