The invention relates to a PCCP bell and spigot manufacturing device and process, in particular to a PCCP bell and spigot full-automatic production system and process. The PCCP bell and spigot full-automatic production system comprises a feeding part, an overturning and transferring part, a belt conveying line, a processor, a 90-degree overturning roller, a roller conveying line, a plate rolling machine and a welding machine. The overturning and transferring part capable of adsorbing, overturning and transferring plates onto the belt conveying line is mounted between the feeding part and the belt conveying line; and a visual identification instrument and a turn-over mechanism are sequentially installed between the head end and the tail end of the belt conveying line. Due to the implementation of the above technical scheme, the automation degree is high, and automatic sorting, automatic edge rolling and automatic welding can be achieved; the safety coefficient is improved, the manufacturing efficiency is greatly improved, the product quality is improved, only one person is needed for guarding in the whole process, and manpower is reduced; and the PCCP bell and spigot full-automatic production system and process are suitable for popularization and application.
