Description

Technical Field

[0001] The utility model relates to the technical field of reagent preparation, in particular to a batch reagent preparation device. Background Art

[0002] At present, in the process of reagent preparation, manual preparation is generally adopted. When samples need to be prepared in batches, the manual preparation method not only greatly limits the efficiency of reagent preparation, but also is not conducive to improving the accuracy of reagent preparation. Based on this, setting up dedicated automatic processing equipment to prepare reagents in batches can quickly, efficiently and accurately process the reagents to meet the needs of subsequent detection and analysis.

[0003] Chinese utility model patent CN218026095U discloses a plasmid supernatant preparation instrument, including a container and a filtering container; a plurality of containers are arranged horizontally in a straight line, wherein bacterial colonies are contained, and the bacterial colonies are loaded by a swinging rotating frame, and a lifting capping module is installed directly above the container, and the capping module is used to remove the bottle cap on the top of the container; reagent A, reagent B and reagent C are injected into the container one by one and in order through the liquid adding head of the liquid adding module, and the liquid adding head is movably installed above the container; the container is driven by a swinging module installed on one side of the rotating frame, and the rotating frame rotates and swings, so that the container swings back and forth like a pendulum; a plurality of filtering containers are arranged horizontally in a straight line on the front side of the container, and a three-axis manipulator is arranged above the filtering container, and the three-axis manipulator synchronously grabs the container and moves it to the top of the filtering container for pouring, so that the solution in the container flows into the filtering container for filtration.

[0004] It can be found that in the plasmid supernatant preparation instrument, the container is grabbed to the top of the filter container mainly through the setting of the three-axis manipulator to realize the transfer of the container in the horizontal direction. With this structure, although the transfer of containers in different positions can be realized, due to the limited number of containers that can be grabbed by the three-axis manipulator in one action, only one container can be grabbed in most cases, which cannot be well matched with the batch reagent preparation process. Specifically, when batch reagents need to be prepared, not only a variety of different types and specifications of containers need to be temporarily stored inside the equipment to hold different types of reagent samples respectively, but also containers of different types and specifications need to be transferred as a whole so that the equipment can extract reagent samples from different containers for reagent preparation. Obviously, the above-mentioned equipment cannot meet the batch transfer requirements of containers, which limits the application scenarios of the equipment to a certain extent, and is not conducive to the improvement of batch reagent preparation efficiency.

[0005] This shows that the prior art needs to be further improved and enhanced. Utility Model Content

[0025] When the supporting plate switches from the retracted position to the extended position, the supporting plate extends under the tray and can cooperate with the recessed portion to support the tray.

[0026] In some embodiments, the length of the support plate is no less than half the length of the tray.

[0027] In some embodiments, the tray is evenly distributed with a number of limiting grooves for fixing the container;

[0028] The sizes of the plurality of limit grooves are the same so as to fix containers of the same specifications; or

[0049] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein.

[0050] Reference Figure 1-Figure 6 As shown, the embodiment of the utility model provides a batch reagent preparation device, which is applied to a workbench 100, and the workbench 100 includes a table 110 and a storage space 120 located below the table 110, and the table 110 is provided with a transfer channel 130 connected to the storage space 120. The batch reagent preparation device includes a tray 200, a rack 300, a transfer mechanism 400 and a telescopic support plate 500; wherein the tray 200 contains a container 210, and the rack 300 is arranged in the storage space 120 to carry the tray 200; the transfer mechanism 400 is located in the transfer channel 130, and has a transfer path for horizontal movement along the extension direction of the transfer channel 130, and for moving up and down in the transfer channel 130; the telescopic support plate 500 is connected to the transfer mechanism 400, and can move to the bottom of the tray 200 along its telescopic direction, and transfer the tray 200 from the storage space 120 to the table 110 along the transfer path.

[0051] It should be noted that the container 210 in the present application may contain a collected sample or a solution for preparing a reagent, and the types of samples or solutions contained in different containers 210 may be the same or different. For example, when the same type of reagent (such as 25% sulfuric acid reagent) needs to be prepared in batches, the solution in each container 210 may be a sulfuric acid solution; when different types of reagents need to be prepared in batches, the solution in each container 210 may be a sulfuric acid solution, a hydrochloric acid solution, a methanol solution, an ethanol solution, and other different types. In addition, the container 210 may also have a variety of different specifications, such as 2ml, 15ml, 50ml, 100ml, 500ml, etc. The present application does not limit the type of solution or sample contained in the container 210, and the specifications of the container 210.

[0052] It should also be noted that the workbench 100 in the present application provides a platform for users to be equipped with reagents, and in order to improve the efficiency of reagents, a reagent preparation unit 140 can also be set on the table 110 of the workbench 100 to realize the automated batch preparation of reagents. Wherein, regarding the specific structure of the reagent preparation unit 140, those skilled in the art can reasonably configure it according to the design requirements and user needs of the product, which is not limited here. For example, the reagent preparation unit 140 may include a gripping mechanism (not marked in the figure) and a clamp (not marked in the figure) arranged on the table 110 respectively, and the gripping mechanism can grip the container 210 on the table 110 along the X-axis, Y-axis and Z-axis movement, and a liquid collection assembly (not marked in the figure) is also provided at its end, and the clamp is used to fix and clamp the container 210. First, the grabbing mechanism can grab the empty container placed on the table 110 to the clamp. After the multiple containers containing solutions in the accommodating space 120 are transferred to the table 110, the grabbing mechanism moves to the top of the container to be extracted, and the liquid extraction component starts to extract the solution in the container. After the grabbing mechanism moves to the top of the empty container, the extracted solution is injected into the empty container. By repeating several actions like this, the automatic preparation of specific reagents can be realized.

[0053] It is understandable that, although the automated preparation of reagents is achieved by arranging the relevant reagent preparation unit 140 on the table 110, in order to be compatible with the reagent preparation unit 140 and ensure efficient preparation of reagents, on the one hand, it is not only necessary to store a large number of different types of solutions in the accommodation space 120 of the workbench 100 to make reserves for the preparation process of the reagents; on the other hand, it is also necessary to configure a device that can realize the synchronous batch transfer of multiple containers 210 of different specifications and styles, so as to transfer the containers 210 in the accommodation space 120 to the designated positions on the table 110.

[0054] In view of this, the present application provides a batch reagent preparation device, wherein a plurality of containers 210 can be contained in a tray 200, and the entire tray 200 can be lifted by a single telescopic movement of the telescopic support plate 500, thereby realizing the overall batch transfer of the plurality of containers 210, which is beneficial to the improvement of the batch reagent preparation efficiency and expands the application scenarios of the device. In addition, the transfer path of the transfer mechanism 400 in the transfer channel 130 only involves the horizontal and vertical directions, and the transfer mechanism 400 itself cannot rotate. Compared with some gripping devices with multiple degrees of freedom in the prior art, this arrangement method has better stability of the transfer mechanism 400, which is beneficial to the long-term reliable operation of the equipment.

[0055] In some embodiments, reference Figure 4 and Figure 5 As shown, the transfer mechanism 400 includes a translation assembly 410 and a lifting assembly 420. The translation assembly 410 includes a horizontal guide rail 411 disposed in the accommodating space 120, a horizontal slider 412 matched with the horizontal guide rail 411, and a first driving member 413 for driving the horizontal slider 412 to move along the horizontal guide rail 411; the lifting assembly 420 includes a vertical guide rail 421 perpendicular to the horizontal guide rail 411, a vertical slider 422 matched with the vertical guide rail 421, and a second driving member 423 for driving the vertical slider 422 to move along the vertical guide rail 421. In addition, the horizontal slider 412 is connected to the vertical guide rail 421, and the vertical slider 422 is connected to the telescopic support plate 500, so that the telescopic support plate 500, driven by the first driving member 413 and the second driving member 423, respectively moves up and down along the vertical guide rail 421 and translates along the horizontal guide rail 411.

[0056] By setting the translation assembly 410 and the lifting assembly 420, the telescopic support plate 500 connected to the transfer mechanism 400 can move along the extension direction of the transfer channel 130 and move up and down in the transfer channel 130 under the drive of the first driving member 413 and the second driving member 423. Since the transfer mechanism 400 of this structure can only move in translation, the movement process of the telescopic support plate 500 is more stable and reliable.

[0057] It is understandable that there are many different implementations of the specific structure of the transfer mechanism 400. In addition to the above-mentioned structure of the translation assembly 410 and the lifting assembly 420, the movement of the telescopic support plate 500 can also be realized by directly using two vertically arranged linear modules. The present application does not limit the specific structure of the transfer mechanism 400.

[0058] In some embodiments, reference Figure 6As shown, the telescopic support plate 500 includes a bottom plate 510, a telescopic assembly 520 and a supporting plate 530. Among them, one end of the bottom plate 510 is connected to the vertical slider 422, the telescopic assembly 520 is arranged on the surface of the bottom plate 510, and the supporting plate 530 is connected to the telescopic slider 522. Further, the telescopic assembly 520 includes a telescopic guide rail 521, a telescopic slider 522 matched with the telescopic guide rail 521, and a third driving member (not shown in the figure) for driving the telescopic slider 522 to move along the telescopic guide rail 521; under the drive of the third driving member, the supporting plate 530 telescopically moves along the telescopic guide rail 521 to realize the switching of the telescopic guide rail 521 between the retracted position and the extended position.

[0059] When the telescopic pallet 500 transfers the tray 200 in the accommodating space 120 to the table 110, the telescopic pallet 500 needs to enter and exit the accommodating space 120 through the transfer passage 130. Therefore, the present application reasonably configures the sizes of the bottom plate 510, the supporting plate 530 and the transfer passage 130 to avoid interference between the telescopic pallet 500 and the transfer passage 130 during movement as much as possible.

[0060] Preferably, the lengths of the base plate 510 and the support plate 530 are configured to be no greater than the width of the transfer channel 130, so that the projection of the base plate 510 on the workbench 100 is located in the transfer channel 130; and, in the retracted position, the projection of the support plate 530 on the workbench 100 is also located in the transfer channel 130; and in the extended position, the projection of the support plate 530 on the workbench 100 is located in the table top 110.

[0061] In some embodiments, a recessed portion (not shown in the figure) is formed at the bottom of the tray 200; when the support plate 530 switches from the retracted position to the extended position, the support plate 530 extends under the tray 200 and can cooperate with the recessed portion to support the tray 200.

[0062] The recessed portion may be a groove formed at the bottom of the tray 200, or may be formed by flanges extending outward from the four corners of the bottom of the tray 200. The present application does not limit the specific structure of the recessed portion. By setting the recessed portion, the supporting effect of the supporting plate 530 on the tray 200 can be improved, thereby facilitating the improvement of the stability of the tray 200 during transportation.

[0063] In addition, the surface of the supporting plate 530 may be provided with an anti-slip layer to further enhance the supporting effect of the supporting plate 530 on the tray 200 .

[0064] Furthermore, the length of the support plate 530 is not less than half the length of the pallet 200. This arrangement can make the center of gravity of the pallet 200 fall better within the supporting range of the support plate 530, so as to further improve the supporting effect of the support plate 530 on the pallet 200. In addition, in order to allow the pallet 200 to smoothly enter and exit the transfer channel 130 during the transfer process, the width of the pallet 200 should not be greater than the width of the transfer channel 130.

[0065] In some embodiments, the tray 200 is evenly distributed with a plurality of limiting grooves (not shown in the figure) for fixing the containers 210; wherein, the plurality of limiting grooves have the same size to achieve fixation of containers 210 of the same specifications; or, the plurality of limiting grooves have different sizes to achieve fixation of containers 210 of different specifications.

[0066] Among them, the shape of the limiting groove is adapted to the shape of the container 210. For example, when the container 210 is round, the limiting groove is a round groove; when the container 210 is square, the limiting groove is a square groove. This application does not limit the specific shape of the limiting groove.

[0067] Exemplarily, according to the different specifications and types of the container 210, the tray 200 can be divided into a 3ml tray 200, a 15ml tray 200, a 50ml tray 200, a 500ml tray 200, and a cuvette tray 200, etc. Among them, the 3ml tray 200 is evenly distributed with 5ⅹ7 limit slots to fix 35 3ml sample bottles respectively; the 15ml tray 200 is evenly distributed with 5ⅹ7 limit slots to fix 35 15ml test tubes respectively; the 50ml tray 200 is evenly distributed with 4ⅹ6 limit slots to fix 24 50ml test tubes respectively; the 500ml tray 200 is evenly distributed with 3ⅹ4 limit slots to fix 12 500 sample bottles respectively; the cuvette tray 200 is evenly distributed with 6ⅹ10 limit slots to fix 60 cuvettes respectively.

[0068] In other embodiments, reference Figure 4 As shown, there are multiple trays 200, and the rack 300 forms multiple storage layers from top to bottom, and multiple trays 200 are evenly arranged in the multiple storage layers. Different types of trays 200 can be stored on different storage layers, and the setting of multiple storage layers is conducive to the batch storage of containers 210 of different types and specifications, thereby facilitating the smooth progress of the subsequent batch preparation process of reagents.

[0069] Furthermore, the sizes of the plurality of limiting grooves in any tray 200 are the same, and at least two of the plurality of trays 200 have different limiting groove sizes. This arrangement enables the plurality of trays 200 to respectively accommodate at least two containers 210 of different specifications and types, thus expanding the storage range of the rack 300 for the solution to a certain extent.

[0070] In some embodiments, reference Figure 1 As shown, a running wheel 150 is provided at the bottom of the workbench 100. The setting of the running wheel 150 facilitates the movement of the workbench 100, so as to facilitate the user to transport and transfer the equipment. Among them, there can be multiple running wheels 150, and the multiple running wheels 150 are evenly distributed on the bottom wall of the workbench 100.
