Description

Technical Field

[0001] The present invention relates to an observation platform, and in particular to a microscope observation platform. Background Art

[0002] Optical microscopes and electron microscopes can be used to observe nanoscale samples, and the samples need to be placed on an observation platform for observation. The observation platform must at least include a base and a cover, and the sample is placed in an observation area between the base and the cover for observation. For current observation platforms, the base and cover are mostly assembled by screwing, which is inconvenient to use. Summary of the invention

[0003] The present invention is directed to a microscope observation platform, which is relatively simple to use.

[0004] According to an embodiment of the present invention, a microscope observation stage includes a base, a lower cover, an upper cover and a rotary cover. The base has at least one first positioning portion. The lower cover has at least one second positioning portion and at least one third positioning portion. The lower cover is detachably arranged on the base and is positioned at the first positioning portion by the second positioning portion. The upper cover has at least one fourth positioning portion. The upper cover is detachably arranged on the base so that the lower cover is located between the base and the upper cover, and the upper cover is positioned at the third positioning portion by the fourth positioning portion. An observation area is formed between the upper cover and the lower cover, and the observation area is suitable for carrying samples. The rotary cover is detachably arranged on the base to limit the upper cover and the lower cover to the base, and the rotary cover is suitable for rotating relative to the base and being locked or released by the base.

[0005] In an embodiment of the present invention, the rotary cover is adapted to rotate relative to the base along a rotation axis, and at least one first positioning portion and at least one second positioning portion are positioned with each other to prevent the lower cover from rotating relative to the base along the rotation axis.

[0006] In an embodiment of the present invention, the rotary cover is adapted to rotate relative to the base along the rotation axis, and at least one third positioning portion and at least one fourth positioning portion are positioned with each other to prevent the upper cover from rotating relative to the lower cover along the rotation axis.

[0007] In an embodiment of the present invention, one of the first positioning portion and the at least one second positioning portion is a protrusion, and the other of the at least one first positioning portion and the at least one second positioning portion is a groove.

[0008] In an embodiment according to the present invention, one of the third positioning portion and the at least one fourth positioning portion is a protrusion, and the other of the at least one third positioning portion and the at least one fourth positioning portion is a groove.

[0009] In an embodiment according to the present invention, the lower cover has a first window, the upper cover has a second window, and the observation area is formed between the first window and the second window.

[0010] In an embodiment according to the present invention, the microscope observation stage includes a first sealing ring and a second sealing ring, wherein the first sealing ring is arranged between the base and the lower cover and surrounds the observation area, and the second sealing ring is arranged between the base and the upper cover and surrounds the observation area.

[0011] In an embodiment according to the present invention, the base has a receiving space, and the receiving space is suitable for receiving the lower cover, the upper cover and the rotating cover.

[0012] In an embodiment of the present invention, the inner edge of the accommodating space has an annular groove, and the periphery of the rotary cover has at least one protrusion, and the at least one protrusion is suitable for extending into the annular groove to prevent the rotary cover from being separated from the base.

[0013] In an embodiment of the present invention, the top surface of the base has at least one recess, the at least one recess is connected to the annular groove, and the at least one protrusion is adapted to correspond to the at least one recess as the rotary cover rotates.

[0014] Based on the above, in the microscope observation platform of the present invention, the upper cover and the lower cover are limited on the base by using the rotary cover, and the rotary cover is locked or separated from the base by its own rotation. Accordingly, the base, the upper cover, the lower cover and the rotary cover can be assembled and disassembled by rotating the rotary cover only, without the need for disassembly and assembly by screw locks, so the microscope observation platform is relatively simple to use. In addition, since the base and the lower cover are mutually positioned by the first positioning structure and the second positioning structure, and the lower cover and the upper cover are mutually positioned by the third positioning structure and the fourth positioning structure, it can be avoided that the rotary cover unexpectedly drives the lower cover and / or the upper cover to rotate during the rotation process.

[0022] Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals are used in the drawings and the description to refer to the same or like parts.

[0023] Figure 1 It is a stereoscopic diagram of a microscope observation stage according to an embodiment of the present invention. Figure 2 yes Figure 1 Exploded view of the microscope observation stage. Figure 3 yes Figure 1 A stereoscopic diagram of the local structure of the microscope observation stage. Figure 4 yes Figure 3 Side view of the microscope observation stage. Figures 1 to 4 The microscope observation stage 100 of the present embodiment includes a base 110, a lower cover 120 and an upper cover 130. The lower cover 120 is detachably disposed on the base 110, and the upper cover 130 is detachably disposed on the base 110 so that the lower cover 120 is located between the base 110 and the upper cover 130. An observation area R is formed between the upper cover 130 and the lower cover 120. The observation area R is suitable for carrying samples, and the microscope can observe the samples in the observation area R. The present invention does not limit the appearance of the base 110, except that it can be Figure 1 and Figure 2 The shape shown can also be other shapes to match different types or models of microscopes according to needs.

[0024] The present invention does not limit the observation mode of the sample carried by the observation area R, and it can be a dynamic observation with liquid flowing in the observation area R, or it can be a non-dynamic observation. If it is a dynamic observation, an appropriate flow channel can be added to the microscope observation stage 100 to allow the liquid to flow through the observation area R. The liquid is used, for example, to carry away metabolites of the sample, or as a medium to add a drug required for measurement to the sample.

[0025] In this embodiment, the lower cover 120 has a first window 122, the upper cover 130 has a second window 132, and the microfluidic chamber between the first window 122 and the second window 132 forms an observation area R. Reflection microscope observation can be performed through the second window 132, or transmission microscope observation can be performed through the second window 132 and the first window 122, and the present invention is not limited to this. Specifically, the first window 122 and the second window 132 respectively include a thin film (such as a silicon nitride film), and in terms of observation under an electron microscope, the thin film is transparent to electrons of a specific energy, so that the electron beam of the electron microscope can pass through the first window 122 and the second window 132.

[0026] The microscope observation stage 100 of the present embodiment further includes a rotary cover 140. The rotary cover 140 is detachably disposed on the base 110 to limit the upper cover 130 and the lower cover 120 to the base 110, and the rotary cover 140 can rotate relative to the base 110 along the rotation axis A (indicated at Figure 1 ) is rotated and locked by the base 110 or released by the base 110. Accordingly, the base 110, the upper cover 130, the lower cover 120 and the rotary cover 140 can be assembled and disassembled by rotating the rotary cover 140 only, without the need for screw locking, so the microscope observation stage 100 is relatively easy to use. The method of assembling and disassembling the rotary cover 140 is described in more detail below.

[0027] In this embodiment, the base 110 has a receiving space S (indicated at Figure 2 and Figure 5 ), the accommodation space S is suitable for accommodating the lower cover 120, the upper cover 130 and the rotating cover 140. Figures 2 to 5 As shown, the inner edge of the receiving space S of the base 110 has an annular groove 110a. The periphery of the rotary cover 140 correspondingly has at least one protrusion 142 ( Figure 2 The protrusion 142 is adapted to extend into the annular groove 110a to prevent the rotary cover 140 from being separated from the base 110. As described above, the top surface of the base 110 has at least one notch 110b ( Figure 1 , Figure 3 , Figure 4 and Figure 5 The notches 110b are connected to the annular groove 110a. The bosses 142 of the rotary cover 140 can correspond to the notches 110b respectively as the rotary cover 140 rotates, so that each boss 142 can move away from the annular groove 110a through the corresponding notches 110b, so that the rotary cover 140 can be disassembled.

[0028] Figure 5 yes Figure 1 A three-dimensional view of the base. Figure 6 yes Figure 2 A three-dimensional view of the lower cover. Figure 7 yes Figure 1 Please refer to the three-dimensional diagram of the upper cover. Figure 2 and Figures 5 to 7In this embodiment, the base 110 has at least one first positioning portion 1101 (two are shown), the lower cover 120 has at least one second positioning portion 1201 (two are shown) and at least one third positioning portion 1202 (two are shown), and the upper cover 130 has at least one fourth positioning portion 1301 (two are shown). The lower cover 120 is positioned at the first positioning portion 1101 of the base 110 by its second positioning portion 1201, so that the lower cover 120 is prevented from rotating along the rotation axis A relative to the base 110 through the mutual positioning of the first positioning portion 1101 and the second positioning portion 1201, and the upper cover 130 is positioned at the third positioning portion 1202 of the lower cover 120 by its fourth positioning portion 1301, so that the upper cover 130 is prevented from rotating along the rotation axis A relative to the lower cover 120 through the mutual positioning of the third positioning portion 1202 and the fourth positioning portion 1301. Thereby, the rotating cover 140 can be prevented from unexpectedly driving the lower cover 120 and / or the upper cover 130 to rotate during the rotation process.

[0029] In this embodiment, the first positioning portion 1101 and the third positioning portion 1202 are, for example, convex blocks, and the second positioning portion 1201 and the fourth positioning portion 1301 are correspondingly grooves. In other embodiments, the first positioning portion 1101 and the third positioning portion 1202 may be grooves, and the second positioning portion 1201 and the fourth positioning portion 1301 may be correspondingly convex blocks. The present invention does not limit the specific forms of the positioning portions.

[0030] Please refer to Figures 2 to 4 , the microscope observation stage 100 of the present embodiment further includes a first sealing ring 150 and a second sealing ring 160. The first sealing ring 150 is disposed between the base 110 and the lower cover 120 and surrounds the observation area R, and the second sealing ring 160 is disposed between the base 110 and the upper cover 130 and surrounds the observation area R. The first sealing ring 150 and the second sealing ring 160 are, for example, rubber rings or other elastic sealing materials, which isolate the observation area R from the outside world to facilitate observation. Further, when the rotary cover 140 is rotated and pressed down along the rotation axis A and locked on the base 110, an average pressing force can be generated at the same time, so that the first sealing ring 150 in contact with the base 110 and the lower cover 120 and the second sealing ring 160 in contact with the base 110 and the upper cover 130 produce a sealing effect, which can isolate the outside world from the sample to be tested in the observation area R. In addition, the first sealing ring 150 and the second sealing ring 160 also have the function of buffering the pressing force.

[0031] like Figure 4 As shown, the upper cover 130 is configured to completely cover the lower cover 120, and the outer periphery of the upper cover 130 has an inclined surface 130a to increase the configurable space of the rotating cover 140, thereby effectively reducing the thickness of the overall structure. In other embodiments, the lower cover 120, the upper cover 130 and the rotating cover 140 can be other appropriate shapes, and the present invention is not limited thereto.

[0032] In summary, in the microscope observation platform of the present invention, the upper cover and the lower cover are limited on the base by the use of a rotary cover, and the rotary cover is locked or separated from the base by its own rotation. Accordingly, the base, the upper cover, the lower cover and the rotary cover can be assembled and disassembled by rotating the rotary cover only, without the need for disassembly and assembly by screw locks, so the microscope observation platform is relatively simple to use. In addition, since the base and the lower cover are mutually positioned by the first positioning structure and the second positioning structure, and the lower cover and the upper cover are mutually positioned by the third positioning structure and the fourth positioning structure, it can be prevented that the rotary cover unexpectedly drives the lower cover and / or the upper cover to rotate during the rotation process.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
