Laser engraving technology slowly into People's Daily life, such as mobile phone shell design, light switches, car central plastic buttons, fonts (of
Design)
There are may be achieved by laser engraving technology.
In the laser carving patterns, processors often may encounter such a problem: & other;
Why don't laser carved the effect will be even?
”
1。 Vibration level of the machine is not set, the lens or mirror lens and parallel processing of mesa not
because both not levels, can lead to a laser beam through the field lens after reaches the extent of the inconsistency on the processing objects, the energy of the laser falls on the processing object will eventually have inconsistent energy density, at this point in the effect of heterogeneous materials.
2。 Laser output spot obscured, i. e. , a laser beam after the galvanometer and field lens flare have short, not enough round
laser output, fixed clamp and vibrating mirror is not set, lead to laser through some vibration lens flare obscured, after field lens focused on the frequency doubling piece of flare is a circle, this also is likely to lead to the effect is not uniform.
there is a kind of situation, namely the galvanometer deflection lens injury, when the laser beam through the lens damage area, can't reflect well. Therefore, the laser beam through the lens damage area is inconsistent with the lens no damage area of laser energy, in the ultimate role of laser energy is different also, so that the engraving effect is not uniform.
3。 Using partial JiaoBiao carved a range of content
because each focusing mirror ( A mirror) Has a corresponding depth of focus, and adopted the practice of deviation focus can easily lead to a wide range of carving patterns, the edge in the depth of focus point or beyond the scope of depth of focus, so it is easy to cause the effect of inhomogeneity. Therefore, the method of partial JiaoBiao moment that laser energy must be considered.
4。 A thermal lens
when laser through the optical lens ( Refraction, reflection) When the lens fever causes slight deformation. This deformation can make the laser focus focus, shorter focal length. If the machine is fixed, adjust the distance to the focus, the laser after a period of time, made by a thermal lens effect on the material of the laser energy density changes, resulting in engraving effect is not uniform. （ On thermal lens phenomenon, may refer to former WeChat article) 。
5。 Materials, such as membrane on the surface of the material thickness is not consistent or physical and chemical properties change
material to the laser energy response is sensitive. Usually under the same material, the laser energy to material damage threshold is certain. When the materials have different coating thickness, or some other physical and chemical treatment process is not uniform, will also cause the effect after the laser marking machine marking the uneven.
China laser laser equipment factory professional to provide you with one-stop industrial laser processing solutions, bring up a batch of star products, such as: MUV5 - B - A laser marking machine, uv CMA1530C - GH - Surrounded by A exchange platform for all optical fiber laser cutting machine and so on.
