Technical Field

[0001] This utility model belongs to the field of optical equipment technology, and in particular relates to an automatic filter switching device. Background Technology

[0002] With the development of scientific research and the upgrading of the photonics industry, the strong demand for precise characterization of material optical properties at the mesoscale and real-time rapid acquisition of sample information will drive the advancement of related detection technologies. Optical devices typically used for optical measurements employ lasers as excitation sources. The laser light enters a microscope module via an excitation optical path, then illuminates the sample surface. The signal light generated by the sample is collected and processed by a collection optical path after passing through the microscope module. In optical devices, the laser light emitted before entering the sample and the signal light generated by the sample before entering the collection device (e.g., a camera or CCD) require filtering. Multiple filters are typically used for switching to adapt to different application scenarios.

[0003] However, existing filter devices cannot freely adjust their height and angle, which limits user operation and cannot be adapted to individual optical testing platforms. Utility Model Content

[0004] To address the problem that existing filter devices cannot freely adjust height and angle, thus limiting user operation and being unsuitable for certain optical testing platforms, this invention provides an automatic filter switching device that enables free adjustment of height and angle.

Therefore, a feature defined with "first," "second," "third," etc., may explicitly or implicitly include one or more of that feature.

[0024] It should be noted that the "and / or" in this article is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Here, A and B can be singular or plural, respectively. Example 1

[0025] Please refer to Figures 1-3 This utility model provides an automatic filter switching device, including a filter assembly 1 and an adjustment assembly 2. The filter assembly 1 includes a controller 11, a driver 12, and a filter wheel 13. One end of the driver 12 is connected to the filter wheel 13, and the other end of the driver 12 is connected to the controller 11. The adjustment assembly 2 is connected to the controller 11. The driver 12 is used to drive the filter wheel 13 to rotate, thereby realizing seamless switching between filter sequences on the filter wheel 13. The controller 11 is equipped with a high-performance STM32 microcontroller chip to achieve precise control of the driver 12 and smooth communication with the host system. The adjustment assembly 2 adjusts the height and angle of the controller 11, thereby driving the driver 12 and the filter wheel 13 to rise, fall, and rotate together.

[0026] Specifically, the adjustment component 2 includes an adjustable support column 21 and a support base 22 with a fixing button 3. One end of the adjustable support column 21 is detachably connected to the controller 11, and the other end of the adjustable support column 21 is movably disposed within the support base 22. The end of the fixing button 3 can abut against and fix the adjustable support column 21. The diameter of the adjustable support column 21 is smaller than the diameter of the support base 22, and the support base 22 is cylindrical. Therefore, when the fixing button 3 does not abut against the adjustable support column 21, the adjustable support column 21 can rise, fall, and rotate within the support base 22; when the fixing button 3 abuts against the adjustable support column 21, the position of the height and angle of the adjustable support column 21 or the controller 11 is fixed.

[0027] Reference Figure 1 The principle that one end of the adjustable support column 21 can be detachably connected to the controller 11 is as follows: the adjustable support column 21 includes an externally protruding thread 211, and the bottom of the controller 11 is provided with a threaded hole 111, and the externally protruding thread 211 is threadedly matched with the threaded hole 111.

[0028] Furthermore, the driver 12 includes a high-performance rotary motor and a precision planetary reducer. The high-performance rotary motor and the precision planetary reducer are integrally formed. Using a high-performance rotary motor and a precision planetary reducer as the driver 12 not only effectively enhances the output torque of the motor and ensures a strong and stable driving force, but also incorporates an encoder. With the help of the encoder's precise position feedback mechanism, it works in conjunction with the controller 11 to achieve ultra-precise positioning adjustment of 0.01°. Moreover, it can quickly process positioning feedback information, achieving instantaneous switching between the positions of the six filters in only 200 milliseconds, significantly accelerating the experimental and testing process and improving work efficiency.

[0029] Furthermore, the controller 11 is provided with a gear knob 4, which is electrically connected to the driver 12, and the working speed of the driver 12 is controlled by the gear knob 4.

[0030] Furthermore, it also includes a connecting shell 5, one end of which is connected to the controller 11, and the driver 12 is installed at the other end of the connecting shell 5. Example 2

[0031] Please refer to Figure 4This utility model provides an automatic filter switching device, including a filter assembly 1 and an adjustment assembly 2. The filter assembly 1 includes a controller 11, a driver 12, and a filter wheel 13. One end of the driver 12 is connected to the filter wheel 13, and the other end of the driver 12 is connected to the controller 11. The adjustment assembly 2 is connected to the controller 11. The driver 12 is used to drive the filter wheel 13 to rotate, thereby realizing seamless switching between filter sequences on the filter wheel 13. The controller 11 is equipped with a high-performance STM32 microcontroller chip to achieve precise control of the driver 12 and smooth communication with the host system. The adjustment assembly 2 adjusts the height and angle of the controller 11, thereby driving the driver 12 and the filter wheel 13 to rise, fall, and rotate together.

[0032] The adjustment assembly 2 includes a sleeve 23 with a fixing button 3 and a base 24 with a rod 241. The controller 11 is fixedly connected to one side of the sleeve 23. The fixing button 3 is movably disposed on the sleeve 23, and the sleeve 23 is movably disposed on the rod 241 of the base 24.

[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
