Purpose (Base Mark Position Offset)
The mark (center) is the base mark position taken using the PEC recognition camera
when the head rotation center is moved onto the component recognition camera.
Note:
Normally, when the "Head Rotation Center Offset" teaching has been performed, this teaching is to be
performed using the same head. However, escape from the "Head Rotation Center Offset" window
once and save the data, and then, go to this teaching operation.
Teaching Procedure
(1) Perform the [All Zero] operation in the "Control" window.
(2) Place the QFP glass jig with the printed side turned down, on the jig storage space
(Component Recognition Lighting Unit section).
Note:
Clean the jig storage space, vacuum nozzle, component recognition camera upper surface and QFP
glass jig using a soft and clean rag dipped in alcohol.
Clean the vacuum nozzle with alcohol applied to the tip.
(3) Set the HA19C nozzle in the nozzle stocker and enter "HA09C" or "HA19C" in the
nozzle arrangement position for the subject stocker.
Set it onto the nozzle No. 1 position on the head in question using the nozzle change
operation (Unit Adj.).
NOTICE
Fig.A33
Basically, nozzles are not attached manually. When it is
unavoidable, take care so that the unit (such as PEC recognition
camera after the head change, etc.) does not touch and scratch the
side view camera or light projector.
When the nozzle is attached manually, enter "HA09C" or "HA19C"
in the nozzle arrangement position for the subject head using the
debug operation.
If it is not entered, the QFP glass jig can not be picked up.
