Problems solved by technology

[0003] But the existing laser deburring method still has deficiencies
First of all, this method scans and cuts the burrs along the edge of the workpiece according to the size of the workpiece. Since there is a certain error between the actual workpiece and its standard size, the laser will inevitably scan the workpiece itself, causing the workpiece to be affected by the heat of the laser and affect its surface quality; Secondly, since burrs are usually intermittently attached to the edge of the workpiece, scanning according to the size of the workpiece will not only scan the parts of the workpiece with burrs, but also scan the parts without burrs, which will affect the deburring efficiency

Embodiment Construction

[0041] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0042] The laser deburring system of the present invention comprises a laser processing device 1, an image acquisition and processing device 2, such as figure 1 As shown, the laser processing device 1 includes an operating platform 3 that can move along the X and Y directions.

[0043] The image acquisition and processing device 2 may be a CCD image acquisition and processing device or a CMOS image acquisition and processing device. The CCD image acquisition and processing device is used in this embodiment, and the collected images are clearer. The image acquisition and processing device 2 is equipped with a dome light source 4 and a backlight source 5 to ensure that images of the workpiece can be captured more clearly.

[0044] The image acquisition and processing device 2 collects images of workpieces and performs image processing. It is internally...

Abstract

The invention relates to the technical field of laser machining and provides a laser deburring method which comprises the following steps of: acquiring an actual outline of a workpiece and a burr outline through a workpiece image, determining a start point coordinate and an end point coordinate according to a distance between the actual outline of the workpiece and the burr outline, and cutting the burr according to the start point coordinate and the end point coordinate of the burr of the workpiece. With the adoption of the method, a part with the burr is only required to be cut, and deburring treatment is not required to be performed on the whole outline of an object, so that the deburring efficiency is improved. Simultaneously, the workpiece quality is ensured since parts without the burrs on the workpiece are not influenced by laser heat.

Description

technical field [0001] The invention relates to the technical field of laser processing, in particular to a system and method for laser deburring. Background technique [0002] When the workpiece is processed by milling, casting and other processes, burrs will be formed on the edge of the workpiece, which needs to be deburred. At present, the commonly used deburring methods mainly include electrochemical, ultrasonic and laser deburring methods. The electrochemical deburring method is more corrosive to the workpiece and will pollute the environment; and the ultrasonic deburring method is due to its uneven impact force. It will lead to incomplete deburring; the laser deburring method uses the heat of the laser to dissolve and gasify the burrs around the workpiece, so as to achieve the purpose of deburring. Compared with the electrochemical method, this method not only causes less damage to the workpiece, but also It is more environmentally friendly and can remove burrs more t...
