Problems solved by technology

[0002] In the field of powder spraying, the metal workpiece is generally transported by a suspension system suspended on the top. In powder spraying, the principle of electrostatic adsorption is generally used. The suspension system is generally grounded. When the metal workpiece is normally connected to the suspension system, the metal workpiece can be kept. In the grounding state, if the metal workpiece is not well suspended, it is very easy to cause the phenomenon of discharge and ignition, and the powder has a little ignition energy. When the ignition energy exceeds the ignition energy of the powder, it is easy to cause a fire and cause an accident.

Abstract

The invention discloses a mobile online resistance detection system for electrostatic powder spraying. The system comprises a resistance detector and a contact electric brush assembly. The contact electric brush assembly can form surface contact with a metal workpiece suspended on a suspension assembly in a moving process. The resistance detector is connected to the suspension assembly and the contact electric brush assembly. The resistance detector, the contact electric brush assembly, the metal workpiece and the suspension assembly form a contact resistance detection loop. The resistance ofthe contact resistance detection loop can be detected in relative movement through the resistance detector. During working, one end of the resistance detector is kept communicated with the metal workpiece by the contact electric brush assembly; the resistance value between the suspended metal workpiece and the suspension assembly can be monitored on line through the resistance detector so as to judge whether the metal workpiece is normally communicated with the suspension assembly or not; when poor contact occurs, treatment can be conducted in time, a sparking phenomenon is reduced, and safetyof a powder spraying system is improved.

Description

technical field [0001] The invention relates to the field of powder spraying, in particular to a mobile online resistance detection system for electrostatic powder spraying. Background technique [0002] In the field of powder spraying, the metal workpiece is generally transported by a suspension system suspended on the top. In powder spraying, the principle of electrostatic adsorption is generally used. The suspension system is generally grounded. When the metal workpiece is normally connected to the suspension system, the metal workpiece can be kept. In the grounded state, if the metal workpiece is not well suspended, it is very easy to cause discharge and ignition, and the powder has a little ignition energy. When the ignition energy exceeds the ignition energy of the powder, it is easy to cause a fire and cause an accident. Contents of the invention [0003] The purpose of the present invention is to at least solve one of the technical problems in the prior art, to pro...
