Laser marking machines use laser beams to make permanent marks on the surfaces of various substances. The effect of marking is to expose deep substances through the evaporation of surface substances, so as to carve beautiful patterns, trademarks and characters. The laser marking machines are mainly divided into CO2 laser marking machines, semi conductor laser marking machines, optical fiber laser marking machines and YAG laser marking machines. The laser marking machines are mainly used in some occasions that require more precision, It is used in electronic components, integrated circuits (IC), electrical appliances, mobile phone communications, hardware products, tool accessories, precision instruments, glasses, watches, jewelry, auto accessories, plastic keys, building materials, and PV laser marking machine C pipe.
Laser marking is to use the laser beam to make permanent marks on the surface of various substances. The effect of marking is to expose the deep substances through the evaporation of surface substances, or "carve" traces through the chemical and physical changes of surface substances caused by light energy, or burn some substances to show the patterns and characters to be etched.
The laser marking machine has no troubleshooting method for laser output. It is inevitable to encounter equipment failure when using the laser marking machine, which results in no laser output. What is the matter? You can deal with this situation from the following process, so that the laser marking machine can resume operation as soon as possible, and the normal output of optical fiber laser marking machine.
Method 1: Check whether the laser marking machine is operated incorrectly. If so, shut down the device and restart it.
Method 2: Carefully check the abnormal problems of the laser marking machine, mainly including the following: the sound during operation, such as the sound of the vibrating lens, the sound of the laser, the alarm sound of the equipment itself and the alarm sound of the water chiller. If the voltage is abnormal, you can simply use a multimeter to measure it. Generally, if the voltage is low, there will be no laser, and whether the computer software and computer have signs of poisoning, The startup speed is slow, and it stops on an interface for a long time after startup.
Method 3: On the premise that the first two conditions are eliminated, turn on the laser cavity of the laser marking machine, use the dimmer, and check whether there is laser output at the laser output port. If there is laser, the following accessories are the problem: galvanometer, beam expander, red light combining mirror and field mirror. Otherwise, if there is no laser, you can go to the next step.
Method 4: If there is no laser in the previous step, there are two possibilities: first, there may be a problem with the laser of the laser marking machine; second, there may be a problem with the signal controlling the laser. This step is to confirm the above two possible equipment failure accessories, and detect the laser input signal of the laser marking machine. If there is a signal, there is a problem with the laser; if there is no signal, go to the next step, the ultraviolet laser marking machine.
