Title:
APPARATUS AND METHOD FOR MOUNTING O-RING AND ROBOT
Document Type and Number:
WIPO Patent Application WO/2021/056241
Kind Code:
A1
Abstract:
An apparatus (100) and method for mounting an O-ring (200) to a work piece (300). The apparatus (100) comprises a guiding component (101) comprising a frustum portion (1011) arranged coaxially with a groove (302) formed on an end surface (301) of the work piece (300) for receiving the O-ring (200), a large end face (1012) of the frustum portion (1011) arranged adjacent to the end surface (301); and an operation component (102) adapted to drive the guiding component (101) to rotate back and forth about a central axis (X) of the guiding component (101), wherein a diameter of the large end face (1012) is substantially same as an inner diameter of the O-ring (200) to allow the O-ring (200) surrounding and eccentric to the frustum portion (1011) to slide into the groove (302) with a rotation of the guiding component (101). With the diameter of the large end face (1012) of the frustum portion (1011) being substantially same as the inner diameter of the O-ring (200), a part of the O-ring (200) would lie on a bevel surface of the frustum portion (1011) after the O-ring (200) is dropped on the work piece. At this time, it is only necessary to reciprocally rotate the guiding component (101), and the O-ring (200) thereon would slid into the groove (302) against the frictional force, thereby realizing the automotive mounting of the O-ring (200) on an end surface of the work piece (300) with a simple structure.
