The invention provides an SMT patch
correction system linked with AOI and a method thereof. The SMT patch
correction system comprises a stokehole AOI detection module, a stokehole AOI detection module, a multi-dimensional sensing module, an intelligent
data center module, an AI decision optimization module and a
process simulation verification module. According to the method, the AOI detection data in front of and behind the furnace are fused through the intelligent
data center module, the mapping relation of
knowledge graph associated elements, the technology and offset data is constructed, a linkage
closed loop is formed, and offset
source tracing and full-process dynamic deviation correction are achieved; environmental parameters such as temperature, vibration and suction
nozzle pressure are collected in real time through the multi-dimensional sensing module, and the environmental parameters are standardized through an intelligent
data platform and then are included into correction logic of the AI decision optimization module, so that dynamic compensation of the influence of environmental factors on the mounting precision is realized; a
deep learning and
reinforcement learning cooperation strategy is adopted through the AI decision optimization module, parameters are dynamically optimized and corrected in combination with
thermal deformation simulation and other multi-source information of the
process simulation verification module, and the adaptability to different element types and production scenes is improved.
