The invention provides a pneumatic separation unlocking device and system. The unlocking device comprises a shell, a core seat, a core shaft, a locking mechanism and a pneumatic separation thrust mechanism. The core seat is fixedly connected with a separated part, and the core seat is arranged in the shell and fixedly connected with the shell; the mandrel is inserted into the mandrel seat, and one end of the mandrel outside the mandrel seat is fixedly connected with the separating part; the locking mechanism is arranged in the shell, and the locking mechanism is clamped into the core seat and the core shaft, so that the core shaft and the core seat are connected in a locking manner; the pneumatic separation thrust mechanism is connected into the shell and connected to the top end of the mandrel in an abutting mode. And the pneumatic separation thrust mechanism is used for pushing the core shaft to move out of the core seat so as to unlock the locking mechanism. The unlocking device is simple in structure and short in unlocking and separating time, and the multiple unlocking devices can achieve good separating consistency and synchronism.
