The solution to the fault and the treatment of the light leakage of the laser marking machine


Author: Correct Pack -Laser Marking Machine Manufacturer

If the laser marking machine fails, please be sure to activate the emergency stop switch, and if a fire occurs, please cut off the power immediately. (1) It is forbidden to start the machine when the power supply voltage of the customer is unstable, otherwise a voltage stabilizer must be used. (2) The indoor environment will affect the life of the machine, especially the humid and dusty environment, which is easy to damage the reflector.

(3) The environment where the machine is located is free from pollution, strong electricity, strong magnetism and other interference and influence. (4) It is strictly forbidden to run the laser at full power for a long time. (5) It is strictly forbidden to start the machine without grounding. All the laser marking machines produced by our company, whether it is the shell or the casing, or the control cabinet, have artificial grounding. When the machine is at the customer's place, all parts of our machine are grounded , must be completely reliable to prevent static electricity from hurting people. If there is no ground wire at the customer, be sure to pull a ground wire again.

(6) Those who have not been trained by the manufacturer or those who have not been trained by old technology are prohibited from using the laser machine. (7) It is strictly forbidden for non-professional laser marking machine operators or those not authorized by the manufacturer to disassemble the machine without authorization to avoid accidents. (8) It is strictly forbidden to place any irrelevant high-reflective objects in the equipment. The reflected laser has no directionality, which is easy to cause unforeseen losses, so as to prevent the laser from being directly reflected on the human body or flammable objects, causing danger.

(9) The waste materials around the machine should be removed regularly to prevent too much waste from clogging the air outlet. At the same time, care should be taken to prevent the lens from being scratched and rusted, and it is also easy to cause a short circuit or laser discharge and ignition. (1) The light pen of the laser marking machine must not touch the beam when it is in operation. (2) The laser is the core of a laser marking machine, so it must be moved carefully to avoid breaking due to improper movement.

(3) During operation, once a fault is found, it must be stopped immediately to avoid casualties. (4) Do not start the laser marking machine when the water circulation is improper. When the UV laser marking machine (5) is about to turn off the marking machine, the current must be set at about 5A.

(6) During work, the working area should be higher than the operating area. (7) Keep the surface of the machine neat and clean. When the problem of light leakage of semiconductor laser marking machine occurs, how do we generally deal with it? Generally speaking, light leakage of semiconductor marking equipment is nothing more than two problems. The first aspect is the problem of acousto-optic modulation. The second aspect is caused by the confusion of the light signal from the marking card.

How do we determine the above two aspects? The general judgment method is as follows: If there is a phenomenon of light leakage all the time, such as when there is no marking, or when there is light leakage when marking, then this situation is the sound and light modulation. If there is a problem, the second one is that there is light leakage and misprinting during the marking process, and if the points of light leakage and misprinting are regular, then this is a problem with the laser marking card. The following mainly discusses the first case. If there is a problem with the acousto-optic modulation, it is generally nothing more than the following three aspects to check: . 1. There is a problem with the Q switch, such as the Q crystal is cracked, the internal circuit coil of the Q switch is broken, etc. Of course, it is necessary to check whether the cooling of the Q switch is OK, whether the surface temperature of the Q switch is the same as that displayed by the chiller, and whether the water flow is OK. Whether there is any foreign matter blocking the water pipe passage.

2. There is a problem with the Q power supply of the Q switch, also known as the Q drive. The best way is to replace one directly to see if it can be marked normally. After checking the problem of the Q drive itself, you can look at the Q drive. Whether there is an error code prompt, each code indicates a different possibility of the problem, please the majority of semiconductor laser marking machine users must ask the manufacturer to give you the problem index represented by the code, which is the manual of the Q drive itself. 3. There is a problem with the RF connection, for example, there is a problem with the wire, the interface between the RF cable and the Q switch or the interface between the RF cable and the Q drive (usually a BNC head) is loose or falls off.
