Description

Technical Field

[0001] This utility model relates to the field of optical lens blank identification technology, specifically a portable mechanism for light transmission testing of optical lens blanks. Background Technology

[0002] In existing technologies, light transmittance testing is conducted on transparent or translucent materials, such as glass and plastic films. The main purpose of light transmittance testing is to determine the light transmittance of the material. Light transmittance refers to the ratio of the light flux that passes through the material to the incident light flux. This parameter is crucial for the application of optical instruments and building materials (such as window glass).

[0003] Especially for optical components and lenses such as lenses and filters, transmittance testing can help detect their optical uniformity and internal defects. For example, a lens with internal bubbles or impurities will show abnormal light transmittance in local areas. Transmittance testing can detect these problems and ensure the performance of optical components.

[0004] In the existing technology, impurities and internal bubbles are allowed inside the optical lens blank. However, it is difficult to detect them by manual inspection. But if a light source is used to illuminate the blank, it is easy to distinguish whether there are bubbles or impurities inside.

[0005] Existing technologies, such as the "Optical Lens Blank Performance Testing Device" disclosed in the technical solution of patent announcement number CN214373274U, and the "Optical Lens Blank Performance Testing Device" disclosed in patent announcement number CN210347079U, can all perform light transmittance testing on optical lens blanks.

[0006] However, in actual use, the above-mentioned equipment is a very large equipment structure and occupies a lot of space. The blanks of some optical lenses are basically scattered. It would be very troublesome to transport the blanks to the equipment. Moreover, when the blanks of optical lenses are transmitted light, the existing technology mostly uses only one transmission method, such as transmitting light from the top of the blank or transmitting light from the side wall of the blank, which cannot reflect the light transmission level well.

[0007] Therefore, in order to solve the above problems, it is necessary to develop a portable optical lens blank light transmission testing device with a reasonable structure and convenient use. Utility Model Content

[0008] The purpose of this invention is to address the shortcomings of existing technologies by providing a portable mechanism for testing the light transmittance of optical lens blanks; the technical solution is as follows:

[0009] A portable mechanism for light transmittance testing of optical lens blanks includes a column, on the upper end of which a test disk is mounted via a hinge. The test disk is flipped inward with the hinge as the base point and is set perpendicular to the column. When the test disk is flipped outward, it is set perpendicular to the column. Several top test light sources are also mounted on the test disk.

[0010] A semi-circular inner ring plate is installed at the middle of the column, and a semi-circular outer ring plate is installed at one end of the inner ring plate through a hinge. The outer ring plate and the inner ring plate can be spliced ​​together to form a circular ring plate of integral structure. Furthermore, lateral test light sources with uniform spacing are installed on the inner walls of both the inner and outer ring plates.

[0011] Open the outer ring plate and place the optical lens blank into the inner ring plate. Assemble the outer and inner ring plates into a circular ring plate. Flip the test disk at the top end inward so that the top test light source on the test disk is aligned with the top end of the optical lens blank. Perform a light transmission test on the top end of the optical lens blank through the top test light source on the test disk. Perform a light transmission test on the sidewall of the optical lens blank through the lateral test light sources on the inner and outer ring plates.

[0012] Furthermore, the top test light source on the test disk is arranged in a ring array, and at least three circles are provided, with the top test light source evenly distributed on the three circles.

[0013] Furthermore, the inner ring plate and the outer ring plate are at the same height, and the lateral test light sources on the inner walls of the inner and outer ring plates are evenly distributed.

[0014] Furthermore, one side of the inner ring plate and the outer ring plate are installed correspondingly by a hinge; the other side is provided with a locking device, which locks the inner ring plate and the outer ring plate into one piece.

[0015] Furthermore, the column is configured as a telescopic rod structure with adjustable length.

[0016] Furthermore, the height of both the inner and outer ring plates is set to -cm; the inner diameter of the inner and outer ring plates is set according to the size of the optical lens blank to be identified; and both the inner and outer ring plates are made of transparent material.

[0017] Furthermore, both the top test light source and the side test light source are connected to a power supply device, which is connected to a power adjustment device. The power adjustment device adjusts the power of the power supply device to adjust the brightness of the test light source. The power adjustment device is also connected to a feedback device and a data storage device.

[0018] Beneficial effects: This utility model has the following beneficial effects:

[0019] 1) This device is portable and can be carried around. Therefore, it can be used to test optical lens blanks scattered in various places, instead of transporting the optical lens blanks to the equipment for testing. It is very convenient to use and the overall structure is also quite reasonable.

[0020] 2) This device has a column with a test disk with a top test light source at the top and an inner and outer ring plate with a side test light source at the middle of the column. It can complete the test from both the top and the side wall, and the structure is reasonable.

[0021] 3) In this device, the inner ring plate and the outer ring plate are installed correspondingly by hinges, and the inner walls of both ring plates are equipped with lateral test light sources. The size of the inner ring plate and the outer ring plate are set accordingly so that after the optical lens blank is put into the ring plate, there is a gap on the inside. The structure is reasonably set.

[0022] 4) If the length of the optical lens blank is long in this device, the top test light source can be used instead of the top test light source. In this case, simply flip the test disc and stand it up. This will not affect the test. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented under the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a portable mechanism for light transmission testing of optical lens blanks includes a column 1. A test disk 2 is mounted on the upper end of the column 1 via a hinge 3. The test disk 2 is flipped inward with the hinge 3 as the base point and is set perpendicular to the column 1. When the test disk 2 is flipped outward, it is set vertically to the column 1. Several top test light sources 4 are also correspondingly mounted on the test disk 2.

[0031] A semi-circular inner ring plate 5 is installed at the middle position of the column 1, and a semi-circular outer ring plate 6 is installed at one end of the inner ring plate 5 through a hinge 3. The outer ring plate 6 and the inner ring plate 5 can be spliced ​​together to form a circular ring plate of the whole structure. Furthermore, lateral test light sources 7 with uniform spacing are installed on the inner walls of both the inner ring plate 5 and the outer ring plate 6.

[0032] Open the outer ring plate 6 and place the optical lens blank 9 into the inner ring plate 5. Assemble the outer ring plate 6 and the inner ring plate 5 into a circular ring plate. Flip the test disk 2 at the upper end inward so that the top test light source 4 on the test disk 2 is aligned with the upper end of the optical lens blank 9. Perform a light transmission test on the upper end of the optical lens blank 9 through the top test light source 4 on the test disk 2. Perform a light transmission test on the side wall of the optical lens blank 9 through the lateral test light sources 7 on the inner ring plate 5 and the outer ring plate 6.

[0033] The top test light source 4 on the test disk 2 is arranged in a ring array, and at least three circles are provided, with the top test light source 4 evenly distributed on the three circles.

[0034] The inner ring plate 5 and the outer ring plate 6 are at the same height, and the lateral test light sources 7 on the inner walls of the inner ring plate 5 and the outer ring plate 6 are evenly distributed.

[0035] One side of the inner ring plate 5 and the outer ring plate 6 are installed correspondingly by the hinge 3; the other side is provided with a locking device 8, which locks the inner ring plate 5 and the outer ring plate 6 into one piece.

[0036] The column 1 is designed as an adjustable telescopic pole structure.

[0037] The height of both the inner ring plate 5 and the outer ring plate 6 is set to 10-20cm; the inner diameter of the inner ring plate 5 and the outer ring plate 6 is set according to the size of the optical lens blank 9 to be identified; and both the inner ring plate 5 and the outer ring plate 6 are made of transparent material.

[0038] like Figure 4 As shown, the top test light source 4 and the side test light source 7 are both connected to the power supply device 10. The power supply device 10 is connected to the power adjustment device 11, which adjusts the power of the power supply device 10 to adjust the brightness of the test light source. The power adjustment device 11 is also connected to the feedback device 12 and the data storage device 13.

[0039] The technical solution of this device is a portable mechanism designed for light transmission testing of optical lens blanks, such as... Figure 1 As shown, the existing optical lens blanks are usually cylindrical, although there are also irregular shapes, but they are usually cylindrical. When using this device, the outer ring plate is opened, the optical lens blank is placed into the inner ring plate, and then the outer ring plate is locked and fixed by the locking device. There is a certain gap between the inner and outer ring plates and the placed optical lens blank. Specifically, the side walls of the optical lens blank can be illuminated by the lateral test light source on the inner and outer ring plates to observe the light transmittance of the optical lens blank.

[0040] Simultaneously, the upper test disc can be used to irradiate the end of the optical lens blank with light. After the test disc at the top of the column is adjusted to the correct position, it is flipped inwards so that the test disc faces the upper surface of the optical lens blank. The upper surface of the optical lens blank is then tested for light transmission through the top test light source on the test disc. When the top test light source is turned on, the side test light source can be turned off or turned on for assistance.

[0041] And such as Figure 5 As shown, if the length of the optical lens blank is long, the top test light source can be omitted, and only the side test light source can be used for testing. In this case, simply flip the test disk and stand it up; it will not affect the test.

[0042] The above-described specific embodiments are merely preferred embodiments of this utility model and are not intended to limit the implementation of this utility model or the scope of the claims. All equivalent changes and modifications made in accordance with the scope of protection of this utility model patent application should be included within the scope of this utility model patent application.
