LCD Auto Inspect System

Project Introduction: LCD's are fragile products, especially during the manufacturing process. Built in clean rooms, the inspection procedure is operated through robot assembly which doesn't require need human operation, but heavily relies on a stable system to reduce the maintenance.

System Requirements: The customer required a controller that could control the LCD inspect automatically, which led to the following requirements:

  • An embedded operating system for easier maintenance and increased reliability.
  • A stable system that would not generate any dust in the clean room.
  • High computing capabilities for vision inspection.
  • Easy to install various extension cards.
  • Rich I/O's to connect different peripheral devices.

Project Implementation:

UNO-3074: Intel Pentium M Embedded Automation Computer with 4x PCI, 1x PC Card

System Description: The UNO-3074 installed with a vision card can check the LCD display quality and also monitor the manufacturing procedure through various peripheral devices. The system can operate without manual control, auto recording the manufacture information, and filtering out any failed units automatically. The UNO-3074 has various built-in abundant I/O's to fulfill different requests from various devices.

Aside from its abundant IO, the customer was thrilled with UNO's industrial-grade design, specifically with no internal cabling and supporting a wide-power input. These features not only increase the reliability, but also reduce the cost of maintenance. Moreover, the PCI slot also leaves the possibility of future expansion.

Conclusion: Equipped with an Intel Pentium M 1.8 GHz CPU, UNO-3074 features a fanless design with reliability and high computing. Furthermore the compact design with front access wiring makes it easy to install in a cabinet and with four PCI slots it is easy to install video or Fieldbus cards.
