Abstract
The utility model discloses a monitoring device for crystal growth, which can automatically monitor mass change of a crystal. The monitoring device for the crystal growth comprises a support, a lift shaft arranged inside the support and a weighing sensor arranged at an inner top of the support. A base is fixedly arranged at a lower end of the weighing sensor, a driven hoist device is rotatably arranged inside the base, an upper end of the driven hoist device is located inside the base and a lower end of the driven hoist device extends outwards of the base, an upper end of the lift shaft is fixed inside the lower end of the driven hoist device, a driving sleeve is sleeved on the lift shaft, an upper end of the driving sleeve is located on a lateral side of the lower end of the driven hoist device and is fixedly connected with the lower end of the driven hoist device, and the lower end of the driving sleeve penetrates through the support and is connected with a driving device which is located outside the support and drives the driving sleeve to rotate. The monitoring device for the crystal growth has the advantages that the monitoring device for the crystal growth can automatically monitor the mass change of the crystal in growth, and monitoring effect is not influenced when the crystal rotates or moves upwards and downwards.
Description
Technical field
The utility model relates to a kind of crystal growth monitoring device.
Background technology
The application of crystal in our daily life more and more widely, and most of crystal all is a synthetic.Existing crystalline making method mostly adopts crystal pulling method; In order to ensure the crystalline quality; Need the various conditions of control crystal in process of growth, and the prerequisite of regulation and control crystal growth condition is exactly to judge whether to need to change crystal growth condition through the variation of weight in process of growth of inspection crystal.Original method all is to judge the crystalline growing state through manual observation crystalline vary in diameter; Because the crystal in the crystal pulling method needs rotation and moves up and down simultaneously; This just requires very high to testing staff's eyesight; But crystal move up and down and the situation of rotating under, the testing staff still is difficult to judge the crystalline vary in diameter, it is dizzy to be easy to be that the testing staff is taken place.The crystal of producing so just is difficult to guarantee its quality.
The utility model content
The utility model technical problem to be solved is: the crystal growth monitoring device that provides a kind of automatic monitoring crystal mass to change.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of crystal growth monitoring device, comprise that support and the interior top of lift shaft, support that is arranged in the support are provided with LOAD CELLS, and the lower end of said LOAD CELLS is set with pedestal; Rotate in the pedestal and be provided with driven hanging apparatus; The upper end of driven hanging apparatus is positioned at pedestal, and pedestal is stretched out in its lower end, and the upper end of lift shaft is fixed in the driven hanging apparatus lower end; Be arranged with drive sleeve on the lift shaft; The upper end of drive sleeve is positioned at driven hanging apparatus lower outside and is fixedly connected with the lower end of driven hanging apparatus, and the lower end of drive sleeve passes from support and links to each other in the drive unit that is positioned at the outside driving drive sleeve rotation of support, and the lower end of lift shaft also passes from support.
Said driven hanging apparatus comprises that rotating the weak point that the minor axis in the pedestal is set and links to each other with minor axis overlaps, and short cover is positioned at the pedestal downside.
The beneficial effect of the utility model is: the quality change when the crystal production gear of said structure can be monitored crystal growth automatically, and crystalline rotation and do not move up and down and can influence its monitoring effect.
Description of drawings
Fig. 1 is the structural representation of the utility model crystal growth monitoring device.
Among the figure: 1, support, 2, lift shaft, 3, LOAD CELLS, 4, pedestal, 5, minor axis, 6, short cover, 7, drive sleeve.
Embodiment
Below in conjunction with accompanying drawing, describe the specific embodiments of the utility model in detail.
As shown in Figure 1; The described crystal growth monitoring device of the utility model; Comprise that support 1 and the lift shaft 2, the support 1 interior top that are arranged in the support 1 are provided with LOAD CELLS 3, the lower end of said LOAD CELLS 3 is set with pedestal 4, rotates in the pedestal 4 and is provided with driven hanging apparatus.Driven hanging apparatus comprises that rotating the weak point that the minor axis 5 in the pedestal 4 is set and links to each other with minor axis through bearing overlaps 6, and short cover 6 is positioned at pedestal 4 downsides.When actual production, minor axis 5 also can be one-body molded with weak point cover 6.The upper end of lift shaft 2 is fixedly installed in the short cover 6.Be arranged with drive sleeve 7 on the lift shaft 2, the upper end of drive sleeve 7 is positioned at short cover 6 outsides and is fixedly connected with short cover 6.The drive unit (because of prior art, not drawing among the figure) that the lower end of drive sleeve 7 passes from support 1 and rotates in the driving drive sleeve that is positioned at support 1 outside 7 links to each other, and the lower end of lift shaft 2 also passes from support 1.
The working process of the utility model is: because in crystal pulling method and rotational method; Crystal needs rotation and moves up and down in the crystalline process; So utilizing drive unit to drive drive sleeve 7 rotates; The upper end of drive sleeve 7 drives short cover 6 and rotates, and short cover 6 drives minor axis 5 again and in pedestal 4, rotates, and LOAD CELLS 3 is not influenced by the rotation of minor axis 5 when measuring crystal weight.Simultaneously, short cover 6 also drives lift shaft 2 and rotates, and along with the rotation of lift shaft 2, the crystal that hangs over lift shaft 2 lower ends also begins to rotate.Crystalline moves up and down then and realizes through moving up and down crystal growth monitoring device and drive unit.In the above-mentioned working process, LOAD CELLS 3 is unaffected, can well monitor the crystalline weight change, thereby to crystallization condition a good reference is provided.
Claims (2)
1. crystal growth monitoring device; Comprise that support and the interior top of lift shaft, support that is arranged in the support are provided with LOAD CELLS; It is characterized in that: the lower end of said LOAD CELLS is set with pedestal, rotates in the pedestal and is provided with driven hanging apparatus, and the upper end of driven hanging apparatus is positioned at pedestal; Pedestal is stretched out in its lower end; The upper end of lift shaft is fixed in the driven hanging apparatus lower end, is arranged with drive sleeve on the lift shaft, and the upper end of drive sleeve is positioned at driven hanging apparatus lower outside and is fixedly connected with the lower end of driven hanging apparatus; The lower end of drive sleeve passes from support and links to each other in the drive unit that is positioned at the outside driving drive sleeve rotation of support, and the lower end of lift shaft also passes from support.
