All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0029] It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.
[0030] It should also be understood that the terminology used in this specification of embodiments of the present invention is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of the present invention. As used in this specification of embodiments of the present invention and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.
[0031] See Figure 1 This utility model provides a fiber and particle observation device. The device includes a carrying component 1, an optical mechanism 2, a rotating mechanism, and a dark-field illumination mechanism 4. The specific details of each component are as follows:
[0032] In this embodiment, the rotating mechanism is located on one side of the dark field illumination mechanism 4, and the carrying component 1 is located on the rotating mechanism. The rotating mechanism can drive the carrying component 1 to rotate. The carrying component 1 is provided with a light-transmitting part 11, which is located above the dark field illumination mechanism 4. The optical mechanism 2 is located above the dark field illumination mechanism 4.
[0033] Specifically, the sample carrier 1, as the key component carrying the particle sample to be observed, is specially designed with a light-transmitting part 11 and is mounted on the rotating mechanism to ensure that the sample can be illuminated and observed from all directions during the observation process. The optical mechanism 2, located above the dark-field illumination mechanism 4, is responsible for capturing the subtle features of the particles and converting them into data signals that can be analyzed; it is the "eye" for achieving precise observation. The rotating mechanism is set close to the dark-field illumination mechanism 4, which can drive the sample carrier 1 to rotate smoothly, allowing the sample to be illuminated and observed from different angles, avoiding blind spots and comprehensively acquiring particle information. The dark-field illumination mechanism 4 creates a unique dark-field environment for the entire observation system. Through clever light processing, the particles are clearly visible against the dark background, highlighting their edges, contours, and other detailed features.
[0034] The rotating mechanism drives the carrier component 1 to rotate, and the optical mechanism 2 collects, observes and records the particles at the light-transmitting part 11 of the carrier component 1. A stable dark field is formed below the light-transmitting part 11 by the dark field illumination mechanism 4, so that the optical mechanism 2 can clearly observe the edge, outline and refractive index gradient of the sample against a dark background. This fiber and particle observation device can efficiently and accurately realize the observation and analysis of various particles.
[0035] See also Figure 1 In this embodiment, the fiber and particle observation device further includes a housing 5, the housing 5 having a groove 51, the dark field illumination mechanism 4 being disposed in the groove 51, and the optical mechanism 2 and the rotating mechanism being disposed on the housing 5 respectively.
[0036] Specifically, the housing 5 serves to protect the internal components and provide a stable support structure. The housing 5 features a carefully designed groove 51 into which the dark field illumination mechanism 4 is precisely embedded, saving space and effectively shielding against external stray light interference. The optical mechanism 2 and the rotating mechanism are mounted on the housing 5 in a rational layout, ensuring the relative positional accuracy between the components and guaranteeing the stability of the system operation.
[0037] In another embodiment, the housing 5 is further provided with a cavity on one side of the groove 51, the cavity being able to accommodate the rotating mechanism.
[0038] Furthermore, the dark field lighting mechanism 4 includes a light-emitting module 41, a light-uniforming component 42, a first light-reducing component 43, a second light-reducing component 44, and a light-transmitting component 45; the light-emitting module 41, the light-uniforming component 42, the first light-reducing component 43, and the second light-reducing component 44 are respectively located in the groove 51, and the light-transmitting component 45 covers the opening of the groove 51; the first light-reducing component 43 is located at the bottom of the groove 51, the light-uniforming component 42 is located above the first light-reducing component 43, the light-emitting module 41 is connected to the light-uniforming component 42, and the second light-reducing component 44 is located on the light-uniforming component 42.
[0039] Specifically, the light-emitting module 41 serves as the light source, providing initial light for the entire dark-field illumination. Its light-emitting characteristics are carefully calibrated to meet the stringent requirements of fiber and particle observation for light intensity and stability. For example, the light from the light-emitting module 41 illuminates the light-diffusing component 42. The light-diffusing component 42 is positioned close to the light-emitting module 41 and is used to evenly disperse the light emitted by the light-emitting module 41, avoiding local over-brightness or under-brightness caused by concentrated light, ensuring uniform illumination on the sample surface, and laying the foundation for accurate observation. The first light-reducing component 43 is located at the bottom of the groove 51 and can effectively absorb or reflect excess light, reducing the initial intensity of the light and preventing strong light from obscuring the details of fiber and particle observation. The second light-reducing component 44 is arranged on the light-diffusing component 42 to further fine-tune the light intensity to achieve the most suitable brightness level for particle imaging. The light-transmitting component 45 covers the opening of the groove 51, allowing the processed light to pass through smoothly and blocking external dust, moisture, and other impurities from entering the dark-field illumination mechanism 4, ensuring the purity of the optical environment.
[0040] In specific implementation, the light-emitting module 41 includes multiple LEDs surrounding the light-diffusing component 42. The light-diffusing component 42 has a cylindrical structure, with multiple LEDs distributed around its outer wall. The first light-reducing component 43 includes a light-absorbing plate, such as a circular black plate, installed below the cylindrical light-diffusing component 42. The second light-reducing component 44 includes a light-absorbing cylinder, such as a black cylinder, installed on the inner wall of the cylindrical light-diffusing component 42. The light-transmitting component 45 includes a light-transmitting plane mirror, which covers the opening of the groove 51, enclosing the light-emitting module 41, the light-diffusing component 42, the first light-reducing component 43, and the second light-reducing component 44 inside the groove 51, blocking external dust, moisture, and other impurities.
[0041] To ensure the stable operation of the light-emitting module 41, the system is also equipped with an additional heat dissipation module 6, which is connected to both the light-emitting module 41 and the housing 5. It can dissipate the heat generated by the light-emitting module 41 during operation in a timely manner, preventing problems such as decreased luminous efficiency, deteriorated light stability, or even damage to the light-emitting elements due to overheating, thus extending the system's service life.
[0042] Furthermore, the length of the second light-reducing member 44 is less than the length of the light-uniforming member 42, and the top of the second light-reducing member 44 is flush with the top of the light-uniforming member 42.
[0043] In this embodiment, the length of the second light-reducing member 44 refers to the distance from the bottom to the top of the second light-reducing member 44, and the length of the light-diffusing member 42 refers to the distance from the bottom to the top of the light-diffusing member 42. Understandably, the second light-reducing member 44 is mounted near the top of the light-diffusing member 42. In another embodiment, the bottom height of the second light-reducing member 44 is greater than the top height of the light-emitting module 41.
[0044] Furthermore, the fiber and particle observation device also includes a heat dissipation module 6, which is connected to the light-emitting module 41 and the housing 5 respectively.
[0045] Specifically, the heat dissipation module 6 includes silicone and thermal grease, which are installed between the light-emitting module 41 and the housing 5 to improve the heat transfer efficiency between the light-emitting module 41 and the housing 5, thereby improving the heat dissipation effect.
[0046] Furthermore, the fiber and particle observation device also includes a moving mechanism 7, which is connected to the optical mechanism 2 and the housing 5 respectively.
[0047] Specifically, the moving mechanism 7 is used to drive the optical mechanism 2 to move up and down, so as to adjust the height of the optical mechanism 2.
[0048] Furthermore, the moving mechanism 7 includes a support member 71 and a locking member 72. The optical mechanism 2 is disposed on the locking member 72, the locking member 72 is disposed on the support member 71, and the support member 71 is disposed on the housing 5.
[0049] Specifically, the support component 71 includes a vertical pole, and the locking component 72 includes a sleeve and a knob. The sleeve is fitted onto the vertical pole and is also connected to the optical mechanism 2. The knob passes through a bolt hole on the sleeve and is screwed into the sleeve to fix the sleeve at a certain height on the vertical pole. By screwing the knob out of the sleeve, the sleeve can move up and down on the vertical pole. This moving mechanism 7 has a simple structure and low cost.
[0050] Furthermore, the moving mechanism 7 also includes a focusing component 73, which is disposed on the locking component 72, and the optical mechanism 2 is disposed on the focusing component 73.
[0051] Specifically, the focusing component 73 and the locking component 72 are slidably connected by a toothed groove. The focusing component 73 can slide up and down on the locking component 72, thereby driving the optical mechanism 2 to move up and down, so as to realize the focusing function of the optical mechanism 2.
[0052] Furthermore, the rotating mechanism includes a motor 31 and a transmission component 32. The transmission component 32 is connected to the motor 31 and the load component 1 respectively. The motor 31 is on one side of the dark field lighting mechanism 4, and the transmission component 32 is above the motor 31.
[0053] Specifically, the transmission component 32 includes gear transmission, chain transmission, and belt transmission. In this embodiment, the transmission mechanism is connected to the shaft of the motor 31 and the load component 1, respectively. After the motor 31 is powered on, it drives the transmission component 32, which in turn drives the load component 1 to rotate.
[0054] Furthermore, the transmission component 32 includes an internal gear ring 321 and a gear 322. The gear 322 is mounted on the motor 31, and the load-carrying component 1 is mounted on the internal gear ring 321. The internal gear ring 321 meshes with the gear 322.
[0055] In this embodiment, the internal gear ring 321 meshes with the gear 322 to form an internal transmission connection. The carrying component 1 is above the internal gear ring 321. The gear 322 is connected to the shaft of the motor 31. The motor 31 is fixed on the housing 5. After being powered on, it drives the gear 322 to rotate. The gear 322 meshes with the internal gear ring 321, thereby driving the internal gear ring 321 and the carrying component 1 on the internal gear ring 321 to rotate.
[0056] Furthermore, the optical mechanism 2 includes a video acquisition module 21 and a microscope 22, the video acquisition module 21 being connected to the microscope 22 and located above the microscope 22.
[0057] Specifically, the video acquisition module 21 includes a camera for image information observed by the microscope 22. The microscope 22 includes an eyepiece and an objective lens. In this embodiment, the eyepiece of the microscope 22 is above the objective lens. The microscope 22 is used to observe particles on the carrier component 1.
[0058] The procedure for using this fiber and particle observation device is as follows:
[0059] First, prepare an appropriate amount of the nanomaterial microparticle suspension. Use a pipette to draw up a certain amount of the suspension and slowly drop it into the light-transmitting part 11 of the carrier component 1. By gently shaking the carrier component 1 or using a micro oscillator, ensure that the microparticles are evenly dispersed in the suspension to avoid agglomeration.
[0060] Next, the system power is turned on, and the light-emitting module 41 in the dark field illumination mechanism 4 lights up. The emitted light is homogenized by the light-uniforming component 42 and its intensity is adjusted by the first light-reducing component 43 and the second light-reducing component 44. It then passes through the light-transmitting component 45 to form a stable dark field below the carrier component 1. At this time, by observing the light intensity monitoring instrument (if any) connected to the dark field illumination mechanism 4, it is ensured that the light intensity is within the preset appropriate range for fiber and particle observation.
[0061] Next, the motor 31 of the rotating mechanism starts, driving the gear 322 to rotate, which in turn drives the internal gear ring 321 and the carrier component 1 fixed on it to rotate slowly. The rotation speed is preset according to the characteristics of the particles and the observation requirements, and is generally controlled at 1-5 revolutions per minute to ensure that the particles can be fully illuminated and observed from different angles.
[0062] Then, the microscope 22 of the optical mechanism 2 magnifies the particles under illumination, and the video acquisition module 21 acquires images at a rate of 30 frames per second (the frame rate can be adjusted according to actual needs) and transmits them to the computer in real time via a data cable. The professional image analysis software on the computer starts up, processes the incoming images in real time, identifies the particle outlines, measures their size, and counts parameters such as particle number and distribution density.
[0063] Finally, after the observation is completed, turn off the system power, carefully remove the sample carrier 1, and clean its light-transmitting part 11 with a cleaning solvent to remove any residual particulate samples for future use. Simultaneously, perform a simple external cleaning of the entire system, check that all components are functioning properly, and if necessary, perform dust cleaning and other maintenance work on the heat dissipation module 6 to ensure the system is always in good operating condition.
