[Basic Operation]
At regular time intervals, the reference mark on the
fixed camera is recognized immediately before the
camera recognizes parts. After the position of a part
after its movement to above the fixed camera is
compensated for, based on the result of reference mark
recognition, the part is recognized.
[Operating Conditions]
1. When a specified time has lapsed during automatic production, the reference mark is recognized
immediately before parts are recognized.
2. When time has lapsed after motion stop, the reference mark is recognized immediately before part
recognition after automatic production restarts.
3. After power supply has restarted, the reference mark is recognized immediately before the first part
recognition.
4. The reference mark on the fixed camera is not recognized in the aging and simulation modes.
4-3 Pickup
[Basic Operation]
Unless there are any restrictions, parts move to the supply section according to the order defined in the
path of machine model data, and they are picked up continuously. When "Pickup Check" of part data has
been set to "ON," pickup check is carried out.
The operation of the pickup check differs, depending on part categories. For parts belonging to Category A,
pickup check is carried out with a pickup check camera used. For parts belonging to categories other than
A, pickup check is carried out with a pickup check sensor in the upper part of the fixed camera. The
number of parts that can be picked up simultaneously differs, depending on the part categories.
[Part Categories]
The multifunctional mounter can pick up larger-size parts that high-speed mounters cannot do by changing
its pickup check methods and recognition methods appropriately according to the sizes of parts.
As the result of that the scope of the sizes (width, length, and height) of parts to be handled has been
expanded, there are various operating conditions according to the sizes of parts to be handled, which are
determined by interference among parts when multiple parts are picked up simultaneously, interference
with a height recognition camera, conditions for nozzles to be used, etc.
In order to correspond with the characteristic of each part size, for the multifunctional mounter, "part
categories" defined by part sizes have been established. According to the part categories, the number of
parts that one head can pick up simultaneously, pickup check methods, RT and RN rotational restrictions,
recognition methods, and nozzle types change.

- Number of parts that can be picked up simultaneously
Number of parts that can be picked up simultaneously with no interference with parts picked up by the
adjacent index after the RN axis has been rotated once and with the tape on the top of the part cassette.
- Rotational restriction
Restriction for preventing interference with the tape on the top of the cassette when the RT or RN axis is
rotated at the pickup position. When this rotational restriction is imposed, the RT axis is rotated only
counterclockwise. In addition, the RN axis cannot even be rotated.
- Pickup check camera rising
When relevant large parts are picked up, a pickup check camera rises.

[Nozzle Type]
The multifunctional mounter has three types of nozzles (standard, long, and short). It uses an appropriate
one of these nozzles according to the part categories and picks up parts.
Nozzles corresponding to the part categories are shown in the table below.
Nozzle Types According to Part Categories
Category Nozzle Type Nozzle ID Nozzle Length Remarks
A,
B1, and B2
Standard 201 to 300
Same as the
standard nozzle
-
C,
D,
and F
Long 301 to 400
0.5 mm longer
than the standard
nozzle
Parts picked up by the long nozzle do not interfere
when the adjacent index is the standard nozzle.
E
and G
Short 401 to 500
5 mm shorter than
the standard
nozzle
Used for parts with a thickness of 10.5 mm or
more
<Points to Note>
- The end of the name of the long nozzle is “L” and that of the short nozzle is “S.”
Example: BF60400 (standard nozzle), BF6040L (long nozzle), BF6040S (short nozzle)
- The short nozzle is used only for parts supplied from the tray unit. (Parts supplied from the cassette
cannot be picked up.)
- The width of nozzles with large width (13 mm or more) is recognized as 13 mm.
[Pickup Check]
Concerning whether parts pickup check is carried
out or not, you can select “ON(1)” or “OFF(0)” in
“Pickup Check” displayed after selecting “Data
Editing,” “Part Management,” and “Sequence
(Multifunction)” in this order.
