Quartz ampoule bottle sealing device and method

Abstract

The invention belongs to the technical field of chalcogenide glass production, discloses a quartz ampoule bottle sealing device and method and mainly solves problems of low sealing quality, high laborintensity and low efficiency in manual sealing. The quartz ampoule bottle sealing device comprises a body, a combustion unit, a clamping unit, a vacuum unit and a control unit. The combustion unit mainly comprises a translation mechanism and a burning gun; the clamping unit comprises a tray, a rotating shaft, arc clamping plates, a clamping plate radial adjustment mechanism and a rotating and lifting mechanism, and tray is capable of clamping a quartz ampoule bottle to rotate and move up and down; the vacuum unit mainly comprises a vacuum molecular pump, a vacuum gauge and a vacuum rotating joint. In an ampoule bottle sealing process, the control unit performs burning gun translation and tray lifting interpolation control according to inputted bottle plug size data, and sealing is realized by flame core in spiral ascending relative to a bottleneck; after sealing is finished, bottleneck closing treatment is performed, and excessive parts are removed, so that subsequent space occupationof melting equipment is reduced.

Description

technical field [0001] The invention belongs to the technical field of chalcogenide glass production, and specifically relates to a quartz ampoule fusion sealing device and method, which are used for sealing the quartz ampoule filled with chalcogenide glass mixture before the melting process. Background technique [0002] Chalcogenide glass is a special optical material with infrared transmission properties. Due to its good infrared optical properties and easy processing, it has been widely used in night vision and security fields. Chalcogenide glass is usually prepared by the quartz ampoule method, that is, the purified mixture is placed in a quartz ampoule, the ampoule is evacuated and sealed, then placed in a swing furnace, melted at high temperature according to a special process, and then After quenching and annealing, it is finally made into chalcogenide glass with specific components and specifications. The fusion sealing of ampoules is an important link in the prepa...

AI Technical Summary

Problems solved by technology

The advantages of manual fusion sealing are low cost, simple operation, and strong adaptability to ampoules of different shapes and specifications. The disadvantages are unstable sealing quality, high labor intensity, and low efficiency.

[0004] The Chinese patent with the publication number CN103332854B discloses a hydrogen-oxygen torch sealing machine, and proposes a device and method for automatically sealing a quartz glass tube (similar to the quartz ampoule described in the present invention), but due to the use of The three burning guns rotating in the circumferential direction are more complex in structure. At the same time, the position of the flame core is relatively fixed during sealing. In this case, it is necessary to manually adjust the height of the burner frequently, and after the sealing is completed, it cannot be closed along the top of the sealing position like a manual operation, so that the excess part above the bottleneck can be removed before being put into the swing furnace for melting. , reducing the space requirement for the rocking furnace chamber
