Abstract: Abstract: Silver contact points are fixed on contact carriers by thermal welding. The two sides of a contact points are different for distinction: the working surface is smooth while the welded surface has striped or dotted texture. Aiming at the low efficiency of artificial feeding for silver contact points welding machine, an automatic feeding device was designed using machine vision technology. Firstly, the hardware platform of the machine vision system was built, and the suited camera、lens and illuminant were selected according to the characteristics of the silver contact. Secondly, the gray level co-occurrence matrix(GLCM) algorithm was used to identify the texture and non textured surface of the silver contact points. Then, on the hardware platform of the device, the operating user interface is developed by using the MFC framework and the industrial camera SDK. The experiments proves that the device is of quick speed, high accuracy and low cost.
