Abstract

The invention provides a sapphire crystal growth lifting device. The sapphire crystal growth lifting device is characterized in that a seed rod, a magnetic fluid sealing device, a bearing seat, a weighing sensor and a cross-shaped guide rail are included; the seed rod and the magnetic fluid sealing device are connected to the lower end of the weighing sensor through the bearing seat, the magnetic fluid sealing device is fixedly connected with the bearing seat, the seed rod penetrates through the magnetic fluid sealing device and the bearing seat, the cross-shaped guide rail is connected with the bearing seat, and the seed rod can be regulated in the X direction and the Y direction by regulating the cross-shaped guide rail. The movement precision of the seed rod can be effectively improved through the cross-shaped guide rail and the magnetic fluid sealing device, and then the product quality is improved.

Description

[0001] technology field [0002] The invention relates to a sapphire crystal growth and pulling device. Background technique [0003] In the current sapphire production device, the seal between the seed rod and other structures is sealed by an O-ring. The O-ring is easy to wear, and the matching precision of the two structures is not enough, resulting in low precision of the produced product. Contents of the invention [0004] The main purpose of the present invention is to provide a sapphire crystal growth and pulling device to solve the above problems. [0005] In order to achieve the above object, the technical solution adopted in the present invention is: a sapphire crystal growth and pulling device includes a seed rod, a magnetic fluid sealing device, a bearing seat, a load cell, a cross guide rail, a seed rod, and a magnetic fluid sealing device. The bearing seat is connected to the lower end of the load cell, the magnetic fluid sealing device is fixedly connected wi...
