Description

A kind of excavation machine silicon rod holds out against clamp structure

Technical field

This utility model relates to a kind of squaring silicon bar equipment, is specifically related to a kind of excavation machine silicon rod and holds out against clamp structure.

Background technology

At present, the attention utilized green regenerative energy sources along with society and opening, photovoltaic solar power field is increasingly paid attention to and is developed.In field of photovoltaic power generation, solaode is used to convert solar energy into electrical energy realization generating, commonCrystal silicon solar energy batteryBeing to make on the high-quality silicon chip of thickness 160 ~ 200 μm, this silicon chip is formed by multi-wire saw cutting after the silicon ingot of lifting or casting.

The Making programme of existing silicon chip, the most first being lifted by crisp for polysilicon shape material is silicon single crystal rod, then uses excavation machine to carry out evolution；Now, cutting mechanism along silicon rod length direction feeding and cuts out four planes the most parallel in silicon rod circumference so that silicon rod is overall in class cuboid；After evolution, then use multi-line slicer along its length the silicon rod after evolution to be cut into slices, obtain required silicon chip.

Wherein, existing excavation machine, it it is all the structure design that disposably can complete many squaring silicon bar cuttings, the such as industry normally used Mellberg company, Chongqing four and brilliant work, Chong Qingyuan open, Liancheng, Dalian, the squaring silicon bar machine of production such as enter Shanghai day, it is possible to disposably complete the cutting evolution to 16 silicon rod.But this existing squaring silicon bar machine, although cutting mechanism primary feed can complete the cutting of many silicon rods, but owing to silicon rod radical is more, in cutting mechanism, line of cut needs to turn to through a lot of rollers (runner) when arranging cabling, when making its work, energy loss is relatively big, reduces cutting efficiency, in order to ensure cutting effect, cutting mechanism feed speed is the slowest, typically can only achieve 1.3 ~ 3.0mm/min.Therefore integral cutting efficiency reality is the highest, and in order to ensure to cut stability, it is typically only capable to realize the squaring silicon bar within 500mm length.Meanwhile, the silicon rod that the microtome that after squaring silicon bar, corresponding subsequent slice processes generally also is only applicable within 500mm length is cut into slices, it is possible to ensure chipping qualities.

But development and the maturation of technology along with current photovoltaic art, existing relatively advanced multi-line slicer, can be applicable to the slicing treatment of longer silicon rod, owing to when silicon rod is cut into slices in microtome, the waste material of partial-length can be scrapped in two ends, therefore generally silicon rod length is the longest, the whole efficiency of microtome just can be the highest.So for those skilled in the art, it is necessary to research and develop a kind of excavation machine that can be applicable to longer squaring silicon bar so that it is be obtained in that longer evolution silicon rod, to improve the cutting efficiency of subsequent slice machine, reduce the holistic cost that silicon chip produces.

In order to solve the problems referred to above, applicant once devised the single excavation machine of a kind of silicon single crystal rod and had applied for the patent of ZL201520832200.3, this excavation machine, including support, the silicon single crystal rod fixed mechanism being fixedly installed on support, cutting mechanism and rafting line mechanism；Described cutting mechanism include cutting head, be arranged on cutting head multiple for tensioning line of cut cut length cutting wheel, multiple transition directive wheel, the most a set of tensioner for tensioning line of cut and line of cut for realizing transition or guiding, transition directive wheel, tensioner and cutting wheel are upper and two ends connect back to rafting line mechanism around being connected on for line of cut, it is characterized in that, described silicon single crystal rod fixed mechanism is used for fixing single silicon rod, and described cutting head is connected with feed mechanism and can lean on the feed mechanism control realization evolution to silicon rod.This utility model has simple in construction, and cutting efficiency is high, it is possible to the advantage realizing the cutting of longer silicon single crystal rod, it is possible to obtain longer evolution silicon rod, to improve the cutting efficiency of subsequent slice machine, reduces the holistic cost that silicon chip produces.

But in this silicon single crystal rod single evolution equipment, there is also following defect to need to consider to solve: 1, realize silicon rod and hold out against in fixing device, rely on two mounting seats being fixed on pedestal and in a mounting seat, constitute the stationary gripping part in movable clamping part and another mounting seat by hydraulic jack coordinate and realize silicon rod and hold out against, hold out against process control and accuracy is poor, after rotating to facilitate evolution after the structure of this hydraulic cylinder clamping simultaneously being difficult to set up silicon rod clamping cutting again, unload the functions such as top rim charge.2, after evolution cutting, the rim charge under cutting cannot individually discharging.3, in cutting head structure, concordance is poor causes cutting accuracy poor for each cutting wheel.4, after cutting, rim charge directly drops easy other components of impact damage equipment or injure workman.5, relying on before and after cutting and manually load and unload material, operation easier is big, and man efficiency is low.
