Briefly describe the application of machine vision system in solder joint inspection

 The application of machine vision system in solder joint inspection can detect defects such as solder joint alignment, spacing, solder ball size, solder ball brightness, ball upturn, and surface foreign matter (plastic wire, etc.). The system adopts assembly line operation, using a monochrome black-and-white CCD system and a single-channel image acquisition card. The lighting uses dual light sources to illuminate and image at once, which can not only effectively highlight all foreign body defects on the plastic surface, but also highlight all the surface information of the solder ball. The lens selection The megapixel CCD lens can produce clear images and reduce the adverse effects caused by lens distortion. The entire system is fully automated and can be operated by no one. The detection and positioning software uses relevant tools to analyze and process the image. The detection speed is very fast, and basically all foreign objects and defective solder balls can be picked out.
The machine vision welding inspection system has great technical advantages: it can be specially designed for triode automatic welding machines; the welding speed is more than ten times that of the old manual welding machines; the welding accuracy is high; the system is stable and rarely malfunctions; it is easy to operate and install Simple; rich machine debugging and diagnostic functions; ensuring quick return on investment; the page can be used for the modification of old manual triode welding machines.
Machine vision systems have great development potential. Based on this application, they will be more stable and can open up other application areas and provide the industrial production safety required in the future. High-performance machine vision systems are linked with various industries to pursue excellence and promote industry development.
