Description

Technical Field

[0001] This application relates to the field of laboratory testing equipment technology, specifically to a reagent shaking device. Background Technology

[0002] Currently, in cell-like experiments, it is necessary to shake the reagents. Shaking helps to evenly distribute the reactants and allows the chemical reaction to proceed more quickly. The correct shaking method is crucial to the experimental results. In the prior art, such as the technical solution with patent number CN201410347425.X, a fully automated heating and shaking magnetic separation device is disclosed. This device integrates a magnetic separation device, a heating device, and a shaking device into one unit, which fully ensures the magnetic separation, thorough mixing, and heating incubation at a certain temperature of the solution in the microplate, thus ensuring the integrity of the function.

[0003] However, in the existing technical solutions, when the reagent is shaken, if the working conditions have high requirements for the reagent environment, it is inconvenient to use an auxiliary structure that follows the shaking trajectory to support the shaking. The existing support plate has great limitations in supporting the device during shaking, thus limiting the shaking frequency and consequently limiting the shaking effect. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0005] This application provides a reagent shaking device, comprising:

[0006] A platform unit, on which a standard plate fixing assembly is provided;

[0007] A multi-directional moving unit is connected to the platform unit;

[0008] A driving unit, which cooperates with the multi-directional moving unit, is used to drive the multi-directional moving unit to move in the XY plane of a given coordinate system, thereby driving the platform unit to move and form a moving trajectory.

[0009] Furthermore, the multi-directional moving unit includes a first moving plate, a second moving plate slidably connected to the first moving plate, and a base slidably connected to the second moving plate, wherein the first moving plate is fixedly connected to the platform unit.

[0010] Furthermore, the driving unit includes a drive motor and an eccentric wheel connected to the drive shaft of the drive motor. The eccentric wheel is connected to the first moving plate bushing, and the first moving plate drives the platform unit to form the movement trajectory in the XY plane of a given coordinate system.

[0011] Furthermore, a first slide rail is provided on the second movable plate along the X-axis of the given coordinate system, and the first movable plate is slidably disposed on the second movable plate. A second slide rail is provided on the base along the Y-axis of the given coordinate system, and the second movable plate is slidably disposed on the base. The moving directions of the first movable plate and the second movable plate intersect.

[0012] Furthermore, the reagent shaking device also includes a shaking reset sensor, which is disposed on the base and is used to detect the position of the stage unit.

[0013] Furthermore, the label fixing assembly includes a plurality of positioning corner seats fixedly disposed on the upper end face of the platform unit, the positioning corner seats being arranged to form a label fixing area.

[0014] Furthermore, the inner surface of the positioning angle seat is provided with a clamping spring.

[0015] Furthermore, a heating unit is provided on the stage unit. The heating unit includes a heating film and a heat conduction block. The heating film is disposed below the heat conduction block, and the heat conduction block is disposed on the upper end surface of the stage unit.

[0016] Furthermore, the heating unit also includes a temperature sensor, which is in contact with the heat conduction block.

[0017] Furthermore, the heating unit also includes a temperature fuse, which is connected to the heat conduction block.

[0018] This application has at least the following beneficial effects:

[0019] In this application, the support end simultaneously undertakes the functions of driving the driving unit to form a moving trajectory in the XY plane and providing stable support for the driving unit. This ensures the stability of the reagent in the standard plate when the driving unit moves to shake and mix it, thereby ensuring that the driving unit can move at a high speed without instability, thus improving the efficiency of shaking and mixing the reagent in the standard plate.

[0038] The embodiments of this application are described in detail below with reference to the accompanying drawings.

[0039] Example

[0040] like Figures 1-8 As shown, the reagent shaking device in this embodiment includes a stage unit 1, a driving unit 3, and a multi-directional moving unit 4. A label fixing assembly 2 is provided on the stage unit 1 to fix the reagent label to the end face of the stage unit 1. The driving unit 3 is located below the stage unit 1 and is connected to it. The driving unit 3 drives the stage unit 1 to form a moving trajectory in the XY plane of a given coordinate system. In this embodiment, the driving unit 3 drives the stage unit 1 to perform a circular vortex motion in the XY plane, meaning the moving trajectory formed by the stage unit 1 in the XY plane of the given coordinate system is circular. By driving the reagent label on the stage unit 1 to perform a circular vortex motion, the reagent is shaken and mixed. The multi-directional moving unit 4 is located below the stage unit 1 and... The moving unit 4 has a support end 45, which is fixedly connected to the lower end of the stage unit 1. The driving unit 3 drives the stage unit 1 to move through the support end 45. In other words, the support end 45 has the functions of both driving the stage unit 1 to move and supporting the stage unit 1. In this embodiment, the driving unit 3 drives the support end 45, and the support end 45 drives the stage unit 1 to perform a circular vortex motion in the XY plane. That is to say, the stage unit 1 will always be supported by the support end 45 during the circular vortex motion, so that the oscillation and shaking of the reagent plate is more stable, thereby increasing the rotational speed of the oscillation and shaking, so that the maximum speed of the circular vortex motion can reach 3000 rpm, ensuring that the reagent in the reagent plate is fully shaken.

[0041] like Figure 5 and Figure 6As shown, the drive unit 3 specifically includes a drive motor 31 and an eccentric wheel 32. The eccentric wheel 32 is connected to the drive end of the drive motor 31, and the eccentric wheel 32 is connected to the platform unit 1 and rotates along its axis. The eccentric wheel 32 is axially connected to the support end 45. Specifically, a bearing is fitted on the eccentric wheel, and the eccentric wheel 32 is inserted into the interior of the support end 45 and can rotate relative to the support end 45, driving the support end 45 to perform a circular vortex motion in the XY plane. The support end 45 drives the platform unit 1 to move in a given direction. The eccentric wheel 32 performs a circular vortex motion in the XY plane of the coordinate system. More specifically, the axis of the eccentric wheel 32 is not on the same straight line as the axis of rotation of the drive end of the drive motor 31. When the drive end of the drive motor 31 drives the eccentric wheel 32 to rotate, the axis of the eccentric wheel 32 will form a circular vortex motion trajectory, so that the stage unit 1 performs a circular vortex motion under the driving action of the support end 45 and the driving action of the eccentric wheel 32, and efficiently shakes the reagent in the reagent plate.

[0042] It should also be noted that, such as Figure 7 and Figure 8 As shown, the reagent shaking device in this embodiment also includes a base 5, and the multi-directional moving unit 4 also includes a first moving plate 41 and a second moving plate 42. The support end 45 is fixedly disposed on the first moving plate 41, the first moving plate 41 is movably disposed on the second moving plate 42, the second moving plate 42 is movably disposed on the base 5, and the moving directions of the first moving plate 41 and the second moving plate 42 intersect and are perpendicular to each other. The second moving plate 42 is used to move and support the first moving plate 41, while the first moving plate 41 is used to move and provide support force to the support end 45 during the moving process. Specifically, a first slide rail 43 is provided on the second movable plate 42 along the X-axis of the given coordinate system, and the first movable plate 41 is slidably disposed on the second movable plate 42. A second slide rail 44 is provided on the base 5 along the Y-axis of the given coordinate system, and the second movable plate 42 is slidably disposed on the base 5. When the first slide rail 43 and the second slide rail 44 move along the X-axis and Y-axis at a given speed respectively, the first support plate 41 can maintain the same moving trajectory as the support end 45, and provide support at all times during the circular vortex motion of the support end 45.

[0043] In other words, when the stage unit 1 performs circular vortex motion in the XY plane, its rotational speed is limited if it is unsupported, which is not conducive to efficient shaking and mixing. In order to solve this problem, this embodiment sets up a multi-directional moving unit 4, and ensures that the support end 45 of the multi-directional moving unit 4 can always maintain the same moving trajectory as the stage unit 1 when it performs circular vortex motion in the XY plane. This ensures that the circular vortex motion of the stage unit 1 can reach a higher rotational speed, thereby improving the shaking efficiency of the reagent.

[0044] like Figure 7As shown, the reagent shaking device in this embodiment also includes a shaking reset sensor 6, which is mounted on the base 5. Since this embodiment needs to be reused during the experiment, after one round of shaking, the drive unit 3 will stop moving and the reagent will be replaced by the sample dispensing arm. Therefore, this embodiment is equipped with a shaking reset sensor 6 to ensure that the reset accuracy of the stage unit 1 reaches ±0.02mm. This also moves the entire reagent shaking device of this embodiment to the workstation state to cooperate with the sample dispensing arm to accurately aspirate the reagent plate. The setting of the shaking reset sensor 6 prevents the stop position from deviating and affecting the experiment.

[0045] like Figure 2 , Figure 3 and Figure 4 As shown, the label fixing assembly 2 includes four positioning corner seats 21 fixedly disposed on the upper end face of the stage unit 1. The positioning corner seats 21 are arranged to form a label fixing area 22, which is a rectangular area and adapted to the reagent label, so that the reagent label can be fixed at the four corners of the reagent label by the four positioning corner seats 21. The inner surface of the positioning corner seats 21 is provided with clamping springs 23, which can perform loading and unloading operations on the reagent label.

[0046] The reaction of the reagents needs to be carried out under suitable temperature conditions during the shaking and mixing process, preferably, such as... Figure 3 and Figure 7 As shown, a heating unit 7 is provided on the stage unit 1 in this embodiment. The heating unit 7 includes a heating film 71 and a heat conduction block 72. The heating film 71 is disposed below the heat conduction block 72, and the heat conduction block 72 is disposed on the upper end surface of the stage unit 1. The heat conduction block 72 abuts against the reagent label. The heating film 71 generates heat and conducts the heat to the reagent label through the heat conduction block 72, thereby increasing the temperature of the reagent.

[0047] Heating unit 7 also includes a temperature sensor 73, which is in contact with the heat conduction block 72. Heating unit 7 also includes a temperature fuse, which is connected to the heat conduction block 72. The reagent plate is heated by contact between the heat conduction block 72 and the reagent plate. Simultaneously, the temperature error is controlled within ±0.1°C by the temperature sensor 73 and the temperature fuse, allowing for better analysis of reagent effects. Furthermore, in conjunction with the oscillation of drive unit 3, oscillation and incubation can be performed simultaneously, improving experimental efficiency and saving time.

[0048] The above embodiments are used to further illustrate this application, but do not limit this application to these specific implementations. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be understood as falling within the protection scope of this application.
