Problems solved by technology

[0010] This method mainly relies on the arc fitting function of software such as Genesis. Although it can better meet the error requirements, the fitting completion rate is not high, and it often occurs that the line group is not fitted or the line group that has been fitted still contains In the case of short line segments, and the arc equalization with a central angle greater than 180° must rely entirely on manual work
When the length of the line segment or arc is too short, it may cause flying knife phenomenon, and the arc with too large central angle may cause deformation of the circuit board when drilling the gong. Therefore, the gong tape file processed by Genesis software still needs to be processed. Gong tape engineers spend a lot of time manually processing the wire groups with poor fitting effect, which seriously affects the efficiency of gong tape production

Abstract

The present invention provides a method and a device for generating circular arc gongs on circuit boards. The scheme adopts three different methods for judging tangent points of circular arcs and integrates the curve line groups for complex curves composed of short line segment groups on circuit boards. Three methods are used to accurately identify the tangent point, so as to realize the segmentation of complex line groups, and have a good segmentation effect for various complex line groups, the number of arcs after fitting and the remaining short lines Fewer sections, closer to the actual needs of the project.

Description

technical field [0001] The invention relates to the field of PCB, in particular to a method and a device for generating a circular arc gong of a circuit board. Background technique [0002] The gong belt refers to the program used for the gong-type machine tool gong board. The production of the gong belt is a very important part in the production of the circuit board. During the production of the gong belt, it is necessary to convert the single file (gerber-gko file) downloaded by the customer into the gong machine. Recognized project file. [0003] In order to meet the needs of various actual functions or product aesthetics, the gongs of the circuit board often contain various curves, but the path of the gong machine can only be a straight line or a circular arc. In the original gerber-gko file, a set of short line segments connected end-to-end is often used to replace the curve. However, if the gong machine directly produces the gong belt according to the short line segme...
