An apparatus for bonding a release film for separating artificial stone from rubber mold, comprising: a body that includes at least one or more driving motors; a conveyor that is disposed on the body and conveys at least any one or more of a mold and a release film using power from the driving motor to a target position in a conveyance direction; a driving frame that comprises: a middle frame that is disposed over a target position in a conveyance direction of the conveyor to be vertically movable and is seated on the center of the top of the mold conveyed to the target position in the conveyance direction of the conveyor when moving downward; a four-directional moving frame including lateral moving frames that are composed of bars coupled to the left and right sides of the middle frame and are horizontally reciprocated left and right with the left and right sides of the middle frame, and longitudinal moving frames that are composed of bars coupled to the front and rear sides of the middle frame and are horizontally reciprocated back and forth with the front and rear sides of the middle frame; and an edge frame that extends outward from the middle frame to be vertically movable and is seated on the edge of the top of the mold conveyed to the target position in the conveyance direction of the conveyor when moving downward; and a suction-feeding roll that has: a plurality of suction grooves formed by boring the feeding roll so that a release film unrolled from an unwinding roll is adsorbed to the feeding roll when being conveyed; and one or more blade guide grooves formed in the longitudinal direction of the feeding roll so that a blade can be inserted therein and can cut the release film on the feeding roll. a body that includes at least one or more driving motors; a conveyor that is disposed on the body and conveys at least any one or more of a mold and a release film using power from the driving motor to a target position in a conveyance direction; a driving frame that comprises: a middle frame that is disposed over a target position in a conveyance direction of the conveyor to be vertically movable and is seated on the center of the top of the mold conveyed to the target position in the conveyance direction of the conveyor when moving downward; a four-directional moving frame including lateral moving frames that are composed of bars coupled to the left and right sides of the middle frame and are horizontally reciprocated left and right with the left and right sides of the middle frame, and longitudinal moving frames that are composed of bars coupled to the front and rear sides of the middle frame and are horizontally reciprocated back and forth with the front and rear sides of the middle frame; and an edge frame that extends outward from the middle frame to be vertically movable and is seated on the edge of the top of the mold conveyed to the target position in the conveyance direction of the conveyor when moving downward; and a suction-feeding roll that has: a plurality of suction grooves formed by boring the feeding roll so that a release film unrolled from an unwinding roll is adsorbed to the feeding roll when being conveyed; and one or more blade guide grooves formed in the longitudinal direction of the feeding roll so that a blade can be inserted therein and can cut the release film on the feeding roll.
