Specific embodiment
In order to more clearly state the present invention, the present invention is further described with reference to the accompanying drawing.
Please refer to Fig. 1 and Fig. 3, a kind of netted laser cleaning system of the invention, comprising: light source unit 1, the first reflecting mirror
2, the second scintilloscope 4, the first driving unit 3, the second driving unit 5 and focus lamp 6, light source unit 1 pass through after generating laser beam
First reflecting mirror 2 and the second reflecting mirror 4, then be focused by focus lamp 6, so that laser beam 7 acts on metal cleaning surface, the
One driving unit 3 and the second driving unit 5 drive the first reflecting mirror 2 and the second reflecting mirror 4 to be moved, so that laser beam 7 exists
In certain range, is moved according to specific netted cleaning track, realize the cleaning to metal surface.In the present embodiment, make
It is worked with the first driving unit of motor driven and the second driving unit, the first reflecting mirror and the second reflecting mirror are back and forth transported
Dynamic, the amplitude of fluctuation of the first reflecting mirror is a, and the motion amplitude of the second reflecting mirror is b, and the amplitude of fluctuation of the first reflecting mirror is big
In the second reflecting mirror, two reflective mirrors all use amplitude of fluctuation to be moved, so that motion profile is camber line；Simultaneously because
The motion amplitude of two reflective mirrors is inconsistent, and the amplitude of fluctuation of the first reflective mirror is smaller, and the period of motion of two reflective mirrors is not
With, therefore the displacement in the identical time is entirely different.
In practice, light source uses pulse laser, and the repetition rate of pulse laser is 200-300KHz, wavelength
Range is in 160-1200nm；The system is applied to Handheld laser cleaning or fixed laser cleaning.
Please refer to Fig. 4 and Fig. 5, the invention also discloses a kind of netted laser cleaning method, laser cleaning method include with
Lower step:
S1: from the off, the first driving unit drives the first reflecting mirror to move according to amplitude of fluctuation a, and the second driving unit drives
Dynamic second reflecting mirror carries out pendulum motion according to amplitude b, then the laser beam after focusing is in clean the surface forming curves track；
S2, when the first reflecting mirror move distance reaches setting value, the first driving unit drive the first reflecting mirror opposite direction movement；
Second driving unit drives the second scintilloscope to carry out pendulum motion according to amplitude b, and the laser beam after focusing is formed in clean the surface
Backhaul curvilinear path；
S3, when the first reflecting mirror completes 360 degree of a cycle of movement, phase locating for the second reflecting mirror is Y1 at this time;
S4, the starting point moved using the point as second, repeat the movement of S1 and S2；When the first reflecting mirror completes a cycle
When 360 degree of movement, phase locating for the second reflecting mirror is Y1+Y1 at this time；
S5, so circulation complete a drawing period, the phase of X and Y when Y1, which multiplies n times, is equal to 360 degree of integral multiple this moment
It is consistent with phase when starting starting point；Obtain the netted scanning patter track of a closure.
In this step, only when the equal round numbers of Y1*N-360*M=0(M and N) when, entire scanning motion completes one completely
Period, N is bigger, and the grid of netted track the close small, and in step sl, first reflecting mirror and the second reflecting mirror carry out
It moves back and forth, the amplitude of fluctuation of the first reflecting mirror is a, and the motion amplitude of the second reflecting mirror is b, the swing of the first reflecting mirror
Amplitude is less than the second reflecting mirror.In a particular embodiment, the swing speed of the first reflecting mirror is 1500 chronomeres, and second is anti-
The swing speed for penetrating mirror is 1000 chronomeres, and after the first reflecting mirror from left to right moves to setting value, track movement is
A, carries out counter motion at this time, track b, when the first reflecting mirror returns to initial motion point, the movement of the second reflecting mirror at this time
Anchor point for 1500-1000=500,500/1000*360 degree=180 degree, i.e., laser at this time is located under initial motion point
Side, angle is 180 degree；When using primary movement, track is respectively c and d, and angle is 180+180=360 degree, and is just
It in the period of first reflecting mirror movement, is overlapped at this time with the period of motion of the first reflecting mirror, to return to origin；Formation one is complete
The whole period of motion, it is netted track which, which is formed by track,.If applying when on fixed laser device, may be used also
With on the second reflecting mirror be arranged a tiny variable, realize automatic position-changing so as to not moving substrate, to substrate surface into
Row cleaning.
Present invention has an advantage that
1) due to reducing in a short time in a pocket Repeat-heating, so that maximum temperature reduces, so that substrate be made to damage
It reduces；
2) laser point plays the increasing of temperature rise caused by when on object to be cleaned, so that explosive forces caused by particulate matter expands are more
By force, so that cleaning effect is more preferable；
3) any direction has multi-point scanning, so that cleaning is more evenly changed, so that cleaning materials is more smooth.
Disclosed above is only several specific embodiments of the invention, but the present invention is not limited to this, any ability
What the technical staff in domain can think variation should all fall into protection scope of the present invention.
