[0003] With the rapid development of optical technology, the requirements for lens performance are increasing day by day. Performance detection and evaluation during the production process of optical lenses are essential steps. However, it is currently difficult to comprehensively detect and comprehensively evaluate the performance of optical lenses, and it is impossible to strengthen production control in a timely manner based on the production performance and sales performance of optical lenses, increasing the difficulty of optical lens production management and having a low degree of intelligence.

[0004] In view of the above technical deficiencies, a solution is now proposed. Summary of the Invention

[0006] To achieve the above purpose, the present invention provides the following technical solution:

[0007] A performance evaluation system adapted to the production of optical lenses includes an item-by-item optical lens testing module, an optical lens performance evaluation module, a seamless production docking module, an optical lens sales traceability module, and a supervision terminal; the item-by-item optical lens testing module tests the various performances of the optical lens, obtains the test analysis results of the various performances, and sends the test data of the various performances to the optical lens performance evaluation module.

[0008] The optical lens performance evaluation module receives the test data of the various performances of the optical lens and makes performance judgments. If the test data of the various performances of the optical lens all meet the requirements, the corresponding optical lens is marked as a non-abnormal lens. If there are performances that do not meet the requirements in the optical lens, the corresponding optical lens is marked as a lens to be optimized, and the marking information and the judgment information of the various performances of the optical lens are sent to the supervision terminal.

[0009] The production seamless docking module obtains the model of the corresponding optical lens, analyzes the production quality status of the corresponding model of optical lens produced during the monitoring period, generates a production anomaly signal or a production qualified signal through the analysis, sends the production anomaly signal to the supervision terminal, and sends the production qualified signal to the optical lens sales traceability module;

[0010] When the optical lens sales traceability module receives the production qualified signal, it comprehensively analyzes the sales status of the corresponding model of optical lens during the monitoring period, generates a sales anomaly signal or a sales qualified signal through the analysis, and sends the sales anomaly signal to the supervision terminal; when the supervision terminal receives the production anomaly signal or the sales anomaly signal, it issues a corresponding warning.

[0011] Furthermore, the test items of the optical lens item-by-item test module for the optical lens include resolution test, sharpness test, contrast test, distortion test, chromatic aberration test, focal length test, aperture test, light transmittance test, focusing accuracy test, and focusing speed test.

[0012] Furthermore, in the resolution test, the optical lens is imaged and detected through a high-resolution test chart or a specific resolution test pattern, and the minimum line width or the number of line pairs that can be distinguished in the image is photographed and analyzed; in the sharpness test, the optical lens photographs the edge sharpness test chart, and is evaluated by analyzing the width of the transition region or the sharpness index of the image edge;

[0013] In the contrast test, the optical lens is imaged and detected using test images with different contrast levels, and the brightness difference between the brightest and darkest parts of the image is measured and recorded; in the distortion test, the optical lens photographs a test image with a standard geometric shape, and the degree of deformation of the geometric shape in the image is analyzed and recorded; in the chromatic aberration test, the optical lens is imaged and detected using a test image containing multiple colors, and it is observed and recorded whether the edges of different color regions in the image are clear and aligned;

[0014] In the focal length test, by adjusting the focal length of the optical lens and photographing a standard test image, the magnification of the image at different focal lengths is recorded; in the aperture test, the light input amount of the optical lens at different aperture values, as well as the corresponding depth of field and picture brightness, are measured and recorded; in the light transmittance test, using a light source and a light intensity meter, the light transmittance of the optical lens at different wavelengths is measured and recorded;

[0015] In the focusing accuracy test, the optical lens photographs a standard focusing test image, and the difference between the clarity of the image after the optical lens is focused and the expected clarity is measured and recorded; in the focusing speed test, a timer is used to record the time required for the optical lens to complete focusing from the initial position.

[0016] Furthermore, the specific analysis process of the production seamless docking module includes:

[0017] Obtain the quantity of optical lenses of the corresponding model produced and performance - tested and evaluated during the monitoring period, and mark it as the prenatal inspection value of the optical lens. Mark the quantity of the lenses to be optimized among them as the value of lenses to be optimized. Calculate the ratio of the value of lenses to be optimized to the prenatal inspection value of the optical lens to obtain the lens production characteristic value. Compare the lens production characteristic value with the preset lens production characteristic threshold value. If the lens production characteristic value exceeds the preset lens production characteristic threshold value, generate a production anomaly signal.

[0018] Furthermore, if the lens production characteristic value does not exceed the preset lens production characteristic threshold value, obtain the performance information that does not meet the requirements involved in the corresponding lenses to be optimized, and mark the performance that does not meet the requirements as the negative feedback object.

[0019] Obtain the quantity of optical lenses whose corresponding performance is marked as the negative feedback object during the monitoring period, and calculate the ratio of this quantity to the prenatal inspection value of the optical lens to obtain the negative feedback ratio. And preset a set of preset quality influence weight values for each performance respectively. Multiply the negative feedback ratio of the corresponding performance by the corresponding preset quality influence weight value to obtain the negative influence coefficient.

[0020] Obtain the negative influence coefficients of all performances and sum them up to calculate the lens production performance value. Compare the lens production performance value with the preset lens production performance threshold value. If the lens production performance value exceeds the preset lens production performance threshold value, generate a production anomaly signal; if the lens production performance value does not exceed the preset lens production performance threshold value, generate a production qualified signal.

[0021] Furthermore, the specific analysis process of the optical lens sales traceability module includes:

[0022] Obtain the sales quantity of the corresponding model of optical lenses sold during the monitoring period, and mark the ratio of this quantity to the set standard sales quantity as the optical lens sales value. And collect the number of returns and exchanges of the corresponding model of optical lenses due to quality problems during the monitoring period, and mark it as the optical lens return value to the factory.

[0023] And obtain all sales evaluation information for the corresponding optical lenses during the monitoring period. Mark the number of negative reviews regarding performance in the sales evaluation information as the performance word - of - mouth anomaly value.

[0024] Numerically compare the optical lens traceability value with the preset optical lens traceability threshold. If the optical lens traceability value exceeds the preset optical lens traceability threshold, generate a sales anomaly signal for the corresponding model of the optical lens; if the optical lens traceability value does not exceed the preset optical lens traceability threshold, generate a sales qualification signal for the corresponding model of the optical lens.

[0025] Furthermore, the supervision terminal is communicatively connected to the optical lens test monitoring module and the test precision classification module. The optical lens test monitoring module is used to monitor the test process of the optical lens and send the monitoring information to the test precision classification module; the test precision classification module analyzes the test performances for various performances during the monitoring period, marks the corresponding performances as test-easy-to-control performances or test-difficult-to-control performances through the analysis, and sends the marking information of each performance to the supervision terminal.

[0026] Furthermore, the specific analysis process of marking the corresponding performance as a test-easy-to-control performance or a test-difficult-to-control performance through analysis is as follows:

[0027] Obtain all the performances for testing the corresponding model of the optical lens, mark the corresponding performance as the target object i, and i is a natural number greater than 1; at the end of the test of the target object i for the corresponding optical lens, collect the test operation duration and the error operation frequency of the corresponding test process, and numerically compare the test operation duration and the error operation frequency with the corresponding preset test operation duration threshold and the preset error operation frequency threshold respectively. If the test operation duration or the error operation frequency exceeds the corresponding preset threshold, mark the corresponding test process for the target object i as an abnormal test process;

[0028] Obtain the ratio of the number of abnormal test processes corresponding to the target object i during the monitoring period and mark it as the abnormal test matching value. Numerically compare the abnormal test matching value with the preset abnormal test matching threshold. If the abnormal test matching value exceeds the preset abnormal test matching threshold, mark the target object i as a test-difficult-to-control performance.

[0029] Furthermore, if the abnormal test matching value does not exceed the preset abnormal test matching threshold, mark the ratio of the test operation duration to the corresponding preset test operation duration threshold as the test operation time detection value, and mark the ratio of the error operation frequency to the corresponding preset error operation frequency threshold as the test error detection value;

[0030] Obtain all the test operation time detection values of the target object i during the monitoring period and calculate their mean value to obtain the test efficiency analysis value, and calculate the mean value of all the test error detection values of the target object i to obtain the test error analysis value. Calculate the control evaluation coefficient through numerical calculation of the abnormal test matching value, the test efficiency analysis value, and the test error analysis value;

[0031] Compare the control evaluation coefficient with the preset control evaluation coefficient threshold. If the control evaluation coefficient exceeds the preset control evaluation coefficient threshold, mark the target object i as difficult to control in testing; if the control evaluation coefficient does not exceed the preset control evaluation coefficient threshold, mark the target object i as easy to control in testing.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment 1: As Figure 1As shown in the figure, the performance evaluation system proposed by the present invention for optical lens production includes an item-by-item optical lens testing module, an optical lens performance evaluation module, a production seamless docking module, an optical lens sales traceability module, and a supervision terminal; the item-by-item optical lens testing module tests the various performances of the optical lens, obtains the test analysis results of the various performances, and sends the test data of the various performances to the optical lens performance evaluation module to achieve a comprehensive test of the optical lens, provide data support for the evaluation process of the optical lens performance evaluation module, and ensure the accuracy of its analysis results;

[0040] It should be noted that the test items of the item-by-item optical lens testing module for the optical lens include resolution test, sharpness test, contrast test, distortion test, chromatic aberration test, focal length test, aperture test, light transmittance test, focusing accuracy test, and focusing speed test.

[0041] Resolution refers to the ability of the lens to distinguish object details, usually expressed in lines per millimeter (lp / mm). In the resolution test, the optical lens is imaged and detected through a high-resolution test chart or a specific resolution test pattern, and the minimum line width or the number of line pairs that can be distinguished in the image is photographed and analyzed;

[0042] Sharpness refers to the clarity and edge sharpness of the lens imaging. In the sharpness test, the optical lens takes a standard test image, such as an edge sharpness test chart, and is evaluated by analyzing the width of the transition region or the sharpness index of the image edge;

[0043] Contrast refers to the light and dark contrast of the lens imaging. In the contrast test, test images with different contrast levels are used to image and detect the optical lens, and the brightness difference between the brightest and darkest parts of the image is measured and recorded;

[0044] Distortion refers to the geometric deformation generated during the lens imaging, which is divided into barrel distortion and pincushion distortion; in the distortion test, the optical lens takes a test image with a standard geometric shape (such as a grid or a dot array), and the degree of deformation of the geometric shape in the image is analyzed and recorded;

[0045] Chromatic aberration refers to the different refraction degrees of the lens for light of different wavelengths, resulting in color aberration in the imaging; in the chromatic aberration test, test images containing multiple colors are used to image and detect the optical lens, and it is observed and recorded whether the edges of different color regions in the image are clear and aligned;

[0046] Focal length refers to the distance at which the lens images an object on the photosensitive element, reflecting the magnification of the lens; in the focal length test, the focal length of the optical lens is adjusted and a standard test image is taken, and the magnification of the image at different focal lengths is recorded;

[0047] The aperture refers to the size of the aperture through which the lens beam passes, expressed by the f value; in the aperture test, the light intake of the optical lens at different aperture values, as well as the corresponding depth of field and picture brightness, are measured and recorded; in the light transmittance test, a light source and a light intensity measuring instrument are used to measure and record the light transmittance of the optical lens at different wavelengths.

[0048] The focusing accuracy refers to the accuracy of the lens focusing. In the focusing accuracy test, the optical lens takes pictures of the standard focusing test image, and measures and records the difference between the clarity of the image after the optical lens focuses and the expected clarity; the focusing speed refers to the time required for the lens to focus. In the focusing speed test, a timer is used to record the time required for the optical lens to complete focusing from the initial position.

[0049] The optical lens performance evaluation module receives the test data of various performances of the optical lens and makes performance judgments. If the test data of various performances of the optical lens all meet the requirements, the corresponding optical lens is marked as a lens without abnormality. If there are performances that do not meet the requirements in the optical lens, the corresponding optical lens is marked as a lens to be optimized, and the marking information of the optical lens and the judgment information of various performances are sent to the supervision terminal, so that the supervision personnel can master in detail the quality status of each produced optical lens and make reasonable disposal measures for each optical lens, thereby ensuring the quality of the optical lenses leaving the factory.

[0050] The production seamless docking module obtains the model of the corresponding optical lens, analyzes the production quality status of the optical lenses of the corresponding model produced during the monitoring period, generates a production abnormal signal or a production qualified signal through the analysis, and sends the production abnormal signal to the supervision terminal;

[0051] When the supervision terminal receives the production abnormal signal, it issues a corresponding warning, can reasonably analyze the production performance of the optical lenses of the corresponding model during the monitoring period and give a timely warning, which is conducive to the supervision personnel to strengthen the subsequent production supervision in time and ensure the quality of the produced optical lenses; the specific analysis process of the production seamless docking module is as follows:

[0052] Obtain the number of optical lenses of the corresponding model produced and subjected to performance test and evaluation during the monitoring period and mark it as the optical lens prenatal inspection value, and mark the number of lenses to be optimized among them as the optical lens to-be-optimized value. Calculate the ratio of the optical lens to-be-optimized value to the optical lens prenatal inspection value to obtain the lens production characteristic value. Compare the lens production characteristic value with the preset lens production characteristic threshold. If the lens production characteristic value exceeds the preset lens production characteristic threshold, it indicates that the production performance of the optical lenses of the corresponding model produced during the monitoring period is poor, and a production abnormal signal is generated;

[0053] If the lens production eigenvalue does not exceed the preset lens production feature threshold, the performance information that does not meet the requirements for the corresponding lens to be optimized is obtained, and the performance that does not meet the requirements is marked as the negative feedback object;

[0054] The number of optical lenses whose corresponding performance is marked as the negative feedback object during the monitoring period is obtained and the ratio is calculated with the prenatal inspection value of the optical lens to obtain the negative feedback ratio. Moreover, a set of preset quality impact weight values is set for each performance in advance. The values of all preset quality impact weight values are positive numbers. And the greater the impact of the corresponding performance on the quality of the optical lens, the greater the value of the preset quality impact weight value matched with it;

[0055] The negative feedback ratio of the corresponding performance is multiplied by the corresponding preset quality impact weight value to obtain the negative impact coefficient; the negative impact coefficients of all performances are obtained and summed to calculate the lens production performance value. The lens production performance value is numerically compared with the preset lens production performance threshold. If the lens production performance value exceeds the preset lens production performance threshold, it indicates that the production performance of the corresponding type of optical lens produced during the monitoring period is poor, and a production anomaly signal is generated; if the lens production performance value does not exceed the preset lens production performance threshold, it indicates that the production performance of the corresponding type of optical lens produced during the monitoring period is good, and a production qualified signal is generated.

[0056] Furthermore, the production seamless docking module sends the production qualified signal to the optical lens sales traceability module. When the optical lens sales traceability module receives the production qualified signal, it comprehensively analyzes the sales status of the corresponding type of optical lens during the monitoring period, generates a sales anomaly signal or a sales qualified signal through the analysis, and sends the sales anomaly signal to the supervision terminal. When the supervision terminal receives the sales anomaly signal, it issues a corresponding warning to remind the supervision personnel to strengthen the production control of the corresponding type of optical lens in a timely manner, further ensuring the quality of the optical lens leaving the factory, thereby enhancing the reputation and sales performance of the corresponding type of optical lens; the specific analysis process of the optical lens sales traceability module is as follows:

[0057] The sales quantity of the corresponding type of optical lens sold during the monitoring period is obtained and the ratio with the set standard sales quantity is marked as the optical lens sales value, and the number of returns and exchanges due to quality problems of the corresponding type of optical lens during the monitoring period is collected and marked as the optical lens return value; and all sales evaluation information for the corresponding optical lens during the monitoring period is obtained, and the number of negative reviews regarding performance in the sales evaluation information is marked as the performance reputation anomaly value;

[0058] The optical lens sales value X, the optical lens return value F, and the performance reputation outlier Y are numerically calculated through the formula W = (t×F + n×Y) / (q×X + 1) to obtain the optical lens traceability value W; where q, t, and n are preset proportionality coefficients greater than zero, and the larger the value of the optical lens traceability value W, the worse the comprehensive sales performance of the corresponding model of optical lens during the monitoring period;

[0059] The optical lens traceability value W is numerically compared with the preset optical lens traceability threshold. If the optical lens traceability value W exceeds the preset optical lens traceability threshold, indicating that the comprehensive sales performance of the corresponding model of optical lens during the monitoring period is poor, then a sales anomaly signal for the corresponding model of optical lens is generated; if the optical lens traceability value W does not exceed the preset optical lens traceability threshold, indicating that the comprehensive sales performance of the corresponding model of optical lens during the monitoring period is good, then a sales qualified signal for the corresponding model of optical lens is generated.

[0060] Embodiment 2: As Figure 2 shown, the difference between this embodiment and Embodiment 1 is that the supervision terminal is communicatively connected to the optical lens test monitoring module and the test precision classification module. The optical lens test monitoring module is used to monitor the test process of the optical lens and send the monitoring information to the test precision classification module and the supervision terminal, which can not only provide information support for the analysis process of the test precision classification module, but also help the supervision personnel to detailedly master the performance information of each test process;

[0061] The test precision classification module analyzes the test performances of various performances during the monitoring period, marks the corresponding performances as test-easy-to-control performances or test-difficult-to-control performances through the analysis, and sends the marking information of each performance to the supervision terminal, which is beneficial to the targeted formulation of subsequent training and management plans, and strengthens the test training and test supervision of the test personnel on the test-difficult-to-master performances in the subsequent process to ensure the test efficiency and test accuracy of the subsequent tests for each performance; the specific analysis process is as follows:

[0062] All performances for testing the corresponding model of optical lens are obtained, and the corresponding performance is marked as the target object i, and i is a natural number greater than 1; at the end of the test of the target object i for the corresponding optical lens, the test operation duration (i.e., the interval duration between the test start time and the end time) and the wrong operation frequency (i.e., the number of times the operator makes mistakes during the corresponding test process) of the corresponding test process are collected;

[0063] Numerically compare the test operation duration and the incorrect operation frequency with the corresponding preset test operation duration threshold and the preset incorrect operation frequency threshold respectively. If the test operation duration or the incorrect operation frequency exceeds the corresponding preset threshold, it indicates that the test performance of the corresponding test process for the target object i is poor, and then mark the corresponding test process for the target object i as an abnormal test process;

[0064] Obtain the ratio of the number of abnormal test processes corresponding to the target object i during the monitoring period and mark it as the abnormal test matching value. Numerically compare the abnormal test matching value with the preset abnormal test matching threshold. If the abnormal test matching value exceeds the preset abnormal test matching threshold, it indicates that the test operation difficulty for the target object i during the monitoring period is relatively large, and then mark the target object i as having difficult-to-control test performance.

[0065] Furthermore, if the abnormal test matching value does not exceed the preset abnormal test matching threshold, then mark the ratio of the test operation duration to the corresponding preset test operation duration threshold as the test operation time detection value, and mark the ratio of the incorrect operation frequency to the corresponding preset incorrect operation frequency threshold as the test misdetection value;

[0066] Obtain all the test operation time detection values of the target object i during the monitoring period and calculate their mean value to obtain the test efficiency analysis value, and calculate the mean value of all the test misdetection values of the target object i to obtain the test error analysis value; Numerically calculate the abnormal test matching value Qi, the test efficiency analysis value Mi, and the test error analysis value Si through the formula HLi = u×Qi + g×Mi + e×Si to obtain the control evaluation coefficient HLi; where u, g, e are preset weight coefficients greater than zero, and moreover, the larger the value of the control evaluation coefficient HLi, the greater the comprehensive test operation difficulty for the target object i during the monitoring period;

[0067] Numerically compare the control evaluation coefficient HLi with the preset control evaluation coefficient threshold. If the control evaluation coefficient HLi exceeds the preset control evaluation coefficient threshold, it indicates that the comprehensive test operation difficulty for the target object i during the monitoring period is relatively large, and then mark the target object i as having difficult-to-control test performance; if the control evaluation coefficient HLi does not exceed the preset control evaluation coefficient threshold, it indicates that the comprehensive test operation difficulty for the target object i during the monitoring period is relatively small, and then mark the target object i as having easy-to-control test performance.

[0068] Working principle of the present invention: During use, various performance tests of the optical lens are carried out by the item-by-item test module of the optical lens. The optical lens performance evaluation module receives the test data of various performances of the optical lens and makes a performance judgment to determine normal lenses and lenses to be optimized, which facilitates taking reasonable disposal measures for each optical lens, ensuring the quality of the optical lenses leaving the factory. Moreover, the production seamless docking module analyzes the production quality status of the optical lenses of the corresponding model produced during the monitoring period. When a production qualified signal is generated, the optical lens sales traceability module comprehensively analyzes the sales status of the optical lenses of the corresponding model during the monitoring period. When a production abnormal signal or a sales abnormal signal is generated, the production control of the optical lenses of the corresponding model is strengthened, further ensuring the quality of the optical lenses leaving the factory, significantly reducing the management difficulty of the supervisors, and having a high degree of intelligence.
