Abstract

The embodiment of the invention discloses a method and apparatus for realizing PCBA board detection. The method comprises: location information of a to-be-detected PCBA board is obtained; when the to-be-detected PCBA board moves to a preset position, a test file is obtained, wherein the test includes a feature value of the to-be-detected PCBA board; on the basis of the feature value, feature matching is carried out on the to-be-detected PCBA board and the test file and the type of the to-be-detected PCBA board is determined; and according to the test file matching the type of the to-be-detected PCBA board, an element of the to-be-detected PCBA board is detected and a detection result is fed back. According to the method disclosed by the invention, feature matching is carried out on the to-be-detected PCBA board and the test file to determine the type of the to-be-detected PCBA board and the to-be-detected PCBA board is detected based on the test file corresponding to the type of the to-be-detected PCBA board. On the basis of determination of the type of the to-be-detected PCBA board, simultaneous detection of production at the same production line of several kings of PCBA boards is realized and the product applicability is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of circuit board manufacturing, and in particular to a method and device for realizing PCBA board detection. Background technique [0002] With the development of the electronic industry, a large number of programmable chips are produced. Printed Circuit Board Assembly (PCBA), that is, the PCB empty board is mounted on the surface mount technology, and then through the entire process of the dual in-line packaging technology plug-in. At present, the online inspection method of PCBA only supports one board type detection at a time. If boards of multiple board types are produced on a production line at the same time, only one of the board types can be detected, and other board types will prompt a large number of false positives or directly Skip no detection. When a production line is shared by multiple plate types, it is impossible to detect all the plate types passing through the unified prod...
