[0050] The working process of the device of the present invention is as follows:

[0051] 1. First, put a certain number of sampling tubes into the screening bin mechanism 1, turn on the equipment and start working. The screening bin motor 111 drives the screening bin cam shaft 107 to rotate continuously through the screening bin coupling 110, and then drives the screening bin cam 108 to rotate, and then drives the screening bin bottom plate 101 to perform continuous vertical linear reciprocating motion under the joint limit of the linear bearing 104, the limit rod 103 and the short limit rod 105. Under the joint action of the vertical linear reciprocating motion of the screening bin bottom plate 101 and the screening bin block 113, the sampling tube realizes the preliminary posture adjustment and discharge of a large number of disordered sampling tubes.

[0052] 2. After being discharged from the screening bin mechanism 1 , the sampling tube enters the fixed slide 201 by virtue of the inclination angle of the fixed slide 201 and the gravity of the sampling tube itself.

[0053] 3. The sampling tube transition mechanism 2 starts working. The crankshaft motor 210 drives the moving connecting rod 206 to rotate through the crankshaft coupling 209, thereby driving the moving channel 202 to realize vertical linear reciprocating motion of the moving channel 202 under the joint limiting action of the moving channel slider 203 and the moving channel guide rail 204. The sampling tubes are then transported in batches of 15 to the groove above the moving channel 202 and then slide into the fixed channel 401 in the sampling tube rotation mechanism 4.

[0054] 4. The sampling tube rotating mechanism 4 starts to work. The drum motor 414 drives the sprocket shaft 409 and the large drum sprocket 408 to rotate through the large synchronous pulley 412 and the small synchronous pulley 411. The drum sprocket 405 is then driven to rotate through the matching drum chain 406, thereby rotating the rotating drum 402. The sampling tube slides to the top of the rotating drum 402 by its own gravity and the inclination angle above the fixed channel 401, and continues to rotate along its own axis.

[0055] 5. The barcode scanner 415 starts working and continuously reads and enters the barcode information of the sampling tube that is located above the rotating drum 402 and continuously rotates along its own axis.

[0056] 6. The sampling tube conveying mechanism 8 starts to work, and drives the small baffle 802 through the synchronous conveyor belt 801 to move the sampling tube above the rotating drum 402 to the area of ​​the abnormal sampling tube sorting mechanism 9.

[0057] 7. The abnormal sampling tube sorting mechanism 9 starts working. The abnormal horizontal linear module 901 can realize the horizontal movement of the abnormal vacuum suction cup 906 under the drive of the abnormal horizontal linear module motor 902. Similarly, under the action of the abnormal vertical linear module 903 and the abnormal vertical linear module motor 904, the abnormal vacuum suction cup 906 can realize the vertical movement. At the same time, the vacuum pump 3 works to provide suction for the abnormal vacuum suction cup 906. At the same time, combined with the reading result of the barcode scanner 415 and the collaborative judgment of the abnormal photoelectric switch 909 (if the barcode scanner 415 fails to successfully enter the sampling tube barcode information, and the abnormal photoelectric switch 909 recognizes that there is a sampling tube in the channel), the position of the abnormal sampling tube is judged, and then the abnormal sampling tube is transferred to the top of the abnormal disposal box 907. The vacuum pump 3 stops working, and the abnormal sampling tube falls into the abnormal disposal box 907.

[0058] 8. The sampling tube conveying mechanism 8 starts to work, and drives the small baffle 802 through the synchronous conveyor belt 801 to convey the normal sampling tubes into the sampling tube turning mechanism 5.

[0059] 9. Under the conveying action of the sampling tube conveying mechanism 8, the sampling tube slides onto the sampling tube flip slide 501. By setting the distance between the sampling tube flip slides 501 to be greater than the diameter of the sampling tube body and smaller than the diameter of the sampling tube cap, the sampling tube relies on its own gravity on the sampling tube flip slide 501 to achieve a posture with the sampling tube cap facing upward, providing the necessary conditions for subsequent suction and transfer. At the same time, the positioning photoelectric switch 504 can identify whether there is a sampling tube in each sampling tube flip slide 501.

[0060] 10. The sampling tube transfer mechanism 6 starts to work. Under the action of the sampling tube horizontal transfer linear module 601 and the sampling tube horizontal transfer linear module motor 603, the sampling tube variable distance suction mechanism 7 is horizontally moved. Under the action of the sampling tube vertical transfer linear module 602 and the sampling tube vertical transfer linear module motor 604, the sampling tube variable distance suction mechanism 7 is vertically moved.

[0061] 11. The sampling tube variable distance suction mechanism 7 starts to work, and the electric push rod 702 drives the electric push rod connecting piece 703 and the variable distance guide groove connecting piece 705 to reciprocate linearly, thereby driving the variable distance guide groove plate 706 to reciprocate linearly, thereby making the variable distance roller 712 follow the guide groove on the variable distance guide groove plate 706. Under the joint action of the variable distance horizontal slider 710, the variable distance horizontal guide rail 707 and the variable distance vertical guide rail and slider 709, the distance of the variable distance suction cup 713 is changed. By setting the extension and retraction of the electric push rod 702, the distance between the variable distance suction cup 713 and the sampling tube turning slide 501 is achieved to be the same. The vacuum pump 3 works to suck the sampling tube with the tube cap facing upward on the sampling tube turning slide 501, and transfers it to the predetermined position under the action of the above-mentioned sampling tube transfer mechanism 6. The vacuum pump 3 stops working, and the sampling tube falls into the sampling tube storage container by gravity, completing the sorting of the sampling tube.
