Abstract

The invention provides an optical reference point recognition method and system, a computer readable medium and equipment. The optical reference point recognition method comprises the steps of recognizing all pads and pad attribution information in graphic design data of a PCB to be recognized; reading recognition parameter configuration used for recognizing an optical reference point; according to the pad attribution information, the recognition parameter configuration and predetermined screening conditions in combination with a preset screening sequence of the predetermined screening conditions, judging all the pads one to one or parallelly to mark the optical reference point. The optical reference point for prejudgment can be provided for a client for reference, the client does not needto watch the board to manually look for the optical reference point by himself/herself, thus the steps of artificial participation in the SMT manufacturing procedure can be reduced, a key problem inautomated program manufacturing is solved, and technical support is provided for intelligent manufacturing in the electronic industry.

Description

technical field [0001] The invention belongs to the technical field of detection of PCB circuit boards, and relates to an identification method and system, in particular to an optical reference point identification method, system, computer-readable storage medium and equipment. Background technique [0002] Two or more optical reference points are designed on the PCB circuit board. The purpose is to locate the entire PCB board and facilitate the position identification of SMT equipment. Almost all SMT equipment such as screen printing machines, placement machines, optical inspection machines, etc. This benchmark will be used. [0003] At present, most of the procedures for making SMT equipment in the industry are manually moved to the position of the PCB optical reference point to find it; or engineers read the graphics in the design file through software and then designate this point as the optical reference point according to their own work experience. [0004] Intelligen...
