Method and equipment for bubble blowing and tube breaking in glass capillary tube

Abstract

The invention discloses a method and equipment for bubble blowing and tube breaking in a glass capillary tube. The equipment comprises a left end chuck assembly, a right end chuck assembly, a right end chuck body moving mechanism, a fire head assembly, a fire head moving mechanism, a capillary tube supporting block mechanism, a capillary tube scratching mechanism, a capillary tube breaking mechanism and a synchronous rotating mechanism capable of promoting the left end chuck assembly and the right end chuck assembly to rotate synchronously. The left end chuck assembly is used for clamping the capillary tube through contraction of sealing colloidal particles, and a rotating joint is arranged at the tail part of the left end chuck assembly so as to carry out air inlet bubbling on the clamped capillary tube. The right end chuck assembly clamps the capillary tube in the mode that an inner hole is contracted through a spring chuck. The capillary tube scratching mechanism comprises a capillary tube supporting block, a scratching driving mechanism and a capillary tube scratching blade connected with the transmission end of the scratching driving mechanism. According to the invention, automatic bubble blowing and pipe breaking processing can be realized, multiple groups can be arranged side by side for simultaneous processing, the production efficiency is improved, the labor intensity of workers is reduced, and the quality consistency is good.

Description

technical field [0001] The invention relates to a processing transition process for optical fiber joint fittings, which is a method and equipment for blowing bubbles in a glass capillary and breaking the tube, and belongs to the technical fields of optical fiber fitting processing and quartz glass processing. Background technique [0002] In the production process of optical fiber joints, the optical fiber should be inserted into the joint fittings. The joint fittings are glass capillary tubes with a hole diameter matching the outer diameter of the optical fiber, and the glass capillary tubes are drawn from large-diameter glass tubes. The dimensions are equal in diameter, and due to the small diameter of the optical fiber, it is difficult to manually insert it into a connector fitting with a matching bore. [0003] The current method is to chamfer the inner hole of the joint fittings. It is to manually seal one end of the capillary with a flame, inject a certain pressure gas...

Problems solved by technology

[0003] The current method is to chamfer the inner hole of the joint fittings. It is to manually seal one end of the capillary with a flame, pass a certain pressure gas into the capillary, heat the end with a flame and bubble, and then mechanically remove the bulb. Leave the tail of the bulb as the chamfer of the inner hole of the capillary to facilitate the penetration of the optical fiber. This method of processing the capillary is labor-intensive, low in production efficiency, and wastes a lot of materials
