Otch
As shown in figures 1 and 3, to cut apart the mode of conductive sheet 11 and adhesive layer 13 abreast respectively, in conductive sheet 11, adhesive layer 13 and release sheet material 12 overlapping areas Z, form otch 14 with length direction.That is, in regional Z, equal length with the thickness addition of the thickness of conductive sheet 11 and adhesive layer 13 with the degree of depth (above-below direction among Fig. 1) of the otch 14 that forms with the parallel mode of the length direction of sheet material 10 with discharge.According to this structure, conductive sheet 11 is divided into conductive sheet 11a and electrical sheet material 11b, and adhesive layer 13 is divided into adhesive layer 13a and adhesive layer 13b.On the other hand, the release sheet material 12 of otch 14 no shows, thereby release sheet material 12 is not cut apart by otch 14.Can use formation otch 14 such as cutter.
Sheet material is used in discharge
The discharge of Fig. 1～shown in Figure 3 with sheet material 10 in, as stated,, utilize adhesive layer 13 that release sheet material 12 is bonded on the conductive sheet 11 with its length direction mode parallel with the length direction of conductive sheet 11.In addition, release sheet material 12 is configured in the pars intermedia (with reference to Fig. 1) on the Width of conductive sheet 11.
At this; Pars intermedia is meant like the lower part: in conductive sheet 11, and can be so that the part that parallel with length direction relative two ends of release sheet material 12 and the mode with not aliging in parallel two the relative ends of length direction of conductive sheet 11 dispose.That is, as shown in Figure 2, when on conductive sheet 11, having disposed release sheet material 12, constitute the strip pattern that forms by at least three parts (part of the part of conductive sheet 11a, release sheet material 12 and conductive sheet 11b) and get final product.
In addition, as stated, the mode that otch 14 is cut apart conductive sheet 11 and adhesive layer 13 with the edge direction parallel with length direction forms.The formation position of otch 14 is as long as in conductive sheet 11, adhesive layer 13 and release sheet material 12 overlapping areas Z.
Particularly; Make preferably that X1 and X2 among Fig. 1 equates, Y1 equates with Y2; Promptly the mode with the five equilibrium axis W (with reference to Fig. 2) of the length direction of release sheet material 12 and the five equilibrium axial alignment of the length direction of conductive sheet 11 disposes two sheet materials, and otch 14 aligns with five equilibrium axis W.In this case, can obtain having same widths with sheet material 10 and be equal to big or small adhesive layer 13a, the conductive sheet 11a of 13b, 11b from discharge.In addition, in this manual, the five equilibrium axis is meant parallel with length direction and with the binary axis of Width, for example five equilibrium axis W halves release sheet material 12 broad wayss.
Discharge is with the shape variation of sheet material
Next, use Fig. 4 and Fig. 5 that the shape variation of discharge with sheet material 10 is described.Fig. 4 is the stereogram of the discharge of Fig. 1 with sheet material, and Fig. 5 is the stereogram of the discharge of Fig. 1 when being changed shape with sheet material.
In Fig. 4, release sheet material 12 is configured in the pars intermedia of the Width of conductive sheet 11, and the length direction of this release sheet material 12 is parallel with the length direction of conductive sheet 11.In addition, the five equilibrium axis of the five equilibrium axis of release sheet material 12, conductive sheet and otch 14 alignment.In Fig. 4, if in figure direction of arrow pull-up conductive sheet 11b be positioned at arrow part nearby, the release sheet material 12 that then is adhered to adhesive layer 13b is pulled upwardly with adhesive layer 13b, autoadhesion layer 13a peels off.Particularly, when the bonding force of 13 pairs of conductive sheets 11 of adhesive layer during greater than the bonding force of 13 pairs of release sheet materials 12 of adhesive layer, peeling off of release sheet material 12 autoadhesion layer 13a becomes easy.
After pull-up, as shown in Figure 5, discharge uses sheet material 10 to be following shape: only have conductive sheet 11b to be pulled upwardly among the conductive sheet 11a that is separated, the 11b, release sheet material 12 is peeled off with the state autoadhesion layer 13a that still is adhered to adhesive layer 13b.Under the state of Fig. 5, the further pull-up conductive sheet 11b in top in figure, thus can separate release sheet material 12 fully by autoadhesion layer 13a.Thus, can access the length direction of adhesive layer 13a and end face adhesive layer 13a parallel and use sheet material with the discharge that the end face of conductive sheet 11a aligns with the length direction of conductive sheet 11a.
On the other hand, be bonded in the conductive sheet 11b on the adhesive layer 13b,, make release sheet material 12 outstanding and expose from conductivity sheet material 11b through peeling off conductive sheet 11a for release sheet material 12.Thereby, through the exposed portions serve of clamping and this release sheet material 12 of pull-up, can easily separate conductive sheet 11b and release sheet material 12.The conductive sheet 11a with adhesive layer 13a of being stripped from release sheet material 12 is the target location that pastes on the device that becomes object with the conductive sheet 11b with adhesive layer 13b, brings into play function with sheet material as discharge respectively thus.
With sheet material 10, easily autoadhesion layer 13 separates release sheet material 12 according to the discharge of above this execution mode that details, and therefore discharge becomes easy with the operation of sheet material 10.In addition, through peeling off a release sheet material 12, compare with sheet material with discharge in the past, sheet material is used in the discharge that can access 2 times of amounts.In addition, according to the discharge of this execution mode structure with sheet material 10, adhesive layer 13a, 13b respectively can be outstanding from conductivity sheet material 11a, 11b.And, in the past need the narrower thin discharge of width with the management of sheet material, the aspect such as pack and add to note, but according to this execution mode, owing to can have in the past discharge, so its management, pack and become easy with 2 times width of sheet material.In addition, quantity control is also easy.
(second execution mode)
As second execution mode, use Fig. 6 and Fig. 7 that the example of discharge of the present invention with the manufacturing approach of sheet material is described.Fig. 6 is the flow chart of the discharge of expression second execution mode with an example of the manufacturing approach of sheet material, and Fig. 7 is the sketch map that is used for the manufacturing approach of key diagram 6.In this execution mode, following situation is described: use among Fig. 7 schematically illustrated structure to implement manufacturing approach shown in Figure 6, thereby the discharge of shop drawings 1～shown in Figure 3 is with the situation of sheet material 10.
At first, like Fig. 6 and shown in Figure 7, prepare to be wound with the 1st scroll A and the 2nd scroll B (step S1) that is wound with the release sheet material 22 of the band shape that on a surface, is formed with adhesive layer 23 of banded conductive sheet 21.In addition, here conductive sheet 21, release sheet material 22 and adhesive layer 23 is illustrated in the first embodiment conductive sheet 11, release sheet material 12 and continuous along its length respectively materials of adhesive layer 13.
For example; Can make the 1st scroll A as follows: will have the several times of the target width of conductive sheet 11, for example 20 times the conductive sheet of width is center and reeling along its length with the core, with broad wayss such as cutters this conductive sheet is divided into 20 five equilibriums then.Because the production efficiency of the 1st scroll A is higher, so this method is suitable for making a large amount of discharges with sheet material 10.
In addition, also can adopt the method identical, make the 2nd scroll B with higher production efficiency with the manufacture method of above-mentioned the 1st scroll A.The release sheet material of supplying with from the 2nd scroll B 22 with the conductive sheet facing surfaces, be that the upper surface side of the release sheet material 22 among Fig. 7 is formed with adhesive layer 23.In addition, the width of release sheet material 22 is than the narrow width of conductive sheet 11.
Next; Like Fig. 6 and shown in Figure 7; Supply with on one side conductive sheet 21 and release sheet material 22 along its length continuously, on one side with the state that between a surface of surface of conductive sheet 21 and release sheet material 22, disposes adhesive layer 23 be bonded to each other (step S2).This operation for example can be carried out as follows.
That is, at first, utilize donor rollers 24,25 along its length (direction of arrow among the figure) supply with conductive sheet 21 continuously.On the other hand, utilize donor rollers 26,27 to supply with release sheet material 22 along its length continuously.Conductive sheet 21 and the release sheet material 22 supplied with continuously pass between 1 couple of crimping roller 28a, the 28b, thus crimping each other.As stated owing in the figure of release sheet material 22, be formed with adhesive layer 23 on the upper surface, therefore after the pressurization of being undertaken by crimping roller 28a, 28b is bonding, produce stack gradually conductive sheet 21, adhesive layer 23 and release sheet material 22 discharge with material 20.In addition, in Fig. 7, each roller is towards the circular-arc direction of arrow rotation of mark respectively.
In this step S2, so that the length direction of release sheet material 22 mode parallel with the length direction of conductive sheet 21 supplied with release sheet material 22.In addition, utilize adjusting mechanism to adjust the position of release sheet material 22, dispose release sheet material 22 with pars intermedia at the Width of conductive sheet 21.In this execution mode so that with the binary five equilibrium axis of the Width of release sheet material 22 with the mode of the binary five equilibrium axial alignment of the Width of conductive sheet 21 is adjusted.
Next, like Fig. 6 and shown in Figure 7, Yi Bian carry discharge along its length continuously with material 20, Yi Bian in conductive sheet 21, adhesive layer 23 and release sheet material 22 overlapping areas, cut out otch (step S3).This operation for example can be carried out as follows.
That is the deflector roll 29 guiding discharges that, utilize direction of arrow rotation in figure are with material 20, so that this discharge is passed between 1 couple of otch roller 30a, 30b with material 20.On otch roller 30a, discoideus cutter are installed, can cut out otch on material 20 passing discharge between otch roller 30a, the 30b.Can regulate the distance between otch roller 30a and the otch roller 30b, can regulate thus passing discharge between this otch roller 30a, the 30b with the notch depth of material 20.In this execution mode; So that otch with the mode of the binary five equilibrium axial alignment of the Width of release sheet material 22; And so that the mode of the equal in length behind the thickness of the thickness of the degree of depth of otch and addition conductive sheet 21 and adhesive layer 23 is regulated.Thereby, through carrying out step S3, utilize otch and its length direction will discharge abreast and halve with the conductive sheet 21 of material 20 and the Width of adhesive layer 23.
Next, like Fig. 6 and shown in Figure 7, Yi Bian (direction of arrow among the figure) carries the discharge that is formed with otch with material 20 continuously along its length, Yi Bian be somebody's turn to do discharge with material 20 with predetermined length cutting along its length, thus discharge formed with sheet material 10 (step S4).This operation for example can be carried out as follows.
That is, utilize otch roller 30a, 30b to carry the discharge that is formed with otch along its length, this discharge is passed between 1 couple of deflector roll 31a, 31b with material 20 with material 20. Deflector roll 31a, 31b have following function: the rotating speed through measuring deflector roll 31a, 31b, the anglec of rotation etc., measure the discharge of between roller, passing length with material 20.So,, can discharge be cut into target length with material 20 through control the translational speed of the above-below direction of cutter 32 according to its length that measures.In addition, the point of a knife of cutter 32 is configured to parallel with the Width that discharges with material 20, utilizes the moving of above-below direction of cutter 32, can easily cut the discharge that is configured between base 33 and the cutter 32 with material 20.
Utilize above operation (step S1～S4) continuously the discharge of shop drawings 1～shown in Figure 3 with sheet material 10.
According to the manufacturing approach of above this execution mode that details, can be easily and make discharge continuously with sheet material 10.The operation of in addition, need not the end face that makes release sheet material as in the past aliging with the end face of conductive sheet.In addition, after bonding to conductive sheet 21 on by adhesive layer 23 release sheet material 22, cutting conductive sheet 21 and adhesive layer 23, so adhesive layer 23 can not given prominence to and expose from conductivity sheet material 21.Thereby, according to the manufacturing approach of this execution mode, can make discharge efficiently with sheet material 10 with good rate of finished products.
Particularly, when conductive sheet 21 was nonwoven fabrics, uneven thickness in this case, was difficult to make the end face of release sheet material and the end face complete matching of conductive sheet sometimes sometimes.Promptly; When carrying conductive sheet 21 continuously along its length; Length direction along conductive sheet 21 is applied with tensile force, and the elongation of the conductive sheet 21 of uneven thickness can be inconstant, therefore is difficult to make the end of conductive sheet 21 and the end part aligning of release sheet material 22 sometimes.To this, according to the manufacturing approach of this execution mode, even the uneven thickness of conductive sheet 21, adhesive layer 23 can be not outstanding from conductivity sheet material 21 yet.In addition, elongation is meant the elongation easness of member.
In addition, as stated,,, then need make 1 discharge with the scroll sheet material thickness, that be wound with conductive sheet and release sheet material if adopt manufacturing approach in the past using the 1st scroll A and the 2nd scroll B to make under the situation of discharge with sheet material.That is, when the manufacturing approach that adopts in the past, making under the thinner situation of discharge with sheet material of discharge, needing to make the 1st scroll A of 5mm width and the 2nd scroll B narrower than 5mm with sheet material, for example 5mm.Be difficult to make the scroll of this narrow width, can't make width impartial the 1st scroll A and the 2nd scroll B sometimes with the manufacture method of above-mentioned that kind.To this, according to this execution mode, make 2 discharges and get final product with the 1st scroll A and the 2nd scroll B of sheet material thickness, under above-mentioned situation, make the 1st scroll A of 10mm width and the 2nd scroll B narrower and get final product than 10mm.Thereby through using this 1st scroll A and the 2nd scroll B, sheet material is used in the discharge that can be manufactured on size equalization on the Width with good rate of finished products.
In addition, according to this execution mode, conductive sheet 21 and adhesive layer 23 divided discharges cut into the length of target with material 20 Yi Bian utilize cutter 32 to discharge with material 20 Yi Bian carry release sheet material 22 not cut apart along its length continuously.At this, when utilizing otch that release sheet material 22 has also been cut apart, 2 discharges are transported to cutter 32 places with material.In this case, 2 discharges are not parallel conveyings with material sometimes, and carry slightly on the bias.To this, use Fig. 8 to describe.
Fig. 8 is the vertical view that 2 conductive sheets are in the shape of the letter V and arrange.Utilize otch roller 30a be divided into 2 each discharge with material 81a, 81b be transported to cutter 32 during, that kind as shown in Figure 8 is in the shape of the letter V unlimited.In addition, each discharge with material 81a, 81b is last is bonded with each release sheet material 82a, 82b by adhesive layer.The discharge that has arrived cutter 32 places is not vertically to send into respect to the point of a knife of cutter 32 with material, therefore for example according to the cutting of the position shown in dashed lines among the figure.In this case, discharge is with the length direction and the Width out of plumb of sheet material, and the length of 2 end faces of length direction is inconsistent.This can cause decrease in yield.
Particularly; Under the situation about constitute by fiber at conductive sheet 21, elongation differing widely between conductive sheet 21 and the release sheet material 22; For example under the paper after release sheet material 22 is handled by silicon, the situation that polyester constitutes; Each discharge differs widely with the elongation at the both ends of the length direction of material 81a, 81b, therefore occurs the phenomenon of 2 conductive material deflections easily.In addition, under length the situation than weak point of discharge with sheet material, this deflection has influence on total easily.Thereby; Under the situation that the elongation between conductive sheet and the release sheet material differs widely, the discharge that will make with the short situation of the length of sheet material under; Particularly under the situation below the 30mm, especially preferably as this execution mode, do not cut the formation discharge of release sheet material 22 ground and use sheet material.
In other words, under length the situation than length of discharge, also can utilize otch that release sheet material 22 is cut apart with conductive sheet 21 and adhesive layer 23 with sheet material.Particularly, fully long in discharge with the length of sheet material, more than the for example 1000mm, discharge with the width of sheet material also more greatly, under the situation more than the for example 80mm, above-mentioned deflection can be to the bigger influence of total generation.Thereby, length that sheet material is used in discharge as the situation more than the 1000mm under, except the manufacturing approach of above-mentioned execution mode, also can adopt the method that release sheet material 22 is cut to discharge and use sheet material with good rate of finished products manufacturing.But in this case, the discharge that make is identical with sheet material with discharge shown in Figure 9 with the structure of sheet material.
