During the processing of the laser marking machine, we need to adjust the focal length to achieve the best marking effect every time a product of a different specification is changed.

There are three main methods for adjusting the focal length in the past: continuous light test method, focal length measurement method and double red light point value method:. For the adjustment method, please refer to the article "Four kinds of focusing methods for laser marking machines". These three manual focusing methods are a headache for professional technicians engaged in the laser equipment industry, because they require patience and Time-consuming, for the outsider, manual focusing head is more painful, because manual focusing is slow and inefficient, and the focusing accuracy cannot be guaranteed, so that many scraps are generated when adjusting the machine. Moreover, there are many marking machines that cannot be connected to the production line, and product placement and focusing cannot be performed at the same time, which wastes a lot of time; some laser marking machines are not equipped with a digital display system, and the operating status of the equipment cannot be grasped at any time; some laser marking Although the machine is equipped with many functional mechanisms, the structure is complex and the shape is large, and it is not convenient to move. For this reason, Foshan Fulan Laser Technology Co., Ltd. independently developed a system ------ automatic focusing system according to market needs. It solves the problem of laser marking machine focusing.

The automatic focusing system can be configured in any laser marking equipment. The automatic focusing laser marking machine has the following advantages:

1. Automatically adjust the focal length: automatic focusing and marking can be realized by the automatic focusing system, even if there are slight differences in the thickness of the workpiece, the automatic focusing can be realized;

2. Simple structure, only need to install an automatic focusing system on the original laser equipment;

3. Higher marking accuracy;

4. Low cost: It reduces the waste of manpower and material resources and improves the efficiency of marking. Improve quality for customers, save time, and save costs for customers.
