Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic processing equipment technology, and more specifically, relates to a welding strip flattening device for photovoltaic modules. Background Technology

[0002] In the production process of photovoltaic modules, the quality of the solder ribbon plays a crucial role in the performance and lifespan of the module. The solder ribbon not only needs to have good conductivity, but also needs to meet strict thickness and shape requirements. In order to meet the requirements of consistent solder ribbon thickness and precise shape during the assembly of photovoltaic modules, the solder ribbon usually needs to be flattened to make its surface flat and its thickness uniform. Traditional solder ribbon flattening devices often use simple molds to directly apply pressure to the solder ribbon. Due to the limitations of the structural rigidity and manufacturing precision of the equipment itself, mold deformation or displacement is prone to occur during processing. This will lead to uneven force distribution of the solder ribbon during the flattening process, thus affecting the consistency of the solder ribbon thickness and the stability of the flattening effect.
