Description

Technical Field

[0001] The present application relates to the field of image processing technology, and in particular to a method, device, equipment and medium for detecting a light-transmitting power generation glass film layer. Background Art

[0002] Transparent power generation glass is a special material that integrates glass and photovoltaic power generation technology. It can ensure high light transmittance and high power generation efficiency at the same time. It is widely used in construction, automobiles, agriculture, aviation and other fields. The light energy conversion efficiency is above 7%, reaching the international leading level1. Cadmium telluride power generation glass with different transmittance is suitable for different photovoltaic application scenarios. For example, power generation glass without light transmittance requirements is suitable for scenarios with strict waterproof requirements, 20% transmittance power generation glass is suitable for scenarios that need to take into account lighting, heat insulation and power generation, and 40% transmittance power generation glass is suitable for scenarios such as building facade photovoltaic curtain walls with high transmittance requirements. In the preparation process of thin-film solar cell modules, after the cadmium telluride power generation chip layer is deposited on the TCO layer glass by the near-space sublimation method, the split chip is etched into small cells by laser. The process also insulates the outer edge of the film layer, removes the outer edge film layer of the TCO glass, and retains a certain safety margin for bonding the front and rear back panels and preventing leakage. If the film layer remains, it will lead to unstable bonding, causing the front and rear glass plates to separate, and creating the risk of accelerated aging of the chip due to exposure to air, leakage and short circuit, etc.

[0003] In the prior art, the degree of cleaning of the cleared areas on the four sides of the film layer is generally judged by manual visual inspection, but the human error is large, or relevant detection equipment (such as a conductive pen or a megohmmeter) is used to detect the degree of cleaning of the cleared areas on the four sides of the film layer at a certain interval, but it can only check whether the insulation standard is met, and it is difficult to accurately detect the cleaning status of the cleared areas. Therefore, it is difficult to judge how to rework the film layer according to the cleaning status of the cleared areas. The detection accuracy is low, resulting in low battery assembly processing efficiency. Summary of the invention

Therefore, here we first identify whether the four-side clearance area has a size deviation based on the detection image, that is, whether there is a first type of defect. If so, the target part is directly marked as a scrap product. If not, it means that the cutting size of the four-side clearance area meets the standard, but there may still be a situation where impurities in the four-side clearance area are not removed properly. Therefore, here we continue to detect whether there are second-type defects. The second-type defects can characterize whether there are residues in the four-side clearance area. If so, the target part is marked as a repaired product, which is convenient for subsequent staff to perform secondary impurity removal based on the marking information. If there is no second-type defect, the target part can be marked as a qualified product. To sum up, this application combines machine vision recognition technology to accurately detect the cleaning status of the four-side cleaning areas of the power generation glass film layer, and mark the qualified status of the product.

[0061] Example 1

[0062] Reference Figure 1-Figure 5 This embodiment provides a method for detecting a light-transmitting power generation glass film layer, comprising the following steps:

[0063] Acquire a detection image of the target part based on a set viewing angle; wherein the target part is a power generation glass film layer to be detected, and the set viewing angle is a viewing angle having a four-side clearing area 110 facing the power generation glass film layer;

[0064] According to the detection image, it is identified whether the target part has a first type of defect; wherein the first type of defect is that the four-side clearance area 110 has a size deviation;

[0065] If there are first-class defects, the target part is marked as scrap;

[0066] If there is no first-type defect, then according to the detection image, it is identified whether the target part has a second-type defect; wherein the second-type defect is that the four-side clearing area 110 has residues;

[0067] If there are second-class defects, the target part is marked as a return product;

[0068] If there are no second-class defects, the target part is marked as a qualified product.

[0069] In this embodiment, machine vision recognition technology is used to collect a detection image of the target part at a set viewing angle (equivalent to a top-down viewing angle of the target part). The detection image can reflect the shape characteristics of the four-side clearance area 110 in the power generation glass film layer. Due to the cutting error, the outer edge chip layer in the power generation glass film layer may be cut off too much, resulting in the four-side clearance area 110 having a size deviation that cannot be corrected and needs to be scrapped. Therefore, here, it is first identified based on the detection image whether the four-side clearance area 110 has a size deviation, that is, whether there is a first type of defect. If so, the target part is directly marked as a scrapped product. If not, it means that the cutting size of the four-side clearance area 110 meets the standard, but there may still be a situation where impurities in the four-side clearance area 110 are not removed in place. Therefore, it is continued to detect whether there is a second type of defect. The second type of defect can indicate whether there is residue in the four-side clearance area 110. If so, the target part is marked as a repaired product, which is convenient for subsequent staff to perform secondary impurity removal according to the marking information. If there is no second type of defect, the target part can be marked as a qualified product. In summary, this embodiment combines machine vision recognition technology to accurately detect the cleaning status of the four-side cleaning area 110 of the power generation glass film layer and mark the qualified status of the product. It is highly intuitive, so that the staff can perform the next step according to the marked information, thereby improving work efficiency.

[0070] As an optional implementation, identifying whether the target part has the first type of defect according to the detection image includes:

[0071] According to the detection image, the contour information of the four-side clearing area 110 is identified; wherein the contour information includes an outer contour 120 and an inner contour 130 located within the outer contour 120, the outer contour 120 has four first cusps 140, and the inner contour 130 has four second cusps 150;

[0072] According to the contour information, the distances between the four first cusps 140 and the adjacent second cusps 150 are respectively obtained to obtain four distance measurement values;

[0073] It is determined whether the four spacing measurement values ​​are all equal to the preset spacing threshold value. If not, it is identified that the target part has the first type of defect.

[0074] In this embodiment, the contour information of the four-side clearance area 110 can be identified and extracted according to the detection image. For the power generation glass film layer with qualified cutting size deviation, the contour information of the four-side clearance area 110 should form a rectangular outer contour 120 and an inner contour 130. When there is a size deviation, the size of the inner contour 130 changes and may form an irregular quadrilateral, while the outer contour 120 is always a regular rectangle. Therefore, here, by calculating the distance between the four first cusps 140 of the inner contour 130 and the second cusps 150 adjacent to the outer contour 120, four spacing measurement values ​​(such as d1, d2, d3, and d4 in the figure) are obtained. If a size deviation occurs, at least one second cusp 150 is not located at the theoretical position, which causes at least one spacing measurement value to be unequal to the preset spacing threshold. Therefore, the size deviation can be characterized by calculating the spacing measurement value between the first cusp 140 and the adjacent second cusp 150, and the detection is accurate and effective.

[0075] As an optional implementation manner, if it is determined that the four distance measurement values ​​are all equal to the preset distance threshold, the method further includes:

[0076] Connect four first cusps 140 with adjacent second cusps 150 to obtain four reference lines 160;

[0077] Obtaining the angles α between the reference line 160 and the adjacent edge lines respectively; wherein the edge lines are the contour lines corresponding to the outer contour 120;

[0078] It is determined whether the angle α is equal to 45°. If so, it is determined that the target part does not have the first type of defect. If not, it is determined that the target part has the first type of defect.

[0079] In this embodiment, when it is determined that the four spacing measurement values ​​are all equal to the preset spacing threshold, it is possible that the second cusp 150 is offset and the offset position just falls on the arc formed by the first cusp 140 as the center and the spacing threshold as the radius (such as Figure 3 Therefore, in order to further improve the detection accuracy, four reference lines 160 are constructed here, and the angle α between the reference line 160 and the adjacent edge line is obtained. Only when the angle α is equal to 45°, it means that the second cusp 150 is not offset along the arc. Then, it can be accurately detected whether the second cusp 150 is in the theoretical position, thereby improving the detection accuracy of the first type of defects.

[0080] As an optional implementation, identifying whether the target part has the second type of defect according to the detection image includes:

[0081] According to the contour information, it is identified whether there is an abnormal pattern 170 in the four-side clearing area 110; wherein the abnormal pattern 170 is a pattern formed by blocky residues that have not been cleared in the four-side clearing area 110;

[0082] If the abnormal pattern 170 exists, it is identified that the target part has a second type of defect.

[0083] In this embodiment, when identifying the second type of defects, it is sufficient to identify whether there is an abnormal pattern 170 formed by partially uncleaned block residues in the four-side cleaning area 110. If so, it can be identified that the target part has the second type of defects and is marked as a reworked product to facilitate subsequent secondary cleaning processing.

[0084] As an optional implementation, if it is identified that there is no abnormal pattern 170 in the four-side clearing area 110, the method further includes:

[0085] According to the contour information, it is identified whether there is an abnormal shadow point 180 in the four-side clearing area 110; wherein the abnormal shadow point 180 is a shadow point formed by the point-shaped residues that are not cleared in the four-side clearing area 110;

[0086] Get the number of abnormal shadow points 180;

[0087] It is determined whether the number of abnormal shadow points 180 is greater than or equal to a preset number threshold. If so, it is identified that the target part has a second type of defect.

[0088] In this embodiment, when it is identified that there is no abnormal pattern 170 in the four-side clearing area 110, that is, there is no block-like residue, but there may also be some point-like residues left by incomplete cleaning. Too many point-like residues will also cause the subsequent four-side clearing area 110 to be unstable when bonded to the back panel. Therefore, the number of abnormal shadow points 180 formed by the point-like residues is also detected here. If the number is greater than or equal to the preset number threshold, repair and cleaning are required.

[0089] As an optional implementation, if it is determined that the number of abnormal shadow points 180 is less than a preset number threshold;

[0090] Identify whether there is a shadow point dense area 190; wherein the shadow point dense area 190 is an area surrounded by a plurality of dense abnormal shadow points 180;

[0091] If not, the identification target part does not have the second type of defect;

[0092] If it exists, the detection area of ​​the shadow point dense area 190 is obtained;

[0093] It is determined whether the detection area is greater than a preset area threshold. If not, it is determined that the target part does not have the second type of defect. If so, it is determined that the target part has the second type of defect.

[0094] In this embodiment, when the number of abnormal shadow points 180 detected is less than the preset number threshold, there may be a situation where some abnormal shadow points 180 are relatively concentrated, which may also easily lead to unreliable subsequent bonding. Therefore, here, the shadow point dense area 190 is identified and the detection area of ​​the shadow point dense area 190 is calculated. If the detection area is greater than the preset area threshold, it is necessary to repair and clean it. Otherwise, it can be directly marked as a qualified product, which improves the comprehensiveness of the detection of the second type of defects and improves the detection accuracy.

[0095] It should be noted that when identifying the shadow point dense area 190, the distance between adjacent abnormal shadow points 180 can be calculated. When there are multiple abnormal shadow points 180 with a distance less than a preset threshold, the multiple abnormal shadow points 180 can be marked, and finally the marked abnormal shadow points 180 are curve fitted to obtain the shadow point dense area 190.

[0096] As an optional implementation, acquiring a detection image of a target part based on a set viewing angle includes:

[0097] Acquire an original image of the target part based on a set viewing angle;

[0098] Perform grayscale processing on the original image to obtain a grayscale image;

[0099] Perform noise reduction on grayscale images;

[0100] The denoised grayscale image is binarized to obtain a black and white detection image.

[0101] In this embodiment, the original image of the target part is first acquired, and then grayscale processing, noise reduction processing and binarization processing are performed respectively, so that a detection image with clear contours and distinct black and white can be obtained, which is convenient for subsequent feature extraction and recognition.
