[0032] The present application solves the technical problem of low efficiency of the clamping device in the prior art by providing a sapphire furnace clamping device, a clamping system and a sapphire furnace, thereby achieving the technical effects of improving the efficiency of the clamping device, improving the degree of automation of operation and reducing operational risks.

[0033] During the use of the sapphire furnace, the furnace cover 120 needs to be locked to achieve the sealing between the furnace cover 120 and the furnace chamber. Most of the existing sapphire furnace cover 120 clamping devices use a lock to press the edge of the furnace cover 120, and then use a threaded screw to lock it. The existing clamping device is complicated to operate and consumes a lot of man-hours. At the same time, the use of this structure requires a manual locking method. When locking, personnel need to operate close to the furnace chamber, which may cause the operator to be scalded by high temperature. Due to the complexity of its operation, the existing furnace cover 120 locking device cannot be locked synchronously, and it cannot ensure that all parts of the furnace cover 120 are locked at the same time, resulting in uneven force on each part, inconsistent pressure on the sealing ring, and irregular deformation of the sealing ring may occur due to inconsistent pressure, resulting in air leakage, reducing the life of the sealing ring. At the same time, since the sapphire furnace has certain requirements for cleanliness, the clamping device needs to avoid pollution as much as possible, and in order to reduce costs, the clamping device needs to be able to ensure the sealing of the furnace chamber after long-term use.

[0034] In order to solve the above technical problems, the present application provides a sapphire furnace clamping device, which adopts the following technical solution, please refer to Figure 1-3 , including: a base 200, a clamping member 300 and an operating block 400, the base 200 is arranged outside the furnace body 110, including a limiter 210, the limiter 210 includes a limiter surface 210A; the clamping member 300 includes a fixed end 310 and a movable end 320, the fixed end 310 is fixedly connected to the furnace cover 120, and the movable end 320 can be close to the base 200 and abut against the limiter surface 210A; the operating block 400 has a degree of freedom of movement, can move along a first direction to connect with the movable end 320, and drive the movable end 320 to move on the limiter surface 210A in a direction away from the furnace cover 120. The clamping of the sapphire furnace is completed.

[0035] Specifically, the sapphire furnace is Figure 1 As shown, the furnace body 110 includes a hollow furnace body 110 and a furnace cover 120 disposed at the top of the furnace body 110. A sealing ring is disposed between the furnace body 110 and the furnace cover 120. When the furnace cover 120 is placed at a designated position on the furnace body 110, a clamping device is required to clamp the furnace cover 120. The clamping device includes a base 200 installed outside the furnace body 110. The base 200 is fixedly connected to the furnace body 110 by welding or screwing, or is disposed on other components outside the furnace body 110. A stopper 210 is disposed on the base 200. The stopper 210 is fixedly connected to the base 200 by screwing, clamping, welding, etc. The stopper 210 includes a stopper surface 210A. The stopper surface 210A is preferably disposed perpendicular to the plane where the furnace cover 120 is located. In some cases, the stopper surface 210A may also have a certain angle with the plane where the furnace cover 120 is located, but the stopper surface 210A cannot be disposed parallel to the plane where the furnace cover 120 is located. Please refer to Figure 2-3 , and further comprises a clamping member 300, one end of which is fixedly connected to the furnace cover 120, and the connection method is preferably welding. The clamping member 300 comprises a movable end 320 away from the furnace cover 120, and at least part of the surface of the movable end 320 can abut against the aforementioned limiting surface 210A, and can slide on the limiting surface 210A. Since one end of the clamping member 300 is fixedly connected to the furnace cover 120, when the clamping member 300 is pulled, a pressure close to the furnace body 110 will be applied to the furnace cover 120, so as to complete the clamping of the furnace cover 120. The operating block 400 in the present application has a degree of freedom of movement, which is connected to the output end of a driving member, and can be moved along a first direction to connect with the aforementioned movable end 320 under the drive of the driving member, and push the clamping member 300 to move on the limiting surface 210A in a direction away from the furnace cover 120, so as to complete the clamping of the furnace cover 120.

[0036] In one embodiment, the angle between the first direction and the limiting surface 210A is α, 0°≤α≤90°, so that when the operating block 400 moves along the first direction, the limiting member 210 can cooperate with the movable end 320 to move along the limiting surface 210A in a direction away from the furnace cover 120. In this embodiment, the operating block 400 pushes the movable end 320 to complete the clamping by pressing. In another embodiment, the angle between the first direction and the limiting surface 210A is α, 90°≤α≤180°. In this embodiment, the operating block 400 drives the movable end 320 to complete the clamping by pulling.

[0037] By setting the operating block 400 to apply pressure to the movable end 320 of the clamping member 300, the movable end 320 of the clamping member 300 can move along the limiting surface 210A of the limiting member 210 to complete the clamping of the furnace cover 120. The movement of the clamping member 300 can be controlled by an external drive, thereby achieving the effect of simplifying the operation process of the clamping device, saving operating hours, and eliminating the need for manual close operation.

[0038] For further information, please refer to Figure 2-3 , the movable end 320 includes at least one inclined surface or curved surface, and the operating block 400 is provided with an inclined surface or curved surface corresponding thereto, and the operating block 400 can move along the first direction to abut against the inclined surface or curved surface on the movable end 320. Specifically, in the present application, the movable end 320 includes an inclined surface or curved surface, and the operating block 400 is provided with an inclined surface or curved surface corresponding thereto; wherein, when at least one of the operating block 400 or the movable end 320 is a curved surface, the operating block 400 and the clamping member 300 are point-connected, and when both the operating block 400 or the movable end 320 are inclined surfaces, the operating block 400 and the clamping member 300 are surface-connected; by arranging the operating block 400 and the clamping member 300 to be connected by means of surface connection or point connection, the operating block 400 can apply a force to the movable end 320 in a direction away from the furnace cover 120 along the limiting surface 210A by means of surface connection or point connection, thereby completing the clamping of the furnace cover 120.

[0039] For further information, please refer to Figure 2, the movable end 320 includes a first inclined surface 320A, and the operating block 400 includes a second inclined surface 400A. The first inclined surface 320A and the second inclined surface 400A are arranged in parallel, and the operating block 400 can move in a direction perpendicular to the limiting surface 210A until it abuts against the first inclined surface 320A. In one embodiment, the movable end 320 and the operating block 400 are arranged opposite to each other, and the movable end 320 is a rectangular block. The block-shaped movable end 320 includes a first inclined surface 320A. The first inclined surface 320A is arranged on a side close to the operating block 400, preferably at the top position of the side of the block-shaped movable end 320 close to the operating block 400, and the first inclined surface 320A connects the top and side of the movable end 320; in this embodiment, the operating block 400 is also block-shaped, wherein the operating block 400 includes a second inclined surface 400A, and the second inclined surface 400A is arranged on a side close to the movable end 320, preferably at the lower part of the side of the operating block 400 close to the movable end 320; wherein , the second inclined surface 400A is arranged parallel to the upper side of the first inclined surface 320A. Under the drive of the driving member, the second inclined surface 400A can approach the first inclined surface 320A in a direction perpendicular to the limiting member 210 until it contacts the first inclined surface 320A. The first inclined surface 320A and the second inclined surface 400A are connected by a surface. Then, the operating block 400 continues to move under the drive of the driving member; since one side of the movable end 320 contacts the limiting surface 210A, when the first inclined surface 320A pushes the second inclined surface 400A, the operating block 400 will apply a driving force to the movable end 320 to move it away from the furnace cover 120, thereby completing the locking of the furnace cover 120. During the operation, the locking force on the furnace chamber can be adjusted by changing the structural dimensions of the operating block 400 and the size and angle of the inclined surface according to the equipment requirements, thereby achieving the effect of simplifying the locking force operation method of the clamping device.

[0040] Please refer to Figure 3 , the movable end 320 includes a first curved surface 320B, and the operating block 400 includes a second curved surface 400B, the second curved surface 400B is arranged above the first curved surface 320B, and the second curved surface 400B can move along a direction perpendicular to the limiting surface 210A to connect with the first curved surface 320B.

[0041] Please refer to Figure 5The clamping member 300 includes: a clamping portion 330 and a first mounting groove 340, the clamping portion 330 is clamped with the furnace cover 120, and the clamping portion 330 is at least partially connected to the top of the furnace cover 120; the first mounting groove 340 is connected to the clamping portion 330 and is spaced apart from the furnace body 110.

[0042] Specifically, in one embodiment, the clamping member 300 includes a clamping portion 330, and the clamping portion 330 includes a clamping groove, which can cooperate with the contour of the furnace cover 120 and be clamped on the furnace cover 120. The clamping portion 330 is at least partially located at the top of the furnace cover 120. When the clamping member 300 is subjected to pressure away from the furnace cover 120, the clamping portion 330 can apply pressure to the furnace cover 120 to ensure the clamping of the furnace cover 120; the clamping portion 330 and the furnace cover 120 have further connection methods, including one of screw connection, welding, etc., to further improve the fastening force, and at the same time, the furnace cover 120 and the clamping member 300 can be raised and lowered synchronously, and there is no need to repeatedly install the clamping member 300, which simplifies the operation steps and saves operation time.

The first mounting groove 340 is provided on the side of the strip-shaped docking portion 220 close to the furnace body 110, and is spaced apart from the furnace body 110. By providing the first mounting groove 340, a gap can be formed between the strip-shaped connected portion of the clamping member 300 and the furnace body 110. When the clamping member 300 and the furnace cover 120 are installed on the furnace body 110 together, the clamping member 300 can be effectively prevented from scratching the furnace body 110, and at the same time, space can be left for the furnace body 110 to deform to avoid damage to the furnace body 110. It is obvious that the portion of the clamping member 300 that contacts the furnace cover 120 and the furnace body 110 can be made of a material different from that of the main body of the clamping member 300 to avoid damage to the furnace body 110 .
