8.7 PCB Barcode Scanner

8.7.1 Overview

[ 8

The PCB barcode reader is used to automatically record and decode barcodes on PCBs. The

PCB barcode scanner sends the read data via its serial interface to the transport controller and

then for further processing to the machine controller via the CAN bus.

The PCB barcode scanners are installed on the input side of the placement machine on the PCB

conveyor. Up to four devices can be retrofitted to each machine. The barcode scanners are fitted

so that the barcode labels on the topside and underside of the PCBs can be scanned on both

tracks of the dual conveyor.

The barcode scanners are available for 2D codes.

The PCB barcode scanners are fixed to the top and bottom profiled rail using retainers. These can

be positioned as required on the profiled rails, and aligned with respect to the barcode labels. De-

pending on the position of the barcodes, the barcode scanner can be easily assembled so that it

can read the barcodes lengthwise or at right angles to the direction of board transport.

8.7.2 Functions

The PCB barcode scanner supports the flexible manufacture of SMD products, and increases

placement reliability . It recognizes all the code types conventionally used in industrial applica-

tions.

The PCB barcode scanner reads the barcode label on the topside or underside of each incoming

PCB as they are transported onto the input conveyor. Based on the barcode information, the

SIPLACE Pro computer automatically selects the correct placement program from the previously

created barcode allocation list and sends this to the station. If a barcode filter is defined, only in-

formation that is identified as relevant within the barcode is compared. This procedure is carried

out without affecting the time, during placement of the PCB which is already in the machine. If sev-

eral PCBs with the same barcode enter in succession, the program is only transferred the first

time. The following requirements apply to all products to be produced using the PCB barcode:

– The component setup must be identical on all the machines on the line

– All PCBs must be of the same width
