Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of sample automatic loading device and laboratory system, belong to experimental equipment technical field. BACKGROUND

[0002] In intelligent sample inspection system, sample circulation and analysis are the key link in laboratory automation process. The traditional laboratory system mainly relies on single tube mode as the basic unit of sample circulation, i.e. 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 is circulated 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 achieves automation to some extent, its efficiency is limited when dealing with a large number of samples.

[0003] To improve efficiency, the prior art has been improved, and a test tube rack has been designed. One test tube rack has multiple test tube hole seats, which can support multiple test tubes at the same time, realizing the function of one test tube rack carrying multiple samples, and these test tube racks can be reused repeatedly. By placing the test tube on the test tube rack, the sample can be transported in rows to the analysis equipment for testing, significantly improving the sample processing efficiency. Some analysis equipment and laboratory automation systems on the market use test tube racks as the circulation unit. However, despite these advances, the existing technology still has many shortcomings in the sample circulation of intelligent laboratory systems:

[0004] Firstly, for the existing independent analysis equipment in the laboratory, due to the limitations of equipment structure, experimental process, regulations or quality system, it is often impossible to adapt to compatibility to access the laboratory automation system, resulting in these devices can only be used as a single machine, and cannot fully realize their potential value.

[0005] Secondly, the specifications of the original test tube racks of different laboratory equipment often differ. Some devices come with eight test tube seats, while others have ten. When the test tubes need to be circulated between these different experimental equipment, it is usually necessary to rely on mechanical hands and other sample transfer devices to repeatedly move the test tubes to the corresponding test tube racks. However, these sample transfer devices generally have the problem of large size, occupying too much laboratory area and space, which not only increases the difficulty of laboratory layout, but also further increases the cost of equipment.

[0006] In addition, laboratories often hope that the tube rack can randomly enter and exit the sample analysis processing equipment or the corresponding experimental node equipment, and after completing the sample processing of the node, the tube rack should be able to move back to the conveying line again, go to the next node, and so on until the end. However, the prior art often cannot realize such flexible flow mode, which limits the degree of automation of the laboratory. For example, in some laboratories, due to the complexity of the experimental process, samples of different flow units such as microwell plates, test tubes and test tube racks need to be transported at the same time, and the existing technology, especially the adaptation ability of the conveying line itself, often cannot meet such diversified needs, resulting in interruption or low efficiency of the experimental process.

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

[0008] It should be noted that the above information disclosed in the background section is only used to understand the background of the present application, and therefore, it can contain information that does not constitute prior art. Content of the application

The induction triggering assembly triggers the inductor on the laboratory equipment workbench to detect whether the experimental carrier is parked in place on the parking stand.

In this way, the test tube rack can not only be supported by the experimental carrier on the workbench, but also be moved for information collection. The head of the fulcrum rod is provided with a lock tongue, when the test tube rack is parked in the mounting groove of the experimental carrier, the lock tongue is clamped on the test tube rack under the tension of the spring I, the blocking edges on the two sides of the lock tongue form a locking position with the test tube rack installed in the mounting groove, preventing the test tube rack from being displaced or falling down, when it is necessary to cancel the limiting, the test tube carrier is pushed towards the parking stand, in the process of pushing, the parking stand presses the pressure wheel, so that the tail of the fulcrum rod is pressed down, thereby causing the head of the fulcrum rod to be raised, and then the lock tongue is separated from the test tube rack, realizing the cancellation of the limiting.

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

[0018] Further, the parking rack comprises a pushing rod and a position limiter, the position limiter is capable of cooperating with the experimental carrier and limiting the movement of the experimental carrier, and the pushing rod is capable of lifting the locking tongue of the fulcrum lever by pressing the pressing wheel.

[0019] The beneficial effect of the above further scheme is that when the experimental carrier moves close to the parking rack, the position limiter forms a Y-axis direction limit with the experimental carrier, ensuring the firm fixation of the experimental carrier on the parking position, avoiding the displacement of the experimental carrier caused by misoperation or external force interference; at the same time, the pushing rod can press the pressing wheel, and the locking tongue of the fulcrum lever is lifted to separate the locking tongue from the test tube rack, canceling the X-axis direction limit of the test tube rack on the experimental carrier by the locking tongue on the experimental carrier, and the test tube rack can move freely in the installation slot.

[0027] The beneficial effect of the above further scheme is that the flared opening facilitates the smooth sliding of the sample rack, the sliding groove is inwardly protruded relative to the inner wall of the side plate, and is used for preventing the test tube rack from contacting the inner wall of the side plate when sliding along the sliding groove between the side plates.

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

A blocking strip is arranged on the side of the experimental carrier 200 away from the transfer slide 610, which can prevent the test tube rack 800 from being skewed when being pulled out or pushed in.

[0093] In addition, in the present embodiment:

[0094] As shown in Figure 1 and Figure 6 ​As shown, the workbench 310 is further provided with a driving gear set 320 and a data acquisition device 330, the experimental carrier 200 is provided with a meshing gear row 211 at the bottom for engaging with the driving gear set 320, the driving gear set 320 can pull the experimental carrier 200 out of the parking rack 620, and the driving gear set 320 can also push the experimental carrier 200 back to the 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 from the experimental carrier 200. If the parking rack 620 has an empty parking position, the operator can also move the experimental carrier 200 loaded with the test tube rack 800 along the Y-axis direction to the idle parking position for loading. Compared with the existing laboratory equipment workbench which can only move the experimental carrier 200 in one direction, the utility model not only supports the function of taking and placing the experimental carrier 200 in the Y-axis direction, but also has the function of conveying the experimental carrier 200 in the X-axis direction.

[0095] 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.

[0096] Parking rack 620: as shown in Figure 7 and Figure 8 As shown, the parking rack 620 is provided with a plurality of parking positions, and each parking position is provided with a push rod 621 and a stopper. In this embodiment, the stopper is a limiting card 622, which can be inserted on the experimental carrier 200 and limit its movement. More specifically, the limiting card 622 is provided with an arc-shaped protrusion 623, and the experimental carrier 200 is provided with an arc-shaped groove 214 matched 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, and the push rod 621 can push 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 parking rack 620 can also be provided with one parking position, and the number of parking positions is matched with the loading number of the experimental carrier 200, and the number can be matched according to the size and use requirements of the equipment.

[0097] In another embodiment, as shown in Figure 15 and Figure 16As shown, the stopper adopts a wave bead top pin 624, and the experimental rack 200 is provided with a top pin groove 625 matched with the wave bead top pin 624. When the experimental rack 200 is parked on the parking rack, the wave bead top pin 624 abuts against the top pin groove 625, thereby being able to limit the movement of the experimental rack 200 along the Y-axis direction.

[0098] Experimental rack 200: as Figure 9 - Figure 13 As shown, it comprises a rack body 210, a fulcrum rod 220, a compression wheel 221 and a spring I 223. The bottom of the rack body 210 is provided with a meshing tooth row 211. The rack body 210 has a mounting groove 212, and the two side walls of the mounting groove 212 are provided with clamping grooves 213. The fulcrum rod 220 is installed on the rack body 210 through a rotating shaft. The head of the fulcrum rod 220 is provided with a U-shaped lock tongue 222. Of course, the lock tongue can also be L-shaped or C-shaped, as long as it meets the limiting requirements. The tail of the fulcrum rod 220 is rotatably installed with the compression wheel 221. One end of the spring I 223 is connected with the rack body 210, and the other end of the spring I 223 is connected between the lock tongue and the rotating shaft of the fulcrum rod 220.

[0099] The U-shaped lock tongue 222 has a stopping edge on both sides, and the width of the U-shaped lock tongue 222 is matched with the width of the test tube rack 800. When the experimental rack 200 is separated from the parking rack 620, the tension of the spring I 223 will pull the fulcrum rod 220, so that the head of the fulcrum rod 220 is pressed down, and then the U-shaped lock tongue 222 clamps the test tube rack 800. At this time, the stopping edges on both sides of the U-shaped lock tongue 222 form a locking position with the test tube rack 800 installed in the mounting groove 212, and when the experimental rack 200 moves along the Y-axis direction, the displacement or overturning of the test tube rack 800 can be prevented. Conversely, as shown, Figure 8 When the experimental rack 200 parks on the parking rack 620, the push rod 621 on the parking rack 620 will push the compression wheel 221, so that the tail of the fulcrum rod 220 is pressed down, thereby making the head of the fulcrum rod 220 rise up, so that the U-shaped lock tongue 222 is separated from the test tube rack 800, the limiting position is cancelled, and the test tube rack 800 can move freely along the X-axis direction on the experimental rack 200. At the same time, the stopper cooperates with the rack body 210 to prevent the rack body 210 from moving along the Y-axis direction.

[0100] Induction trigger assembly 700: as Figure 7 and Figure 8As shown, the induction trigger assembly 700 is arranged on the workbench 310, when the experimental carrier 200 is parked on the parking rack 620, the experimental carrier 200 can trigger the inductor on the workbench 310 through the induction trigger assembly 700, so as to detect whether the experimental carrier 200 is parked in place on the parking rack 620. The induction trigger assembly 700 comprises an induction long rod 710, a connecting block 720, an extension column 730, a spring II 740 and an induction block 750, the induction long rod 710 is slidingly installed below the adaptive bottom plate 600, one end of the induction long rod 710 is close to the parking rack 620, the other end of the induction long rod 710 is connected with the connecting block 720, one end of the extension column 730 is connected with the connecting block 720, the induction block 750 is installed on the other end of the extension column 730, the spring II 740 is sleeved on the extension column 730, and the two ends of the spring II 740 are respectively abutted with the connecting block 720 and the adaptive bottom plate 600.

[0101] When the experimental carrier 200 parks on the parking rack 620, the experimental carrier 200 will touch the end of the induction long rod 710 and push the induction long rod 710 to move, the induction long rod 710 drives the extension column 730 and the induction block 750 installed on the extension column 730 to move together to the inductor on the workbench 310, once the induction block 750 contacts with the inductor on the workbench 310, the inductor will immediately send a signal to the control system, after the control system receives the signal, it can accurately judge that the experimental carrier 200 has been parked on the parking position. The experimental carrier 200 continues to move to the parking rack 620 and continues to push the induction long rod 710 to move, the connecting block 720 will compress the spring II 740, and the induction block 750 is in close contact with the inductor. When the experimental carrier 200 is separated from the parking rack 620, the spring II 740 will push the connecting block 720 to move reversely under the action of restoring force, and then drive the induction long rod 710 and the extension column 730 to move reversely, and the induction block 750 will be separated from the inductor. At this time, the inductor will send a signal to the control system again, and after the control system receives the signal, it can accurately judge that the experimental carrier 200 has not been parked on the parking position.

[0102] Mover carrier 400: as Figure 17 and Figure 18As shown, the mover carrier 400 comprises a mover body 410 and two groups of side plates 420 arranged oppositely on the mover body 410, the mover body 410 is provided with a lower supporting plate, a limiting groove can be arranged on the lower supporting plate for supporting a microplate, the microplate is an existing sample carrier, the lower supporting plate is located between the two groups of side plates 420, each group of side plates 420 is provided with a sliding groove 430 on the side facing each other, the two sliding grooves 430 have a height difference, at least one end of the sliding groove 430 or both ends have a trumpet mouth, which facilitates the smooth sliding of the sample rack, the sliding groove 430 is protruded inwardly relative to the inner wall of the side plate 420, which is used to prevent the test tube rack 800 from contacting the inner wall of the side plate 420 when sliding along the sliding groove 430 between the side plates 420.

[0103] The mover carrier 400 further comprises a brake assembly 440 for limiting the sliding of the test tube rack 800, the brake assembly 440 is arranged at the end of the side plate 420, the brake assembly 440 comprises a positioning seat 441, a blocking claw 442 and a magnet, the positioning seat 441 is mounted on the side plate 420, the blocking claw 442 is rotatably mounted on the positioning seat 441, the end of the blocking claw 442 has a hook-shaped protrusion, the opposite sides of the blocking claw 442 and the positioning seat 441 are respectively provided with a magnet of different poles, the blocking claw 442 can be reset by using the magnetic attraction force between the magnets. When the test tube rack 800 is slid from one end to the other end on the mover carrier 400, the guide wings 820 on both sides of the test tube rack 800 slide in the sliding grooves 430 on both sides of the mover carrier 400, when the test tube rack 800 slides to the end of the mover carrier 400, the hook-shaped protrusion at the end of the blocking claw 442 can block the test tube rack 800, which plays a role of stop and prevents the test tube rack 800 from sliding during movement; when it is necessary to unload the test tube rack 800, the test tube rack 800 will continue to move along the sliding groove 430 to the end of the mover carrier 400, and in the process, the blocking claw 442 will be pushed open, 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 temporarily open against the magnetic attraction force, so as not to hinder the continuous movement of the test tube rack 800, when the test tube rack 800 moves away, the blocking claw 442 can be reset under the mutual attraction of the magnets of different poles.

[0104] 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.

[0105] Test tube rack 800: such as Figure 14 As shown, 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 it from being installed backwards. 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.

[0106] When the experimental rack 200 is parked on the parking rack 620, and the mover rack 400 moves to one side of the sample laboratory equipment 300 along the conveying line 500, the transfer chute 610, the mover rack 400 and the experimental rack 200 are in communication, and through the sample transfer device, the sample carrier on the mover rack 400 can be transferred to the experimental rack 200 through the transfer chute 610, and likewise, the sample carrier on the experimental rack 200 can also be moved to the mover rack 400 through the transfer chute 610. The transfer chute 610 is also provided with a reader / writer, and on the basis that the tube rack 800 is provided with an identification code, which can be an RFID tag, a bar code or other forms of identifiable markers, the reader / writer can track the tube rack 800 passing through the transfer chute 610.

[0107] In this embodiment, the sample transfer device adopts a bidirectional telescopic device 100, and the sample transfer device can also adopt other forms, such as a truss transfer device or a mechanical hand, etc.

[0108] As shown in Figure 24 Figure 34 The bidirectional telescopic device 100 includes a base 101, a main telescopic part 102, a linkage telescopic part 103, a transmission mechanism, a linkage mechanism and a reversible drive motor 111, the base 101, the main telescopic part 102 and the linkage telescopic part 103 are arranged in sequence from bottom to top, the transmission mechanism is arranged between the base 101 and the main telescopic part 102, the drive motor 111 drives the main telescopic part 102 to perform bidirectional telescopic movement along the length direction through the transmission mechanism, and the linkage mechanism can drive the linkage telescopic part 103 to perform telescopic movement along the movement direction of the main telescopic part 102 at the same time.

[0109] ​In addition, the transmission mechanism of the bidirectional telescopic device 100 comprises 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 installed on the base 101 and is driven to rotate by the driving motor 111; the driving connection mode between the driving motor 111 and the main shaft 105 is not limited in the embodiment of the utility model, and the driving motor 111 and the main shaft 105 can transmit power through chain transmission, belt transmission or gear transmission. The rack 106 is installed on the active telescopic part 102 and is consistent with the sliding direction of the active telescopic part 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 transmit power to the rack 106 through forward and reverse rotation cooperation with the main shaft 105, and then drive the active telescopic part 102 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 keep transmission relationship with at least one of the two worm gear mechanisms in the movement process, so that the active telescopic part 102 can be telescopic along the length direction of the rack 106, and the total one-way extension length of the bidirectional telescopic device 100 when extending to the single-side limit position is equal to the sum of the lengths of the active telescopic part 102, the linkage telescopic part 103 and the base 101 minus the length of the overlapping part between the active telescopic part 102 and the linkage telescopic part 103 and between the active telescopic part 102 and the base 101 due to the increase of support, therefore, by designing the smaller size of the overlapping part, the telescopic range of the bidirectional telescopic device 100 can be effectively expanded. In addition, the driving motor 111 can drive the forward and reverse rotation of the main shaft 105, which ensures that the active telescopic part 102 can be bidirectional telescopic along the preset direction, not only improves the flexibility and practicability of the bidirectional telescopic device 100, but also further improves the working efficiency and stability.

[0110] 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 forward, 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, and the active telescopic member 102 is pushed to move away from the second worm gear mechanism 117. With the movement of the active telescopic member 102, the rack 106 gradually disengages from the second worm gear mechanism 117, but continues to be matched 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 the rotation of the main shaft 105, and the active telescopic member 102 continues to move away from the second worm gear mechanism 117 until it stops at the set position; when the active telescopic member 102 needs to move reversely, the driving motor 111 is started to rotate reversely, and the main shaft 105 rotates reversely. At this time, the rack 106 is still matched with the first worm gear mechanism 116, and the first worm gear mechanism 116 reversely pushes the active telescopic member 102 to move towards the second worm gear mechanism 117. With the reverse movement of the active telescopic member 102, the active telescopic member 102 returns to the initial state, and at this time, the first worm gear mechanism 116 and the second worm gear mechanism 117 are matched with the rack 106 at the same time. Then, the rack 106 gradually disengages from the first worm gear mechanism 116 and is matched with the second worm gear mechanism 117. Subsequently, the second worm gear mechanism 117 transmits power to the rack 106 through the rotation of 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 driving motor 111, the bidirectional telescopic movement of the active telescopic member 102 can be realized.

[0111] The linkage mechanism is responsible for driving the linkage telescopic member 103 to move 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 on the left side of the base 101, and is connected to the left side of the linkage telescopic member 103 by passing around the first belt pulley 109 installed on the right end of the active telescopic member 102. Figure 30 , one end of the second transmission belt 108 is fixed on the right side of the base 101, and is connected to the right side of the linkage telescopic member 103 by passing around the second belt pulley 110 installed on the left side of the linkage telescopic member 103. Figure 31As shown, when the active telescopic member 102 moves to the right, the first belt wheel 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, and at the same time, as shown in the figure, the second transmission belt 108 is also dragged by the linkage telescopic member 103 to extend to the right synchronously. Figure 32 As shown, when the active telescopic member 102 moves to the left, the second belt wheel 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, and at the same time, as shown in the figure, the first transmission belt 107 is also dragged by the linkage telescopic member 103 to extend to the left synchronously. Through the linkage mechanism, the linkage telescopic member 103 can keep the same movement direction as the active telescopic member 102, realizing synchronous telescoping. Figure 34 Figure 33 As shown, when the active telescopic member 102 moves to the left, the second belt wheel 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, and at the same time, as shown in the figure, the first transmission belt 107 is also dragged by the linkage telescopic member 103 to extend to the left synchronously. Through the linkage mechanism, the linkage telescopic member 103 can keep the same movement direction as the active telescopic member 102, realizing synchronous telescoping.

[0112] One side or both sides of the linkage telescopic member 103 are provided with loading push rods 104, which can push the test tube rack 800 to move, thereby facilitating the loading and unloading of test tubes. When loading push rods 104 are arranged on both sides of the linkage telescopic member 103, one side can push the test tube rack to move, and the other side can push the microwell plate to move.

[0113] The working method for loading test tubes by using the laboratory system is as follows:

[0114] Firstly, a plurality of experimental carriers 200 are parked on the parking rack 620, and when the experimental carrier 200 successfully parks on the parking position of the parking rack 620, the corresponding sensing assembly is triggered, which can activate the sensor on the workbench 310. After the sensor receives the signal, it sends a signal to the control system, and after the control system receives the signal, it can accurately determine that the experimental carrier 200 has been parked on the parking position. The number of experimental carriers 200 can be set according to the maximum loading demand of the test tube rack, and this number will vary with the size of the adaptive device. On the other hand, the number of experimental carriers can be equal to or greater than the maximum number of test tube racks that can be carried on the mover carrier.

[0115] Then, the driving motor 111 of the bidirectional telescopic device 100 is started, and the main shaft 105 starts to rotate. Through the transmission of the worm gear mechanism and the rack 106, the active telescopic member 102 moves to the conveying line side. At the same time, the linkage mechanism drives the linkage telescopic member 103 to extend to the conveying line side synchronously, and when the linkage telescopic member 103 drives the loading push rod 104 to reach the conveying line, the loading push rods 104 on both sides of the linkage telescopic member 103 are arranged on both sides of the conveying line, and the driving motor 111 stops, waiting for the arrival of the mover carrier 400.

[0116] ​At this time, the test tubes to be detected are placed in the test tube hole seats 810 of the test tube racks 800, and the mover carrier 400 carrying the test tube racks 800 moves on the conveying line 500. When the mover carrier 400 moves to the interface with the transfer chute 610, the movement is stopped, and at this time, the test tube racks are located between the loading levers 104;

[0117] Then, the driving motor 111 of the bidirectional telescopic device 100 is started to rotate reversely, and the main telescopic part 102 is driven to move away from the conveying line through the meshing transmission of the worm and gear mechanism and the rack 106. At this time, the test tube racks 800 clamped by the loading levers 104 move to the laboratory equipment 300, and after reaching the mounting groove 212 of the experimental carrier 200, the driving motor 111 stops working;

[0118] In the information collection stage, when the driving gear moves to the bottom of one of the experimental carriers 200, the driving gear meshes with the meshing teeth row 211 at the bottom of the experimental carrier 200, and the rotation of the driving gear pulls the experimental carrier 200 out of the parking rack 620 along the X-axis direction. Then, the driving gear reverses to push the experimental carrier 200 back to the original position. During the pulling out or pushing back of the experimental carrier 200, the data collection equipment 330 (such as a code scanner, a scanner or a camera) completes information collection, and the system verifies and enters the sample information transmitted. Then, the laboratory equipment 300 starts to perform pipetting processing, i.e. to suck the liquid in the test tube to other carriers for analysis.

[0119] The driving gear can pull the experimental carrier 200 to move along the X-axis to the information collection area for code scanning / photographing from the first row or from the last row, or can preferentially select a test tube rack 800 for code scanning / photographing. For example, after the test tubes on the first experimental carrier 200 are scanned, the experimental carrier is returned to the operation area, and the pipetting channel of the laboratory equipment 300 starts to suck the sample from the test tubes on the first experimental carrier to other carriers of the equipment for detection. At the same time, the second experimental carrier 200 is pulled out and starts to scan the code, return and suck the liquid, and so on. The code scanning and liquid sucking can be performed synchronously to improve the analysis efficiency.

[0120] When the detection is completed, the test tube rack 800 needs to be returned to the conveying line. At this time, the driving motor 111 is started again, the shaft 105 rotates, the main telescopic part 102 is pushed to move to the conveying line side through the worm gear mechanism and the rack 106, at the same time, the linkage mechanism drives the linkage telescopic part 103 to move to the conveying line side synchronously, the loading lever 104 clamps the test tube rack 800 to move to the conveying line side, until it is conveyed back to the mover carrier 400 on the conveying line. At this time, the driving motor 111 stops working, and the mover carrier 400 moves along the conveying line with the test tube rack 800 to the next detection station. The bidirectional telescopic device 100 waits for the arrival of the next mover carrier 400.

[0121] A transfer chute 610 can be arranged on one side or both sides of the bidirectional telescopic device 100. When the loading lever 104 is arranged on both sides of the linkage telescopic part 103, the bidirectional telescopic device 100 can transfer the sample carrier along the transfer chute 610 on either side. For example, one side of the transfer chute 610 can be used to transfer the test microplate, and the other side of the transfer chute 610 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 simultaneously, further improving the efficiency of the experiment.

[0122] Embodiment two:

[0123] Different from embodiment one, a tower type buffer device 900 is further arranged between the conveying line 500 and the laboratory equipment 300, which is used for temporarily storing sample test tubes to be analyzed.

When a certain tray 902 on the backboard 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 close to the side of the laboratory equipment 300 can be connected with the front transfer chute 913, so that the sample carrier is moved in or out of the front outlet; the outlet of the tray 902 close to the side of the conveying line 500 can be connected with the rear transfer chute 914, so that the sample carrier is moved in or out of the rear outlet. The front transfer chute 913 is also provided with a reader / writer, which is used to track the sample carriers such as the tube rack 800 moved from the front transfer chute 913. On the basis that the bottom of the moved tube rack 800 is provided with an identification code, when these sample carriers are moved to the tray 902 of the tower type cache device 900 through the front transfer chute 913, the reader / writer equipped on the tray 902 can automatically read the identification code at the bottom of the tube rack 800. Not only the real-time tracking and monitoring of the tube rack 800 are realized, but also the management of the inventory tube rack 800 is facilitated. Through the automatic reading and recording of the reader / writer, the system can update the information such as the position, quantity and state of the tube rack 800 in real time, and provide a more intelligent and reliable storage and tracking solution for laboratories, medical institutions and scientific research units.

[0126] In the embodiment, the bidirectional telescopic device 100 is installed on the tower 901 through a lifting mechanism 112. Specifically, the lifting mechanism 112 comprises a lifting motor 113, a lifting plate 114 and a base plate 115. The cylinder body of the lifting motor 113 is fixed on the base plate 115, the base plate 115 is fixed on the tower 901, the telescopic shaft of the lifting motor 113 is connected with the lifting plate 114, and the base 101 of the bidirectional telescopic device 100 is installed above the lifting plate 114.

[0127] The tower type cache device 900 further comprises a blocking mechanism which is linked with the lifting mechanism 112, the blocking mechanism comprises a first guide rail 916, a first sliding seat 917, a transmission gear set 918, a second sliding seat 919 and a second guide rail 920, 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 sliding seat 917 is slidably installed on the first guide rail 916 and is connected with the base 101 of the bidirectional telescopic device, the first sliding seat 917 can be linked with the bidirectional telescopic device 100, a driving gear rack is arranged on the first sliding seat 917; the second sliding seat 919 is slidably installed on the second guide rail 920, a driven gear rack is arranged on the second sliding seat 919; wherein the driving gear rack and the driven gear rack are meshed and driven through the transmission gear set 918.

Through the blocking mechanism, the protection of the sample carrier storage process is realized, the sample carrier is prevented from falling off and being damaged from the tray 902, and the safety and stability of the storage device are improved.

[0128] A working method of the laboratory system, comprising the steps of:

[0129] The mover carrier 400 moves along the conveying line 500 to one side of the laboratory equipment 300;

[0130] The experiment carrier 200 is parked on the parking rack 620;

[0131] The sample transfer device transfers the sample rack on the mover carrier 400 to the experiment carrier 200 through the transfer chute 610, or transfers the sample rack on the experiment carrier 200 to the mover carrier 400;

[0132] The drive gear moves to a position corresponding to the bottom of one of the experiment carriers 200, and the drive gear is meshed with the meshing gear row 211 at the bottom of the experiment carrier 200;

[0133] The driving gear is rotated to pull the experimental carrier 200 out of the parking rack 620 by meshing with the gear row 211;

[0134] The driving gear is reversed to push the experimental carrier 200 back to its original position on the parking rack 620 in the opposite direction.

[0135] During the process of pulling out the experimental carrier 200 for sample operation or pushing back to the original position, the data acquisition device 330 collects information on the samples on the experimental carrier 200.

[0136] The detailed working method of the tower type buffer device 900 for storing the test tube rack 800 is as follows:

[0137] Firstly, the driving motor 111 of the bidirectional telescopic device 100 is started, the main shaft 105 is rotated by the driving motor 111, and then the main telescopic part 102 is pushed to move to the side close to the conveying line through the worm gear mechanism and the rack 106, at the same time, the linkage mechanism drives the linkage telescopic part 103 to synchronously telescope with the main telescopic part 102, when the linkage telescopic part 103 moves to the conveying line, the driving motor 111 stops working, and the loading lever 104 is arranged on both sides of the conveying line to wait for the arrival of the moving carrier 400 carrying the test tube rack 800.

[0138] Then, the driving cylinder of the tower type buffer device 900 is started, the straight line lifting assembly 905 drives the back plate 903 and the tray 902 on the back plate 903 to move up and down, after the empty tray 902 for parking the test tube rack 800 moves to the same height position as the front transfer slide 913 and the rear transfer slide 914, the driving cylinder stops working.

[0139] Subsequently, the test tube to be detected is placed in the test tube hole seat 810 of the test tube rack 800, and the moving carrier 400 carrying the test tube rack 800 moves on the conveying line 500, and stops when the moving carrier 400 moves to between the loading levers 104. At this time, the driving motor 111 of the bidirectional telescopic device 100 is started again, the main shaft 105 is reversely rotated by the driving motor 111, and then the main telescopic part 102 is pushed to move to the side away from the conveying line through the worm gear mechanism and the rack 106, the loading lever 104 clamping the test tube rack 800 to be conveyed moves towards the tray 902, and after moving to the tray 902 through the front transfer slide 913 or the rear transfer slide 914, the driving motor 111 stops.

[0140] When the loading lever 104 of the bidirectional telescopic device 100 is clamping the sample carrier 800 at any position, for example, at the front transfer slide 913, the rear transfer slide 914 or the tray 902, if it is needed to move the loading lever 104 from the two sides of the sample carrier 800 to other positions without moving the batch of sample carriers 800, it is needed to adjust the height of the loading lever 104 first. Since the base 101 is installed above the lifting plate 114, the whole bidirectional telescopic device 100 will be lifted along with the movement of the lifting plate 114, the lifting motor 113 is started to lift the bidirectional telescopic device 100 to a certain height, when the linkage telescopic part 103 and the loading lever 104 thereon are moved to a height higher than the test tubes on the test tube rack 800, the lifting motor 113 is stopped. At the same time, the blocking mechanism will be linked, the second sliding seat 919 is lifted and blocked at the end of the tray 902, preventing the test tube rack 800 from falling off.

[0141] Then, the driving motor 111 of the bidirectional telescopic device 100 is started again, the main shaft 105 is rotated by the driving motor 111, the driving telescopic part 102 is moved to the side close to the conveying line, the linkage mechanism drives the linkage telescopic part 103 to synchronously telescope with the driving telescopic part 102, when the linkage telescopic part 103 is moved to the side of the test tube rack 800 bearing device on the conveying line, the driving motor 111 is stopped. The lifting motor 113 is started to lower the bidirectional telescopic device 100 to the low position, the loading lever 104 is crossed on the two sides of the conveying line again, waiting for the next mover carrier 400 carrying the test tube rack 800.

[0142] The above only describes the preferred embodiments of the present application and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
