Description

Technical Field

[0001] This invention relates to the field of optical lens testing equipment technology, specifically to a composite photoelectric testing device for lens adhesive layer thickness and adhesive aberration. Background Technology

[0002] After optical lenses undergo cementation, uneven cement layer thickness and aberrations caused by the cementation directly affect the imaging accuracy of the entire optical lens system. Traditional inspection methods involve two separate checks: first, a micrometer is used to measure the cement layer thickness, and then an interferometer is used to detect cementation aberrations. These two lens clamping processes involve inconsistent positioning references, easily leading to inspection errors and low efficiency. Furthermore, both sets of equipment occupy significant space and have high purchase costs. Most existing integrated inspection devices can only collect either thickness or aberration data, unable to simultaneously collect both parameters and establish real-time thickness data. Aberration correspondence is not conducive to analyzing the causes of bonding defects.

[0016] 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.

[0017] Please see Figures 1-4The present invention provides a technical solution: a composite photoelectric detection device for lens adhesive layer thickness and adhesive aberration, comprising a lens composite photoelectric detection device 8, a base 1, a translation stage assembly 2, a lens clamping assembly 3, a thickness detection module 4, an aberration detection module 5, a lifting bracket assembly 6, and an industrial control computer 7. The lens composite photoelectric detection device 8 is provided with a base 1, which is arranged horizontally. The translation stage assembly 2 is fixedly installed on one side of the upper surface of the base 1, and the lifting bracket assembly 6 is fixedly installed on the other side of the upper surface of the base 1.

[0018] The lens clamping assembly 3 is installed on the top of the translation stage assembly 2, and the bonding lens to be tested is installed on the lens clamping assembly 3.

[0019] The translation table assembly 2 includes two parallel linear guides, a sliding seat, a servo motor, and a lead screw. The two linear guides are fixed to the base 1 by bolts. The sliding seat is slidably mounted above the two linear guides. The servo motor is fixedly installed at one end of the linear guide. The output shaft of the servo motor is coaxially connected to the lead screw. The lead screw and the sliding seat are threaded together. The servo motor drives the lead screw to rotate, causing the sliding seat to move laterally back and forth along the linear guides.

[0020] The lens clamping assembly 3 includes a support base, a fixed clamping block, a movable clamping block, and an adjusting screw. The support base is bolted to the top of the sliding seat, the fixed clamping block is fixedly connected to one side of the support base, and the adjusting screw is threaded onto the other side of the support base. The end of the adjusting screw is rotatably connected to the movable clamping block. The cemented lens to be tested is vertically clamped between the fixed clamping block and the movable clamping block. The center of the cemented lens to be tested is located in the same vertical plane as the optical path centerline of the thickness detection module 4 and the aberration detection module 5.

[0021] The lifting support assembly 6 is set along the vertical direction. The lifting support assembly 6 includes a vertical column, a vertical slide rail and two sets of locking sliders. The vertical column is fixedly fixed on the base 1. The vertical slide rail is fixedly installed on the side wall of the vertical column. The two sets of locking sliders are slidably installed on the vertical slide rail. Locking bolts are installed on the locking sliders. The thickness detection module 4 and the aberration detection module 5 are respectively fixedly installed on the two sets of locking sliders.

[0022] The thickness detection module 4 is a laser displacement sensor. The laser displacement sensor faces downwards towards the cemented lens to be tested, and the laser emitted by the laser displacement sensor vertically illuminates the cemented layer position of the cemented lens to be tested.

[0023] The aberration detection module 5 includes a parallel light source, a collimating lens, and a CMOS image sensor. The parallel light source and the collimating lens are coaxially fixed on the first mounting plate, and the CMOS image sensor is fixed on the second mounting plate. The first mounting plate and the second mounting plate are respectively fixed on the locking slider. The light beam emitted by the parallel light source is formed into parallel light through the collimating lens. The parallel light passes perpendicularly through the cemented lens under test and is then projected onto the CMOS image sensor.

[0024] The lifting bracket assembly 6 is equipped with an aberration detection module 5 and a thickness detection module 4 from top to bottom. Both the thickness detection module 4 and the aberration detection module 5 can be vertically raised and lowered along the lifting bracket assembly 6. The thickness detection module 4 and the aberration detection module 5 are electrically connected to the industrial control computer 7 through wiring. The industrial control computer 7 is fixedly installed on the side of the base 1.

[0025] The parallel light source, collimating lens, cemented lens under test, and CMOS image sensor are all on the same optical axis.

[0026] The industrial computer 7 has built-in data processing software. The industrial computer synchronously receives the thickness data collected by the thickness detection module 4 and the spot image data collected by the aberration detection module 5. It matches and stores the thickness parameters and bonding aberration parameters at the same detection position and outputs the detection results.

[0027] A composite photoelectric detection device for lens adhesive layer thickness and adhesive aberration is assembled from seven core components: a base 1, a translation worktable assembly 2, a lens clamping assembly 3, a thickness detection module 4, an aberration detection module 5, a lifting bracket assembly 6, and an industrial control computer 7.

[0028] The base 1 is a single horizontal steel reference platform, which is leveled and arranged as the bearing reference for all components of the equipment. The upper surface of the base 1 is divided into left and right sections. The left side is fixed with bolts to the translation worktable assembly 2, and the right side is vertically fixed with the lifting support assembly 6. The two functional units are arranged independently and do not interfere with each other, with sufficient space reserved for operation and optical path.

[0029] The translation stage assembly 2 includes two parallel, equal-height linear guides, a sliding seat, a servo motor, and a lead screw. The two linear guides are parallel, equal in height, and symmetrically secured to the left side plane of the base 1 with countersunk bolts, ensuring a straight sliding reference. The bottom of the sliding seat has a groove matching the guides. The sliding seat is mounted above the two linear guides and can only slide linearly laterally along the guides. The servo motor flange is fixed to a motor support at one end of the linear guides. The motor output shaft is rigidly connected to the lead screw coaxially via a coupling. The lead screw horizontally passes through the sliding seat and precisely engages with the internal threaded pair of the sliding seat. The servo motor receives displacement pulse signals from the industrial control computer 7, driving the lead screw to rotate forward and backward. The lead screw, relying on the threaded pair transmission, drives the sliding seat to move precisely laterally back and forth along the guides, achieving automatic multi-point scanning and positioning of the laminated lens under test.

[0030] This translation stage adopts a servo screw linear transmission structure, which has high displacement repeatability and positioning accuracy, smooth movement without slippage, and can realize continuous detection of the entire lens area, replacing manual lens movement and eliminating the reference offset error caused by manual positioning.

[0031] The lens clamping assembly 3 is bolted to the top of the sliding seat of the translation worktable and moves laterally synchronously with the sliding seat. The clamping assembly consists of a support base, a fixed clamping block, a movable clamping block, and an adjusting screw. The bottom of the support base has pre-drilled bolt holes for locking and fixing to the top surface of the sliding seat. One side of the support base has an integrally formed fixed clamping block, and the other side has a threaded through hole for mounting the adjusting screw. The end of the adjusting screw is rotatably connected to the movable clamping block through a rotary bearing. When the screw rotates, it only pushes the movable clamping block to move horizontally and does not drive the clamping block to rotate, thus avoiding scratching the lens surface.

[0032] The cemented lens to be tested is placed vertically between the fixed clamp and the movable clamp. The lens can be clamped or loosened by rotating the adjusting screw. After assembly, ensure that the geometric center of the cemented lens to be tested and the optical path center line of the thickness detection module 4 and aberration detection module 5 above fall in the same vertical plane. Ensure that the laser thickness measurement optical path and the aberration detection optical path are vertically aligned with the cemented layer of the lens, and that there is no offset or eccentric interference in the optical path.

[0033] The clamping structure adopts a single-sided adjustable flexible clamping, which makes it easy to install and remove lenses. The clamping force is controllable and will not squeeze the lens and cause deformation. The uniform vertical clamping method uses the same clamping reference for thickness and aberration detection, eliminating the need for secondary lens installation and removal, thus eliminating the positioning deviation caused by multiple clamping from the root.

[0034] The lifting support assembly 6 is vertically fixed to the right side of the base 1. The core components include a vertical column, a vertical slide rail, and two sets of independent locking sliders. The bottom flange of the vertical column is rigidly locked to the base with expansion bolts to ensure that the column is not tilted. The vertical slide rail is fixed vertically along the entire length of the column side wall. The two sets of locking sliders are independently mounted on the vertical slide rail. Each locking slider is equipped with a locking bolt on its side. Loosening the bolt allows the slider to slide freely up and down along the slide rail. Tightening the bolt locks the slider in place at any height.

[0035] Two sets of locking sliders are sequentially assembled from top to bottom: aberration detection module 5 and thickness detection module 4. The two detection modules can be raised and lowered independently without interfering with each other's height adjustment stroke. The aberration optical path height and laser thickness measurement focusing height can be adjusted separately according to the different diameters and thicknesses of the cemented lenses.

[0036] The split, independently adjustable slider structure is compatible with the inspection of multiple lens specifications. The optical path height is flexibly adjustable, and focusing and calibration can be completed without disassembling the inspection module. The adjustment is convenient. The vertical column has an integrated rigid structure, and there is no shaking during the lifting process, ensuring the long-term stability of the optical path.

[0037] The thickness detection module 4 uses a high-precision laser displacement sensor. The sensor body is fixed on the lower locking slider, the laser emitter of the sensor is vertically downward, and the laser beam is vertically downward aligned with the bonding layer area of ​​the bonding lens to be tested on the lower clamping station. The laser displacement sensor is electrically connected to the side industrial control computer 7 through a shielded signal line, and transmits the raw data of the bonding layer thickness collected by laser ranging to the industrial control computer in real time.

[0038] Employing a non-contact laser thickness measurement solution, this method eliminates the need to contact the lens adhesive layer, preventing scratches to the optical coating. The laser is incident perpendicularly on the adhesive layer, accurately capturing the upper and lower interfaces of the adhesive layer between the two lenses. It offers high thickness measurement accuracy and fast response speed, and can simultaneously follow the lens's lateral scan to continuously acquire full-area thickness data.

[0039] The aberration detection module 5 is assembled on the upper locking slider and is divided into two parts: the upper optical path unit and the lower imaging unit. They are fixed on two independent mounting plates respectively. The first mounting plate fixes the parallel light source and the collimating lens. The two are coaxially assembled. The beam emitted from the parallel light source is converted into a standard parallel beam by the collimating lens. The second mounting plate fixes the CMOS image sensor, and the imaging receiving surface is vertically aligned with the parallel light path.

[0040] The parallel light source, collimating lens, cemented lens under test, and CMOS image sensor are strictly coaxial, forming a complete aberration detection optical path: the parallel light passes vertically from top to bottom through the vertically placed cemented lens under test. Due to the uneven thickness of the cemented layer, the stress of the cemented layer, and the cementing misalignment, the parallel light will be distorted. The distorted light spot is completely projected onto the photosensitive surface of the CMOS image sensor. The CMOS sensor acquires the light spot image in real time and transmits it to the industrial control computer for image analysis.

[0041] The modular, separate optical path design allows for independent height adjustment of the light source collimation unit and imaging unit, facilitating coaxial optical path calibration. High-speed CMOS image acquisition can fully record wavefront distortion caused by cementation, quantitatively calculate cementation aberration parameters such as cementation spherical aberration and astigmatism, and provide quantitative and traceable detection results.

[0042] The industrial control computer (ICC) is fixedly mounted on the side bracket of the base, avoiding the optical path and lens operation area, and does not occupy the inspection space. The ICC is pre-installed with dedicated data processing software, establishing bidirectional data communication with the laser displacement sensor and CMOS image sensor via signal lines. During equipment operation, the ICC synchronously receives real-time thickness values ​​output by the thickness detection module and the original spot image transmitted by the aberration detection module. Based on the real-time displacement coordinates of the translation stage, the software binds, matches, and synchronously stores the adhesive layer thickness data and spot distortion aberration data at the same lateral detection point, automatically generating a thickness-aberration correlation inspection report, storing it locally, and displaying it on the screen.

[0043] The integrated data synchronization processing unit enables the synchronous acquisition of thickness and aberration data from the same source. It can directly establish the correspondence between the adhesive layer thickness distribution and the adhesive aberration, making it convenient for staff to analyze the influence of defects such as uneven adhesive layer thickness, air bubbles, and delamination on imaging aberrations.

[0044] Complete equipment operation process: Loosen the two sets of locking slider bolts on the lifting bracket. Adjust the height of the aberration detection module and the thickness detection module by sliding them up and down according to the size of the cemented lens to be tested. Complete the optical path focusing and coaxial calibration. After calibration, tighten the locking bolts to fix the module height. Rotate the adjusting screw of the lens clamping assembly to open the gap between the fixed clamping block and the movable clamping block. Place the cemented lens to be tested vertically into the clamping position. Rotate the adjusting screw in the opposite direction to clamp the lens. Confirm that the center of the lens is coplanar with the center lines of the two optical paths. The clamping is completed. The entire clamping and positioning process only requires one clamping operation.

[0045] The operator inputs parameters such as lens model, detection scanning range, and sampling interval into the industrial control computer interface and starts the automatic detection program. The industrial control computer sends motion control signals to the servo motor of the translation worktable. The servo motor drives the lead screw to move the sliding seat, lens clamping assembly, and lens under test horizontally at a uniform speed along the linear guide rail.

[0046] During the lateral movement of the lens, the laser displacement sensor of the thickness detection module continuously emits vertical laser to measure the thickness of the adhesive layer at the current position in real time, and the thickness data is uploaded to the industrial control computer in real time; at the same time, the aberration detection module above continuously outputs standard parallel light. After the parallel light penetrates the lens, it forms a distorted spot. The CMOS image sensor continuously acquires the spot image at the corresponding position and transmits it synchronously to the industrial control computer. The data acquisition timing of the two modules is completely synchronized, and the same displacement coordinate corresponds to a set of thickness and aberration data.

[0047] The industrial control computer's built-in software reads the worktable's displacement coordinates in real time and binds the thickness parameters under the same coordinates to the spot image. The software performs grayscale, distortion, and wavefront fitting calculations on the spot image to quantitatively calculate the bonding aberration value at that point and establish a three-dimensional correlation dataset of "position-adhesive layer thickness-bonding aberration". After all scanning strokes are completed, the software automatically draws the adhesive layer thickness distribution curve and the global aberration distribution cloud map, generates a complete inspection report, and supports real-time screen viewing, local file saving, and data export.

[0048] After the entire lens scanning inspection is completed, the industrial control computer controls the servo motor to drive the sliding seat to reset to the initial clamping position; rotate the adjusting screw to loosen the clamping block, remove the inspected cemented lens, replace it with the next lens to be tested, and repeat the above process to continuously perform batch inspections.

[0049] This invention relates to a composite photoelectric inspection device integrating adhesive layer thickness detection and bonding aberration detection. Using a horizontal base as a unified bearing reference, it employs a translational worktable to achieve automatic lateral full-area scanning of the lens. An adjustable clamping assembly enables single-shot lens clamping and fixation. A lifting bracket houses two independently adjustable detection modules, with aberration optical paths and laser thickness measurement optical paths arranged from top to bottom. Both detection optical paths share the same lens clamping reference, enabling simultaneous acquisition of adhesive layer thickness and bonding aberration data at the same location. An industrial control computer handles simultaneous dual-channel data acquisition, coordinate matching, quantization calculation, and result output. The device integrates two photoelectric detection methods: laser non-contact thickness measurement and parallel-beam CMOS wavefront aberration detection. By unifying the clamping reference and synchronously acquiring dual parameters, it balances detection accuracy, efficiency, and space utilization. It can intuitively establish the correlation between adhesive layer thickness and bonding aberration, providing comprehensive data support for tracing defects in optical lens bonding processes and optimizing processes. It is suitable for mass production quality inspection scenarios of optical lenses.
