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, which is used to transfer reagents in test tubes. 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 liquid pipetting device 4, and a pump mechanism 11, the equipment base 1 is used to place a pipetting assembly, and the The electric control box 2 is connected with the mechanical arm 3, and one end of the mechanical arm 3 is connected with the liquid pipetting device 4 and can drive the liquid pipetting device 4 to move in the plane where the device base 1 is located. Also be provided with test tube holder 5, suction pipe holder 6, filter holder 7, sampling bottle holder 8 and recovery rack 9; Place test tube on the described test tube holder 5, contain reagent in the described test tube, be placed on the described suction pipe holder 6 A suction pipe, a filter head is placed on the filter rack 7, and...

Embodiment 2

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

[0050] S1. Control the straw loading and unloading mechanism to move to the straw rack to install the straw, and raise it to the highest position;

[0051] S2. Control the clamping cap screwing mechanism to clamp the test tube cover and lift the test tube, and the rotating bottle clamping mechanism clamps the test tube body; the clamping cap screwing mechanism unscrews the test tube cover;

[0052] S3. Control the rotating clamping mechanism to rotate the test tube to the bottom of the straw loading and unloading mechanism, and the straw is lowered 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 and unloading mechanism to the filter frame to install ...

Abstract

The invention provides a pipetting robot and a pipetting method, the pipetting robot comprises an equipment base, an electric control box, a mechanical arm, a pipetting 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 the pipetting device; the pipetting device comprises a lifting mechanism, a cover clamping and screwing mechanism, a straw loading and unloading mechanism and a rotary bottle clamping mechanism, the lifting mechanism comprises a lifting guide rail, the cover clamping and screwing mechanism and the straw loading and unloading mechanism are connected to the lifting guide rail and move along the lifting guide rail, and the rotary bottle clamping mechanism is installed on the bottomface of the lifting mechanism. And the pumping mechanism is connected with the straw loading and unloading mechanism through a flow guide hose. The pipetting robot provided by the invention is programmed and accurately controlled, the labor cost is saved, the pipetting efficiency is improved, and the pipetting steps such as cap screwing, reagent sucking, reagent filtering, reagent transferring andpipetting appliance replacing can be realized on the basis of the method provided by the pipetting robot; meanwhile, the problems that in manual operation, reagents and solvents are prone to splashing to injure operators, and safety is insufficient are solved.

Description

technical field [0001] The invention belongs to the technical field of experimental equipment, and relates to a liquid pipetting robot and a liquid pipetting method, in particular to a robot and a liquid pipetting method for transferring a reagent solution in a test tube. Background technique [0002] In a large number of clinical experiments and laboratory experiments in the fields of biology, immunology, medicine, etc., accurate pipetting operations are required to transfer various liquid reagents and / or samples into sample tubes for analysis or testing. [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 carrying out 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 ...
