  • the invention relates to a method for producing printed structures, a screen printing machine, a screen printing squeegee and a surface printed with structures.
  • Screen printing processes or screen printing machines in which flowable material is brought to a surface through openings in a printing screen have long been known.
  • the invention proposes on the one hand a method for producing printed structures on surfaces by means of screen printing, in which a squeegee prints printing material through a screen onto the surface, which is characterized in that after a first print, at which a first structure is applied, a second printing, in which a second structure is applied, is carried out and the second structure is at least partially applied over the first structure.
  • the printing squeegee should be guided over the screen at a greater distance from the surface during the second printing than is done during the first printing.
  • the screen can have a larger jump in terms of the surface during the second printing than is the case during the first printing.
  • jump denotes the distance between the screen or a screen frame and the surface to be printed or and a printing table.
  • the invention also proposes a screen printing machine which is characterized by means for spacing a squeegee at variable intervals during a printing process.
  • the screen printing machine can also have means for fixing a variable len jump during a printing process include. It goes without saying that this variability is generally not used to change the jump or the distances while the squeegee sweeps over the screen. Rather, the screen printing machine according to the invention should be able to ensure different distances between the printing material and the printing squeegee or screen between two different printing processes.
  • the screen printing machine according to the invention with the means described above is able to adjust these distances or the jump to change quickly and with maximum precision between two different printing processes. This can also be done, for example, by changing appropriate stops or systems.
  • the spacing means or fixing means described above are preferably electrically driven.
  • the method according to the invention and the screen printing machine according to the invention thus enable a multi-layer structure of a structure printed on a surface. This ensures that the structure that has already been printed is not destroyed by the subsequent printing process. Sufficiently sensitive printing materials can therefore also be used.
  • Such a structure makes it possible lent to manufacture even the smallest structures with the necessary profiling. While it is already possible according to the prior art to produce fine conductors of, for example, 30 ⁇ m to 80 ⁇ m, which are only a few ⁇ m thick, the layer structure according to the invention enables structures to be produced whose thickness exceeds the width of these structures. In particular, this makes it possible to provide structures which have at least one region which is less than 100 ⁇ m wide and more than 30 ⁇ m thick.
  • structures over 50 ⁇ m can also be built up.
  • conductor tracks that are relatively narrow and yet have a low resistance due to their height can be provided.
  • these layer arrangements can be used in solar technology, in monitors, in other applications in the field of electronics or for the construction of porous structures, as described for example in EP 0 627 963 B1.
  • At least two of the layers that are arranged one above the other perpendicular to the surface should be thicker than 1 ⁇ m, preferably larger than 10 ⁇ m, in particular larger than 15 ⁇ m.
  • Pasty materials are particularly suitable as materials for the printing according to the invention. Depending on the structure or properties of the surface and the desired structure, it can be advantageous to work with different pastes. A foundation paste can be applied in a first printing process ensures sufficient adhesion to the surface, while a build-up paste is then used.
  • a screen printing machine which has a device for checking the relative position between the screen and the printed structure.
  • this is a camera system which is placed between the screen and the printed matter and compares the position of a registration mark on the screen and the position of its printed image on the printed good.
  • the known arrangements are only suitable for relatively small-area printed matter. For this reason, it is proposed according to the invention that a screen printing machine has two such devices, which are preferably provided on different sides of the screen.
  • a wear control can also be carried out, particularly with regard to the screen.
  • a screen tends to sag further, which means that from a certain point of time sufficient printing precision can no longer be guaranteed.
  • these devices for checking the relative position can of course also be used to check the position of the printed matter or the surface before a second print.
  • Pre-positioning is preferably carried out to ⁇ 100 ⁇ m.
  • the pre-positioning can preferably be done by placing the printed material on the printing plate. This can be ensured, for example, by means of suitable supply devices.
  • Fine positioning is preferably made possible by positioning the printing plate using appropriate fine positioning means. The latter works preferably with an accuracy between 0.1 and 10, in particular around 1.5, ⁇ m.
  • Such a procedure also makes it possible, with a suitable design, to allow a small field of view for the devices for checking the relative position, namely only for fine positioning, as a result of which the latter can be designed more precisely in their position measurement.
  • the screen printing machine have means for compensating for a bending of the printing doctor. This proves to be advantageous, particularly in the case of larger screen printing machines, regardless of the other features of the same.
  • means are advantageously provided for measuring a deflection of the printing doctor.
  • Such measuring means can be provided on the one hand directly on the printing squeegee, a printing squeegee holder, a traverse or the screen printing machine.
  • an online Measurement conceivable.
  • the printed image itself can also be checked, in particular if the printed matter is removed under the screen between two printing processes, in order to determine a deflection of the printing squeegee. This can be achieved in particular in connection with the relatively strong printing structures according to the invention with relatively little effort, especially since a pressure check is often carried out in such printing processes anyway.
  • Such a measurement of the doctor blade deflection is also advantageous regardless of the other features of the present invention.
  • such a deflection measurement can also be used as a wear control.
  • the screen printing machine can have a control circuit, according to which a deflection of the squeegee is measured and then compensated for using suitable compensation means.
  • the screen printing process according to the invention must have an extraordinarily high precision.
  • a precise monitoring of the squeegee ensures a relatively high level of precision in this regard.
  • a screen printing squeegee is proposed according to the invention, which is characterized in that it is firmly connected to an identifier.
  • the identifier be designed to be machine-readable.
  • the screen printing machine can have means for storing the squeegee data, such as an identifier, the squeegee strength, a grinding strength, a deflection and the like, so that the machine selects suitable machine parameters, such as compensation, depending on the printing squeegee currently in use. Accordingly, it is advantageous if the screen printing machine has means that can read out a screen printing squeegee identifier directly.
  • identifiers or such a storage of doctor blade data can also advantageously be used independently of the other features of the present invention to improve the print quality in screen printing.
  • the squeegees are subject to a certain amount of wear. This can be countered, among other things, by regularly sanding or replacing a doctor blade.
  • a screen printing machine is proposed in which a squeegee attachment for attaching the printing squeegee to the screen printing machine comprises means for centering the printing squeegee.
  • the centering also ensures that a squeegee, after being used repeatedly, is fastened in an identical position with respect to the screen printing machine. In this way, the precision of the screen printing machine can be increased considerably. In general, this also applies independently of the other features of the present invention, but is particularly advantageous in connection with the previously described storage of the doctor blade data.
  • the centering means are preferably designed to be self-centering, so that the risk of operating errors is reduced in this regard.
  • the centering means can comprise a clamping device for clamping the printing squeegee to the screen printing machine so that the centering process and the fixing of the printing squeegee on the screen printing machine can be carried out in one operation.
  • a doctor blade change can be carried out relatively quickly and reliably.
  • the doctor blade preferably comprises a doctor blade holder and a corresponding doctor blade rubber connected to this doctor blade holder.
  • identifiers or the like can also be provided on the doctor blade holder.
  • the squeegee holder thus enables simple handling of the otherwise relatively sensitive squeegee rubber as well as relatively uncomplicated fastening of the squeegee rubber with respect to the screen printing machine.
  • the doctor blade holder can have at least one holding strip or at least one holding recess which extends in the longitudinal direction of the printing doctor blade. If a corresponding clamping device engages in such a holding recess or a corresponding clamping device engages around such a holding strip, a stable and centered fastening can be realized particularly easily.
  • At least the squeegee holder or the corresponding holding device of a squeegee traverse preferably has a prismatic area, in which a corresponding counterpart, for example a curved area, is centered.
  • the centering device can be designed to be effective over more than 90% of the printing squeegee length.
  • the centering device is preferably effective over the entire length of the squeegee. If the clamping device or the centering device is designed in such a way that the pressure doctor blade can be inserted in the unclamped state in such a way that it is held by the clamping device or the centering device, a doctor blade change is made considerably easier. When a doctor blade is removed, the clamping device or the centering device can then be opened and the pressure doctor blade, which is now held loosely, can be removed. Likewise, when the pressure doctor blade is inserted, it can be inserted into the clamping device or into the centering device in such a way that it is held by the latter, and then clamped or centered.
  • Such a construction is structurally relatively simple if the clamping device has at least one holding shoulder projecting into the clamping area. A corresponding holding area of the printing squeegee can then be placed on such a shoulder before clamping.
  • a holding shoulder is also advantageous, regardless of the other features of the present invention.
  • the throughput speed in such a printing process can be increased if the printing squeegee is placed directly on the surface to be printed at the start of the printing process. Likewise, the printing squeegee can be lifted off the printed surface immediately after the printing process. In the case of such a procedure, a mask surrounding the printed material, on which the printing squeegee is placed or from which the printing squeegee is lifted off, can be dispensed with.
  • the time saved as a result has an effect, in particular especially with large quantities, very significantly on the throughput.
  • the overall handling for the screen printing machine is easier if such a mask can be dispensed with.

  • the printing squeegee is preferably placed on the surface to be printed with a speed component oriented parallel to the surface, or is lifted off the surface to be printed. In this way, the printing process is started immediately with the touchdown, which leads to further time savings. In addition, the print image improves because the squeegee sweeps over the surface or over the screen at a more uniform speed.
  • the procedure described above can in particular be carried out with a screen printing machine which has means for ensuring a constant functional dependency between the horizontal and the vertical squeegee movement at least during one movement section.
  • This movement section is preferably the placement and / or lifting of the squeegee.
  • the constant functional dependency between the horizontal and the vertical squeegee movement can easily ensure that the squeegee touches or is lifted off from such an edge with a certain speed component directed parallel to the surface at the respective edge of the surface to be printed becomes.
  • the constant, functional dependency is preferably selected in such a way that the printing squeegee is accelerated as slowly and uniformly as possible both in the horizontal and in the vertical direction, so that the screen printing machine operates with relatively little vibration even with larger masses moved with the printing squeegee.
