The marking speed of laser marking machine is usually one of the problems we are concerned about, because it is related to saving labor costs and improving production efficiency. Let us look at how to improve the marking speed of laser marking machine.

 

One or four fillings are most suitable for selection;

 

1, two-way filling: marking efficiency, the effect is good.

 

2, shape fill: only use the fine graphics, fonts will be used, the efficiency is similar to the bow fill.

 

3, one-way filling: marking efficiency is the slowest, rarely used in actual processing.

 

4, bow-shaped filling: marking efficiency is the highest, sometimes there will be wiring, uneven problems, marking the fine graphics, fonts, the above problems will not occur, so bow-shaped filling is preferred.

 

The above four filling methods are different, and can be changed according to the actual marking requirements, and the corresponding filling method can also improve the marking efficiency. If you do not pursue the marking effect of the details, it is recommended to use the bow fill to significantly improve the speed of marking. If you want to have both sides of the two-way fill is a very good choice.

 

Second, choose its better high-speed galvanometer;

 

Under normal circumstances, the galvanometer scanning speed can reach up to 3000mm/s, but a good high-speed galvanometer can scan tens of thousands of times per second (you need to know more than zero and less zero which means this). In addition, when using a normal galvanometer to mark small graphics or fonts, it is prone to deformation, and the effect must be ensured by reducing the scanning speed.

Third, the appropriate field lens;

 

The larger the focal length of the field lens is, the larger the focusing spot is. At the same spot overlap rate, the filling line spacing can be increased, thereby improving the marking efficiency.

 

Note: The larger the field lens, the smaller the power density, so increase the fill line spacing to ensure sufficient marking energy.

Fourth, clever set delay;

 

Different fill types are affected by different delays, so reducing the delay independent of the fill type can also improve the marking efficiency.

 

1. Bow-shaped filling and back-shaped filling: mainly affected by the corner delay, which can reduce the opening delay, the closing delay and the ending delay.

 

2, two-way filling, one-way filling: mainly affected by the opening delay, off light delay, can reduce the corner delay and end delay.

 

But also pay attention to the fact that the thick graphics and fonts are less affected by the delay, and the delay can be appropriately reduced. Fine graphics and fonts are greatly affected by the delay, and the delay can be appropriately increased.

 

5. Other channels;

 

1. Check the Average Distribution Fill Line.

 

2. For marking rough graphics and fonts, you can remove the enable contour and raise once.

 

3. When the effect is allowed, you can increase the "high speed" "jump speed" and decrease the "jump delay".

 

4, marking a large range of graphics, appropriate into several parts of the fill, can effectively reduce the jump time and improve the marking efficiency.
