SOLAR TABBER AND STRINGER MACHINE

ZST-SS-2600 SOLAR TABBER AND STRINGER MACHINE

1. Product Description

ZST-SS-2600 string soldering machine is an automatic equipment that welds the well-tested cells into strings through interconnection bars, and sorts and collects the soldered cell strings. The equipment adopts various advanced automation technologies such as PLC, SCARA robot, servo motor, infrared welding system, etc., to realize fully automatic processing from battery chip feeding to cell string discharging.
