[0002] Photovoltaic glass coating surface drying refers to the process of drying and curing the film after it is applied to the surface of the photovoltaic glass. This process is crucial to ensuring the quality and performance of the film, as it directly affects the photovoltaic cell's photoelectric conversion efficiency and long-term stability.

[0023] In the utility model, a thin film material is sprayed on the photovoltaic glass panel transmitted to the coating platform 1 through a spray tube 2, and then passes through a flat film roller 10, wherein the reduction motor 9 drives the flat film roller 10 to rotate at the same speed as the speed of the photovoltaic glass panel transmitting the glass. Then, the thin film material on the photovoltaic glass panel passes through the flat film roller 10, which can balance the uniformity of the thin film material to a certain extent. The fan 4 inside the bellows 3 is energized to work, and the external air is drawn into the inside of the bellows 3, and then introduced into the surface drying rod 5 and discharged through the air outlet 6. When discharged through the air outlet 6, it will pass through the first guide blade 7, and the first guide blade 7 is used to guide the passing air in an orderly manner, reducing the loss of airflow and the generation of vortexes. At the same time, the gaps between the blades of the first guide blade 7 disperse the air, which helps to evenly distribute the air, effectively avoid or reduce the corrugation of the thin film material on the photovoltaic glass panel caused by wind force, and improve the surface drying effect of the film.

[0024] Among them: a partition 11 is fixedly installed on the wind box 3, a second guide blade 12 is fixedly installed on the partition 11, the fan 4 and the second guide blade 12 are respectively located on both sides of the partition 11, and a heating wire 14 is fixedly installed inside the wind box 3, and the heating wire 14 is located between the partition 11 and the fan 4.

[0025] In the present invention, the air sucked in by the blower 4 is heated by the heating wire 14 and then mixed after passing through the second guide blade 12 to ensure the uniformity of the air heat, thereby improving the drying and solidification effect of the surface drying rod 5 on the film.

[0026] Wherein: a pattern cleaning roller 13 is rotatably mounted on the bracket 8 , and the bottom of the pattern cleaning roller 13 is in contact with the flat film roller 10 .

[0027] In the present invention, the thin film material adhered to the flat film roller 10 is cleaned by the cleaning roller 13 to ensure the flat film roller 10 has a smoothing effect on the thin film material on the photovoltaic glass panel.

[0030] The air outlet 6 is tilted downward, and the tilt direction is toward the flat film roller 10 .

[0031] In the present invention, it is ensured that the air outlet 6 can blow toward the film on the photovoltaic glass panel.
