[0048] The working principle and usage process of the present utility model:

[0049] Under the control of the PLC system, the device moves the product to the screw locking station. The camera of the vision guiding mechanism 2 takes pictures of the product to find the screw hole position, monitors the position where the screw is about to be locked through the vision guiding mechanism 2, and then uses the screw conveying mechanism to lead the screw locking mechanism 1 to the target position. The screw feeder supplies the screw to the screw locking mechanism 1 under the control of the PLC system for screw locking. The process of screw locking is as follows:

[0050] Under the control of the PLC system, the output end of the second power component 19 extends. After the screw feeder delivers the screw to the position of the magnet 14, the magnet 14 attracts the screw. At this time, the third power component drives the first clamping body 1821 and the second clamping body 1822 to close. The top of the batch rod is in the fourth chamber, and the through hole 1823 clamps the screw, and the fixture adjusts the screw horizontally. The third power component drives the first clamping body 1821 and the second clamping body 1822 to open. The output end of the second power component 19 continues to extend to the target position for locking the screw, wakes up the magnet 14 to attract the batch rod to the screw cap. The second elastic body 16 plays a buffering role for the batch rod. The screw presses against the first power component 12, and the first elastic body 15 plays a buffering role. Finally, the first power component 11 drives the batch rod to rotate to lock the screw.

[0051] When the screw locking is completed, the batch rod retracts.

[0052] The above process is repeated for the next screw locking.
