Data matrix identification on circuit boards

Machine manufacturer IPTE Germany GmbH from Fürth detects alternately arranged data matrix codes on circuit boards in motion with two ICR 850 devices. The reading devices are connected to the machine control system via the CDB 420 connection module. This solution’s advantages: time savings and the identification of mixed 1-D and 2-D codes.

>> The ICR 850 units are installed on the feed belt of a multiple panel puncher, where many individual small circuit boards are cut out from the large panel holding them. By reading the data matrix codes on the multiple panels, IPTE ensures that the right printed circuit is lying on the conveyor belt, that the gripper in the machine matches the printed circuit, and that the correct processing program is active. If a circuit board is detected that was found to be defective during an earlier testing process, it is recognised on the basis of its data matrix and diverted off the belt.

Industry-oriented connection module

The compact CDB 420 module was developed for the connection of stationary bar-code scanners and 2-D code-reading devices from SICK to the SICK CAN-scanner network, a host computer and a PLC unit. It is not only half the size of the former version, but also offers features such as PG screw connections with strain relief, IP 65 with standard scanner cable, a transparent lid that provides a view of the LED indicators and switch settings beneath it, mountability in a closed state, and plug-in connection to the scanner’s service interface, among other important installation and operational advantages.
