How making that the pictograph on trendy product surface instantly is not easy to wear, prolong the attractive in appearance of product design, is the technical problem that industry needs to be resolved hurrily.
[summary of the invention]
For solving the problem of above-mentioned existence of the prior art, the invention provides a kind of laser roughening processing and typography method that is used to increase printing-ink and metal surface adhesive strength.Its process is simple, and the strong adhesion of printing ink and metal the damaged phenomenon of printed pattern literal can not occur under the normal operating position.
The process that the texturing of metal surface provided by the invention is handled and printed comprises the steps:
Clean up the undertake the printing of surface of part of metal;
Pattern, the font of needs printing are input in the laser scanner and programme, and the metal part of undertaking the printing of is positioned on the workbench of laser scanner;
Start laser scanner, laser beam scans on the metal part surface of undertaking the printing of according to program, make metal undertake the printing of part surface texturing and form concave surface;
Again printing treatment is carried out on the metal surface that part forms concave surface of undertaking the printing of;
At last, carry out drying according to the printing ink configuring condition and handle, form the product of finishing.
Preferred version of the present invention, the wavelength of described laser scanner output is: 1030nm～1120nm; The power output of laser scanner is greater than 5W.
The undertake the printing of laser scanning and being printed on the same equipment on part surface is carried out for metal, and laser scanning and printing process are finished in a clamping location.To guarantee its positioning accuracy, make the position of laser scanning and print full weight and close.
The concave surface that metal is undertaken the printing of and formed behind the surface texturing of part, its concave surface degree of depth should be controlled between 0.005～0.02mm, piles up to avoid printing-ink.
The present invention earlier scans irradiation to undertake the printing of position that the part surface needs printing of metal according to the pictograph of printing with laser beam before printing, make it change metal part surface Surface Physical characteristic of undertaking the printing of, and makes its surface texturing.The part surface is increased surface roughness by texturing because metal is undertaken the printing of, reduce ink surface tension, increased printing-ink in this surperficial wellability, and make this metal undertake the printing of the real surface on part surface long-pending relatively not the real area before the texturing increase so that improved the adhesive strength of printing ink.
The formation of the many small concave surfaces in part surface makes that the printing ink after the printing is embedded in this concave surface because metal is undertaken the printing of.After wearing and tearing after a while, printing-ink lug boss branch is worn, but is embedded in still complete being kept on the metal and being difficult for being worn of the pictograph of concave surface, thereby has guaranteed the integrality of product printed pattern literal.Make printed pattern literal long-term existence in the metal lip-deep purpose of part of undertaking the printing of but so just reached.
[description of drawings]
The present invention is further illustrated below in conjunction with drawings and Examples, wherein:
Fig. 1 is the undertake the printing of cut-away illustration of part of laser pre-irradiation metal;
Fig. 2 is the undertake the printing of cut-away illustration of part of laser irradiation back metal;
Fig. 3 is the undertake the printing of cut-away illustration of part of printing back metal;
Fig. 4 is the undertake the printing of cut-away illustration of part of wearing and tearing backs metal.
[specific embodiment]
As Fig. 1, Fig. 2, shown in Figure 3, the process that the texturing of the metal surface of preferred embodiment of the present invention is handled and printed comprises the steps:
Step 1: at first, metal undertaken the printing of, and part 3---the greasy dirt on phone housing surface cleans up.
Step 2: pattern, the font that will need to print are input in the laser scanner 1 programmes, and metal part 3 clampings of undertaking the printing of are positioned on the workbench (not shown on the figure) of laser scanner.
Step 3: start laser scanner 1, laser beam 2 scans on metal part 3 surfaces of undertaking the printing of according to program, make metal undertake the printing of part 3 surface texturing and form many small concave surfaces 5.The wavelength control of laser scanner 1 output is between 1030nm～1120nm; And the power output of laser scanner is greater than 5W, as adopting 8W or 15W constant power.After the laser scanning texturing, the undertake the printing of concave surface degree of depth on part 3 surfaces of metal should be controlled between 0.005～0.02mm, piles up to avoid printing ink.
Step 4: printing treatment is carried out on metal part 3 surfaces of undertaking the printing of, promptly select as required: bat printing, silk-screen, treatment process such as spray paint.
