Description

Technical Field

[0001] This utility model relates to the field of microscope observation technology, and specifically to an auxiliary rotation device for a microscope stage. Background Technology

[0002] Currently, when examining mold on microscope plates, existing stages cannot stably hold the plates, making changing the field of view cumbersome and requiring readjustment of the focus knobs, which is time-consuming. Furthermore, traditional slides can only hold a limited number of samples, necessitating frequent slide changes, thus reducing examination efficiency and accuracy. Therefore, this application is submitted. Utility Model Content

[0003] The purpose of this invention is to provide an auxiliary rotating device for a microscope stage. By setting a circular slide and placing it in a rotating disk mounted above a vacuum chuck, the microscopic sample on the circular slide rotates with the rotating disk, thereby improving microscopic examination efficiency and solving the problems in the prior art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0005] An auxiliary rotating device for a microscope stage includes a stage with a light-transmitting aperture, and a rotating disk above the stage for rotating a circular glass slide.

[0006] Alternatively, a vacuum suction cup is provided between the stage and the rotating disk, a sleeve is provided at the center of the vacuum suction cup, and an insert rod is provided at the center of the rotating disk inside the sleeve.

[0007] Alternatively, the vacuum suction cup has a plurality of evenly distributed grooves on its surface, a fixing rod is provided in the groove, and a roller is sleeved on the outer periphery of the fixing rod.

[0008] Alternatively, the top of the roller is higher than the surface of the vacuum suction cup and in contact with the bottom surface of the rotating disk.

[0009] Alternatively, the number of rollers is at least three.

[0010] Alternatively, the outer diameter of the vacuum chuck is larger than the outer diameter of the rotating disk.

[0011] Alternatively, the roller may be made of rubber.

[0012] Alternatively, the roller may be installed in the same direction as the diameter of the vacuum suction cup.

[0013] Alternatively, the top of the rotating disk is provided with a mounting groove adapted to a circular glass slide, and the circular glass slide is located in the mounting groove.

[0014] Further optionally, the vacuum suction cup is provided with a through hole one that coincides with the light-transmitting hole, and the rotating disk is provided with multiple through holes two, wherein when any of the through holes two rotates to the position of the through hole one, the two are connected to each other.

[0015] The advantages of this invention are as follows: A vacuum suction cup, a rotating disk, and a circular glass slide are respectively arranged above the stage. The circular glass slide is located in the mounting slot of the rotating disk and rotates under the assembly of the insert rod and roller. The rotating disk can be rotated as needed to change the field of view, thereby improving work efficiency. At the same time, the traditional square glass slide is designed as a circle, which increases the number of samples that can be placed for microscopic examination and eliminates the need to frequently change the glass slide for microscopic examination, thereby improving microscopic examination efficiency.

[0024] Example 1

[0025] Embodiment 1 of this utility model is an auxiliary rotating device for a microscope stage 1, including a stage 1 with a light-transmitting hole 10, and a rotating disk 3 above the stage 1 for rotating a circular glass slide 4.

[0026] Reference Figures 1 to 4 This application primarily utilizes a circular slide 4 placed within a rotating disk 3. The rotating disk 3 rotates above the stage 1, causing the circular slide 4 to rotate and altering the field of view above it. This eliminates the need for readjusting the coarse and fine adjustment knobs, allowing for convenient adjustment. Simultaneously, the rotating disk 3 has a perforated area that overlaps with the light-transmitting hole 10 of the stage 1. This allows the light source at the bottom of the stage 1 to pass through the light-transmitting hole 10 and the perforated area, allowing observation of the sample via the transparent circular slide 4. Furthermore, the circular slide 4 increases the number of samples that can be examined compared to a traditional square slide, improving examination efficiency.

[0027] It should be noted that the circular slide 4 and the traditional square slide are made of the same material and have the same thickness, which is existing technology and will not be described in detail here.

[0028] In some preferred embodiments, a vacuum suction cup 2 is provided between the stage 1 and the rotating disk 3, a sleeve 23 is provided at the center of the vacuum suction cup 2, and an insertion rod 31 located inside the sleeve 23 is provided at the center of the rotating disk 3.

[0029] Reference Figure 2 The function of the vacuum suction cup 2 is twofold: firstly, to provide room for the rotation of the rotating disk 3, and secondly, to ensure that the rotating disk 3 is fixed above the stage 1 during rotation. At the same time, the vacuum suction cup 2 uses the vacuum negative pressure to firmly adhere it to the surface of the stage 1, thus ensuring the integrity of the stage 1 without the need for other limiting components on the stage 1. It also facilitates disassembly and assembly, improving practicality.

[0030] Furthermore, the rotating disk 3 is rotated by the movement of the insert rod 31 within the sleeve 23. Specifically, the rotating disk 3 is rotated manually, and the insert rod 31 below the rotating disk 3 rotates within the sleeve 23. After rotating to a certain position, the observation position of the microscopic sample is changed. At the same time, the glass slide and the rotating disk 3 are fixed by the fixing component of the stage 1 (which is the prior art) before the sample is observed.

[0031] In some preferred embodiments, the surface of the vacuum suction cup 2 is provided with a plurality of evenly distributed grooves 20, and a fixing rod 21 is provided in the groove 20. A roller 22 is sleeved on the outer periphery of the fixing rod 21. The top of the roller 22 is higher than the surface of the vacuum suction cup 2 and contacts the bottom surface of the rotating disk 3.

[0032] Specifically, the roller 22 inside the vacuum suction cup 2 contacts the bottom of the rotating disk 3. When the rotating disk 3 is manually rotated, the roller 22 inside the vacuum suction cup 2 rotates, so that the rotating disk 3 is subjected to uniform force during rotation. At the same time, the insertion rod 31 is directly inserted into the inside of the sleeve 23, which facilitates disassembly and replacement of rotating disks 3 of different specifications.

[0033] In some preferred embodiments, the number of rollers 22 is at least three. The minimum number is limited to three to ensure uniform force distribution when the rotating disk 3 rotates on the vacuum chuck 2, so that the microscopic samples of the circular glass slides 4 on the rotating disk 3 are at the same level, preventing tilting that would cause different observation levels.

[0034] In some preferred embodiments, the outer diameter of the vacuum suction cup 2 is larger than the outer diameter of the rotating disk 3. This facilitates manual rotation of the rotating disk 3, and a handle (not shown in the accompanying drawings) can also be provided on the outer periphery of the rotating disk 3 for convenient rotation.

[0035] In some preferred embodiments, the roller 22 is made of rubber. Using rubber reduces processing costs and also reduces wear on the rotating disk 3 during rotation, thus extending the service life of the device.

[0036] In some preferred embodiments, the roller 22 is installed in the same direction as the diameter of the vacuum suction cup 2. This is done so that the rotating disk 3 can better drive the circular glass slide 4 to rotate above the vacuum suction cup 2.

[0037] In some preferred embodiments, the top of the rotating disk 3 is provided with an assembly groove 30 adapted to the circular glass slide 4, and the circular glass slide 4 is located in the assembly groove 30.

[0038] Specifically, an assembly groove 30 is provided on the surface of the rotating disk 3. When rotating, it helps to prevent the circular glass slide 4 from detaching from the rotating disk 3, thus preventing the separation of the microscopic examination sample and the resulting sample waste.

[0039] In some preferred embodiments, the vacuum suction cup 2 is provided with a through hole 24 that coincides with the light-transmitting hole 10, and the rotating disk 3 is provided with a plurality of through holes 32. When any of the through holes 32 rotates to the position of the through hole 24, the two are connected to each other.

[0040] Reference Figure 2 and Figure 3 The vacuum suction cup 2 is fixed above the stage 1. The through hole 24 provided therein is the same size as the light transmission hole 10, so it does not affect the light source passing through the stage 1. At the same time, the rotating disk 3 is provided with multiple through holes 32. Multiple sample marking areas with the same center as the through holes 32 can be set on the surface of the circular glass slide 4. Multiple microscopic samples are placed in the sample marking areas respectively. Thus, during the rotation of the rotating disk 3, the samples in the sample marking areas to be observed can be rotated to the positions corresponding to the through holes 32, through holes 24 and light transmission holes 10 for observation, thereby improving the microscopic examination speed.

[0041] The working principle of this utility model is as follows: A vacuum suction cup 2, a rotating disk 3, and a circular glass slide 4 are respectively set above the stage 1. The circular glass slide 4 is located in the mounting groove 30 of the rotating disk 3 and rotates under the assembly of the insertion rod 31 and the roller 22. The rotating disk 3 is rotated as needed to change the field of view, thereby improving work efficiency. At the same time, the traditional square glass slide is designed as a circle, which increases the number of samples that can be placed for microscopic examination and eliminates the need to frequently change the glass slide for microscopic examination, thereby improving the efficiency of microscopic examination.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of the present utility model and within the spirit and principles of the present utility model shall still fall within the protection scope of the present utility model.
