More specifically, Fig. 1A schematically shows a printing roll according to the prior art.

Referring to FIG. 1A, a printing roll 50 according to the prior art includes a blanket 55 provided on the outer circumferential surface thereof and a light irradiation device 58 provided therein. The printing roll 50 has a rotary shaft 51 disposed at the center thereof and is rotationally driven as the rotary shaft 51 is rotated. The blanket 55 is arranged so as to surround the outer circumferential surface of the printing roll 50, and a printing pattern 55P to be formed is formed on the surface thereof. The blanket 55 may be made of any one of silicone rubber, polyurethane, and photocurable acrylate.

The light irradiation device 58 is installed inside the printing roll 50 and selectively irradiates the light along the rotation direction of the printing roll 50. The light irradiating device 58 includes a light source 57 and a reflector 59 provided on the outer periphery of the light source 57 and shielding and reflecting the light emitted from the light source 57. Here, the light source 57 may use ultraviolet light having a wavelength of 300 to 500 mu m. The reflection plate 59 may be formed in an arc shape expanded at an angle of 1 to 179 degrees, or may be made of any one of stainless steel and metal.

On the other hand, as the light irradiation device 58 is provided in the printing roll 50, a transparent quartz material can be used so that light irradiation from the light irradiation device 58 is smooth.

1B to 1E are views showing a method of forming a print pattern using a printing roll according to the related art.

Referring to FIGS. 1B to 1E, in the prior art, an etching target layer 103 is formed on a substrate 101, as shown in FIG. 1B. Thereafter, a mask film 105 is formed on the substrate 101 having the etching target layer 103 in order. Thereafter, a uniform pressure is applied to the printing roll 50 so that the printing roll 50 shown in Fig. 1A is brought into contact with the substrate 101 having the mask film 105. Then,

Thereafter, the printing roll 50 is rotated in a predetermined direction on the substrate 101 having the mask film 105, as shown in Figs. 1C and 1D. In this case, a spare mask film pattern 105P1 filling the print pattern 55P of the printing roll 50 is formed while the printing roll 50 is rotated. This spare mask film pattern 105P1 corresponds to the mask film remaining in the print patterns 55P.

Thereafter, the light source 57 is irradiated through the light irradiation device 58 to cure the spare mask film pattern 105P1 filling the print patterns 55P. At this time, the printing process and the curing process can be performed at the same time, and in some cases, the curing process may be performed after the printing process. As a result, a mask pattern 105P2 is formed on the etching target layer 103 of the substrate 101. [

On the other hand, the light can be reflected at the surface of the spare mask film pattern 105P1 while the light is irradiated to the spare mask film pattern 105P1 filling the print pattern 55P. At this time, the reflection plate 59 serves to condense the reflected light reflected from the surface of the spare mask film pattern 105P1, thereby greatly increasing the amount of light irradiated to the spare mask film pattern 105P1. The reflector 59 is preferably made to have an angular range of 1 to 179 degrees so that the necessary amount of light can be selectively used.

As described above, in the conventional technique, the printing roll 50 is rotated on the mask film 105 on the substrate 101 to form the spare mask film pattern 105P1 filling the printing pattern 55P of the blanket 55, The preliminary mask film pattern 105P1 is selectively cured to form a mask pattern 105P2. Accordingly, in the prior art, the printing process and the curing process are simultaneously performed, thereby achieving the advantage that the total number of processes and the process time are reduced.

However, since the blanket 55 in which the pattern is to be formed is made of an elastic material such as silicone rubber, polyurethane, photocurable acrylate or the like in the printing roll 50 according to the conventional art described above, However, there is a problem that the ink is pressed and spread due to elasticity during pattern transfer, which makes it difficult to accurately transfer the pattern.

One of the measures for solving the problem of the blanket 55 used in the printing roll 50 according to the above-mentioned prior art is to apply a specific coating liquid (for example, a photoresist PR ) Solution) in a spraying manner is used.

1F is a view schematically showing a printing roll manufacturing apparatus according to an embodiment of the prior art.

Referring to FIG. 1F, a printing roll manufacturing apparatus 100 according to an embodiment of the prior art is disposed in parallel to and spaced apart from a roll 50, and a coating film 54 A spray nozzle 102 for spraying the coating liquid to form a coating liquid; A moving member 104 for horizontally moving the spray nozzle 102; A rotary member 106 for rotating the rotary shaft 51 of the roll 50; A drying device (160) for drying the coating film (54) of the roll (50); A conveying member (150) for conveying the roll (50) to the drying apparatus (160); A curing device (170) for curing the coating film (54) of the roll (50); And a second conveying member (not shown) for conveying the roll 50 to the curing device 170. Here, the movable member 104 may be embodied as a conventional linear motor, for example, and the rotary member 106 may be embodied as a rotary motor. The conveying member 150 may be a crane or a robot arm, and the second conveying member may be a conveyor or a robot arm, for example. In addition, the both rotation shafts 51 of the roll 50 can be rotated in a fixed state by chucks (not shown).

The spray nozzle 102 is moved by the moving member 104 while the rotary shaft 51 of the roll 50 is rotated by the rotary member 106 in the roll 50 The coating liquid 108 is applied while moving along the surface 52 of the coating liquid. As a result, a coating film 54 is formed on the surface 52 of the roll 50. Thereafter, the chucks on both sides of which the rotary shafts 51 of the rolls 50 are fixed are released, and the conveying device 150 picks up the rotary shafts 51 on both sides of the rolls 50 and is conveyed to the separately provided drying device 160 The drying process of the coating thin film 54 formed on the surface 52 of the roll 50 is performed. Thereafter, the dried roll 50 is transferred into the hardening device 170 by a second transfer device (not shown), and then the hardening process of the coating film 54 is performed. As a result, the production of the printing roll 50 with the coating film 54 is completed. Thereafter, a printing pattern 55P to be formed on the cured coating film 54 of the printing roll 50 in a manner according to the above-described conventional technique can be formed.

It is possible to form the coating film 54 on the surface 52 of the roll 50 very simply and also to form the coating film 54 on the surface 52 of the roll 50 It is possible to realize a precise pattern transfer on the coating film 54 formed on the substrate 54. In addition, since the pressing and spreading phenomenon of the ink does not occur even during the pattern transfer, an advantage that precise pattern transfer is possible is achieved, A problem arises.

1. In the prior art, high temperature heat generated when the drying apparatus 160 is used generates heat damage to one or more ultraviolet (UV) lamps constituting the curing apparatus 170, and the drying apparatus 160 and the curing apparatus 170 It is practically impossible to integrate them. Thus, a drying device 160 and a curing device 170, which are provided separately for the drying process and the curing process of the object such as the roll 50, are required.

2. It has been required to use a separate transfer member (i.e., a second transfer member (not shown)) for transferring an object, such as a dried roll 50, to the hardening device 170 for the curing process after the drying process.

3. Due to the above-described problems 1 and 2, there is a problem that the time required for drying and curing the object becomes long, and the size and cost of the entire equipment are increased.

4. In the prior art, a coating film 54 is formed on the surface 52 of the roll 50 and then transferred to a drying device 160 and a curing device 170 to dry and cure the coating film 54 . In this case, the coating film 54 is in a wet state until the drying and curing process is completed after the coating film 54 is formed, so that the coating film 54 flows down on the surface 52 of the roll 50 by gravity. As a result, there arises a problem that the thickness uniformity of the coating film 54 formed on the surface 52 of the roll 50 is not uniform.

5. There is also the possibility that the foreign matter may flow into or onto the coating film 54 while moving the coating film 54 in the wet state into the drying device 160 and the curing device 170.

6. There is also a possibility that scratches or the like may occur in the coating film 54 while moving the coating film 54 in the wet state into the drying device 160 and the hardening device 170.

7. Problems 4 to 6 described above cause the possibility of occurrence of defects in the object itself such as the produced printing roll 50 or in the final product (for example, the substrate to which the pattern is transferred by the printing roll 50) .

Therefore, there is a need for a new method for solving the problems of the above-described conventional techniques.

Hereinafter, the specific configuration and operation of the printing roll manufacturing apparatus according to the first embodiment of the present invention will be described in detail.

Referring again to Figs. 3a to 3d with Figs. 2a to 2d, the printing roll manufacturing apparatus 300 according to the first embodiment of the present invention includes a roll 50 having a surface 52. Fig. Both side rotary shafts 51 of the roll 50 are rotatably mounted on the chuck 355. [ A spray nozzle 102 is provided in front of the roll 50 so as to be spaced apart from the roll 50 in parallel.

Further, the rotary shaft 51 of the roll 50 can be rotated by a rotary member (not shown) while being fixed by the chuck 355. At this time, the spray nozzle 102 ejects the coating liquid onto the surface 52 of the rotating roll 50 while moving along the longitudinal direction (horizontal direction) of the roll 50 by the moving member 104, (54).

On the other hand, on the upper side of the roll 50, a temporary hardening device 310 is rotatably mounted. The tilting apparatus 310 includes a heater member 312 for hardening the coating film 54 formed on the surface 52 of the roll 50, a heater member 312 for rotating the heater member 312, 1 support member 322 and a second support member 323 that supports the first support member 322 movably in the horizontal direction. Here, the first support member 322 and the second support member 323 constitute the support member 320. [ The heater member 312 is rotatably mounted to the first support member 322 about the hinge member 324, for example, manually or by a separate rotation drive member (not shown) It is not. The heater element 312 may also be embodied as, for example, one or more ultraviolet (UV) lamps or infrared lamp (IR) lamps.

Further, an air supply member 330 may be provided at a lower portion of the second support member 323 to provide an air curtain or an air knife at a position opposite to the heater member 312, for example.

In the printing roll manufacturing apparatus 300 according to the first embodiment of the present invention as described above, both side rotation shafts 51 of the roll 50 are rotated by the rotating member (not shown) The coating liquid sprayed by the coating liquid forms a coating film 54 on the surface 52 of the roll 50.

Immediately after the coating film 54 is formed on the surface 52 of the roll 50, the roll 50 is kept in a constantly rotating state while the heater member < RTI ID = 0.0 > 312 reduces the thickness of the coating film 54. At this time, the heater member 312 maintains the orientation in which the heat generating surface 312a is oriented toward the center of the roll 50, either manually or by a separate rotation drive member (not shown). An air curtain or an air knife is formed by the air supply member 330 provided under the second support member 322 of the temporary curing device 310 so that the coating liquid sprayed from the spray nozzle 102 is supplied to the roll 50 (The counterclockwise direction as shown in Fig. 3B) of the roll 50 and the heater member 312 can be prevented from penetrating.

In addition, after the hardening of the coating film 54 by the heater member 312 is finished, the heater member 312 does not need to be used any longer, so that the hinge member 324 is rotated around the hinge member 324 And is turned counterclockwise to orient the heat generating surface 312a shown in FIG. 3B upward. The upward orientation of the heat generating surface 312a of the heater member 312 may be achieved by mounting the rotary shaft 51 of the roll 50 on the chuck 355 using a conveying member 350 such as a crane or a robot arm, The space for avoiding the interference between the heater member 312 and the roll 50 is secured when the roll 50 is transferred to the integral drying and curing apparatus 260 after the temporary hardening is completed and also when the heater member 312 is not used Foreign matter such as dust can be prevented from accumulating.

On the other hand, the first support member 322 rotatably mounted on the heater member 312 can move along the second support member 323 in the horizontal direction (i.e., the direction perpendicular to the longitudinal direction of the roll 50) (See Fig. 3d). This is for facilitating the rotation space in the upward direction of the heat generating surface 312a of the heater member 312. [ The air supply member 330 can also move in the horizontal direction (that is, in the direction perpendicular to the longitudinal direction of the roll 50) along the second support member 323 (see FIG. 3D). This is for adjusting the forming position of the air curtain or the air knife according to the diameter size of the roll 50. [ The horizontal movement of the first support member 322 and the air supply member 330 along the second support member 323 can be performed, for example, by a conventional LM guide and a linear motor.

Thereafter, the rotary shaft 51 of the roll 50 is released from the chuck 355, and then transferred into the integral drying and curing apparatus 260 by using the transferring member 350.

Hereinafter, the specific configuration and operation of the printing roll manufacturing apparatus according to the second embodiment of the present invention will be described in detail.

Referring again to Figs. 3E to 3G, with reference to Figs. 2A to 2D, a printing roll manufacturing apparatus 300 according to a second embodiment of the present invention includes a roll 50 having a surface 52. Fig. Both side rotary shafts 51 of the roll 50 are rotatably mounted on the chuck 355. [ A spray nozzle 102 is provided in front of the roll 50 so as to be spaced apart from the roll 50 in parallel.

On the other hand, on the top of the roll 50, a temporary hardening device 310 is movably provided. This temporary hardening device 310 includes a heater member 312 for hardening the coating film 54 formed on the surface 52 of the roll 50 and a heater member 312 for heating the heater member 312 to be rotatably mounted And a supporting device 320. The heater element 312 can be pivotably mounted to the support device 320 about the hinge member 324, for example, manually or by a separate rotational drive member (not shown). The heater element 312 may also be embodied as, for example, one or more ultraviolet (UV) lamps or infrared lamp (IR) lamps.

In the printing roll manufacturing apparatus 300 according to the second embodiment of the present invention as described above, the temporary curling apparatus 310 is transferred to the upper portion of the roll 50 by the second moving member 340 first.

Thereafter, a coating solution jetted by the spray nozzle 102 while the both side rotational shafts 51 of the roll 50 are rotated by a rotating member (not shown) is applied onto the surface 52 of the roll 50, ). Immediately after the above-described coating film 54 is formed on the surface 52 of the roll 50, the heater member 312 hardens the coating film 54 while the roll 50 keeps rotating. At this time, the heater member 312 maintains the orientation in which the heat generating surface 312a is oriented toward the center of the roll 50 manually or by a separate rotation drive member (not shown) (see FIG. 3F) ).

An air curtain or an air knife is formed by an air supply member (not shown) provided at a lower portion of the supporting device 320 constituting the temporary curing device 310 so that the coating liquid sprayed from the spray nozzle 102 is supplied to the roll (The counterclockwise direction as shown in FIG. 3F) of the rollers 50 and the heater member 312 can be prevented from penetrating into the rear surface of the roll 50 and the heater member 312.

Further, after the temporary thinning of the coating film 54 by the heater member 312 is finished, the heater member 312 does not need to be used any more, so that the second moving member 340 Return to the original position. At this time, the heater member 312 is rotated about the hinge member 324 so that the heat generating surface 312a is oriented upward. The upward orientation of the heat generating surface 312a can prevent foreign matter such as dust from accumulating when the heater member 312 is not used.

The use of the moving hardening device 310 described above allows the rotary shaft 51 of the roll 50 to be mounted on the chuck 355 by using a conveying member 350 such as a crane or a robot arm, The space for avoiding the interference between the temporary hardening device 310 and the roll 50 is secured when the roll 50 is transferred to the integral drying and curing device 260 after the drying is completed.

On the other hand, the air supply member (not shown) can move in the horizontal direction (i.e., the direction perpendicular to the longitudinal direction of the roll 50) along the support device 320 in the manner shown and described in Fig. 3D. This is for adjusting the forming position of the air curtain or the air knife according to the diameter size of the roll 50. [

As described above, since the printing roll manufacturing apparatus 300 according to the first and second embodiments of the present invention is used after the thin film coating 54 is formed on the surface 52 of the roll 50, The applied coating liquid is prevented from flowing on the roll surface before the roll 50 is moved to the hardening device. The thickness uniformity of the applied coating film 54 on the surface 52 of the roll 50 is thereby significantly improved.

In addition, in the printing roll manufacturing apparatus 300 according to the first and second embodiments of the present invention, since the coating thin film 54 is toughened, it is prevented that foreign matter is adhered or introduced into the coating thin film 54 , The possibility of scratching of the coating film 54 is reduced. As a result, the quality of the final product is greatly improved.
