Description

Technical Field

[0001] This utility model relates to the field of microscope technology, and in particular to an integrated combined microscope mount and an integrated microscope assembly for laser confocalization. Background Technology

[0002] In the imaging process of laser confocal microscopy, for dynamic processes that need to be captured quickly, such as rapid physiological changes in living cells, high-speed galvanometers are used for rapid line scanning, which can complete the acquisition of a line of images in a short time; while low-speed galvanometers are used for frame scanning. Although the speed is slow, it can ensure that after each line of scanning is completed, there is enough time for positioning and adjustment of the next line, thereby achieving stable acquisition of the entire image.

[0003] Most confocal products only have low-speed scanning capabilities. To simultaneously support both low-speed and high-speed scanning, different hardware and switching devices need to be configured in the instrument. To ensure the size of the image plane, strict requirements need to be placed on the distance from the center of the photosensitive surface of the galvanometer to the scanning lens group. During galvanometer switching, the distance between the high-speed galvanometer and the scanning lens group is very small. How to rationally arrange the scanning lens mount and the galvanometer mount has become an urgent problem to be solved. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide an integrated combination lens mount and an integrated lens assembly for laser confocalization, which has the advantage of facilitating the layout of scanning lenses and high-speed galvanometers.

[0005] The objective of this utility model is achieved through the following technical solution: According to a first aspect of the present disclosure, an integrated combined lens mount is provided, including an integrally formed lens mounting area and a galvanometer mounting area. The lens mounting area is provided with a lens mounting hole adapted to a scanning lens group, and the scanning lens group is inserted and fixed in the lens mounting hole. The galvanometer mounting area is provided with a first galvanometer mounting groove and a second galvanometer mounting groove that are perpendicular to each other in the axial direction. A first high-speed galvanometer is inserted and snapped into the first galvanometer mounting groove, and a second high-speed galvanometer is inserted and snapped into the second galvanometer mounting groove. The first galvanometer mounting groove is disposed on one side close to the lens mounting hole.

[0006] To achieve the above technical solution, the scanning lens group is inserted and fixed in the lens mounting hole, the first high-speed galvanometer is snapped and fixed in the first galvanometer mounting slot, and the second high-speed galvanometer is snapped and fixed in the second galvanometer mounting slot. By setting the first galvanometer mounting slot close to the lens mounting hole, the installation requirements for small pitch can be met, and it is also beneficial to make precise distance adjustments between the first high-speed galvanometer and the second high-speed galvanometer. Furthermore, the one-piece molding method simplifies the subsequent installation process.

[0007] In some exemplary embodiments, the lens mounting hole is provided with a mounting step that matches the lens barrel of the scanning lens assembly, and the rear end of the lens mounting hole is provided with a flange cover for pressing the scanning lens assembly.

The first variable pressure plate is locked to the lens mounting area by a first locking member to clamp and fix the first high-speed galvanometer.

[0010] To achieve the above technical solution, after adjusting the first high-speed galvanometer to a suitable position and angle, tightening the first locking member causes the first variable pressure plate to undergo slight deformation, thereby clamping and fixing the first high-speed galvanometer.

[0011] In some exemplary embodiments, the bottom of the second galvanometer mounting groove is provided with a second deformation groove, the top of the second galvanometer mounting groove is open, and the outer side of the second galvanometer mounting groove is provided with a second variable pressure plate. The second variable pressure plate is locked to the galvanometer mounting area by a second locking member to clamp and fix the second high-speed galvanometer.

[0012] To achieve the above technical solution, after adjusting the second high-speed galvanometer to a suitable position and angle, tighten the second locking component to cause slight deformation of the second variable pressure plate, thereby clamping and fixing the second high-speed galvanometer.

[0013] In some exemplary embodiments, the first variable pressure plate is provided with a first slot for receiving a first locking member, and the second variable pressure plate is provided with a second slot for receiving a second locking member.

[0014] The above technical solution allows the heads of the first locking component and the second locking member to be accommodated respectively through the first slot and the second slot, thereby improving the overall aesthetics after installation.

[0015] In some exemplary embodiments, the horizontal plane containing the axis of the first galvanometer mounting slot is located above the horizontal plane containing the axis of the second galvanometer mounting slot.

[0016] The above technical solution ensures that the first and second high-speed galvanometers will not interfere with each other after installation, facilitating the orderly progress of the installation process.

[0017] In some exemplary embodiments, a transition reinforcement portion is provided between the lens mounting area and the galvanometer mounting area.

[0018] Implementing the above technical solution is beneficial to improving the overall structural strength of the mirror base.

[0019] In some exemplary embodiments, both the lens mounting area and the galvanometer mounting area are provided with connecting lugs on their bottom outer sides, and the connecting lugs are provided with connecting lock holes.

[0020] The above technical solution facilitates the fixing of the microscope mount onto the microscope stage.

[0021] According to a second aspect of the present disclosure, an integrated lens assembly for laser confocalization is provided, comprising: As described in the first aspect, the integrated combination mirror mount; A scanning lens assembly that is inserted and fixed into the lens mounting hole; A first high-speed galvanometer is installed in the first galvanometer mounting slot via a plug-in card. The first high-speed galvanometer can adjust its installation position within the first galvanometer mounting slot. The second high-speed galvanometer is inserted into the second galvanometer mounting slot, and the second high-speed galvanometer can be adjusted in the mounting position within the second galvanometer mounting slot.

[0022] The above technical solution achieves a reasonable layout of the scanning lens group, the first high-speed galvanometer, and the second high-speed galvanometer through the integrated combination lens mount, and effectively simplifies the installation process.

[0023] In some exemplary embodiments, the scanning lens group has a limiting step on its barrel that is adapted to the mounting step.

[0024] To achieve the above technical solution, a limiting step and an installation step are used in combination to enable the positioning and installation of the scanning lens assembly.

[0025] In summary, compared with the prior art, this utility model has the following beneficial effects: This utility model provides an integrated combined lens mount and an integrated lens assembly for laser confocalization.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] like Figures 1 to 5 As shown, the first aspect of this utility model provides an integrated combined lens mount, including an integrally formed lens mounting area 10 and a galvanometer mounting area 20. The lens mounting area 10 is provided with a lens mounting hole 11 adapted to a scanning lens assembly 50. The scanning lens assembly 50 is inserted and fixed in the lens mounting hole 11. The galvanometer mounting area 20 is provided with a first galvanometer mounting groove 21 and a second galvanometer mounting groove 22 that are perpendicular to each other in the axial direction. A first high-speed galvanometer 60 is inserted and snapped into the first galvanometer mounting groove 21, and a second high-speed galvanometer 70 is inserted and snapped into the second galvanometer mounting groove 22. The first galvanometer mounting groove 21 is provided on one side close to the lens mounting hole 11.

[0034] Specifically, the integrated lens mount is formed by casting and then by CNC milling. It can be understood that the lens mounting area 10 and the galvanometer mounting area 20 are just different processing areas of the integrated lens mount, rather than independent components. Furthermore, the lens mounting area 10 and the galvanometer mounting area 20 are also integrally formed with a transition reinforcement 30. This transition reinforcement 30 is in the form of an arc to reduce stress concentration and improve the overall structural strength of the lens mount. At the same time, the bottom outer side of both the lens mounting area 10 and the galvanometer mounting area 20 is provided with a connecting lug 40. The connecting lug 40 is provided with a connecting locking hole 41. The connecting locking hole 41 can be set as a stepped hole. By inserting a bolt into the connecting locking hole 41, it is easy to fix the lens mount to the microscope stage.

[0035] An installation step (not shown in the figure) matching the lens barrel of the scanning lens assembly 50 is provided in the lens mounting hole 11. A flange cover 12 for pressing the scanning lens assembly 50 is provided at the rear end of the lens mounting hole 11. The installation step is an annular step provided in the lens mounting hole 11, or it can be formed by a protrusion provided in the lens mounting hole 11. The scanning lens assembly 50 can be pressed and fixed by the installation step and the flange cover 12. In some embodiments, a threaded hole can also be provided on the flange cover 12 for installing the microscope connection adapter.

[0036] The bottom of the first galvanometer mounting groove 21 is provided with a first deformation groove 23, and the top of the first galvanometer mounting groove 21 is open. The side of the first galvanometer mounting groove 21 opposite to the lens mounting hole 11 is provided with a first variable pressure plate 24. The first variable pressure plate 24 is locked to the lens mounting area 10 by a first locking member to clamp and fix the first high-speed galvanometer 60. It can be understood that the first variable pressure plate 24 has micro-deformation capability. The opening allows the first high-speed galvanometer 60 to be inserted and provides sufficient deformation space for the first variable pressure plate 24. After the first high-speed galvanometer 60 is adjusted to a suitable position and angle, the first locking member is tightened to cause the first variable pressure plate 24 to undergo micro-deformation, thereby clamping and fixing the first high-speed galvanometer 60.

[0037] The bottom of the second galvanometer mounting slot 22 is provided with a second deformation slot 26, the top of the second galvanometer mounting slot 22 is open, and the outer side of the second galvanometer mounting slot 22 is provided with a second variable pressure plate 27. The second variable pressure plate 27 is locked to the galvanometer mounting area 20 by a second locking member to clamp and fix the second high-speed galvanometer 70. Similarly, the second variable pressure plate 27 has micro-deformation capability. The opening allows the first high-speed galvanometer 60 to be inserted and provides sufficient deformation space for the first variable pressure plate 24. After the second high-speed galvanometer 70 is adjusted to a suitable position and angle, the second locking member is tightened to cause the second variable pressure plate 27 to undergo micro-deformation, thereby clamping and fixing the second high-speed galvanometer 70.

[0038] Meanwhile, the first variable pressure plate 24 is provided with a first slot 25 for accommodating the first locking member, and the second variable pressure plate 27 is provided with a second slot 28 for accommodating the second locking member. Both the first slot 25 and the second slot 28 have through connecting holes to allow the first locking member and the second locking member to be inserted. Both the first locking member and the second locking member are made of round-headed hexagonal socket head cap screws. The first slot 25 and the second slot 28 can respectively accommodate the heads of the first locking member and the second locking member to improve the overall aesthetics after installation.

[0039] The horizontal plane containing the axis of the first galvanometer mounting slot 21 is located above the horizontal plane containing the axis of the second galvanometer mounting slot 22. That is, in space, the first galvanometer mounting slot 21 and the second galvanometer mounting slot 22 are arranged vertically offset, so that the first high-speed galvanometer 60 and the second high-speed galvanometer 70 will not interfere after installation, which facilitates the orderly progress of the installation process.

[0040] The scanning lens group 50 is inserted and fixed to the lens mounting hole 11, the first high-speed galvanometer 60 is snapped and fixed to the first galvanometer mounting slot 21, and the second high-speed galvanometer 70 is snapped and fixed to the second galvanometer mounting slot 22. By setting the first galvanometer mounting slot 21 close to the lens mounting hole 11, the installation requirements for small pitch can be met, and it is also beneficial to make precise distance adjustments between the first high-speed galvanometer 60 and the second high-speed galvanometer. Moreover, the one-piece molding method can simplify the subsequent installation process.

[0041] A second aspect of this utility model provides an integrated lens assembly for laser confocalization, comprising: an integral combined lens mount as described in the first aspect; a scanning lens assembly 50 inserted and fixed to a lens mounting hole 11; a first high-speed galvanometer 60 inserted and snapped into a first galvanometer mounting slot 21, the first high-speed galvanometer 60 being adjustable in position within the first galvanometer mounting slot 21; and a second high-speed galvanometer 70 inserted and snapped into a second galvanometer mounting slot 22, the second high-speed galvanometer 70 being adjustable in position within the second galvanometer mounting slot 22.

[0042] Specifically, such as Figure 5 As shown, the scanning lens group 50 has a limiting step 51 on its barrel that matches the mounting step. The limiting step 51 and the mounting step work together to achieve the positioning and installation of the scanning lens group 50. Due to space requirements, the barrel wall of the scanning lens group 50 is very thin. Adding the limiting step can also enhance the strength of the barrel. The thin wall also ensures that the scanning lens group 50 and the second high-speed galvanometer 70 are as close as possible. The first high-speed galvanometer 60 is a resonant galvanometer, and the second high-speed galvanometer 70 is a Galvano galvanometer. The integrated combination mount can achieve a reasonable layout of the scanning lens group 50, the first high-speed galvanometer 60 and the second high-speed galvanometer 70, and can effectively simplify the installation process.

[0043] The installation process of this utility model is as follows: First, insert the second high-speed galvanometer 70 into the second galvanometer mounting slot 22 and adjust it to the predetermined installation position and angle. Then, tighten the second locking member to cause the second variable pressure plate 27 to undergo slight deformation, thereby clamping and fixing the second high-speed galvanometer 70. Next, insert the scanning lens group 50 into the lens mounting hole 11 and then tighten the flange cover 12 to press and fix the scanning lens group 50. Finally, insert the first high-speed galvanometer 60 into the first galvanometer mounting slot 21 and adjust it to the predetermined installation position and angle. Tighten the first locking member to cause the first variable pressure plate 24 to undergo slight deformation, thereby clamping and fixing the first high-speed galvanometer 60. The entire installation process is then completed.

[0044] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
