Problems solved by technology

However, for O-rings that are more widely used in industry with a large ratio of inner diameter I to wire diameter W (called "flexible O-rings"), vibration does not work because they are easily deformed and entangled
[0004] In addition, traditional O-ring automatic assembly methods are usually only suitable for installing O-rings on the outer circumference of the shaft or the inner circumference of the hole
However, this method cannot be applied to a groove for mounting an O-ring (particularly a flexible O-ring) on ​​the end surface of a workpiece, which is also widely used in industry.

Abstract

An apparatus (500) for mounting an O-ring (200) to a workpiece (400) includes a plurality of pick-up members (501) operable to move away from each other to contact and expand the O-ring (200) to O-rings (200) are picked up, or moved towards each other to release the O-rings (200); and a guide member (502) comprising a frusto-conical portion (5021) arranged coaxially with the groove (402) of the workpiece (400) ), the large end surface (5022) of the truncated cone portion (5021) is arranged adjacent to the end surface (401) of the workpiece (400), and the groove (402) is formed on the end surface (401), wherein the large end surface (5022) The diameter (D) of the groove (402) is substantially equal to the inner diameter of the groove (402), wherein the pick-up member (501) is operable to release the O-ring (200) onto the tapered surface of the frusto-conical portion (5021) such that the O-ring The ring (200) is pushed into the groove (402) along the tapered surface.

Description

technical field [0001] Embodiments of the present disclosure mainly relate to an O-ring operating device, and more particularly, to an O-ring separating, feeding and installing device and method. Background technique [0002] O-rings, also known as gaskets or torus connectors, are mechanical washers in the shape of a torus. An O-ring is an elastomeric ring with a circular cross-section designed to be placed in a groove and compressed between two or more parts during assembly to form a seal at the interface. O-rings can be used in static applications or dynamic applications where there is relative motion between the part and the O-ring. O-rings are one of the most commonly used seals in mechanical design because they are inexpensive, easy to manufacture and reliable. [0003] Under normal circumstances, O-rings are manually assembled, which is inefficient and labor-intensive, and significantly reduces the overall assembly efficiency of the workpiece. There is an increasing...
