[0045] Please refer to Figure 1 , Figure 1 is a structural schematic diagram of an embodiment of a sample tube sorting device 1 provided by the present application. The sample tube sorting device 1 provided by the embodiment of the present application comprises a sample tube storage assembly 11, a sample tube fishing assembly 12, a sample tube conveying assembly 13 and a sample tube identification assembly 14.

[0046] Among them, the sample tube storage assembly 11 is used to store the sample tubes to be sorted, the first end of the sample tube fishing assembly 12 is arranged in the sample tube storage assembly 11, and the first end of the sample tube conveying assembly 13 is arranged in the sample tube fishing assembly 12. The second end of the sample tube fishing assembly 12 is arranged in the sample tube conveying assembly 13, the sample tube fishing assembly 12 is used to move the sample tubes in the sample tube storage assembly to the sample tube conveying assembly 13, and the sample tube conveying assembly 13 is used to receive the sample tubes on the sample tube fishing assembly 12; the sample tube identification assembly 14 is arranged in the second end of the sample tube conveying assembly 13, and is used to identify the sample tubes conveyed by the sample tube conveying assembly 13 and classify the sample tubes.

[0047] In the sample tube sorting device 1 provided by the embodiment of the present application, the cooperation of the sample tube storage assembly 11, the sample tube fishing assembly 12, the sample tube conveying assembly 13 and the sample tube identification assembly 14 realizes the automatic sorting of the sample tubes, reduces the manual participation in the sample tube sorting operation, and thus can reduce the errors caused by the manual sorting of the sample tubes, improve the efficiency of the sample tube sorting device 1 in sorting the sample tubes, and improve the user's experience in using the sample tube sorting device 1.

[0048] Optionally, please continue to refer to Figure 2 and Figure 3 , Figure 2 is a structural schematic diagram of an embodiment of a sample tube storage assembly 11 and a sample tube fishing assembly 12 provided by the present application, Figure 3 is Figure 2A structural schematic diagram of a local region B in the sample tube storage assembly 11 is shown in FIG. 3. The sample tube fishing assembly 12 comprises sawtooth fishing claws 121, and the sample tube storage assembly 11 comprises a comb plate 111 arranged close to the sample tube fishing assembly 12.

[0049] The comb plate 111 is provided with an avoiding slot corresponding to the sawtooth fishing claws 121 to allow the sawtooth fishing claws 121 to pass through the avoiding slot and fish the sample tubes in the sample tube storage assembly 11. Specifically, as shown in FIG. 4, when the sawtooth fishing claws 121 pass through the avoiding slot formed by the comb plate 111, the combs on the comb plate 111 and the sawteeth on the sawtooth fishing claws 121 are interlaced with each other, and then the sawtooth fishing claws 121 can pass through the through hole formed by the comb plate 111 to fish the sample tubes in the sample tube storage assembly 11. Figure 3

[0050] Thanks to the cooperation of the comb plate 111 and the sawtooth fishing claws 121, the sawtooth fishing claws 121 can pass through the avoiding slot formed by the comb plate 111 to enter the sample tube storage assembly 11, and after the sawtooth fishing claws 121 fish the sample tubes away, the remaining sample tubes in the sample tube storage assembly 11 will not fall from the avoiding slot due to the blocking of the combs on the comb plate 111 at the avoiding slot, thus improving the safety of the sample tube storage assembly 11 in storing the sample tubes to be sorted and improving the safety of the sample tube sorting device 1.

[0051] In an embodiment, the sample tube sorting device 1 can further comprise a horizontal pushing plate (not shown in the figure) arranged on the side of the sample tube fishing assembly 12 away from the sample tube conveying assembly 13, which can push the sample tubes on the sample tube fishing assembly 12 to the sample tube conveying assembly 13 when the sample tubes are fished and moved to the region corresponding to the sample tube conveying assembly 13.

[0052] Optionally, referring to FIG. 5, Figure 2 the sample tube fishing assembly 12 further comprises a first conveying belt 122, at least two rotating wheels (not shown in the figure) and a plurality of sawtooth fishing claws 121.

[0053] The first conveying belt 122 is arranged around the at least two rotating wheels, which are used to drive the first conveying belt 122, and the plurality of sawtooth fishing claws 121 are arranged on the first conveying belt 122 at intervals, and the first end of the first conveying belt 122 is arranged in the sample tube storage assembly 11.

[0054] Among them, one of the at least two rotating wheels can be arranged below the sample tube storage assembly 11 and spaced apart from the avoiding slot; one of the at least two rotating wheel assemblies can be arranged above the sample tube storage assembly 11, and then the first conveying belt 122 is arranged around the at least two rotating wheels and close to the avoiding slot, and then the sawtooth fishing claws 121 arranged on the first conveying belt 122 can cooperate with the avoiding slot. ​

[0055] The sample tube fetching assembly 12 can further comprise a driving motor (not shown in the figure), which is connected with the driving wheel, and drives the driving wheel to rotate. Since the first conveying belt 122 is arranged around the rotating wheels, the rotation of the driving wheel drives the rotation of the driving wheel and the driven wheels, so as to drive the plurality of sawtooth claws 121 to enter the sample tube storage assembly 11 through the avoiding slots in sequence to fetch the sample tubes.

[0056] Optionally, please continue to refer to Figure 4 , Figure 4 is Figure 1 a structural diagram of a local area A in the sample tube sorting device 1. The sample tube fetching detection assembly 15 is further included in the sample tube sorting device 1. Part of the sample tube fetching detection assembly 15 is arranged on the first rotating wheel. The first rotating wheel is one of the at least two rotating wheels. As described above, the at least two rotating wheels include a driving wheel and a driven wheel. Therefore, part of the sample tube fetching detection assembly 15 can be arranged on the driving wheel or the driven wheel, which is not limited in the present application.

[0057] In the sample tube fetching detection assembly 15, the rotating code disc 151 is arranged at one end of the first rotating wheel. The rotating axis of the rotating code disc 151 coincides with the rotating axis of the first rotating wheel. The cross section of the rotating code disc 151 perpendicular to the rotating axis is circular. The plurality of baffle plates 152 are arranged at the edge of the rotating code disc 151. The distance between any two adjacent baffle plates 152 is equal. The detection device 153 is arranged at a distance from the rotating code disc 151.

[0058] Specifically, since the rotating code disc 151 is arranged on the first rotating wheel, the rotating code disc 151 can rotate with the first rotating wheel. The rotating axis of the rotating code disc 151 overlaps with the rotating axis of the first rotating wheel, which ensures the concentric and synchronous rotation of the rotating code disc 151 and the first rotating wheel. That is, the rotation of the rotating code disc 151 can represent the rotation of the first rotating wheel.

[0059] In an embodiment, the detection device 153 can be a detection photoelectric coupler, and the baffle plate 152 can be a photoelectric coupler baffle plate. The baffle plate 152 is used to block the light generated in the detection photoelectric coupler, so as to change the level in the detection photoelectric coupler.

[0060] Wherein, the plurality of baffle plates 152 are arranged on the edge of the rotating disc 151, and the detection device 153 is arranged at intervals with the rotating disc 151. When the rotating disc 151 rotates with the first rotating wheel, the baffle plate 152 will enter the detection device 153, and the baffle plate 152 will shield the light generated by the detection device 153, so that the level in the detection device 153 is switched from high level to low level. After the rotating disc 151 rotates and the baffle plate 152 is taken out of the detection device 153, the light generated by the detection device 153 is not shielded, and the level in the detection device 153 is changed from low level to high level.

[0061] Further, the rotating disc 151 is circular along the cross section perpendicular to the rotation axis, and the distance between any two adjacent baffle plates 152 is equal. When the first rotating wheel rotates at a constant speed, the rotating disc 151 will drive the plurality of baffle plates 152 to enter the detection device 153 in turn and regularly. During the process of the first rotating wheel rotating at a constant speed, the level in the detection device 153 appears regular high-low level conversion. When the first rotating wheel rotates in a jam, the baffle plate 152 is located in the detection device 153 for too long, or the baffle plate 152 is slow to enter the detection device 153, and the level in the detection device 153 appears high-low level conversion jam. At this time, the sample tube fishing assembly 12 can be responded to run in a jam, and the fault can be reported, so that the sample tube sorting device 1 can be maintained to improve the stability of the sample tube sorting device 1.

[0062] In summary, the sample tube fishing detection assembly 15 is arranged to detect the operation of the sample tube fishing assembly 12. When the sample tube fishing assembly 12 runs in a jam, the fault can be reported in time to improve the stability of the sample tube sorting device 1.

[0063] In an embodiment, please refer to Figure 5 , Figure 5 is a structural schematic diagram of an embodiment of the sample tube reversing assembly 16 and the sample tube storage disc 17 of the present application. The sample tube sorting device 1 provided by the embodiment of the present application further comprises a sample tube reversing assembly 16 and a sample tube storage disc 17.

[0064] Wherein, the sample tube reversing assembly 16 is arranged at intervals with the sample tube identification assembly 14 and the sample tube storage disc 17 respectively, for receiving the sample tubes classified by the sample tube identification assembly 14, and converting the sample tubes in horizontal posture to vertical posture, and the sample tube storage disc 17 is used for receiving and storing the sample tubes in vertical posture.

[0065] Specifically, as shown in Figure 6 and Figure 7 , Figure 6 is Figure 5 a side view structural schematic diagram of the sample tube reversing assembly 16 and the sample tube storage disc 17 in Figure 7 isFigure 5 FIG. 2 is a top view of the sample tube reversing assembly 16 and the sample tube storage tray 17. The sample tube reversing assembly 16 of the present embodiment includes a guide funnel 161 and a reversing rail 162.

[0066] The guide funnel 161 is spaced apart from the sample tube identification assembly 14, the first end of the reversing rail 162 is spaced apart from the guide funnel 161, and the second end of the reversing rail 162 is spaced apart from the sample tube storage tray 17. Thus, after the sample tube is identified and classified in the sample tube identification assembly 14, the sample tube can enter the guide funnel 161 from the sample tube identification assembly 14. Since the sidewall of the guide funnel 161 is inclined to the reversing rail 162, the guide funnel 161 can guide the sample tube to the reversing rail 162. The sample tube is changed from a horizontal posture to a vertical posture on the reversing rail 162 and enters the sample tube storage tray 17 through the second end of the reversing rail 162 for storage.

[0067] In an embodiment, the guide funnel 161 can be arranged below the sample tube identification assembly 14, and the reversing rail 162 is arranged below the guide funnel 161. Thus, after the sample tube is identified and classified in the sample tube identification assembly 14, the sample tube can fall on the guide funnel 161 under the action of gravity and move to the reversing rail 162 due to the guiding action of the guide funnel 161 and the action of gravity.

[0068] In the present embodiment, the sample tube sorting device 1 can further include a mechanical arm assembly (not shown in the figure). The mechanical arm assembly can move into the sample tube storage tray 17 to clamp the identified and classified sample tube. Since the sample tube in the sample tube storage tray 17 is in a vertical posture, the difficulty of clamping the sample tube by the mechanical arm assembly is reduced, and the efficiency of the sample tube sorting device 1 is further improved.

[0069] In an embodiment, as shown in FIG. 1, the sample tube reversing assembly 16 can further include a vertical pushing member 163 spaced apart from the reversing rail 162. The vertical pushing member 163 is used to push the sample tube in the reversing rail 162 in a vertical posture to the sample tube storage tray 17. Further, the sample tube reversing assembly 16 can further include a driving synchronous belt 164 connected to the vertical pushing member 163. The driving synchronous belt 164 is used to drive the movement of the vertical pushing member 163. Figure 5 Figure 7 In an embodiment, as shown in FIG. 1, the sample tube reversing assembly 16 can further include a vertical pushing member 163 spaced apart from the reversing rail 162. The vertical pushing member 163 is used to push the sample tube in the reversing rail 162 in a vertical posture to the sample tube storage tray 17. Further, the sample tube reversing assembly 16 can further include a driving synchronous belt 164 connected to the vertical pushing member 163. The driving synchronous belt 164 is used to drive the movement of the vertical pushing member 163.

[0070] ​In another embodiment, the sample tube storage disc 17 can include a storage disc 171 and a limiting ring 172. The storage disc 171 is provided with a plurality of sample tube storage positions around the storage disc 171, and the size of each sample tube storage position corresponds to the tube diameter of the sample tube. In this way, the sample tube can be moved from the sample tube reversing assembly 16 to the sample tube storage disc 17 for storage. The limiting ring 172 is arranged on the outer periphery of the storage disc 171, and the inner diameter of the limiting ring 172 is equal to or slightly larger than the diameter of the storage disc 171. In this way, during the process of rotating the storage disc 171 to move the empty sample tube storage position to the second end of the reversing guide rail 162 to accommodate the sample tube, the limiting ring 172 limits the sample tube stored on the storage disc 171, avoiding the situation that the sample tube is thrown out of the storage disc 171 due to the rotation of the storage disc 171, and improving the safety of the sample tube storage disc 17 in storing the sample tube.

[0071] Optionally, the reversing guide rail 162 includes a first reversing strip 1621 and a second reversing strip 1622. The first reversing strip 1621 and the second reversing strip 1622 are arranged in parallel and at intervals, and the distance between the first reversing strip 1621 and the second reversing strip 1622 is greater than the tube diameter of the sample tube and less than the cap diameter of the sample tube. In this way, when the sample tube enters the reversing guide rail 162 from the horizontal posture, due to the action of gravity, the tube of the sample tube will enter the gap between the first reversing strip 1621 and the second reversing strip 1622, and the cap of the sample tube will be clamped on the gap. In this way, the sample tube changes from the horizontal posture to the vertical posture.

[0072] In an embodiment, the first reversing strip 1621 and the second reversing strip 1622 can be arranged obliquely, and obliquely towards the sample tube storage disc 17. In this way, after the sample tube changes to the vertical posture, it will gradually move to the second end of the reversing guide rail 162 under the action of gravity, and then be stored in the sample tube storage disc 17.

[0073] In another embodiment, the reversing guide rail 162 further includes a limiting spring 1623. The limiting spring 1623 is arranged at the second end of the reversing guide rail 162. Specifically, the reversing guide rail 162 can include two limiting springs 1623, and the two limiting springs 1623 are arranged at one end of the first reversing strip 1621 close to the sample tube storage disc 17 and one end of the second reversing strip 1622 close to the sample tube storage disc 17, respectively. In this way, the sample tube stored in the sample tube storage disc 17 is prevented from returning to the reversing guide rail 162, and the sample tube in the reversing guide rail 162 is prevented from being collided. In this way, the safety of the sample tube storage disc 17 is further improved.

[0074] Optionally, please refer to Figure 8 , Figure 8is a structural schematic diagram of an embodiment of a sample tube pushing assembly 18 of the present application. The sample tube sorting device 1 further comprises a sample tube pushing assembly 18, which is arranged at a position spaced apart from the second end of the sample tube conveying assembly 13, and pushes the sample tube into the sample tube identifying assembly 14 when the sample tube conveying assembly 13 conveys the sample tube to the second end of the sample tube conveying assembly 13.

[0075] The sample tube pushing assembly 18 comprises a pushing rail 181, a connecting piece 182 and a pushing plate 183. The pushing rail 181 is arranged perpendicularly to the conveying direction of the sample tube conveying assembly 13. The connecting piece 182 is arranged on the pushing rail 181. One end of the pushing plate 183 is connected to the connecting piece 182, and the pushing plate 183 is arranged parallel to the conveying direction of the sample tube conveying assembly 13.

[0076] Before the sample tube conveying assembly 13 conveys the sample tube to the second end of the sample tube conveying assembly 13, the connecting piece 182 is located at the first end of the pushing rail 181, and the pushing plate 183 is in an initial state. When the sample tube conveying assembly 13 conveys the sample tube to the second end of the sample tube conveying assembly 13, the connecting piece 182 is moved from the first end of the pushing rail 181 to the second end of the pushing rail 181, and the pushing plate 183 is driven to push the sample tube at the second end of the sample tube conveying assembly 13 to the sample tube identifying assembly 14.

[0077] In an embodiment, please refer to Figure 8 The end of the pushing plate 183 away from the connecting piece 182 is provided with a chamfer, so as to limit the sample tube during the process of contacting the pushing plate 183 and pushing the sample tube, avoid the sample tube from falling due to displacement during the process of being pushed, and improve the safety of moving the sample tube.

[0078] Optionally, please refer to Figure 9 , Figure 9 is a structural schematic diagram of an embodiment of a sample tube identifying assembly of the present application. The sample tube identifying assembly 14 comprises a first rubber roller 141, a second rubber roller 142 and an identifying module 143.

[0079] The first rubber roller 141 and the second rubber roller 142 are arranged spaced apart, and the identifying module 143 is arranged spaced apart from the first rubber roller 141 and the second rubber roller 142. The first rubber roller 141 and the second rubber roller 142 are configured to have a first state in which the interval distance between the first rubber roller 141 and the second rubber roller 142 is less than the tube diameter of the sample tube, and a second state in which the interval distance between the first rubber roller 141 and the second rubber roller 142 is greater than the cap diameter of the sample tube.

[0080] Specifically, the first rubber roller 141 can be a driving rubber roller, and the second rubber roller 142 can be a driven rubber roller. The sample tube identification assembly 14 can further include a rotating motor 144 connected with the first rubber roller 141 to drive the first rubber roller 141 to rotate.

[0081] When the first rubber roller 141 and the second rubber roller 142 are configured to have a first state in which a spacing distance between the first rubber roller 141 and the second rubber roller 142 is less than a tube diameter of the sample tube, the sample tube pushing assembly 18 can push the sample tube from the sample tube conveying assembly 13 to a space between the first rubber roller 141 and the second rubber roller 142. Since the spacing distance between the first rubber roller 141 and the second rubber roller 142 is less than the tube diameter of the sample tube, the sample tube is clamped between the first rubber roller 141 and the second rubber roller 142, and the sample tube and the second rubber roller 142 rotate synchronously with the first rubber roller 141 during rotation of the first rubber roller 141. The identification module 143 can be arranged above the first rubber roller 141 and the second rubber roller 142. During rotation of the sample tube driven by the first rubber roller 141, the identification module 143 scans the rotating sample tube to realize rotating code scanning of the sample tube and improve the identification efficiency of the sample tube.

[0082] After the identification module 143 finishes scanning the sample tube, the second rubber roller 142 can move away from the first rubber roller 141. The first rubber roller 141 and the second rubber roller 142 are switched to a second state in which a spacing distance between the first rubber roller 141 and the second rubber roller 142 is greater than a cap diameter of the sample tube. Then, the sample tube can fall into a gap between the first rubber roller 141 and the second rubber roller 142. As described above, the sample tube reversing assembly 16 can be arranged below the sample tube identification assembly 14. After the sample tube falls between the first rubber roller 141 and the second rubber roller 142 due to gravity, the sample tube directly falls into the sample tube reversing assembly 16 for reversing.

[0083] The first rubber roller 141 and the second rubber roller 142 drive the sample tube to rotate, realize rotating code scanning of the sample tube, improve the identification efficiency of the sample tube, and improve the sorting efficiency of the sample tube sorting device 1. The switching between the first state and the second state of the first rubber roller 141 and the second rubber roller 142 can realize rotating code scanning of the sample tube in the sample tube identification assembly 14 and moving the sample tube to the sample tube reversing assembly 16. No additional moving assembly is needed to move the sample tube between the sample tube identification assembly 14 and the sample tube reversing assembly 16, and the smoothness of moving the sample tube between the sample tube identification assembly 14 and the sample tube reversing assembly 16 is improved.

[0084] Optionally, as shown in FIG. 1B, the sample tube sorting device 1 can further include a sample tube conveying assembly 13 arranged below the sample tube pushing assembly 18. The sample tube conveying assembly 13 can convey the sample tube to the sample tube pushing assembly 18. Figure 10 Figure 10 ​is a structural schematic view of an embodiment of the sample tube transportation assembly 13 of the present application. The sample tube transportation assembly 13 provided by the embodiment of the present application comprises a second conveying belt 131, a transportation limiting piece 132, and a transportation-in-position detector 133.

[0085] The first end of the second conveying belt 131 is spaced apart from the sample tube fishing assembly 12, the second end of the second conveying belt 131 is spaced apart from the sample tube identification assembly 14, the transportation limiting piece 132 is spaced apart from the middle part of the second conveying belt 131, and the transportation-in-position detector 133 is spaced apart from the transportation limiting piece 132.

[0086] Specifically, as shown in Figure 10 , the transportation limiting piece 132 can be in the shape of an inverted U along the cross section of the second conveying belt 131 in the direction of transportation of the sample tube, and is arranged in the middle part of the second conveying belt 131 to form a passage allowing one sample tube to pass through. In the passage, the arrangement direction of the sample tube needs to be parallel to the conveying direction of the sample tube by the second conveying belt 131, that is, the transportation limiting piece 132 can guide the sample tube conveyed by the second conveying belt 131 and adjust the posture of the sample tube, so as to avoid the arrangement direction of the sample tube deviating from the transportation direction of the sample tube by the second conveying belt 131 and falling off the second conveying belt 131 during transportation, thereby improving the safety of transportation of the sample tube in the sample tube transportation assembly 13.

[0087] Further, the transportation-in-position detector 133 can be spaced apart from the transportation limiting piece 132, and specifically, the transportation-in-position detector 133 can be arranged above the transportation limiting piece 132, thereby detecting the sample tube entering the passage formed by the transportation limiting piece 132, detecting whether the sample tube enters the passage formed by the transportation limiting piece 132 (if the arrangement direction of the sample tube deviates too much from the transportation direction of the sample tube by the second conveying belt 131, the sample tube cannot enter the passage and will be stuck at the passage entrance), and detecting whether the transportation of the sample tube in the passage is smooth (whether the sample tube is stuck in the passage), so as to avoid the sample tube being stuck at the transportation limiting piece 132, affecting the transportation efficiency of the sample tube by the sample tube transportation assembly 13, and improving the smoothness and safety of transportation of the sample tube in the sample tube transportation assembly 13.

[0088] Optionally, referring to Figure 2 , the sample tube storage assembly 11 of the embodiment of the present application further comprises a sample tube storage bin 112 and a storage detector (not shown in the figure).

[0089] Specifically, the sample tube storage bin 112 includes a plurality of support plates 1121, which are arranged on the comb plate 111 and surround a storage space for placing sample tubes. An included angle between each support plate 1121 and the comb plate 111 is obtuse, that is, the plurality of support plates 1121 and the comb plate 111 form a funnel structure. Under the guidance of the support plates 1121 and the action of gravity, the sample tubes in the sample tube storage bin 112 gather at the lowest point of the storage space (the comb plate 111). Then, the sawtooth claw 121 can contact the sample tubes through the through hole of the comb plate 111 to pick up the sample tubes, avoiding the sample tubes from falling in other positions of the sample tube storage bin 112, and the sawtooth claw 121 cannot contact the sample tubes, causing the accumulation of the sample tubes in the sample tube storage bin 112, which affects the sorting efficiency of the sample tubes.

[0090] Further, the storage detector is arranged on the comb plate 111 and is spaced apart from the avoiding groove. Then, the storage detector can be used to detect the sample tubes in the sample tube storage bin 112. Since the comb plate 111 is the lowest point of the sample tube storage bin 112, that is, when the storage detector detects that there is no sample tube at the comb plate 111, it can be judged that the sample tubes in the sample tube storage bin 112 are exhausted, and the sample tubes need to be supplemented to avoid the situation that the sample tubes in the sample tube storage bin 112 are exhausted while the sample tube sorting device 1 is still running empty, wasting energy, improving the sorting efficiency of the sample tube sorting device 1 for the sample tubes.

[0091] In summary, the sample tube sorting device 1 provided by the embodiment of the present application includes a sample tube storage assembly 11, a sample tube picking-up assembly 12, a sample tube transportation assembly 13, and a sample tube identification assembly 14, which realizes the automatic sorting of sample tubes, reduces the manual participation in the sample tube sorting operation, and then can reduce the error caused by manual sorting of sample tubes, improves the efficiency of the sample tube sorting device 1 for sorting sample tubes, and improves the user experience of the sample tube sorting device 1.

[0092] Meanwhile, the sample tube sorting device 1 further includes a sample tube picking-up detection assembly 15 for detecting whether the operation of the sample tube picking-up assembly 12 is stuck, a sample tube pushing assembly 18 for pushing the movement of the sample tubes between the sample tube transportation assembly 13 and the sample tube identification assembly 14, a sample tube reversing assembly 16 for adjusting the posture of the sample tubes, and a sample tube storage disc 17 for storing the sample tubes, which further improves the efficiency of the sample tube sorting device 1 for sorting sample tubes, and improves the practicality and safety of the sample tube sorting device 1.

[0093] The application also provides a sample tube processing device (not shown in the figure) comprising the sample tube sorting device 1. In an embodiment, the sample tube processing device can further comprise a sample tube moving device for moving the sample tubes sorted by the sample tube sorting device 1 to a sample tube rack, and a conveying device for conveying the sample tube rack loaded with the sample tubes to a sample analyzer arranged at a distance from the sample tube processing device, so as to realize automation and intelligentization of sample detection by the sample analyzer.

[0094] The above description is merely an embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the present application.
