Boost Your Solar Panel Production with MBB PV Cell Soldering Stringer - Advanced Technology for Streamlined Manufacturing Processes

Main Function

MBB PV Cell Soldering Stringer is a fully automatic machine used to non-destructively cut the mono-Si or poly-Si cells and then solder them into a string. Normally it can work with 156-230mm (3BB-20BB) cells. The cell cut module can cut cells in half, or cut cells into three strips after upgrade. The soldering module can be upgraded for 156-230mm (full, half-cut, 1/3-cut) cells. With the use of PLC, servo, SCARA robot, industrial image processor system and other advanced automation technology, the entire process from cell feed to string outlet is fully automated.
