Description

Technical Field

[0001] This invention relates to the field of gene sample detection technology, specifically to a gene detection sample oscillation and mixing device with precise speed control. Background Technology

[0002] Genetic sample testing involves collecting biological samples (such as blood, saliva, tissue, etc.) and conducting laboratory analysis to predict disease risk, guide treatment, or screen for genetic diseases.

[0003] The gene testing sample shaking and mixing device is a laboratory device specifically designed for gene sample processing. It achieves rapid and uniform mixing of samples and reagents through high-frequency vibration or rotation, ensuring the accuracy and repeatability of test results.

[0004] Conventional shaking mixing devices often suffer from insufficient speed control precision. When dealing with different types of gene samples and reagents, it is difficult to accurately adjust the shaking frequency and amplitude according to their characteristics, resulting in inconsistent mixing effects and affecting the reliability of test results. Moreover, the fixed structure of some devices' rotating components cannot flexibly adapt to sample containers of various sizes. When processing samples of different specifications, either the container is too large to be placed stably, or the container is too small to fully contact the shaking components, resulting in uneven mixing.

[0007] Furthermore, the fixed angle bracket and the main unit are integrated into one structure, and the two ends of the fixed angle bracket are vertically provided with holes for bolt installation and fixing. The stepless speed control knob and the control panel adopt a closed-loop feedback system and combine an encoder or Hall sensor to control the speed error within ±0.1%.

The shock absorber frame is installed at the bottom of the counterweight fixing seat, and the drive motor is vertically installed in the middle of the inside of the shock absorber frame. The connecting shaft seat is connected to the top power output end of the drive motor.

[0009] Furthermore, both the counterweight fixing seat and the shock absorber frame are made of damping alloy material, and the left and right ends of the counterweight fixing seat are installed and fixed on the upper end of the inner wall of the assembly groove. Moreover, both the counterweight fixing seat and the shock absorber frame are designed with dynamic balance to offset vibration and prevent resonance interference. The drive motor is a brushless direct drive motor to eliminate transmission chain errors and achieve millisecond-level response.

[0010] Furthermore, the frame structure includes a main frame, a docking seat, a guide rail, and a limiting block. The docking seat is integrally provided in the middle of the bottom of the main frame, and the guide rail is horizontally installed on the top of the main frame. Limiting blocks are installed at both ends of the guide rail.

[0011] Furthermore, the entire frame component is made of carbon fiber or aerospace aluminum alloy to reduce inertial hysteresis and improve response speed. The four diagonal holes at the connection between the docking seat and the connecting shaft seat are provided for bolt installation and fixing. The guide rail and the limiting block are connected by a sliding insertion structure. At the connection between the end of the limiting block away from the guide rail and the end of the main frame, two sets of holes are provided vertically at both ends for bolt installation and fixing.

[0012] Furthermore, the clamping component includes a slider, a positioning bolt, a support seat, and an anti-slip clamping block.

Moreover, the upper section of the support seat away from the positioning bolt is provided with an anti-slip clamping block.

[0013] Furthermore, the slider and the support base are integrated into a single structure, and the slider and the guide rail are connected and combined with each other using a slotted embedded structure.

[0014] This invention provides a gene detection sample oscillation and mixing device with precise speed control, which has the following beneficial effects: 1. This invention, through the combined arrangement of the device host and drive components, achieves speed control accuracy within ±0.1% through a closed-loop feedback system formed by the stepless speed control knob and control panel within the device host, combined with an encoder or Hall sensor, ensuring the stability of the sample oscillation and mixing process.

Combined with the vertical embedded structure of the drive component, the overall center of gravity is lowered by more than 30%, which effectively improves the anti-tipping ability of the equipment under high-speed oscillation conditions.

[0015] 2. This invention, through the combined arrangement of the transfer frame component and the clamping component, features a main frame made of carbon fiber or aerospace-grade aluminum alloy. This material choice not only reduces overall weight but also enhances structural rigidity, enabling the component to maintain a stable shape during high-frequency oscillation and reducing hysteresis caused by inertia, thereby improving speed response sensitivity.

[0018] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0019] like Figures 1 to 5As shown, a gene detection sample oscillation mixing device with precise speed control includes a main unit 1 and a driving component 2. The main unit 1 has the driving component 2 vertically embedded inside, and a rotating frame component 3 is horizontally connected to the top power output end of the driving component 2. Clamping components 4 are symmetrically installed at both ends of the top of the rotating frame component 3. The main unit 1 includes a main housing 101, a stepless speed control knob 102, a control panel 103, an assembly slot 104, and a fixed angle bracket 105. The stepless speed control knob 102 is installed on the front side of the main housing 101, and the control panel is obliquely embedded on the upper end of the side of the main housing 101 where the stepless speed control knob 102 is installed. 103. Furthermore, the top of the main unit 101 has a vertically opening assembly slot 104 for vertically embedding the drive component 2. The lower ends of both sides of the main unit 101 are symmetrically equipped with fixing angle seats 105. The fixing angle seats 105 and the main unit 101 are integrally formed. The two ends of the fixing angle seats 105 have vertically opening holes for bolt installation. The stepless speed control knob 102 and the control panel 103 employ a closed-loop feedback system combined with an encoder or Hall sensor to control the speed error within ±0.1%. The drive component 2 includes a counterweight fixing seat 201, a shock absorber frame 202, a drive motor 203, and a connecting shaft seat 2. 04. A shock absorber 202 is installed at the bottom of the counterweight mounting base 201, and a drive motor 203 is vertically installed in the middle of the shock absorber 202. A connecting shaft seat 204 is connected to the top power output end of the drive motor 203. Both the counterweight mounting base 201 and the shock absorber 202 are made of damping alloy material. The left and right ends of the counterweight mounting base 201 are fixed to the upper inner wall of the assembly groove 104. Both the counterweight mounting base 201 and the shock absorber 202 use dynamic balance design to offset vibration and prevent resonance interference. The drive motor 203 is a brushless direct drive motor to eliminate transmission chain errors and achieve millisecond-level response. Due to the characteristics of the machine, the drive motor 203 can directly convert electrical energy into mechanical energy during operation, reducing energy loss and error accumulation that may be caused by intermediate transmission links. This millisecond-level response speed enables the rotating frame component 3 to reach the preset oscillation frequency and amplitude in a very short time, providing a strong guarantee for the rapid and uniform mixing of samples and reagents. As the connecting component between the drive motor 203 and the rotating frame component 3, the design precision and strength of the connecting shaft 204 are crucial. It must not only be able to withstand the strong torque output by the drive motor 203, but also ensure a stable connection during high-frequency oscillation to prevent the overall performance of the equipment from being affected by loosening or wear.

[0020] like Figures 1 to 5As shown, the frame assembly 3 includes a main frame 301, a docking seat 302, a guide rail 303, and a limiting block 304. The docking seat 302 is integrally provided at the bottom center of the main frame 301, and the guide rail 303 is horizontally installed at the top of the main frame 301. Limiting blocks 304 are installed at both ends of the guide rail 303. The frame assembly 3 is made of carbon fiber or aerospace aluminum alloy to reduce inertial hysteresis and improve response speed. Holes for bolt installation are provided at the four diagonal corners of the connection between the docking seat 302 and the connecting shaft seat 204. The guide rail 303 and the limiting block 304 are connected by a sliding insertion structure, and the ends of the limiting block 304 away from the guide rail 303 are perpendicular to the connection between the two ends of the main frame 301. The clamping component 4 has two sets of holes for bolt installation and fixing. It includes a slider 401, a positioning bolt 402, a support base 403, and an anti-slip block 404. The top of the slider 401, away from the vertical central axis of the rotating frame component 3, is vertically threaded with the positioning bolt 402. The end of the slider 401 away from the positioning bolt 402 is provided with the support base 403, and the upper section of the support base 403 away from the positioning bolt 402 is equipped with the anti-slip block 404. The slider 401 and the support base 403 are integrally formed, and the slider 401 and the guide rail 303 are interconnected using a slotted embedded structure. After receiving power from the driving component 2, the rotating frame component 3 begins to oscillate around its vertical central axis at a high frequency. As the main component of the frame 3, the choice of carbon fiber or aerospace aluminum alloy for component 301 ensures structural rigidity while minimizing its own weight, reducing hysteresis caused by inertia, and improving speed response sensitivity. The guide rail 303 is horizontally mounted on the top of the main frame 301, providing a horizontal track for the clamping component 4. Its surface is precision-machined to ensure smooth and accurate sliding. Limit blocks 304 are installed at both ends of the guide rail 303, playing a crucial role in preventing the slider 401 from derailing during oscillation, ensuring the safety of the sample mixing process. Driven by the frame 3, the clamping component 4 reciprocates horizontally along the guide rail 303. Simultaneously, the slider 401 and the guide rail 301... The slotted, embedded connection between components 3 allows clamping member 4 to quickly position and clamp samples of different sizes, adjusted via the vertical thread of positioning bolt 402. This design not only enhances the versatility of the equipment but also improves sample processing efficiency. The anti-slip clamping blocks 404 are made of elastic silicone, whose soft and elastic properties increase friction with the sample container surface while avoiding scratches that might occur with traditional hard clamping blocks, protecting sample integrity and providing strong assurance for the accuracy of gene detection. In actual operation, the user simply places the sample container between the anti-slip clamping blocks 404 of clamping member 4 and adjusts the clamping force by rotating positioning bolt 402 to ensure the sample container is securely clamped.The desired oscillation frequency and amplitude can be set via the stepless speed control knob 102 on the main unit 1 and the control panel 103. The device will then operate automatically according to the preset parameters, achieving rapid and uniform mixing of samples and reagents.

[0021] In summary, as Figures 1 to 5 As shown, this gene detection sample oscillation mixing device with precise speed control is used by first placing the device stably on the experimental operating table and securing it firmly with bolts using the fixed corner brackets 105 on both sides of the main unit 101 to prevent displacement or overturning during high-speed oscillation. Next, the clamping components 4 are adjusted according to the size of the sample container by rotating the positioning pin 402 on the slider 401. Since the slider 401 and the guide rail 303 are connected by a slotted embedded connection, the vertical thread adjustment function of the positioning pin 402 allows the slider 401 to move horizontally on the guide rail 303, thereby changing the distance between the two clamping components 4 to accommodate sample containers of different lengths. The sample container is then placed between two anti-slip clamps 404. The anti-slip clamps 404 are made of elastic silicone material, whose soft and elastic properties can closely fit the surface of the sample container, increasing friction while avoiding scratches on the sample container and ensuring that the sample container is securely clamped. After the sample container is clamped, the required oscillation frequency and amplitude are set by the stepless speed control knob 102 and control panel 103 on the main unit 1. The stepless speed control knob 102 and control panel 103 adopt a closed-loop feedback system and are combined with an encoder or Hall sensor to control the speed error within ±0.1%, ensuring the stability of the sample oscillation and mixing process. After the parameters are set, the device is started and the drive component 2 starts to work. The drive motor 203 adopts a brushless direct drive motor, which can directly convert electrical energy into mechanical energy, reducing the energy loss and error accumulation that may be caused by intermediate transmission links, and achieving millisecond-level response. The power output by the drive motor 203 is transmitted to the docking seat 302 of the rotating frame component 3 through the connecting shaft seat 204, so that the rotating frame component 3 performs high-frequency oscillation motion around its vertical central axis. The main frame 301 of the rotating frame component 3 is made of carbon fiber or aerospace aluminum alloy. This material not only reduces the overall weight but also enhances the structural rigidity, enabling it to maintain a stable shape during high-frequency oscillation, reducing hysteresis caused by inertia, and improving the sensitivity of speed response. The guide rail 303 is horizontally mounted on the top of the main frame 301, providing a track for the horizontal movement of the clamping component 4. Its surface is precision machined to ensure smooth and accurate sliding. Limiting blocks 304 are installed at both ends of the guide rail 303 to prevent the slider 401 from derailing during oscillation, ensuring the safety of the sample mixing process. The clamping component 4 is located on the rotating frame. Driven by component 3, the guide rail 303 reciprocates horizontally, achieving rapid and uniform mixing of samples and reagents. During equipment operation, the counterweight fixing seat 201 and the shock absorber frame 202 are both made of damping alloy material and use dynamic balance design to offset vibration energy. Combined with the millisecond-level response characteristics of the brushless direct drive motor, the stability of equipment operation is significantly improved while eliminating transmission chain errors. After the sample is mixed, the equipment is turned off, the sample container is removed, and subsequent gene detection operations can be performed. Through the coordinated work of various components, this device provides reliable, efficient, and accurate technical support for gene detection sample processing.
