Description

Technical Field

[0001] This invention relates to the field of optical lens manufacturing technology, and in particular to an integrated device for subsurface inspection and laser repair of optical lenses. Background Technology

[0002] High-precision optical lenses are core components of optical systems such as optoelectronic imaging, laser transmission, and precision detection. The integrity of the lens's surface and subsurface directly affects the overall optical precision and imaging quality. To ensure that optical lenses are free from defects such as subsurface microcracks, hidden scratches, and internal impurities, comprehensive subsurface inspection of both the front and back of the lens is required during the production process, and laser repair operations are carried out on the defective locations to meet high-precision optical standards.

[0003] Currently, in traditional optical lens subsurface inspection and repair processes, due to limitations in the inspection structure, the equipment can only scan and inspect one side of the lens. After completing the inspection of one side, the lens must be flipped before the other side can be inspected. Existing flipping methods mostly rely on manual operation with external clamps to hold the lens edges for flipping and repositioning. This method has certain drawbacks: traditional clamps are mostly rigid clamping structures, making it difficult to accurately control the clamping force, which can easily cause squeezing damage, edge chipping, indentation, and surface scratches to ultra-thin, high-precision optical lenses, compromising the optical surface accuracy of the lens; at the same time, the repeated clamping, disassembly, and repositioning process is cumbersome, and the flipping positioning benchmark is not uniform, which can easily cause inspection deviations, missed detections, and false detections, seriously affecting the inspection accuracy and repair consistency of both sides of the lens. The amount of manual intervention is large and the work efficiency is low. Therefore, an integrated device for optical lens subsurface inspection and laser repair is proposed to solve the above problems. Summary of the Invention

[0004] To overcome the above shortcomings, this invention provides an integrated device for subsurface inspection and laser repair of optical lenses. It aims to improve the existing technology where subsurface inspection of optical lenses requires manual operation with external clamps for flipping and reinstallation. This process is cumbersome, has low automation, and poor work efficiency. Rigid clamping can easily cause secondary damage to the lens, such as indentations, chipping, and scratches. Furthermore, multiple clamping operations can lead to inconsistent positioning benchmarks, which can easily cause inspection deviations, missed detections, false detections, and insufficient repair consistency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an integrated device for subsurface inspection and laser repair of optical lenses, comprising a processing table, wherein the processing table is provided with an image detection module one, an image detection module two, and a laser repair module, and the processing table is provided with a rotation and flipping mechanism for optical lenses, wherein the flipping action of the optical lenses is located between the image detection module one and the image detection module two, and the rotation and flipping mechanism includes: A rotating base is disposed above a processing table, and a fixing component is fixedly connected to the upper side of the processing table. The rotating base is rotatably connected to the fixing component. A fixed sleeve, wherein multiple sets of the fixed sleeves are arranged in a ring on a rotating base, and multiple sets of flipping components are arranged in a ring on the rotating base; An auxiliary flipping connector is fixedly connected to the inner surface of a fixing member; A drive module is installed on the lower side of the processing table and is used to drive the rotating seat to rotate.

[0006] As a further description of the above technical solution: The fixed sleeve is provided with a cam guide groove.

[0007] As a further description of the above technical solution: The flipping assembly includes a round rod, a placement frame, a fixing plate, a connecting rod, a blocking member, and a connecting component. The round rod passes through the rotating seat and is rotatably connected to it. The placement frame is fixedly connected to the end of the round rod away from the connecting component. The fixing plate is fixedly connected to the outer wall of the round rod. The blocking member is fixedly connected to the end of the connecting rod. The connecting rod passes through the fixing plate and is slidably connected to it. The end of the connecting rod away from the blocking member is slidably connected to a cam guide groove. The connecting component is located at the end of the round rod away from the placement frame. There are two sets of connecting rods and blocking members.

[0008] As a further description of the above technical solution: The connecting assembly includes a connecting column, an arc-shaped plate, and a rotating wheel. The connecting column is fixedly connected to the round rod, the arc-shaped plate is fixedly connected to the end of the connecting column away from the round rod, and the rotating wheel is rotatably connected to the side of the arc-shaped plate away from the connecting column.

[0009] As a further description of the above technical solution: The side of the blocking member closest to the placement frame is made of a flexible material.

[0010] As a further description of the above technical solution: A ball bearing is embedded at the end of the connecting rod away from the blocking member.

[0011] As a further description of the above technical solution: The fixing component has an inclined groove and a notch, which are matched with the rotating wheel.

[0012] As a further description of the above technical solution: The auxiliary flipping connector consists of a fixed frame and a guide block. The fixed frame is fixedly connected to the inner surface of the fixing component, and the guide block is fixedly connected to the fixed frame.

[0013] As a further description of the above technical solution: The drive module includes a stepper motor and a reducer. The reducer is fixedly installed on the lower side of the processing table, and the stepper motor is fixedly installed on the reducer to drive the reducer. The output shaft of the reducer is fixedly connected to the rotating seat.

[0014] As a further description of the above technical solution: A positioning sleeve is fixedly installed on the processing table, and the output shaft of the reducer is sleeved by the positioning sleeve.

[0015] The present invention has the following beneficial effects: 1. In this invention, by setting a rotating flipping mechanism, the optical lens can automatically flip and change direction between the two detection modules after placement, eliminating the need for repeated disassembly, clamping, and alignment calibration. This greatly simplifies the process of double-sided lens inspection and repair, reduces manual intervention, and effectively solves the problems of cumbersome traditional processes, low automation, and poor batch operation efficiency. It improves the efficiency of double-sided optical lens inspection and laser repair, and is suitable for the needs of high-precision lens mass inspection.

[0016] 2. In this invention, by using the auxiliary flipping connector and the flipping assembly together, the blocking component can block the optical lens during the flipping process, preventing the optical lens from falling off the placement frame. After the flipping is completed, the blocking component can move away from the placement frame, preventing the blocking component from blocking the optical lens during photo inspection, and avoiding secondary damage such as lens indentation, chipping, scratches and surface deformation caused by traditional rigid clamps.

[0017] 3. In this invention, an integrated continuous processing structure is adopted, and the lens flipping process does not leave the workstation. It always maintains a unified assembly standard, eliminates the positioning deviation caused by traditional multiple clamping, and effectively avoids problems such as missed detection, false detection, misalignment during repair, and poor consistency, thereby improving the performance of the device.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Reference Figures 1-4 This invention provides an embodiment of an integrated device for subsurface inspection and laser repair of optical lenses, comprising a processing table 1, on which are mounted a first imaging inspection module 2, a second imaging inspection module 3, and a laser repair module 4. The processing table 1 also includes a rotating and flipping mechanism 5 for the optical lenses, with the lens flipping action located between the first and second imaging inspection modules 2 and 3. The first and second imaging inspection modules 2 and 3 can respectively perform subsurface defect scanning and inspection on both sides of the optical lens. The laser repair module 4 can precisely repair detected defects such as microcracks and hidden scratches using laser. The rotating and flipping mechanism 5 is positioned between the two inspection modules, enabling automatic lens reversal and integrating double-sided inspection, automatic flipping, and laser repair functions into one device, improving operational continuity.

[0022] The rotating flipping mechanism 5 includes a rotating base 51, a fixed sleeve 52, an auxiliary flipping connector 55, and a drive module 56. The rotating base 51 is positioned above the processing table 1, and a fixing member 54 is fixedly connected to the upper side of the processing table 1. The rotating base 51 is rotatably connected to the fixing member 54. Multiple sets of fixed sleeves 52 are arranged in a ring on the rotating base 51, and multiple sets of flipping components 53 are arranged in a ring on the rotating base 51. The auxiliary flipping connector 55 is fixedly connected to the inner surface of the fixing member 54. The drive module 56 is installed on the lower side of the processing table 1 and is used to drive the rotating base 51 to rotate. The fixing member 54 provides rotational support for the rotating base 51, ensuring that the rotating base 51 rotates smoothly. The multiple sets of fixed sleeves 52 arranged in a ring and the flipping components 53 can realize synchronous clamping operations for lenses at multiple workstations, effectively improving batch processing efficiency. The auxiliary flipping connector 55, in conjunction with the rotation trajectory, assists in the precise flipping and positioning of the lenses. The drive module 56 provides stable power input to the overall rotating workstation, realizing automated continuous rotating feeding and flipping actions.

[0023] Reference Figures 5-7The fixed sleeve 52 has a cam guide groove 521, the fixed member 54 has an inclined groove 541, and the fixed member 54 has a notch 542 that matches the rotating wheel 538. The flipping assembly 53 includes a round rod 531, a placement frame 532, a fixing plate 533, a connecting rod 534, a blocking member 535, and a connecting assembly. The round rod 531 passes through the rotating seat 51 and is rotatably connected to the rotating seat 51. The placement frame 532 is fixedly connected to the end of the round rod 531 away from the connecting assembly. The fixing plate 533 is fixedly connected to the outer wall of the round rod 531. The blocking member 535 is fixedly connected to the outer wall of the round rod 531. A fixed connection is made to the end of the connecting rod 534, which passes through the fixed plate 533 and is slidably connected to it. The end of the connecting rod 534 away from the blocking member 535 is slidably connected to the cam guide groove 521. The connecting assembly is located at the end of the round rod 531 away from the placement frame 532. Two sets of connecting rods 534 and blocking members 535 are provided. The connecting assembly includes a connecting post 536, an arc-shaped plate 537, and a rotating wheel 538. The connecting post 536 is fixedly connected to the round rod 531, and the arc-shaped plate 537 is fixedly connected to the end of the connecting post 536 away from the round rod 531. The rotating wheel... 538 is rotatably connected to the side of the arc plate 537 away from the connecting post 536. The auxiliary flipping connector 55 consists of a fixed frame 551 and a guide block 552. The fixed frame 551 is fixedly connected to the inner surface of the fixed member 54, and the guide block 552 is fixedly connected to the fixed frame 551. During the rotation of the rotating seat 51, it can drive multiple sets of flipping components 53 to move. When the flipping component 53 moves to the inclined groove 541, the rotating wheel 538 can enter the notch 542 under the guidance of the guide block 552. At this time, as the rotating seat 51 continues to rotate, the arc plate... 537 rotates 180 degrees, causing the connecting column 536 and the round rod 531 to rotate, thus flipping the placement frame 532. During this process, the fixing plate 533 drives the connecting rod 534 to rotate, and the connecting rod 534 moves in the cam guide groove 521, causing the connecting rod 534 to drive the blocking member 535 to move. Thus, during the flipping process, the blocking member 535 can block the optical lens, preventing the optical lens from falling off the placement frame 532. After the flipping is completed, the blocking member 535 can move away from the placement frame 532, preventing the blocking member 535 from blocking the optical lens during the photo-taking inspection.

[0024] Furthermore, the side of the blocking member 535 closest to the placement frame 532 is made of flexible material to prevent damage to the optical lens when the blocking member 535 moves.

[0025] Furthermore, a ball bearing is embedded at the end of the connecting rod 534 away from the blocking member 535 to reduce the friction of the connecting rod 534 moving in the cam guide groove 521.

[0026] Reference Figures 1-3The drive module 56 includes a stepper motor and a reducer. The reducer is fixedly installed on the lower side of the processing table 1, and the stepper motor is fixedly installed on the reducer to drive the reducer. The output shaft of the reducer is fixedly connected to the rotating seat 51. The stepper motor works with the reducer to achieve deceleration drive, which can precisely control the rotation angle, speed and start / stop of the rotating seat 51. It can match the process rhythm of lens inspection, flipping and repair, and ensure accurate alignment of intermittent rotation in multiple workstations.

[0027] In addition, a positioning sleeve is fixedly installed on the processing table 1, and the output shaft of the reducer is sleeved by the positioning sleeve for positioning the rotation of the output shaft of the reducer.

[0028] It should be noted that all the above electrical components are existing technology products. Those skilled in the art should select, install and complete the circuit debugging work according to the needs of use to ensure that each electrical appliance can work normally. All components are general standard parts or parts known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here. The standard parts used in this application can be purchased from the market. The specific connection methods of each part are all connected by conventional means such as riveting and welding that are mature in the prior art. The standard parts are all conventional models in the prior art. The circuit connection adopts conventional connection methods in the prior art.

[0029] Working principle: During use, the staff places the optical lenses to be inspected and repaired into the placement frames 532 of each station of the rotating seat 51 in sequence. After the equipment is started, the stepper motor in the drive module 56 provides power, and after the speed is reduced and stabilized by the reducer, it drives the output shaft to rotate. The positioning sleeve provides radial positioning constraint for the output shaft of the reducer to ensure the rotation accuracy and stability of the output shaft. This drives the rotating seat 51 to rotate smoothly and intermittently above the fixed part 54. During the rotation of the rotating seat 51, it simultaneously drives multiple sets of flipping components 53 and the fixed sleeve 52 to revolve as a whole, so that the placement frames 532 containing the optical lenses are sequentially transferred to each work station.

[0030] When the lens is transferred to the imaging inspection module 2 station, the imaging inspection module 2 performs a full scan of the upper surface of the optical lens to complete the single-sided subsurface defect detection of the lens and accurately collect defect information such as micro-cracks and hidden scratches. After the inspection is completed, the rotating seat 51 continues to rotate, transporting the lens to the flipping station. At this time, the flipping component 53 follows the revolution, and the rotating wheel 538 slides along the inclined groove 541 of the fixing component 54 under the guidance of the guide block 552 in the auxiliary flipping connector 55, and finally embeds into the recess 542. As the rotating seat 51 continues to rotate, the arc plate 537 is limited by the trajectory to achieve a 180-degree flip, and the connecting column 536 drives the round rod 531 to rotate synchronously, completing the overall automatic flipping action of the placement frame 532 and the optical lens.

[0031] During the flipping operation, the round rod 531 drives the fixed plate 533 to rotate synchronously, causing the connecting rod 534 to slide along the cam guide groove 521 of the fixed sleeve 52. The ball bearings at the end of the connecting rod 534 effectively reduce sliding friction, ensuring smooth and stable movement. During the flipping process, the two sets of blocking components 535 synchronously approach the placement frame 532, forming a limiting block on the optical lens, effectively preventing the lens from falling off and shifting during the flipping process. After the flipping action is completed, the connecting rod 534 is linked to reset again, causing the blocking components 535 to automatically move away from the placement frame 532, removing the obstruction and avoiding obstruction of the field of view for subsequent inspection processes.

[0032] After the lens is flipped, the rotating seat 51 continues to move the lens to the imaging inspection module 2, station 3. The imaging inspection module 2, station 3 performs subsurface defect scanning inspection on the other side of the optical lens, completing the complete double-sided defect inspection of the lens. After the inspection system records the location and type of all defects on both sides of the lens, the defective lens is transported to the laser repair module 4, where the laser repair module 4 performs precise laser repair on defects such as subsurface cracks and hidden scratches. The entire set of equipment relies on a multi-station ring rotating structure to automatically complete the integrated continuous operation of lens loading, single-sided inspection, automatic mechanical flipping, double-sided inspection, and laser repair.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
