The dispensing path of conventional dispensing devices is generated by manually teaching and array inputs. However, that approach has complex operation and does not account for the height difference of each workpiece, which lead to the result that the dispensing accuracy, production efficiency and dispensing qualify can not reach the desired level. In order to compensate for the defects, proposes an automated dispensing system that fusing cameras and laser sensors information to locate the position of dispensing. Firstly, make image template and teach dispensing path, and calculate the pose of target workpiece by template matching based on NCC. Then use laser sensor to measure the dispensing plane height of target workpiece. Finally, dispensing path is obtained by coordinate transformation in the three-axis dispensing platform. Experimental results show that both speed and accuracy of the system are good enough to meet the practical application requirement. In addition, the proposed method can also be applied to the workpiece of different height with the consistent dispensing effect.
