Description

Technical Field

[0001] The utility model belongs to the fields of photovoltaics and semiconductors, and particularly relates to a flying material collection mechanism for quartz sand processing. Background Art

[0002] A quartz crucible is a sub - product of quartz glass products, which is made of high - purity quartz sand through mold shaping and arc - method high - temperature production. It has the characteristics of high temperature resistance, long service time, and high purity. The quartz crucible is mainly used as an auxiliary consumable for pulling high - purity single - crystal silicon rods in semiconductors and is a key one - time consumable for containing molten silicon liquid during the pulling process of single - crystal silicon rods. According to the downstream application scenarios of single - crystal silicon rods, quartz crucibles can be divided into quartz crucibles for semiconductor single - crystal growth (semiconductor quartz crucibles and quartz crucibles for photovoltaic single - crystal growth). In recent years, with the booming development of the photovoltaic and semiconductor industries, the demand for the output of quartz crucibles has been increasing year by year, and at the same time, higher requirements have been put forward for the quality of quartz crucibles and their production processes.

[0003] Quartz crucibles need to add different - quality quartz sand layer by layer in a stacked manner in a high - temperature environment. There are also differences in the quality of the added quartz sand, and the adding position and stacking method will also change according to the inner wall and bottom shape of the quartz crucible. Due to such complex process requirements, the existing production methods of quartz crucibles on the market are generally manual production methods.

[0004] Workers carry out continuous and highly concentrated labor in a high - temperature environment to prevent problems such as processing errors and environmental impurities. If impurities fall in during the processing or the thickness is uneven during the stacking process, the entire quartz crucible becomes a waste product. Currently, the market price of quartz sand is expensive, and the scrap rate increases, thereby increasing the cost of the entire quartz crucible and not meeting the positioning requirements of the market for quartz crucibles.

[0005] During the processing and production of quartz crucibles, high requirements are placed on cleanliness and the maximum utilization rate of materials. Therefore, saving material costs is also a theme that needs to be explored in the automated production of quartz crucibles. Summary of the Utility Model

[0011] The tail opening of the quartz sand collection discharge part discharges the material entering the quartz sand collection discharge part through the tail opening.

[0012] Furthermore, the opening height of the quartz sand collection feed part is greater than the openings of the front end of the quartz sand collector and the quartz sand collection discharge part.

[0013] Furthermore, the quartz sand collection discharge part is a horn-shaped shell.

[0014] Furthermore, the quartz sand collection bin is installed at a preset position through the collection bin support frame, and the quartz sand collection bin rotates relative to the collection bin support frame, with one extreme position being perpendicular to the horizontal plane and the other extreme position being parallel to the horizontal plane.

[0015] Furthermore, it also includes a collection bin turning shaft. The quartz sand collection bin is connected to the collection bin turning shaft, and the collection bin turning shaft rotates relative to the collection bin support frame through the power provided by the collection bin turning servo motor.

[0016] Furthermore, a collection bin horizontal in-place sensor and a collection bin horizontal buffer limit member are installed on the collection bin support frame. The collection bin horizontal in-place sensor detects the horizontal extreme position of the collection bin, and the collection bin horizontal buffer limit member is installed at a horizontal extreme movement position of the quartz sand collection bin to provide elastic buffer force and position support for the quartz sand collection bin.

[0017] Furthermore, a collection bin vertical in-place sensor and a collection bin vertical buffer limit member are installed on the collection bin support frame. The collection bin vertical in-place sensor detects the vertical extreme position of the collection bin, and the collection bin vertical buffer limit member is installed at a vertical extreme movement position of the quartz sand collection bin to provide elastic buffer force and position support for the quartz sand collection bin.

[0018] Furthermore, the quartz sand collection bin can be adjusted in position in three directions of X, Y, and Z relative to the quartz crucible melting furnace mold.

[0019] Furthermore, a collection bin Z-axis adjustment screw is connected to the bottom of the collection bin support frame, and the other end of the collection bin Z-axis adjustment screw is screwed onto the collection height adjustment bracket. By means of the collection bin Z-axis adjustment screw, the collection bin support frame can be displaced in the Z-axis direction relative to the collection height adjustment bracket.

[0020] Further, the collecting bin is connected to the collecting bin support frame through a collecting connecting plate. A long adjusting hole in the X direction of the collecting bin is opened on the collecting connecting plate. The collecting bin is fixedly connected to the long adjusting hole in the X direction of the collecting bin through bolts, and the displacement of the collecting bin in the X direction is adjusted according to the position connected to the long adjusting hole in the X direction of the collecting bin.

[0021] Further, the collecting connecting plate is connected to the turning shaft of the collecting bin, and the turning shaft of the collecting bin is rotatably connected to the collecting bin support frame.

[0022] Further, the collecting connecting plate is sleeved on the turning shaft of the collecting bin through a key shaft, and the relative position of the collecting bin to the turning shaft of the collecting bin is fixed by inserting a Y-direction adjusting key of the collecting bin into the key shaft.

[0028] The design of the quartz sand collecting bin of the present utility model can solve the problem of collecting quartz sand splashed from the quartz crucible melting furnace mold during the production of quartz crucibles with a relatively high degree of automation. The collected quartz sand can reduce the pollution of the surrounding environment, which is necessary for both personnel and quartz sand materials; and the collected quartz sand can be used as poor-quality materials, further saving costs.

[0029] The structural design characteristics of the quartz sand collecting bin conform to the trajectory of the quartz sand splashed from the mold, ensuring that more quartz sand is collected and can flow more smoothly into the collecting cylinder.

[0030] The quartz sand collecting bin can be rotated to a vertical state, which can ensure that all the quartz sand in the collecting bin is poured out, avoiding material pollution caused by residues.

[0031] The quartz sand collecting bin can meet the requirements of different specifications of molds and different qualities of quartz sand through adjustable designs in three directions, increasing the adaptability range of the equipment and indirectly saving costs. Description of the Drawings

Thus, the features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the creation of the present utility model, unless otherwise stated, the meaning of "a plurality" is two or more.

[0041] In the description of the creation of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the creation of the present utility model can be understood through specific circumstances.

[0042] The creation of the present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0043] As Figure 1 and 2 shown, the fly material collection mechanism 5 for quartz sand processing includes a quartz sand collection bin 51;

[0044] The quartz sand collection bin 51 includes a connected quartz sand collection front end 513, a quartz sand collection feed part 511, and a quartz sand collection discharge part 512; the quartz sand collection bin 51 can be integrally formed or assembled by a plurality of shells, as long as the integrity of the collection bin is ensured.

[0045] By designing the bottom of the quartz sand collection bin 51 to be inclined, it can ensure that the quartz sand collected from the collection feed port flows out from the tail opening of the quartz sand collection discharge part 512; or by designing a flip structure, the quartz sand in the quartz sand collection bin 51 can flow out through flipping.

[0046] The opening of the front end 513 of the quartz sand collector forms a collection inlet together with the openings of the quartz sand collection inlet section 511 and the quartz sand collection outlet section 512, and the external shape of the collection inlet matches the external shape of the quartz crucible melting furnace mold 1 from which the pre-generated quartz sand splashes out; the quartz sand collection outlet section 512 is a flared housing to facilitate the outflow of the collected quartz sand.

[0047] The tail opening of the quartz sand collection outlet section 512, and the material entering the quartz sand collection outlet section 512 is discharged through the tail opening.

[0048] The opening height of the quartz sand collection inlet section 511 is greater than the openings of the front end 513 of the quartz sand collector and the quartz sand collection outlet section 512. This is mainly because the quartz sand collection inlet section 511 located in the middle receives more splashed quartz sand with a higher trajectory.

[0049] The quartz sand collection bin 51 is installed at a preset position through the collection bin support frame 552, and the quartz sand collection bin 51 rotates relative to the collection bin support frame 552. One extreme position is perpendicular to the horizontal plane, and the other extreme position is parallel to the horizontal plane.

[0050] It also includes a collection bin rotation shaft 573. The quartz sand collection bin 51 is connected to the collection bin rotation shaft 573. The collection bin rotation shaft 573 rotates with the collection bin support frame 552 by the power provided by the collection bin rotation servo motor 571.

[0051] Since the quartz sand collection bin 51 can rotate, position detection and buffering at the extreme positions are provided to improve the practicality and lifespan of the quartz sand collection bin 51.

[0052] A collection bin horizontal in-place sensor 572 and a collection bin horizontal buffer limit member 574 are installed on the collection bin support frame 552. The collection bin horizontal in-place sensor 572 detects the horizontal extreme position of the collection bin, and the collection bin horizontal buffer limit member 574 is installed at a horizontal extreme movement position of the quartz sand collection bin 51 to provide an elastic buffer force and position support for the quartz sand collection bin 51.

[0053] A collection bin vertical in-place sensor 576 and a collection bin vertical buffer limit member are installed on the collection bin support frame 552. The collection bin vertical in-place sensor 576 detects the vertical extreme position of the collection bin, and the collection bin vertical buffer limit member is installed at a vertical extreme movement position of the quartz sand collection bin 51 to provide an elastic buffer force and position support for the quartz sand collection bin 51.

[0054] The vertical buffer limit member and the horizontal buffer limit member of the collection bin can be spring-based components, or materials with elastic deformation can be laid on the components themselves, as long as they can receive the collection bin and play a role in limiting and buffering it.

[0055] As Figures 3 - 4 shown, the quartz sand collection bin 51 can be adjusted in position in three directions of X, Y, and Z relative to the quartz crucible melting furnace mold 1.

[0056] For the position adjustment in the X-axis direction, as long as micro-adjustment can be achieved, the design structure of this patent is:

[0057] The collection bin is connected to the collection bin support frame 552 through a collection connecting plate. The collection connecting plate is provided with a long hole 581 for adjusting the X-direction of the collection bin. The collection bin is fixedly connected to the long hole 581 for adjusting the X-direction of the collection bin through bolts, and the displacement of the collection bin in the X-direction is adjusted according to the position connected to the long hole 581 for adjusting the X-direction of the collection bin. The collection connecting plate is connected to the collection bin turning shaft 573, and the collection bin turning shaft 573 is rotatably connected to the collection bin support frame 552. When adjustment is needed, as long as the bolts are fixed at the original position of the long hole 581 for adjusting the X-direction of the collection bin and changed, the fine adjustment of the collection bin in the X-direction can be satisfied.

[0058] For the position adjustment in the Y-axis direction, as long as micro-adjustment can be achieved, the design structure of this patent is:

[0059] The collection connecting plate is sleeved on the collection bin turning shaft 573 through a key shaft, and the relative position of the collection bin to the collection bin turning shaft 573 is fixed by inserting the collection bin Y-direction adjustment key 582 into the key shaft.

[0060] The key shaft slides on the collection bin turning shaft 573. After sliding in place, the collection bin Y-direction adjustment key 582 is inserted into the key shaft for fixation, realizing the fine adjustment of the collection bin in the Y-direction.

[0061] For the position adjustment in the Z-axis direction, as long as micro-adjustment can be achieved, the design structure of this patent is:

[0062] The bottom of the collection bin support frame 552 is connected with a collection bin Z-axis adjustment screw 583. The other end of the collection bin Z-axis adjustment screw 583 is screwed on the collection height adjustment bracket 551. Through the collection bin Z-axis adjustment screw 583, the collection bin support frame 552 can displace in the Z-axis direction relative to the collection height adjustment bracket 551.

[0063] By rotating the collection bin Z-axis adjustment screw 583 up and down, the position of the collection bin support frame 552 connected to it can be adjusted, so as to meet the fine adjustment of the collection bin in the Z-axis direction.

[0064] A receiving funnel 53 is provided below the tail opening of the quartz sand collecting and discharging part 512, and the receiving funnel 53 is fixed on the collecting bin support frame 552; the receiving funnel 53 is communicated with the lower collecting bin 56 through a receiving hose 54.

[0065] The receiving hose 54 is fixedly installed on the collecting height adjusting bracket 551. When the collecting bin is displaced in the Z-axis direction, due to its own characteristics and length, the receiving pipe can remain stationary and still maintain its relative position with the lower collecting bin 56 below, ensuring that the collected quartz sand still accurately falls into the collecting bin 56.

[0066] When the quartz crucible melting furnace mold 1 starts processing, splashing quartz sand will be generated. At this time, the quartz sand collecting bin 51 is placed near the mold, and the splashed quartz sand all falls into the quartz sand collecting bin 51.

[0067] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
