A method and system for real-time repairing of PCB circuit boards based on 3D vision

Abstract

The invention discloses a method and system for real-time repairing of PCB circuit boards based on 3D vision, wherein the method for real-time repairing of PCB circuit boards includes: A. obtaining standard three-dimensional imaging information of standard circuit boards; B. obtaining circuit boards through three-dimensional imaging components C. Compare the standard 3D imaging information with the primary 3D imaging information, and determine whether laser repair is required for the circuit board according to the comparison result. A real-time PCB circuit board repair method based on 3D vision proposed in this technical solution can realize synchronous processing of 3D imaging and laser repair, greatly improving the repair efficiency of circuit lines, and then proposes a PCB circuit board based on 3D vision The board real-time repair system has high precision, which is beneficial to realize the synchronous processing of 3D imaging and laser repair, short circuit repair and open circuit repair, as well as realize the synchronous repair of circuit board open circuit and short circuit. It has simple structure, reliable performance and easy operation.

Description

technical field [0001] The present invention relates to the technical field of PCB circuit board repairing, in particular to a method and system for real-time repairing of PCB circuit boards based on 3D vision. Background technique [0002] PCB (Printed Circuit Board) is called a printed circuit board, also known as a printed circuit board. It is an important electronic component, a support for electronic components, and a carrier for electrical interconnection of electronic components. Because it is made using electronic printing, it is called a "printed" circuit board. Almost every kind of electronic equipment, ranging from electronic watches and calculators to computers, communication electronic equipment, and military weapon systems, as long as there are electronic components such as integrated circuits, in order to make the electrical interconnection between various components, printed circuit boards must be used. circuit board. In the process of circuit board product...

Problems solved by technology

Specifically, the Chinese invention patent with the publication number CN1960602A proposes a device and method for automatically detecting, repairing and automatically marking printed circuit boards. However, in its repair method, visual imaging and laser repair need to be carried out separately, and synchronous processing cannot be achieved, resulting in that the repair efficiency of the circuit board cannot be effectively improved.
