A full-automatic biochemical analyzer, and a sampling device and a sampling method thereof. The sampling device comprises: a frame (100), a horizontal motion system, a vertical motion system, a sampling component and a force transmission guide rail (101). The horizontal motion system comprises a first stepping motor (116), the vertical motion system comprises a second stepping motor (103), and the first stepping motor (116) and the second stepping motor (103) are respectively fixedly mounted on the frame (100). The sampling component comprises a sampling needle pressing block (114) and a sampling needle (111). The stepping motors (116, 103) are both fixed on the frame. The analyzer is smart in motion, low in cost, and compact in structure, and meanwhile has the functions of open sampling and closed puncturing sampling and the function of conveying samples to the specified position. |
