< laminating apparatus >
Below, laminating apparatus 60 is described.Laminating apparatus 60 is, carries substrate 5, is fitted on substrate by the polarizing coating that film conveying mechanism 50 is carried.Although not shown, pure air is fed into the upper surface of substrate 5 but in laminating apparatus 60.That is, the rectification of katabatic drainage is carried out.Thus, can carry substrate 5 with stable state and fit.
Laminating apparatus 60 is located at the top of film conveying mechanism 50.Thus, the space saving of manufacturing system 100 can be obtained.Although not shown, but on laminating apparatus 60, be provided with the substrate carrying mechanism with transfer roller, thus, substrate 5 is transferred (being equivalent to substrate carrying mechanism by Fig. 6 first substrate conveying device 61 described later, second substrate conveying device 62) to throughput direction.
In manufacturing system 100, substrate 5 is transferred from left side, and then, from figure, the top of right side and the first film conveying mechanism 51 is transported to the top of the second film conveying mechanism 52.Substrate 5 is oblong-shapeds, the ratio of long limit and minor face without particular limitation of, but such as can make the ratio of 16: 9 ~ 4: 3.In addition, as the object lesson of substrate 5, such as, can exemplify the glass substrate panel of organic EL panel, liquid crystal cell.
Between film conveying mechanism 50 and laminating apparatus 60, there is sticking part and niproll (the first sticking part) 6,6a and niproll (the second sticking part) 16,16a respectively.Niproll 6,6a and 16,16a are the components playing a kind of like this effect: the polarizing coating after being removed by stripping film is fitted on the lower surface of substrate 5.In addition, in order to fit polarizing coating from lower surface on the two sides of substrate 5, after fitting with niproll 6,6a, switching mechanism 65 is utilized to be overturn by substrate 5.For switching mechanism 65, as aftermentioned.
Be transported to the polarizing coating of niproll 6,6a, clip bond layer and be fitted on the lower surface of substrate 5.As niproll 6,6a, the known structure such as crimping roller, backer roll can be adopted respectively.In addition, the pressure and temperature during laminating of niproll 6,6a also can suitably regulate.The structure of niproll 16,16a is also identical.In addition, although not shown, but in manufacturing system 100, preferably structure is, rolls out between portion's 1 to half-cutter have Flaw display (mark) test section from first, detects the defective polarizing coating of tool.
In addition, described Flaw display is, carry out detecting and putting on Flaw display when making the drum substrate of polarizing coating, or, utilize and be located at first compared to Flaw display test section and roll out portion 11 or the second and roll out the Flaw display assigning unit of 11a side, portion and be marked on polarizing coating.Flaw display assigning unit is made up of camera, image processing apparatus and Flaw display forming portion.First, utilizing described camera to take polarizing coating, by processing this photographing information, just can check zero defect.As described defect, specifically, if any the foreign matters such as dust, flake (Off ィ ッ シ ュ ア イ) etc.Detecting the occasion of defect, utilizing Flaw display forming portion and form Flaw display on polarizing coating.As Flaw display, with marks such as inks.

< switching mechanism >
Switching mechanism 65 is that the substrate 5 making to be carried by first substrate conveying mechanism overturns and is configured in the component on second substrate conveying mechanism.Described first substrate conveying mechanism and second substrate conveying mechanism configure to same direction.Fig. 4 is the stereographic map representing switching mechanism 65.Switching mechanism 65 has first substrate turning part (substrate overturn portion) 67 and second substrate turning part (substrate overturn portion) 68.
First substrate turning part 67 is bar-shaped, has adsorption section 66.First substrate turning part 67 can, around the axial-rotation of self, can make substrate 5 move to the vertical direction perpendicular to axle by adsorption section 66.In addition, first substrate turning part 67 is connected with second substrate turning part 68.This coupling part is drivable, changes the position of first substrate turning part 67, changes the position of substrate 5.
In addition, the structure of second substrate turning part 68 is, except two arm structures, abutment portion can horizontally rotate.Utilize two arm structures, substrate 5 can be moved along the vertical direction, utilize the rotation of abutment portion, substrate 5 can be made to rotate in the horizontal direction.
In the present embodiment, as substrate overturn portion, illustrate the structure of a substrate overturn portion 67 and second substrate turning part 68, but substrate overturn portion is not limited to this structure.Such as, as preferably form, the mechanical arm with control part can be used.Using the occasion of mechanical arm, operating due to more accurate substrate 5 can be carried out, therefore being preferably.As mechanical arm, known mechanical arm can be used.
Below, the upset of first substrate turning part 67 and second substrate turning part 68 pairs of substrates 5 is described.Figure 13 is the stereographic map of track when representing that substrate 5 overturns.Figure 13 (a) is the diagram corresponding with the state of the substrate 5 in Fig. 4.In order to easily hold the track of substrate 5, diagram eliminates adsorption section 66, first substrate turning part 67 and second substrate turning part 68.
First, substrate 5 is carried by first substrate conveying mechanism with the state of its minor face along throughput direction.As shown in Figure 13 (a), substrate 5 stops at the front of not shown first substrate turning part 67, the surface of adsorption section 66 sorbing substrate 5.Substrate 5 is last as shown in Figure 13 (d), and the minor face along the throughput direction of first substrate conveying mechanism is configured on second substrate conveying mechanism along the direction orthogonal with throughput direction.
First substrate turning part 67 and second substrate turning part 68, make substrate 5 follow curve state and move, with the state making the Status Change as the substrate 5 in Figure 13 (a) become the substrate 5 in Figure 13 (d).That is, utilize a mild action that substrate 5 is moved.Therefore, the upset of the substrate 5 of the present embodiment is not rectilinear movement, such as, be not the movement of the upset with the direction making a limit along substrate 5.In addition, this action, neither make two action continuous print action of the upset of substrate and the rotation in substrate level direction, neither carry out these two actions simultaneously.
Substrate 5 in Figure 13 (a), as shown in Figure 13 (b) ~ (d), is inner side with (in figure left side) minor face of one side, is outside is moved with (in figure right side) minor face of the opposing party.Specifically, the rotary drive system of each axle of the machinery shown in Fig. 4 is disconnected, it is the state that operator can stir each axle of machinery, in the pattern model that each shaft angle degree and the displacement of the machinery be struck are detected by sensor, as described as follows substrate 5 posture and realize each shaft angle degree of machinery of this posture and displacement is indicated by operator, and to be stored.In Figure 13 (a), mentioned by substrate 5 from the surface level residing for substrate 5, substrate moves with the state tilted, to become the outside shorter side position higher than inner side minor face.Position after substrate 5 ' expression substrate 5 moves.In addition, curve 69 represents the track of the substrate 5 after connecting between the summit corresponding by substrate 5 and substrate 5 '.First substrate turning part 67 and second substrate turning part 68 are followed curve and substrate 5 are moved.In other words, also can say that substrate moves along curvilinear path.Described curve is circular arc, is not straight line but level and smooth track.Except above-mentioned demonstration, also such embodiment can be adopted: make substrate carry out overturning each shaft angle degree of production machinery movably and displacement data along with the arc track shown in Figure 13 and be stored in advance in the ROM of control device, make mechanical action according to this data, thus make substrate mobile along with the arc track shown in Figure 13 carries out upset.
Substrate 5 finally moves to the state shown in Figure 13 (d) via the state shown in Figure 13 (b) and (c).The configuration of the substrate 5 of Figure 13 (d) is such configuration: overturn by the substrate 5 of Figure 13 (a), and being changed by the minor face along throughput direction becomes long limit.
In addition, the process of the configuration change making substrate 5 is described with Figure 14.Figure 14 (a) ~ (d) represents to utilize switching mechanism 65 and the vertical view of the process that substrate 5 is overturn.The configuration of the substrate 5 of Figure 14 (a) ~ (d) is corresponding with the configuration of substrate 5 in Figure 13 (a) ~ (d) respectively.
Figure 14 is the vertical view representing substrate 5 rotary course in Fig. 4.Figure 14 also illustrates first substrate conveying mechanism 61 and second substrate conveying mechanism 62 except switching mechanism 65.First substrate conveying mechanism 61 and second substrate conveying mechanism 62 have transfer roller, by its conveying substrate 5.In addition, first substrate conveying mechanism 61 and second substrate conveying mechanism 62 configure to same direction.That is, not there is the structure of the complexity such as L-shaped.Therefore, arranging of laminating apparatus 60 of the present invention is very easy, and area efficiency is excellent.
First, as shown in Figure 14 (a), the surface of adsorption section 66 sorbing substrate 5, the surface of substrate 5 is kept.Then, for becoming the configuration of the substrate 5 of Figure 14 (d), substrate 5 is followed curve 69 track shown in Figure 13 (a) ~ (c) and moves.After substrate 5 arrives the position shown in Figure 13 (d), after removing maintenance in the absorption by removing adsorption section 66 to substrate 5, by second substrate conveying mechanism 62 conveying substrate 5.Further, the position of Fig. 6 (a) got back to by switching mechanism 65, with same action, other substrate 5 carried successively overturn.
Adopt the switching mechanism 65 of the present embodiment, result, utilizes an action, and (1) makes substrate 5 overturn, and meanwhile, (2) are configured to along the direction orthogonal with throughput direction along the long limit of the throughput direction of first substrate conveying mechanism 61 or minor face.Therefore, utilize an action, and two Status Changes of substrate 5 can be made.
So, owing to utilizing a switching mechanism 65 to produce two effects, therefore can at shorter production substrate overturn interval time 5.That is, the change owing to utilizing a switching mechanism 65 to carry out the upset of substrate 5 and the limit along throughput direction, therefore the line length in laminating apparatus 60 can not be oppressed.
In addition, overturn utilizing switching mechanism 65 pairs of substrates 5 and after the change on the limit of throughput direction, niproll 16,16a can be utilized to substrate 5 from lower surface laminating polarizing coating.Thus, by laminating apparatus 60 pairs of substrates 5 two sides all from lower surface laminating polarizing coating, rectification environment can not be hindered.
In Figure 14, the throughput direction of first substrate conveying mechanism 61 and second substrate conveying mechanism 62 does not configure in a straight line, and becomes adjacent structure.When comparing the substrate 5 of Figure 14 (a) and the substrate 5 of Figure 14 (d), the straight line after the multiple mid points between summit in correspondence with each other connect is the angle of 45 ° relative to the throughput direction of substrate 5 in first substrate conveying mechanism 61.So, the throughput direction of the throughput direction of first substrate conveying mechanism 61 and the substrate 5 of second substrate conveying mechanism 62, towards same direction, although namely parallel, is not on the same line.In addition, the configuration of the substrate 5 of Figure 14 (d) is an example, need not strictly make this configuration.
