Description

Automatic crystal clamp

Technical Field

The utility model relates to an anchor clamps for getting crystal, concretely relates to automatic change crystal anchor clamps.

Background

Sapphire is a single crystal of alumina, also known as corundum. The sapphire crystal is used as a functional material with excellent optical property, mechanical property and chemical stability, and has the advantages of high strength, high hardness, high temperature resistance, corrosion resistance and the like. The high-temperature-resistant high-voltage LED high-voltage. The continuous improvement of the processing efficiency and the processing quality is pursued by the sapphire processing industry at present.

With the wider application range of sapphire materials, various sapphire manufacturers develop research work on large-size sapphire single crystals. However, as the size of the crystal increases, the larger the diameter of the crystal, the smaller the distance from the crucible wall, and the more difficult it becomes to take out the crystal. The traditional artificial crystal taking method is easy to crack the crystal due to improper force application in the clamping process, and the collision between the crystal and a crucible is easy to occur in the extraction process to generate dark cracks. It is therefore desirable to provide a simple, damage-free crystal holder.

Disclosure of Invention

The utility model provides a can take out the crystal safely, improve the yield of crystal, reduce artificial error, simple structure, the strong operability solves the automatic crystal anchor clamps that the crystal presss from both sides the fracture and the problem of gouging.

The purpose of the utility model is realized like this: the device comprises a motor rotating shaft, a support frame, an internal chain, a mechanical arm, a pressure sensor, a circular ring clamping rod and a connecting ring, wherein the support frame is a cross flower stand, a clamping groove slideway is arranged below the support frame, and the slideway is positioned in the lower end of the support frame and is arranged from the end part of the cross flower stand to the central position; the motor rotating shaft is positioned in the center of the support frame, the outer surface of the motor rotating shaft is provided with threads, the bottom of the motor rotating shaft is inserted into the support frame, the mechanical arm is positioned in a slideway of the support frame, and the part of the mechanical arm extending into the support frame is provided with threads; a motor rotating shaft in the support frame is connected with the mechanical arm through an internal chain, and the internal chain drives the connecting rod to move in the slideway along the thread of the motor rotating shaft; the pressure sensor is arranged at the bottom of the mechanical arm; the annular clamping rod is arranged on the inner side of the pressure sensor; the connecting ring is arranged at the top of the rotating shaft of the motor.

The utility model discloses there are some characteristics as follows:

1. the crystal clamp is suitable for crystals with various specifications;

2. the bending degree and the angle of the annular clamping rod used by the crystal clamp can be set according to the crystal specification.

3. The pressure sensor, the ring clamping rod and the motor rotating shaft are all electrically connected with a computer control device, and the computer control device controls the ring clamping rod to clamp the crystal and the motor rotating shaft to stop rotating when the clamping force of the pressure sensor is 1950-2050N.

The utility model discloses the clamp that produces when can effectively avoiding the crystal to take out splits. The beneficial effects of the utility model are that:

1. the utility model discloses but utilize pressure sensor accurate monitoring anchor clamps and the distance of crystal, reduce the tradition and draw the people of crystal mode and press from both sides the fracture for the crystal, improve crystal yield and follow-up processing out material.

2. The utility model discloses the design of square ring clamping bar prevents to make the crystal press from both sides and splits because of the crystal atress is inhomogeneous, can effectively guarantee the crystal quality of coming out of the furnace.
