The drag chain 6 is used to drive the grooves 10 to transmit the sample tube 11, which can avoid secondary rolling of the sample tube 11 during the transmission process. A support rod 7 is arranged on the top surface of the bottom plate 1, and a camera 8 is arranged on the top of the support rod 7. The camera 8 is located on one side of the material rack 5 provided with the drag chain 6, so that the camera 8 can collect image data of the sample tube 11 and rotate the circular hole on the surface of the sample tube 11 to the correct position without manual adjustment by the staff, thereby improving work efficiency and reducing the labor intensity of the staff. A reinforcement mechanism 9 is arranged on the top surface of the bottom plate 1; The reinforcement mechanism 9 includes two groups of fixed blocks 901 symmetrically arranged on the top surface of the bottom plate 1 and a reinforcement frame 904 arranged on the top surface of the material rack 5. The two groups of fixed blocks 901 are located between the two groups of material racks 5 and are symmetrically distributed on both sides of the cylinder 2 to facilitate the installation of the sleeve 902 and the long block 905. The top surface of one group of fixed blocks 901 is fixedly installed with a sleeve 902, and the interior of the sleeve 902 is slidably connected with a slide bar 903. The top of the slide bar 903 is fixedly installed with a cross bar 910, and the cross bar 910 is slidably connected to the reinforcement frame 904. The reinforcement frame 904 is located directly above the material rack 5. The bottom surface of the reinforcement frame 904 is provided with arc grooves 908, and the arc grooves 908 are evenly distributed on the bottom surface of the reinforcement frame 904.

[0021] Working principle: When in use, the entire transmission line uses the drag chain 6 to drive the groove 10 to drag the sample tube 11. After it moves to the alignment station, the cylinder 2 is activated to lift the top plate 3, and the top plate 3 drives the rotating wheel 4 to move. At the same time, the camera 8 starts to work, and the camera 8 is used to collect data on the outer surface of the punching area of ​​the sample tube 11 end, and identify the hole position. The servo motor drives the rotating wheel 4 to rotate the sample tube 11 to a suitable angle to ensure that the identified hole position is directly above. When the hole position is detected to be in the correct position, the rotating wheel 4 stops rotating, and the cylinder 2 falls immediately, completing the alignment process. When it is necessary to process insulation tubes of different specifications, the turntable 909 is manually rotated, and the turntable 909 drives the threaded rod 906 to rotate. The inside of the adjusting block 907 is threadedly connected to the threaded rod 906, so the threaded rod 906 drives the adjusting block 907 to move, and the adjusting block 907 drives the reinforcement frame 904 to move, and the reinforcement frame 904 then drives the slide bar 903 to slide inside the sleeve 902 until the arc groove 908 on the bottom surface of the reinforcement frame 904 is in contact with the surface of the insulation pipe. At this time, the reinforcement frame 904 can reinforce the insulation pipe to prevent the insulation pipe from falling off the material rack 5 during transportation. When the drag chain 6 drags the insulation pipe, since the insulation pipe is in contact with the arc groove 908, the insulation pipe drives the reinforcement frame 904 to move. At this time, relative sliding occurs between the reinforcement frame 904, the slide bar 903 and the adjusting block 907, thereby transporting the insulation pipe.
