Abstract

A dynamic correction system of a manufacturing process using wire is provided. The dynamic correction system includes a driving device, a path sensor, and a controller. The driving device is configured to: drive a carrier with a motion parameter and encapsulate the carrier with a wire. The path sensor is configured to obtain an actual path information of the wire encapsulating the carrier. The controller is configured to: obtain an actual path of the wire encapsulating the carrier according to the actual path information; obtain an actual path difference between a target path and the actual path; determine whether the actual path difference is greater than a predetermined error; and, when the actual path difference is greater than the predetermined error, control the driving device to change the motion parameter to cause the actual path of the wire encapsulating the carrier to approach the target path.
