System Requirements:

The whole system requires long-term work, and the reliability requirements of the main control equipment are high;

The main control equipment industrial computer is installed in the terminal whole machine system. The terminal whole machine system is generally placed in the work shop, and has an automatic conveying system, which is greatly affected by harsh environments such as vibration and dust;

Because there are not many data channels to be collected, there are not many interfaces that need to be expanded. Generally, 1-2 can be used;

Because the test results are to be printed, a print interface is required;

Because the device needs to be debugged, parameter settings, display results, etc., the VGA interface and PS2 interface (separate) are required;

Because it is necessary to connect some PLC control devices, the COM port is also necessary;

Because if an abnormality is found during the test, it is required to promptly report the alarm, so the motherboard must bring its own buzzer, and the detection program generally uses this buzzer;

The main control system must complete the functions of information collection, processing, analysis, transmission and communication. The CPU performance should not be too low, but it is generally not required to be too high.

System specification:

Equipment for detecting the surface quality of PCBs (such as surface defects, open circuits and short circuits), used for quality inspection of semi-finished products in the production process, is a key technology for high-precision single-layer printed boards, especially multi-layer printed board processing. The test system integrates optics, precision mechanics, recognition 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 the industrial computer for processing, and then compares it with the standard data in the database to find defects on the PCB, and displays or identifies it with a display or an automatic identification system. Defects for repair by maintenance personnel.
