The invention discloses an RFID tag
production line defect real-time detection
system and compensation method based on
machine vision, and belongs to the technical field of intelligent manufacturing and
quality control. The
system comprises an
image acquisition module, a defect detection module, a compensation execution module and a
feedback control module, based on defect types and positions, a grading
compensation strategy is triggered, the grading
compensation strategy comprises real-time printing parameter adjustment,
laser accurate repair of a defect area or automatic rejection of a mechanical arm, and a process parameter
library is synchronously updated through an
industrial Internet of Things platform. The innovation points are as follows: (1) a multi-
modal defect data fusion method is provided, and the detection robustness under complex working conditions is improved; (2) a lightweight double-
branch detection network is designed, and the detection speed and precision are both considered; and (3) developing a compensation instruction cooperative
control algorithm to realize seamless connection between
defect repair and
production line rhythm. According to the scheme, the defect omission ratio can be reduced to 0.5% or below, the compensation
response time is shortened to be within 200 ms, and the
production line yield and the production efficiency are remarkably improved.
