6) Execute the [RETURN] à [DIS REAL-IMG] commands to display the current real image at
the monitor.
7) While watching the monitor, turn the lens at the camera focusing side until the part’s legs are
clearly displayed.
8) Execute the [RETURN] à [ACQUIRED IMG] commands, then continuously press the [ZOOM
IN] command for as long as the brightness level remains acceptable. Next, execute the
[SCROLL] command and use the [Left], [Right], [Up], [Down] control keys to move the image
until the glass part’s legs are displayed. [STEP] can be pressed to change the number of pixels
traversed per operation. This function enables easy travel over long distances, and should be
used as necessary.
9) Although the value can vary somewhat depending on the camera being used, the focus is
acceptable if the difference between the gray value at the leg’s center and the gray value at
the body is 30 or less. If such a value is obtained, tighten the lens lock bolt (focusing is
completed).
10) If the obtained value is not 30 or less, repeat the adjustments described at items 4 to 9 above.
[6-15] Parts Camera X,Y,Q Measurement
1) Remove the nozzle and mount a resolution measurement jig.
* The jig to be mounted varies according to the camera type. Use of the wrong jig will result
in an error. Verify that the jig type is correct before beginning this measurement.
Camera type 1: Jig size: 8.4 x 8.4mm (BHPJ0460)
Camera type 2: Jig size: 27.4 x 27.4mm (BHPJ0190)
Camera type 3: Jig size: 36.8 x 36.8mm (BHPJ0220)
Camera type 4,7: Jig size: 73.6 x 73.6mm (BHPJ0170)
Camera type 6: Jig size: 18.4 x 18.4mm (BHPJ0180)
2) Place a dial gauge against one side of the jig, then turn the Q-axis until the jig is parallel (0.02
/ 100mm) to the X-axis.
3) Execute the following to raise the Z-axis, move the head to the [XC/YC] measured position
(see above), and perform the automatic measurement: [CAMERA]à [RESOLUTION] à
[PARTS CAMERA] à [START].
4) Following the automatic measurement, the “Parts Camera X,Y” values become the resolution
value. Note that the values varies according to the camera type as shown below.
Camera type 1 : 1435238(21.9um) < 1441792(22.0um) < 1448346(22.1um)
Camera type 2 : 4633395(70.7um) < 4653056(71.0um) < 4672717(71.3um)
Camera type 3 : 6271795(95.7um) < 6291456(96.0um) < 6311117(96.3um)
Camera type 4 & 7 : 2942566(44.9um) < 2949119(45.0um) < 2955673(45.1um)
Camera type 6 : 812647(12.4um) < 819200(12.5um) < 825753(12.6um)
5) If the X,Y measured values are outside the prescribed range, the camera height (focus) is
unsuitable. In this case, readjust the camera height until the X,Y values are within the
prescribed range.
[Ex] If the measured values are too low, lower the camera.
If both the X,Y values are within the prescribed range, proceed to the “Parts Camera Q”
adjustment.
6) Loosen the 4 lock bolts which secure the camera and turn the set screw until the Q-value is
within 0 +/- 655. After re-tightening the lock bolts, perform the measurement again.

[6-16] Camera Center XC, YC, Nozzle Holder Center X, Y Measurement
* Camera Center XC,YC and Nozzle Holder Center X,Y are measured at the
same time.
1) For camera types 1, 2, and 3, mount a 10mm back light nozzle in the holder
(3.7mm nozzle for camera type 1), then execute the following command
sequence to begin the automatic measurement: [CAMERA] à [CAMERA
POS]à [PARTS CAMERA]à [START].
2) For camera types 4, 6, and 7, mount a nozzle jig in the holder. (Camera
types 6 and 7 require a special jig, although the jig for camera type 4 can be
used if its end is painted white.) Execute the same command sequence as
that shown in step 1 above to begin the automatic measurement.
* When measurement is prevented by an error:
Because the real image cannot be displayed at the monitor when a line scan cameras is used,
align the monitor center with the jig center by eye.Use the inching operation to move head
until this alignment is achieved.Return to the “Temporary Camera Center XC,YC
Measurement” section ([7-13]), then execute the [XC/YC] --> [SET] commands and enter the
Proper data value. After entering the Proper data, return to the [CAMERA POS] command
and press [START] to perform the automatic measurement again.
3) After calibration, in case of a CCD camera, tighten the lens lock by hand and further apply a
small amount of LOCTITE 222. Do NOT retighten by using a tool.
[6-17] Nozzle_Select_Pos.Z Measurement (For Index Types Only)
1) Turn off the 200V power supply, then turn the Z-axis pulley by hand to raise the Z-axis until
the shaft holder makes light contact with the bottom face of the bracket.
2) Add 2333 pulses (2mm shaft radius + 1.5mm below bottom of bracket) to the Z-axis counter
reading at the point of contact to obtain the Nozzle_Select_Pos.Z value. After rotating the
holder so that there is no interference between the end of the shaft and the bracket, raise the
Z-axis to the Nozzle_Select_Pos.Z position and lock the servo.
3) Execute the following command sequence to perform an automatic data input: [NZZLE
SELECT] à [Zn] à [SET].

[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.
