An apparatus for automatic placement of gaskets on a housing includes a base, the second feeding mechanism, a first detecting member, a bearing mechanism, an assembly mechanism, and a controller. The first detecting member can detect the position of the gaskets relative to the preset position. The detected results are transmitted to the controller by the first detecting member. The controller controls the second feeding mechanism to accurately adjust the position of the gaskets to preset position. Therefore, a projection of the gasket is accurately engaged in a mounting hole of the housing by the assembly mechanism.

A method of mounting an elastic ring, e.g., sealing ring, on a body via a mounting unit is presented, having at least three fingers which are movable relative to each other. The method comprises holding and clamping the ring on the exterior side of the fingers which extend into a cross-section framed by the ring, moving at least one finger along a circle or a plurality of fingers along a common circle or a plurality of concentric circles such that the elastic ring is stretched and the cross-section thereof is increased, moving the ring and the component relative to each other so that the component projects into the cross-section and the ring extends around the component, moving one or more fingers relative to each other so that the ring contacts the component in sections between adjacent fingers, and moving the fingers out of the ring. Also disclosed are a mounting unit for executing the method, and a ring mounting device including such a mounting unit.

An O-ring processing station for an automated mass production system includes: (a) at least one feed device operable to control discharge of O-rings from an output end of the feed device; (b) an indexing device having a plurality of O-ring retainers, the indexing device operable to advance each retainer to a loading position in alignment with the output end for receiving an O-ring from the feed device, and an unloading position spaced apart from the loading position for unloading the O-ring from the retainer; and (c) a pick-and-place robot including at least one end effector movable between a pick-up position in alignment with a retainer at the unloading position for removing the O-ring from the retainer, and a drop-off position spaced apart from the pick-up position for installation of the O-ring onto a workpiece.

Automatic seal applicator apparatuses comprise a seal applicator module comprising a conical element and a pair of jaws or fingers that separates a seal, such as an O-ring, a D-ring, or other like seal, from a dispensing sleeve, and automatically applies the same to a part. Moreover, the apparatus comprises a quick-release module for quickly and easily removing one or both the dispensing sleeve and the conical element. In addition, the apparatus comprises a turntable allowing multiple parts to have seals applied thereto automatically. Finally, a system of a plurality of seal applicator apparatuses may be utilized for applying a plurality of seals to parts automatically.

A mounting method for an anti-detachment elastic retaining ring is provided. A mounting device includes a guide sleeve and a target mounting shaft that is provided with a groove; the guide sleeve includes a conical section; the conical section includes a narrow end with a radial dimension less than a locking diameter of a retaining ring body and a wide end with a radial dimension greater than the locking diameter of the retaining ring body; the guide sleeve is coaxially coupled with a front end of the groove of the target mounting shaft; the wide end of the conical section faces the groove; the mounting device further includes a pressing sleeve; the pressing sleeve is fitted outside the guide sleeve and moveable axially along the guide sleeve; and a side of the pressing sleeve close to the target mounting shaft is provided with a release protrusion.

An O-ring processing station for an automated mass production system includes: (a) at least one feed device operable to control discharge of O-rings from an output end of the feed device; (b) an indexing device having a plurality of O-ring retainers, the indexing device operable to advance each retainer to a loading position in alignment with the output end for receiving an O-ring from the feed device, and an unloading position spaced apart from the loading position for unloading the O-ring from the retainer; and (c) a pick-and-place robot including at least one end effector movable between a pick-up position in alignment with a retainer at the unloading position for removing the O-ring from the retainer, and a drop-off position spaced apart from the pick-up position for installation of the O-ring onto a workpiece.

A manufacturing assembly for installing a snap ring into a bore of a multi-axial joint includes a ram tool configured to axially force the snap ring through the bore towards a retention groove with the snap ring in a constricted configuration. An axially distal end of the ram tool includes one or more engagement elements having a tapered engagement surface configured to apply a radially outward force to the snap ring during passage thereof through the bore to urge the snap ring to expand from the constricted configuration back towards an original configuration upon the snap ring reaching the retention groove. A funnel tool configured to constrict and the direct the snap ring into the bore includes an alignment key configured for reception within a keyway of the ram tool during installation of the snap ring to orient the funnel tool and the snap ring relative to the ram tool.

An apparatus for inserting a seal member into a seal groove includes a tray. The tray includes a holding groove formed in a front surface for containing the seal member. The holding groove is sized and shaped to correspond with the seal groove. A method of installing a seal member into a seal groove includes aligning the holding groove with the seal groove, and applying a pressure to a back surface of the tray, thereby deforming the tray and inserting the seal member into the seal groove.

Apparatuses for controlling fluid flow are important components for delivering process fluids for semiconductor fabrication. These apparatuses for controlling fluid flow require a variety of fluid flow components which are tightly packaged within the apparatuses for controlling flow. Servicing the apparatuses requires specialized equipment and methods which enable installation of seals in close quarters in apparatuses which are installed in the field. Seal retainers may be used to retain the seals during assembly of fluid flow components into apparatus for controlling flow.

A seal ring installation module comprises a seal ring pickup and transfer device adapted to pick up a seal ring and transfer the seal ring to a component. The pickup and transfer device includes a support member and an outer cylinder sleeved on the support member. The support member has an external shape or at least one external dimension corresponding to those of the component. One end of the support member protrudes from an opening at one end of the outer cylinder to pick up and support the seal ring. One of the outer cylinder or the support member is movable axially relative to the other and is adapted to, with the component axially aligned with and contacting the one end of the support member, transfer the seal ring supported on the one end of the support member from the support member to the component under a biasing force applied by an end face of one end of the outer cylinder.
