Project Introduction:
A machine equipment manufacturer in Singapore that manufactures laser processing machines was developing a system for marking and labeling finished disk media. Instead of using a conventional laser scribe to cut into the delicate disk surface, they wanted to create a system that uses laser marking to avoid disk media deterioration and contamination
System Requirements:
This customer wanted to integrate a laser disk tagging system to create permanent and visible physical features on the disk media for identification and reference marking. The system needed to be comprised to include PC Control, CO2 laser beam generator, a pulse calibrator, beam reflectors, an attenuator, a Beam Modifying and Energy Stabilizing System (BMES), and disk handling.
The customer required an Industrial grade PC complete with at least 4 com ports, Digital and Analog I/O channels. The IPC will control the whole operating process of the laser marking apparatus

System Description:
In this system, Advantech provided the IPC-610 with six I/O and communication cards (PCI-1754, PCI-1739U, PCI-1780U, PCI-1710, PCI-1610CU and PCI motion card) to handle computing tasks and control all devices. The lasers pulse calibration is controlled by the PCI-1710.
The shutter and BMES is then controlled by PCI-1752U to make sure the right laser beam can enter the galvanometer. Through the galvanometer, the laser beam will be focused to the surface of a glass disk in order to mark it. Patterns designed in the computer will be sent to galvanometer through PCI-1739U to direct the laser beam to right x-y position on the surface of the disk. With PCI-1780U controlling the disk, the expected alphanumeric characters will be formed on the disk.
Conclusion:
This customer has achieved a field-proven laser process solution with selectable single or double side tagging while minimizing cost, development time and integration efforts. The following were achieved:
- Both Offline and Inline PC control are using the same CPU boards and I/O cards which is convenient for Application software development and integration.
- The LED indicators on terminal board (ADAM-3951) allow the customer to check the digital I/O status without the need to check the computer. The hardware implementation time can be saved as the wiring and its testing is easy by just checking the LED indicators onboard.
- PCI-1739U provides high density DI/O numbers. One PCI-1739U is enough to control all positions in the x-y scanner of the galvanometer. This minimizes the cost, space and necessary PCI slots in the PC.
