Do You Want To Know The Operation Process And Safety Specifications Of Laser Engraving?

In order to the personal safety of the operator and the good operation of the machine and equipment, the use of laser engraving equipment must be checked and used in accordance with the specifications, and good specifications must be formed in the long-term work to achieve standardization.

Laser engraving machine operation process

1. Check beforehand

Check the laser head, check the focusing mirror, and check the cooling system and exhaust system is smooth.

2. boot debugging

Open the gas cylinder valve, open the gas switch, open the cooling device, open the equipment, and then turn on the equipment switch, and laser switch, open the key switch, check whether the signal light has a warning, if so, check the alarm according to the signal light indication.

3. Prepare for processing

Place the materials that need to be carved, open the laser board card, set the corresponding processing parameters according to the material, including laser power, laser speed, focus size, and other parameters, simulate engraving on the sample, adjust the parameters according to the process requirements, and then start the proofing test.

4. Proofing and testing

Start proofing test, engraving through the information displayed on the laser board card to determine whether the processing time and power are reasonable, engraving is completed to check the finished product, to see if there are engraving discoloring, material blackening, uneven slit, cut-through, and other problems.

5. Process adjustment

According to the situation of the sample, the processing process is adjusted and then continues to toilet until the carved product meets the process requirements.

Manual laser welding operation specification

1. The operator must be trained, familiar with the equipment structure, and performance, and master the knowledge of the operating system.

2. According to the regulations to wear good labor protection supplies, one must wear protective glasses that meet the regulations.

3. Do not process a material before it is clear whether it can be irradiated or heated by laser, so as to avoid the potential danger of smoke and vapor.

4. Keep fire extinguishers within easy reach; Turn off the laser machine or optical brake when not producing; Do not place paper, cloth, or other flammable materials near an unprotected laser beam.

5. The processing of abnormal, should be immediately shut down, troubleshooting in time or reported to the supervisor.

6. Keep the laser machine, bed, and the surrounding site clean, and orderly, no oil, workpieces, materials, or waste stacked according to regulations.

7. Maintenance to comply with high-pressure safety procedures. Every 40 hours of operation or weekly maintenance, every 1000 hours of operation, or every six months of maintenance, in accordance with the regulations and procedures.

8. Do not let the gas cylinder in the sun or close to the heat source. When opening the bottle valve, the operator must stand on the side of the bottle's mouth.

Laser engraving machine 12 notes Laser engraving machine will also be a kind of laser marking machine. In the use and maintenance needs to master the method and careful maintenance, in order to make the machine more stable and play its role.

1. Laser engraving machine good grounding laser power supply, the machine bed body must have good grounding protection, and ground wire application of less than 4Ω special ground wire. The need for grounding is:

(1) Can ensure the normal operation of the laser power supply,

(2) Can extend the service life of the laser tube,

(3) can prevent external interference caused by machine jumping,

(4) Prevent accidental circuit damage caused by high voltage discharge.

2. The cooling water of the laser engraving machine should be unobstructed, whether it is using tap water or a circulating water pump, the water flow must be kept unobstructed. Cooling water is to take away the heat generated by the laser tube, the higher the water temperature, the lower the optical output power (15-20℃ water temperature is better); When the water is cut off, the heat accumulated in the laser cavity will cause the tube end to burst and even damage the laser power supply. Therefore, it is necessary to check whether the cooling water is smooth at any time. When the water pipe is hard broken (dead bend) or falls off, and the pump fails, it must be repaired in time to avoid power reduction or even damage to the equipment

3. cleaning and maintenance, good exhaust, cleaning and maintenance of the machine tool at any time, is a necessary condition for the normal operation of the machine tool. Imagine how people can move when their joints are not flexible. In the same way, the guide rail of the machine tool is a high-precision core component, which must be wiped clean after each work is completed and kept smooth and lubricated; The bearings should also be regularly filled with oil so that the drive can be flexible, the processing is accurate, and the service life of the machine tool can be extended.

4. Ambient temperature and humidity Ambient temperature should be in the range of 5-35 ° C. Special attention is: if used in an environment below freezing point, it must be done:

(1) Prevent the circulating water in the laser tube from freezing, and the water must be thoroughly illuminated after shutdown;

(2) When starting, the laser current must be preheated for more than 5 minutes to work, in rainy days and humid environments, the laser power supply needs to be preheated for a longer time, and the high voltage can be added after the moisture is indeed discharged to prevent the breakdown of the high voltage circuit.

5. The correct use of the "laser high voltage" key "laser high voltage" key to dial, the laser power supply is in a standby state, encounter "manual light" or computer misoperation, will emit a laser, unintentionally hurt the injury. Therefore, it is required that each completion of a piece of work, such as non-continuous processing, should be turned off at any time "laser high voltage", (laser current can be turned off), and the operator is prohibited from leaving the machine when it is working, so as to avoid accidents, it is recommended that the continuous working time is less than 5 hours, and the middle can rest for 30 minutes.
