Description

Technical Field

[0001] The utility model relates to the field of measurement technology, in particular to an optical measurement device based on ultraviolet light. Background Art

[0002] During the lens processing, in order to ensure the optical performance of the lens, an optical detector is needed to detect the lens to ensure the qualified rate of the product.

[0003] For example, the invention patent with the publication number: CN118583458A discloses an eccentricity measurement device and method for aspherical optical parts, which relates to the field of aspherical eccentricity measurement technology. It includes a bearing plate, on the upper surface of which a base is installed. One side of the base is fixedly connected with a support frame, and on one side of the support frame, a microscope is installed. On the surface of the base corresponding to the position of the microscope, there is a lens, and on the surface of the base corresponding to the position of the lens, there is an adjusting device. The adjusting device includes a positioning component and a rotating component. The positioning component includes a positioning frame, and the bottom end of the positioning frame is fixedly connected with the surface of the base. The present invention solves the problem that when measuring an optical lens with an eccentricity meter, it is usually necessary to fix and limit the optical lens. Since there are many types of optical lenses, and the fixed size of the optical lens on the entire operating table is relatively unified, it is inconvenient to replace and limit various types of optical lenses.

[0004] The invention patent with the announcement number: CN118362293B discloses a lens group center deviation measurement device and method, belonging to the field of optical detection technology, which solves the problems that the existing high-precision autocollimator will reduce the measurement accuracy of the center deviation of the lens group, and because it is necessary to replace the accessory lens within the corresponding detection range to achieve the purpose of detecting the center deviation of the lens group with different radii, the operation is complicated. The measuring head includes a collimating lens group, a first beam splitting prism, a second beam splitting prism, a first detector, a second detector and a light source; a first beam splitting prism is placed above the collimating lens group; on the light-transmitting side of the first beam splitting prism, there is a second detector that can move along the optical axis A1 direction, and on its light-reflecting side, there is a second beam splitting prism; on the light-transmitting side of the second beam splitting prism, there is a light source, and on its light-reflecting side, there is a first detector. The first detector is placed at the focus of the autocollimation optical path, and the light source is placed at the position conjugate to the first detector.

[0005] In the prior art, the measurement of the lens generally measures the size of the lens, such as the thickness, surface finish, etc. After the measurement, only whether the conventional parameters of the lens meet the requirements can be obtained; however, only measuring the conventional parameters of the lens cannot ensure that all lenses meet the requirements, resulting in the need to replace the already installed lens later and causing rework.

At this time, the ultraviolet light emitter component emits ultraviolet light to trigger the fluorescent sheet component. Since the fluorescent sheet component is a standard fluorescent sheet, after the ultraviolet light emitter component is turned off, the triggered ultraviolet light emitter component will emit fluorescence, and the fluorescence is refracted into the second channel through the beam splitter and then reaches the fluorescence detection sensor through the filter. During the detection process, the plano-convex lens is the only variable. Therefore, only according to the structure detected by the fluorescence detection sensor, the detection of the plano-convex lens can be realized, thereby ensuring that the produced plano-convex lenses can meet the requirements and improving the passing rate of the lenses leaving the factory for use.

Such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0034] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0035] Refer to Figures 1 - 3 , this embodiment discloses an optical measurement device based on ultraviolet light, including a housing 101. A first channel 102 and a second channel 103 are arranged in the housing 101. The first channel 102 and the second channel 103 are perpendicular to each other to form a T-shaped channel structure.

[0036] Among them, an ultraviolet light emitter assembly 104 is arranged at the top of the first channel 102, a beam splitter 105 is arranged in the first channel 102, and a filter lens 106 and a fluorescence detection sensor 107 are arranged in the second channel.

[0037] A first installation groove 108 is arranged on the side of the housing 101. The first installation groove 108 is communicated with the first channel 102, and a first carrier bracket 109 is slidably arranged in the first installation groove 108. A stepped groove 110 is formed on the first carrier bracket 109, and a plano-convex lens to be detected is placed in the stepped groove 110. A fluorescence sheet assembly 111 is arranged at the bottom position of the first channel 102.

[0038] In actual use, the present utility model is mainly used to realize the detection of plano-convex lenses, simulate the actual use environment of plano-convex lenses, and accurately measure the performance of plano-convex lenses before leaving the factory, so as to ensure that each plano-convex lens leaving the factory can meet the requirements and avoid rework.

[0039] In actual use, the plano-convex lens to be detected is placed on the first carrier bracket 109, and the first carrier bracket 109 is pushed into the first installation groove 108 to place the plano-convex lens. At this time, the ultraviolet light emitter assembly 104 emits ultraviolet light to trigger the fluorescent sheet assembly 111. Since the fluorescent sheet assembly 111 is a standard fluorescent sheet 115, after the ultraviolet light emitter assembly 104 is turned off, the triggered ultraviolet light emitter assembly 104 will emit fluorescence. The fluorescence is refracted by the beam splitter 105 into the second channel 103 and then reaches the fluorescence detection sensor 107 after passing through the filter 106. During the detection process, the plano-convex lens is the only variable. Therefore, only based on the structure detected by the fluorescence detection sensor 107 can the detection of the plano-convex lens be achieved, thereby ensuring that the produced plano-convex lenses meet the requirements and improving the passing rate of the lenses when leaving the factory for use.

[0040] Among them, the ultraviolet light emitter assembly 104 includes a bracket and an ultraviolet light emitter installed in the bracket. The bracket is detachably connected to the first channel 102.

[0041] It should be noted that in actual use, in addition to using the fluorescence detection sensor 107, a photomultiplier tube can also be used.

[0042] In actual use, the bracket and the first channel 102 are detachably connected by threads, snap fits or interference fits.

[0043] It is more convenient during installation and is also convenient for replacing ultraviolet light emitters with different powers later.

[0044] Among them, a second installation groove 112 is provided on the housing 101. The second installation groove 112 communicates with the first channel 102. The fluorescent sheet assembly 111 is slidably installed in the second installation groove 112; the replacement of the fluorescent sheet assembly 111 can be achieved through the provided second installation groove 112.

[0045] In actual use, the fluorescent sheet assembly 111 includes a second carrier bracket 113. A placement groove 114 is provided on the second carrier bracket 113. The placement groove 114 is used to place the fluorescent sheet 115. In actual use, only the fluorescent sheet 115 needs to be replaced according to the detection requirements.

[0046] Among them, the housing 101 includes a housing A116 and a housing B117. The housing A116 and the housing B117 are connected together by screws. This is convenient for installing components such as the beam splitter 105 and the filter 106. In actual use, a card slot method is used for card installation.

[0047] Further, in actual use, a gasket is provided between the housing A116 and the housing B117 to ensure that there is no light leakage after the housing A116 and the housing B117 are buckled together.

[0048] Among them, a cover plate 118 is provided on the housing 101, and the fluorescence detection sensor 107 extends into the second channel 103 after being installed on the cover plate 118. This facilitates the installation of the fluorescence detection sensor 107.

[0049] In actual use, the fluorescence detection sensor 107 is connected to a display through a control circuit board to facilitate the display of the detection results. The control circuit board can be a control circuit board in the prior art, and the present invention does not involve the improvement of the control circuit board.

[0050] Among them, the first carrier bracket 109 is made of plastic, so as to avoid scratching the plano-convex lens after it contacts the first carrier bracket 109.

[0051] Further, in some preferred embodiments, a slide rail is provided on the side wall of the first installation groove 108, and a slider that is slidably matched with the slide rail is provided on the side surface of the first carrier bracket 109. The first carrier bracket 109 can be made to move more stably by providing the slide rail and the slider.

[0052] Further, a limiting protrusion for limiting the first carrier bracket 109 is provided in the first installation groove 108. The first carrier bracket 109 can be limited by providing the limiting protrusion, so as to avoid pulling out the first carrier bracket 109 and disengaging it from the first installation groove 108, resulting in the detachment of the first carrier bracket 109.

[0053] Although the preferred embodiments of the present invention have been described, those skilled in the art can make additional changes and modifications once they learn the basic creative concepts. Therefore, the appended claims are intended to be construed as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0054] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
