The image capturing device 700 is located above the storage bin 400, and its lens faces the two driving rollers 520 of the rolling mechanism 500.

As shown in fig. 6 and 7, the transfer mechanism 800 is configured to move the blood collection tubes on the rolling mechanism 500 to the narrow belt conveyor 900; the transfer mechanism 800 may adopt various known structures to move the blood collection tubes from the rolling mechanism 500 to the narrow belt conveyor 900. However, since the rolling mechanism 500 is located in the storage chamber 400, the space in the storage chamber 400 is limited, and it is difficult to install the complicated transfer mechanism 800. In this embodiment, the blood collection tube is automatically dropped and transferred by connecting the two driving rollers 520 of the rolling mechanism 500 to the transfer mechanism 800, and driving the two driving rollers 520 to reciprocate and translate in a direction perpendicular to the axes of the two driving rollers 520, so as to adjust the distance between the two driving rollers 520.

As shown in fig. 7-9, the top surface of the driving disk 820 forms an oval driving groove 821, two opposite rolling members 850 are disposed in the driving groove 821, the rolling members 850 may be a driving wheel, such as a bearing, and the driving wheel is disposed in the driving groove 821 in a rolling manner, and has an outer diameter corresponding to the width of the driving groove 821, although the rolling members 850 may also be a cylinder, and each rolling member 850 is connected to a roller frame 510 where the driving roller 520 is located, specifically, to the bottom of an upright plate of the roller frame.

As shown in fig. 7, the roller frame 510 is movably disposed on a fixed guide 860, and specifically, a shaft sleeve 870 whose axis is perpendicular to the vertical plate 511 is disposed on the vertical plate 511 of the two roller frames 510, and the shaft sleeve 870 is sleeved on the fixed guide 860, so that the two vertical plates 511 can slide back and forth along the guide 860, and the guide 860 can be fixed on the mounting base 840 and can keep the roller frame 510 spaced from the support. The guide rails 860 may be fixed to side plates of the narrow belt conveyor 900, so that the two roller frames 510 are slidably disposed on the two guide rails 860.

When the driving motor 810 drives the driving disc 820 to rotate, the two roller frames 510 are driven to synchronously move towards and away from each other, as shown in fig. 8, when the distance between the two driving rollers 520 is the largest, the two rollers correspond to two ends of the long axis of the oval driving groove 821. As shown in fig. 9, when the distance between the two driving rollers 520 is the smallest, the two driving rollers 520 correspond to the positions of both ends of the minor axis of the elliptical driving groove 821. The structure can realize the synchronous movement of the two roller frames 510 through one driving motor 810, thereby improving the opening and closing efficiency and being beneficial to improving the sorting beat, and the motor only needs to work in one direction, so that the control is simpler.

During operation, the transfer mechanism 800 makes the distance between the two driving rollers 520 smaller than the outer diameter of the tube body of the blood collection tube, the blood collection tube falls between the two driving rollers 520, when the driving rollers 520 rotate, the blood collection tube rotates along with the driving rollers 520, the image collection device 700 above the driving rollers 520 collects the image of the blood collection tube, so that the color of the tube cap of the blood collection tube and the sorting route are determined, after the route is determined, the transfer mechanism 800 drives the distance between the two driving rollers 520 to be adjusted to be larger than the outer diameter of the tube cap of the blood collection tube (the outer diameter of the tube cap is larger than the outer diameter of the tube body), and the blood collection tube can fall on the narrow-band conveyor 900 below the two driving rollers 520 to be conveyed and sorted.
