Pins and dowels
Present cylindrical components by axis, end or feature for pressing and location.
Small assembly component presentation

Direct answer
How are clips, pins and rivets fed automatically?
Loose assembly parts are separated, orientated and singulated using bowl, step, centrifugal or flexible feeders, then transferred to a nest, tube, robot or insertion tool. The concept depends on symmetry, head features, hooks, rolling behaviour and the required assembly datum.
System and application overview
The final insertion condition defines the feeding task.
A cylindrical pin may need only axial orientation, while a headed rivet or spring clip can require face, rotational and leading-feature control.
The feeder and singulator should be designed together so the part remains stable through queue pressure, release and pickup.
- Define head, point, slot, hook or leg orientation at hand-off
- Manage rolling, shingling, nesting and interlocking in bulk and on track
- Provide one-at-a-time release with successful-pick confirmation
- Protect plated, coated or precision contact surfaces
Where it fits
Assembly components commonly considered for automation.
Representative parts and the receiving tool should be assessed together wherever possible.
Rivets and inserts
Orient heads and shanks for riveting, welding, heat staking or insertion.
Clips and retainers
Manage asymmetric legs, hooks and spring features for controlled placement.
Engineering decisions
Symmetry can simplify movement but complicate verification.
A part may travel easily yet still require sensors or tooling to distinguish the correct end or rotational pose.
Orientation features
Heads, chamfers, grooves and slots provide mechanical or optical reference points.
Queue stability
Round parts can roll; thin parts can shingle; clips can catch. Track and stop geometry must control each behaviour.
Insertion interface
The final nest, gripper, feed tube or tool guide determines acceptable position and tolerance.
Project definition
Information needed for an accurate recommendation.
The proposed method is selected from the actual component, accepted presentation and downstream process—not from a generic rate claim.
| Component drawing | Head, shank, tip, groove, slot, leg and functional contact features. |
|---|---|
| Surface condition | Plating, oil, coating, burr limits and surfaces that must not be marked. |
| Required pose | Axis, head direction, rotational orientation, pitch and release location. |
| Transfer | Escapement pickup, tube delivery, robot pick, press nest or insertion head. |
| Rate and buffer | Assembly demand, short stops, queued capacity and recovery behaviour. |
| Acceptance | Correct-pose percentage, double-feed limit, damage criteria and sustained transfer test. |
Evidence before approval
Include the receiving tool in acceptance planning.
The most useful evidence is a repeatable transfer into the actual or representative nest, gripper or insertion guide—not simply a correctly orientated part at the feeder outlet.
Common questions
Clip, pin and rivet feeder questions.
Can headed and headless pins use the same feeder?
Possibly if geometry and required presentation are compatible, but tooling and sensing must be assessed for each variant.
How are rivets transferred to the tool?
Options include track pickup, pneumatic tube transfer, robot handling or a dedicated insertion escapement.
Can spring clips tangle?
Yes. Open legs and hooks can interlock, so bulk depth, agitation and separation must be tested with production quantities.
Can the system detect the wrong end of a pin?
Mechanical gauging, sensors or vision can distinguish an end feature if it is sufficiently repeatable and visible.
