VARIABLE ELECTROSTATIC SPRAY COATING APPARATUS AND METHOD |
摘要 |
A liquid coating is formed by spraying drops of liquid onto a substrate or a transfer surface from an electrostatic spray head that produces a mist of drops and a wet coating in response to an electrostatic field. During spraying, the electrostatic field is repeatedly altered to change the pattern deposited by the drops. The wet coating can be contacted with two or more pick-and-place devices that improve the uniformity of the coating. |
