The gantry mechanism, the screw locking machine 1, the height gauge 2 and the camera 3 are electrically connected to the control mechanism. When in use, the gantry mechanism drives the screw locking machine 1, the altimeter 2 and the camera 3 to move above the product. The altimeter 2 detects the distance between itself and the product and transmits the data to the control mechanism. Since the distance between the altimeter 2 and the screw locking machine 1 is known, the control mechanism can calculate the distance between the screw locking machine 1 and the product. The control mechanism controls the gantry mechanism to lock the screws of the screw locking machine 1 accurately close to the product according to the distance information between the screw locking machine 1 and the product. After the screw locking machine 1 tightens the screw, the camera 3 takes a photo of the screw for detection.
