[0027] The present application is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0028] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various implementations, and the operational steps involved in each embodiment may be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a particular embodiment and do not imply a required composition and / or sequence.

[0029] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0030] See also Figures 1 to 7 The present application provides a floor-standing microscopic measurement device, including a base 100, an operating platform 200 and a seismic isolation connection assembly 300. The base 100 serves as the basic structure of the floor-standing microscopic measurement device itself and provides an installation foundation for other structures. For example, the operating platform 200 is arranged on the base 100. The operating platform 200 can be used to place samples to be observed or other items to be used by the operator during the observation process. The seismic isolation connection assembly 300 is used to connect the base 100 and the operating platform 200. Through the setting of the seismic isolation connection assembly 300, not only can the connection between the base 100 and the operating platform 200 be achieved, but also the shock absorption requirements of the floor-standing microscopic measurement device can be met. The base 100 can generally be placed directly on the ground, or walking wheels can be set at the bottom of the base 100 to facilitate the movement of the floor-standing microscopic measurement device.

[0031] Of course, the seismic isolation connection assembly 300 in the present application is also applicable to other devices with shock absorption requirements, which can not only realize the connection and fixation of at least two components in the device, but also achieve the purpose of shock absorption.

[0032] See also Figure 2 The seismic isolation connection assembly 300 includes a connector 310, a shock-absorbing pad 320, and a shock-absorbing ring 330. The shock-absorbing pad 320 is arranged between the base 100 and the operating platform 200. The connector 310 has a fixed end 311 and an insertion end 312 arranged opposite to each other along its axial direction. The cross-sectional area of ​​the fixed end 311 is larger than the cross-sectional area of ​​the insertion end 312. The insertion end 312 passes through the operating platform 200, the shock-absorbing pad 320, and the base 100. A shock-absorbing ring 330 is provided between the fixed end 311 and the operating platform 200. The connector 310 can realize the connection between the operating platform 200 and the base 100. The setting of the shock-absorbing pad 320 can absorb or buffer vibrations. The setting of the shock-absorbing ring 330 can prevent the fixed end 311 from directly contacting the operating platform 200, thereby avoiding damage to the operating platform 200 when the connector 310 is installed.

[0033] Based on the placement convention of floor-standing micro-measurement devices, the operating platform 200 and base 100 are arranged sequentially from top to bottom along a vertical direction (which can be understood as a first direction Z). To facilitate installation of the connector 310, the insertion end 312 is arranged sequentially along the first direction Z, passing through the operating platform 200, the shock-absorbing pad 320, and the base 100. That is, the connector 310 is installed from top to bottom, and the shock-absorbing ring 330 is positioned between the fixed end 311 and the operating platform 200. Operators can assemble the connector 300 from top to bottom, providing ample working space and simplifying assembly.

[0034] In some embodiments, the operating platform 200 is a marble platform, which has the advantages of a smooth surface, ease of machining, and ease of cleaning. Because marble platforms are inherently brittle, the provision of the shock-absorbing ring 330 can reduce the impact of the connector 310 on the marble platform, preventing excessive forces between the connector 310 and the marble platform during installation that could damage the marble platform.

[0035] Please continue reading Figure 2 The operating platform 200 has a first mounting hole 210 and a second mounting hole 220 arranged in sequence along the first direction Z and connected to each other. The cross-sectional area of ​​the first mounting hole 210 is larger than the cross-sectional area of ​​the second mounting hole 220, so as to form an abutment surface 230 between the first mounting hole 210 and the second mounting hole 220. The insertion end 312 is arranged through the first mounting hole 210 and the second mounting hole 220 in sequence, and the shock-absorbing ring 330 is arranged between the abutment surface 230 and the fixed end 311. During assembly, the shock-absorbing ring 330 is arranged in the first mounting hole 210, and the connecting member 310 passes through the first mounting hole 210, the shock-absorbing ring 330, the second mounting hole 220, the shock-absorbing pad 320 and the base 100 from top to bottom, and the shock-absorbing ring 330 is arranged between the abutment surface 230 and the fixed end 311.

[0036] In some embodiments, the first mounting hole 210 and the second mounting hole 220 may be any structure that adapts to the structural form of the connector 310 , for example, they may be cylindrical.

[0037] In some embodiments, the cross-sectional area of ​​the first mounting hole 210 is larger than the cross-sectional area of ​​the fixed end 311, so that the connector 310 is sunken into the first mounting hole 210. Based on this design, the connector 310 is sunken into the interior of the operating platform 200, which helps to achieve a smooth end surface of the operating platform 200 and improves the aesthetics of the floor-standing microscopic measurement device.

[0038] In some embodiments, the cross-sectional area of ​​the second mounting hole 220 is larger than the cross-sectional area of ​​the insertion end 312. Based on this, after the connector 310 is inserted into the second mounting hole 220, it is spaced apart from the inner wall thereof, which can further reduce the impact of the connector 310 on the operating platform 200 (especially the marble platform).

[0039] In some embodiments, the cross-sectional area of ​​the fixed end 311 of the connector 310 is also smaller than the cross-sectional area of ​​the shock-absorbing ring 330, which helps to completely isolate the connector 310 and the operating platform 200 and effectively avoid the impact of the connector 310 on the operating platform 200 (especially the marble platform).

[0040] In some embodiments, in order to further achieve aesthetics, the seismic isolation connection assembly 300 also includes a sealing cover 340, which is used to seal the first mounting hole 210. The first mounting hole 210 is a structure with openings at both ends to facilitate the installation and removal of the connector 310. Due to its open setting, dust or debris is easily accumulated in the first mounting hole 210. The setting of the sealing cover 340 can prevent this phenomenon.

[0041] In some embodiments, to simplify the installation process and improve assembly efficiency, the connector 310 and base 100 are threadedly connected. Since the first and second mounting holes 210, 220 do not contact the connector 310, the insertion end 312 is threadedly connected to the base 100. Specifically, the insertion end 312 is provided with external threads, and the base 100 is provided with a threaded hole 110. In this embodiment, the connector 310 can be a screw or threaded rod structure, as its materials are readily available, cost-effective, and easy to assemble and disassemble.

[0042] Of course, in other embodiments, the connector 310 and the base 100 may also be connected by gluing, snapping, or plugging.

[0043] In some embodiments, the connector 310 further includes a retaining ring 350, which is disposed between the damping ring 330 and the fixed end 311. The provision of the retaining ring 350 can increase the contact area between the connector 310 and the damping ring 330, further enhancing the shock absorption effect. The cross-sectional area of ​​the retaining ring 350 can be larger than that of the fixed end 311 and smaller than that of the damping ring 330, thereby securing the connector 310 in place.

[0044] In some embodiments, the shock-absorbing ring 330 and the shock-absorbing pad 320 can be made of elastic silicone material or elastic porous fiber material (such as a sponge pad), which can achieve the purpose of absorbing and buffering vibrations.

[0045] In some embodiments, multiple seismic isolation connection assemblies 300 are provided, and the multiple seismic isolation connection assemblies 300 are evenly arranged along the cross-section of the operating platform 200. For example, there may be 4, 6, or 8 seismic isolation connection assemblies 300, and there are no excessive restrictions here. The multiple seismic isolation connection assemblies 300 are evenly arranged on the operating platform 200, so that the operating platform 200 and the base 100 are evenly stressed when connected, and the operating platform 200 can also be evenly damped.

[0046] In some embodiments, the floor-standing microscopic measurement device further includes a support arm 500 and a measurement mechanism 600 . The support arm 500 is disposed on the operating platform 200 , and the measurement mechanism 600 is disposed on the support arm 500 .

[0047] In some embodiments, the floor-standing microscopic measurement device further includes a motion platform 400, which is disposed on the operating platform 200 and is used to place a sample to be observed. To facilitate observation of different positions of the sample, a first drive mechanism (not shown) is disposed between the motion platform 400 and the operating platform 200. The first drive mechanism includes a first drive unit that can drive the motion platform 400 to reciprocate relative to the operating platform 200 in a second direction X, and a second drive unit that can drive the motion platform 400 to reciprocate relative to the operating platform 200 in a third direction Y. The second direction X and the third direction Y are both perpendicular to the first direction Z. Based on the usage and placement practices of the floor-standing microscopic measurement device, the plane containing the first direction Z and the second direction X is defined as a horizontal plane.

[0048] See also Figure 3 The measuring mechanism 600 is a critical precision structure in the floor-standing micro-measurement device, comprising an outer housing 610, a lens barrel (not shown), a lens 620, and an optical imaging lens assembly (not shown). Because the lens 620 needs to be moved toward or away from the sample during sample observation, the floor-standing micro-measurement device also includes a second drive mechanism (not shown). This second drive mechanism includes a third drive unit that drives the measuring mechanism 600 to reciprocate in the first direction Z and a fourth drive unit that drives the lens 620 to reciprocate in the first direction Z. Specifically, the third drive unit performs coarse adjustment of the displacement in the first direction Z, and the fourth drive unit performs fine adjustment of the displacement in the first direction Z.

[0049] In some embodiments, the first, second, third, and fourth drive units can each be a linear drive motor or a linear cylinder. To prevent resonance between the drive units and the floor-standing micro-measurement device during movement, thereby generating noise that could affect measurement results and damage the floor-standing micro-measurement device, the first, second, third, and fourth drive units can be servo motors.

[0050] In order to effectively ensure the stable operation of the measuring mechanism 600, please refer to Figure 4In some embodiments, the support arm 500 is provided with a connecting block 700, and the connecting block 700 is provided with a sliding track 710. The sliding track 710 extends along the first direction Z. Accordingly, the measuring mechanism 600 is provided with a slider 630, which is slidably connected to the sliding track 710. The output end of the third drive unit is connected to the slider 630, thereby ensuring stable operation of the measuring mechanism 600 along the first direction Z. Two corresponding sliding tracks 710 and two corresponding sliders 630 can be provided to further ensure stable operation of the measuring mechanism 600. Of course, in other embodiments, the positions of the slider 630 and the sliding track 710 can be reversed, that is, the sliding track 710 is provided on the measuring mechanism 600, and the slider 630 is provided on the connecting block 700.

[0051] To ensure the stability of motion along the first direction Z, a floor-standing microscopic measurement device generally requires a balancing mechanism 800. Due to the heavy weight, bulk, and high center of gravity of floor-standing microscopic measurement devices, the existing method of installing the balancing mechanism 800 at the location of the lens 620 of the measurement mechanism 600 is not conducive to lowering the center of gravity and also has the disadvantage of requiring a large amount of space to install the balancing mechanism 800. The present application creatively adjusts the weight of the balancing mechanism 800 to be located within the base 100 of the mounting base, which not only meets the requirement of balancing gravity but also lowers the center of gravity.

[0052] Please continue reading Figure 4 The balancing mechanism 800 includes a pulley set 810 and a counterweight block 820. The counterweight block 820 is arranged in the base 100 and is connected to the measuring mechanism 600 through the pulley set 810. The setting of the counterweight block 820 can balance the weight of the measuring mechanism 600, so that the center of gravity of the entire floor-standing microscopic measuring device is lowered, avoiding the situation of top-heavy and low stability.

[0053] In some specific embodiments, the pulley assembly 810 includes multiple guide pulleys 811 and a connecting rope 812 (which can be a steel wire rope). One end of the connecting rope 812 is connected to the slider 630, and the other end crosses multiple guide pulleys 811 in sequence and then is connected to the counterweight block 820 set in the base 100. The guide pulley 811 is set to guide the direction of the connecting rope 812.

[0054] See also Figure 5In one embodiment, the guide pulleys 811 include a first guide pulley 8111, a second guide pulley 8112, a third guide pulley 8113, a fourth guide pulley 8114, and a fifth guide pulley 8115. The arrangement of the plurality of guide pulleys 811 allows the connecting rope 812 to be guided to the counterweight 820 disposed within the base 100, depending on the structural form of the floor-standing microscopic measurement device. In this embodiment, the first guide pulley 8111 and the second guide pulley 8112 are disposed on the connecting block 700 along a first direction Z, and the third guide pulley 8113 and the fourth guide pulley 8114 are offset by a first predetermined distance relative to the first and second pulleys along a third direction Y (or second direction X). The first guide pulley 8111, the second guide pulley 8112, and the third guide pulley 8113 are disposed within the outer shell 610, and the third guide pulley 8113 and the fourth guide pulley 8114 are disposed sequentially along the first direction Z, and the fourth guide pulley 8114 and the fifth guide pulley 8115 are disposed sequentially along the first direction Z. The guide pulley 8115 is arranged inside the support arm 500, or on the surface of the support arm 500. The fifth guide pulley 8115 is offset by a second preset distance relative to the fourth pulley along the third direction Y (or the second direction X). The connecting rope 812 is arranged along the first guide pulley 8111, the second guide pulley 8112, the third guide pulley 8113, the fourth guide pulley 8114 and the fifth guide pulley 8115. The weight of the measuring mechanism 600 located at a high place can be balanced to the counterweight block 820 located in the base 100 located at a low place, so as to achieve the purpose of lowering the center of gravity.

[0055] Please continue reading Figure 5 In order to further effectively ensure the compactness of the structure of the floor-standing microscopic measurement device, reduce its occupied space, and reduce the impact of the pulley group 810 on the measuring mechanism 600, etc., the surface of the support arm 500 can be recessed to form a mounting groove 510 for mounting the fourth guide pulley 8114 and the fifth guide pulley 8115.

[0056] See also Figure 6 Since an electronic control system may be installed in the base 100, a sixth guide pulley 8116 and a seventh guide pulley 8117 may also be installed in the base 100 to avoid the electronic control system. Based on the position of the electronic control system, the sixth guide pulley 8116 and the fifth guide pulley 8115 are arranged along the first direction Z, and the seventh guide pulley 8117 is offset from the sixth guide pulley 8116 by a third predetermined distance in the third direction Y (or the second direction X). This allows the connecting rope 812 to cross the electronic control system and connect to the counterweight 820.

[0057] Please continue reading Figure 6In order to facilitate the installation of the sixth guide pulley 8116 and the seventh guide pulley 8117, a mounting frame 900 is provided in the base 100, and the mounting frame 900 includes a first part 910 and a second part 920 arranged perpendicular to each other. The first part 910 extends along the third direction Y (or the second direction X), and the second part 920 extends along the first direction Z, so that the mounting frame 900 is roughly L-shaped. The first part 910 is connected to the inner wall of the base 100, and the second part 920 is arranged at the free end of the first part 910. The first part 910 is arranged across the electronic control system. The sixth guide wheel is arranged at the position where the first part 910 and the base 100 are connected, and the seventh guide wheel is arranged at the connection between the second part 920 and the first part 910.

[0058] Of course, the number and position of the guide pulleys 811 are not limited to the above description. Specifically, they can be arranged according to the specific structure of the floor-standing microscopic measurement device so that the connecting rope 812 can be guided to the counterweight 820 without affecting the functions of other components. The number and weight of the counterweights 820 can be set according to the deadweight of the floor-standing microscopic measurement device. The number of connecting ropes 812 can also be multiple, and the specific setting is made according to the stress conditions of the entire pulley group 810. In order to facilitate the balance of the entire floor-standing microscopic measurement device on the horizontal plane, two counterweights 820 can be provided, and two connecting ropes 812 are also provided, both of which are connected to the counterweight 820.

[0059] To facilitate the entry of the connecting rope 812 from the support arm 500 into the base 100, a first through hole 520 and a second through hole (not shown) are respectively provided at corresponding positions of the support arm 500 and the base 100. The shapes of the first through hole 520 and the second through hole match the shape of the connecting rope 812 and can be circular or rectangular, without further limitation.

[0060] To achieve linkage between the counterweight 820 and the measuring mechanism 600, a connecting rope 812 can be connected to the slider 630. The balancing mechanism 800 also includes a balancing rail 830. The counterweight 820 is slidably connected to the balancing rail 830. The balancing rail 830 is disposed within the base 100 and is parallel to the sliding track 710. Both extend along the first direction Z. After the slider 630 and the counterweight 820 are connected by the connecting rope 812, the weight of the measuring mechanism 600 can be balanced by the counterweight 820. Depending on the location of the counterweight 820, the balancing rail 830 can be disposed on the inner wall of the base 100 or on the second portion 920 of the mounting frame 900.

[0061] See also Figure 7In order to further lower the center of gravity of the floor-standing microscopic measurement device, the balancing mechanism 800 further includes a plurality of counterweight plates 840. The plurality of counterweight plates 840 are evenly arranged along the bottom plane of the base 100. The number of counterweight plates 840 can be 2, 3, or 4, etc. The specific number and weight of each counterweight plate 840 are determined based on the purpose of lowering the center of gravity, and are not subject to excessive restrictions herein.

[0062] At the same time, the above technical solution can be applied to various measuring instruments, including but not limited to desktop confocal microscopes, white light interferometers or imagers, etc.

[0063] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
