System Requirements:
The whole system requires a long time to work, and it requires high reliability of the main control equipment.
The main control equipment industrial computer is installed in the terminal machine system. The terminal machine system is generally placed in the work shop, and is equipped with an automatic transmission system, which is greatly affected by harsh environments such as vibration and dust.
Because the number of data channels to be collected is not large, the number of interfaces that need to be expanded is not much, usually 1-2;
Because you want to print the test results, you need to print the interface;
Because it is necessary to debug equipment, set parameters, display results, etc., VGA interface and PS2 interface (separate) are necessary;
Because it is necessary to connect some PLC control devices, COM port is also necessary;
If an abnormality is detected during the test, an alarm must be requested in time. Therefore, the main board must be equipped with a buzzer. The detection program will generally use the buzzer;
The main control system needs to complete the functions of information collection, processing, analysis, transmission and communication. The CPU performance cannot be too low, but it is generally not required to be too high.
System specification:
The equipment for detecting PCB surface graphic quality (such as surface defects, open circuit and short-circuit) is used for quality inspection of semi-finished products in the production process. It is a key technology for high-precision single-layer printed boards, especially multi-layer printed boards. The test system integrates optics, precision machinery, identification diagnostic algorithms and computer technology. During the inspection, the machine automatically scans the PCB through a charge-coupled device (CCD) or laser, collects the image, and sends it to an industrial computer for processing. The data is then compared with the standard data in the database to detect defects on the PCB and displayed or identified on the monitor or automatic identification system. Defects for repairs by maintenance personnel.
