Swing type stable tension buffering method and device for carbon fiber prepreg tape

Abstract

The invention relates to a swing type stable tension buffering method and device for a carbon fiber prepreg tape. The swing type stable tension buffering device comprises a buffering motor and a buffering device main shaft, a swing rod and a micro clutch are arranged on an output shaft of the buffering motor in a sleeving manner, the swing rod is connected with the micro clutch, the two ends of the swing rod are respectively provided with swing rod guide wheels, and the prepreg tape is wound around the two swing rod guide wheels in a Z shape. According to the swing type stable tension buffering method and device, the swing rod is used as a buffer element, so that tension fluctuation caused by inertia of the buffer element in the buffer process is reduced; the micro clutch is adopted as a tension control element, a motor drives the clutch to transmit stable driving torque to the swing rod, the torque is balanced with the torque of the swing rod under the tension action of the prepreg tape, so that the prepreg tape keeps stable tension; and the tension value of the prepreg tape can be adjusted by controlling the output torque of the clutch, the tension value is stable and can be verysmall, and the stable tension of the prepreg tape can be maintained in the buffering process.

Description

technical field [0001] The invention relates to the field of automatic fiber laying tension control, in particular to a carbon fiber prepreg tape swinging type smooth tension buffering method and device, which eliminates the large fluctuation of prepreg tape tension during the buffering process caused by the reciprocating friction of the buffer element, and can During the buffering process, maintain a steady and small tension on the prepreg tape.
