It is referred to as photovoltaic on, abbreviation photovoltaic, core component is solar battery sheet, and its manufacturing process is divided into making herbs into wool-diffusion-quarter
Erosion-PECVD plated films-silk-screen printing-sintering-testing, sorting；Wherein, sintering circuit is the most important procedure of finishing phase,
Its effect is that front side silver paste and back side aluminium paste are formed into alloy with silicon at high temperature to reach good Ohmic contact, so as to export
Carrier, reach the purpose of transmission electric current；At present, the sintering crawler that TPS/DSH agglomerating plants use is nichrome material；
Producer is Wuxi Ai Weisi, and design parameter structure is：Furnace zone length：27m；Furnace zone width：254mm；Thimble spacing：180mm；Top
Pin height：7mm；Thimble angle：79 ° of thimble diameters：1.2mm;However, at present above sintering furnace furnace zone in production application, with
The passage in furnace zone life-span, phenomena such as back surface field thimble print often occurs, scratches, lack；Substantial amounts of BC is caused to reduce piece, due to electricity
Pond piece comes into sintering, leads to not do over again, it is necessary to degradation processing, causes yield to decline and is wasted with cost；Its main cause
Undesirable cause is designed for thimble；Thimble spacing is 180mm；（Width design is partially narrow, and cell piece does not have after reaching on sintering crawler
Enough adjustment spaces, easily hindered by narrow thimble edge top, scratch；Cell piece can be directly run to top when furnace zone is shaken
Back surface field is caused to lack on pin）；Thimble height：7mm；（Cause thimble excessively flat, with the lifting in furnace zone life-span, thimble is all the more
Close to level, the position area that the cell piece back side contacts with thimble becomes big, causes back surface field position to be damaged by thimble contact and lacks
Lose）；Thimble angle：79°（With thimble height similarly）；Thimble diameter：1.2mm;（Cell piece causes after being contacted for a long time with furnace zone
Furnace zone is worn by cell piece edge, and thimble diameter is big, is formed after thimble section more greatly, rear cell piece contacts with thimble to be contacted by point
It is changed into face contact, causes back surface field edge to scratch）.
The content of the invention
The purpose of this utility model is the damage for improving thimble to cell piece back surface field, adjusts every skill of sintering crawler design
Art parameter, the utility model improve above-mentioned bad by the following technical programs：
A kind of furnace zone structure for improving cell piece sintering, including furnace zone, stand-up link, brace, cell piece, sleeve pipe, bar shaped
Groove, thimble；Wherein：That is fixed on the upper surface in described furnace zone is provided with the symmetrically placed thimble of two rows；In each row
Interval between thimble is equal；Cell piece is placed between two described row's thimbles；Each described thimble is by head and the tail
The stand-up link that is fixedly linked, brace composition, the remaining one end of stand-up link, brace upper surface stationary phase with furnace zone respectively
Even；Angle between described stand-up link, brace is 60 degree；The height of described stand-up link is 10 millimeters.
A kind of furnace zone structure for improving cell piece sintering, wherein：Two described on two row's correspondence positions are upright
The distance between connecting rod is 195 millimeters；A diameter of 0.8 millimeter of described brace；Described stand-up link, the cross section of brace
It is circle.
A kind of furnace zone structure for improving cell piece sintering, wherein：The cross section of described brace is that both ends have circular arc
Rectangle；A sleeve pipe is socketed with the upper surface of each described brace；The cross section of each described sleeve pipe is equal
For ellipse；The lower surface of each described sleeve pipe is provided with one of strip groove；One of each described brace
Divide and be inserted in the strip groove of each sleeve pipe；Described sleeve pipe is made up of high temperature ceramic material；Described cell piece is put
Put on the upper surface of two bar casing tubes.
The utility model has the advantages that：In the case of more costs are not put into, it can prevent because sintering crawler makes for a long time
Scratched with caused back surface field, top wound, missing；So as to reduce BC class ratios, ratio of doing over again is cost-effective.
The beneficial effects of the utility model are：The diameter for sintering the brace on thimble reduces, the energy in black silicon sintering process
Allow cell piece to fully absorb sintering heat, avoid because brace diameter greatly caused by thimble position underburnt situation.
