Description

Technical Field

[0001] The utility model relates to the technical field of crucibles, in particular to a crucible grabbing machine capable of stably grabbing. Background Art

[0002] Quartz crucibles are mainly used in the photovoltaic and semiconductor fields. They are used in the process of pulling single crystal silicon rods by the Czochralski method. They are consumable materials used to hold silicon materials in single crystal furnaces. Due to the high temperature environment, they need to be replaced every 200-400 hours of use. The growth of crystal rods is time-consuming and costly, so the success rate of growth is crucial. The quartz crucible is the only component that is in direct contact with the silicon material and has an important impact on the production results. When using a crucible for chemical reactions, it is often necessary to use crucible tongs to clamp the crucible for heating or to remove the crucible from the heat source.

[0003] When using the existing crucible clamping device, the operator often holds the crucible with a handheld crucible tongs, which requires a relatively large gripping force to keep the crucible stable. The operation of clamping the crucible is extremely laborious, and the crucible may fall off if not paid attention, which brings certain adverse effects to people's use process. In order to solve the shortcomings of the existing technology, we propose a crucible grabber that can stably grasp. Utility Model Content

[0012] Beneficial Effects

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. In the utility model, the crucible is clamped by the provided clamping block. When the crucible needs to be clamped, the device is moved to the vicinity of the crucible by the crawler wheel, so that the clamping block is located directly above the crucible, and the rotating motor is started. Under the action of the rotating motor, the threaded column begins to rotate, and the threaded sleeve moves up and down on the threaded column. At this time, the slider slides in the groove to cooperate with the movement of the threaded sleeve, which can ensure the stability of the movement direction of the threaded sleeve and avoid the position of the threaded sleeve from being offset. The threaded sleeve drives the moving column to move synchronously, thereby adjusting the distance between the moving column and the crucible, so that the clamping block contacts the crucible and clamps the crucible. Then, the rotating motor is used to make the moving column rise, and then the crawler wheel is used to move the device to the designated location, and the crucible is put down. In this way, the crucible is clamped mechanically, which saves manpower, and the crucible will not fall off, and the stability of the crucible can be maintained. Among them, a rubber pad is provided on the side where the clamping block contacts the crucible, and the rubber pad can increase the friction coefficient, so that the clamping of the crucible is more stable.

[0015] 2. In the utility model, the distance between the clamping blocks is adjusted by the electric push rod. When facing crucibles of different sizes, the distance between the two groups of clamping blocks also needs to be adjusted. The movable rod can be rotated in the first shaft seat by telescopic electric push rod, and the angle of the movable rod can be adjusted, so as to adjust the distance between the two groups of clamping blocks to adapt to crucibles of different sizes. At the same time, the electric push rod can also rotate in the second shaft seat. In this way, crucibles of more sizes can be clamped by one device, which increases the practicality of the device, uses mechanical automatic clamping, and saves manpower.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] Embodiment 1, as Figure 1-4 As shown, a crucible grabber that can grasp stably, when in use, the device is moved to the vicinity of the crucible to be grasped by the crawler wheel 2, so that the clamping block 18 is located directly above the crucible, and the rotating motor 8 is started. The output end of the rotating motor 8 is connected to the threaded column 9. Under the action of the rotating motor 8, the threaded column 9 starts to rotate, and the threaded sleeve 12 is rotationally connected to the threaded column 9 through a thread. When the threaded column 9 rotates, the threaded sleeve 12 moves up and down on the threaded column 9. At this time, the slider 11 slides in the groove 10 to maintain the stability of the direction of the threaded sleeve 12 when it slides, and the moving column 5 is driven downward by the threaded sleeve 12 until the clamping block 18 contacts the crucible to clamp the crucible.

[0023] Embodiment 2, as Figure 1-4As shown, a crucible grabber that can stably grab crucibles of different sizes is used. The electric push rod 21 is started. Under the pushing action of the electric push rod 21, the movable rod 17 can rotate in the first shaft seat 15 to complete the angle adjustment of the movable rod 17, thereby changing the distance between the two groups of clamping blocks 18 to adapt to crucibles of different sizes. In this way, the clamping block 18 clamps the crucible. A rubber pad 19 is also provided on the side of the clamping block 18 that contacts the crucible. The rubber pad 19 can make the clamping effect of the clamping block 18 better. After the crucible is clamped, the device is moved to the designated location by the crawler wheel 2, and the movable column 5 is moved up and down by rotating the motor 8 until the crucible falls at the designated location. Then the distance between the two groups of clamping blocks 18 is expanded by the electric push rod 21 to release the clamping limit of the crucible, so that the crucible can be stably grabbed to the designated location.

[0024] How it works

[0025] It should be noted that the utility model is a crucible grabber that can grasp stably. When in use, the device is moved to the vicinity of the crucible to be clamped by the crawler wheel 2, so that the clamping block 18 is located directly above the crucible, the rotating motor 8 is started, the threaded column 9 begins to rotate, the threaded sleeve 12 moves up and down on the threaded column 9, and the movable column 5 is driven by the threaded sleeve 12 to move downward until the clamping block 18 contacts the crucible to clamp the crucible. When facing crucibles of different sizes, the electric push rod 21 is started. Under the pushing action of the electric push rod 21, the movable rod 17 can rotate in the first shaft seat 15 to complete the angle adjustment of the movable rod 17, thereby changing the distance between the two groups of clamping blocks 18 to adapt to crucibles of different sizes. In this way, the clamping block 18 clamps the crucible. A rubber pad 19 is also provided on the side where the clamping block 18 contacts the crucible. The rubber pad 19 can make the clamping effect of the clamping block 18 better, so that the crucible can be grasped stably.
