Description
Technical field
This utility model is with regard to polysilicon processing special cutting device field, more particularly to a kind of diamond wire crystal ingot evolution
Machine.
Background technology
Polycrystal silicon ingot need after forming by a firing through evolution, block, flour milling chamfering, the technique such as section make photovoltaic
Battery.The evolution of crystal ingot is the first procedure of overall processing process, is that large-scale crystal ingot is cut into small cuboid.At present most
The many user's grid lines of ripe, modal evolution equipment are cut from top feed, and the working area of netting twine saw is to be mutually perpendicular to simultaneously
Several lines of cut in Different Plane are constituted, and do not have 4 netting twines to constitute a grid, and when equipment runs, cutting wire is driven to be cut
Silicon ingot is cut, after the completion of cutting, a small cuboid crystal ingot in the grid of netting twine composition, is just formed.
Netting twine cuts used cutting mode and is divided into mortar wire cutting and Buddha's warrior attendant wire cutting.
Before the diamond wire polycrystal silicon ingot evolution equipment cutting for commonly using at present, first by one pull-out of diamond wire, and across
Tens guide wheels form netted.As the surface feed from crystal ingot, the span of gauze are big, the line bow for causing is just very big, makes
The time for obtaining bracing wire bow increases, so that cutting efficiency is low.The gauze of large span easily leaves cut in cutting surfaces again,
Increase follow-up work amount.In addition, diamond wire used is thinner, across tens guide wheels, reciprocating motion easily causes broken string, once
Broken string, thread-changing difficulty are big, take.And crystal ingot upper surface has many Hard Inclusions, gauze skew is easily caused, affect processing chi
It is very little.
Newest cutting mode is from crossing feed, as the height of polycrystal silicon ingot is typically in 400mm or so, G6 polysilicons
The length and width of ingot has 1000mm or so, and cross feed the wheelbase being greatly reduced between 2 cutting guide wheels, reduces line bow,
Improve cutting efficiency.But this kind of evolution equipment needs for crystal ingot to be rotated by 90 ° common cutting 2 times, when mechanical hand removes to capture crystal ingot,
Paw needs to stretch into crystal ingot bottom, for the stability for ensureing to capture, the amount of stretching into and paw thickness of paw certainly will be increased, this
Sample just brings 2 problems：1. the part crystal ingot bottom that paw can extend into does not support, and the easy chipping in cutting is dropped；
2. the thickness of workbench, after increasing paw thickness, certainly will be increased, so as to indirectly increased the wheelbase between cutting guide wheel, drop
Low cutting efficiency.
Meanwhile, crystal ingot is cut into a plurality of strip by the excavation machine of mode of crossing feed, first time feed, and second feed again will
Strip cuts square.What is taken at present is that cutting gauze is vertically arranged, so in second feed, due to the presence of line bow,
Line of cut can pull out 2 entries on crystal ingot, cut lengths so be easily caused at two strip alternatings uncontrollable and collapse
Side scene occurs, so as to affect cut quality.
