Description

Technical Field

[0001] The present invention relates to the technical field of microscope mounting platforms, and in particular to a microscope mounting platform for simplifying the calibration of optical elements. Background Art

[0002] In the field of microscopy, especially in automated and digital microscopy, a common structure is to directly connect the microscope camera to the lens barrel to ensure the stability and accuracy of the imaging optical path. This forms an integrated optical element, which is then mounted as a whole on the main frame or platform of the microscope to ensure that the camera's photosensitive element is aligned with the optical axis of the lens barrel.

[0003] However, this integrated installation method presents drawbacks during equipment maintenance, repair, or upgrades. Specifically, because the microscope camera is fixed to the lens barrel, replacing or repairing any individual component (for example, upgrading only the camera for higher resolution or replacing a damaged lens barrel) requires the operator to completely disassemble the entire camera lens barrel assembly from the equipment.

[0004] This adds unnecessary steps, increases the workload for maintenance personnel, and makes the entire process time-consuming and inefficient. Furthermore, after replacement and reinstallation, the alignment of the entire optical system is completely disrupted, necessitating a complex global recalibration. This not only requires extremely high operator skills but also significantly increases assembly errors, thus affecting the measurement accuracy and long-term reliability of the equipment.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be described clearly and completely in the drawings in the specification of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0020] In order to better understand the present application, the above content will be described in detail in combination with specific embodiments.

[0021] Please refer to the drawings in the specification of the present application Figure 1 - the drawings in the specification of the present application Figure 6 The embodiment of the present application provides a microscope mounting platform for simplifying optical element calibration, which comprises: A base plate 2 is mounted on the frame 1, with a microscope camera 4 and a lens barrel 5 provided on the top and bottom of the base plate 2 respectively; a floating flange ring 3 is mounted in the middle of the base plate 2, with the lens of the microscope camera 4 located on one side of the middle of the floating flange ring 3, and the side of the lens barrel 5 close to the microscope camera 4 is located on the other side of the middle of the floating flange ring 3, and the floating flange ring 3 is used to limit the lens of the microscope camera 4 and the lens barrel 5 to remain coaxial; a positioning and tightening assembly 6 is located on the side of the base plate 2 close to the lens barrel 5, and is used to position and tighten the lens barrel 5.

[0022] In this embodiment, the lens barrel 5 can be positioned and fixed by using the positioning and tightening assembly 6, and the microscope camera 4 and the lens barrel 5 can be separated by the floating flange ring 3. Therefore, when one of the microscope camera 4 and the lens barrel 5 is replaced, it is avoided that both the microscope camera 4 and the lens barrel 5 need to be removed. For example, when the microscope camera 4 needs to be replaced, it can be directly removed from the floating flange ring 3, thereby avoiding the need to remove the lens barrel 5. When the lens barrel 5 needs to be replaced, it is only necessary to remove the lens barrel 5 from the positioning and tightening assembly 6 and then install the new lens barrel 5. The microscope camera 4 only needs to be positioned and tightened, thereby avoiding the need to remove the microscope camera 4, thereby significantly improving the maintainability and long-term stability of the equipment. Since the replacement of any component does not require touching another calibrated component, the introduction of new alignment errors due to unnecessary disassembly is fundamentally avoided. After the microscope camera 4 (or the lens barrel 5) is replaced, the original precise position of the lens barrel 5 (or the microscope camera 4) is completely retained. This makes maintenance work no longer require tedious global recalibration of the entire optical path system, greatly shortening the downtime of the equipment for maintenance.

[0023] Please see the attached Figure 3 -Attached Figure 5 The positioning and tightening assembly 6 includes a tightening block 601 and a positioning block 602. The positioning block 602 is connected to the base plate 2 by bolts. The tightening block 601 is connected to the positioning block 602 by bolts, and the lens barrel 5 is located between the positioning block 602 and the tightening block 601.

[0024] In this embodiment, the tightening block 601 can be installed on one side of the positioning block 602 by using bolts, and since the positioning block 602 is pre-installed on one side of the substrate 2 by the bolts, when installing the lens barrel 5, the positioning block 602 can be used to limit and guide the position of the lens barrel 5, thereby achieving the positioning of the lens barrel 5. Subsequently, the distance between the tightening block 601 and the positioning block 602 can be reduced by installing the tightening block 601, and the lens barrel 5 can be clamped by using the positioning block 602 and the tightening block 601. At this time, if it is necessary to adjust the position of the lens barrel 5, by loosening the bolts between the positioning block 602 and the substrate 2, the positioning block 602 can be rotated along the bolts between it and the substrate 2, thereby driving the lens barrel 5 to move, so that the position of the lens barrel 5 can be adjusted, which is beneficial to ensuring the final imaging quality.

[0025] Please see the attached Figure 2 -Attached Figure 6 The floating flange ring 3 is made of copper. A through hole 201 is defined in the center of the base plate 2, and the floating flange ring 3 is positioned within the through hole 201. The floating flange ring 3 comprises an upper ring 301 and a lower ring 302. The outer wall of the lower ring 302 is provided with a contact surface 1 303, which contacts the inner wall of the through hole 201. The upper and lower rings 301 and 302 have the same inner diameter. The side of the lens barrel 5 closest to the microscope camera 4 is located in the center of the lower ring 302, while the lens of the microscope camera 4 is located in the center of the upper ring 301. The inner diameter of the upper ring 301 is larger than the outer diameter of the lens of the microscope camera 4. The top and bottom surfaces of the upper ring 301 are provided with a second contact surface 304 and a third contact surface 305, respectively. The second contact surface 304 contacts the microscope camera 4, while the third contact surface 305 contacts the top surface of the base plate 2. The fit between the lower ring 302 and the lens barrel 5 is a clearance fit.

[0026] In this embodiment, the floating flange ring 3 is made of copper and is divided into an upper ring 301 and a lower ring 302. The contact surface 1 303 of the lower ring 302 is in close contact with the inner wall of the through hole 201, and the bottom surface (contact surface 3 305) of the upper ring 301 is in contact with the top surface of the substrate 2, thereby preventing the floating flange ring 3 from shifting under gravity or vibration. At the same time, the upper ring 301 and the lower ring 302 have the same inner diameter. The side of the lens barrel 5 closest to the camera is placed in the middle of the lower ring 302, while the lens of the microscope camera 4 is located in the middle of the upper ring 301. Finally, because the inner diameter of the upper ring 301 is larger than the outer diameter of the lens of the microscope camera 4 and there is a clearance fit between the lower ring 302 and the lens barrel 5, the operator can translate the camera within the upper ring 301 so that the center of the lens is aligned with the central axis of the flange ring. The clearance fit allows the entire lens barrel 5 to rotate, so that the lens barrel 5 and the lens remain coaxial. And the top surface (contact surface two 304) of the upper ring 301 contacts the microscope camera 4, and the floating flange ring 3 of copper material has lubricity itself, so as to reduce the friction between it and the microscope camera 4, and then make the microscope camera 4 convenient to move.

[0027] Working principle: when in use, first place the lens barrel 5 on one side of the positioning block 602, then move the lens barrel 5 upwards so that the top of the lens barrel 5 is in the middle of the lower ring 302 of the floating flange ring 3, then install the tightening block 601 on one side of the positioning block 602 by using the bolt, at this time the positioning block 602 and the tightening block 601 will clamp the lens barrel 5, at this time the installation of the lens barrel 5 can be completed; Then the microscope camera 4 can be placed on the floating flange ring 3, at this time the lens of the microscope camera 4 will be in the middle of the upper ring 301 of the floating flange ring 3, then move the microscope camera 4 so that the central axis of the lens of the microscope camera 4 coincides with the central axis of the lens barrel 5; then the imaging operation can be carried out; When it is necessary to replace the lens barrel 5, at this time loosen the bolt between the positioning block 602 and the tightening block 601, at this time the clamping effect of the positioning block 602 and the tightening block 601 on the lens barrel 5 can be cancelled, at this time the lens barrel 5 can be pulled out from between the positioning block 602 and the tightening block 601, then a new lens barrel 5 can be inserted between them, and the bolt between the top block and the tightening block 601 can be tightened again, when it is necessary to replace the microscope camera 4, at this time the microscope camera 4 can be directly taken off from the floating flange ring 3, then a new microscope camera 4 can be placed on the floating flange ring 3.
