Description

Technical Field

[0001] This utility model relates to the field of crystal extraction technology, specifically a sapphire crystal furnace extraction device. Background Technology

[0002] The chemical composition of synthetic sapphire ingots is aluminum oxide, which is composed of three oxygen atoms and two aluminum atoms bonded by covalent bonds. Its crystal structure is a hexagonal lattice structure. The production process of synthetic sapphire is as follows: raw material preparation → filling raw material and setting up crystal seed → vacuuming the furnace → heating the furnace (molybdenum heat shield and tungsten heat shield are added to the furnace) → raw material melting → fusing crystal seed → crystal neck growth → crystal growth → separation of crystal from crucible → cooling → crystal removal.

[0003] When a crystal is placed in the crucible of a sapphire crystal growth furnace, it cannot be removed by clamping. Existing technologies mostly use vacuum chucks to pick it up and remove it from the furnace. However, during the picking, lifting, and subsequent transfer processes, there is a risk that the vacuum suction may weaken and the crystal may fall out. Therefore, we propose a sapphire crystal removal device for a sapphire crystal furnace. Summary of the Invention

[0004] The purpose of this invention is to provide a sapphire crystal furnace crystal extraction device. By setting lifting plates on both sides of the base plate, which can be driven and raised by multi-stage electric push rods, and horizontally installing second electric push rods on the surface of the plates, and fixing clamping plates with rubber blocks at the ends, when the vacuum suction cup adsorbs and lifts the sapphire crystal ingot, the clamping plates can be driven to clamp the outer surface of the crystal ingot through the rubber blocks and rise together with the crystal ingot, ensuring stable locking of the crystal ingot and avoiding the risk of falling, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sapphire crystal furnace crystal extraction device, comprising a base plate and an upper plate, wherein the upper plate is fixed above the base plate by pillars at its four corners, the upper plate is parallel to the base plate, a first electric push rod is installed at the middle position of the surface of the upper plate, and a vacuum suction cup is installed and fixed at the end of the first electric push rod; both sides of the upper part of the base plate are provided with liftable lifting plates, a side plate is fixed to the outer side of the middle position of the lifting plate, a second electric push rod is horizontally installed on the surface of the lifting plate and the side plate, a clamping plate is fixed at the end of the second electric push rod, and a rubber block is fixed to the inner surface of the clamping plate; multiple electric push rods are vertically installed below the middle position of the lifting plate and between it and the base plate, and the pillars slide through both sides of the lifting plate.

[0006] By adopting the above technical solution, the vacuum chuck is first driven to extend into the crucible of the crystal growth furnace. Then, the vacuum chuck is used to lift the crystal ingot. After the crystal ingot is lifted from the crucible, the clamping plate is used to clamp it against the outer surface of the crystal ingot through the rubber block and lift it together with it, ensuring the stability of the crystal ingot during the adsorption, lifting and transfer process.

[0007] Optionally, the surface of the rubber block is provided with an arc-shaped groove, which matches the outer surface of the sapphire crystal ingot.

[0008] By adopting the above technical solution, the arc-shaped groove of the rubber block can better adhere to the outer surface of the sapphire ingot, thereby achieving a better anti-slip clamping effect.

[0009] Optionally, four rollers are installed at each of the four bottom corners of the base plate.

[0010] By adopting the above technical solution, the device can be moved by moving the base plate with rollers.

[0011] Optionally, the surface of the base plate has an opening, and the side of the opening is open to the outside.

[0012] By adopting the above technical solution, when the device is pushed, the sapphire crystal growth furnace extends through the opening directly below the vacuum chuck.

[0013] Optionally, the lifting plate surface at the support column is provided with rod holes, through which the support column can slide through the lifting plate.

[0014] Optionally, a handle is welded and fixed to the surface of the lifting plate, and the handle is located on the surface of the lifting plate on the side of the second electric push rod.

[0015] By adopting the above technical solution, a push can be applied to the lifting plate via the handle, which is then transmitted to the overall structure, causing it to move.

[0016] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0017] 1. The technical solution of this application is to set up lifting plates on both sides of the base plate, which can be driven to rise and fall by multi-stage electric push rods. The second electric push rod is horizontally installed on its surface, and a clamping plate with rubber blocks is fixed at the end. When the vacuum suction cup picks up and lifts the sapphire crystal ingot, it can drive the clamping plate to clamp the outer surface of the crystal ingot through the rubber blocks, so as to ensure the stable locking of the crystal ingot and avoid the risk of falling.

[0018] 2. The technical solution of this application installs multi-stage electric push rods at the bottom of the lifting plate, so that the second electric push rod can rise and fall synchronously with the crystal ingot. During the entire process of lifting and lowering the sapphire crystal ingot, it can be stabilized by the clamping effect from the clamping plate and rubber block. Attached Figure Description

[0023] Please see Figure 1-2 This utility model provides a technical solution: a sapphire crystal furnace crystal extraction device, including a base plate 1 and an upper plate 2. The upper plate 2 is placed horizontally directly above the base plate 1. The base plate 1 is vertically fixed above the four corners of the upper plate 2. The upper plate 2 is fixed above the base plate 1 by the four corner pillars 13 at its bottom. The pillars 13 are of the same length, so that the upper plate 2 is parallel to the base plate 1.

[0024] Rollers 12 are installed at the four corners of the bottom of the base plate 1. There are four rollers 12, which can drive the base plate 1 and the structure above it to move. An opening 11 is opened on the surface of the base plate 1. The side of the opening 11 is open to the outside. When moving, the sapphire crystal growth furnace can be placed in the opening 11, which is convenient for the subsequent lifting operation of the sapphire crystal ingot.

[0025] A first electric actuator 21 is installed in the middle of the surface of the upper plate 2. The protruding end of the first electric actuator 21 extends through to the bottom of the upper plate 2, and a vacuum chuck 211 is fixedly installed at the end of the first electric actuator 21. In use, the vacuum chuck 211 is connected to a negative pressure pump, and the first electric actuator 21 is connected to the control device and powered on. This can drive the vacuum chuck 211 to descend into the crucible of the sapphire crystal growth furnace. Activating the vacuum chuck 211 and raising the first electric actuator 21 can lift the sapphire ingot from the crucible and remove it.

[0026] Liftable lifting plates 3 are provided on both sides above the base plate 1. A multi-stage electric actuator 14 is vertically installed between the lower part of the middle position of the lifting plate 3 and the base plate 1. A rod hole 33 is opened on the surface of the lifting plate 3 at the support column 13. The support column 13 can slide through the two sides of the lifting plate 3 through the rod hole 33. When working, the multi-stage electric actuator 14 can drive the lifting plate 3 to rise or fall.

[0027] A side plate 31 is fixed to the outer side of the middle position of the lifting plate 3. A second electric push rod 4 is horizontally installed on the surface of the lifting plate 3 and the side plate 31. The extended end of the second electric push rod 4 faces inward. A clamping plate 41 is fixed to the end of the extended end of the second electric push rod 4. A rubber block 411 is fixed to the inner surface of the clamping plate 41. The surface of the rubber block 411 is provided with an arc-shaped groove. The arc-shaped groove matches the outer surface of the sapphire crystal ingot. When the crystal is lifted from the crystal growth furnace, the height of the lifting plate 3 can be adjusted immediately, and the second electric push rod 4 drives the clamping plate 41 to clamp and abut against the outer surface of the sapphire crystal ingot using the rubber block 411. This achieves stability of the crystal ingot and prevents it from falling. The multi-stage electric push rod 14 can drive the lifting plate 3 and the second electric push rod 4 to rise together with the crystal ingot, ensuring stability throughout the entire process of lifting and removing the crystal ingot.

[0028] In addition, a handle 32 is welded and fixed to the surface of the lifting plate 3. The handle 32 is located on the surface of the lifting plate 3 on the side of the second electric push rod 4. The device can be moved by pushing the handle 32. When the ingot moves within a small range, it can be moved by the roller 12 at the bottom of the device.

[0029] In use, by supporting the handle 32, the device can be pushed to roll on the ground under the rolling action of the roller 12, pushing the device to the sapphire crystal growth furnace. After the sapphire ingot cools down, the device is pushed so that the sapphire crystal growth furnace is placed directly below the vacuum suction cup 211 through the opening 11. The vacuum suction cup 211 is connected to the negative pressure pump. After locking the roller 12, the first electric push rod 21 drives the vacuum suction cup 211 to lower the height until the vacuum suction cup 211 touches the surface of the sapphire ingot. Then, the vacuum suction cup 211 is activated to use the vacuum negative pressure to adsorb the sapphire ingot, and the first electric push rod 21 drives the vacuum suction cup 211 to raise the sapphire ingot again. Before this, the multi-stage electric push rod 14 first drives the lifting plate 3 to raise and lower the height, so that the second electric push rod 4 and its end clamp 41 and other structures are exactly placed in the opening 11 of the sapphire crystal growth furnace. At a slightly higher position, after the vacuum suction cup 211 lifts the sapphire ingot to a height above the outlet of the sapphire crystal growth furnace, the second electric pusher immediately controls the clamping plates 41 and rubber blocks 411 on both sides to approach the sapphire ingot until the rubber blocks 411 on the surface of the clamping plates 41 press against the outer surface of the sapphire ingot, thereby clamping and locking it. Then, as the first electric pusher 21 continues to lift the vacuum suction cup 211 and the sapphire ingot, the multi-stage electric pusher 14 simultaneously lifts the lifting plate 3 and the second electric pusher 4, achieving a stabilizing effect on the sapphire ingot and avoiding the risk of the ingot falling during the lifting or transfer process. When it is necessary to remove the ingot, a receiving structure is set directly below the ingot so that the vacuum suction cup 211 no longer adheres to the ingot. At the same time, the second electric pusher 4 drives the clamping plates 41 to separate outward, thereby putting the sapphire ingot down.
