[0002] The elevator door pulley is a key component in the elevator door system. It is mainly used to suspend the elevator door body and bear the weight of the elevator door body. The door body is suspended on the track so that the door body contacts the track only through the pulley, reducing friction resistance. Through the cooperation between the wheel body and the track, the door body is guided to move in a fixed direction, ensuring smooth and smooth opening and closing of the door. When processing the elevator door pulley, the center of its outer cylindrical surface needs to be turned. During processing, manual loading and unloading is often used, which is time-consuming and labor-intensive. If a robot is used for loading, a multi-axis control robot is required. Then, when the multi-axis control robot is in operation, it is necessary to control intermittent loading, material clamping and intermittent unloading.
