A kind of laser drilling control method

Abstract

The invention provides a laser drilling control method, which belongs to the field of laser processing. The present invention comprises the following steps: setting the helical graph file; adjusting the laser and transporting the product to be processed to the processing position; setting the starting point of the 3D galvanometer: the 3D galvanometer sets the starting point of the laser focus on the lower surface of the product to be processed; The XY axis of the galvanometer is linked with the Z axis, and the laser beam is adjusted to drill holes from the lower surface of the glass to the upper surface along the set continuous helix; after the helix of the set number of layers is completed, the laser is turned off, and the XY axis of the galvanometer is aligned with the Z axis. The axes return to their initial positions. The beneficial effect of the invention is that the processing efficiency is improved, there is no cutting edge for turning on and off the laser from bottom to top, and the cross section is very smooth.

Description

technical field [0001] The invention relates to a display screen structure, in particular to a laser drilling control method. Background technique [0002] With the development of production and transportation fields toward higher and higher speeds and higher precision, many fields have higher requirements for the speed and accuracy of conveying materials. [0003] Especially in the rapidly developing machinery and equipment industry and the subdivided fields of the logistics industry, the desire for high-precision, high-speed, and high-acceleration transportation is flocking. [0004] At present, the mainstream product in the market is low-iron toughened suede glass, with a thickness of 3.2mm. In the wavelength range corresponding to the solar cell spectrum (320-1100nm), the light transmittance can reach more than 91%, and it has a high performance for infrared light greater than 1200nm. Reflectivity. The suede is made by pressing a special pyramid-shaped pattern on the g...

AI Technical Summary

Problems solved by technology

[0016] A. There will be traces of the knife on the edge of the step on each floor. This kind of trace will easily make it difficult to cut or form a notch, which will not only cause the anchorage to fail to fall off naturally, but also affect the processing of the subsequent process;

[0017] B. Since the 3D vibrating mirror is used, the movement efficiency and processing mode will be faster than the existing technology 1 and 2, but because the Z and XY axes of the vibrating mirror are not linked, the processing efficiency still cannot reach the best ideal state
