[0015] The intelligent robot for wire harness welding described in the present invention uses a moving rope, a moving sleeve, a cleaning brush and a spring in combination. The moving sleeve moves upward to drive the moving rope to relax. The loosening of the moving rope allows the cleaning brush to cling to the inner wall of the cover plate under the action of the spring, so that the cover plate can be cleaned by the cleaning brush during the process of rotating out to prevent impurities from adhering to the cover plate, thereby reducing the amount of impurities falling on the wire harness during welding and causing adverse effects on the wire harness welding.

[0031] Specifically, a second one-way valve 31 is fixedly installed on the blowing pipe 34. The second one-way valve 31 realizes one-way flow of gas from the outside of the airbag 26 to prevent the gas extracted by the vacuum fan 10 from flowing out of the blowing pipe 34 when the vacuum fan 10 is working.
