Alignment technology is widely applied to industrial manufacturing, such as labeling, embossing, etc. With the improvement of automation technology, automatic alignment system gradually replaces manpower to enhance production efficiency and save manpower cost. In the past, automatic alignment system generally adopted mold alignment, and the method was mostly combined with mechanical components to achieve the positioning, such as positioning bead, positioning column, positioning pin and other components. However, there are limits to the contact alignment through mechanical components. Therefore, visual image assist can greatly improve the alignment precision. Next, we will use an implementation case to show how to apply visual image assist technology to precision alignment. 

Implementation Case

This implementation case is applied to object labeling. Its purpose aims to apply the label (film) precisely to the designated position of the pasted object (back shell of mobile phone) through the automatic system. It assists positioning through dual camera (hereinafter referred to as upper camera and lower camera), as detailed below.

The software and hardware specifications are shown as follows:

Hardware
