a dust extraction device

Abstract

The invention discloses a dust extraction device, which comprises: a main body with a curved flow path, the outlet of the curved flow path communicates with a dust suction power source; a first auxiliary mechanism for providing a first auxiliary airflow, the first auxiliary mechanism A first blowing port of the auxiliary air flow is located above the entrance of the curved flow channel. The dust extraction device of the present invention adds the first auxiliary air flow, the outlet of which is located above the inlet of the main curved flow channel for dust extraction, the first auxiliary air flow is positive pressure, and the blown air flow combined with the negative pressure of the curved flow channel further improves the dust on the surface of the workpiece Odor removal efficiency. It solves the existing dust extraction structure used in the field of laser processing. Most of them use a single dust extraction flow channel, and the dust extraction effect is not good. By directly increasing the power of the dust extraction fan, even if the dust extraction effect is improved, it is not possible. Avoid the problems that affect the quality of laser processing.

Description

technical field [0001] The invention relates to the technical field of laser processing equipment, and more particularly, to a dust extraction device for laser processing. Background technique [0002] With the rapid development of laser processing technology, laser processing is widely used in the panel industry. Laser processing uses a high-energy-density laser beam to heat the workpiece, causing the temperature to rise rapidly and melt the material. [0003] Laser cutting is a common and widely used method in laser processing. With the widespread use of laser cutting in various fields, laser cutting has been used in the cutting of various materials. With the development of industry, especially the miniaturization of electronic products, the precision cutting of processed materials has gradually become the main development direction of laser cutting. . During the process of laser cutting materials, a large amount of smoke, peculiar smell and a small amount of dust will b...

AI Technical Summary

Problems solved by technology

During the process of laser cutting materials, a large amount of smoke, peculiar smell and a small amount of dust will be generated. If they adhere to the surface of the laser lens for a long time, the service life of the laser processing machine will be affected. In severe cases, it will hinder the normal operation of the machine and reduce production efficiency. Certain economic losses, and these inhalation of the human body will cause great harm to the human body

[0004] Most of the existing dust extraction structures used in the field of laser processing use a single dust extraction flow channel, and the dust extraction effect is not good. If the power of the dust extraction fan is directly increased, although the dust extraction effect is improved, it is inevitable Influence on the quality of laser processing
