Abstract
The invention belongs to laser processing technologys, are related to the method for laser scoring Quick Response Code；The present invention scribes Quick Response Code in product shell outer surface using laser beam, improve product quality stability and production efficiency, realize production of intelligent (computer programming may be implemented in etching laser machining), it reduces and operates labor intensity, the permanent and reliable recognition that realizes product identification, the information system management requirement and product quality for meeting military use product trace requirement.
Description
Technical field
The invention belongs to laser processing technologys, are had reached for scribing Quick Response Code with laser beam on product shell outer surface
Two-dimensional code scanning rifle can be used quickly to identify the purpose of the product information assigned on Quick Response Code.
Background technology
Requirement can be traced according to military use product information system management and product quality, is needed in housing outer surface mark for oxygen product
Know product relevant information include product type, name of product, production unit, production batch, the date of production, mating user and
The bulk informations such as technical target of the product, so a large amount of information can only be integrated in Quick Response Code and could realize.And in product shell
On outer surface identify Quick Response Code mode it is currently used there are three types of：First, Quick Response Code mark is pasted in surface of shell, but it is this
Over time, the Quick Response Code mark for easily causing stickup falls off mode；Second is that in product shell outer surface riveting Quick Response Code metal inscription
Board, but shell effective thickness can be caused to be reduced because of embedded rivet in this way and then casing rigidity is caused to decline；Third, in product shell
The shortcomings that external surface scribes Quick Response Code using laser beam, and this mode has evaded first two mode, but there are the following problems：
1. before surface of shell processing, Quick Response Code is scribed with laser beam, the interference due to plating after surface treated occurs
It causes to be difficult to even be identified with scanner.
2. after surface of shell processing, with laser scoring Quick Response Code, there is shell two after environmental test (salt spray test)
Code region corrosion is tieed up, Quick Response Code clarity is caused to decline, is equally difficult to even None- identified.
Invention content
The purpose of the present invention is：Realize that the reliable recognition-of Quick Response Code can accomplish influence because coating layer interferes
Identification ensures that two-dimension code area will not influence to identify because corrosion occurs for environmental activity again.
The technical scheme is that：The method of laser scoring Quick Response Code, which is characterized in that before surface treatment, in shell
External surface scribes Quick Response Code with laser beam, to ensure that two-dimension code area acquisition protective layer will not be made because of environment after surface treated
With and corrosion occurs；Quick Response Code is identified with infrared scanning rifle, and optimizing laser beam according to recognition effect scribes Quick Response Code technique ginseng
Number scribes Quick Response Code, then surface treated, blackness and coating layer blackness using the laser beam after optimization Quick Response Code technological parameter
It remains to keep apparent " aberration ", to ensure that Quick Response Code can be identified quickly with scanner.
Surface clean is carried out to the part of processing before housing outer surface scribes Quick Response Code with laser beam.
The technological parameter of the laser beam includes velocity of displacement, laser beam frequency, laser power coefficient and scribes number,
Different coating need to match different technological parameters.
Different coating need to match different technological parameters：
It is an advantage of the invention that：Quick Response Code is scribed using laser beam in product shell outer surface, it is steady to improve product quality
Qualitative and production efficiency realizes production of intelligent (computer programming may be implemented in etching laser machining), reduces and operate labor
Fatigue resistance realizes the permanent and reliable recognition of product identification, meets information system management requirement and the product of military use product
Quality traces requirement.
Specific implementation mode
The method of laser scoring Quick Response Code, which is characterized in that before surface treatment, scribed with laser beam in housing outer surface
Quick Response Code, to ensure that because of environmental activity corrosion will not occur for two-dimension code area acquisition protective layer after surface treated；With infrared
Line scanner identifies Quick Response Code, and optimizing laser beam according to recognition effect scribes Quick Response Code technological parameter, the technique of the laser beam
Parameter includes velocity of displacement, laser beam frequency, laser power coefficient and scribes number, after optimization Quick Response Code technological parameter
Laser beam scribe Quick Response Code, then surface treated, blackness remains to keep apparent " aberration " with coating layer blackness, to protect
Card Quick Response Code can be identified quickly with scanner.
Technical process is as follows：
1, surface clean：Machined part, surface attachment cutting oil or cutting fluid, if do not cleaned up, meeting exists
When laser scoring Quick Response Code, because localized hyperthermia causes to be sintered, forms nonmetal oxide and cover two-dimension code area, influence Quick Response Code
Pattern definition, it is difficult to identify；On the other hand, this nonmetal oxide is when sequent surface is handled, it is also difficult to remove, influence
Therefore coating quality should will wait for laser scoring two dimension before laser scoring Quick Response Code using safety and environmental protection leaning solvent
The piece surface dirt of code cleans up.
2, laser ablation Quick Response Code：Laser beam, which is carried out, by technological parameter as defined in table 1 scribes Quick Response Code.
Table 1
3, removing surface (on-demand)：For copper and copper alloy, stainless steel parts, after laser scoring Quick Response Code, in two dimension
Code region can form more black metal oxide, and pattern in 2 D code is made to thicken.To ensure recognition effect, should use dry
Net wiping cloth (rags) wipes excess surface oxide away, until Quick Response Code shows clear pattern.
4, it examines：Quick Response Code is identified with infrared scanning rifle.Meanwhile visual inspection is scribed region and should be used without slag, Rong Dong is melted
Multiple is that 3~5 times of lens examination scribes region and answers flawless.
5, it is surface-treated：The technological requirement listed by table 2 carries out the shell after laser beam scribes Quick Response Code at surface
Reason.
Table 2
6, it examines：After surface treatment, should use infrared scanning rifle to the Quick Response Code on the part after surface treatment again
It is identified.
7, it is put in storage：Qualified parts handle storage.
For there is the structural member of intensity requirement, laser beam should be limited the use of and scribe Quick Response Code method, because laser beam is scribing table
Heat affected area may be will produce on face, material structure and performance is made to change；Unless being able to verify that this method does not reduce structure
The security reliability that part uses.
