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
Component B
Component A
Note: Components A and B should
another by at least 4mm.
