Abstract
A painting target surface of a resin bumper is painted by discharging a paint mist from a spray gun toward the painting target surface with a charged conductor arranged in contact with an opposite side to the painting target surface. The paint mist is uncharged or is charged with electric charges having an opposite polarity to that of the conductor and at a potential having a lower absolute value than that of the conductor.
Claims7
A painting apparatus for an insulator, the painting apparatus comprising:
- a conductor configured to come into contact with or proximity to a surface opposite to a painting target surface of the insulator;
- a charger configured to charge the conductor;
- and
- a paint discharger configured to discharge, toward the painting target surface of the insulator, a paint mist that is uncharged or is charged with electric charges having an opposite polarity to a polarity of electric charges of the conductor and at a potential having a lower absolute value than an absolute value of a potential of the conductor,
- wherein the charger is configured to continuously perform energization for charging the conductor while the paint discharger is discharging the paint mist toward the painting target surface of the insulator,
- wherein the charger is configured to stop the energization of the conductor after the paint discharger finishes discharging the paint mist toward the painting target surface of the insulator, and
- wherein the charger includes a neutralization unit configured to switch the conductor between a grounded state and an insulated state.
