2.6. PCB Conveyor System
2.6.1. Configuration
In the PCB conveyor system, boards from the previous process are transferred, the
placement position is determined, and boards are fixed. This system is divided into three
stages, thus reducing the PCB swap time to the minimum. The flatness of PCB is
improved by affixing the bottom surface of PCB. A wide range of PCB sizes from small-
sized PCB's (30.0mm × 50.00mm) to large-sized PCB's (460.0mm × 400.0mm) can be
accommodated.
The PCB conveyor system configuration is shown below:

Width adjustment part
Adjusts the width of rails according to the size of PCB. It is composed of LM guide,
lead screw, chain, handle.
P
CB belt assembly
Composed of an AC (step) motor and a timing belt. For a 3-stage conveyor, PCB feed
belt is divided into three steps, and each is driven separately. For a 3-stage conveyor,
a PCB can be clamped by using a belt in the working area since in and out movement
of the PCB is possible without having to drive the belt in the working area.
Place stopper
Stops a PCB at a working position and hold the PCB in place until discharge if it is at
an out position.
PCB sensor
Checks the position of a PCB on the conveyor..
Edge fixer
This is one way of correcting the position of a PCB prior to the beginning of work
after the PCB has reached the working position. The correction is made in reference
to one side of the PCB by pushing into that edge.
PCB clamp
Holds a PCB that is in contact with the belt prior to the beginning of work after the
PCB has reached the working position. It is operated while interlocked with a back-
up table.
Hole fixer
This is another way of correcting the position of a PCB prior to the beginning of work
after the PCB has reached the working position. The correction is made in reference
to a hole in the PCB by inserting a pin into that hole. The hole fixer is operated while
interlocked with a back-up table.

Caution
Adjusting the conveyor width without checking conveyor
obstruction or the existence of foreign substance could
damage the conveyor.
Be sure to check conveyor obstruction and the existence
of foreign substance before adjusting the conveyor width.
