Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to an automatic imaging device for detection. Background Technology
[0002] Tunable filter technology achieves selective transmission of different spectral bands by adjusting the transmission characteristics of the filter. This technology allows switching between different spectral bands within the same imaging system, thereby acquiring multispectral information of the target object. Therefore, tunable filter technology is widely used in fields such as spectral analysis and biomedical imaging. For example, in spectral analysis, by adjusting the transmission characteristics of the filter, the absorption, reflection, or fluorescence properties of a sample in different spectral bands can be measured; in biomedical imaging, tunable filter technology can be used to achieve multispectral imaging of tissue sections, improving diagnostic accuracy.
[0003] Tunable filters are typically composed of multilayer thin films, liquid crystal layers, or micro / nano structures, and their transmission characteristics are adjusted by changing external conditions (such as voltage and temperature). Imaging systems integrate tunable filters to achieve switching and imaging across different spectral bands. However, certain drawbacks also exist, including:
[0004] 1. The operation is complex. Existing imaging systems typically include multiple parameters, such as exposure time, gain, and white balance. Setting these parameters can be quite complicated, and users need to have certain professional knowledge and experience to correctly set these parameters to obtain high-quality images.
[0005] 2. Poor stability: Existing imaging system technologies may be affected by environmental factors such as temperature, humidity, and light, leading to unstable system performance. In harsh environments, the imaging system may malfunction or the image quality may degrade. Some imaging system hardware components may have design flaws or manufacturing problems, resulting in a high failure rate. Hardware failures may cause system shutdown or image quality damage, affecting normal use by users.
[0006] 3. The logic is complex. Existing imaging systems typically contain complex image processing algorithms, such as image enhancement, denoising, and edge detection. The implementation of these algorithms may involve a large amount of mathematical calculations and programming work, which increases the complexity and development cost of the system.
[0007] 4. High cost: Existing imaging systems typically require high-quality hardware components, such as high-resolution cameras, lenses, and sensors. These hardware components are expensive, which increases the overall cost of the imaging system. Utility Model Content

Detailed Implementation
[0030] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0031] like Figure 1-6 As shown, an automated imaging device for biomedical sample detection is disclosed. It is easy to operate, highly stable, simple in structure, and low in manufacturing cost. The automated imaging device includes an imaging connection structure 10, with an imaging camera 20 connected to its upper end. The imaging connection structure 10 facilitates the transmission of fluorescence emitted by fluorescent proteins or other fluorescent markers on the biological sample being detected to the imaging camera 20. The imaging camera 20 captures and records image information, which is then transmitted to a computer or other display device via a data transmission interface for user viewing and analysis.
[0032] In this application, the imaging connection structure 10 includes a base plate 101, a first mounting base 102, and a second mounting base 103 connected sequentially from bottom to top. Both the first mounting base 102 and the second mounting base 103 have vertically penetrating cavities. The base plate 101 has an imaging hole 107 communicating with the cavity of the first mounting base 102. Fluorescence emitted from biological samples, which is easily detected, enters the first mounting base 102 and the second mounting base 103 through the imaging hole 107 and is ultimately transmitted to the imaging camera 20. The cavity of the first mounting base 102 contains a first dichroic mirror 108 and a beam splitter 109. One side of the imaging connection structure 10 is connected to an imaging light source structure 30 corresponding to the first dichroic mirror 108, and the other side of the imaging connection structure 10 is connected to an autofocus system 40 corresponding to the beam splitter 109. The second mounting base 103 contains a first filter 110, a first lens group 111, and a plane mirror 112 arranged sequentially from bottom to top. The plane mirror 112 is positioned corresponding to the imaging camera 20. The first dichroic mirror 108 filters the fluorescence emitted from the biological sample, allowing only light of a specific wavelength to pass through. The beam splitter 109 separates the light passing through the first dichroic mirror 108, allowing a portion to pass through for capture by the imaging camera 20, while the remaining portion is reflected to the autofocus system 40. The autofocus system 40 automatically adjusts the focus of the imaging device to ensure clear imaging by the imaging camera 20. The imaging light source structure 30 emits excitation light to excite fluorescence emitted by fluorescent proteins or other fluorescent markers on the biological sample. The first filter 110 filters out light, removing non-specific wavelengths and retaining only the desired wavelength. The first lens group 111 focuses the light, concentrating the dispersed light phase. The plane mirror 112 reflects the light focused by the first lens group 111 back to the imaging camera 20, facilitating the capture of fluorescence emitted from the biological sample by the imaging camera 20.
[0033] In the scheme of this application, the first lens group 111 includes a first convex lens 1111 and a second convex lens 1112. The first convex lens 1111 is disposed below the second convex lens 1112. The convex surfaces of the first convex lens 1111 and the second convex lens 1112 are both set downwards. The two convex lenses can better collect and focus light.
[0034] In this application, the first mounting base 102 has a protruding second connector 105 on its side. The second connector 105 is used to connect with the imaging light source structure 30. By inserting the second connector 105 into the imaging light source structure 30, a quick connection between the first mounting base 102 and the imaging light source structure 30 can be achieved. The connection is reinforced by locking the second connector 105 into the third mounting base 301 and the first mounting base 102 of the imaging light source structure 30. The second connector 105 has a third convex lens 117 and a fourth convex lens 118. The convex surfaces of the third convex lens 117 and the fourth convex lens 118 are arranged opposite each other. The third convex lens 117 is used for focusing, and the fourth convex lens 118 is used for straightening. The third convex lens 117 and the fourth convex lens 118 achieve the effect of collimation and light collection, which can effectively emit the light from the light source 302 onto the biological sample to be tested.
[0035] In this application, the first dichroic mirror 108, the beam splitter 109, and the plane mirror 112 are all tilted to facilitate light reflection and transmission, ensuring that light is emitted along a predetermined optical path. The plane mirror 112 is connected to an end cap 113, which covers the upper end of the second mounting base 103, facilitating the installation or replacement of the plane mirror 112. The first dichroic mirror 108 is connected to a first fixing bracket 115, and the beam splitter 109 is connected to a second fixing bracket 116. The first fixing bracket 115 and the second fixing bracket 116 are inserted into the first mounting base 102. The first dichroic mirror 108 is first installed on the first fixing bracket 115, and then the first fixing bracket 115 is inserted into the first mounting base 102. The beam splitter 109 is first installed on the second fixing bracket 116, and then the second fixing bracket 116 is inserted into the first mounting base 102, facilitating the installation and replacement of the first dichroic mirror 108 and the beam splitter 109.
[0036] In this application, the second mounting base 103 has a lens barrel 114 for fixing the first filter 110 and the first lens group 111, which facilitates the installation and fixing of the first filter 110 and the first lens group 111, while ensuring that the light is distributed in a circular pattern, making it easier for the circular lens of the imaging camera 20 to capture it. The upper end of the second mounting base 103 has a first connector 104, which facilitates the connection between the second mounting base 103 and the imaging camera 20 and is locked with a nut. The side of the first mounting base 102 has a connection hole 106 for mounting the autofocus system 40, which facilitates the light split by the beam splitter 109 to be emitted into the autofocus system 40, thereby achieving focusing on the automatic imaging device, and facilitates the connection between the autofocus system 40 and the first mounting base 102, which is reinforced from the side with screws.
[0037] In this application, the imaging light source structure 30 includes a third mounting base 301. The third mounting base 301 is used to connect two light sources 302 to the first mounting base 102. The two light sources 302 can be switched on and off as needed to achieve switching of light sources, which can meet the imaging requirements of different application scenarios. This not only improves the flexibility of the automatic imaging device, but also reduces the cost and time for users to replace the light sources 302. The third mounting base 301 is provided with a cavity that communicates with the light sources 302 and the imaging connection structure 10, ensuring that the light emitted by the light sources 302 can be transmitted into the imaging connection structure 10 and emitted onto the biological sample to be detected through the imaging connection structure 10. The cavity of the third mounting base 301 is provided with a tilted second dichroic mirror 303, which is used to transmit or reflect the light that is needed from the light emitted by the two light sources 302, while the rest of the unwanted light is intercepted. The two surfaces of the second dichroic mirror 303 correspond to one light source 302, thereby ensuring that the light emitted by the corresponding light source 302 can be emitted. The second dichroic mirror 303 is connected to the third mounting bracket 304, that is, the second dichroic mirror 303 is installed on the third mounting bracket 304, and then the third mounting bracket 304 is inserted into the third mounting base 301, which facilitates the installation and replacement of the second dichroic mirror 303.
[0038] In the solution of this application, the two light sources 302 are a blue light source and a UV light source, respectively. By controlling the switching of the two light sources 302, the switching between the blue light source and the UV light source can be realized, which can be applied to different detection needs.
[0039] Based on the above scheme, the light source 302 includes a fourth mounting base 3021. The fourth mounting base 3021 has a through cavity, within which a light source module 3022, a second lens group 3023, and a second filter 3024 are arranged sequentially at intervals. The second filter 3024 is positioned close to the third mounting base 301. The light source module 3022 generates excitation light, which is focused and straightened by the second lens group 3023. The second filter 3024 filters out non-specific wavelengths of light, retaining only the desired wavelength. The fourth mounting base 3021 is used to mount the light source module 3022, the second lens group 3023, and the second filter 3024. This allows the light source 302, composed of the light source module 3022, the second lens group 3023, and the second filter 3024, to be integrated into an independent modular structure, facilitating the installation and replacement of the light source 302 and simplifying the structure of the automatic imaging device.
[0040] Based on the above scheme, the second lens group 3023 includes a hemispherical lens 30231, a fifth convex lens 30232, and a sixth convex lens 30233 arranged sequentially at intervals. The hemispherical lens 30231 is positioned close to the light source module 3022, and the convex surfaces of the hemispherical lens 30231, the fifth convex lens 30232, and the sixth convex lens 30233 are all oriented towards the position of the second filter 3024. The hemispherical lens 30231 is used to collect light, while the fifth convex lens 30232 and the sixth convex lens 30233 are used to converge the divergent light and convert it into direct light. Through the three lenses of the second lens group 3023, the utilization of the light emitted by the light source module 3022 can be maximized.
[0041] Based on the above solution, a heat sink 3025 is provided on the side of the light source module 3022 away from the second lens group 3023. This effectively conducts the heat generated by the light source module 3022 to the outside, ensuring that the light source module 3022 can work for a long time. This, in turn, ensures that the light source mechanism can maintain stable performance under long-term operation and extends the service life of the automatic imaging device. The heat sink 3025 is preferably a copper block, as copper has excellent thermal conductivity and can conduct the heat generated by the light source module 3022 to the external heat dissipation system, ensuring that the operating temperature of the light source module 3022 remains within a reasonable range and improving its service life. A thermally conductive medium, such as thermally conductive adhesive or a thermally conductive pad, is provided between the light source module 3022 and the heat sink 3025 to ensure efficient heat transfer.
[0042] In this application, the autofocus system 40 is an LAF focusing system, which is connected to a nano-translation stage, enabling high-precision focusing and ensuring the imaging effect of the imaging camera 20. A reinforcing plate 401 is connected between the autofocus system 40 and the imaging connection structure 10 to strengthen the connection between the autofocus system 40 and the imaging connection structure 10, ensuring the focusing stability of the autofocus system 40.
[0043] In this application, the working principle of the automatic imaging device is as follows: one of the two light sources 302 in the imaging light source structure 30 is energized and emits light. The light is converted into straight light by the hemispherical lens 30231, the fifth convex lens 30232, and the sixth convex lens 30233. This straight light is filtered by the second filter 3024, which blocks non-specific wavelengths of light, retaining only the required wavelengths. Then, part of these rays are further intercepted by the second dichroic mirror 303, and then converted to the fourth convex lens 118 and the third convex lens 117. After being focused and straightened by the fourth convex lens 118 and the third convex lens 117, the light is then intercepted and converted by the first dichroic mirror 108, finally becoming the excitation light source required for the biological sample. When light from a light source shines on a biological sample, it excites fluorescent proteins or other fluorescent markers on the sample to emit fluorescence. This fluorescence is emitted and enters the cavity of the large first mounting base 102. Then, it is filtered by the first dichroic mirror 108 and shines onto the beam splitter 109. The beam splitter 109 reflects a portion of the light to the autofocus system 40, which then begins focusing. The remaining portion of the light passing through the beam splitter 109 is filtered by the first filter 110, then focused and straightened by the first lens group 111, and finally emitted through the plane mirror 112 to the imaging camera 20. The imaging camera 200 captures and records the image information, and finally transmits the image information to a computer or other display device through a data transmission interface, thus completing the automatic imaging of the automatic imaging device.
[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
