aoiAs devices are becoming more sophisticated and customers are demanding higher quality, manpower inspection in production lines is hard to do well. Automatic Optical Inspection (AOI) is the key to success in today's production environment to detect faults sooner and more precisely while meeting the increased need for 100% inspection. Since AOI machines are an essential tool and are widely used in many industries including semiconductor, PCB, TFT-LCD, automobile, food processing and packaging, etc. in recent years, manufacturers are seeking more effective means of implementing their AOI system. Compared with bulky and space-consuming desktop computers to control equipment. Advantech provides a cost-effective AOI solution to integrate a Human Machine Interface (HMI) with visual inspection applications enabling users to not only simplify their detection configuration but also reduce the implementation costs.

AOI evaluates the quality of manufactured products with the help of visual information and uses a two-part machine: first a PC-based system performs the detect inspection and then a PLC based system controls the operation of industrial equipment and processes.  Industrial PCs (IPC) are often used as the main control device but these have some short-comings such as over sized computer cases which take up too much space and require a large cooling fan.  The customer planned to use a compactIPC to improve the old system and requested that the new computer was powerful enough to seamlessly execute programs and tasks; have enough I/O interface for future updates and extensions as well as a touchscreen for improved operation and maintenance control.  The solution also needed to offer a better way to display the inspection results and HMI information on the same screen to minimize staff's operating time and improve production efficiency.

Advantech's proposed solution included a space-saving automation computer, an industrial projected captive touch screen monitor, and HMI run time software with easy-to-use features.

Advantech's TPC-1551T touch panel computer is the latest to use the Intel Atom E3827 1.75 GHz processor and to feature a truly flat screen with a multitude of I/O ports while being able to operate in a wide range of temperatures.

The Intel Atom E3827 1.75 GHz processor is the latest CPU from internationally renowned processor manufacturer and features an enhanced performance and provides a smooth operating experience in a wide array of industries.

The WebOP Designer and Panel Express software are easy to use integrated development tools for operator panels which save development and labor costs.  WebOP Designer supports more than 400 communication drivers and users can effortlessly exchange data via simple communication settings (taking only a few minutes) and record the inspection data to generate excel reports.   These is no need to install two monitors for the visual inspection system and to the HMI system because Panel Express can be used to connect media between both systems (Ethernet Modbus TCP/IP) to display all the information on the same screen, thus fully integrating AOI applications with peripherals to facilitate daily use and maintenance tasks.

In order to ensure the quality of the manufacturing process, AOI is necessary equipment. However, a number of manufacturers may be hesitant to use it or put off upgrading their old system because of the time consuming and labor intensive process.  Advantech's integrated solution is able to bring great benefits to users such as using one screen to replace two-monitor configuration as well as providing compact hardware to save space, simple setting with an intuitive user interface to accelerate development time and cost, a wealth of software/hardware resources for future expansion, thereby speeding up users' AOI system implementation to boost manufacturing productivity.
