MBB Solar Cell Welding 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.
MBB solar cell welding 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.
(1 - unscheduled downtime/24H), unscheduled downtime refers to the time when the equipment malfunctions or is shut down unexpectedly.
18Xmm cells: 3BB-12BB Half-cut≥6800 strips/hour
18Xmm cells: 13BB-20BB
230mm cells: 3BB-12BB
Half-cut, 1/3-cut ≥6800 strips/hour 230mm cells: 13BB-20BB
Half-cut, 1/3-cut ≥6000strips/hour
The speed depends on the solder process. If the required solder time is too long, it may affect the production speed.
161mm to 171mm cells: Mono-Si ≤0.2%;
171mm to 230mm cells: Mono-Si ≤0.25%;
Popular Grade A cell, thickness
Cell crack ratio = (cracked cells + micro-cracked cells)/total number of soldered cells × 100%
