Description

Technical Field

[0001] The present invention relates to the technical field of material transfer, and in particular to a transport mechanism and a sample processing device. Background Art

[0002] Targeted next-generation sequencing (tNGS) sample pre-processing automation equipment has important applications in the fields of biomedicine and life science research, and has promoted the widespread application and development of targeted next-generation sequencing technology. The tNGS sample pre-processing automation equipment consists of a pre-cup processing module, a high-speed centrifugation module, and a post-cup processing module. Among them, the pre-cup processing module mainly transfers biological samples to centrifuge tubes and adds internal reference bacterial solution. The high-speed centrifugation module mainly separates biological samples into different layers or precipitates for subsequent analysis and processing. The post-cup processing module is mainly used to resuspend, mix, or transfer biological samples after high-speed centrifugation.

[0003] During the processing of the post-cup processing module, it is necessary to use a clamp to clamp the centrifuge tube and transfer it to other locations for subsequent operations. However, when the clamp needs to clamp the centrifuge tube and move it a long distance, the robot arm that drives the clamp to move also needs to be longer. In this way, the driving force required by the robot arm is large, and the energy consumption is large. In addition, the robot arm occupies a large amount of operating space in the post-cup processing module, which has a great impact on the structural layout of the post-cup processing module and seriously wastes the installation space of the post-cup processing module.

[0024] In order to make the purpose, technical scheme and advantages of the present invention more obvious, the exemplary embodiments according to the present invention will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments of the present invention, and it should be understood that the present invention is not limited to the exemplary embodiments described herein. Based on the embodiments of the present invention described in the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the protection scope of the present invention.

[0025] In the following description, a large amount of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only exemplarily illustrates a preferred embodiment of the present invention, and the present invention can be implemented without one or more such details. In addition, in order to avoid confusion with the present invention, some technical features well known in the art are not described in detail.

[0026] In order to fully understand the embodiments of the present invention, detailed structures will be presented in the following description. Obviously, the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. The preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other embodiments.

[0027] In one embodiment of the present invention, a transport mechanism is provided, which can be used in fields such as testing and laboratory research. A transport mechanism according to an embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] like Figure 1 and Figure 2As shown, the transport mechanism includes a driving member 1, a first transmission assembly 2, a second transmission assembly 3 and a clamping assembly 4. The first transmission assembly 2 includes a first rotating member 21 and a first transmission member 22 connected to the first rotating member 21, and the driving member 1 drives the first transmission member 22 to reciprocate along the first direction through the first rotating member 21. The second transmission assembly 3 is arranged on the first transmission member 22, and the second transmission assembly 3 includes a second rotating member 31 and a second transmission member 32 connected to the second rotating member 31, and the second rotating member 31 is connected to the first transmission member 22. The clamping assembly 4 is connected to the second transmission member 32. Among them, the second rotating member 31 and the second transmission member 32 are mutually constructed as follows: when the first transmission member 22 reciprocates along the first direction, the second transmission member 32 generates an interaction force with the second rotating member 31, and the second transmission member 32 causes the clamping assembly 4 to reciprocate along the first direction under the interaction.

[0029] The object to be transported can be placed under the clamping assembly 4, and the first direction can be represented as the movement direction of the clamping assembly 4 toward or away from the object to be transported. For example, when the clamping assembly 4 is arranged in a vertical direction, the first direction can be represented as a vertical direction. Figure 1 As shown, the clamping assembly 4 is arranged along an inclined direction, and the first direction can be expressed as the inclined direction.

[0030] The driving member 1 can be connected to the first rotating member 21 and drive the first rotating member 21 to rotate in a clockwise direction or a counterclockwise direction. The first rotating member 21 can be connected to the first transmission member 22, so as to convert the circumferential rotation of the first rotating member 21 into the linear motion of the first transmission member 22. Specifically, when the first transmission member 22 rotates counterclockwise, it can drive the first transmission member 22 to move in a direction close to the object to be transported. Conversely, when the first transmission member 22 rotates clockwise, it can drive the first transmission member 22 to move in a direction away from the object to be transported.

[0031] The driving member 1 may specifically be a device such as a motor or a cylinder that can drive the first rotating member 21 to rotate, and this application does not make any specific limitation on this.

[0032] The second rotating member 31 can be arranged on the first transmission member 22, and the second transmission member 32 can be sleeved on the second rotating member 31. When the first rotating member 21 drives the first transmission member 22 to reciprocate along the first direction, the second rotating member 31 located on the first transmission member 22 can synchronously rotate in the clockwise direction or the counterclockwise direction, thereby driving the clamping assembly 4 connected to the second transmission member 32 to continue to reciprocate along the first direction. In this way, the clamping assembly 4 can have two movement distances. It can be understood that the first movement distance can be the distance when the driving member 1 drives the first transmission member 22 to move, and the second movement distance can be the distance when the first transmission member 22 drives the second transmission member 32 to move.

[0033] In the transport mechanism of the present invention, when the driving member 1 drives the first transmission member 22 to move along the first direction through the first rotating member 21, the second transmission assembly 3 connected to the first transmission member 22 can drive the clamping assembly 4 to continue to move in the direction of movement of the first transmission member 22. In this way, the clamping assembly 4 can move a larger distance when subjected to a smaller driving force, effectively improving the transport efficiency of the transport mechanism and reducing energy consumption. In addition, the operating space required for the clamping assembly 4 is reduced, realizing the miniaturized design of the transport mechanism, thereby effectively improving the practicality and portability of the transport mechanism.

[0034] In some embodiments, Figure 1 and Figure 2 As shown, the transport mechanism also includes a fixed seat 5, on which a fixing member 51 is provided. The fixing member 51 is fixedly connected to the second transmission member 32. When the first transmission member 22 drives the second rotating member 31 to reciprocate along the first direction, the second transmission member 32 causes the clamping assembly 4 to reciprocate along the first direction under the action of the fixing member 51 and the second rotating member 31.

[0035] The driving member 1, the first transmission assembly 2, the second transmission assembly 3 and the clamping assembly 4 can all be tiltedly arranged on the fixing seat 5 to fix and support the above-mentioned components.

[0036] like Figure 2 As shown, the fixing member 51 can be specifically a clamping plate, through which the fixing member 51 can be clamped on the second transmission member 32 to fix the fixing seat 5 with the second transmission member 32. In this way, when the first transmission member 22 moves in the direction close to the object to be transported, the second rotating member 31 on the first transmission member 22 can move in the direction close to the object to be transported relative to the fixing member 51, and can also rotate clockwise to drive the second transmission member 32 to move in the direction close to the object to be transported, thereby realizing the synchronous movement of the clamping assembly 4 connected to the second transmission member 32. Conversely, when the first transmission member 22 moves in the direction away from the object to be transported, the second rotating member on the first transmission member 22 can move in the direction away from the object to be transported relative to the fixing member 51, and can also rotate counterclockwise to drive the second transmission member 32 to move in the direction away from the object to be transported.

[0037] In the above embodiment, when the second rotating member 31 drives the second transmission member 32 to reciprocate along the first direction, the fixing member 51 can be fixedly connected to the second transmission member 32, so that the second transmission member 32 can rotate in a clockwise direction or a counterclockwise direction around the second rotating member 31. This not only ensures that the clamping assembly 4 can continue to reciprocate along the first direction driven by the second transmission member 32, but also optimizes the structural layout of the conveying mechanism, effectively improving the rationality and compactness of the structure of the conveying mechanism.

[0038] In some embodiments, Figure 1 and Figure 3 As shown, the clamping assembly 4 includes a connecting member 41, and the clamping assembly 4 is connected to the second transmission member 32 through the connecting member 41. When the first transmission member 22 reciprocates along the first direction, the second transmission member 32 drives the clamping assembly 4 to reciprocate synchronously along the first direction through the connecting member 41.

[0039] The connecting member 41 may specifically be a clamping plate, which can be clamped on the second transmission member 32 to fix the clamping assembly 4 to the second transmission member 32 .

[0040] In the above embodiment, the clamping assembly 4 can be directly connected to the second transmission member 32 through the connecting member 41. This not only avoids the errors that may be caused by other indirect transmission methods, effectively improves the accuracy of the movement of the clamping assembly 4, but also simplifies the mechanical structure of the conveying mechanism, avoids complex transmission links, reduces energy loss during power transmission, and effectively improves the conveying efficiency of the conveying mechanism.

[0041] In some embodiments, Figure 4 As shown, the second transmission member 32 includes a first belt body 321 and a second belt body 322 which are arranged opposite to each other around the second rotating member 31 . The first belt body 321 is connected to the fixing member 51 , and the second belt body 322 is connected to the connecting member 41 .

[0042] It is understandable that the distance that the clamping assembly 4 moves under the drive of the second transmission member 32 can be controlled according to the specific connection position of the connecting member 41 on the second belt body 322. Specifically, when the setting position of the connecting member 41 is close to the object to be transported, the moving distance of the clamping assembly 4 is relatively short, and conversely, when the setting position of the connecting member 41 is far from the object to be transported, the moving distance of the clamping assembly 4 is relatively long.

[0043] In the above embodiment, when the second transmission member 32 is sleeved on the outside of the second rotating member 31, the fixing member 51 and the connecting member 41 can be respectively connected to the first belt body 321 and the second belt body 322 of the second transmission member 32, so that when the second transmission member 32 moves in the direction approaching the object to be transported, the second transmission member 32 can rotate clockwise around the second rotating member 31 under the action of the fixing member 51, and then the clamping assembly 4 continues to move in the direction approaching the object to be transported through the connecting member 41, so that the driving member 1 can drive the clamping assembly 4 to move two movement distances, effectively improving the driving efficiency of the driving member 1, and greatly improving the practicality and layout rationality of the transport mechanism.

[0044] In some embodiments, Figure 3 and Figure 4As shown, the transport mechanism further includes a connecting plate 6 , the second transmission assembly 3 is disposed on the first transmission member 22 via the connecting plate 6 , and the first transmission member 22 and the second transmission assembly 3 are respectively disposed on two opposite sides of the connecting plate 6 .

[0045] The connecting plate 6 may be in the shape of an elongated strip, and opposite sides of the connecting plate 6 may be respectively connected to the first transmission member 22 and the second rotating member 31 , and the second transmission member 32 may be sleeved on the outer side of the second rotating member 31 .

[0046] The length of the connecting plate 6 can be matched with the length of the first transmission member 22 and the length of the second transmission member 32 to reduce the structural stress concentration caused by the length mismatch and effectively improve the stability of the transport mechanism during the transport process.

[0047] In the above embodiment, the first transmission member 22 and the second transmission assembly 3 are respectively arranged on two opposite sides of the connecting plate 6, which can make the overall layout of the transport mechanism more compact, reduce the distance between the components, and effectively improve the utilization of space. In addition, due to the relative arrangement of the first transmission member 22 and the second transmission assembly 3, more efficient power transmission can be achieved, effectively reducing the energy loss during power transmission, and improving the transport efficiency of the transport mechanism.

[0048] In some embodiments, Figure 1 and Figure 3 As shown, the first rotating member 21 is a gear, and the first transmission member 22 is a rack. The rack has a toothed surface and a non-toothed surface. The gear acts on the toothed surface, and the non-toothed surface is connected to the connecting plate 6.

[0049] In the above embodiment, through the cooperation of the gear and the rack, the rotational motion of the gear can be converted into the linear motion of the rack. While realizing the conversion of the motion form, it also simplifies the mechanical connection structure of the first transmission component 2, saving the volume of the conveying mechanism and the space occupied.

[0050] In some embodiments, Figure 3 and Figure 4 As shown, the second rotating member 31 is a rotating wheel, the second transmission member 32 is a transmission belt, there are two rotating wheels, the two rotating wheels are respectively arranged on the side of the connecting plate 6 away from the rack, and the transmission belt is sleeved outside the two rotating wheels.

[0051] The two rotating wheels can be respectively inserted into the two ends of the connecting plate 6 away from the rack through the rotating shaft 7, and the transmission belt can be sleeved outside the two rotating wheels so that when a force is applied to the transmission belt, the transmission belt can rotate freely around the rotating wheels.

[0052] In the above embodiment, through the cooperation between the synchronous belt and the rotating wheel, not only the linear motion of the synchronous belt can be realized, but also the mechanical connection structure of the second transmission assembly 3 can be simplified, saving the space occupied by the conveying mechanism, making the structural layout of the entire conveying mechanism more compact and reasonable.

[0053] In some embodiments, Figure 3 and Figure 4 As shown, the two side edges of the connecting plate 6 are respectively provided with a first slide rail 61 and a second slide rail 62, the fixing member 51 and the clamping assembly 4 are respectively provided with a first slider 63 and a second slider 64, the first slider 63 is slidably arranged with the first slide rail 61, and the second slider 64 is slidably arranged with the second slide rail 62.

[0054] The first slide rail 61 and the second slide rail 62 may be arranged at intervals on both sides of the connecting plate 6 along the length direction of the connecting plate 6. The fixing member 51 may be provided with a first slider 63, and is slidably connected to the first slide rail 61 through the first slider 63. The clamping assembly 4 may be provided with a second slider 64, and is slidably connected to the second slide rail 62 through the second slider 64.

[0055] In the above embodiment, through the sliding connection between the first slider 63 and the first slide rail 61, and the sliding connection between the second slider 64 and the second slide rail 62, not only can the first transmission member 22 and the clamping assembly 4 be more stable during the movement, reducing the vibration or deviation generated during the movement, but also the first transmission member 22 and the clamping assembly 4 can have more precise linear motion, effectively improving the stability and accuracy of the conveying mechanism.

[0056] In some embodiments, the connecting plate 6 is provided with a plurality of adjustment holes (not shown in the figure) arranged at intervals, and the rotating wheel is connected to the connecting plate 6 through one of the plurality of adjustment holes.

[0057] The connecting plate 6 may be provided with a plurality of adjustment holes spaced apart along its length direction, and the operator may adjust the distance between the two rotating wheels and the length of the transmission belt through the adjustment holes, thereby flexibly adjusting the movement distance of the clamping assembly 4 according to the distance between the clamping assembly 4 and the object to be transported.

[0058] In the above embodiment, a plurality of adjustment holes can provide different connection positions, so that the distance between the two rotating wheels can be adjusted according to actual needs, thereby adjusting the movement distance of the clamping assembly 4, greatly improving the flexibility and adaptability of the transport mechanism.

[0059] In some embodiments, Figure 1 and Figure 2As shown, the clamping assembly 4 includes a rotating member 42 and a clamping jaw 43 . The clamping jaw 43 is connected to the connecting plate 6 via the rotating member 42 . The clamping jaw 43 rotates around its own axis driven by the rotating member 42 .

[0060] like Figure 1 and Figure 2 As shown, the number of the clamping jaws 43 can be two, and the two clamping jaws 43 are arranged at an interval. The rotating member 42 can drive the two clamping jaws 43 to rotate circumferentially around the axis of the rotating member 42, so that after one of the clamping jaws 43 clamps the object to be transported, the other clamping jaw 43 can be driven to rotate above the object to be transported and clamp the object to be transported. In this way, the clamping assembly 4 can clamp two objects to be transported at the same time, effectively improving the transport efficiency of the transport mechanism.

[0061] The rotating member 42 may specifically be a cylinder or other device that can drive the clamping jaw 43 to rotate, and the present application does not specifically limit the type of the rotating member 42 .

[0062] In the above embodiment, the rotating member 42 can drive the clamping jaw 43 to rotate so that the clamping jaw 43 can correspond to the position of the object to be transported. This not only allows the clamping jaw 43 to conveniently and accurately clamp the object to be transported, but also allows the clamping jaw 43 to have a wider clamping range to meet different usage scenarios, effectively improving the practicality and convenience of the clamping assembly 4.

[0063] According to another aspect of the present invention, a sample processing device is provided, which includes a workbench, a centrifugal assembly, a loading assembly and the conveying mechanism as described above, the workbench has a discharge port, the centrifugal assembly is arranged below the workbench, the conveying mechanism and the loading assembly are respectively arranged on the workbench, and the conveying mechanism is used to convey the object to be conveyed in the loading assembly to the centrifugal assembly through the discharge port.

[0064] The object to be transported can be a centrifuge tube, and the clamping assembly 4 of the transport assembly can clamp the centrifuge tube in the loading assembly and load the centrifuge tube into the centrifuge assembly. The centrifuge assembly can rotate quickly to generate centrifugal force in the centrifuge tube, thereby separating different substances in the centrifuge tube.

[0065] The sample processing device of the present invention includes the transport mechanism as described above. Since the transport mechanism has the beneficial effects as described above, the sample processing device including the transport mechanism must also have the beneficial effects as described above.
