Description

Technical Field

[0001] This utility model relates to the field of optics, and in particular to a camera assembly for observing and photographing crystal seeds. Background Technology

[0002] In fields such as chemistry, materials science, pharmaceuticals, and biotechnology, the formation, growth, and morphology of seed crystals are key research subjects in the crystal growth process. Real-time, clear observation and recording of seed crystals are of paramount importance for understanding crystallization mechanisms, controlling crystal quality, and optimizing production processes.

[0003] Currently, the common method for observing seed crystals mainly uses a regular digital camera with a macro lens. However, while this method is portable, it is difficult to achieve stable and accurate focusing. During operation, the camera usually needs to be manually or with the aid of a simple stand to fix it, making it impossible to ensure a constant distance between the camera and the sample. Even slight shaking can cause focusing failure, making it difficult to obtain clear and consistent seed crystal images. Utility Model Content

[0004] The purpose of this invention is to provide a camera assembly for observing and photographing seed crystals, which solves the technical problem of difficulty in obtaining clear and consistent seed crystal images in the traditional method of using a digital camera with a macro lens.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a camera assembly for observing and photographing crystal seeds, the camera assembly for observing and photographing crystal seeds comprising: Cargo base platform; A lifting and adjusting bracket is mounted on the cargo base platform; A camera is mounted on the lifting and adjusting bracket, and a data cable for transmitting data is connected to the camera; A microscope head, wherein the microscope head is mounted on the lens at the bottom of the camera; The light source is located at the bottom of the microscope head.

[0006] In one embodiment, a positioning plate is provided on the upper surface of the carrier base platform. The positioning plate is circularly arranged around the carrier base platform, and the center of the positioning plate is located directly below the camera.

[0007] In one embodiment, the lifting and adjusting bracket includes: An outer rod, the bottom of which is fixed to the cargo base platform, and the outer rod is provided with a sliding groove perpendicular to the cargo base platform; The inner rod is slidably disposed in the groove of the outer rod, and a rack structure is provided on one side of the inner rod. The camera is fixed to the top of the inner rod. An adjusting rod is rotatably mounted on the outer rod. The outer surface of the adjusting rod is provided with a gear structure, and the adjusting rod meshes with a rack structure on the inner rod.

[0008] In one embodiment, an adjustment handle is provided on the outside of the adjustment rod.

[0009] In one embodiment, the camera is a CCD camera.

[0010] In one embodiment, the microscope head includes: An eyepiece assembly is fitted and fixed to the bottom of the camera. The eyepiece assembly includes an outer eyepiece sleeve and an eyepiece disposed inside the eyepiece sleeve. The outer surface of the eyepiece sleeve is provided with external threads. An objective lens assembly, comprising an external objective lens sleeve and an objective lens disposed within the objective lens sleeve, wherein the objective lens sleeve is threadedly fitted onto the eyepiece sleeve.

[0011] In one embodiment, the light source unit includes: A number of LED beads are evenly distributed at the bottom of the microscope head; A power supply is built into the microscope head and is connected to the lamp beads via wires.

[0012] The above-described technical solutions in the embodiments of this utility model have at least the following technical effects or advantages: The camera assembly for seed observation and imaging provided in this embodiment integrates the camera, microscope lens, light source, and lifting and adjusting bracket onto a single base platform, forming a complete and dedicated observation and imaging system. Compared to the complex combination of external cameras on traditional microscopes, this device has a compact structure, high degree of integration, requires no cumbersome installation and debugging, and is very convenient to operate, greatly improving the efficiency of observation and imaging.

[0013] Furthermore, by setting up a lifting and adjusting bracket, especially using a gear and rack adjustment mechanism (adjusting rod and inner rod), smooth and precise vertical lifting and lowering can be achieved, thereby completing the focusing process. This method avoids the shaking caused by manual holding or simple brackets, ensuring precise control of the distance between the camera and the sample, and resulting in more stable and clearer images.

[0014] A ring-shaped positioning plate is installed on the sample carrier platform to guide users to quickly and accurately place sample containers such as petri dishes directly below the lens. This ensures that the framing center remains consistent for each observation, facilitating repeated observation and effective comparison of different samples or the same seed crystal at different times.

[0015] Finally, this invention integrates the light source directly into the bottom of the microscope head, with multiple LEDs arranged around it to provide uniform, shadow-free coaxial or ring-shaped illumination for the observation area. This built-in, sample-close light source design avoids interference from external light, and combined with a dedicated microscope head and CCD camera, ensures that high-resolution, high-definition images of the seed crystals can be captured.

[0023] Please see Figures 1 to 5 This application provides a camera group of 3 for seed crystal observation and imaging, including a base platform 1, a lifting and adjusting bracket 2, a camera 3, a microscope head 4, and a light source 5. The lifting and adjusting bracket 2 is mounted on the base platform 1; the camera 3 is mounted on the lifting and adjusting bracket 2 and is connected to a data cable 7 for data transmission; the microscope head 4 is mounted on a lens at the bottom of the camera 3; and the light source 5 is located at the bottom of the microscope head 4.

[0024] The core structure of this invention includes a base platform 1, a lifting and adjusting bracket 2 mounted on the platform, a camera 3 mounted on the bracket, and a microscope head 4 and a light source 5 connected sequentially below the camera 3. These five parts together constitute an integrated observation and imaging system. The camera 3 is connected to an external computer or display device via a data cable 7 for real-time image display, imaging, and data storage. By integrating the core components required for observation and imaging into one unit, a compact and dedicated device is formed. Compared to existing technologies that temporarily assemble separate devices such as the camera 3, microscope, and light source, this solution has a robust structure, simplified operation, and significantly improves ease of use and imaging stability.

[0025] Optionally, the load-bearing base platform 1 can be a rectangular or circular flat plate with a large weight and bottom area. For example, it can be made of solid steel plate, aluminum alloy block or high-density engineering plastic with counterweight to ensure that the center of gravity of the whole device is low and the stability is good, so that it will not easily shake or tip over during operation.

[0026] Based on this, a positioning piece 6 is provided on the upward-facing side of the platform. This positioning piece 6 is arranged in a circular manner around the center point directly below the lens of camera 3.

[0027] The positioning piece 6 can be a standard circular frame formed on the platform by screen printing or etching; it can also be a shallow annular groove machined on the surface of the platform; or it can be three or more protrusions or positioning blocks distributed along a standard circumference (e.g., 90 mm in diameter to fit a standard petri dish).

[0028] When the positioning piece 6 is a groove or a protrusion, its material should be the same as the platform or a wear-resistant engineering plastic. Its inner diameter can be preset according to the size of commonly used seed culture containers (such as petri dishes, crystallization plates), such as 60mm, 90mm, 120mm, etc.

[0029] The application of positioning plate 6 solves the problem of positional uncertainty caused by arbitrary sample placement. Operators can quickly and accurately place sample containers (such as petri dishes) into the preset observation area, ensuring that the center of the field of view is consistent for each observation. This is particularly important for seed growth studies that require long-term, multi-batch comparative observation, ensuring the repeatability and reliability of the data.

[0030] In one embodiment, the lifting and adjusting bracket 2 includes an outer rod 21, an inner rod 22, and an adjusting rod 23. The bottom of the outer rod 21 is fixed to the load base platform 1, and a groove perpendicular to the load base platform 1 is provided on the outer rod 21. The inner rod 22 is slidably disposed within the groove of the outer rod 21, and a rack structure is provided on one side of the inner rod 22. The camera 3 is fixed to the top of the inner rod 22. The adjusting rod 23 is rotatably disposed on the outer rod 21, and a gear structure is provided on the outer surface of the adjusting rod 23, which meshes with the rack structure on the inner rod 22.

[0031] The lifting and adjusting bracket 2 is crucial for achieving precise focusing. It includes an outer rod 21 fixed to the base platform 1 and an inner rod 22 that can slide within the outer rod 21. A groove perpendicular to the platform is formed on the outer rod 21, serving as a guide rail for the inner rod 22. A rack structure is machined on one side of the inner rod 22, while the adjusting rod 23 is rotatably mounted on the outer rod 21, with a gear structure meshing with the rack in the portion extending into the outer rod 21. The camera 3's mounting base is located on top of the inner rod 22. For ease of operation, an adjusting handle 24 is also fitted onto the outside of the adjusting rod 23.

[0032] Specifically, the outer rod 21 and the inner rod 22 are preferably made of lightweight, high-strength aluminum alloy or stainless steel. Low-friction gaskets such as polytetrafluoroethylene (PTFE) can be added to the mating surfaces of the slide and the inner rod 22 to ensure smooth, uninterrupted sliding.

[0033] The modules of gears and racks can be designed to be small to achieve high-precision transmission ratios. For example, rotating the adjustment handle 24 one full revolution results in a vertical displacement of only 1-2 mm for the inner rod 22 (i.e., camera 3), thus achieving micron-level fine focusing.

[0034] The adjustment handle 24 is preferably a knob with knurling or covered with anti-slip rubber to increase friction and facilitate fine turning by the user. Furthermore, a locking screw can be added to the adjustment rod 23, which can be tightened after focusing to fix the height of the camera 3 and prevent focus shift due to accidental contact or gravity.

[0035] The gear and rack meshing transmission design serves as a labor-saving and precise transmission method. It converts the rotational motion of the handle into smooth vertical linear motion of the camera, making operation effortless, adjustment highly accurate, and enabling easy and clear focusing. Compared to simple stands that rely on friction for fixation, its stability and repeatability are significantly improved.

[0036] In one embodiment, camera 3 is a CCD camera 3. Specifically, an industrial-grade CCD camera 3 is selected, with a resolution of 5 megapixels or higher, to capture the microscopic morphological details of the seed crystal. The interface of camera 3 can adopt a standard C / CS interface, which facilitates standardized connection with microscope head 4.

[0037] The cable connecting the camera 3 can be a USB 3.0 data cable or an HDMI high-definition cable, enabling high-speed image transmission and ensuring real-time preview without delay on a computer or monitor.

[0038] In one embodiment, the microscope head 4 includes an eyepiece assembly 41 and an objective lens assembly 42. The eyepiece assembly 41 is fitted and fixed to the bottom of the camera 3. The eyepiece assembly 41 includes an outer eyepiece sleeve 411 and an eyepiece 412 disposed within the eyepiece sleeve 411. The outer surface of the eyepiece sleeve 411 is provided with external threads. The objective lens assembly 42 includes an outer objective lens sleeve 421 and an objective lens 422 disposed within the objective lens sleeve 421. The objective lens sleeve 421 is threaded onto the eyepiece sleeve 411.

[0039] Specifically, the eyepiece 412 in the eyepiece group 41 can be a standard 10X magnification. The objective lens 422 in the objective lens group 42 can be designed to be interchangeable, providing objective lenses 422 with different magnifications such as 2X, 4X, and 10X, to meet the observation needs of different sized seed crystals.

[0040] The sleeves of eyepiece 412 and objective lens 422 are preferably made of black aluminum alloy with an anodized surface to reduce stray light reflection. The threaded connection design is not only for assembly, but its rotation process itself can also serve as a means of fine-tuning the focus, supplementing the coarse focusing of the lifting bracket. The lenses themselves may be coated with an anti-reflective coating (AR coating) to improve light transmittance and image contrast.

[0041] The modular, threaded connection design offers several advantages: firstly, it provides flexible magnification, allowing users to change the overall magnification by replacing different objective lens groups 42; secondly, it offers adjustable focal length, enabling fine-tuning of the distance between the objective lens 422 and the sample by rotating the objective lens sleeve 421, thus achieving more precise focusing. It provides the necessary optical magnification for observing tiny seed crystals.

[0042] In one embodiment, the light source unit 5 includes a plurality of LED beads 51 and a power supply 52. ​​The LED beads 51 are evenly distributed at the bottom of the microscope head 4; the power supply 52 is built into the microscope head 4 and is connected to the LED beads 51 through wires.

[0043] Optionally, the LED chips 51 are preferably high-brightness white LED chips 51, and the number can be between 8 and 24. Their optimal arrangement is in a ring array to form a ring light source.

[0044] The built-in power supply 52 can be a button battery or a small lithium battery for ultimate portability, installed in the reserved compartment of the objective lens sleeve 421; or it can be powered by an external USB interface through a thin power supply cable 52, running parallel to the data cable 7 of the camera 3.

[0045] In addition, the light source unit 5 can be equipped with a brightness adjustment knob or switch, allowing users to adjust the illumination intensity according to the reflective characteristics of the sample to obtain the best imaging effect and avoid overexposure.

[0046] By integrating the light source directly into the bottom of the lens and designing it in a ring shape, uniform and blind-spot-free illumination can be provided to the sample from directly above the lens. This illumination method greatly reduces the generation of lateral shadows, clearly revealing the crystal's outline and surface details. The built-in power supply 52 design makes the entire device more concise, avoiding interference and constraints from external power supply cables 52, enhancing the overall integrity and portability of the device.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
