The present invention relates to an outer ring coupling device which comprises: a main frame coupled with a robot arm; a plurality of support units coupled with the main frame to be radially slidable wherein the support units support an outer ring coupled with an outer circumference of a coil; a sliding unit for sliding the support units; and a pressurizing unit installed on at least one of the support units wherein the pressurizing unit pressurizes the outer circumference of the outer ring toward the coil to couple the outer ring with the coil. An outer ring coupling unit according to the present invention couples the outer ring with the coil by the pressurizing unit to prevent the outer ring from the coil during movement of the coil, thereby reducing a defect rate. |
