Abstract
In this paper, we propose a solution to upgrade the soldering line for antenna Midrange products on cars at the Premo Vietnam factory, in which, the manual solder joint quality inspection task will be completely replaced by an automated inspection system incooperating with an image processing technique. First, the mechanical structure design and equipment selection for the system are presented. Next, the image processing algorithm for solder joint quality inspection using NI Vision Builder software was proposed. In addition, a convenient user interface (UI) for monitoring and statistics is developed. The designed system has been integrated into the current product line. The experimental results show that the system operates stably, the solder joint quality is inspected and classified accurately, and the inspection time is shortened to only 1/8 compared to before.
