Coating head unit 30 comprises syringe 31, nozzle 70, range sensor 33, Y-axis driver element 34 and Z axis driver element 35.Syringe 31 holds coating.Nozzle 70 is communicated with syringe 31 and discharges coating.Range sensor 33 adjacent nozzles 70 arrange, with the interval between gaging nozzle 70 and substrate S.The effect of Y-axis driver element 34 is along Y direction moving nozzle 70 and range sensor 33.The effect of Z axis driver element 35 is vertically (Z-direction) moving nozzle 70 and range sensor 33.
The coating that holds scheduled volume in syringe 31.Be contained in the form that coating in syringe 31 is fluid sealant, make by powder phase frit and organic solvent are mixed.Syringe 31 can be connected to the pressure source (not shown), and the coating can being contained in syringe 31 by nozzle 70 under the pressure that is fed to syringe 31 inside from pressure source is discharged to substrate S.Syringe 31 can with nozzle 70 one, maybe can be independent of nozzle 70 and arrange and be connected to nozzle 70 via independent passage subsequently.
As shown in Figure 2, passage 71 is formed in nozzle 70 to be communicated with syringe 31, outlet 72 be formed on nozzle 70 towards the end of substrate S to be communicated with passage 71.This structure allows the coating P in syringe 31 to flow along passage 71 under the pressure that is fed to syringe 31 inside, then is discharged to substrate S by outlet 72.
In addition, planar section 73 is formed on nozzle 70 towards the end of substrate S with the mode adjacent row outlet 72 of the upper surface that is parallel to substrate S.Outlet 72 and planar section 73 form at grade.According to this structure, when nozzle 70 moved with respect to substrate S, coating P discharged from outlet 72, makes coating P be coated to substrate S.In this course, the planar section 73 of coating P contact nozzle 70.Therefore, coating P is by planar section 73 levelings of nozzle 70, and as shown in Figure 3, the upper surface that is coated to the coating P of substrate S is shaped as the plane of the upper surface that is parallel to substrate S.
About being coated to the coating P of substrate S, its height H p and width W p basis are preset to be applied to size or the shape of the substrate S of product, height H p is the height apart from the upper surface of substrate S, width W p be coating P upper surface along with nozzle 70 with respect to the width on the vertical direction of the moving direction of substrate S (applying the direction of coating P).
At this, adjust the process of the height H p of coating and undertaken by the interval of also vertically adjusting between substrate S and nozzle 70 based on the driving that utilizes the measured substrate S of range sensor 33 and the interval between nozzle 70 to control Z axis driver element 35.
In addition, the process of width W p of adjusting the upper surface of coating P arranges nozzle 70 by the predetermined width Wp according to the upper surface of coating P planar section 73 is along carrying out with respect to the width W n on the vertical direction of the moving direction (the coating direction of coating P) of substrate S and the area of planar section 73 with nozzle 70.
As the width W n of planar section 73 during less than the predetermined width Wp of the upper surface of coating P, as shown in Figure 4, coating P can be along rising on the side of nozzle 70 in coating procedure, the upper surface of the coating P that makes irregular groove to be formed on to be coated to substrate S.Therefore, due to this problem, when a pair of substrate S is bonded together, be difficult to keep the interval between a pair of substrate S constant, and bubble undesirably is formed between a pair of substrate S.Therefore, as shown in Figure 2, the width W n of the planar section 73 of nozzle 70 preferably is equal to or greater than the predetermined width Wp of the upper surface of coating P.That is, preferably, the area of the planar section 73 of nozzle 70 is equal to or greater than the area with the contacted coating P of planar section 73.
In addition, as shown in Figure 2, the width W n of planar section 73 makes planar section 73 can effectively will be applied to corresponding to the flow velocity of the coating P that discharges from outlet 72 the upper surface leveling of the coating P on substrate S greater than the internal diameter of outlet 72.Preferably, the width W n of planar section 73 is at least 1.5 times of internal diameter of outlet 72.
