The invention discloses a coupling dispensing system and a coupling dispensing method. An automatic coupling device of the coupling dispensing system is used for coupling a device to be coupled and anoptical fiber and comprises an adjusting mechanism and a clamping mechanism, wherein the clamping mechanism is arranged on the adjusting mechanism and comprises a sliding table and an elastic piece,one end of the elastic piece is connected with the sliding table, and the clamping mechanism is used for clamping the optical fiber; and the adjusting mechanism is used for adjusting the posture of the clamping mechanism so that the end face of the optical fiber is parallel to the end face of the device to be coupled. The automatic coupling device can enable the end face of the optical fiber to beparallel to the end face of a device to be coupled, and the consistency is good. The dispensing device of the coupling dispensing system is used for dispensing in the lateral direction on the end faces of the optical fiber and the device to be coupled, so that no glue is arranged on the light passing surfaces of the optical fiber and the device to be coupled, heat energy generated when light passes through the coupling glue is reduced, and the bearing power of the device can be improved.
