Fault detection of optical fiber laser marking machine _ how to maintain repair

Release time:2017年08月22日    Keyword:    Release people:佚名

Laser marking machine maintenance is refers to the laser marking machine malfunction cannot work normally when looking for a professional personnel for maintenance and repair work, including many maintenance project, this article explained important optical fiber laser marking machine fan, light path, lenses and screw, coupling detection and maintenance.


The lens is clean


Marking machine has three pieces of reflector and 1 piece of focusing mirror (1 reflector in the laser tube, the launch of the exit is at the upper left of the machine, the reflector is in the left side of the beam's # 2 and # 3 mirrors in laser head on top of the fixed part, is located in the lower part of the laser focusing mirror adjustable lens barrel), after focusing laser is through the lens reflex, emitted from a laser. Lenses can easily touch dirt or other contaminants, cause loss or damage of lens of laser, no. 1 and no. 2 don't must be removed, while the lens cleaning need to dip in a cleaning fluid to clean lens paper carefully wipe up along one edge of the lens central to rotary. No. 3 lens and focus mirror need to be removed from the frame, wipe it in the same way, and put it back as the original.


The fastening of screws and coupler




Motion system of laser marking machine at work after a period of time, movement joint creates a loose screw, coupling, will influence the mechanical movement smoothness, so in the running of the machine should observe the driving part is there any sound or abnormal phenomenon, found that the problem has to be strong in a timely manner and maintain. Meanwhile, the machine should spend some time using tools to firmly screw the screws. The first solid should be about a month after the device is used.


Fan cleaning


The use of the fan for a long time, can accumulate a lot of solid dust in the fan, let the fan produce a lot of noise, also be adverse to the exhaust and deodorous. When appear insufficient suction fan smoke not free, turn off the power supply first, will be discharged into the duct and the duct on the fan, remove the inside of the dust, and then put the fan on, and pull out the inside of the blades, until clean, then put the fan installed.


Inspection of the light path


Optical fiber laser marking machine light path system is made up of mirror reflection, together with the focus lens focusing focus lens in the optical path was not found deviation problem, but the three mirrors is composed of mechanical part is fixed, the possibility of deviation is bigger, although usually does not happen, but suggest user before each work be sure to check the light path is normal.
