Description

Technical Field

[0001] This invention relates to the field of reagent testing equipment, and in particular to a reagent turntable device and a reagent turntable leveling method. Background Technology

[0002] In reagent testing instruments, the reagent turntable device is the core component for realizing the coordination of reagent transfer and detection. It typically includes a disc body for carrying the reagent disc cartridge and a drive component (such as a motor) for driving the disc body to rotate. The drive component has a drive shaft, and the disc body needs to be connected to the drive shaft through a corresponding structure to rotate synchronously with the drive shaft, ensuring that each detection position on the reagent disc cartridge can flow in an orderly manner.

[0003] To complete reagent testing, a fixed optical acquisition and detection system is installed below the reagent turntable. During testing, the turntable rotates the reagent disc holder, ensuring that each detection position passes over and stops above the optical acquisition and detection system to complete optical acquisition. The vertical height accuracy between the plane of the turntable supporting the reagent disc holder and the optical acquisition and detection system directly determines the accuracy of the reagent test results. If the height deviation exceeds the allowable range, it will lead to significant deviations in the calculated reagent test results.

[0004] However, the connection structure between the disk and the drive shaft in existing reagent turntable devices has obvious defects: the fixing components (such as the fixing disk) used to connect the disk and the drive shaft mostly adopt a clearance fit and are fixed to the drive shaft by set screws. This connection method is prone to causing the disk to tilt. At the same time, the circular runout error of the drive shaft itself and the installation error during the assembly of various components will continue to accumulate, eventually causing the plane of the disk bearing the reagent disk interlocking card to have a runout error in vertical height with the optical acquisition and detection system. This cannot meet the instrument's requirements for detection accuracy. Moreover, the existing structure lacks an effective design to specifically adjust the disk's levelness and compensate for the above errors, making it difficult to solve the problem of insufficient height accuracy. Summary of the Invention

[0005] The main objective of this invention is to overcome the deficiency of existing reagent turntable devices in that they lack a structure that can specifically adjust the level of the turntable to compensate for errors. This invention proposes a reagent turntable device and a reagent turntable leveling method. This invention can not only effectively adjust the level of the turntable to compensate for the height deviation caused by related errors, but also has the advantages of low cost and simple operation.

[0006] The present invention adopts the following technical solution:

[0007] A reagent turntable device includes a turntable body and a driving component. The driving component is provided with a driving shaft, and also includes a fixed base and several adjusting mechanisms. The fixed base is fixedly sleeved outside the driving shaft and has a support surface that fixes and supports the turntable body. The several adjusting mechanisms are circumferentially spaced around the axis of the driving shaft, and each adjusting mechanism is located between the turntable body and the support surface. By operating the adjusting mechanisms, the relative distance between the turntable body and the support surface at corresponding adjustment positions is changed, thereby adjusting the levelness of the turntable body.

[0008] The support surface is provided with a plurality of first fixing holes that are circumferentially spaced around the axis of the drive shaft. The disc body is provided with a plurality of second fixing holes that are corresponding to and communicate with the first fixing holes in the area corresponding to the support surface. The disc body and the fixing seat are fixed by a plurality of fixing members passing through the corresponding first fixing holes and second fixing holes. At least one adjustment mechanism is provided between two adjacent second fixing holes.

[0009] The disc body is provided with a plurality of adjustment holes circumferentially spaced around the axis of the drive shaft in the area corresponding to the support surface. The adjustment holes penetrate the disc body in the axial direction of the drive shaft. The adjustment mechanism passes through the corresponding adjustment hole and forms a fit with the support surface. The adjustment mechanism and the adjustment hole are threaded together, so that the adjustment mechanism can move relative to the adjustment hole along the axial direction of the drive shaft.

[0010] The end of the adjustment mechanism facing the support surface is the top pressure end. By rotating the adjustment mechanism, the top pressure end moves with the adjustment mechanism to leave or abut against the support surface, thereby changing the relative distance between the disc body and the support surface corresponding to the position of the adjustment hole.

[0011] The disk body has a first mounting hole in the middle that extends along the axis of the drive shaft; the fixing seat passes through the first mounting hole and has at least one radially extending first limiting part on its outer periphery; the inner wall of the first mounting hole has at least one second limiting part to cooperate with the corresponding first limiting part to achieve circumferential relative fixation between the fixing seat and the disk body.

[0012] The fixed base is also provided with a positioning post extending along the axial direction of the drive shaft on the support surface, and the disc body is provided with a positioning hole for the positioning post to pass through to achieve positioning.

[0013] The mounting base is provided with a second mounting hole that passes through the axis of the drive shaft and allows the drive shaft to pass through. The mounting base is also provided with at least one third fixing hole that is radially connected to the second mounting hole. The third fixing hole is located near the end of the second mounting hole that is opposite to the support surface. At least one fastener is inserted into the corresponding third fixing hole and pressed against the drive shaft to achieve a fixed connection between the drive shaft and the mounting base.

[0014] The disk body is also provided with a plurality of through holes extending along the axial direction of the drive shaft. The plurality of through holes are circumferentially spaced around the axis of the drive shaft and are located close to the outer peripheral edge of the disk body.

[0015] The disc body also has a thickened portion extending along the axis of the drive shaft on the side opposite to the support surface; it also includes a heating component, which is fixed to the thickened portion on the side opposite to the support surface and located on the outer periphery of the support surface.

[0016] A reagent turntable leveling method includes a fixed base and several adjustment mechanisms. The fixed base has a support surface for fixing and supporting the turntable. The adjustment mechanisms are arranged circumferentially around the axis of the drive shaft, so that each adjustment mechanism acts between the turntable and the support surface.

[0017] The disc is rotated and its levelness is checked. Based on the check results, the target position that needs to be adjusted is determined. The adjustment mechanism at the target position is rotated to change the relative distance between the disc and the support surface at the corresponding position. The check and adjustment operations are repeated to make the levelness of the disc reach the preset requirements.

[0018] The axial runout error at various circumferential positions during the rotation of the disk is measured using a dial indicator or a laser displacement sensor to characterize the disk's levelness.

[0019] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In this invention, the fixed base and the drive shaft are coaxially fixedly connected, and the support surface supports and positions the disc, reducing assembly and transmission errors. At the same time, by using the circumferentially distributed adjustment mechanism in cooperation with the support surface, the levelness of the disc can be corrected by changing the local relative distance between the disc and the support surface. This leveling mechanism can control the end face runout of the disc within a set range, effectively solving the problem of turntable tilting caused by installation errors, part size tolerances and form and position tolerances.

[0021] 2. In this invention, a reliable connection can be achieved between the disc body and the fixed seat, and between the fixed seat and the drive shaft. By passing the fixing member through the first fixing hole of the support surface and the second fixing hole of the disc body, relative displacement between the disc body and the fixed seat during rotation is avoided. By inserting the fixing member into the third fixing hole of the fixed seat and pressing it against the drive shaft, the circumferential and axial relative fixation between the fixed seat and the drive shaft is achieved, preventing any impact on transmission accuracy and further ensuring stable rotation of the disc body to match the levelness adjustment effect.

[0022] 3. In this invention, the first limiting part of the fixed seat is fitted with the second limiting part of the first mounting hole of the disc body to achieve circumferential relative fixation between the two; the positioning post on the support surface of the fixed seat passes through the positioning hole of the disc body to limit the radial relative offset between the two; the thickened part of the disc body is partially fitted with the support surface, which not only enhances the support stability, but also improves the structural strength and heat conduction efficiency of the corresponding area of ​​the disc body, providing structural support for the stable operation of the leveling mechanism.

[0023] 4. In this invention, the disc body is provided with through holes to correspond one-to-one with the windows of the reagent tray, so as to avoid the disc body blocking the optical signal and ensure that the detection light reaches the reagent smoothly; and after the end face of the disc body is controlled by the leveling mechanism to reduce the difference between the optical data acquisition holes of the reagent tray; the heating component, together with the NTC temperature sensor and the closed-loop control of the circuit board, can maintain the reagent incubation temperature stably, further ensuring the detection accuracy.

[0024] 5. In this invention, the levelness can be adjusted by a screw-on adjustment mechanism, which can be accurately calibrated with a dial indicator and is simple to operate; the number of the first fixing hole, the second fixing hole and the adjustment mechanism can be flexibly set according to the needs of the disc body, and the overall leveling mechanism is inexpensive; there are no complex components, the manufacturing cost is low and the assembly and debugging are convenient, while effectively solving the problem of turntable tilting caused by the accumulation of various errors, thus improving the practicality and economy of the device.

[0025] 6. In this invention, by rotating the disc and detecting its levelness, and then adjusting the corresponding adjustment mechanism after locating the deviation position, the levelness of the disc can be accurately corrected; the operation is simple, suitable for assembly and maintenance scenarios, and effectively improves leveling efficiency and consistency.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Detailed Implementation

[0037] The present invention will be further described below through specific embodiments.

[0038] See Figures 1 to 8 A reagent turntable device includes a turntable body 10, a driving component 20, a fixed base 30, and several adjusting mechanisms 40. The driving component 20 is provided with a driving shaft 21 to output driving force, and the driving component 20 may be a motor. The fixed base 30 is coaxially fixedly sleeved on the outside of the driving shaft 21, and its outer circumference is integrally formed or fixedly connected with a radially outwardly extending flange 31. The side of the flange 31 opposite to the turntable body 10 serves as a support surface 311. The disc body 10 is coaxially and detachably fixedly sleeved on the fixing base 30. The side of the disc body 10 facing the flange 31 is attached to the support surface 311 of the flange 31, and the support surface 311 provides stable support for the disc body 10. Several adjustment mechanisms 40 are circumferentially spaced around the axis of the drive shaft 21, and each adjustment mechanism 40 is located between the disc body 10 and the support surface. The adjustment mechanism 40 can pass through the area of ​​the disc body 10 corresponding to the flange 31 and cooperate with the support surface 311. By adjusting the adjustment mechanism 40, the relative distance between the disc body 10 and the support surface 311 at the corresponding adjustment position is changed, thereby adjusting the levelness of the disc body 10.

[0039] In this embodiment, the device is coaxially fixedly connected to the drive shaft 21 via the fixed base 30, and the flange 31 supports and positions the disc 10, thus constructing a stable transmission foundation. At the same time, the circumferentially distributed adjustment mechanism 40 and the support surface 311 of the flange 31 cooperate to form a structural design that can adjust the level of the disc 10. By operating the adjustment mechanism 40, the level of the disc 10 can be corrected by changing the local relative distance between the disc 10 and the flange 31.

[0040] The flange 31 has several first fixing holes 32 spaced circumferentially around the axis of the drive shaft 21. Correspondingly, the disc 10 has several second fixing holes 11 in the area corresponding to the flange 31. Each second fixing hole 11 corresponds to and communicates with the first fixing holes 32 on the flange 31. Several fixing members 50 are inserted into the corresponding first fixing holes 32 and second fixing holes 11 to reliably fix the disc 10 and the fixing seat 30, preventing relative displacement during rotation. Before operating the adjustment mechanism 40, the fixing members 50 around the adjustment mechanism 40 are loosened to allow adjustment of the disc 10's levelness via the adjustment mechanism 40.

[0041] Meanwhile, at least one adjustment mechanism 40 is provided between two adjacent second fixing holes 11. It should be noted that the specific number of the first fixing holes 32, the second fixing holes 11, and the adjustment mechanism 40 can be flexibly set according to the size of the disc body 10, load-bearing requirements, and precision adjustment requirements. In the figure, an example is given where there are four first fixing holes 32 and two second fixing holes 11, and two adjustment holes 12 between adjacent first fixing holes 32 and second fixing holes 11.

[0042] The disc body 10 has a plurality of adjustment holes 12 in the area corresponding to the flange 31. The adjustment holes 12 are circumferentially spaced around the axis of the drive shaft 21, and each adjustment hole 12 passes through the disc body 10 along the axial direction of the drive shaft 21, providing a channel for the insertion and movement of the adjustment mechanism 40. The adjustment mechanism 40 is inserted into each adjustment hole 12 in a corresponding manner, and the adjustment mechanism 40 and the adjustment hole 12 are threaded together. The inner wall of the adjustment hole 12 is machined with an internal thread, and the outer periphery of the adjustment mechanism 40 is machined with an external thread that matches the internal thread. Through the meshing of the internal and external threads, the adjustment mechanism 40 can move relative to the adjustment hole 12 along the axial direction of the drive shaft 21 during the screwing operation.

[0043] The end of the adjusting mechanism 40 facing the support surface 311 is the pressing end 41. By turning the adjusting mechanism 40, the pressing end 41 moves with the adjusting mechanism 40 to move away from or abut against the support surface 311, thereby changing the relative distance between the position of the corresponding adjusting hole 12 of the disc 10 and the support surface 311. The adjusting mechanism 40 can be a screw, bolt, washer set, or set screw, etc., which can achieve linear micro-displacement through operation and push or release the support surface 311 with its end. Taking the adjusting mechanism 40 as an example, when the set screw is turned close to the flange 31, the end of the set screw facing the support surface 311 will push the flange 31, causing the disc 10 to be lifted upward at the corresponding position, thereby increasing the relative distance between the disc 10 and the flange 31; when the set screw is turned away from the flange 31, the pushing force between the set screw and the support surface 311 weakens, and the disc 10 can fall back slightly with the retraction of the set screw, thereby reducing the relative distance between the disc 10 and the flange 31. The bidirectional adjustment of the set screw can precisely correct the height of different positions of the disc 10, providing reliable structural support for adjusting the level of the disc 10.

[0044] The disc body 10 has a first mounting hole 13 extending through the axis of the drive shaft 21 in its center. The fixing seat 30 passes through the first mounting hole 13, ensuring that their axes coincide. To prevent circumferential relative displacement between the disc body 10 and the fixing seat 30 during synchronous rotation, at least one radially extending first limiting part 33 is provided on the outer periphery of the fixing seat 30. Correspondingly, at least one second limiting part 14 is provided on the inner wall of the first mounting hole 13. The first limiting part 33 and the second limiting part 14 achieve circumferential relative fixation between the fixing seat 30 and the disc body 10 through the engagement of a protrusion and a groove. For example, the first limiting part 33 can be a radially outward extending protrusion, and the second limiting part 14 can be a radially inward recessed groove, or vice versa. The number of first limiting parts 33 can be one, two, or even more, and the number of second limiting parts 14 corresponds to the number of first limiting parts 33. In the figure, two first limiting parts 33 are shown as an example.

[0045] The fixed base 30 is further provided with a positioning post 34 extending along the axial direction of the drive shaft 21 on the support surface 311, and the positioning post 34 is perpendicular to the support surface 311. Correspondingly, the disc body 10 has a positioning hole 15 on the side opposite to the support surface 311. The diameter of the positioning hole 15 is adapted to the outer diameter of the positioning post 34. The positioning post 34 passes through the corresponding positioning hole 15 along the axial direction of the drive shaft 21, thereby limiting the relative radial offset between the disc body 10 and the fixed base 30. Among them, a radially outward protrusion 37 can be provided on the support surface 311, and the positioning post 34 can be provided on the protrusion 37. The disc body 10 is provided with a groove that adapts to and accommodates the protrusion 37.

[0046] The fixed base 30 is provided with a second mounting hole 35 in the middle, which runs through the axis of the drive shaft 21. The diameter of the second mounting hole 35 is adapted to the outer diameter of the drive shaft 21, so that the drive shaft 21 can pass through along the axis, ensuring the coaxiality of the fixed base 30 and the drive shaft 21. In order to achieve a reliable connection between the fixed base 30 and the drive shaft 21, the fixed base 30 is also provided with at least one third fixing hole 36 that is radially connected to the second mounting hole 35. Each third fixing hole 36 is close to the end of the second mounting hole 35 that is opposite to the support surface 311. A fixed connection between the drive shaft 21 and the fixed seat 30 is achieved by inserting at least one fixing member 50 into the corresponding third fixing hole 36 and pressing it tightly against the drive shaft 21: After the fixed seat 30 is sleeved on the drive shaft 21 at the preset position through the second mounting hole 35, the corresponding fixing member 50 (such as a set screw) is inserted into the third fixing hole 36 and the fixing member 50 is tightened so that its end is pressed tightly against the outer circumferential surface of the drive shaft 21. By utilizing the friction and radial pressure between the fixing member 50 and the drive shaft 21, the fixed seat 30 can be firmly locked on the drive shaft 21, so as to achieve relative fixation of the two in the circumferential and axial directions, and to prevent the fixed seat 30 from being relatively displaced from the drive shaft 21 when the disc body 10 rotates, thus affecting the transmission accuracy.

[0047] The disk body 10 is used to hold a reagent tray, which has a window. The disk body 10 also has several through holes 16 extending along the axis of the drive shaft 21. These through holes 16 are circumferentially spaced around the axis of the drive shaft 21 and located near the outer edge of the disk body 10. These through holes 16 are positioned opposite the windows on the reagent tray. When the reagent tray is placed on the disk body 10, the through holes 16 on the disk body 10 correspond one-to-one with the windows on the reagent tray, preventing the disk body 10 from obstructing the optical signal and ensuring that the detection light can pass smoothly through the through holes 16 and the windows to reach the reagent in the reagent tray.

[0048] A thickened portion 17, integrally formed or fixedly connected to the support surface 311, is also provided on one side of the disc body 10. The thickened portion 17 is thickened by extending along the axis of the drive shaft 21. The thickened portion 17 is located on the outer periphery of the flange 31, that is, the thickened portion 17 avoids the areas of the first mounting hole 13, the adjustment hole 12, and the second fixing hole 11. In addition, the thickened portion 17 is annular, and its inner ring diameter is larger than its outer ring diameter.

[0049] It also includes a heating component 70, which is fixedly installed on the side of the thickened portion 17 facing away from the support surface 311 and is arranged around the outer periphery of the flange 31. This layout design utilizes the solid structure of the thickened portion 17 as a heat conduction medium, so that the heat generated by the heating component 70 can be evenly transferred to the disk body 10 and the reagent tray above it; on the other hand, by confining the heating component 70 to the outer periphery of the flange 31, interference with the transmission structure such as the fixed base 30 and the adjustment mechanism 40 can be avoided, ensuring that the function of the heating component 70 and the rotation function of the turntable do not affect each other.

[0050] The heating assembly 70 includes a heating element 71 and an NTC temperature sensor, which work together to control the temperature of the reagents on the tray 10. The heating element 71 is fixed to the surface of the thickened part 17 (the side facing away from the tray 10) by adhesive. During operation, it transfers heat to the tray 10 through thermal conduction, and then the tray 10 evenly conducts the heat to the reagent tray above, providing a stable incubation temperature environment for the reagent strips or reagent cards in the reagent tray.

[0051] An NTC temperature sensor, acting as a temperature sensing element, is embedded in a pre-set small hole in the disk body 10. Its sensing end is in direct contact with the disk body 10 to monitor the temperature of the disk body 10 in real time. The temperature signal fed back by the NTC temperature sensor can dynamically adjust the working state of the heating element 71 to ensure that the incubation temperature of the reagent strip is always maintained within the preset range.

[0052] In this embodiment, a circuit board 80 for integrating control functions is also included. The circuit board 80 is fixedly mounted on the side of the flange 31 facing away from the disk body 10 by a fastener 50, making full use of the space on the back of the flange 31 to achieve a compact layout. The circuit board 80 establishes electrical connections with the heating assembly 70 and the driving component 20 respectively: on the one hand, it receives the signal feedback from the NTC temperature sensor and outputs control commands to the heating element 71 to regulate the incubation temperature; on the other hand, it outputs drive signals to the driving component 20 to control the rotation speed and start / stop timing of the drive shaft 21.

[0053] In this embodiment, a reagent turntable leveling method is also proposed, which is implemented using the above-mentioned reagent turntable device, including a fixed base 30 and several adjusting mechanisms 40. The fixed base 30 has a radially outwardly extending flange 31 on its outer periphery. The fixed base 30 is coaxially fixedly sleeved on the drive shaft 21 of the drive member 20, and then the disc body 10 is coaxially sleeved on the fixed base 30, so that the support surface 311 of the flange 31 supports the disc body 10. Several adjusting mechanisms 40 are arranged circumferentially around the axis of the drive shaft 21, so that each adjusting mechanism 40 passes through the area of ​​the disc body 10 corresponding to the flange 31 and cooperates with the support surface 311. The disc body 10 is rotated and its levelness is detected. Based on the detection result, the target position that needs to be adjusted is determined. By rotating the adjusting mechanism 40 at the target position, the relative distance between the disc body 10 and the flange 31 at the corresponding position is changed. The detection and adjustment operations are repeatedly performed so that the levelness of the disc body 10 reaches the preset requirement.

[0054] To further improve leveling accuracy and adapt to the requirements of high-precision experimental scenarios, a dial indicator or laser displacement sensor can be used to measure the axial circular runout error at various circumferential positions during disk rotation, thus characterizing the disk's levelness. For example, regarding the calibration of disk levelness using a dial indicator, see [link to documentation]. Figure 9 The specific operation method is as follows:

[0055] Fix the dial indicator 90 on the reference bracket 91 above the disc 10, so that the detection end of the dial indicator 90 is perpendicular to the upper surface of the disc 10 (the detection area near the outer edge); slowly rotate the disc 10 one revolution, read the height deviation value of each position of the disc 10 through the dial indicator 90, determine the highest point with the largest deviation, and adjust the dial of the dial indicator 90 so that the pointer is aligned with the "0" mark.

[0056] Rotate the dial 10 again and observe the change in the dial indicator 90 pointer. Ensure that the pointer reading is always within the set acceptable range (red marking 0-90). If the reading at a certain position exceeds this range, first loosen the fixing part 50 near that position appropriately, then gradually tighten the adjustment mechanism 40 in the corresponding area. By fine-tuning the relative distance between the dial 10 and the flange 31, the dial indicator 90 pointer will return to the acceptable range.

[0057] Repeat the above adjustment process until the dial gauge 90 reading after the disc body 10 has rotated a full circle is stable within the 0-90 range. Finally, tighten all the fasteners 50 (fasteners connecting the disc body 10 and the flange 31) thoroughly to complete the levelness calibration.

[0058] In this invention, the terms "first," "second," and "third," etc., are used only to distinguish similar objects and are not necessarily used to describe a specific order or sequence, nor should they be construed as indicating or implying relative importance. The use of terms such as "upper," "lower," "left," "right," "front," and "rear" to indicate orientation or positional relationships is based on the orientation or positional relationships shown in the accompanying drawings and is only for the convenience of describing the invention, not to indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the scope of protection of this invention.
