Description
Technical field
The utility model belongs to photovoltaic silicon wafer cutting field, is specifically related to a kind of application specific architecture for improvement of collapsing limit end to end.
Background technology
At present, multi-wire saw technology is a kind of conventional silicon chip process technology, and its principle drives mortar abrasive by the steel wire of high-speed cruising, and cut silicon material, in cutting process, mortar can enter silicon material with steel wire and then reach cutting object.But, usually the mortar used mostly is online recycling mortar, along with recycling of mortar, silica flour content in mortar compares off-line mortar can significantly be increased, the mobility of mortar reduces, and is piled up between silicon chip and silicon chip and can not must flows out in time, silicon chip is expanded to both sides, thus it is bad to make the silicon chip of silicon material both sides cause collapsing limit breach because expanding extruding, causes a large amount of product defectses.
Utility model content
In silicon material cutting process, cause silicon stub bar tail to collapse the problem on limit in order to overcoming because mortar mobility reduces, the utility model provides a kind of special-purpose member for improvement of collapsing limit in silicon material cutting process end to end.
The utility model solves the technical scheme that its technical problem adopts: a kind of special-purpose member for improvement of collapsing limit in silicon material cutting process end to end, described special-purpose member is adhered to head and the afterbody of silicon material respectively, and the device be fixed on together with described silicon material for fixing silicon material, the shape of described special-purpose member is cuboid, the length of described cuboid is 156mm, all fall miter angle for the upper surface of described cuboid and each bar limit of lower surface, and the flatness of described upper surface and described lower surface is less than or equal to 0.2mm.
Further, described special-purpose member is adhered to the head of silicon material respectively and afterbody is specially: described special-purpose member is two pieces, wherein the upper surface of a piece or lower surface bonds are in the head of described silicon material, and the upper surface of another block or lower surface bonds are in the afterbody of described silicon material.
Further, the thickness of described special-purpose member is 10mm.
Further, the wide of described cuboid is 73mm-83mm.
Further, the wide of described cuboid is 78mm.
The beneficial effects of the utility model are: head and the afterbody that 1, should be adhered to silicon material for improvement of the special-purpose member collapsing limit in silicon material cutting process end to end, silicon chip are opened to the effect playing suppression to both sides, thus reach the generation that limit is collapsed in reduction end to end; 2, should be 156mm for improvement of the length collapsing the special-purpose member on limit in silicon material cutting process end to end, wide is 73mm-83mm, thickness is 10mm, each corner angle of upper and lower surface are 45° angle, flatness is less than or equal to 0.2mm, this special-purpose member of this size is used to be easy to bonding, and can not due to the sharp generation causing the anomalies such as broken string of corner angle in cutting process.

Detailed description of the invention
As depicted in figs. 1 and 2, a kind of shape of the special-purpose member 1 for improvement of collapsing limit in silicon material cutting process is end to end cuboid, the length of described cuboid is 156mm, wide is 73mm-83mm, preferably, the wide of described cuboid is 78mm, and all fall miter angle for the upper surface 11 of described cuboid and each bar limit of lower surface 12, and the flatness of upper surface 11 and lower surface 12 is less than or equal to 0.2mm.
When line cutting machine cloth gauze, the special-purpose member 1 being arranged at silicon material 2 head-tail is reserved certain thickness, make it not participate in cutting, preferably, the thickness (namely the height of described cuboid) of special-purpose member 1 is 10mm.
As shown in Figure 3, before silicon material 2 cuts, need the head and the afterbody that special-purpose member 1 are adhered to respectively silicon material 2, and the device 3 be fixed on together with silicon material 2 for fixing silicon material, more specifically, special-purpose member 1 is two pieces, and wherein the upper surface 11 of a piece or lower surface 12 are adhered to the head of silicon material 2, and the upper surface 11 of another block or lower surface 12 are adhered to the afterbody of silicon material 2.
A kind of function for improvement of collapsing the special-purpose member on limit in silicon material cutting process end to end of the utility model is as follows: when cutting, because the special-purpose member of silicon material both sides leaves certain thickness, do not participate in cutting, this part does not participate in the special-purpose member cut, an opposite effect power is applied to the tension force that mortar makes silicon chip open to both sides, effectively avoid because mortar mobility is not good, what cause collapses limit phenomenon end to end.
Above embodiment is only illustrate reference of the present utility model, do not form any restriction to the utility model content, obviously under thought of the present utility model, can make multi-form structure modify, but these is all at the row of protection of the present utility model.
