Description
Technical Field

Furthermore, existing track-based sample units have limited automation, lacking flexible sample allocation and the ability to retest original sample tubes.
[0003] In addition, when it is necessary to perform multi-indicator testing on a single sample, the existing conditions can only realize that the sample can only be tested on the current testing instrument and then manually sent to another testing instrument for testing of another indicator, or multiple sample tubes can be used at the same time and sent to different testing instruments for testing. The degree of automation is low, and multiple sample tubes are required for the same sample, resulting in a large demand for testing consumables. Therefore, it is necessary for those skilled in the art to solve the problem of automated testing of the same sample on different testing instruments. Utility Model Content

[0048] The present application will be further described in detail below with reference to the accompanying drawings. In the description of the embodiments, unless otherwise stated, the terms "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and are not intended to indicate or imply that the present application must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present application.
[0049] like Figure 1-Figure 3 As shown, this utility model provides a multifunctional sample detection and transmission track, mainly including a base 100, on which a first mounting platform is provided; and a first conveying track 101, which is set on the first mounting platform of the base 100. In this embodiment, in order to facilitate the installation of various components, a bracket is set on the first mounting platform, and the first conveying track 101 is set on the bracket, so that a certain space is left between the first conveying track 101 and the first mounting platform for the installation of transmission components. The first conveying track 101 is used for the transmission of the sample tube group to be tested by the current detection instrument. In this embodiment, the sample tube group includes a sample rack and multiple sampling tubes set on the sample rack.
[0050] A loading platform 103 is located on one side of the first conveying track 101 and is connected to the first conveying track 101. This allows the sample tube assembly to be pushed from the loading platform 103 onto the first conveying track 101. The loading platform 103 is used to place the sample tube assembly of the current testing instrument before sampling and testing. To facilitate the movement of the sample tube assembly from the loading platform 103 to the first conveying track 101, a first reciprocating pushing block 1058 is provided above the loading platform 103. Figure 1 and Figure 5 As shown, the first pushing block 1058 pushes the sample tube assembly onto the first conveying track 101. In this embodiment, the moving direction of the first pushing block 1058 is perpendicular to the conveying direction of the first conveying track 101. In this embodiment, to facilitate the sample tube assembly's linear movement towards the first conveying track 101, the width of the loading platform 103 is adapted to the length of the sample rack of the sample tube assembly. Simultaneously, a loading limit stop is provided on the side of the loading platform 103 to prevent the sample rack from moving in the direction perpendicular to the loading platform 103. In this embodiment, a first trigger switch 1071 is provided on one side of the first conveying track 101, such as... Figure 12 As shown, when the sample tube group touches the first trigger switch 1071, the first conveying track 101 conveys the sample.
[0051] A feeding platform 104 is located on one side of the first conveying track 101, on the same side as the loading platform 103. The feeding platform 104 is connected to the first conveying track 101 so that sample tubes after sampling can be pushed from the first conveying track 101 onto the feeding platform 104. The feeding platform 104 is used for temporary storage or transfer of sample tubes after sampling to the next testing instrument. A second pushing block 601 capable of reciprocating linear movement is provided above the first conveying track 101. Figure 2 and Figure 15 As shown, the second pushing block 601 can push the sample tube assembly located on the first conveying track 101 onto the unloading platform 104. In this embodiment, the moving path of the second pushing block 601 is perpendicular to the conveying path of the first conveying track 101. In this embodiment, to facilitate the sample tube assembly to move only in a straight line from the first conveying track 101 to the unloading platform 104, the width of the unloading platform 104 is adapted to the length of the sample rack of the sample tube assembly. Simultaneously, a unloading limit stop is provided on the side of the unloading platform 104 to prevent the sample rack from moving in the direction perpendicular to the unloading platform 104. In this embodiment, a second trigger switch 1072 is provided on the first conveying track 101, such as... Figure 14 As shown, when the sample tube group after sampling touches the second trigger switch 1072, the first conveying track 101 stops sample conveying, and the second pushing block 601 pushes the sample tube group on the first conveying track 101 onto the unloading platform 104. The first trigger switch 1071 and the second trigger switch 1072 are both existing technologies, equivalent to position detection devices, and will not be described in detail here.
[0052] The expedited processing component 300 is located on the other side of the first conveyor track 101 and corresponds to the position of the loading platform 103. The expedited processing component 300 is equipped with a reciprocating expedited pusher 308, such as... Figure 2 and Figure 7 As shown, when emergency sampling and testing are required, the expedited pusher 308 will push the sample tube group that is currently located on the first conveying track 101 but has not yet entered the sampling procedure back to the loading platform 103, thereby leaving a preset space on the first conveying track 101, so that the operator can place the expedited sample tube group on the first conveying guide rail 101 to enter the next sampling and testing process.
[0053] This application provides an expedited processing component 300 on the opposite side of the loading platform 103 of the first conveying track 101. The expedited processing component 300 is equipped with an expedited pusher 308 that moves back and forth. By moving the expedited pusher 308, space is reserved on the first conveying track 101 for expedited sample tube groups. This enables expedited sample processing on the same testing instrument without the need for an additional separate expedited sample testing instrument, reducing the equipment cost of the testing institution. At the same time, it does not disrupt the original testing sequence of the current instrument, ensuring the testing of normal sample tube groups and guaranteeing testing efficiency.
[0054] In this embodiment, refer again Figure 7 The expedited processing component 300 also includes a first drive motor 301 and a first rotating shaft 305. The first drive motor 301 is mounted on the base 100, and the first rotating shaft 305 is connected to the output shaft of the first drive motor 301. One end of the expedited push block 308 is mounted on the first rotating shaft 305. The first drive motor 301 drives the first rotating shaft 305 to rotate, thereby causing the expedited push block 308 to rotate towards the material feeding platform 103, thus pushing the sample tube group away from the first conveying track 101. In this embodiment, to reduce the swing space of the expedited push block 308, two shorter rocker arms are used instead of the expedited push block 308. At the same time, two first rotating shafts 305 are used for synchronous driving and share one first drive motor 301 for driving.
[0055] Specifically, a first rotating pulley 302 is provided on the output shaft of the first drive motor 301, two second rotating pulleys 304 are provided on one of the first rotating shafts 305, and a third rotating pulley 307 is provided on the other first rotating shaft 305. The first rotating pulley 302 is connected to one of the second rotating pulleys 304 by a first rotating synchronous belt 303, and the third rotating pulley 307 is connected to the other second rotating pulley 304 by a third synchronous belt 306. By providing the first rotating pulley 302, two second rotating pulleys 304 and one third rotating pulley 307, the synchronous rotation of the two first rotating shafts 305 is achieved, reducing the number of drive devices and also reducing the swing space required for the expedited push block 308.
[0056] Alternatively, the two first rotating shafts 305 can be driven separately, ensuring that the two first rotating shafts 305 swing synchronously.
[0057] Optionally, the expedited push block 308 can also be configured as a translational drive structure. For example, the movement path of the expedited push block 308 is a straight line, perpendicular to the conveying route of the first conveying track 101, that is, it is driven by a linear cylinder, or a guide rail slider structure combined with a screw nut structure to achieve linear movement, or a guide sleeve guide shaft structure to replace the aforementioned guide rail slider structure.
[0058] In one embodiment, Figure 2 and Figure 4 As shown, the first conveying track 101 includes a first base plate 1015, a first side plate 1016, a first synchronous belt 1013, a first driving pulley 1012, a first driven pulley 1014, and a first conveying motor 1011. The first base plate 1015 is disposed on the first mounting platform of the base 100. The first side plate 1016 is connected to the first base plate 1015 and is perpendicular to each other. The first side plate 1015 is provided with a first limiting stop 10161. The first limiting stop 10161 limits the sample rack to prevent the sample rack from moving in the direction perpendicular to the first base plate 1015.
[0059] Furthermore, the first driving pulley 1012 and the first driven pulley 1014 are rotatably disposed at both ends of the first base plate 1015 (i.e., along the length of the first base plate 1015), and the first synchronous belt 1013 is wound around the first driving pulley 1012 and the first driven pulley 1014, with a portion of the first synchronous belt 1013 abutting against the top of the first base plate 1015, so that the first base plate 1015 supports the first synchronous belt 1013. The sample tube assembly is placed on the first synchronous belt 1013. In this embodiment, the width of the first synchronous belt 1013 is adapted to the width of the first base plate 1015. Edge strips 10151 are provided on both sides of the first base plate 1015 to form grooves, and the first synchronous belt 1013 is located within these grooves. The first conveyor motor 1011 is mounted on the base 100 via a bracket. The first drive pulley 1012 is fixedly connected to the output shaft of the first conveyor motor 1011. The rotation of the first conveyor motor 1011 drives the first synchronous belt 1013 to rotate, thereby realizing the transfer and transportation of the sample tube assembly. It should be noted that in this embodiment, the first conveyor motor 1011 can achieve forward and reverse rotation, thereby returning sample tube assemblies that have been transported but have not yet undergone sample information scanning to the loading platform 103.
[0060] In one embodiment, the multifunctional sample detection and transfer track further includes a first rotating component 400, which is used to rotate the sample tubes. Since sample information is affixed to the sample tubes, the orientation of the affixed information may be inconsistent when the operator places the sample tubes on the sample rack. Therefore, the sample tubes need to be rotated to ensure the information is aligned for easy scanning and subsequent steps. In this embodiment, the sample information can be a QR code or a barcode.
[0061] Specifically, if Figure 8 and Figure 9As shown, the first rotating assembly 400 includes a first rotating bracket 401 fixedly mounted on the base 100, a first rotating motor 403 mounted on the first rotating bracket 401, and a first main rotating disk 404 mounted on the output shaft of the first rotating motor 403. The first rotating motor 403 rotates to drive the first main rotating disk 404 to rotate.
[0062] The first rotating assembly 400 also includes a second rotating bracket 508, on which two first auxiliary rotating disks 405 are disposed. The second rotating bracket 508 is movably disposed on the base 100. For example, the second rotating bracket 508 can move closer to or away from the first conveying track 101. The second rotating bracket 508 and the first rotating bracket 401 are disposed on both sides of the first conveying track 101. By moving the second rotating bracket 508 closer to or away from the first conveying track 101, the two second auxiliary rotating disks 405 and the first main rotating disk 404 can be used to abut and fix the sample tube. The rotation of the first main rotating disk 404 drives the sample tube to rotate to the information scanning position.
[0063] Furthermore, in order to reduce the resistance encountered during the rotation of the sample tube, two second auxiliary rotating disks 405 are rotatably mounted on the second rotating support 508.
[0064] Furthermore, to avoid excessive pressure from the second auxiliary rotating disk 405 and the first main rotating disk 404 on the sample tube, the two second auxiliary rotating disks 405 are elastically mounted on the second rotating support 508. Specifically, two horizontal and parallel second fixing posts 408 are provided on the second rotating support 508, with one end of each post fixed to the support. Second mounting supports 406, movable axially along the posts 408, are provided on each post. The two second auxiliary rotating disks 405 are rotatably mounted on the second mounting supports 406. Two second buffer springs 407 are also fitted on the posts 408. When the two second auxiliary rotating disks 405 contact the sample tube, the second buffer springs 407 are compressed, so that the pressure on the sample tube is only the spring force. This avoids direct rigid contact between the second auxiliary rotating disks 405 and the first main rotating disk 404, which could damage the sample tube or cause excessive resistance during rotation.
[0065] In one embodiment, a scanner 402 is also fixed on the first rotating support 401. The scanner 402 is used to scan sample information on the sample tube. When the sample information on the sample tube is not in the scanning position, the first main rotating disk 404 rotates, driving the sample tube to the scanning position, thereby enabling the scanner 402 to complete the scanning of the sample information. In this embodiment, the scanner 402 is prior art and will not be described in detail.
[0066] In one embodiment, the multifunctional sample detection and transfer track further includes a sampling fixing component 500 that moves relative to the base 100. The sampling positioning component 500 includes a sampling limiter 5083 and a sampling baffle 509, wherein the sampling baffle 509 and the sampling limiter 5083 are arranged on the same track, and the sampling limiter 5083 is disposed on the second rotating bracket 508. The sampling limiter 5083 and the sampling baffle 509 can move synchronously towards each other or away from each other. By setting a sampling baffle 509, the movement of the sampling baffle 509 can position the sampling tubes on the sample tube group and place them on the same straight line. Combined with the sampling limiter 5083, it can fix one of the sampling tubes in the sample tube group, so that the rubber stopper of the sample tube is located below the sampling positioner 5083. The sampling needle passes through the sampling positioner 5083 and penetrates into the sample tube to take a sample. When the sampling needle withdraws from the sample tube, the sampling positioner 5083 limits the rubber stopper in the sample tube axis direction to prevent the sampling needle from pulling the rubber stopper out of the sample tube. In this embodiment, the sampling limiter 5083 is provided with a U-shaped fixing groove, the size of which is adapted to the outer diameter of the sampling tube.
[0067] Furthermore, to avoid rigid contact between the sampling limiter 5083 and the sample tube during sampling, the sampling limiter 5083 is movably mounted on the second rotating bracket 508. Specifically, a first linear guide rail 5081 is provided on the second rotating bracket 508, a first slider 5082 is provided on the first linear guide rail 5081, the sampling limiter 5083 is mounted on the first slider 5082, and a tension spring (not shown in the figure) is provided on the second rotating bracket 508. One end of the tension spring is fixedly connected to the second rotating bracket 508, and the other end is fixedly connected to the sampling limiter 5083. When the sampling limiter 5083 engages and positions the sample tube, the force applied by the sampling limiter 5083 to the sample tube is only the elastic force of the tension spring, achieving an elastic connection between the sampling limiter 5083 and the second rotating bracket 508. Furthermore, a first buffer spring 5102 is provided between the second connecting block and the sampling bracket. One end of the first buffer spring 5102 abuts against the second connecting block 5101, and the other end is fixedly connected to the sampling bracket 501. When the sampling baffle 509 moves toward the sampling limiter 5083, the second buffer spring 5102 is compressed, which further ensures the elastic contact of the sampling baffle 509 with the sample tube.
[0068] Specifically, if Figures 9-11 As shown, a sampling bracket 501 is provided on the base 100, a first sampling guide rail 506 is provided on the sampling bracket 501, a first sampling slider 507 and a second sampling slider 510 are provided on the first sampling guide rail 506, a second rotating bracket 508 is provided on the first sampling slider 507, and a sampling baffle 509 is provided on the second sampling slider 510.
[0069] Furthermore, a first sampling motor 502 is provided on the sampling bracket 501, a first sampling drive wheel 503 is provided on the output shaft of the first sampling motor 502, a rotatable first sampling driven wheel 505 is provided on the sampling bracket 501, and a first sampling synchronous belt 504 is sleeved on the first sampling driven wheel 505 and the first sampling drive wheel 503. The first sampling synchronous belt 504 is arranged parallel to the first sampling guide rail 506. The first sampling slider 507 is connected to the first sampling synchronous belt 504 located below the first sampling drive wheel 503, and the second sampling slider 510 is connected to the first sampling synchronous belt 504 located above the first sampling drive wheel 503. In this embodiment, the first sampling slider 507 is connected to the first sampling synchronous belt 504 through a first connecting block 5071, and the second sampling slider 510 is connected to the first sampling synchronous belt 504 through a second connecting block 5101. By rotating the first sampling motor 502 in both directions, the first sampling slider 507 and the second sampling slider 510 are driven to move towards or away from each other, thereby realizing the opening and closing of the sampling baffle 509 and the sampling limiter 5083.
[0070] In one embodiment, Figure 13 and Figure 15 As shown, it also includes a second translation component 600, which is used to drive the reciprocating movement of the second push block 601. Specifically, the second translation component 600 includes a second translation guide rail 606, a second translation slider 607, a second translation motor 602, a second translation drive pulley 603, a second translation driven pulley 605, and a second translation synchronous belt 604. The second translation guide rail 606 is disposed on the base 100, the second translation slider 607 is disposed on the second translation guide rail 606, the second translation motor 602 is disposed on the base 100, the second translation drive pulley 603 is disposed on the output shaft of the second translation motor 602, the second translation driven pulley 605 is rotatably disposed on the base 100, and the second translation synchronous belt 604 is wound around the second translation drive pulley 603 and the second translation driven pulley 605. The second push block 601 is connected to the second translation slider 607, and the second translation slider 607 is connected to the second translation synchronous belt 604. In this embodiment, the second push block 601 is driven to reciprocate linearly by the forward and reverse rotation of the second translation motor 602.
[0071] Optionally, the transmission structure of the second translational driving pulley 603, the second translational driven pulley 605, and the second translational synchronous belt 604 can be replaced by a linear cylinder or a lead screw and nut structure.
[0072] In one embodiment, a third translation component 106 is also included. The third translation component 106 is provided with a third push block 1061. The third push block 1061 is used to push the sample tube group from the unloading platform 104 near one end of the first conveying track 101 to the unloading platform 104 far away from the first conveying track 101, so as to facilitate the unloading platform 104 to store or transfer the sample tube group after sampling.
[0073] Specifically, if Figure 5 and Figure 6 As shown, the third translation component 106 includes a third translation motor 1060 mounted on a base, a third translation drive wheel 1062 mounted on the output end of the third translation motor 1060, a third translation driven wheel 1064 rotatably mounted on the base 100, a third translation timing belt 1063 wound around the third translation drive wheel 1062 and the third translation driven wheel 1064, a third translation guide rail 1065 mounted on the base 100, and a third translation slider 1066 mounted on the third translation guide rail 1065. A third push block 1061 is mounted on the third translation slider 1066.
[0074] Furthermore, the third pushing block 1061 includes a third pushing bracket 10612, which is mounted on the third translation slider 1066. The third pushing bracket 10612 has two branches extending to both sides of the unloading platform 104. Elastic pushing blocks 10611 are mounted on the two branches, rotatably mounted on the branches, and can only rotate away from the first conveying track 101. This allows the second pushing block 602 to push the sample tube assembly from the first conveying track 101 onto the unloading platform 104 via the elastic pushing blocks 10611, without requiring the elastic pushing blocks 10611 to make way, simplifying the structure of this part. Specifically, the elastic pushing block 10611 is rotatably mounted on the branch, and a torsion spring and a first limiting post 106121 are mounted on the branch. The first limiting post 106121 limits the rotation of the elastic pushing block 10611, and the torsion spring is used for the reset of the elastic pushing block 10611. When the elastic push block 10611 rotates, the torsion spring rotates accordingly, allowing the sample tube assembly to move between the two elastic push blocks 10611 and onto the feeding platform 104. After the sample tube assembly passes between the two elastic push blocks 10611, the elastic push block 10611 resets under the action of the torsion spring and abuts against the first limiting post 106121. Furthermore, a first guide slope 106111 is provided on the elastic push block 10611 to facilitate the sample tube assembly's disengagement from the elastic push block 10611. It should be noted that the structure and transmission structure and principle of the first push block are the same as those of the third push block and the third translation component, and will not be elaborated further here.
[0075] In one embodiment, to facilitate automated online testing with adjacent testing instruments, a second conveying track 102 is also included. The second conveying track 102 is disposed on the base 100 and is parallel to the first conveying track 101. The length of the second conveying track 102 matches the length of the first conveying track 101. The loading platform 103 and the unloading platform 104 are both disposed between the first conveying track 101 and the second conveying track 102. The second conveying track 102 is connected to the loading platform 103 and the unloading platform 104. The conveying direction of the second conveying track 102 is consistent with the conveying direction of the first conveying track 101.
[0076] Specifically, the second conveying track 102 includes a second base plate and a second side plate. The second base plate is mounted on the base, and the second side plate is connected to the second base plate and perpendicular to each other. A human limiting stop is provided on the second side plate to limit the sample rack of the sample tube assembly, preventing the sample rack from moving vertically. The second conveying track also includes a driving device, specifically a second conveying motor, a second driving pulley, a second driven pulley, and a second synchronous belt. The second conveying motor is mounted on the base, the second driving pulley is located at one end of the second base plate and connected to the output shaft of the second conveying motor, the second driven pulley is rotatably mounted at the other end of the second base plate, and the second synchronous belt is wound around the second driving pulley and the second driven pulley, and is attached to the second base plate. The sample tube assembly is located on the second synchronous belt, and the second base plate supports the second synchronous belt. It should be noted that the principle of the second conveying track is the same as that of the first conveying track, both using a synchronous pulley and synchronous belt structure for transmission.
[0077] In one embodiment, to facilitate the pushing of the sample tube assembly on the second conveying track 102 onto the loading platform 103, a fourth translation component 200 is provided on the base 100. The fourth translation component 200 is provided with a fourth pushing block 201, which can reciprocate linearly between the loading platform 103 and the second conveying track 102. In this embodiment, the fourth translation component 200 and the second translation component 600 have the same structure and principle, as described above, and will not be repeated here.
[0078] Furthermore, such as Figure 13 As shown, when it is not necessary for two adjacent testing instruments to be connected, a first limiting component 800 is set on the second conveying track 102 near the unloading platform 104. The first limiting component 800 is provided with a first limiting baffle 804. Part of the first limiting baffle 804 can be moved onto the second conveying track 102, thereby preventing the sample tube group from flowing onto the second conveying track 102 of the next testing instrument.
[0079] Further, the first limiting component 800 includes a first driving member 801, a first transmission member, a first limiting guide rail 806, and a first limiting slider 805. The first driving member 801 is connected to the first limiting slider 805 through the first transmission member. The first limiting guide rail 806 is disposed on the base 100, the first limiting slider 805 is disposed on the first limiting guide rail 806, and the first limiting baffle 804 is disposed on the first limiting slider 805. In this embodiment, the first driving member 801 is a motor, and the first transmission member includes a first rocker arm 802 and a first connecting rod 803. One end of the first rocker arm 802 is fixed to the output shaft of the first driving member 801, and both ends of the first connecting rod 803 are hinged to the first limiting baffle 804 and the free end of the first rocker arm 802, respectively. The rotation of the motor drives the first rocker arm 802 to rotate and the first connecting rod 803 to swing, thereby driving the first limiting baffle 804 to reciprocate and extend. Optionally, the first driving component 801 can also be connected to the free end of the linear cylinder via the first limit slider 805, thereby enabling the reciprocating linear movement of the first limit baffle 804. Optionally, the first transmission component can also be a lead screw and nut structure, which, in combination with the lead screw and nut, enables the reciprocating linear movement of the first limit baffle 804 via the forward and reverse rotation of the motor.
[0080] In one embodiment, Figure 16 As shown, the multifunctional sample testing and transfer track can also be applied to different testing instruments, enabling online processing between different testing instruments. Two adjacent different testing instruments are connected through the second conveyor track 102. According to different testing requirements, different sample tube groups are pushed to the loading platform 103 of the corresponding testing instrument. After the current item testing is completed, it can be pushed to the second conveyor track 102 through the unloading platform 104 to the loading platform 103 of the next testing instrument for testing. Different data testing of the same sample tube group can be realized; it can also realize single item testing of multiple sample tube groups. That is, when a sample tube group needs to be tested for a single item, it is transported to the loading platform 103 of the corresponding testing instrument through the second conveyor track 102. After the test is completed, it is pushed to the second conveyor track 102 through the unloading platform 104, thus completing the single item testing.
[0081] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model. These improvements and modifications should also be considered within the scope of protection of this utility model.
