Problems solved by technology

[0005] In the prior art, some devices for heating and air suction have appeared in the field of fiber lasers on the market, but these two functions have not been combined, and the functions are relatively single, such as the device of the German 3SAE company, which heats the capillary glass tube It is integrated with the optical fiber cleaning function, but it can only realize the heating of the capillary glass tube, and cannot realize the heating of the capillary glass tube, and the suction is integrated, and because the heating time and temperature are uncontrollable, the fixture can only adapt to one specification of the capillary glass tube, making the capillary tube poor heating
Currently there is no device specifically for heated aspirating capillary glass tubes

Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as figure 1 and figure 2 As shown, it is a schematic diagram of the structure principle of the quartz capillary glass tube 16 in the specific application of the present invention, wherein the capillary glass tube 16 is a quartz tube with an inner diameter / outer diameter of 800 / 1000um high or low refractive index material. For other specifications, it is necessary to ensure that the outer diameter of the capillary glass tube 16 is used in conjunction with the heating fixture, otherwise the effect of heating and suction will be poor.

[0029] Such as image 3 and Figure 4 As shown, the capillary glass tube heating suction device of the present invention includes a suction assembly 1, a heating fixture 4, a temperature control switch 5, an air flow control switch 6, a device switch 7, a gas pipe 8, a start and end switch...

Abstract

The invention discloses a capillary glass tube heating and air suction device comprising an air suction assembly, a heating fixture, a switch assembly and an air pipe. A control system and a vacuum air pump are arranged in the air suction assembly. The air suction assembly is provided with a vacuum air pump air inlet hole and a vacuum air pump air outlet hole, the vacuum air pump air inlet hole isused for connecting the air pipe with a capillary glass tube, and the heating fixture is used for clamping the capillary glass tube. The capillary glass tube heating and air suction device has the advantages of being simple in structure, simple and convenient to operate and good in use effect.

Description

technical field [0001] The invention mainly relates to the technical field of optical fiber lasers, in particular to a capillary glass tube heating and suction device suitable for manufacturing an optical fiber combiner by the casing method. Background technique [0002] Fiber laser has the advantages of high conversion efficiency, good beam quality, convenient thermal management and compact structure. It has been developed rapidly in recent years and has been widely used in industrial manufacturing, biomedicine, national defense and security. With the needs of national defense, industrial processing and other industries, fiber lasers with higher power and beam quality have become the development direction of fiber lasers. In the development of high-power fiber lasers, the fiber pump coupler is one of the core components. Fused tapering is the main form of realization of optical fiber pump coupler. Its manufacturing process is to tightly combine multiple optical fibers into...
