1.1 Solar cell type: 156-158.75mm, 166mm, 182mm, 210mm
1.2 Solar cell size limit: (39 to 156)*156mm, (1/3 166mm, 1/2 166, and full 166)*166mm, (1/2 182 and 1/3 182)*182mm, (1/2 210 and 1/3 210)*210mm
1.3 Solar cell thickness: 160-300μm
1.4 Bus bar number: 5-13BB (Need to change something on machine)
Note:9BB-13BB (Welding ribbon must be flat, the width 0.6-0.9mm)
2. Welding ribbon
2.1 Welding ribbon type: flat( leaded or lead-free)
2.2 Welding ribbon width: 0.6-2.0mm
2.3 Welding ribbon thickness: 0.18-0.32mm
Note: ≤1/3 whole cell should use 1.1-1.2mm width welding ribbon.
3 Cells String
3.1 Maximum length: 2000mm, accuracy ± 1mm
3.2 Cell spacing: 1.5-10mm adjustable, accuracy ± 0.3mm
3.3 Head and tail welding tape extension length: the length can be set independently at the beginning and end, the
range is 0-15mm
4 Welding
4.1 Welding method: infrared tube
4.2 Welding machine exposure ratio (piece): The width of welding ribbon minus the width of grid line is less than 0.2mm, less than 4%; 0.2mm-0.3mm, less than 3%; more than 0.3mm, less than 0.3%.
4.3 The welding tension is not less than 1.5n × the width of the main grid line, which depends on the quality of the cell.
5 Operating Efficiency
5.1 Up time ≥ 95% (unplanned downtime of equipment / 24H), unplanned downtime refers to equipment failure or abnormal downtime.
2.5.2 Fragmentation rate ≤ 0.2% (A grade solar cell).
6 Capacity
It can weld 1200 pcs solar cell per hour.
