Function
SS-1500 Stringer adopts IR soldering method, servo motor driving, mechanical positioning and Industrial CCD detection for defective solar cell excluding automatically. The soldering effect, such as cell spacing, cell numbers of single string, soldering temperatures and etc, can be adjusted according to requirements. SS 1500 can be integrated with automatic layup machine to achieve the composing and locating of solar cell strings on tempered glass.
Equipment Advance
- Applicable for front side and back side soldering of the cell,
- Qualified soldering effect, which approves soldering pulling testing higher than 1N/mm on cell surface (0.6*0.25mm ribbon, 180 degree pulling angle, and except HJT cell)
- Exchange time less than 120mins for changing different bus-bar number(9BB&12BB), including 30-60mins for changing tools and 30-60mins for tuning and calibrating. Exchange time less than 30mins for different cell sizes (whole cell, half cell, third cell and quarter cell) while bus-bar number fixed.
- Two Stingers requires only one operator.
- Dual Solar cell unloading basket to avoid working interruption.
- Ribbon extruding in advance before soldering.
- Pre-heating before soldering to avoid cell deformation efficiently
- Applicable for Solar cells thicker than 160um, max thickness 300um.
- Adjustable for Ribbon soldering spacing.
- Adjustable for Ribbon soldering length.
- Touchable integrated PC system can support remote assistance, we can provide online technical support for after-sales issues.
- Can be integrated with other Solar equipment conveniently.
- Remote assistance by Internet, the factory provides the network connection.
- Adjustable for Solar cell spacing 0-35mm, normally 1.5-5mm.
- No pre-heating required for Ribbon before soldering.
- No specialized engineer required for maintenance, but engineers must be trained and qualified.
- Solar cell soldering numbers per string can be set by PC.
