[0001] This utility model relates to the field of electron microscope sample preparation equipment, and in particular to an adjustable-angle electron microscope sample auxiliary embedding device. Background Technology

[0002] Sample embedding is a crucial step in electron microscopy sample preparation, primarily used to fix biological tissues or cellular structures, providing stable support for subsequent microscopic observation. During electron microscopy sample preparation, embedding directly affects the observation results. Traditional electron microscopy sample embedding devices have limitations in angle adjustment, mostly only allowing for fixed-angle embedding. They cannot flexibly adjust the angle according to the sample shape and embedding requirements. The delivery and control of embedding material are also not precise enough, easily leading to waste, insufficient embedding, and uneven or inaccurate embedding, affecting subsequent electron microscopy observation and embedding quality. Therefore, this application proposes an adjustable-angle electron microscopy sample embedding auxiliary device. Utility Model Content

The outer walls of the two cross frames are slidably fitted with sliding sleeves.

[0009] Optionally, the multiple sliding sleeves are grouped in pairs, and one side of each of the multiple groups of sliding sleeves is fixedly connected to a side telescopic sliding rod, and one end of each of the multiple side telescopic sliding rods is sleeved inside the sleeve rod.

[0025] Example

[0026] like Figure 1 and Figure 2 As shown, this utility model proposes an adjustable-angle electron microscope sample-assisted embedding device, including a transmission base 1 and an adjustment mechanism disposed at the top of the transmission base 1. The adjustment mechanism includes a drive motor 2 disposed on one side of the transmission base 1. The output end of the drive motor 2 is drivenly connected to a threaded rod 3. The outer wall of the threaded rod 3 is threadedly connected to a transmission base 4. The top end of the transmission base 4 is fixedly connected to a top support plate 5. The top end of the top support plate 5 is fixedly connected to two electric telescopic rods 6. The transmission base 1 is made of high-strength alloy material and serves as the basic support for the entire device, providing an installation platform for the adjustment mechanism and the embedding mechanism. The drive motor 2 disposed on one side of the transmission base 1 is a servo motor, providing power to the adjustment mechanism. The power unit has a threaded rod 3 connected to its output end, and a transmission seat 4 connected to its outer wall by threads. The transmission seat 4 is made of the same material as the transmission seat 1. A top support plate 5 is fixedly connected to its top end. The top support plate 5 is made of metal sheet and has good load-bearing capacity. When the drive motor 2 works, it drives the threaded rod 3 to rotate. Under the action of threaded transmission, the transmission seat 4 moves along the axial direction of the threaded rod 3, thereby driving the top support plate 5 to move and realize the horizontal position adjustment of the sample. Two electric telescopic rods 6 are fixedly connected to the top of the top support plate 5. The extension and retraction of the electric telescopic rods 6 can drive the positioning mechanism to move up and down, realize the vertical height adjustment of the sample, and then cooperate with the angle adjustment to meet different embedding requirements.

[0027] Furthermore, such as Figure 2 and Figure 4As shown, a positioning mechanism is provided at the top of the two electric telescopic rods 6. The positioning mechanism includes a support frame 7 fixed to the top of the two electric telescopic rods 6. A perforated plate 8 is fixedly connected to the center of the top of the support frame 7. Top connecting blocks 11 are fixedly connected to both sides of the outer wall of the support frame 7 through a card seat 10. Multiple hot air terminals 9 are fixedly connected to both sides of the inner wall of the support frame 7. The multiple top connecting blocks 11 are grouped in pairs, and a cross frame 12 is fixedly connected between the multiple groups of top connecting blocks 11. Sliding sleeves 13 are slidably fitted on the outer walls of the two cross frames 12. Multiple sliding sleeves 13 are grouped in pairs, and a side telescopic sliding rod 14 is fixedly connected to one side of each group of sliding sleeves 13. One end of each side telescopic sliding rod 14 is fitted into a sleeve rod 15. The support frame 7, fixed to the top of the electric telescopic rod 6, adopts a frame structure design to reduce weight while ensuring sufficient strength. A perforated plate 8, made of corrosion-resistant metal sheet, is fixedly connected to the center of the top of the support frame 7. Multiple small perforations are formed on the surface to hold electron microscope samples and collect any overflowing embedding material. Multiple hot air terminals 9, made of high-temperature resistant metal, are fixedly connected to both sides of the inner wall of the support frame 7. These terminals connect to external hot air equipment to blow hot air, heating the embedding material and promoting its flow and solidification. Top connecting blocks 11 are fixedly connected to both sides of the outer wall of the support frame 7 via mounting brackets 10. The mounting brackets 10 are fixed using bolts or welding. The top connecting blocks 11, made of alloy material, are used to connect to the transverse support frame 12. The transverse support frame 12, made of metal rods, is fixedly connected between multiple sets of top connecting blocks 11, providing a sliding track for the sliding sleeve 13. The sliding sleeve 13, made of wear-resistant material, is slidably fitted onto the outer wall of the transverse support frame 12 and can slide freely along the transverse support frame 12. Multiple sliding sleeves 13 are arranged in pairs, and each pair of sliding sleeves 13 has a side telescopic sliding rod 14 fixedly connected to one side. The side telescopic sliding rod 14 is a telescopic metal rod, with one end sleeved inside the sleeve rod 15. The sleeve rod 15 is fixed to the support frame 7 or other fixed structure. The side telescopic sliding rod 14 can extend and retract within the sleeve rod 15. In conjunction with the sliding of the sliding sleeves 13, it can assist in fixing the sample on the stencil 8 from different directions, preventing the sample from shifting during the embedding process.

[0028] As one implementation method, such as Figure 2 and Figure 3As shown, an embedding mechanism is provided on one side of the outer wall of the transmission base 1. The embedding mechanism includes a support column 16 fixed to one side of the outer wall of the transmission base 1. A transmission structure 17 is provided at the top of the support column 16. A drive motor 18 is provided on one side of the top of the transmission structure 17. A threaded rod 19 is fixedly connected to one side of the bottom end of the transmission structure 17. A push terminal 20 is threadedly sleeved at the bottom end of the threaded rod 19. An embedding tube 21 is sleeved on the outer wall of the push terminal 20. One side of the outer wall of the embedding tube 21 is fixedly connected to one side of the support column 16 by a fixing bracket 22. A feeding box 23 is fixedly connected to the other side of the outer wall of 1. A support column 16 is fixedly connected to one side of the outer wall of the transmission seat 1, which is vertically fixed on the transmission seat 1 to provide support for the embedding mechanism. A transmission structure 17 is set at the top of the support column 16 to transmit the power of the drive motor 18 to the threaded rod 19. The drive motor 18 is set at the top side of the transmission structure 17 and is a servo motor to provide power for the conveying of the embedding material. The threaded rod 19 is fixedly connected to the bottom side of the transmission structure 17. It is made of the same material as the threaded rod 3 and has precision threads machined on its surface. When the drive motor 18 is working, it drives the threaded rod 19 to rotate through the transmission structure 17. The push terminal 20, which is threaded at the bottom of the threaded rod 19, is made of wear-resistant material. Its outer wall fits tightly with the inner wall of the embedding tube 21. The embedding tube 21 is made of transparent high-strength plastic, which makes it easy to observe the remaining amount and flow of the embedding material. One side of its outer wall is fixedly connected to one side of the support column 16 through the fixing bracket 22. The fixing bracket 22 ensures the stability of the embedding tube 21. The feeding box 23 is fixedly connected to the other side of the outer wall of the embedding tube 21 for storing the embedding material. The feeding box 23 is connected to the inside of the embedding tube 21 and can replenish the embedding material into the embedding tube 21 at any time. When the threaded rod 19 rotates, the push terminal 20 moves downward along the axial direction of the threaded rod 19, pushing the embedding material in the embedding tube 21 downward to complete the embedding operation of the sample on the stencil 8.

[0029] In this embodiment, the adjustable-angle electron microscope sample embedding device is placed on a horizontal worktable. An appropriate amount of embedding material is added to the feeding box 23, and the embedding material flows into the embedding material tube 21. The electron microscope sample is placed on the stencil 8 at the top of the support frame 7. According to the size and shape of the sample, the sample is fixed from different directions by sliding the sliding sleeve 13 and adjusting the extension and retraction of the side telescopic sliding rod 14 within the sleeve rod 15 to ensure that the sample does not move during the embedding process. According to the embedding requirements, the drive motor 2 is started, which drives the threaded rod 3 to rotate, causing the transmission seat 4 to move along the threaded rod 3 and adjust the position of the sample in the horizontal direction. The electric telescopic rod 6 is controlled to extend and retract, adjusting the height of the sample in the vertical direction. By adjusting the difference in the extension and retraction of the electric telescopic rod 6, the support frame 7 can be tilted to adjust the sample angle and meet the embedding requirements of different angles. When the angle and position of the sample are adjusted to the correct position, the drive motor 18 is started, which drives the threaded rod 19 to rotate through the transmission structure 17, pushing the terminal 20 downward and pushing the embedding material in the embedding material tube 21 onto the sample on the stencil 8. Simultaneously, the hot air terminal 9 can be activated to blow out hot air to heat the embedding material, promote the flow and solidification of the embedding material, and make the embedding material evenly cover the sample surface to complete the embedding operation. After the embedding is completed, all drive motors and hot air terminal 9 are turned off. After the embedding material solidifies, the positioning mechanism is released to fix the sample, and the embedded sample is removed for subsequent processing.

[0030] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
