[0015] Compared with the prior art, the present invention has the following beneficial effects: 1.

The air output of the air outlet becomes smaller while the air intake of the air inlet remains unchanged, so that the gas pushed out by the cylinder will first fill the communication cavity and then be discharged from the air outlet. Thus, a buffer air cavity will be formed in the communication cavity to achieve buffering, and it can be externally connected, and the maintenance and replacement are convenient.

[0016] 2. For a cylinder buffer mechanism of the present invention, during production, the buffer seat is transported by the first transfer device and placed on the clamping and transfer device.

Then, the clamping and transfer device continuously transports the buffer seat through the second assembly device and the locking device in sequence for full-automatic assembly to improve production efficiency.

[0017] 3. For a cylinder buffer mechanism of the present invention, when grasping the sealing ring, first, the first lifting driver drives the rotating driver to drive the mounting base, two mounting disks and two sets of telescopic grasping members into the storage bucket. Then, the upper telescopic grasping member first grasps the first sealing ring, that is, the telescopic cylinder pushes the rotating wheel to abut against the inner wall of the sealing ring, and then the vacuum suction pump cooperates with the air duct to make the rotating wheel adsorb the inner wall of the sealing ring. Then, the telescopic cylinder drives the rotating wheel to reset. Then, the first lifting driver rises, so that the lower telescopic grasping member corresponds to the position of the topmost sealing ring, and thus grasps the sealing ring, and drives it to move through the first lead screw driver and places it on the buffer seat. Then, the first lifting driver drives it to descend, so that the sealing rings grasped by the two sets of telescopic grasping members are placed in the buffer cavity. The telescopic cylinder pushes the rotating wheel to drive the sealing ring into the sealing groove in the buffer cavity. Then, the rotating driver drives the mounting base to rotate, so that the rotating wheel rotates along the inner wall of the sealing ring to completely push the sealing ring into the sealing groove, realizing the full-automatic assembly of the sealing ring.

[0018] 4. For a cylinder buffer mechanism of the present invention, when grasping the sealing ring and when it is to be locked, the screws are transported onto the screw transport frame, and then are respectively moved onto the four screw placement frames through vibration. First, the third conveyor transports the locking cover plate, and the fourth lead screw driver drives the double-end lifting driver to drive the second vacuum adsorption plate above the locking cover plate and grasp the locking cover plate, and cooperates with the fourth lead screw driver to place the cover plate on the buffer seat. Then, the fourth lead screw driver drives the double-end lifting driver to drive the rodless cylinder above the buffer seat, and drives the bolt locking member to move above the four screw placement frames through the rodless cylinder, and the four screwdrivers are respectively aligned with the screws on the four screw placement frames. Then, the third lifting driver drives the rodless cylinder to drive the four screwdrivers to descend to contact the screws, and the screwdriver heads are placed in the tightening grooves of the screws by rotating the tightening motor. Then, the electromagnetic generating member is activated to make the screwdriver magnetically attract its screw, and then the rodless cylinder drives the bolt locking member to move above the buffer seat. Then, the third lifting driver drives the rodless cylinder to drive the four screwdrivers to descend and cooperate with the rotation of the tightening motor to lock the screws on the buffer seat, so that the locking cover plate is stably covered on the buffer seat. Then, the fourth lead screw driver drives the double-end lifting driver to drive the second vacuum adsorption plate onto the buffer seat to grasp the buffer seat and transport it onto the conveyor frame, and is transported through the conveyor frame to realize automatic locking.
