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.
