Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and more specifically, to a single-tube delivery line for an analyzer. Background Technology

[0002] With the continuous development of medical technology, hospitals have increasingly higher requirements for the efficiency and accuracy of sample processing. Traditional sample processing methods usually rely on manual operation, which is not only time-consuming and labor-intensive but also prone to human error. In order to improve work efficiency and reduce labor costs, hospitals urgently need a device that can intelligently and automatically process samples.

[0003] Currently, some hospitals have begun using automated equipment to process samples in test tubes. This equipment can classify and transport samples collected in test tubes, improving work efficiency to some extent. However, existing automated equipment still has some problems. First, the equipment lacks sufficient intelligence and cannot flexibly adjust to the characteristics of different samples. Second, the equipment's transport efficiency is limited, failing to meet the sample processing needs of large hospitals during peak periods. Furthermore, the reliability and stability of existing equipment need improvement, frequently experiencing problems such as tube jamming and sample leakage, affecting overall work efficiency.

[0004] On the other hand, existing automated equipment is often bulky and takes up a lot of space, making it unsuitable for use in hospital laboratories with limited space. Furthermore, the operation of this equipment is complex, requiring professional personnel for maintenance and debugging, which increases the hospital's operating costs.

[0005] Therefore, there is an urgent need for a highly intelligent, efficient, reliable, compact, and easy-to-operate single-tube analyzer delivery line to meet the sample processing needs of modern hospitals, improve work efficiency, reduce labor costs, and ultimately enhance the quality of medical services. Utility Model Content

[0006] The purpose of this application is to provide a single-tube conveyor line for an analyzer, which has the advantages of high intelligence, high conveying efficiency, good reliability and easy operation.

[0007] This application provides a single-tube delivery line for an analyzer, including a main body of the delivery line. The main body is equipped with an inlet track, an outlet track, and a suction track for transporting samples. The front end of the inlet track is equipped with a positioning optocoupler for detecting sample arrival. The rear end of the inlet track is connected to the front end of the outlet track. A transfer component is provided between the inlet and outlet tracks to transfer the sample from the inlet track to the outlet track. The front end of the suction track is equipped with a transfer-in component to transfer the sample from the outlet track to the suction track. The rear end of the suction track is equipped with a transfer-out component to transfer the sample from the suction track to the outlet track. A single-tube positioning device for positioning the sample is provided on the suction track. An identification sensor is provided on the main body of the delivery line, and the identification sensor is signal-connected to the transfer-in component.

[0008] Compared with existing technologies, the single-tube transport line of this analyzer has the following advantages: Through a multi-track layout, the system can simultaneously process multiple samples in different states, improving overall processing efficiency. The arrangement of transfer, input, and output components allows for flexible sample transfer between different tracks, adapting to various processing needs. Simultaneously, the application of a single-tube positioning device ensures precise sample positioning during the aspiration stage, improving the accuracy of subsequent operations. The introduction of identification sensors enables the system to intelligently identify sample information, providing a foundation for automated processing. This achieves automated sample transport and processing.

[0009] In one possible implementation, the transfer component includes a sample guide plate, a guide plate shaft, a transmission assembly, a fixed base, and a first drive motor. The sample guide plate is rotatably positioned between the sample inlet track and the sample outlet track. The sample guide plate is fixed to the guide plate shaft, which is rotatably connected to the main body of the conveyor line. The first drive motor is mounted below the conveyor line via the fixed base and drives the guide plate shaft to rotate via the transmission assembly. Compared with the prior art, the sample guide plate structure enables smooth transfer of the sample from the sample inlet track to the sample outlet track. The sample guide plate is rotatably connected to the main body of the conveyor line via the guide plate shaft, and the first drive motor drives the guide plate shaft to rotate via the transmission assembly, thereby rotating the sample guide plate. This structural design allows the sample to be stably transferred from the sample inlet track to the sample outlet track, preventing the sample from tipping over or being damaged during the transfer process.

[0010] In one possible implementation, the sample guide plate is provided with a slot for the sample to be fitted and engaged. Compared with the prior art, the slot for the sample to be fitted and engaged achieves a stable connection between the sample and the sample guide plate, improving the fixing effect of the sample guide plate on the sample.

[0011] In one possible implementation, the transmission assembly is any one of a timing belt assembly, a gear assembly, or a sprocket assembly. Compared to the prior art, this provides a variety of possibilities for the selection of the transmission assembly, increasing the system's flexibility and adaptability.

[0012] In one possible implementation, the transfer component includes a variable-track swing arm, a swing arm shaft, a mounting base, and a second drive motor. The variable-track swing arm is rotatably connected to the front end of the sample suction track via the swing arm shaft. The second drive motor is fixed below the main body of the conveyor line via the mounting base, and the output shaft of the second drive motor is connected to the swing arm shaft. Compared with the prior art, the motor-driven variable-track swing arm not only achieves automated operation but also ensures the smoothness and accuracy of the transfer process through precise angle control. Furthermore, the design of this application is compact, occupies little space, and is easily integrated into existing analyzer systems, improving the overall space utilization of the equipment.

[0013] In one possible implementation, the transfer component further includes a guide groove located at the front end of the sample suction track, the guide groove communicating with the sample discharge track, and the track-changing swing arm located within the guide groove. Compared with the prior art, the above technical solution better guides the sample from the sample discharge track into the sample suction track, improving the smoothness and reliability of the transfer process. It improves the transfer efficiency and reliability of the sample from the sample discharge track to the sample suction track.

[0014] In one possible implementation, the transfer component includes a discharge slot located at the rear end of the sample suction track, which communicates with the sample discharge track. Compared to existing technologies, by setting a discharge slot at the rear end of the sample suction track, the connection between the sample suction track and the sample discharge track is achieved, providing a simple and efficient channel for sample transfer. The design of the discharge slot also considers the smoothness and reliability of sample transfer. Through reasonable structural design and parameter selection, it ensures that the sample can be safely and quickly transferred from the sample suction track to the sample discharge track, improving the overall efficiency of the single-tube delivery line of the analyzer.

[0015] In one possible implementation, the single-tube positioning device includes a support frame, an active clamping arm, a driven clamping arm, and a drive mechanism. The support frame is fixedly installed on the main body of the conveyor line and located above the sample suction track. The active clamping arm is hinged to the support frame via a first hinge shaft, and the driven clamping arm is hinged to the support frame via a second hinge shaft. A first torsion spring is sleeved on the first hinge shaft, which drives the active clamping arm to rotate toward the driven clamping arm. A second torsion spring is sleeved on the second hinge shaft, which drives the driven clamping arm to rotate toward the active clamping arm, so that the active and driven clamping arms together clamp the test tube. The active clamping arm is provided with two first clamping wheels for adhering to the test tube wall, and the driven clamping arm is provided with two second clamping wheels for adhering to the test tube wall. The drive mechanism is installed on the support frame and drives the active and driven clamping arms to open away from each other. Compared with existing technologies, the single-tube positioning device effectively solves the problem of inaccurate test tube positioning through its unique structural design and automated control. It not only improves the efficiency and reliability of the entire single-tube delivery line of the analyzer, but also provides a more stable and accurate foundation for subsequent sample processing.

[0016] In one possible implementation, the drive mechanism includes a main drive arm, a driven arm, a drive cam, and a third drive motor. The third drive motor is mounted on a support frame, and its output shaft is connected to the drive cam. The front end of the main drive arm is hinged to a first hinge shaft and fixed to the active clamping arm. The rear end of the main drive arm is connected to the drive cam to drive the active clamping arm to open. The front end of the driven arm is hinged to a second hinge shaft and fixed to the driven clamping arm. The rear end of the driven arm is connected to the main drive arm to drive the driven clamping arm to open. Compared with the prior art, precise control of the active and driven clamping arms is achieved by using a combination of the drive cam, the main drive arm, and the driven arm. The drive cam is driven by the third drive motor, enabling precise angle control. The main drive arm is directly connected to the drive cam, thereby converting the rotational motion of the cam into the opening and closing motion of the active clamping arm. The driven arm, through its connection with the main drive arm, achieves synchronous opening and closing of the driven clamping arm.

[0017] In one possible implementation, at least one positioning fork device is also installed on the main body of the conveyor line. The positioning fork device includes a fourth drive motor, a mounting base, a fork component, a gear, and a rack. The fourth drive motor is fixed below the main body of the conveyor line via the mounting base. The output shaft of the fourth drive motor is connected to the gear. Two racks are provided, each meshing with one side of the gear. The two racks slide vertically on the main body of the conveyor line, and each rack has one of the fork components. Compared with the prior art, by adopting the above technical solution, the positioning fork device, along with other components of this application, such as the transfer component, the input component, and the output component, forms a coordinated whole. By precisely controlling the position and movement of the sample on each track, the working efficiency and reliability of the entire conveyor line are greatly improved. Attached Figure Description

[0030] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0031] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0032] In the embodiments of this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0033] In the field of medical testing equipment, the application of automated analyzers has greatly improved sample processing efficiency. However, existing analyzer delivery systems still face some technical challenges when processing single-tube samples. The main issues lie in the intelligent delivery and precise positioning of single-tube samples. These problems directly affect the analyzer's processing speed, accuracy, and overall efficiency.

[0034] Specifically, in the laboratories of large medical institutions, tens of thousands of single-tube samples are processed daily. Traditional delivery systems often employ fixed-track designs, lacking flexibility. For example, when prioritizing or repeating certain samples requires faster response, the system cannot keep up. Furthermore, precise sample positioning during delivery is a critical issue. Deviations in sample position can lead to aspiration errors or sample identification failures, thus affecting the accuracy of test results.

[0035] Therefore, these technical issues have a significant impact on the entire testing process. First, the efficiency of single-tube sample delivery directly determines the overall processing capacity of the analyzer. The inability to achieve intelligent delivery will lead to sample backlog and prolonged testing cycles. Second, inaccurate sample positioning can trigger a series of chain reactions, including inaccurate sample volume and incorrect sample information reading. This not only affects the test results of individual samples but may also cast doubt on the reliability of data from the entire batch. Finally, if the system cannot flexibly handle urgent samples or repeated testing needs, it will severely impact the diagnostic efficiency of medical institutions and the quality of patient services.

[0036] If these technical problems are not effectively resolved, they will have a profound negative impact on the field of medical testing. Therefore, developing a single-tube sample delivery system capable of intelligent delivery, precise positioning, and flexible processing is of great significance for improving the overall level of medical testing. This is not only related to the operational efficiency of individual medical institutions, but also to the quality improvement of the entire healthcare service system.

[0037] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0038] See Figures 1 to 10This application discloses a single-tube transport line for an analyzer, including a transport line body 1. The transport line body 1 is equipped with an inlet track 2, an outlet track 3, and an aspiration track 4 for transporting samples. The front end of the inlet track 2 is provided with a positioning optocoupler 5 for detecting sample arrival. The rear end of the inlet track 2 is interconnected with the front end of the outlet track 3. A transfer component 6 is provided between the inlet track 2 and the outlet track 3 for transferring the sample from the inlet track 2 to the outlet track 3. The front end of the aspiration track 4 is provided with a transfer-in component 7 for transferring the sample from the outlet track 3 to the aspiration track 4. The rear end of the aspiration track 4 is provided with a transfer-out component 8 for transferring the sample from the aspiration track 4 to the outlet track 3. A single-tube positioning device 9 for positioning the sample is provided on the aspiration track 4. An identification sensor 10 is provided on the transport line body 1, and the identification sensor 10 is signal-connected to the transfer-in component 7.

[0039] Specifically, the conveyor body 1 refers to the basic structure of the entire conveyor system; the sample inlet track 2 refers to the channel used to receive the initial sample; the sample outlet track 3 refers to the channel used to output the processed sample; the sample suction track 4 refers to the channel specifically used for the sample detection process; the sample inlet track 2, the sample outlet track 3, and the sample suction track 4 are all belt conveyor structures; the positioning optocoupler 5 refers to the sensor used to detect whether the sample has reached the designated position, which can be implemented using an infrared through-beam photoelectric switch; the identification sensor 10 refers to the device used to identify sample information, which can be implemented using a barcode scanner or an RFID reader.

[0040] As described above, the multi-track design, equipped with an intelligent transfer and positioning mechanism, enables intelligent transport and precise positioning of single-tube samples. Through the rational layout of the sample inlet track 2, sample outlet track 3, and sample suction track 4, combined with the coordinated operation of the transfer component 6, transfer-in component 7, and transfer-out component 8, this application can flexibly handle samples in different states. Simultaneously, the placement of the optical coupler 5 and the single-tube positioning device 9 ensures accurate sample positioning at each stage, while the application of the identification sensor 10 further enhances the system's intelligence level. The analyzer single-tube transport line of this application enables intelligent transport and precise positioning of single-tube samples, improving the analyzer's processing efficiency and accuracy.

[0041] See also Figure 3In this embodiment, the transfer component 6 includes a sample guide plate 61, a guide plate shaft 62, a transmission assembly 63, a fixed base 64, and a first drive motor 65. The sample guide plate 61 is rotatably disposed between the sample inlet track 2 and the sample outlet track 3. The sample guide plate 61 is fixed to the guide plate shaft 62, which is rotatably connected to the main body 1 of the conveyor line. The first drive motor 65 is mounted below the conveyor line via the fixed base 64 and drives the guide plate shaft 62 to rotate via the transmission assembly 63. Specifically, the sample guide plate 61, disposed between the sample inlet track 2 and the sample outlet track 3, serves as a transfer station, receiving samples from the sample inlet track 2 and transferring them to the sample outlet track 3. The fixed connection between the sample guide plate 61 and the guide plate shaft 62 ensures synchronous rotation. The guide plate shaft 62, rotatably connected to the main body 1 of the conveyor line, provides stable support and a rotation axis for the sample guide plate 61. The first drive motor 65 is mounted below the conveyor line via a mounting bracket 64. This mounting method not only saves space but also lowers the center of gravity, improving the stability of the entire device. The first drive motor 65 is connected to the guide plate shaft 62 via a transmission assembly 63, which can precisely transmit the motor's power to the guide plate shaft 62, enabling precise control of the sample guide plate 61.

[0042] In this embodiment, the sample guide plate 61 is provided with a slot 611 for the sample to be fitted and inserted. Specifically, the slot 611 can be designed as a groove structure that matches the shape of the bottom of the sample. When the sample is placed on the sample guide plate 61, the bottom of the sample can be precisely embedded in the slot 611. This design not only prevents the sample from sliding or tipping over during transfer, but also ensures that the sample's position on the guide plate remains fixed and accurate. The depth of the slot 611 can be adjusted according to the height of the sample to ensure that the sample does not protrude excessively or sink excessively after being inserted. The edge of the slot 611 can be designed as slightly inclined or rounded to facilitate the smooth entry and exit of the sample.

[0043] In this embodiment, the transmission component 63 is a synchronous belt assembly. Specifically, the synchronous belt assembly typically consists of a synchronous belt and a synchronous pulley. The synchronous belt has evenly distributed teeth that can precisely mesh with the tooth grooves on the synchronous pulley, ensuring that slippage does not occur during transmission. The synchronous belt assembly features smooth transmission, low noise, and high efficiency, making it suitable for applications requiring precise positioning. The transmission component 63 can also be a gear 204 assembly or a sprocket assembly. This flexible selection of the transmission component 63 allows the single-tube conveyor line of the analyzer in this application to adapt to different working environments and requirements. By selecting a suitable transmission component 63, the transmission efficiency of the system can be optimized, the stability and reliability of operation can be improved, and subsequent maintenance and upgrades can be facilitated.

[0044] See also Figure 4In this embodiment, the transfer component 7 includes a variable-track swing arm 71, a swing arm shaft 72, a mounting base 73, and a second drive motor 74. The variable-track swing arm 71 is rotatably connected to the front end of the sample suction track 4 via the swing arm shaft 72. The second drive motor 74 is fixed below the main body 1 of the conveyor line via the mounting base 73, and the output shaft of the second drive motor 74 is connected to the swing arm shaft 72. The variable-track swing arm 71 is rotatably connected to the front end of the sample suction track 4 via the swing arm shaft 72, allowing it to rotate around the swing arm shaft 72. The second drive motor 74 is fixed below the main body 1 of the conveyor line via the mounting base 73, ensuring the stability of the second drive motor 74 without interfering with the movement of other components. The output shaft of the second drive motor 74 is connected to the swing arm shaft 72, allowing the motor's rotational motion to be directly transmitted to the variable-track swing arm 71. The variable-track swing arm 71 can adopt various shapes to facilitate pushing the sample from the sample dispensing track 3 into the sample suction track 4. The swing arm shaft 72 can be supported by bearings to reduce friction and improve the smoothness of movement. The mounting base 73 can be made of metal to improve stability and durability. The second drive motor 74 can be a stepper motor or a servo motor to achieve precise angle control. In practical applications, when the sample needs to be transferred from the sample dispensing track 3 to the sample suction track 4, the identification sensor 10 detects and identifies the sample and sends a signal to the transfer component 7. After receiving the signal, the second drive motor 74 starts and drives the swing arm shaft 72 to rotate through its output shaft. The rotation of the swing arm shaft 72 drives the variable-track swing arm 71 to rotate, pushing the sample from the sample dispensing track 3 into the sample suction track 4. After the transfer is completed, the second drive motor 74 rotates in the opposite direction, causing the variable-track swing arm 71 to return to its initial position, waiting for the next transfer operation. This design has the following advantages: First, the automatic transfer of the sample is achieved through motor drive, improving the efficiency and accuracy of the operation. Secondly, the design of the variable-track swing arm 71 makes the transfer process smoother and reduces the impact that the sample may be subjected to. Thirdly, the design of the mounting base 73 ensures the stability of the entire transfer component 7, improving its long-term reliability. Finally, this design scheme has a simple structure and is easy to maintain and adjust.

[0045] In this embodiment, the transfer component 7 also includes an inlet groove 75 located at the front end of the sample suction track 4. The inlet groove 75 communicates with the sample discharge track 3, and the variable-track swing arm 71 is located within the inlet groove 75. Specifically, the inlet groove 75 is located at the front end of the sample suction track 4 and communicates with the sample discharge track 3. This communication design can form a smooth transition area, reducing the obstacles that the sample may encounter during the transfer process. The variable-track swing arm 71 is located within the inlet groove 75, which can more precisely control the movement path of the sample under the guidance of the inlet groove 75. The presence of the inlet groove 75 can prevent the sample from deviating from the predetermined path during the transfer process. In practical applications, when the identification sensor 10 detects that the sample needs to be suctioned, it sends a signal to the transfer component 7. After receiving the signal, the second drive motor 74 drives the swing arm shaft 72 to rotate, causing the variable-track swing arm 71 to swing. The variable-track swing arm 71 pushes the sample on the sample discharge track 3 into the inlet groove 75, and the sample smoothly enters the sample suction track 4 under the guidance of the inlet groove 75. Throughout the process, the presence of the inlet groove 75 ensures the stability and predictability of the sample movement path.

[0046] See also Figure 2 In this embodiment, the transfer component 8 includes a transfer groove 81 located at the rear end of the suction track 4, which communicates with the discharge track 3. The transfer groove 81 connects the suction track 4 and the discharge track 3, providing a channel for the sample to move from the suction track 4 to the discharge track 3. In practical applications, after the sample has been suctioned on the suction track 4, a command can be issued by the control system to release the clamp on the test tube by the single-tube positioning device 9. At this time, the test tube will slide along the transfer groove 81 onto the discharge track 3 under the transport action of the suction track 4. The transfer groove 81 simplifies the sample transfer process from the suction track 4 to the discharge track 3, eliminating the need for additional mechanical structures, improving transfer efficiency, and reducing system complexity.

[0047] See also Figures 5 to 9In this embodiment, the single-tube positioning device 9 includes a support frame 91, an active clamping arm 92, a driven clamping arm 93, and a drive mechanism 94. The support frame 91 is fixedly installed on the main body 1 of the conveyor line and located above the sample suction track 4. The active clamping arm 92 is hinged to the support frame 91 via a first hinge pin 95, and the driven clamping arm 93 is hinged to the support frame 91 via a second hinge pin 96. A first torsion spring 97 is sleeved on the first hinge pin 95 to drive the active clamping arm 92 to rotate toward the driven clamping arm 93. A second torsion spring 98 is sleeved on the second hinge pin 96 to drive the driven clamping arm 93 to rotate toward the active clamping arm 92, so that the active clamping arm 92 and the driven clamping arm 93 together clamp the test tube. The active clamping arm 92 is provided with two first clamping wheels 921 at intervals for adhering to the test tube wall, and the driven clamping arm 93 is provided with two second clamping wheels 931 at intervals for adhering to the test tube wall. A drive mechanism 94 is mounted on a support frame 91 to drive the active clamping arm 92 and the driven clamping arm 93 to open away from each other. The support frame 91 is equipped with a detection optocoupler 945 for detecting the position of the drive cam 943. Through the coordinated action of the active clamping arm 92 and the driven clamping arm 93, the test tube can be effectively clamped and fixed, preventing it from shaking or tilting during sample aspiration. The active clamping arm 92 and the driven clamping arm 93 are connected to the support frame 91 by a hinge, a design that allows the clamping arms to rotate freely within a certain range to accommodate test tubes of different diameters. The placement of a first torsion spring 97 and a second torsion spring 98 further enhances the elasticity of the clamping arms, ensuring that they maintain appropriate clamping force at all times. The two clamping rollers respectively mounted on the active clamping arm 92 and the driven clamping arm 93 are a key design feature. These four rollers can simultaneously contact the test tube surface at multiple points, providing a more uniform and stable clamping force. The design of the clamping rollers also reduces friction with the test tube surface, lowering the risk of damage. When the test tube needs to be released, the drive mechanism 94 can drive the active clamping arm 92 and the driven clamping arm 93 away from each other, thereby opening the clamping device. In practical applications, this single-tube positioning device 9 can work in conjunction with other components of the delivery line. For example, after the test tube enters the system through the sample inlet track 2, the single-tube positioning device 9 can accurately position and fix the test tube, providing a stable foundation for subsequent sample aspiration operations. This precise positioning not only improves the accuracy of sample aspiration but also reduces the risk of sample contamination or aspiration failure due to test tube misalignment. The first clamping roller 921 and the second clamping roller 931 can be made of elastic materials, such as silicone or rubber, to increase friction with the test tube and reduce damage to the test tube.

[0048] In this embodiment, the drive mechanism 94 includes a main drive arm 941, a driven arm 942, a drive cam 943, and a third drive motor 944. The third drive motor 944 is mounted on a support frame 91, and its output shaft is connected to the drive cam 943. The front end of the main drive arm 941 is hinged to a first hinge shaft 95 and fixed to an active clamping arm 92. The rear end of the main drive arm 941 is connected to the drive cam 943 to drive the active clamping arm 92 to open. The front end of the driven arm 942 is hinged to a second hinge shaft 96 and fixed to a driven clamping arm 93. The rear end of the driven arm 942 is connected to the main drive arm 941 to drive the driven clamping arm 93 to open. A first roller 9411 is rotatably provided at the rear end of the main drive arm 941, and the first roller 9411 abuts against the outer periphery of the drive cam 943. A second roller 9421 is rotatably mounted at the rear end of the drive arm 942, and a guide step 9412 abuts against the second roller 9421 on the main drive arm 941. In practical applications, when it is necessary to clamp the test tube, the third drive motor 944 drives the drive cam 943 to rotate to a specific position, so that the main drive arm 941 and the driven drive arm 942 are in a relaxed state. At this time, under the action of the first torsion spring 97 and the second torsion spring 98, the active clamping arm 92 and the driven clamping arm 93 will automatically close, clamping the test tube through the first clamping wheel 921 and the second clamping wheel 931. When it is necessary to release the test tube, the third drive motor 944 drives the drive cam 943 to rotate, and through the action of the main drive arm 941 and the driven drive arm 942, the active clamping arm 92 and the driven clamping arm 93 will open, thereby releasing the test tube. This design has the following advantages: First, the use of the drive cam 943 allows for more precise motion control, enabling precise positioning and smooth movement of the clamping arms. Secondly, the design of the main drive arm 941 and the driven arm 942 ensures the synchronous movement of the two clamping arms, improving the stability and reliability of the clamping. Furthermore, the use of the first torsion spring 97 and the second torsion spring 98 provides the clamping arms with initial clamping force, ensuring stable clamping of the test tube when no external force is applied. As a preferred embodiment, the drive cam 943 can be designed in an elliptical or specific non-circular profile to achieve more precise motion control.

[0049] Compared with the prior art, the single-tube positioning device 9 of this application has significant advantages in the following aspects:

[0050] 1. Precise control: By using the combination of drive cam 943 and transmission arm, precise control of the opening and closing of clamping arm is achieved. Compared with the traditional cylinder or electromagnet drive method, the control precision of this application is higher and the movement is smoother.

[0051] II. Synchronous Movement: The design of the main drive arm 941 and the driven arm 942 ensures the synchronous movement of the two clamping arms, avoiding the asynchronous problems that may occur in traditional designs and improving the stability of clamping.

[0052] 3. Adaptive clamping: By using the first torsion spring 97 and the second torsion spring 98, the device of this application can adapt to test tubes of different diameters, ensuring clamping force while reducing the risk of damage to the test tubes.

[0053] See also Figure 10 In this embodiment, at least one positioning fork device 20 is installed on the main body 1 of the conveyor line. The positioning fork device 20 includes a fourth drive motor 201, a mounting base 202, a fork member 203, a gear 204, and a rack 205. The fourth drive motor 201 is fixed below the main body 1 of the conveyor line via the mounting base 202. The output shaft of the fourth drive motor 201 is connected to the gear 204. Two racks 205 are provided, each meshing with one side of the gear 204. The two racks 205 slide vertically on the main body 1 of the conveyor line. Each rack 205 is provided with a fork member 203. Specifically, after the fourth drive motor 201 starts, it drives the gear 204 to rotate via its output shaft. Since the two racks 205 are meshed with one side of the gear 204, the rotation of the gear 204 drives the two racks 205 to move in opposite directions. The fork members 203 on the racks 205 move up and down accordingly, thus blocking or releasing the sample. The positioning fork device 20 is designed to provide precise positioning and blocking functions during sample transport, preventing sample displacement or jamming. As a preferred embodiment, the positioning fork device 20 can be installed at key locations on the sample infeed track 2, sample outlet track 3, or sample suction track 4. For example, the positioning fork device 20 can also be installed on the sample suction track 4, used in conjunction with the single-tube positioning device 9, to further improve the accuracy of sample positioning. The introduction of the positioning fork device 20 significantly improves the positioning accuracy and transport efficiency of the sample during transport.

[0054] The working principle of this application can be described as follows: First, the sample enters the system through the sample inlet track 2, and the positioning optocoupler 5 detects whether the sample has reached the designated position. The sample is transported to the rear end of the sample inlet track 2, and the transfer component 6 moves the sample from the sample inlet track 2 to the sample outlet track 3. The identification sensor 10 reads the sample information and establishes a signal connection with the transfer-in component 7. Based on the identification result, the transfer-in component 7 moves the sample to be tested from the sample outlet track 3 into the sample suction track 4. On the sample suction track 4, the single-tube positioning device 9 precisely positions the sample to ensure the accuracy of subsequent testing operations. After the test is completed, the transfer-out component 8 moves the sample from the sample suction track 4 to the sample outlet track 3, completing the entire transport process.
