Description

Technical Field

[0001] The utility model relates to the technical field of light guide detection, in particular to equipment for detecting light guide consistency. Background Art

[0002] A light guide is a structural component used to guide light emitted by an LED or other light source from one place to another. Before a light guide is put into use, it needs to undergo a qualification test to ensure that its performance parameters, structural integrity, and reliability meet the design requirements and relevant standards, thereby ensuring the accuracy and stability of information transmission.

[0003] Regarding the detection of the qualification of light guides, the patent document with the authorization announcement number CN207718068U discloses an optical detection light guide device, which opens an annular groove on the top of the microscope's loading plate, movably inserts a first circular tube in the annular groove, heat-seals and adheres the upper end face of the first circular tube to the lower end face of the bearing outer ring, heat-seals and adheres the upper end face of the bearing outer ring to the lower end face of the second circular tube, adheres an LED lamp to the top of the second circular tube, makes the lamp head of the LED lamp face the center of the second circular tube, adheres a button switch to the top of the side wall of the second circular tube, adheres a charging power supply to the outer ring of the bearing, connects the LED lamp, the charging power supply and the button switch in series through a wire, and increases the brightness of the surface of the observed object through the LED lamp for people to observe, and drives the second circular tube and the LED lamp to rotate by rotating the outer ring of the bearing, so that the LED lamp illuminates the observed object from different angles for people to observe.

[0004] It can be seen that the above-mentioned optical detection light guide device only provides a device for manual detection of light guides. The efficiency of manual detection is low, and the observation results of the optical microscope largely rely on the subjective judgment and experience of the observer. Different observers may have different interpretations and judgments on the same phenomenon. The same observer may also be affected by factors such as visual fatigue during observation, resulting in inconsistent observation results, making it impossible to guarantee the qualified rate of light guides.

[0010] A spectrometer, which is mounted on the light guide bracket and is used to measure the brightness and color coordinates of the light guide tail end;

[0011] The light source and the spectrometer are respectively located at two ends of the light guide installation groove.

[0012] The beneficial effect of the equipment for detecting the consistency of light guides provided by the utility model is as follows: by setting a light guide bracket, and opening a light guide installation groove on the top surface of the light guide bracket, respectively setting a light source and a spectrometer at both ends of the light guide installation groove, using the light source to illuminate one end of the light guide, using the spectrometer to measure the brightness and color coordinates of the tail end of the light guide at the other end of the light guide, and comparing the measured brightness and color coordinate information with the brightness and color coordinate information of the qualified part to determine whether the light guide is qualified. Through the above-mentioned settings, the utility model improves the mechanization degree of light guide detection, converts the judgment standard of the qualified light guide from manual experience to brightness and color coordinates, and while improving the detection efficiency, reduces the errors caused by subjective factors such as visual fatigue, and ensures the standardization and consistency of the measurement results.

Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0026] It should be noted that the main concept of the equipment for detecting the consistency of light guides provided by the utility model is: by opening a light guide mounting groove for accommodating the light guide on the top surface of the light guide bracket, and installing a light source and a spectrometer at both ends of the light guide mounting groove respectively, using the light source to illuminate the light guide, using the spectrometer to collect the brightness information and color coordinate information of the tail of the light guide, comparing the collected information with the information of the qualified part to determine whether the light guide is qualified, converting the judgment standard of the qualified light guide from manual experience into brightness and color coordinates, reducing the error caused by subjective factors, ensuring the standardization and consistency of the measurement results, and improving the mechanization degree of light guide detection, improving the detection efficiency, thereby solving the technical problems in the prior art of low efficiency of manual detection of light guides and low consistency of observation results that make it impossible to guarantee the qualified rate of light guides.

[0027] After introducing the basic principle of the utility model, various non-limiting embodiments of the utility model are specifically introduced below.

[0028] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0029] Light guide is an important optical component, which is usually made of high-transmittance materials, has excellent light-guiding performance and mechanical strength, and can guide the propagation of light. The core of light guide is to use the optical properties of materials to transmit and distribute the light emitted by the light source along a predetermined path, thereby achieving effective guidance and distribution of light. It is widely used in technical fields such as lighting, optical communications, medical equipment, and industrial detection.

[0030] Before being put into use, optical waveguides need to undergo qualification testing to ensure that their performance parameters, structural integrity, and reliability meet design requirements and relevant standards, thereby ensuring the accuracy and stability of information transmission. However, existing optical waveguide testing relies too much on the subjective judgment and experience of observers. Different observers may have different interpretations and judgments on the same phenomenon. The same observer may also be affected by factors such as visual fatigue during observation, resulting in inconsistent observation results, making it impossible to guarantee the qualification rate of optical waveguides.

[0031] Based on this, the utility model provides a device for detecting the consistency of light guides to solve the technical problems in the prior art of low efficiency of manual detection of light guides and low consistency of observation results, which leads to the inability to guarantee the qualified rate of light guides.
