Description

Technical Field

[0001] This invention belongs to the technical field of upright fluorescence microscopes, specifically relating to an intelligent motorized upright six-well fluorescence module. Background Technology

[0002] An upright fluorescence microscope is a modern type of fluorescence microscope. Its key feature is that the excitation light shines upwards from the objective lens onto the sample surface. The same objective lens serves as both an illumination condenser to focus the excitation light source to generate fluorescence in the sample and to collect the generated fluorescence. An upright fluorescence microscope is an organic combination of a fluorescence illumination system and an upright microscope. Its long working distance condenser allows for direct microscopic observation and study of objects in culture dishes. It offers three observation modes: bright-field observation, phase-contrast observation, and fluorescence observation. It is primarily used for fluorescence and phase-contrast observation of living tissues such as cells. It is widely used in biology, medicine, and other fields for microscopic observation and research in tissue culture, in vitro cell culture, plankton, environmental protection, food inspection, food testing, and liquid sediment analysis. An important accessory of a fluorescence microscope is the fluorescence module, which can be adjusted to emit light in the desired wavelength range (e.g., blue, red, green). Currently, changing the fluorescence channel of a fluorescence module in a fluorescence microscope is generally done manually, which can lead to inaccuracies and low efficiency.

Detailed Implementation

[0026] The specific embodiments of the present invention are described below to enable those skilled in the art to understand the present invention. However, it should be understood that the present invention is not limited to the scope of the specific embodiments. For those skilled in the art, various changes are obvious as long as they are within the spirit and scope of the present invention as defined and determined by the appended claims. All inventions utilizing the concept of the present invention are protected.

[0027] The intelligent motorized upright six-well fluorescence module of this embodiment can automatically switch fluorescence channels, effectively solving the problems of inaccurate switching and low efficiency in existing fluorescence modules that rely on manual switching. In this embodiment, the entire fluorescence module can be connected to different microscope optical paths by changing the upper interface 7 and the lower interface 8. (Refer to...) Figure 1 , Figure 8 , Figure 9 and Figure 10 The fluorescence module specifically includes: 1. Outer shell, 2. Excitation block wheel assembly, 3. Light source wheel assembly, 4. Linkage assembly, 5. Concentrating assembly, and 6. Control assembly; In some embodiments, reference Figure 2 , Figure 3 and Figure 4 The excitation block wheel assembly 2, the light source wheel assembly 3, the linkage assembly 4, the focusing assembly 5, and the control assembly 6 are all mounted on the base plate 10 of the housing 1. The excitation block wheel assembly 2 is connected to the light source wheel assembly 3 through the linkage assembly 4. During specific operation, the control assembly 6 controls the linkage assembly 4 to drive the excitation block wheel assembly 2 and the light source wheel assembly 3 to be synchronously aligned, thereby automatically changing the fluorescence channel of the fluorescence module.

[0028] In one specific embodiment, the housing 1 includes a housing 9 and a base plate 10, and the housing 9 is provided with a power switch 44 and a power interface 45.

[0029] In one specific embodiment, the control component 6 includes a main drive board 43 and a control board 42; the control board 42 is mounted on the housing 9, and the main drive board 43 is disposed inside the housing 9. The main drive board is used to control the control motor.

[0030] In some embodiments, the excitation block wheel assembly 2 includes an excitation block turntable 11, at least one excitation block 12, an excitation block shaft 13, an excitation block fixing member 14, a positioning spring 15, a first bearing 16, a first bearing pressure ring 17, a positioning ball 18, and a first bearing bushing 19.

[0031] In one specific embodiment, a first bearing 16 and a first bearing bushing 19 are sequentially fitted into the middle groove of the excitation block fixing member 14. The first bearing 16 is fixed by a first bearing pressure ring 17. The excitation block rotating shaft 13 passes through the first bearing 16, so that the excitation block fixing member 14 makes a circular motion around the excitation block rotating shaft 13, and the excitation block rotating shaft 13 is fixed on the base plate 10.

[0032] In this embodiment, the number of excitation blocks 12 is up to 6. The excitation blocks 12 are connected to the excitation block fixing member 14 via a dovetail joint. Above the excitation block fixing member 14, an excitation block turntable 11 and a positioning spring 15 are coaxially connected in sequence. Six positioning beads 18 are evenly distributed on the excitation block turntable 11, and six grooves corresponding to the positioning beads 18 are distributed on the positioning spring 15. The cooperation between the grooves and the positioning beads 18 enables precise positioning of the excitation blocks 12.

[0033] In actual operation, the excitation block turntable 11 rotates, and the positioning spring 15 is in an upward bent state. When the excitation block turntable 11 rotates to the groove of the positioning ball 18 and the positioning spring 15, the positioning spring 15 resets to the flat state to realize the positioning of the excitation block turntable 11.

[0034] In some embodiments, reference Figure 5 The light source rotating wheel assembly 3 includes a light source turntable 20, a light source module 21, a light source rotating shaft 22, a light source fixing component 23, a positioning sensing plate 24, a second bearing 25, a second bearing pressure ring 26, a focusing component 5, a second bearing bushing 28, a photoelectric sensor 29, a Hall sensor 40, and a magnet 41.

[0035] In one specific embodiment, a second bearing 25 and a second bearing bushing 28 are sequentially fitted into the middle groove of the light source fixing member 23. The second bearing 25 is fixedly connected by a second bearing pressure ring 26. The light source rotating shaft 22 passes through the second bearing 25, so that the light source fixing member 23 moves in a circular motion around the light source rotating shaft 22. The light source rotating shaft 22 is fixedly connected to the base plate 10.

[0036] The number of light source modules 21 is preferably 6. The light source module 21 includes a heat sink 30 and an LED lamp 31. The LED lamp 31 is fixed on the heat sink 30 and fixed on the light source fixing member 23 through the heat sink 30.

[0037] The light source module 21 is connected to the light source fixture 23 by means of a round hole and a set screw, and up to six light source modules 21 of different wavelengths can be installed.

[0038] The light source turntable 20, light source fixing component 23, and positioning sensor plate 24 are coaxially connected from bottom to top to achieve synchronous rotation. The light source turntable 20 is movably mounted on the base plate via bearings. The positioning sensor plate 24 has six evenly distributed equiangular cuts, with an included angle of 60° between adjacent cuts. The photoelectric sensor 29 is fixedly connected to the focusing assembly 5. When the positioning sensor plate 24 rotates, the cuts on it are blocked or switched on in the sensing groove of the photoelectric sensor 29, causing the photoelectric sensor 29 to output low and high levels respectively for positioning. The Hall sensor 40 is mounted on the base plate 10. When the Hall sensor 40 and the magnet 41 on the top surface of the light source turntable 20 are coaxially distributed, the Hall sensor 40 outputs a low level. A circular hole groove is designed on the top surface of the light source turntable 20, and a single magnet 41 is glued to the groove.

[0039] In one specific embodiment, reference is made to Figure 7 The focusing assembly 5 includes a focusing lens group mounting base 32, a first focusing lens 33, a second focusing lens 34, and a third focusing lens 35. The first focusing lens 33, the second focusing lens 34, and the third focusing lens 35 are sequentially fixed on the focusing lens group mounting base 32 and mounted on the base plate 10 via the focusing lens group mounting base 32. A photoelectric sensor 29 is connected to the focusing lens group mounting base 32. In this embodiment, the divergent light source emitted by the LED lamp 31 is coupled to the right side of the lens using a combined lens configuration.

[0040] In some embodiments, reference Figure 6The linkage component 4 includes an excitation block active tooth 36, a light source active tooth 37, a connecting tooth 38, and a control motor 39; Among them, the control motor 39 is controlled by the main drive board 43 in the control component 6 and is mounted on the base plate through the motor mounting seat. The upper and lower output shafts of the control motor are respectively connected to the excitation block active gear 36 and the light source active gear 37. The excitation block active gear 36 is meshed with the gear on the circumferential end face of the excitation block turntable 11. The light source active gear 37 is meshed with the connecting gear 38 and the gear on the circumferential end face of the light source turntable 20 in sequence.

[0041] In one specific embodiment, the ratio of the active gear 36 of the excitation block to the gear of the excitation block turntable 11, and the ratio of the active gear 37 of the light source to the gear on the circumferential end face of the light source turntable 20 are all 1:6, so as to realize that the excitation block turntable 11 and the light source turntable 20 rotate at the same angular velocity, and when they rotate to the designated position, the light source module 21 and the excitation block 12 are synchronously aligned.

[0042] The working principle of this intelligent electric upright six-hole fluorescent module is as follows: When the fluorescent module is powered on, the power switch 44 is pressed to turn on the power. The module performs initialization, and the main drive board 43 drives the control motor 39 to rotate. When the rotation stops after the photoelectric sensor 29 outputs a high level, the Hall sensor 40 returns a low level, indicating a successful reset. The corresponding LED 31 is then lit and the module begins operation. When N positions need to be switched, the rotation continues until the photoelectric sensor 29 outputs N high and low levels, eventually stopping when it reaches a high level. The switch is successful, and the corresponding LED 31 is lit. The control board 42 is designed with six position buttons and two brightness adjustment buttons. A low-level signal is triggered to the main drive board 43 by a light touch, enabling control of the six positions and brightness adjustment of the corresponding LED 31.

[0043] More specifically, the main drive board 43 drives the control motor 39 to rotate, causing the excitation block active tooth 36 and the light source active tooth 37 to rotate, which in turn drives the connecting tooth 38, the excitation block turntable 11, and the light source turntable 20 to rotate. In the excitation block turntable assembly 2, the excitation block turntable 11 rotates, and the positioning spring 15 is in an upward-curved state. When the excitation block turntable 11 rotates to the groove of the positioning ball 18 and the positioning spring 15, the positioning spring 15 self-resets to a flattened state, thus positioning the excitation block turntable 11. In the light source turntable assembly 3, the light source module 21 and the positioning sensing plate 24 rotate. The cut on the positioning sensing plate 24 achieves conduction switching in the sensing groove of the photoelectric sensor 29, causing the photoelectric sensor 29 to output a high level to achieve positioning. When the switching is successful, the LED 31 at the corresponding position is lit, and the divergent light source emitted by the LED 31 is coupled to the right side of the lens through the focusing assembly 5, thereby completing the switching of the fluorescence channel. At this time, when the Hall sensor 40 and the magnet 41 on the top surface of the light source turntable 20 are coaxially distributed, the Hall sensor 40 outputs a low level.

[0044] Although specific embodiments of the invention have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Various modifications and variations that can be made by a person skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of this patent.
