Abstract

The invention discloses a crystal furnace lid hoisting auxiliary tool. The crystal furnace lid hoisting auxiliary tool comprises a hoisting rod and a height adjusting device arranged on the hoisting rod. The height adjusting device comprises a rocking handle, a gear connected with the rocking handle and a screw rod engaged with the gear. One end of the hoisting rod is equipped with a first clamping mechanism connected with a crystal furnace elevating device. A cavity used for placing the screw rod is arranged inside the hoisting rod. One end of the screw rod is placed in the cavity. The other end of the screw rod is equipped with a second clamping mechanism used for hoisting a furnace lid. The crystal furnace lid hoisting auxiliary tool is simple in structure, is firm and reliable, is convenient to operate, solves the problem that a hoisting way for a present crystal furnace lid is unreasonable effectively, shortens production time greatly, and is labor-saving and time-saving.

Description

technical field [0001] The invention relates to the field of sapphire crystal processing and manufacturing, in particular to a lifting aid for a crystal furnace cover. Background technique [0002] The composition of sapphire is aluminum oxide (Al 2 o 3 ), is an important optoelectronic material, which has the characteristics of high hardness, wide transmission band, high thermal shock resistance and high strength, so it is widely used in machinery, electronics, optics, LED lighting, semiconductor devices, aerospace and military fields. Has a wide range of uses. In particular, the sapphire lattice structure matches gallium nitride, which is currently the most widely used and most mature LED substrate material. [0003] The preparation process of LED substrate materials includes three processes of sapphire crystal growth, sapphire ingot processing and sapphire wafer processing, forming three kinds of materials: ingot, ingot and wafer. Among them, the sapphire crystal grow...
