Abstract

The present invention relates to a method of manufacturing a gravure printing roll, the method which enables the gravure printing roll to manufacture a multilayer ceramic capacitor (MLCC) by using a conductive paste that is an electronic ink. More specifically, a conventional method of manufacturing the gravure printing roll comprises the steps of: electrodepositing nickel on the outer surface of an iron roll (24) to form a nickel plating layer having a thickness of 5 μm; covering the nickel plating layer with copper to form a copper plating layer (22) having a thickness of 120 to 130 μm; and electrodepositing chromium on the copper plating layer to form a chromium plating layer having a thickness of 6 μm, thereby manufacturing an ordinary roll for a gravure printer. However, a method of manufacturing a high hardness gravure printing roll of the present invention comprises the steps of: changing an electrodeposition process into a shrinkage fitting process by shrinkage fitting brass or bronze that is a copper alloy metal (32, 43) having very high hardness and strength onto the outer surface of a gravure iron roll to a thickness of 7 μm without electrodepositing the nickel plating layer (23) and the copper plating layer (22); performing processing and polishing processes on a metal surface to obtain a copper alloy metal; plating copper (42) on the outer surface of the copper alloy metal (43) to a thickness of 20 to 30 μm; designing a pattern of the MLCC on a surface of a copper alloy metal (32); and performing an etching process on the MLCC pattern-designed surface of the copper alloy metal. Therefore, the method according to the present invention enables the gravure printing roll to stably produce high quality MLCCs, all IT electronic components and the like printed by using high quality electronic inks by manufacturing a gravure printing roll of which surface is manufactured from a chromium plating layer (31, 41) having a thickness of 5 to 6 μm and has a 50 to 60% higher hardness than that of the gravure printing roll manufactured by the conventional method, and which has very good wear resistance compared to the gravure printing roll manufactured by the conventional method.

Description

고경도 그라비아 인쇄롤 제조방법{High hardness gravure printing roller manufacturing method}Technical Field The present invention relates to a high hardness gravure printing roller manufacturing method,

본 발명은 전자잉크 등의 금속성 잉크를 사용하는 그라비아 인쇄롤 표면에 적층 세라믹 콘덴서(MLCC), LCD 모니터, 전자테크(RFID TAG), 플렉시블 인쇄 회로기판(FPCB)등 적합하게 미세패턴을 디자인하여 다양한 IT 전자부품들을 생산하기 위한 초정밀 그라비아 인쇄롤로 인쇄품질을 향상시킬 수 있는 고경도 그라비아 인쇄롤의 제조방법에 관한 것이다.The present invention designs fine patterns appropriately such as a laminated ceramic capacitor (MLCC), an LCD monitor, an electronic tag (RFID TAG), and a flexible printed circuit board (FPCB) on the surface of a gravure printing roll using a metallic ink such as electronic ink, The present invention relates to a method of manufacturing a high-hardness gravure printing roll capable of improving printing quality with an ultra-precise gravure printing roll for producing IT electronic parts.

근래에는 대전류 및 고온에서 행하는 경질 크롬도금을 한 그라비아 인쇄(Gravure Printing)롤을 이용하여 각종 필름표면에 인쇄하여 포장용으로 널리이용되고 있다. 일반적으로 적층 세라믹 콘덴서(MLCC)와 같은 전자부품을 제조하기 위해 내부전극이 되는 전도성 페이스트가 패턴에 담긴 상태로 회전하면서 세라믹 그린시트 상에 인쇄되는 공정이 실시되는데, 이와 같은 전도성 페이스트에 의해 제공되는 내부전극은 높은 패턴의 정밀도를 가져야만 한다. 그러므로 패턴의 높은 정밀도를 같기 위해서는 표면경도가 높은 그라비아 인쇄롤를 적용할 필요가 있다.       BACKGROUND ART [0002] In recent years, gravure printing rolls having hard chrome plating at high current and high temperature have been widely used for packaging by printing on various film surfaces. Generally, in order to produce an electronic component such as a multilayer ceramic capacitor (MLCC), a process is performed in which a conductive paste serving as an internal electrode is printed on a ceramic green sheet while rotating in a state containing a pattern. The internal electrodes must have high pattern accuracy. Therefore, it is necessary to apply a gravure printing roll having a high surface hardness in order to achieve high pattern accuracy.

이와 같은 그라비아(Gravure) 인쇄방법은 적층 세라믹 콘덴서 전자부품 이외에도 다양한 전자부품을 생산하는데 이용되고 있으며, 그라비아 인쇄롤의 표면경도에 따라서 마모상태가 좌우된다. 전극 페이스트를 사용하는 그라비아 인쇄는 도 1에 도시된 바와 같이 그라비아 인쇄기를 이용한다. 이는 그라비아 인쇄롤(14)과 시트(13)를 가압하는 가압롤(12)로 구성되어 있다.       Such a gravure printing method is used for producing various electronic parts in addition to multilayer ceramic capacitor electronic parts, and the abrasion state depends on the surface hardness of the gravure printing roll. The gravure printing using the electrode paste uses a gravure printing machine as shown in Fig. It consists of a gravure printing roll 14 and a pressing roll 12 which presses the sheet 13.

이에 따라서 그라비아 인쇄롤(14)과 가압롤(12)이 회전하면서 시트가 이송되는데, 이때 그라비아 인쇄롤 하부에 설치된 잉크사라(16) 내부에 수용되어 있는 전극 페이스트(15)가 그라비아 인쇄롤의 원주면에 형성되어 있는 패턴에 담긴 상태로 회전하면서 시트(13) 상에 전극 페이스트가 인쇄된다. 특히 그라비아 인쇄롤의 원주면상의 여분의 전극 페이스트(전자잉크)는 강한 압력을 받고 있는 닥터 블레이드(Doctor blade)(11)에 의해 밑으로 긁어 내려진다.       In this case, the electrode paste 15 accommodated in the ink sara 16 provided under the gravure printing roll is fed to the circulation path of the gravure printing roll 14 and the pressing roll 12, The electrode paste is printed on the sheet 13 while being rotated in the state of being contained in the pattern formed on the main surface. Particularly, the extra electrode paste (electronic ink) on the circumferential surface of the gravure printing roll is scraped down by the Doctor blade 11 under strong pressure.

그러므로 그라비아 인쇄롤 표면은 닥터 블레이드와 전도성 페이스트의 무기안료에 의한 마찰로 마모된다. 이로 인해 그라비아 인쇄롤(14) 패턴의 정밀도가 떨어져 인쇄품질이 저하되고 생산량이 감소되는 문제점을 야기 시키게 된다.        Therefore, the gravure printing roll surface is worn by the friction caused by the inorganic pigment of the doctor blade and the conductive paste. This results in a problem that the accuracy of the gravure printing roll 14 pattern is reduced, the printing quality is lowered, and the production amount is decreased.

본 발명은 상술한 바와 같이 종래 기술의 문제점을 해결하고자 하는 것으로 그라비아 인쇄롤은 다양한 IT 전자부품 등을 생산하는데 사용되고 있으며, 특히, 전자잉크로 MLCC를 인쇄하는 것은 매우 작은 오차도 허용되지 않기 때문에 정확한 셀들의 간격과 셀들을 에칭한 단면적이 완벽하여야 하기 때문에 롤 표면이 마모되어서는 안되다.As described above, the present invention is intended to solve the problems of the prior art. Gravure printing rolls are used to produce various IT electronic parts and the like. In particular, since printing of MLCC with electronic ink is not allowed, The roll surface should not be worn because the cell spacing and cross-sectional area of the cells must be perfect.

이와 같이 포장용 그라비아 인쇄롤을 제작 사용했던 종전의 방식으로 그라비아 인쇄롤을 동일하게 제작하여 IT 전자부품 및 MLCC을 만든는 그라비아 인쇄롤로 사용시, 인쇄기의 가압롤과 닥터 블레이드에 사용하는 압력이 포장용보다 매우 높기 때문에 그라비아 인쇄롤의 표면경도가 낮아 닥터 블레이드에 의해 그라비아 인쇄롤의 표면이 마모되는 경향이 빠르고, 또 크롬도금층이 뜯어지는 현상과 마모에 의해 생긴 미세한 이물질들이 전자잉크인 페이스트에 혼입되어 인쇄된 제품들이 불량으로 이어지는 것을 기술적 과제로 한다.When the gravure printing rolls are manufactured in the same manner as the conventional method of manufacturing the gravure printing rolls for packaging and the IT electronic parts and the MLCCs are used as the gravure printing rolls, the pressure applied to the press rolls and the doctor blade of the printing presses is much higher The surface hardness of the gravure printing roll is low and the surface of the gravure printing roll tends to be worn away by the doctor blade. Also, the phenomenon that the chromium plating layer is torn and the minute foreign matter generated by the abrasion are mixed in the electronic ink paste, The problem is to lead to defects.

상기 목적을 달성하기 위하여 본 발명은 그라비아 인쇄롤의 제작에 있어 발명전에는 철롤(24) 외피에 니켈 스트라이크도금(23)과 구리도금(22)을 120~130㎛ 두께로 하던 것을 배제하고, 구리보다 경도와 강도가 매우 높은 구리합금금속 (32,43)을 두께 7㎜의 황동 또는 청동 파이프를 150~200도로 30분간 가열로에서 가열하여 그라비아 철롤(33,44)의 외피에 열박음하여 자연냉각시키고, 금속표면을 가공과 연마를 한 구리합금금속(43) 외피에 20~30㎛ 두께로 구리도금(42)을 하고 패턴을 에칭하고 크롬도금을 하여 상기한 문제점을 해결하고자 한다.       In order to accomplish the above object, the present invention provides a method of manufacturing a gravure printing roll, which comprises the steps of removing nickel strike plating (23) and copper plating (22) on the outer surface of iron roll (24) A brass or bronze pipe having a thickness of 7 mm is heated in a heating furnace at 150 to 200 degrees for 30 minutes to shrink the copper alloy metal (32, 43) having very high hardness and strength to the outer surface of gravure iron rolls (33, 44) And copper plating 42 is applied to the outer surface of a copper alloy metal 43 having a metal surface processed and polished to a thickness of 20 to 30 μm, and the pattern is etched and chromium plating is performed.

발명한 그라비아 인쇄롤의 표면경도가 종래의 그라비아 인쇄롤 보다 50~60%(도 7 사진참조) 향상되어 인쇄롤의 문제점인 표면마모가 없어져 그라비아 인쇄롤의 원주면 상에 형성된 패턴의 정밀도가 유지되고, 크롬도금층이 뜯어지고, 크롬층이 마모에 의해 구리도금층이 노출되는 현상이 없어져 인쇄품질을 올릴 수 있어 안정적인 MLCC의 전자부품을 생산할 수 있었다. 그리고 전자산업 등의 정밀산업분야에 적용시 안정적인 전자부품의 생산이 가능해지는 장점도 있다.The surface hardness of the inventive gravure printing roll is improved by 50 to 60% (see FIG. 7) than that of the conventional gravure printing roll, so that the surface wear which is a problem of the printing roll is eliminated and the precision of the pattern formed on the circumferential surface of the gravure printing roll is maintained The chromium plated layer was torn and the chromium layer was not exposed to the copper plating layer by the abrasion, so that the print quality could be improved and the stable electronic component of the MLCC could be produced. In addition, when applied to precision industries such as the electronics industry, it is possible to produce stable electronic components.

Rolls are made, annealed for annealing, and then slowly cooled in a furnace.

이어서 풀림 열처리한 반가공 그라비아 롤을 정삭 가공한 다음, 철롤 외피의 구리도금층(22)보다 경도와 강도가 매우 높은 구리합금금속(32,43)인 황동 혹은 청동금속으로 두께 7㎜, 내경 둘레 430㎜, 길이 550㎜를 가공한 파이프를 150~200도에서 30분간 가열로에서 가열한 다음, 즉시 반가공한 그라비아 롤을 위에서 아래로 열박음하여 자연냉각시키고, 이어서 그라비아 롤의 구리합금금속 표면을 정밀가공과 연마를 한 구리합금금속(43) 외피에 두께 20~30㎛ 구리도금(42)을 전착시키다.Next, after finishing the semi-finished gravure roll subjected to the annealing heat treatment, a brass or bronze metal of copper alloy metal (32, 43) having a hardness and an extremely higher hardness than the copper plating layer 22 of the iron steel shell is 7 mm thick, Mm and a length of 550 mm was heated in a heating furnace at 150 to 200 degrees for 30 minutes, and immediately after the gravure roll which had been semi-finished, was heat-shrunk from top to bottom to cool the copper alloy metal surface of the gravure roll A copper plating 42 having a thickness of 20 to 30 mu m is electrodeposited on the outer surface of the copper alloy metal 43 subjected to precision machining and polishing.

그리고 그라비아 롤을 정밀연마기로 직경 149㎜로 가공 후, 표면을 빠우기로 광택 연마한 다음, 37도 건조로 내부에서 3분간 열풍기로 건조 시킨 후, 롤을 양끝단 척에 고정하여 회전시키면서 표면에 감광막을 균일하게 도포하고 10시간 정도 자연건조 시킨다. 이어 그라비아 롤의 구리합금금속(32)과 구리도금층(42) 표면에 레이저 노광기를 이용해 각각 노광 작업을 마친 후, 알칼리 현상액에 롤의 하반부를 침지 회전하여 약 1분 정도 현상처리 후, 식각에 의한 셀의 형성을 위해 에칭(부식) 공정을 거쳐 부식방지와 내마모성을 위해 두께 5~6㎛의 크롬도금층(31,41)을 전착시키고, 3㎛ 롤 페이퍼로 표면을 습식연마 한다.The surface of the gravure roll was processed with a precision grinder to a diameter of 149 mm. The surface was polished with a spatula, followed by drying at 37 ° C. for 3 minutes with hot air. The roll was fixed to both ends of the chuck, The photosensitive film is uniformly applied and air-dried for about 10 hours. Subsequently, each of the copper alloy metal 32 and the copper plating layer 42 of the gravure roll was exposed to light using a laser exposure machine. Subsequently, the lower half of the roll was immersed and rotated in an alkali developing solution for about one minute, A chromium plating layer 31 or 41 having a thickness of 5 to 6 μm is electrodeposited for corrosion prevention and abrasion resistance through an etching process to form a cell and the surface is wet polished with a 3 μm roll paper.
