What are the maintenance methods of CO2 laser cutting machine engraving machine without light? Sometimes we wait for the manufacturer to come out after the sale without waiting for these little knowledge, which wastes precious time. In fact, these are not big problems, as long as you read the knowledge below, you can solve it by yourself!The co2 laser cutting machine suddenly does not emit light during the cutting process1. Whether the laser tube emits light or not, the wire on the motion control card is loose, or the motion control card is broken (replace the board). No light, the laser power supply is broken. (In rare cases, the laser tube is broken) (Check whether there is a spark at the high-voltage end of the laser tube, the ignition will easily burn the laser power supply and the electronic components of the board). If the fan of the laser power supply does not turn, use an electric pen to test the 220V port of the laser power supply to see if there is electricity. There is electricity, the laser power supply is broken. (repair or replace the power supply); no power, check the laser power switch and circuit.2. There is no light when the machine is turned on, and the operator is not very familiar with the operation process of the machine.3. Check whether the water tank alarms3.1 No alarm, check whether the laser power fan is running. The fan of the laser power supply rotates, and the laser power supply is short-circuited with a wire.3.2 Alarm, connect the water inlet and outlet at the back of the water tank with a water pipe, and the water tank is powered on to see if an alarm is issued. If you call the police, the tank is broken. If it is not alarmed, it means that the water path of the laser tube is not smooth. Check whether the water tube is bent or pressed by something, and whether there is any debris in the water in the water tank (replace the pure water in the water tank).To check the following aspects1. Whether the light path is normal. (Press the light to see if the laser tube is bright, if it is bright but the laser head is not bright, there is a problem with the optical path)2. Whether the laser power switch is turned on.3. Whether the water tank is open.4. Whether the power of the machine operation panel is correct. Or whether the computer software parameters are correct.
The laser marking machine is a machine used to mark the surface of the material. There are many types of laser marking machines. According to the laser, they can be divided into CO2 laser marking machines, semiconductor laser marking machines, etc.; according to the wavelength, they can be divided into deep ultraviolet laser marking machines and green laser marking machines. Laser engraving machine and laser marking machine have similar functions, but there are obvious differences in definition, applied material, depth and thickness, price, etc. Let's take a look at the laser marking machine.1. What is a laser marking machineLaser marking machine is a mechanical device that uses a laser beam to permanently mark the surface of various substances. The working principle of the laser marking machine is to expose the deep material through the evaporation of the surface material, or to "engrave" traces through the chemical and physical changes of the surface material caused by light energy, or to burn off part of the material through light energy to show the required Etched pattern, text.Laser marking machines are mainly used in some occasions that require finer and higher precision. Used in electronic components, integrated circuits (IC), electrical appliances, mobile communications, hardware products, tool accessories, precision instruments, glasses and clocks, jewelry, auto parts, plastic buttons, building materials, PVC pipes.2. What types of laser marking machines are there?There are many types of laser marking machines, which are mainly classified according to two factors: laser and wavelength:1. Press the laserLaser marking machines can be divided into: CO2 laser marking machines, semiconductor laser marking machines, YAG laser marking machines, and fiber laser marking machines according to different lasers. According to the different laser visibility, it is divided into: ultraviolet laser marking machine (invisible), green laser marking machine (visible laser), infrared laser marking machine (invisible laser).2. By wavelengthAccording to the different laser wavelengths, it can be divided into: deep ultraviolet laser marking machine (266nm), green laser marking machine (532nm), lamp pump YAG laser marking machine (1064nm), semiconductor side pump YAG laser marking machine, semiconductor terminal Pump YAG laser marking machine (1064nm), fiber laser marking machine (1064nm), CO2 laser marking machine (10.64um).3. What are the differences between laser engraving machine and laser marking machine1. Different definitions(1) A laser engraving machine is a technological device that uses lasers to engrave materials that need to be engraved. Laser engraving machines can also be called laser cutting machines, laser engraving machines, etc., which shoot lasers on almost all materials such as wood products, acrylic grains, plastic plates, metal plates, and stone.(2) The laser marking machine uses a laser beam to evaporate the surface material to expose the deep material, resulting in the chemical change and physical change of the surface material to engrave traces, or to burn off part of the material through light energy, showing the required etching. graphics and text.2. Different application materials(1) Laser engraving machines generally engrave or cut non-metallic materials.(2) Since the laser marking machine does not require deep engraving, it only realizes the marking by marking the logo and name. Most of the metal and non-metal materials can basically be marked. Use very little cutting.3. Different depth and speed(1) The laser engraving machine can engrave or cut in large stroke size, and the depth is far more than that of the laser marking machine.(2) The speed of the laser marking machine is relatively fast, generally reaching 7000mm/s.4, the price is different(1) The price of the laser marking machine varies from tens of thousands to hundreds of thousands depending on the corresponding models selected for different materials.(2) Laser engraving and cutting machine, the price of low power is much cheaper than that of laser marking machine.
There are many types of laser cutting machines. According to the cutting materials, they can be divided into metal laser cutting machines and non-metallic laser cutting machines. According to laser types, they can be divided into fiber laser cutting machines, CO2 laser cutting machines, etc. According to the laser output power classification It can be divided into high-power laser cutting machine, medium-power laser cutting machine, and low-power laser cutting machine. Different types of laser cutting machines have different uses, let's take a look at it together!1. What types of laser cutting machines are there?1. According to the type of cutting materialThere are two types of metal laser cutting machines and non-metallic laser cutting machines. This is a good distinction. Generally, a metal laser cutting machine is used when metal materials are required, and a non-metal laser cutting machine is used when cutting non-metallic materials.2.
