Application example

Position detection for automated bolting

Cover

The task

After placing the battery modules in the housing bottom part, this step requires them to be screwed in place. The screw holes are usually located under mechanical devices, which in turn have an opening. The sensor is to be used to detect the position of the screw holes underneath.

The challenge

The reflection of the aluminum makes it difficult to detect the position of the covered holes. The high number of holes to be screwed increases the time required considerably.

Our solution

A VISOR® Robotic in the version with a narrow field of view precisely detects the drill holes at a sufficient distance. Thus, there is enough distance between the screwing system and the battery pack and damage is avoided. An optional ring light makes the inside of the hole appear darker and thus creates a clearer contour for position detection. Due to the high computing performance of the vision sensor, the position coordinates are available just a few milliseconds after image acquisition.

The vision sensor for robotics determines the exact position coordinates of the screw holes in a few milliseconds.

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
