Unlike conventional tabber stringers designed for front-busbar cells, the SL-1000 addresses the unique interconnection challenge of back contact cells where both positive and negative electrodes are located on the rear surface. This machine integrates advanced electromagnetic welding, high-precision CCD vision inspection, and SCARA four-axis robotic positioning to deliver reliable, high-throughput back contact cell string production.\u003c\/p\u003e\n\u003cp\u003eThe complete system includes A\/B dual cell loading boxes, a loading translational mechanical arm, a cell transmission table, a CCD + four-axis robot detection and positioning system, a welding transmission table, an electromagnetic welding module, welding ribbon material boxes, a welding ribbon transport mechanism, a welding ribbon positioning table, double welding ribbon gluing tables, a welding ribbon placement module, and a fully automatic unloading mechanism with conveyor belt, cell string sucker, clean paper sucker, cell string box, and clean paper box.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWorking Principle:\u003c\/strong\u003eThe loading translational mechanical arm picks solar cells from the dual cell boxes and places them onto the cell transfer station, while simultaneously collecting interleaving paper into the paper collection box. The transfer station conveys cells to the CCD detection and positioning station. The CCD camera captures coordinate information and sends it to the SCARA four-axis robot, which corrects cell orientation and places each cell precisely onto the welding transfer station. The welding transfer station features multiple independently controlled temperature zones for optimal thermal management during string welding.\u003c\/p\u003e\n\u003cp\u003eMeanwhile, the welding ribbon transport mechanism picks pre-cut solder ribbons from the ribbon material box and delivers them to the positioning table, then transfers them to the ribbon placement table. The ribbon laying mechanism and four-axis robot alternate operations to complete ribbon placement and cell stacking. The assembled ribbon-and-cell array travels from the welding transfer station to the electromagnetic welding station, where the electromagnetic welding module completes soldering. Finished cell strings are transported to the unloading station via conveyor belt, and the unloading mechanism loads strings into the cell string box with clean paper interleaving to prevent scratching.\u003c\/p\u003e\n\u003ch5\u003eTechnical
