Description

Technical Field

[0001] The utility model relates to the technical field of scanning, and particularly relates to a glass slide positioning and scanning module. Background Art

[0002] In life sciences, medical research, and clinical diagnosis, microscopic imaging observation of glass slide samples is a crucial technical means. The traditional microscope operation method is usually to first find the area of interest and then adjust the magnification to observe the details. However, in actual work, especially when dealing with large samples or when a comprehensive analysis of the sample is required, obtaining an overall view of the sample first is crucial for determining the observation area and understanding the global structure of the sample.

[0003] Most microscope systems currently available on the market focus on providing high-resolution local magnified images to meet the need for fine analysis of sample details. However, in actual use, users often first need a macroscopic understanding of the sample, including basic information such as the size, shape, and color distribution of the sample, in order to select a suitable observation area. This need for the macroscopic structure of the sample is particularly prominent in the research of pathology, cytology, and other related disciplines.

[0004] Therefore, how to design a positioning and scanning module that can quickly obtain an overall view of the glass slide sample, is easy to operate, and has a reasonable cost has become an urgent technical problem to be solved. Summary of the Invention

Detailed implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

[0020] As Figures 1 to 3 shown, a slide 12 positioning and scanning module includes a camera 2, an upper light source assembly 4, a lower light source assembly 7, and a positioning plate 5. A positioning buffer member 6 is provided on the positioning plate 5. When scanning the slide 12, the slide 12 is placed on the slide clip 11, and one end of the slide clip 11 contacts the positioning buffer member 6.

[0021] In this utility model, the slide clip 11 is installed on the moving device 10, and the moving device 10 is used to drive the slide clip 11 to move. When photographing and scanning the slide 12, place the slide 12 on the slide clip 11, and then drive the slide 12 to move through the moving device 10 until one end of the slide clip 11 abuts against the positioning buffer member 6, achieving the positioning of the slide 12 in the horizontal direction; the slide 12 buffer member can play a good buffering role, reduce the physical impact when the slide clip 11 abuts, and prevent the slide 12 from being damaged. When the slide 12 moves in place, the upper light source assembly 4 is located above the slide 12, and the lower light source assembly 7 is located below the slide 12. The sample on the slide 12 is photographed and scanned by the camera 2; when photographing and scanning, the use of the light source assembly can be selected according to actual needs; when the lower light source assembly 7 is turned on, the light generated by the lower light source assembly 7 passes through the slide 12 from bottom to top, enhancing the contrast and details of the sample, especially for transparent or semi-transparent samples such as tissue sections and cells; bottom lighting can highlight the structure and internal features of the sample, making it easier to observe and capture images. When the upper light source assembly 4 is turned on, the light generated by the upper light source assembly 4 irradiates the surface of the sample from top to bottom, illuminating the surface of the sample so that the camera 2 can clearly capture the surface details of the sample. At the same time, in order to facilitate the information management and tracking of the slide samples, barcode information is usually set on the slide 12. Through the irradiation of the upper light source assembly 4, the barcode information on the slide 12 can be clearly photographed, facilitating the subsequent access, analysis, and tracking of the slide sample images.

[0022] Among them, the model of the camera 2 is MER2-630-60U3C-L, which has the characteristics of stability, durability, high efficiency, and simple maintenance. The moving device 10 can adopt a linear module.

[0023] The camera 2 is installed on the camera fixing seat 1, and the upper light source fixing plate 3 is provided on the camera fixing seat 1. The upper light source assembly 4 is installed below the upper light source fixing plate 3.

[0024] The upper light source assembly 4 includes an upper light source 4-1, a first diffuser plate 4-2, and a first connecting column 4-3. The first diffuser plate 4-2 is located below the upper light source 4-1. Both the upper light source 4-1 and the first diffuser plate 4-2 are connected to the first connecting column 4-3, and the first connecting column 4-3 is fixedly connected to the upper light source fixing plate 3. The first diffuser plate 4-2 is used to disperse the light of the upper light source 4-1, achieving uniform illumination of the sample, reducing light spots or shadows, and helping the sample to show more details.

[0025] The upper light source 4-1 is in a circular ring shape. In this embodiment, the upper light source 4-1 is an LED dot matrix light source. The LED dot matrix light source can provide strong and uniform light, and has the characteristics of high brightness, long life, and stability.

[0026] The lower light source assembly 7 and the positioning plate 5 are both mounted on the base 8. The lower light source assembly 7 includes a lower light source 7-1, a second diffuser plate 7-2, and a second connecting column 7-3. The lower light source 7-1 and the second diffuser plate 7-2 are both connected to the first and second connecting columns 7-3. The second diffuser plate 7-2 is located above the lower light source 7-1, and the second connecting column 7-3 is fixedly connected to the base 8. The second diffuser plate 7-2 is used to disperse the light of the lower light source 7-1, achieve uniform illumination of the sample, reduce light spots or shadows, and help the sample show more details.

[0027] In this embodiment, the lower light source 7-1 is an LED dot matrix light source, which can provide strong and uniform illumination and has the characteristics of high brightness, long life and stability.

[0028] The base 8 includes a height-increasing cushion block 8 - 1 and a positioning cushion plate 8 - 2 arranged on the upper end of the height-increasing cushion block 8 - 1 .

[0029] The positioning buffer component 6 includes a fixed block 6-1 disposed on the positioning plate 5, a guide hole 6-2 is disposed on the fixed block 6-1, a movable plug 6-3 is slidably connected in the guide hole 6-2, the movable plug 6-3 extends from one end of the guide hole 6-2, and a spring 6-4 is disposed between the movable plug 6-3 and the other end of the guide hole 6-2. One end of the slide clamp 11 contacts the movable plug 6-3, and the spring 6-4 acts as a buffer to the slide clamp 11, thereby reducing the impact on the slide clamp 11.

[0030] The utility model has the following advantages: The utility model obtains an overall view of the glass slide sample through the camera 2, helping the user to quickly view the overall picture of the sample, which is very important for understanding the overall layout and positioning of the sample. The macroscopic image obtained by scanning can easily mark specific areas or points of interest on the sample, which is convenient for the user to perform detailed scanning and analysis at high magnification later; in the macroscopic image, the user can select and confirm the area that needs to be scanned in detail, optimize the settings and range of high-resolution scanning, and improve scanning efficiency. The macroscopic image of the glass slide sample obtained by this device is used as a panoramic record of the sample, which helps to manage and archive the overall information of the sample, and is convenient for subsequent reference and analysis. And through the overall view, it is possible to check whether the glass slide 12 is damaged, dirty or has other problems that affect the magnified scanning, and eliminate the problems in time to avoid negative impacts on the subsequent detailed scanning of the sample.
