How To Use The Laser Cleaning Machine

1 . Overview

This manual covers the general description of the basic installation, factory setting, operation and maintenance services of SUP series 22C handheld cleaning head products.

SUP22C Laser hand held cleaning head is a newly launched application in the field of hand held cleaning single motor scanning swing laser head——hereinafter referred to as SUP22C. The product covers the handheld laser cleaning head and the self-developed control system, and sets multiple safety alarms and active safety power failure, blackout Settings. It is developed on the basis of our mass production of SUP21Chandheld laser cleaning head. Compared with the previous generation, it is further improved in insulation, stability, maintenance and other aspects, and has more

compact, lighter and more reliable characteristics.

The product can be adapted to various brands of fiber laser, can work stably for along time under3000W, optimize the control program, so that the overall cleaning effect is more uniform.

● The whole machine is more stable: all parameters can be seen, and the state of the whole machine is monitored in real time to avoid problems in   advance, facilitate troubleshooting and trouble shooting, and ensure the  stable operation of the hand-held cleaning head.

● Unique air knife design: the unique exit "air knife" design, can greatly increase the light port protection gas flow rate, better prevent lens pollution.

● Controlled parameters and high repeatability. Stabilize the mechanical structure and lens state, only to meet the laser power stability, the process parameters must be repeated, greatly improve the efficiency.

As shown in Table 1.1, the operating environment requirements and main parameters of SUP22C:

Table 1.1 Operating environment requirements and main parameters of SUP22C

1.2 Pay attention to information

(1)Ensure reliable grounding before power supply.

(2)The laser output head is connected with the hand-held laser head

through QBH, please carefully check the laser output head to prevent dust or other pollution. Please use special lens paper when cleaning the laser output head.

(3)If the equipment is not used according to the method specified in the manual, it maybe in an abnormal working state and lead to damage.

(4)When replacing the protective mirror, please ensure good protection.

(5)Please note: for the first time, when the red light cannot come out of the copper mouth, be sure not to shine.

2. Installation and connection

2.1 Controller interface definition

Hand-held laserhead controllerinterface definition as shown in Table 2.1:

Table 2.1 Definition of the SUP22Ccontrollerinterface

2.1.1 Power supply terminal of the controller

The power supply end uses 5Pinterface, with random 24V switching power supply and ±15Vswitching power supply.

Please note that the 15Vswitchingpower supply distinguishes between positive and negative poles, V1 +15V, V2-15V, any COM on the 15Vswitchingpower supply is connected to the 2pinGND!

Please note that the switching power supply must be grounded!

2.1.2 The LCD screen terminal of the controller

The LCD screen wiring is randomly attached and connected directly.

See Table 2.1 above for specific definition.

2.3 optical fiber input interface

SUP cleaning head is suitable for the vast majority of industrial laser generators, commonly used optical fiber joints including IPG, Ruike, Chuangxin, Feibo, Spurs, Jept, Kaplin, etc. The optics must be kept clean, all dust must be removed before use, and the torch head must be placed horizontally to prevent dust from falling into the interface.

method of erection

2.4 protect the gas and the water cooler interface

The waterpipe and gas pipe interface can be installed with a hose with outer diameter 6mm inner diameter 4mm. Access and exit pipeline of waterway.(regardless of entry and exit direction)

The cooling system distinguishes the water part of shampoo and the water part of optical fiber head in series, as shown in the figure below:

Fig. 2.2 Schematic diagram of cleaning head and optical fiber head waterway

2.5 The connection interface between the cleaning gun and the control box

The hand held cleaning head is connected to the control box through a group   of "multi-function system connecting cables". The hand held cleaning head is the aviation plug female head, and the control box end is the aviation plug

male head. The six-core wire gun body controls the light and temperature monitoring, and the two-core and five-core wires are the vibrator motor control line.

whether the control box detection and the oretical value function is normal.

4. Maintenance

Maintenance and replacement method of related lenses:

① Before operation, please clean your hands and dry them first, and then wipe your hands with cotton and alcohol again.

② Open the protective mirror in a relatively dust-free place, focus the mirror compartment cover, pullout the lens bracket, do a good job of protection (beautiful paper cover), check the protective lens, if there is an obvious burning point on the lens surface, should be directly replaced.

③ Then check the white storage seal ring under the lens. (If the storage sealing ring cannot be used, it must be replaced immediately.

④ Wipe the warehouse mouth and the inside of the warehouse cover with a cotton ball dipped in alcohol, quickly insert the protective lens bracket into the protective mirror compartment, and lock the screws.

5. common exception handing

5.1 warning of laser/water cooler lair press real arm

① If the above alarm does not using the alarm signal, please change the alarm level of screen setting page.

② If the alarm appears in the above alarm signal, check whether the alarm or the high and low level of the alarm signal is set correctly.

5.2 screen not bright/click not responsive

① The screen is not bright, make sure the controller is powered on. Check whether the controller and the four-core wire of the screen are connected correctly, and whether the voltage of foot1 and 4th foot 24Vis normal.

② If not clicked in normal use, check whether the temperature of the machine is too high.

③ Click unable to input, check whether the wiring between the controller and the screen is correct, and whether the second and third feet are normal.

See 2.1.2 controller display end for details.

④ Newly installed equipment click no reaction maybe the system version does not match, use the SD card tore brush the program can be, please ask us for the specific version.

5.3 No light

① Check whether there is an alarm prompt on the homepage, and whether the laser enabling system is ON;

② Check whether the trigger signal and safety lock signal of the monitoring page are displayed in green during cleaning;

③ Check whether the PWM, laser enabling and analog output of the monitoring page are normal during cleaning.

If the above conditions are normal, check the laser for abnormal alarm.

Example: the air supply wire but not the light, for the laser fault or laser wiring error. If neither air nor wire supply, the input signal maybe missing, see:

2.1.3 Controller signal interface 1.

5.4 suddenly stop producing light during processing

Check whether the safety ground lock and other alarm of the monitoring interface are normal.

Three-phase power wiring reference：

Note: Two-phase or three-phase electricity depends on the power supply required by the laser and the chiller, rather than the amount of wire harness.
