Description

Technical Field

[0001] This utility model belongs to the technical field of microscope auxiliary equipment, specifically relating to a high-precision electric displacement platform. Background Technology

[0002] In precision measurement fields such as biomedicine, materials science, and microelectronics testing, electric displacement platforms are core components for achieving accurate sample positioning. Their positioning accuracy, operational stability, and system compatibility directly affect the reliability of test results. Existing microscope stages mostly use manual knob adjustment, which is inefficient and makes it difficult to achieve high-precision repeatability. Furthermore, in high-frequency reciprocating motion, uneven force on the rolling elements can cause micro-vibrations, resulting in repeatability deviations exceeding ±1μm. This makes it difficult to meet the requirements of high-precision microscopic observation and affects the accuracy of data acquisition. Utility Model Content

[0003] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a high-precision electric displacement platform.

[0004] To achieve the above technical objectives, the technical solution adopted by this utility model is as follows:

[0005] A high-precision electric displacement platform includes a slide holder, the bottom of which is fixedly mounted on a microscope holder. A displacement platform motor mounting plate is mounted on the top of the slide holder. An X-axis moving component and a Y-axis moving component are mounted on the displacement platform motor mounting plate. The power output end of the X-axis moving component is connected to a displacement platform cover plate, which is slidably mounted on the displacement platform motor mounting plate. A long cover plate is mounted on the outside of the X-axis moving component, and a short cover plate is mounted on the outside of the Y-axis moving component. A Y-axis crossed roller guide is installed between the slide holder and the displacement platform motor mounting plate, and an X-axis crossed roller guide is installed between the displacement platform motor mounting plate and the displacement platform cover plate.

[0006] Further specifying, the X-axis moving assembly includes an X-axis motor base, an X-axis lead screw motor mounted on one side of the X-axis motor base, an X-axis lead screw connected to the power output end of the X-axis lead screw motor, an X-axis bearing housing connected to the other side of the X-axis lead screw, and a long slider seat connected to the X-axis lead screw. The displacement platform motor fixing plate has a clearance guide groove at the corresponding long slider seat, and the long slider seat is slidably disposed within the clearance guide groove. The other side of the long slider seat is mounted on the displacement platform cover plate. X-axis sensors are mounted on one side of both the X-axis motor base and the X-axis bearing housing, and the X-axis sensors are connected to the X-axis lead screw motor. This structural design facilitates the X-axis reciprocating motion of the displacement platform cover plate.

[0007] Further specifying, the Y-axis movement assembly includes a Y-axis motor mount fixedly installed on the displacement platform motor mounting plate. A Y-axis lead screw motor is mounted on one side of the Y-axis motor mount, and the power output end of the Y-axis lead screw motor is connected to a Y-axis lead screw. A Y-axis bearing seat is mounted on the other side of the Y-axis lead screw, and the Y-axis bearing seat is fixedly installed on the displacement platform motor mounting plate. A slider seat is connected to the Y-axis lead screw, and one side of the slider seat is locked onto a glass slide mounting base. A triangular nut is installed on the Y-axis lead screw, and the slider seat is connected to the triangular nut. A Y-axis sensor is mounted on one side of both the Y-axis motor mount and the Y-axis bearing seat, and the Y-axis sensor is connected to the Y-axis lead screw motor. This structural design facilitates the Y-axis reciprocating motion of the displacement platform motor mounting plate.

[0008] Furthermore, the slide holder has several adjustment holes on the side corresponding to the Y-axis crossed roller guide, and the displacement platform motor mounting plate has a side V-shaped guide limit block installed at the location corresponding to the X-axis crossed roller guide. This structural design facilitates the adjustment of the preload of the Y-axis and X-axis crossed roller guides.

[0009] Furthermore, an interface board is installed on one side of the bottom of the motor mounting plate of the displacement platform. This structural design allows for compatibility with the native control interface via the interface board, controlling the X and Y axis movements of the electric displacement platform, ensuring signal compatibility with the microscope host, and providing system protection.

[0010] The beneficial effects of this utility model are as follows: This utility model achieves automated displacement adjustment of the displacement platform motor fixing plate and displacement platform cover plate by driving the X-axis moving component and the Y-axis moving component, eliminating the cumbersome operation of traditional manual knob adjustment, and greatly improving the efficiency of displacement adjustment. It is especially suitable for microscopic observation scenarios that require frequent position adjustments. Furthermore, the installation of Y-axis and X-axis cross roller guides, which have the characteristics of low friction coefficient, smooth movement, and high guiding accuracy, can effectively reduce the error when moving in the X-axis and Y-axis directions. At the same time, the setting of X-axis and Y-axis sensors can accurately control the forward and reverse rotation of the motor, realizing the precise reciprocating motion of the displacement platform. This solves the problem that the traditional stage has a repeatability deviation of more than ±1μm due to the micro-vibration caused by uneven force on the rolling elements in high-frequency reciprocating motion. It significantly improves the repeatability accuracy, meets the stringent requirements of high-precision microscopic observation for displacement accuracy, and provides a strong guarantee for the accuracy of data acquisition.

[0017] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] Example 1, as Figure 1 , Figure 2 and Figure 3 As shown, a high-precision electric displacement platform is provided. The bottom of a slide holder 1 is fixedly mounted on a microscope holder. A displacement platform motor mounting plate 2 is mounted on the top of the slide holder 1. An X-axis moving component 3 and a Y-axis moving component 4 are mounted on the displacement platform motor mounting plate 2. The power output end of the X-axis moving component 3 is connected to a displacement platform cover plate 5. The displacement platform cover plate 5 is slidably mounted on the displacement platform motor mounting plate 2. A long cover plate 6 is mounted on the outside of the X-axis moving component 3, and a short cover plate 7 is mounted on the outside of the Y-axis moving component 4. A Y-axis crossed roller guide 25 is installed between the slide holder 1 and the displacement platform motor mounting plate 2, and an X-axis crossed roller guide 26 is installed between the displacement platform motor mounting plate 2 and the displacement platform cover plate 5.

[0019] In this embodiment, the slide holder 1 adopts a dovetail groove structure and is embedded in the microscope holder, thus providing a stable foundation support for the entire device. The displacement platform motor fixing plate 2 is equipped with an X-axis moving component 3 and a Y-axis moving component 4. The power output end of the X-axis moving component 3 is connected to the displacement platform cover plate 5. The displacement platform cover plate 5 is slidably mounted on the displacement platform motor fixing plate 2 via an X-axis cross roller guide 26, ensuring the stability of the displacement platform cover plate 5 when moving in the X-axis direction. A Y-axis cross roller guide 25 is installed between the slide holder 1 and the displacement platform motor fixing plate 2, enabling the displacement platform motor fixing plate 2 to move stably in the Y-axis direction. The cross roller guide has the characteristics of low friction coefficient, smooth movement, and high guiding accuracy, which can effectively reduce the error when moving in the X-axis and Y-axis directions, ensuring the high precision of the displacement platform during movement and meeting the needs of scenarios with high displacement accuracy requirements, such as microscope observation.

[0020] In order to effectively protect the X-axis moving component 3, the displacement platform motor fixing plate 2 is equipped with a long cover plate 6 on the outside of the X-axis moving component 3. The long cover plate 6 covers the X-axis moving component 3 to prevent dust, debris and other objects from affecting its internal structure. Similarly, the displacement platform motor fixing plate 2 is equipped with a short cover plate 7 on the outside of the Y-axis moving component 4 to protect the Y-axis moving component 4.

[0021] Example 2, as Figure 2 As shown, this embodiment adds the following structure based on embodiment 1: the X-axis moving assembly 3 includes an X-axis motor base 8, an X-axis lead screw motor 9 is mounted on one side of the X-axis motor base 8, an X-axis lead screw 10 is connected to the power output end of the X-axis lead screw motor 9, an X-axis bearing seat 11 is connected to the other side of the X-axis lead screw 10, a long slider seat 12 is connected to the X-axis lead screw 10, the displacement platform motor fixing plate 2 is provided with a clearance guide groove 13 at the corresponding long slider seat 12, the long slider seat 12 is slidably disposed in the clearance guide groove 13, the other side of the long slider seat 12 is mounted on the displacement platform cover plate 5, an X-axis sensor 14 is mounted on one side of both the X-axis motor base 8 and the X-axis bearing seat 11, and the X-axis sensor 14 is connected to the X-axis lead screw motor 9.

[0022] In this embodiment, when axial movement along the X-axis is required, the X-axis lead screw motor 9 is started. The X-axis lead screw motor 9 drives the X-axis lead screw 10 to rotate along the X-axis bearing seat 11. The rotating X-axis lead screw 10 drives the long slider seat 12 to slide in the clearance guide groove 13, and at the same time drives the displacement platform cover plate 5 to move. When the displacement platform cover plate 5 moves, it slides stably on the displacement platform motor fixing plate 2 through the X-axis cross roller guide rail 26. When one side of the long slider seat 12 contacts the X-axis sensor 14 on the X-axis motor seat 8, the X-axis sensor 14 sends a signal to the X-axis lead screw motor 9, causing the X-axis lead screw motor 9 to reverse. When the other side of the long slider seat 12 contacts the X-axis sensor 14 on the X-axis bearing seat 11, the X-axis sensor 14 sends a signal to the X-axis lead screw motor 9 again, causing the X-axis lead screw motor 9 to rotate forward, thereby driving the displacement platform cover plate 5 to achieve the effect of reciprocating motion.

[0023] Example 3, as Figure 2 As shown, this embodiment adds the following structure based on embodiment 1: The Y-axis moving assembly 4 includes a Y-axis motor seat 15 fixedly mounted on the displacement platform motor fixing plate 2. A Y-axis lead screw motor 16 is mounted on one side of the Y-axis motor seat 15. The power output end of the Y-axis lead screw motor 16 is connected to a Y-axis lead screw 17. A Y-axis bearing seat 18 is mounted on the other side of the Y-axis lead screw 17. The Y-axis bearing seat 18 is fixedly mounted on the displacement platform motor fixing plate 2. The Y-axis lead screw 17 is connected to a slider seat 19. One side of the slider seat 19 is locked onto the glass slide fixing seat 1. A triangular nut 20 is mounted on the Y-axis lead screw 17. The slider seat 19 is connected to the triangular nut 20. A Y-axis sensor 21 is mounted on one side of both the Y-axis motor seat 15 and the Y-axis bearing seat 18. The Y-axis sensor 21 is connected to the Y-axis lead screw motor 16.

[0024] In this embodiment, the slide holder 1 is connected to the slider seat 19, and the slider seat 19 is connected to the triangular nut 20. The Y-axis lead screw motor 16 and the Y-axis lead screw 17 are fixed on the Y-axis motor seat 15 and the Y-axis bearing seat 18. The Y-axis motor seat 15 and the Y-axis bearing seat 18 are fixed on the displacement platform motor fixing plate 2. After the Y-axis lead screw motor 16 is started, the Y-axis lead screw motor 16 drives the Y-axis lead screw 17 to rotate. Since the slider seat 19 is fixedly connected to the slide holder 1, and the slide holder 1 is embedded in the microscope holder with a dovetail groove structure, the Y-axis lead screw 17 drives the Y-axis lead screw motor 16 to produce... The Y-axis motor mount 15 and Y-axis bearing mount 18 generate moving force, thereby driving the displacement platform motor fixing plate 2 to move along the Y-axis. During the movement, when the Y-axis sensor 21 on the Y-axis motor mount 15 contacts the slider seat 19, the Y-axis sensor 21 sends a signal to the Y-axis lead screw motor 16, causing the Y-axis lead screw motor 16 to reverse. When the Y-axis sensor 21 on the Y-axis bearing mount 18 contacts the slider seat 19, the Y-axis sensor 21 sends a signal to the Y-axis lead screw motor 16 again, causing the Y-axis lead screw motor 16 to rotate forward, thereby driving the displacement platform motor fixing plate 2 to achieve the effect of reciprocating motion.

[0025] Example 4, as Figure 2 and Figure 3 As shown, this embodiment adds the following structure to the embodiment 1: the slide fixing seat 1 is provided with several adjustment holes 22 on the side of the Y-axis cross roller guide 25, and the displacement platform motor fixing plate 2 is equipped with a side V-shaped guide rail limit block 23 at the position corresponding to the X-axis cross roller guide 26.

[0026] In this embodiment, during use, the Y-axis cross roller guide 25 can be adjusted through the adjustment hole 22 on the side of the glass slide fixing seat 1, and the X-axis cross roller guide 26 can be adjusted through the side V-shaped guide limit block 23, thereby adjusting the preload of the cross roller guide and improving stability.

[0027] Example 5, as Figure 2 As shown, this embodiment adds the following structure to the embodiment 1: an interface plate 24 is installed on one side of the bottom of the displacement platform motor fixing plate 2.

[0028] In this embodiment, the interface board 24 is compatible with the native control interface to control the X and Y axis movement of the electric displacement platform, ensuring signal compatibility and system protection with the microscope host.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
