NOVELTY - Production device comprises tin-coating system for coating tin on welding strip and is internally and sequentially provided with cleaning groove, water-blowing wind cutter, soldering flux groove, hot wind cutter, tin furnace, cooling wind cutter, and transmission pair-roller on progressing direction of welding strip. The tin-coating system has front side sequentially provided with feeding system of copper base material and cutting system for cutting copper base material into welding strips on progressing direction of welding strip.    USE - Production device used for producing tin-coated welding strip for solar photovoltaic assembly.    ADVANTAGE - The production device shortens producing process and improves yield.    DETAILED DESCRIPTION - Production device comprises tin-coating system for coating tin on welding strip and is internally and sequentially provided with cleaning groove, water-blowing wind cutter, soldering flux groove, hot wind cutter, tin furnace, cooling wind cutter, and transmission pair-roller on progressing direction of welding strip. The tin-coating system has front side sequentially provided with feeding system of copper base material and cutting system for cutting copper base material into welding strips on progressing direction of welding strip. The tin-coating system has backside sequentially provided with strip storing system and no-halt coil replacing and strip-receiving system on progressing direction of welding strip. The strip storing system includes strip storing frame having front part mounted with fixed pulley group, movable pulley group, weighing pulley, and weighing block. The weighing pulley is positioned at top part of strip storing frame and is connected with mounting frame of movable pulley group through one end of sling while other end is connected with weighing block. The strip storing frame has middle part mounted with several groups of independent stored strip mounting base. Each group of independent stored strip mounting bases is respectively mounted with independent stored strip pulley groups. Each group of independent stored strip pulley group includes independent stored strip fixed and movable pulleys. The back part of stored strip frame is mounted with stored strip export guide wheel group. The welding strip sequentially permeates fixed pulley group and movable pulley group and enters into respective independent stored strip pulley group. Each welding strip in independent stored strip pulley group sequentially permeates through independent stored strip fixed pulley and independent stored strip movable pulley, and enters into stored strip export guide wheel group and into no-halt coil-replacing and strip-receiving system through stored strip export guide wheel group. The cutting system comprises cutter frame assembly mounted on cutting system frame. The cuter frame assembly includes cutter platform base, cutter frame, cutter frame pressing plate and worm bracket. The cutter platform base is fixed on cutting system frame. The two cutter frames are opposite and respectively mounted on cutter platform base. The lower cutter shaft is in transmission connection with deceleration motor. The upper cutter shaft and lower cutter shaft are in transmission connection through transmission gear. The transmission gear group includes lower cutter shaft gear, driven gear, movable shaft gear and upper cutter shaft gear.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of production device for producing tin-coated welding strip.
