PCB Positioning Section
This section is provided with a mechanism by which the PCB sent from the
PCB input section is positioned.
PEC Recognition Function
In normal cases, two ducial marks are put on a PCB and the coordinate data
and positional deviations are detected by the PEC recognition camera.
This function automatically corrects placement positions of components
according to the recognized positional deviations.
There are three kinds of PEC recognition functions - "Global", "Image",
and "Local".The global recognition function covers all positional deviations
over one PCB and is used to correct them. The image recognition function
is used to correct positional deviations for each individual patterns. The
local recognition function is used to correct positional deviations for each
component placement point.
PEC Recognition Section
Each beam is equipped with a PEC recognition camera and a light source for
illumination, making a pair with the placement head.
The PEC recognition camera is used to detect the ducial marks on a PCB
and the amount of the positional deviation from the ducial mark coordinate
data is calculated to automatically correct the position of a component to be
placed.
PCB Transfer Conveyor Section
The PCB transfer mechanism works to transfer the PCB (sent from the input
machine) to the area just before the PCB positioning section and carries out
the component-placed PCB to the output machine.
Pickup Position Teaching Function
This function is used to correct the component pickup position through
manual alignment operation.
The pickup rate might be improved by this function.
Automatic Feeder Axis Adjustment Function
When a component is picked up by the vacuum nozzle and shifted from the
correct pick-up position, this function uses the recognition system to correct
the deviations for accurate component placement.
By feeding the recognized amount of correction back to the pickup position,
the pickup position can also be brought close to the specied one.
Optimization of Pickup and Placement Order
As for each placement point in the pattern program, the pickup and
placement order can be determined.

Operation Sections
The machine is provided with touch screens and front and rear operation
panels based on human interface technology. The operation panels are
equipped with buttons and switches required for manipulation of the
machine.
The front operation panel is equipped with a keyboard and a track ball as a
pointing device. (Standard Equipment)
The [PNL CHANGE] buttons on the operation panels can be used to select
and activate either the front or the rear operation panel.
Placement Head Sections
These sections are provided with a mechanism by which the components
picked up by the nozzles are placed on the PCB.
There are two X-axis linear bars and each bar is provided with a placement
head. (2-Beam 2-Head). Each placement head has fteen tting holes for the
vacuum nozzles. Up to 15 types of vacuum nozzles can be attached to each
head. 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.
Touch Screens
The front and rear operation panels are equipped with touch screens to
display the operation windows. Various operations can be performed by
nger-touching the buttons that appear on the screen.
Light Tower
A light tower is located on the center of the machine.
The tower has some color lamps and a buzzer to indicate the machine status.
"PASS" Mode
When the machine is set in the "PASS" mode, it just carries the PCBs to the
output machine without placing any components on them.

Power Breaker
This breaker is used to supply or intercept the power to the machine.
The power breaker can be locked with a padlock.
Nozzle Stocker Sections
These sections are provided with a mechanism by which the vacuum nozzles
can be stored.
A placement head moves to the area above the nozzle stocker according to
the pattern program and picks up a vacuum nozzle or puts it back in place.
Pattern Program
This program is composed of groups of regulatory data that can be used
to control the machine and specify the components and PCB used for the
automatic operation. This is sometimes called "Model" and must be created
individually for each production PCB.
A pattern program is composed of the following data.
(1)
Operation Data
This data is used to totally manage a pattern program and composed of
PCB data, PCB recognition data, ducial mark data, and setup data.
(2) Placement Head/Nozzle Data
This data is used to allocate a nozzle to the specied position (Nozzle
No.) on the head.
(3) Placement Feeder Location Data
This data is used to determine which feeder Nos. various types of
components (to be placed on the PCB) should be allocated to.
Component IDs (types of components to be allocated) must be specied
for each individual feeder bases.
(4) Placement Data
The set parameters are used to place the components (IDs in the
placement feeder location data) on the points with the specied
coordinates in the designated direction. One step is allocated for each
component to be placed.
(5) Handling/Placement Data
This data is based on the above-described data (1) through (4) and
created through the optimization process. The displayed data shows the
order of component pickup and placement actions.
