Description

Technical Field

[0001] The utility model belongs to the field of photovoltaic component raw material inspection, and specifically relates to a photovoltaic component packaging film sampling device. Background Art

[0002] The raw materials of photovoltaic modules mainly include cells, welding ribbons, flux, glass, backplane, encapsulation film, etc. During the production process, the raw materials need to be inspected to ensure that their appearance, size, material composition analysis, etc. meet the relevant standards and requirements to ensure the quality of the raw materials is stable and meet production requirements. Due to the constraints of the shelf life of photovoltaic raw materials and the supply cycle of components, photovoltaic raw materials need to be inspected several times a month. In the production process, in order to improve production efficiency and reduce the frequency of raw material loading, the raw material supplier increases the length and weight of each roll of backboard and packaging film, so that the weight of the backboard reaches 100kg / roll, and the weight of the packaging film reaches 180kg / roll. When testing the packaging film, it is necessary to take samples from the packaging film, and the packaging film is packed in a packaging box, so an individual is required to lift the film out of the packaging box, rotate the packaging film reel, and then cut the packaging film, and then inspect the cut packaging film. Obtaining packaging film in this way greatly increases the labor intensity of material quality inspectors, and also increases the risk of being hit or pinched by the packaging film during the sampling process.

[0003] In view of this, the present utility model is proposed. Utility Model Content
