[0001] This invention belongs to the technical field of biological experimental equipment, specifically a leveling device, a scanning imaging platform, and a leveling method. Background Technology

[0002] In experiments typically conducted in industries such as precision instruments, especially in line scan camera platforms, the imaging device is positioned above the mounting stage. The mounting stage is used to hold the sample, and the imaging device is used to scan and image the sample.

[0003] To ensure sharp pixels in the final image, the mounting stage and imaging device must be perpendicular to each other or the mounting stage must be horizontal. However, assembly errors often prevent the mounting stage from being horizontal. Therefore, a scanning imaging platform with an adjustable mounting stage is needed. Summary of the Invention

[0004] The purpose of this invention is to improve the problem that existing scanning imaging platforms cannot adjust the clamping stage to be horizontal, and to provide a leveling device, a scanning imaging platform, and a leveling method.

[0005] The technical solutions for achieving the above objectives include the following:

[0006] The leveling device includes: a first support plate, a second support plate, an elastic element, and at least three driving components. The second support plate has a first end, a second end, and a third end. The three driving components are respectively disposed at the first end, the second end, and the third end, and the first end, the second end, and the third end are not on the same straight line.

[0007] The first support plate is movably disposed on the second support plate, and a bearing surface is formed on the first support plate. The two ends of the elastic member are respectively installed on the first support plate and the second support plate.

[0008] Each of the aforementioned drive components includes a drive element, a drive shaft, a sensor, and a sensing element. The drive element is mounted on a second support plate, and the first end of the drive shaft is mounted on the output end of the drive element. The first support plate has at least three first abutting members, and the second ends of the three drive shafts respectively contact the three first abutting members.

[0009] The sensing element is mounted on the drive shaft, the sensor is mounted on the second support plate, the sensing element is positioned close to the sensor, and the sensor is electrically connected to the drive element.

[0010] In one embodiment, the three first abutting members each have a first contact surface, a second contact surface, and a second contact surface;

[0011] The first contact surface is horizontally positioned;

[0012] The second contact surface is concave inward and forms an inner arc surface;

[0013] One of the first abutting parts has a V-shaped cross-section so that the third contact surface forms a bevel;

[0014] The first contact surface, the second contact surface, and the third contact surface are respectively used to abut against the three drive shafts.

[0015] In one embodiment, the drive assembly has a first adjusting member mounted on the second end of the drive shaft. The first adjusting member is spherical and has an outer arc surface that abuts against a first contact surface, a second contact surface, or a third contact surface.

[0016] In one embodiment, the leveling device further includes three connectors, which are respectively disposed near the first end, the second end, and the third end of the second support plate;

[0017] Each of the aforementioned connectors includes a second abutting member and a second adjusting member. The second abutting member is installed under the first support plate, and the second adjusting member is installed on the second support plate. The second adjusting member cooperates with the second abutting member.

[0018] The shapes of the three second abutment members correspond one-to-one with the shapes of the three first abutment members, and the corresponding first abutment members and second abutment members are arranged adjacent to each other.

[0019] In one embodiment, the number of elastic elements is three, and the three elastic elements are respectively disposed near the first end, the second end, and the third end of the second support plate.

[0020] In one embodiment, the first, second, and third ends of the second support plate together form an isosceles or equilateral triangle.

[0021] The present invention also proposes a scanning imaging platform, including a support, a clamping platform, an imaging device, and a leveling device as described above, wherein the leveling device is mounted on the support and the clamping platform is mounted on the bearing surface of the leveling device.

[0022] The imaging device is mounted on a bracket and positioned above the clamping platform.

[0023] In one embodiment, the imaging device includes an optical component, a line scan camera, and an objective lens. The optical component is mounted on the side wall of a bracket, the line scan camera is mounted at a first end of the optical component, and the objective lens is mounted at a second end of the optical component. The line scan camera and the objective lens are arranged opposite to each other.

[0024] In one embodiment, the imaging device further includes a laser ranging module, a first lifting mechanism, and a second lifting mechanism. The laser ranging module is installed at the second end of the optical component and is arranged parallel to the objective lens. The laser ranging module is electrically connected to the sensor.

[0025] The optical component is installed at the output end of the first lifting mechanism, which is installed at the upper end of the bracket; the leveling device is installed at the output end of the second lifting mechanism, which is installed at the lower end of the bracket.

[0026] The present invention also proposes a leveling method, comprising the following steps:

[0027] Step 1: Start the three drive components. The three drive components drive the three drive shafts to move up and down respectively, and the three drive shafts push the three first abutment components to move up and down respectively.

[0028] The first support plate moves up and down to pull the elastic element so that the elastic element is in a tensioned state.

[0029] Step 2: The three sensors respectively sense the vertical position values ​​of the three sensing elements. When the values ​​sensed by the three sensors are consistent, the three sensors simultaneously generate electrical signals, which drive the driving element to stop operating.

[0030] The technical solution provided by this invention has the following advantages and effects:

[0031] When the level of the bearing surface needs to be adjusted, the three drive components drive simultaneously. The three drive components drive the corresponding three drive shafts, causing the three drive shafts to push the three first abutment components up and down simultaneously, thereby adjusting the three adjustment points on the first support plate. Since the sensing element is installed on the drive shaft and the sensor is installed on the second support plate, the second support plate is in a stationary state. The sensor can sense the vertical position of the drive shaft through the sensing element. When the three drive shafts are at the same vertical height, the three sensors sense the same value from the sensing element, thereby determining that the first support plate is in a horizontal state and sending an electrical signal to the drive component to stop the drive component from working, thus realizing the leveling operation.

[0055] Example 1

[0056] This invention provides a leveling device 100, such as... Figures 1 to 3 As shown, it includes: a first support plate 10, a second support plate 20, an elastic element 40, and at least three drive assemblies 50. The second support plate 20 has a first end, a second end, and a third end. The three drive assemblies 50 are respectively disposed at the first end, the second end, and the third end, which are not on the same straight line. The first support plate 10 is movably disposed on the second support plate 20. A bearing surface 101 is formed on the upper part of the first support plate 10. The two ends of the elastic element 40 are respectively installed on the first support plate 10 and the second support plate 20. Each drive assembly... Each component 50 includes a drive component 51, a drive shaft 52, a sensor 21, and a sensing component 54. The drive component 51 is mounted on the second support plate 20. The first end of the drive shaft 52 is mounted on the output end of the drive component 51. The first support plate 10 has at least three first abutment members 11. The second ends of the three drive shafts 52 are respectively in contact with the three first abutment members 11. The sensing component 54 is mounted on the drive shaft 52. The sensor 21 is mounted on the second support plate 20. The sensing component 54 is positioned close to the sensor 21. The sensor 21 is electrically connected to the drive component 51.

[0057] Specifically, by setting the three drive components 50 at the first, second, and third ends of the second support plate 20 respectively, with the first, second, and third ends not on the same straight line, the adjustment points of the three drive components 50 can form a plane. Moreover, the first support plate 10 is movably set on the second support plate 20, and an elastic element 40 is provided between the first support plate 10 and the second support plate 20. The elastic element 40 keeps the first support plate 10 and the second support plate 20 in a tensioned state. The elastic element 40 is used to limit the range of motion of the first support plate 10 on the second support plate 20, preventing the first support plate 10 from coming off the second support plate 20, and also allowing the first support plate 10 to have a certain amount of room to move on the second support plate 20. When the first support plate 10 is adjusted to be horizontal, the reaction force of the elastic element 40 restricts the movement of the first support plate 10, thereby improving the support stability of the first support plate 10.

[0058] When the level of the bearing surface 101 needs to be adjusted, the three drive components 50 are driven simultaneously, and the three drive members 51 drive the corresponding three drive shafts 52 respectively, so that the three drive shafts 52 simultaneously push the three first abutment members 11 to move up and down, thereby adjusting the three adjustment points on the first support plate 10. Since the sensing element 54 is installed on the drive shaft 52 and the sensor 21 is installed on the second support plate 20, the second support plate 20 is in a stationary state. The sensor 21 can sense the vertical position of the drive shaft 52 through the sensing element 54. When the three drive shafts 52 are at the same height in the vertical direction, the three sensors 21 sense the same value of the sensing element 54, thereby determining that the first support plate 10 is in a horizontal state, and sending an electrical signal to the drive member 51 to stop the operation, realizing the horizontal leveling operation. The clamping table 206 is installed on the bearing surface 101. The bearing surface 101 is horizontal, and the clamping table 206 is also horizontal accordingly.

[0059] In this embodiment, the drive assembly 50 can be a screw jack, which consists of a worm gear reducer and a screw (drive shaft 52). Its reduction component is a worm gear drive, which uses the worm to drive the worm wheel to achieve speed reduction. Screw jacks can be purchased from the market.

[0060] In some embodiments, such as Figure 1 , Figure 4 , Figure 5 , Figure 6As shown, the three first abutting members 11 have a first contact surface 111, a second contact surface 112, and a third contact surface 113, respectively. The first contact surface 111 is horizontally arranged. The second contact surface 112 is concave inward and forms an inner arc surface. The cross-section of one of the first abutting members 11 is V-shaped so that the third contact surface 113 forms an inclined surface. The first contact surface 111, the second contact surface 112, and the third contact surface 113 are respectively used to abut against the three drive shafts 52. Specifically, the first contact surface 111, the second contact surface 112, and the third contact surface 113 are respectively used to abut against the three drive shafts 52, so that the three drive shafts 52 and the three first abutting members 11 form a first adjustment point, a second adjustment point, and a third adjustment point. The first contact surface 111 at the first adjustment point is horizontally arranged, and the drive shaft 52 moves up and down, causing the first adjustment point to move up and down. The second contact surface 112 at the second adjustment point has an inner arc surface. When the drive shaft 52 moves up and down, the first support plate 10 is restricted by the elastic member 40, causing the second adjustment point to move up and down. The inner arc surface of the second contact surface 112 rotates around the drive shaft 52, improving the flexibility of the first support plate 10. The third contact surface 113 at the third adjustment point has an inclined surface. When the drive shaft 52 moves up and down, causing the third adjustment point to move up and down, the third contact surface 113 slides through the inclined surface, thereby driving the first support plate 10 to swing laterally, further improving the flexibility of the first support plate 10. Therefore, by setting the three first abutting members 11 to different shapes, the three different first contact surfaces 111, second contact surfaces 112, and third contact surfaces 113 abut against the three drive shafts 52 respectively, and then using the tension of the elastic member 40, the flexibility of the first support plate 10 on the second support plate 20 is improved, making it easier for the first support plate 10 to be adjusted to a horizontal position.

[0061] Specifically, such as Figure 1 As shown, when the three drive shafts 52 move up and down, since the three different first contact surfaces 111, second contact surfaces 112, and third contact surfaces 113 respectively abut against the three drive shafts 52, the first adjustment point, the second adjustment point, and the third adjustment point have different degrees of freedom in the vertical movement distance and direction; this can further improve the flexibility of the first support plate 10 on the second support plate 20.

[0062] In some embodiments, such as Figure 1 and Figure 2As shown, the drive assembly 50 has a first adjusting member 53, which is mounted on the second end of the drive shaft 52. The first adjusting member 53 is spherical and has an outer arc surface. The outer arc surface of the first adjusting member 53 abuts against the first contact surface 111, the second contact surface 112, or the third contact surface 113. Specifically, by mounting the first adjusting member 53 on the drive shaft 52 and abutting against the first contact surface 111, the second contact surface 112, or the third contact surface 113, the friction between the drive shaft 52 and the first abutting member 11 can be reduced, making it easier for the first contact surface 111, the second contact surface 112, and the third contact surface 113 to slide on the drive shaft 52, further improving the flexibility of the first support plate 10 on the second support plate 20.

[0063] In some embodiments, if 1 to Figure 3 As shown, the leveling device 100 also has three connecting members 30, which are respectively located near the first end, second end, and third end of the second support plate 20. Each connecting member 30 includes a second abutment 31 and a second adjusting member 32. The second abutment 31 is installed under the first support plate 10, and the second adjusting member 32 is installed on the second support plate 20. The second adjusting member 32 cooperates with the second abutment 31. The shapes of the three second abutment members 31 correspond one-to-one with the shapes of the three first abutment members 11, and the corresponding first abutment members 11 and second abutment members 31 are arranged adjacent to each other. Specifically, by setting three connecting members 30 between the first support plate 10 and the second support plate 20, and by having the second abutment members 31 of the connecting members 30 cooperate with the second adjusting members 32, a fourth adjustment point, a fifth adjustment point, and a sixth adjustment point can be formed between the first support plate 10 and the second support plate 20. Since the shapes of the three second abutment members 31 correspond one-to-one with the shapes of the three first abutment members 11, and the corresponding first abutment members 11 and second abutment members 31 are arranged adjacent to each other, the movement modes of the fourth adjustment point, fifth adjustment point, and sixth adjustment point correspond to the first adjustment point, second adjustment point, and third adjustment point, respectively, so that there are six free adjustment points between the first support plate 10 and the second support plate 20, which further improves the flexibility of the first support plate 10 on the second support plate 20. In this embodiment, both the first adjustment member 53 and the second adjustment member 32 are spherical nuts.

[0064] Preferred, such as Figure 1As shown, there are three elastic elements 40, which are respectively positioned near the first, second, and third ends of the second support plate 20. Specifically, since the two ends of the elastic elements 40 are fixed to the first support plate 10 and the second support plate 20 respectively, and the three elastic elements 40 are positioned near the first, second, and third ends of the second support plate 20, when the drive shafts 52 of the first, second, and third ends of the second support plate 20 move up and down, the three first abutment members 11 are pushed and drive the first support plate 10 to move. This causes the first support plate 10 to pull the three elastic elements 40 to extend and retract. The three elastic elements 40 apply a reaction force to the first adjustment point, the second adjustment point, and the third adjustment point, restricting the movement of the first support plate 10 at the first adjustment point, the second adjustment point, and the third adjustment point, and improving the movement stability of the first support plate 10 at the first adjustment point, the second adjustment point, and the third adjustment point.

[0065] Preferred, such as Figure 1 As shown, the first, second, and third ends of the second support plate 20 form an isosceles or equilateral triangle. This ensures that the first, second, and third adjustment points form an equilateral triangle, making the vertical movement distances of these points similar, thus making it easier to adjust the first support plate 10 to a horizontal position. Furthermore, the equal distances between the first, second, and third adjustment points result in similar pressures from the first support plate 10, improving adjustment efficiency and stability.

[0066] It should be noted that the three drive components 50 of the leveling device 100 correspond to the three first abutment members 11 respectively. During adjustment, the three drive shafts 52 move up and down simultaneously, causing the three adjustment points on the first support plate 10 to move up and down. The first support plate 10 is movably mounted on the second support plate 20 by the elastic member 40, so that the first support plate 10 is restricted by the elastic member 40 after being adjusted to a horizontal position, thereby improving the support stability of the first support plate 10. In other embodiments, the elastic member 40 is used to limit the range of motion of the first support plate 10, and the first support plate 10 is made horizontal by adjusting the three adjustment points of the first support plate 10 up and down, all of which are within the protection scope of this embodiment.

[0067] Example 2

[0068] The present invention also proposes a scanning imaging platform 200, such as Figure 7 and Figure 8As shown, the system includes a support 208, a clamping stage 206, an imaging device 210, and a leveling device 100 as described above. The leveling device 100 is mounted on the support 208, and the clamping stage 206 is mounted on the bearing surface 101 of the leveling device 100. The imaging device 210 is mounted on the support 208 and positioned above the clamping stage 206. Specifically, the support 208 supports the leveling device 100, and the clamping stage 206 is mounted on the bearing surface 101 of the leveling device 100. The leveling device 100 adjusts the levelness of the clamping stage 206 to keep it parallel to the imaging device 210, thereby improving the clarity of the image after the imaging device 210 scans the sample.

[0069] Preferred, such as Figure 8 As shown, the imaging device 210 includes an optical assembly 203, a line scan camera 204, and an objective lens 201. The optical assembly 203 is mounted on the side wall of the support 208, the line scan camera 204 is mounted at the first end of the optical assembly 203, and the objective lens 201 is mounted at the second end of the optical assembly 203. The line scan camera 204 and the objective lens 201 are positioned opposite each other. Specifically, the objective lens 201 magnifies the sample for the first time, and its resolution directly affects the image quality. The optical assembly 203 is used to achieve precise control and adjustment of light to meet the needs of different applications; the optical assembly 203 has the characteristics of adjustability and reusability. The objective lens 201 magnifies the light generated by the sample, the optical assembly 203 is used to adjust the light and reflect or refract it, and the line scan camera 204 is used to scan the light so that the light generated by the sample forms an image.

[0070] Preferred, such as Figure 8 As shown, the imaging device 210 also includes a laser ranging module 205, a first lifting mechanism 202, and a second lifting mechanism 207. The laser ranging module 205 is mounted on the second end of the optical component 203 and is arranged parallel to the objective lens 201. The optical component 203 is mounted on the output end of the first lifting mechanism 202, which is mounted on the upper end of the support 208. The leveling device 100 is mounted on the output end of the second lifting mechanism 207, which is mounted on the lower end of the support 208. Specifically, the first lifting mechanism 202 is used to adjust the position of the optical component 203 on the mounting stage 206, and the second lifting mechanism 207 is used to adjust the position of the mounting stage 206 below the optical component 203, so that the objective lens 201 and the mounting stage 206 are focused, and the light generated on the mounting stage 206 is within the range of reflection or refraction by the optical component 203. In this embodiment, the first lifting mechanism 202 and the second lifting mechanism 207 are existing technologies, consisting of a motor, a lead screw, and a moving block, which will not be described in detail here; in other embodiments, the lifting structure can also achieve up and down movement through other transmission structures.

[0071] In addition, sensor 21 sends the position coordinates of the three sensing elements 54 to laser ranging module 205. The three position coordinates obtained by laser ranging module 205 are inconsistent, that is, the clamping stage 206 and the objective lens 201 are not parallel. By activating the leveling device 100, the three driving elements 51 simultaneously drive the drive shaft 52 to move up and down, so that the six free adjustment points on the first support plate 10 move, so that the clamping stage 206 and the objective lens 201 are parallel. The three position coordinates obtained by laser ranging module 205 are consistent. Laser ranging module 205 feeds back the information that the three position coordinates are consistent to sensor 21, and sensor 21 drives driving element 51 to stop operation.

[0072] The present invention also proposes a leveling method, comprising the following steps:

[0073] Step 1: Start the three drive components 50. The three drive components 51 drive the three drive shafts 52 to move up and down respectively. The three drive shafts 52 push the three first abutment components 11 to move up and down respectively.

[0074] The first support plate 10 moves up and down to pull the elastic element 40 so that the elastic element 40 is in a tensioned state.

[0075] Step 3: The three sensors 21 respectively sense the vertical position values ​​of the three sensing elements 54. When the values ​​sensed by the three sensors 21 are consistent, the three sensors 21 generate an electrical signal, which drives the driving element 51 to stop working.

[0076] By simultaneously adjusting the three drive shafts 52 up and down using the three drive components 50, the first support plate 10 is adjusted to a horizontal position under the constraint of the elastic element 40.
