[0033] The discharging end of the feeding rack 2 is provided with a waiting position. The pipe fittings 8 are discharged one by one from the feeding rack 2, and the discharged pipe fittings 8 fall onto the waiting position.

[0034] The discharging end of the feeding rack 2 is provided with a first guide rail 2-8. On both sides of the waiting position, a detection component 4 and a positioning and rotating component 3 are respectively provided. The positioning and rotating component 3 is installed on the first guide rail 2-8 and can move along the first guide rail 2-8. The positioning and rotating component 3 is used to drive the pipe fitting 8 to move or drive the pipe fitting 8 to rotate around its own central axis. The detection component 4 is used to perform visual detection on one end of the pipe fitting 8.

The material transporting member 6 is used to transfer the pipe fittings 8 on the turnover cart member 1 to the loading rack 2.

[0050] An exhaust pipe loading method includes the following specific steps:

[0051] Step 1: The pipe fittings 8 are discharged one by one from the loading rack 2, and after the pipe fittings 8 are discharged, they fall onto the waiting material position.

[0052] Step 2: The two jaws 3-10a on the rotary clamp 3-10 are in the open state. The servo motor 3-4 drives the sliding seat 3-1 to move from the initial position. The sliding seat 3-1 moves along the first guide rail 2-8 and towards the direction close to the detection member 4. One end of the pipe fitting 8 abuts against the first end positioning plate 3-10b on the rotary clamp 3-10, and the other end of the pipe fitting 8 moves towards the direction of the vision detection camera 4-2 until it abuts against the second end positioning plate 4-4 in front of the vision detection camera 4-2. Then the sliding seat 3-1 continues to move. At this time, a relative movement occurs between the mounting base 3-3 and the sliding seat 3-1. When the sensing piece 3-12 on the mounting base 3-3 moves to the position directly opposite to the first proximity switch 3-11 on the sliding seat 3-1, the first proximity switch 3-11 is triggered. The first proximity switch 3-11 transmits a trigger signal to the control system, and the control system controls the servo motor 3-4 to stop running. The length of the pipe fitting 8 is judged by the feedback of the moving distance of the servo motor 3-4. If the length of the pipe fitting 8 is detected to be qualified, the next step is carried out. If the length of the pipe fitting 8 is detected to be unqualified, the material picking member 7 picks up the pipe fitting 8 with unqualified length and puts it into the unqualified box.

[0053] Step 3: Position the gripper 3-10a on the rotating component 3 to clamp one end of the pipe fitting 8, drive the pipe fitting 8 to rotate 360 degrees around its own central axis through the horizontal rotation motor 3-8, and perform visual inspection on one end of the pipe fitting 8 through the vision inspection camera 4-2; if the visual inspection is qualified, the material taking component 7 takes away the pipe fitting 8 and sends it to the processing equipment; if the visual inspection is unqualified, the material taking component 7 takes away the pipe fitting 8 and puts it into the unqualified box.
