Abstract
Description
Technical Field
[0001] This utility model relates to the field of lens testing technology, specifically a testing device for optical lens production. Background Technology
[0002] Optical lenses are lenses made of optical glass. Optical glass can change the direction of light propagation and can change the relative spectral distribution of ultraviolet, visible or infrared light.
[0003] Lasers are used to perform spectrophotometric testing on optical lenses. Lasers are used to accurately measure the transmittance and reflectance of the lens to specific wavelengths of light. In addition, laser spectrophotometers can be used to analyze the optical characteristics of the lens at different wavelengths to ensure that it meets the design requirements.
[0004] In existing technologies, to avoid eye damage during laser inspection of optical lenses, the laser needs to be frequently started and stopped when workers place the lenses for spectroscopic inspection. However, the laser needs time to reach thermal equilibrium upon startup, and frequent starts and stops lead to unstable output power and wavelength, affecting inspection accuracy. Furthermore, prolonged and frequent laser starts and stops can have various negative impacts on the laser itself, the performance of the inspection system, and operational safety. Therefore, those skilled in the art have provided an inspection device for optical lens production to solve the problems mentioned in the background art. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this utility model provides a testing device for optical lens production. This device addresses the issue that, to avoid eye damage during laser testing of optical lenses, frequent starting and stopping of the laser is necessary when workers place the lenses. However, the laser requires time to reach thermal equilibrium upon startup, and frequent starting and stopping leads to unstable output power and wavelength, affecting testing accuracy. Furthermore, prolonged and frequent laser starting and stopping can negatively impact the laser itself, the performance of the testing system, and operational safety.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution: a testing device for optical lens production, comprising a base, a support plate mounted on the upper side of the base, a bracket mounted on the support plate, a circular slot on the lower side of the support plate, a movable groove on the front side of the circular slot, a through hole vertically formed in the movable groove, a laser emitter positioned below the through hole, a laser receiver positioned above the through hole, a sliding groove on the upper side of the support plate, a turntable positioned in the circular slot, a retaining ring mounted on the periphery of the turntable, a lever mounted on one side of the retaining ring, a positioning rod mounted on the upper side of the turntable, a first clamping plate positioned above the turntable, and a second clamping plate positioned on one side of the first clamping plate.
[0009] Preferably, the upper and lower walls of the dial plate are in close contact with the upper and lower inner walls of the movable groove, and the dial plate initially blocks the through hole.
[0010] Preferably, there are two positioning rods, which are eccentrically and symmetrically arranged.
[0011] Preferably, the bottom of the first clamping plate and the second clamping plate are provided with limiting grooves, the top of the first clamping plate and the second clamping plate are installed with limiting strips, the first clamping plate and the second clamping plate are slidably inserted into the corresponding positioning rods through the limiting grooves, and the upper side of the first clamping plate and the second clamping plate are slidably engaged with the slide groove through the corresponding limiting strips.
[0012] Preferably, the turntable is rotatably engaged with a circular slot via a retaining ring. After placing the optical lens between the first and second clamping plates, the lever is turned, and the lever moves within the movable slot, causing the turntable to rotate. The rotation of the turntable causes the first and second clamping plates to retract relative to each other, thereby positioning the optical lens. At this time, the through hole is opened by the movement of the lever, and the laser from the laser emitter can pass through the through hole to detect the optical lens.
[0013] Preferably, the laser emitter is mounted to the base, and the laser receiver is mounted to the bracket, so that the laser light from the laser emitter can be detected by the optical lens through the through hole, and the wavelength is received by the laser receiver.
[0014] (III) Beneficial Effects
[0015] Compared with the prior art, the present invention provides a testing device for optical lens production, which has the following advantages:
[0016] This practical optical lens production testing device consists of a base, support plate, bracket, laser emitter, and laser receiver. In operation, the dial initially blocks the through-hole. After placing the optical lens between the first and second clamping plates, the lever is moved, moving within the movable slot and rotating the turntable. The rotation of the turntable causes the first and second clamping plates to retract relative to each other, thus positioning the optical lens. At this point, the through-hole opens under the movement of the dial, allowing the laser emitted by the laser emitter to pass through and detect the optical lens. The wavelength is received by the laser receiver. This mechanism eliminates the need for frequent laser start-stop operations, avoiding the negative impacts on the laser itself, the testing system performance, and operational safety caused by prolonged and frequent laser start-stop operations. It also prevents workers from being injured by the laser while placing the optical lens. Attached Figure Description

[0024] This utility model provides a technical solution: a testing device for optical lens production. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The system includes a base 1, a support plate 2 mounted on the upper side of the base 1, a bracket 3 mounted on the support plate 2, a circular slot 201 on the lower side of the support plate 2, a movable groove 202 on the front side of the circular slot 201, a through hole 203 vertically opened in the movable groove 202, a laser emitter 101 below the through hole 203, a laser receiver 301 above the through hole 203, a sliding groove 204 on the upper side of the support plate 2, a turntable 4 inside the circular slot 201, a retaining ring 401 mounted on the periphery of the turntable 4, a lever 402 mounted on one side of the retaining ring 401, a positioning rod 403 mounted on the upper side of the turntable 4, a first clamping plate 5 above the turntable 4, and a second clamping plate 51 on one side of the first clamping plate 5.
[0025] Please see Figure 2 , Figure 3 , Figure 4 , Figure 5 The upper and lower walls of the lever 402 are in contact with the upper and lower inner walls of the movable groove 202. In the initial state, the lever 402 blocks the through hole 203. Two positioning rods 403 are provided, which are eccentrically and symmetrically arranged. The bottom of the first clamping plate 5 and the second clamping plate 51 are provided with limit grooves 501, and the top of the first clamping plate 5 and the second clamping plate 51 are installed with limit strips 502. The first clamping plate 5 and the second clamping plate 51 are slidably inserted with the corresponding positioning rods 403 through the limit grooves 501. The upper side of the first clamping plate 5 and the second clamping plate 51 are slidably engaged with the slide groove 204 through the corresponding limit strips 502. The turntable 4 is rotated through the circular slot 201 by the retaining ring 401. After placing the optical lens between the first clamping plate 5 and the second clamping plate 51, the lever is moved. The lever moves in the movable slot 202, causing the turntable 4 to rotate. The rotation of the turntable 4 causes the first clamping plate 5 and the second clamping plate 51 to retract relative to each other, thereby positioning the optical lens. At this time, under the movement of the lever 402, the through hole 203 is opened, and the laser of the laser emitter 101 can pass through the through hole 203 to detect the optical lens. The laser emitter 101 is installed with the base 1, and the laser receiver 301 is installed with the bracket 3. The laser of the laser emitter 101 can pass through the through hole 203 to detect the optical lens, and the wavelength is received by the laser receiver 301.
[0026] This practical testing device for internal optical lens production consists of a base 1, a support plate 2, a bracket 3, a laser emitter 101, and a laser receiver 301. A circular slot 201 is provided in the support plate 2, and a turntable 4 is provided in the circular slot 201. A retaining ring 401 is installed around the turntable 4. The retaining ring 401 is rotatably engaged with the inner wall of the circular slot 201. A lever 402 is installed at one end of the retaining ring 401. The lever 402 is located in a movable groove 202 on one side of the circular slot 201. A through slot is vertically provided in the movable groove 202. The laser emitter 101 is located below the through hole 203, and the laser receiver 301 is located above the through hole 203 and installed with the bracket 3.
[0027] Two eccentric and symmetrically arranged positioning rods 403 are installed on the upper side of the turntable 4. A sliding groove 204 is opened on the upper inner wall of the support plate 2. A first clamping plate 5 and a second clamping plate 51 are provided on the support plate 2. A limiting groove 501 is opened at the bottom of the first clamping plate 5 and the second clamping plate 51. The limiting groove 501 is slidably inserted with the corresponding positioning rod 403. A limiting strip 502 is installed on the top of the first clamping plate 5 and the second clamping plate 51. The limiting strip 502 on the upper side of the first clamping plate 5 and the second clamping plate 51 is slidably engaged with the sliding groove 204 at the corresponding position.
[0028] In use, the device initially blocks the through hole 203 with the dial plate 402. After placing the optical lens between the first clamping plate 5 and the second clamping plate 51, the lever is moved. The lever moves within the movable groove 202, causing the turntable 4 to rotate. The rotation of the turntable 4 causes the first clamping plate 5 and the second clamping plate 51 to retract relative to each other, thereby positioning the optical lens. At this time, with the movement of the dial plate 402, the through hole 203 is opened, and the laser from the laser emitter 101 can pass through the through hole 203 to detect the optical lens. In this mechanism, there is no need to frequently start and stop the laser, avoiding the negative impacts of frequent start and stop of the laser on the laser itself, the performance of the detection system, and operational safety. It also avoids the problem of workers being injured by the laser when placing the optical lens.
