Description

An automated sample loading device, laboratory system and working method Technical Field

[0001] This invention relates to an automatic sample loading device, a laboratory system, and a working method, belonging to the field of experimental equipment technology. Background Technology

[0002] In intelligent sample testing systems, sample transfer and analysis are crucial links in the laboratory automation process. Traditional laboratory systems primarily rely on a single-tube approach as the basic unit for sample transfer. The sample is placed in a test tube, which is then mounted on a single-tube holder. When the holder carrying the single tube moves to the branch track containing the sample analysis or processing equipment, a series of experimental steps and analytical items are completed. While this method achieves a degree of automation, its efficiency is limited when processing large numbers of samples.

[0003] To improve efficiency, existing technologies have been improved by designing test tube racks. Each rack has multiple tube holders, allowing it to support multiple test tubes simultaneously, thus enabling a single rack to hold multiple samples. These racks are also reusable. By placing test tubes on the racks, samples can be transported in rows to analytical equipment for testing, significantly improving sample processing efficiency. Correspondingly, some analytical devices and laboratory automation systems using test tube racks as transfer units have emerged on the market. However, despite these advancements, existing technologies still have many shortcomings in sample transfer within intelligent laboratory systems:

[0004] First, for existing independent analytical equipment in the laboratory, due to limitations in equipment structure, experimental procedures, regulations, or quality systems, it is often impossible to adapt and integrate it into the laboratory automation system. As a result, these devices can only be used as stand-alone units and cannot fully realize their potential value.

[0005] Secondly, the original test tube racks for different laboratory equipment often vary in size; some racks come with eight tube wells, while others have ten. When test tubes need to be moved between these different pieces of equipment, robotic arms or other sample transfer devices are typically used to repeatedly move the tubes to the corresponding racks. However, these sample transfer devices are generally bulky and occupy too much laboratory space, which not only increases the difficulty of laboratory layout but also further increases equipment costs.

[0006] Furthermore, laboratories typically require test tube racks to randomly enter and exit sample analysis and processing equipment or corresponding experimental nodes. After processing samples at a node, the racks should be able to return to the transport line and proceed to the next node, until the final destination. However, current technologies often fail to achieve this flexible flow, limiting the level of laboratory automation. For example, in some laboratories, due to the complexity of experimental procedures, it is necessary to simultaneously transport samples from different flow units, such as microplates, test tubes, and test tube racks. Current technologies, especially the adaptability of the transport lines themselves, often struggle to meet these diverse needs, leading to interruptions or inefficiencies in the experimental process.

[0007] These issues not only affect the level of automation and efficiency of the laboratory, but also limit the flexible use of laboratory equipment and space optimization.

[0008] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present invention, and therefore may include information that does not constitute prior art. Summary of the Invention

[0009] The purpose of this invention is to provide a new technical solution to improve or solve the technical problems existing in the prior art as described above.

[0010] The technical solution provided by the present invention is as follows: an automatic sample loading device, comprising an adapter base plate, a sample transfer device, a transfer slide, a docking frame, and an experimental carrier, wherein the transfer slide and the docking frame are both disposed on the adapter base plate, the experimental carrier can dock on the docking frame, and the experimental carrier is located on the transport path of the transfer slide, and the sample transfer device is used to transfer the sample carrier to the experimental carrier or remove it from the experimental carrier via the transfer slide.

[0011] Compared with the prior art, the technical solution provided by this invention has the following beneficial effects: The automatic sample loading device of this invention can be directly assembled onto the workbench of various experimental equipment, so that the transfer of test tubes between different equipment no longer relies on sample transfer devices such as robotic arms to repeatedly transfer them on different test tube racks. This not only ensures that test tubes can be transferred smoothly between different experimental equipment, but also achieves the adaptability and compatibility of the equipment with the full laboratory automation solution without changing the original intended use of the laboratory equipment, thereby greatly improving the use value and efficiency of the equipment.

[0012] Based on the above technical solution, the present invention can be further improved as follows.

[0013] Furthermore, the sensing triggering component includes a sensing rod, a connecting block, a telescopic column, a spring II, and a sensing block. One end of the sensing rod is close to the experimental carrier docking frame, and the other end of the sensing rod is connected to the connecting block. One end of the telescopic column is connected to the connecting block, and the other end of the telescopic column is equipped with the sensing block. The spring II is sleeved on the telescopic column.

[0014] The beneficial effect of adopting the above-mentioned further solution is that when the experimental carrier is docked on the docking rack, the sensor can be triggered by the inductive triggering component, thereby ensuring that the system can accurately identify the docking status of the experimental carrier. When the experimental carrier is removed from the docking rack, the elastic tension of spring II will cause the sensing block to return to its initial position and separate from the sensor. By triggering the sensor on the laboratory equipment workbench through the inductive triggering component to detect whether the experimental carrier is docked in place on the docking rack, it can achieve adaptability and compatibility of the equipment to a full laboratory automation solution without changing the original sensor position and structure of the laboratory equipment, thereby maximizing the use value of the equipment.

[0015] Furthermore, the experimental frame includes a frame body, a fulcrum rod, a pressure roller, and a spring I. The frame body has a mounting groove, and the two side walls of the mounting groove are provided with locking slots. The fulcrum rod is mounted on the frame body via a rotating shaft. The head of the fulcrum rod is provided with a locking tongue, and the pressure roller is rotatably mounted on the tail of the fulcrum rod. One end of the spring I is connected to the frame body, and the other end of the spring I is connected between the locking tongue of the fulcrum rod and the rotating shaft.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the mounting slot on the experimental frame and the locking slots on both sides can cooperate with the guide wings on both sides of the test tube rack, so that the test tube rack can be stably placed in the mounting slot of the experimental frame. In this way, the test tube rack can not only be supported on the workbench by the experimental frame, but also collect information by moving the experimental frame. The head of the fulcrum rod is provided with a locking tongue. When the test tube rack is stopped in the mounting slot of the experimental frame, under the tension of spring I, the locking tongue locks the test tube rack. The baffles on both sides of the locking tongue form a locking position with the test tube rack installed in the mounting slot, preventing the test tube rack from shifting or tipping. When it is necessary to release the limit, push the test tube rack towards the stop frame. During the pushing process, the stop frame presses down the pressure wheel, causing the tail of the fulcrum rod to press down, thereby causing the head of the fulcrum rod to lift up, and then separating the locking tongue from the test tube rack, realizing the cancellation of the limit.

[0017] Furthermore, the bottom of the carrier body is provided with a row of meshing teeth.

[0018] Furthermore, the docking frame includes a push rod and a limiter. The limiter can cooperate with the experimental frame and restrict its movement. The push rod can push the locking tongue of the fulcrum rod to lift up by pressing the pressure roller.

[0019] The beneficial effect of adopting the above-mentioned further solution is that when the experimental carrier moves close to the docking frame, the limiter and the experimental carrier form a limit in the Y-axis direction, ensuring that the experimental carrier is firmly fixed in the docking position and avoiding displacement of the experimental carrier due to misoperation or external interference; at the same time, the push rod can press the pressure roller, move the locking tongue of the fulcrum rod to lift up, so that the locking tongue is separated from the test tube rack, canceling the limitation of the locking tongue on the experimental carrier in the X-axis direction, and the test tube rack can move freely in the mounting slot.

[0020] Furthermore, the sample transfer device is a bidirectional telescopic device, which includes a base, an active telescopic component, a linked telescopic component, a transmission mechanism, a linkage mechanism, and a forward and reverse reversible drive motor. The base, the active telescopic component, and the linked telescopic component are arranged sequentially from bottom to top. The transmission mechanism is located between the base and the active telescopic component. The drive motor drives the active telescopic component to perform bidirectional telescopic movement along the length direction through the transmission mechanism. The linkage mechanism can drive the linked telescopic component to simultaneously telescopically move along the movement direction of the active telescopic component.

[0021] The beneficial effect of adopting the above-mentioned further solution is that the bidirectional telescopic device can extend and retract in two directions. When it is necessary to move test tube racks or microplates from the experimental carrier of laboratory equipment to the moving carrier, or from the moving carrier to the experimental carrier on the equipment, the bidirectional telescopic device can be used for pushing and receiving. The bidirectional telescopic device can realize the bidirectional telescopic movement of the entire bidirectional telescopic device through a single drive motor, which not only simplifies the structure of the device but also reduces manufacturing costs.

[0022] A laboratory system includes laboratory equipment, a movable carrier, a conveyor line, and an automatic sample loading device. The conveyor line is located on one side of the laboratory equipment, and the laboratory equipment is equipped with a workbench. The conveyor line and the workbench are connected by a transfer slide. The movable carrier is located on the conveyor line and can reciprocate along the conveyor line. The laboratory equipment is equipped with a workbench, and an adapter base plate is mounted on the workbench.

[0023] Compared with the prior art, the technical solution provided by this invention has the following advantages: The laboratory system of this invention enables the equipment to be adapted and compatible with a fully automated laboratory solution without changing its original intended use, thereby enhancing the equipment's usability. Simultaneously, it allows for the direct processing of batches of samples at the same time, reducing the cumbersome process of transferring and exchanging test tubes individually.

[0024] Based on the above technical solution, the present invention can be further improved as follows.

[0025] Furthermore, the workbench is also equipped with a drive gear set and a data acquisition device. The bottom of the experimental frame is provided with a meshing gear set for meshing with the drive gear set. The drive gear set can pull the experimental frame out from the docking frame and can also push the experimental frame back to its original position. The data acquisition device is used to collect data on the test tubes loaded on the experimental frame.

[0026] Furthermore, the moving frame includes a moving body and two sets of side plates disposed opposite to each other on the moving body. Each set of side plates has a sliding groove on one side facing each other. At least one of the sliding grooves has a flared opening at one or both ends, and the sliding groove protrudes inward relative to the inner wall of the side plate.

[0027] The beneficial effect of adopting the above-mentioned further solution is that the flared opening facilitates the smooth sliding of the sample rack, and the groove protrudes inward relative to the inner wall of the side plate to prevent the test tube rack from contacting the inner wall of the side plate when it slides between the side plates along the groove.

[0028] Furthermore, the two grooves have a height difference.

[0029] The advantage of adopting the above-mentioned further solution is that it can ensure that the test tube rack is loaded in the correct direction and prevent it from being installed backwards.

[0030] Furthermore, it also includes a test tube rack, which has multiple test tube hole seats. Both ends of the test tube rack are provided with guide wings for cooperating with the slide groove. The two guide wings have a height difference. The test tube rack can slide along the slide groove on the moving sub-carrier frame, and the bottom of the test tube rack does not contact the bottom of the moving sub-carrier frame. The bottom of the test tube rack is provided with a groove for placing an identification code.

[0031] The beneficial effect of adopting the above-mentioned further solution is that the two guide wings have a height difference, which can ensure that the test tube rack is loaded in the correct direction and prevent it from being installed backwards. The bottom of the test tube rack does not contact the bottom of the moving sub-carrier. When the test tube rack is installed on the moving sub-carrier, the test tube rack is in a suspended state, that is, the bottom of the test tube rack does not contact the lower support plate of the moving sub-carrier, thus avoiding friction.

[0032] Furthermore, a tower-type buffer device is provided between the conveyor line and the laboratory equipment, which is used to temporarily store the sample tubes to be analyzed.

[0033] The beneficial effect of adopting the above-mentioned further solution is that the tower-type buffer device can serve as a transfer station for sample tubes. When the conveyor line delivers sample tubes to the tower-type buffer device, the device can quickly receive and properly store these tubes. At the same time, when laboratory equipment requires new sample tubes for analysis, the tower-type buffer device can also respond quickly and deliver the required tubes to the equipment. Through the tower-type buffer device, the efficiency of sample processing can be improved.

[0034] Furthermore, the transfer chute is also equipped with a reader / writer for tracking the sample carriers transferred from the transfer chute.

[0035] A method for operating a laboratory system, comprising the following steps:

[0036] The carrier moves along the conveyor line to one side of the laboratory equipment;

[0037] The experimental carrier is docked on the docking rack;

[0038] The sample transfer device is activated, which moves the sample rack on the moving carrier to the experimental carrier via the transfer slide, or transfers the sample rack on the experimental carrier to the moving carrier.

[0039] The drive gear moves to a position corresponding to the bottom of one of the experimental frames and engages with the meshing gear set at the bottom of the experimental frame.

[0040] The drive gear rotates, and by using its meshing action with the meshing gear row, the experimental frame is pulled out from the docking frame to a position where information can be collected;

[0041] Alternatively, the drive gear can be reversed to push the experimental frame back to its original position on the docking frame in the opposite direction.

[0042] Furthermore, during the process of pulling out the experimental carrier for sample handling or pushing it back to its original position, the data acquisition device collects information from the samples on the experimental carrier.

[0043] The aforementioned laboratory system improves the automation and efficiency of sample processing and analysis. This method, through the coordinated movement of components such as the moving carrier, experimental carrier, bidirectional telescopic device, and drive gears, achieves smooth transfer of the sample rack from the conveyor line to the experimental carrier, as well as the positioning and movement of the experimental carrier between the docking station and the data acquisition position. The data acquisition equipment can collect information from the samples on the experimental carrier in real time, ensuring the accuracy and timeliness of sample analysis. This invention not only significantly reduces the steps and time required for manual operation, lowering labor costs, but also significantly improves the stability and reliability of sample processing. Through an automated workflow, it effectively avoids the risk of sample damage or loss caused by improper manual operation, ensuring the quality of sample analysis. Furthermore, this method can adapt to different specifications and types of experiments, meeting diverse sample analysis needs. Attached Figure Description

[0080] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and do not imply any priority in order or any specific technical meaning. Furthermore, the concepts of "connection" and "linkage" mentioned in this application, unless otherwise specified, are considered to include both direct connection (linkage) and indirect connection (linkage).

[0081] When interpreting the description of this application, it should be clarified that terms such as "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating directions or positional relationships, are based on the perspective and layout shown in the accompanying drawings. They are intended to facilitate explanation and simplify the description process, and are not absolute limitations on the actual location, construction method, or operating mode of the described device or element. Therefore, these terms should not be construed as restrictive interpretations of the content of this application.

[0082] The principles and features of the present invention are described below with reference to examples. The examples are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0083] Example 1:

[0084] As shown in Figures 1-16, a laboratory system includes laboratory equipment 300, a movable carrier 400, a conveyor line 500, an adapter base plate 600, an experimental carrier 200, a sample transfer device, a transfer slide 610, and a docking rack 620. The movable carrier 400 is located on the conveyor line 500 and can reciprocate along the conveyor line 500. The laboratory equipment 300 is arranged on either side of the conveyor line 500. A workbench 310 is provided on the laboratory equipment 300. The adapter base plate 600, the experimental carrier 200, the transfer slide 610, and the docking rack 620 are all installed on the workbench 310. The adapter base plate 600 is provided with a receiving area and an operating area. The transfer slide 610 is located in the receiving area, and its two ends extend to the conveyor line 500 and the operating area, respectively. One or more of the experimental racks 200 are arranged in the operating area. The experimental racks 200 can rest on the docking rack 620, and are located on the conveying path of the transfer slide 610. The sample transfer device can transfer the test tube racks 800 on the conveyor line 500 to the experimental racks 200 via the transfer slide 610, and can also transfer the test tube racks 800 on the experimental racks 200 back to the conveyor line 500 via the transfer slide 610. A stop bar is provided on the side of the experimental rack 200 away from the transfer slide 610 to prevent the test tube racks 800 from tilting when pulled out or pushed in.

[0085] In addition, in this embodiment:

[0086] As shown in Figures 1 and 6, the workbench 310 is also equipped with a drive gear set 320 and a data acquisition device 330. The bottom of the experimental carrier 200 is provided with a gear rack 211 for meshing with the drive gear set 320. The drive gear set 320 can pull the experimental carrier 200 out of the docking rack 620 and push the experimental carrier 200 back to its original position. When the experimental carrier 200 is pulled out, information can be collected using the data acquisition device 330. In addition, the user can directly load the test tube rack 800 onto the experimental carrier 200 from the pulled-out position, or remove the test tube rack 800 from the experimental carrier 200. If there is an empty docking position on the docking rack 620, the operator can also move the experimental carrier 200 loaded with the test tube rack 800 along the Y-axis direction to the empty docking position for loading. Compared to the limitations of existing laboratory equipment workbenches where the experimental carrier 200 can only be moved in one direction, this invention not only supports the function of picking up and placing the experimental carrier 200 in the Y-axis direction, but also has the function of transporting the experimental carrier 200 along the X-axis direction.

[0087] The drive gear set 320 includes two drive gears and a moving mechanism. The moving mechanism can drive the two drive gears and the data acquisition device 330 to move along the X-axis on the worktable 310.

[0088] Dock 620: As shown in Figures 7 and 8, the dock 620 has multiple docking positions, each of which is equipped with a push rod 621 and a limiter. In this embodiment, the limiter is a limit card 622, which can be inserted into the experimental carrier 200 and restrict its movement. More specifically, the limit card 622 has an arc-shaped protrusion 623, and the experimental carrier 200 has an arc-shaped groove 214 that cooperates with the arc-shaped protrusion 623. The arc-shaped protrusion 623 can be inserted into the arc-shaped groove 214 to restrict the movement of the experimental carrier 200. The push rod 621 can actuate the U-shaped locking tongue 222 of the experimental carrier 200 by pressing the pressure roller 221 at the end of the fulcrum rod 220. Of course, the docking rack 620 can also be provided with a docking position. The number of docking positions is adapted to the loading capacity of the experimental carrier rack 200. The number can be matched according to the size of the equipment and the usage requirements.

[0089] In another embodiment, as shown in Figures 15 and 16, the limiter is a ball bearing set screw 624, and the experimental carrier 200 is provided with a set screw groove 625 that cooperates with the ball bearing set screw 624. When the experimental carrier 200 is stopped on the stop frame, the ball bearing set screw 624 abuts against the set screw groove 625, thereby restricting the movement of the experimental carrier 200 along the Y-axis.

[0090] Experimental frame 200: As shown in Figures 9-13, it includes a frame body 210, a fulcrum rod 220, a pressure roller 221, and a spring I 223. The frame body 210 has a meshing toothed rack 211 at its bottom and a mounting groove 212. The mounting groove 212 has slots 213 on its two side walls. The fulcrum rod 220 is mounted on the frame body 210 via a rotating shaft. The head of the fulcrum rod 220 has a U-shaped locking tongue 222. Of course, the locking tongue can also be L-shaped or C-shaped, as long as it meets the limiting requirements. The pressure roller 221 is rotatably mounted on the tail of the fulcrum rod 220. One end of the spring I 223 is connected to the frame body 210, and the other end of the spring I 223 is connected between the locking tongue of the fulcrum rod 220 and the rotating shaft.

[0091] The U-shaped locking tongue 222 has flanges on both sides, and the width of the U-shaped locking tongue 222 is adapted to the width of the test tube rack 800. When the experimental carrier 200 is detached from the docking frame 620, the tension of the spring I 223 will pull the fulcrum rod 220, causing its head to press down, thereby causing the U-shaped locking tongue 222 to lock the test tube rack 800. At this time, the flanges on both sides of the U-shaped locking tongue 222 and the test tube rack 800 installed in the mounting groove 212 form a locking position, which can prevent the test tube rack 800 from shifting or tipping when the experimental carrier 200 moves along the Y-axis. Conversely, as shown in Figure 8, when the experimental carrier 200 stops at the docking frame 620, the push rod 621 on the docking frame 620 pushes the pressure roller 221, causing the tail of the fulcrum rod 220 to press down, thereby causing the head of the fulcrum rod 220 to lift up, separating the U-shaped locking tongue 222 from the test tube rack 800, canceling the limit, and allowing the test tube rack 800 to move freely along the X-axis on the experimental carrier 200. Simultaneously, the limiter cooperates with the carrier body 210 to prevent the carrier body 210 from moving along the Y-axis.

[0092] Induction trigger component 700: As shown in Figures 7 and 8, the induction trigger component 700 is disposed on the workbench 310. When the experimental carrier 200 is parked on the docking rack 620, the experimental carrier 200 can trigger the sensor on the workbench 310 through the induction trigger component 700, thereby detecting whether the experimental carrier 200 is parked in place on the docking rack 620. The sensing trigger assembly 700 includes a sensing rod 710, a connecting block 720, a telescopic column 730, a spring II 740, and a sensing block 750. The sensing rod 710 is slidably mounted below the adapter base plate 600. One end of the sensing rod 710 is close to the docking frame 620, and the other end of the sensing rod 710 is connected to the connecting block 720. One end of the telescopic column 730 is connected to the connecting block 720, and the sensing block 750 is mounted on the other end of the telescopic column 730. The spring II 740 is sleeved on the telescopic column 730, and both ends of the spring II 740 abut against the connecting block 720 and the adapter base plate 600, respectively.

[0093] When the experimental carrier 200 stops at the docking frame 620, the experimental carrier 200 touches the end of the sensing rod 710 and pushes the sensing rod 710 to move. The sensing rod 710 drives the telescopic column 730 and the sensing block 750 mounted on the telescopic column 730 to move closer to the sensor on the workbench 310. Once the sensing block 750 contacts the sensor on the workbench 310, the sensor immediately sends a signal to the control system. After receiving this signal, the control system can accurately determine that the experimental carrier 200 has stopped at the docking position. The experimental carrier 200 continues to move towards the docking frame 620, continuing to push the sensing rod 710 to move. The connecting block 720 compresses the spring II 740, and the sensing block 750 makes close contact with the sensor. When the experimental carrier 200 detaches from the docking frame 620, the spring II 740, under the action of restoring force, pushes the connecting block 720 to move in the opposite direction, thereby causing the sensing rod 710 and the telescopic column 730 to move in the opposite direction, and the sensing block 750 will separate from the sensor. At this time, the sensor will send a signal to the control system again. After receiving this signal, the control system can accurately determine that there is no longer an experimental carrier 200 docked at the docking position.

[0094] The moving tube carrier 400, as shown in Figures 17 and 18, includes a moving body 410 and two sets of side plates 420 disposed opposite to each other on the moving body 410. The moving body 410 is provided with a lower support plate, and a limiting groove can be provided on the lower support plate for supporting microplates. The microplate is an existing sample carrier. The lower support plate is located between the two sets of side plates 420. Each set of side plates 420 has a sliding groove 430 on one side facing each other. The two sliding grooves 430 have a height difference. At least one of the sliding grooves 430 has a flared opening at one or both ends to facilitate the smooth sliding of the sample holder. The sliding groove 430 protrudes inward relative to the inner wall of the side plate 420 to prevent the test tube holder 800 from contacting the inner wall of the side plate 420 when sliding between the side plates 420 along the sliding groove 430.

[0095] The moving carrier 400 also includes a braking assembly 440 for preventing the test tube rack 800 from slipping. The braking assembly 440 is disposed at the end of the side plate 420. The braking assembly 440 includes a positioning seat 441, a blocking claw 442, and a magnet. The positioning seat 441 is mounted on the side plate 420, and the blocking claw 442 is rotatably mounted on the positioning seat 441. The end of the blocking claw 442 has a hook-shaped protrusion. Opposite pole magnets are respectively installed on the opposite side of the blocking claw 442 and the positioning seat 441. The blocking claw 442 can be reset by the magnetic attraction between the magnets. When the test tube rack 800 is slid from one end to the other on the moving carrier 400, the guide wings 820 on both sides of the test tube rack 800 slide within the sliding grooves 430 on both sides of the moving carrier 400. When the test tube rack 800 slides to the end of the moving carrier 400, the hook-shaped protrusions at the ends of the blocking claws 442 can stop the test tube rack 800, acting as a stop to prevent the test tube rack 800 from slipping during movement; when it is necessary to unload... When the test tube rack 800 is in motion, the test tube rack 800 will continue to move along the slide 430 toward the end of the moving carrier 400, and in the process, it will push open the blocking claw 442. Since the resistance encountered by the blocking claw 442 at this time exceeds the magnetic attraction force of the magnet, the blocking claw 442 can overcome the magnetic attraction force and temporarily open, so as not to hinder the continued movement of the test tube rack 800. When the test tube rack 800 is moved away, the blocking claw 442 can be reset under the mutual attraction force of the opposite pole magnets.

[0096] In another embodiment, the braking assembly 440 includes a positioning seat 441, a blocking claw 442, and a torsion spring. The positioning seat 441 is mounted on the side plate 420, and the blocking claw 442 is rotatably mounted on the positioning seat 441 via a pivot. The end of the blocking claw 442 has a hook-shaped protrusion. The torsion spring is used to provide a reset force. The blocking claw 442 is connected via a pivot and is opened and closed by the action of the torsion spring. When encountering resistance, the blocking claw 442 will temporarily open against the elastic force of the torsion spring and then reset under the reset action of the torsion spring.

[0097] Test tube rack 800: As shown in Figure 14, the test tube rack 800 is provided with multiple test tube holders 810 for placing test tubes. The test tube rack 800 has guide wings 820 at both ends for engaging with the sliding grooves 430, namely a left guide wing 820 and a right guide wing 820. The two guide wings 820 have a height difference, ensuring that the test tube rack 800 is loaded correctly and preventing reverse installation. The left and right guide wings 820 of the test tube rack 800 engage with the sliding grooves 430 on the left and right sides of the moving carrier frame 400, respectively, allowing the test tube rack 800 to slide along the sliding grooves 430 on the moving carrier frame 400. Furthermore, the distance from the left-side slide groove 430 to the lower support plate at the bottom of the moving sub-carrier 400 is greater than the distance from the left-side guide wing 820 to the bottom of the test tube rack 800. Similarly, the distance from the right-side slide groove 430 to the lower support plate is greater than the distance from the right-side guide wing 820 to the bottom of the test tube rack 800. When the test tube rack 800 slides along the slide groove 430 between the moving sub-carriers 400, the test tube rack 800 can maintain a non-contact state with the lower support plate at the bottom of the moving sub-carrier 400. That is, when the test tube rack is mounted on the moving sub-carrier, the test tube rack is in a suspended state, avoiding friction caused by direct contact between the bottom of the test tube rack 800 and the lower support plate of the moving sub-carrier 400. When the test tube rack is mounted on a transfer slide or experimental carrier, it is also in a suspended state.

[0098] When the experimental carrier 200 is docked on the docking rack 620, and the movable carrier 400 moves along the conveyor line 500 to one side of the sample laboratory equipment 300, the transfer slide 610, the movable carrier 400, and the experimental carrier 200 are connected. Through the sample transfer device, the sample carrier on the movable carrier 400 can be transferred to the experimental carrier 200 via the transfer slide 610, and similarly, the sample carrier on the experimental carrier 200 can be moved to the movable carrier 400 via the transfer slide 610. The transfer slide 610 is also equipped with a reader / writer. In addition to the identification code on the bottom of the test tube rack 800, the identification code can be an RFID tag, barcode, or other form of identifiable marker. The reader / writer can track the test tube rack 800 passing over the transfer slide 610.

[0099] In this embodiment, the sample transfer device adopts a bidirectional telescopic device 100. The sample transfer device can also adopt other forms, such as a truss transfer device or a robotic arm.

[0100] As shown in Figures 24-34, the bidirectional telescopic device 100 includes a base 101, an active telescopic member 102, a linked telescopic member 103, a transmission mechanism, a linkage mechanism, and a forward and reverse reversible drive motor 111. The base 101, the active telescopic member 102, and the linked telescopic member 103 are arranged sequentially from bottom to top. The transmission mechanism is located between the base 101 and the active telescopic member 102. The drive motor 111 drives the active telescopic member 102 to perform bidirectional telescopic movement along the length direction through the transmission mechanism. The linkage mechanism can drive the linked telescopic member 103 to simultaneously telescopically move along the movement direction of the active telescopic member 102.

[0101] Furthermore, the transmission mechanism of the bidirectional telescopic device 100 includes a main shaft 105, a first worm gear mechanism 116, a second worm gear mechanism 117, and a rack 106. The main shaft 105 is rotatably mounted on the base 101 and is driven to rotate by the drive motor 111. In this embodiment of the invention, the transmission connection between the drive motor 111 and the main shaft 105 is not limited; power can be transmitted between the drive motor 111 and the main shaft 105 via chain drive, belt drive, or gear drive. The rack 106 is mounted on the active telescopic member 102 and its sliding direction is consistent with that of the active telescopic member 102. The first worm gear mechanism 116 and the second worm gear mechanism 117 are respectively disposed at both ends of the main shaft 105 and, through their forward and reverse rotational cooperation with the main shaft 105, transmit power to the rack 106. The movement of the rack 106 then drives the active telescopic member 102 to achieve bidirectional telescopic movement. When the drive motor 111 starts and drives the main shaft 105 to rotate, the first worm gear mechanism 116 and the second worm gear mechanism 117 will operate synchronously. During the movement, the rack 106 will maintain a transmission relationship with at least one of the two worm gear mechanisms, so that the active telescopic member 102 can extend and retract along the length direction of the rack 106. In addition to the extension length of the linkage telescopic member 103, when the bidirectional telescopic device 100 is extended to the limit position on one side, its total unidirectional extension length is equal to the sum of the lengths of the active telescopic member 102, the linkage telescopic member 103 and the base 101, minus the length of the overlapping part designed for the added support between the active telescopic member 102 and the linkage telescopic member 103, and between the active telescopic member 102 and the base 101. Therefore, by designing a smaller overlapping part size, the telescopic range of the bidirectional telescopic device 100 can be effectively expanded. In addition, the drive motor 111 can drive the main shaft 105 to rotate in both directions, ensuring that the active telescopic member 102 can perform bidirectional telescopic movement along the preset direction. This not only improves the flexibility and practicality of the bidirectional telescopic device 100, but also further improves its working efficiency and stability.

[0102] More specifically, in the initial state, the active telescopic member 102 is located directly above the base 101, and the linkage telescopic member 103 is vertically opposite to the active telescopic member 102. The two ends of the rack 106 are respectively engaged with the first worm gear mechanism 116 and the second worm gear mechanism 117. When the drive motor 111 drives the main shaft 105 to rotate forward, in the initial stage, the first worm gear mechanism 116 and the second worm gear mechanism 117 simultaneously engage with the rack 106, pushing the active telescopic member 102 to move away from the second worm gear mechanism 117. As the active telescopic member 102 moves, the rack 106 gradually disengages from the second worm gear mechanism 117, but continues to maintain engagement with the first worm gear mechanism 116. At this time, the first worm gear mechanism 116 continues to transmit power to the rack 106 through its rotational engagement with the main shaft 105, pushing the active telescopic member 102 to continue moving away from the second worm gear mechanism 117 until it reaches a set position and stops. When the active telescopic member 102 needs to move in the opposite direction, the drive motor 111 is activated to rotate in the opposite direction, and the main shaft 105 will rotate in the opposite direction. At this time, the rack 106 and the first worm gear mechanism 116 are still engaged, and the first worm gear mechanism 116 will push the active telescopic member 102 to move closer to the second worm gear mechanism 117. As the active telescopic member 102 moves in the opposite direction, it returns to its initial state. At this time, the first worm gear mechanism 116 and the second worm gear mechanism 117 simultaneously engage with the rack 106. Then, the rack 106 gradually disengages from the first worm gear mechanism 116 while maintaining engagement with the second worm gear mechanism 117. Subsequently, the second worm gear mechanism 117, through its rotational engagement with the main shaft 105, transmits power to the rack 106. The movement of the rack 106 then drives the active telescopic member 102 to move away from the first worm gear mechanism 116. Therefore, by controlling the rotational direction of the drive motor 111, the bidirectional telescopic movement of the active telescopic member 102 can be achieved.

[0103] The linkage mechanism is responsible for driving the linkage telescopic member 103 to extend and retract synchronously along the movement direction of the active telescopic member 102. The linkage mechanism includes a first transmission belt 107 and a second transmission belt 108, as shown in Figure 29. One end of the first transmission belt 107 is fixed to the left side of the base 101, and after passing around the first pulley 109 installed at the right end of the active telescopic member 102, it is connected to the left side of the linkage telescopic member 103; as shown in Figure 30, one end of the second transmission belt 108 is fixed to the right side of the base 101, and after passing around the second pulley 110 installed on the left side of the linkage telescopic member 103, it is connected to the right side of the linkage telescopic member 103; as shown in Figure 31. When the active telescopic member 102 moves to the right, the first pulley 109 pushes the first transmission belt 107 to extend to the right, causing the first transmission belt 107 to drive the linked telescopic member 103 to move to the right synchronously. Simultaneously, as shown in Figure 32, the second transmission belt 108 is also dragged to the right by the linked telescopic member 103 and extends synchronously. As shown in Figure 34, when the active telescopic member 102 moves to the left, the second pulley 110 pushes the second transmission belt 108 to extend to the left, causing the second transmission belt 108 to drive the linked telescopic member 103 to move to the left synchronously. Simultaneously, as shown in Figure 33, the first transmission belt 107 is also dragged to the left by the linked telescopic member 103 and extends synchronously. Through this linkage mechanism, the linked telescopic member 103 can maintain the same direction of movement as the active telescopic member 102, achieving synchronous telescopic extension and retraction.

[0104] The linkage telescopic component 103 is provided with loading levers 104 on one or both sides. The levers can push the test tube rack 800 to move, thereby facilitating the loading and unloading of test tubes. When loading levers 104 are provided on both sides of the linkage telescopic component 103, the test tube rack can be moved on one side and the microplate can be moved on the other side.

[0105] The procedure for loading test tubes using the aforementioned laboratory system is as follows:

[0106] First, multiple experimental racks 200 are docked on the docking rack 620. When an experimental rack 200 successfully docks in its designated position on the docking rack 620, a corresponding sensing component is triggered. This sensing component activates a sensor on the workbench 310. Upon receiving a signal, the sensor sends a signal to the control system. Upon receiving this signal, the control system can accurately determine that an experimental rack 200 has been docked in that position. The number of experimental racks 200 can be set according to the maximum loading requirements of the test tube racks, and this number will vary depending on the size of the compatible equipment. Alternatively, the number of experimental racks can be equal to or greater than the maximum number of test tube racks that the moving rack can support.

[0107] Then, the drive motor 111 of the bidirectional telescopic device 100 is started, causing the main shaft 105 to start rotating. Through the transmission of the worm gear mechanism and rack 106, the active telescopic member 102 moves towards the conveyor line side. At the same time, the linkage mechanism drives the linkage telescopic member 103 to extend synchronously towards the conveyor line side. When the linkage telescopic member 103 drives the loading lever 104 to reach the conveyor line, the loading levers 104 on both sides of the linkage telescopic member 103 span across both sides of the conveyor line, and the drive motor 111 stops, waiting for the arrival of the moving carrier 400.

[0108] At this time, the test tube to be tested is placed in the test tube hole seat 810 of the test tube rack 800, and the movable carrier 400 carries the test tube rack 800 and moves on the conveyor line 500. When the movable carrier 400 moves along the conveyor line to dock with the transfer slide 610, it stops moving, and at this time the test tube rack is located between the loading levers 104;

[0109] Next, the drive motor 111 of the bidirectional telescopic device 100 is started to rotate in the opposite direction, and the active telescopic component 102 is pushed to move away from the conveyor line through the meshing transmission of the worm gear mechanism and the rack 106. At this time, the loading lever 104 clamps the test tube rack 800 and moves it towards the laboratory equipment 300 until it reaches the mounting slot 212 of the experimental carrier 200, after which the drive motor 111 stops working.

[0110] During the information acquisition phase, when the drive gear moves to the bottom of one of the experimental carriers 200, the drive gear meshes with the meshing gear set 211 at the bottom of the experimental carrier 200. The rotation of the drive gear pulls the experimental carrier 200 out of the docking frame 620 along the X-axis. Subsequently, the drive gear reverses, pushing the experimental carrier 200 back to its original position. During the process of the experimental carrier 200 being pulled out or pushed back, the data acquisition device 330 (such as a barcode scanner, scanner, or camera) completes information acquisition, and the system verifies and records the transmitted sample information. Subsequently, the laboratory equipment 300 begins pipetting, that is, aspirating the liquid in the test tube onto other carriers for analysis.

[0111] The drive gear can pull the experimental rack 200 along the X-axis to the information collection area for scanning / photographing, starting from either the first or last row. Alternatively, it can prioritize scanning / photographing a specific test tube rack 800. For example, after scanning the test tubes on the first experimental rack 200, the rack returns to the operating area, and the pipetting channel of the laboratory equipment 300 begins to aspirate samples from the test tubes on the first rack into other carriers of the equipment for testing. Simultaneously, the second experimental rack 200 is pulled out, and scanning, returning to its original position, and aspirating begin, and so on. Scanning and aspiration can be performed synchronously to improve analytical efficiency.

[0112] After the inspection is completed, the test tube rack 800 needs to be returned to the conveyor line. At this time, the drive motor 111 is restarted, and the shaft 105 rotates, pushing the active telescopic component 102 to move towards one side of the conveyor line through the worm gear mechanism and rack 106. Simultaneously, the linkage mechanism drives the linkage telescopic component 103 to move synchronously towards one side of the conveyor line. The loading lever 104 clamps the test tube rack 800 and moves it towards one side of the conveyor line until it is transported back to the moving carrier 400 on the conveyor line. After the drive motor 111 stops working, the moving carrier 400 will carry the test tube rack 800 along the conveyor line to the next inspection station. The bidirectional telescopic device 100 then waits for the arrival of the next moving carrier 400.

[0113] Transfer slides 610 can be provided on one or both sides of the bidirectional telescopic device 100. When loading levers 104 are provided on both sides of the linkage telescopic member 103, the sample carrier can be transferred along the transfer slide 610 on either side via the bidirectional telescopic device 100. For example, one transfer slide 610 can be used to transfer experimental microplates, and the other transfer slide 610 can be used to transfer test tube racks 800. The bidirectional telescopic device 100 can transfer sample carriers simultaneously or separately through the transfer channels on both sides. In this way, the laboratory system has the ability to transport microplates and test tube racks 800 simultaneously, further improving experimental efficiency.

[0114] Example 2:

[0115] Unlike Embodiment 1, a tower-type buffer device 900 is also provided between the conveyor line 500 and the laboratory equipment 300. The tower-type buffer device 900 is used to temporarily store the sample tubes to be analyzed. In this embodiment, the bidirectional telescopic device 100 is installed on the tower-type buffer device 900.

[0116] More specifically, as shown in Figures 19-23, the tower-type buffer device 900 includes a tower 901, a tray 902, a back plate 903, an electric cylinder 904, and a linear lifting assembly 905. The electric cylinder 904 is mounted on the tower 901, and its output shaft is rotatably connected to the lead screw of the linear lifting assembly 905. The back plate 903 is mounted on the inner wall of the tower 901 in a liftable manner via the linear lifting assembly 905. Multiple trays 902 are spaced apart from top to bottom on the back plate 903.

[0117] Furthermore, the transfer chute 610 includes a front transfer chute 913 and a rear transfer chute 914, which are respectively installed on both sides of the tower 901. The front transfer chute 913 extends to the operating area of ​​the laboratory equipment 300, and the rear transfer chute 914 connects to the conveyor line. When a tray 902 on the back plate 903 moves up and down to the same corresponding height as the front transfer chute 913 and the rear transfer chute 914, the outlet of the tray 902 near the laboratory equipment 300 can connect with the front transfer chute 913 so that the sample carrier can be moved in or out from the front outlet; the outlet of the tray 902 near the conveyor line 500 can connect with the rear transfer chute 914 so that the sample carrier can be moved in or out from the rear outlet. The front transfer chute 913 is also equipped with a reader / writer for tracking sample carriers, such as test tube racks 800, transferred from the front transfer chute 913. Based on the identification code affixed to the bottom of each test tube rack 800, when these sample carriers are transferred via the front transfer chute 913 to the tray 902 of the tower-type buffer device 900, the reader / writer on the tray 902 automatically reads the identification code on the bottom of the test tube rack 800. This not only enables real-time tracking and monitoring of the test tube racks 800 but also facilitates the management of inventory test tube racks 800. Through the automatic reading and recording of the reader / writer, the system can update information such as the location, quantity, and status of the test tube racks 800 in real time, providing a more intelligent and reliable storage and tracking solution for laboratories, medical institutions, and research units.

[0118] In this embodiment, the bidirectional telescopic device 100 is installed on the tower 901 via a lifting mechanism 112. Specifically, the lifting mechanism 112 includes a lifting motor 113, a lifting plate 114, and a base plate 115. The cylinder of the lifting motor 113 is fixed on the base plate 115, and the base plate 115 is fixed on the tower 901. The telescopic shaft of the lifting motor 113 is connected to the lifting plate 114. The base 101 of the bidirectional telescopic device 100 is installed above the lifting plate 114. The extension and retraction of the telescopic shaft of the lifting motor 113 can drive the bidirectional telescopic device 100 to rise and fall.

[0119] The tower-type buffer device 900 further includes a blocking mechanism, which is linked to the lifting mechanism 112. The blocking mechanism includes a first guide rail 916, a first slide 917, a transmission gear set 918, a second slide 919, and a second guide rail 920. The first guide rail 916 and the second guide rail 920 are arranged parallel to each other on the tower 901. The transmission gear set 918 is rotatably mounted on the tower 901. The first slide 917 is slidably mounted on the first guide rail 916 and connected to the base 101 of the bidirectional telescopic device. The first slide 917 can be linked with the bidirectional telescopic device 100. The first slide 917 is provided with an active rack. The second slide 919 is slidably mounted on the second guide rail 920 and is provided with a passive rack. The active rack and the passive rack are meshed and transmitted through the transmission gear set 918. When the base 101 rises under the drive of the lifting mechanism 112, it will drive the first slide 917 connected to it to move upward along the first guide rail 916. Through the meshing of the active rack and the transmission gear set 918, it will further drive the second slide 919 to rise along the second guide rail 920. As the second slide 919 rises, it will block the end of the tray 902, thereby effectively preventing the sample carrier stored on the tray 902 from falling off. Conversely, when the base 101 falls under the drive of the lifting mechanism 112, it will drive the first slide 917 connected to it to move downward along the first guide rail 916. Through the meshing of the active rack and the transmission gear set 918, it will further drive the second slide 919 to fall along the second guide rail 920. As the second slide 919 falls, it will move away from the end of the tray 902. At this time, if necessary, the sample carrier can be removed or placed on the tray 902. The blocking mechanism protects the sample carrier during storage, preventing it from falling off the tray 902 and being damaged, thus improving the safety and stability of the storage device.

[0120] A method of operating the aforementioned laboratory system, comprising the steps of:

[0121] The moving carrier 400 moves along the conveyor line 500 to one side of the laboratory equipment 300;

[0122] The experimental carrier 200 is docked on the docking frame 620;

[0123] The sample transfer device transfers the sample rack on the moving carrier 400 to the experimental carrier 200 via the transfer slide 610, or transfers the sample rack on the experimental carrier 200 to the moving carrier 400.

[0124] The drive gear moves to a position corresponding to the bottom of one of the experimental carriers 200, and the drive gear meshes with the meshing gear row 211 at the bottom of the experimental carrier 200.

[0125] The drive gear rotates, and by its meshing with the meshing gear row 211, the experimental carrier 200 is pulled out from the docking frame 620;

[0126] Reversing the drive gear can push the experimental frame 200 back to its original position on the docking frame 620 in the opposite direction.

[0127] During the process of the experimental carrier 200 being pulled out for sample handling or pushed back to its original position, the data acquisition device 330 collects information on the samples on the experimental carrier 200.

[0128] The detailed working method of the tower-type buffer device 900 for storing the test tube rack 800 according to this utility model is as follows:

[0129] First, the drive motor 111 of the bidirectional telescopic device 100 is started, which drives the main shaft 105 to rotate. Then, through the worm gear mechanism and rack 106, the active telescopic member 102 is pushed to move closer to the conveyor line. At the same time, the linkage mechanism drives the linkage telescopic member 103 to extend and retract synchronously with the active telescopic member 102. When the linkage telescopic member 103 moves to the conveyor line, the drive motor 111 stops working, and the loading lever 104 is straddling both sides of the conveyor line to wait for the arrival of the moving carrier 400 carrying the test tube rack 800 on the conveyor line.

[0130] Next, the drive cylinder of the tower-type buffer device 900 is activated, and the linear lifting component 905 drives the tray 902 on the back plate 903 to move up and down. After one of the empty trays 902 of the test tube rack 800 moves to the same height position as the front transfer slide 913 and the rear transfer slide 914, the drive cylinder stops working.

[0131] Subsequently, the test tubes to be tested are placed in the test tube hole seats 810 of the test tube rack 800. The movable carrier 400, carrying the test tube rack 800, moves along the conveyor line 500. When the movable carrier 400 moves along the conveyor line to between the loading levers 104, it stops. At this time, the drive motor 111 of the bidirectional telescopic device 100 is restarted. The drive motor 111 drives the main shaft 105 to rotate in the opposite direction, which in turn pushes the active telescopic member 102 to move away from the conveyor line through the worm gear mechanism and rack 106. The loading lever 104 clamps the test tube rack 800 to be transported and moves towards the tray 902. After moving onto the tray 902 through the front transfer slide 913 or the rear transfer slide 914, the drive motor 111 stops.

[0132] When the loading lever 104 of the bidirectional telescopic device 100 holds the sample carrier 800 and stops at any position, such as on the front transfer slide 913, the rear transfer slide 914, or the tray 902, if it is necessary to move the loading lever 104 from both sides of the sample carrier 800 to another position without moving the batch of sample carriers 800, the height of the loading lever 104 needs to be adjusted first. Since the base 101 is installed above the lifting plate 114, the entire bidirectional telescopic device 100 will rise and fall with the movement of the lifting plate 114. The lifting motor 113 is started to raise the bidirectional telescopic device 100 to a certain height. When the linkage telescopic component 103 and the loading lever 104 on it move up to a height higher than the test tubes on the test tube rack 800, the lifting motor 113 stops. At the same time, the blocking mechanism will be activated, and the second slide 919 will rise and block the end of the tray 902 to prevent the test tube rack 800 from falling off.

[0133] Then, the drive motor 111 of the bidirectional telescopic device 100 is restarted. The drive motor 111 drives the main shaft 105 to rotate, and the active telescopic component 102 moves to the side closer to the conveyor line. The linkage mechanism drives the linkage telescopic component 103 to extend and retract synchronously with the active telescopic component 102. When the linkage telescopic component 103 moves to the side of the test tube rack 800 carrier on the conveyor line, the drive motor 111 stops working. The lifting motor 113 is started to lower the bidirectional telescopic device 100 to the low position, and the loading lever 104 is once again straddled on both sides of the conveyor line, waiting for the arrival of the next moving carrier 400 carrying the test tube rack 800.

[0134] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
