Description

Technical Field

[0001] The utility model mainly relates to the technical field of coating devices, in particular to a portable photovoltaic module coating device. Background Art

[0002] The design service life of photovoltaic modules is usually 25 years. Due to the long-term exposure to wind, sun and rain during outdoor use, the performance of the module materials degrades, resulting in reduced photoelectric conversion efficiency. Under the influence of long-term dust accumulation, the power output of photovoltaic modules will drop significantly, and the attenuation of photovoltaic modules will be accelerated. The economic losses caused by dust in the world exceed US$5 billion each year. In order to solve the above problems, anti-fouling coating products applied to photovoltaic modules have appeared on the market. By performing a secondary coating on the outer glass surface of photovoltaic module products in photovoltaic power stations, the self-cleaning and dust-resistant functions of photovoltaic glass are enhanced, which can significantly improve the power generation efficiency, reduce the damage to the glass surface of photovoltaic module products, and reduce economic losses.

[0003] Since photovoltaic power stations are generally built in outdoor scenes such as plains, roofs, and mountains, and the coating cycle of the secondary coating is relatively short, generally ranging from 1 to 5 years per time, photovoltaic power stations need to be repeatedly coated on a periodic basis to replenish the eroded coating layer. It cannot be produced directly by glass manufacturers like coated glass, and must be coated on-site at the photovoltaic power station system according to the coating cycle. At present, the conventional coating method is to use a sponge brush or a dust-free cloth for application. This coating method is relatively crude. On the one hand, due to manual operation, uneven force is prone to occur, resulting in different coating layer thicknesses, and the coating layer thickness cannot be controlled. On the other hand, the coating layer curing problem cannot be solved, the temperature and humidity of the coating layer cannot be controlled, and there is a lot of dust mixed in the outdoor air, which is easy to be integrated into the coating liquid to reduce the performance of the coating layer.

[0004] Some practitioners have designed portable coating devices. For example, Chinese patent application CN202021932569.9 discloses a portable coating device. Although this patent solution can automatically clean the surface of the coated object during the coating process, it still cannot solidify the coating liquid in time. During outdoor use, it cannot prevent impurities in the air from entering the coating liquid, affecting the performance of the coating layer. Chinese patent application CN201621433808.X discloses a portable coating machine for coating the surface of photovoltaic module glass. In this solution, the photovoltaic module glass is coated by applying a coating cloth, and the coating cloth is pressed by a hose to ensure that the contact force with the glass surface is consistent. However, since the thickness of the coating layer is usually at the micron level or even nanometer level, the surface of the coating cloth itself is uneven, and the error may be higher than the thickness of the coating layer, and the thickness of the coating cannot be guaranteed to be consistent.

[0028] In this embodiment, an exhaust component 3 is further provided in the spraying and coating curing mechanism 1, and the exhaust component 3 is used to continuously exhaust gas during the coating process.
