As a common operating instrument in laboratory, pipette suction has huge consumption and high hygienic requirement. Because the suction head is more precise and easy to damage, in order to facilitate the replacement of the suction head or to achieve the purpose of asepsis during the experimental operation, the suction head needs to be placed in the suction box before use. Now the packaging form of the domestic pipette suction head is mostly in bags, so it needs to be manually inserted into the suction box by the staff. This packaging method is not only low production efficiency, but also low production efficiency. The speed of arrangement and packing is slow, and the use of manual arrangement will also cause secondary pollution of pipette suction head.

Therefore, the arrangement and packing of pipette heads by manual can not meet the production demand and hygiene requirements of existing medical sites and laboratories. At present, there is a gap in the automatic packaging and packing equipment, and it is urgent to form an automatic loading system with a certain capacity for laboratory scientific research to improve the efficiency and accuracy of the nozzle packing and reduce the labor intensity of the nozzle packing personnel.
