Semi-Automatic PCB Separator

SMT/PCB Industrial Assembly

China

Introduction

After many tough years, the PCB industry has learned that survival relies on investing in new

equipment and technology. Chief among the new PCB markets is mobile communications, where

handsets need highly compact and flexibly shaped PCBs. To meet this demand, a machine

builder in China used Advantech chassis, I/O and motion control products to create a new

general-purpose PCB separator. The new machine offers high precision, and allowed separation

of complex PCB shapes.

Project Requirements

•

To deal with the demand for smaller PCBs, the

system had to be very precise.

•

PCBs for handsets required rounded and

irregular edges.

•

Integration with machine vision software

needed to be easy and simple.

Solution Description

A PCB separator is used to cut PCB boards into

separate circuits. By keeping several identical circuits

on the same physical board during component

placement, the pick-and-place tools do not have to

be changed out so often. This speeds up component

placement, which usually is the bottleneck of a PCB

production line.

The system starts with the operator placing a fixture

filled with PCB boards into the machine. When the

fixture is in place, the operator presses a button to

activate the PCB separator. PCI-1750 captures the

button signal with an input channel and uses an

output channel to move the fixture to the separation

area. A sensor confirms that the fixture is in place

by sending a signal to an input channel on PCI-

1750. This unlocks the secured laser cutter, turns

on the warning light, and initiates the machine vision

software.
