Abstract

The invention relates to a tension controller suitable for an active / passive wire feeding mode and a control method thereof. The tension controller comprises a base plate and a tension setting controller, wherein a tension wire wheel and a tension adjusting mechanism are arranged on the base plate. The tension controller suitable for the active / passive wire feeding mode is characterized by that the tension controller further comprises a servo motor and a tension sensor, wherein the servo motor is correspondingly provided with a PID controller; a rotating shaft of the tension wire wheel is in transmission connection with an output shaft of the servo motor; a signal output end of the tension sensor is electrically connected with a signal input end of a servo motor driving controller; a tension threshold value is preset by the tension setting controller; when a real-time tension value acquired by the tension sensor is greater than or equal to the tension threshold value, the servo motor driving controller controls the servo motor to work in a torque control mode; and when the real-time tension value acquired by the tension sensor is less than or equal to the tension threshold value, the servo motor driving controller controls the servo motor to work in a speed mode.

Description

technical field [0001] The invention relates to a tensioner for a winding process, in particular to a set-type tension control method based on the application of a torque servo motor. Background technique [0002] At present, tension controllers are needed in winding processes such as motor rotation, stator manufacturing, small transformers, and relay coils. The coil is suitable for tightness and tightness. [0003] The setting type tension control system is to install a tension preset control circuit on the general-purpose electronic control tension control system, and change the manual tension adjustment to directly input the tension parameters to the tension control system, which is more intelligent. [0004] But no matter what kind of tension controller is divided into two categories: active wire feeding type and passive wire feeding type according to the wire feeding method. [0005] The outstanding advantage of the active wire feeding type is that the control precisi...
