In order to prevent the table 4 from touching the guide plate 7 during the tilting, a certain distance is present between the table 4 and the guide plate 7. However, when the working table 4 is turned over and the processed air inlet/outlet pipe is loosened, due to the distance between the working table 4 and the guide plate 7, the clamping block 411 contacts the guide plate 7 after the air inlet/outlet pipe is loosened and falls for a certain distance, so that the guide plate 7 can bear the force greater than the gravity of the air inlet/outlet pipe, and the influence on the guide plate 7 can be caused for a long time. The provision of the catcher pin 81 avoids this as much as possible. When the clamping block 411 loosens the air inlet and outlet pipe, the pneumatic mechanical claw 8 is still in a grabbing state, but due to the existence of the receiving rod 81 and the arrangement of the length, after the clamping block 411 loosens the air inlet and outlet pipe, the receiving rod 81 is displaced downwards due to the action of the pneumatic mechanical claw 8 and the gravity of the air inlet and outlet pipe, the lower end of the receiving rod 81 extends out of the workbench 4, when the pneumatic mechanical claw 8 on the side of the workbench 4 back to the base 11 is abutted against the pneumatic mechanical claw 8, the receiving rod 81 stops sliding downwards, the pneumatic mechanical claw 8 and the air inlet and outlet pipe are close to the guide plate 7, the pneumatic mechanical claw 8 loosens the air inlet and outlet pipe and drops onto the guide plate 7, and unnecessary burden on the guide plate 7 is reduced as much as possible.

As a modified specific embodiment, the side of the conveyor belt 2 facing away from the guide belt 5 is provided with a blocking plate 21 for preventing the finished air inlet/outlet pipe from being separated therefrom due to inertia. When the air inlet and outlet pipe finished by processing is conveyed to the conveying belt 2 by the guide belt 5, certain inertia exists when the air inlet and outlet pipe finished by processing enters the conveying belt 2 because the guide belt 5 is arranged obliquely, so that the air inlet and outlet pipe finished by processing can possibly fall out of the conveying belt 2, the barrier plate 21 is arranged to play a role of blocking the air inlet and outlet pipe finished by processing, and the air inlet and outlet pipe finished by processing is prevented from being separated from the conveying belt 2 under the action of inertia.

As a specific embodiment of the improvement, two limiting plates 62 are symmetrically arranged on the incoming belt 6, the two limiting plates 62 are arranged on two sides of the through hole 61 on the incoming belt 6, and when an external air inlet/outlet pipe is placed on the incoming belt 6, the limiting plates 62 are attached to the pipe wall of the air inlet/outlet pipe. When the outside business turn over trachea was placed and is passed into on the belt 6, the circumstances that the business turn over trachea took place the skew probably appears in the in-process of transmission for pneumatic telescopic link 921 can't be with business turn over trachea conveying to workstation 4 on, lead to the work on the workstation 4 to go on smoothly. The limiting plate 62 has a certain limiting effect on the air inlet and outlet pipe, and prevents the air inlet and outlet pipe from deviating on the belt 6.

In conclusion, the repeated overturning of the workbench 4, the repeated switching of the transit area 71 and the passage area 72 of the guide plate 7, the stopping and stopping of the conveying belt 6 and the expansion and contraction of the pneumatic telescopic rod 921 realize continuous conveying and processing of the air inlet and outlet pipe and conveying of the air inlet and outlet pipe for completing the processing, so that the whole working process is very smooth and efficient, and meanwhile, the help of an external manipulator is not needed, the occupied space of a workstation is greatly reduced, and the equipment cost is saved.
