Abstract
This invention provides a system and method for the automatic assembly of screws on large antenna arrays. The system includes an assembly mechanism, which includes an end effector; a linear motion mechanism, on which the assembly mechanism is mounted and moves along a first horizontal direction under the drive of the linear motion mechanism; a lifting mechanism, disposed on one side of the linear motion mechanism along a second horizontal direction; the antenna array can move vertically under the drive of the lifting mechanism; a vision mechanism, fixed to the end effector, for acquiring feature images of screw holes on the antenna array; and a control unit, electrically connected to the linear motion mechanism, the lifting mechanism, the assembly mechanism, and the vision mechanism. The control unit controls the linear motion mechanism and the lifting mechanism to adjust the relative position of the end effector and the screw holes on the large antenna array, and completes the precise alignment of the end effector and the screw holes based on the feature images of the screw holes acquired by the vision mechanism, so that the end effector completes the screw tightening assembly.
