By adopting the technical scheme of the invention, when the lens is placed on the surface original detector and the aperture is detected, the light source is started, and the light of the light source shines on the surface original detector through the light-transmitting area, so that the interference of lens scattering and reflection is reduced, the aperture of the lens is clearly visible, the aperture number of the lens is rapidly read, the misjudgment is prevented, the quality is improved, and the operation efficiency is improved.
Description
Technical Field
The invention relates to the technical field of lens aperture detection, in particular to a lens aperture detection device.
Background
The method for inspecting the aperture of the optical lens generally places the lens or the surface original inspection device on black rough paper, and then pastes the lens and the surface original inspection device together to confirm the aperture, because the light reflection effect is poor, and simultaneously, the interference of scattered light and inverted image of the lens is caused, the color of the aperture is light, the accurate reading is not well confirmed, and the misjudgment and the efficiency are low.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide a lens diaphragm detection device, which can reduce the interference of lens scattering and reflection, make the lens diaphragm clearly visible, quickly read the lens diaphragm number, prevent misjudgment, improve the quality and improve the operation efficiency.
In order to solve the technical problems, the technical scheme of the invention is as follows: a lens aperture detection device comprises a detection box, a light source and a surface detector; the light source set up in the detection case, be equipped with the printing opacity district on the detection case, the face original ware set up in on the printing opacity district.
Further, the light source is a fluorescent lamp.
Further, the light-transmitting area is formed by arranging a light-transmitting plate or a glass sheet on the detection box.
Furthermore, a black leather pad is arranged between the surface detector and the light-transmitting area.
Further, still include the fixed bolster, the light source pass through the fixed bolster set up in the detection case.
By adopting the technical scheme, when the lens is placed on the surface original checking device to detect the aperture, the light source is started, and the light of the light source penetrates through the light-transmitting area to irradiate the surface original checking device, so that the interference of lens scattering and reflection is reduced, the aperture of the lens is clear and visible, the number of the lens apertures is read quickly, misjudgment is prevented, the quality is improved, and the operation efficiency is improved.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
FIG. 1 is a schematic structural diagram of a lens aperture detecting device according to the present invention.
In the figure, 1-detection box, 2-light source, 3-surface detector, 4-light-transmitting area, 5-fixed support and 6-lens.
Detailed Description
The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "thickness", "up-down, front-back, left-right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the elements referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and therefore, should not be taken as limiting the present invention. Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the described features.
In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise. It should be noted that unless expressly stated or limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly and include, for example, fixed or removable connections or integral connections; may be mechanically connected, may be electrically connected or may be in communication with each other; either directly or indirectly through intervening media profiles, either internally or in any combination thereof. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
In one embodiment of the present invention, as shown in fig. 1, there is provided a lens aperture detecting apparatus, characterized in that: comprises a detection box 1, a light source 2 and a surface detector 3; the light source 2 set up in the detection case 1, be equipped with printing opacity district 4 on the detection case 1, the face original ware 3 set up in on the printing opacity district 4. Specifically, when the lens 6 is placed in the original plane detector 3, the light source 2 is turned on, and light of the light source 2 penetrates through the light-transmitting area 4 to irradiate the original plane detector 3, so that the scattering and reflection interference of the lens 6 is reduced, the aperture of the lens 6 is clear and visible, the number of the diaphragm of the lens 6 is rapidly read, misjudgment is prevented, the quality is improved, and the operation efficiency is improved. The light source 2 may be a fluorescent lamp or an LED lamp, etc., and preferably, the light source 2 is a fluorescent lamp. For example, a three-primary-color fluorescent lamp has the advantages of high light efficiency, good color rendering and longer service life. Although the price is about twice as high as that of a halogen powder fluorescent lamp, the energy-saving effect is good and the operation cost is reduced due to high light efficiency; and because the number of the used lamps is reduced, the cost of the lamps and the ballast is saved, and the total initial cost of the lighting system is reduced.
In this embodiment, the light-transmitting area 4 is formed by disposing a light-transmitting plate or a glass sheet on the detection box 1. Of course, in other embodiments, the light-transmitting region 4 may be made of other light-transmitting materials.
In this embodiment, a black leather pad (not shown) is further disposed between the surface detector 3 and the light-transmitting region 4 to enhance the light-transmitting concentration.
In this embodiment, the lens aperture detection device further includes a fixing bracket 5, and the light source 2 is disposed in the detection box 1 through the fixing bracket 5.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, and the scope of protection is still within the scope of the invention.
