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 the grooves in which O-rings (especially flexible O-rings) are mounted on the end faces of workpieces, which are also widely used in industry.

Abstract

The present invention disclosures an apparatus (600) for mounting an O-ring (200) to a work piece (400), which comprises a body (601) comprising a plurality of connecting holes (6015) for connecting apressure source (650) to the body (601); an annular groove (6013) formed on the body (601) and adapted to receive the O-ring (200); and a plurality of air channels (6014) formed in the body (601), the plurality of air channels (6014) being in fluid communication with the annular groove (6013) and the plurality of connecting holes (6015) to provide negative pressure with the pressure source (650)in the annular groove (6013) to suck the O-ring (200) in the annular groove (6013), wherein the annular groove (6013) is coaxial with a groove (402) formed on an surface (401) of the work piece (400)during the mounting so that the O-ring (200) is dropped into the groove (402) when the pressure source (650) is disconnected from the body (601) or provides positive pressure to the plurality of air channels (6014).

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...
