Abstract
The present invention discloses a mobile online resistance detection system for electrostatic powder spraying, comprising: a resistance detector and a contact brush assembly, wherein the contact brush assembly can form surface contact with a metal workpiece suspended on the suspension assembly during movement, the resistance detector is respectively connected to the suspension assembly and the contact brush assembly, the resistance detector, the contact brush assembly, the metal workpiece, and the suspension assembly form a contact resistance detection loop, and the resistance detector can detect the resistance of the contact resistance detection loop during relative motion. During operation, one end of the resistance detector is kept in communication with the metal workpiece through the contact brush assembly, and the resistance value between the suspended metal workpiece and the suspension assembly can be monitored online through the resistance detector to determine whether the metal workpiece and the suspension assembly are normally connected. When poor contact occurs, it can be processed in a timely manner, thereby reducing the occurrence of sparks and improving the safety of the powder spraying system.
