Automatic wire feeder

Abstract

The invention relates to an automatic wire feeder which comprises a pay-off device, a wire transition device and a wire speed control device which are arranged on the wire transporting direction and the pay-off device comprises a base and a feeding seat horizontally rotating relative to the base; the wire transition device comprises a detection stand column, and a wire transition opening group moving on the longitudinal direction along the stand column and a plurality of detection switches for detecting the wire transition opening group and controlling the rotation speed of the feeding seat are arranged on the detection stand column; the wire speed control device comprises a bottom plate, and a door-shaped support is vertically connected to the bottom plate; a plurality of photoelectric sensors for sensing wiring harnesses and controlling the rotation speed of the feeding seat are longitudinally arranged on the two inner side walls of the support. The automatic wire feeder can smoothly transport pipes such as corrugated pipes, can detect the degree of twist and the transport speed of the pipes in the transport process, controls the rotation speed of the pay-off device and the transport speed of the pipes according to the degree of twist and the speed of the pipes, and avoids damaging the pipes.

Description

technical field [0001] The invention relates to the field of wire harness processing, in particular to an automatic wire feeder. Background technique [0002] In the field of wire harness processing, equipment such as pipe cutting machines need to use wire feeders to send pipes such as corrugated pipes to the pipe cutting machine for processing. In the existing wire feeder, the wound wire harness is placed on a turntable or a rotating shaft, power is applied to the wire harness, and the wire harness is released by the rotation of the turntable or the rotating shaft, and conveyed through the wire passing device. During the conveying process, because the coiled wire harness is continuously pulled, the wire harness will produce twist. When the twist of the wire harness reaches a certain level, it will affect the conveyance of the wire harness and also cause damage to the wire harness. At present, in order to eliminate the twist, usually by manual Manual operation has a low deg...

AI Technical Summary

Problems solved by technology

During the conveying process, because the coiled wire harness is continuously pulled, the wire harness will produce twist. When the twist of the wire harness reaches a certain level, it will affect the conveyance of the wire harness and also cause damage to the wire harness. At present, in order to eliminate the twist, usually by manual Manual operation has a low degree of automation, which is time-consuming and laborious; in addition, when the pipe cutting machine is cutting pipes, there will be different cutting rates, and the speed of pulling the pipes will be different, while the turntable or shaft always rotates at the same speed. Pipe release, when the traction speed is fast, the release speed of the turntable or shaft cannot keep up with the traction speed, and the pipe cutter will drag the pipe, causing the pipe to be torn or broken
