Definitions

  • the invention relates to a method for producing means and an arrangement of the means for generating a sequence of charged, detected and deflected ink drops for an inkjet printer.
  • an electromagnetic device provided with appropriate means is required. With the device assigned to a spray body, individual drops are charged, detected and deflected in correspondingly generated electrical fields, as a result of which a text field is created on a correspondingly assigned writing point.
  • the relatively closely arranged electronic means due to the relatively aggressive and chemical reactions leading to ink reactions, can smear and clog and thereby cause an electrical short circuit. Such defects often make the inkjet printer inoperable or completely unusable.
  • the known devices have a relatively complex, constructive structure and are not suitable, or only with great technical outlay, for the arrangement of a plurality of closely adjacent spray bodies, as are required, for example, for inkjet printers in order to achieve seamless graphic representations.
  • Object of the present invention is on the one hand the production of improved means for functionally reliable He witness charged, detected and deflected ink drops and on the other hand the arrangement of the means for achieving seamless graphics in an inkjet printer.
  • the particular advantage of the present invention with regard to the method is that, using the circuit board manufacturing technology known per se, the means for producing the charged, detected and deflected ink drops can be produced economically and with optimum electrical properties.
  • Another advantage is that due to the plate-like means - compared to the previously known and block-like means - a much narrower and smaller design is achieved.
  • a major advantage is also seen in the fact that, in a sandwich construction of the two carrier elements comprising the ink drop deflecting means, several spray bodies can be arranged at a short distance from one another, and thus seamless, graphic representations can be achieved without further technical outlay.
  • FIG. 1 shows a perspective view of an arrangement, designated as a whole by 50, with means for charging, detecting and deflecting ink drops in an inkjet printer.
  • the arrangement 50 comprises a first structural unit 25 with the means for charging and detection and a second structural unit 45 with the means for deflecting the ink drops.
  • a schematically represented spray body 60 can be seen in FIG. 1, from which a number of ink drops, shown in simplified form by a line 65, is fed to the arrangement 50.
  • the ink drops fly through the first structural unit 25, which is essentially composed of two carrier elements 5 and 10, which are spaced apart by a spacer 15, and the second assembly 25, which is essentially composed of two carrier elements 30 and 40, which are spaced apart by a spacer 35 Unit 45.
  • FIG. 2 shows in a sectional view, without the two spacer parts 15 and 35, a part of the arrangement 50 and one can see the carrier element 5 of the first structural unit 25 and the carrier element 40 of the second structural unit 45, which in FIG -IV in Fig. 2 is posed.
  • the second structural unit 45 is shown in a front view according to arrow direction A in FIG.
  • first structural unit 25 The details of the first structural unit 25 and the details of the second structural unit 45 are described in more detail below with reference to FIGS. 5 to 8.
  • the first carrier element 5 shown in view, which is formed from a polyimide substrate provided with a metal lamination.
  • the means for charging and detecting the ink drops are formed on one surface side 5 'in the desired shape, 8 being a charging electrode and 7 being a detection electrode.
  • the detection electrode 7 is preferably surrounded by a shield 6 formed from the lamination and is thereby insulated on one side from the charging electrode 8 and on the other side from a deflection electrode 41 (FIG. 2) of the second structural unit 45.
  • the elements 6, 7 and 8 are connected to correspondingly designed and mutually arranged conductor tracks 6 ', 7' and 8 'with an electrical connection point 1, 2, 3 and 4.
  • FIG. 7 shows the other surface side of the first carrier element 5, which is also provided with a metal lamination and is not designated in more detail, in which an ab is removed by removing lamination that is not required distortion 9 is provided.
  • the outer shape of the shield 9 comprises the means 6 to 8 provided on the other side (FIG. 5).
  • the shield 9 is also fed to the electrical connections 2, 5 and 4 by means of two conductor tracks 9 ′ and 9 ′′ formed from the lamination .
  • the second carrier element 10 is shown, which is also formed from a metal-clad polyimide substrate.
  • the means 11, 11 '; 12, 12 'and 13, 13' and on the other, unspecified surface side is one of the means 11, 11 '; 12, 12 'and 13, 13' are provided with appropriately designed shielding 14.
  • the shield 14 is connected to conductor connections 14 ′, 14 ′′ to electrical connections 2 ′ and 4 ′.
  • FIGS. 2 and 5 to 8 show the electrically conductive and insulating means 6, 6 'formed essentially from the metal lamination for better illustration. 7.7 '; 8.8 '; 9.9 ', 9''; 11.11 '; 12.12 '; 13,13 'and '14, 14', 14 '' shown hatched.
  • a film that is resistant to organic or inorganic media but in particular by applying a ketone liquid-resistant, preferably transparent film 5 ′′, 10 ′′ to the two carrier elements 5 and 10 of the first structural unit 25, the thickness in u-region on the respective surface of the individual carrier elements 5 and 10 provided, electrically conductive means isolated from each other.
  • the film 5 ′′ or 10 ′′ on both sides, the individual carrier element 5, 10 can be ver hermetically sealed closed unit to be trained.
  • the half of the second structural unit 45 shown in a sectional view in FIG. 2 shows the carrier element 40 formed from a substrate 40 ′′, which is provided on one surface side 40 ′ with a metal-clad polyimide film 42.
  • the deflection electrode 41 which is designed as a field section
  • the conductor track 41 ′ which is designed as a flag
  • the film 42 has the outer shape of the carrier element surface 40 'in the lower region and is somewhat wider on both sides than the conductor track 41' in the upper region.
  • a transparent polyimide film 42 ' which is electrically insulating the deflection electrode 41 and the conductor track 41' and which essentially has the outer shape of the first film 42, is also applied to the first film 42.
  • FIG. 4 schematically shows the carrier element 40 produced in sandwich construction in section along the line IV-IV and the substrate 40 ′′ and the polyimide film 42 applied thereon, the parts 41, 41 ′ and the second film can be seen 42 '.
  • the foils 42, 42 ' are shown in dashed lines in FIG.
  • the first carrier element 30 of the second structural unit 45 is designed analogously to the carrier element 40 described above.
  • the arrangement 50 which essentially consists of the two structural units 25 and 45, forms a unit, as shown in FIG. 1, and can be fastened to a support element (not shown) with relatively simple means.
  • the two charging electrodes 8, 13 and detection electrodes 7, 12 of the first assembly 25 and the deflection electrodes 41, 31 of the second assembly 45 are arranged in mirror image to one another.
  • the second structural unit 45 is offset in height from the first structural unit 25 such that the ink drop jet 65 emitted by the spray body 60 flies approximately in the middle region through the two deflection electrodes 31, 41 arranged in mirror image to one another and is deflected there.
  • the two support elements 5, 10 and the spacer 15 are by means of plated-through electrical connection points 1, 1 ; 2.2 '; 3, 3 'and 4, 4' are operatively connected to one another, electrical lines 16, 17, 17 'and 18 being supplied to the individual connection points, as shown schematically in FIG.

  • Ink droplets represented by lines 65 to 65 n are formed in the respective first building of the spray bodies 60 to 60 n charged and detected and deflected in the respective second structural unit onto an associated award carrier 90.
