Aligns & Transports Completed Solar Cell Strings Spi-Module Lay-Up Station shown as option with Spi-Assembler The Spi-Module Lay-Up Station automatically aligns and places completed solar cell strings in position for module assembly. The Spi-Module Lay-Up Station can be implemented as an option to the Spi-Assembler 6000, or it can be used as standalone equipment. The Spi-Module Lay-Up Station includes a string unloader robot for string transport, a string aligner, and a ball table for module lay-up. When the Spi-Assembler completes a cell string, a conveyor belt positions the string for pick-up by the string unloader. The unloader transports the string to either the stack table, for visual inspection or placement in a stack, or the string aligner for alignment prior to lay-up. A tilt table aligns the string’s long axis by tilting down approximately 20° to allow the string to rest against adjustable alignment guides. After alignment, the unloader picks up the string and transports it over a ball table to the appropriate string position for placement on the module. When required, the unloader automatically rotates 180° to reverse the string polarity. A ball table with retractable pads is provided for module lay-up. The number of strings per module, the string spacing, and the orientation of each string are software programmable. Features & Benefits Provides accurate, automated string alignment to glass and other module materials Eliminates manual handling of cell strings, minimizing cell breakage, contamination and stress on solder joints Rugged design for large scale string and module lay-up Adjustable for a variety of cell sizes and string positions The number of strings per module, the string spacing, and the orientation of each string are software programmable Mechanically floating vacuum cup mounts minimize mechanical stress on the cells during pickup Ball table with pads is included for module lay-up Can be used with a Spi-Assembler or as standalone equipment
