Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic film detection, in particular to a photovoltaic film welding detection fixture. Background Art

[0002] Photovoltaic welding ribbon is an important raw material in the welding process of photovoltaic modules. The quality of the welding ribbon will directly affect the current collection efficiency of photovoltaic modules and have a great impact on the power of photovoltaic modules. The welding ribbon must be firmly welded in the process of connecting the cells in series to avoid the occurrence of false welding. The hardness of the welding ribbon generally depends on the thickness of the cell and the welding tool. Manual welding requires the state of the welding ribbon to be as soft as possible. The soft welding ribbon will be in good contact with the cell after the soldering iron passes through. The stress generated during the welding process is very small, which can reduce the fragmentation rate. However, the tensile strength of the welding ribbon that is too soft will be reduced and it is easy to break. For automatic welding process, the welding ribbon can be slightly harder, which is conducive to the straightening and pressure welding of the welding ribbon by the welding machine. The welding ribbon that is too soft is easy to deform when welded by the machine, thereby reducing the yield rate of the product.

[0003] After searching, Chinese patent application number CN 106985096 A discloses a photovoltaic film welding detection fixture, including two support rods perpendicular to the base connected by bolts at the upper end of the base. The invention can be automatically tensioned under the tension of the tension spring, without manual tensioning, thereby reducing damage to the photovoltaic film. The photovoltaic film is convenient and labor-saving to lay flat, and the photovoltaic film can be wound on a rotating drum. If the product inspection indicators are qualified during the inspection process, the photovoltaic film can be reused and continuous inspection can be carried out. However, when the comparative document is used in practice, since the photovoltaic film is suspended in the environment when it is tensioned, it will shake if there is wind or other conditions, which is not convenient for welding inspection. A structure that can be tensioned and flattened at the same time is needed to improve the convenience and inspection efficiency of the fixture. Therefore, it is necessary to design a photovoltaic film welding inspection fixture. Utility Model Content
