chapter4. System Maintenance

The stable and normal working of the machine depends on the correct operation and
routine maintenance. This chapter describes the daily maintenance of the equipment.

4.1 Mechanical Maintenance

The mechanical design of this machine is designed in the concept of 10 years
maintenance-free.

If mechanical failure is caused by unpredictable external factors, please contact the
manufacturer.

4.2 Electrical Maintenance

The electrical maintenance mainly includes electrical components, buttons, marking control
card, and sensors.

 Regularly check if the power indicator of the electrical box switch is normal, if the

wiring is loose, if the cable is aging, if the output voltage meets the specifications,
check the heat dissipation, if there is contamination or blockage, and resolve in
sequence.

 Regularly check the contact sticking of the intermediate relay, if the wiring is loose and

if the indicator is normal.

 Regularly check the air volume of the cooling fan is normal, if the speed is normal, if

there is abnormal sound, if there is contamination or blockage, and resolve in
sequence.

 Regularly check if the marking control card LED is normal, if the chip cooling is in

reasonable limit, if the connector is loose, if PCB is contaminated and resolve in
sequence.

 Regularly check if the sensor fiber optic cable has any mechanical or corrosion damage,

if the indicator is correct, if fiber head is contaminated and resolve in sequence.

 Regularly check the computer and monitor hardware maintenance and system

maintenance to ensure the normal operation of the software.

4.3 Maintenance of Optical Path and Optical Devices

The optical system of the fiber laser marking machine consists of fiber laser, optical
scanning galvanometer and optical scanning field lens.

It is inevitable for the optical element to contact with the suspensions when the laser is
operating. When the laser is cutting, engraving or marking the material, the build surface will

30

release a lot of gas and splashes, which will damage the lens. When the contaminant falls on the
lens surface, it will absorb energy from the laser beam, resulting in thermal lens effect. If the lens

hasn’t formed thermal stress, the operator can disassemble and clean it. The method should

avoid damage to the lens and further contamination.

 General Operation Principles

In the installation and cleaning process of lens, any sticky material, even nail print or oil
droplets, will increase the absorption rate of the lens and reduce service life.

Therefore, the following precautions are required:

 Do not use suction device or inflatable equipment to avoid scratching the lens

surface;

 Hold the edge of the lens rather than the film when take lens;
 The lens should be stored in a dry and clean place for testing and cleaning. A good

console should have several layers of cleaning tissue or lens tissue on the surface;

 The operator should avoid talking over the lens, and keep food, beverages and

other potential contaminants away from the working environment.

 The correct cleaning method

In the process of cleaning the lens, the only purpose is to remove the contaminants, and
avoid further contamination and damage. To achieve this goal, people tend to use an approach
with relatively small risk. The following procedure is established for this purpose.

First, first blow the floating material off the lens surface with air ball, particularly the fine
particles and wadding material on the lens surface. But do not use compressed air on the
production line, because the air will contain oil and water droplets, which will deepen the lens
contamination.

Secondly, clean the lens with acetone or anhydrous alcohol (reduce the possibility of lens
contamination)

Dip the lens paper in acetone and clean the lens in the light, and move circularly. Once the
lens paper is dirty, it must be replaced. The cleaning must be finished in one time to avoid
scratching.

Some contaminants and lens damage can’t be removed by washing, for example, film burn

due to dirt, stripping caused by condensation. In order to restore perfect performance, the only
way is to replace the lens.
