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.

Basic Information |
Uptime |
≥95% | (1 - unscheduled downtime/24H), unscheduled downtime refers to the time when the equipment malfunctions or is shut down unexpectedly. | |
Speed | 18Xmm cells: 3BB-12BB Half-cut≥6800 strips/hour 18Xmm cells: 13BB-20BB Half-cut≥6000 strips/hour
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. | ||
Cell Cracks |
161mm to 171mm cells: Mono-Si ≤0.2%; 171mm to 230mm cells: Mono-Si ≤0.25%; | Popular Grade A cell, thickness ≥170μm Cell crack ratio = (cracked cells + micro-cracked cells)/total number of soldered cells × 100% | ||
