AOI Machine Automated Optical Inspection Systems Used In Electronics PCB

Product Background

PCB board visual inspection is mainly to find out the defects of electronic components and printed circuits by visually inspecting the characteristics of electronic components, which can help you more easily detect the problem of incorrect gaps between conductors. At the same time, visual inspection is generally used in production. The early stage of the process allows everyone to find defects and repair them in the early stage of production as much as possible to ensure a high product qualification rate. With the development and progress of modern industry, traditional detection methods can no longer fully meet the requirements of modern industrial production. For the measurement requirements of mechanical parts, real-time, online, non-contact detection, high-speed, and high-accuracy detection modes are the characteristics of the current manufacturing industry.

Inspection principle&features

PCB circuit board AOI inspection equipment, based on optical principles, uses image analysis to denoise, enhance, binarize and other processing of images, and uses deep learning and automatic control technology to comprehensively detect and process defects encountered in production, and generate real-time generation Test Report. Detectable items: mainly detect PCB scratches, exposed copper, dirt, poor dyeing, and integrity detection of solder joints and wrong orientation.

The detection process is as follows: after the product is in place, the client device gives a trigger signal, the industrial camera completes image acquisition, and the PCB board component intelligent visual inspection system detects the detection content (component (plug-in) mixing detection, whether there is a component (plug-in) or not). Detection, component (plug-in) positive and negative detection, component (plug-in) color detection, component (plug-in) direction detection, wire color detection, terminal block color detection, terminal block direction detection) for efficient analysis and processing. And the processed results, output OK/NG results to the client designated terminal, the overall detection results are as follows.

Machining Process

The mechanical part is the core component of the system, which carries all the transmission devices and electronic hardware (industrial cameras, light sources, industrial computers, touch screens, electrical boxes, etc.). The conveyor is controlled by a servo motor, and the image capture is accurate. The equipment is equipped with two defective product inlets to separate serious defective products (such as drum bottom, oblique leather tip, etc.) and general defective products.
