A dancing wheel detection mechanism capable of variable tension adjustment and control

Abstract

A dancing wheel detection mechanism capable of variable tension adjustment and control, especially for the precise adjustment and control of variable tension during the layer-changing winding of optical fiber windings. It uses a stepping motor to drive the miniature ball screw transmission pair to make the position of the floating code change precisely in the length direction of the pendulum, and uses an angle sensor to detect the position of the pendulum, so that the pendulum remains in a horizontal position under the state of torque balance ;By changing the position of the floating code and the precise detection and control of the horizontal balance position of the swing rod, the tension of the optical fiber after layer-changing winding can reach a new stable value requirement, thus realizing the automatic adjustment and control of the variable tension of the optical fiber winding during layer-changing winding , which can eliminate the stress and strain difference between the inner and outer layers due to the increase in the number of layers of optical fiber windings, and finally realize the equal stress winding of the inner and outer layers of optical fiber windings, thereby significantly improving the signal transmission performance and stability of optical fiber windings.

Problems solved by technology

[0005] In order to overcome and make up for the large compressive stress of the inner winding of the optical fiber caused by the existing constant tension winding method of optical fiber, there is a large difference in stress and strain between the inner and outer layers of the winding, which greatly affects the signal transmission performance of the optical fiber winding and cannot meet the requirements of optical fiber winding. Due to the technical deficiencies and defects of winding stability requirements, the present invention provides a dancing wheel detection mechanism that can be adjusted and controlled by variable tension. Precise changes occur on the swing rod, and the angle sensor is used to detect the position of the swing rod, so that the swing rod can be kept in a horizontal position under the state of moment balance. The fiber tension after winding reaches a new stable value requirement, thus realizing the automatic adjustment and control of the variable tension when the fiber winding layer is wound.
