Description
Technical field
The present invention relates to a kind of laser black marking method of automatic assembly line, more particularly to the glass on automatic assembly line
The design of glass black laser marking method.
Background technology
Mark is wide variety of a kind of technology in production technology.Laser marking utilizes appropriate energy density, convergence
Target surface is scanned in the laser beam of workpiece surface, makes the change of material generation physically or chemically, forms trace on the surface
Mark, so as to form the process of mark.It belongs to a kind of non-contacting mark mode.Compared with traditional processing method, with should
With scope is wide, mark speed is fast, performance stable, quality is high, operating cost is low, environmental pollution is small, be easy to computerized control and
The advantages of run-in synchronism being realized with miscellaneous equipment.Therefore, laser marking turns into one of important applied field of laser.
Laser marking technology can be used for the marking of transparent material, in conventional transparent material mark, mainly there is three kinds at present
Method：1. CO is used2Laser carries out direct mark, but the contrast of this method sign is not high, is difficult in light material
Identification；2. direct mark is carried out using green laser, but green laser equipment cost is higher.3. ink-jet+infrared laser mark is used,
This method is larger to ink consumption amount, and ink consumables cost is also higher, and has certain pollution to environment, and this method marking
Mark is not corrosion-resistant intolerant to water.
Graphite carries on the back carving method and exemplar to be processed is placed on above graphite flake, makes its holding closely coupled, then by laser
Focus at interface, carry out marking.Research finds that the violent ablation due to laser to graphite flake is formed on a glass substrate
TRANSIENT HIGH TEMPERATURE high pressure effect at sedimentary, the sedimentary combination contact surface, absorption of the reinforcing glass substrate to laser energy is led
Causing laser spot, nearby glass temperature is constantly raised so that the shallow-layer of glass surface is removed, and then graphite particle is attached to
It is ablated go out shallow-layer in, realize the black mark of glass substrate, using graphite the back of the body carve by the way of, can be in transparent materials such as glass
Realize that quality is good on material, the high black mark of contrast, and the mark waterproof anti-corrosion of institute's marking；In addition, relatively conventional
Ink-jetting style, graphite can accomplish use repeatedly, therefore mark consumptive material is with low cost.
With the fast development of automatic technology, high-volume manufacture product mainly uses production line, the laser of glass
On-line marking is also to be carried out in production line.However, among mark process, exemplar needs accurate positioning, in addition, often
Secondary mark all needs to take some time, during this period face, it is desirable to which the position of galvanometer head and exemplar keeps being relatively fixed,
It ensure that the mark registration of laser marking and indeformable, otherwise can influence the quality of mark, cause mark bar code not
Can fast and accurately it be recognized.Because using graphite back of the body carving method, due to the high temperature action of laser beam, glass exemplar can
It is able to can attach on graphite flake, so as to influence the transport of glass exemplar；In addition, glass exemplar is after mark is completed, exemplar table
Face may adhere to graphite dust, be unfavorable for marking the identification of bar code.
The content of the invention
The laser black marking method of automatic assembly line a kind of is provided it is an object of the invention to consider above mentioned problem, should
Method efficiently continuously can carry out laser marking to the product on the conveyer belt of automatic assembly line.
The technical scheme is that：
The laser marking system and method for a kind of automatic assembly line of present invention design, feeding transmission one step-length of Tape movement,
Glass exemplar is put off on deflection positioner, and glass exemplar is positioned at suitable position by positioning side, now glass
Glass exemplar is in close contact with graphite flake, and laser beam is radiated at graphite flake with the interface of glass exemplar, carrying out by galvanometer head
The laser graphite back of the body carves mark, realizes the black mark of glass, after mark completion, and deflection positioner enters horizontal deflection, by
The glass exemplar for completing mark is moved on blanking conveyer belt, and dust understands that device will be attached to the graphite dust of sample surface and blow
Go, blanking conveyer belt transports the exemplar after completing mark and blowing；Feeding conveyer belt moves a step-length again afterwards, under progress
One wheel mark action.
The present invention using the graphite back of the body due to carving Mark technology, and graphite flake forms deposition by violent ablation on glass exemplar
TRANSIENT HIGH TEMPERATURE high pressure at layer, the sedimentary combination contact surface, so that absorption of the reinforcing glass exemplar to laser energy so that swash
Nearby glass temperature is constantly raised optical focus so that the shallow-layer of glass surface is removed, and then graphite particle is attached to and burnt
Lose in the shallow-layer, realize the black mark of glass exemplar.
The present invention is due to using positioning deflection positioner so that after the completion graphite back of the body carves laser marking, Neng Goushun
Glass exemplar is transferred to next station by profit, and is unlikely to high temperature action due to laser so that glass exemplar and graphite flake
It is bonded together, influences the normal operation of production line.
The present invention is due to the blanking transmission system that sponge is carried with transmission belt surface of use so that mark is completed
Glass exemplar when deflected positioner gets rid of and falls on blanking conveyer belt, easily will not break or slide collision into pieces,
This is due to the damping and anti-skidding effect of sponge.
The present invention is due to using clear chock dust remover so that due to the graphite powder for being graphite back of the body quarter and being produced at the exemplar back side
Dirt is enough easily to be removed, and is unlikely to be attached to sample surface, so as to improve the quality of exemplar mark, makes its discrimination more
It is high.
Advantages and positive effects of the present invention are：Using deflection positioner, the transport of exemplar is solved the problems, such as well；
Damping and antiskid function are provided using the blanking conveyer belt with sponge so that completed the glass exemplar of mark deflected fixed
Position device is got rid of when fall on blanking conveyer belt, is unlikely to break into pieces or is slided；And can then be solved using dust remove device
Certainly the graphite back of the body carves the dust problem produced, so as to improve the quality and discrimination of mark bar code.This laser automatic assembly line
The good effect that glass black marking method is brought is：Be conducive to developing laser marking technology in glass even transparent material
On realize the application of black mark, realize the design of increasingly automated black marking production line；In addition, graphite back of the body carving method is marked
The mark corrosion-resistant and high-temperature resistant at quarter is water-fast, and this method mark consumables cost is low, and mark quality is good.The present invention realizes glass
Black mark automatic production line design, be a kind of ingenious in design, function admirable, convenient and practical, processing cost is low to swash
The glass black marking system of light automatic assembly line.
