SMT-Feeder-Kalibriervorrichtung für FUJI NXT (S-FFCJ10)

Four symptoms that all trace back to feeder drift

A feeder that drifts does not announce itself. It shows up as a throw rate that climbs for a week, then as a patch of failed boards, then as a customer call. These four symptoms are the ones our customers name first.

• Feeding position deviation. The nozzle arrives off-center; components are picked at an angle or missed entirely, and the error repeats on the same slot shift after shift.
• High deposit (throw) rate. Components are discarded mid-cycle. The scrap count climbs quietly while the line keeps running — the most expensive way to discover a bent feeder body.
• Patches of defective rate. A whole section of boards fails the same test. One feeder feeds one part on every board, so a mechanical fault prints itself across the run.
• Lost production efficiency. Every manual re-teach, trial placement and line stop burns hours you cannot invoice — and none of it fixes the mechanical cause.

What the jig actually is

Not a software offset. A physical reference the feeder is checked against — the same reference, read the same way, on every shift.

• Calibration jig base. A machined base with interchangeable sub-bases. One base serves CP-4, CP-6 and IP/QP BFC style feeders — the sub-base, not the bench, is what changes per feeder family.
• X-Y digital micrometers. The pickup point read to a hundredth of a millimetre. X reveals a bent feeder body; Y is adjusted through the feeder's own eccentric screw until the mark centers.
• Master gauge and tool scope. Zero the crosshairs on the gauge's calibration circle, then read the feeder's steel tape against the same reference. Verification against hardware, not memory.
• Feeder control zones. Precise 8×2, 12×4, 16×8 and 24×8 mm feeder control zones cover the tape widths running on your line, so the tape advances against the correct-width reference.

Five steps from crate to verified feeder

The whole check is one operator and five minutes per feeder. The steps below follow the operation manual shipped with the jig.

• Switch on and self-check. Connect the signal wire to the display VIDEO plug and the power supply. On power-up the press-pole returns to its original position and the display shows a cross cursor — the jig has completed its self-check.
• Install the sub-base. Slide the sub-base for your feeder style forward to the 1st alignment pin (CP-4 / CP-6) or the 2nd pin (IP/QP), keep it against the right-hand guide, then tighten the locking screw.
• Zero on the master gauge. Seat the master gauge on the sub-base, focus the tool scope, center the crosshairs on the gauge's calibration circle with the micrometers, then press zero on the X and Y micrometers.
• Read the feeder. Load the correct-width steel tape into the feeder and place it on the sub-base. Advance it — by turning the feeder advancement cam clockwise for CP-4/CP-6, by hand for IP/QP — and check the tape hole against the crosshairs on screen.
• Adjust or reject. Y: loosen the locknut on the eccentric screw and adjust until the mark centers. X: no adjustment exists — beyond ±0.25 mm the feeder body is bent and the unit goes to repair, not back to the line.

One jig, many feeder families

The S-FFCJ10 ships as the FUJI NXT configuration. The same platform covers the feeder families below; the sub-base, pedestal and control-zone set are confirmed per machine model when you order.
