Description

Adhesive label and adhesive label roll

Technical field

The present invention relates to a kind of adhesive label who is adhered on the film with the stripping portion of alternately arranging and residual portion, and relate to the adhesive label roll with this adhesive label, described adhesive label engages described stripping portion.

Background technology

The substrate that is used for liquid crystal panel, printed-wiring board (PWB) and PDP covers the photosensitive sheet (photosensitive web) on the substrate surface, the photosensitive material layer (photosensitive resin layer) of having applied ointment or plaster on this photosensitive sheet (photosensitive web).Photosensitive sheet comprises successive layer and is pressed onto photosensitive material layer and diaphragm (coverlay) on the flexiplast carrier.

It is as follows to be used for application device work that photosensitive sheet is applied on the substrate: with substrate such as glass substrate, resin substrates etc. with predetermined compartment every charging.On photosensitive sheet, the diaphragm of the length of will aliging with the respective area of photosensitive material layer is peeled off, and the respective area with photosensitive material layer is applied on the substrate subsequently.

For example, Japanese publication publication 2001-6995 discloses a kind of film technology of applying ointment or plaster.According to the disclosed film technology of applying ointment or plaster, as shown in Figure 15 of accompanying drawing, multilayer film 1 changes it and changes direction that roller 2 is advanced around direction, and direction changes roller 2 and is positioned adjacent to coverlay mechanism for stripping 3.Multilayer film 1 comprises by basilar memebrane 1a, the laminated compenent that resist film 1b and coverlay 1c make.Coverlay 1c has with predetermined compartment every the perforation 1e that limits within it.

Coverlay mechanism for stripping 3 has the adhesive tape supply volume 4a that is used to supply adhesive tape 4, the adhesive tape cutter 5 that is used for adhesive tape 4 is cut away, the adhesive tape pressure roller 6 that is used for adhesive tape 4 is pushed facing to coverlay 1c, is used in the adhesive tape anchoring base 7 of fixation adhesive tape 4 under the vacuum and is used for the coverlay of coverlay 1c coiling being tightened up roller 8 as coverlay 1c when multilayer film 1 is peeled off.Being used for fixing the stationary roll 9a of coverlay 1c and control roll 9b is set at coverlay and tightens up between roller 8 and the adhesive tape pressure roller 6.

The coverlay 1c that just peels off from multilayer film 1 has tail end, the front end of the adhesive tape 4 of applying ointment or plaster on the described tail end.When coverlay 1c lining epiphragma tightened up roller 8 coilings, it hauled out adhesive tape supplies volume 4a with adhesive tape 4.When with multilayer film 1 charging, move in the position of the perforation 1e between coverlay 1c and the residual coverlay 1d above next-door neighbour's adhesive tape pressure roller 6.Before perforation 1e arrives this position, immediately adhesive tape pressure roller 6 is lifted, adhesive tape 4 is applied to the front end of coverlay 1c.

Adhesive tape 4 attracted to adhesive tape anchoring base 7 under vacuum when, adhesive tape anchoring base 7 is reduced, so that adhesive tape cutter 5 cuts away adhesive tape 4.Therefore, adhesive tape 4 is applied on the coverlay 1c that cuts away, and is applied on the coverlay 1c on the multilayer film 1, across residual coverlay 1d.Therefore, coverlay 1c is peeled off from multilayer film 1, simultaneously residual coverlay 1d is remained on the multilayer film 1.

It is structurally quite complicated to be used to carry out the apply ointment or plaster said apparatus of technology of conventional film, because adhesive tape pressure roller 6 and adhesive tape anchoring base 7 are arranged angularly.In addition, direction change roller 2 can not fastness fixing multilayer film 1.Especially, when with coverlay 1c when multilayer film 1 is peeled off, trend towards applying and peel off vibrations to multilayer film 1.Therefore, the substrate layer splenium that is positioned at the downstream of film application device develops the defect area that to peel off easily thereon.

Because adhesive tape pressure roller 6 is pushed adhesive tape 4 in the modes that contact with adhesive tape 4 linearities, so adhesive tape 4 can not utilize abundant bond strength to be applied to securely on the coverlay 1c.In addition, the film operation of applying ointment or plaster needs tediously long and time consuming maintenance, so that jointing material is removed from adhesive tape cutter 5.

For coverlay 1c is peeled off from multilayer film 1 reliably, the film application device needs the coverlay mechanism for stripping 3 in a plurality of horizontal directions that be arranged on multilayer film 1, because need be with a plurality of adhesive tapes 4 being applied on the coverlay 1c with spaced-apart locations in a lateral direction along multilayer film 1.Therefore, the film application device is expensive in big on the physical dimension and manufacturing.And, must be with a plurality of adhesive tape supplies volume 4a along the horizontal direction of multilayer film 1 with compartment every installation.Changing adhesive tape supply volume 4a also is quite complicated process.

The someone proposes to use the adhesive label with reservation shape such as rectangular strip to replace above-mentioned adhesive tape 4.For example, Japan publication publication 5-173487 discloses a kind of adhesive label, described adhesive label comprises substrate, described substrate is the form of heat-shrinking plastics film or sheet material, surface of described substrate is provided with the layer of bonding agent, and the bounding force of wherein said bonding agent can reduce by contact warm water.

The adhesive label does not need to use adhesive tape cutter 5, and adhesive tape cutter does not therefore need repairing.When the lining epiphragma tightened up unnecessary coverlay 1c that roller 8 reels and goes out of use, by being immersed in the warm water, the adhesive label can easily peel off from coverlay 1c simply.

Yet, as shown in figure 15,, only adhesive label's opposed end need be applied on the coverlay 1c if use above-mentioned adhesive label to peel off coverlay 1c.As a result, but need the swinging structure corresponding with adhesive tape pressure roller 6 and adhesive tape anchoring base 7, thereby make whole adhesive label's application device quite complicated.

78a, 78b transfers to corresponding adhesive label 10 after the suction pad 102a of suction substrate 100, the first and second

label receiver structure

78a, 78b receive from the first and second label organization of supply 58a, other of 58b adhesive label 10 subsequently.In the same manner described above, will be by the first and second label receiver structure 78a, the suction pad 88 of 78b attracts and the adhesive label 10 of maintenance transfers to first and second 90a of label distribution mechanism, the suction pad 102b of the suction substrate 100 of 90b.

At first and second 90a of label distribution mechanism, among the 90b, attract and keep two adhesive labels by corresponding suction substrate 100.Afterwards, give motor 94 energisings, so that removable substrate 96 is moved (referring to Figure 11) along guide member 92 on direction shown in the arrow B.One suction pad 112 aligns after the placement in suction substrate 100 and label adhesion mechanism 108, starts cylinder 98 and will aspirate substrate 100 and lift.Being sucked the suction pad 102a attraction of substrate 100 and the adhesive label 10 who keeps has facing to the label surfaces of inhaling pad 112 maintenances.

Then, inhale pad 112 and begin to attract adhesive label 10, inhale pad 102a thus and discharge adhesive label 10.Adhesive label 10 transfers to suction pad 112 from inhaling pad 102a thus.Then, will aspirate substrate 100 placement of aliging with another label adhesion mechanism 108, and the suction pad 102b that will be sucked substrate 100 attracts and the adhesive label 10 that keeps transfers to the suction pad 112 of another label adhesion mechanism 108.

As mentioned above, the suction pad 112 of label adhesion mechanism 108 attracts and keeps adhesive label 10 label surface.Then, first and second 90a of label distribution mechanism, 90b is withdrawn in the given retracted position.Part cutter 36 is placed on the end of travel on the direction shown in the arrow B 1 or on the retracted position of the end of travel on the direction shown in the arrow B 2.

Then, on the direction shown in the arrow A, during charging, give motor 116 energisings of mobile unit 114 with low velocity, on direction shown in the arrow A, move synergistically with photosensitive web 22 to make translational table 52 by removable substrate 118 when photosensitive web 22.At this moment, in each label adhesion mechanism 108, start cylinder 110 and inhale pad 112 to reduce, thus the precalculated position on photosensitive web 22, and bonding the suction filled up 112 adhesive labels 10 that attract and keep.

Particularly, as shown in Figure 8, adhesive label 10 is glued fast to across the preceding stripping portion 30aa of residual 30b of diaphragm 30 and back stripping portion 30ab.

After the adhesive label 10 with predetermined quantity is adhered to photosensitive web 22, separate photosensitive web 22 by the mechanism 42 of beating, thereby the tension variation that the photosensitive web 22 that prevents to supply is subjected to is fed to mechanism for stripping 44 continuously with photosensitive web 22 then.In mechanism for stripping 44, as shown in figure 12, when the basilar memebrane 26 of photosensitive web 22 attracted to suction drum 132, on photosensitive web 22, diaphragm 30 is peeled off, stay residual 30b on photosensitive resin layer 28.The diaphragm 30 that peels off is winding to diaphragm and tightens up (see figure 2) on the unit 134.

At this moment, because photosensitive web 22 is kept securely by suction drum 132, therefore the photosensitive web 22 in suction drum 132 downstreams is not transferred in the vibrations that produce when photosensitive web 22 separates when diaphragm 30.Therefore therefore, such vibrations are not transferred to engaging mechanism 46, prevent effectively that the zone of difference quality from appearring in the laminated portion of glass substrate 24, as the strip flaw district, or the zone etc. that shows irregular density.

By mechanism for stripping 44 diaphragm 30 is being peeled off from basilar memebrane 26, staying on photosensitive resin layer 28 after residual the 30b thus, photosensitive web 22 is fed to engaging mechanism 46.The glass substrate 24 that has been preheated with compartment in one after the other being charged to engaging mechanism 46.In the time of in being charged to engaging mechanism 46, glass substrate 24 enters rubber rollers 136a, between the 136b, contacts with the photosensitive resin layer 28 of photosensitive web 22 simultaneously.Therefore, glass substrate 24 is held under the setting pressure between the 136b at rubber rollers 136a, and photosensitive resin layer 28 is by heating and melting and be transferred and promptly be laminated on the glass substrate 24 thus.

Under following condition, photosensitive resin layer 28 is laminated on the glass substrate 24: photosensitive resin layer 28 is in the speed charging of 2.7m/min. (1.0m/min. to 10.0m/min.),

rubber rollers

136a, 136b is heated to the temperature of 130 ℃ (80 ℃ to 140 ℃), and hardness with 50 (40 to 90),

rubber rollers

136a, 136b apply the pressure (line pressure) of 250N/cm. (50N/cm. to 400N/cm.), and photosensitive web 22 is subjected to the film tension force of 120N.

As shown in figure 13, shift the glass substrate 24 that photosensitive resin layer 28 is arranged on it and have the opposed end that is covered by corresponding residual 30b.Therefore, when photosensitive resin layer 28 was transferred to glass substrate 24,

rubber rollers

136a, 136b were not stained by photosensitive resin layer 28, but photosensitive resin layer 28 is adhered on the glass substrate 24 with the shape of picture frame with being cleaned.Between a glass substrate 24 and glass substrate subsequently 24, photosensitive web 22 being cut (severed) afterwards by tablet cutting mechanism 48, basilar memebrane 26 and residual 30b are peeled off from glass substrate 24, prepare photosensitive laminate 144 thus.

According to the present embodiment, use each adhesive label who all has rectangular strip 10.As shown in Figure 1; each adhesive label 10 has the first bonding zone 10b; 10c and non-bonding zone 10a; the described first bonding zone 10b; 10c is separately positioned in the longitudinal relative end portion of adhesive label 10 in the face of the reverse side (adhesive surface) of releasing sheet 14; and heart is placed in the first bonding zone 10b among the described non-bonding zone 10a, between the 10c, is attended by residual 30b of diaphragm 30.Each adhesive label 10 also has and is arranged on the first bonding zone 10b, the second bonding zone 10d between 10c and the

non-bonding zone

10a, 10e.

Therefore, by the

first bonding zone

10b, 10c; adhesive label 10 can be easily be engaged with each other the preceding stripping portion 30aa of diaphragm 30 and back stripping portion 30ab; the second bonding zone 10d simultaneously, 10e to be covering residual 30b and stripping portion 30aa, and the border concerns setting (referring to Fig. 3) between the 30ab.Adhesive label's adhesion mechanism 40 is simple and economic structures, and is not needing under the situation that adhesive label 10 is placed along part cutting area 34 pinpoint accuracy ground with respect to photosensitive web 22 bonding reliably adhesive label 10.

Particularly, as shown in Figure 3, if the distance h of the second bonding zone 10e between front end on the direction shown in the arrow A and appropriate section cutting area 34 is big, and the adhesion of the second bonding zone 10e (bounding force) is also big, then as stripping portion 30aa, when 30ab peels off by adhesive label 10, trend towards producing stick-slip motion.Has when they form the crackle that produces as fruit part cutting area 34, then the vibration that causes owing to this stick-slip motion of photosensitive resin layer 28 and peeling off easily.

Yet according to the present embodiment, the second bonding zone 10d, the bounding force of 10e are set to than the first bonding zone 10b, the degree that the bounding force of 10c is little.Particularly, the print cycle number of times of control printing binder dissolving China ink is to dissolve the second bonding zone 10d, the bonding agent of 10e.Be set to 100% bonding agent dissolution degree when the process of bonding agent of the non-bonding zone 10a of dissolving, and will dissolve the first bonding zone 10b, when the process of the bonding agent of 10c is set to 0% bonding agent dissolution degree, then obtain as shown in figure 14 the bonding agent dissolution degree and the relation between the adhesion.

Adhesion uses probe tack detecting device (ASTM-D-2979) to measure, and this probe tack detecting device is by following operation: diameter is that the SUS probe of 5mm is loaded by the hollow cylinder counterweight, and its most advanced and sophisticated glue face that faces toward is pushed.After the tip of probe keeps predetermined period of time facing to the glue face, probe is broken away from (peeled off) from the glue face.When probe from the glue emaciated face from the time, measure the viscosity of glue face.

If the technology that is used for dissolved adhesive is at the second bonding zone 10d, the last bonding agent dissolution degree with 25% of 10e carries out, the second bonding zone 10d then, and the adhesion of 10e is expressed as 800g, and the first bonding zone 10b, the adhesion of 10c is expressed as 1170g.

Therefore, even reduce by the second bonding zone 10d, the bounding force of 10e, and increase distance h, and also prevent effectively at stripping portion 30aa, produce stick-slip motion when 30ab separates by adhesive label 10, and prevent peeling off of photosensitive resin layer 28.

The

second bonding zone

10d, 10e are can be on respect to the feedstock direction of part cutting area 34 bonding on the position relatively flexibly, thereby adhesive label 10 need be not bonding under strict degree of accuracy.The

second bonding zone

10d, 10e need not prepare under strict degree of accuracy yet, therefore the cost manufacturing adhesive label 10 that can reduce.

Adhesive label 10 is not limited to have rectangular strip, and can have circular opposed end, maybe can have the core that band eyed structure or width reduce or increase, and does not engage as long as this structure does not hinder the stripping portion of diaphragm 30.

According to the present embodiment, use adhesive label roll 12 with adhesive label 10, described adhesive label 10 with compartment every being applied on the elongated releasing sheet 14.When adhesive label roll 12 is fed to the label peeling position, the first and second

label receiver structure

78a, 78b work is with the adhesive label 10 who holds requirement.

In case adhesive label roll 12 runs out of, can be at the first and second label organization of

supply

58a, 58b installs new adhesive label roll 12 in each.Crossing on the photosensitive web 22 horizontal corresponding bond locations of separating, not necessarily must use a plurality of adhesive label rolls.As a result, preparation facilities 20 has simple relatively structure generally, thereby new adhesive label roll 12 can easily be installed.

Consider the environment repellence and help adhesive label 10 recovery, adhesive label 10 the first bonding zone 10b, the 10c and the

second bonding zone

10d, 10e has the water-soluble binder layer.Tighten up the diaphragm 30 of reeling unit 134 and adhesive label 10 when being placed on water, warm water, buck etc. when middle by the diaphragm of mechanism for stripping 44, can easily separate each other.In addition, if the first bonding zone 10b, the 10c and the

second bonding zone

10d, 10e uses the heat-peelable bonding agent, and then diaphragm 30 can easily separate by heating each other with adhesive label 10.

If adhesive label 10 is made by identical resin material with diaphragm 30, and use identical water-soluble binder,, simplified the operation of discarded and recycle thus then as adhesive label 10 with diaphragm 30 goes out of use or during recycle, they needn't separate.

If adhesive label 10 is made by paper (if in clean room handle then be cleaning paper), adhesive-bonded fabric etc., then adhesive label 10 can prepare quite cheaply, and recycle easily.Because adhesive label 10 base material is heat-shrinkable, therefore in cycle of treatment again, adhesive label 10 can easily be stripped from out under the situation about heating not have.

In embodiment of the present invention,, preparation facilities 20 is described for photosensitive resin layer 28 heat of single elongated photosensitive web 22 are transferred to glass substrate 24.Yet the present invention is not limited to illustrated preparation facilities 20.Principle of the present invention can also be applied to two or more photosensitive resin layer heat that are in the elongated photosensitive web of parallel relation can be shifted other preparation facilities on the same glass substrate.

Although of the present invention one preferred embodiment of determining shows in detail and describes, should be appreciated that under the situation of the scope that does not deviate from appended claim, can carry out various changes and modification to disclosed embodiment.
