Used for automatic multi busbar PV cell soldering
MBB cell stringer machine of AM050F is a crystalline silicon solar cell string production machine combining functions of soldering and lossless cutting. The cell stringer can be applied to 3BB-16BB cells of 161-230mm. The cutting mechanism can cut half and 1/3 cells without material loss, and the soldering mechanism can be repurposed to produce 1/3, half and full cells of 161-230mm. The stringer machine adopts advanced automation technologies in terms of PLC, servo motor, four-axis industrial robot and machine vision to realize automatic production of cell strings.
