PURPOSE: A screen printing device is provided to confirm an alignment key and a printing surface while a vision system is fixed on the printing surface of a substrate and to align at high precision. CONSTITUTION: A screen printing device comprises a turn table(210), a substrate loading unit(230), a substrate aligning unit(240), a screen printing unit(250), and a substrate unloading unit(260). The turn table includes four substrate fixing units(211,213,215,217) arranged in top, bottom, left, and right sides respectively and rotates in a clockwise or a counterclockwise. The substrate loading unit is positioned in a first direction of the turn table and loads a substrate(ST) on one of the substrate fixing units. The substrate aligning unit is positioned in a second direction of the turn table and aligns the substrate fixed to the substrate fixing unit by the substrate loading unit. The screen printing unit is positioned in a third direction of the turn table and performs printing screen on the substrate in which the alignment is completed. The substrate unloading unit is positioned on a fourth direction of the turn table and unloads the substrate in which the printing screen is completed. |
