1. Play in the reference pin: 60 (m or less
1. Fix the guide block, install (4 -0.006/-0.0008 inspection bar, and apply an IN load alternately from the 180-degree opposite
direction at position B. At this time, measure play in the shaft at position A using a dial indicator.
2. Distance between the reference pin and the transport rail CF PWB guide surface: 5.4 ±0.2 mm
3. Deviation in Y-direction between the right and left reference pins: Within 0.03 mm
2. With the guide block pressed up against the transport rail side, secure the fixing screw and take measurements.
1. To maintain repeatability of PWB clamping position in the pin reference scheme.
2. To ensure good position of the reference pin with respect to the reference hole in the PWB which has been transported to
the aligning position. To provide positional reference for the PWB clamped in the pin reference scheme.
3. To provide the reference for tilt of the PWB clamped in the pin reference scheme.
3. With the guide rail mounting surface used as the reference, measure deviation in reference pin positions between guide
block L and R.
1. Repeatability of PWB clamping position in the pin reference scheme is not maintained, resulting in poor placement
accuracy.
Guide rail mounting surface
2. The reference pin does not fit into the reference hole in the PWB. Deviation in the reference pin in a placement system
that does not recognize the BOC mark results in deviation in the placement position.
3. Deviation in the reference pin in a placement system that does not recognize the BOC mark tilts the PWB, resulting in
deviation in the placement position.

1. IN sensor adjustment position: 33 ±2 x 9.5 ±2 (See Fig. on the right.)
2. OUT sensor adjustment position: 33 ±2 x 36 ±2 (See Fig. on the right.)
1. IN motor start trigger generation timing (when transporting PWBs from an upstream machine to the local placer).
PWB width direction detection position adjustment (for PWBs of irregular shapes).
2. OUT motor stop signal trigger generation timing.
PWB width direction detection position adjustment (for PWBs of irregular shapes).
*Shows where the transport direction is from left to right:
In a configuration of left-to-right transportation, the IN sensor and OUT sensor are located in reverse way, just the opposite
to what is shown above.
With rear end reference, the sensor is mounted on the movable rail.
1. If the IN motor is late to start, it results in the PWB transport tact time increasing. (Solution: IN sensor 9.5 -> Make
smaller.)
An incoming PWB binds to oscillate on the transport belt, deviating components on it. (Solution: IN sensor 9.5 -> Make
smaller.)
2. Slow to stop: An overrun to a downstream machine. (Solution: OUT sensor 36 -> Make larger.)
Quick to stop: Increased transport tact time, insufficient feed downstream the line. (Solution: OUT sensor 36 -> Make
larger.)

2. The stopper plate must move smoothly.
Turn it two turns from the fully closed position and secure it in position with the lock nut.

2. Turn ON and OFF air to observe how the pressure plate moves. If it looks binding, check parts installed at the pivot of
the pressure plate and stopper clevis. A washer may be wedged in, a part may be missing, or the adhesive may be
squeezed out.
1. PWB clamping speed.

1. High speed: Ceramic and thin PWB cracked.
Low speed: Unable to stop the PWB at a good position.
2. The stopper frame does not move and the PWB cannot be stopped.
The stopper frame is slow to move and the PWB cannot be stopped at a good position.
