DETAILED DESCRIPTION

[0016] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0017] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0018] The first object of the present invention is to provide a photovoltaic glass integrity detection device, such as Figure 1 As shown, it includes a transmission roller table 3 and a detection device 4; the detection device 4 is arranged on the transmission roller table 3; the transmission roller table 3 is provided with a transmission entrance position detection device 1, a transmission exit position detection device 7 and a regularization device 2; the detection device 4 includes a camera 5 and a detection software system 8. The transmission entrance position detection device 1, the regularization device 2, the camera 5 and the transmission exit position detection device 7 are all connected to the detection software system 8.

[0019] Preferably, the detection device 7 also includes a supplementary light source 6; the supplementary light source 6 is connected to the camera 5; the supplementary light source 6 can provide stable and uniform lighting conditions for the camera 5, further improving the clarity and accuracy of the detection image; ensuring that high-quality detection images can be obtained under different lighting conditions, thereby improving the adaptability and reliability of the equipment.

[0020] The upper surface of the transmission roller table 3 is evenly distributed with anti-skid and wear-resistant rollers. The transmission roller table 3 is the basic platform of the entire detection equipment and is responsible for transporting the photovoltaic glass from one end to the other end. The upper surface of the transmission roller table 3 is evenly distributed with anti-skid and wear-resistant rollers, which not only ensures the stability of the glass during the transmission process, but also reduces scratches or damage caused by friction, thereby protecting the glass surface, improving the smoothness and safety of glass transmission, and reducing the risk of glass breakage due to improper transmission.

[0021] The transmission entrance position detection device 1 is a high-precision photoelectric sensor or uses laser ranging technology, which can accurately detect the position of the photovoltaic glass when it enters the transmission roller table 3. After the transmission entrance position detection device 1 detects the incoming photovoltaic glass, it transmits the signal to the detection software system 8, ensuring that the glass is in the correct position before entering the detection area, providing accurate basic data for subsequent detection work and improving detection accuracy.

[0022] The aligning device 2 includes adjustable side plates and pressure rollers, which are used to adjust the position and posture of the photovoltaic glass before detection, ensuring that the glass remains flat and perpendicular to the line of sight of the camera 5 during the detection process. By adjusting the position and posture of the glass, the detection error caused by glass tilt or offset is eliminated, thereby improving the accuracy and reliability of the detection; or the aligning device 2 includes a cylinder and an electromagnetic switch connected thereto; the electromagnetic switch is used to control the movement of the cylinder to adjust the position of the glass.

[0023] The camera 5 is a high-precision industrial camera. It uses a high-precision industrial camera with high resolution and fast imaging capabilities, and can capture subtle defects or cracks on the surface of photovoltaic glass; it ensures the clarity and details of the detection image, so that the detection software can more accurately identify and analyze the integrity of the glass surface.

[0024] The transmission exit position detection device 7 is connected to the alarm device. When it is detected that defective glass is about to leave the transmission roller table 3, the alarm device will be triggered to sound an alarm to alert the operator. The alarm device can promptly detect and mark defective glass to prevent it from flowing into the next process or the market. It can automatically screen out defective edges and corners of photovoltaic glass produced in the edge grinding process and output a defective alarm to the outside, thereby ensuring product quality.

[0025] The detection software system 8 is connected to the factory information system, which includes a manufacturing execution system and an enterprise resource planning system; by connecting the detection software system 8 to the factory information system, real-time transmission and sharing of detection data are achieved, which not only avoids the data island phenomenon, but also enables each link in the production process to make decisions and optimize based on unified and accurate data, thereby improving overall production efficiency and response speed. The detection software system 8 is the core of photovoltaic glass integrity detection, and its detection results directly reflect the product quality status; its integration with the factory information system enables these detection results to be quickly fed back to the production line, helping enterprises to discover and deal with quality problems in a timely manner, thereby improving the overall quality control level of the product.

[0026] The factory information system includes the manufacturing execution system (MES) and the enterprise resource planning system (ERP), which can receive and analyze the photovoltaic glass integrity data provided by the detection software system in real time; these data provide strong support for key links such as production scheduling, inventory management, and quality control, enabling enterprises to make decisions more quickly and accurately, reducing the risk of decision-making errors caused by information asymmetry or lag.

[0027] The second object of the present invention is to provide a method for using a photovoltaic glass integrity detection device, which specifically comprises the following steps: After the transmission entrance position detection device 1 on the transmission roller table 3 detects the incoming photovoltaic glass, it transmits the signal to the detection software system 8. The detection software system 8 controls the regularization device 2 to regularize the position of the passing photovoltaic glass. When the regularized photovoltaic glass is transported to the detection device 4, the camera 5 starts to work and transmits the glass image signal to the detection software system 8 in real time. The detection software system 8 converts the image signal into a digital signal and compares it with the various incomplete defects in the system. The excess is judged as a defective product. When the photovoltaic glass is transmitted to the transmission exit position detection device 7, a defective product signal and an alarm are output, and the production line processes the defective product.

[0028] Among them, when the overall light of the detection device 4 is dim, the supplementary light source 6 is turned on to provide stable and uniform lighting conditions for the camera 5; the data information obtained by the detection software system 8 is transmitted to the manufacturing execution system and the enterprise resource planning system for transmission and sharing of the detection data, and the manufacturing execution system and the enterprise resource planning system analyze the data and make adaptive adjustments to production scheduling, inventory management, quality control and other links.

[0029] The present invention has a simple structure and low cost, and can be used to detect the integrity of photovoltaic glass products such as edge chipping, corner chipping, under-grinding, cracks, and breakage caused by the edging process during production, thereby reducing factors such as equipment shutdown and failure caused by the bursting of defective product glass during subsequent processing.
