Embodiment Construction

[0036] Such as Figure 1~5 The shown optical fiber torsion recovery method is special in that it includes the following steps:

[0037] First, the optical fiber 12 is paid out from the fiber payout reel 4 of the fiber payout device, and the optical fiber 12 is connected to the fiber take-up reel 7 of the fiber take-up device. Then, the fiber payout device and the fiber collection device move toward the middle through the linear guide rail 1 until the optical fiber 12 is twisted due to natural sagging. In other words, along with the winding of the optical fiber 12 , when the fiber pay-off device and the fiber take-up device are close together, the optical fiber 12 will be twisted counterclockwise or the optical fiber 12 will be twisted clockwise.

[0038] In order to continue winding of the fiber, torsional recovery must be performed. Specifically, if the optical fiber 12 is twisted counterclockwise before, the fiber collection reel 7 is rotated clockwise, and the driving dev...

Abstract

The invention relates to an optical fiber twisting recovering method and device. In the method, when hanging optical fibers are overlapped and twisted, the winding direction can be adjusted till the overlap and twisting disappear. The adopted device is characterized in that: a fiber unwinding device and a fiber winding device are arranged on a linear guide rail in a sliding way; the fiber unwinding device comprises a main bracket connected with the linear guide rail; the main bracket is provided with a main driving shaft; one end of the main driving shaft is provided with a fiber unwinding disk, and the other end of the main driving shaft is provided with a driving device; simultaneously, the fiber unwinding device comprises a secondary bracket connected with the linear guide rail; the secondary bracket is provided with a rotating shaft; a rotary platform is erected on the rotating shaft, and is provided with a driven shaft; and one end of the driven shaft is provided with a fiber winding disk, and the other end of the driven shaft is provided with a driving device. Due to the adoption of the invention, operation can be performed by twisting the fiber unwinding device and the fiber winding device based on a horizontal plane, and the defect of breaking of an optical fiber, caused by gravity, is overcome.

Description

technical field [0001] The invention relates to an optical fiber torsion recovery method and its device, in particular to an optical fiber torsion recovery method and device for winding an optical fiber ring. Background technique [0002] Fiber optic angle sensor (also known as fiber optic gyroscope) is a new type of sensor that uses fiber optic sensing technology to measure the space inertial rotation rate. Compared with the previous mechanical gyroscope, it has the characteristics of no mechanical rotating parts and high sensitivity; Compared with laser gyro, it has advantages in technical indicators and environmental adaptability; compared with laser gyro, it does not require ultra-high-precision optical processing, does not require mechanical bias and high pressure, does not need to use high-performance gas seals, is easy to manufacture, easy to integrate, and has a long life Longer, the Fiber Optic Gyro is the only one of its kind that has no moving parts. It is widely...
