Definitions

  • the invention relates to a piezoelectrically operated writing head for ink mosaic writing devices with writing nozzles in the form of ink channels receiving writing liquid, from which the writing liquid is ejected dropwise by piezoelectric deformation of a drive element.
  • the writing head consists of a perforated matrix with a row of nozzles, in front of the inlet opening of which rod-shaped piezoelectric elements are arranged in such a way that the 'piezo elements bend when a voltage is applied and thereby drop-wise write liquid ejects from the corresponding nozzle (DE-PS 25 27 647).
  • the individual rod-shaped piezoelectric elements are combined to form a kind of comb and thus connected to one another via a common web.
  • Great demands must be made of the manufacture of the comb and of the perforated die, particularly with regard to the tolerances, in order to ensure that the print head functions properly. For the same reason, the die matrix and comb must be carefully adjusted.
  • write heads consist of a single casting process made of dielectric plastic manufactured workpiece consist, which contains several channels receiving the writing fluid (DE-PS 25 43 451). These channels are also closed off by a perforated matrix towards the recording medium. Ceramic tubes, which enclose the actual ink channels in a cylindrical shape, serve as the piezoelectric drive elements. In order that the outlet openings can be arranged so close to one another that the desired high recording quality is obtained, the ink channels are directed away from these outlet openings in a radial manner and the piezoceramic tubes are arranged at a distance from the outlet openings.
  • This write head is relatively complex to manufacture and also has a large mass, so that correspondingly large acceleration forces are necessary for the rapid deflection of such a write head.
  • the object of the present invention is to design the write head mentioned at the outset in a mechanically stable manner and, moreover, to significantly simplify production.
  • efforts are also being made to keep the mass to be accelerated as small as possible.
  • the ink channels are formed by a channel matrix, which consist of a series of strips of piezoelectric material which are arranged in parallel at a distance from one another, electrically contacted on both sides and covered on both sides by a plate.
  • a channel matrix which consist of a series of strips of piezoelectric material which are arranged in parallel at a distance from one another, electrically contacted on both sides and covered on both sides by a plate.
  • the strips are formed, for example, by sawing grooves into a solid plate made of piezoelectric material, which is then only on the top be covered with a plate to form the duct matrix. The rest of the solid plate remains the lower plate. In this way, rectangular channels for the ink are created between the strips of piezoelectric material.
  • the dimensions of the strips and the spaces can advantageously be chosen so that the channels formed between the strips form the writing nozzles directly.
  • a separate piercing die dispensed Anlagen can in this case therefore eliminates the otherwise complicated adjustment between perforated die and piezo - comb or between perforated die and the workpiece with the ink channels.
  • the channel matrix according to the invention is mechanically robust and nevertheless small and light, so that an extremely high deflection speed of the print head is possible with reasonable forces.
  • the liquid contained in the channels is ejected uniformly in both directions from these, tests have shown that a sufficiently large ejection takes place in the direction of a recording medium arranged in front of the write head. Since the Ink channels on the back are connected directly to a storage chamber for writing liquid, the sudden change in cross-section causes a reflection of the liquid wave running in this direction, so that the majority of the displaced liquid is ejected in the direction of the recording medium.
  • the strips of piezoelectric material are rigidly connected to a carrier plate, it is particularly advantageous if this carrier plate is kept so thin that the longitudinal expansion of the piezoelectric strips does not cause the carrier plate and thus the entire channel matrix to bend. Particularly favorable mechanical properties are obtained if the strips are additionally reinforced on the upper side by a layer - in particular made of metal - which offers approximately the same resistance to the longitudinal expansion as the lower carrier plate.
  • the carrier plate is made directly of metal, it can be used as a common electrode for all strips of piezoelectric material.
  • the channel matrix is particularly simple to manufacture if a bilaminar material made of carrier material and piezoelectric material is used and the strip structure is produced, for example, by sawing in the piezoelectric material. After the corresponding contact of the strips on the top, only a cover plate is applied as a finish. Every second channel can in turn be filled with an elastic material or air.
  • Another particularly advantageous production of the print head is based on a laminate of piezoelectric material provided on both sides with a metal layer, from which longitudinal channels are worked out alternately from one side and from the other.
  • the depth of the channels extends approximately over a metal layer and the piezoelectric material.
  • the channel plate produced in this way is closed off at least on one side with a continuous plate.
  • This construction also has the advantage that the channel plate can be intentionally broken in the longitudinal direction by different layers, so that the tensile stress that occurs when a voltage is applied can no longer spread. Nevertheless, the mechanical stability of the entire arrangement is completely preserved.
  • the outer basic structure of an ink mosaic writing device can be seen from FIG.
  • the recording medium 3, for example normal registration paper, is pulled past the front face 6 of the housing 7 in the direction of arrow 4 via transport rollers 1 and 2.
  • the connecting line 8 is guided, which is provided at its free end with a plug 9 for connection to a corresponding control device which receives the control signals for recording the desired courses, characters or Supplies images.
  • the housing 7 contains the actual write head, of which a possible embodiment is shown in perspective in FIG.
  • the writing head consists of a channel matrix 10 and a reservoir 11 for writing liquid 12.
  • ink channels 13 to 16 are indicated by dashed lines, which are formed by two plates 17 and 18 and the strips 20 to 27 between them made of piezoelectric material.
  • the electrical contacting of the piezoelectric strips has been omitted here.
  • the plate 17 can be made of metal and form a common electrode for all common strips 20 to 27 made of piezoelectric material. The other side of the strips must then be contacted in pairs. If the plate 18 is also made of conductive material, insulation must be provided between it and the contacts.
  • FIG. 3 shows a cross section through the channel matrix corresponding to FIG. 2.
  • a nickel foil is used as the carrier plate 17, for example.
  • the piezoelectric material 20 to 27 is applied in strips. These strips are provided in pairs with electrical contacts 30 to 33.
  • the end is formed by the end plate 18, which in this case should consist of a non-conductive material.
  • this representation indicates that every second channel 34 to 36 formed is filled with an elastic material, for example silicone rubber. Assuming, for example, that the width of the piezoelectric strips is 50 ⁇ m and the distance between the adjacent strips is the same, one obtains a distance of the writing nozzles (cannula 13 to 16) of 200 ⁇ m. This means that five writing nozzles per mm are provided, with which very good recording quality can already be achieved.
  • the thickness of the strips can be of the same order of magnitude.
  • the length of the channel matrix can be approximately 10 mm.
  • the thickness of the carrier plate 17 and the cover plate 18 is approximately 20 ⁇ m.
  • FIG. 4 shows an enlarged section of the representation according to FIG. 3 in two different states.
  • the state in which a voltage is applied to the contacts to the two strips 20 and 21 made of piezoelectric material is represented by solid lines, so that these strips become narrower and higher.
  • the state in which the strips of piezoelectric material have returned to their original shape is shown in dashed lines.
  • the cross-sectional area of the channel is enlarged and in this way additional writing liquid is sucked into the channel.
  • Short-circuiting the voltage returns the strips to their original shape and thereby reduces the enclosed channel volume in such a way that the writing fluid to be displaced is ejected as drops at the front of the channel matrix.
  • FIG. 5 again shows in cross section a further embodiment of a channel die 40.
  • This essentially consists of a laminate made of piezoelectric material 41, which is provided on both sides with a metal layer 42 or 43. Alternating from the top and Channels 44 to 47 are introduced into the bottom of this laminate, for example by sawing.
  • the channels each extend over a metal layer and the layer made of piezoelectric material. It should be pointed out at this point that these channels do not necessarily have to pass through the entire layer of piezoelectric material. Every second channel can in turn contain air and be sealed off from the storage chamber.
  • the strips of piezoelectric material By preventing the strips of piezoelectric material from expanding in the longitudinal direction by means of reinforcement on the top of these strips, the strips become practically narrower than usual when a voltage is applied. In this way, an approximately 30 percent stronger effect can be achieved with the same achieve the applied voltage. In other words, the same effect can be achieved with a reduced voltage and thus overall with a reduced power to be applied.
  • Another advantage of the channel matrix according to the exemplary embodiment according to FIG. 5 is that the tensile stress in the longitudinal direction caused by the deformation of the strips of piezoelectric material can be suppressed by intentionally breaking the piezoelectric material several times in the longitudinal direction.
  • the fine transverse cracks that occur do not change the mechanical stability of the entire channel matrix, but the tensile stresses can no longer spread in the longitudinal direction.
  • FIG. 6 it is again shown in a schematic cross-sectional representation that two channel matrices 50 and 60 can be arranged tightly packed in order to increase the resolution, for example.
  • two channel matrices 50 and 60 have been assumed. This should not preclude the fact that a plurality of such single-row channel matrices can be combined to form a block if necessary.
  • the middle plate 51 is simultaneously used as a cover plate for the upper and lower row of channels. If one thinks of this plate 51 again from a conductive material, this results in a common electrode for both the upper and the lower strips made of piezoelectric material.
  • FIG. 6 it is again shown in a schematic cross-sectional representation that two channel matrices 50 and 60 can be arranged tightly packed in order to increase the resolution, for example.
  • the middle plate 51 is simultaneously used as a cover plate for the upper and lower row of channels. If one thinks of this plate 51 again from a conductive material, this results in a common electrode for both the upper and the lower strips made of pie
  • FIG. 7 shows an ink channel 70 in longitudinal section.
  • a part of the piezoelectric material 73 can be seen in the right end region, which reduces the height of the outlet opening.
  • the ink channel 70 has a larger volume and, as a result, a larger ink output without the size of the drops changing. Since only the height of the ink channels has been changed, the mutual distance can still correspond to the required resolution.
  • FIG. 8 shows a writing head 80. Similar to that shown in FIG. 2, only that four channel matrices 81-84 are provided densely packed and also four separate storage chambers 85-88 for writing liquid of different colors. If you choose colors, red, blue, yellow and black, you can use it to create flawless color recordings - controlled e.g. from a still image monitor.
