A sealed cavity is formed between the guide block, the third driving mechanism and the inner wall of the guide hole. An air passage is formed in the guide block. The shaft hole of the hollow shaft is connected to the sealed cavity through the air passage. The suction nozzle is connected to the sealed cavity. The third drive mechanism includes a cylinder body, in which a piston chamber is formed to accommodate a piston head. The nozzle is connected to the piston head. A third adapter module is provided on the second main body. The third adapter module has a fifth air passage that is connected to an external positive pressure device. The third adapter module is connected to the piston chamber through a third channel. The fluid output by the external positive pressure device enters the piston chamber through the fifth air passage and the third channel to drive the piston head to move, so that the piston head drives the nozzle to move up and down.

2. The screw fastening mechanism according to claim 1, characterized in that, The first main body is provided with a second adapter module. The second adapter module has a third air passage connected to an external positive pressure device and a fourth air passage connected to the atmosphere. The second adapter module is connected to the second air passage through a second channel.

3. The screw fastening mechanism according to claim 1, characterized in that, A positive pressure main chamber is formed inside the second main body. The positive pressure main chamber is connected to an external positive pressure device. The fifth air passage is connected to the positive pressure main chamber. The piston head divides the piston chamber into an inner chamber and a driving chamber. The inner chamber is located below the driving chamber and is connected to the atmosphere. A pressure spring is provided in the inner chamber to make the piston head always have an upward tendency. The driving chamber is connected to the positive pressure main chamber.

4. A functional head, characterized in that, It includes the screw fastening mechanism as described in any one of claims 1-3, a base, and a second drive mechanism disposed on the base, wherein the second drive mechanism drives the fastening body to move up and down.

5. An intelligent platform system, characterized in that, Includes the functional header as described in claim 4.

6. A screw fastening method, characterized in that, The screw fastening method employs the screw fastening mechanism described in claim 3, and the screw fastening method comprises the following steps: Step 1: Connect the hollow shaft's shaft hole to the first channel on the first adapter module; Connect the second channel on the second adapter module to the second air passage on the first adapter module; Connect the first air passage on the first adapter module to an external negative pressure device; Connect the third air passage on the second adapter module to an external positive pressure device; Connect the fifth air passage on the third adapter module to an external positive pressure device; Step 2: Open the first and fifth air passages and close the second air passage to create a negative pressure inside the nozzle, allowing the nozzle to pick up the screw; Step 3: Open the second and third air passages, close the first and fifth air passages, so that a positive pressure is formed inside the nozzle, the vacuum inside the nozzle is broken, and the hollow shaft is driven to move simultaneously by the first drive mechanism and the rotary drive mechanism, so that the screwdriver bit attaches the screw to the product. Step 4: Open the second and fourth air passages, close the first and third air passages, so that the inside of the nozzle is at normal pressure, and stop the rotary drive mechanism from working. The first drive mechanism drives the hollow shaft to move upward, and the bit moves up to reset. Step 5: Repeat steps 2 to 4, and use the screwdriver bit to attach screws to the product in a cyclical manner.
