Description
Technical Field
The invention relates to a sapphire window production process, in particular to a sapphire window assembly production process.
Background
Sapphire is a general term for corundum of other colors than Ruby, and the main component of sapphire is alumina (Al)2O3). Blue sapphire, due to the small amount of titanium (Ti) and iron (Fe) impurities mixed therein. The color of the sapphire can be pink, yellow, green and white, and even the sapphire has various colors in the same stone, and the sapphire has the biggest characteristic of uneven color, and can see straight color bands and growth lines which are arranged in parallel hexagonal cylinders and have different depths. The growth of poly-lamellar twins, often with louvered twinned striations. Cleavage is mostly along the double crystal planes. The dichroism is strong, and the sapphires in different producing areas in the world have the common characteristics and the characteristics due to different producing areas, and the sapphires are high in hardness, resistant to scratching, rubbing and grinding, high in transparency, good in light transmission and high in light emitting efficiency, so that the sapphires are applied to various industry fields.
However, most sapphire window production processes in the market are single, the operation is complex, the quality effect of the produced sapphire window assembly is poor due to the fact that the traditional sapphire window assembly is produced indoors and a large amount of dust is contained in the air, and the later-stage use of the sapphire window assembly is affected.
Disclosure of Invention
The invention aims to solve the defects in the prior art and provides a sapphire window assembly production process.
In order to achieve the purpose, the invention provides the following technical scheme: a sapphire window assembly production process comprises the following steps:
s1, manufacturing a stamping die according to the inner diameter size of the Kovar washer, namely 31.6mm and the effective depth of the Kovar washer, stamping pure lithium into phi 31.6mm H and 2.8mm pure lithium sheets for later use;
s2, placing the sapphire window, the gasket, the lithium sheet and the mold into a glove box;
s3, pressing the lithium sheet into the kovar washer by using a die, wherein the lithium sheet is required to be flat without overflow, and the effective thickness is 2.8 mm;
s4, positioning by using a mould, pressing the B4C into the central position of the lithium sheet without bulge, and keeping the lithium sheet at a horizontal plane;
s5, taking out the gasket, horizontally putting the gasket into the sapphire windows without inclination, clamping the other sapphire window, ensuring that the two sapphire windows and the gasket are horizontally clamped, and ensuring that the edge gap of the two sapphire windows is not more than 0.05 mm;
s6, placing the assembled sapphire window into a laser welding tool room for laser welding;
s7, carrying out vacuum-pumping experiment on the welded assembly, wherein the air tightness is required to be more than or equal to 1 x 10-8Pa.m3/s；
S8, filling argon into the sapphire window assembly in a glove box, packaging the sapphire window assembly by using an aluminum foil bag, and taking out the sapphire window assembly;
and S9, finishing all the processes, delivering goods and waiting for customer detection.
Preferably, all the above process steps are performed in a vacuum glove box under an argon atmosphere at normal temperature.
Preferably, the appearance and quality are checked at 100% to distinguish whether the product is good or bad.
The invention has the technical effects and advantages that:
1. according to the invention, all process steps are finished in the vacuum glove box and under the argon protection environment at normal temperature, so that the environment cleanliness during the production of the sapphire window assembly can be ensured, the influence of dust in the air on the quality of the sapphire window assembly can be effectively avoided, and the production quality of the sapphire window assembly is effectively enhanced.
