Description

Technical Field

[0001] The present invention relates to the technical field of microscopic imaging equipment, and in particular to a microscopic imaging device and a microscopic imaging method. Background Art

[0002] A microscope is an optical instrument composed of one lens or a combination of multiple lenses, which is mainly used to magnify tiny objects so that they can be seen by the naked eye. However, the focal length of a traditional microscope is limited, and it is impossible to observe objects that are larger or smaller than expected. This means that some objects are too large or too small to be seen with an optical microscope. If you want to view the object, you can only replace a microscope of other specifications or replace the condenser tube. However, the condenser of a traditional microscope is troublesome to replace, which increases the cost and time of use. For this reason, we propose a microscopic imaging device and a microscopic imaging method. Summary of the invention

[0010] The displacement groove near one side of the installation tube is through-opened, and a gear bar is installed on the outer side of the clamping block installed at the through displacement groove, and the gear bar slides inwardly and is clamped in the through groove.

[0011] Preferably, each of the condensing lens barrels corresponds to a focal length range, so the focal lengths of the fixed mirror and the displacement mirror in each condensing lens barrel correspond to each other.

[0012] Preferably, the rotating rod is inserted into the mounting frame, and a bearing is provided at the connection between the rotating rod and the mounting frame; the mounting cylinder and the driven gear head form a rotating structure.

[0028] Example:

[0029] See also Figure 1-5 , the present invention provides the following technical solutions: a microscopic imaging device and a microscopic imaging method, comprising a microscope 10 and a condenser adjustment device 20;

[0030] A light source 101 is installed at the rear side of the microscope 10, a three-way observation head 102 and an eyepiece tube 103 are installed at the top of the microscope 10, a condenser adjustment device 20 is installed in the middle of the microscope 10, the three-way observation head 102 is located directly above the condenser adjustment device 20, and the condenser adjustment device 20 is located directly above the stage 104;

[0031] The condenser adjustment device 20 is composed of a driving structure and a rotating structure. The driving structure includes a mounting frame 201 and a lens-changing driving motor 202. The mounting frame 201 is fixed to one side of the microscope 10 by screws. The mounting frame 201 is in a C-shape with a short top and a long bottom. The lens-changing driving motor 202 is installed on the upper part of the mounting frame 201 by screws. The driving end of the lens-changing driving motor 202 extends downward, and a driving gear head 203 is installed at the bottom of the driving end.

[0032] The bottom of the mounting frame 201 is rotatably mounted with a mounting cylinder 204, the top of the mounting cylinder 204 is provided with a rotating rod extending upward, the rotating rod is inserted into the mounting frame 201, and a bearing is provided at the connection between the rotating rod and the mounting frame 201; a driven gear head 205 is sleeved on the rotating rod, and the driven gear head 205 and the driving gear head 203 are meshed with each other;

[0033] A plurality of condensers 30 are evenly arranged on the outside of the mounting tube 204. The condenser 30 is composed of a condenser tube 301, a fixed mirror 302 and a displacement mirror 304. The fixed mirror 302 is fixed on the top of the condenser tube 301, and the displacement mirror 304 is installed in the inner cavity of the condenser tube 301. Each condenser tube 301 corresponds to a focal length interval, so the focal lengths of the fixed mirror 302 and the displacement mirror 304 in each condenser tube 301 correspond to each other.

[0034] Four displacement grooves 303 are diagonally provided at the middle and lower part of the inner wall of the focusing lens barrel 301, and four clamping blocks 305 are diagonally provided at the outer side of the displacement mirror 304. The clamping blocks 305 are slidably inserted in the displacement grooves 303, so that the displacement mirror 304 moves up and down under the cooperation of the clamping blocks 305 and the displacement grooves 303;

[0035] The middle and lower part of the inner wall of the installation tube 303 is evenly provided with through slots 204-1, and the inner wall of the installation tube 303 is evenly provided with mirror moving driving motors 204-2, and the transmission end of the mirror moving driving motor 204-2 is provided with an adjusting gear 204-3, and one side of the adjusting gear 204-3 is inserted into the adjacent through slot 204-1;

[0036] The displacement groove 303 near one side of the installation tube 204 is through-opened, and a gear bar 306 is installed on the outer side of the clamping block 305 installed at the through displacement groove 303, and the gear bar 306 slides inwardly and is clamped in the through groove 204-1; the inner side of the gear bar 306 is provided with gear teeth, and the gear bar 306 is meshed with the adjustment gear 204-3 inwardly through the gear teeth;

[0037] The mirror moving drive motor 204-2 drives the gear bar 306 to move up and down by adjusting the gear 204-3, and the gear bar 306 drives the displacement mirror 304 to move synchronously. In this way, the distance between the fixed mirror 302 and the displacement mirror 304 can be adjusted, so that the focal length of the condenser tube 301 can be adjusted; and the mirror changing drive motor 202 drives the driving gear head 203 to rotate, and the driving gear head 203 drives the mounting tube 204 to rotate through the meshing driven gear head 205. When the mounting tube 204 rotates, the condenser 30 with different focal lengths can be replaced.

[0038] Working principle: the lens-changing driving motor 202 drives the driving gear head 203 to rotate. Since the driving gear head 203 and the driven gear head 205 are meshed with each other, the rotation of the driving gear head 203 drives the driven gear head 205 to rotate. The driven gear head 205 is sleeved on the rotating rod of the mounting tube 204. The rotating rod is connected to the mounting frame 201 through a bearing, so that the mounting tube 204 can rotate at the bottom of the mounting frame 201.

[0039] The transmission end of the moving mirror driving motor 204-2 is equipped with an adjusting gear 204-3, and one side of the adjusting gear 204-3 is inserted into the through slot 204-1 of the inner wall of the mounting tube 204; four displacement slots 303 are diagonally opened in the middle and lower part of the inner wall of the focusing lens tube 301, and four clamping blocks 305 are diagonally arranged on the outer side of the displacement mirror 304, wherein the displacement slot 303 close to the side of the mounting tube 204 is through-opened, and a gear bar 306 is installed on the outer side of the clamping block 305 at the displacement slot 303, and the gear bar 306 slides inwardly and is clamped in the through slot 204-1, and meshes with the adjusting gear 306.

[0040] When the mirror driving motor 204-2 is working, the gear bar 306 is driven to move up and down by adjusting the gear 204-3. Since the gear bar 306 is connected to the clamping block 305 of the displacement mirror 304, the displacement mirror 304 is driven to move up and down synchronously under the cooperation of the clamping block 305 and the displacement groove 303, thereby changing the distance between the fixed mirror 302 and the displacement mirror 304, so as to achieve the purpose of adjusting the focal length of the focusing lens tube 301;

[0041] A plurality of condensers 30 corresponding to different focal length ranges are evenly arranged on the outside of the mounting tube 204. The rotation of the mounting tube 204 enables the replacement of condensers with different focal lengths. The principle is as follows: the fixed mirror 302 in each condenser 30 uses a convex lens with a different focal length, and the displacement mirror 304 also uses a convex lens with a different focal length. When the displacement mirror 304 and the fixed mirror 302 change their relative positions, the focal length of the condenser 30 can be adjusted within a certain range, which is very convenient.
