Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to optical glass detection technical field, concretely is a kind of optical glass detection equipment. BACKGROUND
[0002] With the wide application of optical glass in precision instruments, consumer electronics, such as mobile phone lens, AR / VR lens, and medical equipment, its surface quality directly affects the imaging accuracy and stability of the optical system. Surface defects (such as micron-level scratches, bubbles, stones, etc.) can cause light scattering, energy loss, and even system failure.
[0003] The traditional method of relying on manual microscope observation requires frequent flipping of the lens to detect multiple surfaces, resulting in a detection speed of only 20-30 pieces / hour, and a high miss rate of over 15%. For relatively large optical glass, it is difficult to completely inspect the optical glass, and when observing with a microscope, the optical glass needs to be manually moved to change its position, so that different positions of the optical glass can be observed, and there may be missed positions. Manually moving the optical glass can easily stick fingerprints on the optical glass, affecting observation, and also easily scratching the optical glass, further damaging the optical glass. SUMMARY
[0004] The utility model aims at providing an optical glass detection equipment to solve the problems raised in the background.
[0005] To solve the above technical problems, the utility model provides the following technical scheme: an optical glass detection equipment, comprising:
[0006] a frame;
[0007] a mounting table fixed inside the frame for supporting the optical glass;
[0008] a detection component arranged on the frame for detecting the optical glass;
[0009] a moving component installed in the frame to drive the detection component to move and detect different positions of the optical glass.
[0010] Further, the mounting table has a circular shape at its middle position for supporting the optical glass, and a rubber protective layer is attached to the upper end surface of the mounting table.
[0011] Further, the detection component includes an observer and a light shield, the mounting table is located between the observer and the light shield, and the light shield has a light source at its upper end.
[0012] Furthermore, the moving component includes a cross shaft one and a cross shaft two that slide horizontally and vertically within the frame. The cross shaft one and the cross shaft two are arranged in contact with each other, one above the other. The cross shaft one and the cross shaft two are used to control the movement of the light shield.
[0013] The moving component also includes two sets of cylinders, both of which are fixed to the frame and drive the movement of cross axis one and cross axis two respectively. The observer has a controller inside, and the two sets of cylinders are electrically connected to the controller.
[0014] Furthermore, the outer periphery of the frame is fixed with sliding grooves, and the ends of the first and second cross shafts are fixed with I-beams, which are slidably arranged in their respective sliding grooves.
[0015] Furthermore, both the first and second cross shafts have through-holes at their upper ends. The lower end of the light-shielding plate is fixed with a shaft. The shaft extends downward into the inner groove at the intersection of the first and second cross shafts, and the diameter of the shaft is the same as the width of the inner groove. The lower end of the shaft is threaded with a bolt, and a limiting piece is fixed on the bolt. The limiting piece fits against the second cross shaft at the lower end.
[0016] An external support frame is fixed between the limiting plate and the observer.
[0017] Furthermore, the outer wall of the outer support frame is rectangular, used to drive the observer and the light shield of the detection component to move together.
[0018] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: Compared with traditional detection methods, it achieves 100% coverage of the detection area through programmed path planning, reducing the missed detection rate and ensuring the quality of optical glass. Non-contact detection of optical glass avoids fingerprint contamination and movement, ensuring stable quality of the optical glass during and after detection, preventing damage. Manual movement of optical glass can easily cause impurities to adhere to it, while this detection device can avoid stirring up dust and impurities to a certain extent. Driven by a pneumatic system, it is more shock-resistant than motor-driven systems. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figures 1-6 This utility model provides a technical solution: an optical glass inspection device, comprising:
[0029] Framework 1;
[0030] Mounting platform 3, fixed inside frame 1, is used to support optical glass;
[0031] The detection component 4 is mounted on the frame 1 and is used to detect optical glass.
[0032] The moving part 2 is installed inside the frame 1 and drives the detection part 4 to move to detect different positions of the optical glass.
[0033] Specifically, the mounting platform 3 limits the optical glass, and the moving part 2 drives the detection part 4 to move, thereby realizing the detection of the optical glass.
[0034] The mounting platform 3 has a circular shape in the middle to support the optical glass. The upper surface of the mounting platform 3 is covered with a rubber protective layer to prevent damage to the optical glass.
[0035] The detection component 4 includes an observer 41 and a light shield 42. A mounting stage 3 is located between the observer 41 and the light shield 42. A light source is located on the upper end of the light shield 42. The light source of the light shield 42 provides standard illumination. The observer 41 contains a microscopic imaging system that performs full-area detection on the fixed optical glass surface through a programmed scanning path, avoiding missed detections. The light source of the light shield 42 can achieve brightness gradient compensation, solving the problem of localized overexposure or underexposure caused by the reflection from the curved surface of the optical glass.
[0036] The moving part 2 includes a cross shaft 1 22 and a cross shaft 23 that are slidably intersecting horizontally and vertically within the frame 1. The cross shaft 1 22 and the cross shaft 23 are arranged in an upper and lower contact configuration, and the cross shaft 1 22 and the cross shaft 23 are used to control the movement of the light shield 42.
[0037] The moving part 2 also includes two sets of cylinders 26, both of which are fixed to the frame 1 and drive the movement of cross axis one 22 and cross axis two 23 respectively. The observer 41 has a controller inside, and the two sets of cylinders 26 are electrically connected to the controller.
[0038] Specifically, the controller activates two sets of cylinders 26, which, through air pump control, achieve coordinated movement of cross axis one 22 and cross axis two 23. The two sets of cylinders 26 control the movement along the X and Y axes respectively, forming a motion trajectory in a planar coordinate system. This allows for the inspection of various positions on the optical glass. It enables non-linear scanning paths for the inspection head, such as spiral or serpentine trajectories. For non-rectangular optical glass, it can move in a manner similar to its shape, reducing unnecessary movement paths.
[0039] The outer periphery of frame 1 is fixed with sliding grooves 21, and the ends of cross shaft one 22 and cross shaft two 23 are fixed with I-beams 24, which are slidably arranged in their respective sliding grooves 21.
[0040] Specifically, cross axis 1 22 and cross axis 23 are connected by the sliding engagement of the I-beam 24 within the slide groove 21 to form a cross slide structure. The movement trajectory of the intersection point of the two axes can cover the entire detection area of the mounting platform 3.
[0041] Both the upper ends of the cross shaft 1 22 and the cross shaft 23 are provided with through inner grooves 25. The lower end of the light shield 42 is fixed with a shaft 43. The shaft 43 extends downward into the inner groove 25 at the intersection of the cross shaft 1 22 and the cross shaft 23. The diameter of the shaft 43 is the same as the width of the inner groove 25. The lower end of the shaft 43 is threaded with a bolt 45. A limiting piece 44 is fixed on the bolt 45. The limiting piece 44 fits against the lower end of the cross shaft 23.
[0042] An external support frame 46 is fixed between the limiting plate 44 and the observation device 41.
[0043] Specifically, the shaft 43 is linked with the first cross shaft 22 and the second cross shaft 23 through the inner groove 25. The cooperation of the light shield 42, the shaft 43, the limiting plate 44 and the bolt 45 ensures the stable connection of the detection component 4. The outer support frame 46 ensures the synchronous movement of the observer 41 and the light shield 42.
[0044] The outer support frame 46 has a rectangular outer wall and is used to drive the observer 41 and the light shield 42 of the detection component 4 to move together.
[0045] The working principle of this utility model is as follows: The cylinder 26 is driven by the controller to realize the extension and retraction of the cylinder 26. It should be noted that the air inlet and outlet of the cylinder 26 is controlled by the air pump. The connection between the air pump and the cylinder 26 is existing technology. When the cylinder 26 drives the movement of the first cross shaft 22 and the second cross shaft 23, the position of their intersection can move to most positions inside the frame 1. After the optical glass is placed on the mounting platform 3, the movement of the intersection position of the first cross shaft 22 and the second cross shaft 23 drives the movement of the detection component 4 to detect different positions of the optical glass, avoiding missed detections. At the same time, the position of the optical glass is prevented from moving, thus avoiding damage to the optical glass.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
