Product Introduction
The PV Busbar Ribbon Integrated Drawing Rolling Tinning Production Line is a complete turnkey solution designed for producing high quality tin-coated copper ribbons used in solar panel manufacturing. The line integrates six core processes - wire drawing, calender rolling, flat drawing, annealing, tin coating and take-up - into one continuous production system, delivering consistent ribbon quality required by modern photovoltaic module assembly.
Each mechanical unit is built as an independent module that can be relocated or recombined according to plant layout requirements. The main motor runs through a variable frequency drive with stepless speed adjustment from 0 to 150 m/min, with current speed shown on the touch screen. The drawing pay-off, calender, annealing and take-up motors each carry their own dedicated VFD. Tension bar movement drives a precision resistor, and the resistance signal is calculated by the PLC in real time, which commands each VFD to instantly adjust motor speed. This keeps the tension bar stable, maintains optimum line tension, and ensures uniform ribbon diameter throughout the run.
The line targets manufacturers of solar cell interconnect ribbons and bus ribbons supplying module production plants running PERC, TOPCon, HJT, IBC, MBB, shingled and similar cell technologies.
