Abstract
This paper presented the technical process of the robot roll hemming which was used for the automobile industry. Hemming is the metalworking process in which the edge of outer panel is rolled over onto the inner panel. Although the process of hemming has developed fast, the study of it lack of relevant research, indeterminate numbers of bending, bending angle and pressure. When a 6-axis multi-joint robot is used, the bending trajectory becomes complicated since it can be moved in all three directions. In this study, we propose a system for the position coordinate and acceleration through double integration, and an acceleration sensor is mounted on the tip of the robot. In the further study, we need to improve the accuracy of the acceleration sensor and accurately locate the position coordinates.
