Description

Technical Field

[0001] The present invention relates to the technical field of optical lens detection, in particular to a light transmission detection device for an optical glass lens. Background Art

[0002] Optical glass lens light transmittance testing devices are used to measure the light transmittance of optical glass lenses. With the widespread use of optical glass in photography, microscopes, eyeglasses, and other optical instruments, light transmittance, as a key quality indicator, has become an integral part of the testing process. Light transmittance testing devices illuminate the lens with a light source and measure the intensity of the light passing through, thereby assessing the lens's transparency and light transmittance. To ensure the quality of optical products, these testing devices must provide high precision, stability, and adaptability to handle optical lenses of varying thicknesses, materials, and sizes.

[0003] According to the technical solution of patent document CN202321754027.0, the optical glass lens transmittance detection device has the following technical defects in its design: 1. In this patent, the installation process of the lens requires the driving component to drive the sliding component to open the limit frame so that the lens can be placed in. This process requires multiple operating steps, among which the adjustment of the sliding component and the opening of the limit frame both rely on the cooperation of the driving component, which increases the complexity of the operation, especially when the lens needs to be replaced frequently, the installation and disassembly process becomes inefficient; 2. Although a sunshade is used in the device to avoid interference from external light sources, the sunshade does not completely cover the entire detection area, resulting in some areas still being affected by external light sources. When the ambient light is unstable or the lighting conditions are more complex, the influence of the external light source cannot be completely eliminated, which may lead to inaccurate detection results, thereby affecting the accurate measurement of transmittance.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0031] Example

[0032] Reference Figures 1 to 7, which is the first embodiment of the present invention, provides an optical glass lens transmittance detection device, including a detection mechanism 100 and a clamping mechanism 200. The detection mechanism 100 ensures accurate measurement of the light transmittance of the optical glass lens and effectively isolates interference from external light sources through a detection system consisting of a fixing table 101, a positioning seat 102, a light-shielding tube 103, an irradiation lamp 104 and an imaging plate 105; the clamping mechanism 200 stably fixes the lens to be tested through components such as a clamping ring 201 and a trapezoidal block 203, and provides convenient clamping and unclamping functions during the lens installation and removal process.

[0033] Specifically, the positioning seat 102 is movably installed at the center of the top of the fixed platform 101. A positioning groove 101a is provided on the upper surface of the fixed platform 101 and directly below the positioning seat 102. The bottom end of the positioning groove 101a is connected to the extrusion chamber 101b. The bottom end of the positioning seat 102 is fixedly connected to the square extrusion plate 108 through the connecting plate 107. The bottom end of the square extrusion plate 108 is fixedly connected to the first spring 109, and the bottom end of the first spring 109 is fixedly connected to the inner bottom wall of the extrusion chamber 101b, thereby playing the role of limiting support for the square extrusion plate 108, the connecting plate 107 and the positioning seat 102. At the same time, the positioning seat 102 can realize the function of upward and downward extension above the fixed platform 101, and the setting of the positioning groove 101a provides sufficient space for the positioning seat 102 to move downward.

[0034] The light-shielding tube 103 is provided with two parts, one part is fixedly mounted on the front end of the fixed platform 101, and the other part is fixedly mounted on the rear end of the fixed platform 101. The irradiation lamp 104 is mounted on the rear wall of the rear end fixed platform 101, and the imaging plate 105 is mounted on the front side of the front end light-shielding tube 103. A light-shielding cover 106 is provided between the two light-shielding tubes 103. The light-shielding cover 106 is slidably provided above the fixed platform 101, so that it can be conveniently opened or closed as needed, so as to effectively block the interference of external light sources and ensure the accuracy of light transmission detection.

[0035] In addition, the clamping mechanism 200 includes clamping rings 201 symmetrically arranged at the front and rear ends of the positioning seat 102, the bottom ends of the two clamping rings 201 are fixedly connected to the movable plates 202, the opposite surfaces of the two movable plates 202 are fixedly installed with trapezoidal blocks 203, the tops of the two trapezoidal blocks 203 are fixedly installed with stop blocks 204, and the opposite surfaces of the two stop blocks 204 are abutted against the front and rear ends of the square extrusion plate 108, the opposite back surfaces of the bottom ends of the two clamping rings 201 are fixedly connected to push plates 205, the opposite back surfaces of the two push plates 205 are fixedly connected to second springs 206, and the two second springs 206 are in a compressed state.

[0036] like Figure 2 、 Figure 5 and Figure 6As shown, the second spring 206 is in a compressed state at this time, and the lens to be tested has not yet been placed on the positioning seat 102. The two clamping rings 201 are in a state away from the positioning seat 102, and the square extrusion plate 108 at the bottom of the positioning seat 102 is against the baffles 204 on both sides, so that the elastic force of the second spring 206 cannot push the clamping ring 201 to move toward the positioning seat 102 through the push plate 205. When it is necessary to test the optical glass lens, the staff only needs to place the lens to be tested on the positioning seat 102 and press downward. The positioning seat 102 can drive the square extrusion plate 108 to move vertically downward through the connecting plate 107. The square extrusion plate 108 can compress the first spring 109, and in the process of the square extrusion plate 108 moving downward, it can squeeze the two trapezoidal blocks 203 at the bottom to move toward its outside. Subsequently, when the bottom surface of the positioning seat 102 When the bottom wall of the positioning groove 101a is in contact with the square extrusion plate 108, the square extrusion plate 108 can be completely moved to the bottom of the two trapezoidal blocks 203. After there is no obstruction from the outer wall of the square extrusion plate 108, the second spring 206 can push the clamping ring 201 to move toward the positioning seat 102 through the push plate 205. The clamping ring 201 can drive the trapezoidal block 203 and the baffle 204 to move into the extrusion cavity 101b through the movable plate 202 at the bottom. When the opposite surfaces of the two clamping rings 201 are in contact with the lens surface, the lens to be tested can be limited and fixed on the positioning seat 102, providing the necessary conditions for subsequent testing. At the same time, the bottom surface of the trapezoidal block 203 can resist the square extrusion plate 108 at the bottom, so that the rebound force of the first spring 109 will not cause the connecting plate 107 and the positioning seat 102 to lift upward, thereby ensuring the stable state of the lens to be tested.

[0037] Furthermore, a first through hole 201a is provided at the center of the two clamping rings 201. The function of the first through hole 201a is to ensure that the light emitted by the irradiation lamp 104 can smoothly penetrate and illuminate the lens to be tested, thereby realizing accurate measurement of the light transmittance of the lens; and the opposite surfaces of the two clamping rings 201 are fixedly installed with buffer pads 207. The interior of the buffer pads 207 is filled with sponge, which plays a buffering and protective role to prevent the lens from being damaged during the clamping process, and at the same time ensure that the lens can be evenly stressed when clamping, thereby avoiding unnecessary pressure and deformation on the lens surface and ensuring the integrity of the lens.

[0038] A second through-hole 103b is defined at the front end of the front light-shielding tube 103. This second through-hole 103b provides a passage for light. Together with the first through-hole 201a and the imaging surface of the imaging plate 105, this ensures that light can pass smoothly through the lens and form an accurate image on the imaging plate. The light emitted by the illumination lamp 104 is aligned with the first through-hole 201a, the second through-hole 103b, and the imaging surface of the imaging plate 105. This ensures that the illumination light is aligned with the imaging process, further enhancing the accuracy of the light transmission detection process.

[0039] After the lens to be inspected is clamped and secured, light from lamp 104 illuminates the lens. The light passes through the lens, passes through second through-hole 103b and first through-hole 201a, and ultimately reaches imaging plate 105. Imaging plate 105 receives the light and transmits it to the inspection system, which analyzes the lens's light transmittance and determines whether it meets predetermined standards. During this process, the lens remains in a stable position, secured by clamping ring 201 and cushioning pad 207. This prevents detection errors caused by lens displacement or deformation, thereby ensuring the accuracy and stability of light transmission testing.

[0040] Furthermore, the front and rear ends of the upper side of the extrusion chamber 101b are connected to the first telescopic groove 101c, and the two sets of movable plates 202, trapezoidal blocks 203 and stop blocks 204 are respectively slidably connected in the two first telescopic grooves 101c to ensure the stable operation of the clamping mechanism. The function of the first telescopic groove 101c is to provide a sliding track for the movable plate 202, trapezoidal block 203 and stop block 204, so that these components can be moved precisely in the extrusion chamber 101b.

[0041] Second telescopic slots 101d are symmetrically positioned within the fixed platform 101, located on either side of the two first telescopic slots 101c. These slots provide additional space and a sliding path, facilitating precise control of the push plate 205 and the second spring 206. Limiting rods 208 are fixedly mounted within each of the second telescopic slots 101d. These rods limit the range of movement of the push plate 205 and the second spring 206, preventing excessive movement that could cause system loss of control. The bottom end of the push plate 205 and the second spring 206 are both mounted on the limiting rods 208. The elastic force of the second springs 206 propels the push plate 205, thereby driving the clamping ring 201 toward the lens, clamping and securing the lens to be inspected. The other end of the second spring 206 is fixedly connected to the inner wall of the second telescopic slot 101d, providing sufficient resilience to allow the push plate 205 to return to its initial position after clamping the lens, thus allowing for subsequent lens replacement or inspection.

[0042] Furthermore, the right ends of both first telescopic slots 101c are connected to through slots 101e. Through slots 101e provide a sliding channel for a toggle rod 209, ensuring smooth horizontal movement between the first telescopic slots 101c and the fixed platform 101. A toggle rod 209 is fixedly connected to the right side of each of the two stoppers 204. Through its connection with the through slots 101e, the toggle rod 209 transmits the driving force of movement to the stoppers 204, further driving components of the clamping mechanism, such as the trapezoidal block 203, the movable plate 202, and the clamping ring 201, to release the lens to be inspected. The right ends of the two toggle rods 209 extend through the two through slots 101e and to the exterior of the fixed platform 101. These rods can be controlled by an external reset assembly 210, providing the necessary guidance and force transmission for the reset operation.

[0043] A reset assembly 210 is provided on the exterior of the fixed platform 101 and between the two toggle rods 209. The reset assembly 210 is configured to restore all components to their initial positions, ensuring that after each lens inspection, the device automatically resets and is ready for the next inspection. The reset assembly 210 includes fixed rods 210a fixedly mounted on the front and rear sides of the right end of the fixed platform 101. The fixed rods 210a provide support and stability for the reset assembly, ensuring that each component maintains a precise motion trajectory during the reset process. A third spring 210b is sleeved on the outer surfaces of both fixed rods 210a. The third spring 210b provides elastic force for the reset operation. When the push plate 210c is pressed, the third spring 210b provides sufficient reaction force to ensure a smooth and stable reset process. One end of the two third springs 210b is fixedly connected to the outer wall of the fixed platform 101, and the other end is fixedly connected to the pressing plate 210c. A trapezoidal squeezing plate 210d is fixedly installed on the left side of the pressing plate 210c. The trapezoidal squeezing plate 210d cooperates with the toggle rod 209 through the inclined surface, so that the sliding of the pressing plate 210c can accurately drive the toggle rod 209 to move horizontally, thereby completing the resetting of the clamping ring 201 and the lens.

[0044] It is worth noting that when the lens to be tested is limited and fixed between the two clamping rings 201, the two toggle rods 209 are close to the trapezoidal extrusion plate 210d. Therefore, after the lens inspection is completed, the staff presses the pressing plate 210c inwardly, and the pressing plate 210c can drive the trapezoidal extrusion plate 210d to move toward the fixed platform 101. Moreover, since the two inclined surfaces of the trapezoidal extrusion plate 210d are respectively facing the two toggle rods 209, the trapezoidal extrusion plate 210d can, during the movement, be guided by the inclined surfaces to make the two toggle rods 209 move horizontally in opposite directions. The two toggle rods 209 can drive the two trapezoidal blocks 203 to move into the first telescopic groove through the two baffles 204. The two trapezoidal blocks 203 can drive the two clamping rings 201 to move horizontally in opposite directions through the two moving plates 202, thereby releasing the clamping and fixing of the lens. The staff can smoothly remove the lens after the inspection is completed, and during the movement of the clamping ring 201, the pushing plate 20 5 forms an extrusion on the second spring 206. At the same time, when the two trapezoidal blocks 203 are completely moved into the first telescopic groove 101c, without the obstruction of the bottom surfaces of the two trapezoidal blocks 203, the square extrusion plate 108 can be lifted upward under the rebound force of the first spring 109. The square extrusion plate 108 can drive the positioning seat 102 to rebound to the initial position through the connecting plate 107, providing the necessary conditions for subsequent use. At this time, the staff releases the pressing plate 210c and Under the action of the rebound force of the three springs 210b, the pressing plate 210c and the trapezoidal extrusion plate 210d can be rebounded to the initial position. After the extrusion force of the trapezoidal extrusion plate 210d is gone, the elastic force of the second spring 206 can drive the push plate 205, the clamping ring 201, the moving plate 202, the trapezoidal block 203 and the baffle 204 to move into the telescopic groove again. When the inner wall of the baffle 204 abuts against the square extrusion plate 108, it can no longer move, and finally reaches the initial unclamped state (such as Figures 2 to 6 shown).

[0045] Preferably, a receiving groove 103a is provided on the inner side of the rear end light shielding tube 103. The function of the receiving groove 103a is to provide a sliding track for the limiting ring 110, ensuring that the limiting ring 110 can slide smoothly in the light shielding tube. The receiving groove 103a ensures the precise movement and stability of the light shielding cover 106 by providing a guiding function for the limiting ring 110. The internal sliding connection of the receiving groove 103a is provided with the limiting ring 110. The front end of the limiting ring 110 is fixedly connected to the rear wall of the light shielding cover 106. The limiting ring 110 guides and limits the range of movement of the light shielding cover 106, ensuring that the light shielding cover can slide smoothly and does not deviate, so that it can accurately block external light sources during the detection process. The light shielding cover 106 is slidably connected to the outside of the fixed platform 101. Its function is to be able to be easily opened or closed as needed to effectively block interference from external light sources, ensure that the light source is not affected by external light sources when it shines on the lens, and improve the accuracy and reliability of light transmission detection. Through the cooperation between the limiting ring 110 and the light shielding cover 106, the opening and closing state of the light shielding cover can be easily adjusted, thereby ensuring the stability of the light environment during the detection process.
