Automatic Shingled Stringer SL-30C - Shingled Solar Cell Welding Machine
The Ooitech SL-30C Automatic Shingled Stringer is a fully automatic shingled solar cell welding machine engineered for high-speed, high-precision production of shingled solar cell strings. This advanced equipment welds cut solar cells into strings by dispensing and curing conductive adhesive, then automatically collects the welded strings or transfers them directly to downstream processes.
Designed for modern shingled solar panel production lines, the SL-30C integrates multiple advanced automation technologies including PLC control, linear modules, servo motors, a precision dispensing system, a multi-zone PID temperature-controlled curing unit, and an automated discharging mechanism. The entire workflow from cell loading to string discharging is fully automatic, delivering exceptional throughput with minimal operator intervention.
The SL-30C supports a wide range of shingled cell formats including 158.75mm (1/5 and 1/6 cut), 166mm (1/5 cut), and 210mm (1/6 and 1/7 cut) cells, making it a versatile solution for manufacturers producing various shingled module configurations. With a production capacity of up to 5000 pcs/h, an overlap accuracy of ±0.15mm, and a cell breakage rate of 0.2% or less, this machine is the ideal choice for solar panel manufacturers seeking to enter or scale up shingled module production.

Technical Advantages
Why Choose the Ooitech SL-30C Shingled Stringer
High-Speed Production CapacityThe SL-30C achieves production speeds of up to 5000 pieces per hour for 158.75mm and 166mm shingled cells and up to 3000 pieces per hour for 210mm large-format shingled cells. The maximum operation speed reaches 1000mm/s, ensuring manufacturers can meet demanding production targets efficiently.
Precision Overlap ControlWith an overlap accuracy of ±0.15mm and an adjustable overlap range from 1mm to 10mm, the SL-30C ensures consistent and precise cell-to-cell overlap. This level of precision is critical for achieving optimal electrical performance and aesthetic uniformity in shingled solar modules.
Advanced CCD Vision InspectionThe integrated CCD camera detection system inspects every cell for busbar defects, missing corners, and hidden cracks before welding. Defective cells are automatically rejected, maintaining a cell breakage rate of 0.2% or less when using A-grade cells and dramatically reducing material waste.
Multi-Zone PID Temperature Curing SystemThe 6-zone high-temperature curing system uses PID temperature control with real-time monitoring to ensure uniform and reliable conductive adhesive curing. Each zone is independently adjustable, guaranteeing consistent curing quality and a post-cure tension of not less than 1.5N across varying cell types and adhesive formulations.
Precision Dispensing SystemEquipped with 2 customized glue heads and spray coating technology, the SL-30C precisely controls glue width from 0.25mm to 1mm with adjustable application volume. This ensures optimal adhesive coverage while minimizing material consumption and contamination.
Non-Stop Rotary Cell LoadingThe rotary loading system with 3 baskets (250 pcs per basket) enables continuous, non-stop cell feeding. Operators can replenish baskets without interrupting production, maximizing equipment uptime to 95% or higher.
Wide Cell CompatibilityThe SL-30C supports multiple cell sizes and cut configurations including 158.75mm (1/5 and 1/6 cut), 166mm (1/5 cut), and 210mm (1/6 and 1/7 cut) with cell thickness from 150um to 230um. This versatility allows manufacturers to produce diverse shingled module designs on a single machine.
User-Friendly Operation and MaintenanceFeaturing a touch screen HMI with intuitive interface, real-time fault alarm system, PLC and servo-based electrical control, and lifetime free software upgrades, the SL-30C is designed for easy operation and minimal maintenance downtime.
