Description

Technical Field

[0001] The invention belongs to the field of photovoltaics and semiconductors, and in particular relates to automatic forming control equipment for a quartz crucible. Background Art

[0002] Quartz crucible is a subdivided product of quartz glass products. It is made of high-purity quartz sand through mold shaping and high-temperature production using the arc method. It has the characteristics of high temperature resistance, long service life, and high purity. Quartz crucible is mainly used as an auxiliary consumable for the drawing of high-purity single crystal silicon rods for semiconductors. It is a key disposable consumable for containing molten silicon liquid during the drawing 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 silicon growth (semiconductor quartz crucibles and photovoltaic single crystal silicon growth quartz crucibles). In recent years, with the vigorous development of the photovoltaic and semiconductor industries, the demand for the output of quartz crucibles has also increased year by year, and at the same time, higher requirements are placed on the quality of quartz crucibles and their production processes.

[0003] The quartz crucible needs to be stacked with quartz sand of different qualities in each layer under high temperature. The quality of the added quartz sand also varies. The location and stacking method will also change due to the different shapes of the inner wall and bottom of the quartz crucible. Due to this complex process requirement, the existing quartz crucible production method on the market is generally purely manual.

[0004] Workers work continuously and with high concentration in a high-temperature environment to prevent processing errors, environmental impurities and other problems. For example, if impurities fall into the crucible during processing or the thickness is uneven during the stacking process, the entire quartz crucible will become scrapped. The current market price of quartz sand is expensive, and the scrap rate increases, which in turn increases the cost of the entire quartz crucible and cannot meet the market's positioning requirements for quartz crucibles.

[0005] How to replace manual labor in the quartz crucible manufacturing process is one of the important problems to be solved to improve the automation level of the entire quartz crucible manufacturing process.

[0006] It can automatically stack quartz sand and shape quartz crucibles in a high-temperature environment. It can adapt to the processing of quartz sand of different qualities in each stacking layer without contamination. It can adapt to the processing requirements of different shapes in different positions such as the side wall and inner bottom of the quartz crucible, and can also improve the qualified rate of the finished products after adaptive processing. Therefore, how to maintain the stable operation of the machine during the adaptive process is also one of the important problems to be solved. Summary of the invention

[0079] like Figure 4-5 As shown, the molding lifting mechanism 45 can make the scraper assembly leave the mold or enter the mold for processing, so the lifting mechanism has various forms such as rails, belts, and gears. There are many options on the market, but the preferred mechanism of this patent is more stable, which includes a molding lifting servo electric cylinder 451, and the molding lifting servo electric cylinder 451 is fixed on the molding lifting frame 453.

The molding lifting positioning pin 456 is plugged and pulled out of the molding lifting positioning hole 4411 through the lifting and lowering of the molding translation mechanism 44.

[0081] Or, the movable end of the forming lifting guide shaft 452 on the forming lifting base 454 is connected to the forming rotating mechanism 43, and a scraper assembly is installed on the forming rotating mechanism 43.

A forming lifting mechanism 45 is installed on the forming translation mechanism 44 and provides translational force for the forming lifting mechanism 45.

[0086] Here, the scraper assembly is shown to be installed on the molding rotating mechanism 43, and the molding rotating mechanism 43 is installed on the molding translation mechanism 44. The molding lifting mechanism 45 drives the molding rotating mechanism 43 and the molding translation mechanism 44 to lift and lower together.

[0087] When the molding lifting servo electric cylinder 451 drives the molding lifting base 454 to rise, the molding translation base 441 connected to it through the molding lifting guide shaft 452 also moves upward, and the molding rotating base 431 slidingly connected to the molding translation base 441 can be displaced with the molding translation base 441 through the action of the molding translation servo electric cylinder 443, thereby driving the molding rotating mechanism 43 and the scraper assembly to translate, and the molding rotating mechanism 43 independently acts to rotate the scraper assembly.

[0088] Working principle:

[0089] The original position automatic control device is outside the mold. After the scraper assembly is lifted by the molding lifting mechanism 45, the molding translation mechanism 44 drives the scraper assembly to the top of the mold. The molding rotation mechanism 43 rotates the corresponding scraper assembly to the right position. The molding lifting mechanism 45 descends to the original position. When the sand starts to be thrown into the mold, the scraper assembly is close to the position where the sand needs to be scraped and accumulated. The mold rotates and acts continuously, and finally the initial mold of the quartz crucible is produced.

[0090] When processing the bottom of the mold, due to the "L"-shaped scraper body structure design in the scraper assembly, the quartz sand can be continuously moved to the middle, so that the bottom can be scraped and smoothed without any excess waste sand.

[0091] The molding lifting mechanism 45 and the molding rotating mechanism 43 are both provided with positioning structures, which can ensure that when the quartz crucible is processed, the entire molding control device is more stable and will not deviate, thereby ensuring the flatness of the sand scraping during the processing.

[0092] When the corresponding displacement is completed, the positioning structure starts to work, and the molding rotation positioning pin 433 is extended and inserted into the molding rotation positioning hole 437 to fix the molding rotation mechanism 43 and the scraper assembly;

[0093] The molding lifting positioning pin 456 also extends out and is inserted into the molding lifting positioning hole 4411 to fix the molding lifting mechanism 45 and the molding scraper assembly 41 .

[0094] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
