Description

Technical Field

[0001] The utility model relates to the field of microscope processing equipment, and in particular to a flattening device for a polarizing microscope. Background Art

[0002] High-quality petrographic samples must meet three criteria: first, they must demonstrate the sample's true structure; second, the results must be reproducible; and third, they must be easily and quickly prepared to provide accurate, timely, and scientifically sound analytical results. Laboratories typically use the Tegramin-30 fully automatic grinding and polishing machine produced by Stell, Germany. By running the equipment through the adjusted steps and parameters, it can achieve automated, efficient, and stable polishing of high-quality single-sided lithographic specimens. With the advancement of technology and the expansion of intelligent equipment, the requirements for petrographic analysis are becoming increasingly stringent. Currently, polarizing microscopes equipped with automated stages can scan large areas of samples and calculate mineral content and particle size. Petrographic sample preparation is a prerequisite for refined petrographic analysis. In such cases, the top and bottom surfaces of petrographic lithographic samples must be perfectly level to meet relevant testing requirements. Otherwise, as the stage moves, the image of the minerals in the microscope becomes blurred, making further measurements impossible.

[0003] The most common way to solve the leveling problem of light sheet samples is to fill the sample with plasticine on a horizontal glass plate, and then press it several times with a manual flattener. The problem is that the light sheet sample cannot be completely level under the microscope due to uneven manual force. During the test, as the sample stage moves, the morphology will gradually become blurred, resulting in a small scanning area and an inability to represent the true information of the entire sample. At present, conventional domestic laboratories are generally equipped with manual flatteners because most cases do not require analysis of a large field of view. Polarized microscopes equipped with automatic stages are often rarely used due to the lack of suitable flatteners. Summary of the Invention

[0004] To address the aforementioned issue of uneven force applied by manual applanators, which can result in the light sheet sample not being completely level under the microscope, a polarizing microscope applanator is provided. This utility model designs a mechanical applanator that uses a uniform spring to apply force evenly and is equipped with a buffer module, resolving the problem of uneven force applied to the light sheet sample. Light sheet samples prepared using this device achieve completely level upper and lower surfaces, significantly improving the utilization rate of the polarizing microscope's automatic stage.

[0005] The technical means adopted by this utility model are as follows:

[0006] A flattener for a polarizing microscope, comprising: a movable bolt, a compression spring, a movable module, a flattening module, and a fixed support;

[0007] The movable bolt is used to place the optical sheet under the flattening module and screw it to the nut cap just below to prevent the optical sheet from shaking and becoming unlevel.

[0008] The compression spring is always in a compressed state to keep the optical sheet under uniform force;

[0009] The movable module is an aluminum cylindrical block, which is mounted on a spring and can move up and down;

[0010] The flattening module is made of plastic, with a groove in the center of the upper surface connected to the compression rod, and a completely flat lower surface for contacting the smooth surface of the sample.

[0011] Furthermore, the fixed support is made of magnesium-aluminum alloy and is fixed to the horizontal support by bolts at the top and bottom to keep the upper and lower horizontal supports completely level.

[0012] Furthermore, when the movable module moves upward, it drives the nut under the movable bolt to move upward, and the movable stroke is the height of the inner diameter of the cylindrical cover of the movable bolt.

[0013] Furthermore, the top of the movable bolt is provided with anti-slip grooves, which facilitates the user's twisting operation and prevents the hand from slipping.

[0014] Furthermore, positioning marks are provided on the flattener horizontal surface to facilitate users to accurately place the light sheet sample and ensure that the placement position is consistent each time.

[0015] Furthermore, a pressure sensor is installed on the horizontal surface of the flattening device, which can monitor the pressure exerted on the optical sheet during the flattening process in real time and display the pressure value on the display screen.

[0016] Due to the adoption of the above technical solution, compared with the prior art, the present invention has the following advantages:

[0017] 1. The utility model provides a flattening device for polarizing microscope, which applies uniform pressure to the light sheet by compressing the spring, ensuring that the light sheet is evenly stressed during the flattening process, effectively improving the flatness of the light sheet, and providing clearer and more accurate images for polarizing microscope observation.

[0018] 2. The utility model provides a flattener for a polarizing microscope. The movable bolt can be screwed to the nut cap just below when the light sheet is placed under the flattening module to prevent shaking caused by external factors, thereby ensuring the stability of the light sheet during the flattening process and improving the flattening effect.

[0019] 3. The utility model provides a flattening device for polarizing microscopes. The flattening module is made of plastic to avoid damage to the light sheet. The fixed support is made of magnesium-aluminum alloy, which has high strength and good stability, ensuring that the upper and lower horizontal supports are always in a completely horizontal state, providing a reliable foundation for flattening the light sheet.

[0020] 4. The utility model provides a flattener for a polarizing microscope. The movable module is an aluminum cylindrical block, which is convenient for moving up and down on the spring. The top of the movable bolt is provided with anti-slip grooves, and positioning marks are provided on the horizontal platform. These designs improve the convenience of operation, enable users to quickly and accurately perform light sheet flattening operations, and improve work efficiency.

[0021] Based on the above reasons, the utility model can be promoted in the field of microscope processing equipment. BRIEF DESCRIPTION OF THE DRAWINGS
