Like this, in this embodiment, be provided with fine motion Z axle driver element 20a, independent Z axle driver element 20b and shared Z axle driver element 20c as Z axle driver element, thus, a specified applicator head 15 is moved up and down, and can make two applicator heads 15 that are located on the specified Z axle retention tab 20bc move up and down identical distance simultaneously, can make whole applicator head 15 move up and down identical distance simultaneously, the state in the time of can be according to the coating in the film 1 selects to carry out the driving of some Z-directions.
Here, when applying action on the film 1 on being adsorbed on absorption platform 10, laser range finder 25 (Fig. 2) is measured the distance between the nozzle 15b (Fig. 3) of spuing of the surface of this film 1 and applicator head 15 non-contactly by optics, fine motion Z axle driver element 20a carries out drive actions to be made applicator head 15 move to Z-direction to adjust this film 1, distance between the nozzle 15b spues, so that this film 1, the distance between the nozzle 15b of spuing becomes the distance of regulation, but at film 1, the distance between the nozzle 15b of spuing surpasses the scope that can adjust by the drive actions of fine motion Z axle driver element 20a and under situation about can't adjust, next, independent Z axle driver element 20b begins drive actions, adjusts film 1, distance between the nozzle 15 spues.In this case, on an applicator head 15 that becomes on the Z axle retention tab 20bc of driven object, can adjust film 1, distance between the nozzle 15b spues, at another applicator head 15 upper films 1, spue distance between the nozzle 15b also under the situation of ranging offset of regulation, fine motion Z axle driver element 20a carries out drive actions, adjust this applicator head 15 film 1, distance between the nozzle 15b spues.
Exist also can't adjust film 1 by the drive actions of independent Z axle driver element 20b, under the situation of the applicator head 15 of the distance between the nozzle 15b that spues, shared Z axle driver element 20c carries out drive actions, but this shared Z axle driver element 20c is used for the film 1 to applicator head 15 when also beginning to apply action on film 1 being adsorbed on absorption platform 10, the distance that spues between the nozzle 15b is carried out initial setting.
Fig. 5 is the figure of the concrete example that drives of the Z-direction of the applicator head 15 in the presentation graphs 2, for the additional same tag of the corresponding part of above-mentioned accompanying drawing and the repetitive description thereof will be omitted.
In the figure, from its width (Y direction), in film 1, produce the section difference d that the bending etc. of film 1 causes
1, form the section difference d that circuit etc. causes in advance
2Protuberance, section difference d
3Recess.Here, be made as d
1＞d
2, d
3, the distance of the regulation between the nozzle 15b that spues of film 1 and applicator head 15 is made as D.
As described above, fine motion Z axle driver element 20a absorbs the mechanical alignment error of each applicator head 15, eliminates the alignment error of the applicator head 15 see, still, owing to be formed on the existence of circuit on the film 1 etc. in advance, also has a section difference d sometimes on film 1 in addition
2Protuberance, section difference d
3Recess, make the distance between the nozzle of spuing of in this concave, convex portion film 1 and applicator head 15 also become regulation distance D be fine motion Z axle driver element 20a.
In addition, in film 1, produce bending at width sometimes.By pressing the dual-side portion of film 1 by pressure bar 13,14 by above-mentioned film, this bending of having corrected film 1, but such as shown, sometimes because a section difference d
1And the dual-side portion of film 1 produces ripple to the upside expansion.This ripple produces on the width of film 1 easily, but be difficult on the length direction of film 1, produce, and situation about can't tackle in fine motion Z axle driver element 20a is many, therefore adjust by independent Z axle driver element 20b, so that the distance that spues between the nozzle 15b of film 1 and applicator head 15 can not produce deviation owing to the ripple of the main width of this film 1, adjustment is listed in two applicator heads 15 of X-direction along this corrugation rows, promptly be installed in the distance between nozzle 15b and the film 1 of spuing of two applicator heads 15 on the identical Z axle retention tab 20bc, make the distance of regulation become D.
In addition, deal with under the situation of this ripple in the driving that can utilize fine motion Z axle driver element 20a, in this ripple, the measurement result of laser range finder 25 becomes much at one on identical Z axle retention tab 20bc, in this case, also can move these applicator heads 15 to Z-direction simultaneously by independent Z axle driver element 20b.
Switching under the altered situation of the thickness of film 1 or in order to prevent that spray nozzle clogging from carrying out what is called when giving up action etc. in the service action owing to section, under the situation that whole applicator head 15 is moved up and down together, carry out the driving of the Z-direction of shared Z axle driver element 20c.
In addition, the effect of each above Z axle driver element 20a～20c is main, is not limited thereto, and can also change purpose a little and applies flexibly this 3 kinds of Z axle driver elements.
Return Fig. 4, on linear guides 29a, 29b, be provided with and be used to Y-axis driver element 30 that stand 28 is moved to Y direction.By the driving of this Y-axis driver element 30, stand 28 moves to Y direction, accompanies therewith, and independent Z axle driver element 20b and shared Z axle driver element 20c move to Y direction, and whole Z axle retention tab 20b keeps mutual compartment of terrains to move to Y direction.Thereby whole applicator heads 15 moves to Y direction with identical speed therefrom simultaneously.
When the coating do not carried out in the film 1, applicator head 15 is set to its orientation that spues nozzle 15b (Fig. 3) becomes the state that is parallel to X-direction, but, need to change the orientation of nozzle 15b of spuing sometimes according to the coating situation of the coating material on the film 1 26 (Fig. 2).In this case, come spin coated 15 by θ axle driver element 21 shown in Figure 2.
Fig. 6 is the vertical view of this state of expression, for also the repetitive description thereof will be omitted with the additional same tag of the corresponding part of above-mentioned accompanying drawing.
In the figure, the driving by θ axle driver element 21 makes applicator head 15 anglec of rotation α, and the orientation of the nozzle 15b that spues of these applicator heads 15 becomes the state that relative X-direction has been offset angle [alpha].Like this, when making applicator head 15 anglec of rotation α, the interval along X-direction of this nozzle 15b that spues dwindles becomes cos α doubly.Thereby, when a plurality of nozzle 15b that spue that utilize this applicator head 15 when Y direction applies simultaneously, compare during with state before the spin coated 15, the interval of the coating track of these nozzle 15b that spue is narrowed cos α doubly, can make in this way under situation about applying with narrower track spacing.
In addition, as shown in Figure 4, when each applicator head 15 is in the state that is parallel to X-direction (is α=0 degree, the direction that sets of the nozzle 15b that spues in the applicator head 15 shown in Figure 3 is the direction that is parallel to X-axis) time, the end of these applicator heads 15 is in the overlapping state of the last branch of X-direction, thus, the whole nozzle 15b that spue in whole applicator heads of first, the 2nd group all become equal interval at the interval of this X-direction.For example shown in Figure 3, as the interval of the orientation of establishing the nozzle 15b that spues (below be called arrangement pitch) during for P, in state shown in Figure 4, the interval of the X-direction between the nozzle 15b that spues of left end (perhaps right-hand member) of other applicator head 15 that spues nozzle 15b and be configured in the right side (perhaps left side) of this applicator head 15 of the right-hand member of certain applicator head 15 (perhaps left end) also equates with the interval of the nozzle 15b that spues in the applicator head 15, is made as interval P.
In addition, as shown in Figure 6, also identical under the situation that makes each applicator head 15 anglec of rotation α, the interval of the nozzle 15b that spues in the applicator head 15 becomes Pcos α, but in this case, the interval of the X-direction between the nozzle 15b that spues of left end (perhaps right-hand member) of other applicator head 15 that spues nozzle 15b and be configured in the right side (perhaps left side) of this applicator head 15 of the right-hand member of certain applicator head 15 (perhaps left end) also becomes Pcos α.This realizes in the following way: with the rotation of applicator head 15, the driving by X-axis driver element 24 (Fig. 2) makes applicator head 15 move to X-direction, so that approaching mutually on X-direction.
Under the situation of coating coating material 26 (Fig. 2) in the zone of the film 1 that is being adsorbed in absorption platform 10 by applicator head 15, use a plurality of applicator heads 15 to apply simultaneously sometimes.In this case, the interval of the coating track by making each the nozzle 15b that spues in this zone narrows down, can apply uniformly as a whole, but also must make the interval of this coating track also narrower sometimes than the interval P of this orientation of the nozzle 15b that spues in the applicator head 15, in this case, as shown in Figure 6, by rotating each applicator head 15 interval of interval and desirable coating track of the X-direction of the nozzle 15b that spues is coincide.
In addition, setting can rotating range based on the applicator head 15 of θ axle driver element 21 (Fig. 2), even applicator head 15 can be rotated in the rotating range at this, the arrangement of the nozzle 15b that spues at the 15a place, lower surface of applicator head 15, as a whole also between Z axle retention tab 20bc, directly mutually opposed with the face of film 1.
Fig. 7 is the figure that represents to apply like this state of the applicator head 15 of track when also narrower than the interval P of the orientation of the nozzle 15b that spues in the applicator head 15, this figure (a) is the vertical view of the part of the film 1 on the expression absorption platform 10, this figure (b) amplifies the part of the A among this figure of expression (a) and the vertical view of the relation between the nozzle 15b that spues in each applicator head 15, the 31st, the area of application, the 32nd, edge part, the 33rd, coating track.In addition, for also the repetitive description thereof will be omitted with the additional same tag of the corresponding part of above-mentioned accompanying drawing.
In this figure (a), in film 1, when being located on absorption platform 10 by coating portion 17 (Fig. 1), set rectangular-shaped the area of application 31 of regulation number, at each the area of application, 15 pairs of these rectangular box-like edge parts of applicator head, the 32 coating coating materials 26 (coating material 26 of this edge part 32 is fixed by rubber heater 22 (Fig. 1) heating) of at first use regulation, then, the inside to edge part 31 in each the area of application 31 applies coating material 26.Like this, under the situation that forms rectangular box-like edge part 32, the part along Y direction at this edge part 32 moves applicator head 15 by Y-axis driver element 30 to Y direction, and the specific nozzle 15b that spues by specific applicator head 15 applies coating material 26.
In addition, edge part 32 in the part of X-direction, followingly apply like that.That is, each applicator head 15 is configured on the different Z axle retention tab 20bc, so its position is offset in Y direction successively.Therefore, when when Y direction moves each applicator head 15, each applicator head 15 sequentially arrives the part along X-direction of edge part 32 with different timings.Therefore, by the coating material 26 that spues from the nozzle 15b that spues that arrives this edge part 32 along the applicator head 15 of the part of X-direction, by each applicator head 15 part along X-direction of application edge portion 32 sequentially, form the edge part 32 of the X-direction that has applied coating material 26.
In addition, as illustrated among Fig. 7 (b), in the area of application 31, consistent for the interval in the interval of X-direction and the figure that carries out the Y direction coating by each applicator head 15 of the nozzle 15b that spues that makes each applicator head 15 along the coating track 33 of this Y direction, be made as and make each applicator head 15 rotate the state of predetermined angular α.In this case, even identical applicator head 15, the relative X-direction tilt angle alpha of the orientation of its nozzle 15b that spues, therefore moving to Y direction under the situation of applicator head 15, the timing along the part unanimity of X-direction of respectively spue nozzle 15b and the edge part 32 of identical applicator head 15 is different.Therefore, when applicator head 15 has been in the state of angle [alpha] like this, the spue nozzle 15b consistent in this applicator head 15 the coating material 26 that spues with the part along X-direction edge part 32.Thus, in each applicator head 15, be arranged in wherein a plurality of discharge head 15b sequentially at the coating material 26 that spues on the part of X-direction of edge part 32.
Thus, even be under the state that the relative X-direction of the arrangement of the nozzle 15b that spues of applicator head 15 tilts, also along the part coating coating material 26 along X-direction of edge part 32.
The coating of the coating material 26 in this edge part 32 then, is described according to Fig. 7 (b).
In this edge part 32, apply equably along the coating track 33 that is parallel to Y direction.In this case, as the Q that is spaced apart that establishes these coating tracks 33, and when using a plurality of applicator heads 15 in edge part 32, to apply simultaneously, under the also big situation of the interval Q of the arrangement pitch P of the nozzle 15b that spues that establishes each applicator head 15 ratio coating track 33, make each applicator head 15 rotation satisfy the angle [alpha] of Q=Pcos α by this θ axle driver element 21, and as described above, adjust the position of the X-direction of each applicator heads 15 by X-axis driver element 24, so that the equating with the interval Q of coating track 33 evenly and at intervals of the nozzle 15b that in the integral body of these applicator heads 15, spues.
By in each applicator head 15, setting this state, move a plurality of applicator heads 15 to Y direction, and, can side by side apply coating material 26 along the whole coating tracks 33 in the area of application 31 by the nozzle 15b that spues in the width of the X-direction that is included in the area of application 31 among the nozzle 15b that spues of these applicator heads 15.Therefore, can carry out the coating of the area of application 31 by once the moving of Y direction of applicator head 15.In this case, certainly much less, each applicator head 15 relative Y direction tilts, and therefore makes the coating of the nozzle 15b that respectively spues of each applicator head 15 begin regularly, apply the stop timing difference according to this inclination.Under by the situation that once moves the coating to carry out the area of application 31 integral body,, applicator head 15 is moved in the direction with for the first time opposite of Y-axis get final product as long as make film 1 to the Y direction displacement.
In addition, even make applicator head 15 rotate to its can rotating range to greatest extent, the spue interval of X-direction of nozzle 15b can not become under the situation of interval Q of coating track 33 yet, the position of further adjusting the X-direction of applicator head 15 makes the part of adjacent applicator head 15 overlapping on Y direction, and the position of X-direction that the nozzle 15b that spues of another applicator head 15 is arranged in the interval of the X-direction of the nozzle 15b that spues of an applicator head 15 of two applicator heads 15 that overlap each other, thereby can reduce the interval of X-direction of the nozzle 15b that spues of these applicator head 15 integral body, thus, can make each nozzle 15b that spues of applicator head 15 identical with narrow at interval coating track 33.But, in this case, 1 Y direction by applicator head 15 move simultaneously that the width in the zone of coating diminishes, need to repeat that the Y direction of applicator head 15 moves more than 2 times.
Following technology had been proposed in the past: as shown in Figure 7, under the kind needs according to the coating object reduce situation that the interval of coating track of the nozzle 15b that spues of applicator head 15 applies, if apply by the mobile of Y direction, then then moving applicator head 15 to X-direction is provided with ensuing coating starting position, moves applicator head 15 to Y direction once more from this position and carries out coating the area of application.But the processing time in this technology will increase several times and efficient is low.
Relative therewith, in this embodiment, X-direction tilts relatively according to make applicator head 15 rotations by θ axle driver element 21, thereby can change the interval of X-direction of the nozzle 15b that spues of applicator head 15, the interval of the coating track 33 in this interval and the area of application 31 is equated, can make a plurality of nozzle 15b that spue, further make a plurality of nozzle 15b that spue of a plurality of applicator heads 15 be applied to the coating action simultaneously, can improve the coating operating efficiency significantly.

At first, the roller that makes and roll out in the film roll 2 moves with the rubber heater 22 that heater 23 and absorption platform become one, and begins heating (step 101).Then, film 1 stops at the position of absorption platform 10, carries out its interim location (step 102).Take home position on the film 1 by the video camera 19 of the applicator head 15 of selected appointment, handle calculating the film 1 of interim positioning states and relative position side-play amount (step 103) between the stand 28 of applicator head 15 is installed by image.According to this relative position side-play amount that calculates, calculate moving and coating starting point position and the coating end point position (step 104) of each nozzle 15b that spues of applicator head 15 of X-axis driver element 24.
Then, move whole applicator head 15 to Y direction, the periphery pattern (step 105) that becomes edge part 32 in the application pattern that coating finally should apply by Y-axis driver element 25.This periphery pattern is the peripheral part of the area of application 31, becomes a mouthful word shape in Fig. 7.Here, the roller that film 1 is rolled out in the film side roller 2 heats in advance with heater 23, and by with the rubber heater 22 that becomes one of absorption platform more reliably or the temperature higher than this prior heating heat, therefore in the coating material 26 of the peripheral part of the mouth word shape that is coated on film 1, solution evaporates and drying at short notice, will form edge part 32 accurately.
Then, the spacing Q with the more very thin nozzle 15b that spues carries out the coating of the inside pattern of the area of application 31.
That is, rotate by θ axle driver element 21 and to move each applicator head 15, so that the mode that becomes desired value Q to the projection spacing of X-axis is provided with its anglec of rotation α (step 106).Under this state, move whole applicator head 15 by Y-axis driver element 25 to Y direction, apply (step 107) simultaneously along each coating track 33.
Here, as shown in Figure 6, move each applicator head 15 by 21 rotations of θ axle driver element, thereby can reduce the coating interval of X-direction, it is the interval of X-direction of the nozzle 15b that spues of each applicator head 15, but under the coating of wanting further to reduce X-direction situation at interval, on the basis of the judgement of having carried out whether needing the spacing skew and having applied (step 108), further reduced coating coating (" Y " of step 108) at interval if desired, then spacing is offset to X-direction by X-axis driver element 24, move whole applicator head 15 by Y-axis driver element 25 to Y direction, apply along each coating track 33 by each nozzle 15b that spues, thus depicting interior pattern (step 109).
In addition, under the situation about applying in the coating compartment of terrain of wanting to reduce Y direction (" N " of step 108), on the basis of the judgement that needs the spacing skew whether and apply (step 110), further reduced coating (" Y " of step 110) at interval if desired, spacing is offset to the Y direction, after having changed the coating starting point of Y direction, move whole applicator head 15 by Y-axis driver element 25 to Y direction, thereby apply inner pattern (step 111).
Judge whether spacing skew coating is all finished, if finish (" Y " of step 112), then make each whole applicator heads 15 to turning back to original state (being state shown in Figure 4) (step 113) with above-mentioned rightabout rotation by θ axle driver element 21, the stop roller action (step 114) of heater 23 and rubber heater 22, tenth skill.
If (" N " of step 112) also all do not finished in spacing skew coating, then from judging (step 108) repetitive operation once more.
Here, if carry out the skew of half spacing, then follow the coating number of times that moves based on Y direction of the driving of Y-axis driver element 25 to become initial coating and repeat coating totally 2 coatings for 1 time, if carry out the coating of 1/4 spacing skew, then become initial coating and repeat coating totally 4 coatings for 3 times.Can on X-direction and Y direction, determine this side-play amount respectively.
