Description

Technical Field

[0001] This utility model relates to a tower-type transfer device, belonging to the field of experimental equipment technology. Background Technology

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

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

[0004] When a set of samples needs to be transferred between multiple devices for different analyses, the varying processing efficiencies of each device often result in situations where a more efficient device has to wait for a less efficient device after completing its task. This not only reduces overall processing efficiency but also wastes time and resources. Furthermore, for applications requiring the processing of large numbers of samples or long-term experiments, existing sample analysis systems often cannot meet the sample storage requirements.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present invention, and therefore may include information that does not constitute prior art. Utility Model Content

[0006] The purpose of this utility model is to provide a new technical solution to improve or solve the technical problems existing in the prior art as described above.

[0007] The technical solution provided by this utility model is as follows: A tower-type transfer device includes a tower, a tray, a back plate and a linear lifting module. The back plate is installed on the tower in a lifting manner through the linear lifting module, and multiple trays are spaced apart on the back plate from top to bottom.

[0008] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: First, by setting the tower-type transfer device on the side of the equipment with low processing efficiency, the equipment with high processing efficiency can temporarily transfer the product (i.e., the sample carrier and the sample on it) to the tower-type transfer device after completing its analysis task, thus not affecting the subsequent analysis process; Second, the tower-type transfer device of this utility model has multiple trays, which not only saves floor space, but also increases storage capacity through vertical stacking, and can store a large number of sample carriers, which is very important for occasions that require processing a large number of samples or conducting long-term experiments; In addition, the lifting function of the trays facilitates the storage and retrieval of sample carriers, and sample carriers from any layer can be obtained according to actual needs, improving the flexibility and efficiency of sample transfer.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the tray includes a lower support plate and two sets of side plates, which are disposed opposite to each other on the lower support plate. Each set of side plates has a groove on one side facing each other for guiding the movement of other components, and the groove protrudes inward relative to the inner wall of the side plate.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the groove protrudes inward relative to the inner wall of the side plate, which is used to prevent the sample carrier from contacting the inner wall of the side plate when it slides along the groove between the side plates.

[0012] Furthermore, the two grooves have a height difference in the height direction.

[0013] The advantage of adopting the above-mentioned further solution is that it can ensure that the sample carrier is loaded in the correct manner and prevent it from being loaded backwards.

[0014] Furthermore, at least one of the grooves has a flared opening at one or both ends.

[0015] The advantage of adopting the above-mentioned further solution is that it facilitates the smooth sliding of items into or out of the chute.

[0016] Furthermore, it also includes a sensor assembly, which includes at least one sensor and a plurality of auxiliary elements disposed on the back panel, the auxiliary elements being used to cooperate with the sensor, the number of the auxiliary elements being adapted to the number of the trays, and each of the trays being provided with a corresponding auxiliary element.

[0017] The beneficial effect of adopting the above-mentioned further solution is that when the tray moves to the preset position as the back plate rises and falls, the auxiliary element corresponding to the tray can trigger the sensor, thereby realizing the detection and monitoring of the tray position.

[0018] Furthermore, it also includes a front loading position slide and / or a rear loading position slide, which are respectively installed on both sides of the tower, and a certain pallet on the back plate can move up and down to dock with the front loading position slide and / or the rear loading position slide.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the products on the pallet can be moved in or out through the front loading position slide and / or the rear loading position slide. Specifically, the front outlet of the pallet can be connected to the front loading position slide so that the products can be moved in or out from the front outlet; the rear outlet of the pallet can be connected to the rear loading position slide so that the products can be moved in or out from the rear outlet.

[0020] Furthermore, multiple layers of front loading position slides and / or rear loading position slides are provided on the tower.

[0021] Furthermore, the front loading chute and / or the rear loading chute are also provided with a reader / writer for tracking products transferred from the front loading chute and / or the rear loading chute.

[0022] The beneficial effects of adopting the above-mentioned further solution are that, through the automatic reading function of the reader, real-time tracking and monitoring of transferred products can be achieved, which not only improves the accuracy and efficiency of product tracking, but also greatly reduces the error rate and cost of manual operation. In addition, the data collected by the reader can enable precise management of inventory products.

[0023] Furthermore, it also includes a bidirectional telescopic device, which is installed inside the tower and located on one side of the tray. The bidirectional telescopic device includes a base, an active telescopic component, a linked telescopic component, a transmission mechanism, a linkage mechanism, and a forward and reverse drive motor. The base, active telescopic component, and linked telescopic component are arranged sequentially from bottom to top. The base is installed on the tower, and the transmission mechanism is located between the base and the active telescopic component. The drive motor drives the active telescopic component to perform bidirectional telescopic movement along the length direction through the transmission mechanism. The linkage mechanism can drive the linked telescopic component to telescopically extend and retract simultaneously along the movement direction of the active telescopic component. During the telescopic process, the active telescopic component can move the product into or out of the tray.

[0024] The beneficial effects of adopting the above-mentioned further solution are as follows: First, the bidirectional telescopic device of this utility model can realize the bidirectional telescopic movement of the entire bidirectional telescopic device through a single drive motor, which simplifies the structure of the device and reduces manufacturing costs; Second, the bidirectional telescopic device can not only maintain its initial position and rise and fall within the tower-type transfer device, but also extend and retract in two directions, which can push the sample rack out of the tray or push the sample rack into the tray from the outside, thus improving the flexibility of use.

[0025] Furthermore, the bidirectional telescopic device is installed on the tower via a lifting mechanism, which can drive the bidirectional telescopic device to rise and fall.

[0026] Furthermore, it also includes a blocking mechanism, which includes a first guide rail, a first slide block, a transmission gear set, a second slide block, and a second guide rail. The first guide rail and the second guide rail are arranged in parallel. The first slide block is slidably mounted on the first guide rail and is linked with the lifting mechanism. The second slide block is slidably mounted on the second guide rail. The first slide block and the second slide block mesh with the transmission gear set through their respective racks.

[0027] The beneficial effect of adopting the above-mentioned further solution is that the blocking mechanism can prevent products from falling off the tray and being damaged, thereby protecting the products during storage and improving the safety and stability of the transfer device.

[0028] Furthermore, it also includes a manual screw jack, which includes a brake, a gear transmission assembly, a lead screw, and a nut. The brake and the lead screw are connected via the gear transmission assembly. The nut is threadedly connected to the lead screw. The back plate is fixedly connected to the nut. The nut can drive the back plate to move up and down along the lead screw.

[0029] The beneficial effect of adopting the above-mentioned further solution is that, in the event of a power outage or failure of other automatic lifting systems, the manual screw jack can ensure that the tower transfer device continues to work. By manually operating the brake, users can achieve smooth lifting and lowering of products such as the back plate, tray, and sample carriers carried on it, providing users with a convenient lifting method.

[0054] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and do not imply any priority in order or any specific technical meaning. Furthermore, the concepts of "connection" and "linkage" mentioned in this application, unless otherwise specified, are considered to include both direct connection (linkage) and indirect connection (linkage).

[0055] When interpreting the description of this application, it should be clarified that terms such as "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating directions or positional relationships, are based on the perspective and layout shown in the accompanying drawings. They are intended to facilitate explanation and simplify the description process, and are not absolute limitations on the actual location, construction method, or operating mode of the described device or element. Therefore, these terms should not be construed as restrictive interpretations of the content of this application.

[0056] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0057] like Figure 1 - Figure 8 As shown, the technical solution provided by this utility model is as follows: A tower-type transfer device includes a tower 901, a tray 902, a back plate 903, and a linear lifting module 905. The back plate 903 is mounted on the tower 901 in a lifting manner through the linear lifting module 905. Multiple trays 902 are spaced apart from top to bottom on the back plate 903. Multiple sets of screw holes can be provided on the back plate 903 for adjusting the distance between the upper and lower parts of the trays 902.

[0058] In addition, in this embodiment,

[0059] The linear lifting module 905 is used to drive the back plate and its tray 902 to move up and down. The tower-type transfer device also includes a drive cylinder 904, which can be a pneumatic cylinder, hydraulic cylinder, or electric cylinder, etc. The drive cylinder 904 is mounted on the tower 901 and is used to provide lifting power to the linear lifting module. In addition, the embodiments of this utility model do not limit the structure of the linear lifting module 905. The linear lifting module 905 can adopt a screw and nut mechanism, and linear lifting can be achieved by rotating the screw and moving the nut; at the same time, other types of lifting mechanisms can also be used, such as pneumatic or hydraulic drive systems, electric linear modules, etc., as long as they can meet the performance requirements of the tower-type transfer device, they should be within the protection scope of this utility model.

[0060] The tray 902 includes a lower support plate 909 and two sets of side plates 908. The two sets of side plates 908 are disposed opposite each other on the lower support plate 909. Each set of side plates 908 has a groove 907 on its opposite side for guiding the movement of other components. The groove 907 protrudes inward relative to the inner wall of the side plate 908. When a sample carrier 800 is loaded onto the tray, the sample carrier 800 slides along the groove 907 between the side plates 908 without contacting the inner wall of the side plate 908, and the bottom of the sample carrier 800 also does not contact the lower support plate 909, preventing friction between the tray 902 and the sample carrier 800. The two grooves 907 have a height difference in the vertical direction, ensuring that the sample carrier 800 is loaded correctly and preventing reverse loading. At least one or both ends of the groove 907 have a flared opening to facilitate the smooth sliding of the sample carrier 800 into or out of the groove 907. Figure 20 As shown, the sample carrier 800 is provided with multiple test tube holders 810 for placing test tubes. The two ends of the sample carrier 800 are provided with guide wings 820 for cooperating with the slide grooves 907, namely the left guide wing 820 and the right guide wing 820. The two guide wings 820 have a height difference. The left guide wing 820 and the right guide wing 820 of the sample carrier 800 respectively cooperate with the slide grooves 907 on the left and right sides of the tray 902, and the sample carrier 800 can slide along the slide grooves 907 on the tray 902. Furthermore, the distance from the left-side slide groove 907 to the bottom of the tray 902 is greater than the distance from the left-side guide wing 820 to the bottom of the sample carrier 800. Similarly, the distance from the right-side slide groove 907 to the bottom of the tray 902 is greater than the distance from the right-side guide wing 820 to the bottom of the sample carrier 800. When the sample carrier 800 slides along the slide groove 907 between the trays 902, the sample carrier 800 can remain in a non-contact state with the bottom of the tray 902, avoiding friction caused by direct contact between the bottom of the sample carrier 800 and the bottom of the tray 902.

[0061] The tower-type transfer device also includes a sensor assembly comprising at least one sensor 911 and multiple auxiliary elements 912 disposed on a back plate 903. The number of auxiliary elements 912 matches the number of trays 902, ensuring that each tray 902 has a corresponding auxiliary element 912 on one side. The auxiliary element 912 is used to cooperate with the sensor 911 to convert the position state of the corresponding tray into a signal that the sensor can recognize.

[0062] In this embodiment, the sensor 911 is a light sensor 911, and the auxiliary element 912 is a light-shielding plate 912. The sensor assembly includes two light sensors 911, which are fixed on the tower 901. When the light-shielding plate 912 corresponding to a tray 902 on a certain layer is simultaneously inserted into the photosensitive slots of the two light sensors 911, the system can detect that the tray 902 has reached a preset position, thereby achieving accurate detection and monitoring of the position of the tray 902. In addition to light sensors and light-shielding plates, the sensor 911 can also use other types of sensors, such as infrared sensors, ultrasonic sensors, laser sensors, etc. Correspondingly, the auxiliary element 912 also needs to be selected and designed according to the type of sensor. For example, if an infrared sensor is used, the auxiliary element may be a reflective surface that can reflect infrared light; if an ultrasonic sensor is used, the auxiliary element may be an object that can generate or reflect ultrasonic waves.

[0063] Furthermore, the tower-type transfer device also includes a front loading position slide 913 and a rear loading position slide 914, which are respectively installed on both sides of the tower 901. When a tray 902 on the back plate 903 moves up and down to the same height as the front loading position slide 913 and the rear loading position slide 914, the tray 902 can dock with the front loading position slide 913 and the rear loading position slide 914. Specifically, the front outlet of the tray 902 can dock with the front loading position slide 913 to allow products to be moved in or out from the front outlet; the rear outlet of the tray 902 can dock with the rear loading position slide 914 to allow products to be moved in or out from the rear outlet. Of course, depending on actual needs, the tower-type transfer device can also have separate loading position trays 902 at the front or rear of the tray 902, as long as such a configuration can meet the actual needs of loading and unloading operations. Multiple layers of front loading position slide rails 913 and / or rear loading position slide rails 914 can also be provided on the tower 901. For example, front loading position slide rails 913 and rear loading position slide rails 914 can be provided on each layer of the tower 901, or front loading position slide rails 913 can be provided on each layer of the tower 901, or rear loading position slide rails 914 can be provided on each layer of the tower 901.

[0064] When pallet 902 moves to the same height as the front loading slide 913 or the rear loading slide 914 and docks, the auxiliary element 912 corresponding to pallet 902 will activate sensor 911, enabling the system to accurately identify that pallet 902 has reached the loading / unloading position, thereby ensuring the monitoring of the position of pallet 902.

[0065] A reader / writer is also provided on the front loading chute 913 for tracking products transferred from it. Alternatively, the reader / writer can be installed on the rear loading tray 902. Based on the identification code affixed to the bottom of the transferred product (e.g., sample carrier 800), which can be an RFID tag, barcode, or other form of identifiable marker, when these products are transferred to the tray 902 of the tower transfer device via the front loading chute 913 or the rear loading chute 914, the reader / writer on the tray 902 can automatically read or write the identification code on the bottom of the sample carrier 800. This not only enables real-time tracking and monitoring of the sample carrier 800 but also facilitates the management of the inventory of sample carriers 800. Through the automatic reading and recording of the reader / writer, the system can update the location, quantity, and status of the sample carriers 800 in real time, providing a more intelligent and reliable storage and tracking solution for laboratories, medical institutions, and research units.

[0066] The tower-type transfer device also includes a bidirectional telescopic device 100, which is installed inside the tower 901 and located on one side of the tray 902. The bidirectional telescopic device 100 includes a base 101, an active telescopic component 102, a linked telescopic component 103, a transmission mechanism, a linkage mechanism, and a reversible drive motor 111. The base 101, active telescopic component 102, and linked telescopic component 103 are arranged sequentially from bottom to top. The base 101 is mounted on the tower 901 via a lifting mechanism 112. A transmission mechanism is disposed between the base 101 and the active telescopic member 102. The drive motor 111 drives the active telescopic member 102 to perform bidirectional telescopic movement along its length direction through the transmission mechanism. The linkage mechanism can drive the linkage telescopic member 103 to simultaneously telescopically move along the movement direction of the active telescopic member 102. The linkage telescopic member 103 is provided with a loading lever 104. During the telescopic process, the active telescopic member 102 can move products into or out of the tray 902 through the loading lever 104. The bidirectional telescopic device 100 can telescopic in two directions, allowing the sample rack to be pushed out of the tray 902 or pushed into the tray 902 from the outside.

[0067] The bidirectional telescopic device 100 is installed on the tower 901 via a lifting mechanism 112. Specifically, the lifting mechanism 112 includes a lifting motor 113, a lifting plate 114, and a base plate 115. The cylinder of the lifting motor 113 is fixed on the base plate 115, and the base plate 115 is fixed on the tower 901. The telescopic shaft of the lifting motor 113 is connected to the lifting plate 114. The base 101 of the bidirectional telescopic device 100 is installed above the lifting plate 114. The extension and retraction of the telescopic shaft of the lifting motor 113 can drive the bidirectional telescopic device 100 to rise and fall.

[0068] More specifically, such as Figure 9-19 As shown, the transmission mechanism of the bidirectional telescopic device 100 includes a main shaft 105, a first worm gear mechanism 116, a second worm gear mechanism 117, and a rack 106. The main shaft 105 is rotatably mounted on the base 101 and is driven to rotate by the drive motor 111. This embodiment of the invention does not limit the transmission connection method 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 maintains the same sliding direction as the active telescopic member 102. The first worm gear mechanism 116 and the second worm gear mechanism 117 are respectively disposed at both ends of the main shaft 105, and transmit power to the rack 106 through forward and reverse rotation with the main shaft 105. The movement of the rack 106 then drives the active telescopic member 102 to achieve bidirectional telescopic movement. When the drive motor 111 starts and drives the main shaft 105 to rotate, the first worm gear mechanism 116 and the second worm gear mechanism 117 will operate synchronously. During the movement, the rack 106 will maintain a transmission relationship with at least one of the two worm gear mechanisms, so that the active telescopic member 102 can extend and retract along the length direction of the rack 106. In addition to the extension length of the linkage telescopic member 103, when the bidirectional telescopic device 100 is extended to the limit position on one side, its total unidirectional extension length is equal to the sum of the lengths of the active telescopic member 102, the linkage telescopic member 103 and the base 101, minus the length of the overlapping part designed for the added support between the active telescopic member 102 and the linkage telescopic member 103, and between the active telescopic member 102 and the base 101. Therefore, by designing a smaller overlapping part size, the telescopic range of the bidirectional telescopic device 100 can be effectively expanded. In addition, the drive motor 111 can drive the main shaft 105 to rotate in both directions, ensuring that the active telescopic member 102 can perform bidirectional telescopic movement along the preset direction. This not only improves the flexibility and practicality of the bidirectional telescopic device 100, but also further improves its working efficiency and stability.

[0069] More specifically, in the initial state, the active telescopic member 102 is located directly above the base 101, and the linkage telescopic member 103 is vertically opposite to the active telescopic member 102. The two ends of the rack 106 are respectively engaged with the first worm gear mechanism 116 and the second worm gear mechanism 117. When the drive motor 111 drives the main shaft 105 to rotate forward, in the initial stage, the first worm gear mechanism 116 and the second worm gear mechanism 117 simultaneously engage with the rack 106, pushing the active telescopic member 102 to move away from the second worm gear mechanism 117. As the active telescopic member 102 moves, the rack 106 gradually disengages from the second worm gear mechanism 117, but continues to maintain engagement with the first worm gear mechanism 116. At this time, the first worm gear mechanism 116 continues to transmit power to the rack 106 through its rotational engagement with the main shaft 105, pushing the active telescopic member 102 to continue moving away from the second worm gear mechanism 117 until it reaches a set position and stops. When the active telescopic member 102 needs to move in the opposite direction, the drive motor 111 is activated to rotate in the opposite direction, and the main shaft 105 will rotate in the opposite direction. At this time, the rack 106 and the first worm gear mechanism 116 are still engaged, and the first worm gear mechanism 116 will push the active telescopic member 102 to move closer to the second worm gear mechanism 117. As the active telescopic member 102 moves in the opposite direction, it returns to its initial state. At this time, the first worm gear mechanism 116 and the second worm gear mechanism 117 simultaneously engage with the rack 106. Then, the rack 106 gradually disengages from the first worm gear mechanism 116 while maintaining engagement with the second worm gear mechanism 117. Subsequently, the second worm gear mechanism 117, through its rotational engagement with the main shaft 105, transmits power to the rack 106. The movement of the rack 106 then drives the active telescopic member 102 to move away from the first worm gear mechanism 116. Therefore, by controlling the rotational direction of the drive motor 111, the bidirectional telescopic movement of the active telescopic member 102 can be achieved.

[0070] The linkage mechanism is responsible for driving the linkage telescopic member 103 to extend and retract synchronously along the movement direction of the active telescopic member 102. The linkage mechanism includes a first transmission belt 107 and a second transmission belt 108, such as... Figure 14 As shown, one end of the first transmission belt 107 is fixed to the left side of the base 101, and after passing around the first pulley 109 installed at the right end of the active telescopic member 102, it is connected to the left side of the linkage telescopic member 103; as shown Figure 15 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; as shown Figure 16As shown, 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, thereby causing the first transmission belt 107 to drive the linkage telescopic member 103 to move to the right synchronously. Simultaneously, as... Figure 17 As shown, the second transmission belt 108 is also pulled to the right synchronously by the linkage telescopic component 103; as Figure 19 As shown, 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, thereby causing the second transmission belt 108 to drive the linkage telescopic member 103 to move to the left synchronously. Simultaneously, as... Figure 18 As shown, the first transmission belt 107 also extends synchronously to the left under the drag of the linkage telescopic member 103. Through the linkage mechanism, the linkage telescopic member 103 can maintain the same direction of movement as the active telescopic member 102, achieving synchronous extension and retraction.

[0071] The linkage telescopic component 103 is provided with a loading lever 104 on one or both sides. The lever can push the sample carrier 800 to move, thereby facilitating the loading and unloading of the test tube.

[0072] The tower-type transfer device also includes a blocking mechanism, which is linked to the lifting mechanism 112. The blocking mechanism can be installed at both the entrance and exit of the tray 902. The blocking mechanism includes a first guide rail 916, a first slide 917, a transmission gear set 918, a second slide 919, and a second guide rail 920. The first guide rail 916 and the second guide rail 920 are arranged parallel to each other on the tower 901. The transmission gear set 918 is rotatably mounted on the tower 901. The first slide 917 is slidably mounted on the first guide rail 916 and connected to the base 101 of the bidirectional telescopic device 100. The first slide 917 can be linked with the bidirectional telescopic device 100 and is provided with an active rack. The second slide 919 is slidably mounted on the second guide rail 920 and is provided with a passive rack. The first slide 917 and the second slide 919 are respectively meshed with the transmission gear set 918 through the active rack and the passive rack. When the bidirectional telescopic device 100 rises under the drive of the lifting mechanism 112, it will drive the first slide 917 connected to it to move upward along the first guide rail 916. Through the meshing of the active rack and the transmission gear set 918, it will further drive the second slide 919 to rise along the second guide rail 920. As the second slide 919 rises, its upper part will block the end of the tray 902, thereby effectively preventing the products stored on the tray 902 from falling off. Conversely, when the bidirectional telescopic device 100 descends under the drive of the lifting mechanism 112, it will drive the first slide 917 connected to it to move downward along the first guide rail 916. Through the meshing of the active rack and the transmission gear set 918, it will further drive the second slide 919 to descend along the second guide rail 920. As the second slide 919 descends, it will move away from the end of the tray 902. At this time, if necessary, products can be taken off or placed on the tray 902.

[0073] The tower-type transfer device also includes a manual screw jack, which comprises a brake 921, a gear transmission assembly 922, and a screw-nut mechanism. The screw-nut mechanism includes a screw 923 and a nut 924. The brake 921 and the screw 923 are connected via the gear transmission assembly 922. The nut 924 is threadedly connected to the screw 923. The back plate 903 is fixedly connected to the nut 924. The nut 924 can drive the back plate 903 to move up and down along the screw 923. The gear transmission assembly 922 includes a worm and a turbine. The brake 921 is mounted on the tower 901. The worm is mounted on the output shaft of the brake 921. The turbine is mounted on the end of the screw 923 and meshes with the worm. The nut 924 is fixed to the back plate 903 and can drive the back plate 903 to move up and down along the screw 923. In the event of a power outage, the user can manually drive the worm gear to rotate by operating the brake 921. This rotation, via the worm wheel and lead screw 923, enables the smooth lifting and lowering of the back plate 903, tray 902, and the sample carrier 800 it supports. Of course, the gear transmission assembly 922 can be configured and used in different ways depending on specific needs and scenarios during design and application.

[0074] The working method of storing sample carrier 800 using the tower-type transfer device of this utility model is as follows:

[0075] First, the drive motor 111 of the bidirectional telescopic device 100 is started, which drives the main shaft 105 to rotate. Then, through the worm gear mechanism and rack 106, the active telescopic member 102 is pushed to move towards the side closer to the conveyor line. At the same time, the linkage mechanism drives the linkage telescopic member 103 to extend and retract synchronously with the active telescopic member 102. When the linkage telescopic member 103 moves to the conveyor line, the drive motor 111 stops working, and the loading lever 104 is straddling both sides of the conveyor line to wait for the arrival of the sample carrier 800 carried by the moving carrier frame on the conveyor line.

[0076] At the same time, the drive cylinder of the tower transfer device is activated, and the linear lifting module 905 drives the tray 902 on the back plate 903 to move up and down. After one of the empty trays 902 of the sample carrier 800 moves to the same height position as the front loading position slide 913 and the rear loading position slide 914, the drive cylinder stops working.

[0077] Subsequently, the test tube to be tested is placed in the test tube holder 810 of the sample carrier 800. The moving carrier, carrying the sample carrier 800, moves along the conveyor line and stops when it reaches the loading lever 104. At this time, the drive motor 111 of the bidirectional telescopic device 100 is restarted. The drive motor 111 drives the main shaft 105 to rotate in the opposite direction, which in turn pushes the active telescopic member 102 to move away from the conveyor line through the worm gear mechanism and rack 106. The loading lever 104 clamps the sample carrier 800 to be transported and moves towards the tray 902. After moving onto the tray 902 through the front loading slide 913 or the rear loading slide 914, the drive motor 111 stops.

[0078] When the loading lever 104 of the bidirectional telescopic device 100 holds the sample carrier 800 and stops at any position, such as on the front transfer slide 913, the rear transfer slide 914, or the tray 902, if it is necessary to move the loading lever 104 from both sides of the sample carrier 800 to another position without moving the batch of sample carriers 800, the height of the loading lever 104 needs to be adjusted first. Since the base 101 is installed above the lifting plate 114, the entire bidirectional telescopic device 100 will rise and fall with the movement of the lifting plate 114. Start the lifting motor 113 to raise the bidirectional telescopic device 100 to a certain height. When the linkage telescopic component 103 and the loading lever 104 on it move up to a height higher than the test tubes on the sample carrier 800, the lifting motor 113 stops. At the same time, the blocking mechanism will be linked, the second slide 919 will rise and block the end of the tray 902 to prevent the sample carrier 800 from falling off. Figure 5 and Figure 6 .

[0079] Then, the drive motor 111 of the bidirectional telescopic device 100 is restarted. The drive motor 111 drives the main shaft 105 to rotate, and the active telescopic component 102 moves to the side closer to the conveyor line. The linkage mechanism drives the linkage telescopic component 103 to extend and retract synchronously with the active telescopic component 102. When the linkage telescopic component 103 moves to the side of the sample carrier 800 carrying device on the conveyor line, the drive motor 111 stops working. The lifting motor 113 is started to lower the bidirectional telescopic device 100 to the low position, and the loading lever 104 is once again straddling both sides of the conveyor line, waiting for the arrival of the next moving carrier carrying the sample carrier 800.

[0080] The tower-type transfer device of this invention can be installed between the analytical equipment and the conveyor line. After completing its analytical task, the equipment with high processing efficiency can temporarily transfer the sample carrier 800 and the samples on it to the tower-type transfer device via the conveyor line, thus not affecting the subsequent analysis process. The tower-type transfer device of this invention has multiple trays 902, which not only saves floor space but also increases storage capacity through vertical stacking, enabling the storage of a large number of sample carriers 800. This is very important for occasions that require processing a large number of samples or conducting long-term experiments. The lifting function of the trays 902 facilitates the storage and retrieval of sample carriers 800, allowing the acquisition of sample carriers 800 from any layer according to actual needs, thus improving the flexibility and efficiency of sample transfer.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
