Problems solved by technology

[0003] There are many deficiencies in the liquid pipetting equipment at the current stage. For example, the integrated reagent transfer cannot be performed on the test tube with the test tube cap. ; Or, before and after each reagent transfer, disposable utensils such as suction pipes and suction nozzles need to be manually replaced, which is inconvenient to use, does not realize automatic control, and has low efficiency; and if the reagent solution is corrosive or other harmful to human skin, In frequent manual operations, it is even more detrimental to the safety guarantee of experimenters

Embodiment 1

[0039] The present invention provides a pipetting robot 100, the function of which is to transfer reagents in a test tube. see Figure 1-Figure 2 , the present invention provides a liquid pipetting robot 100, comprising: an equipment base 1, an electric control box 2, a mechanical arm 3, a pipetting device 4 and a pumping mechanism 11, the equipment base 1 is used for placing the pipetting components, so The electric control box 2 is connected with the mechanical arm 3, and one end of the mechanical arm 3 is connected with the pipetting device 4 and can drive the pipetting device 4 to move in the plane where it is located. A test tube rack 5, a pipette rack 6, a filter rack 7, a sample bottle rack 8 and a recovery rack 9 are also provided; test tubes are placed on the test tube rack 5, and the test tubes are filled with reagents, and the pipette rack 6 is placed with a test tube. A suction pipe, a filter head is placed on the filter rack 7 , and a sample bottle is placed on t...

Embodiment 2

[0049] The present invention also provides a liquid pipetting method, which is realized based on the above-mentioned liquid pipetting robot, and the liquid pipetting method includes:

[0050] S1, control the suction pipe loading and unloading mechanism to move to the suction pipe rack to install the suction pipe, and lift it to the highest position;

[0051] S2, controlling the cap-clamping mechanism to clamp the cap of the test tube and lift the test tube, and the rotating bottle-clamping mechanism to clamp the body of the test tube; the cap-clamping mechanism to unscrew the cap of the test tube;

[0052] S3, control the rotating bottle clamping mechanism to rotate the test tube to the bottom of the suction pipe loading and unloading mechanism, and the suction pipe descends to absorb the reagent;

[0053] S4. After the reagent suction is completed, screw the cap and put the test tube back into the corresponding test tube rack;

[0054] S5, control the suction pipe loading an...

Abstract

The invention provides a liquid transfer robot and a liquid transfer method, comprising an equipment base, an electric control box, a mechanical arm, a liquid transfer device and a pumping mechanism, the electric control box is connected with the mechanical arm, and one end of the mechanical arm is connected with a liquid transfer device The pipetting device includes a lifting mechanism, a cap-clamping and capping mechanism, a suction pipe loading and unloading mechanism and a rotating bottle-clamping mechanism, the lifting mechanism includes a lifting guide rail, and the cap-clamping and capping mechanism and the suction pipe loading and unloading mechanism are connected to the lifting guide rail and extend along the lifting guide rail. The lifting guide rail moves, the rotating bottle clamping mechanism is installed on the bottom surface of the lifting mechanism, and the pump mechanism and the suction pipe loading and unloading mechanism are connected by a guide hose. The liquid pipetting robot provided by the present invention is programmed and controlled precisely, saves labor costs, and improves pipetting efficiency, and the method proposed based on the liquid pipetting robot can realize cap screwing, reagent suction, reagent filtration, reagent transfer, and pipetting apparatus replacement, etc. The pipetting step also solves the problems that the reagent solvent is easily splashed to the operator and the safety is insufficient in the manual operation.

Description

technical field [0001] The invention belongs to the technical field of experimental equipment, and relates to a liquid transfer robot and a liquid transfer method, in particular to a robot and transfer method for transferring a reagent solution in a test tube. Background technique [0002] Accurate pipetting is required in a large number of clinical and laboratory experiments in the fields of biology, immunology, medicine, etc. to transfer various liquid reagents and / or samples into sample tubes for analysis or testing. [0003] The current pipetting equipment has many shortcomings. For example, the integrated reagent transfer cannot be carried out for the test tube with the test tube cover. Before the test tube transfer, the test tube needs to be manually removed, which is time-consuming and labor-intensive and wastes a lot of cost. ; Or, it is necessary to manually replace disposable utensils such as straws and nozzles before and after each reagent transfer, which is incon...
