Abstract

The invention relates to a preparation method and a device for reaming holes on the end of a capillary glass tube. The preparation method comprises the following steps: a. preparation of inclusions containing capillary glass tube matrix: distributing capillary glass tube arrays with consistent inner diameter, outer diameter and length and flat cutting surfaces, and wrapping the length direction with acid-proof organic matters; b. oriented corrosion for end surfaces of inclusions: controlling the concentration, temperature and corrosion time of hydrofluoric acid to produce a capillary glass tube blank with a horn mouth in a horizontal height controlling mode or a vertical soaking mode; c. end grinding: carrying out end grinding on the capillary glass tube with the horn mouth so as to remove the part of the outer diameter, which is exceeded by the maximum outer diameter of the corroded area and the outer end of the horn mouth. According to the preparation method and device, the key technology that the capillary glass tube is difficult to ream holes by adopting a two-step method can be solved, and the horn mouth which is excellent in geometric shape consistency, free from obvious residual stress, easy for optical fiber to penetrate, and easy for glue to wet can be realized.

Description

technical field [0001] The invention relates to a batch processing preparation technology of flaring the ends of glass capillary tubes by utilizing the siphon principle and hydrofluoric acid corrosion process. The obtained glass capillary tube products with bell-mouthed inner holes at the ends are mainly used for connecting and fixing optical fiber optical communication radios. A source / active device belongs to the field of glass material processing. Background technique [0002] Optical fiber communication widely requires precise positioning and connection of optical fiber and optical waveguide devices to realize the transmission of optical signals of passive devices and active devices in the optical fiber medium. Ceramic ferrules made of zirconia and capillaries made of high borosilicate glass or quartz glass (hereinafter referred to as glass capillaries) are the main functional materials used in all-optical network fiber connection technology. The structure of glass capil...
