Description

  The present invention relates to a thin film forming apparatus and a thin film forming method. The present invention also relates to a printing medium on which a printing material is printed by the thin film forming method.

  As a method for forming a thin film such as an alignment film or a color filter on a glass substrate used for a liquid crystal display element, a printing method using a flexographic printing apparatus is known. In this printing method, as shown in FIG. 6, the liquid thin film forming solution 5 is appropriately applied from the upper part of the anilox roll 10. Then, the surface of the thin film forming solution 5 dropped onto the surface of the anilox roll 10 is flattened by the doctor blade 20. Next, the flattened thin film forming solution 5 is transferred from the anilox roll 10 to the printing plate 31 on the plate cylinder 30. Thereafter, the thin film forming solution 5 transferred to the printing plate 31 is transferred onto the upper surface of the glass substrate 2a and applied.

  Hereinafter, an example of an embodiment to which the present invention is applied will be described. It goes without saying that other embodiments may also belong to the category of the present invention as long as they match the gist of the present invention. Moreover, the size and ratio of each member in the following drawings are for convenience of explanation, and are different from actual ones.

[Embodiment 1]
FIGS. 1A and 1B and FIGS. 2A and 2B are schematic explanatory views for explaining an example of a thin film forming apparatus and a thin film forming method according to the first embodiment. The left-right direction in the figure is the X-axis direction, and the up-down direction is the Z-axis direction. A direction perpendicular to the paper surface is defined as a Y-axis direction. 3A is a schematic perspective view of the anilox roll, and FIG. 3B is a cross-sectional view taken along the line IIIb-IIIb in FIG. 3A. FIG. 3C is a partially enlarged schematic view of the A1 region (first area 11) of FIG. 3B, and FIG. 3D is a view of the A2 region (second area 12) of FIG. 3B. The partial expansion schematic diagram is shown.

  The thin film forming apparatus 1 according to the first embodiment is an apparatus for performing flexographic printing. Of course, the present invention can be suitably applied also to relief printing other than flexographic printing. As shown in FIG. 1, the thin film forming apparatus 1 includes an anilox roll 10 as an intaglio roll, a doctor blade 20 as a flattening means, a plate cylinder 30 as a printing roll, a relief printing plate 31, a printing stage 40, and an ink supply unit 50. Etc.

  The anilox roll 10 is a cylindrical roll (see FIG. 3A) in which mesh-like ink cells (engraving pattern) 15 (see FIG. 3C) are formed on the outer peripheral surface thereof, and is in the Y-axis direction. It is attached to a housing (not shown) so as to be rotatable with respect to the rotating shaft 18. The anilox roll 10 according to the first embodiment rotates clockwise in FIG. The ink cell 15 formed on the outer peripheral surface of the anilox roll 10 is divided into two areas of a first area 11 and a second area 12 having different patterns. Details will be described later. An ink supply unit 50 is disposed on the anilox roll 10.

  The ink supply unit 50 includes a dispenser nozzle, a solution tank, and the like, and plays a role of supplying the thin film forming solution 5 to the anilox roll 10. For example, it is provided along the upper surface of the anilox roll 10 so as to reciprocate in the Y-axis direction. A thin film forming solution 5 such as ink is dropped on the surface of the anilox roll 10 by the reciprocating movement of the ink supply unit 50. Thereby, the thin film forming solution 5 adheres to the surface of the anilox roll 10. The thin film forming solution 5 is, for example, a resin solution or a resin precursor solution for forming an alignment film, a color filter layer, a black matrix layer, or the like applied to a liquid crystal display device or the like. The thin film forming solution 5 may be so-called ink and is not particularly limited.

  The doctor blade 20 is located downstream in the rotational direction from the ink supply unit 50 and upstream in the rotational direction from the position where the anilox roll 10 and the printing plate 31 are in contact with each other. The role of the doctor blade 20 is to flatten the surface of the thin film forming solution 5 on the surface of the anilox roll 10 supplied from the ink supply unit 50. By bringing the doctor blade 20 and the anilox roll 10 into contact with each other at a predetermined contact pressure, the surface of the thin film forming solution 5 is flattened to form a film having a predetermined thickness on the anilox roll 10. In addition, what is necessary is just to be able to planarize the thin film formation solution 5 surface supplied on the anilox roll 10, and it may replace with the doctor blade 20 and may use other planarization means, such as a doctor roll.

  The plate cylinder 30 is a cylindrical roll having a printing plate 31 having a transfer pattern formed on the outer peripheral surface thereof, and is attached to a casing (not shown) so as to be rotatable with respect to a rotation axis 38 in the Y-axis direction. It has been. The plate cylinder 30 according to the first embodiment rotates counterclockwise in FIG.

  The printing plate 31 is a flexographic plate having convex portions and rotates integrally with the plate cylinder 30. The printing plate 31 and the anilox roll 10 are disposed so as to come into contact with each other with a predetermined pressure.

  The printing stage 40 is a mounting table for the substrate 2 and is configured to be freely movable in the X, Y, and Z axis directions. Further, it may be configured to be rotatable with respect to the Z axis. At a position where the printing medium 2 is placed on the printing stage 40, means for fixing the printing medium 2 such as vacuum suction is provided. The printing stage 40 conveys the printing medium 2 to a position in contact with the printing plate 31 in accordance with the rotation timing of the printing plate 31. As a result, the thin film forming solution 5 carried on the printing plate 31 is transferred to the printing medium 2. By allowing the printing stage 40 to move in the Z-axis direction, the printing medium 2 and the printing plate 31 can be moved according to the thickness and type of the printing medium 2 and the thickness of the printing medium 3 formed on the printing medium 2. It can adjust so that it may become an appropriate contact pressure.

  Examples of the substrate 2 include a glass substrate, a plastic substrate such as polycarbonate, and a sheet such as paper. The printed material 3 (see FIGS. 2A and 2B) which is a thin film fixed to the printing material 2 may be a so-called solid film or a pattern film such as a color filter layer or a black matrix. Good. Moreover, a character pattern etc. may be sufficient. Since the convex pattern of the printing plate 31 is transferred to the substrate 3, the printing plate 31 having a desired convex pattern may be used.

  The outer peripheral surface of the anilox roll 10 is divided into two regions, a first area 11 and a second area 12, as shown in FIG. The first area 11 and the second area 12 are divided substantially parallel to the long axis direction D1 of the anilox roll 10. A first shape pattern 16 is formed in the first area 11, and a second shape pattern 17 is formed in the second area 12. By changing the pattern shape, the film thickness of the substrate 3 can be changed.

  As shown in FIG. 3C, the first shape pattern 16 has a large number of recessed ink cells 15 formed therein. Similarly, as shown in FIG. 3D, the second shape pattern 17 has a large number of recessed ink cells 15 formed therein. The first shape pattern 16 and the second shape pattern 17 have different depths of the recesses. In the first embodiment, the depth of the second shape pattern 17 is 2 h with respect to the depth h of the first shape pattern 16. The shape and size in plan view are the same. Therefore, the second area 12 can carry more thin film forming solution 5 than the first area 11.

  The first area 11 is, for example, a region with a target film thickness of approximately 80 nm (800 mm), and the second area 12 is, for example, a region with a target film thickness of approximately 200 nm (2000 mm). As described above, the concentration of the thin film forming solution 5, the contact pressure between the doctor blade 20 and the anilox roll 10, the contact pressure between the anilox roll 10 and the plate cylinder 30, or the contact pressure between the printing plate 30 and the printing medium 2 are determined. It goes without saying that a method of adjusting the target film thickness can be used together by a method of adjusting, a method of setting the anilox roll 10 and the plate cylinder 30 at different peripheral speeds, or the like.

  On the printing plate 31, the shape pattern of either the first area 11 or the second area 12 of the anilox roll 10 is transferred. As a result, the printing material 3 of the thin film forming solution 5 carried on either the first area 11 or the second area 12 can be formed on the printing material 2.

  The anilox roll 10 has a printing origin serving as a reference for the rotational position in each of the first area 11 and the second area 12. When one of the first area 11 and the second area 12 is selected, the printing origin is switched, and the rotational position of the anilox roll 10 and the printing plate 31 is adjusted by the rotational position control unit.

  The length in the rotation direction of the first area 11 and the second area 12 transferred from the anilox roll 10 is the X formed on the substrate 2 when the anilox roll 10 and the plate cylinder 30 are rotated at a constant speed. It is set to be not less than the length L1 of the substrate 3 in the axial direction. Actually, the circumferential length is determined in consideration of the rotation timing adjustment accuracy of the anilox roll 10 and the plate cylinder 30 and the like.

  Next, the operation of the thin film forming apparatus 1 according to the first embodiment will be described with reference to FIGS. First, it is determined which of the first area 11 and the second area 12 of the anilox roll 10 is to be transferred to the printing medium 2. Here, an example in which the first shape pattern 16 formed in the first area 11 is transferred to the printing plate 31 will be described.

  FIG. 6 is a block diagram showing a schematic configuration of the position adjusting mechanism. As shown in the figure, the print adjustment mechanism 60 includes a processing unit 61, a selection area information unit 62, a thin film formation condition information unit 63, a printing origin switching unit 64, a storage unit 65, a rotation position control unit 66, and the like.

  In the position adjustment mechanism 60, the transfer of the first area 11 of the anilox roll 10 is transmitted from the selection area information unit 62 to the processing unit 61. Further, thin film formation conditions other than the selected area information (for example, the viscosity of the thin film formation solution, the type information of the solution, etc.) are transmitted from the thin film formation condition information unit 63 to the processing unit 61. Further, the print origin switching unit 64 sets the print origin position of the first area 11 to be a predetermined position.

  The processing unit 61 of the position adjustment mechanism 60 transmits information from the selection area information unit 62 and the thin film formation condition information unit 63 to the storage unit 65 and reads out the optimum anilox roll 10 and plate cylinder 30 rotation conditions. The storage unit 65 stores in advance optimum rotation conditions for the anilox roll and the plate cylinder 30 according to each condition. Then, the information is transmitted to the processing unit 61. Based on this information, the rotational position controller 66 rotates the anilox roll 10 and the plate cylinder 30 at a predetermined speed while adjusting the mutual rotational position.

  When the thin film forming solution 5 carried in the area of the second area 12 is to be transferred to the printing medium 2, it is reset and the transfer of the second area 12 is transmitted from the selection area information section 62 to the processing section 61. . Then, the position adjustment mechanism 60 is operated in the same procedure as described above. By switching the reference printing origin, the printing plate 31 and the transfer area can be easily switched. As a result, by switching the printing origin of the anilox roll 10, it is possible to easily obtain the substrate 3 having a significantly different film thickness.

  In the first embodiment, the diameter and peripheral speed of each roll are set so that the rotational speeds of the surface of the anilox roll 10 and the surface of the plate cylinder 30 are the same. Thereby, the printing plate 31 and the surface of the anilox roll are sequentially contacted without slipping, and the thin film forming solution 5 filled in the shape pattern on the outer peripheral surface of the anilox roll 10 can be transferred to the printing plate 31 satisfactorily.

  Next, as shown in FIG. 1A, the thin film forming solution 5 is dropped from the dispenser nozzle of the ink supply unit 50 onto the surface of the first area 11. Then, the surface of the thin film forming solution 5 is flattened by the doctor blade 20 located on the downstream side in the rotation direction of the anilox roll 10 with respect to the ink supply unit 50 (see FIG. 1A).

  The first area 11 carrying the thin film forming solution 5 flattened by the doctor blade 20 is then rotated while abutting against the printing plate 31 as shown in FIG. Thereby, the thin film forming solution 5 in the first area 11 of the anilox roll 10 is transferred to the printing plate 31.

  The thin film forming solution 5 transferred to the printing plate 31 is further transferred to the printing medium 2, whereby the thin film forming solution 5 is applied to the printing medium 2 (see FIG. 2A). The printing medium 2 is fixed to the printing stage 40 and is conveyed in the X-axis direction together with the printing stage 40 in conjunction with the rotation timing of the printing plate 31. Then, the printing plate 31 and the printing medium 2 come into contact with each other with a predetermined contact pressure, and the thin film forming solution 5 is transferred from the printing plate 31 to the printing medium 2.

  Thereafter, the thin film forming solution 5 transferred onto the printing medium 2 is fixed as necessary. The fixing unit is not particularly limited, and examples thereof include heating and UV light. Thereby, for example, the resin precursor is converted into a resin or the like and fixed to the printing medium 2. In this Embodiment 1, the to-be-printed material 3 was obtained by heating. The fixing process may be performed simultaneously with the transfer timing even after the transfer to the printing medium 2. In addition, after transferring the thin film forming solution 5 to the printing medium 2, a solvent heating drying step and the like may be added.

  Conventionally, when trying to obtain a substrate 3 having a significantly different film thickness, it has been necessary to replace the anilox roll 10 itself. However, according to this method, several hours are required for the replacement work and the confirmation work after the replacement. According to the first embodiment, the pattern area having two different shapes of the first area 11 and the second area 12 having different pattern shapes is provided on the outer peripheral surface of the anilox roll 10, and only one of the areas is provided on the printing medium 2. Therefore, the two substrates 3 having large film thickness fluctuations can be obtained without replacing the anilox roll 10, that is, while maintaining high productivity.

  Furthermore, a method for adjusting the concentration of the thin film forming solution 5, a method for adjusting the contact pressure between the doctor blade 20 and the anilox roll 10, a method for adjusting the contact pressure between the anilox roll 10 and the plate cylinder 30, and the printing plate 31 and the printing target By using a method for adjusting the contact pressure (printing pressure) with the body 2 and a method such as temperature adjustment, the film thickness can be adjusted for each area. Therefore, the film thickness width that can be handled can be greatly increased.

  In horizontal electric field type (IPS type, etc.) liquid crystal display panels, the film thickness is significantly increased compared to conventional liquid crystal display panels (eg, TN type liquid crystal display panels) in order to improve image sticking characteristics and contrast. It is requested to do. According to the first embodiment, for example, the first area 11 is used to form an alignment film of a TN liquid crystal display panel, and the second area 12 is formed of an alignment film of an IPS liquid crystal display panel. For example, parts can be shared. Therefore, manufacturing efficiency can be increased.

  The first shape pattern 16 and the second shape pattern 17 are configured with different patterns so that thin films with different film thicknesses can be formed, but the depth of the ink cell 15 is changed as in the first embodiment. It is not limited to the mode to do. For example, the first shape pattern 16 may be as shown in FIG. 5A or 5B instead of the shape shown in FIG. According to the example of FIG. 5A, the first shape pattern 16x and the second shape pattern 17 have the same ink cell 15 depth, and the first shape pattern 16x is the first shape pattern 16 shown in FIG. The arrangement density is set to ½.

  Further, according to the example of FIG. 5B, the arrangement density and the ink cell depth of the first shape pattern 16y and the second shape pattern 17 are the same, and the shape of the pattern of the first shape pattern 16y is shown in a cross-sectional view. It is designed to be V-shaped. As the pattern shape, various shapes such as a V shape and a U shape can be used. Further, the shape in plan view may be changed. For example, the rectangular ink cell may be a circular ink cell or a polygonal ink cell. Furthermore, the pattern shape may be the same and the pattern size may be changed. The arrangement density, ink cell depth, ink cell shape, ink cell size, and the like can also be applied in combination. The first pattern shape 16 in each area may be the same pattern when viewed macroscopically, and is not limited to a single ink cell depth or shape. For example, in a plan view, a rectangular pattern and a circular pattern may be mixed. The same applies to the second area 12.

  Moreover, although the example which divided | segmented the area of the outer peripheral surface of the anilox roll 10 into two was described in this Embodiment 1, it is not limited to this, You may divide | segment into three or more. By setting the number to three or more, the width of the film thickness that can be formed by one anilox roll can be further increased.

  In the first embodiment, the example in which the surface of the anilox roll 10 and the surface of the plate cylinder 30 are constant speed has been described. However, the present invention is not limited to this, and the speed may be changed as appropriate. Needless to say. For example, by setting the peripheral speed on the surface of the anilox roll 10 to be faster than the peripheral speed on the surface of the plate cylinder 30, the length in the rotation direction of the area transferred to the printing plate 31 can be shortened. . As a result, the diameter of the anilox roll 10 can be reduced as compared with the case where the diameter is set to be constant.

  Further, in the first embodiment, an example in which there is one printing plate 31 attached to the plate cylinder 30 is described. However, the printing plate 30 corresponds to each of the first area 11 and the second area 12. Two 31 may be attached. Then, the thin film forming solution 5 is supplied from the ink supply unit 50 to the first area 11 and the second area 12, and the thin film forming solution 5 in the first area 11 and the second area 12 is alternately transferred to the printing medium 2. And you may make it obtain the to-be-printed material 3 of a different film thickness alternately. Thereby, it becomes possible to raise manufacturing efficiency more. For example, the alignment film of the TN type liquid crystal display panel and the alignment film of the IPS type liquid crystal display panel may be alternately conveyed to form a film continuously.

  Further, the position adjusting mechanism 60 is an example, and various modes can be used without departing from the spirit of the present invention. For example, instead of the origin position as described above, a mark is provided in each area of the anilox roll 10 and the plate cylinder 30, and the rotation position is detected by a CCD camera, and the rotation is performed by a control device (not shown). The position may be controlled.

  The anilox roll 10a includes a position adjusting mechanism that adjusts an area where the ink supply unit 50 supplies the thin film forming solution to either the first area 11a or the second area 12a. The ink supply unit 50 is configured to reciprocate in the Y-axis direction along the upper surface of the anilox roll 10a, and includes a mechanism for supplying the thin film forming solution 5 only to a designated area. Thereby, it can set so that a thin film formation solution may be supplied only to a desired area.

  On the printing plate 31, the shape pattern of either the first area 11a or the second area 12a of the anilox roll 10a is transferred. Then, the printing stage 40 is adjusted in the Y-axis direction so that the printing plate 31 carrying the thin film forming solution 5 and the printing medium 2 are transferred in contact with each other. Thereby, the to-be-printed body 3 of the thin film formation solution 5 carried by either one of the 1st area 11a or the 2nd area 12a can be formed in the to-be-printed body 2. FIG. Of course, it is also possible to simultaneously transfer the thin film forming solution to the first area 11a and the second area 12a, place the two print media 2 on the printing stage 40 and transport them, and simultaneously perform the printing process.

  According to the method according to the second embodiment, the same effect as in the first embodiment can be obtained. Moreover, increasing the diameter of the anilox roll 10a can be suppressed.

  The method for dividing the area of the anilox roll is not limited to the above embodiment, and it is only necessary that the area having at least two different ink cells in the outer peripheral surface is formed. The combination of Embodiments 1 and 2 can also be suitably applied.
