Optical fiber coupling proximity device

Abstract

The invention discloses an optical fiber coupling proximity device which is characterized in that the device includes four push mechanisms arranged correspondingly; each push mechanism includes a base, a drive cylinder installed on the base and a slide shaft capable of sliding on the base; the slide shaft is connected with the drive cylinder, and a push assembly is arranged on the slide shaft; each push assembly includes a connecting seat fixed to the end of the slide shaft; a slide rod capable of sliding in the connecting seat is arranged in the connecting seat; a push block is arranged at the end of the slide rod; a proximity slot into which an optical fiber can be embedded is arranged on one side of the push block; a reset spring capable of resetting the push block is arranged between the push block and the connecting seat; and under the drive of the drive cylinders, each push block and the corresponding push block press against each other to make optical fibers stay close and spaced apart at a certain distance.

Description

technical field [0001] The invention relates to an optical fiber coupling fusion taper machine, in particular to an optical fiber coupling proximity device on the fusion taper machine. Background technique [0002] Optical fiber coupler is an important part of optical fiber communication network. At present, the production method of domestic optical fiber coupler is mainly sintering method. The sintering method is to burn and stretch two or more optical fibers together to make the core Aggregate together to achieve optical coupling, and the most important production equipment is an optical fiber fusion tapered machine. [0003] The previous optical fiber fusion taper machine was used to manually twist the optical fiber to make two or more optical fibers entangled and contacted together in the production of optical fiber couplers, and then fixed the optical fibers with a clamp, and then sintered the entangled and contacted part of the optical fibers with a hydrogen-oxygen fla...

Problems solved by technology

[0003] The previous optical fiber fusion taper machine was used to manually twist the optical fiber to make two or more optical fibers entangled and contacted together in the production of optical fiber couplers, and then fixed the optical fibers with a clamp, and then sintered the entangled and contacted part of the optical fibers with a hydrogen-oxygen flame together, but manual stranding is not only low in efficiency and high in cost, but also difficult to guarantee the quality of sintering. Therefore, at present, someone has designed a fusion tapered automatic approaching device to realize the approaching and contacting of optical fibers, but the above-mentioned device needs to be coordinated with a CNC servo motor The guide rail screw drives the clamp to move to realize the accurate movement of the optical fiber, so that the optical fiber is close to and in contact, but the above-mentioned device not only requires high assembly accuracy but also is expensive, so it is necessary to improve
