Feed mechanism for a terminal crimping machine
A feed mechanism for a terminal crimping machine includes a feed track and a strip locator. The feed track has a top plate and a side wall. The top plate extends from a front of the feed track to a rear of the feed track. The top plate is configured to receive thereon a terminal strip having a plurality of terminals arranged along a carrier strip. The terminal strip is configured to be moved from the rear to the front towards a crimping zone of the terminal crimping machine. The side wall has a fixed edge above the top plate. The strip locator is coupled to the feed track. The strip locator has a rail movably coupled to a support wall. The support wall is fixed relative to the feed track. The rail is biased against the terminal strip to force the terminal strip against the fixed edge of the side wall.

a strip locator coupled to the feed track, the strip locator including a rail movably coupled to a support wall, the support wall being fixed relative to the feed track, the rail being biased against the terminal strip to force the terminal strip against the fixed edge of the side wall.
2. The feed mechanism of claim 1 , wherein the side wall extends along a first side of the feed track, the support wall is fixed proximate to an opposite second side of the feed track, and the rail being located between the side wall and the support wall, the rail being moveable toward and away from the side wall.
3. The feed mechanism of claim 1 , wherein the support wall of the strip locator includes a protrusion extending from a bottom side of the support wall that engages a groove defined in the top plate of the feed track to align the support wall with the feed track.
4. The feed mechanism of claim 1 , further comprising a cover plate configured to attach to the side wall of the feed track and extend parallel to the top plate, the terminal strip being retained in a space defined between the cover plate and the top plate.
5. The feed mechanism of claim 4 , wherein the cover plate includes a slot extending through the cover plate that allows a feed finger of a feeder device to pass therethrough to access the carrier strip of the terminal strip to advance the terminal strip towards the crimping zone.
6. The feed mechanism of claim 1 , wherein the rail is coupled to the support wall using one or more springs to provide the biasing force that forces the terminal strip against the fixed edge of the side wall.
7. The feed mechanism of claim 1 , wherein the rail is movable to a released position by forcing the rail toward the support wall, the terminal strip being released from the fixed edge when the rail is moved to the released position.
8. The feed mechanism of claim 1 , wherein the rail of the strip locator comprises a lip that extends downward from the rail, the lip being positioned between a terminal barrel and a terminal body of each of the terminals and engages the terminal barrels.
9. The feed mechanism of claim 1 , wherein the top plate comprises a shoulder adjacent to the fixed edge of the side wall, the shoulder configured to receive thereon the terminal strip.
10. A feed mechanism for a terminal crimping machine comprising:
a feed track having a top plate and a side wall, the top plate extending from a front of the feed track to a rear of the feed track, the top plate configured to receive thereon a terminal strip having a plurality of terminals arranged along a carrier strip, the side wall having a fixed edge above the top plate;
a feeder device including a feed actuator operatively connected to a feed finger, the feed actuator configured to cause the feed finger to mechanically advance the terminal strip from the rear to the front towards a crimping zone of the terminal crimping machine; and
a strip locator coupled to the feed track, the strip locator including a rail movably coupled to a support wall, the support wall being fixed relative to the feed track, the rail being biased against the terminal strip to force the terminal strip against the fixed edge of the side wall.
11. The feed mechanism of claim 10 , wherein the rail does not make direct contact with the feed track.
12. The feed mechanism of claim 10 , wherein the rail is coupled to the support wall by plural pins, each pin including a spring surrounding a portion of the pin between the rail and the support wall, wherein the springs provide the biasing force that forces the terminal strip against the fixed edge of the side wall.
13. The feed mechanism of claim 10 , wherein the carrier strip of the terminal strip is forced into contact with the fixed edge of the side wall along a first side of the feed track, the terminals of the terminal strip extending from the carrier strip toward the support wall which is fixed proximate to an opposite second side of the feed track.
14. The feed mechanism of claim 10 , further comprising a cover plate attached to the side wall of the feed track and extending above the carrier strip of the terminal strip on the top plate, the feed finger extends through a slot in the cover plate to engage the carrier strip, the feed finger configured to advance the terminal strip towards the crimping zone.
15. An applicator for a terminal crimping machine comprising:
a crimping mechanism including an anvil and a movable ram, the anvil located in a crimping zone and configured to receive a terminal thereon, the ram having crimp tooling configured to crimp the terminal located on the anvil to a wire during a crimp stroke of the ram;
a feed track having a top plate and a side wall, the top plate extending from a front of the feed track to a rear of the feed track, the top plate configured to receive thereon a terminal strip having a plurality of the terminals arranged along a carrier strip, the side wall having a fixed edge above the top plate;
a feeder device including a feed actuator operatively connected to a feed finger, the feed actuator configured to cause the feed finger to mechanically advance the terminal strip from the rear to the front towards the crimping zone; and
a strip locator coupled to the feed track, the strip locator including a rail movably coupled to a support wall, the support wall being fixed relative to the feed track, the rail being biased against the terminal strip to force the terminal strip against the fixed edge of the side wall.
16. The applicator of claim 15 , wherein the applicator is at least one of a side-feed type applicator or an end-feed type applicator.
17. The applicator of claim 15 , wherein the rail is coupled to the support wall by plural pins, each pin including a spring surrounding a portion of the pin between the rail and the support wall, wherein the springs provide the biasing force that forces the terminal strip against the fixed edge of the side wall.
18. The applicator of claim 15 , wherein the terminal strip is bounded on a first side by the fixed edge of the side wall, bounded on an opposite second side by the rail, bounded below by the top plate, and bounded above by a cover plate attached to the side wall, such that the terminal strip has negligible tolerances in both a side-to-side direction and an up-and-down direction.
19. The applicator of claim 15 , wherein the anvil in the crimping zone is located in front of the front of the feed track.
20. The applicator of claim 15 , wherein the rail of the strip locator comprises a lip that extends downward from the rail, the lip being positioned between a terminal barrel and a terminal body of each of the terminals and engages the terminal barrels.
