Automatic feeding device during crystal material processing

Abstract

The invention relates to an automatic feeding device during crystal material processing, relating to auxiliary devices of crystal processing. A crystal bar storage mechanism for material preparation in early stage is arranged on one side of a distribution feeding mechanism for interval delay, a plurality of mutually relative hook teeth (22) are arranged at outer edges of at least two crystal bar conveying wheels (17), a ratchet wheel (15) arranged on a shaft is connected with a control system of the distribution feeding mechanism, and the control system of the distribution feeding mechanism drives the ratchet wheel to make the hook teeth on the crystal bar conveying wheels drive crystal bars of the crystal bar storage mechanism for the material preparation in early stage to move onto a crystal bar discharge plate (2) for guiding materials on the other side of the distribution feeding mechanism. According to the automatic feeding device disclosed by the invention, silicon cores are conveyed to the distribution feeding mechanism for the interval delay by the crystal bar storage mechanism for the material preparation in the early stage, and the distribution feeding mechanism for the interval delay realizes the interval delay conveyance of the crystal bars onto the crystal bar discharge plate for guiding the materials by the control system of the distribution feeding mechanism, thus the defect that labors need to keep an eye on the production field for a long term in the traditional processing method is prevented.

Description

【Technical field】 [0001] The invention belongs to auxiliary equipment for crystal processing, in particular to a device for automatically feeding crystal materials during grinding, in particular to an automatic feeding device for processing crystal materials. 【Background technique】 [0002] At present, silicon core lapping technology is a very important technology in the process of producing polysilicon by the Siemens method, and it is mainly used in a link of polysilicon production, that is, the reduction reaction process; the principle of the reduction reaction process is: reduction reaction It is carried out in a closed reduction furnace. Before loading the furnace, silicon cores are used to overlap several closed loops in the reduction furnace, which is the "bridge" in the jargon; each closed loop is composed of two vertical silicon cores. Core and a horizontal silicon core; two vertical silicon cores of each closed circuit are respectively connected to two electrodes on...

Problems solved by technology

[0004] When realizing the above cited patent application technology, one horizontal silicon core and two vertical silicon cores are connected through bridging technology, wherein the two ends of the horizontal silicon core are cut into a certain shape by grooving or grinding, and then ground into a certain shape The lapping of the grinding surface corresponds to the groove part to form the final lapping method; however, the aforementioned lapping technology must pre-process the horizontal silicon core or the vertical silicon core. According to the current processing capacity, the processing of the horizontal silicon core Or when the silicon core is erected, it is required that the staff must be guarded at all times during the processing. When a silicon core is processed, the staff must first stop the machine in order to prevent safety accidents, and manually take out the processed silicon core. Then install a new silicon core. At the same time, in order to make the grinding position of the silicon core uniform during grinding, the staff must continuously adjust the silicon core. After the adjustment, restart the equipment for reprocessing , because this method is subject to a lot of human interference factors, and when replacing the silicon core, it is necessary to stop the machine to pick and place the silicon core and adjust the position of the silicon core, which will inevitably greatly reduce the processing efficiency and increase the production cost; Conducive to the realization of energy saving and environmental protection

[0005] The inventor has not found a mechanized automatic feeding device for horizontal silicon cores or vertical silicon cores through searching, that is to say, there is no relatively complete automatic feeding device for mechanized horizontal silicon cores or vertical silicon cores.
