Abstract

The present invention provides an expansion structure for a stringer, comprising a stringer and an expansion terminal welder, the expansion terminal welder being connected to the rear end of the stringer discharge via a string cutting module. The expansion structure of the stringer of the present invention utilizes the string cutting module to expandably connect the stringer and the terminal welder, enabling various modules such as a 36BB multi-ribbon stringer, a terminal welder, and a tape laminating module to perform various functions, such as string welding of BC cells and conventional cells, laminating cells between cells, and welding busbars at the ends of cell strings. This provides a rich functionality and a wider range of applications, allowing customized module splicing as needed.
