Problems solved by technology

In the actual data production process, most of the customer's files have corners. When there are many corners in the shape, it will take a very long time to manually add drilling holes, and it is easy to cause problems such as artificial missing additions that lead to unqualified corners.

Embodiment

[0058] When there is an arc on the PCB shape, such as figure 1 As mentioned above, it shows a PCB outline drawing with an arc 1, through the graphic design software genesis2000, the starting point coordinates, end point coordinates, and the center point 2 of the circle formed by each arc can be captured. Coordinates, as shown in the figure below, to obtain the coordinates of the arc center, first ask for the azimuth angles of the arc starting point and arc end point coordinates, then obtain the azimuth angles of the arc center coordinates, obtain the arc center coordinates according to the trigonometric function, and then press Find The coordinates of the arc are interrupted.

[0059] When there is a corner on the shape of the PCB, first enter the degree of the corner, and you need to add the corner drilling, usually 180 degrees. With the help of genesis2000 software, after reading the shape data, with the help of the functions of the software itself, such as image 3As show...

Abstract

The invention discloses a PCB outline machining method and device and a readable storage medium. The method comprises the following steps of S1, detecting whether an arc or a corner exists on the outline of a PCB or not, when the arc exists on the outline of the PCB, executing a step S2, and when the corner exists on the outline of the PCB, executing a step S3; S2, making a milling tape file according to the outline of the PCB, and breaking the arc in the milling tape file; and S3, making a drilling file, and adding a drilling hole at the corner of the outline of the PCB. According to the method, by detecting whether the arc and the corner exist on the outline or not, the arc is automatically broken, the drilling hole is automatically added at the corner, manual intervention can be directly reduced, the error probability is reduced, the working efficiency is improved, the operation time of workers is shortened, the labor cost is greatly saved, and the percent of pass of the outlines isimproved.

Description

technical field [0001] The invention relates to the technical field of PCB production, in particular to a PCB shape processing method, device and readable storage medium. Background technique [0002] In the process of PCB production and processing, shape making is an important part. There are various shapes of PCB, some regular and some irregular, so different machines (such as PCB gong board machine and drilling machine) need to be used. [0003] When using a PCB gong board machine for gong boards, it is necessary to make shape milling tape data. When an arc occurs, if the shape milling tape of the arc position is completed at one time, it is easy to cause a mismatch between the milling tape and the arc. In order to avoid this situation, it is necessary to interrupt the arc in the profile milling tape, so that the milling tape has a pause at the arc position. For orders with complex shapes, there may be hundreds of arcs. It takes a long time for engineers to manually inte...
