When a laser marking machine is used, the problem of correctly adjusting the focal plane is involved. When equipment manufacturers are used for training and sample adjustment in equipment installation, importance of focal length can be emphasized, and the correct focal length surface can be missed due to the fact that the laser focal length surface is too high or too low, and laser carving on the correct focal length surface is a key factor for enabling a laser marking machine to normally play the performance of the laser marking machine.
As shown in fig. 7 of the drawings, the light is converged into a point from the center of the convex lens, the length between the convex lens and the convex lens is the focal length, and the converging position is the focal point; for laser marking, the focal path is often not found because a different product is replaced, because the focal length of any convex lens is fixed. The laser can reach the maximum power and effect only at the focal position (as shown in fig. 7 of the specification), so when the thickness of the marking object B changes, the whole convex lens also needs to move relatively, and the focal point is always on the surface of the B.
In the conventional method, a lot of equipment operators grasp how to quickly and correctly debug the focal length of the laser marking equipment, in the normal case, after the focal length is found, a ruler is used for measuring the distance from a lower vibration lens to the surface of an article, then the distance is used as a fixed value, after the article is replaced, only the ruler is needed to be taken out, so that the height from the vibration mirror to the surface of the article reaches the value again, and then an adjusting column is rotated to adjust the height of the vibration mirror to a proper position.
However, for some layered articles, the positioning of the focal length through the ruler is difficult, firstly, the perpendicularity of the ruler is difficult to control, so that the measurement result is very accurate every time, secondly, the layered articles or the articles with the uneven self are difficult to place when the ruler is placed, and the ruler is also bent due to different forces of different people during measurement, so that the result is very inaccurate and time is wasted.
Based on the problems, the utility model provides the laser marking machine focusing device which is only required to be assembled on the vibrating mirror of the laser marking machine, and when the device is used, the focal length of the laser marking machine can be confirmed by observing whether laser emission points are overlapped or not, so that the focal length of the laser marking machine can be conveniently and quickly adjusted, meanwhile, for uneven products, only the position of the laser marking machine, which is required to mark on the products, is required to be confirmed, the products are placed at the position of the laser intersection point, the focal length adjustment by repeatedly using a ruler is not required, and the device is time-saving, labor-saving and accurate.
