The invention provides a rotary lamination packaging system and a lamination treatment method, and overcomes the technical shortcomings of large occupied area and low working efficiency of a solar cell component packaging system in the prior art. The technical scheme includes that the system comprises at least one lamination subsystem, the lamination subsystems comprise rotary lamination furnace devices, rotary cooling furnace devices and first conveying mechanisms, the rotary lamination furnace devices comprise first rotation mechanisms and a plurality of lamination sub-furnaces arranged on the first rotation mechanisms, the rotary cooling furnace devices comprise second rotation mechanisms and a plurality of cooling sub-furnaces arranged on the second rotation mechanisms, and the first conveying mechanisms are used for conveying lamination objects in the lamination sub-furnaces into the cooling sub-furnaces. According to the system, production space and device investment costs are greatly saved, production time is saved, and production efficiency is improved.
