Abstract

An ultraviolet laser processing technology comprises the following steps: 1, preparing a marking figure; 2, layering the figure, and dividing according to the areas with a same color on an original figure to form a plurality of processing layers; and 3, marking the figure in a predetermined position on a workpiece by an ultraviolet laser according to the position information of each of the processing layers, and adjusting a laser marking parameter formula according to the color of the processing layer to change the gray scale of the marking figure in order to form figures having different gray scales and a layering feeling. The processed workpiece has a smooth surface and no accidented hand feeling, and the whole processing technology has the advantages of operation convenience, no contact, no pollution, guarantee of the appearance quality of the above processed product, and substantial improvement of the added values of the product.

Description

technical field

[0001] The invention relates to a processing technology, more specifically to an ultraviolet laser processing technology. Background technique

[0002] Due to the advantages of high marking accuracy, fast processing speed, low cost, high level of automation, no mechanical extrusion or mechanical stress damage to the processed items, laser marking machines have become more and more widely used. . When the laser marking machine is working, the laser marking machine uses a high-energy-density laser to irradiate a certain part of the workpiece to vaporize the surface material or undergo a chemical reaction of color change, thereby leaving a permanent mark.

[0003] When the existing laser marking machine is processed, carbon dioxide laser (wavelength is 10640nm) processing or fiber laser (wavelength is 1064nm) processing is often used. However, when the above two methods are used for processing, both carbon dioxide laser and fiber laser Both are thermal lasers,...

Embodiment Construction

[0012] In order to make the technical solution of the present invention more clearly expressed, the present invention will be further described below in conjunction with the accompanying drawings.

[0013] Please refer to figure 1 , the present invention provides a kind of ultraviolet laser processing technology, and this ultraviolet laser processing technology adopts the ultraviolet laser that wavelength is 355nm band, 8W terminal pump to process workpiece 10, and this workpiece 10 can be leather, boot material etc., and adopts following steps to realize :

[0014] Step 1. Prepare marking graphics on the computer. The marking graphics can be drawn on the computer, or can be scanned on the drawing to obtain graphics. When scanning, use a two-axis high-speed scanning galvanometer system and F580mm optical scanning lens to scan get the outline of the graph;

[0015] Step 2, perform layered processing on the graphics, and divide them into different modules that are spliced ​​to...
