[CHAPTER 6] Proper Data Measurement

Notes regarding vision processing board handling:

1. Never unplug or plug in cables, etc., when the power supply for the vision processing board and

monitor is on. Such actions can damage the vision processing board.

2. Always wear a wrist-band when touching the vision processing board with hands in order to

prevent IC damage caused by static.

[6-1] Max, Min Limit Position

Note: The plus/minus symbols shown with the X,Y axis servo counter values are

reversed for rear part-supply machines.

1) Display the [Max/Min] screen. At the [X] [Y] [Z] display items, select [X].

[MAX LIMIT] [MIN LIMIT] then displays.

2) Turn off the 200V power supply, release the servo lock, and move the head to the machine’s

right-side mechanical stopper for the [MAX LIMIT], and to the left-side mechanical stopper

for the [MIN LIMIT].

* Note that the MAX and MIN directions are different at rear part-supply machines.

See the figure below.

3) With the head pressed against the stopper, press [MAX LIMIT] or [MIN LIMIT], then press

[SET] and enter the counter value for this position directly to the machine.

4) Measure the Y-axis and Z-axis MAX and MIN limits in the same manner.

* For both the Y-axis Min_Limit_MFU and MTU, enter the value which was measured at the

mechanical stopper position.

[6-2] Temporary Adjustment of Lens Half Mirror Gap

1) After removing the light source unit, turn the half mirror’s cut face toward the rear of the machine

and temporarily secure it at the position where dimension “A” (see figure below) is 2.5mm.

2) Secure the light source unit after adjusting the tilt so that the dispersion plate is horizontal

to the base. If the tilt in the direction of the mounting bracket’s bend causes interference,

replace the mounting bracket.

Note: Be careful not to disconnect harnesses when mounting and removing the light

source unit.

Note: The camera part number is different at front parts-supply and rear parts-supply

machines. Be sure to verify the part number when changing cameras (refer to the Parts

List). Number labels are affixed to the camera head and camera controller. Always

assemble with same-number items. A mismatch may adversely affect performance, and

may even make image acquisition impossible. When changing cameras, be sure that the

camera head and camera controller are a matched pair.

[6-3] Focusing the Mark Camera

* Each time the number of linked modules is increased, the adjustment module becomes farther

away from the image display monitor, making focusing more difficult. To avoid this problem,

turn the machine power off and connect a portable external monitor to the image output

source for easy and accurate focusing.

1) Verify that the camera is mounted in a perpendicular position, and that the mounting bolts

are tight.

2) Adjust the conveyor width to the width of the plate jig for camera measurement, then place

the jig on the control module (ICM) conveyor.

3) Click the [LOADER] à[LOAD BOARD] commands. A message then displays inquiring where

(which module) the PCB is located. Execute the [CONTROL MODULE] à [CR] à [START]

command sequence to designate module 1 as the jig location and then clamp the jig. Verify

that the jig is securely clamped.

4) Execute the [PROPER] à [CAMERA] à [RESOLUTION] à [MARK CAMERA] command

sequence to turn on the camera lamp and to display the real image at the monitor. Move the

head until the characters or marks on the jig are displayed.

5) Loosen the bracket bolt, then turn the adjusting bolt to move the camera up and down until

the real image is in focus. When focused, retighten the bracket bolt.

6) Slightly loosen the adjusting bolt (do not loosen to the point where it makes contact with the

camera bracket) and insert an R-pin into the head’s through-hole to prevent falls.

[6-4] Securing the Half Mirror

1) After focusing the camera, partially cover the light source unit’s dispersion plate and check

the gap to the end of the half mirror.

2) Remove the light source unit again, and then, after noting the current half mirror position

(length), remove the half mirror from the lens.

3) Remove the half mirror set bolts (3 bolts) and apply silicone to them. Use care to avoid

dropping and losing the set bolts.

4) Based on the previously noted gap extending to the dispersion plate’s top face and the half

mirror position at that time, calculate the final position so that the gap is approximately 1mm,

then secure the half mirror at that position before the sealer dries.

Note: Avoid over-tightening the half mirror’s set bolts as this can adversely affect the lens

performance.

5) Mount the light source unit and verify that the gap is appropriate.
