After a lot of people bought laser engraving machine, only know the work, do not know how to maintain, how to introduce the following laser engraving machine maintenance, extend the service life.

    1, engraving machine fan cleaning

    The use of the fan for a long time, will make the fan inside the accumulation of a lot of solid dust, so that the fan produce a lot of noise is not conducive to exhaust and taste.When the fan suction is not enough to exhaust the smoke not free, first turn off the power, the fan on the inlet and outlet of the air pipe off, remove the dust inside, and then the fan upside down, and pull the inside of the wind blade straight until clean, and then the fan installed.

    2. Water replacement and water tank cleaning (it is recommended to clean the tank and replace the circulating water once a week)

    Clean the water tank: first, turn off the power, unplug the water inlet pipe, let the water in the laser tube flow into the tank automatically, open the tank, take out the water pump, and remove the dirt on the pump.Clean the water tank, replace the circulating water, restore the water pump to the water tank, insert the water pipe connecting the water pump into the water inlet, and arrange the joints.Power the water pump separately and run for 2-3 minutes (make the laser tube full of circulating water)

    Note: The laser tube must be filled with circulating water before the machine works.

    The water quality and temperature of circulating water directly affect the service life of the laser tube. It is recommended to use pure water and control the water temperature below 35℃.If the water exceeds 35, replace the circulating water or add ice cubes to the water to reduce the temperature.(It is recommended that users choose a cooler or use two water tanks)

    3. Cleaning of the lenses (it is recommended to clean the lenses before work every day, and the equipment should be turned off)

    Machine is introduced in front has talked about in the engraving 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.Lens is easy to be stained with dust or other pollutants, resulting in laser loss or lens damage, No. 1 and No. 2 lenses should not be removed when cleaning, just dip in the cleaning solution of the mirror paper along the center of the lens to the edge of rotation wipe carefully.The no. 3 lens and the focusing lens need to be taken out of the frame and wiped in the same way. After wiping, the lens can be put back as is.

    Note:

     (1) The lens should be gently wiped, do not damage the surface coating

     (2) Wipe the process should be handled gently, to prevent falling;

    Please keep the concave face downward when installing the focusing mirror.

    4. Optical path inspection

    Light path system of laser engraving machine 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.

    5. Fastening of screws and coupling

    Movement system in the work of a period of time, the movement of the screw, coupling will become loose, will affect the stability of mechanical movement, so in the machine operation to observe the transmission parts have abnormal sound or abnormal phenomenon, find the problem should be timely firm and maintenance.At the same time the machine should be hardened one by one with tools over time.

 

---

    The following is the laser engraving machine laser tube is not bright this problem, we start with a few common solutions, together to solve the analysis of specific reasons.

    (1) A voltmeter with an indication is usually found when the power supply line is open.Bad contact with foot switch or manual switch.Check: Measure with a multimeter.To repair or replace.

    (2) The voltmeter has no indication of common fuses, or the circuit has open circuit inspection is measured with a multimeter.Handling: Replace the fuse, or close the circuit.

    (3) When the power indicator light is not on, the common fuse is broken, the incoming line contact is bad, the indicator line is bad or the indicator light is broken.Check: Check the fuse, check the power inlet line, and check the indicator light loop.Treatment: replace fuse, repair lead and replace indicator light.

    (4) Continuous fuse is commonly seen in short circuit in the machine, and serious dirt in the machine.Check: check the line step by step, there is short circuit in the high voltage part.Treatment: repair short circuit and remove dirt.

    (5) There is discharge sound or arc light in the machine. Dust, water or air humidity are too high and corrosive gases are commonly found in the machine.Inspection: Observe the discharge point in the dark.Treatment: remove dust, water and other things, change the working environment.

    (6) Laser engraving machine laser output instability in the machine in bad contact, the machine has a slight intermittent short circuit point.Check: Check the line step by step.Treatment: replace the wires, reweld the ends, and clean them.
