The invention relates to the technical field of
industrial Internet of Things, edge calculation, silk-screen and the like, and provides a substrate silk-
screen method and equipment based on an intelligent silk-screen unit, and the method comprises the steps: configuring a feeding mechanism, a dust removal mechanism, a pre-printing alignment mechanism and a printing mechanism which are connected in sequence, and establishing an
industrial Internet of Things information sensing layer and an edge gateway which are in two-way communication with the feeding mechanism, the dust removal mechanism, the pre-printing alignment mechanism and the printing mechanism. Order and formula data are received through a gateway, multi-source sensing
point location real-
time data are fused, a
production model with a unified time reference and batch identification is constructed, and process parameters are dynamically issued. And during feeding, the model and the warping degree of the substrate are automatically recognized, and dust removal parameters are synchronously adjusted. In the printing process, screen tension, scraper stress, motor current and
printing ink rheological property are monitored in real time and fused to obtain a
printing ink comprehensive rheological characteristic value, scraper parameters and an ink
return time sequence are cooperatively regulated according to the
printing ink comprehensive rheological characteristic value, and a printing quality estimated value is output. According to the method, collaborative optimization and quality
estimation of the whole printing process are achieved, and the production adaptability and consistency of product printing are improved.
