Description

Technical Field

[0001] This utility model relates to the field of crucible transfer technology, specifically to a quartz crucible positioning and transfer structure. Background Technology

[0002] Quartz crucibles are widely used due to their low cost and ease of processing and manufacturing. They possess high chemical stability, allowing them to withstand chemical corrosion and thermal shock at high temperatures. However, after production, quartz crucibles require a transfer device for transport.

[0003] A search revealed a quartz crucible positioning and transfer structure with patent number CN221563149U. This structure offers advantages such as precise positioning of the quartz crucible, effectively preventing damage. However, during the positioning process, the positioning plate presses against the inside of the crucible. If the crucible's position on the transfer plate deviates during this pressing process, the forces exerted on the crucible by the two positioning plates will differ. Alternatively, to achieve force balance between the two positioning plates, the crucible may be pushed to move on the transfer plate. This can lead to friction between the bottom of the crucible and the transfer plate, potentially causing damage. Therefore, a quartz crucible positioning and transfer structure is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a quartz crucible positioning and transfer structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quartz crucible positioning and transfer structure, including a transport vehicle plate, the upper surface of which is recessed inward, and a support ring is provided in the recess. The support ring is used to support the bottom of the quartz crucible, and a ball bearing is installed between the support ring and the recess. A support component is installed on the plate corresponding to the middle of the support ring to support the interior of the quartz crucible. The quartz crucible is positioned by the support component, and the support ring assists in adjusting the position of the quartz crucible during the positioning process.

[0006] Preferably, the support assembly includes a column, a first connecting rod hinged to the column, a second connecting rod hinged to the first connecting rod, a support block hinged to the end of the second connecting rod, a spring provided between the support block and the second connecting rod, and a drive assembly installed on the column for driving the support block to support the interior of the quartz crucible.

[0007] Preferably, the drive assembly includes a motor mounted on the top of the column, a lead screw mounted on the output end of the motor, the lead screw extending into an opening on the column and rotatably connected to the bottom end, a collar slidably mounted on the column, the collar being sealed at the opening and screwed to the lead screw, and a connecting component for supporting the hinge joint between the first connecting rod and the second connecting rod on the collar.

[0008] Preferably, the connecting component is a telescopic rod provided on the outer side wall of the collar, the extended end of the telescopic rod corresponds to the unfolding direction of the support block, and the end of the telescopic rod is hinged to the connecting shaft where the first connecting rod and the second connecting rod are hinged. When the collar is lifted, the included angle between the first connecting rod and the second connecting rod is adjusted, and the telescopic rod extends outward as the included angle increases.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: A quartz crucible positioning and transfer structure, by setting a support ring and ball bearings on a flat plate, places the quartz crucible on the support ring for support. When the support component supports the inside of the quartz crucible, the support ring slides in the recessed area under the action of the ball bearings as the support component pushes, thereby adjusting the position of the quartz crucible and making the force of the support component acting on the inside of the quartz crucible more balanced, thus positioning the quartz crucible. The support component can also limit the position of the support ring to prevent it from sliding during the transfer process. Attached Figure Description

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3 This utility model provides a technical solution: a quartz crucible positioning and transfer structure, including a transport vehicle plate 1, the upper surface of the plate 1 is recessed inward 2, and a support ring 3 is provided in the recess. The support ring 3 is used to support the bottom of the quartz crucible, and a ball bearing 4 is installed between the support ring 2 and the recess 3. A support component 5 is installed on the plate 1 corresponding to the middle of the support ring 2 to support the interior of the quartz crucible. The quartz crucible is positioned by the support component 5, and the support ring 2 assists in adjusting the position of the quartz crucible during the positioning process.

[0016] The recess 2 is an annular recess, and the support ring 3 is located in the annular recess. There is a gap between the support ring 3 and the recess 2, which allows the support ring 3 to move inside the recess with the assistance of the ball bearings 4.

[0017] The support assembly 5 includes a column 51, a first connecting rod 52 hinged to the column 51, a second connecting rod 53 hinged to the first connecting rod 52, a support block 54 hinged to the end of the second connecting rod 53, a spring 55 provided between the support block 54 and the second connecting rod 53, and a drive assembly 56 installed on the column 51 for driving the support block 54 to support the interior of the quartz crucible.

[0018] The drive assembly 56 includes a motor 561 mounted on the top of the column 51. A lead screw 562 is mounted on the output end of the motor 561. The lead screw 562 extends into an opening 563 on the column 51 and is rotatably connected to the bottom end. A collar 564 is slidably disposed on the column 51. The collar 564 is sealed at the opening 563 and is screwed to the lead screw 562. A connecting assembly 565 is provided on the collar 564 for supporting the hinge joint between the first connecting rod 52 and the second connecting rod 53.

[0019] The connecting component 565 is a telescopic rod fixedly connected to the outer wall of the collar 564. The extended end of the telescopic rod 565 corresponds to the unfolding direction of the support block 54. The end of the telescopic rod is hinged to the connecting shaft where the first connecting rod 52 and the second connecting rod 53 are hinged. When the collar 564 is lifted, the included angle between the first connecting rod 52 and the second connecting rod 53 is adjusted, and the telescopic rod extends outward as the included angle increases.

[0020] Working principle: First, adjust the position of the support ring 3 in the recess 2 so that the support ring 3 and the recess 2 are coaxial. Then, place the processed quartz crucible on the support ring 3. Then, start the motor 561. The motor 561 drives the lead screw 562 to rotate. The lead screw 562 drives the collar 564 to slide upward on the column 51. The first connecting rod 52 extends outward as the collar 564 is lifted, and drives the connecting component 565 to extend. The included angle between the first connecting rod 52 and the second connecting rod 53 increases, driving the support block 54 to move closer to the inner end of the quartz crucible until it is in contact with the inner wall of the quartz crucible. The angle of the support block 54 is adjusted by the spring 55 to increase the contact area between the support block 54 and the inner wall of the quartz crucible. During the positioning process of the quartz crucible, as the support block 54 is pushed, the quartz crucible adjusts its position with the assistance of the support ring 3 and the ball bearing 4 until the supporting force of the two support blocks 54 on the inner wall of the quartz crucible is the same. The position adjustment is completed and the crucible is fixed at the same time.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
