<Notice 70 is a cutting unit for cutting the printing paper to the appropriate size>

Such a roll-to-roll rotation printing press uses a plurality of gravure offset printing units 20 which are not adopted in the conventional in-line multicolor image printing. This type of printing unit utilizes the high resolution and the wide range of ink volume forming ability, which are advantages of gravure printing, and the flexibility of the rubber itself and the unique ink transition characteristics of the silicone rubber surface from the pad printing method. As a result, each component circuit pattern of an electronic circuit element having a three-dimensional structure was superimposed and printed one by one in a printing unit. As a result, all the electronic elements were consistently completed in one printing machine.

In the printing unit 20, the pressure control between the forming roll 23 and the printing roll 26 and between the printing roll 26 and the pressure roll 28 is very important.

That is, when the ink of the forming groove 23a on the forming roll 23 is rotated in one direction with the printing roll 26 to make a contact transition, when the pressure is too low, the printing roll 26 is formed on the upper portion of the forming groove 23a. ) If the surface is not sufficiently adhered and the circuit pattern is not faithfully transferred to the surface of the printing roll, on the contrary, if the pressure is too high, the ink of the main portion of the forming groove 23a escapes the pattern boundary and the line gain becomes large, resulting in poor resolution. .

Therefore, the pressure between the forming roll 23 and the printing roll 26 is not only constant, but also needs to be appropriately adjusted according to the viscoelasticity of the ink, the size of the forming groove for the circuit pattern, and the silicone rubber hardness that is the coating of the printing roll 26. There is.

Further, the printing pressure when the ink on the printing roll 26 has the second transition process again to the printing paper (substrate) 1 engaged with the pressure roll 28 is the printing roll 23 in the forming roll 23. The desired resolution and ink thickness can be secured only by adjusting the pressure slightly higher or incorrectly than the transfer pressure to (26) so that it remains constant.

As such, the printing pressure in the printing unit 20 must be operated with a precisely controlled pressure control system so that the required ink shape can be transferred as accurately as possible, so that the micro-pattern of the IC chip by the roll-to-roll can be printed out. It can be prepared in the above.

However, in the above-mentioned basic patent, although the first pressure regulating device (not shown) and the second pressure regulating device (not shown) of the printing unit 20 are installed, specifically, the pneumatic cylinder can be operated, and this pneumatic The cylinder is only outlined that the pressure is constantly maintained at a constant pressure by the pressure regulating means at all times, and thus a specific complementary technology is required.

Accordingly, the present invention develops a specific device that can maintain a constant printing pressure at all times as the appropriate contact pressure between the rolls are automatically adjusted, the pressure of the roll-to-roll rotation printing system that can produce and supply high-quality products In providing a control device.

Specifically, in the step of transferring the functional ink of the forming roll to the printing roll and the transferring of the functional ink of the printing roll onto the printing paper, a constant pressure is applied to the forming roll when the forming roll and the printing roll are rotated in one direction in contact with each other. This pressure is applied to the first phosphorous pressure control device so that the functional ink can be transferred to the printing roll well, and a constant pressure is applied to the pressing roll when the printing roll rotates in one direction when the pressing roll is in contact with the printing paper. The present invention provides a pressure-to-roll control system of a roll-to-roll rotoprinting system having a second pressure-controlling device that allows the functional ink to be transferred to printing paper well.

Various ink thicknesses enable more precise printing and solidify the foundation for producing various electronic products on the press.

Particularly, in the roll-to-roll rotation printing method, which enables good printing even at a very low printing pressure (1/10 to 1/30) unlike general offset printing and gravure printing, the difference in ink layer thickness varies greatly depending on the minute pressure difference. Therefore, it is necessary to have a pressure system that automatically feeds back and precisely adjusts the pressure to print the correct ink layer thickness.

Once the functional ink 2 is supplied to the ink container 21, the forming roll 23 having the uniform dispersion of ink is continuously formed by the rotation of the ink injection roll 22 and the empty forming groove 23a is formed. The ink is filled in the forming groove in close contact with the ink injection roll 22 when the ink container is locked by rotation. Ink buried together on the surface of the forming groove and the forming roll, the ink remaining on the surface of the forming roll is wiped by the doctor blade 24 as the forming roll is raised, so that only the ink remains in the forming groove 23a.

Next, the forming roll 23 is in contact with the printing roll 26 by a constant pressure by the first pressure control device 110 for adjusting the contact pressure between the forming roll 23 and the printing roll 26. At this time, the ink remaining in the forming groove is hardened to some extent by the first drying unit 25 that blows warm air, thereby increasing the cohesive adhesion and transferring to the silicon rubber surface of the printing roll. The ink transferred to the printing roll 26 is reversed from that of the forming groove 23a so that the ink surface on the forming groove is attached to the silicon rubber surface of the printing roll, and the ink surface inside the forming groove is exposed to the air. It is again surface-dried by the second drying unit 27 and has a considerably higher viscoelasticity than when it is in the ink container in a solidified state to some extent. At this time, the pressure roll 28 is contacted with the printing roll 26 at a constant pressure by the second pressure control device 120 for adjusting the contact pressure between the printing roll 26 and the pressure roll 28. The ink of the printing roll is transferred to the printing paper 1 passing through. Thus, the ink is transferred to the printing paper satisfactorily without collapse of the printing pattern shape even by the high gap pressure between the press roll 28 and the printing roll 26.

As described above, the ink transition from the ink container 21 to the printing paper 1 is performed through two in-pressure transfer processes and two instant drying processes, and the quality is excellent, that is, the acquisition of fine print patterns of precise electronic devices requires two pressures. It depends on the pressure by the regulator and hot air drying in the instant drying process.

The conditions under which the ink is transferred by pressure include the surface energy correlation of the surface of the silicon rubber of the printing roll 26, the hardness of the printing roll silicone rubber, and the forming roll 23 and the pressure roll that pressurize the printing roll. 28) depends on the degree of close contact. In particular, the adhesion pressure plays an important role in forming the resolution accuracy and thickness of the printing ink pattern.

Accordingly, the present invention provides a pressure control device capable of applying a more precise printing pressure and maintaining it in a constant control manner in order to obtain an appropriate thickness of a functional ink layer as an electronic device, unlike general image printing.

The pressure control device includes a forming roll 23 and a printing roll 26 in a printing unit; The surfaces of the printing roll 26 and the pressing roll 28 are in parallel contact with each other in parallel and rotated in one direction so that ink passes through the printing roll 26 and the printing roll 26 and the pressing roll 28 from the forming roll 23. ) Is transferred to the printing paper (substrate) sandwiched between, wherein the pressure between the forming roll 23 and the printing roll 26 and the printing roll 26 and the pressure roll 28 facing each other The first and second pressure regulating motors 115 and 125 fixed to the frame 101 while the first and second bearing blocks 112 and 122 are supported on the first and second guiders 113 and 123 on both sides of the respective axes of the roll 28. It is to be applied to the surface of the printing roll 26 in connection with the screw shaft (115d, 125d) that is precisely pushed by the rotation. One side of all the screw shafts 115d and 125d is driven forward and backward by rotating nuts 115c and 125c which rotate together with the rotors of the first or the second induction motors 115 and 125 and the other ends of the first and second ends of the screw shafts 115d and 125d. Connected to the first and second load cells 114 and 124 fixed to the bearing blocks 112 and 122, the strength of the pressure applied by the driving of the pressure regulating motor is sensed and fed back to the pressure regulating motor to be adjusted.
