3 Product Introduction
3.1 Overview
Laser cleaning is non-grinding, non-contact, non-thermal effect, and suitable for
cleaning objects of various materials. Laser cleaning is considered to be the most
reliable and effective cleaning method. At the same time, laser cleaning can solve
problems that cannot be solved by traditional cleaning methods. The traditional
cleaning industry uses a variety of cleaning methods, and most of them are chemical
and mechanical methods. As environmental protection regulations become more and
more strict and people’s awareness of health and environmental protection is growing,
the types of chemicals that are permitted to be used in industrial production cleaning
will become less and less. Producers have to find a cleaner and environmentally
friendly cleaning method.
Laser cleaning equipment is a new generation, high-tech product for surface cleaning.
It is easy to install and simple to operate, and can also be automated. It can conduct
cleaning without chemical reagents, without medium, without water. Laser cleaning
equipment has the following advantages. Its focus can be manually adjusted. It can
conduct fitting surface cleaning. The surface cleaned by it has higher cleanliness.
Laser cleaning equipment can be used to remove resin, oil, stains, dirt, rust, corrosion,
coatings, paints, etc. on the surface of objects.

cleaning head are free of dust and dirt.
3. Check and make sure that all buttons and switches on the machine are in a
normal state.
4.2 Steps for Installation
Setp 1.
Open the package. Check and make sure that the machine is free of
damage. Check and make sure that all parts are complete and free of
damage.
Setp 2.
Take out the external power cord, connect the aviation plug to the cleaning
machine, and connect the white plug to the power outlet. The power
indicator lights up in white after the machined is powered on.
4.3 Steps for Usage
Setp 1.
Operation buttons and indication information as shown in Figure 5
1) The “Emergency” button should be set to the unscrewed position.

button, the control system is powered on and the indicator of the
“START” button lights up. After 12 seconds, the laser source is
powered on and enters the running state.
3) Add water into the chiller to the required level, power on the chiller,
then check and make sure that the cooling water circulates normally.
4) For the laser source, power on the circuit breaker on its rear panel, then
turn the key switch on its front panel to “ON”. Wait for 12 seconds,
press the “LASER” button, the indicator light up, indicating the laser
source runs normally.

5 Product Design and Structure
The laser cleaning machine consists of an optical system, a mechanical system, and an
electrical control system. The following is the design of each subsystem.
5.1 The Electrical Control System
As shown in Figure 6, the electrical control system consists of the laser source, the
core control board, the digital-to-analog converter board, the driver board, the
galvanometer, and the 7-inch touch screen. First, the core control board controls the
emission and shutdown of the laser through the DB25 interface, and the laser
frequency and the laser power can be set through the touch screen. Then, through the
galvanometer control interface the core control board controls the digital-to-analog
converter board to generate analog control signals to control the driver board, which
will drive the galvanometer to generate a cleaning track for cleaning. The scanning
speed, length, and width of the pattern can be set on the 7-inch touch screen, which is
controlled by the ARM main control board.

5.2 The Optical System
As Figure 7 The Working Diagram of the Optical System shows, the galvanometer is
driven by the galvanometer motor to complete the ±7.5° scanning. The collimated
beam emitted by the laser source first passes through the mirrors and enters the
galvanometer to complete the X-direction scanning. Then, the outgoing scanning
beam enters the field lens and is focused on the working surface to complete the
scanning trajectory.

check whether the lens of the cleaning head is contaminated. If it is
contaminated, please first wipe it with a cotton swab dipped with alcohol.

After use, check again whether the field lens is contaminated. If it is
contaminated, please wipe it with a cotton swab dipped with alcohol. Then
cover the field lens with the protective cover and put the hand piece on its
holder, which is on the right side of the equipment. Finally, place the SF300CP
Laser Cleaning Machine in a flat, vibration-free, shock-free environment for
the next use.
