After the battery is stacked, the stacked batteries need to be welded together with two end plates and side plates to form a whole module.By visually positioning the position and angle of the welding seam of the side plate, the robot is guided to weld. The positioning accuracy is required to be 0.1mm.
The robot hand and the camera are calibrated to establish a coordinate correspondence relationship. The camera takes pictures to locate the position and angle of the weld. The starting point of the weld and the welding direction are obtained by calculation.
