C) when needing to carry out pcb board positioning printing, control system control electric control gear action, scraper base is made to moving down
After moving certain altitude, control system control electric Proportion valve, and make cylinder promote scraper base to push；
D) when the pressure and the pressure of set-up of control system that scraper base pushes have deviation, control system controls electric ratio
Valve adjusts aeration ratio；
E when) scraper base down force pressure reaches suitable state, control system control X, Y-axis mobile device control scraper head are opened
Begin to print.
2nd, silicon slice printer pneumatic type scraper head controlling method according to claim 1, it is characterised in that described automatically controlled
