Description

Technical Field

[0001] This utility model relates to the field of microscope technology, specifically to a stage that is compatible with microscopes and can be adjusted at multiple angles. Background Technology

[0002] A microscope stage, also known as a microscope worktable or sample stage, is a common laboratory piece of equipment primarily used for observing and manipulating samples under a microscope. It allows for changes in the relative position of the sample and the microscope, enabling researchers to conduct more precise and detailed observations. In modern scientific research and industrial production, the design and function of the microscope stage are crucial for improving the efficiency and accuracy of microscope use. With technological advancements, modern stages are typically equipped with sophisticated motion control systems, allowing users to precisely control the movement of the sample in three dimensions, which is essential for acquiring clear sample images and performing accurate measurements. These features not only improve work efficiency but also expand the application range of microscopes, making them indispensable tools in many fields such as biology, materials science, and semiconductor manufacturing.

[0003] Commercially available stages are typically designed to move in the XY plane and rotate on the Z axis. They rarely consider the angle adjustment when observing inclined samples, requiring operators to manually adjust and fix the tilt angle of the sample, which can lead to significant observation errors. For example, the patent application CN105068233A - Microscope Stage can only translate in the XY plane and rotate on the Z axis, which cannot meet the needs of observing metal microstructures from multiple angles.

Therefore, the fixed base plate 1 of this utility model should have a limiting hole 11 in the middle that matches the black and white working plate 101. Figure 3The limiting hole 11 is provided with an annular boss 12 that matches the annular groove 102. By inserting the annular boss 12 into the annular groove 102 of the microscope base, the corresponding black and white working plate 101 is inserted into the limiting hole 11, so that the stage of this utility model can be fixedly installed on the base of the microscope. Based on the installation structure adapted to the base of the Sunny Optical SZN71 continuous zoom stereomicroscope, the Y-direction translation structure 2, the X-direction translation base plate 4 and the "U"-shaped mounting base 6 of this utility model are all provided with through holes that are vertically connected to the limiting hole 11. The through holes are mainly for light transmission to facilitate the observation of the sample. When adapting to other models of microscopes, the installation structure can be adapted according to the structure of the microscope base. The Y-axis translation structure 2 is slidably assembled on the fixed base plate 1, with the sliding direction being the Y-axis direction. Specifically, as follows: Figure 4 and Figure 5 The Y-direction translation structure 2 includes a Y-direction translation base plate 21 slidably assembled to the top of the fixed base plate 1, a first sliding base plate 22 slidably assembled to the left side of the fixed base plate 1, and a second sliding base plate 23 slidably assembled to the right side of the fixed base plate 1. The Y-direction translation base plate 21 is fixedly connected to the first sliding base plate 22 and the second sliding base plate 23. A transmission groove 24 is provided between the first sliding base plate 22 and the Y-direction translation base plate 21. The sliding assembly form between the Y-direction translation base plate 21 and the top of the fixed base plate 1 is as follows: The Y-direction adjustment component 3 is disposed within the transmission groove 24. It is used to adjust the position of the Y-direction translation structure 2 in the Y-axis direction. Specifically, as shown in the figure... Figure 5 and Figure 6 , The Y-direction adjustment assembly 3 includes a Y-direction adjustment shaft 31, a Y-direction adjustment gear 32, and a Y-axis translation rack 33. The bottom end of the Y-direction adjustment shaft 31 is rotatably mounted on the first sliding base plate 22 via a bearing, and the top end extends vertically upward through the Y-direction translation base plate 21 and the X-direction translation base plate 4 in sequence. The Y-direction adjustment gear 32 is coaxially fixedly mounted on the bottom of the Y-direction adjustment shaft 31. The Y-axis translation rack 33 is fixedly mounted on the side of the fixed base plate 1 and the tooth surface extends horizontally into the transmission groove 24. The Y-direction adjustment gear 32 meshes with the Y-axis translation rack 33. A Y-direction translation adjustment knob 34 is coaxially fixedly provided at the top end of the Y-direction adjustment shaft 31. The top of the fixed base plate 1 is provided with two Y-direction sliding grooves 13, which are parallel to the Y-axis translation rack 33, respectively. Figure 5 and Figure 6 The bottom of the Y-direction translation base plate 21 is provided with Y-direction slide rails 211 that are respectively adapted to slide with the two Y-direction slide grooves 13. The two Y-direction slide rails 211 at the bottom of the Y-direction translation base plate 21 are slidably assembled in the two Y-direction slide grooves 13 at the top of the fixed base plate 1 to achieve the sliding assembly of the two in the Y-axis direction. By rotating the Y-direction translation adjustment knob 34, the Y-direction adjustment shaft 31 and the Y-direction adjustment gear 32 are driven to rotate. During the rotation of the Y-direction adjustment gear 32, its meshing position with the Y-axis translation rack 33 changes. Since the Y-axis translation rack 33 is fixed on the fixed base plate 1, its position remains unchanged. The rotation of the Y-direction adjustment gear 32 will cause the entire Y-direction translation structure 2, together with the Y-direction adjustment shaft 31 and the Y-direction adjustment gear 32, to translate in the Y-axis direction, thereby realizing the position adjustment of the Y-direction translation structure 2 in the Y-axis direction. The X-direction translation substrate 4 is slidably mounted on top of the Y-direction translation substrate 21, as follows: Figure 2 and Figure 7 The sliding direction is the X-axis direction. A notch 41 is provided on the X-axis translation base plate 4 directly above the Y-axis adjustment component 3. Figure 8 and Figure 9 ; The X-direction adjustment component 5 is disposed within the notch 41. It is used to adjust the position of the X-direction translation substrate 4 along the X-axis, as shown in the figure. Figure 8 , The X-direction adjustment assembly 5 includes an X-direction adjustment shaft 51, an X-direction adjustment gear 52, and an X-axis translation rack 53. The X-direction adjustment shaft 51 is rotatably mounted on the Y-direction adjustment shaft 31, and the X-direction adjustment gear 52 is coaxially and fixedly mounted on the bottom of the X-direction adjustment shaft 51. Figure 10 and Figure 11 The notch 41 of the fixed assembly of the X-axis translation rack 53, on the side of the X direction, the X-direction adjusting gear 52 meshes with the X-axis translation rack 53, and the top of the X-direction adjusting shaft 51 is coaxially fixed with an X-direction translation adjusting knob 54. The sliding assembly method of X-direction translation substrate 4 and Y-direction translation substrate 21: The top of the Y-direction translation substrate 21 is provided with two X-direction grooves 212, which are parallel to the X-axis translation rack 53, respectively. Figure 8 and Figure 9 The bottom of the X-direction translation substrate 4 is provided with X-direction slide rails 43 that are respectively adapted to slide with the two X-direction slide grooves 212. The two slide rails 43 are slidably fitted into the two X-direction slide grooves 212 at the bottom of the X-direction translation substrate 4 and the two X-direction slide grooves 212 at the top of the Y-direction translation substrate 21 to achieve the sliding assembly of the two in the X-axis direction. The top of the fixed base plate 1 is provided with two Y-direction sliding grooves 13, each parallel to the Y-axis translation rack 33. The bottom of the Y-direction translation base plate 21 is provided with Y-direction slide rails 211, each slidingly adapted to the two Y-direction sliding grooves 13. Figure 4 ; By rotating the X-direction translation adjustment knob 54, the X-direction adjustment shaft 51 and the X-direction adjustment gear 52 are driven to rotate. During the rotation of the X-direction adjustment gear 52, its meshing position with the X-axis translation rack 53 changes. Since the X-axis translation rack 53 is fixed on the X-direction translation base plate 4, its position in the X-direction remains unchanged. The rotation of the X-direction adjustment gear 52 will cause the X-direction translation base plate 4 to translate in the X-axis direction, thereby realizing the position adjustment of the X-direction translation base plate 4 in the X-axis direction. The U-shaped mounting bracket 6 is fixedly assembled on the top of the X-direction translation base plate 4. The actual fixed installation position should not affect the position adjustment in the X and Y axis directions; it should be offset to one side. Figure 2 It does not interfere with the Y-direction adjustment axis 31, the Y-direction translation adjustment knob 34, the X-direction adjustment axis 51, and the X-direction translation adjustment knob 54. The stage 7 is set inside the opening of the U-shaped mounting base 6, and its two ends are respectively rotatably assembled with the two vertical plates of the U-shaped mounting base 6. Specifically, as shown... Figure 12 , Figure 13 and Figure 14 The bottom center of the left and right sides of the stage 7 is fixed with an outwardly protruding X-axis rotating column 73. Each X-axis rotating column 73 is rotatably assembled with the two vertical plates of the "U"-shaped mounting base 6 through bearings.

The X-axis rotation angle adjustment gear 82 is coaxially and fixedly assembled on the X-axis rotation angle adjustment shaft 81 and located between the angle plate 72 and the vertical plate of the U-shaped mounting seat 6. The X-axis rotation arc rack 83 is fixedly assembled on the outer side of the angle plate 72. The X-axis rotation angle adjustment gear 82 meshes with the X-axis rotation arc rack 83. The X-axis rotation arc rack 83 and the X-axis rotation post 73 are arranged coaxially, with the X-axis as the rotation axis. One end of the X-axis rotation angle adjustment shaft 81 extending to the outside of the U-shaped mounting seat 6 is provided with an X-axis rotation angle adjustment knob 84. By turning the X-axis rotation angle adjustment knob 84, the X-axis rotation angle adjustment shaft 81 and the X-axis rotation angle adjustment gear 82 are driven to rotate. During the rotation of the X-axis rotation angle adjustment gear 82, the meshing position between it and the X-axis rotation arc rack 83 changes. The X-axis rotation arc rack 83 is fixed on the stage 7, and the stage 7 is rotatably assembled on the two vertical plates of the U-shaped mounting seat 6. The X-axis rotation arc rack 83 and the X-axis rotation post 73 are arranged coaxially, so the rotation of the X-axis rotation angle adjustment gear 82 will cause the X-axis rotation arc rack 83 to rotate around the X-axis as the rotation axis, realizing the adjustment of the inclination angle of the stage 7 in the X-axis direction. The adjustment range of the inclination angle of the stage 7 of the present utility model in the X-axis direction is ±30°; In actual arrangement, the two vertical plates of the U-shaped mounting seat 6 are arranged with one higher and one lower, such as Figure 13 and Figure 14 , one end of the stage 7 is rotatably assembled at the top end of the lower vertical plate, and the other end is rotatably assembled at the middle part of the higher vertical plate. The angle plate 72 is disposed at the end close to the higher vertical plate, and the X-axis rotation angle adjustment assembly 8 is disposed between the higher vertical plate and the angle plate 72. In addition, a shaft seat arranged opposite to the higher vertical plate for fixing the end of the X-axis rotation angle adjustment shaft 81 is further fixedly disposed on the inner side of the higher vertical plate. One end of the X-axis rotation angle adjustment shaft 81 is rotatably assembled on the shaft seat through a bearing, and the other end is rotatably assembled at the top end of the higher vertical plate of the U-shaped mounting seat 6 through a bearing and extends outward for assembling the X-axis rotation angle adjustment knob 84; In order to realize stable adjustment of the inclination angle of the stage 7 in the X-axis direction, an arc-shaped sliding groove 831 is further opened on the X-axis rotation arc rack 83, such as Figure 14 , the arc-shaped sliding groove 831 is coaxial with the X-axis rotation post 73 and the X-axis rotation arc rack 83, with the X-axis as the rotation axis. A limit guide post 61 is disposed on the vertical plate of the U-shaped mounting seat 6. One end of the limit guide post 61 is fixedly assembled on the vertical plate of the U-shaped mounting seat 6, and the other end is slidably assembled in the arc-shaped sliding groove 831. Through the sliding limit fit between the limit guide post 61 and the arc-shaped sliding groove 831, the stage 7 can be prevented from shifting during rotation; Z-axis rotation angle adjustment component 9 is disposed between the stage 7 and the sample placement stage 71, and is used to adjust the rotation angle of the sample placement stage 71 in the Z-axis direction. Specifically, as shown in... Figure 15 , Figure 16 and Figure 17 , The Z-axis rotation angle adjustment assembly 9 includes a Z-axis rotation angle adjustment shaft 91, a Z-axis rotation angle adjustment gear 92, and a Z-axis rotation ring rack 93. The bottom end of the Z-axis rotation angle adjustment shaft 91 is fixedly mounted on the stage 7 via a bearing, and the top end extends vertically upward. The Z-axis rotation angle adjustment gear 92 is coaxially fixedly fitted onto the bottom of the Z-axis rotation angle adjustment shaft 91. The Z-axis rotation ring rack 93 is coaxially fixedly mounted onto the bottom of the sample placement stage 71. The Z-axis rotation angle adjustment gear 92 meshes with the Z-axis rotation ring rack 93. The top end of the Z-axis rotation angle adjustment shaft 91... The end is equipped with a Z-axis rotation angle adjustment knob 94. By rotating the Z-axis rotation angle adjustment knob 94, the Z-axis rotation angle adjustment shaft 91 and the Z-axis rotation angle adjustment gear 92 are driven to rotate. During the rotation of the Z-axis rotation angle adjustment gear 92, its meshing position with the Z-axis rotation ring rack 93 changes, causing the Z-axis rotation ring rack 93 to rotate around the Z-axis, thereby realizing the adjustment of the rotation angle of the sample placement stage 71 in the Z-axis direction. The adjustment range of the rotation angle of the sample placement stage 71 in the Z-axis direction of this utility model is 360°.

[0024] This utility model also provides dustproof covers on the side of the X-direction translation base plate 4 that is offset from the "U"-shaped mounting seat 6 and on the stage 7.

[0025] Working principle: The stage of this invention is fixedly installed on the microscope base, and the glass slide containing the sample is placed on the sample placement stage 71. Adjust the sample stage 71 to be directly below the microscope according to the observation requirements: X-axis position adjustment: Rotate the X-axis translation adjustment knob 54 to drive the X-axis adjustment shaft 51 and the X-axis adjustment gear 52 to rotate. The rotation of the X-axis adjustment gear 52 drives the X-axis translation rack 53 to translate in the X-axis direction. Since the X-axis translation rack 53 is fixed on the X-axis translation base plate 4, and the U-shaped mounting base 6 is fixed on the X-axis translation base plate 4, the stage 7 is assembled on the U-shaped mounting base 6, thereby realizing the position adjustment of the stage 7 and the sample placement stage 71 in the X-axis direction. Y-axis position adjustment: Rotate the Y-axis translation adjustment knob 34 to drive the Y-axis adjustment shaft 31 and the Y-axis adjustment gear 32 to rotate. The rotation of the Y-axis adjustment gear 32 causes the entire Y-axis translation structure 2, together with the Y-axis adjustment shaft 31 and the Y-axis adjustment gear 32, to translate in the Y-axis direction. Since the X-axis translation base plate 4 is slidably mounted on the Y-axis translation structure 2 along the X-axis direction, the relative position of the X-axis translation base plate 4 and the Y-axis translation structure 2 remains unchanged in the X-axis direction. The change in the position of the Y-axis translation structure 2 in the Y-axis direction will cause the X-axis translation base plate 4, together with the "U"-shaped mounting base 6, the stage 7 and the sample placement stage 71, to change in the X-axis direction, thereby realizing the position adjustment of the stage 7 and the sample placement stage 71 in the Y-axis direction. Z-axis rotation angle adjustment: Rotate the Z-axis rotation angle adjustment knob 94 to drive the Z-axis rotation angle adjustment shaft 91 and the Z-axis rotation angle adjustment gear 92 to rotate. The rotation of the Z-axis rotation angle adjustment gear 92 drives the Z-axis rotation ring rack 93 to rotate, thereby driving the sample placement stage 71 to rotate, thus realizing the rotation angle adjustment of the sample placement stage 71 in the Z-axis direction. X-axis tilt angle adjustment: Rotate the X-axis rotation angle adjustment knob 84 to drive the X-axis rotation angle adjustment shaft 81 and the X-axis rotation angle adjustment gear 82 to rotate. The rotation of the X-axis rotation angle adjustment gear 82 drives the X-axis rotating arc rack 83 to rotate around the X-axis, thereby realizing the adjustment of the tilt angle of the stage 7 in the X-axis direction.

[0026] The above operations enable multi-dimensional and multi-angle position adjustment of the sample placement stage 71, facilitating comprehensive and detailed observation of the sample on the sample placement stage 71.

[0027] It should be understood that by adjusting the tilt angle in the X-axis direction and the rotation angle in the Z-axis direction, it is possible to observe the sample from all angles.

[0028] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
