Fully-automatic bookbinding linkage line of paperboard book and bookbinding method thereof

The invention relates to a fully-automatic bookbinding linkage line of a paperboard book and a bookbinding method thereof. The fully-automatic bookbinding linkage line comprises a controller, and an inner sheet conveying system, a mounting system and a cover applying system which are sequentially connected through a conveying line, and further comprises a plurality of numerical control coating systems and pressing mechanisms, wherein the plurality of numerical control coating systems and pressing mechanisms are respectively arranged in the mounting system and the cover applying system, and the controller is connected with all systems through control devices arranged in the all systems. According to the fully-automatic bookbinding linkage line, the whole bookbinding linkage line is controlled through a controller terminal so that fully-automatic integrated production is realized, the speed can reach 12000 sheets per hour, and the daily capacity can reach 96000 sheets, with 3000-5000 finished books per hour, and thus the work efficiency is greatly improved.
