Electronic product appearance defect detection scheme and equipment application

Date：2022-01-12 13:30:00Views：1182

The appearance defect detection of electronic components is a very key link. Because such products are generally small and have high requirements for quality, it is difficult to pass the manual mass detection. It is necessary to use the visual detection equipment of electronic components for automatic appearance defect detection. The appearance equipment detection method can detect defects in real time, quickly and accurately identify scratches, greatly improve the production efficiency of the production line and improve the production quality of products.

Inspection cases of appearance defects of electronic products

Connector appearance inspection: measurement of pin diameter, pin distance and other dimensions.

Appearance inspection of capacitor: capacitor outline dimension, pin diameter dimension, etc.

Appearance inspection of inductor: measure length, width and other dimensions, and detect surface defects.

Appearance inspection of resistor: scars, cracks, charring, size measurement, etc.

Pin appearance inspection: pin pin spacing, offset, shortage, etc.

Transformer appearance inspection: measure the pin diameter, pin spacing, row spacing and other dimensions, and detect the appearance defects such as desoldering, scorching and poor pins.

Wafer size and appearance defect detection: wafer size measurement, accuracy ± 0.001mm, wafer forward and reverse coaxiality detection.

Application of appearance defect detection equipment：

1. Application in automobile safety

Compared with the vast majority of people, they still rely on subjective thoughts and consciousness to judge emergencies in the whole process of driving. With the frequent and frequent occurrence of safety accidents, the safety concept has attracted much attention. Digitization is used in automobile safety monitoring system, which is also highly discussed in the industry.

2. Application in printing industry

Use online / offline visual defect detection system software to detect product quality problems in the whole printing process,

3. Application in PCB inspection

The visual defect detection system is used to control the PCB bare board for inspection. The specific position and spacing distance of wires and components on the board are wrong, the overall dimension of lines and components is wrong, the shape of components is wrong, the on-off of lines, the contamination on the board, etc.

4. Application in parts inspection

Defect detection equipment can more effectively solve the quality control of metal parts production, such as coins, auto parts, connectors, etc. According to the way of image processing, the defects such as scratch, deformity, discoloration and mucous membrane on the surface of metal parts are found, and the mechanical transmission system software is professionally guided to remove the defective products, which further improves the production efficiency. At the same time, the statistical analysis of defect types can professionally guide the adjustment of production parameters and improve product quality.
