If any mechanical equipment wants to last for a long time, maintenance is the first element. If you don’t pay attention to maintenance, no matter how good the equipment is, it is not durable, just like a car needs regular maintenance. The same is true for laser equipment. The main components of the laser cutting machine can be divided into five types: light source system, dust removal system, transmission system, cooling system, and circuit system.
The main parts of Richang that need to be maintained are: cooling system (to ensure constant temperature effect), dust removal system (to ensure dust removal effect), light path system (to ensure beam quality), and transmission system (focus on ensuring normal operation).
1. Cooling system maintenance
The water inside the water cooler needs to be replaced regularly, and the general replacement frequency is one month. The water chiller is used as circulating water to cool down the laser and other parts of the equipment. Long-term use of water will reduce the water quality and easily form scale, which will block the waterway and reduce the water flow and reduce the cooling effect. Therefore, regular water replacement is treated as the primary problem. Choose distilled water as much as possible for water, or deionized water if there are no conditions. Various manufacturers have requirements for water quality, so remember to meet the requirements, otherwise long-term use of water that does not meet the standard will cause fouling inside the laser.
2. Maintenance of dust removal system
Long-term use of the fan will accumulate a lot of solid dust in the fan, make the fan generate a lot of noise, and it is not conducive to exhaust and deodorization. When the fan suction is insufficient and the smoke is not smooth, first turn off the power, remove the air inlet and outlet pipes on the fan, remove the dust inside, then turn the fan upside down, and pull the inner blades until they are clean , And then install the fan.
3. Maintenance of light path system
The laser light is emitted from the laser head after being reflected and focused by the lens. After the device has been running for a period of time, some dust will stick to the surface of the lens. This dust will have a great impact on the reflectance of the lens and the transmittance of the lens, which will reduce the power of the laser. At this time, it is necessary to clean the lens. The dust. However, you must be careful when cleaning up. The lens is a fragile item, and you must handle it gently. Do not touch the lens with sharp or hard objects.
The steps and precautions for cleaning the lens are as follows: First, use absorbent cotton dipped in ethanol to wipe carefully along the center to the edge of the lens. The lens needs to be wiped gently, and the surface coating should not be damaged. , Be sure to keep the concave surface down when installing the focusing lens. In addition, the use of ultra-high-speed piercing should be minimized at ordinary times, and the use of conventional piercing can prolong the service life of the focusing lens.
4. Drive system maintenance
In a laser cutting machine, the transmission system is equivalent to a person's hands and feet. The transmission system directly affects the normal operation and service life of the equipment. The laser cutting machine will generate smoke and dust during the long-term cutting process. The fine smoke and dust will enter the equipment through the dust cover and adhere to the rail rack. Long-term accumulation will increase the rail teeth. The wear of the rack, the rack guide is originally a relatively precise accessory, and it will cause damage to the slider and the gear after a long time. Therefore, the guide rail rack should be cleaned regularly. After cleaning the dust attached to the guide rail rack, grease the rack and lubricate the guide rail with lubricating oil.
5. Working environment requirements
The production workshop where the equipment is placed must be kept dry and well ventilated. The indoor temperature should preferably be between 4-33 degrees. Prevent condensation on the equipment in summer and take anti-freezing measures in winter. The equipment should be placed far away from places with electromagnetic interference, far away from places with large power and strong earthquakes. The interference of large power will cause the equipment to malfunction from time to time. Although it is not inevitable, it must be prevented. Therefore, the equipment should not be placed with large electric welding. Nearby equipment, such as machines, giant electric mixers, etc. Not to mention strong vibrations, ground vibrations will obviously cause deviations in the accuracy of laser engraving.
6. Some other precautions
During the operation of the equipment, the operator should always observe the operation of the equipment. If there is an abnormality, immediately stop the operation of the equipment, cut off the power supply, and report to a professional to inspect and repair the equipment in time. Do not disassemble and repair the equipment without permission. Perform regular statistics on the use of the equipment, and if there is an effect deviation, it should be replaced in time to prevent it before it happens. If you don't know whether the material can be processed, do not process it, so as to avoid potential dangers and damage the laser equipment.
