Problems solved by technology

[0003] At present, some manual tools for cold stripping processing are widely used for the processing of aviation wire harness ends, such as wire strippers, special knives and other tools. This manual processing method may cause physical damage to the wire core and reduce the strength of the wire. Mechanical strength, which affects the service life of the wire, has been unable to meet the needs of the rapid development of the modern aircraft manufacturing industry
There are also some enterprises and research institutions at home and abroad to carry out research work in this area, such as using electric heating for terminal processing, but because the insulation layer of aviation wires is high temperature and low temperature resistant wires, it is not easy to be melted, after melting It is not easy to be separated, and the processing effect is not good

Abstract

The utility model relates to a laser processing equipment for aviation wire harness ends, which relates to the field of aviation wire harness processing. The invention uses a laser to process the end of the aviation wire harness, mainly based on a nanosecond short pulse laser with a wavelength of 405nm, uses a rotating mechanism to drive the optical system, and surrounds the aviation wire harness to be processed. The goal is to realize the processing of wire stripping, window opening, slitting and regional evaporative ablation of aviation wire harness ends. In the present invention, the wire with PTFE and PVC as the insulating material is used as the material to be processed. The processing time is less than 5s, the fixed length accuracy is not more than 0.2mm, and the processing length is 3-30mm. Reliable quality, high processing efficiency, high processing accuracy, small footprint, and easy to move.

Description

Technical field [0001] The present invention relates to the field of aero harness processing, and more particularly to a aviation harness end laser processing apparatus. Background technique [0002] The wire harness is a power supply, a bridge of a communication system, an effective connection of any electronic system and communication devices, is inseparable from it. According to statistics, there is a model of a model of my country, and there is more than 1,400 wires on a plane, so the line harness processing is close to 30,000. During the wire harness assembly, the wire end processing is an essential part of the assembly production process, and the quality of the wire end processing is directly related to the reliability of product quality. At present, in the machining of automobile harness, large-scale harness manufacturers have widely used the combined length of the unit, automatic stripping, and terminal prefixed harness end production equipment. However, for aviation, spa...
