As described later, nozzle 14 can move along the carrying direction (X-direction) of vertical direction (Z-direction) and sheet material W.Moving of the nozzle 14 carrying direction (X-direction) by sheet material W, and traveling above sheet material W will be coated on the surface of sheet material W from the coating liquid of ejiction opening ejection.And nozzle 14 moves by vertical direction (Z-direction), and and sheet material W between form the coating gap of regulation.Keep the coating gap and make the carrying direction traveling of nozzle 14, will be coated on the sheet material W from the coating liquid of ejiction opening ejection thus along sheet material W.And nozzle 14 can also move along the direction (Y direction) with the carrying direction quadrature of sheet material W except described two directions.
Fig. 2 is the figure that represents the brief configuration of nozzle moving mechanism with the edge and the cross section of the direction crosscut carrying face of carrying direction quadrature.Workbench 25 is arranged on pallet 24(regularly with reference to Fig. 1) on, height and position is constant.Nozzle moving mechanism is formed on this workbench 25.Nozzle moving mechanism is made of nozzle elevating mechanism 16, the first nozzle horizontal mobile mechanism 17 and the second nozzle horizontal mobile mechanism 18.
On workbench 25 and in the outside in the carrying path of sheet material W, with respect to the direction of the carrying direction quadrature of sheet material W and construct flame XZ axle robot.This robot uses as an example has 2 linear actuator of normal axis.By this robot, realize respectively making the slide block 26 that keeps nozzle 14 along the carrying direction (X-direction) of vertical direction (Z-direction) and sheet material W mobile the nozzle elevating mechanism 16 and the first nozzle horizontal mobile mechanism 17.
In addition, sheet coating apparatus 1 possess except above-mentioned two directions, can also make slide block 26 along with the second mobile nozzle horizontal mobile mechanism 18 of direction (Y direction) of the carrying direction quadrature of sheet material W.In the present embodiment, the second nozzle horizontal mobile mechanism 18 is arranged between slide block 26 and the nozzle 14.In addition, also can be as another embodiment of the second nozzle horizontal mobile mechanism represented among Fig. 3, the second nozzle horizontal mobile mechanism 18 is arranged between the nozzle elevating mechanism 16 and the first nozzle horizontal mobile mechanism 17, also can as the another embodiment of the second nozzle horizontal mobile mechanism represented among Fig. 4, the second nozzle horizontal mobile mechanism 18 be arranged between pallet 24 and the workbench 25.
The second nozzle horizontal mobile mechanism 18 is as an example, has linear actuator, electric actuator, used the automatic type of drive of the linear motor, air pressure/fluid pressure type actuator etc. of air bearing, based on the manual adjusting style of feed screw, push-and-pull leading screw etc.
Once more, with reference to Fig. 1, the first coating position-detection sensor 65 is configured in the upstream side of pretreating device 30 on the carrying direction of sheet material W.The second coating position-detection sensor 66 is configured in the upstream side of nozzle 14 on the carrying direction of sheet material W.The first coating position-detection sensor 65 and the second coating position-detection sensor 66 edge by detecting sheet material W or the edge of the coated film on the upper surface that is formed on sheet material W, and be used in the control of the initial position (coating position) of nozzle 14.This coating position-detection sensor uses image processes sensor, color identification sensor, ultrasonic sensor, bar code, laser sensor, infrared ray thermal image instrument sensor as an example.
Fig. 5 represents to apply the block diagram of position control system.Coating position control section 27 is controlled the driving of carrying mechanism 10, the first nozzle horizontal mobile mechanism 17 and the second nozzle horizontal mobile mechanism 18 respectively based on the detection signal of the first coating position-detection sensor 65 and the second coating position-detection sensor 66.The position that coating position control section 27 is held nozzle 14.
Use the flow chart of Fig. 6, the coating positioning control example based on coating position control section 27 is described.At first, the edge (step S1) by the first coating position-detection sensor, 65 detection sheet material W drives carrying mechanism 10 and sheet material W is carried to the initial position of setting in order to carry out working procedure of coating (step S2).Once more, by the second coating position-detection sensor 66, detect the edge (step S3) of sheet material W, coating position control section 27 is judged in the current location of carrying direction (X-direction) top nozzle 14 of sheet material W whether skew (step S4) has been taken place from the appropriate location, be judged as when skew has taken place, make 17 actions of the first nozzle horizontal mobile mechanism and nozzle 14 is moved to this direction, thereby carry out contraposition (step S5).Next, coating position control section 27 is judged and with the current location of direction (Y direction) top nozzle 14 of the carrying direction quadrature of sheet material W whether skew (step S6) is being taken place from the appropriate location, be judged as when skew has taken place, make 18 actions of the second nozzle horizontal mobile mechanism and nozzle 14 is moved to this direction, thereby carry out contraposition.
Though this coating position adjustment also can be used when forming coated film when first on the sheet material W at uncoated, the sheet material W that is formed with coated film is being repeated coating or useful when multilayer coated.Repeat the coating or multilayer coated in, shown in the vertical view of Fig. 7, the detection position of the first coating position-detection sensor 65 and the second coating position-detection sensor 66 is not set in the edge of sheet material W, and being set in the edge of coated film, the mode that can overlap the appropriate location above coated film thus with the ejiction opening of nozzle 14 is accurately adjusted the coating position.
Referring again to Fig. 1, the structure of sheet material elevating mechanism is described.The first sheet material backing roll 20 disposes in liftable mode at the downside of carrying face T and the upstream side of the absorption platform 13 on the carrying direction at sheet material W, and on this position sheet material W is supported.The second sheet material backing roll 21 disposes in liftable mode at the downside of carrying face T and the upstream side of the absorption platform 13 on the carrying direction at sheet material W, and on this position sheet material W is supported.The first sheet material backing roll 20 and the second sheet material backing roll 21 are examples of sheet material supporting member of the present invention.The first sheet material backing roll 20 and the second sheet material backing roll 21 are accompanied by the carrying of sheet material W and driven rotation.
The first sheet material backing roll elevating mechanism 22 constitute be configured in the first sheet material backing roll 20 near, make 20 liftings of the first sheet material backing roll.The second sheet material backing roll elevating mechanism 23 constitute be configured in the second sheet material backing roll 21 near, make 21 liftings of the second sheet material backing roll.The first sheet material backing roll elevating mechanism 22 and the second sheet material backing roll elevating mechanism 23 preferably use linear actuator etc. as an example.
The driving of the first sheet material backing roll elevating mechanism 22 and the second sheet material backing roll elevating mechanism 23 is controlled by sheet material lifting control part (not shown).Sheet material lifting control part is controlled the first sheet material backing roll elevating mechanism 22 and the second sheet material backing roll elevating mechanism 23 with the time difference so that be positioned at absorption platform 13 the top part sheet material W from its carrying direction upstream side downstream side descend gradually.
With reference to Fig. 8 (A) ~ (E) and explanation based on the control example of sheet material lifting control part and sheet material absorption control part.In a series of action of following explanation, though diagram especially drives clamping device 64 and dancer mechanism 63 and sheet material W is carried out when the carrying direction applies the tension force of homogeneous.
After above-mentioned coating position adjustment, at first under the state shown in Fig. 8 (A), the first sheet material backing roll 20 and the second sheet material backing roll 21 all are positioned at sustained height, locate sheet material W is supported above leaning on than absorption platform 13.The height of the sheet material W of this moment is identical with the height of carrying face T.
Next, sheet material lifting control part drives the first sheet material backing roll elevating mechanism 22, shown in Fig. 8 (B), the first sheet material backing roll 20 is descended.The slippage of the first sheet material backing roll 20 is set at height poor of carrying face T and the upper surface of absorption platform 13.At this moment, the second sheet material backing roll 21 does not descend, and maintains initial height.Therefore, the sheet material W of top that is positioned at absorption platform 13 is supported to the inclination that upstream side is low and the downstream is high of the carrying direction with sheet material W as shown like that.
Then, shown in Fig. 8 (C) ~ (E), sheet material lifting control part drives the second sheet material backing roll elevating mechanism 23, and the second sheet material backing roll 21 is descended.It is identical with the first sheet material backing roll 20 that the slippage of the second sheet material backing roll 21 is set at.
Sheet material absorption control part with the decline of the second sheet material backing roll 21 in beginning, middle office, these three times of end with synchronous mode, make absorption platform 13 cut apart and 3 binding domains, 131 ~ 133 interim and the appending property ground actions that form along the carrying direction.Promptly, only make first binding domain, 131 actions (with reference to Fig. 8 (C)) that are positioned at upstream side in beginning, make second binding domain, 132 the appending property ground actions (with reference to Fig. 8 (D)) that are positioned at central portion in middle office, make further the appending property ground action (with reference to Fig. 8 (E)) of the 3rd binding domain 133 that is positioned at downstream in end.
Cooperation by such sheet material lifting control part and sheet material absorption control part, sheet material W is being applied under the state of tension force of homogeneous along the carrying direction, corresponding to the inclination of sheet material W diminishes from the upstream side of the carrying direction of sheet material W downstream side sheet material W is adsorbed on the absorption platform 13 successively.Thus, can prevent to produce fold, perhaps between sheet material W and absorption platform 13, produce air trapping at adsorbed sheet material W.Consequently, even have flexible sheet material W, also can form workpiece with sheets such as wafers and similarly have the applicator surface P(of level of shape stability and flatness) with reference to Fig. 8 (E).Need to prove,, then can prevent the fold that produces at sheet material W effectively if sheet material backing roll 20,21 adopts spread rolls (bow action roller).
So formed after the applicator surface P, driven nozzle elevating mechanism 16 and the coating gap that between the ejiction opening of nozzle 14 and applicator surface P, keeps stipulating.And, utilize to drive feed mechanism 15 and, be detained (liquid pearl) and form application of liquid in the coating gap from the coating liquid of the trace of nozzle 14 ejections.And, drive the first nozzle horizontal mobile mechanism 17, carrying direction along sheet material W makes nozzle 14 scan the distance of the regulation of the length that is no more than absorption platform 13 continuously or off and on, and the liquid pearl is followed moving of nozzle 14 and whole of liquid of coating or intermittent application in applicator surface P thus.
Except the action of interim and the appending property of the driving of time difference of above-mentioned sheet material elevating mechanism and a plurality of binding domains, the structure that from the top sheet material W application of force is pressed on the absorption platform 13 can be set also.For example, be the mechanism that the carrying direction along sheet material W scans for the member that is absorbed and fixed at the additional parallel line pressure of the sheet material W of absorption on the platform 13 with the direction of the carrying direction that is orthogonal to sheet material W.Use linear actuator as an example of sweep mechanism.
Fig. 9 (A) ~ (E) illustration the member of additional line pressure be the situation of pressing pressure roller.By pressure roller 28 by the axle supporting on the direction that is oriented to the carrying direction quadrature of sheet material W for rotating.Be configured in the top (with reference to Fig. 9 (A)) of carrying face T by pressure roller 28, drop to and the position that is bearing in the upper surface butt that adsorbs the sheet material W on the platform 13 by elevating mechanism (not shown), apply push (with reference to Fig. 9 (B)) of the linearity parallel to sheet material W with the direction of the carrying direction that is orthogonal to sheet material W.Pressing pressure roller 28, press pressure roller 28 and rotate also traveling (with reference to Fig. 9 (C) ~ (E)) on sheet material W from the downstream side scanning upstream of the carrying direction of sheet material W by sweep mechanism (not shown).Need to prove,, can at random set by pushing of producing by pressure roller 28, therefore can not exert pressure sheet material W by the change of inner air pressure by adopt air pressure type working cylinder etc. in the elevating mechanism portion of pressing pressure roller 28.
In addition, Figure 10 (A) ~ (E) illustration the member of additional line pressure be the situation of air jetting nozzle 29.Air jetting nozzle 29 is configured in the top (with reference to Figure 10 (A)) of carrying face T.Air jetting nozzle 29 the lower end have and the upper surface of sheet material W between keep the ejiction opening in gap.Ejiction opening is as an example but along the shape of slit of extending with the direction of the carrying direction quadrature of sheet material W, but is not defined in this, also can constitute ejiction opening by a plurality of apertures that equally spaced dispose along this direction.The air pump of air jetting nozzle 29 and force feed air etc. is connected, and utilizes from the pressure-air of ejiction opening ejection, and the air pressure of linearity that will be parallel with the direction of the carrying direction that is orthogonal to sheet material W applies (with reference to Figure 10 (B)) to sheet material W.The air jetting nozzle 29 of ejection air utilizes travel mechanism (not shown) and from the downstream side scanning (with reference to Figure 10 (C) ~ (E)) upstream of the carrying direction of sheet material W.Therefore air jetting nozzle 29 scans with the contactless state with applicator surface P, can not make sheet material W have scar, is repeating coating, can not impact coated film when multilayer coated.And, also can expect to be present in applicator surface P dust remove effect.The air pressure that is produced by air jetting nozzle 29 can utilize adjuster etc. to adjust, and by utilizing partition etc. the A/F of the ejiction opening of flowmeter or slit-shaped is changed and can adjust air ejection flow.
