Intelligent laser cutting system provided with master-slave camera and cutting method thereof

Abstract

The invention provides an intelligent laser cutting system provided with a master-slave camera and a cutting method thereof. The intelligent laser cutting system provided with the master-slave camera comprises a worktable, a small head stock, a local slave camera and a laser head, a global master camera, a monitoring terminal, a main controller and a driving motor, wherein the worktable is positioned at the bottom; the small head stock is arranged above the worktable; the local slave camera and the laser head are fixedly arranged with the small head stock; the global master camera is hung on the top; the monitoring terminal is used for monitoring images of the global master camera and the local slave camera; the main controller is electrically connected with the global master camera; the driving motor is controlled by the main controller and is connected with the worktable and the small head stock; a lens visual field of the global master camera comprises the entire worktable; the driving motor drives the small head stock to move; and the local slave camera moves synchronously along with the small head stock and performs local image acquisition on the worktable. High-efficiency and high-accuracy laser cutting processing can be performed on various applicable objects without depending on the accuracy of the main controller of a laser cutting machine and a mechanism.

Description

technical field [0001] The invention relates to an intelligent numerical control device adopting machine vision, in particular to an intelligent laser cutting system adopting master-slave correlation and a laser cutting method using the same. Background technique [0002] In the traditional laser cutting machine based on the main controller, the coordinate point (Mark point) of the design center mark point that needs to be processed is pre-recorded in the processing program (NG code), and then the main controller interprets this code program , to realize the positioning motion control, and realize the step of irradiating the laser synchronously. (See patent document Japanese Patent Laid-Open No. 2000-343260). With the rapid development of the miniaturization of objects to be cut, the demand for fine positioning technology is getting higher and higher. In view of the fact that the effective range of laser cutting of tiny processing objects is very small, the deviation of th...

Problems solved by technology

However, the pixel and processing speed of the camera will affect the accuracy of the feedback position, especially at the far end of the optical axis center of the camera lens, the distortion phenomenon is more serious, and the image processing result will be greatly affected

Of course, improving the camera resolution and preprocessing the camera lens distortion is a solution, but the former costs a lot, and the latter has cumbersome processing steps, which is not the optimal processing method.
