Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cleanliness detection and analysis equipment, and particularly relates to a clamping tool for a microscopic scanning sample. Background Art
[0002] In cleanliness detection and analysis equipment, a microscope is needed to microscopically observe thin films or flakes. When soft materials such as thin films and flakes are microscopically scanned and analyzed, without a fixing fixture, the sample is uneven, which easily leads to the inability to piece together and scan the analysis microscopically. Especially for square thin film samples, the existing clamping methods mostly directly use glass slides to press and cover. If the glass slides are relatively thin and light, they cannot ensure flat pressing and covering. Content of the Utility Model
[0003] Aiming at the deficiencies of the existing technology, the main purpose of the utility model is to provide a clamping tool for a microscopic scanning sample that can clamp a square thin film sample, ensure the flatness of the sample, is beneficial to high-definition imaging and piecing together of the sample, has a base point for placing the sample, and ensures the consistency of the scanning area.
[0004] To achieve the above purpose, the utility model provides the following technical solution: A clamping tool for a microscopic scanning sample, including an aluminum alloy bracket, a white substrate laid on the aluminum alloy bracket, and a glass pressed on the white substrate. Both sides of the aluminum alloy bracket are respectively provided with frames. The top of the glass is flush with the frames. Each frame is respectively provided with a plurality of fixing screws that can press and cover the glass. It also includes a U-shaped limiting frame that covers the white substrate and abuts against the end of the glass.
[0005] Preferably, the aluminum alloy bracket includes a bottom plate for supporting the white substrate. One end of the bottom plate has an extension part, and the U-shaped limiting frame is sleeved on the extension part.
[0006] Preferably, the two frames of the aluminum alloy bracket are provided with limiting steps for bearing the glass.
[0007] Preferably, both ends of the U-shaped limiting frame are respectively provided with threaded limiting holes.
[0008] The utility model has the following advantages over the prior art: it can clamp square film samples. When in use, after placing the film on the white substrate, then press the glass on the film and the white substrate, and then fix the glass on the aluminum alloy bracket through the fixing screws arranged on the frame. The white base of this solution uses white materials, which can increase the contrast of the microimaging background pattern and is beneficial to the micro-scanning analysis of film samples. By adopting the glass and the fixing screw locking device, the sample is flattened, which is beneficial to high-definition imaging and stitching of the sample. The position of the U-shaped limiting frame can be adjusted on the white substrate, and the glass abuts against one side of the U-shaped limiting frame, so that a base point can be provided for placing the sample and the consistency of the scanning area can be ensured.
