[0025] The clamping and flipping mechanism includes a flipping motor 11, a clamping cylinder 12, and a fixture. The fixture includes a profiling plate 13 and a clamping plate 14. The flipping motor drives the profiling plate to rotate for positioning. The clamping plate is arranged on one side of the profiling plate, and the clamping cylinder is arranged under the profiling plate, and its output shaft drives the clamping plate to longitudinally slide to clamp the blood collection tube 50 on the profiling plate;

[0026] The cleaning mechanism uses an electrostatic cleaning box 21, which is arranged on one side of the clamping and flipping mechanism. The cleaning medium is deionized air. The air outlet of the electrostatic cleaning box is aligned with the tube orifice of the blood collection tube that has been flipped by a certain angle, and the foreign objects in the blood collection tube are blown and cleaned by the deionized air.

[0027] A tray mechanism is arranged below the clamp of the cleaning mechanism. The tray mechanism 30 includes a tray 31. When the clamp is flipped by a certain angle and releases the blood collection tube, the blood collection tube slides into the hole in the tray that fits the blood collection tube.

[0028] In this embodiment, the detection mechanism 40 is arranged above the tray and on the other side of the clamping and flipping mechanism. When the first row of holes in the tray is filled with the slipped blood collection tubes, the detection mechanism on it senses the situation of the tubes falling through the position sensor. The detection mechanism includes a position sensor, a bottom plate 42 with a pin shaft 44, and an induction piece 43. In this embodiment, the position sensor uses a groove type photoelectric switch 41. The bottom plate with the pin shaft is driven to move up and down by a cylinder 45, and the induction piece moves synchronously with the bottom plate with the pin shaft. The pin shaft is arranged opposite to the bottom of the inverted blood collection tube. When there is a tube inversion, the pin shaft is blocked downward and triggers the position sensor. The position sensor is electrically connected to the control end, and the control end is connected to the alarm.

[0029] In this embodiment, the profiling plate 13 is provided with a plurality of grooves that match the blood collection tubes. In this embodiment, two profiling plates arranged in parallel are used.

[0030] In this embodiment, a double - layer rubber - made clamping strip 15 is arranged on one side of the clamping plate 14, which does not damage the tube wall of the blood collection tube. The clamping cylinder uses a diaphragm cylinder. The diaphragm cylinder is used to drive the clamping plate to press down or lift up to clamp or release the blood collection tube. In this embodiment, the clamping area is set at the bottom of the blood collection tube. The blood collection tube is placed in the groove. When the clamp is in the horizontal position, the tube orifice faces the cleaning mechanism side.

[0031] In this embodiment, the output shaft of the flipping motor 11 is directly connected to the long shaft through a coupling in the axial direction of the output shaft. The long shaft is fixed to the profiling plate. An angle sensor 16 is also installed on the long shaft to detect the rotation angle of the long shaft.

[0032] In this embodiment, the electrostatic cleaning box 21 includes an inclined installation manifold 22.

[0035] In this embodiment, the sensing piece 43 is provided with two notches for mating with the groove-type photoelectric switch for sensing to meet the detection of blood collection tubes of different lengths.

[0036] In this embodiment, an optical fiber sensor 17 is arranged under the profiling plate 13 for detecting whether the blood collection tubes on the profiling plate slide off.

[0037] The working process of the present utility model is as follows:

[0038] The blood collection tubes can be placed in the grooves of the profiling plate manually or by an automatic gripper. After the blood collection tubes are clamped by the clamping and flipping mechanism, the clamping and flipping mechanism rotates counterclockwise by an angle, and the tube orifice of the blood collection tube is aligned with the electrostatic cleaning mechanism, and the electrostatic cleaning needle blows air to blow out the foreign matters in the tube; after the cleaning is completed, the clamping and flipping mechanism rotates clockwise by an angle, the tube orifice of the blood collection tube faces upward, the clamping and flipping mechanism is loosened, and the blood collection tubes fall into the tray tooling through the slideway and pass through the tube inversion detection mechanism until the tray tooling is full of blood collection tubes. The tray can be driven to accurately position and move until a tray is full.

[0039] In this embodiment, a cleaning device integrating a clamping and flipping mechanism, a detection mechanism and a tray mechanism is integrated on a frame body. Each mechanism is modularly installed on the frame body, with a compact structure, and effectively improves the cleaning efficiency of blood collection tubes.
