Edition 6.0 Chapter 2. Cam Box Adjustment [4/8]
2.7 Helical Gear Backlash Check
1. Check the backlash of the large helical gear using a dial indicator with shafts A, E, I,
and M at station 9. (Cam at 180 degrees)
2. The backlash between the two helical gears should be within 0.02 to 0.06mm.

Theta Index Unit
3. The backlash may be adjusted by moving the theta index unit to the right or left.
2.8 Cam Lever Stopper Adjustment
1. Turn the machine power OFF.
2. At 0 degrees, set the gap between the cam follower and cam as indicated below for
Station 1 Nozzle up/down, Station 1 tape feed, Station 9 up/down and Station 14
nozzle change.
3. Manually, turn each station’s solenoid valve OFF at zero degrees. (fig. 10)
The solenoid valve should be OFF when setting the dial gauge, and ON when making
adjustments. For the valve buttons: [Green = ON] [Orange = Off]
4. Set a dial gauge on the cam lever at the locations shown in fig 8 and measure the
clearance according to the table below:

5. When making adjustments, push the green button (on the valve) to turn the valve ON. Then,
manually toggle the valve ON and OFF to check the clearance. As a rule, set the clearance as
close to 0.04 as possible. (best condition)

2.10 Image Acquisition Timing Flag Adjustment
1. Adjust the two sensor flags “A” in fig 12, so that the two sensor LED’s turn ON when
rotating the Cam forward to 197 degrees. (Tolerance: 197 ± 1 degree)
2. Adjust flag “B” so the sensor lamp turns ON when rotating the Cam angle forward to 340
degrees. (Tolerance: 340 ± 1 degree). Ensure the LED remains ON for the duration of
time the flag is within the sensor.

3. The three sensors mentioned above serve the following purposes.
a. The vision system trigger sensor informs the VP card to take the component image
at 197 degrees. (station 5)
b. The part height trigger sensor informs the part height unit to take the component
thickness (nozzle length) image at 197 degrees. (station 6)
c. The dust check trigger sensor informs the part height unit when to check the
windows for dust etc. (checks from 110 to 340 degrees). (station 6)
Note: The three sensors mentioned above are NOT connected to the I/O. To monitor the
sensor operating conditions, check the LED’s at the following locations:

Note: In order to monitor the dust sensor signal, go to the I/O and temporarily turn Y042
OFF. Normally, this function is automatically controlled by the system software.
