Description
[technical field]
The utility model relates to high voltage silicon rectifier stack splitting equipment technical field, especially relates to a kind of special segmenting device of high voltage silicon rectifier stack.
[background technology]
Known, existing high voltage silicon rectifier stack segmentation has following several method:
The first, mechanical scribing segmentation, this is more original silicon chip dividing method, maximum fractionation thickness 1.2mm, when splitting single silicon chip, effect can manage it, but yield rate is about 85%, just not too easily split for thicker high voltage silicon rectifier stack disk, the silicon stack split exactly, edge is very irregular, easily collides with out and collapses limit, and affecting follow-up encapsulation, yield rate also only has 65-70%; The second, cylindrical blade cuts, although the thickness of cutting can reach 2cm, efficiency comparison is low, and cutter seam loss (2-3mm) is larger, every sheet circular high voltage silicon stack effectively utilizes area to decrease about 30%, and yield rate omits height than scribing machine can reach about 85%; Three, laser cutting, efficiency increases, but P or the N face of high temperature to the two ends at high voltage silicon rectifier stack edge of laser easily causes sintering hole in cutting process, and to the metal level in silicon stack sintering process cause fusing and silicon stack edge formed short circuit, make silicon stack withstand voltage not or punctured by electric leakage, therefore have impact on the production of enterprise greatly.
[utility model content]
In order to overcome the deficiency in background technology; the utility model discloses a kind of special segmenting device of high voltage silicon rectifier stack; the utility model by arranging alignment pin and the first frock in the second frock; first frock arranges block, buffer board, carrier board and baffle; again by being fixed between baffle and carrier board by silicon stack disk, reach the object of high efficiency cutting silicon stack disk with this.
In order to realize described utility model object, the utility model adopts following technical scheme:
A kind of special segmenting device of high voltage silicon rectifier stack, comprise the first frock, second frock, alignment pin, block, buffer board, carrier board and baffle, second frock upper side is provided with alignment pin and the first frock, second frock is provided with two alignment pins, the middle part of described first frock is provided with prevents falling screw hole, anti-surrounding of falling screw hole is provided with holding screw hole, first frock is inserted by screw and is prevented that falling screw hole makes the first frock be connected with the second frock with holding screw hole, the side of the first frock is provided with block, block is placed between two alignment pins of the second frock, the upper side of the first frock is provided with buffer board, buffer board is provided with carrier board, carrier board is provided with baffle.
Described buffer board is that resin material is made.
Described first frock is cylindrical structure, prevents falling the central part that screw hole is arranged on cylinder, along preventing that falling screw hole surrounding is equidistantly provided with at least three holding screw holes.
Described alignment pin is cylindrical structure, and alignment pin is arranged on the lateral surface of the first frock, and alignment pin and the second frock are connected to a fixed.
Owing to have employed technique scheme, the utility model has following beneficial effect:
The special segmenting device of a kind of high voltage silicon rectifier stack described in the utility model, comprise the first frock, the second frock, alignment pin, block, buffer board, carrier board and baffle, by arranging alignment pin and the first frock in the second frock, first frock arranges block, buffer board, carrier board and baffle, again by being fixed between baffle and carrier board by silicon stack disk, reach the object of high efficiency cutting silicon stack disk with this; The utility model is practical, and segmentation precision is high, has not only significantly saved silicon material, and yield rate height very, therefore greatly improves operating efficiency, facilitates the development of enterprise.
