[0059] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0060] Figure 1 is a schematic diagram of a photovoltaic module tape application system according to an exemplary embodiment. Figure 1 As shown, the photovoltaic module tape system includes:

[0061] Central control subsystem 1, tape application subsystem 2 and intelligent identification subsystem 3.

[0062] The central control subsystem 1 is connected to the adhesive tape applying subsystem 2 and the intelligent identification subsystem respectively.

[0063] The intelligent identification subsystem 3 is used to obtain the real-time three-dimensional model corresponding to the photovoltaic component being transmitted to the adhesive tape subsystem 2 within a first preset time period, and send the real-time three-dimensional model to the central control subsystem 1;

[0064] The central control subsystem 1 is used to obtain the tape information according to the three-dimensional model within a second preset time period, and send the tape information to each tape subsystem 2; the tape information includes the tape position, the tape path and the tape duration, and the sum of the first preset duration and the second preset duration is less than the time required for the photovoltaic module to be transmitted to the tape subsystem 2;

[0065] The tape attaching subsystem 2 is used to execute the tape attaching task of the photovoltaic module according to the tape attaching information.

[0066] In the present disclosure, before the taping subsystem 2 performs taping, while the photovoltaic component is transmitting to the taping subsystem 2, the intelligent identification subsystem 3 will obtain the real-time three-dimensional model corresponding to the photovoltaic component within a preset time period, and then send the real-time three-dimensional model to the central control subsystem 1. After receiving the real-time three-dimensional model, the central control subsystem 1 obtains the taping information corresponding to the transmitted photovoltaic component, and then sends the taping information to the taping subsystem 2 that completes the taping task. After receiving the taping information, the taping subsystem 2 can perform the taping task.

[0067] Since the sum of the first preset time and the second preset time is less than the time required for the photovoltaic component to be transmitted to the tape subsystem 2, the tape subsystem 2 will not mistakenly affix the first photovoltaic component or the first few photovoltaic components, thereby improving the tape laminating quality.

[0068] In the present disclosure, through the cooperation of the intelligent identification subsystem 3 and the central control subsystem 1, the tape information corresponding to the photovoltaic module can be quickly determined, thereby improving the tape efficiency and saving production costs.

[0069] Furthermore, the intelligent identification subsystem 3 can continuously obtain the real-time three-dimensional model corresponding to the photovoltaic component being transmitted to the tape subsystem 2 according to a preset time period. When it is detected that the real-time three-dimensional model collected in the current time period is different from the real-time three-dimensional model collected in the adjacent previous time period, the real-time three-dimensional model collected in the current time period is sent to the central control subsystem 1, so that the central control subsystem 1 re-determines the tape parameters based on the new real-time three-dimensional model. In this way, the purpose of quickly determining the tape information of photovoltaic components of different models can be achieved, thereby realizing the rapid switching and automatic adaptation of photovoltaic components of different models and improving the flexibility of the production line.

[0070] In the present disclosure, a plurality of adhesive tape subsystems 2 may be included, and each adhesive tape subsystem 2 may include: a feeding mechanism, a cutting mechanism, an attaching mechanism, and a position adjusting mechanism.

[0071] In order to improve the accuracy of tape application and improve the quality and yield of products, the feeding mechanism can use a feeding wheel driven by a high-precision servo motor, equipped with encoder feedback, to achieve precise tape delivery control. The cutting mechanism can use a rotary cutter driven by a high-speed servo motor, combined with a precision photoelectric sensor to ensure a cutting accuracy of ±0.1mm. The attachment mechanism can use a pneumatic-electric hybrid control roller system, with pressure continuously adjustable in the range of 0-100N, to ensure that tapes of different thicknesses and materials can be smoothly attached. The position adjustment mechanism can be driven by a linear motor to achieve XYZ three-axis fine-tuning with an adjustment accuracy of 0.01mm.

[0072] In one embodiment, Figure 2 As shown, in terms of obtaining the real-time three-dimensional model corresponding to the photovoltaic assembly being transmitted to the adhesive tape subsystem 2, the intelligent identification subsystem 3 is specifically used for the following steps A1-A4:

[0073] A1. Acquire an image of the photovoltaic module being transmitted to the tape application subsystem 2.

[0074] A2. Acquire characteristic parameters of the photovoltaic module according to the image of the photovoltaic module.

[0075] A3. Acquire an initial three-dimensional model of the photovoltaic module from a database according to characteristic parameters of the photovoltaic module; and save a mapping relationship between the characteristic parameters and the initial three-dimensional model in the database.

[0076] A4. The initial three-dimensional model is adjusted according to the difference parameters between the characteristic parameters of the photovoltaic module and the characteristic parameters corresponding to the initial three-dimensional model to obtain a real-time three-dimensional model.

[0077] The intelligent recognition subsystem 3 in the present disclosure may include: an image acquisition subsystem, an image processing unit, a 3D reconstruction module and a database.

[0078] Among them, the image acquisition subsystem can include at least two high-resolution (≥20 million pixels) industrial cameras, using an adjustable LED structured light source. The image processing unit uses a high-performance GPU-accelerated deep learning processor, running an improved YOLOv5 algorithm to achieve a recognition speed of <50ms. The 3D reconstruction module can achieve accurate 3D reconstruction of the component surface based on the principle of binocular vision and combined with structured light technology, with an accuracy of 0.1mm. The database can adopt a distributed database architecture to store the characteristic parameters of various types of photovoltaic modules and the initial 3D models of various types of photovoltaic modules.

[0079] Specifically, after the intelligent recognition subsystem 3 is started, the image acquisition subsystem obtains the image of the photovoltaic module being transmitted to the adhesive tape subsystem 2. The image processing unit obtains the characteristic parameters of the photovoltaic module from the image of the photovoltaic module according to the improved YOLOv5 algorithm. The 3D reconstruction module obtains the initial three-dimensional model of the photovoltaic module from the database according to the characteristic parameters of the photovoltaic module, and the 3D reconstruction module adjusts the initial three-dimensional model according to the difference parameters in the characteristic parameters of the photovoltaic module and the characteristic parameters corresponding to the initial three-dimensional model to obtain a real-time three-dimensional model.

[0080] Due to the actual deformation of the components and the diverse component designs, the 3D model of the actual photovoltaic component will be different from the initial three-dimensional model. In order to adapt to the differences in photovoltaic components, it is necessary to reconstruct the three-dimensional model and adjust the initial three-dimensional model.

[0081] The actual deformation of the photovoltaic module may include, among others, material properties and surface unevenness.

[0082] Material properties refer to the deformation of photovoltaic modules during production or transportation due to factors such as temperature and humidity. The reconstruction of the 3D model can take these deformations into account to ensure the accuracy of the adhesive bonding position and path. Surface unevenness refers to the fact that the surface of the module may not be perfect. The reconstruction of the 3D model can better reflect the actual surface conditions and avoid poor tape bonding due to surface unevenness.

[0083] Among other things, the diverse module designs of photovoltaic modules include model variants and additional features.

[0084] Model variants refer to the fact that even the same model of PV modules may have slight differences due to batches, production processes, etc. The reconstruction of the 3D model can help adjust for these specific differences. Additional features refer to the fact that different PV modules may have different accessories or design features (such as the location of the junction box), which need to be reflected in the 3D model to ensure the accuracy of the tape attachment.

[0085] In one embodiment, Figure 3 As shown, in terms of obtaining the tape application information according to the real-time three-dimensional model, the central control subsystem 1 is specifically used to perform the following steps B1-B3:

[0086] B1. Obtain initial tape information based on the real-time 3D model.

[0087] B2. Obtain current environmental information, which includes current temperature information and current humidity information.

[0088] B3. Adjust the initial tape application information according to the current environment information to obtain the tape application information.

[0089] Since environmental information will affect the tape information, in the present disclosure, after obtaining the initial tape information based on the real-time three-dimensional model, it is also necessary to obtain the current environmental information and adjust the initial tape information based on the current environmental information to obtain the tape information that conforms to the current environmental information, thereby improving the tape fitting quality.

[0090] Figure 4 is a schematic diagram of a photovoltaic module tape application system according to an exemplary embodiment. Figure 4 As shown, the photovoltaic module tape sticking system also includes: a tension control subsystem 4.

[0091] The tension control subsystem 4 is connected to the control subsystem and the adhesive tape applying subsystem 2 respectively.

[0092] The tension control subsystem 4 is used to obtain the real-time tape tension when the tape applying subsystem 2 is working, and when it is detected that the real-time tape tension does not meet the target tension value requirement, send a tape tension adjustment instruction to the central control subsystem 1;

[0093] The control subsystem is used to send the received tension adjustment instruction to the adhesive tape applying subsystem 2;

[0094] The adhesive tape applying subsystem 2 is used to adjust the tension of the adhesive tape according to the tension adjustment instruction.

[0095] The tension control subsystem 4 in the present disclosure may include: a high-precision tension sensor; and a tension adjustment mechanism may also be provided in the adhesive tape applying subsystem 2.

[0096] The high-precision tension sensor can measure 0-50N with an accuracy of 0.1% FS. The tension adjustment mechanism includes an active tension wheel driven by a servo motor and a passive tension wheel controlled by pneumatics.

[0097] The tension control subsystem 4 samples the real-time tape tension at a frequency of 1 kHz. When it is detected that the real-time tape tension does not meet the target tension value requirement, it obtains the tension parameter to be adjusted, and then carries the tension parameter to be adjusted in the tape tension adjustment instruction and sends it to the central control subsystem 1. The central control subsystem 1 forwards the received tension adjustment instruction to the tape applying subsystem 2. The tape applying subsystem 2 adjusts the position and damping of the active tension wheel according to the tension parameter to be adjusted, and / or adjusts the position and damping of the passive tension wheel, so that the adjusted tape tension meets the target tension value requirement.

[0098] During regulation, a suitable control algorithm can be selected, such as PID control, fuzzy control or adaptive control.

[0099] For example, when using PID control, proportion (P), integration (I) and differentiation (D) are used to calculate the control signal to adjust the position and damping of the active tension wheel and / or adjust the position and damping of the passive tension wheel.

[0100] In one possible implementation, the tension control subsystem 4 can determine the tension fluctuation corresponding to the real-time tape tension based on the relationship between the real-time tape tension and the target tension value.

[0101] When it is detected that the tension fluctuation is a small fluctuation, the adhesive tape applying subsystem 2 is controlled to adjust the position and damping of the active tension wheel according to the PID control, and / or adjust the position and damping of the passive tension wheel;

[0102] When it is detected that the tension fluctuation is a periodic fluctuation, the adhesive tape applying subsystem 2 is controlled to adjust the speed curve of the feeding wheel;

[0103] When it is detected that the tension fluctuation is a sudden and large fluctuation, the central control system triggers an alarm and waits for human intervention.

[0104] Among them, small fluctuations usually refer to tension changes with relatively small amplitudes within the allowable tolerance range. These fluctuations will not significantly affect product quality or production efficiency and can usually be quickly compensated by automatic control systems (such as PID control). For example, the amplitude of small fluctuations is usually within a pre-set threshold range, such as ±1% to ±5% of the target tension value.

[0105] Figure 5 is a schematic diagram of a photovoltaic module tape application system according to an exemplary embodiment. Figure 5 As shown, the photovoltaic module tape application system also includes: a real-time quality monitoring subsystem;

[0106] The real-time quality monitoring subsystem is connected to the central control subsystem 1;

[0107] The real-time instruction monitoring subsystem is used to detect the tape feedback information of the tape applied to the photovoltaic module during the process of the tape application subsystem 2 applying the tape, and send the tape feedback information to the central control subsystem 1; the tape feedback information includes: defects on the surface of the tape, bubbles between the tape and the photovoltaic module, the straightness and flatness of the edge of the tape, and the temperature distribution of the tape during application;

[0108] The central control subsystem 1 is used to receive tape feedback information; compare the tape feedback information with the preset tape standard information to obtain the quality level; obtain the corresponding processing strategy from the preset problem processing table according to the quality level, and execute the processing strategy; the problem processing table includes the mapping relationship between the quality level of each tape and the corresponding processing strategy.

[0109] The real-time quality monitoring subsystem works continuously during the glue laminating process. In the present disclosure, the real-time quality monitoring subsystem includes: a multi-spectral camera, a line laser sensor, a thermal imaging camera and an edge computing unit.

[0110] The edge computing unit includes: high-performance embedded processors, real-time data processing algorithms, and lightweight machine learning models. Among them, high-performance embedded processors, such as NVIDIA Jetson Xavier NX; real-time data processing algorithms include signal filtering, feature extraction, fast Fourier transform, etc.; lightweight machine learning models are used for abnormal information detection and predictive maintenance.

[0111] Among them, the multispectral camera, line laser sensor, and thermal imaging camera are all connected to the edge computing unit. The edge computing unit detects surface defects and bubbles on the tape based on the images taken by the multispectral camera, measures the straightness and flatness of the tape edge based on the data obtained by the line laser sensor, and analyzes the temperature distribution during the gluing process based on the images taken by the thermal imaging camera.

[0112] After receiving the tape feedback information, the central control subsystem 1 compares the tape feedback information with the preset tape standard information to obtain the quality level; obtains the corresponding processing strategy from the preset problem processing table according to the quality level, and executes the processing strategy; the problem processing table includes the mapping relationship between each quality level and the corresponding processing strategy.

[0113] The quality is continuously monitored during the glue lamination process, and the stable quality of each batch of photovoltaic modules is ensured through a real-time feedback mechanism.

[0114] In terms of executing the processing strategy, the central control subsystem 1 is specifically used for:

[0115] When the quality level is level 1, the tape feedback information and quality level are saved;

[0116] When the quality level is level 2, a target parameter affecting the quality level of the adhesive tape is obtained; an adjustment parameter of a target system corresponding to the target parameter is obtained, and the adjustment parameter is sent to the target subsystem so that the target subsystem is automatically corrected according to the adjustment parameter;

[0117] When the quality level is level three, an alarm message is output and the photovoltaic module tape system is controlled to shut down.

[0118] Among them, level one can be understood as a minor problem, level two can be understood as a moderate problem, and level three can be understood as a serious problem.

[0119] Minor issues are those that do not affect the function or safety of the product and have a minor impact on the appearance or minor performance parameters of the final product. For example, minor surface flaws, color inconsistencies, etc.

[0120] Medium problems may affect the performance of the product, but are still within the acceptable tolerance range. They have some impact on production efficiency or subsequent processes. For example, tension fluctuations exceed a certain range, but will not cause the product to be scrapped.

[0121] Serious issues directly affect the function, safety or compliance of the product. They may cause major safety hazards or large-scale defects. For example, structural damage, major dimensional errors or products that do not meet safety standards.

[0122] For the detected quality problems, the central control subsystem 1 can automatically classify and take corresponding measures by obtaining the corresponding processing strategy system according to the preset problem processing table:

[0123] Minor issues: record and mark, and allow production to continue;

[0124] Moderate problems: Try automatic corrections, such as adjusting pressure or reattaching;

[0125] Serious problem: shut down immediately, alarm and wait for manual processing.

[0126] In one embodiment, when applying the tape, the tape heater and the cutting knife in the tape applying subsystem 2 need to be preheated to ensure that they reach the best working state. Therefore, the central control subsystem 1 is also used to send a preheating instruction to the tape applying subsystem 2 after detecting that the photovoltaic module tape applying system is turned on; the tape applying subsystem 2 is used to perform the device preheating task according to the preheating instruction.

[0127] Furthermore, when the photovoltaic module tape sticking system is just powered on, the system needs to be initialized.

[0128] After power-on, the central control subsystem 1 executes a power-on self-test program to check whether the system status is normal. The system status includes: the connection status and working status of each subsystem; after detecting that the system status is normal, the central control subsystem 1 loads the database into the intelligent identification subsystem 3; the central control subsystem 1 can also control each actuator to perform origin regression and precision calibration; the central control subsystem 1 can also control the tape subsystem 2 to preheat key components, such as tape heaters, cutting knives, etc., to ensure that they reach the best working state.

[0129] In one embodiment, when there are multiple taping subsystems 2, in order to ensure the synchronization of work, the central control subsystem 1 is also used to send a synchronization start signal to the taping subsystem 2; in terms of executing the taping task of the photovoltaic module according to the taping information, the taping subsystem 2 is specifically used to: after receiving the synchronization start signal, execute the taping task of the photovoltaic module according to the taping information.

[0130] In one embodiment, the tape applying subsystem 2 is also used to send abnormal information to the central control subsystem 1 when abnormal information is detected; the abnormal information includes at least one of the following abnormal information: the tape is broken, the tape is wrinkled, and the tape applying subsystem 2 fails. The central control subsystem 1 is also used to execute an adjustment strategy corresponding to the abnormal information.

[0131] The tape applying subsystem 2 will also detect whether there is tape breakage, tape wrinkling, or equipment failure in the tape applying subsystem 2. The above abnormal information may also include: sudden changes in environmental conditions and displacement of component positions. When abnormal information failure is detected, the abnormal information will be sent to the central control subsystem 1 so that the central control subsystem 1 executes the adjustment strategy corresponding to the abnormal information. The adjustment strategy may include:

[0132] a. The central control subsystem 1 immediately suspends the operation of the relevant workstations.

[0133] b. The central control subsystem 1 quickly assesses the severity and impact scope of abnormal information.

[0134] c. The central control subsystem 1 attempts to automatically process:

[0135] 1) For tape problems, the central control subsystem 1 controls the start of a spare tape roll or attempts to re-feed;

[0136] 2) For position deviation, the central control subsystem 1 controls the use of the visual system to reposition and compensate;

[0137] 3) If the tape applying subsystem 2 fails, the central control subsystem 1 controls and attempts to reset or switch to the backup tape applying subsystem 2 .

[0138] d. If the automatic processing fails, the central control subsystem 1 will:

[0139] Send out an alarm signal, display detailed fault information and suggested treatment methods, and wait for human intervention.

[0140] e. After manual intervention, the central control subsystem 1 system performs self-checking and calibration procedures;

[0141] f. Resume normal production, and the central control subsystem 1 will specially mark the affected components.

[0142] The system disclosed in the present invention has the ability to automatically detect and process abnormal information, thereby improving the stability and reliability of the system.

[0143] The present disclosure may also include a cloud server, which is connected to the central control subsystem 1 .

[0144] The cloud server includes: distributed storage system, big data analysis platform, deep learning training platform and knowledge graph system. Among them, the distributed storage system is used to store and manage massive production data; the big data analysis platform is based on Hadoop and Spark architecture; the deep learning training platform is used to continuously optimize recognition algorithms and control strategies; the knowledge graph system builds a knowledge base of the production process to support intelligent decision-making.

[0145] The cloud server receives data from multiple production lines and performs the following processing: data aggregation and storage optimization, cross-production line and cross-time data correlation analysis, and the use of advanced machine learning algorithms to discover deep patterns.

[0146] The cloud server also performs the following advanced analysis tasks: analysis of factors affecting product quality, identification of equipment performance degradation patterns, location of production efficiency bottlenecks, and generation of energy consumption optimization solutions.

[0147] Based on the analysis results, the cloud server automatically generates optimization suggestions, including: process parameter adjustment plans, equipment maintenance plans, production scheduling optimization strategies, and raw material quality control suggestions.

[0148] The cloud server pushes the optimization suggestions to the central control subsystem 1.

[0149] In the above embodiments, the central control subsystem 1 is a high-performance industrial PC equipped with a multi-core CPU and a large-capacity memory, and a real-time operating system to ensure that the control cycle is <1ms. It also includes a human-machine interface and uses a large-size touch screen to provide an intuitive operating interface and real-time status display.
