Description

Technical Field

[0001] The utility model relates to the field of microscopic imaging, in particular to an oil mirror wiping device. Background Art

[0002] In the field of microscopic imaging, digital slide scanners or microscopes are commonly used. Among them, digital slide scanners are a clinical inspection instrument that is mainly used to digitize pathological slides so that doctors can perform remote diagnosis and research. It has the characteristics of high resolution, can scan pathological slides and retain subtle cell structures and tissue morphology, and provide clear images. The microscope is an instrument used to observe microscopic objects that are invisible to the naked eye, and it is a symbol of human entry into the atomic age. The microscope is mainly composed of one or more lenses, which use light to pass through the sample to produce images. It can magnify objects so that people can see tiny details that cannot be observed by the naked eye. When performing microscopic imaging and digital slide scanning, high-power objective lenses are used with cedar oil for scanning observation. The high-power objective lens has a high magnification and a small aperture NA, so the light entering the lens barrel is relatively limited. It is necessary to drip cedar oil with a refractive index (n=1.515) between the objective lens and the glass slide to increase the light entering the oil lens, increase the brightness of the field of view, and improve the imaging quality. After using the oil objective lens, the experimenter usually uses lens cleaning paper containing xylene to wipe the cedar oil remaining on the objective lens to keep the lens clean. At present, the oil objective lens is mostly wiped manually, and the experimenter is inevitably in direct contact with xylene, which has a great impact on the health of the experimenter. Utility Model Content

[0003] The utility model aims to provide an oil immersion mirror wiping device, aiming to improve the problem that experimenters need to manually use xylene to wipe the oil immersion mirror, which has a great impact on their health.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The locking piece is arranged on the slice clamp and is located at the other end of the pressing cover plate, and the locking piece limits the pressing cover plate and the oil wiping paper.

[0008] Furthermore, a hook-shaped bending portion is provided at the other end of the oil-wiping paper, and the hook-shaped bending portion is bent upward from the bottom of the other end of the pressing cover plate to the top of the other end of the pressing cover plate.

[0009] Furthermore, the locking member includes a shaft mounting portion and a limiting portion fixed to the top of the shaft mounting portion, the limiting portion is rotatably arranged on the slice clamp through the shaft mounting portion, and the limiting portion abuts against the top of the hook-shaped bending portion and the pressing cover plate.

[0010] Furthermore, a raising protrusion protruding upward is arranged on the top surface of the other end of the clamping cover plate, and the raising protrusion is located on one side of the rotating shaft mounting portion.

[0011] Furthermore, a mounting groove is provided on the slicing clamp, and the pressing cover plate is arranged in the mounting groove.

[0012] Furthermore, a support platform is fixed in the installation groove, and the top surface of the support platform and the bottom surface of the oil-wiping paper are pressed against each other.

[0031] Example

[0032] Please refer to Figure 1 and Figure 2As shown, this embodiment provides an oil lens wiping device, including a slice clamp 1, a pressing cover plate 2, oil wiping paper 3 and a locking member 4. One end of the pressing cover plate 2 is rotatably arranged on the slice clamp 1 through a rotating shaft. A mounting channel 201 is provided in the middle of the pressing cover plate 2, and a mounting shaft 202 is provided at one end of the mounting channel 201. One end of the oil wiping paper 3 is wound around the mounting shaft 202, and the other end of the oil wiping paper 3 extends toward the other end of the pressing cover plate 2. The locking member 4 is arranged on the slice clamp 1 and is located at the other end of the pressing cover plate 2. The locking member 4 limits the pressing cover plate 2 and the oil wiping paper 3. That is, the mounting shaft 202 is arranged at one end of the pressing cover plate 2 away from the locking member 4, and the oiling paper 3 is detachably arranged on the mounting channel 201 through the mounting shaft 202 and the locking member 4. In the process of wiping the lens, automatic wiping is achieved by adjusting the positional relationship between the slice clamp 1 and the lens, thereby preventing the experimenter from contacting the oiling paper 3 for a long time and protecting the experimenter's personal safety. At the same time, the oiling paper 3 is spread flat on the mounting channel 201, thereby effectively increasing the contact area between the oiling paper 3 and the lens and achieving a better wiping effect.

[0033] The other end of the oil-wiping paper 3 is provided with a hook-shaped bending portion 301, which is bent upward from the bottom of the other end of the pressing cover plate 2 to the top of the other end of the pressing cover plate 2. The mounting shaft 202 limits one end of the oil-wiping paper 3, and the hook-shaped bending portion 301 limits the other end of the oil-wiping paper 3. The mounting shaft 202 and the hook-shaped bending portion 301 jointly tighten the oil-wiping paper 3 to ensure full contact with the lens during the lens wiping process, thereby achieving a better wiping effect.

[0034] In this embodiment, the locking member 4 includes a shaft mounting portion 401 and a limiting portion 402 fixed to the top of the shaft mounting portion 401. The limiting portion 402 is rotatably arranged on the slice clamp 1 through the shaft mounting portion 401, and the limiting portion 402 abuts against the top of the hook-shaped bending portion 301 and the pressing cover plate 2. The limiting portion 402 rotates through the shaft. During the wiping process, the limiting portion 402 rotates to the top of the hook-shaped bending portion 301 and the pressing cover plate 2 to abut against the two, so as to limit the oil wiping paper 3 and the pressing cover plate 2. During the process of replacing and installing the oil wiping paper 3, the limiting portion 402 rotates to separate from the hook-shaped bending portion 301 and the pressing cover plate 2, so that the pressing cover plate 2 and the oil wiping paper 3 can rotate freely, thereby realizing the replacement and installation of the oil wiping paper 3. Similarly, the locking member 4 can also be provided with a magnetic device. For example, the magnetic device is arranged at the bottom of the other end of the pressing cover plate 2. The hook-shaped bending portion 301 passes through the bottom of the pressing cover plate 2 and bends upward. During the process of the magnetic device magnetically fixing the pressing cover plate 2, the oil wiping paper 3 is also fixed at the same time, thereby achieving a limiting effect between the oil wiping paper 3 and the pressing cover plate 2.

[0035] In this embodiment, a protrusion 203 protruding upward is provided on the top surface of the other end of the pressing cover plate 2, and the protrusion 203 is located on one side of the rotating shaft mounting portion 401. The protrusion 203 raises the height of the free end of the hook-shaped bending portion 301, so that the contact between the hook-shaped bending portion 301 and the bottom surface of the limiting portion 402 is closer, so that the oil-wiping paper 3 has better stability during the wiping process, and the oil-wiping paper 3 is prevented from being offset during the wiping process, which affects the wiping effect.

[0036] The slicing clamp 1 is provided with a mounting groove 101, and the pressing cover plate 2 is arranged in the mounting groove 101. Specifically, a rotating shaft 204 is inserted into one end of the pressing cover plate 2, and a corresponding plug-in rotating groove 102 is provided on the inner side wall of the mounting groove 101. Both ends of the rotating shaft 204 are respectively inserted into the two plug-in rotating grooves 102, so that one end of the pressing cover plate 2 can be turned over, which is convenient for installing the oil-wiping paper 3.

[0037] A support platform 5 is fixed in the mounting groove 101, and the top surface of the support platform 5 and the bottom surface of the oil-wiping paper 3 are pressed against each other. The support platform 5 supports the oil-wiping paper 3 to ensure that the oil-wiping paper 3 is in close contact with the lens during the wiping process, thereby improving the wiping effect and avoiding the presence of a gap between the lens and the oil-wiping paper 3 during the wiping process. In this embodiment, the support platform 5 is a flexible support platform 5, and the specific support platform 5 is a rubber platform. The same support platform 5 can be a support platform 5 of other flexible materials. The flexible support platform 5 reduces the friction between the oil-wiping paper 3 and the lens, thereby reducing the damage to the lens caused by the oil-wiping paper 3 during the wiping process. Similarly, a felt pad or other flexible cushion layer can be set on the support platform 5 to reduce the softness of the top of the support platform 5.

[0038] In this embodiment, a plurality of slice placement positions 103 arranged in sequence are provided on the slice clamp 1, slices 6 are placed in the slice placement positions 103, and the mounting groove 101 is located at the tail end of the slice placement positions 103 arranged in sequence. Specifically, the number of slices 6 placed is six, and the six slice placement positions 103 are arranged in a row, and the mounting groove 101 is located on one side of the sixth slice placement position 103. In the process of observing the slices 6, the first to the sixth slices are observed in sequence, and the wiping work is performed after the sixth slice 6 is observed. The wiping work is at the tail end of the observation work, which is in line with the actual experimental process. In this embodiment, the support platform 5 raises the oiling paper 3 so that the top surface of the slice 6 and the top surface of the oiling paper 3 are on the same horizontal plane. The height of the oiling paper 3 is too high, which causes damage to the lens during the translation process after observing the slice 6.

[0039] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
