Laser into the life, moon cake box, tableware, nameplate, key items such as application of the laser processing technology.
With laser deeply and widely applied, the manufacturer in laser engraving will often meet some problems difficult to solve, such as laser engraving machine carving, uneven?
Here are answers for you.
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 light spot 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.
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.
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 laser cutting machine, or laser engraving machine when cutting engraving effect is not uniform. （ On thermal lens phenomenon, may refer to former WeChat article) 。
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.
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 engraving is not uniform.
