Definitions

  • the present invention relates to a thin-film forming apparatus, which includes, as an apparatus for forming a macromolecular thin-film pattern used for the electronic parts such as a liquid crystal orientation film, for example, an intaglio roll having a plurality of ink cells; an ink supply means which fills ink into the ink cells; a printing roll having an elastic plate, to which the ink of the intaglio roll is transferred, on the barrel; a printing table which fixes the to-be-printed material, to which the ink of the printing roll is transferred; a doctor blade to ensure to fill the ink into the ink cells of the intaglio roll; and a robot which operates for the printing roll and the intaglio roll, and a thin-film forming method which uses the thin-film forming apparatus to form a thin-film. More particularly, the present invention relates to a thin-film forming apparatus and a thin-film forming method which can carry out at least one of the followings:
  • the printing preparatory works such as mounting/dismounting of the elastic plate, and wiping out of the intaglio roll and the doctor blade, are carried out by the operator by hand, before the printing operation.
  • marks for positioning provided in plural places of the elastic plate and reference marks provided in plural places of the barrel of the printing roll are first positioned by the operator's hand(s) and the eyes of the operator, and the elastic plate is stretched by the operator's hand(s) to be wound to the barrel of the printing roll. Afterwards, elastic plate holders which are mounted on both ends of the elastic plate are fixed by the operator's hand(s), by hooking them to chuck means mounted on the barrel of the printing roll.
  • the ink is filled into the plurality of ink cells of the intaglio roll by an ink supply means, transferred from the intaglio roll to the elastic plate of the printing roll, and transferred from the printing roll to the to-be-printed material which is fixed on the printing table to carry out the printing.
  • the elastic plate holders mounted on both ends of the elastic plate are dismounted by the operator's hand(s) from the chuck means on the barrel of the printing roll.
  • the whole ink filled into the ink cells of the intaglio roll is not always transferred to the printing roll, and a part of the ink remains in the ink cells of the intaglio roll. If the residual ink is left as it is, the residual ink will be dried or stiffened to be ink solid, and the ink solid adheres to the inner part of the ink cells. If the intaglio roll is used as it is, the adhered ink is redissolved in new ink, or the ink solid drops out to be mixed in the new ink supplied to the intaglio roll, thereby the deteriorated ink is used for the printing. Furthermore, since the ink adhered to the ink cells decreases the volume of the ink cells, the transferred amount of the ink to the printing roll is decreased by that amount.
  • the residual ink in the ink cells of the intaglio roll is wiped out, which is done all by the operator's hand(s). Namely, a wiper is first penetrated with solvent which dissolves the ink, and pressed by the operator's hand against the barrel surface of the intaglio roll so that it becomes a predetermined contact pressure, and is moved along the axial direction of the intaglio roll, while rotating the intaglio roll in the state that the wiper is pressed against it.
  • the intaglio roll is dried.
  • a gas ejecting means which ejects gas for drying the intaglio roll is first placed by the operator's hand(s) so that there is a predetermined distance between the gas ejecting means and the barrel surface of the intaglio roll, and while ejecting the gas to the barrel surface of the rotating intaglio roll, the gas ejecting means is moved by the operator's hand(s) along the axial direction of the intaglio roll while rotating the intaglio roll.
  • the ink is filled into the plurality of ink cells of the intaglio roll by the ink supply means, transferred from the intaglio roll to the elastic plate of the printing roll, and transferred from the printing roll to the to-be-printed material which is fixed on the printing table to carry out the printing.
  • the doctor blade is a plate-shaped body, and mounted to the doctor blade-supporting rod (see Fig. 27). Since the doctor blade has a function to scrape off ink on the barrel surface of the rotating intaglio roll, and to ensure and measure the filling of the ink into the ink cells of the intaglio roll, if the doctor blade to which the ink is adhered is left as it is, the adhered ink is dried or stiffened to become ink solid, and the ink solid is adhered to the doctor blade.
  • the adhered ink is redissolved in new ink, or the ink solid drops out to be mixed in the new ink supplied to the intaglio roll, thereby the deteriorated ink is used for the printing. Furthermore, since the tip of the doctor blade becomes uneven due to the adhered ink, the removing unnecessary ink cannot be done evenly, and it becomes difficult to secure the filling into the all ink cells of the intaglio roll and measuring the ink amount.
  • the ink adhered to the doctor blade is wiped out, which is done all by the operator's hand(s).
  • the wiper first penetrated with solvent, is held in the operator's hand(s) to hold the doctor blade between them with a predetermined contact pressure, and are moved along the longitudinal direction of the doctor blade in the state that the doctor blade is put therebetween. Then, in order to remove the solvent which stays behind on the doctor blade, the doctor blade is dried by the operator's hand(s).
  • a gas ejecting means which ejects gas for drying the doctor blade is placed by the operator's hand(s) so that there is a predetermined distance between the gas ejecting means and the doctor blade, and while ejecting the gas to the doctor blade, the gas ejecting means is moved by the operator's hand(s) along the longitudinal direction of the doctor blade.
  • the ink is filled into the plurality of ink cells of the intaglio roll by the ink supply means, transferred from the intaglio roll to the elastic plate of the printing roll, and transferred from the printing roll to the to-be-printed material which is fixed on the printing table to carry out the printing.
  • the object of the present invention is to overcome the above-mentioned problems, and to provide a thin-film forming apparatus and a thin-film forming method which can improve the functions of the thin-film and the working efficiency, by automating the printing preparatory works without using operator's hands.
  • a thin-film forming apparatus which includes a printing device having an intaglio roll having a plurality of ink cells, an ink supply means which fills ink into the ink cells, a doctor blade for wiping the barrel surface of the intaglio roll, a printing roll having an elastic plate, to which the ink of the intaglio roll is transferred, wound on the barrel thereof, and a printing table which fixes the to-be-printed material, to which the ink of the printing roll is transferred, wherein it is constituted so that it includes a articulated robot provided adjacent to the printing device, and an implementation means for the printing preparatory works which performs at least one operation among mounting/dismounting operation of the elastic plate, which is mounted to the arm of the articulated robot, to/from the printing roll, the operation to wipe the ink in the periphery of the intaglio roll, and

  • the distance between the hand body of the elastic plate automatic mounting/dismounting device of the present invention and the stretching chuck means varies automatically according to the magnitude of the tension applied to this elastic plate.
