Inspection principle

With the gradual popularity and upgrading of electronic equipment, USB interfaces are widely used as data transmission and data lines in information communication products such as personal computers and mobile devices, and are extended to photographic equipment, digital TVs (set-top boxes), game consoles and others related field.

As an auxiliary product that is vital to electronic products, the market demand is large, but the uneven quality has caused dissatisfaction among many consumers. Many manufacturers are aware of such problems. However, there is no better solution to the problems of traditional manual quality inspection such as low efficiency and low accuracy. Based on the above situation, our company has developed an online visual inspection system for the USB interface. It fundamentally solves the problems of manual quality inspection, prevents the subjective problems of human detection of USB interfaces, and realizes fully automated online detection and removal of USB interfaces.

1. Adopt advanced image visual inspection technology to realize all-round inspection of the USB interface in motion state, identify defective products and realize automatic rejection.
2. Detection range: accurately detect the shape, model, color, machine line identification, stains, missing corners, curled edge, and other defects on the USB interface
3. Detection speed: 180-250 pieces per minute
4. Product features: A high-precision color camera is used for pixel-level detection of wear and scratches on the USB interface. The detection system independently developed by our company can realize different detection functions according to different products and requirements.
5. l The area threshold is above 0.5 mm² and can be adjusted.
6. l The detection accuracy is greater than 99.5%, and the false rejection rate is less than 2%

The system uses 4 high-definition industrial cameras to take pictures of the front and back of the USB ports on the A and B channels of the production line and display them in real time. The system uses deep learning AI technology to automatically learn the characteristics of the surface defects of the USB port, so as to realize rapid judgment, Real-time detection, real-time elimination and other functions. The system has the characteristics of high detection accuracy, low missed detection and low false detection rate. The software comes with statistics and defect picture storage functions, real-time monitoring of the operation of the production line, and timely detection of production line problems.

Test content:

(1) Shape: flat edge, curled edge

(2) USB interface color. (Interfaces of different colors have different functions)

(3) The machine line identification is not standardized;

Inspection environment:

It should be in a dry and ventilated workshop with a room temperature of -15°C to +30°C and a relative humidity of 50% to 80%, away from heat sources, and more than 20 cm away from the ground and walls. Avoid being affected by corrosive substances such as acid, alkali, oil, etc., do not place it in the open, avoid direct sunlight, and do not touch the ground.
