The role of visual inspection system in the production of components

Electronic components, as the upstream products of the electronic information industry chain, are the basis for the development of communications, computers and networks, digital audio and video systems and terminal products, and whether the electronic components work reliably determines whether the electronic equipment operates normally. The detection of appearance defects of electronic components is a very critical part, because these products are generally small. High quality requirements, it is difficult to pass a large number of manual inspection, the need to use electronic components visual inspection equipment to automatically detect appearance defects,vision system companies thereby improving the detection accuracy and speed, and reducing the damage that may be caused in the detection process.

Component automated inspection system analysis can get very good will be the following defects detected:

Mainly include:

1, character defects

Character blurring, offset, missing, error.

redundant, multiple characters.

2、Major surface defects detected.

Plastic sealing body incomplete, surface scratches, broken, etc.

3, Pin defect detection:

Pin spattering tin, tilted, skewed, burrs.

The feeding mechanism of the external network equipment will be measured components sent to the visual technology detection position, automatic visual inspection system to take pictures of the components to take the image, the image processing system to analyze these data signal problem of a variety of practical operations, the extraction of the characteristics of the target of the method, and finally we determine the components to be measured is OK or NG and send the corresponding results to the external environment equipment signal, to achieve the components size Measurement and design defect detection. The detection accuracy reaches 20 microns, and the detection development speed is less than 200ms. with China statistics related information, production and life status real-time display, convenient for real-time control of production and operation.
