Description

[Technical field]

[0001] The present invention relates to a micro distance adjustment mechanism and a microscope apparatus to which this micro distance adjustment mechanism is applied. [Background technology]

[0002] Traditionally, the term microscope often refers to an optical microscope, which is used to observe the microscopic structures of microorganisms, cells, and materials. The image of the sample is magnified mainly by a lens and sent to the eye or an imaging device for observation.

[0003] In recent years, with the spread of smart communication devices (e.g., smartphones) and the improvement of the camera functions installed in smart communication devices, many types of microscope devices are now available on the market, which can be mounted on the camera lens of a smart communication device to observe samples, thereby achieving the purpose of a portable compact microscope device.

[0004] However, while the conventional microscope device effectively reduces the overall structure to achieve the goal of compactness, it can also observe the sample through the camera lens of the smart communication device. However, when observing the sample, the relative positions of the microscope device and the smart communication device remain fixed, so when the thickness of the sample changes (different samples have different thicknesses, or different parts of the same sample have different thicknesses) or the placement position is not good, the observation through the lens of the micro microscope cannot be performed at the best observation position, and the user needs to reposition the sample or even remake the sample, which is very inconvenient for the user. Furthermore, since the focal length of the objective lens of the microscope device is fixed and the distance between the objective lens and the stage (e.g., the slide placement table) is also fixed, when it is applied to the observation of a three-dimensional sample, usually only the surface or partial cross-section image of the three-dimensional sample can be observed. In other words, if a user wants to observe different cross-sections of a three-dimensional sample or a plurality of three-dimensional samples with different thicknesses or heights, usually the user needs to reposition or remake the sample to be observed to achieve the purpose of observing the three-dimensional sample, but the three-dimensional sample cannot be observed quickly and conveniently.

[0024] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the present invention will now be described with reference to the accompanying drawings, in which like elements are designated by like reference numerals.

[0025] Please refer to Figures 1A and 1B. Figure 1A is a diagram showing a microscope device 10 according to an embodiment of the present invention mounted on a smart communication device 50, and Figure 1B is an exploded view of the microscope device 10 of Figure 1A.

[0026] The microscope apparatus 10 according to the embodiment of the present invention includes an objective lens unit 1 and a micro-distance adjustment mechanism 2 that adjusts the micro-distance of the objective lens unit 1 in an optical path P. When performing the micro-distance adjustment, the range of micro-distance adjustment that the micro-distance adjustment mechanism 2 can provide is within 0.1 mm to 3.5 mm.

[0027] 1A and 1B, the microscope apparatus 10 further includes a fixture 3, the micro-distance adjustment mechanism 2 is coupled to the fixture 3, the fixture 3 is provided with an opening O located in the optical path P, and the objective lens unit 1 corresponds to the opening O. In detail, the fixture 3 holds an image capture device 51 of the smart communication device 50, the image capture device 51 is located in the optical path P while being adjacent to the objective lens unit 1.

[0028] Also see Fig. 1C. In this embodiment, the microscope apparatus 10 further includes a sample mounting module 4, which is movably connected to the micro-distance adjustment mechanism 2, and the sample mounting module 4 has a sample observation area 41 adjacent to the objective lens unit 1. In one embodiment, the sample mounting module 4 is movably connected to the micro-distance adjustment mechanism 2 in a magnetic manner, but the sample mounting module 4 may be movably connected to the micro-distance adjustment mechanism 2 in other ways, which is not limited by the present invention.

[0029] The following describes the operation procedure for observing a sample using the microscope device 10 of this embodiment. First, the user inserts the objective lens unit 1 into the micro-distance adjustment mechanism 2, and then connects the micro-distance adjustment mechanism 2 to the fixture 3. In this embodiment, the objective lens unit 1 is inserted into the micro-distance adjustment mechanism 2 by a screw-in connection method, and the micro-distance adjustment mechanism 2 is connected to the fixture 3 by a screw-in connection method. However, the present invention may insert the objective lens 1 into the micro-distance adjustment mechanism 2 and connect the micro-distance adjustment mechanism 2 to the fixture 3 by other similar or different methods, and the present invention is not limited thereto.

[0030] Next, the user places the observation sample in the sample observation area 41 of the sample placement module 4. In one embodiment, the sample is placed on a slide glass, and after selecting whether to cover it with a cover glass, the prepared sample (preparation) is placed in the sample observation area 41 (see FIG. 1C). In another embodiment, the sample is collected with a sticker, and the sticker containing the sample is directly attached to the sample observation area 41 (not shown in the figure). In yet another embodiment, the liquid containing the sample is directly dripped into the sample observation area 41, and the sample observation area 41 is provided with a receiving structure that can receive the liquid sample (not shown in the figure). It should be noted that the present invention may also use other methods to place the sample in the sample observation area 41 of the sample placement module 4, and is not limited to this invention. In addition, this embodiment does not limit the sample to be observed, and examples include leather, jewelry, jewels, biological samples, and skin, but are not limited thereto.

[0031] In addition to observing the sample under natural light, the sample mounting module 4 of this embodiment further includes a light source unit (not shown in the figure), which provides an additional light source, making the image of the observed sample clearer.

[0032] Finally, the user starts the photographing function of the smart communication device 50 and captures an image by the image capture device 51. At this time, the image capture device 51, the opening O of the fixture 3, and the objective lens unit 1 are all located in the optical path P, so that the image capture device 51 can capture the image of the sample located in the sample observation area 41. In particular, in this embodiment, the user can micro-adjust the distance (within the range of 0.1mm to 3.5mm) between the objective lens unit 1 and the sample by the micro-distance adjustment function provided by the micro-distance adjustment mechanism 2, so that not only can the user observe the sample at the best observation position, but also the user can easily observe different cross sections of the three-dimensional sample, or the surfaces of three-dimensional samples with different thicknesses / heights can be observed.

[0033] The following will use an example to explain the detailed configuration of the micro distance adjustment mechanism of the present invention and also explain the mechanism of micro distance adjustment.

[0034] FIG. 2A is an exploded view of a micro distance adjustment mechanism 2a according to a first embodiment of the present invention, and FIG. 2B is a cross-sectional view of the micro distance adjustment mechanism 2a shown in FIG. 2A.

[0035] As shown in FIG. 2A and FIG. 2B, the micro distance adjustment mechanism 2a of this embodiment includes a first member 21 including a first body 211 having a first perforation H1 on the optical path P and a first screw connection part 212, a second member 22 including a second body 221 having a second perforation H2 on the optical path P and a second screw connection part 222, and a connecting member 23 connected to the first body 211 or the second body 221. The objective lens unit 1 is drilled into the first perforation H1 and the second perforation H2, and for example, the objective lens unit 1 is drilled into the first perforation H1 and fixed by a method of screwing and connecting. The first screw connection part 212 and the second screw connection part 222 are screwed and connected to be rotatable relative to each other, and the first body 211 and the second body 221 have a relative rotation amount during micro distance adjustment, and the connecting member 23 is connected to the first body 211 or the second body 221, so that the relative rotation amount is 360° or less, and the range of the micro distance adjustment is 0.1 mm to 3.5 mm. In this embodiment, the first screw connection part 212 and the second screw connection part 222 each have a screw thread structure, and the first screw connection part 212 and the second screw connection part 222 are screwed and connected to each other by the screw thread structure. Due to the above screw thread structure, when the relative rotation amount between the first body 211 and the second body 221 is less than 360°, the distance of the micro distance adjustment is within one pitch. In other words, the pitch of the screw thread structure is 0.1mm to 3.5mm, and the range of the micro distance adjustment is within 0.1mm to 3.5mm. It should be noted that in this embodiment, the objective lens unit 1 is fixed to the first member 21 (first perforation H1), and the sample in the sample observation area 41 is fixed to the second member 22. Therefore, the distance between the objective lens unit 1 and the sample (within a range of 0.1 mm to 3.5 mm) can be micro-adjusted in synchronization with the micro-distance adjustment of the distance between the first member 21 and the second member 22 by the micro-distance adjustment mechanism 2. This not only makes it possible to observe the sample at the best observation position, but also makes it easy to observe different cross sections of a three-dimensional sample, or to observe the surfaces of three-dimensional samples of different thicknesses / heights.

[0036] In this embodiment, the connecting member 23 is connected to the first body 211, and as shown in FIG. 2A, the connecting member 23 is connected to the first body 211 in the axial direction and is installed outside the first screw connection part 212. Meanwhile, the second body 221 is provided with a ring groove 223, and one end of the connecting member 23 extends into the ring groove 223 (as shown in FIG. 2B). In addition, in this embodiment, the micro distance adjustment mechanism 2 further includes a stopper part 24, which is installed in the rotation path of the connecting member 23. The stopper part 24 is installed in the ring groove 223 to limit the rotation angle of the connecting member 23 in the ring groove 223. That is, this configuration can limit the relative rotation amount between the first body 211 and the second body 221 to 360° or less. In actual operation, the relative rotation between the first body 211 and the second body 221 is 360° or less, so that the range of the micro distance adjustment is within 0.1mm to 3.5mm. Therefore, the distance between the objective lens unit 1 and the sample located in the sample observation area 41 is within the range of 0.1 mm to 3.5 mm that allows micro-distance adjustment.

[0037] In this embodiment, the connecting member 23 is a bolt, and the stopper portion 24 is a protrusion. It should be noted that the connecting member 23 and the stopper portion 24 may have other configurations, for example, the connecting member 23 may be a pin, and is not limited to this in the present invention.

[0038] In addition, the micro distance adjustment mechanism 2 further includes a damping structure 25, which abuts against the connecting member 23. In this embodiment, the damping structure 25 has a rough surface and is installed at the bottom of the ring groove 223, and the lower edge of the connecting member 23 abuts against the damping structure 25 at the bottom of the ring groove 223. By using such a damping structure 25, when the first body 211 and the second body 221 rotate relatively to each other at an appropriate angle, i.e., when they reach a better or best observation position, the relative positions of the first body 211 and the second body 221 can be fixed, so that the relative positions of the image capture device 51, the objective lens unit 1 and the sample located in the sample observation area 41 can be fixed, and the image of the sample can be captured by the image capture device 51 in a stable state to observe the sample.

[0039] In other embodiments, the damper structure 25 may be, but is not limited to, a concave / convex surface, a wavy surface, a jagged surface, a silica gel material, a rubber material, or a combination thereof.

[0040] In addition, in this embodiment, a scale is provided on the periphery of the second member 22 to indicate the relative rotation amount between the first body 211 and the second body 221. The scale may range from 0° to 350°, or may be equally divided into 0 to 9 within 350° (as shown in FIG. 2B). It should be noted that the above is merely an example and does not limit the scope of the present invention.

[0041] Moreover, FIG. 3A is an exploded view of a micro distance adjustment mechanism 2b according to a second embodiment of the present invention, and FIG. 3B is a cross-sectional view of the micro distance adjustment mechanism 2b shown in FIG. 3A.

[0042] Please refer to Figures 3A and 3B. The component configuration and the connection relationship of the micro distance adjustment mechanism 2b of the second embodiment of the present invention are almost the same as those of the above-mentioned micro distance adjustment mechanism 2a, and the difference is that the second body 221b of the second member 22b of the micro distance adjustment structure 2b of this embodiment is not provided with a ring groove, and one end of the connecting member 23 is provided on the outer periphery of the second screw connection part 222b (shown in Figure 3B). In addition, the stopper part 24b of the micro distance adjustment mechanism 2b is provided on the outer periphery of the second screw connection part 222b in a protruding manner and is provided on the rotation path of the connecting member 23, thereby limiting the angle at which the connecting member 23 rotates along the outer periphery of the second screw connection part 222b. That is, this configuration limits the relative rotation amount between the first body 211 and the second body 221b to 360° or less.

[0043] Moreover, FIG. 4A is an exploded view of a micro distance adjustment mechanism 2c according to a third embodiment of the present invention, and FIG. 4B is a cross-sectional view of the micro distance adjustment mechanism 2c shown in FIG. 4A.

[0044] Please refer to Figures 4A and 4B. The component configuration and the connection relationship of the micro distance adjustment mechanism 2c of the third embodiment of the present invention are roughly the same as those of the above-mentioned micro distance adjustment mechanism 2a, with the difference being that the second body 221c of the second member 22c of the micro distance adjustment mechanism 2c of this embodiment does not have a ring groove and a stopper portion, the connection member 23 is connected to the second body 221c in the radial direction, and a stroke space G is formed above the first screw connection portion 212c. 4B, the connecting member 23c of this embodiment is a pin, which penetrates the second body 221c and the second screw connection part 222c in the radial direction, and one end of the connecting member 23c is inserted into the stroke space G. By restricting one end of the connecting member 23c within the stroke space G, when the first screw connection part 212c and the second screw connection part 222c rotate relatively to perform micro distance adjustment, the relative rotation amount between the first body 211c and the second body 221c can be restricted, for example, the relative rotation amount is 360° or less, and the range of the micro distance adjustment can be restricted to 0.1mm to 3.5mm. It should be noted that the maximum value of the relative rotation amount can be restricted to more than 360° according to the configuration of this embodiment, for example, the relative rotation amount can be restricted to 540°, 720°, etc., but is not limited in the present invention.

[0045] In addition, in this embodiment, the micro distance adjustment mechanism 2c includes a damper structure 25c and abuts against the connecting member 23c. In this embodiment, the damper structure 25c has a rough surface and is arranged to go around one side of the first body 211c in the stroke space G, and one end of the connecting member 23c abuts against the damper structure 25c inside the stroke space G. The function and operation of the damper structure 25c relative to the connecting member 23c can be seen in the above embodiment and will not be described again.
