Description
Technical field
The utility model relates to a kind of sintering crawler, especially a kind of structure-improved of solar cell sintered furnace band.
Background technology
Sintering is one critical process that solar cell makes.The object of sintering is the slurry after serigraphy on dry silicon chip, and the organic component of after-flame slurry, makes slurry and silicon chip form good Ohmic contact.The object of aluminium paste sintering is that the organic solvent in slurry is volatilized completely, and forms intact alusil alloy and aluminium lamination.The alusil alloy that back surface field is formed after sintering, aluminium is that it can reduce the few sub-compound of metal and silicon junction as the doping of P type in silicon, thus improves open-circuit voltage and short circuit current, improves ultrared response.The inequality of being heated of local may cause bag with heat radiation inequality, and serious meeting plays aluminium pill, forms high recombination region thus reduces battery conversion efficiency.
Summary of the invention
For the weak point existed in the problems referred to above, the utility model provides a kind of structure-improved improving the exterior quality of solar battery sheet and the solar cell sintered furnace band of conversion efficiency.
For achieving the above object, the utility model provides a kind of structure-improved of solar cell sintered furnace band, comprise sintering furnace conveyer belt (1) and two bracing frames (3), two support frames as described above (3) are separately positioned on the left and right sides of described sintering furnace conveyer belt (1), support frame as described above (3) is oblique Eight characters shape, and the strong point (4) of support frame as described above (3) support cells sheet (2) is located at described cell piece (2) edge not to be had on the position of slurry;
2mm is spaced apart between the top surface of described cell piece (2) and described sintering furnace conveyer belt (1).
The structure-improved of above-mentioned solar cell sintered furnace band, wherein, the length of described cell piece (2) is less than the length between the top end of two support frames as described above (3).
The structure-improved of above-mentioned solar cell sintered furnace band, wherein, spacing between the top end of two support frames as described above (3) is 175mm, distance between the bottom inside of two support frames as described above (3) is 99mm, and the distance between the bottom outside of two support frames as described above (3) is 205mm.
The structure-improved of above-mentioned solar cell sintered furnace band, wherein, support frame as described above (3) supports the side of described cell piece (2) and the angle (a) of described sintering furnace conveyer belt (1) is 15 ° ~ 30 °.
The structure-improved of above-mentioned solar cell sintered furnace band, wherein, the outside of support frame as described above (3) is higher than the inner side of support frame as described above (3).
Compared with prior art, the utility model has the following advantages:
1, do not have on the position of slurry because the strong point of bracing frame support cells sheet is located at cell piece edge, therefore, avoid because the strong point place sintering that inequality causes that is heated is bad in sintering process, to improve exterior quality and the conversion efficiency of solar battery sheet;
2, because the interval between cell piece and the top surface of sintering furnace conveyer belt is only 2mm, therefore, shorten the interval between cell piece and sintering furnace conveyer belt, improve acceptance rate and the conversion efficiency on cell piece surface better;
3, after the shape of bracing frame being set as oblique splayed configuration, cell piece does not need the both sides of printing to contact with splayed configuration bracing frame, has stopped cell piece and has been polluted, and promotes cell piece quality;
4, because bracing frame adopts nickel alloy material to make, therefore, the heat resistance and service life that make band can be improved.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
Main Reference Numerals is described as follows:
1-sintering furnace conveyer belt; 2-cell piece; 3-bracing frame; The 4-strong point.
Detailed description of the invention
As shown in Figure 1, furnace zone of the present utility model comprises the left and right sides that sintering furnace conveyer belt 1 and two bracing frames, 3, two bracing frames (3) are separately positioned on sintering furnace conveyer belt 1, and cell piece 2 is supported on sintering furnace conveyer belt 1 by two bracing frames 3.Wherein, bracing frame 3 is oblique Eight characters shape, and the strong point 4 of bracing frame 3 support cells sheet 2 is located at cell piece 2 edge not to be had on the position of slurry.Doing so avoids because the strong point place sintering that inequality causes that is heated is bad in sintering process, to improve exterior quality and the conversion efficiency of cell piece.
The length of cell piece 2 is less than the length between the top end of two bracing frames 3.Wherein, the length of cell piece 2 is D` is 156mm.
The bracing frame 3 of oblique Eight characters shape is divided into two, left and right, adopts nickel alloy material to make, and is welded on the arranged on left and right sides of sintering furnace conveyer belt 1 respectively.In addition, the outside of bracing frame 3 is higher than the inner side of bracing frame 3.Space D between the top end of two bracing frames 3 is 175mm, and the distance d between the bottom inside of two bracing frames 3 is 99mm, the distance d` between the bottom outside of two bracing frames 3 is 205mm.
The side of bracing frame 3 support cells sheet and the angle a of sintering furnace conveyer belt 1 can not be too little, in order to avoid the bracing frame below cell piece too closely has influence on the sintering quality of back surface field by cell piece aluminium back surface field.Angle a is also not easily excessive, because vibrations battery slice, thin piece is easily from landing bracing frame in transmission process.Generally this angle is set between 15 ° ~ 30 °.
When the furnace zone of the edge supports for solar cell sintering that the utility model provides uses, cell piece 2 is sent to its front edge after on sintering furnace conveyer belt 1 and first touches bracing frame 3, the acting in conjunction relying on the frictional force of the strong point 4 on bracing frame 3 and front road conveyer belt to advance continues to forward, the bracing frame that in this process, cell piece can continue to touch below, until whole cell piece is fallen on conveyer belt completely, is supported by bracing frame and drives it to advance.
Because the interval between cell piece 2 and the top surface of sintering furnace conveyer belt 1 is only 2mm, therefore, shorten the interval between cell piece and sintering furnace conveyer belt, improve acceptance rate and the conversion efficiency on crystalline silicon battery plate surface better.
The foregoing is only preferred embodiment of the present utility model, is only illustrative for invention, and nonrestrictive.Those skilled in the art is understood, and can carry out many changes in the spirit and scope that invention claim limits to it, amendment, even equivalence, but all will fall in protection domain of the present utility model.
