Example Embodiment

[0029] The present invention will be described in detail below in conjunction with the drawings:

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

[0031] The overall structure diagram of this embodiment is the same as that shown in Fig. 2. The equipment is composed of a machine head, a machine bed and a control cabinet, and has a struc...

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...
