Description

Technical Field

[0001] The utility model relates to the field of microscopic morphology detection, in particular to a specimen fixing device on an imaging device. Background Art

[0002] The acquisition of digital images under a microscope generally requires magnifying the field of view with an optical microscope and then projecting the image onto a photosensitive chip (such as CCD, COMS, etc.). Therefore, only images of extremely small areas of the specimen can be obtained, and the image quality is highly dependent on the microscope.

[0003] With the development of ultra-high-definition camera technology and the substantial improvement of the resolution of photosensitive chips, it has become possible to place the specimen on the surface of the photosensitive chip for imaging and obtain the largest range of images of the specimen. The research in related fields is also getting more and more popular at home and abroad.

[0004] When using a photosensitive chip to directly acquire a specimen image, the specimen target object needs to be as close to the photosensitive chip as possible, and the distance between the two needs to be minimized to reduce light scattering, so as to improve image clarity. The specimen device is required to be able to carry the specimen as close to the camera device as possible. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems and provide a specimen fixing device on an imaging device, which can make the specimen close to the imaging device.

[0006] To achieve the above objectives, the technical solution adopted by the utility model is a specimen fixing device on an imaging device, which includes a loading portion placed between a light source and a camera device, the loading portion moves along a line between the light source and the camera device, the loading portion is set as a transparent area within the camera range of the camera device, and through the movement of the loading portion, the specimen can be conveniently placed on the loading portion while being brought close to the camera device.

[0007] Furthermore, the loading part is connected to the loading platform, and the loading platform moves along the direction of the line between the light source and the camera device, and the loading part is separated from the loading platform to further facilitate the operation of the staff.

[0008] Furthermore, a turntable is provided on the stage, and the rotation axis of the turntable is in the same direction as the line between the light source and the camera device. A support that cooperates with the loading part is provided on the turntable. When the specimen is placed on the loading part, the loading part is rotated out from between the light source and the camera device to facilitate the operation of the staff, while also playing a role in protecting the light source and the camera device.

[0009] Furthermore, the stage is provided with a linear drive mechanism for driving the connection part to move, and the movement direction of the connection part is perpendicular to the line between the light source and the camera device. The connection part cooperates with the loading part, and when the specimen is placed on the loading part, the loading part is moved out from between the light source and the camera device to facilitate the operation of the staff, while also protecting the light source and the camera device.

[0010] Furthermore, a through hole is provided on the object-carrying part to avoid interference of the imaging effect due to factors such as refraction of light and impurities on the object-carrying part to the greatest extent.

[0011] Furthermore, a countersunk hole is provided at the upper end of the through hole.

[0012] The beneficial effects of the utility model are as follows: the object-carrying part is far away from the camera device, so that the staff can lay the filter membrane carrying the specimen on the object-carrying part conveniently, and then the object-carrying part moves toward the camera device to improve the imaging effect.
