Description

Technical Field

[0001] The utility model relates to the technical field of particle analysis and detection equipment, in particular to a flux automatic sampling and acquisition module of a particle analyzer. Background Art

[0002] The working principle of a particle analyzer is mainly based on optical, electrical or mechanical particle counting methods to determine the number of tiny particles in a substance. It measures and analyzes specific properties of particles, such as scattered light intensity, resistance change or weight, to obtain information such as the number, size distribution, and concentration of particles. In the biomedical field, particle analyzers can be used to study nano-scale particles such as biological molecules, viruses and bacteria, which helps to gain a deeper understanding of the operating mechanisms of biological systems.

[0003] Existing collection methods mostly use manual single-tube sampling or disk-rotating automated sampling. The operation of throughput automated sampling requires the cooperation of high-precision movement of X- and Y-axis stepper motors. Currently, ordinary throughput automated sampling solutions cannot achieve precise speed regulation of the stepper motor and real-time monitoring of the stop position. Utility Model Content

[0004] The present invention aims to solve the problems existing in the prior art and provides the following technical solutions:

[0005] A flux automated sampling and acquisition module for a particle analyzer comprises an X-axis translation stage mounting base plate and a Y-axis translation stage mounting base plate, the X-axis translation stage mounting base plate being placed perpendicular to the Y-axis translation stage mounting base plate, X linear guide rails being provided on both sides of the surface of the X-axis translation stage mounting base plate, Y linear guide rails being slidably connected on both sides of the X linear guide rails, a closed-loop stepping motor being fixedly mounted on one end of the X-axis translation stage mounting base plate, an idler shaft being fixedly mounted on the other end of the X-axis translation stage mounting base plate, an idler shaft being sleeved on the outside of the idler shaft, a symmetrical X synchronous belt being movably arranged between the closed-loop stepping motor and the idler wheel, a synchronous wheel being fixedly mounted on one end of the Y-axis translation stage mounting base plate, a test tube rack base plate being fixedly mounted on the other end of the Y linear guide rail, a Y synchronous belt being movably connected to the outside of the synchronous wheel, and the Y synchronous belt driving the test tube rack base plate to move synchronously.

[0007] As an improvement of the above technical solution, a stepper motor mounting seat is fixedly mounted on one end of the X-axis translation stage mounting base, and the closed-loop stepper motor is fixedly mounted on the upper part of the stepper motor mounting seat.

[0008] As an improvement of the above technical solution, a light shielding plate is provided on one side of the bottom of the test tube rack base plate, and a test tube rack is fixedly installed on the upper part of the test tube rack base plate.

[0009] As an improvement to the above technical solution, a detachable support frame is fixedly installed on the upper part of the X-synchronous belt and the Y-synchronous belt, and the X-synchronous belt and the Y-synchronous belt are engaged with an engaging connecting block. The tops of the two sets of engaging connecting blocks are respectively installed with the Y-axis translation stage mounting base plate and the test tube rack base plate.

[0010] Beneficial effects of the utility model:

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] See also Figure 1-3 , the utility model provides a technical solution:

[0020] A particle analyzer flux automated sampling and acquisition module includes an X-axis translation stage mounting base plate 1 and a Y-axis translation stage mounting base plate 11. The X-axis translation stage mounting base plate 1 and the Y-axis translation stage mounting base plate 11 are placed vertically. X-axis translation stage mounting base plate 1 is provided with X-linear guide rails 2 on both sides of the surface of the X-axis translation stage mounting base plate 1. Y-linear guide rails 12 are slidably connected to both sides of the X-linear guide rails 2. A closed-loop stepping motor 5 is fixedly mounted on one end of the X-axis translation stage mounting base plate 1, an idler shaft 3 is fixedly mounted on the other end of the X-axis translation stage mounting base plate 1, an idler shaft 3 is externally sleeved with an idler wheel 4, a symmetrical X-synchronous belt 8 is movably arranged between the closed-loop stepping motor 5 and the idler wheel 4, a synchronous wheel 6 is fixedly mounted on one end of the Y-axis translation stage mounting base plate 11, and a test tube rack base plate 14 is fixedly mounted on the other end of the Y-linear guide rail 12. The synchronous wheel 6 is externally movably connected to a Y-synchronous belt 13, and the Y-synchronous belt 13 drives the test tube rack base plate 14 to move synchronously.

[0021] In this embodiment, the X-axis translation stage mounting base plate 1 carries all components in the X-axis direction, and the Y-axis translation stage mounting base plate 11 carries components in the Y-axis direction; the X linear guide rails 2 are mounted on both sides of the surface of the X-axis translation stage mounting base plate 1 to provide a stable sliding track for the Y-axis translation stage, and the Y linear guide rails 12 are slidably connected to the X linear guide rails 2 to allow the test tube rack base plate 14 to move in the Y-axis direction, and the closed-loop stepper motor 5 is used to drive the movement in the X-axis direction; the idler wheel 4 is sleeved on the idler wheel shaft 3 and is used in conjunction with the closed-loop stepper motor 5 and the X synchronous belt 8 to realize power transmission. The X synchronous belt 8 connects the closed-loop stepper motor 5 and the idler wheel 4. When the motor rotates, the Y-axis translation stage is driven to move in the X-axis direction through the synchronous belt. The synchronous wheel 6 is used to drive the movement in the Y-axis direction. The Y synchronous belt 13 is movably connected to the synchronous wheel 6 and drives the test tube rack base plate 14 to move synchronously in the Y-axis direction. The test tube rack base plate 14 is installed at the other end of the Y linear guide 12 to carry the test tube rack 17. The use of the closed-loop stepper motor 5 ensures precise motion control in the X-axis direction. By combining the X-synchronous belt 8 and the idler pulley 4, power can be effectively transmitted and errors can be reduced. The closed-loop control can monitor the operating status of the motor in real time and quickly respond to any abnormal situation through the error alarm mechanism, thereby greatly improving the fault tolerance rate. The closed-loop system can provide real-time position information of the motor movement, which is crucial to ensuring the precise position of the test tube rack base plate 14 and avoiding sample collection errors caused by movement dislocation. The idler pulley 4 is used as a driven power component in conjunction with the closed-loop stepper motor 5 and the X-synchronous belt 8 to effectively realize power transmission and conversion, thereby improving the overall efficiency of the system. The X-axis translation stage, the Y-axis translation stage and the synchronous belt drive method are very compact in structural design, which greatly saves space.

[0022] The movement in the X-axis direction is as follows: when the closed-loop stepper motor 5 is started, it transmits power to the Y-axis translation stage through the X-synchronous belt 8, causing it to move in the X-axis direction along the X-linear guide rail 2.

[0023] The Y-axis movement is as follows: by cooperating with the synchronous wheel 6 and the Y synchronous belt 13, the test tube rack base plate 14 can be moved in the Y-axis direction. By combining the movement of the X-axis and the Y-axis, the test tube rack base plate 14 can be accurately positioned on the two-dimensional plane.

[0024] Specifically, one side of the X synchronous belt 8 is movably connected to a synchronous belt pressure plate connecting plate 9, and a synchronous belt pressure plate 10 is provided on one side of the synchronous belt pressure plate connecting plate 9, and the synchronous belt pressure plate 10 is placed between the X synchronous belts 8.

[0025] In this embodiment, the synchronous belt pressure plate connecting plate 9 connects the synchronous belt pressure plate 10 and the X-axis translation stage mounting base 1. Its main function is to provide a stable mounting point for the synchronous belt pressure plate 10 to ensure that the synchronous belt pressure plate 10 can effectively apply pressure to the X-synchronous belt 8. The synchronous belt pressure plate 10 is located between the X-synchronous belts 8 and is fixed in an appropriate position by the synchronous belt pressure plate connecting plate 9. Its main function is to provide additional tensioning force to ensure that the X-synchronous belt 8 maintains appropriate tightness during operation, thereby preventing slipping or loosening and ensuring transmission efficiency and accuracy.

[0026] Specifically, a stepper motor mounting seat 7 is fixedly mounted on one end of the X-axis translation stage mounting base 1 , and the closed-loop stepper motor 5 is fixedly mounted on the upper portion of the stepper motor mounting seat 7 .

[0027] In this embodiment, the stepper motor mounting base 7 is an important component connecting the closed-loop stepper motor 5 and the X-axis translation stage mounting base 1. The stepper motor mounting base 7 provides a stable mounting platform for the closed-loop stepper motor 5, ensuring that the motor can stably transmit power during operation, reduce vibration and offset, and thus improve the stability and accuracy of the system. The stepper motor mounting base 7 has matching fixing holes or mounting grooves with the X-axis translation stage mounting base 1 so that it can be firmly fixed to the base plate by bolts or other fasteners.

[0028] Specifically, a photoelectric switch 16 is provided on one side of the Y-axis translation stage mounting base 11 .

[0029] In this embodiment, the photoelectric switch 16 can detect the position of the test tube rack bottom plate 14 in the Y-axis direction, and trigger the photoelectric switch 16 to be used as the start and stop zero point.

[0030] Specifically, a light shielding plate 15 is provided on one side of the bottom of the test tube rack base plate 14 , and a test tube rack 17 is fixedly installed on the upper part of the test tube rack base plate 14 .

[0031] In this embodiment, the test tube rack base plate 14 is an important component of the Y-axis translation stage, which is installed at the other end of the Y linear guide rail 12 and is used to carry the test tube rack 17 .

[0032] Specifically, a detachable support frame 18 is fixedly installed on the upper part of the X synchronous belt 8 and the Y synchronous belt 13, and the X synchronous belt 8 and the Y synchronous belt 13 are engaged with an engaging connecting block 19. The top of the two sets of engaging connecting blocks 19 are respectively installed with the Y-axis translation stage mounting base plate 11 and the test tube rack base plate 14.

[0033] In this embodiment, the meshing connection blocks 19 transmit power by engaging with the synchronous belt, thereby driving the movement of the Y-axis translation stage mounting base 11 and the test tube rack base 14. This ensures that the bases can move smoothly along the predetermined path, while also providing higher precision and reliability for the system. The tops of the two sets of meshing connection blocks 19 are connected to the Y-axis translation stage mounting base 11 and the test tube rack base 14, respectively. This connection ensures that the test tube rack base 14 can move accurately with the movement of the synchronous belt. By adjusting the position and angle of the meshing connection blocks 19, the movement trajectory and speed of the test tube rack base 14 can be precisely controlled to meet different experimental or production requirements.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
