[0041] In order to facilitate the understanding of the present application, the present application will be described in more detail below with reference to the relevant drawings. The drawings show embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.
[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device is inverted consistent with the orientation shown in the figure, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. The devices can also be oriented in the other direction (e.g., rotated 90 degrees or at other orientations) and the included spatially relative terms are intended to be interpreted accordingly.
[0044] It is noted that when an element is referred to as being "connected", it can be directly connected to the other element or connected via intervening elements. Also, "connected" in the following embodiments, if there is a transmission of electrical signals or data between the connected objects, should be understood as "electrically connected", "communicatively connected", etc.
[0045] As used herein, the singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise. It should also be understood that the term "comprising" or "having" etc. specifies the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, but does not preclude the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof.
[0046] As described in the background, in the conventional technology, when the film is offset, manual correction is generally used for adjustment, however, the manual detection of film offset is generally observed by the naked eye, and the film laying process is relatively fine, and in the case of a very small film offset angle, the naked eye may not be able to detect the film offset, and therefore, the conventional film detection method has the problem of low detection accuracy.
[0047] To solve the above problems and improve the detection accuracy, a photovoltaic module film detection system is provided to solve the problem of low accuracy of manual film offset detection.
[0048] Based on the above reasons, the present application provides a photovoltaic module film detection system, which Figure 1As shown, it comprises a label collection device 10, an image detection device 20 and an optical detection device 30 arranged in sequence; the image detection device 20 connects the label collection device 10 and the optical detection device 30; the label collection device 10 is used to collect the module label of the photovoltaic module covered with the film; the image detection device 20 is used to collect the module image of the photovoltaic module in the case of obtaining the module label; the optical detection device 30 is used to obtain the module label and the module image of the photovoltaic module, and in the case that the module image represents that the film covered by the photovoltaic module exists offset, the photovoltaic module is optically detected.
[0049] The label collection device 10 is a device for automatically recognizing and collecting label information on products, articles or equipment. These label information may include bar code, two-dimensional code, label, serial number, production date, expiration date, etc. In some specific embodiments, the label collection device 10 can include: a data collection component: responsible for capturing the label information on the target object, may contain imaging devices (such as cameras), light emitting devices and position sensors (such as photoelectric switches), used to ensure accurate capture and identification of labels. Data recognition component: process the images or signals obtained by the data collection unit, extract the required label information, and store or transmit it. Control component: coordinates the work of each part to ensure the smooth progress of the entire collection process. In addition, some label collection devices may also have wireless communication functions, which can transmit the collected data to the cloud or designated database in real time.
[0050] The image detection device 20 is a device or system that uses image processing technology to detect and recognize specific targets or features in images. It is widely used in many fields, such as video surveillance, autonomous driving, medical image analysis, industrial automation, etc. Specifically, the image detection device 20 can use image capture devices (such as cameras) to capture the images of target objects, pre-process the captured images, including denoising, contrast enhancement, edge detection, etc. to improve image quality and facilitate subsequent processing, then extract feature information such as shape, color, texture, etc. in the image through image processing algorithms, according to the extracted feature information, detect and recognize specific targets or features in the image, and finally output the detection results in the form of images, data or signals for subsequent processing or control.
[0051] The optical detection device 30 is a device for detecting the properties of an object using optical principles. The photovoltaic module, also known as a solar panel, is a device that converts sunlight into electrical energy using the photovoltaic effect. During the manufacturing process of the photovoltaic module, two layers of adhesive film need to be laid. The two layers of adhesive film are laid on the back of the module cell sheet. The adhesive film is used for bonding between the various layers of materials inside the module, has sealing and insulating effects, has long-term weather resistance, high and low temperature impact resistance, high light transmittance, and can improve the power generation efficiency. The module identification is a way of uniquely identifying the photovoltaic module. The module image is a module image of the photovoltaic module taken by a camera, which can reflect the processing of the photovoltaic module.
[0052] Specifically, during the manufacturing process of the photovoltaic module, two layers of adhesive film need to be laid. The two layers of adhesive film are laid on the back of the module cell sheet. The adhesive film is used for bonding between the various layers of materials inside the module, has sealing and insulating effects, has long-term weather resistance, high and low temperature impact resistance, high light transmittance, and can improve the power generation efficiency. If the adhesive film is offset and not handled in time, the adhesive film of the photovoltaic module is offset in the blank, and the AOI (Automatic Optical Inspection) detection function attached to the optical detection device 30 cannot identify the adhesive film offset in the blank. If the module is transferred to the laminating stage, it will cause problems such as lack of adhesive, bubble degradation loss, and overflow of the photovoltaic module at the four corners and the long edge. Therefore, the adhesive film of the photovoltaic module needs to be detected. After the second adhesive film is laid on the photovoltaic module, the module identification of the photovoltaic module covered with the adhesive film can be collected by the identification collection device 10 to determine the module information of the photovoltaic module. Then the image detection device 20 works. If the image detection device 20 obtains the module identification, the module image of the photovoltaic module can be collected to determine the actual processing of the photovoltaic module. Then the optical detection device 30 works to obtain the module identification and the module image of the photovoltaic module. If the module image represents that the adhesive film covered by the photovoltaic module is offset, the photovoltaic module needs to be optically detected to determine whether the photovoltaic module has other defects.
[0053] In some embodiments, the operation of determining whether the module image represents that the adhesive film covered by the photovoltaic module is offset can be determined by the image detection device 20 or the optical detection device 30. Specifically, if it is determined by the image detection device 20, after the image detection device 20 collects the module image of the photovoltaic module, the module image is determined. If the module image represents that the adhesive film covered by the photovoltaic module is offset, the module image and the module identification are sent to the optical detection device 30. If it is determined by the optical detection device 30, after the optical detection device 30 obtains the module identification and the module image of the photovoltaic module, the module image is determined. If the module image represents that the adhesive film covered by the photovoltaic module is offset, the photovoltaic module is optically detected.
[0054] The photovoltaic module film detection system is configured with an identification acquisition device for acquiring the component identification of the photovoltaic module covered with the film; the image detection device is configured to acquire the component image of the photovoltaic module under the condition that the component identification is acquired, so as to realize the association and binding between the component image and the component identification; the optical detection device is configured to acquire the component identification and the component image of the photovoltaic module, and to perform optical detection on the photovoltaic module under the condition that the film covered by the photovoltaic module is offset, so as to further detect the photovoltaic module under the condition that the film covered by the photovoltaic module is offset, and to obtain the film detection result of the photovoltaic module. The film detection of the photovoltaic module is performed by using the above system, on one hand, the detection condition is associated with the photovoltaic module by configuring the identification acquisition device, so as to provide data basis for subsequent abnormality troubleshooting and traceability; on the other hand, the optical detection device is configured to further perform optical detection on the photovoltaic module under the condition that the film is offset, so as to improve the detection efficiency while ensuring the accuracy of the photovoltaic module film detection.
[0055] In one embodiment, as shown in FIG. 1, the image detection device 20 includes a first communication module 21, an image acquisition module 22, and an offset judgment module 23; the first communication module 21 is connected with the identification acquisition device 10, the optical detection device 30, the image acquisition module 22, and the offset judgment module 23; the offset judgment module 23 is connected with the image acquisition module 22, and is used for judging the offset condition of the film covered by the photovoltaic module according to the component image acquired by the image acquisition module 22.

[0060] The shunting device 40 refers to a device that can shunt the photovoltaic component to different processes. The optical detection process is the process in which the optical detection device 30 is located. The laminating process is the next process after the secondary film is laid, which is a process of laminating the composite material laminated plate or other laminated materials that have been coated with the secondary film into an integrated whole through heating and pressing.
[0061] Specifically, if the deviation condition is deviation, it indicates that the film covering condition of the photovoltaic component is unqualified, therefore, the photovoltaic component needs to be shunted to the optical detection process by the shunting device 40 for the next optical detection to determine whether the photovoltaic component has other defects. If the deviation condition is no deviation, it indicates that the film covering condition of the photovoltaic component is qualified, therefore, the photovoltaic component can be shunted to the laminating process by the shunting device 40 for the next component processing.
[0062] In the embodiment, the shunting device 40 is added, which can shunt the photovoltaic component according to the deviation condition to ensure the normal progress of the photovoltaic component processing process.

[0066] In the embodiment, the first communication module 21 includes the signal receiving unit 211 and the signal sending unit 212, can complete the acquisition and sending of data, and ensures the normal progress of the communication process.

[0068] The pose adjustment module 24 is a module that can adjust the pose, and is mainly used for adjusting and controlling the position and attitude of the equipment or object.
[0069] Specifically, the image detection device 20 needs to take the glass long side edge and the glass short side edge as the reference to perform the photographic detection. If the image collection module 22 cannot take the above-mentioned edges as the reference due to the inclination or distortion of the photographed picture, the pose adjustment module 24 needs to adjust the pose of the image collection module 22, so as to ensure the accuracy of the image collection.
[0070] In one of the embodiments, as shown in the figure, Figure 6 The pose adjustment module 24 includes the control unit 241 and the pose adjustment unit 242; the control unit 241 and the pose adjustment unit 242 are both connected with the image collection module 22.
