The specific embodiment
Fig. 3 and Fig. 4 represent to utilize method for cutting workpiece involved in the present invention, cut off a plurality of, the mode during 4 workpiece 4 for example simultaneously.In this Fig. 3 and Fig. 4, as an example of wire saw 1, the wire rod 3 of multiple coiling is advanced between two parallel home rolls 2, by 4 workpiece 4 are connected on the wire rod 3 of travel condition, thereby workpiece 4 is cut into the thickness t of target.
The never illustrated carrying device of wire rod 3 is drawn out, via the guide reel 23 that has groove, between a plurality of home rolls 2, groove 2a along each home roll 2 reels multiplely, on the position relative, form after the parallel cut-out zone with workpiece 4, via the guide reel 24 that has groove, send to not shown coiler device.
Each groove 2a of home roll 2 shown in the amplification profile in the circle of Fig. 4, is the endless groove of V font, and at the outer peripheral face of home roll 2, P forms accordingly with the wire rod spacing, and is independently of one another.All wire rods 3, in the cut-out zone relative with workpiece 4, i.e. upper-side area in illustrated embodiment, be housed among the corresponding groove 2a of 2 home rolls 2 and become parallel state, thereby with the center line quadrature of home roll 2, and in not relative non-cut-out zone with workpiece 4, i.e. underside area in the illustrated embodiment, since from the groove 2a of an adjacent side to the groove 2a of opposite side displacement, so advance with respect to the center line of home roll 2 is oblique.Complicated for fear of the line of Fig. 4 divided the oblique travel section of this wire rod 3 partly and to omit.
And, method for cutting workpiece of the present invention is characterised in that, as shown in Figure 3, before cutting off workpiece 4,, utilize and the parallel line of cut-out line C at each workpiece 4, set cutting workpiece zone A, and utilize and the parallel line of cut-out line C,, set wire rod and skip area B between 4 workpiece 4 and end of the configuration direction of workpiece 4.As cutting workpiece zone A, be set in the following scope at each workpiece 4, promptly, on the direction of the target thickness t of workpiece 4, promptly on the configuration direction of 4 workpiece 4, at the both ends of workpiece 4 residual workpiece 4 with respect to the constraint portions of support 5, be the adhesive layer 6 of workpiece 4, simultaneously with respect to support 5, for workpiece 4, can guarantee as certified products necessary sized, promptly cut off height H.In the A of this cutting workpiece zone, workpiece spacing P is set at and the corresponding value of the thickness t of target.
In addition, skip area B as workpiece, be set in the following zone except the A of cutting workpiece zone, promptly, the outside at the cutting workpiece zone A between 2 adjacent workpiece 4 and on the workpiece 4 of the end position of configuration direction, include the adhesive layer 6 residual, and, can guarantee cut-out height H as necessity of certified products for workpiece 4 at the both ends of described workpiece 4.Skip area B in order to set this wire rod, use as wire rod skip with roller for example 1 have a groove skip roller 71.Skip 3 wire rods that roller 71 is configured in except the wire rod at both ends is skipped area B and skip in the area B, and be configured in the outside of home roll 2, the axis of skipping roller 71 is set on the direction that the center line with respect to home roll 2 tilts.Skip in the area B at the wire rod at both ends,, skip area B and set wire rod by wound skein product 3 on home roll 2 not.
In illustrated embodiment, wire rod 3 is drawn out from the cutting workpiece zone A of a side, leaves from home roll 2, is wound on and skips on the roller 71, enters into the cutting workpiece zone A of opposite side then, is wound on the home roll 2, therefore just as open band (open belt).Thus, as shown in Figure 3, the diameter of skipping roller 71 is preferably following size, promptly, be equivalent to the position (position in the outside) of the wire rod 3 that will come out from the cutting workpiece of side zone A and enter cornerwise length that the position (inboard position) of wire rod 3 of the cutting workpiece zone A of opposite side links to each other, but in permissible range, also can use the undersized diameter of comparing with cornerwise length.Thus,, skip on the roller 71,, form bigger interval, skip area B at wire rod and do not have wire rod 3 so skip a plurality of groove 2a that skip home roll 2 in the area B at wire rod owing to skipping to be wound in the area B at wire rod as wire rod 3.
When cutting off workpiece 4, wire saw 1 is advanced by the wire rod 3 that makes multiple coiling between home roll 2, and 4 workpiece 4 are pushed simultaneously on the wire rod 3 of travel condition, thereby in the scope of cutting workpiece zone A, the workpiece 4 of correspondence is cut into the thickness t of target.Otch is regularly finished in cut-out, shown in the illustration of the workpiece 4 of the left-hand end of Fig. 3, is represented by parallel a plurality of cut-out line C.
In the A of cutting workpiece zone, the workpiece 4 that cuts into target thickness t forms multi-disc certified products 4a.Because each certified products 4a after cut-out is finished, is also fixed and is constrained on the support 5 by adhesive layer 6, so can not separate from support.Therefore, multi-disc certified products 4a becomes the state that is removed as product with support 5.
On the other hand, skip in the area B at wire rod, the workpiece 4 that is cut to target thickness t becomes end material 4b.End material 4b produces at the both ends of each workpiece 4, but with certified products 4a similarly, do not lose adhesive layer 6, still keep constraining in state on the support 5 by adhesive layer 6, can not separate from support 5, can not be scattered yet.
Thus, end material 4b can not interfere with wire rod 3, or enters into the groove 2a of home roll 2, perhaps interferes with rotary part, can not cause the bad of the broken string of wire jumper, wire rod of wire rod and rotating part.And after cut-out was finished, the parts 4b at two ends can reclaim with support 5 together with certified products 4a.
In wire rod is skipped the scope of area B, in the position that does not have workpiece 4, for example on the position at the clearance space of 2 workpiece 4, even there is wire rod 3, when cutting workpiece, the wire rod 3 of this position can not interfered with workpiece 4 yet, certainly can not cut off workpiece 4, so the problem that in this scope, does not exist end material 4b to be scattered yet.Thus, in wire rod was skipped the scope of area B, wire rod 3 was not in fact as long as exist in the scope of interfering with workpiece 4.In addition, shown in the example of Fig. 3, be deformed under the situation of rhombus at workpiece 4, if do not satisfy and cut off height H cutting off rear end material 4b, then should end material 4b can with the end material 4b of Fig. 1 left end similarly, become the end material that is scattered.Therefore, according to the example of Fig. 3, end material 4b also must keep cutting off height H.
Fig. 5 illustrates following example, promptly, skip roller 71 for 1 that replaces among Fig. 3 and Fig. 4, and will skip roller 72,73 as less 2 that wire rod is skipped with roller, on the position of the wire rod 3 of the position of the wire rod 3 outside being configured in obliquely and inboard, and wire rod 3 is wound on these obliquely skips on the roller 72,73, there is not wire rod 3 in the area B thereby skip at wire rod.Shown in this example, 2 diameters of skipping roller 72,73 can be very little.
Fig. 6 illustrates following example, promptly, on the position in the outside of wire rod 3 and inboard position, dispose less 2 and skip roller 72,73, make their axis be parallel to the center line of home roll 2, and, the axis of guide reel 81,82 and the center line of home roll 2 are intersected skipping 2 guide reels 81,82 of configuration between the roller 72,73, skip roller 72, guide reel 81,82 and inboard skipping on the roller 73 with what wire rod 3 was wound on the outside successively, thereby in wire rod is skipped area B, do not have wire rod 3.Shown in the example of this Fig. 6, skipping roller 72,73 for 2 can be very little.And the variation of skipping the axis direction of roller 72,73 and the width dimensions that wire rod is skipped area B is irrelevant, always is parallel to the center line of home roll 2, even when wire rod is skipped the change in size of area B, this axis direction does not need change yet.
In addition, Fig. 7 and Fig. 8 illustrate following example, promptly, skip roller 71 with 2 and be configured in the outside of comparing with the non-wire rod 3 that cuts off the zone, be configured in the below in this embodiment, skip between the roller 71, make 1 wire rod 3 cut off the wire rod that regional A jumps to opposite side and cut off regional A from the wire rod of a side at 2.Its result, wire rod 3 wire rod skip area B below, from a side skip roller 71 to opposite side skip roller 71 oblique advancing, from the home roll 2 of a side to the home roll 2 of opposite side reel during, skip wire rod and skip area B.In addition, according to the example of Fig. 3 to Fig. 6, wire rod 3 to the inside the process of position transfer, is being skipped wire rod and is being skipped area B from the position in the outside of wire rod 3 with respect to each home roll 2.In addition, shown in double dot dash line, be positioned at the outside of comparing with the non-wire rod 3 that cuts off the zone, just can as illustrated in imaginary line, suitably set the position of skipping roller 71 as long as be wound on 2 wire rods of skipping on the roller 71 3.Certainly, also can there be dummy roll skipping between the roller 71.
Below, Fig. 9 to Figure 12 represents in order to implement above-mentioned wire rod cutting-off method in practice, with the example of Fig. 6 as basic structure, and in this structure, promptly adopt on 2 bases of skipping roller 72,73 that have a groove, add 3 guide reels 81,82,83 that have groove, thereby constitute the object lesson of device for changing rolling width of wire cutting workpiece 10 of the present invention.In addition, in Fig. 9 and Figure 10, owing to a part of parts and the partially overlapping of front side of the rear side of each figure becomes complicated, so omit.
Among Fig. 9 and Figure 10, the guide reel that has groove 81 of skipping roller 72 and upside of upside utilizes the support of bearing 13 to keep respectively on shaft portion with rotating freely, is installed on the carriage 92 of a side.In addition, the guide reel that has groove 83 of skipping roller 73 and downside of downside utilizes the support of bearing 13 to keep respectively on shaft portion with rotating freely, is installed on the carriage 92 of opposite side.

As shown in figure 12,2 carriages 91,92 utilize the anticreep sliding nut 22 of the inside of the set bolt 21 of each carriage 91,92 side and track 12, in bottom separately, with respect to the track 12 of the section C shape parallel with home roll 2, fixingly go up in position.By adjusting the position of 2 carriages 91,92, can freely set wire rod and skip area B.
As shown in Figure 9, the never illustrated reel of sending side of wire rod 3 is drawn out, at entrance side via the guide reel 23 that has groove, be wound on the groove of home roll 2, corresponding with 4 workpiece 4 and form cutting workpiece zone A, between workpiece 4 and arrange the end and formed after wire rod skips area B, via the guide reel 24 that has groove, be wound on the reel of not shown winding side at outlet side.Because the wire rod between the workpiece 4 is skipped area B and is had 3 places, so the paired roller 72,73 of skipping is arranged on 3 positions.
In addition, the guide reel 23,24 that has groove also can remain on the support 29,30 of guiding usefulness with rotating freely, with carriage 91,92 similarly, utilize the anticreep sliding nut 22 of set bolt 21 and track 12 inside, go up in position with respect to the track 12 of section C shape is fixing.
As shown in figure 11, skip on the boundary position of area B at cutting workpiece zone A and wire rod, wire rod 3 just as set up halved belt (cross belt), home roll 2 and up and down skip the state coiling to intersect between the roller 72,73.The coiling of this crossing condition is in order to increase the winding angle of wire rod 3 with respect to home roll 2, to eliminate wire rod 3 and adopt in the unsettled action of the groove 2a inside of home roll 2.In addition, be provided with receiving magazine 31 below the cut-out zone of wire rod 3, it is used for corresponding with workpiece 4 and host side material 4b etc.
In the example of Fig. 9 to Figure 12, the cut-out of workpiece 4 action is also carried out in the same manner with the method for Fig. 3 and Fig. 4.Shown in the example of Fig. 9 to Figure 12, because the roller 72,73 of skipping up and down utilizes different carriage 91,92 to support independently, so variation of skipping the scope of area B with respect to cutting workpiece zone A and wire rod, in other words, with respect to the variation of the configuration space of the variation of the size of workpiece 4, workpiece 4, can be corresponding flexibly.
Below, Figure 13 shows and utilizes same carriage 93 can keep skipping roller 72,73 with rotating freely, and this carriage 93 is installed in example on the track 12 parallel with home roll 2 with can move freely.
Shown in the example of Figure 13, size at cutting workpiece zone A changes, but when wire rod is skipped area B and changed hardly, move with respect to track 12, can skip under the situation that area B do not change at wire rod and set simply by making carriage 93.
In addition, Figure 14 is that 2 with Fig. 5 skip roller 72,73 corresponding examples, is to utilize the inclination support of bearing 25 and fulcrum shaft 26, will skip roller 72,73 and be installed on the same carriage 93, and can freely adjust the object lesson at angle of inclination.By the bolt 28 of carriage 93 sides is fastening with respect to the circular-arc hole 27 of the inclination support of bearing 25, thereby with the fixed-site of the adjusted inclination support of bearing 25.
In the example of Figure 14, skip roller 72,73 for 2 and also can replace with Fig. 3 and 1 shown in Figure 4 and skip roller 71.
Shown in the example of Figure 14, owing to skip the change in size of area B with respect to cutting workpiece zone A and wire rod, can tackle both change in size simultaneously by adjusting the angle of inclination of the inclination support of bearing 25, so the variation of corresponding these sizes flexibly.
In above example, for workpiece 4 is cut into certified products 4a, only consideration is cut off height H and is determined to cut off regional A.But, as cutting off regional A, when cubical workpiece 4 is cut to certified products 4a, have or not concaveconvex shape according to the shape or the side of workpiece, except cutting off height H, shearing length L or cut off the width W size that also necessitates sometimes.
Figure 15 represents the workpiece 4 of other shape.In Figure 15, the flat shape of workpiece 4 forms trapezoidal, and the leg-of-mutton upper surface in the end is compared downward-slopingly with other upper surface, form the inclined plane of mitigation.Thus, the inclined plane at both ends can be separated from adhesive layer 5, becomes end material 4b and be scattered when cutting off.
Thus, in the example of Figure 15, except the size of the cut-out height H of necessity, also consider effective shearing length L and determine to cut off regional A.And because same reason, for the certified products 4a that obtains stipulating, cutting off width W also can become the size that should consider sometimes when regional A is cut off in decision.Thus, when set cutting off regional A, and have or not concaveconvex shape corresponding, the necessary sized of workpiece 4 as the shape of the silicon ingot of workpiece 4, quality, the particularly side of product, can be to cut off height H, shearing length L or cut off width W, perhaps their combination.In the reality,, in fact cut off regional A and can be set at significant value mostly as long as only guarantee to cut off height H or only guarantee shearing length L or only guarantee to cut off width W.
In addition, home roll 2 is not limited to 2, also can be more, and for example be 3 or 4.Figure 16 is the locational example that 3 home rolls 2 is configured in abreast leg-of-mutton each drift angle, Figure 17 is configured in 4 home rolls 2 on the position of tetragonal each drift angle abreast in addition, the position up and down of wire rod 3 is regional as cutting off, workpiece 4 is configured to 2 sections example up and down.In these examples, receiving magazine 31 be arranged on each workpiece 4 below.
Industrial applicibility
Above concrete example, the mode of a plurality of workpiece 4 of ordered state is cut off in expression simultaneously, cuts off at the same time in the mode of a plurality of workpiece 4 action effect and cut off efficient remarkable. But, purpose of the present invention, i.e. being scattered of anti-not-go-end material 4b, even when cutting off 1 workpiece 4, also set up, so the present invention is not limited to the mode of cutting off simultaneously a plurality of workpiece 4, also comprise cut off 1 workpiece 4 mode interior.
