Method, device and device assembly for taking out multiple polysilicon rods

Abstract

The invention relates to a method, a device and a device assembly for taking out polysilicon rods for transfer after the production of the polysilicon rods, in particular to a method, a device and a device assembly capable of taking out a plurality of polysilicon rods at one time, and belongs to the technical field of photovoltaics and semiconductors. For the plurality of polysilicon rods distributed on a plurality of coaxial rings, firstly, the polysilicon rods distributed on the outmost ring are taken out at one time; then, the polysilicon rods distributed on the second outmost circular ring are taken out at one time; and all the polysilicon rods are taken out ring by ring from outside to inside sequentially. The device for taking out the rods comprises a wall and a cavity, and the lower part of the device for taking out the rods is provided with a contact piece for supporting broken polysilicon rods. The method, the device and the device assembly for taking out the rods reduce the risk of contaminating the polysilicon rods in the process of transfer, greatly simplify the production process, reduce the time required for transferring the polysilicon rods, reduce the production period of the polysilicon rods, and solve the problem that operators are easy to scratch by the polysilicon rods simultaneously.

Description

technical field [0001] The invention relates to a method and device for transferring polycrystalline silicon rods after production in the field of photovoltaic and semiconductor technology, and in particular to a method for taking out multiple polycrystalline silicon rods at one time, a rod removing device and a combination of the rod removing device pieces. Background technique [0002] Due to the unique properties of silicon materials, it has become the basis of modern electronics industry and information society. Divided by purity, silicon materials can be divided into metal silicon and semiconductor (electronic grade) silicon; divided by structure, they can be divided into amorphous silicon, polycrystalline silicon and single crystal silicon. Among them, polysilicon is divided into high-purity polysilicon, thin-film polysilicon, ribbon polysilicon and cast polysilicon, and single crystal silicon is divided into zone melting single crystal silicon and Czochralski single ...

AI Technical Summary

Problems solved by technology

There are many defects in the traditional method of removing rods. First, the traditional method of removing rods is to expose the polysilicon rods to the environment, which will cause the polysilicon rods to be polluted by ions, carbon dioxide and other materials in the environment, which will affect the polysilicon rods. The quality of rods; second, the traditional method of removing rods requires manual or mechanical hands to transport polysilicon rods to the next production workshop again and again, and only one pair can be transported at a time. At present, polysilicon hydrogen reduction furnaces are generally designed to be 24 or 18 pairs of polysilicon Rods, for example, a reduction furnace that takes 24 pairs of rods, requires manual or mechanical hands to transport up to 24 times, which is not only cumbersome to operate, but also takes a long time to take out the rods; The bottom plate of the reduction furnace can be cleaned and the reaction of the next furnace can be carried out. Because the traditional rod extraction method takes a long time, it will affect the reaction of the next furnace, which prolongs the production cycle; the fourth . Since polysilicon is a very sharp material, when the rod is taken out manually, the silicon rod is easy to break and scratch the operator
