[0002] China's spallation neutron source detectors include scintillator detectors. Existing scintillator detectors need to use wave-shifting optical fibers for detector signal transmission. Wave-shifting optical fibers are very expensive. Most of them are imported at present, and the price is 17 US dollars. / m, the structure of the wave-shifting fiber is brittle, and it is easy to be bent and damaged, and thus light leakage occurs, which affects signal transmission; during the development of the detector, it is necessary to realize the 90-degree bending of the wave-shifting fiber, in order to realize the 90-degree bending of the fiber Bending, designed a bracket for optical fiber bending, including a plate and a bending plate that is hinged at both ends of the plate and can only be rotated 90 degrees. There is a fiber groove on the plate and a pressing device on the bending plate. In the process of wave-shifting optical fiber water bath bending, it is difficult to control the speed, strength and time of each bending by manual bending, and the degree of each bending is different, so that the consistency of optical fiber water bath bending is difficult. Guaranteed, it is difficult to avoid accidental errors, and sometimes the optical fiber will break due to poor control of the force, resulting in the waste of expensive wave-shifting optical fiber
