Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and specifically relates to a multi-channel high-speed sorting machine. Background Art

[0002] With the progress of science and technology and the continuous improvement of people's health level, clinical testing institutions have to process more and more vacuum blood collection tubes every day. Currently, there are mainly the following methods for sorting samples:

[0003] First, manual sorting: This is also the most common sorting method. An operator holds the blood collection tube by hand for barcode scanning, and then, according to the test items seen from the computer and the classification rules set by the hospital, after manual judgment, the blood collection tube is manually placed into the appropriate container. This sorting efficiency is very low and prone to errors. Once the manually sorted samples are placed in the wrong position, it is very difficult to trace the source.

[0004] Second, the first-generation sorting machine: This is also the most widely used sorting machine in the current market. It can automatically sort blood collection tubes into multiple storage boxes, and the blood collection tubes are in a scattered and free state. Clinical testing institutions still need to arrange manpower to manually transfer the preliminarily sorted blood collection tubes again in order to send the samples to terminal devices such as centrifuges and analyzers. Therefore, this method still has the problem of low efficiency.

[0005] Third, the second-generation sorting machine: Based on the first-generation sorting machine, this type of sorting machine adds a robotic arm, which can insert some blood collection tubes into the centrifuge block or the sample tray, and the degree of automation is improved to a certain extent. However, in order to improve the sorting speed, 2 sets of symmetrical robotic arms and tube arranging devices (the tube arranging device is used to arrange the scattered blood collection tubes collected by clinical testing institutions into an orderly queue of test tubes) are installed in one sorting machine. Limited by the movement stroke range of a single robotic arm, this type of sorting machine often needs to perform secondary sorting and transfer (that is, the 2 sets of robotic arms exchange blood collection tubes) in order to send the blood collection tubes into the final required sample containers. The greater the number of classifications, the greater the probability of secondary sorting and transfer. Therefore, the efficiency of this type of sorting machine is still not high.

[0006] In addition, for the second-generation sorting machine, due to the overly large tube arranging device and the layout limitation that the track can only horizontally transport blood collection tubes, it often has high requirements for the internal space of sorting and the external space of the sorting machine. Even, it requires more than 50 cm of operating space to be reserved in the front, back, left, and right directions of the sorting machine, which is not conducive to popularization and use in clinical testing institutions. Therefore, it is necessary to make improvements. Summary of the Utility Model

[0079] A sorting unit 200 for sorting the blood collection tubes entering from the tube arranging unit 100;

[0080] At least one sorting track 300, into which the blood collection tubes sorted out by the sorting unit 200 enter;

[0082] An intubation unit 500, and the blood collection tubes on the sorting track 300 are inserted onto the intubation unit 500 through the robotic arm unit 400.

[0083] A sample scattering unit 600 for storing and placing the blood collection tubes dropped from the sorting track 300;

[0084] It further includes a tube dropping unit 700, which is arranged on the side of the corresponding sorting track 300 and performs a tube dropping action on the blood collection tubes thereon, so that the blood collection tubes enter the sample scattering unit 600.

[0085] In this embodiment, as Figures 1 - 7 shown, there are three sorting tracks 300. The blood collection tubes sorted by the sorting unit 200 enter the corresponding sorting tracks 300 for transportation. One of the sorting tracks 300 is used in cooperation with the tube inserting unit 700, and the other two sorting tracks 300 are used in cooperation with the robotic arm unit 400. The sorting track 300 cooperating with the tube inserting unit 700 keeps the blood collection tubes on it in a horizontal state. The sorting track 300 cooperating with the robotic arm unit 400 keeps the blood collection tubes on it in a vertical state. The structures of the three sorting tracks 300 are the same, and the difference is that the size of the conveying channel of the sorting track 300 cooperating with the tube inserting unit 700 is smaller than the size of the conveying channel of the sorting track 300 cooperating with the robotic arm unit 400.

The movable end of the tube inserting power part 7001 is movably connected to one end of the swing piece 7002.

It should be noted that the blood collection tubes on the sorting track 300 corresponding to the tube inserting unit 700 are in a horizontal state, that is, the blood collection tubes are placed horizontally on the conveying channel, and after being blocked by the swing piece 7002, they can quickly enter the sample scattering unit 600. Each tube inserting unit 700 corresponds to a sensor, and the corresponding tube inserting unit 700 acts by sensing the arrival of the blood collection tube.

The first conveyor belt 3002 and the second conveyor belt 3003 respectively cooperate with the driving pulley 3006. When the conveying power unit 3005 works, it drives the driving pulley 3006 to rotate, and then drives the first conveyor belt 3002 and the second conveyor belt 3003 to act synchronously;

[0091] The size of the conveying channel of the sorting track 300 that cooperates with the robotic arm unit 400 is smaller than the size of the tube cap of the blood collection tube and larger than the tube diameter of the blood collection tube, so that the corresponding blood collection tube is conveyed on the corresponding sorting track 300 in a vertical state;

[0092] The size of the conveying channel of the sorting track 300 that cooperates with the tube feeding unit 700 is smaller than the tube diameter of the blood collection tube, so that the corresponding blood collection tube is conveyed on the corresponding sorting track 300 in a horizontal state.

[0095] Specifically, the tube clamping unit 800 includes a tube clamping support 8001, on which a first clamping piece 8002 and a second clamping piece 8003 are slidably connected. The first clamping piece 8002 and the second clamping piece 8003 move relative to each other. A number of first half grooves 8004 are arranged at intervals on the first clamping piece 8002, and a number of second half grooves 8005 are arranged at intervals on the second clamping piece 8003. When the first clamping piece 8002 and the second clamping piece 8003 are fitted together, the first half grooves 8004 cooperate with the corresponding second half grooves 8005 to form a tube clamping channel adapted to the blood collection tube; Tube clamping sliders 8006 are respectively arranged at the bottoms of the first clamping piece 8002 and the second clamping piece 8003, and the tube clamping sliders 8006 cooperate with tube clamping guide rails 8007 arranged on the tube clamping support 8001; The first clamping piece 8002 and the second clamping piece 8003 can slide relative to the tube clamping support 8001 respectively through the cooperation of the tube clamping sliders 8006 and the tube clamping guide rails 8007;

[0096] The tube clamping unit 800 further includes a tube clamping motor 8008 connected to the tube clamping support 8001 and a tube clamping driven pulley 8009 rotatably connected to the tube clamping support 8001. The tube clamping driven pulley 8009 and the tube clamping motor 8008 are arranged at intervals; A tube clamping driving pulley 80010 is connected to the movable end of the tube clamping motor 8008, and the tube clamping driving pulley 80010 and the tube clamping driven pulley 8009 are connected by a tube clamping synchronous belt 80011;

[0097] The first clamping piece 8002 is connected to one side of the tube clamping synchronous belt 80011 through a first connecting plate 80012, and the second clamping piece 8003 is connected to the other side of the tube clamping synchronous belt 80011 through a second connecting plate 80013, so that the moving direction of the first clamping piece 8002 is opposite to that of the second clamping piece 8003.

[0098] When the tube clamping motor 8008 runs clockwise, the first clamping piece 8002, the second clamping piece 8003 and the partition plate 80014 open at the same time, and the blood collection tube can pass through. When the tube clamping motor 8008 runs counterclockwise, the first clamping piece 8002, the second clamping piece 8003 and the partition plate 80014 tighten at the same time. After the first clamping piece 8002 and the second clamping piece 8003 are tightened, the tube clamping channel cooperates with the blood collection tube, so as to separate multiple blood collection tubes, make the blood collection tubes in a vertical state and positioned. The partition plate 80014 at the top is used to separate the subsequent blood collection tubes.

[0099] In an embodiment, the tube clamping unit 800 further includes a partition plate 80014, which is connected to the first clamping piece 8002 and the second clamping piece 8003 to separate the blood collection tubes outside the tube clamping unit 800.

[0100] In this embodiment, as Figures 1 - 3 andFigure 10 As shown, the tube arranging unit 100 includes a tube arranging bin 1001, a tube arranging track 1002 and an intermediate transmission unit 1003. The opening of the tube arranging bin 1001 is provided with a material cover, and the material cover is equipped with an automatic induction sensor, which facilitates the operator to operate without hands when holding the vacuum blood collection tube container with both hands, and automatically opens and closes the material cover of the tube arranging bin; the intermediate transmission unit 1003 transports the blood collection tubes in the tube arranging bin 1001 to the tube arranging track 1002, and enters the sorting unit 200 through the tube arranging track 1002;

[0101] The intermediate transmission unit 1003 includes an intermediate support frame 10031. The intermediate support frame 10031 is arranged obliquely. The bottom of the intermediate support frame 10031 is located inside the tube arranging bin 1001, and the top of the intermediate support frame 10031 is higher than the conveying surface of the tube arranging track 1002. The blood collection tubes fall onto the tube arranging track 1002 by gravity;

[0102] Driven rollers 10032 are respectively arranged at the upper and lower ends of the intermediate support frame 10031. A tube arranging conveyor belt 10033 is connected between the two driven rollers 10032. A plurality of tube arranging stoppers 10034 are arranged at intervals on the outer surface of the tube arranging conveyor belt 10033. The height of the tube arranging stoppers 10034 is higher than the diameter of the tube cap of the blood collection tube, so that the tube arranging stoppers 10034 can transport the blood collection tubes located in the tube arranging bin 1001 to the tube arranging track 1002 through the intermediate transmission unit 1003; Tooth grooves are arranged at intervals on the tube arranging stoppers 10034, which cooperate with the groove part 10011 at the inner bottom of the tube arranging bin 1001. When the blood collection tube enters this position, the tube arranging stoppers 10034 can carry the blood collection tube, as Figure 11 shown;

[0103] A tube arranging power unit 10035 is also arranged on the intermediate support frame 10031. The tube arranging power unit 10035 is a motor, which is a prior art and will not be elaborated here; The movable end of the tube arranging power unit 10035 is connected with a driving roller 10036. The driving roller 10036 cooperates with the inner surface of the tube arranging conveyor belt 10033. Driven by the tube arranging power unit 10035, the tube arranging conveyor belt 10033 reciprocates on the intermediate support frame 10031, continuously transporting the blood collection tubes in the tube arranging bin 1001 to the tube arranging track 1002;

[0104] The bottom of the intermediate transmission unit 1003 is located at the inner bottom of the tube arranging bin 1001. After the blood collection tubes enter the tube arranging bin 1001, the tube arranging stoppers 10034 carry the blood collection tubes in a horizontal state, and are transported under the action of the intermediate transmission unit 1003.

[0105] In this embodiment, as Figure 10As shown, the tube sorting track 1002 includes a tube sorting bracket 10021. A third conveyor belt 10022 and a fourth conveyor belt 10023 which are arranged at intervals are movably connected to the tube sorting bracket 10021. A conveying channel for blood collection tubes is formed between the third conveyor belt 10022 and the fourth conveyor belt 10023. The third conveyor belt 10022 and the fourth conveyor belt 10023 are respectively matched with a number of driven wheels 10024 arranged on the tube sorting bracket 10021; the number of driven wheels 10024 are rotationally connected to the tube sorting bracket 10021 through axles;

[0106] It further includes a transmission power unit 10025 arranged on the tube sorting bracket 10021. The transmission power unit 10025 is a motor, which is a prior art and will not be elaborated here; the movable end of the transmission power unit 10025 is connected with a driving wheel 10026. The third conveyor belt 10022 and the fourth conveyor belt 10023 are respectively matched with the driving wheel 10026. When the transmission power unit 10025 works, it drives the driving wheel 10026 to rotate, and then drives the third conveyor belt 10022 and the fourth conveyor belt 10023 to move synchronously;

[0107] The size of the conveying channel for blood collection tubes formed between the third conveyor belt 10022 and the fourth conveyor belt 10023 is smaller than the size of the tube cap of the blood collection tube and larger than the tube diameter of the blood collection tube, so that the corresponding blood collection tube is conveyed on the corresponding tube sorting track 1002 in a vertical state;

[0108] A guiding inclined block 10027 is arranged at the feeding end of the tube sorting track 1002. As Figure 2 shown, the blood collection tubes falling from the top of the intermediate transmission unit 1003 enter the tube sorting track 1002 through the guiding inclined block 10027, preventing the blood collection tubes from falling outside the tube sorting track 1002; as an example, there are two groups of guiding inclined blocks 10027, and the two groups of guiding inclined blocks 10027 are symmetrically arranged on the tube sorting track 1002.

[0109] After the blood collection tubes are poured into the tube sorting bin 1001, the tube sorting bin 1001 will drive the tube sorting conveyor belt 10033 to run upward through the tube sorting power unit 10035, so as to convey the blood collection tubes to be sorted upward to the tube sorting track 1002; the tube sorting conveyor belt 10033 is annular, and is provided with tooth-shaped tube sorting stoppers 10034, which are matched with the groove part at the bottom of the tube sorting bin 1001 and cooperate with the guiding inclined block 10027 of the tube sorting track 1002, which can shorten the distance between the blood collection tubes and the tube sorting track and avoid phenomena such as tube jamming of the blood collection tubes.

[0110] The guiding inclined blocks 10027 on both sides are used to guide the blood collection tubes into the tube arranging track 1002. The blood collection tubes enter the tube arranging track 1002 and are arranged vertically one by one by gravity. The tube part of the blood collection tube is located below the conveying channel, and the tube cap of the blood collection tube is located above the conveying channel, so that the blood collection tubes are in a vertical state. The third conveyor belt 10022 and the fourth conveyor belt 10023 are driven simultaneously by the transmission power unit 10025 to convey the blood collection tubes in a vertical state. The end of the tube arranging track is open, and the blood collection tubes are conveyed to the sorting unit 200.

[0111] In this embodiment, as Figures 16 - 23 shown, the sorting unit 200 includes a support part 2001. The support part 2001 includes a base 20011 and a mounting plate 20012 located above the base 20011; a top plate 20014 is connected to the mounting plate 20012 through a plurality of connecting columns 20013;

[0112] The rotating unit 2002 is connected to the supporting part 2001; the rotating unit 2002 includes a rotating power part 20021, a rotating support 20022 and a rotating disk 20023, the rotating power part 20021 is connected to the base 20011; the rotating support 20022 is detachably connected to the base 20011; a sleeve part 20024 is rotatably connected to the rotating support 20022 through a rotating part. As an example, the rotating part is a bearing, and the upper and lower ends of the sleeve part 20024 are respectively connected to the rotating support 20022 through bearings; the rotating disk 20023 is connected to the upper end of the sleeve part 20024, and a passive connecting part 200241 is formed on the outer wall of the sleeve part 20024. As an example, the passive connecting part 200241 is an annular tooth groove; the rotating power part 20021 is a motor with an encoder, which is a prior art and will not be elaborated here; the output end of the rotating power part 20021 is matched with the sleeve part 20024. When the rotating power part 20021 works, it drives the sleeve part 20024 to rotate, thereby realizing the rotation of the rotating disk 20023; the output end of the rotating power part 20021 is connected with an active connecting part 200211, and the active connecting part 200211 is used in cooperation with the passive connecting part 200241. As an example, the passive connecting part 200241 is an annular tooth groove, and the active connecting part 200211 is an active gear matched with the annular tooth groove. For the convenience of structural layout, the active gear and the annular tooth groove are connected through a synchronous belt 200242 to realize the transmission between the active gear and the annular tooth groove; the rotating disk 20023 is located inside the mounting plate 20012 and below the top plate 20014; there is a preset gap between the rotating disk 20023 and the mounting plate 20012, so that the mounting plate 20012 does not interfere with the rotation of the rotating disk 20023; the mounting plate 20012 also serves as a limit for the blood collection tube 2003, so that the corresponding blood collection tube 2003 will not fall out of the fitting groove 200231;

[0113] The rotating disk 20023 is circular, and a number of fitting grooves 200231 adapted to the blood collection tube 2003 are formed at intervals on its edge. The notch of the fitting groove 200231 is chamfered to facilitate the blood collection tube 2003 to enter the corresponding fitting groove 200231. The tube cap of the blood collection tube 2003 entering the fitting groove 200231 is located above the fitting groove 200231, and the size of the tube cap of the blood collection tube 2003 is larger than the size of the fitting groove 200231, so that the blood collection tube 2003 will not fall out of the fitting groove 200231;

[0114] The mounting plate 20012 of the support part 2001 is provided with an introduction slideway 200121 and at least one track distribution slideway 200122. The introduction slideway 200121 is matched with the tube arranging track 1002, and the blood collection tubes coming out of the tube arranging track 1002 enter the introduction slideway 200121;

[0115] When there are two or more track distribution slideways 200122, the intervals of the two or more track distribution slideways 200122 are arranged; the introduction slideway 200121 serves as a channel for sending the blood collection tube 2003 onto the corresponding mating groove 200231, and the track distribution slideway 200122 serves as a channel for pushing the blood collection tube 2003 out of the corresponding mating groove 200231.

[0116] In this embodiment, there are three track distribution slideways 200122, so that different blood collection tubes 2003 enter the preset track distribution slideways 200122 to enter the next process; one of the track distribution slideways 200122 is matched with the sorting track 300 that is matched with the tube throwing unit 700, and the other two track distribution slideways 200122 are matched with the sorting track 300 that is matched with the robotic arm unit 400, that is, the blood collection tubes coming out of the track distribution slideway 200122 enter the corresponding sorting track 300;

[0117] The outlet end of the introduction slideway 200121 is higher than the upper surface of the notch of the mating groove 200231, so as to facilitate the blood collection tube 2003 entering from the introduction slideway 200121 to directly reach the corresponding mating groove 200231; the inlet end of the track distribution slideway 200122 is lower than the upper surface of the notch of the mating groove 200231, or the inlet end of the track distribution slideway 200122 is flush with the upper surface of the notch of the mating groove 200231, which is convenient for the blood collection tube 2003 to enter the track distribution slideway 200122; a buffer block 20015 is provided on the top plate 20014 or the mounting plate 20012 of the support part 2001, and the buffer block 20015 is located directly opposite to the introduction slideway 200121, and is used for auxiliary alignment when the blood collection tube 2003 enters the corresponding mating groove 200231.

[0118] It further includes a tube pushing unit 2004. The tube pushing unit 2004 is connected to the top plate 20014 of the support part 2001. The tube pushing unit 2004 pushes the corresponding blood collection tube 2003 from the mating groove 200231 onto the corresponding track distribution slideway 200122, and the corresponding blood collection tube 2003 enters the corresponding process through the corresponding track distribution slideway 200122; one track distribution slideway 200122 corresponds to one tube pushing unit 2004.

[0119] In an embodiment, as Figure 21As shown, the push tube unit 2004 includes a push-pull power part 20041 connected to the top plate 20014 of the support part 2001. The push-pull power part 20041 is an electric telescopic rod, which is a prior art and will not be elaborated here. The movable end of the push-pull power part 20041 is connected to a push rod 20042. When the movable end of the push-pull power part 20041 is in the extended state, the push rod 20042 is directly opposite to the entrance end of the corresponding track distribution slideway 200122 and is located behind the blood collection tube 2003, facilitating the pushing of the corresponding blood collection tube 3 into the corresponding track distribution slideway 200122.

[0120] In one embodiment, the push tube unit 2004 further includes a mounting support plate 20043. The push-pull power part 20041 is connected to the top plate 20014 of the support part 2001 through the mounting support plate 20043. A relief groove 20044 is provided on the mounting support plate 20043, and the push rod 20042 moves in the relief groove 20044.

[0121] Since the orientation of the barcode information surface is randomly uncertain when the blood collection tube enters the rotary disk, it is necessary to axially rotate the blood collection tube to ensure that the barcode information can be completely read by the scanner. Therefore, a first blood collection tube rotation drive unit 2005 is designed. The first blood collection tube rotation drive unit 2005 includes a rotation drive part 20051 provided on a rotation support member 20022 of the support part 2001. The rotation drive part 20051 is a rotation motor, which is a prior art and will not be elaborated here. The rotation drive part 20051 is connected to the rotation support member 20022 through a connection plate 20052. The rotation drive part 20051 is located inside the blood collection tube 2003, and the movable end of the rotation drive part 20051 is connected to a rotation roller 20053 for driving the blood collection tube 2003 to axially rotate. The blood collection tube is driven to rotate by the rotational force so that the scanner can scan the code on the blood collection tube. A rubber material with a relatively large friction coefficient may be provided on the rotation roller to increase the friction between the blood collection tube and the rotation roller and ensure the stability of the blood collection tube during rotation.

[0122] The first blood collection tube rotation drive unit 2005 further includes a first auxiliary runner 20054 and a second auxiliary runner 20055 arranged at intervals. The first auxiliary runner 20054 and the second auxiliary runner 20055 are respectively rotatably connected to the mounting plate 20012 of the support part 2001. The rotation roller 20053, the first auxiliary runner 20054, and the second auxiliary runner 20055 cooperate to form a rotation space for axially rotating the blood collection tube 2003. When the blood collection tube 2003 enters this rotation space, it drives the blood collection tube to rotate so that the scanner can scan the code on the blood collection tube. It should be noted that when the code position is within a reasonable range, it will not be rotated.

[0123] To facilitate operation of the first blood collection tube rotation drive unit 2005, clearance spaces are formed on the front and rear sides of the mating groove 200231 of the rotating disk 20023. This allows the wall of the blood collection tube 2003 located in the mating groove 200231 to be exposed outside the mating groove 200231. Since the blood collection tube 2003 is connected to the upper surface of the mating groove 200231 through its tube cap, the relative connection of the blood collection tube 2003 is achieved. The clearance spaces do not affect the position of the blood collection tube 2003 in the mating groove 200231. The clearance spaces enable the rotating roller 20053, the first auxiliary rotating wheel 20054, and the second auxiliary rotating wheel 20055 to cooperate with the wall of the blood collection tube 2003, thereby facilitating rotation.

[0124] Furthermore, it also includes a linkage plate 20056, and the first auxiliary rotating wheel 20054 and the second auxiliary rotating wheel 20055 are respectively rotatably connected to the linkage plate 20056; the mounting plate 20012 is connected to a fixed seat 20057, and the fixed seat 20057 is connected to at least two guide rods 20058, which has good stability. The linkage plate 20056 is movably inserted into the guide rod 20058, and the guide rod 20058 is inserted with an elastic member 20059, and the elastic member 20059 is a spring. The elastic member 20059 is located between the linkage plate 20056 and the fixed seat 20057. The elastic member 20059 squeezes the linkage plate 20056, so that the first auxiliary rotating wheel 20054 and the second auxiliary rotating wheel 20055 fit the outer wall of the blood collection tube 2003.

[0125] In one embodiment, if Figure 23 As shown, the blood collection tube height determination unit 2006 is also included. The blood collection tube height determination unit 2006 includes a connecting frame 20061 connected to the base 20011 of the support portion 2001. Three sensors 20062 are spaced apart on the connecting frame 20061. The three sensors 20062 are located at different distances from the base 20011. The sensors 20062 are used to sense whether a blood collection tube 2003 is present in the corresponding matching slot 200231, or to determine the height specification of the blood collection tube 2003 in the corresponding matching slot 200231. The presence or specification of the blood collection tube can be determined based on the sensor signal, thereby allocating the final sorting destination of the blood collection tube. It should be noted that the structure and operating principle of the sensor 20062 are prior art and will not be further described here. For example, the position of the centrifugal block tray of different testing devices is different, which has certain restrictions on the height of the blood collection tubes to be inserted for testing. Generally speaking, blood collection tubes of different heights cannot be mixed and inserted into the centrifugal block tray of the same testing device.

[0126] In one embodiment, if Figure 16As shown, it further includes a scanning unit 2007. The scanning unit 2007 includes a mounting bracket 20071. The mounting bracket 20071 is connected to the top plate 20014 of the support part 1. A scanner 20072 is connected to the mounting bracket 20071. After the blood collection tube height judgment unit 2006 determines the blood collection tube, the scanner 20072 reads the information on the blood collection tube 2003 and decides which track distribution chute 200122 the blood collection tube 2003 enters. It should be noted that the structure and working principle of the scanner 20072 are prior art and will not be elaborated here.

[0127] In one embodiment, as Figure 16 shown, it further includes a coding rotary drive unit 2008 for spraying corresponding codes on the blood collection tube 2003 to help the personnel of clinical testing institutions quickly identify the ownership and serial number of the test tube. It should be noted that the composition of the code and the corresponding information are prior art and will not be elaborated here; the coding rotary drive unit 2008 is arranged on the rotary support 20022 of the support part 2001. The coding rotary drive unit 2008 includes a coder and a second blood collection tube rotary drive unit. The structure of the second blood collection tube rotary drive unit is the same as that of the first blood collection tube rotary drive unit 2005, except for the position. The second blood collection tube rotary drive unit axially rotates the blood collection tube, and the coder sprays corresponding codes on the surface of the blood collection tube. It should be noted that the structure and working principle of the coder are prior art and will not be elaborated here.

[0128] After the blood collection tube height judgment unit determines the blood collection tube, this scanning unit 2007 starts to work, reads the information on the blood collection tube and finally decides which track distribution chute 200122 the blood collection tube enters; according to the information determined by the scanning device, the blood collection tube is pushed into the corresponding track distribution chute 200122 through the push tube unit 2004 respectively.

[0129] The function of the sorting tray in this embodiment is to mix the sample blood collection tubes through the introduction chute 200121, drive the rotary disk 20023 with sixteen workstations to rotate periodically by the rotary unit 2002 composed of a motor with an encoder. Structures such as blood collection tube height judgment, blood collection tube barcode scanner, coding and printing, and track distribution chute are designed at corresponding positions respectively, and mechanisms such as blood collection tube rotary drive and push tube are designed at the positions of scanning, coding and printing, and each track channel respectively, so as to realize the accurate and orderly actions of blood collection tube height judgment, scanning, coding and printing, and track distribution, and complete the sorting of samples.

[0130] This sorting tray provides multiple test tube buffer positions after scanning the barcodes of blood collection tubes. When sending information to the hospital's laboratory information system to obtain the test items of the blood collection tubes in order to determine the sorting channels, the sorting tray can still keep rotating and running, continue the subsequent barcode scanning actions of the blood collection tubes, and will not affect the total sorting processing time due to the time difference of network query waiting, ensuring the high-efficiency operation of the sorting system; on the sorting tray, there is one or more structures with the functions of rotating test tubes and inkjet printing; it is equipped with a high and low tube identification sensor, which can pre-allocate the final distribution tracks of the blood collection tubes to avoid inserting blood collection tubes with different heights into the same centrifuge block tray.

[0131] In this embodiment, as Figure 1 and Figure 2 shown, there are two groups of robotic arm units 400, which are arranged at intervals above the intubation unit 500, and clamp the blood collection tubes on the sorting track 300 and place them on the intubation unit 500.

The output end of the Y-direction driving part 40023 is connected to one end of the Y-direction screw. When the Y-direction driving part 40023 works, it drives the Y-direction screw to rotate, and then drives the Y-direction screw block to move on the Y-direction screw; as an example, a main transmission pulley is connected to the output end of the Y-direction driving part 40023, and a driven transmission pulley is connected to one end of the Y-direction screw. The main transmission pulley and the driven transmission pulley are connected by a transmission belt; in order to ensure the stability during the movement, a Y-direction guide rail is provided on the Y-direction support 40021, and a Y-direction slider that cooperates with the Y-direction guide rail is provided on the Y-direction screw block;

[0138] As Figure 14 and Figure 15 shown, the structure of the second clamping assembly 40043 is the same as that of the first clamping assembly 40042.

The blood collection tubes on them do not rely on the robotic arm. n is a positive integer, n > 2, and they can be directly sent into the sample dispensing unit 600 through the tube feeding unit 700, realizing high-speed sorting and providing a large number of sorting channels.
