[0044] The working principle of the utility model is as follows: a plurality of P-Xa pipes 13 with the same diameter are placed on the material placing trough 105, and the vibrating body 103 is started. Two of the P-Xa pipes 13 are respectively transported along the feeding trough 104 to the two arc grooves 107 of the first limit plate 106 under the vibration of the vibrating body 103, and then the second cylinder 403 is started. The sliding plate 401 slides above the through port 204 under the push-pull action of the second cylinder 403, and the first cylinder 301 moves with the sliding of the sliding plate 401, and the first cylinder 301 moves with the sliding of the sliding plate 401. The connected adsorbent 502 also moves with it. When the adsorbent 502 moves to the top of the arc groove 107, the first cylinder 301 is started. The first cylinder 301 lowers the adsorbent 502 to a position close to the pipe 13 and then starts the three-axis cylinder 501. While the three-axis cylinder 501 adjusts the height of the adsorbent 502 to the surface of the pipe 13, the three-axis cylinder 501 takes in air through the air inlet 5011 to generate negative pressure in the negative pressure frame. The negative pressure passes through the air guide hole and the adsorption hole in turn to reach the outlet of the adsorbent 502. The adsorbent 502 is in the negative pressure frame. The pipe 13 is adsorbed and fixed under the action of pressure, and the first cylinder 301 is started again, so that the fixed circular ring 12 and the pipe 13 rise to a certain position, and then the second cylinder 403 is started. The sliding plate 401 slides above the opening 204 toward the conveying workbench 7 under the pushing action of the second cylinder 403, until the sliding plate 401 moves the adsorption member 502 and the pipe 13 to the top of the fixed circular ring 12, and the first cylinder 301 is started. The first cylinder 301 lowers the fixed circular ring 12 and the pipe 13 to the fixed circular ring 12. Near the top, the pipe 13 is lowered to the top of the fixed circular ring 12 under the drive of the three-axis cylinder 501. At the same time, the air inlet of the three-axis cylinder 501 no longer takes in air, so that no negative pressure is generated in the negative pressure frame, and the adsorption component 502 no longer adsorbs the pipe 13, and the pipe 13 falls and is sleeved on the fixed circular ring 12. Then the motor is started, and the conveying workbench 7 rotates around the center under the drive of the motor and the commutation action of the right-angle commutator 901, and the pipe 13 on the fixed circular ring 12 is rotated onto the processing device, thereby realizing the loading of the pipe 13.
[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
