Description

Technical Field

[0001] This application belongs to the field of fluorescence detection and sensing technology, and particularly relates to a fluorescence detector device that is easy to install and adjust. Background Art

[0002] X-ray fluorescence analysis technology is an efficient and mature multi-element analysis method that can perform non-destructive testing on samples and qualitatively and quantitatively provide element composition and its spatial distribution information. This technology has significant advantages such as non-destructiveness, high sensitivity, simultaneous detection of multiple elements, and simple sample preparation. Therefore, it has been widely used in fields such as geology, archaeology, environmental science, biology, and materials science. With the rapid development of related technologies such as biotechnology, microfluidics technology, and artificial intelligence, the demand for fluorescence detection technology in fields such as microfluidics, biomedical detection, biomolecule detection, drug screening, environmental monitoring, biochemical warfare agent detection, and bioaerosol detection is increasing day by day.

[0003] However, existing fluorescence detection schemes and devices are often too complex, bulky, and difficult to assemble. Currently, on the market, fluorescence detectors are usually installed inside the experimental cavity to ensure an internal vacuum environment or other inert gas environments. Choosing an overly large experimental cavity will result in a bulky overall device and excessive floor space, while choosing a too small one will limit the adjustment range of the fluorescence detector and make it difficult to adjust and install the device, making it difficult to meet the needs of rapid on-site testing, and the cost is also relatively high. To solve these problems, we need to further optimize fluorescence detection technology, improve its performance, reduce its complexity and cost, so as to better meet the needs of various fields. Summary of the Utility Model

[0004] To solve the problems mentioned above, such as difficult installation, complex operation during experiments, inconvenient quick adjustment for different experiments, and small spatial range for adjusting the fluorescence detector, a fluorescence detector device that is easy to install and adjust is proposed. It is installed outside the cavity while ensuring a pure and interference-free optical path, obtaining a larger operating space and more convenient installation and adjustment effects.

[0005] To achieve the above and other related purposes, the technical solutions provided by the present utility model are as follows:

Among them, the positioning plate is installed below the T-shaped plate to ensure the positioning of the overall device. The T-shaped plate is fixedly connected to the experimental cavity. A support plate is installed on the T-shaped plate to support the second translation stage. A third adapter plate is installed on the second translation stage for connecting to the first translation stage. A first adapter plate is installed on the first translation stage for connecting to the support plate. The support plate is installed with a first adapter plate to support the fluorescence detector and the pipeline connection assembly. When the first translation stage and the second translation stage move, the fluorescence detector moves accordingly, facilitating more accurate reception of optical path information, and the corrugated pipe ensures that the optical path is not affected by external factors.

[0009] In an embodiment of the present application, the pipeline connection assembly is divided into two upper and lower fixing blocks. There is an arc-shaped notch on the lower side of the upper fixing block, and an arc-shaped notch on the upper side of the lower fixing block. Threaded holes are drilled on the two fixing blocks to facilitate the connection and fixation of the two fixing blocks. The arc-shaped notch positions and sizes of the two fixing blocks are the same. The corrugated pipe is placed at the arc-shaped notch on the lower fixing block and then fixed by the upper fixing block.

[0010] In one embodiment of the present application, the support assembly includes a first adapter plate, a support plate, a second adapter plate, a third adapter plate, a support plate, a positioning plate, and a T-shaped plate.

The support plate is provided with holes for threaded connection with the second translation stage, a step is provided at the motor position of the second translation stage to facilitate the installation of the second translation stage, and holes for threaded connection with the T-plate are provided below the support plate; holes for threaded connection with the support plate, the positioning plate and the experimental cavity are provided on the T-plate, and the shorter side of the T-plate is connected and fixed to the experimental cavity. The positioning plate is pre-installed under the T-plate, and when the T-plate is installed, it supports the side of the bottom plate of the experimental cavity to assist in positioning the T-plate, and at the same time supports the T-plate to prevent deformation of the T-plate.

[0011] The benefits of the utility model are:

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0018] In the description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0019] As Figure 1 、 Figure 2 shown, there are threaded through holes on the positioning plate 11, which are threadedly connected to the T-shaped plate 12 through bolts. After the positioning plate 11 is threadedly connected to the T-shaped plate 12, the T-shaped plate 12 is threadedly connected to the cavity. During the connection, positioning is performed through the positioning plate 11. The installation positions of the positioning plate 11 and the T-shaped plate 12 are reasonably designed and connected according to the edge dimensions of different cavities and the dimensions of the T-shaped plate 12. The horizontal surface of the T-shaped plate 12 is threadedly connected to the cavity edge. The supporting plate 10 is installed on the T-shaped plate 12 through threaded connection. A second translation stage 9 is installed on the supporting plate 10, and the supporting plate 10 and the second translation stage 9 are threadedly connected. One side of the supporting plate 10 is stepped, which is convenient for the installation and placement of the motor of the second translation stage 9 when installing the second translation stage 9. The step height difference is reasonably designed according to the size of the motor of the second translation stage 9. In this embodiment, the motor of the second translation stage 9 faces the cavity. A third adapter plate 8 is installed on the second translation stage 9, and the two are threadedly connected. Through holes for threaded connection are reserved on the third adapter plate 8. Holes for threaded connection with the second translation stage 9 and holes for threaded connection with the first translation stage 7 are provided on the third adapter plate 8. The first translation stage 7 is installed on the third adapter plate 8, and then the third adapter plate 8 is installed on the second translation stage 9. Holes for threaded connection with the second adapter plate 6 are provided on the second translation stage 9. Holes for threaded connection with the support plate 5 are also drilled on the second adapter plate 6. Figure 1The support plate 5 shown in the figure is one of the embodiments. The shape of the support plate 5 is not limited, and it plays a role in supporting the first adapter plate 4 and the components above the first adapter plate 4 stably. The support plate 5 is threadedly connected to the second adapter plate 6, and two support plates 5 are threadedly connected to the first adapter plate 4. A fluorescence detector 1 is placed above the first adapter plate 4. The fluorescence detector 1 can be fixedly connected by threads or directly placed on the first adapter plate 4 according to different models. The pipeline connection assembly 5 is installed on the first adapter plate 4. The pipeline connection assembly 2 is responsible for connecting the corrugated pipe 3 and the fluorescence detector 1 to ensure that the light path propagation is not affected by external factors. A fixed flange 13 is installed at one end of the corrugated pipe 3 connected to the cavity to ensure the airtightness after installation.

[0020] As Figure 3 shown, during the experiment, the fluorescence detector 1 can move in the X and Y directions through the first translation stage 7 and the second translation stage 9, which is convenient for faster and more accurate optical experiments. During the movement of the fluorescence detector 1, the corrugated pipe 3 is driven to move accordingly. At the same time, the fixed flange 13 and the pipeline connection assembly 2 ensure the tight connection at both ends of the corrugated pipe 3 and the airtightness of the overall device. When replacing the fluorescence detector 1 of different models or other detectors in the later stage, the pipeline connection assembly 2 can be directly disassembled and the fluorescence detector 1 can be replaced, which is more convenient and faster. On this basis, according to different experimental requirements, the lifting table and translation stages with different position distances can be replaced according to the size of the cavity.
