Full-automatic laser cutting system and control method

Abstract

The invention belongs to the technical field of laser cutting and discloses a full-automatic laser cutting system and a control method. A rotating module carries out space rotating on an article to becut. A laser transmitting module transmits laser. A center control module extracts sample data in a database of the article to be cut. A setting module sets a pattern of the article to be cut. An angle adjusting module adjusts the angle between a laser light path and the article to be cut after a modulation module is utilized for carrying out modulation. A cutting module carries out cutting. According to the system and the control method, the service life of the motor is prolonged, and the production cost is reduced; meanwhile, the cutting module controls a laser head to move according to thecutting depth curve so as to cut the article to be cut, and the cutting depth of the article to be cut adapts to the cutting depth curve; and accordingly, a laser cutting machine adopting the cuttingmethod can machine grooves with equal groove depths, and thus adaptability of the laser cutting machine is good.

Description

technical field [0001] The invention belongs to the technical field of laser cutting, and in particular relates to a fully automatic laser cutting system and a control method. 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. In the field of automobile manufacturing, the cutting technology of space curves such as car roof windows has been widely used. Volkswagen of Germany uses a laser with a power of 500W to cut complex-shaped body sheets and various curved parts. In the field of aerospace, laser cutting technology is mainly used for cutting special aerospace materials, s...

Problems solved by technology

Most of them are also based on simple control steps, and the data accuracy for cutting control of precision components is poor

[0008] The higher grid density of the existing technology greatly increases the time for establishing the database, and also causes difficulties for the later database update, which makes the spatial positioning method have strong limitations in practical applications
