A method, device and storage medium for automatic adjustment of pcb silk screen printing

Abstract

The invention provides a PCB silk-screen automatic adjustment method and device and a storage medium. The method comprises the steps of acquiring component images and an original silk screen image, uniformly setting all silk screen texts in the original silk screen image to be in an initial font size, gradually calculating the sizes of all component sub-images on the component images according tocomponent packaging information, calculating the sizes of the silk screen texts according to the initial font sizes, gradually judging whether the obtained silk screen text sizes are larger than the sizes of the corresponding component sub-images or not, and if the obtained silk screen text sizes are larger than the sizes of the corresponding component sub-images, adjusting the font sizes of the silk screen texts until the font sizes of the silk screen texts are completely adjusted. By means of the PCB silk-screen automatic adjustment method and device and the storage medium, the silk screen texts can be set as the initial fonts, then the corresponding silk screen texts are gradually modified to be in suitable sizes according to the sizes of the components, automatic silk screen adjustmentcan be carried out, the sizes of the components cannot be exceeded, manual adjustment is not needed, and the efficiency is greatly improved.

Description

technical field [0001] The invention mainly relates to the technical field of PCB silk screen typesetting, and in particular to a PCB silk screen automatic adjustment method, device and storage medium. Background technique [0002] PCB board silk screen text, its function is to facilitate the installation and maintenance of the circuit, etc., to print the required logo patterns and text codes on the upper and lower surfaces of the PCB board, such as component labels and nominal values, component outline shapes and Manufacturer's logo, production date, etc. From the perspective of electrical characteristics, no silk screen information has no effect on circuit performance. The silk screen on the PCB is mainly for people to see, and it serves as an indicator for production, assembly and maintenance. Therefore, silk screen layout has certain requirements and specifications, but The current screen printing typesetting technology causes confusion in the screen printing display, m...

Problems solved by technology

From the perspective of electrical characteristics, no silk screen information has no effect on circuit performance. The silk screen on the PCB is mainly for people to see, and it serves as an indicator for production, assembly and maintenance. Therefore, silk screen layout has certain requirements and specifications, but The current screen printing typesetting technology causes confusion in the screen printing display, making it difficult to read or cause ambiguity

[0003] At present, the usual practice in the industry is to manually adjust, or to use simple tools to place the silk screen at the origin of the device. This method is inefficient, cumbersome, and cannot achieve the desired effect.
