Technical Field

[0001] The utility model relates to the technical field of sample shooting, in particular to a shadow-free stereoscopic microscopic shooting object-carrying device capable of continuously switching backgrounds. Background Art

[0002] When a laboratory uses a stereo microscope to photograph insects or seeds, if the specimen is placed on a general loading device, shadows will appear near the specimen in the photographed photos, and these shadows will cause great trouble for post-processing of the photos, such as cutting out the image (removing the background of the target object); at the same time, under a microscope, general background materials such as paper and fiber will be photographed with a fiber structure, which interferes with the photographed target; in addition, different backgrounds should generally be used for specimens of different colors. For example, dark-colored insects generally use a white background, but some light-colored specimens are suitable for a dark background. This results in the need to frequently change background materials of different colors when taking pictures, causing inconvenience to the operator. Utility Model Content

Detailed Embodiment

[0024] The following further describes the present utility model in detail with reference to the drawings and specific embodiments. In the description of the present utility model, the relevant orientation or positional relationship is based on Figure 1 the orientation or positional relationship shown, where "up" and "down" refer to Figure 1 the up and down directions of

[0025] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number or order of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0026] Reference Figure 1 The first embodiment of the present application provides a shadow-free stereoscopic microscopic photography device with continuously switchable backgrounds, comprising a base 1, a rotating shaft 2, a first background plate 3, a second background plate 4, a transparent stage 5, and a positioning column. The rotating shaft 2 is fixed on the base 1. The first background plate 3 and the second background plate 4 are both rotatably arranged directly above the base 1 through the rotating shaft 2. A positioning column is also provided on the rotating shaft 2. The transparent stage 5 is fixed at the end of the rotating shaft 2 and is located directly above the first background plate 3. A preset interval is maintained between the transparent stage 5 and the first background plate 3 through the positioning column. The first background plate 3 and the second background plate 4 can both be horizontally rotated relative to the transparent stage 5 so as to overlap or completely stagger each other. The transparent stage 5 is used to place specimens to be photographed, and the first background plate 3 and the second background plate 4 are used to provide backgrounds of different colors when photographing the specimens. In order to ensure the overall stability of the stereoscopic microscopic photography device, the base 1 and the rotating shaft 2 can be made of heavier metal materials.

[0027] In this embodiment, the working process of the utility model is as follows: the photographer first places the specimen to be photographed on the transparent stage 5. At this time, the background plates of several different colors in the stereoscopic microscope photography device with no shadow and continuously switchable background are all located directly below the transparent stage. The photographer selects the intended color background plate from the background plates of several different colors according to the color of the specimen body. At this time, if the background plate located at the top layer (that is, the first background plate 3 adjacent to the transparent stage 5) is selected, the stage of photographing the specimen can be directly entered. Otherwise, if the background plates selected are other background plates If there is a layer of background disk, those background disks of other colors that are located above the selected background disk of the intended color and are temporarily not needed need to be horizontally rotated along the rotating shaft 2 to be moved away, and then the stage of photographing the specimen can be entered. During the photographing process, if it is necessary to switch to a background disk of another color, it is only necessary to horizontally rotate the current background disk through the rotating shaft 2 to be moved away, reselect the background disk of the intended color, and rotate it through the rotating shaft 2 to be directly under the transparent stage 5 to continue photographing. After the photographing is completed, all the background disks are horizontally rotated back along the rotating shaft 2 to be directly under the transparent stage 5, and then the specimen is removed from the transparent stage.

[0028] It should be noted that, in this embodiment, Figure 1Only two background disks are shown, with the first background disk 3 being a white background disk and the second background disk 4 being a black background disk. The white background disk with a high usage frequency (i.e., the first background disk 3) is arranged adjacent to the transparent stage 5. The specific number of background disks can be determined according to actual needs. Generally, setting background disks in five colors, namely white, black, red, green, and blue, can meet most shooting requirements. Other colors that are often used can also be selected as background disks according to needs to better meet the photographing requirements of different specimens. Further, the background disks of different colors can be formed by pasting colored papers of different colors on a transparent acrylic plate. For example, pasting black paper on a transparent acrylic plate forms a black background disk, and pasting white paper on a transparent acrylic plate forms a white background disk. The background disks of different colors can also be achieved by spraying corresponding color coatings on a transparent acrylic plate. For instance, spraying white or black coatings on a transparent acrylic plate respectively yields a white background disk or a black background disk.

[0029] Further, the positioning post is specifically the first positioning post 6. The first positioning post 6 is of a hollow thin-walled structure, and its inner diameter matches the outer diameter of the rotating shaft 2. The first positioning post 6 is sleeved on the rotating shaft 2. The first preset distance between the transparent stage 5 and the topmost background disk (i.e., the first background disk 3) among several background disks is equal to the height of the first positioning post 6. For example, controlling the height of the first positioning post 6 at 20 mm can keep a 20-mm distance between the bottom of the transparent stage 5 and the topmost background disk (i.e., Figure 1 the first background disk 3 in it). Through such a design, under the limitations of light scattering and the depth of field of the photo, the shadow generated by the specimen itself can be eliminated in the photographed specimen photo. Even further, for convenient replacement, an opening can be provided on one side of the first positioning post 6. During installation, the first positioning post 6 is clamped at the corresponding position of the rotating shaft 2 from the opening.

[0030] As a further improvement of this embodiment, to prevent the specimen from shaking due to the influence of wind during photographing, the transparent stage 5 can be designed in a box shape, specifically including a bottom plate 51 and an edge 52 that protrudes upward along the circumferential direction of the bottom plate 51. The transparent stage can be made of glass or acrylic plate.

[0031] Second Embodiment:

[0032] See Figure 2 , to provide more color illumination backgrounds on the basis of reducing the number of background disks, the second embodiment adds a light source module 8 on the basis of the first embodiment ( Figure 1not shown) and a spacer post 9. The spacer post 9 is provided on the rotating shaft 2. The light source scattering disk 7 is disposed between the second background disk 4 (i.e., the black background disk) and the base 1 through the rotating shaft 2, and maintains a second preset distance through the spacer post 9. The light source module 8 is fixedly provided on the base 1. The light source module 8 is used to provide light sources of different colors when photographing a specimen to be photographed. The light source scattering disk 7 is used to scatter the received light source. The light source scattering disk 7 and the light source module 8 are used in cooperation to provide different color illumination backgrounds for the specimen to be photographed. The height of the spacer post 9 is the second preset distance between the light source scattering disk 7 and the base 1. The height of the spacer post 9 is greater than the height of the light source module 8. Considering the working distance of the microscope objective, it is preferably to control the height of the spacer post 9 between 60-100 mm.

[0033] Further, referring to Figure 4 , the light source module 8 includes a red LED 81, a green LED 82, a blue LED 83, a first switch 84, a second switch 85, a third switch 86, and a power supply 87. The red LED 81, the green LED 82, and the blue LED 83 are respectively connected in parallel to the positive and negative terminals of the power supply 87 through the first switch 84, the second switch 85, and the third switch 86, and can provide monochromatic light sources of red, green, and blue. Using these three monochromatic light sources alone can produce backgrounds of red, green, and blue; using any two of these three monochromatic light sources in combination can also produce backgrounds of yellow, cyan, and magenta, so as to better meet the photographing requirements.

[0034] In this embodiment, referring to Figure 2 , the photographer first places the specimen to be photographed on the transparent stage 5. At this time, both the first background disk 3 and the second background disk 4 in the three-dimensional microscopic photographing stage device without shadow and with continuously switchable background are located directly below the transparent stage 5. If the background color provided by the first background disk 3 or the second background disk 4 can meet the current photographing requirements, the photographing of the specimen can be directly entered; otherwise, the background colors provided by both the first background disk 3 and the second background disk 4 do not meet the current photographing requirements, and both the first background disk 3 and the second background disk 4 need to be moved away. According to the color of the specimen body, the corresponding switch on the light source module 8 is selected to be turned on. For example, if the first switch 84 is turned on, the red LED 81 emits light and can provide a red light source; if the second switch 85 and the second switch 86 are turned on simultaneously, the corresponding green LED 82 and blue LED 83 emit light simultaneously and can provide a cyan light source. After adjusting the required light source, the photographing can be continued. After the photographing is completed, the corresponding switch on the light source module 8 is turned off, and all the background disks are horizontally rotated back to directly below the transparent stage 5 along the rotating shaft 2, and then the specimen is taken away from the transparent stage.

[0035] The light source scattering disk 7 can be specifically obtained by pasting a layer of sulfuric acid paper or soft light cloth on a transparent acrylic plate. The light source scattering disk 7 is used in cooperation with the light source module 8 arranged on the base 1. The light source scattering disk 7 scatters the light source emitted by the light source module 8 on the base 1 to prevent the clear light source points from affecting the background.

[0036] For the convenience of processing, as a further improvement of this embodiment, the outer dimensions of the transparent stage 5, the first background disk 3, the second background disk 4, the light source scattering disk 7 and the base 1 are the same. Further, the transparent stage 5, the first background disk 3, the second background disk 4, the light source scattering disk 7 and the base 1 all include mounting portions, and through holes are provided on the mounting portions. The transparent stage 5, the first background disk 3, the second background disk 4, the light source scattering disk 7 and the base 1 are connected by a rotating shaft 2 passing through the through holes.

[0037] Third Embodiment:

[0038] In order to make the height between the transparent stage 5 and the first background disk 3 adjustable, the third embodiment is based on the second embodiment, see Figure 3 , the positioning post is designed as a second positioning post 10. The second positioning post 10 is generally in a hollow cylindrical shape. The inner diameter of the second positioning post 10 is larger than the outer diameter of the rotating shaft 2. First threaded holes are provided on the circumferential surface of the second positioning post 10. The first threaded holes can be two or three. When the first threaded holes are specifically two, the two first threaded holes can be symmetrically arranged on the circumferential surface of the second positioning post 10. When the first threaded holes are specifically three, the three first threaded holes can be arranged in an array on the circumferential surface of the second positioning post 10. The axis of the first threaded hole is perpendicular to the axis of the second positioning post 10; second threaded holes are symmetrically provided on the end surface of the second positioning post 10, and the axis of the second threaded hole is parallel to the axis of the second positioning post 10. The first threaded hole is used to fix the second positioning post 10 on the rotating shaft 2. Specifically, a screw is passed through the first threaded hole and tightened, so as to fix the second positioning post 10 on the rotating shaft 2; the second threaded hole is used to fix the transparent stage 5 on the end surface of the second positioning post 10. At this time, threaded holes are also opened at the corresponding positions of the transparent stage 5. The screw is passed through the threaded hole of the transparent stage 5 and extended to the second threaded hole and tightened and fixed. Through such a design, the installation position of the second positioning post 10 on the rotating shaft 2 can be adjusted as needed, so as to adjust the height between the transparent stage 5 and the first background disk 3 to better meet the actual needs.
