[0020] Figure 1 It is a schematic diagram of the overall structure of the utility model;

[0021] Figure 2 It is a cross-sectional schematic diagram of the constant contact flipping device of the utility model;

[0022] Figure 3 This is a state diagram of the implementation of the constant contact flipping device of the utility model. DETAILED DESCRIPTION

[0023] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1 The cryotube sorting device shown includes a hopper device 1, a sliding and flipping device 2 and a storage device 3.

[0025] The hopper device 1 comprises:

[0026] The hopper body 1-1 is penetrated from top to bottom and its inner diameter gradually decreases from top to bottom. The freezing tubes 4 are put in from the top and fall out from the bottom in sequence. The hopper body 1-1 includes two parts, the upper part is a bucket-shaped falling area, and the lower part is a straight cylindrical transfer area. The inner diameter of the transfer area is slightly larger than the outer diameter of the freezing tube 4, so that the freezing tubes 4 can be stacked and stored in the transfer area after falling from the top.

[0027] The wake-up type anti-stuck stirring device 1-2 is placed on the top of the hopper body 1-1 and stirs the inside; a cover body is arranged on the top of the hopper body 1-1, and the wake-up type anti-stuck stirring device 1-2 can be placed on the back of the cover body, including a right-angle motor, a disc and a stirring rod 1-2-1, and the stirring rod 1-2-1 is placed at the bottom of the disc and extends toward the inside of the hopper body 1-1. The right-angle motor drives the disc to rotate, thereby driving the stirring rod 1-2-1 to stir in the hopper body 1-1, and the offset distance of the stirring rod is slightly smaller than the radius of the hopper interface to avoid the freezing tube from getting stuck during the falling process.

[0028] The position detection device 1-3 is a photoelectric tube or an infrared distance sensor, which is placed on the hopper body 1-1 to detect the position of the cryotube 4 inside it, and is mainly used to detect the position of the top of the cryotube in the hopper body. When it is lower than the detection position, the hopper may be empty or the hopper may be stuck. If the hopper is empty, cryotubes can be added or sorting can be completed; if the hopper is stuck, the wake-up anti-stuck stirring device will be activated to ensure that the cryotube falls smoothly from the hopper. This measure not only achieves the purpose of preventing jams, but also minimizes the damage to the sample caused by rotation.

[0029] The sliding and flipping device 2 comprises:

[0030] The differential linear drive module 2-1 is placed on the side of the bottom of the hopper body 1-1. The differential linear drive module 2-1 is connected to a push rod 2-1-1 and a baffle 2-1-2 which are perpendicular to the hopper body 1-1. The push rod 2-1-1 is inserted from the side of the hopper body 1-1 to squeeze and limit the second-to-last cryotube. The baffle 2-1-2 extends from the side to the bottom outlet of the hopper body 1-1 to control the falling of the lowest cryotube through telescopic movement. The linear drive module mainly uses the differential concept when working. When the last cryotube is released, the push rod will act on the cryotube above it to control all the cryotubes above to maintain the current position. The lower baffle is started. Under the action of gravity, the lowest cryotube will fall and the baffle will reset. At this time, the upper push rod is started, and the cryotubes that are still at this time will move downward, thereby achieving the function of screening one by one.

[0031] The visual recognition module 2-2 is placed on the side of the hopper body 1-1, corresponding to the position of the lowest cryotube, to identify its positive and negative states; the visual recognition module is mainly used to identify the state information of the above-mentioned release of the cryotube: because when the cryotube is upright, its upper part is yellow and its lower part is white. Based on this difference, the visual recognition module is installed in the upper half of the cryotube. When yellow is recognized, it is upright; if white is recognized, it is inverted. The recognition information here is communicated with the constant contact flipping device below. It should be noted that the recognition time here should be earlier than the release time in a single cycle, so as to ensure the accuracy of recognition.

[0032] The constant contact flipping device 2-3 is placed below the bottom outlet of the hopper body 1-1, and adjusts the position of the cryopreservation tube according to the judgment of the visual recognition module 2-2, and then drops it to the storage device 3. Specifically, the constant contact flipping device 2-3 includes an arc-shaped slide rail 2-3-1, and a vertical limit leakage hole 2-3-2 is provided at the bottom center of the arc-shaped slide rail 2-3-1. The limit leakage hole 2-3-2, the bottom outlet of the hopper body 1-1 and the arc-shaped slide rail 2-3-1 are located in the same plane, and there is a vertical deviation between the limit leakage hole 2-3-2 and the bottom outlet of the hopper body 1-1, and the arc-shaped slide rail 2-3-1 is provided with a flipping bin 2-3-3 passing through the center of the circle. The two ends of the flipping bin 2-3-3 pass through, and a flipping motor 2-3-4 is provided at the side thereof located at the center of the arc-shaped slide rail 2-3-1. Driven by the flipping motor 2-3-4, the flipping bin 2-3-3 rotates in the arc-shaped slide rail 2-3-1, and one end of the flipping bin 2-3-3 is kept attached to the arc-shaped slide rail 2-3-1; after the cryopreservation tube 4 falls into the flipping bin 2-3-3, the flipping bin 2-3-3 rotates to adjust its posture, and falls from the limiting leak hole 2-3-2.

[0033] like Figure 2As shown, the maximum cross-sectional curvature diameter L1 of the cryogenic tube, the maximum length L2 in the overlapping area between the flip bin and the limit leak hole, and the maximum diameter L3 of the flip bin, the size relationship of each dimension is specified as: L3>L1>L2, which can ensure that when the cryogenic tube falls into the flip bin, it cannot fall into the limit leak hole when the motor does not work.

[0034] The flipping bin shown can be flipped upright or inverted. The specific implementation measures are as follows: when the visual recognition module determines that the released cryotube is upright, the upright flipping function is enabled. Figure 3 As shown in the upright flip: drive the flip bin to rotate clockwise, the cryopreservation tube falls, and then the flip bin rotates counterclockwise to reset; when the above-mentioned visual recognition module determines that the released cryopreservation tube is inverted, the inverted flip function is enabled. Figure 3 As shown in the inverted flip: drive the flip bin, rotate counterclockwise and the cryopreservation tube falls, then the flip tube continues to rotate counterclockwise to reset.

[0035] The storage device 3 includes a slide 3-1 and a storage bin 3-2. The storage bin 3-2 moves on the slide 3-1 and stores and transfers the fallen cryopreservation tubes 4. After completing the storage of a single cryopreservation tube, the slide can first move in the left and right directions under the drive of the motor group. When a row of storage is completed, it will move forward to continue storage, thereby completing the storage. When the storage of 10*10 cryopreservation tubes is completed, the slide is reset and a signal of screening completion is issued.
