Abstract
Description
Technical Field
[0001] This utility model belongs to the field of optical path maintenance technology, specifically relating to a variable wavelength light source emitting device for optical path maintenance. Background Technology
[0002] A spectrometer, also known as a spectrometer, is most commonly referred to as a direct-reading spectrometer. It is a device that uses photodetectors such as photomultiplier tubes to measure the intensity of spectral lines at different wavelengths. In essence, after light is emitted from a light source, it is processed by a spectroscopic system to direct the light to a designated location. This spectroscopic system includes many structures, such as an entrance slit, collimating mirror, dispersive elements (prisms / gratings), focusing mirror, and exit slit. During the transport or movement of the spectrometer, these structures can experience angular or positional shifts due to vibrations, leading to deviations in the path of the light during processing, refraction, or reflection, preventing the light from reaching the designated location.
[0003] Therefore, when there is a problem with the path of the light in the spectrometer, it needs to be repaired. However, because the spectrometer is a precision instrument, it cannot be directly disassembled for repair. The problem of light deviation needs to be diagnosed first. However, the internal space of the spectrometer is small and limited. When using ordinary lighting equipment, such as a flashlight, there is not enough space for the lighting equipment to enter and illuminate the repair position. Moreover, the light produced by ordinary lighting equipment is invisible to the naked eye and cannot obtain information about the illumination path and position. Summary of the Invention
[0004] Based on this, this application provides a variable wavelength light source emitting device for optical path maintenance, in order to solve the technical problem in the prior art that ordinary lighting equipment cannot enter the narrow space inside the spectrometer and the emitted light cannot be observed to accurately irradiate the path and position.

[0019] Compared with the prior art, this application has at least the following advantages:
[0020] This application provides a variable wavelength light source emitting device for optical path maintenance. The device involves holding a gripping assembly, turning on the light source, and allowing it to illuminate a dimming assembly. The dimming assembly then drives several light-selecting sections to rotate, aligning one of the light-selecting sections with the light source. The light passing through this section illuminates (selected light) onto a light guide assembly. The inspector can then move the light guide assembly to the inspection position, allowing the emitted light to illuminate that position. The device can select a suitable wavelength of monochromatic light and guide it to the inspection position via the light guide assembly. For example, when using optical fiber, monochromatic light enters from one end of the fiber, and the other end is aligned with the inspection position, allowing the monochromatic light to exit from the other end, thus providing a thin beam of light to illuminate the inspection position. This facilitates the inspector's illumination and confirmation of the optical fiber at the designated location. Attached Figure Description

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0033] Please refer to Figures 1 to 8 In one specific embodiment of this application,
[0034] A variable wavelength light source emitting device for optical path maintenance, comprising:
[0035] A grip component for easy handholding, wherein the grip component is provided with a light source 304;
[0036] A dimming assembly, wherein the dimming assembly is provided with a plurality of light selection parts for selecting light of different wavelengths, and the dimming assembly is disposed on the grip assembly;
[0037] A light guide component is disposed on the grip component and is used to guide and transmit the light selected by the dimming component.
[0038] The grip component can be a handheld handle or a device designed for easy hand gripping. The light selector can be a prism or a filter. The dimming component can be a turntable that rotates several light selectors or a switching device. The light guide component can be an optical fiber or a device capable of guiding light. The light source 304 can be a flashlight or an LED lamp.
[0039] When using it, hold the holding component, turn on the light source 304 so that the light source 304 shines on the dimming component, and then manually drive the dimming component to rotate so that several light selection parts take turns, so that one of the light selection parts (the required light selection part) is aligned with the light source 304, so that the light passing through the light selection part shines on (the selected light) to the light guide component. Then the inspection personnel can move the light guide component to the inspection position so that the outgoing light shines on the inspection position.
[0040] For example, everyday colorless light (light without obvious color characteristics, which is essentially a composite of multiple wavelengths of light) is composed of multiple monochromatic lights, and each monochromatic light has a different wavelength. Taking a filter as an example, several light-selecting parts are different colors, that is to say, each filter has a different color, such as red, orange, yellow, green, blue, indigo, violet, etc.
[0041] When light passes through a filter, light of the same color as the filter can pass through. For example, when yellow light is needed, a yellow filter can be used. When colorless light shines on a yellow filter, the yellow light will pass through the yellow filter, while the rest of the light will be absorbed or reflected, thus allowing the yellow monochromatic light to be selected through the yellow filter.
[0042] In the above way, a suitable wavelength of monochromatic light can be selected as needed, and the monochromatic light can be guided to the detection position through a light guide component. For example, when using an optical fiber, the monochromatic light is shone into one end of the optical fiber, and the other end of the optical fiber is aligned with the detection position so that the monochromatic light is emitted from the other end of the optical fiber, thereby providing a thin beam of light to illuminate the detection position, which makes it easier for the detection personnel to irradiate and confirm the designated position with the optical fiber.
[0043] In order to facilitate the flexible switching of different light selection parts to the position of the light source 304, in this application, the dimming component can rotate along a virtual axis, and the dimming component can drive several light selection parts to align with the light source 304 on the holding component in sequence, and the light selection parts aligned with the light source 304 are aligned with the light guide component.
[0044] When in use, the dimming component can be rotated along a virtual axis, causing several light-selecting parts on the dimming component to rotate along the virtual axis. Different light-selecting parts can be rotated to the position aligned with the light source 304, and the light selected by the light-selecting parts can be directed into the light guide component, enabling flexible adjustment and rotation.
[0045] Specifically, an embodiment is provided for the light selection unit in the above process:
[0046] The light selection unit includes a sleeve 103, and a convex lens 104 is disposed inside the sleeve 103. Several sleeves 103 are disposed in the light-adjusting assembly, and several convex lenses 104 are of different colors.
[0047] When in use, one of the convex lenses 104 is aligned with the light source 304, so that the light emitted from the light source 304 shines on the convex lens 104. This allows the light corresponding to the color of the convex lens 104 to pass through the convex lens 104, and the convex lens 104 can focus the passed light to a point, thereby reducing the degree of light dispersion.
[0048] By using the above method, after selecting monochromatic light, it is possible to focus the monochromatic light to a single point. One end of the light guide component can be positioned at this point, so that all the monochromatic light can enter the light guide component after focusing. This allows as much light as possible to be gathered into the light guide component after selecting the monochromatic light, thereby enabling the light emitted from the other end of the light guide component to provide better brightness.
[0049] Specifically, an embodiment of the dimming component in the above process is provided:
[0050] The dimming assembly includes a central shaft 101 connected to the grip assembly, and a turntable 102 that rotates along the axis of the central shaft 101. The turntable 102 has a plurality of through holes 109 distributed circumferentially along the axis of the central shaft 101, and a plurality of sleeves 103 are respectively embedded in the plurality of through holes 109.
[0051] When in use, the central shaft 101 is mounted on the grip assembly and kept stationary. Then, the turntable 102 can be rotated so that the turntable 102 rotates along the axis of the central shaft 101. When the turntable 102 rotates, the sleeves 103 embedded in the through holes 109 on the turntable 102 will also rotate along the axis of the central shaft 101.
[0052] In the above manner, the conversion of several sleeves 103 can be realized, and the sleeves 103 and through holes 109 can be interlocked to achieve disassembly, so that the convex lens 104 in the sleeve 103 can be replaced when it is damaged or cannot meet the usage requirements.
[0053] Specifically, an embodiment is provided for the positioning of sleeve 103 in the above process:
[0054] One end of the central shaft 101 is formed with an installation sleeve 106, and a sliding sleeve 107 is provided on the installation sleeve 106. A locking pin 108 slides inside the sliding sleeve 107, and a spring is provided at the inner end of the locking pin 108. The end face of the turntable 102 is provided with a plurality of locking holes 105 along the axis of the central shaft 101, and the plurality of locking holes 105 correspond one-to-one with a plurality of sleeves 103. The locking pin 108 can be locked into any one of the locking holes 105.
[0055] The mounting sleeve 106 is connected to the grip assembly. Under normal conditions, the spring pushes the locking pin 108 out of the sliding sleeve 107, so the outer end of the locking pin 108 is always in contact with the turntable 102 and enters one of the locking holes 105. When the turntable 102 is rotated, the outer end of the locking pin 108 has a spherical structure, which can be pushed back into the sliding sleeve 107 by the inner wall edge of the locking hole 105 and squeeze the spring, so that the spring stores force. When the other locking hole 105 is rotated to align with the locking pin 108, the spring pushes the locking pin 108 out and locks into the locking hole 105, thereby fixing the position of the turntable 102 after any sleeve 103 is aligned with the light source 304, thus limiting the turntable 102. If the locking pin 108 gets stuck in the locking hole 105 and causes the turntable 102 to be unable to rotate, the locking pin 108 can be pushed back into the sliding sleeve 107 by finger, and then the turntable 102 can be rotated again.
[0056] In this way, when changing different sleeves 103, the sleeve 103 can be positioned after being aligned with the light source 304, so that the state of the sleeve 103 remains stable. The rotation of the turntable 102 can only be achieved when the inspector rotates the turntable 102 again.
[0057] Specifically, an embodiment of the gripping component in the above process is provided:
[0058] The grip assembly includes a handle 301, a truss 312 fixed to the front end of the handle 301, an installation beam 306 provided on one side of the truss 312, an installation sleeve 106 that can be fitted onto the installation beam 306, and a pressure sleeve 307 that presses against the installation sleeve 106 on the installation beam 306.
[0059] Install the mounting sleeve 106 onto the mounting beam 306, and from... Figures 5 to 8As can be seen, both the mounting sleeve 106 and the mounting beam 306 are rectangular. Therefore, when the mounting sleeve 106 is fitted onto the mounting beam 306, it will not rotate but will remain straight. At this time, the central shaft 101 remains horizontal. Then, the pressure sleeve 307 is fitted onto the mounting beam 306 and pushed to press the pressure sleeve 307 onto the mounting sleeve 106, preventing the mounting sleeve 106 from sliding off the mounting beam 306, thus completing the limiting. Maintenance personnel can use the entire device by holding the handle 301. The pressure sleeve 307 can be a rubber ring, which is interference-fitted with the mounting beam 306. At this time, the pressure sleeve 307 and the mounting beam 306 will not slide relative to each other, so the mounting sleeve 106 can be installed in place, preventing the mounting sleeve 106 from sliding on the mounting beam 306 and improving the installation accuracy. When disassembling, the pressure sleeve 307 is pulled outward by fingers, so that the pressure sleeve 307 no longer restricts the mounting sleeve 106, and the mounting sleeve 106 can be slid off the mounting beam 306.
[0060] The above method not only facilitates operation by maintenance personnel, but also enables rapid assembly and disassembly between the holding component and the dimming component.
[0061] Furthermore, to improve the stability of the central shaft 101 and prevent it from bending when it is mounted on the mounting beam 306 solely by the mounting sleeve 106 without support at the other end, therefore...
[0062] The other end of the central shaft 101 is formed with a slot 110, which can be embedded in the other side of the truss 312.
[0063] In other words, when installing the central shaft 101, the mounting sleeve 106 fixed on the central shaft 101 is placed on the mounting beam 306, and the slot 110 at the other end of the central shaft 101 is embedded in the other side of the truss 312. This achieves the installation and limiting of both ends of the central shaft 101, thereby supporting both ends of the central shaft 101, making the central shaft 101 more stable and preventing bending.
[0064] Furthermore, an embodiment of the gripping component in the above process is provided:
[0065] The grip assembly also includes a battery 303 disposed on the handle 301 for providing power to the light source 304. A switch 302 for controlling the opening and closing of the light source 304 is disposed inside the handle 301. Several sleeves 103 can be aligned with the light source 304 in sequence.
[0066] The maintenance personnel hold handle 301 and can press switch 302 with their fingers. When switch 302 is closed, the circuit is connected, and the battery 303 supplies power to the light source 304, causing the light source 304 to emit light. This allows the maintenance personnel to hold and control the light source 304 with one hand.
[0067] Specifically, an embodiment of the light guide component in the above process is provided:
[0068] The light guide assembly includes an optical fiber 310, which is clamped to a clip 308 on a truss 312. Several sleeves 103 can be aligned sequentially with the inner end of the optical fiber 310, and the sleeves 103 aligned with the optical fiber 310 are also aligned with the light source 304.
[0069] By clamping the optical fiber 310 onto the clip 308 and aligning the end of the optical fiber 310 with the sleeve 103, light passing through the sleeve 103 can enter the optical fiber 310 and then exit from the other end of the optical fiber 310. By moving the optical fiber 310, maintenance personnel can make the light emitted from the optical fiber 310 illuminate the maintenance position.
[0070] Furthermore, in order to reduce the impact of dust and dirt on the turntable 102 and sleeve 103 when exposed to the outside world, a protective cover is provided in this application. The protective cover includes a housing 201 and a cover 202 that can be fastened to the housing 201. The housing 201 and the cover 202 are respectively provided with a light inlet 203 and a light outlet 204.
[0071] The housing 201 is fitted onto the turntable 102 and fixed to the central shaft 101. Then, the cover 202 is fastened onto the housing 201, enclosing the turntable 102 within it, thus reducing the exposed area of the turntable 102. At the same time, the light inlet 203 is aligned with the light source 304, and the position of the light outlet 204 allows the light passing through the sleeve 103 to be emitted. That is, when the turntable 102 moves a certain sleeve 103 to align with the light source 304, the sleeve 103 is also aligned with the light inlet 203, and the other end of the sleeve 103 is aligned with the light outlet 204. This allows the end of the optical fiber 310 to be aligned with the light outlet 204, achieving the effect of directing the monochromatic light selected by the convex lens 104 into the optical fiber 310.
[0072] In addition, the end of the optical fiber 310 is fixed with an interface 309, which can be connected to the light output port 204 through the interface 309, so that the alignment state between the optical fiber 310 and the light output port 204 is kept stable, avoiding misalignment and ensuring that the selected monochromatic light can enter.
[0073] Meanwhile, the lower end of the truss 312 has a rotating roller 311 for winding and coiling the optical fiber 310. The optical fiber 310 can be wound on the roller 311 to prevent it from falling out randomly. This allows the optical fiber 310 to be coiled up, reducing the space occupied and making it easy to carry.
[0074] Here is an example of a completed process as described above:
[0075] First, several convex lenses 104 are of different colors. Then, the mounting sleeve 106 is placed on the mounting beam 306, and the pressure sleeve 307 is pushed onto the mounting sleeve 106. At the same time, the slot 110 at the other end of the central shaft 101 is embedded in the other side of the truss 312. Then, holding the handle 301, the optical fiber 310 wound on the roller 311 is unwound so that the end of the optical fiber 310 is aligned with the position to be inspected. Then, the switch 302 is pressed, so that the light source 304 emits light that shines on the light inlet 203. At this time, the light will enter one of the sleeves 103. At this time, the convex lens in the sleeve 103... The monochromatic light filtered by mirror 104 will pass through the light outlet 204 into the optical fiber 310 and be emitted from the other end of the optical fiber 310. If the emitted light is not the desired monochromatic light, the turntable 102 can be rotated with the other hand to make the turntable 102 drive the other sleeve 103 to be aligned with the light inlet 203. The monochromatic light emitted from the other end of the optical fiber 310 will be continuously observed until the monochromatic light is the desired one. Finally, the other end of the optical fiber 310 can be moved as needed to bring the other end of the optical fiber 310 into the narrow space of the spectrometer to provide illumination for the location that needs to be inspected.
[0076] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
