Description
Technical field
The present invention relates to a kind of laser means for removing body of a motor car paint, it is that one kind utilizes nanosecond laser straight-writing system
The method for removing body paint is processed to the region for needing paint-removing, this method can be maintained applied to car detailing,
The reparation of automobile green high-efficient and remanufacture field.
Background technology
Laser processes processing method as brand-new material, is play the role of an innovation point, it is represented
The developing direction of advanced manufacturing industry, greatly improves the technical merit of traditional manufacture, brings product design, manufacturing process
With the dramatic change of production idea.The laser new technology that laser Removal Technology grows up as last decade, increasing
Industry is played and more importantly acted on.Laser cleaning is a kind of using high energy laser beam irradiation workpiece surface, makes surface
Dirt, rust staining or coating occur flash evapn or stripping, while not changing or damaging substrate material property, so as to reach surface
Purifying technical process.
Re-manufacturing technology can repair waste product, it is ensured that product quality, life-span and performance reach the standard of new product.Cleaning
Technology occupies critical role as the premise of re-manufacturing technology during whole remanufacture, and cleaning parts quality will be direct
Influence remanufactures the quality of product.Conventional clean technology such as chemistry is removed, mechanical grinding, because easily causing stress corrosion cracking
Line, introduce new pollutant, remove the problems such as low uneven and efficiency, operation and aggravation environmental pollution whard to control.And laser
Cleaning is a kind of " green " cleaning method, with without using any chemical agent and cleaning fluid, secondary pollution, nothing are not produced
Grinding and untouchable process, various types of pollutants of various material surfaces can be removed, reach that conventional cleaning can not reach
To cleannes, wash efficiency high, the advantages of saving the time.The technical advantage of laser solves conventional art development presence well
The problem of, it also imply that laser technology will replace the trend of conventional art.
In China, automobile has become instrument indispensable in people's life, and the thing followed is exactly automobile quantity one
Rise on road.According to Ministry of Public Security's traffic administration office data, China's car ownership has reached 1.37 hundred million, private car within 2013
Possess total amount and also break hundred million first, automobile total quantity reaches 5.7 times of automobile quantity in 2003.The auto industry developed rapidly certainly will
To bringing huge development potentiality and space from sale of automobile to automobile maintenance.Automobile daily and regularly safeguarding protects
Support, it is main include cleaning, repair, check, adjustment, fastening, in terms of lubrication.Because body of a motor car paint is exposed outside, easy quilt
Breakage is scraped, this causes the reparation of body of a motor car paint maintenance to turn into a big important component of car detailing.
It is as follows that current widely used body of a motor car paint repairs flow：Sand paper polishing → pothole is filled up → dries → again
Polishing → pothole is filled up → air-dries → other position protection → spray paintings.Whole process has following defect：(1) technique is cumbersome,
Waste time and energy；(2) manual polishing can not ensure bodywork surface uniform force, cause polishing effect not to be guaranteed；(3) polish
During need cleaning, cause water resource waste；(4) cost of labor is continuously increased.A variety of negative factors above are caused currently
There is the defect being difficult to avoid that in paint repair process, therefore laser Removal Technology turns into a kind of rationally effective alternative means.

Strafe at a predetermined velocity, obtain the fresh section gone after paint-removing.
Step 4：Easy clean, obtains surface by the finished work-piece to be painted of texturing.Surface dust is specially absorbed, is obtained
To surface by the finished work-piece to be painted of texturing.
Wherein, the cleaning fluid of chemical solution cleans described in step 2 is alkyl and fatty alcohol ether compound is main component
Solution be watered after the surface activity liquid prepared.
Wherein, described in step 3 in laser processing procedure, LASER Light Source can be spot light or line source；Setting swashs
Light device parameter is as follows：Power P=10~100W, pulse width τ=0~30ns, frequency f=0~100kHz, wavelength X=532~
1064nm, I=30~100A, υ=0~2000mm/s, number of repetition n=10 times.
Wherein, it is small-power induced-draught fan that surface dust device therefor is absorbed described in step 4.
The advantage of the invention is that：
(1) this method cleans surface damage painting workpieces using high energy bundle of pulsed laser, and no fuel factor is to matrix not damaged；
(2) this method utilizes high energy beam laser cleaning surface damage painting workpieces, can effectively improve body of a motor car table
The removal effect of face paint, obtains cleaning section；
(3) this method can reach general applicability to different colours car paint by adjusting laser parameter；
(4) surface is cleaned using water this method avoid a large amount of, it is to avoid water resource waste, at waste water
The problem of reason, recycling；
