Positioning identification method, positioning identification system and processing system of PCB (Printed Circuit Board)

The invention provides a PCB positioning identification method, a positioning identification system and a processing system, and relates to the technical field of PCB production. The PCB positioning identification method comprises the following steps: acquiring a picture of a to-be-positioned PCB shot by a camera, and acquiring first data information; processing the picture and acquiring second data information; judging whether the first data information and the second data information are stored in pre-stored board type data of the database or not; if at least one of the first data information and the second data information is not stored in the database, storing the data information which is not stored in the first data information and the second data information in the database, according to the first data information and the second data information, newly-added version data are established in a database; if the first data information and the second data information are stored in the database, positioning
