Definitions

  • the invention relates to an ink jet print head of the type specified in the preamble of claim 1.
  • Such an ink jet printhead can be used in small, fast printers. These are used, for example, for franking machines for franking mail.
  • ink jet printheads are constructed according to the edge shooter or face shooter principle (First annual ink jet printing workshop, March 26-27, 1992, Royal Sonesta Hotel, Cambridge, Massachusetts). Efforts have been made to minimize the dimensions of the chambers to increase the nozzle density. The nozzle chambers have also been arranged in a concentrated manner towards the front edge. However, this principle only makes sense for inkjet modules with a few nozzles in a row and fails with a large number of nozzles.
  • a nozzle plate was then placed in front of a one-piece, multi-chamber ink jet printhead.
  • the chambers are no longer parallel to each other with the smaller chamber area, but now with the larger chamber area.
  • the piezo crystals form the chamber walls (shared wall concept, Ink Jet Printing Conference, November 11-13, 1991).
  • DE 34 45 761 A1 discloses a method for producing a transducer arrangement from a single plate of a transducer material. After coating the lower plate surface with a membrane layer, material is removed from the upper surface in order to produce separate areas which are arranged on the membrane above each pressure chamber (area 25.4 mm * 2.54 mm). This eliminates the need for an adhesive bond between the transducer material and the membrane and the uniformity of all distances is improved. The resulting nozzle spacing is, however, relatively large.
  • Such an offset arrangement of two rows of nozzles is also known for an edge shooter module - shown in FIG. 2 (First Annual Ink Jet Printing Workshop, March 26-27, 1992, Royal Sonesta Hotel, Cambridge, Massachusetts).
  • a module consists of a total of only three parts (glass pieces), a central part with openings and two side parts, each with a row of ink chambers and a row of nozzles on the front side of the respective side part.
  • the two rows of ink chambers and the rows of nozzles on the front of the respective side part are offset from one another, which again brings with it the disadvantages already mentioned when assembling the module and when actuating.
  • an ink jet print head having an in-line module with an edge ejection is proposed .
  • the invention is based on the fact that when the edges are ejected, the row of nozzles with a high number of nozzles can be accommodated in a side part of a module. For the first time, a higher nozzle density can be achieved in the manner according to the invention, completely independently of the dimensions of the ink chambers.
  • the dimensions of the ink chambers can now even be increased without reducing the nozzle density.
  • the ink jet print head is made up of several modules, only one of the modules carrying the row of nozzles or consisting of a multi-part module. It is furthermore provided that the end edge of the chamber-bearing part, which carries the row of nozzles, is arranged at the edge or in the middle of a module.
  • FIG. 1a The known principle of an edge shooter ink jet print head is shown in a perspective view in FIG. 1a shown. It consists of a module with two rows of nozzles offset from one another in the y direction. A first group 101 of ink chambers belongs to the nozzle group 1.1 of the first row and a group 102 of ink chambers to the nozzle group 1.2 of the second row.
  • FIG. 1b shows the known principle of a face shooter ink jet ink jet print head in a perspective view. It consists of a module, in the base of which two nozzle groups 1.1 and 1.2 offset in the z direction lie in a row. A group of ink chambers 101 and 102 for the nozzle group 1.1 and for the offset nozzle group 1.2 is supplied with ink from a suction chamber 151 and 152, respectively.
  • FIG. 1 c shows a perspective view of the principle according to the invention of an edge shooter ink jet in-line print head (ESIJIL). It consists of a module, on the end face of which k ⁇ 2 are horizontally offset nozzle groups 1.1, 1.2 etc. in a row.
  • the ink flow from the chamber groups 101-104 in the volume of the module is directed to the front edge of the first chamber-bearing part, which forms a side part of the module.
  • the chambers of a group 101-104 are staggered in the y direction and their associated outgoing ink channels are guided to the printing edge in such a way that they form nozzles 1.1-1.4 which are in a row but are nevertheless very close apart. This is achieved in FIG.
  • FIG. 2 The construction of a known two-row edge shooter ink jet module shown in FIG. 2 consists of 3 ceramic or glass parts.
  • a first part which bears a first chamber group on its left side, is connected via a middle part to a second part, which bears a second chamber group on its right side, in the y direction such that the chambers lie against the inside of the middle part and laterally to one another are offset (horizontally).
  • Each chamber is connected to a suction chamber via a first channel and to the front edge of the module via a second channel.
  • Each of the second channels forms a nozzle. It is relatively difficult to exactly maintain the distance between the two rows of nozzles.
  • the middle part has a first opening which connects the suction spaces of both outer parts to one another and to an ink supply opening. There are also openings for the fasteners.
  • An ink chamber group 101 and the suction chamber 15 are located on the left side of the first part 2, which is not visible in FIG. 3.
  • the part 4 containing the second chambers does not carry any nozzles but only the second ink chamber group 102, which passes through the second openings 14 of the middle part 3 is supplied with ink.
  • the associated further nozzles are connected to the ink chambers of the second part 4 via the third openings in the middle part 3.
  • Parts 2 - 4 are assembled in the direction of the y-axis.
  • the x-ray image of the ESIJIL printhead module according to the invention shown in FIG. 4 in plan view illustrates the in-line arrangement of the nozzles and the lateral offset of the ink chamber groups 101 of the first chamber-bearing part 2 and the group 102 of the second chamber-bearing part 4 the position of the first opening 18 in the middle part 3 to the ink supply opening 16 and the suction space 15, the second openings 14 which are in communication with the suction space 15 and the third openings 9 which supply the ink to the nozzles of the second nozzle group 1.2. It is contemplated that the nozzles of nozzle group 101 alternate with the nozzles of nozzle group 102 within the row of nozzles.
  • FIG. 5a A detail of the X-ray image from FIG. 4 is shown enlarged in FIG. 5a.
  • the chambers 11 of the first chamber group 101 located in the first part 2 are assigned nozzles of the first nozzle group 1.1 in the same part 2.
  • the chamber 11 is supplied with ink from a suction chamber 15 via one of the channels 13.
  • a corresponding section on the line AA through the drawing in Figure 5a is shown in Figure 5b.
  • the chambers 12 of the second chamber group 102 located in the second part 4 are assigned nozzles of the second nozzle group 1.2 in the other chambers 2, as shown in the section BB shown in FIG. 5c can be seen.
  • Ink flows from the suction chamber 15 located in the first chamber-bearing part 2 via another of the channels 13 and via one of the second openings 14 located in the middle part 3 into the chamber 12 of the second chamber-bearing part 4. From the chamber 12 to the corresponding one in the first Nozzle of the nozzle group 12 located in the chamber-bearing part 2 is connected via a third opening 9 in the middle part 3.

  • a respective second nozzle group 1.2 in the first part is connected to a chamber 12 of the second chamber group 102 in the second chamber-carrying part, which is arranged offset with respect to a chamber 11 of the first chamber group 101 of the first chamber-carrying part 2, the second chamber group 102 passing through Openings 14 in the center piece 3 is supplied with ink.
  • the middle piece 3 there are second openings 14 for supplying the second nozzle group 1. 2 with ink available.

  • the ink chambers 11, 12 are supplied in each of the first and second chamber-carrying parts from a common suction chamber 15 in the first chamber-carrying part.
  • the ink supply to the suction chamber 15 takes place via an opening 16 in that part 2, which forms a side part of the print head, and via corresponding openings 18, 22 in the respective center piece and further openings 17, 19, 21 in the parts 2, 4, 6 carrying the chambers and an opening 20 in the spacer 5.
  • a piezoelectric element 31 serves as a well-known means for driving ink out of a chamber and can be arranged on the chamber surface or in the chamber in order to exert pressure on the flexible chamber wall when it is excited To exert ink liquid in the chamber, causing an ink jet to emerge from the nozzle connected to the chamber.
  • Such a piezoelectric element 31 is arranged on the chamber surface in FIGS. 6b, 6c and 6d.
  • the chamber 12 is separated from the element 31 by a thin layer 30 consisting of the material of the chamber-bearing part 4, which is so elastic that the bending energy of the element 31 is only slightly damped.
  • a spacer 5 has a corresponding recess 32 for the piezoelectric element 31.
  • an elongated opening is provided in the chamber-carrying parts, which is connected to a correspondingly rotated 90 ° elongated opening in the middle parts and spacing parts.
  • An inkjet print head constructed from such individual modules has no tolerance problems when assembling.
  • the shape of the openings can be oval or an elongated hole, the small diameter of the openings determining the passage cross section for the ink flow. If there is a greater deviation from the round or rectangular cross section, the openings 9 and 10 can also be arranged in two rows on lines C-C and D-D.
  • a first module carrying the row of nozzles consisting of two chambers 2 and 4, the chamber groups 101 and 102 of which face a central part 3 and at least a second module consisting of two chambers 6 and 8 and a middle part 7 is constructed so that each module has a suction space 15, 25, that a spacing part 5 is present at least between the modules, which has an ink supply opening 20 and ink through openings 23, 26, which are assigned to the chambers of the second module, and a recess 32 for the means for ejecting 31 ink from a chamber, that the openings 23, 24 are connected to the third openings of the chamber-carrying parts and the middle parts in order to supply ink to the nozzles from the respective chambers, that the suction spaces 15, 25 each module via second openings 14, 24 with the chambers of the chamber groups 101, 102, 103, ..., 10k are connected to supply ink and that first openings 18, 22 are provided in each module in order to secure
  • the manufacturing process assumes that a module is composed of 3 parts each and is provided with piezoelectric elements and contacted.
  • a second module is joined together with the first module via a spacer 5 to form an ESIJIL printhead, the second module with parts 6, 7, 8 not having any nozzles, but only corresponding openings which correspond to the openings provided in parts 2 , 3, 4 of the first module are connected.
  • an ESIJIL printhead is built from a single, multi-part module.
  • FIG. 7a shows a front view with the in-line nozzle row and
  • FIG. 7b shows an X-ray image of the front view or an overlay of the sections through the lines C-C and E-E. All third openings lie on this line C-C. There are no further openings on a line D-D. It can be seen that the nozzle dimensions alone determine the maximum number of nozzles in the row. If there is a need for enlarged chamber dimensions, only the volume of the print head would have to be increased. Of course, it is also possible, if required, to solve higher tolerance requirements by means of the measures with third openings on a line D-D explained in FIG. 6.

Ink supply openings as well as second and third openings are worked out in the edge. After the piezoelectric elements have been worked out, they are contacted, wherein conductor tracks can also run on the chamber bottom and / or on the outside of the layer 30.
  • FIG. 8 shows the individual steps for a manufacturing process for the ESIJIL printhead according to the invention.

  • the parallel processing steps for several parts of a module include masking and subsequent Etching the through openings.
  • the duration of the etching bath determines the layer thickness of the removed material.
  • the old mask layer is removed by fine grinding the surface of the chamber parts. The surface is then masked in the areas that should not be deep-etched. After the etching of the ink chambers, the individual parts are finely ground to a final dimension and then masked to produce the supply channels and the ink nozzle channels, which should have a lower depth than the chambers. The material is removed again by etching. In special cases, only the etching sensitivity of the UV-irradiated areas of the material is used and a mask can be omitted.
  • etchants with different concentrations are used for the three areas in order to be able to remove the corresponding areas with different depth accuracy, the depth accuracy when etching the areas for through bores being lower than when etching very flat areas for the channels in the parts carrying the chambers and first the through holes, then the chambers and then the nozzle channels are etched. It is further contemplated that the thickness of the bottom layer 30 is monitored as the chambers are etched and that the thickness of the bottom layer 30 of the chambers required to complete the manufacture of the chambers is achieved by fine grinding each of the parts carrying the chambers.
