Description

Lens aperture detection device

Technical Field

The utility model relates to a lens light ring detects technical field, in particular to lens light ring 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.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims at providing a lens light ring detection device reduces the interference of lens scattering and reflection, makes the lens light ring clear visible, reads the lens diaphragm number fast, prevents the erroneous judgement, promotes the quality, promotes the operating efficiency.

In order to solve the technical problem, the utility model discloses a technical scheme does: 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.

Detailed Description

The following describes the present invention with reference to the accompanying 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 related to 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 and down, front and back, left and right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed 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 limited 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 meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

As shown in fig. 1, in an embodiment of the present invention, there is provided a lens aperture detecting device, which is 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.
