The method of claim 1, wherein the controller controls the servo motor (8) to drive the electrode (7) to rotate from an initial angle value to the target angle value according to the target angle value, and then stops the method, drives the electrode (7) to move along an axial direction thereof, and synchronously measures the angle of the electrode (7) in real time by using an angle measuring table to obtain an actual angle value, and uses a visual sensor to identify the actual angle value and feed back the actual angle value to the controller for comparison with the target angle value, if the actual angle value is different from the target angle value, the controller controls the rotation angle of the servo motor (8) until the actual angle value is the same as the target angle value.
