Abstract
Description
Technical Field
[0001] This utility model relates to the field of materials processing technology, and in particular to a sample device for fixed thickness and reduced wear. Background Technology
[0002] In the process of materials science research and analysis, it is inevitable to grind metallographic samples to observe the microstructure and properties of metallic materials. Sometimes it is even necessary to grind TEM samples with a thickness of less than 100 μm. In some special analyses, it is also necessary to grind and polish the samples to a controllable thickness. For example, in the process of semiconductor failure analysis, it is often necessary to grind to a specified thickness or a specified position.
[0003] Existing metallographic polishing machines are used to achieve smooth polishing of materials. However, under special requirements, such as in semiconductor failure analysis, it is not possible to perform polishing with controllable thickness. Manual polishing cannot provide intuitive and stable control over the thickness of the material, and neither method can provide timely feedback on whether the material has been polished to the design size, which may result in under-polishing or over-polishing.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0028] Example 1, referring to Figures 1-4 This is the first embodiment of the present invention, which provides a fixed-thickness, wear-reducing sample device, including a transmission assembly 100, a connecting shell 101, and a sleeve 102 fixed to the inner surface of the connecting shell 101; and,
[0029] The rotating assembly 300 includes a linkage shaft 304 movably connected to the sleeve 102, a transmission rod 400 connected to the bottom of the linkage shaft 304, and a fixing assembly 500 connected to the bottom of the transmission rod 400; wherein,
[0030] When the linkage shaft 304 rotates, the transmission rod 400 drives the fixed component 500 to move up and down.
[0031] The bottom of the connecting shell 101 is connected to a fixing seat 201, and the lower end of the fixing seat 201 is connected to a fixing screw 203 by a thread.
[0032] The fixing screw 203 allows the fixing base 201 to be easily removed, making it convenient for the user.
[0033] The upper end of the fixing screw 203 is connected to the connecting shell 101 by threads.
[0034] The mounting base 201 can be easily removed to facilitate the replacement of the ceramic grinding block 204 at the bottom.
[0035] A ratchet bar 301 is fixed to the upper end of the linkage shaft 304, and an end cap 302 is fixed to the edge of the ratchet bar 301.
[0036] The ratchet lever 301 can easily drive the end cap 302 to rotate, thereby adjusting the height of the fixing component 500.
[0037] A ruler ring 303 is fixed to the edge of the end cap 302, and the outer surface of the ruler ring 303 is provided with a scale.
[0038] The ruler 303 can record the distance of rotation, making it convenient to control the vertical movement height of the fixed component 500.
[0039] A ceramic grinding block 204 is fixed to the bottom of the mounting base 201.
[0040] Ceramic grinding block 204 can leave marks on sandpaper, thus indicating the degree of polishing of the sample.
[0041] Usage: Measure the sample thickness d0; fix the sample to the fixing component 500 using adhesive or wax; rotate the ratchet lever 301, which drives the transmission rod 400 to move via the thread on the surface of the linkage shaft 304. The movement of the transmission rod 400 causes the bottom fixing component 500 to move upward, allowing the sample to enter the device. The bottom surface of the sample should not protrude beyond the end face of the ceramic grinding block 204. Place the device on a flat surface. The ratchet lever 301 has a torque ratchet inside. When the torque is too high, the ratchet lever 301 will spin freely and will not be able to drive the linkage shaft 304 to rotate. Rotating the ratchet lever 301 causes the bottom surface of the sample to move towards the end face of the ceramic grinding block 204 until the ratchet lever 301 rotates due to excessive torque. During the large idle rotation, the bottom surface of the sample contacts the plane. The position where the connecting shell 101 contacts the ruler 303 has a vertical scale. Read the value of the scale of the ruler 303 and the connecting shell 101 at this time and record it as d1. Pick up the device and rotate the ratchet rod 301 so that the bottom surface of the sample extends out of the ceramic grinding block 204. Read the value of the scale of the ruler 303 and the connecting shell 101 until d2, and make d2-d1 the thickness to be reduced. Hold the device and put the bottom surface of the sample in contact with the sandpaper, and polish the sample in a figure-eight pattern. Initially, the sample only contacts the sandpaper and one grinding mark can be seen. When the ceramic grinding block 204 contacts the sandpaper, there are five grinding marks on the surface of the sandpaper, indicating that the specified thickness has been reduced.
[0042] Example 2, refer to Figures 1-4 This is the second embodiment of the present invention, which differs from the previous embodiment in that it also includes,
[0043] The fixing component 500 includes a fixing block 503, and the fixing block 503 has a connecting groove 501 inside.
[0044] The connecting groove 501 facilitates the connection of the transmission rod 400.
[0045] A transmission rod 400 is inserted into the inside of the connecting groove 501, and a positioning wavelet 502 is threadedly connected to the surface of the fixing block 503.
[0046] The positioning wavelet 502 can fix the transmission rod 400, thereby facilitating the removal of the fixing component 500.
[0047] Usage process: Rotate the positioning wave 502, and the fixing block 503 will be removed from the transmission rod 400. After connecting the surface of the fixing block 503 to the sample, the fixing block and the transmission rod 400 are connected by the positioning wave 502.
[0048] Example 3, referring to Figures 1-4 This is the third embodiment of the present invention, which differs from the previous embodiment in that it also includes,
[0049] The bottom of the fixing base 201 is connected to the fixing screw tube 202 by a thread, and the upper end of the connecting shell 101 is connected to the set screw 103 by a thread.
[0050] The set screw 103 can press the end cover 302, thereby preventing the end cover 302 from rotating.
[0051] The connecting shell 101 has a through groove inside, and the set screw 103 and the fixing screw tube 202 are located inside the through groove.
[0052] The screwdriver is inserted into the fixing screw tube 202 to facilitate tightening the set screw 103.
[0053] Usage: The fixed screw tube 202 is hollow inside. Insert a screwdriver into the fixed screw tube 202 and turn the set screw 103. The set screw 103 will move upward and press the end cover 302. The end cover 302 will not be able to rotate relative to the connecting shell 101, ensuring that the height of the fixed component 500 does not change during grinding.
