How to solve the problem that the laser marking machine has red light but no laser? What causes the laser marking machine to have red light and no laser? Today we have analyzed some reasons and the following solutions, hoping to help you solve laser marking The machine has red light but no laser problem. 1. The laser of the laser marking machine is not powered on. We can check whether the power supply of the laser marking machine is damaged. Check the 24-volt main control switching power supply. The positive and negative output is 24 volts. If the voltage is not normal, it will fail. Start the laser, resulting in the laser not running. 2. The laser is damaged. Check whether the laser is damaged. If you are not sure, you can rule out other related components, such as the laser control card and the vibrating mirror. 3. The control card is damaged. During the damage of the control card, the laser software cannot be connected to the laser, and the laser signal cannot be given, resulting in the inability to emit laser light. The red light of the laser marking machine is controlled separately and can be operated independently without any equipment connection. The movement of the red light is also given by the vibration lens of the laser, so the red light of the laser marking machine does not mean that the laser marking machine has a red light. Any problem with the standard machine, under normal circumstances, the red light is only connected to the current of 5V3. If the laser is not powered on, we can check the line first. If it is not the line problem, it is the power supply problem. Our solution is to replace the control power supply of the laser. We recommend using a stable power input system. You can use the 24 volt power supply from Taiwan Mean Well . The laser is often damaged. Laser marking machines generally have a two-year warranty. We can find the manufacturer to repair the laser. The biggest problem with the damage of the control card is that our laser shock lens cannot be connected to the industrial control computer. The damage of the control card is generally If it cannot be repaired, we recommend that you directly replace the control card. The control card is connected to a 5 volt power supply. We can also check whether the control card is powered on or the circuit is damaged. The problem that the marking machine has red light but no laser is nothing more than the above points. Only by checking different circuit control systems can we draw a conclusion. Whether it is a circuit damage or a mechanical failure, we also need to achieve the correct use process in the process of use. , we need to unplug the plug when not in use, so that the laser marking machine is completely powered off, so as to prolong the service life of the laser marking machine. Regarding the correct operation of the laser marking machine software, we enter the laser printer software after starting the laser marking machine. When exiting the software, we need to exit the software first and then turn off the laser marking machine, which can effectively protect the service life of the control card. The above is the problem that the marking machine has red light but no laser and some solutions, as well as some basic usage procedures that we have analyzed for you. I hope it will be helpful to you.
