Abstract: An apparatus for mounting an O-ring to a work piece, including: a plurality of picking components operable to move away from each other to contact and expand the O-ring to pick the O-ring or to move towards each other to release the O-ring; and a guiding component including a frustum portion arranged coaxially with a groove of the work piece, a large end face of the frustum portion arranged adjacent to an end surface of the work piece on which the groove is formed, wherein a diameter of the large end face is substantially same as an inner diameter of the groove, wherein the picking components are operable to release the O-ring onto a tapered surface of the frustum portion so that the O-ring is pushed into the groove along the tapered surface.
