At the same time, the test tube cap identification sensor 6 works to identify the position of the rotating manipulator 10. When the rotating manipulator 10 moves to the preset position, the screw motor 3 stops, and the rotating manipulator 10 drives the rotating claw 11 to start rotating, and rotates the test tube cap to the disengaged position, and the screw motor 3 drives the rotating manipulator 10 on the installation cylinder 4 to drive the rotating The test tube cap on the clamp 11 moves to the side away from the blood test tube. After the cap is removed, the blood test tube is transported to the blood collection area for sampling. After sampling, it returns to the cap removal and capping position, and the screw motor 3 drives the installation cylinder 4 to move. The installation cylinder 4 drives the rotating manipulator 10 to move toward the side close to the blood test tube.
