Product Introduction

The photovoltaic ribbon wire drawing and tinning integrated production line is a high-efficiency manufacturing system designed for producing round ribbon and flat ribbon used in solar panel module assembly. This integrated solution combines fine wire drawing, induction annealing, flux coating, hot tinning, and automatic winding into one streamlined process, eliminating intermediate steps such as separate pay-off and rewinding stations.

The line is engineered for full automation with conveyor feeding and automatic material change capability, serving as the foundation for unmanned operation. With a maximum mechanical speed of 450 meters per minute, the production capacity reaches twice that of traditional equipment, allowing manufacturers to cut equipment count and workshop space by half for the same output.

Key breakthroughs include induction heating annealing (solving the traditional issues of electrical contact wear and slippage), nano-material tinning scrapers with 10x longer service life, automatic tin replenishment, and servo-controlled winding for true unmanned operation.
