Equipped with built-in tension control algorithms, this solution meets the key performance requirements of the equipment as follows:
· Maximum breaking force of fine wire: 5N; maximum winding tension ≤ 2.1N
· Indirect tension control; tension fluctuation shall not exceed ±0.1N to ensure stable winding without wire breaking
· Unwinding active force less than 0.6N with continuous torque control mode
· Multi-channel temperature control: temperature deviation of heating furnace less than ±5℃; temperature deviation of heating film less than ±2℃
The cell strings welded by the stringer are automatically arranged into cell arrays via visual positioning in accordance with process dimensional requirements, layup orientation and sequence.
· Linear motors are adopted, delivering a maximum speed of 2 m/s (1 second faster in cycle time than traditional manipulators).
· Design cycle time: ≤30 s per piece for conventional modules; ≤53 s per piece for half-cut modules.
· String spacing accuracy: ±0.3 mm with mechanical positioning plus CCD vision (excluding inherent errors of cell strings).
· Distance tolerance between cells and glass edge: ±1 mm.
· Compatible module types: conventional 60-cell, 72-cell, half-cut, double-glass half-cut, MBB, shingled modules, etc., with one-click switching.
