Embodiment Construction

[0029] The present invention is described in detail below in conjunction with accompanying drawing:

[0030] In order to realize the random distribution of laser texturing, the scheme proposed in this embodiment is shown in Fig. 2, Fig. 3, Fig. 7 and Fig. 11 . The texture processing of the irregular texture points on the surface of the roller is realized by a pseudo-random delay device and a pseudo-random deflection device. That is to say, in the controllable distribution laser texturing equipment, a device whose control amount changes according to a pseudo-random signal is added to make the texturing points randomly distributed. Therefore, this equipment is also called a roller surface texturing laser processing system with controllable random distribution of texturing points.

[0031] The overall structural schematic diagram of this embodiment is the same as that shown in Figure 2. The equipment consists of three parts: the head of the machine tool, the bed of the machine t...

Abstract

A laser system for generating the roughened dots with irregular circumference on the surface of a roller is composed of a machine-tool system, a laser processing system and a pseudo-random delay unit for randomly delaying the laser output signals. Its method features that the laser output signals emitted to the surface of roller are randomly delayed in a defined time range.

Description

technical field [0001] The invention relates to a laser processing equipment and a processing method for roughening the surface of rollers, in particular to a laser processing equipment and a processing method for roughening the surface of rollers capable of processing irregular textured points. Background technique [0002] YAG laser texturing equipment is a cold roll laser processing equipment researched and developed by the Institute of Mechanics, Chinese Academy of Sciences in the 1990s, such as: Chinese patent number: ZL 92113223.9, name: "High repetition frequency modulation multi-pulse YAG laser engraving system and processing method "; Chinese patent number: ZL94220848.X, name: "Laser processing equipment for surface roughening of rolls". Figure 1 is a schematic diagram of the overall structure of the device. The equipment uses high-power laser pulses with high repetition frequency to act on the surface of the roll, and produces countless strengthened micro-pits (te...
