How to improve the accuracy of laser steel mesh

Source: Lin Chuan precision article author: Lin Chuan precision time: June 10, 2018 12:05 reading: 2771

Last century laser The technology has been used in the SMT steel mesh industry, in the development of SMT in the following decades Laser steel mesh SMT has become an important material industry. How to improve the precision of laser steel mesh to meet the miniaturization and high precision of SMT assembly industry is the direction of every SMT steel mesh enterprise. Linchuan precision has found that the main factors affecting the cutting quality are as follows:

1, spot size

The smaller the spot size, the higher the accuracy

2. Platform position accuracy

The position accuracy of the platform is that of the worktable. The higher the accuracy of XY axis is, the higher the accuracy of cutting steel mesh is

3. Thickness and material of steel sheet

The thickness and material of steel sheet determine the size and accuracy of steel mesh opening. Linchuan precision selects 304 imported materials with high flatness, which is not easy to deform and move when heated, and has higher accuracy

4. To achieve accurate control of focus.

The smaller the focal depth of the focusing lens, the smaller the spot at the focus. Therefore, the focus position can be effectively controlled on the metal surface to improve the cutting quality.

5. Optimize cutting and piercing technology.

Because the laser cutting machine belongs to thermal cutting, it is also necessary to first penetrate a small hole on the metal plate, and then the laser beam starts to cut the plate from the small hole.

6. Optimize nozzle design and air flow control technology.

In the process of sheet metal processing by laser cutting machine, oxygen is extruded by nozzle and acts on the surface of material to be cut together with laser beam. The basic requirements of air flow are large flow rate and fast speed, so as to ensure that there is enough oxygen to react with the material, and there is enough gas flow to blow away the slag.

The above content is the main method to improve the accuracy of SMT laser steel mesh. In fact, there are many unique using skills, which are related to the improvement of cutting accuracy. Linchuan precision has been constantly researching and summarizing, and will be used in many precision products, such as various LED backlight plate steel mesh, protective film isolation point steel mesh, etc. Have more friends can join us QQ discussion.
