The construction and operation of the roll-to-roll substrate transfer device of the U.S. Publication No. 2009-0159210 for the roll-to-roll apparatuses can be seen in that the roll-to-roll apparatus is moving various processing operations on the substrate while moving the substrate in the horizontal direction . When the development or etching process is performed while the substrate is transferred in the horizontal direction, there is a problem that the processing member such as the substrate or the processing film strikes in the gravitational direction due to the phenomenon that the liquid sprayed through the injection nozzle is accumulated in each process. Such stubbing phenomenon not only deteriorates the reliability of the roll-to-roll processing, but also has a problem of adversely affecting productivity of the product, such as occurrence of defective products. Particularly, in the case where various complicated processing steps are performed, there is a problem that such a processing phenomenon is more pronounced.

FIG. 1 is a perspective view of a roll of a roll-to-roll apparatus according to an embodiment of the present invention, and FIG. 2 is a perspective view of a roll of a roll-to-roll apparatus according to another embodiment of the present invention.

The roller 10 according to an embodiment of the present invention includes a processing roll 11 formed to extend in the longitudinal direction; And a pair of stepped portions 12b (12b) extending from both side ends of the processing roll 11 and being in contact with both side ends of the processing member 30 so that the processing member 30 does not contact the processing roll 11 (Not shown).

1, the roller 10 includes a part of the processing roll 11 formed to correspond to the processing member 30 at the center and a part of the step roll 11 formed at both sides of the processing roll 11 in the longitudinal direction, (12) may be combined with each other. Particularly, the roller 10 according to the embodiment of the present invention is configured such that the stepped portion 12b is formed at the joining portion of the processing roll 11 and the step roll 12, So as to move the machining member 30 and make it possible to contact the machining roll 11 in a substantially processed and moving portion. The rollers 10 can be configured such that the diameter of the step rolls 12 is larger than the diameter of the processing rolls 11 to form the stepped portions 12b if a general cylindrical roller 10 is used.

The processing roll 11 of the roller 10 maintains the noncontact state with the processing member 30 so that the processing member 30 can be printed in a series of processes such as forming a circuit layer such as a printed circuit board It is possible to prevent the contamination and damage of the processed surface of the circuit board and the reliability of the processing from being deteriorated.

The roller 10 according to another embodiment of the present invention constitutes a protruding portion 12a at a portion where the step roll 12 of the roller 10 contacts the processing member 30 and the protruding portion 12a corresponding to the protruding portion 12a By forming the grooves 31 in the machining member 30, the machining member 30 can be moved more effectively through the roller 10. [ As will be described later, when the processing member 30 in the roll-to-roll apparatus moves in a roll-to-roll manner in order to pass through various processing steps, the processing member 30 is moved in contact with both side ends of the processing member 30 There is an advantage that more precise movement control can be realized through such a physical structure than by simply using the frictional force between the processing member 30 and the step roll 12. 2, even if only one roller 10 is engaged with the processing member 30 at the time of the movement of the processing member 30, the movement control of the processing member 30 can be smoothly performed It can be done.

FIG. 3 and FIG. 4 are schematic processing diagrams of a roll-to-roll apparatus according to an embodiment of the present invention.

The roll-to-roll apparatus according to an embodiment of the present invention includes a first roller 10a formed to move the processing member 30 in the horizontal direction, a first roller 10a vertically downward from the first roller 10a, A third roller 10c formed so that the processing member 30 moves in the horizontal direction from the second roller 10b and a third roller 10b formed so as to move from the third roller 10c And a fourth roller 10d formed so that the processing member 30 moves in a vertical upward direction.

Herein, the vertical upward or downward direction does not specify any particular direction, but refers to the upper and lower portions of one direction in the direction of gravity, It is not.

As shown in FIG. 3, in the description of the roll-to-roll apparatus according to an embodiment of the present invention, the processing member 30 is formed to pass through the dipping chamber 40 serving also as a dipping system, , The roll-to-roll apparatus according to the present invention is configured such that the machining direction of the machining member 30 is perpendicular to the machining surface of the machining member 30, which is partially caused by the extra force applied in the gravity direction, 30, the kind of the processing and the processing method thereof can be all included in the design change according to the technical idea of the roll-to-roll apparatus of the present invention.

Hereinafter, a roll-to-roll apparatus according to an embodiment of the present invention will be described with reference to FIG.

The first roller 10a is disposed before the first machining member 30 is subjected to the machining step so as to move the machining member 30 entering in the horizontal direction. Although the first roller 10a shown in Fig. 3 shows that the pair of first rollers 10a are moving through the processing member 30, in another embodiment of the roller 10, It is obvious that the movement of the processing member 30 in the horizontal direction and the vertical direction can be controlled even if one roller 10 is used through the projecting portion 12a of the roll 12. [ The first roller 10a moves the processing member 30 to the second roller 10b that extends in the vertical direction for the machining step, in which the machining member 30 enters in the horizontal direction. The feature according to the embodiment of the present invention is that the processing step of the processing member 30 is not performed in the horizontal direction rolling apparatus but is processed while moving in the vertical direction so that the first roller 10a and the second It is appropriate that the arrangement of the rollers 10b is arranged so as to have a predetermined inclination in the vertical direction, at least according to the technical idea of the present invention. For example, in the case where a liquid processing liquid is applied to the processing member 30 in the processing step, if the processing liquid has an inclination angle enough to naturally flow from the upper portion to the lower portion without being fixed to the processing member 30 And can be included in the technical idea of the present invention.

The second roll moves the processing member 30 from the first roller 10a in the vertical downward direction. At this time, since the vertical liquid ejection apparatus 20 is provided between the first roller 10a and the second roller 10b, the specific processing surface can be processed while moving the processing member 30 in the vertical direction . The vertical liquid ejection apparatus 20 can be disposed at a position corresponding to the processing surface of the processing member 30 so that the processing liquid is ejected from the injection nozzle 21 of the vertical liquid ejecting apparatus 20. [

Next, the next machining of the primary processed workpiece 30 may be made to pass through the dipping chamber 40. Since the dipping liquid 41 is impregnated in the dipping liquid 41 of the dipping zone 40, it is possible to move the processing member 30 in the horizontal direction have.

The fourth roller 10d can move the processing member 30 in the vertical upward direction from the third roller 10c. In this case, the fourth roller 10d has a function and a configuration similar to that of the first roller 10a, and can move the processing member 30 in the vertical upward direction. The next step processing of the processing member 30 can be performed by the vertical liquid ejecting apparatus 20 also here. By moving the processing member 30 in the vertical upward direction, the impregnated dipping liquid 41 in the dipping chamber 40 can be partially prevented from remaining high or remaining, thereby preventing the reliability of the machining from being deteriorated.

Through the first roller 10a to the fourth roller 10d, the processing member 30 can be subjected to machining processes of up to three stages, and the machining process steps can be adjusted through appropriate control in each section. By combining at least one of these modules, it is possible to more reliably implement a large number of complicated processing processes through the roll-to-roll apparatus.

For example, as shown in Fig. 4, a series of processing steps can be performed with the processing steps of the processing member 30 interlocked in the roll-to-roll method in each of the steps A to G. [ That is, step A is a developing step, step B is a washing step, step C is an etching step, step D is a washing step, step E is a peeling step, step F is a washing step, step G is a rust- It can be rough. Particularly, when the roll-to-roll apparatus according to the present invention is used, it is possible to easily adjust the process processor even when the machining process of a specific section is omitted, without the need of exchanging or adding special equipment. 5, for example, in the case where steps C to E are to be omitted, the processing member 30 is moved in the horizontal direction immediately without being inserted in the vertical direction of the processing step, There is an advantage that the processing step of the processing member 30 can be controlled.

4 and 5 are well-known terms and methods generally used in a method of manufacturing a printed circuit board and the like, and a detailed description thereof will be omitted.

Although the present invention has been described in detail with reference to the specific embodiments thereof, it is to be understood that the present invention is not limited to the roller and the roll-to-roll apparatus including the roller according to the present invention, It will be apparent that modifications and improvements can be made by those skilled in the art.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
