Preferably, the width of described cutting gaps is 5 millimeters.
Preferably, between adjacent two lines of cut of described cutting group, form cutting gap, each described line of cut is uniform successively along the bearing of trend of the axis of described drive roll with described cutting gap.
Preferably, the width of described cutting gap is 334 microns.
Preferably, described line of cut is steel wire.
Relative above-mentioned background technology, silicon chip cutting assembly provided by the utility model, comprise the drive roll and the driven voller that be arranged in parallel, be arranged with some cutting groups on described drive roll and described driven voller, described cutting group comprises some lines of cut that be arranged in parallel, the bearing of trend of the bearing of trend of described line of cut and the axis of described drive roll is perpendicular, forms the cutting gaps matched with silicon ingot splicing place between adjacent two cutting groups.In the course of work, described cutting gaps can effectively be avoided described line of cut to enter silicon ingot splicing place and produce unloaded wearing and tearing, avoid the generation of the inoperative broken string phenomenon that causes because of zero load wearing and tearing, effectively reduce the outage of described silicon chip cutting assembly, and make the corresponding raising of its working (machining) efficiency.
