1. A dual-valve automatic calibration system, comprising:
a first fluid coating unit with which fluids are coated on a first coating zone of a target circuit board;
a second fluid coating unit with which fluids are coated on a second coating zone of a target circuit board;
a primary positioner which comprises a primary X-axis positioner and a primary Y-axis positioner for movements and primary positioning of the first fluid coating unit as well as the second fluid coating unit in directions of the X-axis and the Y-axis;
a first secondary positioner which comprises a first secondary Z-axis positioner for movements, secondary positioning and automatic calibrations of the first fluid coating unit in the direction of the Z-axis, the first secondary positioner connecting to the primary X-axis positioner; and
a second secondary positioner which comprises a secondary X-axis positioner, a secondary Y-axis positioner and a second secondary Z-axis positioner for movements, secondary positioning and automatic calibrations of the second fluid coating unit in three directions of the X-axis, the Y-axis and the Z-axis, the second secondary positioner connecting to the primary X-axis positioner,
wherein the first secondary Z-axis positioner moves the first fluid coating unit in the direction of the Z-axis separately from the second fluid coating unit, and the second secondary Z-axis positioner moves the second fluid coating unit in the direction of the Z-axis separately from the first fluid coating unit.
