Description

Technical Field

[0001] This invention relates to the field of optical lens manufacturing technology, specifically to an integrated device for subsurface non-destructive testing and laser repair of optical lenses. Background Technology

[0002] Optical lenses are core optical components made of highly transparent optical materials (such as optical glass, quartz, resin, sapphire, etc.) and are used to precisely control the propagation characteristics of light (refraction, reflection, transmission, focusing, filtering, etc.). They are fundamental components of optical systems (such as lenses, microscopes, laser equipment, imaging instruments, etc.), and their quality directly determines the imaging accuracy, light transmission efficiency, and functional realization of the optical system.

[0003] However, the detection and repair of subsurface wear on optical lenses requires two separate sets of equipment: first, non-destructive testing equipment is used to inspect for wear, and then the lenses are manually transported to laser repair equipment for processing. This model has significant drawbacks: first, the handling process is time-consuming, and manual operation can easily lead to collisions and friction between the lenses, causing new surface damage; second, the step-by-step operation cannot be seamlessly integrated into batch processing, as each lens needs to complete the loading-inspection-handling-repair-unloading process separately, with a single-shift processing capacity of less than 100 lenses, which is insufficient to meet the high-efficiency processing requirements of mass production scenarios for optical lenses. Summary of the Invention

[0012] Preferably, a negative pressure fan is provided at the bottom of the inner sidewall of the processing table. Three sets of hoses are fixedly connected to the suction end of the negative pressure fan. A negative pressure head is provided at the end of the hose away from the negative pressure fan. A connecting bracket is fixedly connected to the outer sidewall of the negative pressure head. An air duct is opened on the inner sidewall of the top column. A placement tray is rotatably connected to the top of the inner sidewall of the top column. A fan blade is fixedly connected to the center of the bottom end of the placement tray. A ball bearing is rotatably connected to the surface of the placement tray away from the center point.

[0013] Preferably, the automatic replenishment component includes a storage box, and a triangular block is elastically connected to the inner sidewall of the bottom end of the storage box by a return spring.

[0014] Preferably, the fixed column is fixedly connected to the bottom end of the inner sidewall of the processing table, and the rotary disk is rotatably connected to the center of the inner sidewall of the processing table.

[0015] Preferably, a conveying guide groove is provided on the right side surface of the processing table, and the outer arc surface of the top column is in contact with the inner wall of the conveying guide groove.

[0016] Preferably, the end of the negative pressure head away from the hose is in contact with the lower surface of the top column, and the connecting bracket is fixedly connected to the top of the inner side wall of the processing table.

[0017] Preferably, a through cavity is formed at the center of the top column, and multiple sets of air inlets are formed on the surface of the placement plate.

[0018] Preferably, the storage box is fixedly connected to the left side surface of the processing table, the discharge port on the lower surface of the storage box corresponds to the groove on the surface of the negative pressure fan, one end of the reset spring is fixedly connected to the rear end of the triangular block, and the other end of the reset spring is fixedly connected to the inner wall at the bottom of the storage box.

[0019] Preferably, the triangular block is slidably connected to the inner wall at the bottom of the storage box, and two sets of the triangular blocks are provided, with inclined surfaces on the surfaces of both sets of the triangular blocks.

[0020] This invention provides an integrated device for subsurface non-destructive testing and laser repair of optical lenses. It offers the following advantages:

[0021] 1. This invention utilizes a rotating disk and four sets of top columns in a cyclical operation structure to automatically replenish, inspect, and repair the entire process: the motor-driven rotating disk drives the four sets of top columns to rotate synchronously. After a set of top columns completes feeding at the replenishment position, it sequentially rotates to the inspection position and then the repair position. At the same time, the other top columns simultaneously replenish or inspect, forming a multi-station parallel mode. No manual handling is required, avoiding damage during handling. The electric telescopic rod can push the top columns to move precisely along the conveyor guide, ensuring that the lens is aligned with the laser repair module during repair, eliminating the need for recalibration and further shortening the processing time for a single lens.

[0022] 2. This invention relies on a dynamic detection structure driven by negative pressure and assisted by beads to solve the problems of single angle and inaccurate positioning: The negative pressure fan generates airflow through the air duct, driving the fan blades and the placement plate to rotate. The beads on the surface of the placement plate periodically lift the lens, achieving 360° multi-angle tilting within a range of ±15°. The detection module can cover the entire subsurface area of ​​the lens, reducing the missed detection rate to below 5%. The detected wear position is transmitted to the control and display module in real time. The laser repair module directly positions itself according to the displayed data. With the precise movement of the top column, the repair deviation is controlled within ±0.05mm, meeting the quality requirements of high-precision optical lenses.

[0023] 3. The storage box of the automatic replenishment component of this invention can store lenses in batches. When the lens is suctioned by negative pressure, it is pressed against the inclined surface of the triangular block. The triangular block overcomes the elastic force of the return spring and slides outward. The lens is automatically dropped to the top column, and the replenishment speed is increased to 10-12 pieces / minute, which is 200% more efficient than manual replenishment. The negative pressure fan continuously suctions the lens through the negative pressure head and air duct. No matter whether the placement tray rotates or tilts, the lens does not shift, and the damage risk of traditional mechanical clamping is avoided. The triangular block is automatically reset by the return spring to ensure that subsequent lenses are dropped smoothly. No manual intervention is required throughout the process, which reduces labor costs and reduces lens damage caused by manual operation. Attached Figure Description

Detailed Implementation

[0032] The technical solutions in 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.

[0033] Example:

[0034] Please see the appendix Figure 1 -Appendix Figure 7 This invention provides an integrated device for non-destructive testing and laser repair of subsurface optical lenses, including a processing table 1, a detection module 2 on the side wall of the rear end of the processing table 1, a laser repair module 3 on the right side surface of the processing table 1, a control and display module 4 on the front surface of the processing table 1, a negative pressure multi-angle support component 6 on the inner side wall of the processing table 1, and an automatic feeding component 5 on the left side surface of the processing table 1.

[0035] Detection module 2 is used to detect whether the surface of the optical lens has wear;

[0036] Laser repair module 3 is used to laser repair optical lenses whose surfaces have been worn by the detection module 2.

[0037] The control display module 4 is used to display the location of the detection and the location of the laser repair on the surface of the optical lens;

[0038] Automatic replenishment component 5 is used to store the optical lenses to be tested and realize automatic replenishment;

[0039] The negative pressure multi-angle support component 6 is used for optical lenses to enable automatic replenishment and continuous operation of detection and laser repair.

[0040] Furthermore, the negative pressure multi-angle support component 6 includes a fixed column 605, with a motor 606 fixedly connected to the top of the fixed column 605. The output shaft of the motor 606 is fixedly connected to a rotating disk 607. Driven by the motor 606, the rotating disk 607 can rotate, thereby achieving the entire process of automatic lens repair, inspection, and laser restoration. The fixed column 605 is fixedly connected to the bottom end of the inner sidewall of the processing table 1, and the rotating disk 607 is rotatably connected to the center of the inner sidewall of the processing table 1. Four sets of electric telescopic rods 608 are fixedly connected to the lower surface of the rotating disk 607, and the telescopic ends of the four sets of electric telescopic rods 608 are all fixedly connected to top columns 609. By setting the electric telescopic rods 608, when a lens placed inside a set of top columns 609 is worn and needs repair, it can be repaired by electric telescopic rods. The rod 608 drives the corresponding top column 609 to extend to the laser repair module 3 for laser repair. A conveying guide groove is provided on the right side surface of the processing table 1. The outer arc surface of the top column 609 contacts the inner wall of the conveying guide groove. The contact between the two allows the conveying guide groove of the processing table 1 to guide the movement of the top column 609. A placement groove is provided on the inner side wall of the top of the top column 609. By providing a placement groove on the surface of the top column 609, optical lenses can be placed to facilitate multi-angle inspection and repair. The outer arc surface of the rotating disk 607 has four sets of notches. By providing four sets of notches on the outer arc surface of the rotating disk 607, which correspond to four sets of top columns 609, the rotation of the rotating disk 607 can synchronously rotate the four sets of top columns 609.

[0041] Furthermore, a negative pressure fan 601 is installed at the bottom of the inner sidewall of the processing table 1. Three sets of hoses 602 are fixedly connected to the suction end of the negative pressure fan 601. The negative pressure fan 601 is existing technology. By connecting the three sets of hoses 602 to its outer side, the three sets of hoses 602 generate suction. A negative pressure head 603 is installed at the end of the hose 602 away from the negative pressure fan 601. The end of the negative pressure head 603 away from the hose 602 is in contact with the lower surface of the top column 609. The contact between the two causes the top column 609 to pass through the negative pressure head 603 and the top column when it rotates to the position corresponding to the negative pressure head 603. The cavity at the center of column 609 generates suction, which negatively attracts the optical lens placed on the surface of column 609 to its surface. A connecting bracket 604 is fixedly connected to the top of the inner sidewall of the processing table 1. A connecting bracket 604 is fixedly connected to the outer sidewall of the negative pressure head 603. An L-shaped air duct 610 is formed on the inner sidewall of column 609. When the negative pressure head 603 aligns with the air outlet at the bottom of column 609, the air duct 610 also generates negative pressure, drawing external air in from the bottom of column 609 and expelling it from the upper inner side, thus driving the fan blades 612 to rotate.

[0042] Specifically, a placement plate 611 is rotatably connected to the top of the inner sidewall of the top column 609. A through cavity is opened at the center of the top column 609. Multiple sets of air inlets are opened on the surface of the placement plate 611. A fan blade 612 is fixedly connected to the center of the bottom of the placement plate 611. A bead 613 is rotatably connected to the surface of the placement plate 611 away from the center point. When the fan blade 612 is sucked in by external air, it will drive the placement plate 611 to rotate synchronously. At this time, the bead 613 rotates on the surface of the placement plate 611, thereby periodically lifting and tilting the optical lenses placed on the surface of the placement plate 611 and the bead 613 at multiple angles, thus facilitating the detection module 2 to perform multi-angle detection.

[0043] Furthermore, the automatic feeding component 5 includes a storage box 51. A triangular block 53 is elastically connected to the inner sidewall of the bottom end of the storage box 51 via a return spring 52. The storage box 51 is fixedly connected to the left side surface of the processing table 1. The discharge port on the lower surface of the storage box 51 corresponds to a groove on the surface of the negative pressure fan 601. One end of the return spring 52 is fixedly connected to the rear end of the triangular block 53, and the other end is fixedly connected to the inner wall of the bottom end of the storage box 51. The function of the return spring 52 is to prevent the triangular block 53 from being squeezed by the optical lens. After being moved, the position is automatically reset. The triangular block 53 is slidably connected to the inner wall at the bottom of the storage box 51. There are two sets of triangular blocks 53. The surfaces of the two sets of triangular blocks 53 are provided with inclined surfaces. By providing inclined surfaces on the surfaces of the triangular blocks 53, the optical lenses stacked inside the storage box 51 will be attracted by the negative pressure generated by the negative pressure head 603 directly below them, thereby sucking the bottommost optical lens downward and squeezing the inclined surfaces of the two sets of triangular blocks 53, so that the two sets of triangular blocks 53 move outward synchronously inside the storage box 51.

[0044] Working principle: The storage box 51 of the automatic feeding component 5 stores the optical lens to be tested. When a set of top columns 609 of the negative pressure multi-angle support component 6 rotates to below the storage box 51, the negative pressure fan 601 inside the processing table 1 starts, transmitting suction to the negative pressure head 603 through three sets of hoses 602. The negative pressure head 603 contacts the lower surface of the top column 609, and the suction, through the through holes on the surface of the top column 609 and the placement tray 611, pulls the lowest optical lens in the storage box 51 downwards, causing the lens to press against two sets of three... The inclined surface of corner block 53 causes the triangular block 53 to overcome the elastic force of the return spring 52 and slide outward on the inner wall of the storage box 51, so that the lens can fall smoothly into the placement plate 611 at the top of the top column 609; at this time, the airflow in the air duct 610 drives the fan blade 612 at the bottom of the placement plate 611 to rotate, and the placement plate 611 rotates synchronously. The beads 613 on its surface periodically lift the optical lens and tilt it. The detection module 2 performs multi-angle non-destructive testing on the subsurface of the lens, and the detected wear position is transmitted to the control display module 4 for display in real time.

[0045] After the control display module 4 identifies the wear location of the lens, the motor 606 of the negative pressure multi-angle support component 6 drives the rotating disk 607 (rotating at the center of the inner side of the processing table 1) to rotate. The four sets of notches on the outer arc surface of the rotating disk 607 correspond to the four sets of top columns 609, driving the top columns 609 carrying the worn lens to rotate to the laser repair module 3. The corresponding electric telescopic rod 608 is activated, pushing the top column 609 to move along the conveying guide groove on the right side of the processing table 1, ensuring that the lens is accurately aligned with the laser repair module 3. During the repair process, the negative pressure fan 601 continuously applies negative pressure to the lens on the placement tray 611 through the negative pressure head 603 and the air duct 610 to prevent the lens from shifting. At the same time, the other top columns 609 can simultaneously complete automatic replenishment or inspection operations. Through the cyclic rotation of the rotating disk 607 and the cooperation of the four sets of top columns 609, a continuous operation of automatic replenishment, subsurface inspection, and laser repair of optical lenses is achieved, improving the overall processing efficiency.
