(3) the sample rack objective table 5 is driven by the objective table motion assembly to move to a sample code scanning position, a bar code of the sample cup 101 is scanned by the sample code scanner 1201, an information adding frame is popped up, and after information is input, the information is clicked and submitted;

(4) the reagent card bar scanner 1202 scans the bar code of the reagent card bar 17 and uploads the bar code to the upper computer;

(5) after the upper computer confirms that the reagent card strip 17 is correct, diluting and uniformly mixing the sample in the sample cup 101 in the sample rack 1 by the sample adding device through the puncture sampling needle 2, and adding the diluted and uniformly mixed sample into the reagent card strip 17; the sample adding device separates the reagent card strip 17 from the sample rack 1;

(6) the sample rack 1 is lowered and pushed to the disposal platform 11, and the reagent card strip 17 is moved to the carrying device 7 and then carried to the sample inlet of the adaptive detection instrument.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
