The base of a battery pack is the housing bottom part, which is first removed from a material container by a gantry or articulated-arm robot. For his purpose, it is necessary to determine the position of the component without contact.
The housing bottom parts are transported to the removal station in material containers, resulting in a certain position inaccuracy of the components. For a precise gripping process, sensors determine the exact position of the housing bottom parts. The size of such housing bottom parts adds to the difficulty - even small mismeasurements can cause damage to the robot gripper or the component.
With the VISOR® Robotic, the exact position of the housing bottom parts is determined and transmitted to the controller in robot coordinates. Due to the compact and robust design of the VISOR®, it can be integrated into the robot gripper. With the help of standardized calibration plates, the image coordinates can be converted into world coordinates. Due to the size of the battery modules, 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 a reliable gripping process.
