Abstract
An automated grasping apparatus for precise and clean assembly of a large-aperture optical element includes a reconfigurable end effector, a manipulating robot arm, a computer control unit, a task management software and process database system, a code scanning recognizer, and an electrical auxiliary support system. During an assembling operation, a code of the optical element is scanned by the code scanning recognizer, wherein a suitable process for the optical element is retrieved automatically. The configuration of the end effector is adjusted according to an instruction flow that precision grasping and stable suction of the optical element are achieved by manipulating the end effector. The robot arm is moved to place the optical element at a designated station, and the robot arm carries the end effector to return to an original position after the assembly operation is completed.
