With the rapid development of information technology, the demand for electronic components is increasing rapidly, and it is developing towards micro-refinement, intelligence and integration. The types and structures of electronic components are many and complex, and they need to go through multiple complex processes in the production process, which is prone to various problems, such as size inconsistency, surface defects, and unclear characters.

The qualification testing of electronic components requires a series of tests from many aspects, and with the continuous improvement of the industry's requirements for the quality of components, the accuracy, stability and efficiency of the testing equipment are particularly important. Traditional detection methods have been unable to meet the needs of high precision and flexible detection. Manufacturers gradually introduce visual inspection instead of manual to avoid wrong detection and leakage inspection, prevent products from bulge, damage, dislocation and other problems, improve shipping quality, enhance brand competitiveness.

Component visual inspection scheme

Scheme overview

The system includes: lens, camera, lighting, image capture card and software tools.

The CCD industrial camera is converted into an image signal, transmitted to a dedicated image processing system, and converted into a digital signal for feature extraction and judgment and automatic elimination of defective products.

Application scenario

① Detection of defects such as dimples, scratches and cracks on the surface of components.

② Detection of external coating loss and abrasion of components.

③ Electrode pin folding, bending detection, pin number, position detection, coating oxidation corrosion detection.

④ Component size and thread detection.

⑤ Model, specification, manufacturer, origin labeling, packaging and other testing.

Program advantage

It's fast. High precision. High accuracy. Long hours of continuous work. Non-contact detection, safer.

Visual inspection system through non-contact, non-damage real-time detection method instead of traditional detection, not only improve the intelligence and automation level of equipment, but also improve the production efficiency and quality of enterprises, and with the rapid development and iteration of semiconductor, electronic automation, optics and other technologies and continue to improve, is an essential means of detection in the future. At the beginning, it has shown a good momentum of development and many development directions, which is worth in-depth research and excavation of visual technology research and development companies.
