[0002] With the rapid development of the photovoltaic industry, photovoltaic frames, as a key component of photovoltaic modules, have seen increasing demand in the market. Polyurethane pultruded composites, with their lightweight, high-strength, corrosion-resistant, and excellent insulation properties, are gradually gaining prominence in the photovoltaic frame market. Compared to traditional aluminum alloy frames, polyurethane composite frames have lower density and weight, reducing transportation and installation costs while improving wind resistance and seismic performance. In addition, the manufacturing process of polyurethane composite frames is more environmentally friendly, helping to reduce carbon emissions and achieve green production. Therefore, polyurethane composite frames perform well in various applications, especially in harsh environments such as the ocean and desert. Their high corrosion resistance and high yield strength make them a significant advantage in coastal module designs that require higher back pressure. In addition, the multi-color selection and excellent insulation performance of composite frames also make them more advantageous in B IPV construction. However, the coating materials and technology of photovoltaic polyurethane composite frames directly affect the appearance, weather resistance, and environmental quality of photovoltaic frames. Unstable coating quality can cause problems such as fading, blistering, and peeling during use, affecting the overall performance and lifespan of photovoltaic modules. High-quality coating materials and advanced coating processes are needed to ensure the stability and weather resistance of the coating. The coating process is closely related to the conveying line, and the design and selection of the conveying line directly affect the efficiency and effectiveness of the coating process. The design of the conveying line needs to be closely linked to the coating process flow to ensure smooth transitions between processes, reduce workpiece transfer time, and improve production efficiency. Furthermore, with the development of the engineering machinery industry, coating engineering design concepts are constantly innovating, and higher requirements are placed on the conveying of coating lines. The conveying method of the coating line needs to be continuously optimized and improved to meet higher production demands and process requirements.
