Development and Implementation of Robot Technology for High-Precision Positioning

This study, focuses on the development of robotic technology with an emphasis on high-precision positioning. It is specifically designed for the manual wiring production line of electronic connectors, catering to the demand for customized, small-quantity products. The approach involves integrating advanced image recognition technologies to significantly enhance precision in the production process. Experimental outcomes have highlighted the effectiveness of these methods, with the robotic arm achieving a positioning accuracy of up to
$\pm 10\mu\mathrm{m}$
. Given the dimensions of the plastic component holes, approximately
$600\ \mu\mathrm{m}$
in length and
$150\ \mu\mathrm{m}$
in width, a dual-lens system was essential for precise identification and positioning. This study employs a high-resolution camera with 10 million pixels mounted on the robotic arm, the image positioning technique utilizes pixel errors between the center hole and the positioning hole in the image to control minor movements of the robotic arm. When correcting the robotic arm, it is not influenced by the repeated accuracy of collaborative robots, thereby achieving a positioning accuracy of ±0.01 mm. This advancement in precise positioning technology, facilitated by image processing, has enabled the robotic arm to accurately align with the plastic component holes, thus simplifying the process of inserting terminals with remarkable accuracy.
