Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic frame production, in particular to a photovoltaic frame pultrusion preformed yarn guide device. Background Art

[0002] With the continuous development of social economy, environmental pollution is becoming more and more serious, and people's thirst for clean energy is also increasing. Solar energy, as a widely existing clean energy, is becoming more and more important. In the development and utilization of solar energy, solar photovoltaic modules are important components that convert solar energy into electrical energy. The materials used in solar photovoltaic modules are exposed to sunlight for a long time during use, so they need to have good weather resistance and UV resistance to improve the durability and reliability of the equipment.

[0003] At present, most of the frames of solar photovoltaic modules (photovoltaic frames) are made of aluminum alloy materials, which are light in weight, strong in strength and firmness, and corrosion-resistant, so they are widely used. However, a high voltage will be formed between the circuit of the solar photovoltaic module and the grounded metal frame. After a period of operation outdoors, the output power of the solar photovoltaic module will decrease, resulting in reduced power generation efficiency and power station operation efficiency, further causing the continuous attenuation of the performance of the solar photovoltaic module, that is, the PID effect; once the PID effect occurs, it will greatly affect the operation of the power station and the investment income.

[0004] Composite materials are cheaper than aluminum alloy materials, and the production capacity of composite materials using polyurethane pultrusion process is more stable. High glass fiber content and high resistance make it possible to avoid grounding, further reducing costs. With the development of pultrusion technology, pultruded fiberglass products have developed from small size, simple shape, symmetrical and uniform to large, complex, asymmetrical pultruded products. For products with particularly complex structures, many corners and irregular shapes, especially those made of yarn and fiber felt cloth, wrinkles, looseness, deviation and other defects will occur after molding.
