Description

Technical Field

[0001] The present invention belongs to the technical field of microscope adjustment, and more particularly, relates to a long-arm microscope objective switching device with adjustable damping and shock absorption. Background Art

[0002] A micro-area optical measurement system is an instrument used for high-precision optical measurement of microscopic areas. By focusing a light beam onto a tiny region, it exploits the interaction between light and matter, such as reflection, refraction, scattering, and absorption, to obtain information about the optical properties of that region, enabling analysis of the material's structure, composition, and properties. In experiments involving challenging environments such as high temperature, high pressure, or strong magnetic fields, a long-arm microscope can position the main body in a relatively safe area, while the long arm extends the probe into the challenging environment for micro-area measurement. This ensures measurement accuracy while protecting operators and equipment from the effects of the challenging environment.

[0003] In micro-area optical measurement, due to the high precision required, even minute vibrations can significantly affect the measurement. For example, vibrations can cause the focus position to shift, affecting the precise measurement of a micro-area. However, the length of the probe arm significantly impacts the stability and ease of operation of micro-area optical measurement. An excessively long probe arm can result in inflexible operation, hindering the operator's control of the microscope and sample placement. Furthermore, the microscope's overall structural instability makes it susceptible to external vibrations. These vibrations can cause minute displacements of the microscope and sample, resulting in blurred images or inaccurate measurements.

[0004] In the existing technology, the shaking of the long arm is avoided only by strengthening the material properties of the long arm, so that the microscope and the sample are always in focus and the problem of blurred observation is avoided. However, making improvements in materials requires a greater workload, and the cost of high-strength materials is higher. When solving more minor shaking, the requirements for materials will be higher, and the cost and effect will be very different. Therefore, there is a need for a long-arm microscope objective switching device and debugging method with adjustable damping and shock absorption, which uses a smaller economic cost to provide a better shock absorption effect. Summary of the Invention

[0005] In response to the above-mentioned defects or improvement needs of the prior art, the present invention provides a long-arm microscope objective switching device and debugging method with adjustable damping and shock absorption. The long-arm rod is moved up, down, left, and right through the two-axis sliding unit to adjust the position of the microscope objective at its bottom end. The sliding damping adjustment unit is used to enable the shock absorber to provide thrust to the long-arm rod so that it is on one side of the elastic deformation range, thereby avoiding slight shaking due to vibration during subsequent use, which affects the observation results of the microscope objective.

[0006] To achieve the above objectives, a long-arm microscope objective lens switching device with adjustable damping and shock absorption is provided, comprising: a supporting unit, a damping adjustment unit, a two-axis sliding unit, and an objective lens mounting unit;

[0007] The support unit includes two upper and lower parallel support plates, and the two support plates are connected by a side plate;

[0008] The objective lens mounting unit includes a long arm rod, the top end of which is fixed to a two-axis sliding unit;

[0009] The two-axis sliding unit is arranged on the upper support plate of the support unit, and the long arm rod is driven to move by the two-axis sliding unit;

[0010] The damping adjustment unit is tilted on the lower support plate of the support unit, and a shock absorber is provided at its front end. The shock absorber provides thrust to the long arm rod by sliding so that it is on one side of the elastic deformation range, avoiding slight shaking due to vibration during subsequent use.

[0011] Furthermore, the damping adjustment unit further includes a pushing base plate, a pushing slide and a slider;

[0012] The pushing base plate is transverse to the back of the long arm rod, fixed to the lower support plate, and is tilted to form an angle with the back of the long arm rod;

[0013] The pushing slide is arranged on the pushing bottom plate, and the sliding block is arranged on the pushing slide and moves along the axial direction of the pushing slide.

[0014] Furthermore, U-shaped grooves are provided at both ends of the pushing base plate, and relative sliding occurs between the pushing base plate and the fixing holes on the lower support plate through the U-shaped grooves, ensuring that the pushing slide and the side of the lower support plate are fixed at a slight angle.

[0015] Furthermore, the shock absorber is arranged at one end of the slider close to the long arm rod, and its front end contacts the back of the long arm rod. When the slider moves, due to the angle between the pushing base plate and the long arm rod, the pushing force of the front end of the shock absorber on the long arm rod changes. When the thrust increases, the long arm rod approaches its shaking limit position, thereby reducing the shaking caused by vibration.

[0016] Furthermore, the shock absorber is provided at one end of the slider, and comprises a push shell fixedly connected to the end of the slider, a ball provided at the front end of the push shell, and a spring provided in the push shell;

[0017] The spring is arranged in the cylindrical cavity, one end of which is fixed to the bottom surface of the push shell, and the other end is in contact with the ball to provide elastic force to the ball;

[0018] The microcontroller controls the slider to drive the shock absorber to produce a small lateral displacement along the push slide, so that the front end of the shock absorber contacts the long arm rod and applies a lateral elastic force to it. The elastic force between the long arm rod and the shock absorber provides damping to eliminate the small vibrations at the end of the long arm rod.

[0019] Furthermore, the two-axis sliding unit includes a vertical slide and a horizontal slide, and the vertical slide is connected to the long arm to drive it to move vertically;

[0020] The vertical slide and the slider are linked so that after initial commissioning, the slide lowers the microscope objective lens to its desired position, and the slider automatically moves to the appropriate damping position. The single-chip microcomputer control system records multiple sets of data corresponding to different environmental vibrations, allowing for rapid response and adjustment when the ambient vibration changes.

[0021] Furthermore, the bottom end of the vertical adjustment frame is also provided with an internal and external threaded sleeve, which is connected to the vertical adjustment frame through threads, and the screwing depth of the internal and external threaded sleeve in the vertical adjustment frame is adjusted by threads to adjust the overall length.

[0022] Furthermore, after the shock absorber applies elastic force to the long arm rod, the first adjusting bolt and the second adjusting bolt on the vertical adjustment frame are adjusted to keep the microscope objective lens vertical and without deflection, and the vibration in the micro area is observed under microscopic imaging. The slider is fine-tuned to change the elastic force of the shock absorber. After eliminating the micro-vibration, the vertical adjustment frame is adjusted again to keep the microscope objective lens vertical and without deflection.

[0023] Furthermore, the horizontal slide is fixed to the upper support plate of the support unit through a slide bottom plate, and the vertical slide is connected through a slide connecting plate;

[0024] The vertical slide and the horizontal slide generate vertical and horizontal movements respectively, so that the microscope lens arranged at the bottom end of the long arm rod cuts into or out of the detection instrument.

[0025] In general, the above technical solutions conceived by the present invention can achieve the following beneficial effects compared with the prior art:

[0026] 1. The long-arm microscope objective switching device of the present invention uses a two-axis sliding unit to achieve the up, down, left, and right movement of the long arm to adjust the position of the microscope objective at its bottom end. The sliding damping adjustment unit causes the shock absorber to provide thrust to the long arm to keep it on one side of the elastic deformation range, thereby avoiding slight shaking due to vibration during subsequent use, which may affect the observation results of the microscope objective.

[0027] 2. In the long-arm microscope objective switching device of the present invention, the top end of the long-arm rod has been fixed between the two-axis sliding unit, and the microscope objective is arranged at the bottom end of the long-arm rod. Due to the long length of the long-arm rod, slight vibration will cause the long-arm rod near the microscope objective end to shake. A damping adjustment unit is provided at the end of the long-arm rod near the microscope objective, which provides a thrust force to the long-arm rod and applies elastic damping to the long-arm rod through the damping adjustment unit, so that the shock absorber absorbs vibration energy and reduces the amplitude of periodic vibration caused by the external environment. In addition, the elastic restoring force provided by the damping unit can quickly attenuate non-periodic vibrations caused by other human factors, so as to solve the problem of shaking of the long-arm objective due to vibration.

[0028] 3. In the long-arm microscope objective switching device of the present invention, as the slider moves, the force between the shock absorber and the long-arm lever gradually increases, and the friction between the two also gradually increases. In this case, the movement of the slider can damage the long-arm lever, or even make it unable to move, affecting the damping adjustment effect. The provision of the ball bearing reduces the friction during the movement process, making it easier to reach the set damping position.

[0029] 4. The long-arm microscope switching device of the present invention uses a two-axis sliding unit to adjust the height and position of the microscope objective lens so that it is precisely placed in the detection instrument. The height of the microscope objective lens is further adjusted using an internal and external threaded sleeve to accommodate the setting requirements of microscope objective lenses with different focal lengths. The angle of the microscope objective lens is adjusted to the optimal observation angle using a vertical adjustment frame to increase the observation accuracy of the microscope objective lens.

DETAILED DESCRIPTION

[0038] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to illustrate the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0039] Example 1

[0040] like Figure 1-6As shown, an embodiment of the present invention provides a long-arm microscope objective switching device with adjustable damping and shock absorption, comprising: a support unit 1, a damping adjustment unit 2 provided on the support unit 1, a two-axis sliding unit 3 provided on the support unit 1, and an objective lens mounting unit 4 provided on the two-axis sliding unit 3. The support unit 1 comprises two upper and lower support plates arranged in parallel, the two support plates being connected by a side plate so that the upper and lower support plates are always kept in parallel, and the support unit 1 is fixed on a table. The objective lens mounting unit 4 comprises a long-arm rod 41, the top end of the long-arm rod 41 being fixed to the two-axis sliding unit 3, the bottom end of the long-arm rod 41 being fixed with a microscope objective lens 5, the two-axis sliding unit 3 being provided on the upper support plate, and the long-arm rod 41 being moved up, down, left, and right by the two-axis sliding unit 3 to adjust the position of the microscope objective lens 5 at its bottom end. The damping adjustment unit 2 is arranged on the lower support plate. The damping adjustment unit 2 is tilted and a shock absorber 24 is provided at its front end. The shock absorber 24 provides thrust to the long arm rod 41 by sliding so that it is on one side of the elastic deformation range, thereby avoiding slight shaking due to vibration during subsequent use, which affects the observation results of the microscope objective lens 5.

[0041] The two-axis sliding unit 3 includes a vertical slide 31, a slide connecting plate 32, a transverse slide 33, and a slide base 34. The slide base 34 is fixed to the upper support plate and laterally disposed on the back of the long arm 41. The transverse slide 33 includes a transverse track plate and a transverse slide plate fixed to the top surface of the slide base 34. Parallel slide rails are provided on either side of the transverse track plate, each having an I-shaped cross-section. A guide rod is provided between the two slide rails. The guide rod is a square rod with a groove on its top side and a screw inside. The screw rotates within the guide rod. A motor is provided at one end of the guide rod, and the motor's output shaft is connected to the screw, which is driven by the motor to rotate the screw. Grooves are provided on either side of the transverse slide plate. The grooves fit over the slide rails. The grooves and the slide rails cooperate to enable the transverse slide plate to move along the transverse track plate. Cylindrical grooves are provided in the middle of the grooves on either side of the transverse slide plate. These cylindrical grooves have threads that cooperate with the screw, driving the transverse slide plate to move laterally when the screw rotates. Limiting plates are provided at both ends of the guide rod on the transverse track plate, and the transverse slide plate is limited by the limiting plates.

[0042] The vertical slide 31 is longitudinally arranged on the back of the long arm rod 41, and includes a vertical track plate and a vertical slide plate. Parallel slide rails are provided on both sides of the vertical track plate, and the cross-section of the slide rails is I-shaped. A guide rod is also provided between the slide rails on both sides. The guide rod is a square rod with a groove on the top side and a screw rod inside. The screw rod rotates in the guide rod. A motor is provided at one end of the guide rod. The output shaft of the motor is connected to the screw rod, and the screw rod is driven to rotate by the motor. Grooves are provided on both sides of the horizontal slide plate. The grooves are sleeved on the slide rails. Through the cooperation of the grooves and the slide rails, the vertical slide plate moves along the vertical track plate. A cylindrical groove is provided in the middle of the grooves on both sides of the vertical slide plate. The cylindrical groove is provided with a thread, which cooperates with the screw rod. When the screw rod rotates, it pushes the vertical slide plate to move vertically.

[0043] As a further preferred embodiment, the vertical slide 31 and the horizontal slide 33 are connected by a slide connecting plate 32, which is an L-shaped plate, the bottom horizontal plate of which is fixedly connected to the horizontal slide, and the side vertical plate is fixedly connected to the vertical track plate, so that the vertical slide 31 slides horizontally following the horizontal slide.

[0044] As a further preferred embodiment, the top end of the long arm rod 41 is fixedly connected to the vertical slide plate, and moves along with the vertical slide plate in the up-down and left-right directions.

[0045] The damping adjustment unit 2 includes a push base plate 21, a push slide 22, a slider 23, and a shock absorber 24. The push base plate 21 is fixed to the lower support plate transversely to the back of the long arm 41 and is tilted to form an angle with the back of the long arm 41. The push slide 22 is mounted on the push base plate 21 and fixedly connected to the push base plate 21. A chute is provided on the top surface of the push slide 22, with inner grooves on both sides of the chute. A rack is provided on the bottom surface of the chute along the length of the chute. The slider 23 is mounted in the chute of the push slide 22 and is perpendicular to the push slide 22. Two limit bars are provided on its bottom surface, which cooperate with the inner grooves on both sides of the chute to achieve position limiting. A drive slot is provided at the bottom end of the slider 23, which houses a built-in motor. A gear is provided at the output end of the motor. The edge of the gear protrudes from the drive slot to cooperate with the rack. The motor drives the gear to rotate, causing it to move on the rack. The shock absorber 24 is provided at one end of the slider 23 close to the long arm rod 41, and its front end contacts the back of the long arm rod 41. When the slider 23 moves, due to the angle between the pushing base plate 21 and the long arm rod 41, the pushing force of the front end of the shock absorber 24 on the long arm rod 41 changes. When the thrust increases, the long arm rod 41 approaches the limit position of its shaking, thereby reducing the shaking caused by vibration.

[0046] It is understood that the top end of the long arm 41 is fixed to the two-axis sliding unit 3, while the microscope objective lens 5 is located at the bottom end of the long arm 41. Due to the long length of the long arm 41, even slight vibrations will cause the end of the long arm 41 near the microscope objective lens 5 to wobble. A damping adjustment unit 2 is provided at the end of the long arm 41 near the microscope objective lens 5. The damping adjustment unit 2 provides a thrust force to the long arm 41, so that the elastic deformation of the long arm 41 reaches its limit and is fixed. Therefore, it no longer deforms when subjected to vibration energy, thus solving the problem of its shaking caused by vibration.

[0047] The shock absorber 24 is mounted at one end of the slider 23 and includes a thrust shell 241 fixedly connected to the end of the slider 23, a ball 242 mounted at the front end of the thrust shell 241, and a spring 243 disposed within the thrust shell 241. The thrust shell 241 is a hollow cylinder with a cylindrical cavity at its center. An annular retaining plate is located at its front end. The ball 242 has the same diameter as the cylindrical cavity, while the annular retaining plate has a smaller diameter than the ball 242. The spherical surface of the ball 242 passes through the annular retaining plate, which holds it in place. The spring 243 is located within the cylindrical cavity, with one end fixed to the bottom surface of the thrust shell 241 and the other end in contact with the ball 242, providing elastic force to the ball 242.

[0048] The two ends of the pushing base plate 21 are provided with U-shaped grooves, through which the pushing base plate 21 and the fixing holes on the lower support plate can slide relative to each other, ensuring that the pushing slide 22 and the side of the lower support plate are fixed at a slight angle.

[0049] The slider 23 is controlled by the single chip computer to move along the slide groove of the push slide 22, driving the shock absorber 24 to produce a small lateral displacement, so that the front end of the shock absorber 24 contacts the long arm rod 41 and applies a lateral elastic force to it. The elastic force between the long arm rod 41 and the shock absorber 24 provides damping to eliminate the small vibrations at the end of the long arm rod 41.

[0050] It is understood that as the slider 23 moves, the force between the shock absorber 24 and the long arm 41 gradually increases, and the friction between the two gradually increases. In this case, the movement of the slider 23 may damage the long arm 41, or even make it unable to move, affecting the damping adjustment effect. The provision of the ball 242 reduces the friction during the movement process, making it easier to reach the set damping position.

[0051] The bottom end of the long arm 41 is also provided with a horizontal plate with multiple mounting holes and a circular hole at its center. The objective lens mounting unit 4 also includes a vertical adjustment bracket 42 mounted on the horizontal plate at the bottom end of the long arm 41. The vertical adjustment bracket 42 includes a pitch bracket 421 and a yaw bracket 424. The pitch bracket 421 and the yaw bracket 424 are arranged in a superimposed manner, and their adjustment directions are perpendicular to each other. The pitch bracket 421 is provided with a first top bead 422 and a first adjustment bolt 423. The first top bead 422 is located at the front end of the first adjustment bolt 423. By rotating the first adjustment bolt 423, the depth to which the first top bead 422 is inserted into the pitch bracket 421 is controlled to adjust the angle of the pitch bracket 421. The yaw bracket 424 is provided with a second top bead 425 and a second adjusting bolt 426. The second top bead 425 is provided at the front end of the first adjusting bolt 423. By rotating the second top bead 425, the depth of the second top bead 425 inserted into the yaw bracket 424 is controlled to adjust the angle of the yaw bracket 424.

[0052] It can be understood that the vertical adjustment frame 42 compensates for the change in the angle of the end objective lens caused by the lateral thrust of the damping adjustment unit 2 on the long arm rod 41 .

[0053] The bottom end of the vertical adjustment frame 42 is also provided with an internally and externally threaded sleeve 44, which is connected to the vertical adjustment frame 42 via threads. The screwing depth of the internally and externally threaded sleeve 44 into the vertical adjustment frame 42 is adjusted by the threads to adjust the overall length. The internally and externally threaded sleeve 44 and the vertical adjustment frame 42 are reinforced by an internally threaded retaining ring 43.

[0054] The microscope objective lens 5 is connected to the internal and external threaded sleeve 44 via threads, so as to achieve portable disassembly, assembly and replacement.

[0055] It can be understood that the height and position of the microscope objective lens 5 are adjusted by the two-axis sliding unit 3 so that it is just set in the detection instrument 6, and the height of the microscope objective lens 5 is adjusted again by the internal and external threaded sleeves 44 to adapt to the setting requirements of microscope objective lenses 5 with different focal lengths. The angle of the microscope objective lens 5 is adjusted by the vertical adjustment frame 42 to adjust it to the optimal observation angle to increase the observation accuracy of the microscope objective lens 5.

[0056] The two ends of the pushing base plate 21 are provided with U-shaped grooves, through which the pushing base plate 21 and the fixing holes on the lower support plate can slide relative to each other, ensuring that the pushing slide 22 and the side of the lower support plate are fixed at a slight angle.

[0057] It is understandable that, since different microscope objective lenses 5 have different weights and lengths, and are located at the end of the long arm rod 41, the micro-vibration effect of the system at this time will produce large differences for different microscope objective lenses 5. In addition, when the vertical slide 31 drives the long arm rod 41 to move in the vertical direction, the different heights will cause the shock absorber 24 to push the long arm rod 41 at different positions, which will affect the shock absorption effect. Therefore, the position of the vertical slide 31 and the slider 23 are linked so that after the initial debugging is completed, the vertical slide 31 drives the microscope objective lens 5 to descend to the corresponding position, and the slider 23 automatically moves to the appropriate shock absorption position. The single-chip microcomputer control system records multiple sets of data corresponding to different environmental vibrations, and when the environmental vibration changes, it responds quickly and makes corresponding adjustments.

[0059] like Figure 7 As shown, an embodiment of the present invention provides a debugging method for a long-arm microscope objective lens switching device with adjustable damping and shock absorption, which specifically includes the following steps:

[0060] S100, driving the two-axis sliding unit 3 so that the lower end of the long arm rod 41 penetrates into the interior of the detection instrument 6;

[0061] S200, controlling the screwing depth of the internal and external threaded sleeve 44 into the lower thread of the vertical adjustment frame 42, and driving the vertical slide 31 to make the microscope objective lens 5 focus on the sample surface;

[0062] S300, driving the damping adjustment unit 2, so that the shock absorber 24 applies a lateral elastic force to the long arm rod 41;

[0063] S400, adjusting the first adjusting bolt 423 and the second adjusting bolt 426 on the vertical adjustment frame 42 to keep the microscope objective lens 5 vertical and stable;

[0064] S500, observing the vibration in the micro area under microscopic imaging, and fine-tuning the slider 23 to change the elastic force of the shock absorber 24 to eliminate the micro vibration;

[0065] S600, adjust the vertical adjustment frame 42 again to keep the microscope objective lens 5 vertical and not deflected;

[0066] S700, recording the positions of the vertical slide 31 and the horizontal slide 33 by the single chip microcomputer;

[0067] S800 , move the slider 23 in the reverse direction to release the elastic force of the shock absorber 24 on the long arm 41 , drive the two-axis sliding unit 3 , and move the microscope objective lens 5 out of the detection instrument 6 .

[0068] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
