Rivet dispensing systems and methods of use thereof

1. A rivet dispenser system comprising:

a rivet receiving member defining a channel therein, wherein the channel includes a curved region, the rivet receiving member comprising

a first port communicating with the channel and configured to receive rivets; and

a second port communicating with the channel and configured to dispense rivets;

wherein the channel extends between the first port and the second port and is configured to transport rivets from the first port to the second port in a series arrangement and in a preselected orientation;

a seat member communicating with the second port and configured to selectively engage with a rivet holder of a resistance spot rivet welding apparatus and introduce a single rivet to the rivet holder at one time, wherein the seat member comprises jaws configured to forcibly contact the rivet and prevent the rivet from changing at least one of a position and an orientation with respect to the seat member; and

an actuation member configured to move a rivet independently of the seat member, wherein the actuation member comprises

a lever, and

at least one of an actuator and a piston in communication with the lever,

wherein the at least one of the actuator and the piston is configured to apply a force to a first end of the lever to move a second end of the lever from a first position to a second position, such that the lever moves a rivet on the seat member to a secondary position above the seat member including the jaws.

2. The rivet dispenser system of claim 1 , wherein the lever comprises a protrusion configured to inhibit additional rivets from advancing from the second port onto the seat member.

3. The rivet dispenser system of claim 1 , further comprising a tensioner comprising a shape configured to move through at least a portion of the channel.

4. The rivet dispenser system of claim 3 , wherein the tensioner further comprises a finger configured to extend into the channel and retract from the channel.

5. The rivet dispenser system of claim 3 , further comprising a secondary channel in communication with the channel, wherein the tensioner is configured to move into the secondary channel to enable rivets to be received by the channel.

6. The rivet dispenser system of claim 3 , wherein the tensioner comprises a protrusion suitable to engage a rivet dispenser reloading system to move the tensioner within the channel.

7. The rivet dispenser system of claim 1 , further comprising a drive unit comprising a first linkage and a second linkage, each linkage pivotally coupled to the rivet receiving member, the drive unit configured to move the rivet receiving member along a path to traverse between a first position and a second position.

8. The rivet dispenser system of claim 7 , wherein the path is arc shaped.

9. The rivet dispenser system of claim 7 , wherein the drive unit comprises:

a bar linkage comprising the first linkage and the second linkage;

a main carriage connecting the first linkage and the second linkage;

a secondary carriage connecting the first linkage and the second linkage; and

an actuator configured to move at least one of the main carriage and the secondary carriage.

10. The rivet dispenser system of claim 9 , further comprising a spring connected to the main carriage to urge the rivet receiving member into the first position.

11. The rivet dispenser system of claim 1 , further comprising a rivet sensor configured to determine the quantity of rivets in the channel.

12. A resistance spot rivet welding apparatus comprising the rivet dispenser system of claim 1 .
