Technical field
It flies Mark technology field the invention belongs to laser, and in particular to a kind of online flight laser mark printing device and its control
Method processed.
Background technique
As industrial level is continuously improved, requirement of the factory to production efficiency is also stepped up, and many factories use flowing water
Line production, for save the cost, many manufacturers transport different products using same assembly line, and the product on assembly line is not
Meanwhile the speed of assembly line is not also identical.Mark is flown in use, when flowing water linear velocity changes in tradition, is needed artificial
Adjust sensor position, with guarantee by information marking all products same position.
And for a mark assembly line, in the case that the position of optical bench and sensor has all been fixed, if belt
Transmission speed changes, then the position of marking can also change on product, or even can not the mark on object.At present
In daily production, the product of many times belt transmission is different, needs to adjust belt transport speed, in order to guarantee marking machine
Carved in the enterprising rower of the same position of product, then need to adjust the position of sensor, this is because in the production line, optical bench and
The position of sensor be it is fixed, sensor installation position and optical bench on galvanometer between there are certain distance s1, work as production
Linear velocity is v1When, sensor senses object and mark signal is sent to laser progress mark, and this period is laser
The delay time t of mark1, i.e.,：, and object is also required to from the position that sensor senses object to galvanometer mark location
Certain time, i.e. delivery time t2, only delay time t1With delivery time t2When equal, laser just understands each marking in object
The same position of body, once and producing line speed changes, the delivery time shortens or elongated accordingly, i.e. the delivery time is less than
Or it is greater than delay time, lead to every time that the position of mark is different on object；Ordinary circumstance is all to change sensor again
Installation site keeps two times equal, can just continue mark.However, being needed if change belt transport speed is more frequent
