First of all, for a fixed marking pattern, the factors that affect the marking efficiency can be divided into the equipment itself and the processing material, so it can be concluded that the filling type, field mirror, galvanometer, delay and other factors ultimately affect the marking efficiency. The second is how to improve the marking efficiency measures:. One, choose the most suitable one from the four types of filling.
1. Two-way filling: the marking efficiency is the highest, and the effect is good. 2. Back-shaped filling: it is only used when marking thin graphics and fonts, and its efficiency is similar to that of bow-shaped filling. 3. One-way filling: the marking efficiency is the slowest, and it is rarely used in actual processing.
4. Bow-shaped filling: the marking efficiency is the highest, sometimes there will be connecting lines, unevenness, and when marking thin graphics and fonts, the above problems will not occur, so the bow-shaped filling is the first choice. The above four filling methods are different, and can be changed according to the actual marking requirements. Choosing the corresponding filling method can also improve the marking efficiency. If you do not pursue the detailed marking effect, it is recommended to choose the bow filling to significantly improve the marking. If you want to have both, bidirectional filling is a very good choice. Second, choose a better high-speed galvanometer.
Under normal circumstances, the scanning speed of the galvanometer can reach up to 3000mm/s, but a better high-speed galvanometer can scan tens of thousands of laser marking machines per second (you need to know what more zeros and less zeros mean). In addition When using ordinary galvanometers to mark small graphics or fonts, deformation is prone to occur, and the scanning speed must be reduced to ensure the effect. Laser marking machine galvanometer. Third, a suitable field lens.
The larger the focal length of the field lens, the larger the focused spot. Under the same spot overlap rate, the filling line spacing can be increased, thereby improving the marking efficiency. Remarks: The larger the field lens, the lower the power density, so it is necessary to increase the filling line spacing while ensuring sufficient marking energy. Laser marking airport mirror.
Fourth, cleverly set the delay. Different filling types are affected by different delays, so reducing the delay that is not related to the filling type can also improve marking efficiency. 1. Bow-shape filling and back-shape filling: Mainly affected by the corner delay, it can reduce the light-on delay, light-off delay, and end delay.
2. Two-way filling, one-way filling: Mainly affected by the light-on delay and light-off delay, it can reduce the corner delay and end delay. But at the same time, it should also be noted that for thick graphics, the font is less affected by the delay, and the delay can be appropriately reduced; for thin graphics, the font is greatly affected by the delay, and the delay can be increased appropriately. Fifth, other channels.
tick“evenly spaced fill line”. Ultraviolet laser marking machine can remove thick graphics and fonts“enable profile”and“take a walk”. If the effect allows, it can be increased“advanced”of“jump speed”, reduce“jump delay”.
Marking a large range of graphics, properly divided into several parts to fill, can effectively reduce the jump time and improve the marking efficiency. Just set the shape of the workpiece in advance, and only switch the setting to correspond to the focal length of different product orientations, the marking orientation and shape changes, and it can be completed without moving the workpiece or laser marking multiple times. Deep engraving: Traditional 2D marking has inherent shortcomings in deep engraving on the surface of objects. As the laser focus moves up during the engraving process, the laser energy acting on the actual surface of the object will drop sharply, seriously affecting the effect and efficiency of deep engraving. For the traditional deep engraving method, the electric method moves the lifting table to a certain height at regular intervals during the engraving process to ensure that the laser surface is well focused.
Color engraving and engraving: On the same plane, black and white marking, even multi-color marking can be achieved, and the effect is more abundant. For general metal surface blackening, such as anodized aluminum, a higher frequency pulse is usually used under appropriate energy. Marking under certain defocus conditions, the defocus distance significantly affects the energy distribution and color effect of the laser on the surface of the material IC automatic laser marking machine. For general 2D marking users, even if there is no need for curved surface marking, etc. High-end features, 3D laser marking machine can carry out multi-gray and multi-color effect plane processing is also very meaningful. Concave-convex surface marking: In the current traditional 2D marking mode, the workpiece must be placed on the same plane, and the processing surface must also be on the same plane to complete one-time marking. Using the characteristics of 3D laser marking machine, It can complete the marking of one-time molding when the workpiece has a height difference. Even on an inclined slope, it can maintain the consistency of processing, so that the processing content will not be deformed, and there will be no color difference, which greatly facilitates the three-dimensional structure. The carving of the workpiece reduces the process of the process and improves the efficiency of marking. Arbitrary surface marking: 3D laser marking machines can quickly change the laser focal length and laser beam position, so it is possible to mark curved surfaces that could not be achieved in 2D before.
After using 3D, the cylindrical marking within a certain arc can be completed at one time, which greatly improves the processing efficiency. Moreover, in real life, the appearance of many parts is irregular, and the height of some parts is quite different. For 2D printing Marking processing is really powerless. At this moment, the advantages of 3D marking will become more obvious. Zhuhai Correct Pack is a well-known laser equipment manufacturer in China.
