Description

Technical Field

[0001] The utility model relates to the technical field of air drying, in particular to an air drying device for the surface of a photovoltaic solder ribbon. Background Art

[0002] In the processing technology of solar photovoltaic solder ribbons, it is necessary to clean the surface of the tinned photovoltaic solder ribbons. The photovoltaic solder ribbons are conveyed into a cleaning tank with a cleaning agent through a conveying device. The cleaning agent is used to clean the tin ash on the surface of the photovoltaic solder ribbons and generate a protective film on the surface of the photovoltaic solder ribbons to prevent the photovoltaic solder ribbons from oxidizing and blackening. In order to air dry the remaining moisture after cleaning the photovoltaic solder ribbons, an air drying device is generally arranged behind the cleaning tank. Since the photovoltaic solder ribbons will not only have residual moisture on their surfaces but also be easily mixed with a small amount of tin ash after cleaning, when air drying, the tin ash will be discharged outwards along with the air flow, causing environmental pollution to the processing site. It is found in the search that in the utility model patent with the Chinese patent publication number CN220269967U, an air drying device for the surface of a photovoltaic solder ribbon is disclosed. It can filter and intercept the tin ash contained in the discharged waste gas through a filtering mechanism, and discharge the filtered gas to the outside to avoid environmental pollution. However, when air drying, it uses a structure of directly blowing by an air drying box to air dry the photovoltaic solder ribbons, and the wind direction is perpendicular to the surface of the photovoltaic solder ribbons. Under the action of the wind, the moisture and tin ash are more likely to be pressed on the surface of the photovoltaic solder ribbons and are not easy to fall off. Moreover, it is easy to cause the photovoltaic solder ribbons to be deformed under the pressure of the wind for a long time. In addition, not only the upper surface of the photovoltaic solder ribbons has moisture, but also the lower surface has moisture. Therefore, the existing technology still has a poor air drying effect on the photovoltaic solder ribbons and needs to be improved. Summary of the Utility Model
