Description

Technical Field

[0001] The invention relates to an automatic sample loading device, a laboratory system and a working method, and belongs to the technical field of laboratory equipment. Background Art

[0002] In the intelligent sample inspection system, the flow and analysis of samples are key links in the laboratory automation process. The traditional laboratory system mainly relies on the single-tube method as the basic unit of sample flow, that is, the sample is placed in a test tube, and the test tube is installed on a single-tube test tube holder. When the test tube holder carrying the single tube flows to the branch track where the sample analysis or sample processing equipment is located, a series of experimental steps and analysis items can be completed. Although this method has achieved automation to a certain extent, its efficiency is limited when processing a large number of samples.

[0003] In order to improve efficiency, the existing technology has been improved and a test tube rack has been designed. A test tube rack has multiple test tube holes and can support multiple test tubes at the same time, realizing the function of a test tube rack carrying multiple samples, and these test tube racks can be reused. By placing test tubes on the test tube rack, samples can be transported in rows to the analysis equipment for testing, thereby significantly improving the sample processing efficiency. Correspondingly, some analysis equipment and laboratory automation systems that use test tube racks as circulation units have also appeared on the market. However, despite these advances, the existing technology still has many shortcomings in the sample circulation of intelligent laboratory systems: First of all, for the independent analytical equipment already in the laboratory, due to the limitations of equipment structure, experimental process, regulations or quality system, it is often impossible to adapt and connect them to the laboratory automation system, resulting in these devices can only be used as stand-alone machines and cannot fully realize their potential value.

[0004] Secondly, the specifications of the test tube racks originally equipped with different laboratory equipment are often different. Some equipment's original test tube racks are equipped with eight test tube holes, while others have ten. When test tubes need to be transferred between these different experimental equipment, it is usually necessary to rely on sample transfer devices such as manipulators to repeatedly move the test tubes to the corresponding test tube racks. However, these sample transfer devices generally have the problem of being bulky and occupying too much laboratory area and space, which not only increases the difficulty of laboratory layout, but also further increases the equipment cost.

[0005] In addition, laboratories usually hope that the test tube rack can randomly enter and exit the sample analysis and processing equipment or the corresponding experimental node equipment. After completing the sample processing of the node, the test tube rack should be able to move back to the conveyor line again, transfer to the next node, until the end. However, existing technologies are often unable to achieve such a flexible flow method, which limits the degree of laboratory automation. For example, in some laboratories, due to the complexity of the experimental process, it is necessary to simultaneously transport samples from different flow units, such as microplates, test tubes, and test tube racks. Existing technologies, especially the adaptability of the conveyor line itself, often cannot meet such diverse needs, resulting in interruptions or inefficiencies in the experimental process.

[0006] These problems not only affect the degree of automation and efficiency of the laboratory, but also limit the flexible use of laboratory equipment and space optimization.

[0007] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present inventive concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0008] The purpose of the present invention is to provide a new technical solution to improve or solve the technical problems existing in the prior art as described above.

[0009] The technical solution provided by the present invention is as follows: a sample automatic loading device, comprising an adapter base plate, a sample transfer device, a transfer slide, a docking rack and an experimental carrier, the transfer slide and the docking rack are both arranged on the adapter base plate, the experimental carrier can be docked on the docking rack, and the experimental carrier is located on the conveying path of the transfer slide, and the sample transfer device is used to transfer the sample carrier to the experimental carrier or move it out of the experimental carrier through the transfer slide.

[0010] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: the sample automatic loading device of the present invention can be directly assembled on the workbench of various experimental equipment, so that the flow of test tubes between different equipment no longer needs to rely on sample transfer devices such as manipulators to repeatedly transfer on different test tube racks, which not only ensures that the test tubes can flow smoothly between different experimental equipment, but also can achieve the adaptability and compatibility of the equipment to 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.

[0011] Based on the above technical solution, the present invention can also be improved as follows.

[0012] Furthermore, the induction trigger assembly includes an induction long rod, a connecting block, a telescopic column, a spring II and an induction block, one end of the induction long rod is close to the experimental carrier docking frame, the other end of the induction long rod is connected to the connecting block, one end of the telescopic column is connected to the connecting block, the other end of the telescopic column is installed with the induction block, and the spring II is sleeved on the telescopic column.

[0013] The beneficial effect of adopting the above further solution is that when the experimental carrier is docked on the docking rack, the sensor can be triggered by the induction trigger component, thereby ensuring that the system can accurately identify the docking state of the experimental carrier, and when the experimental carrier is removed from the docking rack, the elastic tension of spring II will restore the induction block to its initial position and separate from the sensor. The induction trigger component triggers the sensor on the laboratory equipment workbench to detect whether the experimental carrier is docked on the docking rack. It can achieve the adaptability and compatibility of the equipment for the full laboratory automation solution without changing the original sensor position and structure of the laboratory equipment, thereby maximizing the use value of the equipment.

[0014] Furthermore, the experimental carrier includes a carrier body, a fulcrum rod, a pressure wheel and a spring I, the carrier body has an installation groove, and the two side walls of the installation groove are provided with a clamping groove; the fulcrum rod is installed on the carrier body through a rotating shaft, the head of the fulcrum rod is provided with a locking tongue, and the tail of the fulcrum rod is rotatably installed with the pressure wheel; one end of the spring I is connected to the carrier body, and the other end of the spring I is connected between the locking tongue of the fulcrum rod and the rotating shaft.

[0015] The beneficial effect of adopting the above further scheme is that the installation groove on the experimental carrier and the card grooves on both sides thereof can cooperate with the guide wings on both sides of the test tube rack, so that the test tube rack can be firmly placed in the installation groove of the experimental carrier. In this way, the test tube rack can not only be supported by the experimental carrier on the workbench, but also can collect information by moving the experimental carrier. The head of the fulcrum rod is provided with a lock tongue. When the test tube rack is docked in the installation groove of the experimental carrier, under the tension of spring I, the lock tongue clamps the test tube rack, and the retaining edges on both sides of the lock tongue form a lock position with the test tube rack installed in the installation groove to prevent the test tube rack from displacement or tipping. When the limit needs to be released, the test tube rack is pushed in the direction close to the docking rack. During the pushing process, the docking rack presses down the pressure wheel, so that the tail of the fulcrum rod is pressed down, thereby causing the head of the fulcrum rod to tilt up, and then the lock tongue is separated from the test tube rack to achieve the cancellation of the limit.

[0016] Furthermore, a meshing tooth row is provided at the bottom of the carrier body.

[0017] Furthermore, the docking frame includes a push rod and a limiter, the limiter can cooperate with the experimental carrier and limit its movement, and the push rod can tilt the locking tongue of the fulcrum rod by pressing the pressure wheel.

[0018] The beneficial effect of adopting the above further scheme is that when the experimental carrier moves close to the docking rack, 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, avoiding the displacement of the experimental carrier due to misoperation or external interference; at the same time, the pushing rod can press the pressure wheel and move the locking tongue of the fulcrum rod to lift up, so that the locking tongue is separated from the test tube rack, and the locking tongue on the experimental carrier is cancelled. Limitation of the test tube rack in the X-axis direction, the test tube rack can move freely in the installation groove.

[0019] Furthermore, the sample transfer device is a bidirectional telescopic device, which includes a base, an active telescopic part, a linked telescopic part, a transmission mechanism, a linkage mechanism and a reversible drive motor. The base, the active telescopic part and the linked telescopic part are arranged in sequence from bottom to top, and the transmission mechanism is arranged between the base and the active telescopic part. The drive motor drives the active telescopic part to perform bidirectional telescopic movement along the length direction through the transmission mechanism, and the linkage mechanism can drive the linked telescopic part to simultaneously telescope along the movement direction of the active telescopic part.

[0020] The beneficial effect of adopting the above further scheme is that the bidirectional telescopic device can be telescoped in two directions. When it is necessary to move a test tube rack or a microplate from the experimental carrier of the laboratory equipment to the movable carrier, or from the movable 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 driving motor, which not only simplifies the structure of the device but also reduces the manufacturing cost.

[0021] A laboratory system comprises laboratory equipment, a mover carrier, a conveyor line and an automatic sample loading device, wherein the conveyor line is arranged at one side of the laboratory equipment, a workbench is provided on the laboratory equipment, the conveyor line and the workbench are connected through the transfer slideway, the mover carrier is located on the conveyor line and can reciprocate along the conveyor line, the laboratory equipment is provided with a workbench, and the adapter base plate is installed on the workbench.

[0022] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: the laboratory system of the present invention can make the equipment compatible with the full laboratory automation solution without changing the original intended use of the laboratory equipment, thereby improving the use value of the equipment. At the same time, it can realize the direct processing of batches of samples at the same time, reducing the cumbersome steps of transferring and replacing test tubes one by one in the past.

[0023] Based on the above technical solution, the present invention can also be improved as follows.

[0024] Furthermore, a driving gear set and a data acquisition device are also provided on the workbench, and an engaging gear row for engaging with the driving gear set is provided at the bottom of the experimental carrier. The driving gear set can pull the experimental carrier out from the docking rack, and the driving gear set can also push the experimental carrier back to its original position. The data acquisition device is used to collect data on the test tubes loaded on the experimental carrier.

[0025] Furthermore, the mover carrier includes a mover body and two groups of side plates relatively arranged on the mover body, and each group of side plates is provided with a slide groove on the opposite side, and at least one end or both ends of the slide groove have a trumpet mouth, and the slide groove protrudes inward relative to the inner wall of the side plate.

[0026] The beneficial effect of adopting the above further solution is that the bell mouth facilitates the smooth sliding of the sample rack, and the slide groove protrudes inwardly 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 sliding along the slide groove between the side plates.

[0027] Furthermore, the two slide grooves have a height difference.

[0028] The beneficial effect of adopting the above further solution is that it can ensure that the test tube rack is loaded in the correct direction to prevent reverse loading.

[0029] Furthermore, it also includes a test tube rack, which is provided with a plurality of test tube hole seats, and guide wings for cooperating with the slide groove are provided at both ends of the test tube rack, and the two guide wings have a height difference. The test tube rack can slide along the slide groove on the movable carrier, and the bottom of the test tube rack does not contact the bottom of the movable carrier, and the bottom of the test tube rack is provided with a groove for placing an identification code.

[0030] The beneficial effect of adopting the above further scheme is that the two guide wings have a height difference, which can ensure that the test tube rack is loaded in the correct direction to prevent reverse loading, and the bottom of the test tube rack does not contact the bottom of the mover carrier. When the test tube rack is installed on the mover 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 mover carrier, thereby avoiding the generation of friction.

[0031] Furthermore, a tower-type buffer device is provided between the conveying line and the laboratory equipment, and the tower-type buffer device is used for temporarily storing the sample tubes to be analyzed.

[0032] The beneficial effect of adopting the above further solution is that the tower cache device can serve as a transfer station for sample test tubes. When the conveyor line delivers the sample test tubes to the tower cache device, the device can quickly receive and properly store these test tubes. At the same time, when the laboratory equipment needs new sample test tubes for analysis, the tower cache device can also respond quickly and deliver the required test tubes to the equipment. Through the tower cache device, the efficiency of sample processing can be improved.

[0033] Furthermore, a reader / writer is provided on the transfer slide, and the reader / writer is used to track the sample carrier transferred from the transfer slide.

[0034] A working method of a laboratory system, the steps comprising: The mover carrier moves along the conveyor line to one side of the laboratory equipment; The experimental carrier is docked on the docking rack; The sample transfer device is started to transfer the sample rack on the movable carrier to the experimental carrier through the transfer slide, or transfer the sample rack on the experimental carrier to the movable carrier; The driving gear moves to a position corresponding to the bottom of one set of experimental carriers, and the driving gear is meshed with the meshing gear row at the bottom of the experimental carrier; The driving gear rotates, and by virtue of its meshing action with the meshing gear row, the experimental carrier is pulled out from the docking frame to a position where information can be collected; Alternatively, the drive gear is reversed to push the test carrier back in the opposite direction to its original position on the docking frame.

[0035] Furthermore, when the experimental carrier is pulled out for sample operation or pushed back to its original position, the data acquisition device collects information on the samples on the experimental carrier.

[0036] The working method of the above-mentioned laboratory system is adopted to improve the automation and efficiency of sample processing and analysis. This method realizes the smooth transfer of the sample rack from the conveyor line to the experimental rack, as well as the positioning and movement of the experimental rack between the docking rack and the information collection position by controlling the coordinated actions of components such as the actuator rack, the experimental rack, the two-way telescopic device, and the driving gear. The data acquisition equipment can collect information on the samples on the experimental rack in real time, ensuring the accuracy and timeliness of the sample analysis. The working method of the present invention not only greatly reduces the steps and time of manual operation and reduces labor costs, but also significantly improves the stability and reliability of sample processing. Through the automated workflow, it effectively avoids the risks of sample damage or loss caused by improper manual operation, thereby ensuring the quality of sample analysis. In addition, the method can also adapt to experiments of different specifications and types to meet a variety of sample analysis needs. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, these terms should not be understood as restrictive interpretations of the content of this application.

[0041] The principles and features of the present invention are described below in conjunction with examples. The examples are only used to explain the present invention and are not used to limit the scope of the present invention.

[0042] Embodiment 1: like Figure 1 - Fig.16 As shown, a laboratory system includes laboratory equipment 300, a moving sub-carrier 400, a conveyor line 500, an adapting base plate 600, an experimental carrier 200, a sample transfer device, a transfer slide 610 and a docking rack 620, wherein the moving sub-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 adapting base plate 600, the experimental carrier 200, the transfer slide 610 and the docking rack 620 are all installed on the workbench 310, the adapting base plate 600 is provided with a receiving area and an operating area, and the transfer The slideway 610 is located in the receiving area, and the two ends of the transfer slideway 610 extend to the conveying line 500 and the operating area respectively. One or more experimental carriers 200 are arranged in the operating area; the experimental carrier 200 can be docked on the docking rack 620, and the experimental carrier 200 is located on the conveying path of the transfer slideway 610. The sample transfer device can transfer the test tube rack 800 on the conveying line 500 to the experimental carrier 200 through the transfer slideway 610, and the sample transfer device can also transfer the test tube rack 800 on the experimental carrier 200 back to the conveying line 500 through the transfer slideway 610. A baffle is provided on the side of the experimental carrier 200 away from the transfer slideway 610 to prevent the test tube rack 800 from tilting when being pulled out or pushed in.

[0043] In addition, in this embodiment: like Figure 1 and Figure 6 As shown, the workbench 310 is also provided with a driving gear set 320 and a data acquisition device 330, and the bottom of the experimental carrier 200 is provided with a meshing gear row 211 for meshing with the driving gear set 320, and the driving gear set 320 can pull the experimental carrier 200 out of the docking rack 620, and the driving gear set 320 can also push the experimental carrier 200 back to its original position. When the experimental carrier 200 is pulled out, the data acquisition device 330 can be used to collect information. In addition, the user can also directly load the test tube rack 800 onto the experimental carrier 200 from the pulled-out position, or take the test tube rack 800 out of the experimental carrier 200. If the docking rack 620 has an empty docking position, 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 with the limitation that the experimental carrier 200 can only be moved in one direction on the existing laboratory equipment workbench, the present invention not only supports the function of taking 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.

[0044] The driving gear set 320 includes two driving gears and a moving mechanism, and the moving mechanism can drive the two driving gears and the data acquisition device 330 to move along the X-axis direction on the workbench 310 .

[0045] Docking rack 620: Figure 7 and Figure 8 As shown, the docking frame 620 is provided with a plurality of docking positions, each of which is provided with a push rod 621 and a stopper. In this embodiment, the stopper is a stopper card 622, which can be inserted into the experimental carrier 200 and limit its movement. More specifically, the stopper card 622 is provided with an arc-shaped protrusion 623, and the experimental carrier 200 is provided with 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 limit the movement of the experimental carrier 200. The push rod 621 can move the U-shaped lock tongue 222 of the experimental carrier 200 by pressing the pressure wheel 221 at the end of the fulcrum rod 220. Of course, the docking frame 620 can also be provided with a docking position, and the number of the docking positions is adapted to the loading quantity of the experimental carrier 200, and the number can be matched according to the size and use requirements of the equipment.

[0046] In another embodiment, Fig.15 and Fig.16As shown, the limiter adopts a ball-shaped top screw 624, and the experimental carrier 200 is provided with a top screw groove 625 that cooperates with the ball-shaped top screw 624. When the experimental carrier 200 is docked on the docking frame, the ball-shaped top screw 624 abuts against the top screw groove 625, thereby limiting the movement of the experimental carrier 200 along the Y-axis direction.

[0047] Experimental carrier 200: Fig. 9 - Fig.13 As shown, it includes a carrier body 210, a fulcrum rod 220, a pressure wheel 221 and a spring I 223. The carrier body 210 is provided with a meshing tooth row 211 at the bottom, and the carrier body 210 has a mounting groove 212. The two side walls of the mounting groove 212 are provided with a clamping groove 213. The fulcrum rod 220 is installed on the carrier body 210 through a rotating shaft. The head of the fulcrum rod 220 is provided with a U-shaped locking tongue 222. Of course, the locking tongue can also be L-shaped or C-shaped as long as the limit requirements are met. The tail of the fulcrum rod 220 is rotatably installed with the pressure wheel 221. One end of the spring I 223 is connected to the carrier 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.

[0048] The U-shaped locking tongue 222 has ribs on both sides, and the width of the U-shaped locking tongue 222 matches 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 clamp the test tube rack 800. At this time, the ribs on both sides of the U-shaped locking tongue 222 form a locking position with the test tube rack 800 installed in the installation groove 212, which can prevent the test tube rack 800 from being displaced or tipped over when the experimental carrier 200 moves along the Y-axis direction. On the contrary, if Figure 8 As shown, when the experimental carrier 200 docks at the docking rack 620, the push rod 621 on the docking rack 620 pushes the pressure wheel 221, so that the tail of the fulcrum rod 220 is pressed down, so that the head of the fulcrum rod 220 is tilted, so that the U-shaped lock tongue 222 is separated from the test tube rack 800, the limit is cancelled, and the test tube rack 800 can move freely along the X-axis direction on the experimental carrier 200. At the same time, the limiter cooperates with the carrier body 210 to prevent the carrier body 210 from moving along the Y-axis direction.

[0049] Induction trigger component 700: Figure 7 and Figure 8As shown, the induction trigger component 700 is arranged on the workbench 310. When the experimental carrier 200 is docked on the docking rack 620, the experimental carrier 200 can trigger the sensor on the workbench 310 through the induction trigger component 700, thereby being able to detect whether the experimental carrier 200 is docked in place on the docking rack 620. The induction trigger assembly 700 includes an induction long rod 710, a connecting block 720, a telescopic column 730, a spring II 740 and an induction block 750. The induction long rod 710 is slidably installed under the adapting base plate 600. One end of the induction long rod 710 is close to the docking frame 620, and the other end of the induction long rod 710 is connected to the connecting block 720. One end of the telescopic column 730 is connected to the connecting block 720. The induction block 750 is installed at the other end of the telescopic column 730. The spring II 740 is sleeved on the telescopic column 730, and the two ends of the spring II 740 are respectively abutted against the connecting block 720 and the adapting base plate 600.

[0050] When the experimental carrier 200 docks at the docking rack 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 installed on the telescopic column 730 to approach the sensor on the workbench 310. Once the sensing block 750 contacts the sensor on the workbench 310, the sensor will immediately send a signal to the control system. After receiving the signal, the control system can accurately determine that the experimental carrier 200 has docked at the docking position. The experimental carrier 200 continues to move toward the docking rack 620, continues to push the sensing rod 710 to move, the connecting block 720 compresses the spring II 740, and the sensing block 750 is in close contact with the sensor. When the experimental carrier 200 is detached from the docking frame 620, the spring II 740 will push the connecting block 720 to move in the opposite direction under the action of the restoring force, thereby driving the sensing long rod 710 and the telescopic column 730 to move in the opposite direction, and the sensing block 750 will be separated from the sensor. At this time, the sensor will send a signal to the control system again, and after receiving this signal, the control system can accurately determine that there is no experimental carrier 200 docked at the docking position.

[0051] Mover carrier 400: Fig.17 and Fig.18As shown, it includes a movable body 410 and two groups of side plates 420 relatively arranged on the movable body 410, the movable body 410 is provided with a lower support plate, and a limiting groove can be set on the lower support plate for transporting a microplate, the microplate is an existing sample carrier, the lower support plate is located between the two groups of the side plates 420, and a slide groove 430 is provided on the opposite side of each group of the side plates 420, and the two slide grooves 430 have a height difference, and at least one end or both ends of the slide groove 430 have a flared mouth to facilitate the smooth sliding of the sample rack, and the slide groove 430 protrudes inwardly relative to the inner wall of the side plate 420 to prevent the test tube rack 800 from contacting the inner wall of the side plate 420 when sliding along the slide groove 430 between the side plates 420.

[0052] The movable carrier 400 also includes a brake assembly 440 for limiting the test tube rack 800 from sliding down. The brake assembly 440 is arranged at the end of the side plate 420. The brake assembly 440 includes a positioning seat 441, a blocking claw 442 and a magnet. The positioning seat 441 is installed on the side plate 420, and the blocking claw 442 is rotatably installed on the positioning seat 441. The end of the blocking claw 442 has a hook-shaped protrusion. The blocking claw 442 and the positioning seat 441 are respectively installed with opposite-polar magnets on the opposite sides. The blocking claw 442 can be reset by using the magnetic attraction between the magnets. When the test tube rack 800 is slid from one end to the other end on the movable carrier 400, the guide wings 820 on both sides of the test tube rack 800 slide in the slide grooves 430 on both sides of the movable carrier 400. When the test tube rack 800 slides to the end of the movable carrier 400, the hook-shaped protrusion at the end of the blocking claw 442 can block the test tube rack 800, playing a stopping role, thereby preventing the test tube rack 800 from slipping during the movement. When the test tube rack 800 is loaded, the test tube rack 800 will continue to move along the slide groove 430 toward the end of the movable carrier 400, and push the blocking claw 442 open in the process. Since the resistance encountered by the blocking claw 442 at this time exceeds the magnetic attraction of the magnet, the blocking claw 442 can overcome the magnetic attraction and temporarily open, thereby not hindering 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 of the opposite polar magnets.

[0053] In another embodiment, the brake assembly 440 includes a positioning seat 441, a blocking claw 442 and a torsion spring. The positioning seat 441 is installed on the side plate 420, and the blocking claw 442 is rotatably installed on the positioning seat 441 through a rotating shaft. The end of the blocking claw 442 has a hook-shaped protrusion, and the torsion spring is used to provide a reset power. The blocking claw 442 is connected through a rotating shaft and is opened and closed by the torsion spring. When encountering resistance, the blocking claw 442 will overcome the elastic force of the torsion spring and temporarily open, and then reset under the reset action of the torsion spring.

[0054] Test tube rack 800: Fig.14 As shown, the test tube rack 800 is provided with a plurality of test tube holes 810 for placing test tubes, and the two ends of the test tube rack 800 are provided with guide wings 820 for cooperating with the slide groove 430, which are respectively a left guide wing 820 and a right guide wing 820. The two guide wings 820 have a height difference, which can ensure that the test tube rack 800 is loaded in the correct way to prevent reverse loading. The left guide wing 820 and the right guide wing 820 of the test tube rack 800 are respectively matched with the slide grooves 430 on the left and right sides of the movable carrier 400, and the test tube rack 800 can slide on the movable carrier 400 along the slide grooves 430. The distance between the left chute 430 and the lower support plate at the bottom of the mover carrier 400 is greater than the dimension between the left guide wing 820 and the bottom of the test tube rack 800. Similarly, the distance between the right chute 430 and the lower support plate is greater than the dimension between the right guide wing 820 and the bottom of the test tube rack 800. When the test tube rack 800 slides along the chute 430 between the mover carriers 400, the test tube rack 800 can maintain a non-contact state with the lower support plate at the bottom of the mover carrier 400, that is, when the test tube rack is mounted on the mover carrier, the test tube rack is in a suspended state, avoiding the friction force generated by the direct contact between the bottom of the test tube rack 800 and the lower support plate of the mover carrier 400. When the test tube rack is mounted on a transfer slide or an experimental carrier, it is also in a suspended state.

[0055] When the experimental carrier 200 is docked on the docking rack 620, and the movable carrier 400 moves to one side of the sample laboratory equipment 300 along the conveying line 500, 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 through the transfer slide 610. Similarly, the sample carrier on the experimental carrier 200 can also be moved to the movable carrier 400 through the transfer slide 610. A reader is also provided on the transfer slide 610. On the basis of the identification code provided at the bottom of the test tube rack 800, the identification code can be an RFID tag, a bar code or other forms of identifiable marks. The reader can track the test tube rack 800 passing through the transfer slide 610.

[0056] 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 manipulator.

[0057] like Fig.24 - Fig.34 As shown, the bidirectional telescopic device 100 includes a base 101, an active telescopic part 102, a linked telescopic part 103, a transmission mechanism, a linkage mechanism and a reversible drive motor 111. The base 101, the active telescopic part 102 and the linked telescopic part 103 are arranged in sequence from bottom to top, and the transmission mechanism is arranged between the base 101 and the active telescopic part 102. The drive motor 111 drives the active telescopic part 102 to perform bidirectional telescopic movement along the length direction through the transmission mechanism, and the linkage mechanism can drive the linked telescopic part 103 to simultaneously telescope along the movement direction of the active telescopic part 102.

[0058] In addition, 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 driven to rotate by the drive motor 111. The embodiment of the present invention does not limit the transmission connection between the drive motor 111 and the main shaft 105. The drive motor 111 and the main shaft 105 can transmit power through chain drive, belt drive or gear drive. The rack 106 is mounted on the active telescopic member 102 and is consistent with the sliding direction of the active telescopic member 102. The first worm gear mechanism 116 and the second worm gear mechanism 117 are respectively arranged at both ends of the main shaft 105, and through the forward and reverse rotation of the main shaft 105, the power is transmitted to the rack 106, and then the active telescopic member 102 is driven to realize bidirectional telescopic movement through the movement of the rack 106. When the driving 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, and the rack 106 will maintain a transmission relationship with at least one of the two worm gear mechanisms during the movement, so that the active telescopic member 102 can be telescoped along the length direction of the rack 106. In addition to the extended length of the linked telescopic member 103, when the bidirectional telescopic device 100 is extended to the unilateral limit position, its unidirectional total extension length is equal to the sum of the lengths of the active telescopic member 102, the linked telescopic member 103 and the base 101 minus the length of the overlapping portion between the active telescopic member 102 and the linked telescopic member 103, and the length of the overlapping portion between the active telescopic member 102 and the linked telescopic member 103, and the active telescopic member 102 and the base 101 designed for increased support. Therefore, by designing a smaller overlapping portion 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 forward and reverse, ensuring that the active telescopic member 102 can perform bidirectional telescopic movement along a preset direction, which not only improves the flexibility and practicality of the bidirectional telescopic device 100, but also further improves its working efficiency and stability.

[0059] More specifically, in the initial state, the active telescopic member 102 is located directly above the base 101, the linkage telescopic member 103 is opposite to the active telescopic member 102, and the two ends of the rack 106 are respectively matched with the first worm gear mechanism 116 and the second worm gear mechanism 117. When the driving motor 111 drives the main shaft 105 to rotate in the forward direction, in the initial stage, the first worm gear mechanism 116 and the second worm gear mechanism 117 are matched with the rack 106 at the same time, pushing the active telescopic member 102 to move in the direction away from the second worm gear mechanism 117. As the active telescopic member 102 moves, the rack 106 will gradually disengage from the second worm gear mechanism 117, but continue to maintain a matching state with the first worm gear mechanism 116. At this time, the first worm gear mechanism 116 will continue to use its rotational cooperation with the main shaft 105 to transmit power to the rack 106, pushing the active telescopic member 102 to continue to move in the direction away from the second worm gear mechanism 117 until it reaches the set position and stops; when the active telescopic member 102 needs to move in the reverse direction, the drive motor 111 is started to rotate in the reverse direction, and the main shaft 105 will rotate in the reverse direction. At this time, the rack 106 and the first worm gear mechanism 116 are still in a coordinated state, and the first worm gear mechanism 116 will reversely push the active telescopic member 102 to move in the direction close to the second worm gear mechanism 117. As the active telescopic member 102 moves in the reverse direction, the active telescopic member 102 returns to the initial state. At this time, the first worm gear mechanism 116 and the second worm gear mechanism 117 are coordinated with the rack 106 at the same time, and then the rack 106 gradually disengages from the first worm gear mechanism 116, and maintains a coordinated state with the second worm gear mechanism 117. Subsequently, the second worm gear mechanism 117 transmits power to the rack 106 by rotating with the main shaft 105, and the movement of the rack 106 drives the active telescopic member 102 to move away from the first worm gear mechanism 116. Therefore, by controlling the rotation direction of the drive motor 111, the bidirectional telescopic movement of the active telescopic member 102 can be achieved.

[0060] The linkage mechanism is responsible for driving the linkage telescopic member 103 to synchronously extend and retract along the moving direction of the active telescopic member 102. The linkage mechanism includes a first transmission belt 107 and a second transmission belt 108. Fig.29 As shown, one end of the first transmission belt 107 is fixed to the left side of the base 101, and is connected to the left side of the linkage telescopic member 103 after passing around the first pulley 109 installed at the right end of the active telescopic member 102; Fig.30 As shown, one end of the second transmission belt 108 is fixed to the right side of the base 101, passes around the second pulley 110 installed on the left side of the linkage telescopic member 103, and is connected to the right side of the linkage telescopic member 103; Fig.31As shown in FIG. 1 , 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, so that the first transmission belt 107 drives the linkage telescopic member 103 to move to the right synchronously. Fig.32 As shown, the second transmission belt 108 is dragged by the linkage telescopic member 103 and also extends to the right synchronously; Fig.34 As shown in FIG. 1 , 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, so that the second transmission belt 108 drives the linkage telescopic member 103 to move to the left synchronously. Fig.33 As shown, the first transmission belt 107 also stretches to the left synchronously under the dragging of the linked telescopic member 103. Through the linkage mechanism, the linked telescopic member 103 can maintain the same movement direction as the active telescopic member 102 to achieve synchronous telescopic.

[0061] A loading lever 104 is provided on one or both sides of the linkage telescopic member 103, and the lever can push the test tube rack 800 to move, thereby facilitating the loading and unloading of test tubes. When the loading lever 104 is provided on both sides of the linkage telescopic member 103, the test tube rack can be moved by one side, and the microplate can be moved by the other side.

[0062] The working method of loading test tubes using the laboratory system is as follows: First, a plurality of the experimental carriers 200 are docked on the docking rack 620. When the experimental carrier 200 is successfully docked at the docking position of the docking rack 620, the corresponding sensing component will be triggered, and the sensing component can activate the sensor on the workbench 310. After the sensor receives the signal, it will send a signal to the control system. After the control system receives this signal, it can accurately determine that the experimental carrier 200 has been docked at the docking position. The number of the experimental carriers 200 can be set according to the maximum loading requirement of the test tube rack, and this number will vary with the size of the adapter. On the other hand, the number of experimental carriers can also be equal to or greater than the maximum number of test tube racks that can be carried on the mover carrier.

[0063] Then, the driving motor 111 of the bidirectional telescopic device 100 is started to rotate the main shaft 105, and the active telescopic member 102 moves toward the conveyor line through the transmission of the worm gear mechanism and the rack 106. At the same time, the linkage mechanism drives the linkage telescopic member 103 to synchronously extend toward the conveyor line. 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 are arranged across the two sides of the conveyor line, and the driving motor 111 stops to wait for the arrival of the mover carrier 400.

[0064] 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 loads 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 the test tube rack is located between the loading levers 104; Next, the driving motor 111 of the bidirectional telescopic device 100 is started to rotate in the opposite direction, and the active telescopic member 102 is pushed to move to the side 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 toward the laboratory equipment 300 until it reaches the installation slot 212 of the experimental carrier 200, and the driving motor 111 stops working; In the information collection stage, when the driving gear moves to the bottom of one group of experimental carriers 200, the driving gear meshes with the meshing gear row 211 at the bottom of the experimental carrier 200, and the driving gear rotates to pull the experimental carrier 200 out of the docking rack 620 along the X-axis direction. Subsequently, the driving gear reverses and pushes 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 reader, scanner or camera) completes information collection, and the system verifies and enters the transmitted sample information. Subsequently, the laboratory equipment 300 begins to perform pipetting, that is, to draw the liquid in the test tube to other carriers for analysis.

[0065] The driving gear can pull the experimental carrier 200 from the first row or the last row to move along the X-axis to the information collection area for scanning / photographing, or can preferentially select a test tube rack 800 for scanning / photographing. For example, after the test tubes on the first experimental carrier 200 are scanned, the test carrier returns to the operation area, and the pipetting channel of the laboratory equipment 300 begins to aspirate samples from the test tubes on the first experimental carrier to other carriers of the equipment for testing. At the same time, the second experimental carrier 200 is pulled out, and scanning, returning and aspirating are started, and so on, scanning and aspirating can be performed simultaneously to improve analysis efficiency.

[0066] When 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 started again, the shaft 105 rotates, and the active telescopic member 102 is pushed to move to one side of the conveyor line through the worm gear mechanism and the rack 106. At the same time, the linkage mechanism drives the linkage telescopic member 103 to move synchronously to one side of the conveyor line, and the loading lever 104 clamps the test tube rack 800 to move to one side of the conveyor line until it is transported back to the movable sub-carrier 400 of the conveyor line. At this time, after the drive motor 111 stops working, the movable sub-carrier 400 will move the test tube rack 800 along the conveyor line to the next inspection station. The bidirectional telescopic device 100 waits for the arrival of the next movable sub-carrier 400.

[0067] The transfer slide 610 can be provided on one or both sides of the bidirectional telescopic device 100. When the loading lever 104 is provided on both sides of the linkage telescopic member 103, the sample carrier can be transferred along the transfer slide 610 on any side through the bidirectional telescopic device 100. For example, the transfer slide 610 on one side can be used to transfer the test microplate, and the transfer slide 610 on the other side can be used to transfer the test tube rack 800. The bidirectional telescopic device 100 can transfer the sample carrier through the transfer channels on both sides simultaneously or separately. In this way, the laboratory system has the ability to transport microplates and test tube racks 800 at the same time, further improving the experimental efficiency.

[0068] Embodiment 2: Different from the first embodiment, a tower cache device 900 is further provided between the conveying line 500 and the laboratory equipment 300 . The tower cache device 900 is used to temporarily store sample tubes to be analyzed. In this embodiment, the bidirectional telescopic device 100 is installed on the tower cache device 900 .

[0069] More specifically, if Fig.19 - Fig.23 As shown, the tower cache 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 installed on the tower 901, the output shaft of the electric cylinder 904 is rotatably connected to the lead screw of the linear lifting assembly 905, the back plate 903 is installed on the inner wall of the tower 901 through the linear lifting assembly 905 in a manner that allows it to be lifted, and a plurality of trays 902 are spaced from top to bottom on the back plate 903.

[0070] In addition, the transfer slide 610 includes a front transfer slide 913 and a rear transfer slide 914, which are respectively installed on both sides of the tower 901, and the front transfer slide 913 extends to the operation area of ​​the laboratory equipment 300, and the rear transfer slide 914 is docked with 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 slide 913 and the rear transfer slide 914, the tray 902 close to the outlet on the side of the laboratory equipment 300 can be docked with the front transfer slide 913, so that the sample carrier can move in or out from the front outlet; the tray 902 close to the outlet on the side of the conveyor line 500 can be docked with the rear transfer slide 914, so that the sample carrier can move in or out from the rear outlet. The front transfer slide 913 is also provided with a reader / writer, which is used to track the sample carriers, such as the test tube rack 800, transferred from the front transfer slide 913. On the basis of the identification code at the bottom of the transferred test tube rack 800, when these sample carriers are transferred to the tray 902 of the tower buffer device 900 through the front transfer slide 913, the reader / writer equipped on the tray 902 can automatically read the identification code at the bottom of the test tube rack 800. Not only does it realize the real-time tracking and monitoring of the test tube rack 800, but it is also conducive to the management of the inventory test tube rack 800. Through the automatic reading and recording of the reader / writer, the system can update the location, quantity and status of the test tube rack 800 in real time, providing a more intelligent and reliable storage and tracking solution for laboratories, medical institutions, scientific research institutions and other places.

[0071] In this embodiment, the bidirectional telescopic device 100 is installed on the tower 901 through 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 telescopic shaft of the lifting motor 113 can drive the bidirectional telescopic device 100 to rise and fall.

[0072] The tower cache device 900 also includes a blocking mechanism, which is linked to the lifting mechanism 112, and 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, wherein the first guide rail 916 and the second guide rail 920 are arranged in parallel on the tower 901; the transmission gear set 918 is rotatably installed on the tower 901; the first slide 917 is slidably installed on the first guide rail 916 and is connected to the base 101 of the bidirectional telescopic device, the first slide 917 can be linked to the bidirectional telescopic device 100, and an active rack is arranged on the first slide 917; the second slide 919 is slidably installed on the second guide rail 920, and a passive rack is arranged on the second slide 919; wherein 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 thereto to move upward along the first guide rail 916, and through the engagement of the active rack and the transmission gear set 918, 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; on the contrary, when the base 101 descends under the drive of the lifting mechanism 112, it will drive the first slide 917 connected thereto to move downward along the first guide rail 916, and through the engagement of the active rack and the transmission gear set 918, further drive the second slide 919 to descend along the second guide rail 920. As the second slide 919 descends, it moves 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 can protect the sample carrier during storage, prevent the sample carrier from falling off the tray 902 and being damaged, and improve the safety and stability of the storage device.

[0073] A working method of the laboratory system, comprising the steps of: The mover carrier 400 moves along the conveyor line 500 to one side of the laboratory equipment 300; The experimental carrier 200 is docked on the docking rack 620; The sample transfer device transfers the sample rack on the movable carrier 400 to the experimental carrier 200 through the transfer slide 610, or transfers the sample rack on the experimental carrier 200 to the movable carrier 400; The driving gear moves to a position corresponding to the bottom of one set of experimental carriers 200, and the driving gear is meshed with the meshing gear row 211 at the bottom of the experimental carrier 200; The driving gear rotates, and by virtue of its meshing action with the meshing gear row 211, the test carrier 200 is pulled out from the docking rack 620; Reversing the drive gear can push the test carrier 200 back to its original position on the docking rack 620 in the opposite direction.

[0074] When the experimental carrier 200 is pulled out for sample operation or pushed back to its original position, the data acquisition device 330 acquires information about the samples on the experimental carrier 200 .

[0075] The detailed working method of using the tower buffer device 900 of the present invention to store the test tube rack 800 is as follows: First, start the driving motor 111 of the bidirectional telescopic device 100, and drive the main shaft 105 to rotate through the driving motor 111, and then push the active telescopic part 102 to move to the side close to the conveyor line through the worm gear mechanism and the rack 106. At the same time, the linkage mechanism drives the linkage telescopic part 103 and the active telescopic part 102 to extend and retract synchronously. When the linkage telescopic part 103 moves to the conveyor line, the driving motor 111 stops working, and the loading lever 104 is straddled on both sides of the conveyor line to wait for the arrival of the movable carrier 400 carrying the test tube rack 800 on the conveyor line.

[0076] Next, the drive cylinder of the tower cache device 900 is started, and the linear lifting assembly 905 drives the tray 902 on the back plate 903 to move up and down. After an empty tray 902 on which the test tube rack 800 is parked moves to the same height as the front transfer slide 913 and the rear transfer slide 914, the drive cylinder stops working.

[0077] Subsequently, 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 is loaded with the test tube rack 800 and moves on the conveyor line 500, and the movable carrier 400 stops when it moves along the conveyor line to between the loading levers 104. At this time, the driving motor 111 of the two-way telescopic device 100 is started again, and the main shaft 105 is driven to rotate in the opposite direction by the driving motor 111, and then the active telescopic member 102 is pushed to move to the side away from the conveyor line through the worm gear mechanism and the rack 106, and the loading lever 104 clamps the test tube rack 800 to be transported and moves toward the tray 902. After moving to the tray 902 through the front transfer slide 913 or the rear transfer slide 914, the driving motor 111 stops.

[0078] When the loading lever 104 of the bidirectional telescopic device 100 clamps the sample carrier 800 and stops at any position, such as 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 other positions without moving the batch of sample carriers 800, it is necessary to adjust the height of the loading lever 104 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, and the lifting motor 113 is started to raise the bidirectional telescopic device 100 to a certain height. When the linkage telescopic member 103 and the loading lever 104 thereon move up to a height higher than the test tube on the test tube rack 800, the lifting motor 113 stops. At the same time, the blocking mechanism will be linked, and the second slide seat 919 will rise and block at the end of the tray 902 to prevent the test tube rack 800 from falling off.

[0079] After that, the driving motor 111 of the two-way telescopic device 100 is started again, and the main shaft 105 is driven to rotate by the driving motor 111, and the active telescopic member 102 moves to the side close to the conveyor line, and the linkage mechanism drives the linkage telescopic member 103 to be synchronously extended and retracted with the active telescopic member 102. When the linkage telescopic member 103 moves to the side of the test tube rack 800 carrying device on the conveyor line, the driving motor 111 stops working. The lifting motor 113 is started to lower the two-way telescopic device 100 to a low position, and the loading lever 104 is again set across the two sides of the conveyor line, waiting for the arrival of the next movable carrier 400 carrying the test tube rack 800.

[0080] 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 principle of the present invention should be included in the protection scope of the present invention.
