3.3 PCB Positioning Section
The PCB positioning section is equipped with a mechanism by which the PCB
sent from the PCB input section can be xed (positioned) securely.
In the PCB positioning section, the placement head moves to the area above the
xed PCB according to the pattern program data and places the components on
the PCB.
When a program change operation is performed, it is required to rearrange the
PCB support pins and set up the conveyor width.

Notice
Do not put any foreign substance on the PCB positioning section.
Otherwise, the machine will break down.

3.4 X/Y Beam Section
This section is equipped with a mechanism by which the placement heads can be
shifted.
By shifting the placement heads in the X and Y directions, the vacuum nozzles
can be attached or detached and some components can be picked and placed on
the PCB.

WARNING
Those who wear implanted pacemakers are not
allowed to work inside the machine.
This machine uses strong permanent magnets in the
moving areas of the X/Y beams.
The pacemaker may be affected by the magnetism
and a serious accident will result.
CAUTION
Strong Magnetism
•
Do not bring any metal of high magnetizability
close to this.
Otherwise, such metal will easily be magnetized
and attracted, causing an injury to the operator or
breakdown of the machine.
•
Do not bring any object such as a magnetic
card and a watch close to the machine. Such an
object can easily be affected by the magnetism.
The data of the magnetic card might be cleared or
a watch, etc., may be damaged due to the strong
magnetism.
Notice
Keep the linear guide grooves clear of any object.
Otherwise, an object in the groove may be trapped in the moving part,
causing the machine to be damaged.

3.5 Placement Head Section
This section is equipped with a mechanism by which the components picked up
by the vacuum nozzles can be placed on the PCB.
A placement head is arranged on each X-axis linear bar (2 heads in total). (2-Beam
2-Head)
3.5.1 High-speed Head Section
There are fteen locations for mounting the nozzles on the high-speed Head, and
a maximum of fteen types of nozzle can be mounted.
Each head is also provided with a line sensor. The line sensor is used to detect a
component to be picked up and a vertical component. It is also used to measure
the component thickness.

Notice
(a) Keep the diffusion plates of the placement heads clear of oil, nicks,
etc. Otherwise, an error may occur during component recognition.
(b) Do not bring any magnetized object such as a magnet close to the
vacuum nozzles.
Otherwise, an error may occur during component picks and
placement.
