The utility model discloses a slicer improvement guide pulley through addding the steel core extension, has prolonged guide pulley working face length greatly, follows original 880mm and increases to 960mm, and wherein effective working face length reaches 950mm, and the hilted broadsword section is multiplicable 380, reaches 2680, and the productivity increases by 16.5 percent, guarantees the quality of silicon chip cutting simultaneously, has improved the utilization ratio of copper wire and mortar liquid, 30, 000 left and right sides of every month multiplicable productivity in the separate unit slicer, greatly reduced monolithic manufacturing cost.
Description
Technical field
The utility model relates to polysilicon microtomy field, is specifically related to a kind of slicer improvement guide wheel.
Background technology
The multi-wire saw technology of cutting polysilicon chip is process technology more advanced in the world at present.In cutting process, steel wire is by the guiding of directive wheel, and commutation, guide wheel is formed a bracing cable net, and silicon rod is at a slow speed by being just cut into silicon chip after gauze.
The conventional slicer guide wheel of current silicon chip of solar cell industry slicing process, inside is steel core, and outer surface is coat, be convenient to process wire casing, guide wheel face length is 880mm, and the effective length once can cutting silicon ingot is 820mm, and silicon chip theoretical value is 2300.Current silicon chip of solar cell industry competition is fierce, product be made to have certain competitiveness in market, need the quantity and quality improving constantly product, effective production control cost.Therefore, the slicing yield that further raising is singly cut is the quick method effectively reducing production cost.
Utility model content
For solving the above-mentioned technical problem existed in prior art, the utility model provides a kind of slicer improvement guide wheel of structural design advantages of simple.The purpose of this utility model is achieved through the following technical solutions:
A kind of slicer improvement guide wheel, comprise steel core and flange, described steel core is cylinder, described flange is arranged on described steel core two ends, between described steel core and described flange, axially steel core extension is set, described steel core extension diameter of section is identical with described steel core section diameter, described steel core and described steel core extension outer wall arranges coat, is provided with wire casing on the coating layer.
Further, the coat on described steel core outer wall and described steel core extension outer application layer are formed in one.
Further, described steel core prolongation is two ends, is separately positioned between described steel core two ends and flange, and the length of every section of steel core extension is 40mm.
Further, described coat axial overall length is 960mm.
Further, described wire casing is multiple independent annulus perpendicular to steel core axis, is set up in parallel on the coating layer.
Further, the width of described wire casing successively decreases successively.
Further, in coat outer end, two ends, 3-5mm region is respectively set and or not wire casing.
Further, on described flange, be provided with locating hole and flange inclined-plane.
The beneficial effects of the utility model are:
A kind of slicer improvement guide wheel disclosed in the utility model, by setting up steel core extension, substantially prolongs guide wheel face length, face length increases to 960mm from original 880mm, wherein effectively face length reaches 950mm, and hilted broadsword section can increase by 380, reaches 2680, production capacity increases by 16.5%, ensures the quality of silicon chip cutting simultaneously; The hilted broadsword section time did not increase compared with originally, improve the utilization rate of steel wire and particle loaded fluid; Separate unit slicer monthly can increase production capacity about 30,000, greatly reduces monolithic production cost.
Accompanying drawing explanation
The cross-sectional view of Fig. 1 a kind of slicer improvement guide wheel disclosed in the utility model;
Fig. 2 is a kind of slicer improvement guide wheel left view disclosed in the utility model;
The A place structure amplification profile structural representation of Fig. 3 a kind of slicer improvement guide wheel disclosed in the utility model;
The B place structure amplification profile structural representation of Fig. 4 a kind of slicer improvement guide wheel disclosed in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail.
A kind of slicer improvement guide wheel, comprise steel core 1 and flange 4, described steel core 1 is elongated cylinder, described flange 4 is arranged on described steel core 1 two ends, between described steel core 1 and described flange 4, axially steel core extension 3 is set, described steel core extension 3 is divided into two ends, is separately positioned between described steel core 1 two ends and flange 4, and the length of every section of steel core extension 3 is 40mm.Described steel core extension 3 diameter of section is identical with described steel core 1 diameter of section, described steel core 1 with described steel core extension 4 outer wall arrange coat 2, coat 2 on described steel core 1 outer wall is formed in one with described steel core extension 3 outer application layer 2, and described coat axial overall length is 960mm.Described coat 2 is provided with wire casing 7, described wire casing 7 is multiple independent annulus perpendicular to steel core 1 axis, be disposed in parallel on described coat 2, it is that 3 ~ 5mm does not arrange wire casing (as shown in Figure 3-4) that guide wheel both ends need reserve long L, object be in order to ensure steel wire work on guide wheel run time, can not guide wheel be jumped out; The depth H of described wire casing is between 0.20mm to 0.22mm, and width W is 0.348mm to 340mm, and be from initiating terminal to ending end be successively decrease step by step.When the object of such control flume width is to ensure section, ensure the consistency of thickness of silicon chip.Because when normal cutting silicon wafer, the steel wire diameter of end of incoming cables is relatively thick, until through carrying out after cutting weares and teares with silicon material, steel wire can be more and more thinner, gap after the cutting of guide wheel latter half steel wire is more and more less, if the wire casing width of afterbody does not reduce, so cut silicon chip will be thickening, and the quality of silicon chip is just unstable.
As shown in Figure 2, on described flange 4, be provided with locating hole 5 and flange inclined-plane 6.Arranging of locating hole 5 ensures that guide wheel correctly, is simultaneously fixed its position position after being installed on slicer equipment; Flange inclined-plane 6 is to load and unload the convenient and reserved specially breach of guide wheel.
Last it is noted that the foregoing is only explanation embodiment of the present utility model; be not limited to the utility model; for a person skilled in the art; all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
