Screen printing facility for solar cells comprising a positioning device

摘要

The machine (10) has an up and down movable printing unit (11) e.g. rotary screen printing unit, and a printing board (13), by which a conveyor belt (14) is moved. A positioning device (15) positions and accurately aligns solar cells (16) for the unit in a position on the belt according to the position data generated at a layout of solar cells structure. The device overextends the cells from a feeding device and detects a position of the cells in the device. The position data are X- and Y-coordinates of a center point of the cells, where the belt is designed as a vacuum belt and endless belt.
