Anyone who has used or been in contact with laser marking machines knows that this kind of equipment will involve the problem of focusing.

Fulan Laser will emphasize the importance of focal length when training users, because in the marking process, in order to achieve the expected marking effect, the parameters need to be adjusted first (different workpieces or different models or different marking The marking parameters will be different) in order to achieve the best results. Among them, the focal length is one of the important aspects of adjusting the machine. Only when the focal length reaches a certain distance can the perfect mark mark with high quality.

There are many ways to adjust the focus, do you know any? Next, please come and learn about it with Fulan Laser Technology:

①Focus measurement method: Let the equipment manufacturer inform and record the current focal length data of the equipment, and then each time the product is switched, one end of the steel ruler can be directly placed on the surface of the product, and the scale value refers to a certain reference surface on the field lens and shakes up and down To the scale data. This method is suitable for all laser marking machines, but there is a drawback that this method is not practical if the position of the product to be laser marked is concave or inappropriate to be inserted into the steel ruler.

②Continuous light emission test method: draw a square or circle about one centimeter on the marking software. After regular filling, adjust the laser energy to a larger value in the laser setting parameter bar, try to use low frequency as much as possible, and place the workpiece sample Mark the position, and then check the continuous marking, mouse click "continuous processing", then click "marking", shake the handle to adjust the Y-axis lift, test several times over and over, find the appropriate focal length, until the laser reaches When the energy on the workpiece is the strongest, the sound is the crispest, and the color is brightest, it is basically the focal length.

③Double red light to point value method: This method requires the device itself to have this hardware configuration when it leaves the factory. One or two oblique red lights should be installed next to the galvanometer or galvanometer, using some principles of right triangles and fixing them. One right-angled side of and two overlapping hypotenuses, find the other right-angled side of the plane where the focal length is located. Only need to shake up and down until the two red indicator points coincide to quickly find the focal length. Although this method is convenient and fast, it requires the equipment manufacturer to cooperate with this device, and if it is not adjusted properly, it is easy to cause misleading and form the wrong focal plane.

④Auto-focusing system: Foshan Fulan Laser Technology Co., Ltd. thinks about what customers think and worry about customers, and according to the needs of the market, independently developed a system ------ automatic focus system.

The automatic focusing system can be configured in any laser marking equipment. Only need to install an automatic focusing system on the original laser equipment, and realize automatic focusing and marking through the automatic focusing system, which can realize automatic focusing even if there is a slight difference in the thickness of the workpiece.

After the laser marking machine is equipped with an automatic focusing system, you no longer have to worry about focusing problems!

Based on the above, I summarize: the method of measuring focal length, the method of continuous light emission test and the method of double red light point value are all manual focusing: the speed is slow, the efficiency is low, and the focusing accuracy cannot be guaranteed; automatic focusing System: Fast speed and high precision.

The editor of Foshan Fulan Laser would like to remind you: "Continuous processing" is only used for focusing. After you have adjusted the focus, please remember to turn off "Continuous processing" before operating.
