Laser engraving machine is also a kind of laser marking machine. In the process of operation and maintenance, we should be familiar with the method, maintain carefully, and let the machine perform more strict work. Xiaobian secretly visited the industry leaders and found 12 secrets of using laser engraving machines that experts in the field of laser engraving would not tell you. Let's talk about them:
1. The laser engraving machine is well grounded
The laser power supply and machine need good grounding protection, and the ground wire must be a special ground wire below 4 Ω. Grounding requirements are as follows:
(1) It can ensure the normal operation of the laser power supply.
(2) It can prolong the life of the laser tube.
(3) It can prevent the machine from jumping due to external interference.
(4) Prevent accidental circuit damage caused by high-voltage discharge.
2. The water cooling of the laser engraving machine must be uniform.
Whether you use tap water or circulating water pump, the water needs to flow continuously. The heat generated by the coolant evaporation laser tube. The higher the water temperature, the lower the light output (the water temperature should be 15-20 ° C). If the water is blocked, the heat accumulated in the laser cavity will damage the tube tip and damage the laser power supply. Therefore, it is always a good idea to check whether the coolant is even. If the water pipe suddenly bends or topples (dead bends), causing damage to the water pump, it must be repaired in time to avoid damage to the equipment due to power failure.
3. Clean and maintain with good ventilation and continuous drying
Cleaning and maintenance of the machine are prerequisites for normal operation of the machine. People's joints are not flexible, how can they move? Machine tool control is also the key to accuracy. After each operation, it must be cleaned, kept clean and lubricated. The bearing also needs to be lubricated regularly to make the transmission flexible, match with the machine and extend the service life of the machine.
4. Ambient temperature and humidity
The ambient temperature shall be 5-35 ° C. Special note: Please follow these guidelines when using frost.
(1) The water circulating in the laser tube must be antifreeze and completely drained after power failure.
(2) When starting, the current laser must be warmed up for at least 5 minutes before starting to work. In rainy season or humid environment, the laser power supply may need to be heated for a long time. After removing moisture, high voltage can be used to prevent damage to the high-voltage circuit.
5. Use the high-voltage laser button correctly.
When the laser high-voltage button is activated, the laser power supply enters the standby mode. In case of "passive light output" or computer error, laser will be emitted, which will damage people or objects unintentionally. Therefore, the "Laser High Voltage" must always be turned off (the laser power cannot be turned off). To avoid accidents, the user must not leave the machine without authorization when the machine is running It is recommended to work continuously for less than 5 hours, including 30 minutes of rest.
6. Keep away from strong equipment and high vibration equipment.
Sudden loud disturbances are rare, but should be avoided as far as possible, as they can cause machine failure. Therefore, the use of large electric welding machines, large electric mixers, large power transmission and transformation equipment and other items should be avoided. The vibration caused by the short distance movement of heavy vibrating equipment such as forging presses and machines is not to say that it is extremely unfavorable for accurate carving.
7. Lightning protection
If only the lightning protection device of the building were reliable. The first point "good grounding" in this section is also helpful for lightning protection.
Special tips: In areas with unstable AC power supply (such as voltage fluctuation of more than 5%), install at least 3000W regulated power supply to avoid damage to circuit or computer caused by sudden surge.
8. Keep the stability of PC controller
Computer control is mainly used to control the engraving system. Do not use it for any purpose other than installing the required graphic design software. The computer has its own network card and anti-virus firewall, which greatly affects the speed of the controller. Do not install an antivirus firewall on the controller. If the network card is required for data transmission, please turn off the network card before starting the engraving machine.
9. Railway maintenance
When the guide element moves, a lot of dust will be generated. Maintenance method: first, wipe off the original grease and dirt on the guide rail with a cotton cloth, and then apply grease on the surface and side of the guide rail.
Maintenance cycle: about one week.
10. Fan maintenance
After the fan runs for a period of time, a large amount of dust will accumulate in the fan and exhaust duct, which will affect the performance of the fan and produce a large amount of smoke that cannot be removed
Maintenance instructions: Loosen the clamp connecting the exhaust pipe and fan, remove the exhaust pipe, and clean the dust on the exhaust pipe and fan.
Working period: about one month.
11. Tighten the screws
After the mechanism operates for a period of time, the connecting screws of the mechanism will be loosened, which will affect the stability of the mechanical mechanism. Maintenance method: Use the provided tools to tighten the screws one by one.
Working period: about one month.
12. Lens maintenance
When the machine runs for a certain period of time, the working environment will cause a layer of dust on the lens, which will reduce the reflectivity and transmissivity of the mirror, and ultimately affect the capacity. Working Laser.
Maintenance instructions: Use a degreasing cotton swab dipped in ethanol to gently wipe the lens surface to remove dust.
In other words, we need regular maintenance to greatly improve the working life and efficiency of our laser engraving machine.
Laser engraving machine is no longer a new thing in the industry. As a new star in the field of industry and manufacturing, the application of laser engraving machine in many industrial fields is beyond imagination. If you keep updating this hardware, you can do many subtle pranks. I don't think everything is manual. Like some objects we encounter every day, it is convenient to use CNC laser equipment.
Inspection items during manufacturing and how to use laser engraving machine
First, prepare the carving products.
The process of laser engraving machine does not mean that you cannot carve without mastering it. Materials to be used, such as shape, material and size, shall be prepared in advance. This is the basic preparation. Notice that the appearance is very strange. We suggest you consult the manufacturer first. Then proceed to the next step.
Second, specify the content of the seal.
For example, once you decide what you want to record, you need to preset what you want to record. B. What effect do you use? The result of the engraving content is very important, otherwise the content is incorrect and difficult to change
Third, it forms the thread size.
In the processing of handicrafts, the requirements for product carving are relatively high, but there are certain problems in carving technology. The purpose and understanding of carving should be formulated at the beginning of carving.
4、 Accurate engraving performance
Once you are ready, you can make a small incision. Radiation laser engraving machine adopts automatic processing method. The whole process is very simple and convenient, and you can expect the results.
The advantages of manual processing laser engraving machine are obvious. After using the machine, it is easy to plan carefully first. Customers can use their methods to create something more boring and confusing. The best way is to create a unique laser engraving machine through shopping and telephone.
