Abstract
The invention discloses a kind of method of big width laser engraving, using adjustable scanning amplitude and width galvanometer scanner high speed characteristics, continuous scanning engraving is carried out in the efficient working range of galvanometer, galvanometer continuous relative motion under the control of platform, so as to form the carving area of one full line of covering, then scanning engraving next line, the processing step that engraving terminates is scanned up to whole figure.The present invention is reduced because of the error that light channel structure and mechanical precision and motion control reason are produced using continuous scanning engraving process, is improved service life of equipment.The splicing vestige produced during the clearance-type engraving large format figure of galvanometer fixed amplitude partition domain can be avoided and reduced, product quality is improved, while improving production efficiency.
Description
Technical field
Engraving is continuously scanned the present invention relates to the laser in a kind of laser-engraving technique field, more particularly to middle large format face
Process.
Background technology
Currently, the product quality that big width laser engraving is produced obtains being widely recognized as market, but existing skill with characteristic
The production efficiency of art is low to form larger obstruction to large scale application.Marking on the fly technology is just in small data
Amount, streamline is worked continuously mode, it is impossible to eliminate the splicing vestige carved to large format figure partition domain.Inkjet technology is
Scan line by line, but ink gun is that the width of ink-jet, i.e. a line is fixed to fixed array simultaneously.Because galvanometer can only be
One is relatively fixed and less operated within range, and the area of laser institute engraving pattern is limited to, and dimension of picture must shake
It is many that swashing for large format pattern is realized using the method for carving area is spliced in order to realize that big width laser is carved in the range of mirror
Light is carved, that is, after the local figure for carving a region, is moved to next carving area and is carved, and so circulation completes complete
The engraving of portion's figure.Due to being that clearance-type is moved, production efficiency is very low.And due to optics, light channel structure, machinery essence
Degree, the presence of motion control equal error, this joining method can produce different degrees of lapping defect problem in process of production, influence
Product quality；Also, this clearance-type motion also has considerable influence to service life of equipment.
The content of the invention
Technical problem solved by the invention is to overcome the defect of prior art there is provided a kind of laser of significantly picture is continuous
Scan the process of engraving.
The invention provides a kind of method of big width laser engraving, including following processing steps：
The sweep amplitude and width of galvanometer are set according to the amplitude for the significantly picture for intending laser engraving；
The high speed characteristics of galvanometer scanner are made full use of, continuous scanning engraving is carried out in the efficient working range of galvanometer；
Galvanometer is continuously moved under the control of platform, so as to form the carving area of one full line of covering, then scanning is carved
A line is inscribed, until whole figure scanning engraving terminates；
Galvanometer is when scanning engraving pattern, and itself is moved in continuous opposite piece always, at the end of Current Scan task,
Start scanning engraving in next scanning area immediately, realize the continuous engraving that do not stop；
Described continuous relative movement for workpiece is motionless and platform is moved with galvanometer, or galvanometer is motionless and platform with
Workpiece is moved；
Described vibration mirror scanning, no fixed array, with the difference of hardware configuration, can adjust the amplitude and width of scanning,
The width maximum of scanning engraving a line is only limited by vibration mirror scanning amplitude range, and galvanometer working range is bigger, sweep length
Maximum can be bigger.The minimum value of sweep length is the size of a laser engraving point.
Due to using above-mentioned technical scheme, the present invention has following beneficial effect：
Reduce because of the error that light channel structure and mechanical precision and motion control reason are produced, improve service life of equipment.Keep away
Exempt from and reduce the splicing vestige produced during the clearance-type engraving large format figure of galvanometer fixed amplitude partition domain, improve product matter
Amount, product aesthetics is good, and globality perception is strong；Production efficiency is improved simultaneously.
Brief description of the drawings
Fig. 1 Fig. 2 is the production technique structure figure of the present invention.
In figure, 1- galvanometers, 2- workpiece, 3- galvanometers move forward and backward direction, 4- galvanometers or so amplitude moving direction
Embodiment
Referring to the drawings, the present invention is further elaborated with reference to following examples：
As shown in Figure 1, 2, a kind of method of big width laser engraving of the invention, including following processing steps：
The sweep amplitude and width of galvanometer are set according to the amplitude for the significantly picture for intending laser engraving；
The high speed characteristics of galvanometer scanner are made full use of, setting is since a direction in the efficient working range of galvanometer
Carry out continuous scanning engraving；
Galvanometer continuously travels forward under the control of platform, so as to form the carving area of one full line of covering, then sweeps
Engraving next line is retouched, until whole figure scanning engraving terminates；
Galvanometer is when scanning engraving pattern, and itself is moved in continuous opposite piece always, at the end of Current Scan task,
Start scanning engraving in next scanning area opposite direction immediately, realize the continuous engraving that do not stop；
Described continuous relative movement for workpiece is motionless and platform is moved with galvanometer, or galvanometer is motionless and platform with
Workpiece is moved；
Described vibration mirror scanning, no fixed array, with the difference of hardware configuration, can adjust the amplitude and width of scanning,
The width maximum of scanning engraving a line is only limited by vibration mirror scanning amplitude range.The minimum value of sweep length is a laser
Carve the size of point.
The method carved using above-mentioned big width laser, it is possible to decrease light channel structure, mechanical precision, motion control equal error,
Improve service life of equipment；Avoid and reduce the splicing produced during the clearance-type engraving large format figure of galvanometer fixed amplitude partition domain
Vestige, improves product quality, and product aesthetics is good, and globality perception is strong；Production efficiency is improved simultaneously.
Finally it should be noted that：Above example only not limits technology described in the invention to illustrate the present invention
Scheme；Therefore, although this specification with reference to each above-mentioned embodiment to present invention has been detailed description, this
Field it is to be appreciated by one skilled in the art that still can be modified to the present invention or equivalent substitution；And all do not depart from this
The technical scheme of the spirit and scope of invention and its improvement, it all should cover in scope of the presently claimed invention.
