At this, near band compression joint mechanism 33, like Fig. 1 and shown in Figure 3, be provided with: band shoutoff mechanism 36 forms otch 51c on ACF is attached to the end positions of the part on the bonding object parts 52 in 51 ACF parts 51a; Band exhaustion mechanism 37, the ACF that order is transported by band conveyer structure 15 pulls out the length that should attach to the needs on the bonding object parts 52 with 51 and is positioned on the bonding object parts 52.In addition, as shown in Figure 3, only ACF parts 51a is carried out with 51 cut-out based on the ACF that is with shoutoff mechanism 36, cover tape 51b is not carried out.
In addition, near band compression joint mechanism 33, like Fig. 1 and shown in Figure 3, band detent mechanism 39,39 is set, the ACF that will be transported to band compression joint mechanism 33 by band conveyer structure 15 carries out this ACF with 51 location with 51 to 52 pushings of bonding object parts.
And then, as shown in Figure 4 near band compression joint mechanism 33, band mechanism for stripping 45 is set, peel off cover tape 51b from the ACF parts 51a that is crimped on the bonding object parts 52 by band compression joint mechanism 33.
If get back to Fig. 1 and then explanation, then machine for automatically recovering structure 40 has: reclaim spool 41, transport this ACF with the ACF after using with 51 the states on the part of its circumferential groove 41a of being wound on and be with 51; Drive the recovery side drive axle 42 that reclaims spool 41 rotations; Recovery is by reclaiming ACF after the use that spool 41 transports with 51 collection box 44.At this; Reclaim in the spool 41; A plurality of vacuum attractions hole is set at coiling ACF on 51 circumferential groove 41a, makes the part that only is positioned at the first half that reclaims spool 41 among the circumferential groove 41a be in the attraction state all the time through the attraction state that switches each vacuum attraction hole with the rotation interlock ground that reclaims spool 41.
Then, the action to the ACF adhering device 10 of such formation describes.
In ACF adhering device 10 shown in Figure 1; ACF is with 51;, transported in the following manner from emitting by feed mechanism 11: be positioned to carry via stationary roll 16,17, adhesive film tape feeding mechanism (the three-dimensional conveyer of supply side) 18, supply side mobile rollers 23 (supply side tension mechanism 31) and stationary roll 24 and put on the bonding object parts 52 on the backing plate 34 of compression joint mechanism 33 by the supply spool 12 of supply side axle drive shaft 13 driven in rotation.
More specifically; By strap clamp tight mechanism (not shown) clamp ACF with 51 state under; If the rotation that makes supply spool 12 be accompanied by supply side axle drive shaft 13 drives and rotates to direction as shown; Then ACF band is emitted from supply spool 12, and this ACF is with 51 to be transported via band conveyer structure 15 (particularly stationary roll 16,17, adhesive film tape feeding mechanism (the three-dimensional conveyer of supply side) 18 and supply side mobile rollers 23), this ACF be with produce on 51 lax.At this; In supply side tension mechanism 31; Under control based on control setup 67; Drive by CD-ROM drive motor 66 and 65 pairs of driven rollers 63 of moment of torsion applicator, make the propulsive effort transmission move with 64 the directions of arrow to the solid line of Fig. 2, thus to ACF with 51 apply certain tension force state order to rise by the supply side mobile rollers 23 of supply side mobile rollers guide 31a guiding.In addition; At this moment, the control setup 67 of supply side tension mechanism 31 is with the mode controlling and driving motor 66 of the propulsive effort that reduces supply side mobile rollers 23 is applied, thus; Transport by band conveyer structure 15 ACF with 51 stage in, give lower tension force to ACF with 51.
And, if supply side mobile rollers 23 rises and arrives upper limit position, then stop the rotation driving of supply side axle drive shaft 13 and the driving of CD-ROM drive motor 66.Thus, become following state, that is, emit the ACF that should attach to length required on the bonding object parts 52 from the supply spool 12 of feed mechanism 11 temporarily and be with 51, and be stored between supply spool 12 and the stationary roll 24.
Under this state; Remove ACF with 51 clamping through decontroling the tight mechanism of strap clamp (not shown); And the rotation that stops supply side axle drive shaft 13 drives, if under this state, is with 51 to pull out to direction as shown ACF by band exhaustion mechanism 37; The supply side mobile rollers 23 that is then kept by the supply side mobile rollers guide 31a of supply side tension mechanism 31 begins to descend, and is stored in ACF between supply spool 12 and the stationary roll 24 and is with 51 to move to graphic direction.At this; In supply side tension mechanism 31; Under control based on control setup 67, drive by CD-ROM drive motor 66 and 65 pairs of driven rollers 63 of moment of torsion applicator, make the propulsive effort transmission move with 64 the directions of arrow to the dotted line of Fig. 2; Thus, to ACF with 51 apply certain force of strain state order to descend by the supply side mobile rollers 23 of supply side mobile rollers guide 31a guiding.In addition, at this moment, the control setup 67 of supply side tension mechanism 31 is with the mode controlling and driving motor 66 of the propulsive effort that reduces supply side mobile rollers 23 is applied, transport by band conveyer structure 15 ACF with 51 stage in, ACF is applied lower tension force with 51.Thus, descend and when arriving the lower position, make ACF be positioned on the bonding object parts 52 with the ACF parts that should be attached on the bonding object parts 52 in 51 in supply side mobile rollers 23.
Afterwards, as shown in Figure 3 by near the band detent mechanism 39,39 that is arranged on band compression joint mechanism 33, will be with 15 by the ACF that band conveyer structure 15 is transported to compression joint mechanism 33 places to 52 pushings of bonding object parts, and carry out this ACF with 51 location.At this moment; In supply side tension mechanism 31; Under control based on control setup 67, drive by CD- ROM drive motor 66 and 65 pairs of driven rollers 63 of moment of torsion applicator, make the propulsive effort transmission make the supply side mobile rollers 23 set distance that only rises with the 64 solid arrow directions to Fig. 2 move.Thus, carrying out ACF in the stage with 51 location, can strengthen the propulsive effort that supply side mobile rollers 23 is applied and ACF is given than higher tension force with 51 by band detent mechanism 39,39.
And; In band compression joint mechanism 33; Make ACF adhesion mechanism 35 move to carrying the bonding object parts of putting on backing plate 34 52; Pushing is with 51 by the ACF that band detent mechanism 39,39 is positioned on the bonding object parts 52, thus ACF is crimped on the bonding object parts 52 with a part that becomes the ACF parts (the Reference numeral 51a of Fig. 3) that attach object in 51.In addition, at this moment, be attached in 51 ACF parts 51a on the end positions of the part on the bonding object parts 52 at ACF, by band shoutoff mechanism 36 at set moment incision otch 51c.
Afterwards, as shown in Figure 4 by near the band mechanism for stripping 45 that is arranged on band compression joint mechanism 33, peel off cover tape 51b from the ACF parts 51a that is crimped on the bonding object parts 52 by band compression joint mechanism 33.At this moment; In supply side tension mechanism 31; Under control based on control setup 67, drive by CD- ROM drive motor 66 and 65 pairs of driven rollers 63 of moment of torsion applicator, make the propulsive effort transmission move and make the supply side mobile rollers 23 set distance that only descends with 64 the directions of arrow to the dotted line of Fig. 2.Thus, being undertaken in the stage of peeling off of cover tape 51b, reduce the propulsive effort that supply side mobile rollers 23 is applied and ACF is applied lower tension force with 51 by band mechanism for stripping 45.
And; Finally; ACF after the use of crimping ACF parts 51a and main only residual cover tape 51b is with 51 via stationary roll 25, reclaims side mobile rollers 26 (reclaiming side tension mechanism 32) and adhesive film tape feeding mechanism (reclaiming edge-on body conveyer) 27 and be transported like this; Finally, reclaim by machine for automatically recovering structure 40.
More specifically; By strap clamp tight mechanism (not shown) clamp ACF with 51 state under; If order reclaims that spool 41 is followed the driven in rotation that reclaims side drive axle 24 and to graphic direction rotation, then reclaim spool 41 and transport this ACF with the ACF after using with 51 the states on the part of its circumferential groove 41a of being wound on and be with 51.Promptly; Reclaim spool 41 through switching the attraction state in each vacuum attraction hole with its rotation interlock ground; Make the part that reclaims spool 41 the first half that only is positioned among the circumferential groove 41a be in the attraction state all the time; Reclaiming on the circumferential groove 41a of spool 41, only will upstream side furthered and fixing use after ACF with 51 both measured lengths of transporting less than a week, be pulled away from the set position that is pulled away from downstream afterwards.Thus, under its deadweight effect, transport with 51 at the ACF that is pulled away from after the use that the position is pulled away from of circumferential groove 41a, finally reclaim by collection box 44 with (moving direction of mobile rollers 26) sagging state on above-below direction from reclaiming spool 41.In addition, the ACF that is wound on after the use of reclaiming on the spool 41 is reeled with the circumferential groove 41a state of contact that reclaims spool 41 with the face (cover tape 51b shown in Figure 3 then is its upper surface) that does not attach ACF parts 51a one side among the cover tape 51b that is comprised in 51 with this ACF with 51.
In addition, above-mentioned such reclaim by machine for automatically recovering structure 40 ACF after using with 51 process in, in reclaiming side tension mechanism 32, produce ACF after drawing uses downwards with 51 power.At this; In reclaiming side tension mechanism 32; Under control based on control setup 67; Drive by CD- ROM drive motor 66 and 65 pairs of driven rollers 63 of moment of torsion applicator, make the propulsive effort transmission move with 64 dotted arrow directions to Fig. 2, thus to ACF with 51 apply certain tension force state order to descend by the supply side mobile rollers 26 that reclaims side mobile rollers guide 32a guiding.In addition; At this moment; The control setup 67 that reclaims side tension mechanism 32 to be reducing reclaiming the mode controlling and driving motor 66 of the propulsive effort that side mobile rollers 26 applies, transport through band conveyer structure 15 like this ACF with 51 stage in, give lower tension force to ACF with 51.
And side mobile rollers 26 descends and the arrival lower position if reclaim, and then stops to reclaim the rotation driving of side drive axle 42 and the driving of CD-ROM drive motor 66.
Under this state; Remove ACF with 51 clamping through decontroling the tight mechanism of strap clamp (not shown); And the rotation driving that stops to reclaim side drive axle 42; Under this state, be with 51 if pull out ACF to direction as shown by band exhaustion mechanism 37, then should be with 51 generations lax by the ACF after the use of machine for automatically recovering structure 40 recovery.At this; In reclaiming side tension mechanism 32; Under control based on control setup 67, drive by CD-ROM drive motor 66 and 65 pairs of driven rollers 63 of moment of torsion applicator, make the propulsive effort transmission move with 64 solid arrow directions at Fig. 2; Thus, to ACF with 51 apply certain tension force state order to rise by the supply side mobile rollers 23 that reclaims side mobile rollers guide 32a guiding.In addition; At this moment; The control setup 67 that reclaims side tension mechanism 32 to be reducing reclaiming the mode controlling and driving motor 66 of the propulsive effort that side mobile rollers 26 applies, transport by band conveyer structure 15 like this ACF with 51 stage in, give lower tension force to ACF with 51.And; Be with 51 to pull out if should be attached to the ACF of the required length on the bonding object parts 52 by band exhaustion mechanism 37; Then reclaim 26 risings of side mobile rollers and arrive upper limit position, so should stop to reclaim the rotation driving of side drive axle 42 and the driving of CD-ROM drive motor 66 constantly.

Wherein, the 1st tape feed mechanism 121 has and is positioned at the 1st plane P 1In the bigger big roller 123 of diameter and with respect to the 1st plane P 1The bevelled state is positioned at the smaller pony roll 124 of diameter of going back the downstream than this big roller 123.In addition, the 2nd tape feed mechanism 122 has and is positioned at the 2nd plane P 2In the bigger big roller 126 of diameter and with respect to the 2nd plane P 2The bevelled state is positioned at the smaller pony roll 125 of diameter of going back upstream side than this big roller 126.In addition, the big roller 123 of the 1st tape feed mechanism 121 and pony roll 124 are respectively by the fulcrum 123a, the 124a rotation supporting freely that are fixed on the supporting mass 137.In addition, the big roller 126 of the 2nd tape feed mechanism 122 and pony roll 125 are respectively by the fulcrum 126a, the 125a rotation supporting freely that are fixed on the supporting mass 138.
At this, each big roller 123,126 that contains in the 1st tape feed mechanism 121 and the 2nd tape feed mechanism 122 is as shown in Figure 8, has concave groove 141, this concave groove have with ACF be rectangular-shaped with cooresponding size of 51 width and cross section.In addition, each pony roll 124,125 that contains in the 1st tape feed mechanism 121 and the 2nd tape feed mechanism 122 is as shown in Figure 9, has down dovetail groove 142, and the dovetail groove 142 that should fall has with ACF with the cooresponding size of 51 width and cross section for trapezoidal.
Then, the effect to the adhesive film tape feeding mechanism 18 that is made up of such structure describes.
At first, emit and in the 1st plane P from the supply spool 12 of feed mechanism 11 1In the ACF that is transported be with 51 in the 1st tape feed mechanism 121, to be positioned at the 1st plane P 1After interior big roller 123 transports, transport by near the pony roll the downstream that is arranged on big roller 123 124.At this, pony roll 124 is with respect to the 1st plane P 1The bevelled state arrangement, the ACF that sees off from big roller 123 is passed out to the 2nd band delivering mechanism 122 with 51 being applied with to it under the state that reverses.In addition, be with 51 to separate from big roller 123 and pony roll 124 in order to prevent ACF, from big roller 123 see off ACF with 51 position and to pony roll 124 send into ACF with 51 optimum seeking site on same plane (the 1st plane P 1) interior (with reference to Fig. 6 A).
Then, be with 51 the 2nd tape feed mechanism 122, to be set at and to be positioned at the 2nd plane P from the pony roll 124 of the 1st tape feed mechanism 121 with the ACF that is applied with the state that reverses and is seen off 2Near the upstream side of interior big roller 126 pony roll 124 transports, and afterwards, is transported by big roller 126.In addition, the ACF that is transported by big roller 126 is with 51 to being positioned at the 2nd plane P 2Interior supply side mobile rollers 23 is seen off.At this, pony roll 125 is with respect to the 2nd plane P 2The bevelled state arrangement, the ACF that sees off from the pony roll 124 of the 1st tape feed mechanism 121 is with 51, applies reversing and passed out to big roller 126 above that while recover.In addition, be with 51 to separate from pony roll 125 and big roller 126 in order to prevent ACF, from pony roll 125 see off ACF with 51 position and to big roller 126 send into ACF with 51 optimum seeking site on same plane (the 2nd plane P 2) interior (with reference to Fig. 6 A).
In addition, as above such ACF that is transported by the 1st tape feed mechanism 121 and the 2nd tape feed mechanism 122 is with 51, is positioned at two different plane (the 1st plane P each other because it transports the path 1And the 2nd plane P 2) in, so can transport under with 51 upstream side part and the mutual clover leaf state of downstream part at ACF.
Then, by Fig. 1, Fig. 7 A and Fig. 7 B the detailed structure of the adhesive film tape feeding mechanism (reclaiming edge-on body conveyer) 27 of the recovery side that is arranged on ACF adhering device 10 is described.In addition, Fig. 7 A is the birds-eye view of the detailed structure of expression adhesive film tape feeding mechanism 27 shown in Figure 1, and Fig. 7 B is that the ACF of the adhesive film tape feeding mechanism 27 shown in presentation graphs 1 and Fig. 7 A is with 51 the skeleton diagram that transports the path.In addition; In Fig. 7 A and Fig. 7 B; In adhesive film tape feeding mechanism shown in Figure 1 27, to transport the downstream of using stationary roll 131 and use to transport and use the situation of identical stationary roll of stationary roll 129 rather than recovery spool 41 as shown in Figure 1 to describe reclaiming edge-on body as example with the edge-on body of recovery.
Shown in Fig. 1, Fig. 7 A and Fig. 7 B, adhesive film tape feeding mechanism 27 has: the 1st tape feed mechanism 127, and on one side in the 1st plane P 3In the ACF that transports be with 51 apply reverse on one side to the 1st plane P 3The 2nd different plane P 4Transport this ACF and be with 51; The 2nd tape feed mechanism 128 is with 51 in the 2nd plane P in order to make to be applied with the ACF that the state that reverses is transported by the 1st tape feed mechanism 127 4In transport, make to be applied to this ACF with the post-equalization of reversing on 51, transport this ACF simultaneously and be with 51.
Wherein, the 1st tape feed mechanism 127 has and is positioned at the 1st plane P 3In the bigger big roller 129 of diameter and with respect to the 1st plane P 3The bevelled state is positioned at the smaller pony roll 130 of diameter of going back the downstream than this big roller 129.In addition, the 2nd tape feed mechanism 128 has and is positioned at the 2nd plane P 4In the bigger big roller 132 of diameter and with respect to the 2nd plane P 4The bevelled state is positioned at the smaller pony roll 131 of diameter of going back upstream side than this big roller 132.In addition, the big roller 129 of the 1st tape feed mechanism 127 and pony roll 130 are respectively by the fulcrum 129a, the 130a rotation supporting freely that are fixed on the supporting mass 139.In addition, the big roller 132 of the 2nd tape feed mechanism 128 and pony roll 131 are respectively by the fulcrum 132a, the 131a rotation supporting freely that are fixed on the supporting mass 140.
At this, each big roller 129,132 that contains in the 1st tape feed mechanism 127 and the 2nd tape feed mechanism 128 is as shown in Figure 8, has concave groove 141, this concave groove have with ACF be rectangular-shaped with cooresponding size of 51 width and cross section.In addition, each pony roll 130,131 that contains in the 1st tape feed mechanism 127 and the 2nd tape feed mechanism 128 is as shown in Figure 9, has down dovetail groove 142, and the dovetail groove 142 that should fall has with ACF with the cooresponding size of 51 width and cross section for trapezoidal.
Then, the effect to the adhesive film tape feeding mechanism 27 that is made up of such structure describes.
At first, via reclaiming side mobile rollers 26 in the 1st plane P 3In the ACF that is transported be with 51 in the 1st tape feed mechanism 127, to be positioned at the 1st plane P 3After interior big roller 129 transports, transport by near the pony roll the downstream that is arranged on big roller 129 130.At this, pony roll 130 is with respect to the 1st plane P 3The bevelled state arrangement, the ACF that sees off from big roller 129 is passed out to the 2nd band delivering mechanism 128 with 51 to be applied with the state that reverses to it.In addition, be with 51 to separate from big roller 129 or pony roll 130 in order to prevent ACF, from big roller 129 see off ACF with 51 position and to pony roll 130 send into ACF with 51 optimum seeking site on same plane (the 1st plane P 3) interior (with reference to Fig. 7 A).
Then, be with 51 the 2nd tape feed mechanism 128, to be set at and to be positioned at the 2nd plane P from the pony roll 130 of the 1st tape feed mechanism 127 with the ACF that is applied with the state that reverses and is seen off 4Near the upstream side of interior big roller 132 pony roll 131 transports, and afterwards, is transported by big roller 132.In addition, the ACF that is transported by big roller 132 is with 51 to be positioned at the 2nd plane P to conduct 4The collection box 44 of interior output mechanism is seen off.At this, pony roll 131 is with respect to the 2nd plane P 4The bevelled state arrangement, the ACF that sees off from the pony roll 130 of the 1st tape feed mechanism 127 is with 51, applies reversing and passed out to big roller 132 above that while recover.In addition, be with 51 to separate from pony roll 131 and big roller 132 in order to prevent ACF, from pony roll 131 see off ACF with 51 position and to big roller 132 send into ACF with 51 optimum seeking site on same plane (the 2nd plane P 4) interior (with reference to Fig. 7 A).
In addition, as above such ACF that is transported by the 1st tape feed mechanism 127 and the 2nd tape feed mechanism 128 was with 51 o'clock, because ACF is positioned at two different plane (the 1st plane P each other with 51 the path of transporting 3And the 2nd plane P 4) in, so ACF is with 51 can swim under side sections and the mutual clover leaf state of downstream part and transport above that.
According to this such embodiment; The supply side tension mechanism 31 and the recovery side tension mechanism 32 that transport on the path that are configured in band conveyer structure 15 have the propulsive effort applicator 61 that the supply side mobile rollers 23 (perhaps reclaiming side mobile rollers 26) by supply side mobile rollers guide 31a (perhaps reclaiming side mobile rollers guide 32a) guiding is applied propulsive effort; Under control, adjust the propulsive effort that supply side mobile rollers 23 (or reclaiming side mobile rollers 26) is applied with 51 tension force according to the ACF of needs in each stage of the attaching process of ACF parts 51a based on control setup 67.Therefore; For example based on the ACF of band conveyer structure 15 during with 51 transport; During based on the peeling off of cover tape 51b after the crimping of band mechanism for stripping 45 and based on the ACF of autosplice machine structure 38 during with 51 automatic joint, with give the tension force of ACF with 51 remain lower, on the other hand;, remain than higher during at ACF giving the tension force of ACF with 51 with 51 location.Thus, ACF can be improved, and peeling off and variety of issue that ACF produces with 51 automatic joint etc. of the cover tape 51b of ACF after can be avoided being accompanied by with 51 transport, crimping with 51 accuracy of positioning.Particularly, because low to ACF during with 51 transport, so can carry out ACF at high speed with 51 transport with 51 tension force given based on the ACF of band conveyer structure 15.In addition, because also low to ACF during the peeling off of cover tape 51b after crimping, be acute angle with respect to the peel angle of ACF parts 51a so can reduce cover tape 51b with 51 tension force given, the occurrence frequency of ACF parts 51a turnup.And then, because also low to ACF during with 51 automatic joint,, can reduce the open circuited occurrence frequency of ACF with 51 automatic junction surface so can not apply excessive stress with 51 to ACF with 51 tension force that apply at ACF.And then, owing to be not to be with 51 to give high tension to ACF all the time, so also have to carrying out ACF with the supply spool 12 of 51 supply and recovery and reclaim the advantage that spool 41 does not apply excessive stress.
In addition, according to this embodiment, at the supply side that is arranged on ACF adhering device 10 and reclaim in the adhesive film tape feeding mechanism 18,27 of side, by the 1st tape feed mechanism 121,127, on one side in the 1st plane P 1, P 3In the ACF that transports be with 51 apply reverse on one side to the 1st plane P 1, P 3The 2nd different plane P 2, P 4Transport this ACF and be with 51, afterwards, by the 2nd tape feed mechanism 122,128, to be with 51 in the 2nd plane P being applied with the ACF that is transported under the state that reverses by the 1st tape feed mechanism 121,127 2, P 4In the mode that is transported will be applied to this ACF on one side transporting this ACF will be with 51 on one side with the post-equalization of reversing on 51.Therefore, the ACF that is transported by the 1st tape feed mechanism 121,127 and the 2nd tape feed mechanism 122,128 is positioned at two different plane (the 1st plane P each other with 51 the path of transporting 1, P 3And the 2nd plane P 2, P 4) in, ACF is with 51 can swim under side sections and the mutual clover leaf state of downstream part and transport above that.Therefore; Can set the ACF that transports by ACF adhering device 10 with 51 the path of transporting with high-freedom degree; Change between the supply spool 12 of the feed mechanism 11 of ACF adhering device 10 and supply side mobile rollers 23, autosplice machine structure 38 being set ACF with 51 transport the path time; The recovery side to ACF adhering device 10 be provided with change as the collection box 44 of output mechanism ACF with 51 transport the path time, also can be flexibly to change that should structure.
