[6-18] Adjusting the Nozzle Check Sensor (For Index Types Only)

1) Move the Z-axis to the Nozzle_Select_Pos.Z position, and the Q-axis to the position where the

counter reads “0”.

2) Temporarily turn the sensor volume to its center position.

3) Select nozzle 3.

4) Gradually cover the index hole from up, down, left, and right, then adjust the sensor beam

emitter up, down, left, and right, until the sensor beam passes through the center of the hole.

5) Lower the volume setting to the point just prior to the point where the sensor receptor’s red

LED goes off.

6) Verify that the green LED lights (stable status) regardless of whether or not the sensor beam

is blocked.

7) Lower the Z-axis 500 pulses below the Nozzle_Select_Pos.Z position and verify that the sensor

beam is not blocked.

[6-19] Nozzle_Select_Pos.X,Y,Z Measurement (Single Types Only)

1) Nozzle_Select_Pos.X,Y Measurement

1. Execute the following command sequence to raise the unit:

[POSITION] à [Module #] à [NOZZLE] à [STATION] à [UP].

2. Mount the nozzle jig which was used for X0/Y0 at the nozzle shaft.

3. Place a receiving jig at nozzle changer 1.

4. Turn off the 200V power supply and turn the X,Y,Z axis pulleys to find the position where

the nozzle jig can be inserted smoothly into the number 1 jig hole.

5. After positioning the X and Y axes, execute the following command sequence to

automatically enter the Nozzle_1_Select_Pos.X,Y data:

[NOZZLE SELECT] à [Xn/Yn] à [Xn1/Yn1] à [SET].

6. Measure all the Nozzle_Select_Pos.X,Y positions in the same manner.

* The above jig cannot be used at stations with mechanical chucks. Use a jig for mechanical

chucks at these stations.

* For 600 Module

2) Nozzle_Select_Pos.Z

* Because B1 and C1 types have UP limit stoppers, adjust so that no contact is made with the

stopper before beginning this measurement.

1. After completing all the Nozzle_Select_Pos.X,Y measurements, remove the receiver jig

from the changer and the nozzle jig from the nozzle shaft. Also raise the nozzle station.

2. Mount a nozzle on the nozzle shaft and move the head by hand to the first

Nozzle_Select_Pos.X,Y position of the single nozzle station.

3. Turn the Z-axis pulley by hand to lower the nozzle to the position shown below. This is

the Nozzle_Select_Pos.Z position.

1) For types other than C1 and B1:

•3.5mm spline type : Raise to a position 3666 pulses above the Z-axis Min. Limit.

•2.0mm spline type : Raise to a position 3000 pulses above the Z-axis Min. Limit.

2) For B1 and C1 types:

•3.5mm spline type : Raise to a position 4083 pulses above the Z-axis Min. Limit.

•2.0mm spline type : Raise to a position 3416 pulses above the Z-axis Min. Limit.

* Note that the UP limit for B1 and C1 types is slightly lower due to the stopper adjustment

which is required (see step 5). Therefore, lower the Z-axis and re-measure the

Nozzle_Select_Pos.Z position.

4. Execute the following command sequence to automatically enter the data: [NZZLE

SELECT] à [Zn] à [SET].

5. With the Z-axis at the step 3 position (see above), adjust so that the bottom of the nozzle

disk makes contact with top surface of the nozzle station. Set a dial gauge on the top face

of the nozzle disk and find the exact height at which contact is made with the top face of

the nozzle holder.

* If measuring with a dial gauge, be sure that the gauge is calibrated.

* After adjusting types B1 and C1 as described above, position the UP limit stopper against the

bracket, then turn the stopper another 1/2 a revolution in the bracket direction and lock it there.

6. With the changer raised, adjust the UP limit sensor. Begin by moving the sensor upward

until it switches off, then lower the sensor to the position where it switches on. Secure the

sensor 1mm below that position. Adjust the DOWN limit sensor by moving it downward

until it switches off, then raise it to the position where it switches on. Secure the sensor

1mm above that position.

7. Finally, verify that all nozzle detection sensors are operating properly. Both the green and

red LEDs should be lit when a nozzle is absent. If a nozzle is present, only the green LED

should be lit. Also use I/O commands to verify that inputs are correct.
