Specific implementation mode
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, below in conjunction with the accompanying drawings to the present invention
Specific implementation mode be described in detail.
A kind of laser marking method carries out laser marking using vibration mirror scanning type laser mark printing device.Vibration mirror scanning type swashs
Light marking device will wait for mark showing methods to the surface of workpiece.Under normal conditions, vibration mirror scanning type laser mark printing device has
Preset mark range, for example, the figure that the boundary of mark range is constituted is rectangle.Further, in this embodiment and the square
The length of shape is 20mm, width 20mm, i.e. the boundary of mark range constitutes square.That is vibration mirror scanning type laser mark printing device
Mark work can only be carried out in the range of the rectangle.In present embodiment, laser marking method can be applied to laser marking
In system (hereinafter referred to as system), system is first directed to the file for waiting for mark figure, secondly is needed to treat mark figure according to technique
Each spirte in shape carries out the setting of laser labelling parameter.It waits for that mark figure is two-dimentional large scale figure, that is, waits for mark figure
The size of shape is more than the mark range of vibration mirror scanning type laser mark printing device.It is described in detail below and this kind of waits for beating for mark figure
Mark method.
Fig. 1 is the schematic diagram of the laser marking method of first embodiment.Fig. 2 is the signal for waiting for mark figure of an embodiment
Figure.Laser marking method includes：
Step S110, the plane where waiting for mark figure establish the first two-dimensional coordinate system.
Specifically, the first two-dimensional coordinate system is rectangular coordinate system.Establishing the first two-dimensional coordinate system will carry out for subsequent step
Prepare, to improve working efficiency.In the present embodiment, the finished surface pair in the plane and workpieces processing where mark figure is waited for
It answers.The machining area of workpieces processing is the target area for waiting for mark figure.First two-dimensional coordinate system (X O1Y) as shown in Figure 2,
Origin is O1。
Step S130 will wait for that mark graphics decomposition is several spirtes.
Specifically, because waiting for that the size of mark figure is more than the mark range of vibration mirror scanning type laser mark printing device,
The part that vibration mirror scanning type laser mark printing device can only once treat mark figure carries out mark.System when marking, automatically
Mark inserting drawing will be waited for into several spirtes, spirte can be according to waiting for that the component part of mark figure is divided.For example,
Spirte can be circle, rectangle, triangle, letter or line segment etc..According to the first two-dimensional coordinate system, it can determine that each spirte exists
Position in first two-dimensional coordinate system.For example, the coordinate of line segment two-end-point is it is known that then known to the position of line segment.In the present embodiment,
It will wait for that mark graphics decomposition is several straightways.I.e. spirte is straightway.
Step S150, treated according to the mark range of vibration mirror scanning type laser mark printing device region where mark figure into
Row divides, and obtains several marking areas.
Specifically, wait for that the shape in the region where mark figure is identical as target area.As shown in Figure 2, mark figure is waited for
Region where shape is the region that all grid of dashed lines are constituted.According to above-mentioned mark range, the area that will wait for that mark figure is constituted
Domain is divided into several marking areas.For example, waiting for the figure that mark figure all solid lines as shown in Figure 2 sketch the contours.According to above-mentioned
Region where waiting for mark figure is divided into several marking areas by mark range, shown in marking area grid as dashed lines.
It can carry out mark respectively in these marking areas in this way.In the first two-dimensional coordinate system, pass through the top of each marking area
Point coordinates can determine the position of each marking area.It should be noted that for any marking area, and in target area
Respective sub-areas corresponds to, and the correspondence of the marking area and respective sub-areas in target area is that system is pre-set.
Above-mentioned correspondence can be proportionate relationship.
Step S170 judges whether have in each marking area according to the position of the position of each marking area and each spirte
Corresponding mark figure.
Specifically, it is mark figure to fall into the spirte of marking area or partial subgraph shape.It, can for any marking area
According to the position of the position of the marking area and each spirte, to judge whether there is corresponding mark figure in the marking area.
One marking area may be corresponding with mark figure, it is also possible to not have mark figure.When marking area has corresponding mark figure,
Should mark be carried out to the marking area.When marking area does not have corresponding mark figure, then system is not to the marking area
Mark.Comparison respectively waits for can determine that marking area in the position of spirte of mark and the position of marking area that whether there is or not mark figures.
For example, it has been observed that respectively wait for that the spirte of mark is made of straightway, and straightway is formed by putting, and in the first two-dimensional coordinate
In system, the coordinate put on straightway is in a certain range.Compare the coordinate and marking area of the point on the straightway for waiting for mark
Boundary, you can judge that this waits for whether the spirte of mark falls into marking area.
Step S190, when being corresponding with mark figure in marking area, according to the corresponding mark figure of marking area, air exercise
It marks region and carries out mark.
Specifically, it when being corresponding with mark figure in system judgement marking area, is then beaten according to the marking area is corresponding
It marks on a map shape, mark is carried out to marking area, it has been observed that marking area corresponds to the subregion on target area, therefore, to mark
Region mark is also to carry out mark to the respective sub-areas of target area.In this way, can be to the mark area of each mark
Domain mark, to complete entirely to wait for the mark task of mark figure.
Mark graphics decomposition is several spirtes by above-mentioned laser marking method, first, system, according to vibration mirror scanning type
Region where the mark range of laser mark printing device treats mark figure is divided, several marking areas are obtained.Secondly,
System judges whether there is corresponding mark figure in each marking area according to the position of the position and each spirte of each marking area
Shape.Then, when system is corresponding with mark figure in marking area, according to the corresponding mark figure of marking area, to mark area
Domain carries out mark.In this way, after system starts mark task, system is complete successively according to the corresponding mark figure of each marking area
At the markers work of each marking area, to realize the label task for entirely waiting for mark figure.Therefore, above-mentioned laser marking method
And system can wait for mark figure automatic classifying and mark to arbitrary size, arbitrarily complicated degree, do not limit and wait for mark figure
Size reduces mark difficulty, and mark speed is fast, and mark efficiency is higher.
It should be noted that the sequence of step S130 and step S150 can in no particular order, as long as before step S170
Spirte and marking area are divided.
Fig. 3 is the flow diagram of the laser marking method of second embodiment.Fig. 4 be the present embodiment pending figure with
The relation schematic diagram of current region 410.
In the present embodiment, it will wait for that mark figure is pre-set in a rectangular area.First two-dimensional coordinate system is with the rectangle
One vertex on the boundary in region is origin O1.The area of rectangular area is the integral multiple of the area of mark range.It has been observed that galvanometer
The boundary of the mark range of scanning type laser marking device is the square that length of side a is 20mm.It is waited for please continue to refer to shown in Fig. 2
Mark figure, can be by 28 times of the length of side a that the length L on the boundary of rectangular area is mark range, and width W is the side of mark range
13 times of long a, that is, it is 560mm to wait for that mark figure is located at length, and width is in the rectangular area of 260mm.
In the present embodiment, the region where mark figure is treated according to the mark range of vibration mirror scanning type laser mark printing device
The step of being divided, obtaining several marking areas, i.e. step S150 are：If rectangular area is divided into according to mark range
Dry marking area.
Specifically, the area equation of the area of each marking area and mark range.System can be facilitated rectangle region in this way
Domain is divided into N number of marking area with the area equation of mark range, wherein N is positive integer.I.e. in the present embodiment, according to square
Rectangular area can be divided into 364 grids, grid void as shown in Figure 2 by the area of the area and mark range in shape region
Shown in wire grid.One grid is a marking area, i.e. vibration mirror scanning type laser mark printing device can only once be beaten at one
It marks region and carries out mark.Such distributed approach for treating mark figure, can make system treat mark figure
Split easier, raising calculating speed.
In the present embodiment, according to the position of the position of each marking area and each spirte, judge in each marking area whether
There are the step of corresponding mark figure, i.e. step S170 to include：
Step S171 selects currently to want the marking area of mark as current region 410.
Specifically, current region 410 refers to that vibration mirror scanning type laser mark printing device is currently beating target area.System can
To select a marking area as current region 410.System can be with sequential selection marking area.It has been observed that current region 410 is answered
Should be region shown in a grid in Fig. 2.In the first two-dimensional Cartesian coordinate system, the boundary of current region 410 is straight line, and
The equation on the boundary of current region 410 is it is known that be the range that can determine current region 410 by four boundaries of current region 410.
Further, as shown in Fig. 2, the origin of the first two-dimensional Cartesian coordinate system is O1, then can determine net according to the position of grid
The absorbing boundary equation of lattice determines the absorbing boundary equation of current region 410.
In the present embodiment, it is assumed that the coordinate of four vertex A, B, C, D of the grid where current region 410 are respectively (x1,
y1)、(x2, y1)、(x1, y2)、(x2, y2), and x1、y1、x2、y2It is known that the coordinate of the point in current region 410 is (x, y), then
The equation of current region 410 is：
In above formula, the bottom boundary of current region 410 returns the lower zone in the region all, current 410 region right edge
Boundary returns the right area in the region all, mark is repeated to avoid adjacent area boundary, so that mark effect is preferable.
It should be noted that the absorbing boundary equation of current region 410 is opposite, absorbing boundary equation can be because of the setting of coordinate origin
It is different and different.
Step S172 judges whether the spirte for needing mark.
Specifically, system judges whether to need also exist for the spirte (spirte for waiting for mark) of mark.If need
The spirte of mark, then system continuously carry out mark task.If not waiting for the spirte of mark, illustrate to have waited for mark figure
It is finished through mark, system can terminate flow.
In the spirte for needing mark, step S173 is executed, selects one to wait for the spirte of mark as pending figure.
Specifically, system selects a spirte as pending figure from the spirte for wait for mark.System will determine that
The pending figure whether be current region 410 corresponding mark figure.Alternatively, system obtains mark from pending figure
Figure.
Step S174, the boundary of the coordinate and current region 410 of the endpoint of more pending figure, judges pending figure
Whether current region 410 is at least partly fallen into.
Specifically, it has been observed that pending figure is straightway.In the first two-dimensional coordinate system, the two-end-point of straightway
Known to coordinate.Therefore, system by comparing the both ends point coordinates and current region 410 of straightway absorbing boundary equation, you can judge
Whether pending figure at least partly falls into current region 410.I.e. system may determine that pending figure is at least partly to fall
Enter current region 410 or does not all fall within current region 410.System can first compare the two-end-point and current region of straightway
410 each boundary, so as to calculate straightway be except current region 410, or within current region 410, or
Person is intersected with the boundary of current region 410 (partly in current region 410).By comparing straightway endpoint and work as proparea
The absorbing boundary equation in domain 410 judges the position relationship of pending figure and current region 410, can quickly calculate at least partially in
Pending spirte in current region 410 and not in the pending spirte of current region 410, improves system operating rate,
To improve mark efficiency.
For the pending spirte intersected with the boundary of current region 410, system is then by calculating pending spirte
The intersection point of the equation of (straightway) and each boundary of current region 410 can thus calculate to be located on pending figure and work as
Figure in forefoot area 410.
As shown in figure 4, pending figure has straightway L1, L2, L3 and L4.By taking straightway L4 as an example, pass through straightway L4
Two-end-point and current region 410 absorbing boundary equation, can be easy to judge, the two-end-point of straightway L4 is in current region
Except 410.And then continue to solve the intersection point of straightway L4 and the boundary of current region 410.
It is easy to obtain the equation of straightway L4 by the two-end-point of straightway L4, it is assumed that equation is：
Y=kx+b (2)
The intersection point of straightway L4 and the boundary of current region 410, straightway L4 and area can be acquired by formula (1) and formula (2)
Two boundaries in domain are intersected, i.e., partly fall into current region 410.Assuming that the coordinate of two intersection point E, the F acquired is respectively (x1,
ye), (xf,y1), then straightway EF is the figure for falling into current region 410.It similarly, can be in the hope of straightway L2 and region
A line circle intersects, and a part of line segment GH of straightway L2 falls into current region 410.Straightway L1 is outside current region 410.Directly
Line segment L3 is in region.
When pending figure at least partly falls into current region 410, step S175 is executed, current region 410 will be fallen into
Figure as mark figure.
Specifically, system will fall into current region 410 when pending figure at least partly falls into current region 410
Figure is as mark figure.For pending figure, if at least partly falling into current region 410, system if, judges pending
Figure is that part falls into current region 410 or entirely falls in current region 410.It is entirely fallen in currently in the pending figure
When in region 410, pending figure is determined as corresponding mark figure in current region 410, such as above-mentioned straightway L3.
When mark visuals is fallen into current region 410, by this wait for mark figure be divided into boundary figure and
Figure outside boundary, and figure in boundary is determined as corresponding mark figure in current region 410.It has been observed that still with straight line
For section L4, straightway EF is the figure for falling into current region 410, i.e. EF is figure in boundary, then EF is set as working as by system
The mark figure of forefoot area 410.Similarly, system will be also set to the mark figure of current region 410 with GH.
Step S176 carries out mark according to 410 corresponding mark figure of current region to current region 410.
Specifically, as above-mentioned, system will carry out mark according to L3 and GH and EF to current region 410.
In this way, system automatically processes each spirte, mark accuracy is high.And during mark, the image of mark will not
Occur the incomplete Anastomosis Phenomena such as gap, overlapping, offset due to fractionation, while substantially reducing the working time, improves work
Make efficiency.
Fig. 5 is the flow diagram of the laser marking method of 3rd embodiment.In the present embodiment, pending figure at least
When part falls into current region, using the figure for falling into current region as the step of mark figure, i.e. also wrapped after step S175
It includes：
Step S175A judges whether pending figure is spirte that the last one waits for mark.
The last one when the spirte of mark in pending figure, select next spirte for waiting for mark as
Pending figure executes step S173.When pending figure is the last one spirte, execution is corresponded to according to current region
Mark figure mark is carried out to current region, that is, execute step S176.
Specifically, system works to current region, and it is current region that may have in the remaining spirte for waiting for mark multiple
Mark figure, it is also possible to all is not the mark figure of current region.Therefore will wait for the spirte of mark one by one with
Current region compares, until the spirte of needed mark all compares and finishes, with the mark figure of more complete acquisition current region,
So that mark is accurate.
In one embodiment, the coordinate of the endpoint of more pending figure and the boundary of current region judge pending figure
Further include after the step of whether at least partly falling into current region, i.e. step S174：
When mark figure does not all fall within current region, S175A is thened follow the steps, that is, whether judges pending figure
It is the spirte that the last one waits for mark.
In this way, the spirte of mark will be waited for one by one compared with current region by also ensuring that, until the subgraph of needed mark
Shape, which all compares, to be finished, with the more complete mark figure for obtaining current region so that mark is accurate.
Fig. 6 is the flow diagram of the laser marking method of fourth embodiment.According to the corresponding mark figure of current region
The step of carrying out mark to current region, i.e. step S176 include later：
Step S176A judges whether current region is the last one marking area, is the last one mark in current region
When region, terminate flow.When current region is not the last one marking area, next marking area for wanting mark is selected to make
For current region, that is, execute step S171.
Specifically, system handle simultaneously mark to all marking areas successively, so that all marking areas are all
Mark is completed, will finally wait for mark figure whole mark on workpiece.
Fig. 7 is the flow diagram of the laser marking method of the 5th embodiment.Fig. 8 is the schematic diagram of current region 810.Figure
9 be the schematic diagram of the second two-dimensional coordinate system.Mark is carried out to current region 810 according to 810 corresponding mark figure of current region
The step of, i.e. step S176 includes：
Step S176D establishes the second two-dimensional coordinate system in the region where mark range.
Specifically, it has been observed that the area and shape of the mark range of vibration mirror scanning type laser mark printing device and each marking area
Shape is all equal.When system is operated in current region 810, the region where mark range is current region 810.That is this implementation
In example, the second two-dimensional coordinate system (XO is established in current region 8102Y), the second two-dimensional coordinate system is as shown in figure 8, the second two dimension
Coordinate system is rectangular coordinate system.The origin of second two-dimensional coordinate system is O2, and origin is O2Positioned at the center of current region 810.
Coordinate of each point in the first two-dimensional coordinate system on mark figure is converted to and is sat in the second two dimension by step S176E
Coordinate in mark system.
Specifically, coordinate of each point (i.e. mark point) in the second two-dimensional coordinate system is mark coordinate on mark figure.It is false
If it is (x that a dozen punctuates on mark figure, which are coordinates of the I in the first two-dimensional coordinate system,3, y3)。x3, y3Value it is known that and
Origin O in two two-dimensional coordinate systems2Coordinate in the first two-dimensional coordinate system it is also known that, thus can obtain the first two-dimensional coordinate
The relationship of system and each point in the second two-dimensional coordinate system.Assuming that O2Coordinate in the first two-dimensional coordinate system is (x0, y0),O2
Coordinate in two two-dimensional coordinate systems is (0,0).Mark point I is converted into the mark point I ' in the second two-dimensional coordinate system, if I '
Coordinate is (x ', y '), then can be in the hope of
That is the coordinate of mark point I ' is the mark coordinate of vibration mirror scanning type laser mark printing device.
Step S176F, vibration mirror scanning type laser mark printing device is with the mark coordinate pair current region of each point on mark figure
810 carry out mark.
In this way, vibration mirror scanning type laser mark printing device carries out mark with the mark coordinate of transformed mark point, mark is accurate
