The invention discloses a separating device, comprising a base, a feeding carrier plate, a press plate, a transmission mechanism, an ejector pin module and a first driving module, wherein first through holes are formed in the feeding carrier plate, and a transmission object is placed on the feeding carrier plate; second through holes are formed in the press plate; the transmission mechanism is matched with the transmission object in a separated state so as to drive the transmission object to move relatively to the feeding carrier plate; the ejector pin module can be used for jacking a separating part in a separated state so as to enable the separating part to be separated from a carrier; the first driving module can be used for driving the ejector pin module to move up and down. Accordingto the separating device provided by the invention, the transmission mechanism can drive the transmission object on the feeding carrier plate to move left and right, and the first driving module can drive the ejector pin module to jack the separating part so as to enable the separating part to be separated from the carrier, so that the automatic separation between the separating part and the carrier can be realized, the cyclic operation of the separating device can be realized, and the working efficiency is further increased. The separating device is simple to operate, can realize automatic operation, and has very high practicality.
