Mounting
1) Install each feeder in the feeder bank ②.
2) Check that the selector ⑥ is set to OFF, and the bank lifter u is set below the
bank stopper ⑧.
3) Insert the overall feeder exchange trolley ① into the chip shooter main unit until
the trolley stopper plate ⑪ touches the bank stopper ⑧.
4) Lock the trolley stoppers ⑤ at the left and right.
5) Set the selector ⑥ to ON. The feeder bank ② goes up and is installed in the
chip shooter main unit.
CAUTION
To avoid any accident caused by sudden activation of the machine,
turn off the power, close the air cock, and release the remaining air
before starting installation.
6) Insert the feeder connector ⑫ into the power supply ⑬ of the cover of the chip
shooter main unit. Then, insert the air coupler ⑭ into the female union ⑮ of
the cover of the chip shooter main unit.
Note: If you operate the machine even though one of the front, rear, left and
right stations of the overall feeder exchange trolley descends, the X and
Y axes move at the lower speed as if the cover is open.
Dismounting
1) Detach the air coupler and the feeder connector from the chip shooter main unit.
2) Set the selector to OFF.
The feeder bank goes down, and it comes off from the chip shooter main unit.
CAUTION
To prevent your body from injury and to avoid damage to the machine,
install the overall feeder exchange trolley only after the machine is
stopped completely.
Do not place your hand in the machine, nor move your face or head
close to the machine when operating the selector.
When operating the selector, be sure to check the selector so that you
cannot operate other switches, especially main power switch by
mistake.
3) Release the lock of the trolley stoppers at the left and right.
Note: If you use the overall feeder exchange trolley to attach the feeder bank
on the main unit of the machine, do not touch the grip

of the overall
feeder exchange trolley or do not impose any load on it while the
system is teaching the component pick-up position on each feeder or
while it is producing a PWB.

12.8 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 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 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.)
