Automatic processing device for liquid samples

An automatic processing device for liquid samples, comprising:

• a sample region, configured to accommodate a plurality of centrifuge tubes;
• a control module, comprising a mechanical module,
• wherein the mechanical module comprises:
• a liquid drawing/discharging machine configured to draw liquid from the centrifuge tubes or discharge liquid to the centrifuge tubes, wherein the liquid drawing/discharging machine comprises;
• a roller, the roller having a first end and a second end opposite to each other, and a plurality of grooves spirally along the longitudinal axis of the roller;
• and
• a plurality of micropipettes operatively coupled to the plurality of grooves, wherein rotating the roller causes the micropipettes to move laterally in respect to the direction of the grooves;
• an image identification device coupled to the control module;
• and
• a centrifuge coupled to the control module, wherein the centrifuge is configured to accommodate the centrifuge tubes and perform a centrifugal treatment.
