Description

Technical Field

[0001] This application relates to the field of silicon carbide growth technology, and more specifically, to a crucible lifting and fixing device and a crucible transfer device. Background Technology

[0002] In the process of silicon carbide crystal growth, an outer crucible is usually needed to contain the crystal growth environment. When the outer crucible is being loaded into and unloaded from the furnace, a lifting device needs to be manually attached to it to facilitate transfer.

[0003] The inventor's research revealed that the old-fashioned lifting device usually consists of two buckles and a lifting strap. The buckles need to be manually aligned with the locking holes on the outer crucible before the bolts are tightened. The tightening and loosening process often results in the threads getting stuck, which is time-consuming and laborious. Utility Model Content

[0004] The purpose of this application is to provide a crucible lifting and fixing device that can automatically hold the external crucible hole, avoiding the problem of jamming caused by the tightening and loosening of conventional buckles, thus saving time and effort.

[0005] To achieve the above objectives, this utility model is implemented through the following solution.

[0006] In a first aspect, this utility model provides a crucible lifting and fixing device, comprising:

[0007] Lifting bracket;

[0008] A drive assembly is disposed on the lifting bracket;

[0009] A sliding rod is mounted on the lifting bracket and located on the bottom side of the drive assembly;

[0010] Two positioning supports are slidably mounted on the slide rod and are connected to the drive assembly in a transmission manner.

[0011] The two positioning supports are configured to move away from or towards each other under the drive of the drive assembly, so as to be positioned and held on the inner wall of the outer crucible or detached from the outer crucible.

[0012] In an optional embodiment, the drive assembly includes a drive member, a transmission member, and a transmission screw. The two positioning supports are disposed opposite to each other on the slide rod. The drive member is disposed on the lifting bracket. The two ends of the transmission screw are threadedly connected to the two positioning supports respectively. The transmission member is simultaneously connected to the drive member and the transmission screw. The drive member is configured to drive the transmission screw to rotate through the transmission member, thereby causing the two positioning supports to move closer to or further away from each other.

[0013] In an optional embodiment, the driving component includes a drive motor, and the transmission component includes a first transmission gear and a second transmission gear. The first transmission gear is disposed on the output shaft of the drive motor, and the second transmission gear is fixedly disposed in the middle of the transmission lead screw. The first transmission gear and the second transmission gear mesh with each other.

[0014] In an optional embodiment, the transmission screw includes a transmission section and threaded sections disposed at both ends of the transmission section, and the top ends of the two positioning supports are provided with threaded holes, and the two threaded sections are respectively assembled into the two threaded holes.

[0015] In an optional embodiment, the diameter of the threaded section is smaller than the diameter of the transmission section.

[0016] In an optional embodiment, there are two slide rods, both of which are parallel to the transmission lead screw, and both ends of each slide rod are connected to the lifting bracket.

[0017] In an optional embodiment, the lifting bracket includes a horizontal frame, a handle, and two vertical frames. The driving assembly is disposed in the middle of the horizontal frame, and the two vertical frames are respectively disposed at both ends of the horizontal frame and correspond to the two positioning supports. The handle is disposed on the horizontal frame.

[0018] In an optional embodiment, each of the two positioning supports is provided with a positioning pillar on its opposite side. The positioning pillar is provided corresponding to the vertical frame and is configured to fit into the positioning hole on the outer crucible.

[0019] In an optional embodiment, both of the vertical frames are provided with bearing holes, which correspond to the positioning support and are configured to accommodate the end of the positioning support.

[0020] In an optional embodiment, the handle is provided with movable connectors at both ends, which are movably connected to the two ends of the crossbar.

[0021] On the other hand, this utility model embodiment provides a crucible transfer device, including a lifting drive device and the aforementioned crucible lifting and fixing device. The lifting drive device is disposed above the lifting bracket and configured to lift the lifting bracket.

[0022] Through the above technical solution, this application additionally designs a driving component, which is set on the lifting bracket. The lifting bracket is also equipped with a sliding rod, and two positioning support members are slidably set on the sliding rod and are connected to the driving component. The two positioning support members can move away from each other or move closer together under the drive of the driving component. In actual use, the driving component can first be used to drive the two positioning support members to move closer together, so that the distance between the two positioning support members is less than the inner diameter of the outer crucible. Then, the two positioning support members are installed into the outer crucible and aligned with the locking holes on the outer crucible. Then, the driving component is used to drive the two positioning support members to move away from each other and lock them into the locking holes on the inner wall of the outer crucible, thus achieving locking and positioning. Finally, the external device is used to lift the crucible. Compared with the prior art, the crucible lifting and fixing device provided by this utility model can automatically lock the holes of the outer crucible, avoiding the problem of jamming caused by the tightening and loosening of conventional buckles, saving time and effort.

[0033] Please see Figure 1 and Figure 2 This utility model provides a crucible lifting and fixing device 100, which can automatically hold the external crucible hole, avoiding the problem of jamming caused by the tightening and loosening of conventional buckles, saving time and effort.

[0034] The crucible lifting and fixing device 100 provided in this embodiment of the utility model includes a lifting bracket 110, a driving assembly 130, a sliding rod 150, and two positioning support members 170. The lifting bracket 110 serves as an integral support frame, and the driving assembly 130 is disposed on the lifting bracket 110. The sliding rod 150 is disposed on the lifting bracket 110 and located on the bottom side of the driving assembly 130. The two positioning support members 170 are slidably disposed on the sliding rod 150 and are connected to the driving assembly 130 in a transmission manner. The two positioning support members 170 are configured to move away from or towards each other under the drive of the driving assembly 130, so as to position and hold them on the inner wall of the outer crucible or detach them from the outer crucible.

[0035] In practical use, the driving component 130 can be used to drive the two positioning support members 170 to move closer to each other, so that the distance between the two positioning support members 170 is less than the inner diameter of the outer crucible. Then, the two positioning support members 170 are installed into the outer crucible and aligned with the locking holes on the outer crucible. Then, the driving component 130 is used to drive the two positioning support members 170 to move away from each other and position them in the locking holes on the inner wall of the outer crucible to achieve locking and positioning. Finally, the lifting is achieved using external equipment.

[0036] In this embodiment, the lifting bracket 110 is also provided with a button for controlling the action of the drive component 130. The drive component 130 can be started by the button and the driving direction of the drive component 130 can be controlled, so as to make the two positioning supports 170 move closer to each other or further apart.

[0037] Furthermore, the drive assembly 130 includes a drive member 131, a transmission member 133, and a transmission screw 135. Two positioning supports 170 are disposed opposite to each other on the slide rod 150. The drive member 131 is disposed on the lifting bracket 110. The two ends of the transmission screw 135 are respectively threaded to the two positioning supports 170. The transmission member 133 is simultaneously connected to both the drive member 131 and the transmission screw 135. The drive member 131 is configured to drive the transmission screw 135 to rotate through the transmission member 133, so as to drive the two positioning supports 170 to move closer to or further away from each other. Specifically, the transmission screw 135 and the slide bar 150 are parallel to each other, and the transmission screw 135 is threadedly engaged with the top ends of the two positioning support members 170. The rotation of the transmission screw 135 can drive the two positioning support members 170 to move closer to each other or further apart. For example, when the transmission screw 135 rotates forward, the two positioning support members 170 move closer to each other, and when the transmission screw 135 rotates in reverse, the two positioning support members 170 move further apart.

[0038] See Figure 3The driving component 131 includes a drive motor, and the transmission component 133 includes a first transmission gear 137 and a second transmission gear 139. The first transmission gear 137 is mounted on the output shaft of the drive motor, and the second transmission gear 139 is fixedly mounted in the middle of the transmission screw 135. The first transmission gear 137 and the second transmission gear 139 mesh with each other. Specifically, the first transmission gear 137 and the second transmission gear 139 have different sizes; for example, the diameter of the first transmission gear 137 is smaller than the diameter of the second transmission gear 139. This allows the transmission component 133 to achieve a speed reduction effect, making the rotation speed of the transmission screw 135 more controllable. The speed at which the first positioning support 170 and the second positioning support 170 approach or move away from each other is also more controllable, ensuring the stability and reliability of the driving process.

[0039] In this embodiment, the transmission screw 135 includes a transmission section 1351 and threaded sections 1353 disposed at both ends of the transmission section 1351. Each of the two positioning support members 170 has a threaded hole 171 at its top, and the two threaded sections 1353 are respectively fitted into the two threaded holes 171. Specifically, the second transmission gear 139 is fixedly disposed in the middle of the transmission section 1351, thereby driving the transmission section 1351 and the threaded sections 1353 to rotate. The two threaded sections 1353 have different rotation directions, thus enabling the two positioning support members 170 to move in opposite directions during the rotation of the transmission screw 135. The transmission section 1351 may not have external threads, thereby preventing the positioning support members 170 from moving into the transmission section 1351.

[0040] Furthermore, the diameter of the threaded section 1353 is smaller than the diameter of the transmission section 1351. Specifically, the joint between the transmission section 1351 and the threaded section 1353 can form a stepped structure, thereby stopping the positioning support 170. Since the length of the threaded section 1353 is sufficient for the positioning support 170 to disengage from the positioning hole on the inner wall of the outer crucible, the smaller diameter of the threaded section 1353 prevents the positioning support 170 from moving further into the transmission section 1351, avoiding edge jamming that could affect the driving process.

[0041] Please continue reading Figure 1 and Figure 2 In this embodiment, there are two slide rods 150, both parallel to the transmission screw 135, and both ends of each slide rod 150 are connected to the lifting bracket 110. Specifically, the slide rods 150 serve as driving guides, and the two slide rods 150 can be arranged at intervals in the vertical direction. The positioning support 170 is provided with two corresponding sliding holes, the size of which is slightly larger than the size of the slide rod 150, and the two are fitted together. The design of the two slide rods 150 can better achieve guidance and avoid large lateral swing during the rotation of the transmission screw 135, which would affect the movement of the positioning support 170.

[0042] In this embodiment, the lifting support 110 includes a horizontal frame 111, a handle 113, and two vertical frames 115. A drive assembly 130 is located in the middle of the horizontal frame 111, and the two vertical frames 115 are respectively located at both ends of the horizontal frame 111 and correspond to two positioning supports 170. The handle 113 is mounted on the horizontal frame 111. Specifically, the horizontal frame 111 is parallel to the slide rod 150 and the transmission screw 135. The drive motor can be fixedly mounted in the middle of the horizontal frame 111. The two vertical frames 115 are integrally mounted at both ends of the horizontal frame 111 and extend downwards. The two positioning supports 170 are correspondingly positioned to the two vertical frames 115, forming a groove between the positioning supports 170 and the corresponding vertical frame 115 to accommodate the sidewall of the outer crucible. The handle 113 is located at the top of the horizontal frame 111 and can be connected to the lifting drive device via an external sling to achieve the lifting action.

[0043] Furthermore, each of the two positioning supports 170 has a positioning pillar 173 on its opposite side. The positioning pillar 173 is correspondingly arranged with the vertical frame 115 and configured to fit into the positioning holes on the outer crucible. Specifically, the positioning support 170 extends downward, the positioning pillar 173 extends horizontally, and the two positioning pillars 173 can extend toward the two vertical frames 115 respectively, so that they can be correspondingly fitted into the two positioning holes on the outer crucible.

[0044] See Figure 4 In this embodiment, both vertical supports 115 are provided with bearing holes 117, which correspond to the positioning support column 173 and are configured to accommodate the end of the positioning support column 173. Specifically, the bearing holes 117 allow the end of the positioning support column 173 to be accommodated, ensuring that both ends of the positioning support column 173 are supported during the lifting action, thereby improving support stability and increasing the load-bearing capacity of the positioning support column 173.

[0045] Please continue reading Figure 1 In this embodiment, the handle 113 is provided with movable connectors 119 at both ends, which are movably connected to the two ends of the crossbar 111. Specifically, the movable connectors 119 can be connecting iron rings. By providing the movable connectors 119, the degree of freedom of the handle 113 can be guaranteed while ensuring the force transmission effect, making it easier to fix the external sling to the handle 113.

[0046] This utility model embodiment also provides a crucible transfer device, including a lifting drive device and the aforementioned crucible lifting and fixing device 100. The crucible lifting and fixing device 100 includes a lifting bracket 110, a drive assembly 130, a slide rod 150, and two positioning support members 170. The lifting bracket 110 serves as an integral support frame, and the drive assembly 130 is mounted on the lifting bracket 110. The slide rod 150 is mounted on the lifting bracket 110 and located on the bottom side of the drive assembly 130. The two positioning support members 170 are slidably mounted on the slide rod 150 and are connected to the drive assembly 130. The two positioning support members 170 are configured to move away from or towards each other under the drive of the drive assembly 130, so as to position and hold them against the inner wall of the outer crucible or detach them from the outer crucible. The lifting drive device is located above the lifting bracket 110 and is configured to lift the lifting bracket 110.

[0047] Specifically, the lifting drive device includes a lifting cylinder, a lifting arm, and a sling. The sling is mounted on the lifting arm and connected to the handle 113 of the lifting bracket 110. The lifting arm moves up and down via the lifting cylinder, which in turn lifts the lifting bracket 110 via the sling, thus completing the lifting and transfer of the outer crucible. For details on the specific structure and transfer principle of the lifting drive device, please refer to existing crucible transfer equipment.

[0048] Through the above technical solution, this utility model embodiment features an additional drive component 130, which is mounted on the lifting bracket 110. The lifting bracket 110 also has a slide rod 150, and two positioning supports 170 are slidably mounted on the slide rod 150 and are connected to the drive component 130. The two positioning supports 170 can move away from or towards each other under the drive of the drive component 130. In actual use, the drive component 130 can first be used to move the two positioning supports 170 closer together, making the distance between them less than the inner diameter of the outer crucible. Then, the two positioning supports 170 are inserted into the outer crucible and aligned with the locking holes on it. Next, the drive component 130 is used to move the two positioning supports 170 away from each other and position them in the locking holes on the inner wall of the outer crucible, achieving locking and positioning. Finally, an external device is used to lift the crucible. Compared with the prior art, the crucible lifting and fixing device 100 provided by this utility model can automatically lock the external crucible hole, avoiding the problem of jamming caused by the tightening and loosening of conventional buckles, saving time and effort.
