Laser marking machine leakage 1, how to deal with the leakage problems leakage phenomenon many machines, the leakage phenomenon is to touch the machine will have the feeling of acupuncture as metal parts.
A slight tingling leakage voltage under 100 v, when strong tingling leakage voltage will probably be around 150 v.
2, the causes of the leakage (1) some electrical appliances used in circuit board itself has a problem, the electrical appliances are a kind of switch power supply.
The electricity is not much danger to people, because the circuit board and have a great resistance value between mains, the current is very small.
(2) some components or leakage especially capacitance due to the circuit board be affected with damp be affected with damp, dust is too much, also can appear the phenomenon of leakage, such as some electrical appliances shell is not charged at the beginning, but then was charged after a period of time, more belong to this kind of situation.
3 the leakage, leakage detection method is electrical after somehow connected between the enclosure and wire electric has certain potential difference between a and to produce.
Methods to detect the leakage is electricity pen charged body contact, if neon bulb light goes out immediately, have proven to be charged with static electricity, if light is leakage.
4, the leakage solution (1) the simplest approach is to exchange the position.
(2) cleaning the dust in the circuit board, especially the dust in the power supply board.
(3) if the above methods are not, then the most effective way is to ground.
How to do laser marking machine can avoid the phenomenon of sparks avoid the phenomenon of sparks pay attention to the following: 1, increase of the laser marking machine, laser frequency.
2, optimization of laser speckle pattern.
3, change the marking mirror at the airport and the distance of the workpiece, which is to do some coke.
4, increased in the process of processing auxiliary gases.
Such as the CO2 laser marking machine in the process of wood processing, can increase the cheap nitrogen, can make the wood after marking not black.
5, using femtosecond laser, namely the high frequency laser can achieve similar to the effect of cold working.
6, use ultrashort wave length of laser, such as ultraviolet laser marking machine, also can achieve similar to the effect of cold work, laser energy directly to destroy processing material atoms.
