The invention provides a full-automatic intelligent 
metal template paint spraying device which comprises a control panel, a paint 
solvent pool, a spraying head, a 
water curtain plate, an 
air channel,an exhaust opening, a waste discharging draught fan and an intelligent 
metal paint spraying device. The spraying head is arranged at the lower portion of the 
water curtain plate. By means of the full-automatic intelligent 
metal template paint spraying device, due to the arrangement of the spraying head, the 
water curtain plate, the 
air channel, the exhaust opening, the waste discharging draught fan and the intelligent metal paint spraying device, paint spraying can be better detected and controlled, according to the characteristic of a first band-pass filter with the sending 
frequency band center at the first frequency position, 
voltage signals received from a current-
voltage converter are simplified, the 
corrosion resistance effect is higher, the paint spraying uniformity is enhanced, theworking efficiency is improved, paint is saved, spraying is even, the product maintenance rate is low, operation is simple, the structure is convenient to use and practical, the intelligence degree is improved, good firmness and 
radiation resistance are achieved, the electric insulation performance is improved, the 
aging resistance performance is high, the work efficiency is improved, and therefore function diversity is completed, and the best use effect is achieved.
