Description

Technical Field

[0001] The utility model relates to the field of particle image microscope devices, in particular to a particle microscopic image particle size and shape analyzer. Background Art

[0002] In the research and production of powder materials, particle size and shape are key factors in their physical and chemical properties, directly affecting a variety of properties such as fluidity, dispersibility, bulk density, reactivity, and mechanical strength. Therefore, accurate and rapid measurement of particle size and shape is crucial for optimizing production processes, improving product quality, controlling costs, and expanding application areas.

[0003] Traditional methods for measuring particle size and shape rely primarily on screening, sedimentation, and microscopic observation. However, these methods often suffer from limitations such as tediousness, time-consuming operation, and large errors. For example, while screening is simple and direct, it suffers from low measurement accuracy and fails to accurately reflect the true shape of particles. While sedimentation can provide particle size distribution, it is complex and significantly affected by particle shape, density, and the medium used. Traditional microscopic observation requires manual counting and measurement, which is not only inefficient but also difficult to guarantee the accuracy and repeatability of measurement results.

[0004] With advances in science and technology and the development of computer image processing, microscopic image-based particle size and shape measurement methods have gradually demonstrated their unique advantages. This method uses a microscope to magnify a particle sample, captures the particle image with a high-resolution camera, and then automatically analyzes and processes the image using specialized software, allowing for rapid and accurate determination of particle size and shape parameters. Compared to traditional methods, microscopic image-based measurement methods offer advantages such as a high degree of automation, high measurement accuracy, excellent repeatability, and strong adaptability.

[0042] The preferred embodiment of the particle microscopic image particle size and shape analyzer is as follows:

[0043] How Microscopes Work

[0044] This utility model uses a high-magnification objective lens and a high-magnification eyepiece to achieve high-resolution magnification of particle samples. Through the combination of a high-magnification objective lens and a high-magnification eyepiece, the details of the particles can be clearly observed, providing a reliable image basis for subsequent image acquisition and analysis.

[0045] Working principle of orthogonal polarization channel 3 and single polarization channel 4

[0046] Cross-polarized channel 3 and single-polarized channel 4 are key components of the analyzer, providing different illumination conditions for observing the characteristics of particle samples. Cross-polarized channel 3 uses orthogonal polarization to observe the internal structure and texture of particle samples, while single-polarized channel 4 uses single-polarized light to observe the morphology and size of particle samples.

[0047] Camera Interface 9 and Image Acquisition Principle

[0048] Camera ports 9 are provided at the ends of the crossed polarization channels 3 and the single polarization channel 4. These ports 9 are threaded with a high-resolution camera and a binocular camera lens 5. The high-resolution camera is used to capture microscopic images of the particle sample, while the binocular camera lens 5 is used for manual observation and analysis. The mounting arrangement of the camera ports 9 allows for easy replacement and upgrade of camera equipment to accommodate varying measurement requirements. The high-resolution camera can be connected via a data cable to an external image processing device, which can include a computer and dedicated analysis software. The computer receives and processes image data transmitted by the image acquisition device, while the dedicated analysis software automatically identifies particle edges and contours and calculates particle size and shape parameters, including particle size and size distribution.

[0049] Thread structure and sealing design

[0050] Both the cross-polarization channel 3 and the single-polarization channel 4 are connected to the spectrometer base 1 via a threaded structure. This design not only ensures a secure connection but also facilitates disassembly and maintenance. Furthermore, a sealing gasket is provided at the connection to effectively prevent light leakage and dust intrusion, ensuring measurement accuracy and extending the instrument's service life.

[0051] Cover 10

[0052] By arranging a cover plate 10 on the top of the spectrometer seat 1, when the cover plate 10 is removed, the spectrometer seat 1 on the spectrometer seat 1 can be opened, and the spectroscope 7 in the spectrometer chamber 2 can be replaced according to different spectroscopic ratios required during detection.

[0053] Installation of elastic pad and beam splitter 7

[0054] An elastic pad is installed on the inner wall of the spectroscopic chamber 2, and the sides of the spectroscope 7 fit snugly against the pad. This design allows the spectroscope 7 to fit snugly against the inner wall of the spectroscopic chamber 2 during installation, reducing light reflection and scattering on the spectroscope 7, improving light utilization and image quality. Furthermore, the bottom of the spectroscope 7 is perpendicular to the light inlet 8, the top is perpendicular to the orthogonal polarization channel 3, and the sides are aligned with the single polarization channel 4. This layout ensures proper light propagation and distribution.

[0055] Design of binocular camera tube 5

[0056] The binocular camera tube 5 utilizes a high-magnification objective lens and eyepiece 6, allowing the observer to directly observe the microscopic image of the particle sample through the tube. This design not only facilitates manual observation and analysis but also improves the accuracy and reliability of measurement. Furthermore, the high-magnification objective lens and eyepiece 6 allow the observer to more clearly observe the details and characteristics of the particle sample.

[0057] This utility model describes a particle microscopic image particle size and shape analyzer, whose working principle is mainly based on the combination of a microscope and an image acquisition device. The following is an overview of the working principle of the analyzer:

[0058] Microscope system:

[0059] The spectrometer base 1 and its internal spectrometer chamber 2 are the core components of the microscope. The spectrometer 7 installed in the spectrometer chamber 2 can split the light generated by the light source into two paths according to different needs, one path entering the single polarization channel 4 and the other entering the orthogonal polarization channel 3.

[0060] The single polarization channel 4 is installed horizontally on one side of the spectrometer seat 1 and is connected to the spectrometer chamber 2. This channel allows light to pass through in a single polarization direction and is suitable for observing the basic morphology and size of particles.

[0061] The orthogonal polarization channel 3 is vertically mounted on the top of the spectrometer seat 1 and is also connected to the spectrometer chamber 2. Through the orthogonal polarization channel 3, light propagates in orthogonal polarization states, making it easier to observe the internal structure and texture characteristics of the particles.

[0062] The binocular camera lens barrel 5 is arranged on the orthogonal polarization channel 3, and two eyepieces 6 are symmetrically arranged on it, allowing the observer to directly observe the microscopic image of the particles through the eyepieces 6. This design not only facilitates manual observation, but also improves the intuitiveness and accuracy of measurement.

[0063] Image acquisition device:

[0064] High-resolution cameras are located at the ends of the crossed polarization channels 3 and the single polarization channel 4 to capture microscopic images of particles. These cameras can capture detailed features of particles, providing high-quality image data for subsequent particle size and shape analysis.

[0065] The light source is arranged at the bottom of the light inlet 8 to provide stable and uniform lighting conditions for the microscope. Good lighting conditions are the basis for obtaining clear and accurate microscopic images.

[0066] During operation, the particles to be observed are placed above a light source, which provides illumination. The light enters the spectroscopic chamber 2 through the light inlet 8, is divided into two paths by the spectroscope 7, and enters the single polarization channel 4 and the orthogonal polarization channel 3 respectively. The observer can directly observe the microscopic image of the particles through the binocular camera tube 5, while the high-resolution camera is also synchronously collecting image data. According to the needs of observation and analysis, you can choose to use the single polarization channel 4 or the orthogonal polarization channel 3 for observation to obtain particle images under different lighting conditions. Finally, the collected image data is processed and analyzed by image analysis software to obtain the particle size and shape parameters. According to the needs of different particle observations, the light source can be any of the following light sources, including but not limited to visible light (white light) light source, laser light source, electron beam, ultraviolet light, and infrared light.

[0067] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
