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. ##### Technical Specifications ###### Main Performance Parameters | Parameter | Specification | | --- | --- | | Inlet Wire Range | 1.5 - 3.5 mm copper round wire | | Finished Ribbon Thickness | 0.25 - 0.5 mm | | Finished Ribbon Width | 2.5 - 8.0 mm | | Maximum Mechanical Speed | 150 m/min | | Pay-off & Drawing Motor | 20 HP induction motor | | Calender Rolling Motor | 15 HP AC motor with tension type VFD | | Flat Drawing Motor | 5.5 HP AC motor with tension type VFD | | Annealing Drive Motor | 2 HP AC motor with tension type VFD | | Annealing Transformer | 65 KVA autotransformer, full wave rectified DC output | | Take-up Motor | 3 HP AC motor with tension type VFD | | Traverse Motor | 0.75 KW servo motor | | Total Installed Power | Approx. 130 KW | | Tin Coating Thickness | 0.01 - 0.035 mm | | Temperature Control Accuracy | ±5°C with over-temperature alarm | | Tin Pot Capacity | 180 kg | | Electric Heating Power | 12 KW tubular heater | ###### Machine Composition | Unit | Quantity | | --- | --- | | Swing Arm Pay-off Machine | 1 set | | 7-Die Gear Intermediate Drawing Machine | 1 set | | 180 Rolling Mill | 2 sets | | Rolling Mill External Oil Cooling Station | 1 set | | 500 Single Die Flat Drawing Machine | 3 sets | | 65 KVA Annealing Machine with Chiller | 1 set | | Hot Air Drying System | 1 set | | Air Knife Hot Tinning Machine | 1 set | | Servo Digital Up-lead Wire Storage Rack | 1 set | | 25 kg Twin Spindle Take-up Machine | 1 set | | Electrical Control Cabinet | 1 set | | Single Arm Operation Box | 1 set | | Interconnection Cables & Pneumatic Rack | 1 set | ##### Technical Advantages ###### Precision Drive and Tension Control - Stepless speed regulation 0 to 150 m/min controlled by VFD with HMI display - Independent VFD on every functional section, each linked to a precision resistor tension sensor - PLC real-time computation instantly corrects motor speed to keep tension bar stable - Closed-loop control delivers uniform ribbon diameter and minimal yield loss ###### Robust Drawing and Rolling Section - 7-die four-axis horizontal gear drawing with tungsten carbide spray welded capstans - Three-layer integrated capstan design, two interchangeable plus one final dedicated capstan - 180 mm tungsten carbide rolling rolls, air cooled with internal water circulation - Online laser detection with closed-loop control automatically adjusts rolling gap during operation - Dovetail slide alignment at inlet and outlet for precise positioning ###### Stable Annealing Performance - Short circuit full-wave DC annealing, 45 KW 0-35V power supply auto-tracking line speed - Aluminum annealing tube with anodized door opening structure, nitrogen protected - Circulating water plus air cooler temperature control - Hard wearing electrical bakelite guide wheels for long service life ###### High Quality Tin Coating - 12 KW tubular electric heater with ceramic fiber insulation for uniform heating - Titanium plate welded tin pot, 180 kg capacity, stress relief annealed - Titanium press rolls resist tin adhesion and wear - Precision air knife with stable balanced air supply for uniform tin thickness - Dual-groove PP flux tank with felt drip application and shortage alarm - Automatic tin feeding system with low level alarm - Centralized fume extraction over flux and tinning zones ###### Reliable Take-up System - Servo driven up-lead storage with 2.5 m vertical wire storage space - 4 m storage rack provides up to 35 seconds for non-stop bobbin change - 750 W servo motor traverse with ball screw and gear belt for stable wire laying - Twin spindle take-up with segmented main shaft for both large and small bobbins - Two sets of traverse and take-up enable non-stop reel change ###### Premium Component Selection - Bearings from NSK, JNS, HRB brands - Habasit flat belts and Nitta timing belts - Wannan series motors with sinusoidal servo and PLC - Sinusoidal brand HMI touch screen ##### Product Applications The production line is dedicated to manufacturing tin-coated copper interconnect ribbons and busbar ribbons used in crystalline silicon solar module assembly.
