Inspection principle
Printed Circuit Board (PCB for short) is an indispensable basic component of electronic information products. PCB is also known as the "mother of electronic products". It is an important electronic component and a support for electronic components. , is the carrier for the electrical interconnection of electronic components. The development level of the PCB board industry can reflect the development speed and technical level of the electronic information industry of a country or region to a certain extent.
Usually, character information such as product materials, production information, and product technology will be printed on the PCB board. However, in the actual character printing process, there will be defects such as missing characters, missing characters, and different character specifications. In the PCB production line, if the traditional manual inspection method is used, the PCB board inspection efficiency will be low, and the printed characters will be missed, misjudged, and the inspection standards will not be uniform.
Inspection details
In the process of PCB board testing, if the manual testing method is adopted, the testing personnel usually need to monitor 8-10 test equipments at the same time, which is easy to cause fatigue of the testing personnel. Since the human eye cannot detect millisecond-level flashing faults, these problems will lead to low testing efficiency. , the detection accuracy is not high. In the process of PCB board production, it is necessary to test the plug-ins on the PCB board before the furnace, and test the back cover and the outer door. It is also difficult to meet the detection requirements by manual detection. It is necessary to use a high-resolution industrial camera to capture the circuit board in real time. image information.
KEYE TECH's OCR industrial visual inspection solution can perform fast, accurate and efficient identification and inspection of printed characters on PCB boards, plug-ins, back covers, and appearance of boards, which can reduce inspection personnel, save inspection costs, and improve inspection. efficiency.
Advantages of system
The heuristic mechanism specially designed for character recognition can simulate the thinking mode of the human brain to evaluate the rationality of the features extracted by the attention model, so that the attention model has strong adaptability in complex scenes and significantly improves the character recognition rate.
Collect the image information of the PCB board through high-resolution equipment such as industrial cameras and zoom lenses, and then complete the identification and processing of the image information through the AI intelligent platform. It can automatically learn through standard template pictures, and perform comparison processing according to the learned pictures; for character recognition such as letters and numbers, it is necessary to train the standard character library in advance, and the training can be completed with one click.
Features of system
- Improve inspection quality: use deep learning algorithm as the analysis core, and use AI intelligent platform to improve the detection accuracy of PCB boards.
- Improve detection efficiency: multiple components can be tested at the same time by using a single channel of video, 7*24 hours of continuous testing, which significantly improves detection efficiency;
- Reduce testing costs: realize automatic testing of PCB boards, completely release testing personnel, and reduce labor testing costs for enterprises.
