Latest company news about Is the "red light adjustment" of the laser marking machine really important?

Many manufacturers engaged in laser marking processing will ask when purchasing equipment: Does this machine have a red light adjustment function? What exactly does this "red light adjustment" do? To this end, the editor of S&A Special Domain Chillers specially consulted some equipment manufacturers, sorted out several important roles, and shared them with you.

1. Adjust the optical path of the resonant cavity

The working principle of the resonant cavity is based on the interference of multiple beams in the cavity, and a basic condition for interference is the coincidence of the beam space. This requires us to very accurately control the direction of the beam to couple into the cavity, that is, light-cavity coupling. For example, semiconductor laser marking machine.


2. Positioning

Only by setting the marking position, can the processing and production be carried out efficiently. As the indicator light for marking and positioning of laser marking machine, it can be divided into marking focus indication, 9-point indication of marking pattern, indication of length and width range of marking pattern, and overall marking pattern according to different marking software. Various indication methods such as analog indication.

3. Focus
The red light can also be used as the focus point of the laser marking machine, that is, the indication of the marking distance (this is sometimes the red light does not display, and sometimes the red light appears, but only the red light is flickering. It is dark, but the phenomenon of not showing light). The overlapping distance of the two red light points is exactly the distance of the marking airport mirror. In this way, there is no need to use a steel ruler to measure the marking distance every time the product is changed. The operation steps are reduced and the operation steps are improved. Marking speed.

The manufacturer also reminded:

One thing to pay special attention to: turning on the red light adjustment of the laser marking machine requires the operator to have a certain understanding of the equipment. For example, the general red light adjustment is set on the marking software, and it can be turned on by pressing F1. If you only find that the galvanometer is moving and there is no red light coming out, then check first to control whether the red light is a mechanical switch If it is not turned on, check whether the power of the red light is turned on. Use a multimeter to measure whether there is a 5V voltage between the two red and black bars of the red light indicator. If it is a 5V voltage and no laser output, then the red light indicator is required. Replaced.

At present, some laser marking machine manufacturers do not have this function in order to save costs. When choosing a laser marking machine, you must pay attention to this point. A complete laser marking machine must include a red light indicator system. Do you have all the equipment?
