Inspection principle

For the upstream products of the electronic information industry chain, in order to ensure the quality of the products assembled by a fully automatic electronic product assembly production line, whether the electronic components work reliably determines whether the electronic equipment operates normally. Detection and monitoring are distributed in almost every part of the production line. In a process, because the appearance defect detection of electronic components is a very critical part. Because such products are generally relatively small and have high quality requirements, it is difficult to pass manual mass inspection. It is necessary to use electronic component visual inspection equipment for automatic inspection of appearance defects.

The advantages of machine vision are obvious. Compared with the human eye, the machine is not only not tired, but also has the consistency and repeatability that the human eye does not have. Moreover, the machine can see (and use) other light source information than visible light.

Inspection details

The visual inspection equipment for electronic components developed and produced by KEYE TECH uses machine vision to replace the human eye, converts the captured target into an image signal through a CCD industrial camera, and transmits it to a dedicated image processing system. Digitized signals; the image system performs various operations on these signals to extract the characteristics of the target, and then controls the on-site equipment actions according to the results of the discrimination. The equipment realizes the automatic process of component size measurement and appearance defect detection, automatic feeding, automatic detection, automatic sorting, automatic unloading, and automatic rejection of defective products.

Application range

• Connector appearance inspection: measurement of PIN diameter, PIN distance and other dimensions.
• Capacitor appearance inspection: capacitor size, pin diameter, etc.
• Inductor appearance inspection: measure length, width and other dimensions to detect surface defects.
• Appearance inspection of resistors: scratches, cracks, scorch, dimension measurement, etc.
• PIN needle appearance inspection: PIN needle spacing, offset, shortage, etc.
• Transformer appearance inspection: measure PIN diameter, PIN distance, row distance and other dimensions, and detect appearance defects such as desoldering, scorching, and poor pins.
• Wafer size and appearance defect detection: Wafer size measurement, accuracy ±0.001mm, wafer positive and negative coaxiality detection.

Advantage of system
