Description

Technical Field

[0001] The present invention relates to the technical field of biological science experimental equipment manufacturing, and more particularly to a desktop-level pipette tip boxing machine. Background Art

[0002] Pipettes are widely used in fields such as biological sciences, medicine, and chemistry for quantitatively transferring liquids. Pipette tips are also widely used in molecular biology and genetics research. To meet laboratory needs, tips are often packaged in boxes and removed individually with a pipette.

[0003] However, in order to reduce experimental costs, laboratories currently purchase domestic pipette tips that are mostly bagged. Existing pipette tip boxing machines, on the one hand, have a low degree of automation and do not fundamentally solve the waste of manpower and time; on the other hand, they are large in size and mostly use vibration plates for feeding, which makes loud noises and is not suitable for scientific research laboratory environments.

[0004] Therefore, providing a fully automatic desktop pipette tip boxing machine is a problem that those skilled in the art urgently need to solve. Summary of the Invention

[0005] In view of this, the present invention provides a desktop pipette tip cartoning machine with a high degree of automation, improved cartoning efficiency, small size, low noise, and suitable for scientific research laboratory environments.

[0010] The suction head box moving platform assembly is slidably mounted on the upper portion of the base, and the suction head box moving platform assembly corresponds to the bottom of the feeding assembly.

[0011] By adopting the above scheme, the beneficial effects of the present invention are:

[0012] The tip enters the feeding assembly from the hopper, enters the feeding assembly under the action of the tip conveying assembly, and finally enters the tip box moving platform assembly to complete the box loading. The entire process does not require manual operation and has a high degree of automation, which improves the box loading efficiency. At the same time, the entire mechanism occupies a small volume and generates less noise, making it suitable for scientific research laboratory environments.

[0013] Furthermore, the feeding assembly includes a carrying plate, a feeding wheel, a gear ring, a first motor and a gear.

[0014] The supporting plate is vertically fixed inside the shell; a feeding through hole is provided in the middle of the supporting plate;
