Faced with a large number of samples to be tested, it is time-consuming and labor-intensive to manually register the information of the samples one by one, check whether the samples are qualified, and arrange the samples.

The collected results can be used to determine whether the samples are qualified, and the basic information of each sample can be counted in order.

[0027] At least one embodiment of the present disclosure provides a sample processing device, which includes: a sample collection device, a sample transportation device and a counting device. The sample collection device includes a movable transmission mechanism, and is configured to collect samples and transfer the samples from low to high along a first direction to the movable transmission mechanism; the sample transportation device includes an inclined track and a horizontal track, the extension direction of the inclined track intersects with the first direction, the inclined track has a first end and a second end in its extension direction, the height of the second end of the inclined track in the first direction is lower than the height of the first end of the inclined track in the first direction; the inclined track includes a first gap, the extension direction of the first gap is consistent with the extension direction of the inclined track, and the inclined track is configured to receive samples from the movable transmission mechanism, The sample is clamped in the first gap and moves from the first end of the inclined track to the second end of the inclined track along the extension direction of the first gap; the horizontal track is located on the side of the counting device away from the inclined track, is connected to the second end of the inclined track, extends along a horizontal direction intersecting the extension direction of the inclined track, and has a second gap extending along the horizontal direction, and multiple samples are counted one by one by passing through the counting device and enter the second gap in turn; the connection position between the horizontal track and the second end of the inclined track has a corner, and the counting device is located at the corner and is configured to count the samples reaching the corner.

[0028] The sample processing device provided by the embodiment of the present disclosure can be used to collect, for example, a tubular sample containing a substance to be detected, for example, the tubular sample is a nucleic acid detection sample. In the sample processing device, the sample is transmitted along the first direction to a movable transmission mechanism at a higher position by a sample collection device, and a height difference between the movable transmission mechanism and the inclined track is created. The sample can enter the inclined track from the movable transmission mechanism under the action of gravity and be sandwiched in the first gap and slide to the corner. After the multiple samples pass through the counting device one by one to complete the counting of the samples, they can enter the horizontal track in turn, be sandwiched in the second gap and be arranged in turn in the second gap, so that the samples always maintain order during the transportation process from the movable transmission mechanism to the horizontal track, which is convenient for automatic counting of multiple samples one by one and subsequent information collection, and a counting device is set at the corner to cooperate with the inclined track, so that the multiple samples can pass through the counting device one by one under the action of the gravity of the sample, and the structure of the sample processing device is simplified while realizing the transmission of samples and counting of samples.

[0029] It should be noted that the “height in the first direction” in the present disclosure refers to the height relative to the ground in the first direction.

[0030] The transport bearing surface extends along the second direction as a whole, which means that the extension trend of the transport bearing surface is along the first direction, for example, the transport bearing surface may be a straight line extending along the second direction, or the transport bearing surface may be bent or inclined relative to the second direction, but the direction from the starting end to the ending end of the transport bearing surface is along the second direction. The same is true for the receiving bearing surface extending along the second direction as a whole.

[0031] For example, Figure 1 is a schematic block diagram of a moving path of a sample in a sample processing device provided by an embodiment of the present disclosure, Figure 2 is a schematic diagram of the structure of a sample processing device provided by an embodiment of the present disclosure, Figure 3 yes Figure 2 An enlarged schematic diagram of a portion P of the sample processing device is shown. Figure 1-3 At least one embodiment of the present disclosure provides a sample processing device 100, which includes: a sample collection device 10, a sample transportation device 20 and a counting device 30. The sample collection device 10 includes a movable transmission mechanism 3t, and is configured to collect a sample 6 and transfer the sample to the movable transmission mechanism 3t along a first direction D1 from low to high (direction 1 in the figure); the sample transportation device 20 includes an inclined track 21 and a horizontal track 22, the extension direction of the inclined track 21 intersects with the first direction D1, and the inclined track 21 has a first end 21a and a second end 21b in its extension direction, and the height of the second end 21b of the inclined track 21 in the first direction D1 is lower than the height of the first end 21a of the inclined track 21 in the first direction D1; the inclined track 21 includes a first slit 210, the extension direction of the first slit 210 is consistent with the extension direction of the inclined track 21, and the inclined track 21 is configured to receive the sample 6 from the movable transmission mechanism 3t. The sample 6 is clamped in the first gap 210 and moves from the first end 21a of the inclined track 21 to the second end 21b of the inclined track 21 along the extension direction of the first gap 210; the horizontal track 22 is located on the side of the counting device away from the inclined track 21, is connected to the second end 21b of the inclined track 21, extends along a horizontal direction intersecting the extension direction of the inclined track 21, and has a second gap 220 extending along a horizontal direction (for example, a direction basically parallel to the ground, not limited to being absolutely parallel), and multiple samples 6 are counted one by one by the counting device 30 and then enter the second gap 220 in turn; the connection position between the horizontal track 22 and the second end 21b of the inclined track 21 has a corner, and the counting device 30 is located at the corner and is configured to count the samples reaching the corner.

[0032] The sample processing device provided in the embodiment of the present disclosure can be used to collect, for example, a sample 6 containing a substance to be detected, where the sample 6 is a sampling tube, and the sampling tube contains the substance to be detected taken from a test individual (e.g., a human body). For example, the sample 6 is a tubular sample, such as a nucleic acid test sample. Of course, it can also be other types of test samples. In the sample processing device, the sample 6 is transferred along the first direction D1 to a higher movable transmission mechanism 3t through a sample 6 collection device, and a height difference between the movable transmission mechanism 3t and the inclined track 21 is created. The sample 6 can enter the inclined track 21 from the movable transmission mechanism 3t under the action of gravity and be clamped in the first gap 210 and slide to the corner. After a plurality of samples 6 pass through the counting device 30 one by one to complete the counting of the plurality of samples 6, they can enter the horizontal track 22 in turn, be clamped in the second gap 220 and be arranged in turn in the second gap 220, so that the sample 6 always maintains order during the transportation process from the movable transmission mechanism 3t to the horizontal track 21, which is convenient for automatic counting of the plurality of samples 6 one by one and subsequent information collection. In addition, a counting device 30 is arranged at the corner to cooperate with the inclined track 21, so that the plurality of samples 6 can pass through the counting device one by one under the action of gravity of the sample 6, thereby simplifying the structure of the sample processing device 100 while realizing the transmission of samples and the counting of samples.

[0033] refer to Figure 3 For example, the movable transmission mechanism 3t has a movable transmission bearing surface, and the movable bearing surface carries a plurality of samples 6 arranged in a single row. For example, the sample 6 enters the first end 21a of the inclined track 21 through the terminal of the movable bearing surface close to the inclined track 21, and the height of the terminal of the movable bearing surface in the first direction D1 is higher than the height of the first end 21a of the inclined track 21 in the first direction D1. For example, the movable bearing surface extends in the horizontal direction, and the inclined track 21 intersects both the horizontal direction and the vertical direction perpendicular to the ground. In this way, the inclined track 21 can be inclined relative to the ground. For example, the angle between the extension direction of the inclined track 21 and the first direction D1 is greater than 0° and less than 90°. Thereby, the plurality of samples 6 can smoothly enter the inclined track 21 from the movable bearing surface under the action of gravity and slide down to the corner in the first gap 210 under the action of gravity, and then pass through the counting device 30 one by one to complete the counting of the plurality of samples 6.

[0034] refer to Figure 3For example, the inclined track 21 has a first track bearing surface 211 and a second track bearing surface 212, and the first gap 210 is sandwiched between the first track bearing surface 211 and the second track bearing surface 212. For example, the inclined track 21 has a first bearing plate and a second bearing plate, the first bearing plate has a first track bearing surface 211 and the second bearing plate has a second track bearing surface 212, and the first gap 210 is sandwiched between the first bearing plate and the second bearing plate.

[0035] For example, the width of the first slit 210 is adjustable, and the width of the first slit 210 is its dimension in a direction perpendicular to the extension direction of the first slit 210. For example, the first carrier plate and the second carrier plate are detachable, and the width of the first slit 210 between the first carrier plate and the second carrier plate can be changed by replacing the first carrier plate and the second carrier plate with different widths (widths in a direction perpendicular to the extension direction of the first slit 210). Alternatively, the first carrier plate and the second carrier plate can be moved to adjust the distance between them, thereby changing the width of the first slit 210. Of course, the way to adjust the width of the first slit 210 is not limited to the above-mentioned ways.

[0036] refer to Figure 3 For example, a sample includes a main body 6a and an end 6b connected to the main body 6a, the main body 6a and the end 6b are arranged in the axial direction, the orthographic projection of the main body 6a on a plane perpendicular to the axial direction is located within the orthographic projection of the end 6b on a plane perpendicular to the axial direction; the main body 6a has a radial dimension perpendicular to the axial direction, and the end 6b has a radial dimension perpendicular to the axial direction; the width of the first gap 210 of the inclined track 21 is smaller than the radial dimension of the end 6b of the sample and larger than the radial dimension of the main body 6a of the sample, and the sample The main body 6a of the sample is clamped in the first gap 210, and the end 6b of the sample is carried on the first track bearing surface 211 and the second track bearing surface 212, so that after multiple samples 6 are dropped from the movable transmission mechanism 3t to the inclined track 21, the main body 6a of the sample will be automatically clamped in the first gap 210, and the end 6b of the sample will be carried on the first track bearing surface 211 and the second track bearing surface 212, and they are arranged in a single row on the inclined track 21 to facilitate the accuracy and reliability of subsequent counting.

[0037] For example, the sample 6 collected by the sample collection device 10 includes a tube body, and the tube body is an example of a sampling tube for collecting nucleic acid detection, in which a substance for nucleic acid detection is placed; the main part 6a of the sample is the tube body of the nucleic acid detection sampling tube containing the substance to be detected, and the end 6b of the sample is a tube cover for sealing the nucleic acid detection sampling tube, and the axial length of the tube body is greater than the axial length of the tube cover, so that the design of the first gap of the inclined track and the second gap of the horizontal track can match the tube body well, and the longer main part can more stably allow the main part to be clamped in the first gap or the second gap.

[0038] Figure 4 yes Figure 3 A partial enlarged schematic diagram including the corner and the counting device. Figure 4 For example, the counting device 30 is a dial wheel 31, which has a rotating shaft and a turntable 310, and the turntable 310 rotates around the rotating shaft located at the center of the turntable 310. In the circumferential direction around the rotating shaft, that is, on the edge of the turntable 310, a plurality of saw teeth 311 are sequentially arranged, and a groove 312 is provided between two adjacent saw teeth 311, and the surface of the groove 312 is an arc surface. A plurality of samples are arranged in a single row and sequentially transmitted to the dial wheel 31, and the previous sample is engaged with the previous groove 312 of the dial wheel 31, and the dial wheel 31 rotates along the rotating shaft so that the previous sample moves into the second gap 220 of the horizontal track 22 and the next sample is engaged with the next groove 312 adjacent to the previous groove 312. Each time the turntable 310 rotates, one saw tooth 311 moves, corresponding to one sample 6 passing through. In this way, the number of samples 6 passing through the dial wheel 31 can be obtained according to the number of rotations of the dial wheel 31 or the number of saw teeth moved. This method can be effectively coordinated with a plurality of samples 6 arranged in a single row, the structure is easy to implement, the structural complexity of the counting device is reduced, the manufacturing difficulty is reduced, and the counting result is accurate.

[0039] For example, the shape of the main part 6a of the sample 6 is cylindrical, and accordingly, the arc surface is, for example, an arc surface, and the arc surface is complementary to the shape of the cylindrical main part 6a of the sample 6, so as to better enable the arc surface to engage with the outer surface of the main part 6a, which is beneficial to the accuracy and reliability of counting.

[0040] Of course, the counting device may also be implemented in other ways, for example, by setting a sensor to sense the number of samples passing through the sensor, or by taking photos and recording, etc.

[0041] Figure 5 yes Figure 2 The schematic diagram of the sample collection device shown in FIG. Figure 1 and Figure 5The sample collection device 10 includes: a collection and transportation mechanism 1, a sample receiving mechanism 2 and a collection driving mechanism 5. The collection and transportation mechanism 2 is configured to reciprocate along a first direction D1, and includes a transportation bearing surface (taking the first transportation bearing surface 4a as an example) intersecting the first direction D1 and extending along a second direction D2 as a whole, and the second direction D2 is perpendicular to the first direction D1; the sample receiving mechanism 1 has a receiving bearing surface (taking the first receiving bearing surface 3a as an example) intersecting the first direction D1, and the receiving bearing surface extends along the second direction D2 as a whole and is staggered with the transportation bearing surface in a third direction D3, and the third direction D3 is perpendicular to both the first direction D1 and the second direction D2, that is, the orthographic projections of the receiving bearing surface and the transportation bearing surface on the surface perpendicular to the first direction D1 do not overlap. The collection drive mechanism 5 is configured to drive the collection and transportation mechanism 1 to reciprocate along the first direction D1 to drive the transportation carrying surface to reciprocate along the first direction D1. The transportation carrying surface is configured to move downward (for example, toward the ground) along the first direction D1 to a sampling position away from the receiving carrying surface to carry the sample 6, and is configured to move upward (for example, away from the ground) along the first direction D1 to a first junction position close to the receiving carrying surface so that the sample 6 carried on the transportation carrying surface is transferred to the receiving carrying surface. The height of the first junction position in the first direction D1 is not lower than the height of the receiving carrying surface in the first direction D1 and is adjacent to the receiving carrying surface in the third direction D3.

[0042] The sample is collected onto the transport carrying surface, and the transport carrying surface moves along the first direction so that when the transport carrying surface reaches the first intersection position close to the receiving carrying surface, the sample moves toward the receiving carrying surface at a speed along the third direction D3 to be transferred to the receiving carrying surface, thereby realizing the collection and transfer of the sample along the first direction D1. At the same time, since the receiving carrying surface is a non-smooth surface with depressions and protrusions, the sample on the receiving carrying surface will not be able to maintain a vertical state due to unbalanced force, but will be in a horizontal state. The sample in the horizontal state has the largest size in the second direction, and the height in the first direction is smaller than its size in the second direction. For example, when the sample is a test tube sample, the test tube will not be in a vertical state on the receiving carrying surface, but the extension direction of the columnar test tube is consistent with the second direction, that is, the test tube is in a horizontal state, and multiple test tubes are arranged along the second direction to facilitate the orderliness of subsequent transportation and facilitate the subsequent automatic counting and one-by-one information collection of multiple samples.

[0043] Figure 6 yes Figure 5 The sample collection device shown is a schematic diagram of the process of making the sample in a horizontal state on the receiving bearing surface. Here, the horizontal state and the vertical state of the sample are described. Figure 6Sample 6 has three dimensions of length d1, width d2 and height (not marked) in three mutually perpendicular directions. For example, the length d1 of sample 6 is greater than the width d2 of sample 6 and greater than the height of sample 6; when sample 6 is located on the first receiving support surface 3a, sample 6 has a horizontal state (such as sample No. 1 61) and a vertical state (such as sample No. 2); in the horizontal state, such as sample No. 1 61, the length d1 of sample No. 1 61 is along the second direction D2; in the vertical state, such as sample No. 2, the length d1 of sample No. 2 62 is along the first direction D1.

[0044] refer to Figure 5The sample receiving mechanism 2 includes a plurality of receiving bearing surfaces, which are respectively arranged in sequence from low to high in the first direction D1 (direction 1 in the figure) and staggered in the third direction D3, a first receiving bearing surface 3a, a second receiving bearing surface 3b, ..., an Nth receiving bearing surface, the heights of the plurality of receiving bearing surfaces in the first direction D1 are different from each other and the positions are fixed, and N is a positive integer greater than 1; the collection and transportation mechanism 1 includes a plurality of transportation ... second receiving bearing surface 3b, ..., an Nth receiving bearing surface, the heights of the plurality of receiving bearing surfaces in the first direction D1 are different from each other and the positions are fixed, and N is a positive integer greater than 1. a transport carrying surface 4a, a second transport carrying surface 4b, ..., an Nth transport carrying surface; the first receiving carrying surface 3a is located between the first transport carrying surface 4a and the second transport carrying surface 4b in the third direction D3; the first transport carrying surface 4a and the second transport carrying surface 4b are configured to move simultaneously along the first direction D1 from low to high (direction 1 in the figure) to simultaneously reach the first intersection position corresponding to the first receiving carrying surface 3a and the second receiving carrying surface 3b, respectively, so that the sample carried on the first transport carrying surface 4a is transferred to the first receiving carrying surface 3a, and the sample carried on the second transport carrying surface 4b is transferred to the first receiving carrying surface 3a. The sample is transferred to the second receiving carrying surface 3b; the first transport carrying surface 4a and the second transport carrying surface 4b are configured to move simultaneously along the first direction D1 from high to low (direction 2 in the figure) to simultaneously reach the sample initial supply position (located in the sample container 8 containing a large amount of sample 6) and the second intersection position close to the first receiving carrying surface 3a, and the height of the second intersection position in the first direction D1 is lower than the height of the first receiving carrying surface 3a in the first direction D1 and is adjacent to the first receiving carrying surface 3a in the third direction D3, so that the sample at the sample initial supply position is carried to the first receiving carrying surface 3a. The samples carried on the transport carrying surface 4a and the first receiving carrying surface 3a are carried on the second transport carrying surface 4b, and when the second transport carrying surface 4b moves from low to high along the first direction D1 to the first intersection position corresponding to the second receiving carrying surface 3b, the samples carried on the second transport carrying surface 4b are transferred to the second receiving carrying surface 3b; the first intersection position and the second intersection position corresponding to the first receiving carrying surface 3a are respectively located on the first side of the first receiving carrying surface 3a away from the second receiving carrying surface 3b and the second side close to the second receiving carrying surface 3b in the third direction D3. For example, the first transport carrying surface 4a and the second transport carrying surface 4b move from low to high along the first direction D1 at the same time or move from high to low along the first direction D1 at the same time. In this way, the first transport carrying surface 4a and the second transport carrying surface 4b reciprocate in the first direction D1, while the first receiving carrying surface 3a and the second receiving carrying surface 3b remain fixed in position, so as to transfer the sample from low to high in the first direction D1 to the second receiving carrying surface 3b with a higher position, and to transfer the sample from low to high along the first direction while keeping the sample in a horizontal state on the second receiving carrying surface 3b.

[0045] For example, N is greater than 2, and the adjacent receiving bearing surfaces and the adjacent transport bearing surfaces in the first direction D1 work like the above-mentioned cooperation between the first receiving bearing surface 3a and the second receiving bearing surface 3b and the first transport bearing surface 4a and the second transport bearing surface 4b, so as to realize the step-by-step transfer of the sample 6 upward along the first direction D1, thereby ensuring the reliability of the upward transfer of the sample along the first direction D1, being adaptable to a relatively large transfer distance, and ensuring that there is a sufficient height difference between the movable transmission mechanism 3t and the inclined track 21 in the first direction D1.

[0046] A plurality of samples 6 are arranged in a single row along the second direction D2 on each receiving support surface, and the Nth receiving support surface is used as a movable support surface for carrying the samples 6 of a movable transport mechanism 3t, and the movable transport mechanism is configured to transport the plurality of samples 6 arranged in a single row and located on the support surface of the movable transport mechanism to the inclined track via the first end of the inclined track.

[0047] For example, refer to Figure 5 The collecting and transporting mechanism 1 includes a transport plate extending along a first direction D1, the transport plate includes a plurality of sub-transport plates arranged in the first direction D1 and staggered in a third direction D3, the plurality of sub-transport plates include a first sub-transport plate 11 and a second sub-transport plate 12, the first sub-transport plate 11 has a first transport bearing surface 4a, and the second sub-transport plate 12 has a second transport bearing surface 4b; the sample receiving mechanism 2 includes a receiving plate extending along the first direction D1, the receiving plate includes a plurality of sub-transport plates arranged in the first direction D1 and staggered in a third direction D3 Sub-receiving plates, multiple sub-receiving plates, a first sub-receiving plate 21 and a second sub-receiving plate 22, the first sub-receiving plate 21 has a first receiving bearing surface 3a, and the second sub-receiving plate 22 has a second receiving bearing surface 3b; the collecting driving mechanism 5 is configured to drive the first sub-transport plate 11 and the second sub-transport plate 12 to reciprocate along the first direction D1 so that the first transport bearing surface 4a and the second transport bearing surface 4b reciprocate along the first direction D1; the second sub-transport plate 12 is located between the first sub-receiving plate 21 and the second sub-receiving plate 22 in the third direction D3.

[0048] For example, the sample collection device 10 further includes: a sensor and an ejection mechanism. The sensor is disposed at a sensing position on at least one of the two sides of each receiving bearing surface in the second direction. The ejection mechanism is disposed on at least one of the two sides of each receiving bearing surface in the second direction. For example, referring to Figure 6, the sensor includes a first sensor 1a, and the ejection mechanism includes a first ejection mechanism 2a. The first sensor 1a is disposed at a first sensing position on the first blocking mechanism 7a, and is configured to sense a sample located at a first end of a receiving bearing surface corresponding to the first blocking mechanism 7a and at a position substantially the same height as the first sensing position, such as sample No. 2 62 in a vertical state, the height of the first sensing position being the height of the first sensing position relative to the receiving bearing surface corresponding to the first blocking mechanism 7a in the first direction D1, and the value of the height of the first sensing position being greater than the value of the width of the sample 6 and greater than the value of the height of the sample 6 and less than the value of the length d1 of the sample; for example, the tube body of the sample 6 is cylindrical, and the height of the sample 6 is equal to the width d2 of the sample 6; for example, the height and width of the sample 6 here refer to the maximum height of the sample 6 in the height direction and the maximum width in the width direction, because the height and width of the sample 6 at various positions may not be equal. For example, the first spraying mechanism 2a is arranged on the first blocking mechanism 7a and is configured as follows: when the first sensor 1a senses the presence of a sample at the first end of the corresponding receiving support surface and at a position substantially the same height as the first sensing position, a force-applying substance is sprayed toward the sample to apply force to the sample at a position substantially the same height as the first sensing position to knock the sample down onto the corresponding receiving support surface so that the sample is in a horizontal state. After multiple samples 6 are transferred to the first receiving support surface 3a, a corner is formed between the inner side surface 71 of the first blocking mechanism 7a facing the first receiving support surface 3a and the plate surface of the second sub-transport plate 12 extending along the first direction D1. The sample (taking sample No. 2 62 as an example) is easily in a vertical state at the corner under the support of the inner side surface 71 of the first blocking mechanism 7a and the plate surface of the second sub-transport plate 12. At this time, since the length d1 is greater than the width of the sample 6 and greater than the height of the sample 6, for example, the height of the top surface of sample No. 2 62 in the first direction D1 exceeds the height of the first sensor 1a in the first direction D1, therefore, the first sensor 1a can sense that there is a sample at the first sensing position, so that the first spraying mechanism 2a sprays a force-applying substance toward sample No. 2 62 to apply force to sample No. 2 62 and knock the sample down on the first receiving support surface 3a to transform the sample into the horizontal state of sample No. 1 61. In this way, combined with designing the width of each receiving support surface in the third direction D3 to be narrower, for example, to accommodate a single row of horizontal samples 61, it can be ensured that the samples on the movable support surface of the movable transmission mechanism 3t are all in a horizontal state and arranged in a single row along the moving direction of the movable support surface of the movable transmission mechanism 3t.

[0049] For example, the sample collection device 10 further includes a second sensor (not shown) and a second ejection mechanism (not shown). The second sensor is disposed at a second sensing position on the second blocking mechanism 7b, and is configured to sense a sample located at the second end of the receiving bearing surface corresponding to the second blocking mechanism 7b and at a position substantially the same height as the second sensing position, wherein the height of the second sensing position is the height of the second sensing position relative to the receiving bearing surface corresponding to the second blocking mechanism 7b in the first direction D1, and the value of the height of the second sensing position is greater than the value of the width of the sample and greater than the value of the height of the sample and less than the value of the length of the sample; the second ejection mechanism is disposed on the second blocking mechanism 7b, and is configured to: when the second sensor senses that there is a sample at the second end of the corresponding receiving bearing surface and at a position substantially the same height as the second sensing position, eject a force-applying substance toward the sample to apply a force to the sample at a position substantially the same height as the second sensing position, and knock the sample down on the corresponding receiving bearing surface so that the sample is in a horizontal state. For example, the height of the second sensing position is equal to the height of the first sensing position. The working processes of the second sensor and the second ejection mechanism are respectively the same as those of the first sensor and the first ejection mechanism. For example, the positions of the second sensor and the second spraying mechanism are axisymmetric with respect to the positions of the first sensor and the first spraying mechanism, respectively, in the second direction D2.

[0050] For example, the force-applying material sprayed by the first spray mechanism and the second spray mechanism is compressed air, so that a good knocking-down effect can be achieved without causing contamination to the sample.

[0051] refer to Figure 4 For example, the sample processing device 100 further includes an information collection area R1, a portion of the horizontal track 22 and a portion of the second gap 220 are located in the information collection area R1, and the sample 6 can be transported to the information collection area R1 along the horizontal track 22; the information collection device 40 is located in the information collection area R1, and is configured to collect information of the sample in the information collection area R1. In this way, through the mutual cooperation of the sample collection device, the sample transportation device, the counting device and the information collection device, it is realized that before automatically performing the steps of registering information of the samples one by one and checking whether the samples are qualified, the samples are automatically collected, counted and transmitted to the information collection area R1 one by one, and then the information of the samples is collected in the information collection area R1, and the collected results can be used to determine whether the samples are qualified, and the basic information of each sample is counted in order.

[0052] Figure 7 is a schematic diagram of the relationship between the control system and various structures of a sample processing device provided by an embodiment of the present disclosure. Figure 7The sample collection device 10 also includes a control system 4, which is signal-connected to the information collection device 40 (wireless signal connection or wired signal connection such as electrical connection), and is configured to control the information collection device 40 to collect information from multiple samples located in the information collection area R1.

[0053] For example, refer to Figure 7 , the control system 4 is signal-connected with the first sensor 1a and the second sensor, and the first spraying mechanism 2a and the second spraying mechanism (wireless signal connection or wired signal connection such as electrical connection). For example, the first sensor 1a and the second sensor perform real-time sensing, and transmit the sensing results to the control system 4 in real time. The control system 4 includes a judgment module, which executes a judgment step to determine whether there is a sample at the first sensing position. If the judgment result is "yes", the control system 4 controls the first spraying mechanism 2a to spray the force-applying substance. If the judgment result is "no", the control system 4 controls the first spraying mechanism 2a not to spray the force-applying substance. Similarly, the judgment module also executes a judgment step to determine whether there is a sample at the second sensing position. If the judgment result is "yes", the control system 4 controls the second spraying mechanism to spray the force-applying substance. If the judgment result is "no", the control system 4 controls the second spraying mechanism not to spray the force-applying substance.

[0054] For example, refer to Figure 7 The control system 4 can also be connected to the acquisition drive mechanism 5 by signal (wireless signal connection or wired signal connection such as electrical connection), and is configured to control the acquisition drive mechanism 5 to perform work and working parameters, such as motor speed, motor working time, etc.
