Fig. 1 is the schematic diagram of the embodiment of the invention one;
Fig. 2 is the schematic diagram of the embodiment of the invention two.
Among the figure, 1 is starting point, and 2 is second point, and 3 for thirdly, and 4 is the 4th point, and 5 is the 5th point, and 6 is the 6th point.
The specific embodiment
Below in conjunction with the specific embodiment the present invention is done a step explanation.
Described shutoff-free laser vector text-image continuous coding mode, comprise: the luminous point coordinate that at first obtains the vector picture and text, luminous point Coordinate Conversion with the vector picture and text is an electrical quantity then, according to the deflection of electrical quantity control vibrating mirror driver driving X, Y eyeglass, accurately controls the luminous point coordinate.
The account form of obtaining accurate point coordinates is:
X＝f*tgα Y＝f*tgβ
Wherein, α, β are the galvanometer deflection angle, and f is the focal length of field mirror.
The maximum deflection angle and the voltage of galvanometer are linear, accurately control the luminous point coordinate by the control voltage signal.
Set 2 points in a bidimensional coordinate plane, its coordinate is: (x0, y0), (x1, y1), galvanometer is realized the process that the A point is ordered to B by deflection angle to B to A.A point coordinates x0 is exactly the amount of deflection of galvanometer in X-axis, and y0 is exactly the amount of deflection of galvanometer in Y-axis;
Calculate the coordinate of the point of A point to the path that B is ordered by the track mathematical algorithm, coordinate figure is exactly the amount of deflection of galvanometer.
Galvanometer control laser is rapidly inswept between the starting point of the end point of each vector picture and text and next vector picture and text, and laser is not done shutoff in rapidly inswept process.
The speed that laser is inswept was determined according to the reaction time of different material for laser light, generally speaking the speed for coloured paper external packing laser need reach 1000mm/s, for its speed of aluminium film is 400mm/s, for other metal material as its speed such as copper, stainless steel all about 200mm/s, if different its required speed of energy of lasers also can be different certainly.Beat sign indicating number based on the single line bar, too fast speed can not left a trace.
Embodiment one, make a call to the situation of a word, with common coloured paper is base material, with reference to Fig. 1, with letter " A " is example, says simply, and laser begins to beat sign indicating number from the starting point 1 of letter " A ", the first stroke gets to 1: 2 from starting point 1, does not then do to be interrupted directly to make a call to second and get to thirdly 3 from 1: 2; To thirdly 3 dozens intact, two not have continuously the stroke made a decision economy-combat finish, 3 intermediate transit points in fact thirdly, next just will be through making a call to the 3rd behind the minor tick, from i.e. 3 to the 3rd the starting point promptly the 4th: 4 thirdly of second terminal point, do not leave a trace at interval for making inswept this of laser, adopt the speed of 5000mm/s inswept, laser arrives the 4th: 4 back speed and returns to the speed of normally beating sign indicating number and continue to make a call to the 3rd to the 5th: 5, has beaten the 5th: 5 yard process of beating of promptly finishing letter " A ".
Embodiment two, beat the situation of a plurality of words, also be to be base material with common coloured paper, owing to code printing method and two words that two words are above are in full accord, therefore the sign indicating number process of beating of a plurality of words only is described as representative with two words in the present embodiment, with reference to Fig. 2, with letter " AB " is example, say simply, the sign indicating number process of beating of previous letter " A " is with reference to embodiment one, beaten the 5th: 5 finish letter " A " beat the sign indicating number after, laser need jump to i.e. the 6th: 6 continuation of starting point of letter " B " and down beat, need neither close laser equally in this course and not leave a trace at substrate surface again, it is inswept that laser adopts the speed of 7000mm/s for this reason, promptly repeats the embodiment one described coded program of beating after jumping to the 6th: 6.Word of a word like this repeats to beat the continuous sign indicating number of beating that sign indicating number can realize with laser the vector picture and text not being had the shutoff formula.
