Abstract
The invention discloses a polycrystal slicing method for improving the silicon rod slicing yield and relates to the technical field of polysilicon rod cutting. The method comprises the following steps of: respectively sticking a resin strip with a width of 2.8mm on the left surface and the right surface of a polysilicon rod which is contacted with a steel wire; and then putting the polysilicon rod on a slicing machine for slicing. According to the polycrystal slicing method, in the polysilicon rod slicing process, because the two resin strips with the width of 2.8mm are respectively stuck on the left surface and the right surface of the polysilicon rod, the resin strips have good fixing effect on the steel wire during cutting, so that the instability of the steel wire during cutting feed is greatly reduced, influences on cutting, which are caused by factors of the instability, are completely stopped, and the yield of the polysilicon rods is effectively improved.
Description
Technical field
The present invention relates to the cutting technique field of polycrystalline silicon rod.
Background technology
It was three steps that the cutting process of polycrystalline silicon rod is divided into: feed, cut, go out cutter, feed is an of paramount importance step in these three processes.
Steel wire on home roll after the full-automatic startup of machine is in high-speed motion state; So the steel wire on this time home roll is a kind of utmost point unsure state; And the decrease speed of silicon rod is relatively slow during feed; If when silicon rod contacts the stressed specification of silicon rod later on own with steel wire error is arranged, promptly can cause the steel wire discontinuity of silicon rod both sides.If steel wire contacts with silicon rod and (is feed) when carrying out opening and just might causes the thin edge sheet and collapse the yield rate that the limit influences silicon rod in this case.
For avoiding the generation of this situation, in existing production process, technology is reformed and innovated, the decrease speed when accelerating the silicon rod cutting, but the stability of this method in cutting process is also not obvious, can not fundamentally solve the problem that exists of producing.
Summary of the invention
The object of the invention is to reduce destabilizing factor in the production, improves the polycrystalline dicing method of the yield rate of silicon rod.
The resin streak that it is 2.8mm that the present invention pastes a width respectively on the left and right two sides of the polycrystalline silicon rod that contacts with steel wire earlier places on the slicer then and cuts into slices.
Because in the polycrystalline silicon rod slicing processes; Be stained with the resin streak of two 2.8mm respectively in the two sides, the left and right sides of polycrystalline silicon rod; This resin streak can play good fixed effect to steel wire when cutting; Greatly reduce the unstability of steel wire when feed, stop these factors fully, effectively raise the yield rate of silicon rod the influence that cutting causes.
The specific embodiment
The resin streak that to paste a width respectively on the left and right two sides of the polycrystalline silicon rod that contacts with steel wire be 2.8mm places polycrystalline silicon rod on the slicer then and cuts into slices.
Claims (1)
1. improve the polycrystalline dicing method of silicon rod section yield rate, it is characterized in that pasting a width respectively on the left and right two sides of the polycrystalline silicon rod that contacts with steel wire earlier the resin streak that is 2.8mm, place on the slicer then and cut into slices.
