⑥ Create the image data of the reference corner as same as a bad mark.
z Select the center color of the monitor for the [Type]. When the tray color is black,
select "White Search".
z Input the image code name.
z Both the teach camera 1 (main teach camera) and the teach camera 2 (aux. teach
camera) are available. (The default setting is the teach camera 1.)
z Input the image capture area. Input the lengths in the [Search Area X] and the [Search
Area Y].
(Recommended length: 0.5 to 1.0mm)
z Enter the threshold of black or white in the [Brightness]. (Standard: 127)
z Adjust the gain and offset values so that the tray image is displayed in black and the
background is displayed in white (for a black tray).
⑦ Execute image test. When the image test ends successfully and “OK” appears, write down
the value of “Measure”. (Example: Measure=255)
The search area is

⑧ Put the tray in the reverse direction. Make sure the tray covers the search area. If the tray
locates out of the search area, repeat the procedures from step ③.
Execute image test to make sure the result will be “NG”.
⑨ Write down the value of “Measure”. (Example: Measure=0)
When the center value of step ⑦ and ⑨ is close to 127 entered in the [Brightness], it means
the mounter recognizes black and white correctly.
Center value = Measure value at ⑦ + Measure value at ⑨ /2
(Ex.: Center value (255 + 0)/2 = 127)
If the calculated value is not close to 127, enter the actually calculated value in the
[Brightness].
⑩ Save the image data. Close the image data edit window.
⑪ Right-click the [Image Code for Ref. Corner] and select the created image data.
Make sure the search
area locates within the
tray corner.
Write down “Measure”
value, the result of the
image test.
Make sure the result
of
Image Test is “NG”.

Application
Tray orientation is checked under the following conditions.
Tray orientation is checked just before the tray component is picked up during a job run. The
mounter stores the tray orientations until the job is cancelled.
When components run out, the mounter checks the orientation of the next tray linked with the
component run out.
If the cover of the tray feeder is opened for component replenishment, etc. during a job run, the
stored tray orientations are erased. Tray orientations are checked again if the job is
restarted again.
Action:
① When a tray orientation check error occurs, stop the alarm and recover from the error.
At this time the tray keeps pulling out from the stocker.
② The [Edit&Teach] button appears in the Run window. Click the [Teach Coordinates] to
move the teach camera over the tray corner.
③ When the teach camera moves to the tray corner, the following window appears. Select
the next operation from the following three ways.
④
Continue: Selecting the [Continue] ignores a failure of tray orientation check and
continues a job run.
Image Edit: Selecting the [Image Edit] opens the image data edit window. Re-edit the
image data and restart a job run. At the start of the job, the tray orientation
is checked.
Return tray: Selecting the [Return Tray] pulled the tray back into the tray feeder. Check
the tray orientation. If the tray orientation is wrong, put the tray in the
correct orientation and restart a job run. At the start of the job, the mounter
checks the tray orientation.
Note: Not only putting the tray in the wrong orientation, improper setting of a tray may cause a
failure of tray orientation check. When putting a tray on a pallet, be sure to press fit against the
positioning block and clamp the tray securely.
