Outline
Based on the technologies of vision detection, Automated Guided Vehicle (AGV) transmission, industrial robot intelligent grasping and automatic tightening, the automatic assembly efficiency, assembly quality and flexibility of welding and adjusting door cover have been greatly improved. The multi-channel cameras were integrated on the grab, and the key feature points were identified and extracted by taking photos of the door cover and the body-in-white, and the clearance and difference of each position between the door cover and the body-in-white were calculated, and then the clearance and difference matching algorithm was adopted to calculate the best position of the door cover relative to the body in white, then the transfer robot was guided to grab the door cover to reach the best assembly position. The door cover was tightened automatically by the tightening robot carrying the tightening shaft. The door cover automatic assembly technology not only improves the assembly efficiency and quality, but also reduces the labor load and cost, and ensures the overall appearance quality of the body-in-white.
