Description

Technical Field

[0001] This invention relates to the field of biological microscopy, and more specifically, to a multi-position stage for a biological microscope and its operation method. Background Technology

[0002] The stage, also known as the microscope stage, is a support platform in a microscope system that holds the sample and is placed perpendicular to the optical axis. As a key mechanical component of the microscope, the stage has a central aperture to ensure light transmission and is usually equipped with a specimen pusher (slide pusher) and spring clips for holding the specimen.

[0003] In existing microscopes, such as the applicant's earlier application, publication number CN 223742857 U, an electric microscope is disclosed. The stage includes an upper support plate, a lower support plate, and a slide pressing assembly. The lower support plate is connected to a stage connecting rod and to a slider on a guide rail I. The upper support plate is slidably mounted on the lower support plate, and the slide pressing assembly is slidably mounted on the upper support plate, enabling the slide to move back and forth and left and right. A first lead screw and nut pair is provided on the lower support plate, with its output end connected to the upper support plate. A second lead screw and nut pair is provided on the slide pressing assembly, with its output end connected to the upper support plate, enabling electrically controlled slide movement adjustment. Specifically, the slide pressing assembly includes a positioning plate and a clamping plate, with the clamping plate rotatably mounted on the positioning plate. Both the first and second lead screw and nut pairs are electrically connected to a controller for convenient control.

[0004] The existing microscopes described above typically have stages that can only hold one specimen. When observing multiple specimens, it is necessary to frequently tighten and loosen the slide clamping assembly and frequently reset and restart the drive mechanism, which is very inconvenient. Furthermore, the drive mechanism of the microscope's stage is mostly exposed, which not only affects the aesthetics but also makes it susceptible to damage from impacts.

[0005] Therefore, there is an urgent need to develop and design a multi-position stage and operation method for biological microscopes to solve the above-mentioned technical problems. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to address the above-mentioned shortcomings of the prior art. The purpose of the present invention is to provide a multi-position stage for a biological microscope, which can hold a single specimen or multiple specimens at the same time. Each specimen can be adjusted individually, which facilitates subsequent microscope observation of the specimens.

[0007] The second objective of this invention is to provide a method for operating a multi-position stage of a biological microscope, which facilitates specimen observation.

[0008] To achieve the first objective mentioned above, the present invention provides a multi-position stage for a biological microscope, comprising an upper support plate, a middle support plate, and a lower support plate arranged from top to bottom. The upper support plate has an upper elongated oblong hole, the middle support plate has a circular hole, and the lower support plate has a lower elongated oblong hole. The length directions of the upper elongated oblong hole and the lower elongated oblong hole are perpendicular to each other. An L-shaped positioning plate is fixedly installed on the top surface of the upper support plate outside the upper elongated oblong hole. Multiple clamping plates for clamping specimens are rotatably installed on the upper support plate on the opening side of the L-shaped positioning plate. The multiple clamping plates are arranged side by side, and their arrangement direction extends along the length direction of the upper elongated oblong hole. A first driving mechanism is provided between the upper support plate and the middle support plate to drive the upper support plate to move along the length direction of the upper elongated oblong hole, and a second driving mechanism is provided between the middle support plate and the lower support plate to drive the middle support plate to move along the length direction of the lower elongated oblong hole.

[0009] As a further improvement, the long side of the L-shaped positioning plate is parallel to the length direction of the upper elongated hole, and the short side of the L-shaped positioning plate is provided with at least two bosses. The bosses protrude along the length direction of the upper elongated hole, and the protrusion height of the bosses is consistent.

[0010] Furthermore, the clamping plate is V-shaped, and a through hole is provided at one closed end of the clamping plate. A pressure plate is placed on top of the clamping plate, and at least two clamping screws are provided on the pressure plate. One end of the clamping screw passes through the pressure plate and the through hole in sequence and is threaded to the upper support plate. Both sides of the clamping plate are in friction fit with the upper support plate and the pressure plate.

[0011] Furthermore, the opening ends of the clamping plate are respectively provided with a pressing surface and a rotating part, and the rotating part is arranged to be curved upward.

[0012] Furthermore, both the first drive mechanism and the second drive mechanism are lead screw and nut pairs, and the first drive mechanism and the second drive mechanism are respectively installed on adjacent sides of the middle support plate. The nut corresponding to the first drive mechanism is connected to the upper support plate, and the nut corresponding to the second drive mechanism is connected to the lower support plate.

[0013] Furthermore, a proximity switch sensing plate is installed on the nut corresponding to the first drive mechanism and the second drive mechanism, and a proximity switch sensor is provided below one end of the lead screw corresponding to the first drive mechanism and the second drive mechanism. The proximity switch sensor is located on the travel path of the proximity switch sensing plate and is connected to the middle support plate.

[0014] Furthermore, both the first drive mechanism and the second drive mechanism are provided with protective covers on their outer sides, and the protective covers are fixedly connected to the middle support plate through support columns.

[0015] To achieve the second objective mentioned above, the present invention provides a method for operating a multi-position stage of a biological microscope, the method comprising the following steps:

[0016] S1: Arrange multiple specimens side by side on the top surface of the upper support plate along the length of the upper oblong hole, so that one end of the specimen is close to the inside of the L-shaped positioning plate; S2: Rotate the multiple clamping plates one by one to press the other end of the specimen; S3: Start the second drive mechanism to move the middle support plate along the length of the lower elongated hole until the center of the circular hole of the middle support plate is aligned with the center of the lower elongated hole of the lower support plate. S4: Start the first drive mechanism to move the upper support plate along the length of the upper elongated hole until one of the specimens is aligned with the center of the circular hole in the middle support plate, and observe the specimen through the eyepiece; S5: Repeat step S4 to complete the alignment and observation of the other specimens; S6: Reset the second drive mechanism and the first drive mechanism respectively, loosen the clamping plate, remove all specimens, and complete the simultaneous observation of multiple specimens.

[0017] Beneficial effects Compared with the prior art, the advantages of this invention are as follows: 1. The multi-position stage of the present invention, by setting an upper elongated hole and an L-shaped positioning plate on the upper support plate, and setting multiple clamping plates arranged in parallel along the length direction of the upper elongated hole, can place a single specimen or multiple specimens at the same time. Each specimen can be adjusted individually. In addition, with the control of the first driving mechanism and the second driving mechanism, it is convenient for subsequent operation of microscope observation of specimens, making it more convenient to use.

[0018] 2. The multi-position stage of the present invention can protect the first drive mechanism and the second drive mechanism by setting a protective cover on the outside of them. On the one hand, it avoids the problem of them being exposed and easily damaged by bumps and knocks. On the other hand, it can reduce noise to a certain extent and make them more convenient to use.

Detailed Implementation

[0021] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.

[0022] See Figure 1-6 As shown, a multi-position stage for a biological microscope according to the present invention includes an upper support plate 1, a middle support plate 2, and a lower support plate 3 arranged from top to bottom. The upper support plate 1, the middle support plate 2, and the lower support plate 3 can slide relative to each other. An upper elongated waist-shaped hole 4 is provided in the upper support plate 1, and a circular hole 5 is provided in the middle support plate 2. The lower support plate 3 is connected to the body of the microscope and has a lower elongated waist-shaped hole 6. The length directions of the upper elongated waist-shaped hole 4 and the lower elongated waist-shaped hole 6 are perpendicular to each other, so that after moving the middle support plate 2 and the upper support plate 2, the centers of the upper elongated waist-shaped hole 4, the circular hole 5, and the lower elongated waist-shaped hole 6 can be aligned so that the light source can illuminate the specimen 8, thereby enabling the specimen to be observed using the eyepiece. An L-shaped positioning plate 7 is fixedly installed on the top surface of the upper support plate 1 outside the upper oblong hole 4 for positioning the specimen 8. Multiple pressing plates 9 for pressing the specimen 8 are rotatably installed on the upper support plate 1 on one side of the opening of the L-shaped positioning plate 7. The multiple pressing plates 9 are arranged side by side, and their arrangement direction extends along the length direction of the upper oblong hole 4, so that the specimen 8 is pressed one by one onto the L-shaped positioning plate 7. A first driving mechanism 10 is provided between the upper support plate 1 and the middle support plate 2 to drive the upper support plate 1 to move along the length direction of the upper oblong hole 4. A second driving mechanism 11 is provided between the middle support plate 2 and the lower support plate 3 to drive the middle support plate 2 to move along the length direction of the lower oblong hole 6, so as to drive the specimen 8 to move laterally and longitudinally, so that it is aligned with the light source and the eyepiece, so as to clean the specimen 8.

[0023] The long side of the L-shaped positioning plate 7 is parallel to the length direction of the upper elongated hole 4. The short side of the L-shaped positioning plate 7 is provided with at least two protrusions 12. The protrusions 12 are used to contact the specimen, which can effectively reduce the contact area. The protrusions 12 protrude along the length direction of the upper elongated hole 4, and the protrusion height of the protrusions 12 is consistent, ensuring that multiple specimens 8 can be horizontally arranged side by side in the upper support plate 1.

[0024] The clamping plate 9 is V-shaped, with a through hole at its closed end. A pressure plate 13 is placed on top of the clamping plate 9, and at least two clamping screws are provided on the pressure plate 13. One end of each screw passes through the pressure plate 13 and the through hole, and is threaded to the upper support plate 1. The clamping screws clamp the pressure plate 13, ensuring friction fit between both sides of the clamping plate 9 and the upper support plate 1 and the pressure plate 13. The clamping plate 9 can rotate but will not automatically loosen, thus achieving the clamping of the specimen 8. Furthermore, a squeezing surface 91 and a rotating part 92 are respectively provided at the open ends of the clamping plate 9. The squeezing surface 91 is a straight surface, which can better press the specimen, and the rotating part 92 is tilted upwards, making it easier to rotate the clamping plate 9.

[0025] Preferably, in this embodiment, the first drive mechanism 10 and the second drive mechanism 11 are both lead screw and nut pairs, and the first drive mechanism 10 and the second drive mechanism 11 are respectively installed on adjacent sides of the middle support plate 2. The nut corresponding to the first drive mechanism 10 is connected to the upper support plate 1, and the nut corresponding to the second drive mechanism 11 is connected to the lower support plate 3, which can drive the upper support plate 1 and the middle support plate 2 to move respectively. Further, a proximity switch sensing plate 14 is installed on the nut corresponding to the first drive mechanism 10 and the second drive mechanism 11. A proximity switch sensor 15 is provided below one end of the lead screw corresponding to the first drive mechanism 10 and the second drive mechanism 11. The proximity switch sensor 15 is located on the travel path of the proximity switch sensing plate 14 and is connected to the middle support plate 2. When the proximity switch sensor 15 detects the proximity switch sensing plate 14, the motors corresponding to the first drive mechanism 10 and the second drive mechanism 11 stop working, and the upper support plate 1 and the middle support plate 2 move back to their original positions for easy repositioning in the next operation.

[0026] The multi-position stage of the present invention, by setting an upper elongated hole 4 and an L-shaped positioning plate 7 on the upper support plate 1, and setting multiple clamping plates 9 arranged in parallel along the length direction of the upper elongated hole 4, can place a single specimen or multiple specimens at the same time. Each specimen can be adjusted individually. In addition, with the control of the first driving mechanism 10 and the second driving mechanism 11, it is convenient for subsequent operation of microscope observation of specimens, making it more convenient to use.

[0027] Preferably, protective covers 16 are provided on the outer sides of both the first drive mechanism 10 and the second drive mechanism 11. The protective covers 16 are fixedly connected to the middle support plate 2 via support columns 17, serving to protect the drive mechanisms. Furthermore, some sound-absorbing cotton can be provided on the inner wall of the protective covers 16 to reduce noise.

[0028] The multi-position stage of the present invention can protect the first drive mechanism 10 and the second drive mechanism 11 by providing a protective cover 16 on the outside of them. This avoids the problem of them being exposed and easily damaged by bumps and knocks, and also reduces noise to a certain extent, making them more convenient to use.

[0029] A method for operating a multi-position stage of a biological microscope, the method comprising the following steps: S1: Arrange multiple specimens 8 side by side along the length of the upper elongated hole 4 on the top surface of the upper support plate 1, so that one end of the specimen 8 is tightly attached to the inner side of the L-shaped positioning plate 7. S2: Rotate the multiple clamping plates 9 respectively to press the other end of the specimen 8 with the clamping plates 9; S3: Start the second drive mechanism 11 to drive the middle support plate 2 to move along the length of the lower elongated hole 6 until the center of the circular hole 5 of the middle support plate 2 is aligned with the center of the lower elongated hole 6 of the lower support plate 3. S4: Start the first drive mechanism 10, which drives the upper support plate 1 to move along the length of the upper elongated hole 4 until one of the specimens 8 is aligned with the center of the circular hole 5 of the middle support plate 2, and observe the specimen 8 through the eyepiece; S5: Repeat step S4 to complete the alignment and observation of the other 8 specimens; S6: Reset the second drive mechanism 11 and the first drive mechanism 10 respectively, loosen the clamping plate 9, remove all specimens 8, and complete the simultaneous observation of multiple specimens 8.

[0030] The multi-position stage operation method of the present invention is simpler to operate and facilitates specimen observation.

[0031] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of the present invention, and these will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
