Technical Field

[0001] This invention relates to the field of optical lens processing technology, specifically to a fully automated optical lens assembly and preload adaptive control device and system. Background Technology

[0002] In today's era of rapid technological advancement, optical lenses, as core components of numerous precision optical systems, are widely used in fields such as photography, security monitoring, industrial inspection, medical imaging, and aerospace. Their performance directly determines the imaging quality and application effectiveness of the entire optical system. With the increasing demands from various industries for optical imaging precision, clarity, and functional versatility, the manufacturing technology of optical lenses faces even higher industry requirements.

[0003] In existing optical lens assembly processes, traditional mechanical structures suffer from low positioning accuracy, limited testing methods, and poor interoperability among components. They require significant manual intervention and are prone to assembly deviations. Furthermore, they lack precise testing methods for lens-slot fit, making it impossible to predict abnormal pre-tightening forces after assembly, which can easily lead to quality defects such as lens deformation and loosening. Traditional assembly control methods lack systematic parameter acquisition and precise mathematical calculation models, resulting in poor coordination between the mechanical structure and control system. This makes it difficult to achieve integrated operation of testing, prediction, and assembly, and the assembly efficiency and yield of optical lenses cannot meet the demands of large-scale industrial production.

[0012] Furthermore, inner cylinder components are embedded on the inner walls of both sides of the detection cylinder rod, and an inner slide is provided between multiple sets of inner cylinder components.

[0014] The control system for the fully automated assembly and preload adaptive adjustment device for optical lenses is as follows: The data acquisition module is used to establish data interaction with the sensors of the underlying telescopic detection frame, laser measuring lamp, laser receiver, detection ball and lens conveying equipment, and to collect and standardize lens slot geometric parameter data, dynamic contact pressure data, laser adapter detection data and lens geometric parameter data to be assembled, and to synchronize the standardized detection data to the other modules.

[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] Example 1: Please refer to Figures 1-11 As shown, this embodiment is a fully automatic optical lens assembly and pre-tension force adaptive control device and system. The assembly base 1 is connected to the production line for transporting optical lens components. It should be noted that the assembly base 1 is suitable for installation in the inner corner area of ​​the L-shaped production line. It is connected to the bottom support of the optical lens sleeve conveying production line by the limiting side frame 102, and the locking frame 103 is in contact with the support for limiting. It is locked and fixed by bolts. The optical lens assembly is completed and the output production line is erected at the bottom of the other side of the rotating clamping tray frame 2. As for the stacked lenses of different models and thicknesses, they are connected to each set of feeding holes 301 on the lens feeding tray frame 3 by the corresponding lens conveying equipment. This is used to transport the corresponding lenses to the designated position, and to cooperate with the optical feeding frame 4 to pick up the lenses and put them one by one into the clamping sleeve 6 for assembly.

[0022] When one set of lens sleeves is conveyed close to one end of the rotating clamping tray 2 and aligned vertically with the current set of clamping sleeves 6, the vertical telescopic cylinder 601 drives the clamping sleeve 6 to slide down along the inside of the perforation until the lens sleeve is completely fitted and covered. The annular cylinder 603 drives the swing arm 605 to move through the connecting shaft 604. The swing arm 605 is deflected with the limiting slide shaft 606 as the fulcrum. The swing arm 605 has an arc-shaped groove through its middle. Therefore, the swing arm 605 is deflected with the limiting slide shaft 606 as the fulcrum. 606 slides into contact with the arc-shaped groove, causing the adapter clamp 602 to move towards the center. Through the connecting hinge between the adapter clamp 602 and the swing arm 605, the adapter clamp 602 contacts the outer wall of the lens sleeve. With the cooperation of multiple sets of adapter clamps 602, the lens sleeve is limited and clamped in the center position inside the sleeve 6, thereby avoiding positional deviation of the lens sleeve. It should be noted that the adapter clamp 602 is replaced in advance according to different models of lens sleeves to fit the corresponding model of lens sleeve.

[0023] After the lens sleeve is clamped and limited, the vertical telescopic cylinder 601 drives the clamping sleeve 6 to slide up and reset to the inside of the perforation. The drive motor 104 drives the transmission sleeve shaft 201 through gears and transmission shaft. The transmission sleeve shaft 201 drives the rotating clamping plate 2 to rotate a certain angle until the lens sleeve is moved directly above the bottom telescopic inspection frame 5, at which point the rotation and movement are paused.

[0024] The bottom telescopic inspection frame 5 drives the inspection cylinder 501 to slide upwards until the top of the inspection cylinder 501 approaches or extends to the bottom of the lens sleeve. The inner cylinder 502 then drives the inner support rod 505 to slide further upwards, moving the laser receiver 509 and the inspection arm 506 above the area inside the lens sleeve for lens mounting. The swing cylinder 508 drives the inspection arm 506 to rotate and unfold, sequentially unfolding the inspection arm 506 to corresponding angles. The inner cylinder 502 then drives the inner support rod 505 to slide down a short distance until the inspection ball 507 on the inspection arm 506 contacts the corresponding lens slot. The inner rotating cylinder 504 then drives the inner support rod 505 and the laser receiver 509 to slide upwards. The receiver 509 and the detection arm 506 rotate synchronously to perform circular movement detection on the inner wall of the lens slot being inspected, thereby determining whether there are foreign objects or defects on the inner wall of the current set of lens slots. The data generated by the pressure sensor or other types of sensors installed inside the detection ball 507 is used to make judgments and is displayed on the display screen of the control terminal. The relevant data log is recorded and archived. The detection data is performed one by one on several sets of lens slots inside the lens sleeve, and the detection data is matched with the size of the corresponding lenses in the corresponding sequence on the lens conveying production line to determine in advance whether the currently sorted lens fits the corresponding lens slot of the lens sleeve.

[0025] During the lens slot inspection, the telescopic cylinder arm 402 drives the telescopic adjustment arm 403 to move to the center of the feeding hole 301. Based on the lens slot being inspected by the current inspection arm 506, the micro cylinder drives the support slide rod to slide along the surface of the verification telescopic thin rod 407, thereby driving the support thin rod 411 to adjust the unfolding angle of the support bone 409 on the hinge seat 408. This causes the light-shielding cloth to form a light-shielding area of ​​the same size as the lens slot above the clamping sleeve 6. Accompanied by the rotation of the inner support rod 505, the laser receiver 509 adjusts the pre-existing light according to the currently inspected lens slot. The dimensions are unfolded, and the laser measuring lamp 405 is activated to generate a vertical laser beam that irradiates the inside of the lens sleeve. The laser detector receives the laser irradiation range in the area above the lens slot, thereby generating feedback data and producing and storing test logs. Based on the test logs, a vertical comparison is made with the currently matched lens size to construct a multi-compatibility test of the lens and lens slot. This avoids edge assembly friction caused by mismatch between the lens and lens slot, as well as excessive pre-tightening force after the lens and lens slot are assembled, which could lead to adverse reactions during use after the optical lens is assembled.

[0026] After the current lens sleeve is inspected and processed, the drive motor 104 further drives the rotating clamping tray 2 to rotate and move its angle until the current lens sleeve is moved directly below the optical feeding rack 4 where lenses are waiting to be placed. The optical feeding rack 4 adjusts its height via the built-in lifting cylinder 401 driving the telescopic cylinder arm 402, causing the feeding suction cup 404 to be positioned above the lens conveying equipment. The telescopic cylinder arm 402 moves the feeding suction cup 404 above the lens conveying equipment. The telescopic adjustment arm 403 then moves the feeding suction cup 404 to move the lens from the center of the lens conveying equipment. The lens is picked up by adsorption. The telescopic adjustment arm 403 vertically drives the adsorbed lens to slide upward. The telescopic cylinder arm 402 resets and drives the adsorbed lens back to the center of the optical feeding rack 4. The built-in lifting cylinder 401 drives the adsorbed lens to slide down until it is placed in the corresponding lens slot inside the lens sleeve, completing the assembly of a single lens. The rotation and feeding assembly are carried out in sequence until all lenses in the lens sleeve are assembled. Then, the rotating clamping tray 2 is used to put the lens onto the external production line and transport it to the next step to complete the subsequent processing.

[0027] In Example 2, the control system includes a data acquisition module, a light source detection and analysis module, a dynamic contact detection and analysis module, a preload prediction and analysis module, a comprehensive judgment module, an instruction generation and execution module, and a data storage and log module. These modules work collaboratively to detect the fit between the lens slot and the lens, predict the preload, and control assembly instructions. This control system is deeply coupled with the mechanical actuator of the device. Through a logical process of multi-dimensional data acquisition, hierarchical analysis and processing, precise preload prediction, and intelligent instruction generation, it achieves multiple detections of the fit between the lens slot and the lens, predicts in advance any defects caused by abnormal preload after assembly, and provides precise action instructions to the mechanical actuator, ensuring the automation and accuracy of optical lens assembly.

[0028] This control system adopts a modular distributed architecture. Each module establishes real-time communication with the sensors, drive motors 104, cylinders, and other components of the mechanical actuators via an industrial bus. The data acquisition module serves as the data entry point, standardizing various detection data and synchronizing it to each analysis module. After three layers of analysis—light source detection, dynamic contact detection, and preload prediction—the comprehensive judgment module outputs the final adaptability result. The instruction generation and execution module drives the mechanical mechanism to move according to the result. The data storage and log module completes the data archiving and benchmark calibration of the entire process. The overall architecture ensures the real-time performance and continuity of detection, analysis, and execution. It precisely coordinates with the rotation of the rotating clamping plate 2, the lifting of the bottom telescopic detection frame 5, and the feeding of materials by the optical feeding frame 4 to achieve integrated control of detection, prediction, and assembly.

[0029] The data acquisition module is used to establish data interaction with the sensors of the bottom telescopic detection frame 5, laser measuring lamp 405, laser receiver 509, and detection ball 507, as well as the parameter acquisition unit of the lens conveying equipment. It collects and standardizes the geometric parameter data of the lens slot, dynamic contact pressure data, laser adapter detection data, and geometric parameter data of the lens to be assembled, and synchronizes the standardized detection data to the other modules. Laser adapter testing data includes the inner diameter of the card slot. Card slot depth Roundness of the inner wall of the card slot Card slot coaxiality The data is obtained jointly by the rotation detection of the detection ball and the contour detection of the laser receiver; The dynamic contact pressure data includes the contact pressure Pᵢ between the detection ball and the inner wall of the slot, and the contact displacement Sᵢ of the detection ball, which are collected by the pressure sensor and displacement sensor inside the detection ball, i=1,2,3......n, where n is the number of detection points; Laser compatibility testing data includes the radius of the laser lamp's illumination range. Radius of the effective irradiation range of the slot received by the laser receiver Radius of the effective blocking range of the lens The data is collected by the photoelectric sensor of the laser measuring lamp and the laser receiver; Geometric parameters of the lens to be assembled include the lens outer diameter. Lens thickness Lens edge roundness The data is collected by the visual inspection and size inspection unit of the lens delivery equipment.

[0030] The collected raw data were standardized in terms of dimensions and outliers were removed. The standard units were adopted for dimension standardization, and the 3σ principle was adopted for outlier removal, that is, the detection data that exceeded the range of μ±3σ were removed, where μ is the data mean and σ is the data standard deviation, so as to avoid the subsequent analysis bias caused by sensor error.

[0031] The light source detection and analysis module, based on the linear propagation characteristics of laser, analyzes the compatibility of the laser irradiation range with the geometric dimensions of the slot and lens in the radial dimension. By measuring the difference in radial dimensions between the slot and lens detected by the laser, the laser compatibility is quantified, according to the formula... ,in, The value range is 0-1. The closer the value is to 1, the better the radial fit between the two. =1 indicates that the radial dimensions of the two are perfectly matched. This is represented as the radius of the effective irradiation range of the card slot; This is expressed as the radius of the effective blocking range of the lens; Indicated as the inner diameter of the slot; Indicated as the outer diameter of the lens; Represented as and The maximum value in the range is used to normalize the difference and eliminate the influence of dimensions. like ≥ The laser is deemed suitable, and the output result is "Light source detection passed". like < If the laser is deemed unsuitable, the output result will be "Light source detection failed," and the dimension parameter with the largest deviation will be marked.

[0032] The dynamic contact detection and analysis module detects the dynamic contact between the detection ball and the inner wall of the slot, completing the structural integrity detection and mechanical contact fit calculation of the slot. It analyzes the smoothness of assembly from two dimensions: the slot's own structure and the mechanical contact between the two. The acceptable threshold for mechanical contact fit is set as follows: ≥0.9; contact pressure in dynamic contact detection data Perform analysis and calculate the average pressure. According to the formula If the pressure at any detection point Exceeding the preset contact pressure threshold, the preset contact pressure threshold is: , or pressure variance If too large, retrieve the preset variance threshold. If the card slot is found to have structural defects such as foreign objects, dents, or protrusions on its inner wall, the mechanical contact test will fail and the card slot structure will be deemed abnormal.

[0033] If the integrity test of the card slot structure is passed, the mechanical contact fit is calculated based on the geometric parameters of the card slot and the lens. According to the formula The mechanical contact compatibility between the slot and the lens is quantified by the difference in their axial dimensions and edge roundness. The value range is 0-1. The closer it is to 1, the better the axial contact and edge matching between the two, and the smoother the assembly process. This is expressed as the card slot depth; This is expressed as lens thickness; This refers to the roundness of the inner wall of the card slot; This refers to the roundness of the lens edge; Represented as and The maximum value in the range is used for normalization. like ≥ The machine is deemed mechanically compatible and passes the mechanical contact test. like < The result was determined to be a mechanical contact mismatch, with the output mechanical contact test failing and dimensional mismatch occurring.

[0034] The preload prediction and analysis module, based on the fit results and geometric parameter data from the preceding module, predicts the static preload F after the lens and slot are assembled. It proactively identifies issues of excessive or insufficient preload due to compatibility problems. Excessive preload can cause lens deformation, while insufficient preload can lead to lens loosening, both resulting in optical lens defects. A preset safe preload threshold is [value missing]. .

[0035] This embodiment uses the elastic contact preload formula to calculate the predicted value F. This formula is applicable to interference fit assembly scenarios where optical lens elements and metal / plastic card slots are assembled. According to the formula... ,in, This represents the combined elastic modulus of the slot and the lens, calculated using a mixed elastic modulus. , Expressed as the elastic modulus of the slot material. Expressed as the elastic modulus of the lens material; This is expressed as the interference fit between the slot and the lens. ,like A negative value indicates a clearance fit, and the preload is approximately zero. Indicated as the inner diameter of the slot; This represents the radius of the laser beam's illumination range, which is the basic data for laser adaptation detection directly acquired by the data acquisition module. Expressed as Poisson's ratio, it is the average Poisson's ratio of the slot and the lens. ; This refers to the inner diameter of the lens. If it is a non-porous lens, =0; like Located at the safety threshold The preload is deemed qualified, and the output preload preload is pre-judged as qualified. like > The result is that the preload is too high, the output preload prediction fails, and the interference is too large. like < , including A clearance fit of ≤0 is judged as insufficient preload, resulting in failure to pass the output preload prediction, insufficient interference, or clearance fit.

[0036] The comprehensive judgment module establishes a tiered comprehensive judgment rule, which comprehensively evaluates the results of light source detection, mechanical contact detection, and preload pre-judgment. The rules have no priority stacking; only when all detection items are passed can the assembly be judged as qualified. The specific judgment rules are as follows: If the light source detection passes, the mechanical contact detection passes, and the pre-tightening force prediction passes, the assembly is deemed suitable and qualified, and the overall output result is "Assembleable". If the light source test fails, the mechanical contact test fails, or the preload pre-judgment fails, the assembly adaptation is deemed unqualified, and the specific reasons for the failure are output: preload pre-judgment fails, interference fit is too large, mechanical contact test fails, or the slot structure is abnormal. If sensor malfunctions or data acquisition interruptions occur during the testing process, the overall assessment will be considered as a testing anomaly, and the output will indicate that assembly is paused or the testing equipment is malfunctioning.

[0037] Based on the overall result from the comprehensive judgment module, the instruction generation and execution module generates three types of control instructions and sends them to the corresponding mechanical actuators via the industrial bus. The instructions and mechanical actions are precisely linked. The specific instruction types and execution logic are as follows: Lens assembly instruction: If the overall judgment result is that it can be assembled, this instruction is generated and sent to the actuators of the optical feeding frame 4 and the rotating clamping tray frame 2 to control the feeding suction cup 404 of the optical feeding frame 4 to complete the lens adsorption and feeding, and accurately place the lens in the lens slot to complete the assembly of a single lens. Lens / slot replacement instruction: If the overall judgment result is that the assembly and adaptation is unqualified, or the size matching deviation / interference is abnormal, this instruction is generated and sent to the actuator of the lens conveying equipment and the rotary clamping tray 2 to control the lens conveying equipment to replace the lens of the corresponding specification, or to control the rotary clamping tray 2 to transfer the lens sleeve of the unqualified slot to the defective product area and replace it with a new lens sleeve. Assembly failure judgment instruction: If the comprehensive judgment result is assembly mismatch, abnormal slot structure or detection abnormality, this instruction is generated and sent to the actuator of the entire device to control the rotating clamping tray 2 to stop rotating and transfer the lens sleeve to the non-conforming product area. At the same time, if it is a detection abnormality, the equipment alarm is triggered to prompt the staff to repair the sensor.

[0038] The data storage and log module stores the standardized test data, analysis results, judgment results, instruction types and execution results in a structured manner, and establishes a unique index according to the lens sleeve number, test time, card slot number and lens number to ensure data traceability. Generate a test assembly log to record the deviation parameters, prediction results, and instruction execution status for each test. The log format is a fixed table containing fields such as timestamp, device number, data item, test value, threshold, judgment result, instruction type, and execution status. Statistical analysis of historical test pass data is used to update the preset thresholds of the control system, providing a dynamic benchmark for subsequent equipment initialization and parameter calibration, thereby improving the accuracy of detection and prediction. The preset thresholds include... , , .

[0039] The rotating clamping tray 2 moves the lens sleeve to the top of the bottom telescopic detection frame 5 and pauses. The control system triggers equipment initialization and calibrates the reference positions of the detection ball 507 and the laser receiver 509. The bottom telescopic detection frame 5 drives the detection cylinder rod 501 to slide upward, the detection ball 507 enters the slot, the data acquisition module starts to collect the slot geometric parameter data and dynamic contact detection data, the laser measuring lamp 405 is activated, and the laser adapter detection data is collected. Each analysis module processes data synchronously, sequentially completing light source detection, dynamic contact detection, and pre-tightening force prediction. The comprehensive judgment module outputs an assembly result. The instruction generation and execution module issues an assembly instruction, and the rotating clamping tray 2 moves the lens sleeve to the bottom of the optical feeding rack 4. The feeding suction cup 404 of the optical feeding rack 4 adsorbs the corresponding lens and accurately places it into the slot, completing the assembly. The data storage and log module records all data and assembly results from this test and synchronizes them to the benchmark parameter library; The rotating clamping tray 2 transfers the assembled lens sleeves to the outgoing production line, and the control system enters the next set of lens sleeves for inspection and assembly.

[0040] Combining Embodiments 1 and 2, the control system is deeply integrated with the mechanical structure of the fully automated assembly and pre-tension force adaptive control device for optical lenses. Through multiple detection dimensions, it achieves comprehensive fit analysis between the lens slot and the lens, and uses mathematical models to accurately predict the pre-tension force, identifying potential defects after assembly in advance. This avoids problems such as lens deformation and loosening caused by dimensional deviations in traditional assembly processes. Simultaneously, the modular design and intelligent command generation of the control system achieve automation and integration of detection and assembly, eliminating the need for manual intervention and improving the assembly efficiency and yield rate of optical lenses. Furthermore, the full-process data acquisition and archiving provides data support for production traceability and process optimization of optical lenses, adapting to large-scale industrial production scenarios.
