Description

Technical Field

[0001] The present invention relates to the technical field of sample testing, and more particularly to a single-tube circulating orderly sample injection system. Background Art

[0002] In existing technologies, when testing samples, all samples must be categorized by test item, with samples for the same test item belonging to the same category. When processing samples for the same category, the analyzer does not need to reset test conditions, allowing the analyzer to operate continuously. However, when processing samples for different test items, the analyzer needs to reset test conditions, a process that takes considerable time.

[0003] Currently, the sampling track of an analyzer uses a 5-hole rack-style sampling method. This means that five sample tubes are placed in a single 5-hole rack as a group. The sampling track delivers one 5-hole rack to the analyzer at a time. Each 5-hole rack contains five sample tubes, and the sampling module does not classify the samples to be tested, resulting in the five sample tubes not necessarily belonging to the same test item. This sampling method may cause the analyzer to constantly switch between different test items and constantly reset test conditions, seriously affecting the analyzer's processing speed. In other words, it is impossible to sequentially inject samples according to the analyzer's requirements. This sampling method is less flexible and cannot be well matched to the actual needs of the analyzer, which affects the analyzer's processing speed.

[0004] In summary, how to effectively improve the sample processing speed of an analytical instrument is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0024] Preferably, the annular track includes a left switching disk, a right switching disk, a horizontally arranged first channel, and a second channel opposite to the first channel. The first channel is arranged on the side close to the analysis device. The left ends of the first channel and the second channel are both arc-shaped transitions and are provided with the left switching disk.

The stopping motor, the first limit sensor, and the second limit sensor are all connected to the control device.

[0030] Preferably, the sorting tray includes a to-be-tested area for receiving sample tubes to be tested and a recycling area for receiving sample tubes that have completed the test. Both the to-be-tested area and the recycling area are provided with a plurality of receiving holes for accommodating sample tubes, and each receiving hole is provided with a receiving label. The control device is used to record the project information to which the sample tube belongs and the corresponding receiving label.

[0031] Preferably, the sample chamber includes a sample loading board for placing sample tubes to be tested and a recycling board for placing sample tubes that have completed the test; or the sample chamber only includes one sample loading board. <X

[0032] When using the single-tube cyclic and orderly sample injection system provided by the present invention, first, a plurality of sample tubes to be tested can be placed in the sample chamber, and then the first handling device is controlled to operate to move the sample tube to the code scanning device located between the sample chamber and the sorting tray. The code scanning device can perform code scanning and identification on the sample tube to confirm the project to which the sample tube belongs. Then, the first handling device places the sample tube after code scanning and identification into the sorting tray, and the control device can record the project information to which the sample tube belongs and the position information of the sample tube in the sorting tray in real time.

[0033] Meanwhile, the control device can detect and analyze the usage of the analysis device in real time to facilitate the determination of subsequent control operations. When the analysis device includes only one analyzer, the control device controls the second handling device to continuously pick up sample tubes of the same item from the sorting tray to the tube seat member. After all the sample tubes of the same item have been analyzed, the analyzer can reset the test conditions for item switching. Then, the control device controls the second handling device to continuously pick up sample tubes of another item from the sorting tray to the tube seat member. Subsequently, the above operations are repeated, thereby effectively reducing the item switching frequency of the analysis device;

[0034] When the analysis device includes multiple analyzers, the control device can control the second handling device according to the vacancy situation of the analyzers, so that the second handling device picks up the sample tubes of the corresponding items to the tube seat member. For example, when there is a vacancy in the first analyzer of the analysis device, the control device can control the second handling device to pick up the sample tubes of the corresponding items from the sorting tray to the first analyzer; when the first analyzer is performing detection and analysis and there is a vacancy in the second or third analyzer, the control device can control the second handling device to pick up the sample tubes of the corresponding items from the sorting tray to the second or third analyzer. Therefore, the same analyzer can continuously detect and analyze the samples of the same item, and there is no need to reset the test conditions during this process, which can effectively improve the sample processing speed of the analysis instrument.

[0035] Then, the control device can control the conveyor belt to run, so that the tube seat member carries the sample tubes and moves along the circular track. When the sample tube moves to the sampling position and the detector detects that there is a sample tube placed on the tube seat member, the control device can control the stop device at the sampling position to run to pause the movement of the tube seat member. Subsequently, the control device can control the positioning device to run to clamp and fix the sample tube. Then, the sampling mechanism of the analysis device can suck the sample liquid from the sample tube to the analyzer to realize the detection and analysis operation of the sample tube.

[0036] During this period, when the sample liquid sucking operation is completed, the control device can control the positioning device to release the sample tube and control the stop device to run in the reverse direction, so that the tube seat member can continue to move forward. When the tube seat member moves to the initial position, the control device can control the second handling device to run to pick up the measured sample tube from the conveying device back to the sorting tray. Finally, the control device controls the first handling device to run to pick up the sample tube from the sorting tray to the sample chamber, thereby completing the detection operation of the sample tube.

[0037] Since the system classifies the sample tubes, can selectively grab the sample tubes according to the vacancies of the analyzer, and perform transportation and aspiration operations on individual sample tubes, the same analyzer can continuously detect and analyze the samples of the same item, and the test conditions do not need to be reset during this process, which can effectively improve the sample processing speed of the analytical instrument. That is to say, the sample injection method of this system is flexible and can well match the actual needs of the analyzer to improve the processing speed of the analyzer.

[0038] In summary, the single-tube circulating and orderly sample injection system provided by the present invention can effectively improve the sample processing speed of the analytical instrument. Brief Description of the Drawings

Detailed implementation manners

[0058] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0059] The core of the present invention is to provide a single-tube circulating and orderly sampling system, which can effectively improve the sample processing speed of analytical instruments.

[0060] Please refer to Figures 1 to 16 。

[0061] This specific embodiment provides a single-tube circulating and orderly sampling system, including:

[0062] A sample chamber 1 for placing a plurality of sample tubes 2 to be measured or already measured;

[0063] A classification tray 3 for placing sample tubes 2 of different items;

[0064] A barcode scanning device 4 for scanning and identifying the sample tube 2 to confirm the item to which the sample tube 2 belongs. The barcode scanning device 4 is provided between the sample chamber 1 and the classification tray 3;

[0065] An analysis device 5, including one or more analyzers 52 for detecting and analyzing sample tubes 2 of different items;

[0066] A conveying device 6, which includes an annular track 61, a tube seat member 62 for accommodating a single sample tube 2, and a conveyor belt 63 for driving the tube seat member 62 to move cyclically along the annular track 61. On one side of the annular track 61 close to the analysis device 5, there is a sampling position 64. The sampling position 64 is provided with a detector 65 for detecting whether a sample tube 2 is placed on the tube seat member 62, a stop device 66 for pausing the movement of the tube seat member 62, and a positioning device 67 for clamping or loosening the sample tube 2. The analysis device 5 is provided with a sampling mechanism 51 for sucking the sample liquid from the sampling position 64 to the analyzer 52;

[0067] A first handling device 7 for driving the sample tube 2 to be transferred between the sample chamber 1 and the classification tray 3;

[0068] A second handling device 8 for driving the sample tube 2 to be transferred between the classification tray 3 and the conveying device 6; <s

[0069] A control device. The barcode scanning device 4, the analysis device 5, the conveying device 6, the sampling mechanism 51, the first handling device 7, and the second handling device 8 are all connected to the control device.

[0070] It should be noted that the first handling device 7 can be set as a three-dimensional coordinate handling robot, which can move in the X-axis direction, Y-axis direction, and Z-axis direction. The second handling device 8 can be set as a rotary handling robot. By rotating the moving angle, the sample tube 2 on the sorting tray 3 can be transferred to the initial sample position of the annular track 61. Then, the sample tube 2 can flow and be transported within the annular track 61. Moreover, this system adopts the form of single-tube sampling, and the sample tube 2 can be sent into the analyzer 52 one by one for detection according to the actual sampling requirements of the analyzer 52.

[0071] During the actual operation process, according to the actual situation and actual requirements, the shapes, structures, dimensions, materials, positions, etc. of the sample chamber 1, sorting tray 3, code scanning device 4, analysis device 5, conveying device 6, first handling device 7, second handling device 8, and control device can be determined.

[0072] When using the single-tube circulating and orderly sampling system provided by the present invention, first, a plurality of sample tubes 2 to be tested can be placed in the sample chamber 1, and then the first handling device 7 is controlled to operate to move the sample tube 2 to the code scanning device 4 located between the sample chamber 1 and the sorting tray 3. The code scanning device 4 can perform code scanning and identification on the sample tube 2 to confirm the item to which the sample tube 2 belongs. Then, the first handling device 7 places the sample tube 2 after code scanning and identification into the sorting tray 3, and the control device can record the item information to which the sample tube 2 belongs and the position information of the sample tube 2 in the sorting tray 3 in real time.

[0073] Meanwhile, the control device can detect the usage situation of the analysis device 5 in real time to facilitate determining subsequent control operations. When the analysis device 5 only includes one analyzer 52, the control device controls the second handling device 8 to continuously grab the sample tubes 2 of the same item from the sorting tray 3 to the tube seat member 62. After all the sample tubes 2 of the same item have been analyzed, the analyzer 52 can reset the test conditions to perform item switching. Then, the control device controls the second handling device 8 to continuously grab the sample tubes 2 of another item from the sorting tray 3 to the tube seat member 62. Subsequently, the above operations are repeated, thereby effectively reducing the item switching frequency of the analysis device 5;

[0074] When the analysis device 5 includes multiple analyzers 52, the control device can control the second handling device 8 according to the vacancy situation of the analyzers 52, so that the second handling device 8 grabs the sample tube 2 of the corresponding item to the tube seat member 62. For example, when there is a vacancy in the first analyzer of the analysis device 5, the control device can control the second handling device 8 to grab the sample tube 2 of the corresponding item from the sorting tray 3 to the first analyzer; when the first analyzer performs detection and analysis, and there is a vacancy in the second analyzer or the third analyzer, the control device can control the second handling device 8 to grab the sample tube 2 of the corresponding item from the sorting tray 3 to the second or third analyzer. Therefore, the same analyzer can continuously detect and analyze samples of the same item, and this process does not require resetting the test conditions, which can effectively improve the sample processing speed of the analytical instrument.

[0075] Then, the control device can control the conveyor belt 63 to run, so that the tube seat member 62 carries the sample tube 2 and moves along the circular track 61. When the sample tube 2 moves to the sampling position 64 and the detector 65 detects that there is a sample tube 2 placed on the tube seat member 62, the control device can control the stop device 66 at the sampling position 64 to run to pause the movement of the tube seat member 62. Subsequently, the control device can control the positioning device 67 to run to clamp and fix the sample tube 2. Then, the sampling mechanism 51 of the analysis device 5 can suck the sample liquid from the sample tube 2 into the analyzer 52 to realize the detection and analysis operation of the sample tube 2.

[0076] During this period, when the operation of sucking the sample liquid is completed, the control device can control the positioning device 67 to release the sample tube 2 and control the stop device 66 to run in the reverse direction, so that the tube seat member 62 can continue to move forward. When the tube seat member 62 moves to the initial position, the control device can control the second handling device 8 to run to grab the measured sample tube 2 from the conveying device 6 back to the sorting tray 3. Finally, the control device controls the first handling device 7 to run to grab the sample tube 2 from the sorting tray 3 to the sample chamber 1, thereby completing the detection operation of the sample tube 2.

[0077] Since this system classifies the sample tubes 2, can selectively grab the sample tubes 2 according to the vacancy situation of the analyzers 52, and performs conveying and sucking operations on individual sample tubes 2, the same analyzer 52 can continuously detect and analyze samples of the same item, and this process does not require resetting the test conditions, which can effectively improve the sample processing speed of the analytical instrument. That is to say, the sampling method of this system is flexible and can well match the actual needs of the analyzer 52 to improve the processing speed of the analyzer 52.

[0078] In summary, the single-tube cyclic and orderly sampling system provided by the present invention can effectively improve the sample processing speed of the analytical instrument.

[0079] On the basis of the above embodiments, preferably, a code scanning position 68 is provided on one side of the annular track 61 close to the analysis device 5, and the code scanning position 68 is located at the front end of the sample injection position 64. The code scanning position 68 is provided with a detector 65, a stopping device 66, a code scanning device 4, and a rotating device 69 for clamping or loosening the sample tube 2. The rotating device 69 can drive the sample tube 2 to rotate. By providing the code scanning position 68 at the front end of the sample injection position 64, it is possible to prevent the tube seat member 62 without the sample tube 2 from moving to the sample injection position 64 for sampling operation, and to avoid the phenomenon of air suction of the sample suction mechanism 51 of the analysis device 5.

[0080] It should be noted that when the tube seat member 62 moves to the code scanning position 68 and the detector 65 detects that the sample tube 2 is placed on the tube seat member 62, the control device can control the operation of the stopping device 66 at the code scanning position 68 to pause the moving process of the tube seat member 62. Then, the control device can control the operation of the rotating device 69 to clamp the sample tube 2 and drive the sample tube 2 to rotate circumferentially. When the sample tube 2 rotates, it can ensure that the code scanning device 4 accurately identifies the sample tube 2.

[0081] If the sample tube 2 is the sample tube 2 required by the analyzer 52, the control rotates the device 69 to loosen the sample tube 2, and controls the stopping device 66 to run in the reverse direction, no longer preventing the movement of the tube seat member 62, so that the tube seat member 62 can continue to move forward. When the sample tube 2 moves to the sample injection position 64 and the detector 65 detects that the sample tube 2 is placed on the tube seat member 62, the control device can control the operation of the stopping device 66 at the sample injection position 64 to pause the movement of the tube seat member 62. Subsequently, the control device can control the operation of the positioning device 67 to clamp and fix the sample tube 2. Then, the sample suction mechanism 51 of the analysis device 5 can suck the sample liquid from the sample tube 2 into the analyzer 52 to realize the detection and analysis operation of the sample tube 2. During this period, when the sample liquid suction operation is completed, the control device can control the positioning device 67 to loosen the sample tube 2 and control the stopping device 66 to run in the reverse direction, so that the tube seat member 62 can continue to move forward.

[0082] If it is determined that the sample tube 2 is not the sample tube 2 required by the analyzer 52, the control rotates the device 69 to loosen the sample tube 2 and controls the stopping device 66 to run in the reverse direction, so that the tube seat member 62 can continue to move forward. And when the tube seat member 62 moves to the sample injection position 64, there is no need to control the components such as the stopping device 66, the positioning device 67, and the sampling needle at the sample injection position 64 to run, so that the tube seat member 62 directly moves forward through the sample injection position 64.

[0083] Preferably, the rotating device 69 includes a first fixing block 691 disposed on one side of the code scanning position 68, a second fixing block 692 disposed on the other side perpendicular to the code scanning position 68, a guiding shaft 693 disposed perpendicular to the first fixing block 691, a slider 694 that can move back and forth along the guiding shaft 693, a reciprocating device 695 for driving the slider 694 to reciprocate, a first bracket 696 horizontally disposed on the slider 694, a driven shaft 697 perpendicularly connected to the first bracket 696, a driven wheel 698 disposed at the bottom end of the driven shaft 697, a fixed-point sensor 699 for detecting whether there is a tube seat member 62 directly in front of the driven wheel 698, a second bracket 6910 horizontally connected to the first bracket 696, a driving shaft 6911 perpendicularly connected to the second bracket 6910, a driving wheel 6912 disposed at the bottom end of the driving shaft 6911, a driving member 6913 for driving the driving wheel 6912 to rotate, an idler shaft 6914 disposed perpendicular to the second fixing block 692, and a driven idler wheel 6915 sleeved on the outer peripheral portion of the idler shaft 6914. The structure is as Figure 8 and Figure 9 shown;

[0084] When the reciprocating device 695 drives the slider 694 to move forward to a preset position, the driving wheel 6912, the driven wheel 698, and the driven idler wheel 6915 can form an isosceles triangle for restricting the position of the tube seat member 62. The reciprocating device 695, the fixed-point sensor 699, and the driving member 6913 are all connected to the control device.

[0085] It should be noted that the fixed-point sensor 699 can be disposed on the annular track 61 between the driven shaft 697 and the driving shaft 6911. When the tube seat member 62 moves to the code scanning position 68 and the detector 65 detects that there is a tube seat member 62 with a sample tube 2 passing through, the control device can control the blocking device 66 to act to intercept the tube seat member 62, and the tube seat member 62 stops moving when it encounters the blocking device 66. Moreover, when the fixed-point sensor 699 detects that there is a tube seat member 62 directly in front of it, the control device can control the reciprocating device 695 to move forward, so that the driving wheel 6912 and the driven wheel 698 cooperate with the driven idler wheel 6915 to press the tube seat member 62, and control the driving member 6913 to operate, so that the driving wheel 6912 performs a rotating action, and then the tube seat member 62 drives the sample tube 2 to rotate circumferentially to ensure that the code scanning device 4 fully scans the sample tube 2. When the code scanning device 4 receives the item information of the sample tube 2, the driving member 6913 stops rotating, the reciprocating device 695 retracts backward, and the blocking device 66 is reset, so that the scanned sample tube 2 and the tube seat member 62 can pass through the code scanning position 68 smoothly.

[0086] Preferably, the reciprocating device 695 includes a driving spring 6951, a cam disk 6952, a cam motor 6953 for driving the cam disk 6952 to rotate, and a cam follower 6954 provided on the cam disk 6952, which is arranged between the first fixed block 691 and the slider 694. The upper half of the cam follower 6954 is in close contact with the lower half of the slider 694, and the structure is as shown in Figure 10 . The driving member 6913 is a synchronous belt drive structure.

[0087] It should be noted that when the cam motor 6953 operates, it can drive the cam disk 6952 to rotate, and the cam follower 6954 can rotate synchronously with the cam disk 6952. When the cam follower 6954 moves from the front end to the rear end, the cam follower 6954 will push the slider 694 backward. When the cam follower 6954 moves from the rear end to the front end, the cam follower 6954 no longer presses the slider 694. At this time, the slider 694 can move forward under the action of the driving spring 6951, so as to realize the reciprocating movement of the slider 694 back and forth.

[0088] It should also be noted that the driving member 6913 is a synchronous belt drive structure, which may include a driving motor 69131, a main synchronous belt pulley 69132 sleeved on the outer peripheral part of the output shaft of the driving motor 69131, a motor mounting plate 69133 for mounting the driving motor 69131, a slave synchronous belt pulley 69134 arranged in cooperation with the main synchronous belt pulley 69132, a driving shaft 6911 for penetrating and connecting the slave synchronous belt pulley 69134 and the driving wheel 6912, a shaft sleeve 69136 and a shaft sleeve limiting piece 69137 sleeved on the outer peripheral part of the driving shaft, a driving synchronous belt 69138 wound around the outer peripheral parts of the main synchronous belt pulley 69132 and the slave synchronous belt pulley 69134, and a tensioning piece 69135 for tensioning the driving synchronous belt 69138. The structure is as shown in Figure 9 . When the driving motor 69131 operates, it can synchronously drive the main synchronous belt pulley 69132, the slave synchronous belt pulley 69134 and the driving wheel 6912 to rotate, and then drive the driven wheel 698, the driven idler pulley 6915, the tube seat part 62, the sample tube 2, etc. to rotate synchronously.

[0089] Preferably, a limit buffer pad 6916 is provided at the front end of the guide shaft 693, a limit switch 6917 is provided at the rear end of the guide shaft 693, a rotary switch 6918 is provided at the first fixed block 691, a rotary tab 6919 for triggering the rotary switch 6918 and a limit tab 6920 for triggering the limit switch 6917 are provided on the slider 694, and both the rotary switch 6918 and the limit switch 6917 are connected to the control device; when the rotary tab 6919 leaves the rotary switch 6918, the control device controls the driving member 6913 to operate, and when the rotary tab 6919 blocks the rotary switch 6918, the control device controls the driving member 6913 to stop operating; when the limit tab 6920 blocks the limit switch 6917, the control device controls the cam motor 6953 to stop operating

[0090] It should be noted that under the elastic force of the driving spring 6951, the driving wheel 6912 and the driven wheel 698 can move forward along the guide shaft 693 simultaneously. When the slider 694 touches the limit buffer pad 6916 at the front end of the guide shaft 693 and stops, the tube seat member 62 is restricted in position by the isosceles triangle formed by the driving wheel 6912, the driven wheel 698, and the driven idler wheel 6915 at this time. And, it can perform a rotation action driven by the driving motor 69131. After the rotation action of the sample tube 2 is completed, the cam motor 6953 can be controlled to operate to press the driving wheel 6912 and the driven wheel 698 back along the guide shaft 693 simultaneously by using the cam follower 6954. When the limit tab 6920 touches the limit switch 6917, the control device controls the cam motor 6953 to stop operating. And, the rotary switch 6918 is used to control the rotation and stop of the driving wheel 6912. When the rotary tab 6919 leaves the rotary switch 6918, the driving wheel 6912 starts to rotate, and when the rotary tab 6919 blocks the rotary switch 6918, the driving wheel 6912 stops rotating.

[0091] On the basis of the above embodiments, preferably, it further includes an emergency tray 9 for placing the sample tubes 2 to be quickly detected and a code scanning device 4 provided at the end of the emergency tray 9. The emergency tray 9 is provided with a plurality of placement holes 91 for placing the sample tubes 2, and each placement hole 91 is provided with a placement label. The control device is used to record the project information of the sample tube 2 and the corresponding placement label.

[0092] It should be noted that the emergency tray 9 can be set as a circular tray, and the second handling device 8 can drive the sample tube 2 to be transferred between the sorting tray 3, the emergency tray 9, and the conveying device 6. After the sample tube 2 is placed on the emergency tray 9, the second handling device 8 is used to rotate to obtain the sample tube 2 and drive the sample tube 2 to perform a code scanning action at the code scanning device 4. The sample tubes 2 in the emergency tray 9 after code scanning can perform the sample injection operation prior to the sample tubes 2 in the sorting tray 3.

[0093] Preferably, the annular track 61 includes a left switching disc 611, a right switching disc 612, a horizontally arranged first channel 613, and a second channel 614 arranged opposite to the first channel 613. The first channel 613 is arranged on the side close to the analysis device 5. The left ends of the first channel 613 and the second channel 614 are both arc-shaped transitions and are provided with the left switching disc 611. The right ends of the first channel 613 and the second channel 614 are both arc-shaped transitions and are provided with the right switching disc 612. The structure is as Figure 2 shown;

[0094] Conveyor belts 63 are arranged below both the first channel 613 and the second channel 614. The left switching disc 611, the conveyor belts 63, and the right switching disc 612 are all driven counterclockwise. The left switching disc 611 and the right switching disc 612 are both provided with notches 615 for driving the tube seat member 62 to rotate. The notches 615 are arranged in cooperation with the arc-shaped transitions to receive or output the tube seat member 62. A plurality of tube seat members 62 and detectors 65 are arranged on the first channel 613 and the second channel 614.

[0095] It should be noted that the annular track 61 receives the sample tube 2 to be processed through the tube seat member 62, performs a rotation and scanning operation on the sample tube 2 before sample injection through the rotating device 69, performs positioning and sample injection on the sample tube 2 through the positioning device 67, and realizes the switching of the tube seat member 62 between the first channel 613 and the second channel 614 through the left switching disc 611 and the right switching disc 612, thereby realizing the cyclic and orderly sample injection operation of a single sample tube 2.

[0096] It should also be noted that, taking the arc-shaped transition at the left end as an example, when the detector 65 of the second channel 614 detects that a tube seat member 62 passes through, the left switching disc 611 can be controlled to complete the track switching action to complete the sample injection process of a single sample tube 2. When the tube seat member 62 runs to the left switching disc 611, the second handling device 8 can first remove the sample tube 2 that has completed the sample injection operation from the tube seat member 62, put the measured sample tube 2 into the sorting tray 3, and then obtain a new sample tube 2 from the sorting tray 3 and put it into the tube seat member 62, and cycle through the above sample injection actions.

[0097] Moreover, when the socket part 62 is detected by the detector 65 in the second channel 614, a certain time delay is provided to ensure that the socket part 62 completely enters the notch 615 of the left switching disc 611. Then, the left switching disc 611 is controlled to operate and perform the action of the switching disc to ensure that the socket part 62 passes through the transition curve 616 between the second channel 614 and the left switching disc 611. When the socket part 62 is detected by the detector 65 in the first channel 613, it indicates that the socket part 62 has successfully passed through the transition curve 616 of the left switching disc 611. At this time, the left switching disc 611 can be controlled to perform a reset action to wait for the next socket part 62. Moreover, the curve angles of the transition curves 616 between the first channel 613 and the left switching disc 611 and between the second channel 614 and the left switching disc 611 are the same, and it is necessary to ensure that the frictional force received by the socket part 62 is greater than the centrifugal force it receives.

[0098] Preferably, both the first channel 613 and the second channel 614 are asymmetric groove-shaped guide rails, and the structure is as Figure 5 shown.

[0099] It should be noted that the socket part 62 is driven by the conveyor belt 63 to move to the notch 615 of the left switching disc 611 or the right switching disc 612. The socket part 62 can enter the notch 615 of the switching disc under the guiding action of the inner docking curve and the outer docking curve of the track and the driving of the frictional force of the conveyor belt 63. Then, the switching disc is controlled to rotate to drive the socket part 62 to complete the track switching action. The socket part 62 has a structure with a limiting groove. By placing the socket part 62 in the asymmetric groove-shaped guide rail, the frictional force of the conveyor belt 63 on the socket part 62 can be increased, preventing the socket part 62 from being thrown out of the notch 615 due to excessive centrifugal force, and effectively preventing the socket part 62 from tipping during transportation.

[0100] Preferably, the detector 65 includes an upper sensor 651 for detecting whether a sample tube 2 is placed on the socket part 62, a lower sensor 652 for detecting whether there is a socket part 62 on the annular track 61, and a fixed bracket 653. The upper sensor 651 is arranged on the upper side of the fixed bracket 653, and the lower sensor 652 is arranged on the lower side of the fixed bracket 653. The structure is as Figure 12 shown.

[0101] It should be noted that when the upper sensor 651 detects that the sample tube 2 is placed on the socket member 62 and the lower sensor 652 detects the presence of the socket member 62, the stop device 66 can be controlled to change from the open state to the closed state. Among them, the open state of the stop device 66 is the state where the stop rod is parallel to the track, and the closed state of the stop device 66 is the state where the stop rod is perpendicular to the track, so as to ensure that the socket member 62 stops moving under the blocking action of the stop device 66. If the lower sensor 652 detects the presence of the socket member 62 and the upper sensor 651 does not detect the sample tube 2, the stop device 66 does not perform the stop action, and other components do not perform actions either, so that the socket member 62 without the sample tube 2 can directly flow backward, so as to avoid operations such as clamping and sampling of the empty socket.

[0102] On the basis of the above embodiments, preferably, the stop device 66 includes a stop mounting plate 661 provided on the annular track 61, a rotatable stop motor 662 provided on the stop mounting plate 661, and a stop rod 663. One end of the stop rod 663 is connected to the rotating end of the stop motor 662, and the other end of the stop rod 663 is used to block the socket member 62. The structure is as Figure 13 shown;

[0103] The stop mounting plate 661 is provided with a first limit sensor 665 and a second limit sensor 666. The first limit sensor 665 is used to detect whether the stop rod 663 moves to a position parallel to the annular track 61, and the second limit sensor 666 is used to detect whether the stop rod 663 moves to a position perpendicular to the annular track 61. The stop motor 662, the first limit sensor 665, and the second limit sensor 666 are all connected to the control device.

[0104] It should be noted that when the stop device 66 needs to perform the stop action, the stop motor 662 can be controlled to operate to drive the stop rod 663 to rotate. When the stop rod 663 rotates to a position perpendicular to the annular track 61, the second limit sensor 666 transmits a stop operation signal to the stop motor 662. At this time, the stop rod 663 can prevent the forward transportation process of the socket member 62, and the end of the stop rod 663 can effectively block the socket member 62.

[0105] When the stop device 66 needs to stop performing the stop action, the stop motor 662 can be controlled to run in the reverse direction to drive the stop rod 663 to rotate in the reverse direction. When the stop rod 663 rotates to a position parallel to the annular track 61, the first limit sensor 665 transmits a stop operation signal to the stop motor 662. At this time, the stop rod 663 will not prevent the forward transportation process of the socket member 62. Among them, a rolling wheel 664 can be provided at the end of the stop rod 663 to avoid abrasion of the socket member 62 by the stop rod 663. A limit rod 667 can be provided at the second limit sensor 666 to ensure that the stop rod 663 will not rotate excessively.

[0106] Preferably, the sorting tray 3 includes a to-be-tested area for receiving the sample tube 2 to be tested and a recycling area for receiving the sample tube 2 that has completed the test. Both the to-be-tested area and the recycling area are provided with a plurality of receiving holes 31 for accommodating the sample tube 2. Each receiving hole 31 is provided with a receiving label, and the control device is used to record the information of the item to which the sample tube 2 belongs and the corresponding receiving label.

[0107] It should be noted that the sorting tray 3 can be set as the to-be-tested area and the recycling area, which enables the sorting tray 3 to meet the two functions of placing and storing the sample tube 2, so as to achieve the purpose of continuous sample injection. Moreover, the recycling area on the sorting tray 3 is specifically used for receiving the sample tube 2 that has completed the sample injection. The sample tube 2 that has completed the sample injection does not need to be stored on the sorting tray 3 and can be directly recycled to the sample loading board card in the sample chamber 1, so as to realize the separate management of the injected samples and the recycled samples.

[0108] It should also be noted that the structure of the sorting tray 3 is not limited to a circular shape, and other styles of structural forms can also be adopted. Moreover, the shape, number, etc. of the receiving holes 31 provided on the sorting tray 3 can be set according to actual needs. This system classifies and places the samples to be injected according to the item categories, stores them, and injects samples according to the actual needs of the analyzer 52. This kind of sample injection method can maximize the use efficiency of the analyzer 52.

[0109] Preferably, the sample chamber 1 includes a sample loading board card for placing the sample tube 2 to be tested and a recycling board card for placing the sample tube 2 that has completed the test; or the sample chamber 1 only includes a sample loading board card.

[0110] It should be noted that when the sample chamber 1 includes a sample loading board card and a recycling board card, sample injection can be cycled and the samples that have completed the sample injection can be recycled. This kind of sample injection form can ensure that the analyzer 52 is always in a working state and maximize the working efficiency of the analyzer 52. When the sample chamber 1 only includes the sample loading board card, the entire sample loading board card can be injected at one time, maximizing the off-line processing. After all the samples are processed, they can all be recycled into the sample loading board card.

[0111] It should be explained that the first handling device 7 and the second handling device 8, the first fixing block 691 and the second fixing block 692, the first channel 613 and the second channel 614, the first limit sensor 665 and the second limit sensor 666 mentioned in this application document. Among them, the first and the second are only used to distinguish different positions and there is no order of priority.

[0112] In addition, it should be noted that the orientation or positional relationship indicated by "up and down", "left and right", etc. in this application is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of simplifying the description and understanding, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.
