Laser marking device and laser marking method for flame-retardant cable

Abstract

The invention relates to a laser marking device and laser marking method for a flame-retardant cable. The laser marking device comprises a workbench, wherein a conveying device for conveying a flame-retardant cable with a cable cladding containing laser powder is installed on the workbench; a marking head is arranged at the top of the flame-retardant cable; reflectors which incline 45 degrees relative to the horizontal plane are arranged at the front side and the rear side of the flame-retardant cable, and the reflectors are installed at the lower part of the marking head; the marking head is connected with a front-back adjusting device; the front-back adjusting device is connected with an up-down adjusting device; and the bottom of the up-down adjusting device is fixed to an optical fiber laser marking machine cabinet. According to the laser marking device and the laser marking method, a flame-retardant cable code does not generate other harmful substances, only the laser powder added into the flame-retardant cable cladding is used for rapid marking and color changing, smoke or peculiar smell is avoided, the laser-marked flame-retardant cable code has the indelible characteristic, under reflection of the double-faced reflectors, rapid and convenient marking is carried out on two sides of a cylindrical cable, and the problem that specific coding information cannot be inquired due to the fact that one side of the cable is shielded after use is avoided.

Description

technical field [0001] The invention belongs to the technical field of laser marking, and in particular relates to a flame-retardant cable laser marking device and a marking method thereof. Background technique [0002] In the field of industrial consumer goods, flame-retardant cable marking methods are mostly inkjet coding or UV laser marking. When inkjet coding is used, ink is used as the main consumable, and the usage is large. The ink is sensitive to temperature changes and when the air humidity is not constant. The nozzles of inkjet printers are prone to blockage, leakage, dripping, popping, etc., and produce sewage discharge, and the adhesion of inkjet codes is poor, which cannot meet the conditions of long-term traceability; when marking with 266nm-355nm ultraviolet lasers, due to the The wavelength of the laser is short, which directly destroys the molecular structure of the material, changes the properties of the material surface, and has a strong marking color cont...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a flame-retardant cable laser marking device, which can keep the flame-retardant cable surface after coding with the original flame retardancy, and has no peculiar smell and smoke, and solves the problem of flame-retardant cable laser marking. The existence of marking codes destroys the flame retardancy of flame-retardant cables and a large amount of smoke and ink printing is not environmentally friendly, pollutes, and has poor adhesion
