Abstract
Description
Technical Field
[0001] This utility model relates to the field of lens testing technology, and more specifically to a device for testing the surface of optical glass lenses. Background Technology
[0002] Optical glass is a key component in optical instruments, and its quality directly affects the performance of the optical system and the imaging quality. As a result, optical glass lens surface inspection devices have emerged. These devices can ensure the optical performance of the lens, such as refractive index and light transmittance, by accurately measuring parameters such as the curvature and flatness of the lens surface.
[0003] Existing optical glass lens surface inspection devices use a fixed light source when inspecting lens samples. This results in relatively limited data acquisition during the inspection process. The fixed nature of the light source means that parameters such as the illumination angle and intensity cannot be flexibly adjusted according to the specific conditions of the lens sample, thus limiting the richness and comprehensiveness of the inspection data.
[0004] Furthermore, the device is prone to slippage during lens fixation. This may be due to insufficient friction between the fixation device and the lens, or an unreasonable design of the fixation structure that fails to ensure the lens remains stable during testing. On the other hand, and more seriously, due to inherent defects and limitations in the materials used in the fixation device, the lens may be subjected to unnecessary impacts due to the material's hardness, elasticity, and other factors when it is fixed in place. In severe cases, such impacts may even cause the lens to shatter, resulting in irreparable damage to the lens itself and potentially affecting the accuracy and reliability of subsequent test results.
[0005] To address the aforementioned problems, this application provides an optical glass lens surface detection device. Utility Model Content
[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an optical glass lens surface detection device to solve the problems existing in the background art.
[0007] This utility model provides the following technical solution: an optical glass lens surface detection device, including a base plate assembly and a movable light source assembly installed on the outside of the base plate assembly, a detection component and a movable component installed on the detection component are mounted on the base plate assembly, and a buffer clamping component is mounted on the movable component;
[0008] Preferably, the base plate assembly includes a bottom circular plate and support feet, wherein four support feet evenly distributed around the circumference are fixedly mounted on the bottom of the bottom circular plate.
[0009] Preferably, the movable light source assembly includes a toothed ring, a locking block, a rotary motor, a gear, a vertical rod, and a spotlight. The toothed ring is fixedly sleeved on the outside of the bottom circular plate. The locking block is slidably locked onto the outer edge of the bottom circular plate and the toothed ring. The rotary motor is fixedly mounted on the locking block. The rotary motor drive shaft is fixedly sleeved on the gear. The gear meshes with the tooth groove on the toothed ring. The vertical rod is fixedly mounted on the locking block. The spotlight is fixedly mounted on the spotlight, with the illumination direction facing the center of the detection assembly. At this time, the rotary motor drive shaft drives the gear. Under the meshing action of the gear and the outer tooth groove of the toothed ring, the locking block is driven to make a circular motion along the outer edge of the bottom circular plate and the toothed ring.
[0010] Preferably, the detection assembly includes a fixing plate, a positioning plate, a photodetector, and a lens sample. The fixing plate is fixedly installed on the bottom circular plate, the positioning plate is fixedly installed on the left and right sides of the top of the fixing plate, the photodetector is fixedly installed in the center of the top of the fixing plate, and the lens sample is placed directly above the photodetector. The detected light passes through the lens sample and is then directed to the photodetector. The photodetector sends the collected data to the detection and analysis equipment to obtain the detection data.
[0011] Preferably, the moving assembly includes a bidirectional threaded rod, a knob, a limiting rod, and a push plate. The bidirectional threaded rod and the limiting rod are both disposed between two positioning plates. The bidirectional threaded rod is located on the front side, and its two ends are respectively rotatably sleeved on the positioning plates disposed on the left and right sides. The limiting rod is fixedly installed between the two positioning plates. The knob is fixedly sleeved on the right extension end of the bidirectional threaded rod. There are two push plates. One end of the push plate is movably sleeved on the limiting rod, and the other end is threadedly sleeved on the bidirectional threaded rod. When the knob is rotated, under the threaded engagement between the bidirectional threaded rod and the push plate, the push plates located on both sides move towards the center along the central axis of the limiting rod.
[0012] Preferably, the buffer gripping assembly includes a limiting sleeve, a buffer spring, a push rod, a push block, double-corner rubber pads, a limiting block, and a limiting groove. The limiting sleeve is symmetrically fixedly installed on the side wall of the limiting rod near the lens sample. The push rod is engaged in the inner cavity of the limiting sleeve. The buffer spring is disposed between the limiting sleeve and the push rod. One side of the push block is fixedly installed on the end of the push rod away from the limiting sleeve, and the other side is fixedly connected to the double-corner rubber pad. A limiting groove is provided on the fixing plate. The limiting block is fixedly installed below the limiting sleeve and is movably engaged in the limiting groove. At this time, during the movement of the buffer gripping assembly, the engagement relationship between the limiting block and the limiting groove limits the overall buffer gripping assembly. When squeezed, the buffer spring between the limiting sleeve and the push rod can provide cushioning.
[0013] The technical effects and advantages of this utility model are as follows:
[0014] When using the device for testing, the rotary motor drives the gears, and the meshing action of the gears with the outer tooth grooves of the gear ring moves the locking block. The spotlights set above shine light onto the lens sample. This design can obtain illumination data of the lens from multiple angles. When fixing the lens sample, turning the knob will cause the push plates on both sides to move towards the center through the threaded meshing action between the bidirectional threaded rod and the push plate to fix the lens sample. The double-corner rubber pads of the buffer spring can effectively cushion and fix the sample, preventing it from breaking due to impact. Attached Figure Description

The vertical rod 205 is fixedly mounted on the locking block 202. The spotlight 206 is fixedly mounted on the spotlight 206. The illumination direction is towards the center of the detection assembly 3. At this time, the drive shaft of the rotary motor 203 drives the gear 204. Under the meshing action of the gear 204 and the outer tooth groove of the gear ring 201, the locking block 202 is driven to make a circular motion along the bottom circular plate 101 and the outer edge of the gear ring 201.
[0023] Reference Figure 1 The detection component 3 includes a fixing plate 301, a positioning plate 302, a photodetector 303, and a lens sample 304. The fixing plate 301 is fixedly installed on the bottom circular plate 101, the positioning plate 302 is fixedly installed on the top left and right sides of the fixing plate 301, the photodetector 303 is fixedly installed in the center of the top of the fixing plate 301, and the lens sample 304 is placed directly above the photodetector 303. The detected light passes through the lens sample 304 and is then directed to the photodetector 303.

[0024] Reference Figure 1The moving component 4 includes a bidirectional threaded rod 401, a knob 402, a limiting rod 403, and a push plate 404. The bidirectional threaded rod 401 and the limiting rod 403 are both arranged between two positioning plates 302. The bidirectional threaded rod 401 is located on the front side and its two ends are respectively rotatably sleeved on the positioning plates 302 located on the left and right sides. The limiting rod 403 is fixedly installed between the two positioning plates 302. The knob 402 is fixedly sleeved on the right extension end of the bidirectional threaded rod 401. There are two push plates 404. One end of the push plate 404 is movably sleeved on the limiting rod 403, and the other end is threadedly sleeved on the bidirectional threaded rod 401. When the knob 402 is rotated, under the threaded engagement between the bidirectional threaded rod 401 and the push plate 404, the push plates 404 located on both sides move towards the center along the central axis of the limiting rod 403.
[0025] Reference Figure 2 and Figure 3 The buffer clamping assembly 5 includes a limiting sleeve 501, a buffer spring 502, a push rod 503, a push block 504, double-corner rubber pads 505, a limiting block 506, and a limiting groove 507. The limiting sleeve 501 is symmetrically and fixedly installed on the side wall of the limiting rod 403 near the lens sample 304.

One side of the push block 504 is fixedly installed on the push rod 503 away from the limiting sleeve 507. One end of 01 is fixedly connected to a double-corner rubber pad 505 on the other side. A limit groove 507 is opened on the fixed plate 301. The limit block 506 is fixedly installed below the limit sleeve 501 and is movably engaged in the limit groove 507. At this time, during the movement of the buffer clamping assembly 5, the overall buffer clamping assembly 5 is limited by the engagement relationship between the limit block 506 and the limit groove 507. When squeezed, the buffer spring 502 between the limit sleeve 501 and the push rod 503 can be used for buffering.
[0026] The working principle of this utility model is as follows: When using the device, the lens sample 304 is placed between the double-corner rubber pads 505. Then, the knob 402 is rotated. Under the threaded engagement between the bidirectional threaded rod 401 and the push plate 404, the push plates 404 on both sides move towards the center along the central axis of the limiting rod 403. Simultaneously, this causes the buffer clamping assembly 5, fixedly mounted on the push plate 404, to press against the center. During the movement of the buffer clamping assembly 5, the overall buffer clamping assembly 5 is limited by the snap-fit relationship between the limiting block 506 and the limiting groove 507. The buffer clamping assembly 5 moves until the double-corner rubber pads 505 are in contact with both sides of the lens sample 304. At this point, the buffer clamping assembly 5 is further pressed, and through the snap-fit relationship between the push rod 503 and the limiting sleeve 501, the buffer clamping assembly 5 is further pressed against the center. The buffer spring 502 placed between the two buffers the push rod 503 and the push block 504 fixedly mounted on the push rod 503. In turn, the double-corner rubber pad 505 buffers and fixes the lens sample 304. During the test, the drive shaft of the rotary motor 203 drives the gear 204. Under the meshing action of the gear 204 and the outer tooth groove of the gear ring 201, the locking block 202 is driven to make a circular motion along the bottom circular plate 101 and the outer edge of the gear ring 201. The spotlight 206 fixedly mounted on the locking block 202 through the vertical rod 205 shines light on the lens sample 304. After passing through the lens sample 304, the light shines on the photosensitive detector 303. The photosensitive detector 303 sends the collected data information to the detection and analysis equipment to obtain the detection data.
