Micron-scale concentricity detector and detection method thereof

Abstract

The invention relates to a micron-scale concentricity detector and a detection method thereof. The detector comprises a horizontal rotating mechanism, a gauge clamp and a dial gauge. The horizontal rotating mechanism comprises a bottom plate, a bearing seat and a rotating shaft; the rotating shaft is rotationally connected to the bearing seat through a bearing; two ends of the rotating shaft extend out of the bearing seat; one end of the rotating shaft is connected with a rotating handle; a connecting sleeve is inserted into the other end; a first ceramic ferrule is inserted into the connecting sleeve; one end, far away from the connecting sleeve, of the first ceramic ferrule is connected with the optical fiber adapter; the gauge clamp is connected to the bearing seat; and the meter clampis provided with a meter clamping hole and a clamping screw corresponding to the meter clamping hole. The gauge rod of the dial gauge passes through the gauge clamping hole and is locked by the clamping screw; the head of the dial gauge is perpendicular to the axial direction of the rotating shaft, the head of the dial gauge is contacted with the periphery of the front cover of the optical fiber adapter, the rotating shaft rotates for a circle, the concentricity of the front cover of the optical fiber adapter and the ceramic ferrule in the optical fiber adapter is calculated according to the height change of the dial gauge, and the detection precision and efficiency are high.

Description

technical field [0001] The invention belongs to the technical field of optical fiber adapter concentricity detection devices, and in particular relates to a micron-level concentricity detector and a detection method thereof. Background technique [0002] With the rapid development of 5G communication, the performance requirements for its equipment are getting higher and higher, and the concentricity requirements for the ceramic ferrule of the fiber optic adapter and the front cover are also getting higher and higher, so as to meet the requirements of the two optical fibers at 9 μm. More demanding docking within the radius, lower loss in optical transmission, and higher pass rate, so as to meet the transmission performance requirements of 5G high-bandwidth, the ceramic ferrule of the optical fiber adapter in the prior art has been embedded No reference point can be found inside the metal to position and calibrate it.

[0002] With the rapid development of 5G communication, the performance requirements for its equipment are getting higher and higher, and the concentricity requirements for the ceramic ferrule of the fiber optic adapter and the front cover are also getting higher and higher, so as to meet the requirements of the two optical fibers at 9 μm. More demanding docking within the radius, lower loss in optical transmission, and higher pass rate, so as to meet the transmission performance requirements of 5G high-bandwidth, the ceramic ferrule of the optical fiber adapter in the prior art has been embedded No reference point can be found inside the metal to position and calibrate it

It is more difficult to measure the concentricity of the ceramic ferrule and the outer diameter of the matching front cover, so that the concentricity requirements of the ceramic ferrule and the front cover cannot be guaranteed and tested, resulting in misalignment when the adapter is docked with the ceramic ferrule at the other end, resulting in The performance of the transmission is low, and a large amount of transmitted data is lost
