Laser engraving machine laser head installation?

The laser engraving machine manufacturer will send special personnel to install the equipment. The installation also includes the installation of the laser head, and debugging is required after installation.
What are the precautions for laser engraving machine laser head installation?

1. The laser engraving machine should be placed horizontally on the table and should not be tilted.

2. The laser engraving machine should prevent strong vibration. When moving, fix the cart and trolley first to prevent the optical path from shifting or cracking the laser.

3, the exhaust pipe should be connected to the outdoor no impact, and keep well ventilated, often wipe the ash inside the fan and machine pipe

4. There is high voltage inside the laser engraving machine. Non-professional technicians must not open the case for maintenance to prevent electric shock.

5. If the laser engraving machine is used for the first time or after moving the position, please check whether the high-voltage line is off to prevent electric shock.

6, laser engraving machine exhaust fan, cooling water pump is AC220V/50HZ electricity o

7, the engraving machine ground wire must be well grounded

8. When working on the laser engraving machine, it is necessary to prevent the staff or other personnel from reaching out or using the eyes to prevent the laser from injuring or injuring the eyes. It is best to buckle the cover.

9. Please avoid the water inside the equipment or the working environment is too humid. The machine should be placed in a dry, well ventilated place.

10. It is strictly forbidden to disassemble various connectors with power.

11. The lens inside the engraving machine should be cleaned with anhydrous ethanol or acetone in time, and should be lightly rubbed. After polishing, adjust the light path.

12. When using, ensure that the cooling water circulation is good, and the water quality is clean. If there is yellow water and dirty water, it should be changed in time to avoid the laser tube cooling is not good and cause cracking.

13, pay attention to prevent freezing due to cooling water, cold weather in the north should pay special attention to winter is best to replace the car with antifreeze, the temperature is too high, scale or dirt blocked mechanical impact and other reasons caused by laser damage.

14. Take care to prevent corrosion and damage caused by excessive moisture in the internal parts of the chassis. Therefore, after each workpiece, clean the machine and keep the machine clean and tidy.

Instructions for using the laser engraving machine after laser head installation?

1, the operation panel description

Power switch: used to turn the laser engraving machine on or off

Current indication: used to indicate the current of the engraving machine

Current adjustment: use this potentiometer to adjust the current during engraving according to the current indication.

Illumination switch: used to start or turn off the illumination inside the laser engraving machine (several machines do not have this switch)

Laser switch: used to control whether the laser is illuminated. When the stamp is engraved, the switch is on (ie pressed).

Test switch: When the switch is pressed, the laser will emit light. At this time, according to the ammeter display data adjustment potentiometer is used to adjust the current when engraving. This switch is only used to debug the machine and view the current when engraving. It needs to be disconnected when the machine is working normally, and the computer will automatically control the engraving.

2. When using, start the cooling water pump, then start the laser engraving machine and ensure the cooling water circulation.

3. Start the engraving system typesetting software, design the image to be engraved, and set the engraving position. (Refer to the software manual for the specific steps) Fix the engraving chapter material on the fixture so that the material plane and the fixture plane are on one plane. Engraving output (It should be noted that the rubber material is prepared for a small piece of newspaper to be soaked in water, tiled on the material, prepare a brush to insert into the water when engraved, and gently rub it on the newspaper.)

4, the current adjustment should be based on different seal black and process requirements to adjust the current.

What should I do if the laser engraving machine does not return after the laser head is installed?

1, system problems, check the bottom line contact is good, then re-install the system to see how effective;

2. Contact the laser engraving machine manufacturer for technical support services and after-sales service, and then you can contact the agent to solve the problem.

Is the laser engraving machine running after the laser head is installed?

1. The laser tube has light, but there is no light at the laser head.

2. The laser tube has light or no light, but the ammeter has instructions.

3, the laser tube is not light, and the ammeter is not indicated.

What should I do if the laser engraving machine does not emit light after installation?

All of our inspections or inspections have a major premise: the high and low voltage electrodes of the laser tube are completely wired and the wiring is in good contact. Next we analyze step by step:

First, check if the * spot can be shot at the frame.

Use the dimming paper to repeatedly paste the three layers, block the lens of the * frame, and then press the spot on the control panel (provided that the laser power switch is turned on, the potentiometer is turned clockwise to * (the 350 model device generally does not have a potentiometer)

A. If there is a laser-burning spot on the dimming paper, it can be determined that there is a problem with the optical path of the device. You need to adjust the optical path by referring to the tutorial on adjusting the optical path.

B. If there is no laser-burning spot on the dimming paper, but the inside of the laser tube is observed by a naked eye, in general, the laser tube is broken. (There is a special case where the installation direction of the laser tube is reversed, which can also cause this phenomenon to occur.)

Note: When installing the laser tube, remember that the nearest end of the * frame is the low voltage end.

C. If there is no spot on the dimming paper, no beam will be generated inside the laser tube. Please refer to the second item below.

Second, if there is no beam generated in the laser tube, we should check: laser switch, potentiometer, ammeter.

1. First make sure the laser control switch is on.

2. The potentiometer rotates clockwise to *degree.

3. Observe the current meter indication.

If the ammeter pointer is indicated, in general we can conclude that the laser tube is broken.

If the ammeter pointer is not indicated, we continue to check:

A. Observe the power display on the control panel. If the power value is lower than 10%, adjust the minimum power to 50%, then repeat the observation of the ammeter indication, and whether there is laser light in the laser tube and the * frame.

B. If the power value on the control panel indicates no less than 50%, then there are two cases:

First, the laser power signal line on the main board and the terminal on the laser power supply may loose or fall off, causing the laser power supply to not receive the illuminating signal transmitted from the main board.

Second, the laser power supply is damaged.

It is difficult to judge. We need to check other inspection items that do not involve ammeters and potentiometers one by one, eliminate other causes, then press the spot on the control panel several times, then touch the laser tube with low voltage or ground wire. The high-voltage connector, if there is a spark, can be judged that the laser tube is damaged. If there is no spark, it can be judged that the laser power supply is damaged.
