Plate laser cutting machine, control method thereof, and computer

Abstract

The invention belongs to the technical field of laser cutting, and discloses a plate laser cutting machine, a control method thereof, and a computer. Position image data of a to-be-cut plate are collected; image position infotom obtaining is conducted, specifically, edge information of each sequence image is obtained, all the sequence images are divided into identical areas, and aggregation position information is obtained through an immune genetic method by adopting an adaptive vaccine extraction mechanism; the position information is subjected to three-dimensional reconstruction of a markedobject; focal length adjusting is automatically controlled through a central processing module according to the three-dimensional reconstructed mark; and the cutting track of the to-be-cut plate is covered with a heat absorbing layer, and then the plate is subjected to laser cutting. According to the plate laser cutting machine, the control method thereof, and the computer, through the immune genetic method, the accuracy rate is increased by nearly 10% compared with that of the prior art, the product pass rate is increased by nearly 15%, and the guarantee is provided for enterprise benefits; and meanwhile, the control method can be popularized to other fine chemical industry or other precision control production fields.

Description

technical field [0001] The invention belongs to the technical field of laser cutting, and in particular relates to a plate laser cutting machine, a control method and a computer. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Laser cutting uses a high-power-density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature, and evaporates to form holes. As the beam moves to the material, the holes continuously form a narrow (such as about 0.1mm) slit. , to complete the cutting of the material. Most laser cutting machines are controlled by CNC programs or made into cutting robots. As a precision processing method, laser cutting can cut almost all materials, including two-dimensional cutting or three-dimensional cutting of thin metal plates. [0004] In the field of automobile manufacturing, the cutting technology of space curves such as c...

Problems solved by technology

[0006] The laser adjustment effect of the existing plate laser cutting machine is poor, resulting in poor cutting quality; at the same time, cracks and other defects are prone to occur during cutting, which in turn affects the quality of plate products

[0007] In the prior art, among the image processing methods, the commonly used non-negative matrix processing method and binarization method all have poor data accuracy in the image data processing of different shapes of the plates to be cut, which affects the quality of the product. The existing Technology does not incorporate immunogenetic methods for accurate processing
