In the following description, well-known functions or constructions are not described in detail to avoid obscuring the subject matter of the present invention.

1 is a conceptual diagram briefly showing the overall configuration of a transparent electrode film manufacturing apparatus according to an embodiment of the present invention.

Referring to FIG. 1, the apparatus 1 for manufacturing a transparent electrode film 1 includes at least one unwinding roll 10 that releases and supplies a film substrate as a material, and a transparent electrode manufactured through a whole process. At least one winding roll (ie, winding roll) 20 for wrapping and storing the film. The unwinding roll 10 and the unwinding roll 20 may be driven at the same rotational speed by the respective driving motors M. For this purpose, it is preferable that the unwinding roll 10 and the unwinding roll 20 are synchronously controlled from the controller 500 to be described later.

In particular, the transparent electrode film manufacturing apparatus according to an embodiment of the present invention, the hot embossing portion 100 to form a grid-shaped pattern groove in a hot embossing method with respect to the film substrate to be transferred in the above manner and in the formed groove A gravure printing roll coating part 200 for printing a conductive ink and a conductive material coating part 300 for coating a conductive material (that is, a conductive polymer) on the film substrate on which the printing is completed.

It may further include a control unit 500 for controlling the operation of (300). In addition, the control unit 500 may control the operation of the driving motor M connected to the unwinding roll 10 and the unwinding roll 20 mentioned above as a basic configuration of the transparent electrode film manufacturing apparatus. Of course, the rotation direction can be controlled synchronously.

In addition, as can be seen through FIG. 1, after the coating of the conductive material is completed through the conductive material coating part 300, the drying part 400 may be additionally configured to heat and dry it to a set temperature.

Hereinafter, the main detailed configuration of the transparent electrode film manufacturing apparatus according to an embodiment of the present invention shown in FIG. 1 will be described in detail with reference to FIGS. 2 to 7.

 The hot embossing part 100 is an apparatus which forms the grid | lattice-shaped pattern groove on the surface through the hot embossing process with respect to the film base material unwound by the unwinding roll 10 and conveyed at the set speed. Specifically, the hot embossing unit 100 corresponds to one of a roll to roll apparatus for a hot embossing process, and performs an embossing process of a polymer material using a heating roll, a pattern roll, or a cooling roll. It is a device that can be realized continuously.

2 is an enlarged view illustrating a schematic shape of a hot embossing part 100 that is a part of a transparent electrode film manufacturing apparatus according to an exemplary embodiment of the present invention.

The illustrated hot embossing part 100 is a heating roll that is rotated vertically above the conveying roll (hereinafter referred to as a 'first conveying roll') R disposed under the conveying direction of the film base material S (for convenience of description). 110). In addition, an outer circumferential protrusion 111 having a concave-convex surface is formed on the outer circumferential surface of the heating roll 110 in a size and a shape corresponding to the lattice pattern groove S ′.

As shown in the drawing, the heating roll 110 may further include heating means for heating the outer circumferential surface evenly, although not separately illustrated, to form a grid-shaped pattern groove having a uniform depth on one surface of the film substrate S. Can be. And it should be able to be sufficiently pressurized in the process of forming the grid pattern groove, it is preferable to have a suitable mechanical strength. Conditions such as the rotational speed, the heating state of the heating roll 110 may be actively adjusted by the control signal (C1) applied by the control unit (reference numeral 500 of FIG. 1) described above.

Using such a hot embossing part 100, a grid-shaped pattern groove S 'of a size and shape desired by an operator is formed on one surface of the film substrate S that is transported via it. Here, although not shown through a separate drawing, the thickness, width, etc. of the outer periphery protrusion 111 of the heating roll 110 can be changed to another shape according to the operator's selection, in this manner The mesh electrode shape can be easily manufactured to suit the required shape.

The gravure printing roll coating part 200 is a device that fills and prints a conductive ink into a grid pattern groove formed on one surface of a film substrate through the hot embossing part 100 as described above, and processes a conductive mesh pattern called a mesh electrode. Corresponds to the device. In particular, in the present embodiment, a device commonly referred to as a microgravure printing roll coater (ie, a μ-gravure roll coater) may be used, and a conductive paste material such as silver paste is used as the conductive ink. However, this is only a preferable example, and the present invention does not need to be limited to the use of this specific material, and any material that can be used as a conventionally known conductive ink may be appropriately changed according to the operator's choice.

Figure 3 is an enlarged view showing a schematic shape of the gravure printing roll coating part of the transparent electrode film manufacturing apparatus according to an embodiment of the present invention.

The illustrated gravure printing roll coating part 200 is formed of a transfer roll (hereinafter, referred to as a 'second transfer roll' different from the 'first transfer roll' for convenience of description) hereinafter disposed below the transfer direction of the film substrate. And a coating roll 210 which rotates in the vertical direction and applies the conductive ink to the plane of the film substrate S (more specifically, the previously formed lattice pattern groove) and embeds the conductive ink.

The coating roll 210 is configured to rotate in a set direction and speed by receiving the control signal (C2) from the above-described control unit (reference numeral 500 of FIG. 1), as can be seen through the drawing, the film substrate to transfer (S) ) Is preferably arranged to rotate at a predetermined interval. Here, the predetermined interval means the interval secured so that the conductive ink I buried in the outer circumferential surface of the coating roll 210 is transferred to one surface of the film substrate S so that printing can be performed between the components.

An ink supply unit 290 is formed in front of the coating roll 210 in the rotational direction. In particular, the injection hole of the ink supply unit 290 is disposed in close proximity to the outer circumferential surface of the coating roll 210 and is provided in a form capable of evenly supplying the conductive ink toward the outer circumferential surface of the coating roll 210.

Meanwhile, the gravure printing roll coating part 200 further includes a plurality of blades 250 and 270 in consideration of more precise and efficient printing performance in addition to the coating roll 210 and the ink supply part 290 described above. . In the case of the blade shown in Figure 3, it is arranged in only two embodiments, but this is only a preferred exemplary form, the present invention is not limited thereto.

First, the blades (hereinafter referred to as 'first blade' for convenience of explanation) 250 disposed at intervals toward the outer circumferential surface of the coating roll 210 may uniform the amount of conductive ink supplied to the outer circumferential surface of the coating roll 210. It is in charge of adjusting the function.

That is, the conductive ink I applied to the outer circumferential surface of the coating roll 210 should be formed in an even distribution through the entire outer circumferential surface of the coating roll 210. This is because the thickness of the conductive ink applied to the film substrate S is also related. However, since a larger amount of conductive ink I may be applied in some sections when the actual device is driven, the conductive ink I supplied to the coating roll 210 by using the first blade 250 may be applied. Make the amount even.

In addition, on one surface of the film substrate S to which the conductive ink I is applied by the coating roll 210, the conductive ink remaining in the remaining region except for the lattice pattern grooves (S ′ in FIG. 2) is removed. Work is required. A configuration in charge of such a task includes another type of blade (hereinafter referred to as 'second blade' for convenience of description) 270. The second blade 270 is placed in the vertical direction on the isotropic path of the film substrate S on which the conductive ink is applied in a plane. In particular, as the tip portion has a structure facing toward the film substrate S, the conductive ink remaining in the remaining region except for the lattice pattern grooves (S 'in FIG. 2) is removed. As a result, the conductive ink is printed only in the lattice pattern groove of the film base material S, and this serves as the mesh electrode AG of the transparent electrode film.

As illustrated in FIG. 1, the conductive material coating part 300 is a device for coating a conductive material onto the surface of the film substrate on which the conductive ink is printed.

4 is a view illustrating a schematic shape of a conductive material coating part which is a part of a transparent electrode film manufacturing apparatus according to an embodiment of the present invention. The conductive material in the present embodiment may use a conductive polymer.

Referring to FIG. 4, the conductive material coating part 300 shown in FIG. 4 is formed on the upper portion of the transfer roll (hereinafter referred to as 'the third transfer roll') R disposed below the transfer direction of the film substrate. It is arranged opposite to S).

The conductive material coating unit 300 receives the control signal C3 of the above-described control unit 500 to spray the conductive material particles (ie, CPD) to one surface of the film substrate S to form the conductive coating layer CP. . At this time, as a characteristic configuration of the present invention, the conductive material coating unit 300 is a device for coating the conductive material in a manner that is applied simultaneously with the air injection, that is, electro-static spray deposition (ESD).

In particular, the conductive material is coated by simultaneously applying an air spray and an electrospinning method by using the conductive material coating part 300 from the time point at which the conductive material starts to be coated to the time when the last coating is left. This coating method can significantly shorten the time required for the process by several minutes.

Subsequently, at the time of performing the last coating, the conductive material is coated using only the electrospinning method by using the conductive material coating part 300. This coating method has a disadvantage that the time required for the process is relatively slow compared to the previous method, but improves the surface roughness characteristics of the final mass produced transparent electrode film up to several nanometers (for example, 2 to 3 nm).

In other words, the time required to coat the conductive material through the simultaneous application of air spraying and electrospinning can be shortened, and the product quality of the final mass produced transparent electrode film can be coated only by the electrospinning method. You can improve to the level.

Detailed configuration and effect of the conductive material coating unit 300 that provides such a function will be described in detail with reference to FIGS. 5 and 6.

First, FIG. 5 is a view illustrating a conductive material coating part operating in a method of simultaneously applying air injection and electrospinning in a transparent electrode film manufacturing apparatus according to an embodiment of the present invention.

As shown, the conductive material coating unit 300 is a nozzle 310 of the type capable of discharging the conductive material particles (CPD) in a manner in which air injection and electrospinning are applied simultaneously, and supplying air at a set pressure The air supply unit 360 and a power supply unit 370 for forming an electrospinning condition by applying voltages having opposite polarities (that is, + and −) toward the nozzle 310 and the ground main body 350. do.

In particular, the nozzle 310 simultaneously supplies the air supplied from the air supply unit 360 and the conductive material (ie, the conductive polymer) supplied through the upper supply unit 311 onto the surface of the film substrate S on which the conductive ink is printed. Spray.

To this end, a plurality of hollows partitioned from each other are provided on the nozzle end 315, and specific shapes thereof may be confirmed through FIG. 7.

That is, the inside of the nozzle end 315 illustrated in FIG. 7 includes a first hollow flow path 315a provided along the center and discharging conductive polymer particles in an electrospinning manner. In addition, there is further provided a second hollow flow path 315b which forms an isolated flow path on the circumferential side of the first hollow flow path 315a and injects air introduced into the nozzle.

Referring to FIG. 5 again, the air supply unit 360 and the power supply unit 370 will be described.

The air supply unit 360 is a device provided to supply compressed air through the side surface of the nozzle 310 as described above. Since it can be configured using, a detailed description of the corresponding portion will be omitted. The air supply unit 360 may receive an additional control signal C3 ′ from the control unit 500 described in FIG. 1 to turn on / off the air supply or adjust the supply pressure of the air. Meanwhile, a separate air flow passage 313 may be further provided at a portion penetrating the side surface of the nozzle 310, and the air flow passage 313 may be a second hollow flow passage through which air is injected (reference numeral 315b of FIG. 7). It has a structure in communication with.

On the other hand, the power supply unit 370 is electrically connected toward the nozzle 310 side and the ground main body 350 provided under the film base material S, in which case the nozzle 310 and the ground main body 350 are respectively connected. Voltages with opposite polarities are applied. Accordingly, the conductive material is discharged to the upper portion of the film substrate S in an electrospinning manner to form a predetermined conductive coating layer.

The control signal C3 'is applied to the air supply unit 360 from the above-described control unit (reference numeral 500 in FIG. 1), and the control signal C3 " is also popular as the power supply unit 370.

In the case of FIG. 5, the control signal C3 ′ applied to the air supply unit 360 corresponds to an ON command, and air of a predetermined pressure is supplied toward the inside of the nozzle 310. Meanwhile, the control signal C3 ″ applied to the power supply unit 370 also corresponds to the ON command, and voltages having opposite polarities are set to the nozzle 310 and the ground main body 350, respectively. Accordingly, in the form in which the air jet and the electrospinning are simultaneously applied, the conductive material is sprayed onto the film substrate S to form a conductive coating layer.

In this case, the size of the particles of the conductive material to be sprayed (ie, D1) has a larger diameter compared to the size of the particles of the conductive material to be sprayed only by the electrospinning manner, which will be described with reference to FIG. 6 (ie, D2). On the other hand, in the case of FIG. 5, the spray angle range (a1 °) of the particles of the conductive material to be sprayed is smaller than the spray angle range (a2 °) of the particles of the conductive material to be sprayed only by the electrospinning method to be described with reference to FIG. 6. Has an angular range. Here, in the case of different methods, that is, a method in which air injection and electrospinning are simultaneously applied, and a method in which only electrospinning is applied, the differentiated exemplary shapes for the angular ranges (ie, a1 ° and a2 °) from which the conductive material is sprayed are shown in FIG. 7. You can check in detail.

In FIG. 6, the control signal C3 ′ applied to the air supply unit 360 corresponds to an OFF command, and the flow of air supplied toward the inside of the nozzle 310 is interrupted. In addition, only the control signal C3 ″ applied to the power supply unit 370 continuously corresponds to the ON command, and the conductive material is discharged only through the nozzle 310 in the electrospinning manner, so that the conductive finish coating layer is formed on the film substrate S. Will form. According to this action, the surface roughness characteristics of the final mass produced transparent electrode film can be improved to several nanometers.

8 is a process diagram sequentially illustrating a shape in which the transparent electrode film is manufactured using the apparatus for manufacturing a transparent electrode film according to an embodiment of the present invention.

First, referring to FIG. 8A, a lattice-shaped pattern groove S ′ is formed on one surface of the film substrate S prepared according to the action of the hot embossing part (reference numeral 100 of FIG. 1). In this case, the usable film base material S may be a flexible material, and as a specific example, a flexible plastic film may be used. In addition, although one surface of the film substrate (S) shown is shown a uniform square irregular pattern of a certain form, the present invention does not necessarily need to be limited to the shape of such a product.

Referring to (b) of Figure 8, in accordance with the action of the above-described gravure printing roll coating portion (200 in FIG. 1), the conductive material in the form of ink into the lattice pattern groove provided on the surface of the film substrate (S) The mesh electrode AG is printed. In this case, silver paste or the like may be used as a specific example of the conductive material.

In the case of FIGS. 8C and 8D, the conductive coating layer CP is formed in such a manner that air injection and electrospinning are applied at the same time by the action of the aforementioned conductive material coating part (300). Next, in the final coating process, the conductive polymer is coated only by electrospinning to further form a conductive finish coating layer CP ′ having excellent surface roughness. As a result, the surface roughness of the finally produced transparent electrode film is improved to several nanometers (eg, 2 to 3 nm).

As described above, according to the transparent electrode film manufacturing apparatus according to an embodiment of the present invention, it is possible to quickly process the grid-shaped pattern groove having various thickness and width size on one surface of the film substrate through the hot embossing portion. This helps to improve product productivity and manufacture a variety of products.

In addition, a conductive material such as silver paste may be embedded in the grid pattern groove provided in advance using the gravure printing roll coating to print the same. This manufacturing method helps to continuously manufacture the transparent electrode film, and is effective in mass-producing a large area of the transparent electrode film.

The gravure printing method is used to coat the conductive polymer on top of the film substrate on which the conductive material is printed in a lattice shape. Most of the operations of forming the conductive coating layer are performed by applying air spraying and electrospinning methods simultaneously. On the other hand, the conductive coating layer is formed by electrospinning only during the finishing coating operation. As a result, the overall mass production speed of the transparent electrode film can be improved quickly, and the surface roughness quality of the final mass produced transparent electrode film can be improved to several nanometers (eg, 2 to 3 nm).

It has been described above with respect to the transparent electrode film manufacturing apparatus according to an embodiment of the present invention. It is to be understood that the above-described embodiments are to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, All changes or modifications that come within the scope of the equivalent concept are to be construed as being included within the scope of the present invention.
