1. Relative density of laser marking: In the same width, same light spot, and same deep layer conditions, the higher the relative density of the marking base, the slower the matching laser marking rate, because the relative density immediately increases the total area of ​​the marking base .
 
  2. Laser marking width: The laser marking rate of large-format laser marking is slower than that of small-width laser marking, due to the increase of the total offset area of ​​the scanning galvanometer for large-scale laser marking.
 
3. Laser marking deep layer: According to the requirements, if you need to increase the marking of the deep layer, the main parameters of the fiber laser marking machine must be adjusted, and the main parameters such as the output power and current of the fiber laser marking machine must be expanded. Hazardous laser marking rate.
 
   Laser spot size: the larger the spot, the faster the laser marking rate.
 
  Adjustment method:
 
   One or four refills to choose which suits;
 
  1. Double filling: laser marking is highly efficient and easy to use.
 
  2. Rectangular filling: It can only be applied when laser marking fine graphics and font styles. High efficiency is similar to bow filling.
 
  3. Unilateral refilling: Laser marking is highly efficient and slow, and it is rarely used in specific production and processing.
 
  4. Bow-shaped filling: Laser marking is highly efficient, and sometimes problems of alignment and unevenness may occur. When laser marking fine graphics and font styles, the problems are not easy to appear, so bow-shaped filling is preferred.
 
   2. How to improve the efficiency of laser marking in the production and processing of goods:
 
   1. Choose a good high-speed scanning galvanometer;
 
Under normal conditions, the speed source of the scanning galvanometer scanner can achieve 3000mm/s, but you don’t know that a better high-speed scanning galvanometer can tens of thousands of scanners per second (you can understand the meaning of more zero and less zero. ). In addition, when the general scanning galvanometer laser is used to mark subtle graphics or font styles, it is very prone to deformation, so you must reduce the scanner speed to ensure the actual effect.
 
  2, suitable field lens;
 
  The larger the focal length of the field lens lens, the larger the focal spot light spot. Under the same spot coincidence rate, the filling line interval can be enlarged and the laser marking efficiency can be improved. Remark name: The larger the field lens, the lower the power, so it is necessary to expand the refill line interval while ensuring sufficient laser marking kinetic energy.
 
   Three, set court time appropriately;
 
  Different types of refills are harmed by different times, so reducing the time irrelevant to the types of refills can improve the efficiency of laser marking.
 
  1. Bow-shaped top-up, back-shaped top-up: The key is affected by corner court time, which can reduce switch court time, off light court time, and end court time;
 
  2, double recharge, unilateral recharge: the key is affected by the switch time and the light time, which can reduce the corner time and the end time;
 
   But also pay attention to the fact that thick graphics and font styles are less harmful to court time and can moderately reduce court time. The fine graphics and font styles are very harmful to the court and can moderately increase the delay.
 
   The primary conditions for the production and processing of goods are the relative density of laser marking, laser marking width, laser marking depth and laser spot size under marking conditions.
 
   1. The deficiency of relative density of laser marking:
 
   In the same width, same light spot, and the same deep layer, the higher the relative density of the marking base, the slower the matching laser marking rate, because the relative density immediately increases the total area of ​​the marking base;
 
  2. Insufficiency of laser marking width:
 
   The laser marking rate of a large-scale format is slower than that of a small-format laser, because the total offset area of ​​the large-scale laser marking scanning galvanometer increases;
 
  3. Insufficiency of laser marking deep layer:
 
According to the requirements, if the laser marking deep layer must be emphasized, and the main parameters of the laser marking machine must be adjusted, the output power of the fiber laser marking machine can be expanded, and there are also main parameters such as current, which will harm the marking bottom. rate;
