Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Specific implementation of the invention is described in detail below in conjunction with specific embodiment:
Embodiment one:
Attached drawing 1 is the implementation flow chart of the control method of the laser processing rotary-cut scanning track shown in embodiment one.Implement
The control method of laser processing rotary-cut scanning track shown in example one is suitable for controlling the electronic equipment of laser processing rotary-cut scanning
In, processor is set in electronic equipment, and rotary-cut when being laser machined with controlling scans track.For ease of description, only show
Go out part related to the embodiment of the present invention, details are as follows:
Step S110, obtains the scale factor of sweep parameter and setting, and the sweep parameter includes becoming half collar number, wedge
Start angle, wedge angle at the end.
Sweep parameter relevant control parameter when being control laser processing rotary-cut scanning.Sweep parameter includes becoming half collar
Number, wedge start angle, wedge angle at the end.
Become half collar number and scans the spiral winding number to form scanning disc into every layer of rotary-cut；Wedge start angle is wedge rotation
Cut angle when scanning starts, the innermost circle corresponding to spiral scan trajectory；Wedge angle at the end is that wedge rotary-cut scans single layer
At the end of angle, the outmost turns corresponding to spiral scan trajectory.
Normally, rotary-cut scanning cheesing techniques by become half collar number, wedge start angle, wedge angle at the end these three
Sweep parameter controls the track of rotary-cut scanning.In entire scanning process, since rotary-cut scanning revolving speed is higher, it is difficult in required position
The output power for being accurately controlled laser is set, so the output power of laser remains unchanged.
Rotary-cut scans the controllability of track when to improve laser processing, increases new control parameter --- scale factor.Than
The example factor is the track regulation parameter of rotary-cut scanning helix, can control rotary-cut scanning helix by adjusting scale factor
Density distribution.
Scale factor can the ratio between radius increment between adjacent turn, can also the ratio between perimeter increment between adjacent turn or
The ratio between area increase can also be the control parameter of other forms.It can control rotary-cut scanning helix by adjusting scale factor
Density distribution, to improve the controllability of the scanning of rotary-cut when laser processing track.
Step S120, the wedge of each circle deflects when being scanned according to the sweep parameter and the scale factor calculation rotary-cut
Angle step.
Helix density degree in track is scanned by adjusting the adjustable entire rotary-cut of scale factor.
Specifically, when radius increment the ratio between of the scale factor between adjacent turn, according to the sweep parameter and the ratio
The example factor calculates the radius increment of each circle, and then the wedge of each circle when rotary-cut scans is calculated according to the radius increment of each circle
Deflection angle increment.
Rotary-cut scans track as shown in Fig. 2, radius increment d of the scale factor between adjacent turnrThe ratio between, if circle and circle
Between spacing be drn(drn=Rn-Rn-1, n=1,2,3 ... n), d can be regulated and controled by the Set scale factorrVariation tendency,
So that rotary-cut scanning track is adjustable.
Specifically, scale factor can make drIt is distributed according to Geometric Sequence, changes scale factor, radius increment drIt is formed
Ordered series of numbers will change, the density degree of helix will change.
For example, scale factor is the common ratio q of Geometric Sequence.When the common ratio q using Geometric Sequence is scale factor, drn=
dr1*qn, the track of rotary-cut scanning helix can be adjusted by changing q value.
After setting becomes half collar number, wedge start angle, wedge angle at the end and scale factor, by calculating rotary-cut scanning
Each circle wedge deflection angle increment, and control rotary-cut scanning means according to the wedge deflection angle increment being calculated into
Row rotary-cut scanning.If double wedge systems control the angle step that a wedge increase is calculated when individual pen rotates, another
Wedge reduces the angle step being calculated, to control deflection angle increase and decrease of the laser after wedge.
It is almost the same in the rotary-cut scanning individual pen time, in the case where laser output power is constant, inner ring unit area
On laser energy be higher than outer ring, it is possible to make the d of inner ringrBigger, i.e. the setting ratio factor makes rotary-cut scan spiral shell less than 1
Spin line outer perimeter section is closeer, and inner round portion is thinner, to achieve the purpose that optimization damages wall.
Fig. 3 be scale factor shown according to an exemplary embodiment be 0.7 when rotary-cut scan track radius change
Tendency chart.Inner radii variation faster, makes in inner ring circle segment and circle in rotary-cut scanning of the present invention track as seen from Figure 3
Between spacing it is bigger, thus reasonable distribution laser power, optimize the effect damaged to wall when playing to inner ring rotary-cut scanning.
In specific practical application, takes the rotary-cut of the present embodiment to scan the adjustable control method in track, give scale factor
Set numerical value less than 1, control rotary-cut scanning means operating, technique draws a design test, and longitudinally cutting is checked in punching on exemplar
Shape, and the value of scale factor using dichotomy is determined according to technique test effect of drawing a design, if inner round portion is compared with outer ring depth, reduce
Scale factor improves scale factor value if opposite, until obtaining suitable scale factor value.
Step S130 is scanned according to the rotary-cut that the wedge deflection angle increment carries out each circle.
Using method as described above, after obtaining the scale factor of sweep parameter and setting, according to sweep parameter and ratio
The example factor calculates the wedge deflection angle increment of each circle when rotary-cut scanning, and then each according to the progress of wedge deflection angle increment
The rotary-cut of circle scans, and the controllability of rotary-cut scanning track, makes in inner ring circle segment and circle when effectively improving laser processing
Between spacing it is bigger, thus reasonable distribution laser power, optimize the effect damaged to wall when playing to inner ring rotary-cut scanning.
