6.4 Placement Heads
Basically, the cycle *1 through *6 is repeated alternately on both Beams A and
B (placement heads).
The placement heads work according to the condition specified in the pattern
program, etc.
*1 P.C.B. Recognition (Placement Position)
Individual components on the P.C.B. are recognized to detect the positional
deviations (deviations of component placement positions).
(This recognition is performed only when the function is enabled in the
pattern program.)
*2 Nozzle Change Operation
A proper vacuum nozzle is selected for components and the attached nozzle
is replaced with the proper one.
The vacuum nozzle on the placement head is stored in the nozzle stocker
and the required vacuum nozzle is taken out of the stocker.
*3 Component Pick-Up (Tape Feeder, Vibratory Stick Feeder,
Multi-Layer Tray Feeder)
Components are supplied from the feeder which corresponds to the pattern
program and the vacuum nozzle picks them up.
In normal cases, one beam is used to pick up two pieces of components of
Heads #1 and #2.
Tape feeders, vibratory stick feeders, and multi-layer tray feeders are pre-
pared. (Each feeder is optional.)
*4 Component Recognition
The image of the picked component is captured by the component recogni-
tion camera and recognized by the recognition unit to detect the deviation
in the pick-up position.
*5 Component Placement
Components are placed.
The machine corrects the deviations of the P.C.B. and the components de-
termined through P.E.C. and component recognition and places the compo-
nents accurately on the specified positions.
In normal cases, one beam is used to place two pieces of components of
Heads #1 and #2.
*6 Rejected Component Discharge Operation
The components rejected as a recognition error are discharged.

Note: Fig. 1.26 shows the maximum number of installable feeders, assuming
that the same type of feeders are installed. The location of tape feeders
is just one example.

(2) Stick Feeder (Vibratory)
Max. 12 feeders (when only vibratory stick feeders are installed)
One vibratory stick feeder occupies six feeder slot Nos. (lanes).
The following shows the feeder slot Nos. (lanes) for which vibratory stick
feeder units can be registered.
Table 1.8
(3) Tray Feeders
Max. 2 Feeders (Up to 360 types can be used)
Ref.: Tray feeders do not give any effect to the number of installable
tape and stick feeders.
Note: The number of installable feeders varies according to the combination
of tape and stick feeders. Consult our sales personnel for details.
