Problems solved by technology
[0002] With the rapid development of the electronic information industry, the number of components integrated into the PCB board (printed circuit board) is increasing, and the density is also increasing. Once the components have problems such as errors, reverse insertion, and missing insertion, The entire PCB board will be unusable, and in severe cases, it may even cause equipment damage, which will greatly affect product safety and production efficiency
[0003] At present, there are two methods for printed circuit board inspection on the market: one is manual inspection, and the installation of components is judged by human eyes. A complex PCB board takes a lot of time, is inefficient, and is prone to missed and false inspections. ; The other is automatic optical inspection equipment based on solder joint quality inspection, which has a low detection accuracy for components on the surface of the PCB and is difficult to precisely locate problem areas

The invention provides a real-time detection system for a PCB (Printed Circuit Board) surface component, comprising a PCB transmission belt, an infrared sensor, a camera, an industrial personal computer, a relay and alarm equipment, wherein the infrared sensor is configured to detect a PCB on the PCB transmission belt and send a detection signal to the industrial personal computer; the industrialpersonal computer is configured to control the PCB transmission belt to stop transmission based on the detection signal, send an instruction of acquiring PCB images to the camera, receive and processacquired image information, display that there is a problem on the PCB surface component in response to a processing result, and control the alarm equipment to perform alarm through the relay. In comparison with a traditional detection mode, the real-time detection system of the invention has the advantages of accurate fault positioning precision, high detection efficiency, real-time alarm and thelike, thereby realizing high-efficiency detection of the PCB.
Description
technical field [0001] The invention relates to the field of detection of electronic components, and more particularly, to a real-time detection system for PCB surface components.
