12.12 Handling a Gripper Nozzle
This nozzle is designed exclusively for the KE-2000 series of products 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.
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. Its grip
strength is appropriate enough to pick up/place a component stably.

2. Specifications
(1) Required components and software
− A floppy disk on which a nozzle information file is stored is supplied with a
nozzle. This disk is required to use a gripper nozzle.
− The software version of the main unit that supports control over a gripper
nozzle is 1.11 or higher.
− The dimensions of a gripper nozzle arm should match a shape and size of
each component and a shape of a feeder such as a tape and tray.
[See “(5) Applicable components and packaging style”.]
(2) Method
Centering method: Laser and vision
(3) Component placement precision
Component placement precision : ± 0.3 mm or less (3 )
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 more 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 kg 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
