Hello everyone:


If the following articles to maintenance part of the laser, CO2 laser marking machine dedicated galvanometer and semiconductor laser marking machine is the same, just different from the reflection of the lens, they two are: CO2 vibration of vibrating mirror lens material for Si commonly, the Chinese name for silicon, this material as a base, after polishing surface plating film or black gold plating on film.Semiconductor laser marking machine with the vibration of the lens is K9 glass as substrate, the surface also wants after polishing, plating a layer of 45 degrees of 1064 nm laser high membrane, the membrane in general can show a kind of color to light, you won't have to polishing and coating of the other side.Vibration, of course, gold plated film lens does not necessarily all of them are for CO2 laser, there are also some can directly for the semiconductor laser, gold plated film lens to 1064 nm semiconductor laser reflectivity can reach more than 99%,the laser marking machine price is resaonable.


Now we're in the theme, is marking the phenomenon of failure are as follows: in a mark, found no one axis rotation.
Produce CO2 laser marking machine vibrating mirror motor shaft fixed analysis of the cause of the problem are as follows: the highest possibility for the vibrating mirror driven plate or signal poor contact.Found after checking driver board fuse signal, by measuring the insurance is good, for the next step, if not fine, replacing the fuse, the next step to continue to check whether the signal contact is good, or to see motor line to have break, is it possible to break one line, for example, if not found abnormal phenomenon, on to the next step, if there is a problem to dispose of.The next will be the most important and key step is the X and Y signal exchange, found that after the replacement or another one channel signal output is not available, so you can be sure it is not possible is marking card and software or signal lines out of the question.


If or turn the motor shaft is not straight, so please use finger to touch the motor driven by the lens, if there is no lock, and under the condition of electricity, so be sure the motor or drive plate out of the question, if you want to measure is that a specific problem, can replace the X and Y motor to achieve a goal, but this approach only trial within a minute, please name is more appropriate, because the motor driver board and motor is necessary to do the best, if not matching can be a problem of a lot of big or small.If detected is marking card problem, then further testing as shown in the following: because of this machine adopts LS8001 card, and only the signal is not normal, all the way so afraid something wrong happened several touch switch card, measurement is found after all the way there is no output signal, so will the card to test, examination revealed it was DA card out of the question, finally found the problem of the original is a capacitance is broken,the prospect of laser marking machine for saleis very good.
