Description

Manufacturing installation, manufacture method and the plate of the plate of band functional film

Technical field

The present invention relates to cathode ray tube and so on, its surface has on the plate surface of curvature on the directions in 3 dimensions, the technology of paste functionality film equably.The present invention includes plate, the manufacture method of plate and the manufacturing installation of plate etc. made with this technology.Certainly, the technology of the present invention also is applicable in the occasion that has paste functionality film on the plate surface of curvature on the two-dimensional directional.

Background technology

For example, in the process of making cathode ray tube or other display unit, often on the plate surface of display image, paste one deck functional film.This is to prevent charged, as to improve penetrance auxiliaring effect and the cause that prevents effects such as reflecting because functional film has.

The method of paste functionality film has two kinds substantially on the plate surface of cathode ray tube.

At first, first method as shown in figure 33, the method that is to use ultraviolet hardening resin 2D that functional film 2 is pasted on the surface of the plate 1A of cathode ray tube 1.This method at first is that ultraviolet hardening resin 2D is coated on the surface of plate 1A of cathode ray tube 1, and then lays functional film 2 thereon, again with rolling the 3P pushing, makes functional film 2 temporary transient stickups onboard.After temporary transient the stickup, again cathode ray tube 1 is moved on in the not shown UV irradiation stove, carry out ultraviolet irradiation, make ultraviolet hardening resin 2D sclerosis, thereby functional film 2 is sticked on the surface of plate 1A.

In addition, the 2nd kind of method has following method as shown in figure 34,, uses the functional film 2 that scribbles binding agent 2A in advance in one side that is, makes function film 2 stick on the lip-deep method of plate 1A of cathode ray tube by rolling the 3P pushing.In this method, be to cover after the lip-deep peeling paper 2B of binding agent 2A (with reference to Figure 35) on the one side of functional film 2 takes off, again functional film 2 is laid on the surface of plate 1A of cathode ray tube, and then with rolling 3P pushing functional film 2, and make and roll 3P and move to the roller direction of advance, like this, functional film 2 just Pasting live.In this example, functional film 2 is to use the film that is formed with hard conating 2E on a side surface of PETG (PET) film etc. shown in the sectional drawing of Figure 35.

Above-mentioned two kinds of methods all are provided with mechanism and make pushing force curvature along plate 1A surface on the roller direction of advance of roller 3P keep certain substantially.For example, on roller above-below direction and roller direction of advance, install with plate 1A surface, on the roller direction of advance 2 approximate interpolation mechanisms of curvature, along with the plate surface on above-below direction change and make the pushing force of roller keep certain.In addition, under the situation that the pushing force of roller realizes with hydraulic cylinder, the precision regulator of control pushing usefulness is installed on the roller, the pushing force that makes roller along with the plate surface on above-below direction change and keep certain.Again, accurately pushing force is controlled under the situation of certain level, uses 2 interpolation mechanisms of above-mentioned roller above-below direction and roller direction of advance simultaneously and control the precision regulator that pushes usefulness at needs.

Above-mentioned two kinds of existing common issue with of method are, as being representative with cathode ray tube etc., the plate surface all has curvature on 3 dimension directions situation can occur.

For example, the plate surface of shape shown in Fig. 3 b, be the plate surface has regulation in the XZ plane curvature, in the YZ plane, have under the situation of rectangle section and (it is called the surface that has curvature on 2 dimension directions), utilize the above-mentioned pushing effect that is provided with the roller of 2 interpolation mechanisms, functional film can be sticked on the plate surface substantially fully equably.

But, under the situation of (it being called the plate surface that has curvature on the 3 dimension directions) of the plate surface of the spherical shape shown in the (a) and (b) of Figure 37, be that the plate surface all has under the situation of curvature in the XZ plane, in the YZ plane, with the total length shown in Figure 37 (b) is that 1 pushing is rolled 3P with functional film during toward the pushing of this plate surface, on the Z direction.In the pressure maximum of the highest point roller at top, plate surface, so the varied in thickness of roller 3P is big.On the contrary, along with close to plate surface both ends EP1, EP2, the varied in thickness of rolling 3P is little, in the pushing force minimum of both ends roller.

In this case, want to change the method for attaching of the functional film of both ends EP1, EP2 side, will strengthen the roller pushing force of both ends EP1, EP2, so it is just very big to be applied to the pressure of top highest point, can make plate surface damaged, therefore, only adding the large roller pushing force can not address this problem.

Like this, will produce following problems, that is to say, when using the method that cylindric pushing in the past rolls, make the curvature of rolling direction of advance that the roller pushing force is controlled at certain level even be provided with mechanism along pushing, in the both ends side on the inner panel surface, plane of rolling direction of advance perpendicular to pushing, pushing force also can produce difference, equably the paste functionality film.

For example, use the functional film mounting method (calling the ultraviolet hardening resin mounting method in the following text) of ultraviolet hardening resin, because the plate of cathode ray tube has complicated curvature on 3 dimension directions, the both ends on the plate surface in the plane of rolling direction of advance perpendicular to pushing, descend onboard on the direction (Figure 37 is the Z direction), between the extreme higher position at its top and bottom position, several millimeters difference in height is arranged, so roller pushing force difference between both ends is very big.Therefore as a result, the variable thickness sample of the ultraviolet hardening resin layer of both sides, and easy residual bubble are difficult to guarantee equably, paste functionality film in high quality.

Secondly, be that this method also exists and the same problem of above-mentioned ultraviolet hardening resin mounting method significantly about the functional film mounting method (calling the binding agent mounting method in the following text) of use binding agent.That is, the plate surface of cathode ray tube has under the situation of curvature on the directions in 3 dimensions, compares with the extreme higher position with the both ends on plate surface in the vertical plane of direction of advance is rolled in pushing, and the pushing force of roller differs bigger.Its result can not paste functional film on the little face of pushing force fully.Be inner alveolate state, accomplish that the paste functionality film is extremely difficult equably.

About this point, as prior art at plate surface paste functionality film, though at the open communique of Japan is that the spy opens flat 7-326289 number and the spy opens on the flat 7-45186 communique and published, but owing to do not understand fully the problems referred to above fully, so propose the means that settle the matter once and for all in these technology, these technology can not adopt eventually.

The problems referred to above not only are created on the plate of cathode ray tube and so on, and this problem is the problem that must produce when 3 dimensions have paste functionality film on the plate surface of curvature on the directions.For example, during the paste functionality film, also same problem can appear on the plate surface of glass pane of automobile and so on.Therefore, people urgently expect to solve this outstanding question, and the new solution of plate that can make the band functional film of high-quality occurs.

The present invention develops in order to address the above problem, its main purpose is for a kind of plate being provided and making the manufacturing installation of this plate and make the method for plate with this manufacturing installation, and this plate is to tie up the plate that is pasted with functional film equably on the plate surface that has curvature on the directions and can gives full play to the original function of functional film 3.

Best example of the present invention

1. embodiment 1

In the present embodiment, tie up the plate surface that cathode ray tube is regarded on the plate surface that has curvature on the directions as 3.

If represent the technological thought of present embodiment with pattern, then as shown in Figure 1.Promptly, as shown in Figure 1, when rolling plate surface 1S that portion 3 sticks on cathode ray tube with functional film 2 and go up with pushing here, substantially keeping certain in order to make pushing roll portion 3 perpendicular to the roller pushing force in the YZ plane of roller direction of advance RD (X), the invention provides a kind of novel pushing and roll the structure of portion 3, the elasticity that portion is rolled in this novel pushing is rolled easily along the curvature distortion on the plate surface on above-mentioned YZ plane.

The roller part of portion 3 is rolled in pushing, is made of roller and central shaft (axial region), and wherein, roller is to be made of the cylindrical shape elastic caoutchouc with centre bore, and central shaft inserts in the centre bore.In addition, also between a part of insertion portion of this axial region and centre bore, be provided with clearance C LR and become hollow type.The setting of this clearance C LR realizes that by following structure the profile that is about to above-mentioned axial region is made following shape: (1) has the shape of the concave curvature of the curvature that is similar to plate surface IS in the YZ plane perpendicular to roller direction of advance RD; Or (2) have the shape of at least one section band concave step that is similar to this curvature.In this case, the curvature of the axial region of band curvature, number of steps, shoulder height and the step spacing of axial region with the level are different and different according to the curvature of plate surface IS in the YZ plane of cathode ray tube.

This pushing roller structure shown in Figure 1, certainly ultraviolet hardening resin mounting method and binding agent mounting method all can use, but for convenience of explanation, below just the latter describe.

In addition, in theory, as long as elasticity is rolled and is not turned round, at least establish clearance C LR between the profile (outer surface) of a part of insertion portion of internal diameter (being the wall of centre bore) that the elasticity of push plate surface IS side is rolled and above-mentioned axial region and get final product, so-called here profile (outer surface) means the outer surface of pushing face one side that elasticity is rolled.

Below, according to accompanying drawing the pushing that the paste functionality film uses of having of present embodiment is rolled the manufacturing installation of the plate of portion and is elaborated.

Fig. 2 is the end view of overview of the functional film adhesive portion of display plate manufacturing installation, and Fig. 3 is the front view of the board manufacturing apparatus seen from arrow A 1 direction of Fig. 2.Again, Fig. 4 rolls the sectional drawing of the overview of portion 3 by the pushing of pushing being rolled after portion 3 cuts off perpendicular to the ZY face direction of Fig. 2 paper.

In addition, the essential structure of portion 3 and peripheral mechanism formation thereof is rolled in Fig. 2-pushing shown in Figure 4, not only can be used for the binding agent mounting method, equally applicable to the ultraviolet hardening resin mounting method.

Fig. 2-X, Y, Z direction shown in Figure 4 is called the 1st direction or roller direction of advance, the 2nd direction and the 3rd direction.

As shown in Figure 2, towards upside (+Z direction), and target ray tube 1 is fixed with the surperficial IS (functional film stickup face) that makes the plate 1A of dome shape.In addition, pushing is rolled portion 3 and is installed on support cantilever (arm) plate 7 that fuses with horizontal mobile mechanism 4, and the effect that portion 3 is rolled in above-mentioned pushing pushes, it is sticked on above the plate 1A functional film 2.

As shown in figure 35, binding agent 2A is arranged on the functional film 2, but in above-mentioned Fig. 2, do not represent binding agent 2A, the diagram abridged with binding agent is also arranged in figure shown below.

As Fig. 2, shown in Figure 3, spill horizontal mobile mechanism 4 is fixed on the two ends of supporting cantilever slab 7, and the bottom of this mechanism 4 is embedded on guide rail or the guide rod 6 with state slidably, and this guide rail or guide rod are parallel to directions X and lay.The two ends of two guide rails 6 are fixed, and are not shown.In addition, after this mechanism 4 is activated the actuating force effect of portion 8, just on guide rail 6, move along roller direction of advance directions X, so, roller pushing portion also moves horizontally on roller direction of advance directions X, above-mentioned drive division 8 is made of motor etc., the control signal CNT8 that this motor sends according to control panel described later and entry into service.

In addition, also can this LM guide rail structure, lay 2 linear axes but be parallel to directions X, each horizontal mobile mechanism 4 is combined on each linear axes, roller pushing portion 3 can be that directions X moves to the roller direction of advance also like this.

Again, the type of drive that moves horizontally, except utilizing ball stud, also available toothed belt drives.

In addition, elevating mechanism 5 is installed in supports on the cantilever slab 7 that its inside is provided with pushing force source (being hydraulic cylinder) takes place here.The high accuracy adjuster 9 that pressure regulation is used is connected on the hydraulic cylinder by pipe arrangement 9A, through this high accuracy adjuster adjusted pressure that pressurizes, hydraulic cylinder is driven, this elevating mechanism 5 passes to pushing by the leading section 5A that is connected this elevating mechanism 5 on the hydraulic cylinder with above-mentioned actuating force and rolls the maintaining part 3P of portion 3, so just making pushing roll the 3A of portion (is ± the Z direction) lifting among the figure on above-below direction.

Pushing is rolled portion 3 as shown in Figure 4, is that to roll 3A be that main body constitutes for the cylindrical shape elasticity of R with conductivity silicon rubber system, external diameter for example.This elasticity is rolled 3A, and being provided with internal diameter around its central shaft (axis) 3CA is centre bore 3E R1, that connect the above-mentioned 3A of rolling both ends of the surface.Central shaft (axial region) 3B inserts this elasticity and rolls in the centre bore 3E of 3A, is being supported by maintaining part 3D from centre bore 3E outstanding both ends 3BE1,3BE2 in axial region 3B, can turn round, and this maintaining part is connected with the leading section 5A that the elevating mechanism 5 of portion 3 is rolled in pushing.Owing to be this structure,, the power that this elevating mechanism 5 pushes away rolls 3A downwards so just passing to elasticity as pushing force.

Again, roll in elasticity between the external diameter r or outer surface 3BS of a part of insertion portion of the wall of the internal diameter R1 of 3A or centre bore 3E and axial region 3B, be provided with gap d.Here, the shape of axial region 3BS such as following.That is, the outer surface 3BS of the 3rd part P3 of axial region 3B forms spill by following curvature, that is to say that its curvature and the surperficial 1S of plate 1A are being similar to perpendicular to the curvature in the YZ plane of roller direction of advance X.Clip other parts of the insertion section branch of the 3rd part P3, be the 1st, part 2 P1, P2, the 1st, part 2 has basic and internal diameter R1 equal outer diameters.Therefore, the equal diameters that the maximum gauge of axial region 3B is basic and elasticity is rolled the centre bore 3E of 3A.The curvature on surface outside the 3rd part P3 of this axial region 3B is changing perpendicular to the curvature in the face of roller direction of advance is different according to the plate surface.

For example, curvature be about 1000, diagonal is of a size of 17 inches braun tube (cathode-ray picture tube), gap d is set at about 1mm.

Fig. 5 is the block diagram with the control system of modal representation board manufacturing apparatus of the present invention.Aftermentioned each several part 10-13,8,9,20 is each control signal CNT11-CNT13, CNT8 of sending according to control panel 15, CNT9, CNT20 and driven.Control panel 15 itself is to control with program according to the control that is stored in its CD or the memory section 14.

Below, with each reference symbol among Fig. 2-Fig. 5, just describe toward the method for attaching that the surperficial 1S of the plate 1A of cathode ray tube 1 goes up paste functionality film 2 with board manufacturing apparatus of the present invention.

Fig. 6 is the vertical view during from Z direction billboard surface 1S.At first, the plate of cathode ray tube 1 surface 1S is towards upside, temporarily fixing with cathode ray tube 1 with fixed mechanism 10, then, adjust the height of plate 1A again with Z direction adjusting mechanism 11, so that the horizontal plane of plate surface 1S is with to push the horizontal plane that rolls portion 3 consistent.After the adjustment, only that the short transverse of cathode ray tube 1 is formally fixing with fixed mechanism 10 again.

Then, be ready to scribble the functional film 2 of the binding agent 2A of Figure 35 in its one side (the 1st pellicular front 2S) side, the 1st pellicular front 2S that scribbles binding agent 2A is placed on the placed side 16S that pastes platform 16 towards upside, with functional film 2, after these film 2 location, with adsorbent equipment 13 functional film 2 is adsorbed, fixes again.The absorption affinity size here is: when carrying out pushing described later and paste, absorption affinity reaches and can go up the degree that functional film 2 is extracted out from placed side 16S.After holding, as shown in Figure 7, the peeling paper 2B that covers above the binding agent 2A is taken off.Here, Fig. 7 and Fig. 8 described later are the end views of seeing from arrow A 2 one sides of Fig. 6.

As shown in Figure 6, the central portion from an end of pasting platform 16 is provided with grooving portion 17 to the other end.By this grooving portion 17, pushing is rolled portion 3 and is pushed functional film, when one side is mobile, is to carry out in certain moving range to roller direction of advance X on one side, like this, can avoid the portion of rolling 3 to take place with the situation that stickup platform 16 contacts.

Again, as Figure 6 and Figure 7, the other end of pasting platform 16 is connected on the slew gear 18, and this slew gear 18 is accepted after the actuating force of platform drive division (motor etc.) 20, is clockwise direction, counter-clockwise direction revolution just make stickup platform 16 along direction 19.

Then, as shown in Figure 8, to take the face of binding agent 2A of the functional film 2 after the peeling paper 2B off towards downside, and be not configured with the downside state of contact of functional film 2 with the surperficial 1S of the plate 1A of cathode ray tube 1, starting under this state, the above-mentioned drive division 20 of control make and paste about 180 degree of platform 16 counter-rotatings.After the counter-rotating, for the plate 1A and the functional film 2 of target ray tube 1 carries out contraposition, with cathode ray tube X, Y direction positioning and fixing mechanism 12, on the X of Fig. 8, Y direction with cathode ray tube 1 or plate 1A location and fixing.At this moment, the surperficial 1S of plate 1A does not contact with functional film 2.

Below, as shown in Figure 9, driving by elevating mechanism 5, making pushing roll portion 3 descends, making this elasticity of rolling portion 3 roll 3A contacts with an end face of functional film 2, here an end face is the end face outside the active area 2C institute restricted portion in the 1S of fingerboard surface, and an end face of functional film 2 is pressed against on the surperficial 1S of corresponding plate 1A, and functional film 2 is temporarily fixing.After temporary transient fixing, as shown in Figure 9, platform drive division 20 is driven, make and paste platform 16 and only just changeing a predetermined angular along clockwise direction, like this, paste platform 16 and just keep out of the way not with pushing and roll on the position that the actuating range of the pushing travel direction of portion 3 disturbs mutually.

After stickup platform 16 was kept out of the way, as shown in figure 10, portion's 3 limits pushing functional film 2 was rolled in pushing, paste functionality film 2 is advanced on the limit on roller direction of advance X.At this moment, with pushing roll portion 3 mobile interlocking, make and paste platform 16 clockwise direction revolution off and on.

At this moment, because pushing is rolled portion 3 and is had aforesaid gap d, so as shown in figure 11, the pushing face that elasticity is rolled 3A along plate surface 1S, be out of shape perpendicular to the curvature in the YZ plane of roller direction of advance X, the result, the thickness D2 that the elasticity at top is rolled 3A equates with thickness D1, the D3 of both ends side substantially, and it is uniformly substantially in the YZ face that elasticity is rolled the pushing force that 3A applies functional film 2, so paste functionality film in high quality.

So elasticity is rolled the curvature distortion of its easy plate surface 1S in the YZ face of 3A, this is because roll in axial region 3B and elasticity between the centre bore 3E of 3A and be provided with gap d, and this gap value equals the end (bottom) of stickup face of functional film 2 of plate surface 1S and the cause of the difference of height between other each stickup faces substantially.

In addition, as shown in figure 12, the also axial region 3B of pie graph 4 not, but constitute axial region 3C.That is, the 3rd part P3 of axial region 3C has at least the shape (having external diameter here is 2 stage portion of r1, r2) with 1 step, and the shape of this step is with similar perpendicular to the curvature of the surface of the plate in the YZ plane of roller direction of advance 1S.Number of steps, shoulder height and step spacing are set suitable value according to the curvature of plate surface 1S.

Under situation about with this axial region 3C functional film 2 being pressed against on the 1S of plate surface, though elasticity is rolled the thickness of 3A each several part and is not reached as shown in figure 11 elasticity and roll the state that the thickness D1-D3 of 3A equates substantially, but, compare with technology in the past, can make the pushing force of the whole plate surface 1S in the YZ plane more even.And, also have the processing easier advantage of the processing of axial region 3C than the axial region 3B of Fig. 4, therefore, use the pushing portion of rolling of structure also can obtain very big actual effect with Figure 12.

If comprise the axial region 3B of Fig. 4 and Figure 12, the shape facility of 3C, then can be defined as " its outer surface is to set according to the curvature perpendicular to the plate surface in the plane of roller direction of advance ".

The inventor of this patent when adopting conventional art (the solid type pushing roller portion 30 of Figure 33, Figure 34) and when adopting this pushing of hollow type to roll portion 3 faultlessly (equably) pushing force that functional film sticks on the surperficial 1S of plate is had much difference actually, confirm by experiment.Its comparative result is shown in Figure 13.

Here, experimental condition is as follows.That is:

(1) the rubber material of hollow type, solid type roller is all made identical with hardness.

(2) functional film 2 uses film shown in Figure 35.

(3) allowed band of pushing force is set at less than the cathode ray tube in this test structure and conducts oneself with dignity.

The structure of this experimental rig as shown in figure 14.That is, the explosion-proof band of circumvolution 1B on the plate outer wall of cathode ray tube 1 with the protuberance 1C supporting cathode ray tube 1 on each bight that is installed in this explosion-proof band 1B, measures the bonding pushing force then.In this case, when surpassing the cathode ray tube deadweight owing to the stickup pushing force, protuberance 1C just produces distortion, so result in this case is judged as NG, and judges both qualities.

Result by Figure 13 clearly illustrates that, 1/3 or 1/2 of the pushing force the when pushing force when using the pushing of this hollow type to roll portion was rolled for use pushed in the past, and also pushing is in the past rolled and all is judged as NG.This means when using this pushing to roll portion 3, in the YZ plane, can push equably.

As mentioned above, according to board manufacturing apparatus of the present invention, when functional film being sticked on the plate surface of cathode ray tube, use elasticity cylindraceous to roll, to have the axial region of concavity curvature or the axial region that has one section concavity step shape at least of similar this curvature will be inserted in the centre bore that elasticity rolls, above-mentioned concavity curvature and plate surface approximate perpendicular to the curvature in the plane of roller direction of advance, and between the wall of the outer surface of axial region and centre bore, be provided with the gap.Like this, when pasting the pushing functional film, elasticity is rolled easily and is out of shape along producing perpendicular to the curvature in the plane of roller direction of advance of plate surface.At this moment it is basic identical that elasticity is rolled the variable quantity of the deflection of each several part of 3A self or thickness.Therefore, perpendicular to the whole plate surf zone in the plane of roller direction of advance, the roller pushing force keeps certain value basically.

Its result, use the ultraviolet hardening resin mounting method, the thickness of ultraviolet hardening resin layer is certain substantially in perpendicular to the plane of roller direction of advance, and is difficult for residual bubble, therefore can provide the plate that evenly and in high quality is pasted with functional film from the teeth outwards.

In addition, the binding agent mounting method because certain substantially perpendicular to the lip-deep roller pushing force of the plate in the plane of roller direction of advance, so can not produce the not face of bonding, and is difficult for generation bubble, paste functionality film equably too.

At this, ultraviolet hardening resin 2D (Figure 33) in the ultraviolet hardening resin mounting method and the binding agent 2A (Figure 34) in the binding agent mounting method are generically and collectively referred to as " bonding source ".This point is also general in embodiment 2 described later.

In addition, if the principle of being based on revising the profile of axial region 3B, 3C as Fig. 4, as shown in Figure 12 and being provided with gap this scheme of α can consider that also the gapless solid type elasticity that the curvature according to above-mentioned plate surface changes in the past in advance rolls this method of thickness.But, when adopting this method, must be with the precision processing elastic caoutchouc of for example 1/100mm, big this new problem of difficulty has become significantly in the processing.This point for axial region, can easily realize the precision in this processing, therefore, we can say that Fig. 4, method shown in Figure 12 are the technology of practicality.

2. embodiment 2

In the present embodiment, plate has such surface, promptly ties up the surface that all has curvature on the directions 3, with the plate of this plate as cathode ray tube.In addition, the technical overview that is adopted is here represented with ideograph, as shown in figure 15.Below, utilize Figure 15 to set forth the core of present technique.

Promptly, when the plate surface 1S (surface is sphere shape) that functional film is sticked on cathode ray tube with main press-rolling portion 3 goes up, in order to make and the 1st and the 2nd end E1 perpendicular to the plate surface of the YZ Plane intersects of roller direction of advance RD (X) fork, roller pushing force on the E2 keeps certain value substantially, from roller direction of advance RD, rear position at main press-rolling portion 3, and respectively at the 1st and the 2nd end E1, on the top position of E2 side, dispose the 1st, the 2nd follows displacement rolls portion 41 with pushing, 42, with main press-rolling portion 3 interlocks of going ahead of the rest, make the 1st and the 2nd to follow displacement with pushing the portion 41 of rolling, 42 along each end E1, the curvature of the roller direction of advance RD of E2 side is followed displacement.Therefore, in each end E1, E2 side, functional film 2 at first is subjected to the pushing (promoting mainly pressure) of main press-rolling portion 3, further be subjected to corresponding portion 41,42 is rolled in displacement with pushing the pushing of following then, like this, apply best pushing force, substantially equably the paste functionality film.

1st, the 2nd follow the structure that displacement rolls portion 41,42 with pushing and also can further do following improvement.Promptly, can the plate surface be pushed with only angle for the curvature changing along the roller direction of advance of each end E1 of the face that rolls that makes the portion of respectively rolling 41,42 and plate surface 1S, E2 side is corresponding, can have the roller maintaining part of even mechanism respectively rolling to be provided with in the portion 41,42.

In addition, respectively roll the roller centre hole that constitutes by the cylindrical shape elastic caoutchouc of portion 3,41,42 and insert between the central shaft (axle) in this centre bore, also can be provided with the gap.

The hardness and the 1st, the 2nd that all pressures amount+elastic caoutchouc of balancer structure rolls is followed displacement and is rolled the installation site (setting angle and installing space) of portion 41,42 with pushing, according to the plate surface 1S of cathode ray tube perpendicular to the curvature of the 1st and the 2nd end E1, E2 in the plane YZ of roller direction of advance RD and variation thereof and different.

In addition, even the curvature of plate surface 1S is under the situation of 3 dimension directions, the curvature of each end E1, E2 side is along the variation of roller direction of advance hour, on the basis of fixing above-mentioned balancer structure, by the above-mentioned interlock that rolls portion 3,41,42, also functional film 2 can be sticked on the 1S of plate surface.

In order to regulate the pushing force of the portion of respectively rolling 3,41,42 respectively independently, can also to be provided with each pushing portion of rolling is carried out the adjuster that pressure controlled high accuracy pressure regulation is used independently again.

Again, even the plate surface configuration is a spherical form shown in Figure 37, as long as utilize the 1st to follow displacement pushing and roll portion 41 and main press-rolling portion 3, at first move while pushing along roller direction of advance RD, the stickup of the functional film 2 that the curvature of the 1st end E1 side in the modifying factor YZ plane causes is bad, then, as following, change two and roll portion 3,41 configuration, promptly from the opposite direction (directions X) of roller direction of advance RD, roll portion 41 and be positioned at the rear of main press-rolling portion 3, and be positioned at E2 side top, the 2nd end specifically, again (X) along the opposite direction of roller direction of advance RD, main press-rolling portion 3 in front and make two to roll portion 3,41 interlocks, paste functionality film 2 on the 1S of plate surface also can obtain the effect the same with the situation of Figure 15.In this case, though flow chart, activity duration increase, as long as with one follow displacement with push roll just passable.

Again, the shape of plate in the YZ plane only a side end side, for example only the 1st end E1 side has curvature partly; In this case, do not need the 2nd of Figure 15 to follow displacement certainly and roll portion 42 with pushing.

Below, to board manufacturing apparatus shown in Figure 15 and use the board fabrication method of this device to carry out more specifically, detailed explanation.

This pushing roller structure is the same with embodiment 1, and these two kinds of mounting methods of ultraviolet hardening resin mounting method and binding agent mounting method can use.In the example of following art, use the latter's mounting method.

Figure 16 is the summary side elevation that carries out the functional film adhesive portion of this board manufacturing apparatus of expression, Figure 17 represents that following displacement from the main press-rolling portion 3 and the 1st, the 2nd that arrow A shown in Figure 16 3 directions are seen rolls the position relation of portion 41,42 and the general view of structure thereof with pushing, and the part is represented with section.At this, general name the 1st and the 2nd is followed displacement and was rolled portion at 41,42 o'clock with pushing, is defined as to follow displacement with pushing the portion of rolling.Figure 18 is the skiagraph of the main press-rolling portion 3 seen from arrow A 4 directions of Figure 17, and Figure 19 rolls the skiagraph of portion from the displacement of following that arrow A 5 directions of Figure 17 are seen with pushing.Figure 20 is a front view of seeing horizontal mobile mechanism 5 and track 6 etc. from arrow A 6 directions of Figure 16, and Figure 21 is perpendicular to the paper direction of Figure 16, promptly a Y direction is seen the end view of these mechanisms 5,6.

Figure 16-Figure 21 is the sticker that comes the paste functionality film with the binding agent mounting method, but the main press-rolling portion 3 shown in these figure and follow displacement with push roll portion 4 (41,42) basic structure too applicable to the occasion of ultraviolet hardening resin mounting method.

As shown in figure 16, with the surperficial IS of plate 1A towards upside (+Z direction), and fixed negative pole ray tube 1.In addition, above plate 1A, main press-rolling portion 3 and the 1st, the 2nd follows displacement rolls portion 14 with pushing, 42 are installed in the part 1 of supporting cantilever slab 7 respectively, part 2, above the 3rd part, the effect of this main press-rolling portion 3 is pushed (it is called promotes mainly pressure) to functional film 2, stick on the IS of plate surface by binding agent functional film 2, the 1st, the 2nd follows displacement rolls portion 41 with pushing, 42, from promoting mainly the roller direction of advance X of the portion of rolling 3, be positioned at the rearward position of main press-rolling portion 3, be configured in the 1st end E1 of plate surface IS respectively, the 2nd end E2 side.And, horizontal mobile mechanism 5 is embedded on the track or guide rod 6 that is parallel to the directions X laying with the state that can slide, roll portion 4 with pushing and follow and promote mainly nip drum and move horizontally along roller direction of advance (among the figure+directions X) limit pushing functional film 2, limit so that make main press-rolling portion 3 be in advance, follow displacement, above-mentioned horizontal mobile mechanism 5 is connected with these both ends of rolling the support cantilever slab 7 of portion 3,4 of support.Except main press-rolling portion 3 adds that following displacement for 2 rolls portion 4 with pushing and can be installed in linkedly and support on the suspended wall plate 7 this point, the structure of horizontal mobile mechanism of rolling portion 3,4 equally also can use linear axes to replace the LM guide rod basically as described in the embodiment 1.

As Figure 17, shown in Figure 180, main press-rolling portion 3 is made of following part: external diameter is that the columnar main elasticity of R is rolled 3A, and it has the centre bore 3E that for example is made of conductivity silicon rubber; Central shaft, be axial region 3B, this a part is inserted the centre bore 3E that main elasticity is rolled 3A; Main elasticity is rolled maintaining part 3C, and it is supporting pivotally from both ends 3BE1, the 3BE2 of the outstanding axial region 3B of centre bore 3E; Promote mainly splenium 3D, its leading section 3DE rolls maintaining part 3C with main elasticity and is connected, and has to produce to promote mainly the main hydraulic cylinder that pressure is used.And, promote mainly splenium 3D and be installed on the part 1 of supporting cantilever slab 7.

As Figure 16, Figure 17, Figure 20, shown in Figure 21, from the roller direction of advance (+when X) seeing main press-rolling portion 3, the the 1st and the 2nd follows displacement rolls portion 4 (41 with pushing, 42) be in the rear position of main press-rolling portion 3, and be configured in plate surface IS and the 1st and the 2nd end E1, E2 side top position respectively independently perpendicular to the YZ crossing on the same level of roller direction of advance X.

Promptly, the 1st follows displacement rolls the length of the length direction that portion 41 is parallel to the Y direction and is (L1+L11) with pushing, it is installed on the part 2 of supporting cantilever slab 7, the central shaft of its 1st 4D1 of pushing portion be positioned at leave main press-rolling portion 3 rearward (directions X side), the central shaft spacing is on the 1st end E1 side of the 3rd distance L 3.Here, from the 1st end E1 distance L 11 〉=0 of ledge laterally.Be positioned at the 1st on the IS of plate surface from the 1st end E1 and follow displacement with the 1st distance L 1＞0 that pushes till the end that rolls portion 41.

In addition, the 2nd follows displacement rolls portion 42 with pushing and is installed on the 3rd part of supporting cantilever slab 7, make it leave main press-rolling portion 3 to-directions X, the central shaft spacing is on the position of the 4th distance L 4, and the central shaft of its 2nd 4D2 of pushing portion is positioned at the 2nd end E2 top.This pushing is rolled portion 42 and is (L2+L22) along the length of the length direction of Y direction, and the 2nd distance L 2＞0 is from the length L 22 〉=0 of the 2nd end E2 ledge.

Here, L3=L4 follows displacement for two and is positioned at same YZ plane with pushing the central shaft 4CA1, the 4CA2 that roll portion 41,42.Usually L3=L4, but L3 ≠ L4 also can, at this moment, the 1st, the 2nd distance L 1, L2 are not limited in 0＜L1＜L/2,0＜L2＜L/2 scope yet.

Follow structure that displacement rolls portion 4 with pushing as shown in figure 19, it is made of following part: elasticity is rolled maintaining part 4A, and it has balancer structure (hereinafter referred to as voltage balancer); Columnar elasticity is rolled 4B, and it is the same with main press-rolling portion 3 to have centre bore 4F, and this elasticity is rolled by for example conductivity silicon rubber and made; Central shaft (axial region) 4C, its part is inserted elasticity and is rolled in the centre bore 4F of 4B, and its both ends 4CE1,4CE2 are supporting pivotally with maintaining part 4A; The 4D of pushing portion (its leading section is 4DE), its effect is to produce to follow the pushing force that displacement is used with the pushing portion of rolling.Symbol 4CA is the central shaft that elasticity is rolled 4B.

In addition, the 1st, the 2nd follows displacement with pushing when rolling the each several part symbolically of portion 4, adds 1,2 at the right-hand member of each symbol of Figure 19, and additional " the 1st ", " the 2nd " such title are called.

As following displacement, to roll the axonometric drawing of portion 4 with pushing promptly shown in Figure 22, and voltage balancer 4E comprises following part: axle 33; Notch plate 31, it is fixedly installed on the front end 4DE of the 4D of pushing portion; Handle part 32, it is fixedly installed on the central portion of the top 4AUS of maintaining part 4A, is used to control axle 33, and this handle part 32 can turn round integratedly with axle 33.That is, the two ends of axle 33 are bearing on the bearing 30 with state insertion pivotally, and this bearing 30 is located at respectively on the notch plate 31.Therefore, handle part 32,33 curvature changing according to plate surface IS by the revolution of direction shown in the arrow A 7, change the gradient that elasticity is rolled the central shaft 4CA of 4B.

In addition, 1st, the 2nd voltage balancer 4E1,4E2 are random composed components, for example the curvature of the 1st, the 2nd end E1, E2 is not having on the roller direction of advance X under the situation about changing, need not establish voltage balancer yet, in this case, even establish even device, also can fix with 29 couples of voltage balancer 4E of fixed mechanism shown in Figure 22.

As shown in figure 20, the splenium 3D, the 1st that promotes mainly at main press-rolling portion 3 follows the 1st 4D1 of pushing portion and the 2nd that displacement rolls portion 41 with pushing and follows on each hydraulic cylinder of displacement rolls portion 42 with pushing the 2nd 4D2 of pushing portion, by pipe arrangement 9A, 39A, 40A the pressure regulation high accuracy adjuster that carries out its pressure adjustment is set independently respectively.By adjuster control part 38 these adjusters of control.It also is random that these adjusters 9,39,40 are set, particularly roll when being provided with voltage balancer 4E in the portion 4 with pushing following displacement, 1st, the pushing force on the 2nd end E1, the E2 is along with the height change along roller direction of advance each end E1, E2 changes, in order to make its pushing force keep certain by voltage balancer 4E, must suitably adjust to be applied to and follow displacement and roll pressure on the hydraulic cylinder of portion 4 with pushing, therefore, setting is followed displacement and is rolled the adjuster 39,40 of portion's 4 usefulness with pushing in this case, and very big advantage is arranged in practicality.That is,, therefore establish adjuster and make pressure keep certain because along with the variation of voltage balancer 4E, the pressure in the hydraulic cylinder also changes.

Figure 23 represents the block diagram of the control system of this device.Basically with shown in Figure 5 identical, here, increased and followed portion 4 is rolled in displacement with pushing lifting control.

Regard to down with the method for attaching of this panel assembly and describe toward the last paste functionality film 2 of surperficial IS of plate 1A.

At first, as the vertical view of seeing from arrow A 8 directions of Figure 16 is shown in Figure 24 model utility ground, with the surperficial IS of the plate 1A of cathode ray tube 1 towards upside (+Z direction), fix with fixed mechanism 10 temporary transient target ray tubes 1, adjust the height of plate 1A again with mechanism 11, so that the horizontal plane of the surperficial IS of plate 1A is consistent with the horizontal plane of main press-rolling portion 3.After the adjustment, only the short transverse of target ray tube 1 is carried out formally fixing.

Then, shown in the end view of Figure 25, the functional film 2 that scribbles binding agent 2A on the one side is placed on the placed side 16S that pastes platform 16, makes the top of binding agent 2A, after positioning, hold fixed function film 2 with device 13 towards last example.After holding, take the peeling paper 2B (Figure 25) above the binding agent 2A off.All the situation with embodiment 1 is identical for the absorption affinity of shape, function and the functional film 2 of stickup platform 16.

Then, as shown in figure 25, with taken off peeling paper 2B functional film 2 binding agent 2A on the side (Z direction) that faces down, and, for the plate surface 1S that makes cathode ray tube 1 comes the downside of functional film 2, utilize platform drive division 20 to make and paste platform 16 counter-rotatings.After the counter-rotating, in order to make cathode ray tube 1 and functional film 2 aligned positions, the position of the directions X of target ray tube 1 and Y direction positions, and fixed negative pole ray tube 1.At this moment, the surperficial IS of plate 1A does not contact with functional film 2.

Subsequent, as shown in figure 26, main press-rolling portion 3 is descended, making main elasticity roll 3A contacts with an end face that is equivalent to the functional film 2 beyond the scope of the active area 2C defined of plate surface IS, this end face of functional film 2 is pressed against on the IS of plate surface temporary transient fixed function film 2.

After temporary transient the fixing, as shown in figure 27, make the 1st, the 2nd to follow displacement and roll portion 41,42 with pushing and descend, such as shown in figure 27 then, stickup is closed 16 keep out of the way with main press-rolling portion 3 and two and follow displacement with pushing on the position that the pushing direction of advance actuating range that rolls portion 4 do not disturb.

After pasting platform 16 and keeping out of the way, as shown in figure 28, make main press-rolling portion 3 in front, and make main press-rolling portion 3 and two follow displacement to roll portion 4 and under the pushing state, advance paste functionality film 2 along the roller direction with pushing.At this moment, according to the situation of advancing of the portion of rolling 3,4, platform 16 is retreated by phased manner.

In this case, owing to follow displacement and roll portion 4 and have voltage balancer 4E for two with pushing, therefore as shown in figure 29, according to the both ends E1 in the YZ face of surperficial IS, the variation that the curvature of E2 is produced along the roller direction of advance, voltage balancer 4E is displacement like that as mentioned above, the 1st, the 2nd elasticity is rolled 4B1, the central shaft 4CA of 4B2 is parallel to the tangential direction TD (TD1 on this plate surface that is urged, TD2) under the state, the 1st, the 2nd elasticity is rolled 4B1,4B2 pushes this plate surface, therefore, even the both ends E1 in the YZ plane of plate surface IS, the curvature roller direction of advance of E2 change (its end one side curvature minimum on directions X), follow displacement and also keep certain with pushing the pushing force of rolling portion 4, even the face of the functional film 2 that still can not paste by the pushing of main press-rolling portion 3, roll the pushing of portion 4 with pushing by following displacement, also can promptly evenly and in high quality paste well.

In addition, as mentioned above, because main press-rolling portion the 3, the 1st and the 2nd is followed displacement and rolled portion 41,42 with pushing and be respectively equipped with the high accuracy adjuster 9,30,40 of adjusting pushing usefulness, therefore can make pushing force basic maintenance necessarily in the Zone Full of the surperficial IS of the plate 1A of cathode ray tube 1.

Insert main elasticity and roll Fig. 4 of the profile of insertion portion of the axial region 3B in the centre bore 3E of 3A such as embodiment 1 or shown in Figure 12, also can form according to the curvature of the surface of the plate in YZ plane IS.When this variation is used for the little situation of above-mentioned curvature, work effectively, add the effect of embodiment 1 on the effect of present embodiment again.

In addition, about following displacement with pushing the structure of rolling portion 4, also the main press-rolling portion 3 with embodiment 1 is the same, in order to have gap d, can revise the shape of axial region 4C.In this case, the profile of axial region 4C can decide according to the curvature of the plate in YZ plane surface IS, under the little situation of this curvature, follows displacement with pushing this variation of rolling portion 4 as described in the embodiment 1, plays a part useful.That is, elasticity is rolled and is provided with gap d between the contoured surface of the centre bore 4F of 4B and axial region 4C (d1, when d2) becoming hollow type, even above-mentioned curvature is little, elasticity is rolled 4B and also is easy to generate distortion, can make pushing force keep certain.

This variation is shown in Figure 30, Figure 31.

As mentioned above, according to embodiment, on the plate surface of cathode ray tube during the paste functionality film, because on the basis of promoting mainly nip drum 3 in the past, at the 1st of main press-rolling portion 3 rear sides of seeing from the roller direction of advance, the 2nd end side, set and have the 1st of balancer structure 4E, the 2nd follows displacement rolls portion 41 with pushing, 42, portion 41 is rolled in this pushing, 42 can be along the both ends E1 of roller direction of advance in the IS of plate surface, the curvature of E2 is followed displacement, and be provided with pressure regulator 9 in each pushing portion of rolling, 39,40, be used to make the roller pushing force to keep certain, therefore, in roller pushing force, keep certain substantially in the Zone Full of roller direction of advance perpendicular to the both ends of the plate in the YZ plane of roller direction of advance surface IS.

Its result, adopt the ultraviolet hardening resin mounting method, because the thickness of ultraviolet hardening resin layer, keeping certain with the both ends E1 that pitches perpendicular to the YZ Plane intersects of roller direction of advance, E2 place are also basic, and be difficult for residual bubble, therefore can provide the plate that evenly and in high quality is pasted with functional film.

In addition, with the binding agent mounting method too, only be difficult to paste with main press-rolling portion in the past, near plate end perpendicular to the YZ crossing on the same level of roller direction of advance, can not produce stickup not face, and be difficult for to produce bubble, can be evenly and stick in high quality on the IS of plate surface with functional film.

Again, in the above description, end E1, the E2 of Figure 17 are defined as the 1st end, the 2nd end respectively, corresponding, to follow displacement and roll portion 41,42 with pushing and be called the 1st and follow displacement and roll portion, the 2nd with pushing and follow displacement and roll portion, but also these can be defined conversely with pushing.

(to the example of embodiment 1,2 co-variations)

In the above description, make plate surface IS towards upside (+Z) fixed negative pole ray tube 1 like that, but also can be shown in Figure 32 (example of Application Example 1), make plate surface IS towards downside (Z) fixed negative pole ray tube 1 like that, make main press-rolling portion 3 (situation of embodiment 1) then or replace and make main press-rolling portion 3 and 2 follow displacement to roll portion 4 (situation of embodiment 2) with pushing and under the pushing state, move paste functionality film 2 along roller direction of advance X with gap.Also can obtain same effect in this case.

More than, elaborated feature of the present invention with accompanying drawing, but these setting forth an aspect that just illustrates invention form of the present invention eventually, the present invention is not limited to these set forth.That is, except this is illustrational, the example of various correction or variation only otherwise break away from technical scope of the present invention (visual field), can be realized.
