12.18 R-ATC Plate
An R-ATC unit is attached on an RS-1R instead of an ATC unit.
The R-ATC unit has the structure that allows its slide plate section to be replaced with another one,
and this allows the slide plate to be replaced according to a nozzle to be used.
The following two slide plates are provided: a standard plate is attached on the machine by
default.
- Standard plate (ATC0001): its hole assignments are the same as those of the ATC unit of an
RS-1.
- Optional plate (ATC0002): this plate has an ATC hole that allows a very large type 1-nozzle
to be attached on the ATC.
The shape of each plate is shown below.

The number of holes of each plate is shown in the table below.

12.19 Gripper Nozzle
This nozzle is designed to pick up and/or place on a board a component whose top has no
picked-up area, and it is available to laser and vision recognition.
12.19.1 Features
The gripper nozzle uses its “fixed arm” and “swing arm” together exclusively to pick up and/or
place a component whose topside has no picked-up area from the component side. Its grip
strength is appropriate enough to pick up/place a component stably.

12.19.2 Specifications
(1) Required parts and software
- USB memory containing a nozzle information file that is supplied to the customer
together with the nozzle in the same package
- Gripper nozzles that are appropriate for the shape and size of each component and the
shape of a feeder unit (such as tape and tray)
(See “(5) Applicable components and packaging style.”)
(2) Method
Centering method: Laser
(3) Component placement precision
Component placement precision : ± 0.3 mm or less (3 σ)
Note that the attained precision may vary depending on the shape of a component.
When the system places a component whose portion to be aligned with laser has an
edge, whose molded part has a burr, or whose portion to be inspected with the system
cannot be fixed to a pick-up device, the precision described above cannot be attained.
(4) Limited adjacent components
When the system places a component, a gripper swing arm opens, so it may be in contact
with an adjacent component.
Therefore, there are the following two restraints on operations of a gripper nozzle:
- The height of a component to be placed with a gripper nozzle should be 3 mm or higher
than that of adjacent components.
- The side of a component to be held with the swing arm of the gripper nozzle should be
far from adjacent components by 4 mm or more.
(See the figure below.)
(5) Applicable components and packaging style
Applicable components:
• Connectors
(the top side cannot be picked up with a standard nozzle)
• Lead pitch (1 mm or wider)
• Weight: 5 g or less
(This value is subject to change depending on the shape of a component.)
• There should be a flat area on the top of a component against which the fixed arm
can be pushed. (to prevent a component from inclining when the X-Y axes moves)
Packaging style:
• Taping and tray
