Problems solved by technology

However, the volume of the device is large due to the up-and-down structural relationship between the drum, the base and the traction device at the lower end of the base; at the same time, the drum and the traction shaft are connected by a chain gear, and there are often gaps in the linkage process between the chain and the gear, which affects the Accuracy when controlling the pulling speed; on the other hand, during the use of the device, the drum, base and motor are simultaneously pulled by the traction device to produce displacement, so the traction device is under a lot of force, which makes the traction device easy to wear. affected the service life

Abstract

The related crystal lifting device comprises a coil wheel with winding tow steel cable, a coaxial gear shaft to rotated support on the supporting body, and a lifting assembly composed by dynamic mechanism to drive the shaft and wheel. Wherein, fixed connecting the tow wheel and coil wheel together on the shaft with at least one slide connecting by spline; connecting tow wheel and tow sleeve by screw with axial displacement determined by screw pitch. This invention can ensure cable and speed stability, and prolongs service time.

Description

technical field [0001] The invention relates to a crystal lifting device, in particular to a crystal lifting device for a single crystal furnace. Background technique [0002] When producing single crystal silicon, the crystal lifting device is used to lift the seed crystal in the single crystal furnace to realize the growth of single crystal silicon. In this process, the seed crystal must be rotated while being lifted, and its lifting speed and rotation speed must be strictly controlled in order to achieve the expected production purpose. At the same time, in practical application, the crystal lifting device must meet the requirements of stable lifting speed and good neutrality of the wire rope. The existing crystal lifting devices all use the winding wheel to rotate and wind the wire rope to move the seed crystal up and down. During the process of winding the wire rope with the winding wheel, the wire rope is easy to shift and stack, which affects the stability and speed ...
