[0001] The present disclosure belongs to the field of optical imaging technology, and particularly relates to a microscope and an adjustment method thereof. Background Art

[0002] In the field of imaging technology, microscopes and cameras, for example, have at least two lenses. Light sequentially passes through different lenses to form an image, and ensuring that the optical axes of these lenses coincide with each other is crucial for clear imaging. However, microscope lenses are typically fixed in position and cannot be adjusted as needed, making it difficult to achieve accurate alignment of the optical axes of the lenses, resulting in poor imaging quality.

[0005] In a second aspect, an embodiment of the present disclosure also provides a microscope adjustment method, which is applied to the above-mentioned microscope, and the adjustment method includes: installing a first aperture at the bottom of the objective lens and placing a reflector below the objective lens; setting a laser emitting device above the objective lens and setting a second aperture between the laser emitting device and the objective lens; adjusting the position of the laser emitting device so that the laser emitted by the laser emitting device passes through the objective lens and is reflected by the reflector and then passes through the first aperture and the second aperture in sequence; installing an adjustment mechanism and a magnification lens on the support seat, and using the adjustment mechanism to adjust the position of the magnification lens so that the laser passes through the magnification lens and the objective lens in sequence and passes through the first aperture and the second aperture in sequence after being reflected by the reflector.

[0006] In the disclosed embodiment, the microscope is additionally provided with an adjustment mechanism, and the position of the magnification lens is adjusted by the adjustment mechanism. Specifically, the movement position of the magnification lens in the X direction and the rotation position in the direction around the first axis are adjusted by the first adjustment component.

DETAILED DESCRIPTION

[0018] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present disclosure.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present disclosure can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects related to each other are in an "or" relationship.

[0020] The microscope and the adjustment method thereof provided by the embodiments of the present disclosure are described in detail below with reference to specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0021] Please refer to Figures 1 to 9. The microscope disclosed in the embodiment of the present disclosure includes a support base 100, an objective lens 210, a magnification lens 220 and an adjustment mechanism 300, wherein the support base 100 serves as an installation component for the objective lens 210, the magnification lens 220 and the adjustment mechanism 300, the objective lens 210 is arranged on the support base 100, the objective lens 210 is fixedly connected to the support base 100, and the magnification lens 220 is movably connected to the support base 100 through the adjustment mechanism 300, that is, the magnification lens 220 is installed on the support base 100 through the adjustment mechanism 300.

[0022] Optionally, as shown in FIG1 , the bottom of the support base 100 has a support surface, on which a plane mirror, a glass slide, etc. can be placed. The microscope further comprises an adapter plate 600, which is mounted on the top of the support base 100. The objective lens 210 is mounted on the bottom of the adapter plate 600 so that the objective lens 210 is opposite to the support surface. The adjustment mechanism 300 is mounted on the side of the adapter plate 600. The magnification lens 220 is further mounted on the adjustment mechanism 300 so that the magnification lens 220 is located above the objective lens 210. The adapter plate 600 and the support base 100, as well as the objective lens 210 and the adapter plate 600, can be fixedly connected by welding, bonding, or the like.

[0023] The adjustment mechanism 300 includes a first adjustment assembly 310 and a second adjustment assembly 320 connected to each other. The second adjustment assembly 320 is connected to the variator 220. Therefore, the second adjustment assembly 320 can directly adjust the position of the variator 220, while the first adjustment assembly 310 needs to indirectly adjust the position of the variator 220 by adjusting the position of the second adjustment assembly 320. The first adjustment assembly 310 can adjust the second adjustment assembly 320 to drive the variator 220 to move in the X direction and rotate about the first axis α. The second adjustment assembly 320 can also adjust the variator 220 to move in the Y direction and rotate about the second axis β to adjust the optical axis position of the variator 220, thereby aligning the optical axis of the variator 220 with the optical axis of the objective lens 210.

[0024] The X direction and the Y direction intersect with the optical axis of the objective lens 210 respectively, and the first axis α and the second axis β intersect with the optical axis of the objective lens 210 respectively.

[0025] Optionally, the first adjustment assembly 310 may include a first movable driver and a first rotary driver. The output shaft of the first rotary driver is connected to the second adjustment assembly 320 to drive the second adjustment assembly 320 to rotate the zoom lens 220 about the first axis α. The first movable driver is connected to the first rotary driver to drive the first rotary driver, the second adjustment assembly 320, and the zoom lens 220 to move along the X direction. The first movable driver may be a component that generates a linear driving force, such as a pneumatic cylinder, an electric cylinder, or a movable module; the first rotary driver may be a component that generates a rotational force, such as an electric motor or a pneumatic motor.

[0026] Optionally, the second adjustment assembly 320 may include a second movable driver and a second rotary driver. The output shaft of the second rotary driver is connected to the zoom lens 220 to drive the zoom lens 220 to rotate about the second axis β. The second movable driver is connected to the second rotary driver to drive the second rotary driver and the zoom lens 220 to move along the Y direction. The second movable driver may be a component that generates a linear driving force, such as a pneumatic cylinder, an electric cylinder, or a movable module. The second rotary driver may be a component that generates a rotational force, such as an electric motor or a pneumatic motor.

[0027] In the embodiment of the present disclosure, the microscope is additionally provided with an adjustment mechanism 300, and the position of the magnification lens 220 is adjusted by the adjustment mechanism 300. For example, the movement position of the magnification lens 220 in the X direction and the rotation position around the first axis α are adjusted by the first adjustment component 310. At the same time, the movement position of the magnification lens 220 in the Y direction and the rotation position around the second axis β are adjusted by the second adjustment component 320, so that the optical axis of the objective lens 210 and the optical axis of the magnification lens are collinear, that is, the optical axes of the two are accurately coincident, which is conducive to accurate imaging of the microscope and improves the imaging effect.

[0028] In an optional embodiment, the X direction may be perpendicular to the Y direction, and both are perpendicular to the optical axis of the objective lens 210, that is, the X direction and the Y direction are respectively parallel to the support surface of the support base 100; the first axis α is perpendicular to the second axis β, and both are respectively perpendicular to the optical axis of the objective lens 210. With this embodiment, by adjusting the movement position of the magnification lens 220 in the X direction and the Y direction, it is convenient to quickly and accurately adjust the position of the magnification lens 220 in a plane perpendicular to the optical axis of the objective lens 210, so that the objective lens 210 and the magnification lens 220 are accurately relative to each other; at the same time, by adjusting the position of the magnification lens 220 in the direction around the first axis α and in the direction around the second axis β, it is convenient to quickly and accurately adjust the rotation position of the magnification lens 220, so that the optical axis of the objective lens 210 and the optical axis of the magnification lens 220 are collinear.

[0029] Optionally, the direction of the first axis α is parallel to the Y direction, the direction of the second axis β is parallel to the X direction, the Y direction is the direction of the Y axis, the X direction is the direction of the X axis, the direction of rotation about the first axis α is the direction of rotation about the Y axis, and the direction of rotation about the second axis β is the direction of rotation about the X axis. In this way, the microscope can achieve four motion processes: movement in the X direction, movement in the Y direction, rotation about the Y axis, and rotation about the X axis, thereby achieving adjustment of four degrees of freedom.

[0030] Further optionally, as shown in FIG1 , the X-direction and the Y-direction are perpendicular to the height direction of the microscope, and the X-direction and the Y-direction can be the length and width directions of the microscope, respectively. In this manner, the first adjustment assembly 310 can adjust the second adjustment assembly 320 and the zoom lens 220 for movement in the X-direction, and the second adjustment assembly 320 can adjust the zoom lens 220 for movement in the Y-direction, thereby adjusting the horizontal position of the zoom lens 220. The first adjustment assembly 310 can adjust the second adjustment assembly 320 and the zoom lens 220 for rotation about the Y-axis, and the second adjustment assembly 320 can adjust the zoom lens 220 for rotation about the X-axis, thereby fully adjusting the rotational position of the zoom lens 220, which is more conducive to accurate adjustment and achieves collinearity between the optical axes of the objective lens 210 and the zoom lens 220. Of course, the direction of the first axis α can intersect with but not be parallel to the Y-direction, and the direction of the second axis β can intersect with but not be parallel to the X-direction.

[0031] Of course, in other embodiments, the X direction may intersect with the Y direction but not be perpendicular thereto, and the first axis α may intersect with the second axis β but not be perpendicular thereto.

[0032] In an optional embodiment, as shown in Figures 2 and 3, the first adjustment component 310 includes a dual-axis fixed plate 311 and a movable plate 312. The dual-axis fixed plate 311 is connected to the support base 100. Optionally, the dual-axis fixed plate 311 is indirectly connected to the support base 100 through an adapter plate 600. The dual-axis fixed plate 311 and the adapter plate 600 can be fixedly connected by welding, bonding, etc.; the movable plate 312 is connected to the second adjustment component 320. The movable plate 312 can drive the second adjustment component 320 and the magnification lens 220 to move along the X direction relative to the dual-axis fixed plate 311 and rotate around the first axis α.

[0033] One of the dual-axis fixed plate 311 and the movable plate 312 is provided with a first strip hole 3121, and the other is provided with a first cylindrical protrusion 3111. The first strip hole 3121 extends along the X direction, and the first axis α is collinear with the axis of the first cylindrical protrusion 3111. The first cylindrical protrusion 3111 extends into the first strip hole 3121. The first cylindrical protrusion 3111 can move along the extension direction of the first strip hole 3121, and the first cylindrical protrusion 3111 can move and rotate relative to the first strip hole 3121. Optionally, the biaxial fixed plate 311 is provided with a first strip hole 3121, and the movable plate 312 is provided with a first cylindrical protrusion 3111; or, the biaxial fixed plate 311 is provided with a first cylindrical protrusion 3111, and the movable plate 312 is provided with a first strip hole 3121. Further optionally, the first cylindrical protrusion 3111 can be formed by a cylindrical pin installed on the biaxial fixed plate 311. Of course, the first cylindrical protrusion 3111 can also be formed by other structures welded to the biaxial fixed plate 311.

[0034] This embodiment, by providing first strip-shaped holes 3121 and first cylindrical protrusions 3111 on the dual-axis fixed plate 311 and movable plate 312, respectively, provides both movement support and rotational support for movable plate 312, thereby enhancing stability during movement and rotation. Furthermore, the movement and rotational forces can be applied directly to movable plate 312, eliminating the need to drive other drive components during movement or rotation, making adjustment more labor-efficient.

[0035] In a further embodiment, the movable plate 312 is movably connected to the dual-axis fixed plate 311, and the adjustment mechanism 300 further includes a first elastic member 318, wherein a first end of the first elastic member 318 is connected to the movable plate 312, and a second end of the first elastic member 318 is connected to the dual-axis fixed plate 311. Optionally, the first elastic member 318 may be, but is not limited to, a spring. The adjustment mechanism 300 further includes at least two first support shafts 3181, wherein a first end of the first elastic member 318 is fixed to the movable plate 312 via one of the first support shafts 3181, and a second end of the first elastic member 318 is fixed to the dual-axis fixed plate 311 via the other first support shaft 3181.

[0036] With this arrangement, the first elastic member 318 is used to realize the movable connection between the movable plate 312 and the biaxial fixed plate 311, which can not only enable the movable plate 312 to rotate and move relative to the biaxial fixed plate 311, but also prevent the movable plate 312 from being completely separated from the biaxial fixed plate 311, thereby ensuring the stability of the connection.

[0037] Of course, in other embodiments, the first elastic member 318 may not be provided between the movable plate 312 and the dual-axis fixed plate 311 , and the two are movably connected only through the first strip hole 3121 and the first cylindrical protrusion 3111 .

[0038] In an optional embodiment, with reference to Figures 2 and 3, the first adjustment assembly 310 further includes a first connecting block 313, a second connecting block 314 and a first adjusting screw 315, wherein the first connecting block 313 is arranged on the biaxial fixed plate 311, and the second connecting block 314 is arranged on the movable plate 312. Optionally, the first connecting block 313 and the biaxial fixed plate 311, the second connecting block 314 and the movable plate 312 can be fixedly connected by welding, bonding, etc.; one of the first connecting block 313 and the second connecting block 314 is provided with a first through hole 3131, and the other is provided with a first threaded hole 3141, which is provided on the first of the second connecting block 314. The axis of the through hole 3131 or the first threaded hole 3141 is parallel to the X direction. The first adjusting screw 315 can be a component with external threads such as a screw, a bolt, or a stud. The first adjusting screw 315 passes through the first through hole 3131 and extends into the first threaded hole 3141. By screwing the first adjusting screw 315, the movable plate 312 can be moved relative to the biaxial fixed plate 311 along the X direction. Optionally, the first connecting block 313 is provided with a first through hole 3131, and the second connecting block 314 is provided with a first threaded hole 3141, or the first connecting block 313 is provided with a first threaded hole 3141, and the second connecting block 314 is provided with a first through hole 3131.

[0039] It should be noted that the diameter of the first through hole 3131 is larger than that of the first threaded hole 3141, that is, there is a gap between the wall surface of the first through hole 3131 and the first adjusting screw 315. As a result, when the movable plate 312 rotates a certain amount relative to the dual-axis fixed plate 311 about the first axis α, the first adjusting screw 315 can also move with the movable plate 312 relative to the first through hole 3131, thus avoiding the problem of the first adjusting screw 315 being unable to rotate and adjust.

[0040] With this embodiment, the first adjusting screw 315 is manually screwed as needed to adjust the movement position of the second connecting block 314 relative to the first connecting block 313 in the X direction, thereby adjusting the position of the movable plate 312 relative to the dual-axis fixed plate 311 in the X direction. This eliminates the need for additional complex moving drive components such as pneumatic cylinders, electric cylinders, and linear modules, thereby simplifying the structure and saving energy.

[0041] In an optional embodiment, as shown in FIG2 , the first adjustment assembly 310 further includes a first connecting block 313, a second connecting block 314, and a second adjusting screw 316. The first connecting block 313 is disposed on the dual-axis fixed plate 311, and the second connecting block 314 is disposed on the movable plate 312. One of the first connecting block 313 and the second connecting block 314 is provided with a second threaded hole 3132. The second adjusting screw 316 passes through the second threaded hole 3132 and abuts against the other of the first connecting block 313 and the second connecting block 314. By turning the second adjusting screw 316, the movable plate 312 can be moved relative to the dual-axis fixed plate 311 in the X-direction. Optionally, the second threaded hole 3132 is disposed on the first connecting block 313, with the axis of the second threaded hole 3132 parallel to the X-direction. The second adjusting screw 316 can be a component having external threads, such as a screw, bolt, or stud.

[0042] With this embodiment, the second adjusting screw 316 is manually screwed as needed to adjust the movement position of the second connecting block 314 in the X direction relative to the first connecting block 313, thereby adjusting the position of the movable plate 312 in the X direction relative to the dual-axis fixed plate 311. This eliminates the need for additional complex moving drive components such as pneumatic cylinders, electric cylinders, and linear modules, thereby simplifying the structure and saving energy.

[0043] In this embodiment, the first adjustment assembly 310 includes a first adjustment screw 315 and a second adjustment screw 316. The first through hole 3131 and the second threaded hole 3132 are both provided in the first connecting block 313. The first adjustment screw 315 and the second adjustment screw 316 are both located on the same side of the movable plate 312 and are arranged side by side. Thus, by tightening the first adjustment screw 315, the second connecting block 314 can be gradually moved closer to the first connecting block 313 in the +X direction. Alternatively, by tightening the second adjustment screw 316 against the first connecting block 313 or the second connecting block 314, the second connecting block 314 can be gradually moved away from the first connecting block 313 in the -X direction. Therefore, the first adjustment screw 315 and the second adjustment screw 316 respectively adjust the movable plate 312 in two opposite directions in the X direction. The +X direction and the -X direction are two opposite directions in the X direction.

[0044] It should be noted that when screwing the first adjusting screw 315, the second adjusting screw 316 needs to be loosened in advance; similarly, when screwing the second adjusting screw 316, the first adjusting screw 315 needs to be loosened in advance and disengaged from the first threaded hole 3141 to avoid mutual interference between the first adjusting screw 315 and the second adjusting screw 316.

[0045] In an optional embodiment, the first adjustment assembly 310 further includes a first connecting block 313, a second connecting block 314, a third adjusting screw 3171, and a fourth adjusting screw 3172. The first connecting block 313 is disposed on the dual-axis fixed plate 311, and the second connecting block 314 is disposed on the movable plate 312. One of the first connecting block 313 and the second connecting block 314 is defined by a first groove 3133, and the other extends into the first groove 3133. That is, the first connecting block 313 is defined by the first groove 3133, and the second connecting block 314 extends into the first groove 3133, or the second connecting block 314 is defined by the first groove 3133, and the first connecting block 313 extends into the first groove 3133. Optionally, the third adjusting screw 3171 and the fourth adjusting screw 3172 may be components having external threads, such as screws, bolts, and studs.

[0046] As shown in Reference Figure 2, in the Z direction, the two opposite side walls of the first groove 3133 are respectively provided with a third threaded hole and a fourth threaded hole, and the X direction and the Y direction both intersect with the Z direction. Optionally, the Z direction can be perpendicular to the X direction and the Y direction respectively, and the Z direction can be the height direction of the microscope; the third adjusting screw 3171 passes through the third threaded hole and abuts against the other one, and the fourth adjusting screw 3172 passes through the fourth threaded hole and abuts against the other one, that is, the third adjusting screw 3171 and the fourth adjusting screw 3172 simultaneously abut against the opposite sides of the first connecting block 313 or the second connecting block 314, and by screwing the third adjusting screw 3171 and the fourth adjusting screw 3172, the movable plate 312 can be rotated around the first axis α relative to the dual-axis fixed plate 311.

[0047] In the process of tightening the third adjusting screw 3171 and loosening the fourth adjusting screw 3172, the first connecting block 313 or the second connecting block 314 swings around the first cylindrical protrusion 3111, that is, gradually approaches the fourth adjusting screw 3172 around the first axis α; conversely, in the process of tightening the fourth adjusting screw 3172 and loosening the third adjusting screw 3171, the first connecting block 313 or the second connecting block 314 swings around the first cylindrical protrusion 3111, that is, gradually approaches the third adjusting screw 3171 around the first axis α.

[0048] By adopting this embodiment, the third adjusting screw 3171 and the fourth adjusting screw 3172 can be manually screwed as needed to adjust the second connecting block 314 to rotate relative to the first connecting block 313 around the first axis α, and then adjust the rotation position of the movable plate 312 around the first axis α relative to the dual-axis fixed plate 311. There is no need to additionally set up complex rotating drive components such as motors, which is conducive to simplifying the structure and saving energy.

[0049] Optionally, the first connecting block 313 is provided with a first groove 3133 , the first through hole 3131 and the second threaded hole 3132 are both arranged on the bottom wall of the first groove 3133 , and the third threaded hole and the fourth threaded hole are respectively arranged on the top and bottom side walls of the first groove 3133 .

[0050] It should be noted that before adjusting the third and fourth adjusting screws 3171 and 3172, the first adjusting screw 315 must be loosened and disengaged from the first threaded hole 3141, and the second adjusting screw 316 must be loosened. Similarly, before adjusting the first and second adjusting screws 315 and 316, the third and fourth adjusting screws 3171 and 3172 must be loosened to prevent the abutting force of the third and fourth adjusting screws 3171 and 3172 from preventing movement and adjustment. The first, second, third, and fourth adjusting screws are then slowly adjusted simultaneously to achieve the desired position and orientation. This prevents the individual adjusting screws from interfering with each other, ensuring smooth rotation and movement adjustment.

[0051] In the solution of the present disclosure, with reference to Figure 4, the second adjustment assembly 320 includes a movable plate 321, a third connecting block 322, a fourth connecting block 323, a fifth adjusting screw 3241 and a sixth adjusting screw 3242. The movable plate 321 is slidably connected to the movable plate 312 along the Y direction. The third connecting block 322 is arranged on the movable plate 312, and the fourth connecting block 323 is arranged on the movable plate 321. Optionally, the third connecting block 322 and the movable plate 312, and the fourth connecting block 323 and the movable plate 321 can be fixedly connected by welding, bonding, etc.; one of the third connecting block 322 and the fourth connecting block 323 is provided with a second groove 3221, and the other extends into the second groove 3221, that is, the third connecting block 322 is provided with the second groove 3221, and the fourth connecting block 323 extends into the second groove 3221, or the fourth connecting block 323 is provided with the second groove 3221, and the third connecting block 322 extends into the second groove 3221.

[0052] The fifth adjusting screw member 3241 and the sixth adjusting screw member 3242 may be components with external threads, such as screws, bolts, and studs.

[0053] In the Y direction, the opposite side walls of the second groove 3221 are respectively provided with a fifth threaded hole 3222 and a sixth threaded hole 3223, the fifth adjusting screw 3241 passes through the fifth threaded hole 3222 and presses against the other one, and the sixth adjusting screw 3242 passes through the sixth threaded hole 3223 and presses against the other one, that is, the fifth adjusting screw 3241 and the sixth adjusting screw 3242 simultaneously press against the third connecting block 322 or the fourth connecting block 323 on opposite sides along the Y direction, and the movable plate 321 can be moved relative to the movable plate 312 along the Y direction by screwing the fifth adjusting screw 3241 and the sixth adjusting screw 3242.

[0054] In the process of tightening the fifth adjusting screw 3241 and loosening the sixth adjusting screw 3242, the third connecting block 322 or the fourth connecting block 323 gradually approaches the sixth adjusting screw 3242 along the Y direction; conversely, in the process of tightening the sixth adjusting screw 3242 and loosening the fifth adjusting screw 3241, the third connecting block 322 or the fourth connecting block 323 gradually approaches the fifth adjusting screw 3241 along the Y direction.

[0055] By adopting this embodiment, the fifth adjusting screw 3241 and the sixth adjusting screw 3242 can be manually screwed as needed to adjust the relative movement of the third connecting block 322 and the fourth connecting block 323 in the Y direction, and then the relative movement of the movable plate 312 and the movable plate 321 in the Y direction can be adjusted. There is no need to additionally set up complex moving drive parts such as cylinders, electric cylinders, and linear modules, which is conducive to simplifying the structure and saving energy.

[0056] In a further embodiment, as shown in Figures 4 and 5 , the movable plate 321 is slidably connected to the movable plate 312 in the Y direction, and the adjustment mechanism 300 further includes a second elastic member 328, wherein a first end of the second elastic member 328 is connected to the movable plate 321, and a second end of the second elastic member 328 is connected to the movable plate 312. Optionally, the second elastic member 328 may be, but is not limited to, a spring, and the adjustment mechanism 300 may further include at least two second support shafts 3281, wherein a first end of the second elastic member 328 is fixed to the movable plate 321 via one of the second support shafts 3281, and a second end of the second elastic member 328 is fixed to the movable plate 312 via the other second support shaft 3281.

[0057] With this arrangement, the second elastic member 328 is used to realize the movable connection between the movable plate 312 and the movable plate 321 , which can not only enable the movable plate 312 to move relative to the movable plate 321 , but also prevent the movable plate 312 from being completely separated from the movable plate 321 , thereby ensuring the connection stability.

[0058] In an alternative embodiment, as shown in Figures 4 and 5 , one of the movable plate 312 and the moving plate 321 is provided with a first opening 3122, and the other is provided with a second strip-shaped hole 3211, wherein the second strip-shaped hole 3211 extends along the Y-direction. The second adjustment assembly 320 further includes a first ball 3251, a portion of which extends into the first opening 3122. The first opening 3122 is used to position the first ball 3251, thereby fixing the first ball 3251 relative to the movable plate 312 or the moving plate 321 having the first opening 3122. Furthermore, another portion of the first ball 3251 extends into the second strip-shaped hole 3211, and the first ball 3251 is movable relative to the second strip-shaped hole 3211 along the direction in which the second strip-shaped hole 3211 extends. In other words, the first ball 3251 moves along the Y-direction relative to the moving plate 321 or the movable plate 312 having the second strip-shaped hole 3211.

[0059] As shown in FIG. 4 , the movable plate 312 may be provided with a first opening 3122 , and as shown in FIG. 5 , the movable plate 321 may be provided with a second strip hole 3211 ; or, the movable plate 312 may be provided with a second strip hole 3211 and the movable plate 321 may be provided with a first opening 3122 .

[0060] Optionally, the first opening 3122 can be a cylindrical hole. Further optionally, the first opening 3122 can be a cylindrical hole, a square cylindrical hole or the like. The embodiment of the present disclosure does not limit the structure of the first opening 3122. The first opening 3122 can only allow a portion of the first ball 3251 to extend into.

[0061] In this embodiment, the structure of the first opening 3122, the second strip-shaped hole 3211, and the first ball bearing 3251 guides the movement direction of the movable plate 321 relative to the movable plate 312, facilitating accurate movement of the movable plate 321 in the Y direction relative to the movable plate 312. Furthermore, the first ball bearing 3251 converts the sliding friction between the movable plate 321 and the movable plate 312 into rolling friction, reducing the friction during movement of the movable plate 321 in the Y direction relative to the movable plate 312 and making adjustment more labor-efficient.

[0062] Of course, in other embodiments, the second elastic member 328 and the first ball 3251 may not be provided between the movable plate 312 and the moving plate 321 , and the two may be directly slidably connected via matching slide rails and sliders.

[0063] In an optional embodiment, referring to Figures 2 and 7, it can be seen that the movable plate 312 and the movable plate 321 each include a first side portion 301 and a second side portion 302 opposite to each other, and a connecting portion 303, and the first side portion 301 is connected to the second side portion 302 via the connecting portion 303; as shown in Figure 4, the first side portion 301 and the second side portion 302 of the movable plate 312 are both provided with a first opening 3122, and as shown in Figure 5, the first side portion 301 and the second side portion 302 of the movable plate 321 are both provided with a second strip-shaped hole 3211, the number of the first rolling balls 3251 is at least two, and the first rolling balls 3251, the first opening 3122 and the second strip-shaped hole 3211 correspond to each other one by one. Optionally, the first side portion 301 and the second side portion 302 of the movable plate 312 are both provided with at least two first openings 3122, and the first side portion 301 and the second side portion 302 of the movable plate 321 are both provided with at least two second strip-shaped holes 3211.

[0064] With this arrangement, multiple first balls 3251 are used to roll along the Y direction to guide multiple positions of the movable plate 321, which is more conducive to the accurate movement of the movable plate 321 along the Y direction relative to the movable plate 312. Moreover, the friction force is further reduced, which is more conducive to the smooth movement of the movable plate 321.

[0065] In a further embodiment, the second strip-shaped hole 3211 provided in the first side portion 301 is provided with a first limiting structure, which cooperates with the first ball 3251 to limit the position in the X direction. Alternatively, the first limiting structure can be a limiting protrusion provided on the wall surface of the second strip-shaped hole 3211, and both of the two opposing wall surfaces of the second strip-shaped hole 3211 in the X direction can be provided with limiting protrusions. Further optionally, as shown in FIG5 , the limiting protrusion can be a wedge-shaped protrusion, which contacts the first ball 3251 in the X direction. Of course, the first limiting structure can also be other limiting structures.

[0066] In this configuration, the first limiting structure is used to limit the position of the first ball 3251 in the X direction, thereby preventing the first ball 3251 from being displaced in the X direction, and facilitating accurate movement of the first ball 3251 in the Y direction.

[0067] Of course, in other embodiments, the second bar-shaped hole 3211 disposed on the first side portion 301 may not be provided with the first limiting structure.

[0068] In an optional embodiment, the width of the first strip hole 3121 set on the first side portion 301 and the second strip hole 3211 set on the second side portion 302 are both equal to or smaller than the diameter of the first ball 3251, preventing the first ball 3251 from moving along the X direction relative to the corresponding second strip hole 3211.

[0069] In another embodiment, the width of the second strip-shaped hole 3211 provided on the first side portion 301 is less than or equal to the diameter of the first ball 3251, and the width of the second strip-shaped hole 3211 provided on the second side portion 302 is greater than the diameter of the first ball 3251. In other words, there is a gap between the sidewall of the second strip-shaped hole 3211 provided on the second side portion 302 and the corresponding first ball 3251. With this arrangement, after the first ball 3251 is accurately installed in the second strip-shaped hole 3211 provided on the first side portion 301, to avoid machining errors that may cause the corresponding first ball 3251 to be incorrectly installed in the second side portion 302, the width of the second strip-shaped hole 3211 provided on the second side portion 302 is increased to ensure that the first ball 3251 can smoothly enter the second strip-shaped hole 3211 provided on the second side portion 302.

[0070] In an optional embodiment, as shown in Figures 6 and 7, the second adjustment assembly 320 also includes a pitch seat 326 and a seventh adjustment screw 327. The pitch seat 326 is connected to the magnification lens 220. Optionally, the pitch seat 326 and the magnification lens 220 can be fixedly connected by welding, bonding, etc.; the pitch seat 326 is rotatably connected to the movable plate 321 around the second axis β, one of the pitch seat 326 and the movable plate 321 is provided with a second through hole 3261, and the other is provided with a seventh threaded hole 3212, the seventh adjustment screw 327 passes through the second through hole 3261 and extends into the seventh threaded hole 3212, the seventh threaded hole 3212 and the second through hole 3261 are both deviated from the second axis β, and the pitch seat 326 can be rotated around the second axis β relative to the movable plate 321 by screwing the seventh adjustment screw 327. Specifically, the pitch seat 326 is provided with a second through hole 3261 , and the movable plate 321 is provided with a seventh threaded hole 3212 ; or, the pitch seat 326 is provided with a seventh threaded hole 3212 , and the movable plate 321 is provided with a second through hole 3261 .

[0071] The seventh adjusting threaded member 327 may be a component with external threads, such as a screw, a bolt, or a stud.

[0072] It should be noted that the second through hole 3261 has a relatively large diameter, and there is a gap between the wall of the second through hole 3261 and the seventh adjustment screw 327. As a result, when the seventh adjustment screw 327 is tightened, the nut of the seventh adjustment screw 327 abuts against the pitch seat 326. Furthermore, the seventh adjustment screw 327 has a certain amount of movement relative to the pitch seat 326, ensuring smooth rotation of the pitch seat 326 and avoiding the problem of the seventh adjustment screw 327 being unable to rotate and adjust the pitch seat 326.

[0073] By adopting this embodiment, the pitch seat 326 can be rotated around the second axis β relative to the movable plate 321 by manually screwing the seventh adjusting screw 327 as needed, without the need to set up additional complex rotating drive components such as motors and pneumatic motors, which is conducive to simplifying the structure and saving energy.

[0074] In an optional embodiment, one of the pitch seat 326 and the movable plate 321 is provided with a cylindrical groove, and the other is provided with a second cylindrical protrusion, the axis of the second cylindrical protrusion is the second axis β, the second cylindrical protrusion extends into the cylindrical groove, and the second cylindrical protrusion rotates with the cylindrical groove, thereby realizing the rotational connection between the pitch seat 326 and the movable plate 321.

[0075] In another embodiment, the second adjustment assembly 320 further includes a second ball bearing 3252. One of the movable plate 321 and the tilt seat 326 is provided with a second opening 3213, and the other is provided with a receiving slot 3262. The second opening 3213 and the receiving slot 3262 are opposite each other. Both the second opening 3213 and the receiving slot 3262 position the second ball bearing 3252. A portion of the second ball bearing 3252 extends into the second opening 3213, and another portion of the second ball bearing 3252 extends into the receiving slot 3262. Specifically, the movable plate 321 is provided with the second opening 3213, and the tilt seat 326 is provided with the receiving slot 3262; alternatively, the movable plate 321 is provided with the receiving slot 3262, and the tilt seat 326 is provided with the second opening 3213.

[0076] Optionally, the second opening 3213 can be a cylindrical hole. Further optionally, the second opening 3213 can be a cylindrical hole, a square cylindrical hole or the like. The embodiment of the present disclosure does not limit the structure of the second opening 3213. The second opening 3213 can only allow a portion of the second ball 3252 to extend into.

[0077] 6 and 7, there are at least two pitch seats 326, including a first pitch seat 326A and a second pitch seat 326B that are opposite to each other. The zoom lens 220 is connected to the first pitch seat 326A and the second pitch seat 326B at the same time. The first pitch seat 326A and the second pitch seat 326B are both provided with a receiving groove 3262 or a second opening 3213. The number of the second ball bearings 3252 and the second opening 3213 are both at least two. The second ball bearings 3252, the second opening 3213 and the receiving groove 3262 are respectively paired with each other. The straight line formed by the axis center of the second ball 3252 corresponding to the first pitch seat 326A and the axis center of the second ball 3252 corresponding to the second pitch seat 326B is the second axis β. Optionally, when the first pitch seat 326A and the second pitch seat 326B have a receiving groove 3262, the straight line formed by the axis center of the second ball 3252 corresponding to the receiving groove 3262 opened in the first pitch seat 326A and the axis center of the second ball 3252 corresponding to the receiving groove 3262 opened in the second pitch seat 326B is the second axis β.

[0078] Optionally, the first pitch seat 326A is rotatably connected to the first side portion 301 of the movable plate 321, and the second pitch seat 326B is rotatably connected to the second side portion 302 of the movable plate 321. The first pitch seat 326A and the second pitch seat 326B are both provided with a seventh threaded hole 3212 or a second through hole 3261. There are at least two seventh adjustment screw members 327, and the seventh threaded holes 3212, the second through holes 3261, and the seventh adjustment screw members 327 correspond one-to-one. Further optionally, after the rotation angles of the first pitch seat 326A and the second pitch seat 326B are respectively adjusted by the at least two seventh adjustment screw members 327, the positions of the first pitch seat 326A and the second pitch seat 326B are further fixed by threaded fasteners (i.e., two additional threaded fasteners not shown in FIG. 7 ).

[0079] In this embodiment, second balls 3252 are respectively provided at positions corresponding to the first pitch seat 326A and the second pitch seat 326B. At least two second balls 3252 are used to provide rotational support for different positions of the pitch seat 326, thereby improving the rotational stability. Moreover, the universal rolling of the second balls 3252 reduces the friction between the pitch seat 326 and the moving part, thereby facilitating the smooth rotation of the pitch seat 326.

[0080] In a further embodiment, the receiving groove 3262 corresponding to the first pitch seat 326A is provided with a second limiting structure, which cooperates with the second ball 3252 to limit the position. Optionally, the receiving groove 3262 corresponding to the first pitch seat 326A can be a tapered groove, with the tapered surface of the tapered groove serving as the second limiting structure. The tapered surface contacts the second ball 3252 to ensure that the position of the second ball 3252 relative to the receiving groove 3262 is fixed. Of course, the second limiting structure can also be other limiting structures that can prevent the position of the second ball 3252 relative to the receiving groove 3262 from changing.

[0081] In this embodiment, the second limiting structure is used to limit the position of the second ball 3252 to prevent the second ball 3252 from being displaced relative to the receiving groove 3262 .

[0082] Of course, in other embodiments, the accommodating groove 3262 corresponding to the first pitch seat 326A may not be provided with a second limiting structure. The accommodating groove 3262 corresponding to the first pitch seat 326A may be a cylindrical groove, the diameter of which is less than or equal to the diameter of the second ball 3252. In this way, the second ball 3252 is directly limited by the notch of the accommodating groove 3262.

[0083] In an alternative embodiment, the receiving groove 3262 corresponding to the second pitch seat 326B may be a cylindrical groove; alternatively, the receiving groove 3262 corresponding to the second pitch seat 326B may be a strip-shaped groove extending along the X-direction. Compared to the previous embodiment, the latter embodiment allows the second ball 3252 corresponding to the second pitch seat 326B to have a certain range of motion in the X-direction. After the second ball 3252 is accurately installed in the receiving groove 3262 corresponding to the first pitch seat 326A, to avoid machining errors that may cause the receiving groove 3262 corresponding to the second pitch seat 326B to be unable to accurately install the second ball 3252, the length of the receiving groove 3262 is set larger to ensure that the second ball 3252 can smoothly extend into the receiving groove 3262 corresponding to the second pitch seat 326B.

[0084] Optionally, the accommodating groove 3262 corresponding to the second pitch seat 326B is a trapezoidal groove, that is, in the Y direction, the two opposite side walls of the accommodating groove 3262 are wedge surfaces, so that the second ball 3252 is respectively limited by these two wedge surfaces to prevent the second ball 3252 from moving relative to the accommodating groove 3262 along the Y direction.

[0085] In an alternative embodiment, as shown in FIG7 , the surface of the pitch seat 326 facing the movable plate 321 includes a first surface 326 a and a second surface 326 b , wherein the first surface 326 a and the second surface 326 b are respectively located on opposite sides of the second axis β, and the angle between the first surface 326 a and the second surface 326 b is less than 180°. Alternatively, the lower end surface of the pitch seat 326 includes the first surface 326 a and the second surface 326 b , and either the first surface 326 a or the second surface 326 b is parallel to the upper surface of the pitch seat 326 .

[0086] By screwing the seventh adjusting screw 327, the pitch seat 326 can be rotated relative to the movable plate 321, so that the first surface 326a or the second surface 326b can be in contact with the movable plate 321. When the first surface 326a is in contact with the movable plate 321, the second surface 326b is tilted relative to the movable plate 321; similarly, when the second surface 326b is in contact with the movable plate 321, the first surface 326a is tilted relative to the movable plate 321.

[0087] In this way, by setting the surface of the pitch seat 326 facing the movable plate 321, the pitch seat 326 can be rotated around the second axis β relative to the movable plate 321 by a certain angle. At the same time, the movable plate 321 provides a supporting force for the pitch seat 326, which is conducive to the stable rotation of the pitch seat 326.

[0088] Of course, in other embodiments, the first surface 326a and the second surface 326b may be located in the same plane, that is, the angle between the first surface 326a and the second surface 326b is 180°.

[0089] In a further embodiment, the second adjustment assembly 320 includes a movable plate 321 and a pitch seat 326, wherein the pitch seat 326 is rotatably connected to the movable plate 321 about a second axis β. The adjustment mechanism 300 further includes a third elastic member 329, wherein a first end of the third elastic member 329 is connected to the pitch seat 326, and a second end of the third elastic member 329 is connected to the movable plate 321. Optionally, the third elastic member 329 may be, but is not limited to, a spring. The adjustment mechanism 300 further includes at least two third support shafts 3291, wherein a first end of the third elastic member 329 is fixed to the pitch seat 326 via one of the third support shafts 3291, and a second end of the third elastic member 329 is fixed to the movable plate 321 via the other third support shaft 3291.

[0090] In this embodiment, the third elastic member 329 is utilized to achieve an articulated connection between the pitch seat 326 and the movable plate 321. This allows the pitch seat 326 to rotate relative to the movable plate 321 while preventing complete separation of the pitch seat 326 from the movable plate 321, thereby ensuring a stable connection. Furthermore, in embodiments in which the seventh adjustment screw 327 is provided, the elastic force of the third elastic member 329 facilitates rotation of the pitch seat 326 relative to the movable plate 321 about the second axis β during the process of loosening the seventh adjustment screw 327, thereby facilitating smooth pitch adjustment.

[0091] Optionally, a third elastic member 329 is provided between the first pitch seat 326A and the movable plate 321 and between the second pitch seat 326B and the movable plate 321 , and the third elastic member 329 and the seventh adjusting screw member 327 are respectively located on both sides of the second axis β.

[0092] Of course, in other embodiments, the third elastic member 329 may not be provided between the pitch seat 326 and the movable plate 321, and the relative rotation of the pitch seat 326 and the movable plate 321 can be achieved through the structure of the second ball 3252 mentioned above and the special structure of the surface of the pitch seat 326 facing the movable plate 321.

In other words, the laser light passes through the objective lens 210, is reflected by the reflector 400, and then passes through the light holes of the first aperture 211 and the light holes of the second aperture 510. At this point, the reflected laser light coincides with the optical axis of the objective lens 210. The laser emitting device 500 is adjusted to the target position and fixed.

[0097] S400. Referring to FIG9 , an adjusting mechanism 300 and a zoom lens 220 are installed on the support base 100. The adjusting mechanism 300 is used to adjust the position of the zoom lens 220 so that the laser passes through the zoom lens 220 and the objective lens 210 in sequence and is reflected by the reflector 400 before passing through the first aperture 211 and the second aperture 510 in sequence.

[0098] Optionally, the position of the magnification changer 220 in the X direction is adjusted by screwing the first adjusting screw 315 and / or the second adjusting screw 316, and the rotation of the magnification changer 220 around the first axis α is adjusted by screwing the third adjusting screw 3171 and the fourth adjusting screw 3172. At the same time, the movement position of the magnification changer 220 in the Y direction is adjusted by screwing the fifth adjusting screw 3241 and the sixth adjusting screw 3242, and the rotation of the magnification changer 220 around the second axis β is adjusted by screwing the seventh adjusting screw 327, until the laser passes through the magnification changer 220 and the objective lens 210 in turn and is reflected by the reflector 400 and then passes through the light hole of the first aperture 211 and the light hole of the second aperture 510 in turn, indicating that the optical axis of the objective lens 210, the optical axis of the magnification changer 220 and the reflected light of the laser coincide with each other, so that the optical axis of the objective lens 210 coincides with the optical axis of the magnification changer 220.

[0099] By adopting this adjustment method, the optical axis of the objective lens 210 and the optical axis of the zoom lens 220 are accurately aligned, which is beneficial to accurate imaging of the microscope and improves the imaging effect.
