Switch, Button and

Indicator

For more precise separation, machine vision

software is used to set the cutting coordinates. A

picture is taken of the PCB and cutting coordinates

are calculated and sent by the machine vision

software to the PCI-1240U motion control card.

The laser starts cutting the PCB, using PCI-1240U’s

interpolation features for the rounded and irregular

shapes. PCI-1750 is used for on/off control of the

laser beam.

At completion, the laser is secured, the warning

light is switched off, and the fixture moves out

from the separation area while a second fixture

moves simultaneously into the separation area. The

operator picks up the fixture with complete PCBs

and replaces it with a new one.

Product Implementation

•

PCI-1240U is a 4-axis universal PCI stepping/

pulse-type servo motor control card, and was

used to control the laser movement in this

application.

•

PCI-1750 is a 32-ch isolated digital I/O

and counter card, used for simple fixture

movement, sensor input signals, operator

interface communications, and on/off control

for the laser.

•

Both cards are placed in an IPC-644 4-slot

MicroBox Desktop/Wallmount Chassis for

compact and protected storage.

Conclusion

•

The use of PCI-1240U together with machine vision software has resulted in a PCB separator

with cutting precision of ±0.01 mm.

•

The interpolation features of PCI-1240U made it unproblematic to perform cutting of rounded and

irregular PCB shapes.

•

With a PC-based system, integration with machine vision software was quick and easy

•

The customer was so pleased with the semi-automatic PCB separator that another fully-

automatic model has since been designed with Advantech products.
