Abstract
The utility model relates to a silicon rod provided with a chamfering guide strip. The guide strip is arranged on the side surface of the silicon rod, and the side surface is the surface which is in contact with a fed steel wire firstly. The guide strip is adhered on the first side surface of the silicon rod, the adhesion position of the guide strip is parallel to a ridge at the chamfered part of the silicon rod; and the two end surfaces of the guide strip are parallel to the two end surfaces of the silicon rod. The silicon rod provided with the chamfering guide strip, disclosed by the utility model, can enable the cutting of a wire net to be more uniform during the processing of the silicon rod, and reduce the phenomena of edge chips, thick and thin chips, broken chips and the like.
Description
Technical field
The utility model relates to a kind of silicon rod, and particularly a kind of silicon rod that is provided with the chamfering gib block, belong to silicon rod manufacture field in the production of solar energy silicon rod.
Background technology
At present, silicon rod is in cutting process, and gauze is unstable owing to entering cutter, and steel wire easily skids, thereby causes thickness sheet, sliver, and severe patient can cause line ball, broken string; Due in cutting process, the cutting power of carborundum changes, the variant variation of granular size, add when steel wire enters cutter and the band slurry amount of steel wire when entering crystal bar relatively large, this kind phenomenon easily causes the reciprocal silicon rod uneven thickness of the feeding of steel wire; When gauze is fed into certain depth, produce the line bow, silicon rod side and silicon rod make easy generation the in chamfering place collapse the limit in the face of the stressed maximum of face handover region of gauze, and these problems affect the cut quality of silicon rod always.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of silicon rod that is provided with the chamfering gib block, can make in silicon rod processing the gauze cutting more even, reduces and collapses the phenomenons such as limit sheet, thickness sheet, sliver.
Above-mentioned purpose of the present utility model is to realize by such technical scheme: a kind of silicon rod that is provided with the chamfering gib block, and the side of described silicon rod is provided with gib block, and described side is the face that at first the steel wire feeding contacts.
Described gib block is bonded on the first side of silicon rod, and the bonding location of gib block is parallel with the rib at silicon rod chamfering place; Described gib block both ends of the surface are parallel with the silicon rod both ends of the surface.
Described gib block is trapezoidal, and is trapezoidal thick: 1 ~ 10mm, trapezoidal shorter bottom side length 1 ~ 156mm.
Described gib block is any one in PPS, PMMA, PEEK, PET, PVC, PPO, PS, PC, PES or PASU general engineering plastic.
Described gib block is at least one.
A kind of silicon rod that is provided with the chamfering gib block of the utility model solves some quality problems that occur in silicon rod processing better, as: thickness sheet problem; Collapse the limit; Sliver; Fragment makes as far as possible steadily equidistant cutting silicon rod of gauze.

The specific embodiment
As Fig. 1 ~ shown in Figure 4, a kind of silicon rod that is provided with the chamfering gib block, the first side 2 of described silicon rod 1 is provided with gib block 3, the face that at first described the first side 2 contacts for the steel wire feeding.
Described gib block 3 is bonded on the first side 2 of silicon rod 1, and the rib 4 at the bonding location of gib block 3 and silicon rod 1 chamfering place is parallel; Described gib block 3 both ends of the surface are parallel with silicon rod 1 both ends of the surface.
Described gib block 3 is trapezoidal, and is trapezoidal thick: 1 ~ 10mm, trapezoidal shorter bottom side length 1 ~ 156mm.
Described gib block 3 is any one in PPS, PMMA, PEEK, PET, PVC, PPO, PS, PC, PES or PASU general engineering plastic.
Described gib block 3 is at least one.
A kind of silicon rod that is provided with the chamfering gib block of the utility model in cutting process, during the cutting certain depth, was cut chamfering, gauze
5Formation line bow, at first through the gib block 3 of the first side 2, gib block 3 is softer with respect to silicon rod 1 for steel wire, and steel wire can first be determined line-spacing, begins cutting silicon rod 1 after cabling is steady, so, just can reduce the situations such as thickness sheet, off-chip.
A kind of silicon rod that is provided with the chamfering gib block of the utility model, in cutting process, the steel wire band slurry amount of the second side 6 of silicon rod 1 is relatively large than the band slurry amount of the side of silicon rod 1 middle part and silicon rod 1, and carborundum is also sharper, and silicon rod 1 integral cutting is inhomogeneous.After placing gib block, at first steel wire cuts gib block 3, then passes through the glue-line filtration of 1 of gib block 3 and silicon rod, makes carborundum consistent to the cutting effect of whole silicon rod, in order to reduce the mass loss that causes due to the surperficial became uneven of silicon rod.
A kind of silicon rod that is provided with the chamfering gib block of the utility model, in cutting process, when switching to certain depth, gauze 5 can produce the line bow, silicon rod 1 circular arc place is stressed larger, the too fast meeting of linear speed makes silicon rod 1 smooth surface of cutting, but can be at the circular arc place or the first side 2 produce and collapse the limit, after placing gib block 3, again because the impact of line bow, in the steel wire high-speed motion, at first contact the bonding gib block 3 in the second side 6, when steel wire switches to the first side 2 of silicon rod, every kinematic parameter of steel wire is more stable, will damage: collapse limit, thickness etc. and be transferred on gib block 3.
As the above-mentioned limit branch problem that collapses, the surperficial became uneven problem of the silicon rod 1 that produces when steel wire is cut silicon rod 1 unanimously forwards on gib block 3, and when steel wire switched to silicon rod 1, line-spacing was more stable, and band sand amount is suitable, has avoided the silicon rod TTV situation not up to standard of cutting.
When depth of cut arrives the upper edge of gib block 3, effect with the gib block 3 of chamfering is to make steel wire be transitioned into silicon rod 1 body by gib block 3 stably, so avoids producing to get because steel wire is transitioned on silicon rod 1 by right angle end moment of gib block 3 suddenly quality problems.
