Definitions

  • the invention relates to a device for producing printing stencils according to the preamble of patent claim 1.
  • Such a device is already generally known and comprises a processing station known per se, the at least one bearing device for the front-side mounting of a hollow cylindrical screen, a drive device for rotating the screen about its cylinder axis, a processing table movable parallel to the cylinder axis and a control device for controlling the drive device, the transport of the processing table and for controlling a tool station arranged on the processing table.
  • the known device includes a laser for generating a laser beam with which an easily evaporable lacquer on the surface of the sieve can be thermally removed.
  • the invention has for its object to develop the device of the type mentioned in such a way that it has a simpler and less expensive structure, so that printing stencils can be produced more cheaply with it.
  • a device according to the invention for the production of printing stencils is characterized in that the tool station consists of at least one nozzle suitable for ejecting liquid.
  • This nozzle receives electrical ejection signals from the control device, in accordance with a predetermined pattern and in dependence on the rotational position of the screen cylinder and the position of the processing table.
  • the pattern or print pattern can be pre-stored in electronic form in an electronic memory of the control device be.
  • Each saved sample point is assigned a pair of values that contains the rotary position of the screen cylinder (angular position) and the axial position of the machining table. As soon as this pair of values is supplied to the control device by sensors, the assigned value of the pressure pattern is read out of the named electronic memory and used to form an ejection signal which is transmitted to the nozzle.
  • the control device outputs the electrical ejection signals to the respective nozzle located further back in the transport direction of the processing table in such a way that one and the same point on the screen surface the respective nozzles are sprayed one after the other.
  • a thicker covering layer can thus be produced in a simple manner, since one and the same point on the screen surface is coated several times, corresponding to the number of nozzles.
  • a plurality of liquids for forming the cover layer can be applied simultaneously to the sieve surface at the point mentioned, which can then react with one another to produce the cover layer.
  • epoxy resin components that are only converted into a gel state after they have been mixed together and the crosslinking reaction has begun.
  • the individual epoxy resin components are relatively thin, so that rapid droplet separation takes place within the nozzles and thus the nozzles can have a relatively short jet length.
  • these components are converted into a gel state as a result of the crosslinking reaction after striking the sieve surface, there is no danger that they will be thrown off the surface again. It is also advantageous to use the multiple components in that a better edge sharpness of the pattern is obtained.
  • the cover layer can also be formed by spraying on a viscous liquid which is, for example, an aqueous emulsion of a synthetic resin varnish or can be an aqueous suspension of pigments. It has proven to be advantageous to carry out the spraying on of the liquid accompanied by a laminar gas stream surrounding it, for example using an air or inert gas stream, in order to accelerate the drying process of the sprayed-on liquid.
  • the gas flow also prevents small secondary droplets from accumulating inside the nozzles and would otherwise contaminate them.
  • the speed of the laminar gas flow can also be selected so that liquid drops once formed can no longer approach each other on their way to the screen surface, as a result of which the formation of larger drops can be avoided.
  • the laminar gas flow can also be at an elevated temperature compared to the ambient temperature, as a result of which the drying of the ejected liquid can be accelerated even further.
  • the screen can also be heated at least at the point of impact of the liquid, for example by means of a heat radiator, in order to obtain a solid covering layer on the screen surface as quickly as possible. Warm air can also be blown axially into the interior of the sieve. Irradiation of the drops of liquid sprayed onto the sieve with ultraviolet (UV) radiation is also possible in order to start or accelerate the crosslinking reaction earlier, which leads to an even better edge definition of the pattern (UV curing). The short phase of viscosity reduction, which occurs during heating, is therefore avoided with a pure UV curing.
  • UV ultraviolet
  • FIG. 1 A first exemplary embodiment of a device according to the invention is shown in FIG. 1.
  • Reference number 1 denotes a rotating sieve in the shape of a cylinder, to which paint or varnish is applied as a covering liquid through one or more nozzles.
  • a jet 3 of the covering liquid sprayed out of the nozzles 2 is controlled by means of a computer 4 so that the covering liquid is applied to the sieve 1 only at those points at which the sieve 1 is covered due to the pattern must be and those parts of the sieve 1 remain uncovered where it should remain permeable.
  • the sieve 1 is received between two synchronously driven end heads 5 and set in rotating motion (direction of rotation D).
  • the right end head 5 can, for example, be displaced in the direction of the cylinder axis of the circular screen 1.
  • the sieve 1 is placed between the right and left end heads 5 and the right end head 5 is brought up to the sieve 1.
  • the screen 1, which is usually very thin and light, can possibly be set in rotation by the axially acting clamping force and the friction between the screen 1 and the left driven end head 5.
  • the rigidity of the screen 1 is always sufficient to notify the right end head 5 of the rotational movement via the acting frictional forces, if only the speed of the screen 1 is increased so slowly that the required acceleration torque does not overwhelm the transmission capacity of the circular screen 1.
  • Both end heads 5 are rotatably mounted on pedestals 6, the pedestals 6 being arranged on a machine bed 7. To guide the right pedestal 6 in Figure 1 guide rods 8 are available, the z. B. can be attached to the machine bed 7.
  • the left end head 5 is driven by a motor 9 and a belt 10.
  • This belt 10 spans a drive wheel 11 which is fixed on an axis 12 which carries the left end head 5.
  • an incremental pulse generator 13 which determines the rotational position of the axis 12 or the sieve 1 and outputs corresponding signals S D to the computer 4.
  • the nozzles 2, which are fastened on a processing table 14, are slowly advanced in the direction of the cylinder axis 1b of the sieve 1, so that a thin jet of droplet and consisting of masking liquid, which emerges from the nozzles 2, is very low along a helix Slope hits the sieve 1.
  • the feed table is impressed on the processing table 14 via a spindle 15, this spindle 15 being driven for this purpose via a stepper motor 16, which also receives its step signals S T from the computer 4.
  • step signals S T are converted into power pulses P T by a driver stage 17.
  • the rotation of the motor axis of the stepping motor 16 is transmitted to the spindle 15 via a belt 18 and a pulley 19. This extends through the processing table 14, which in turn is guided on guide rails 20 on the machine bed 7.
  • the nozzles 2 must be supplied with a covering liquid suitable for the subsequent printing process.
  • they are connected to small pressure vessels 21 via supply lines 22.
  • the covering liquid is under a slight excess pressure of approximately 1 to 5 bar.
  • a separate pressure vessel 21 will be provided for each nozzle 2, since differences in the line resistances and the need to be able to regulate the application quantity separately per nozzle 2 require different outlet pressures of the covering liquid.
  • Each nozzle 2 also has a not inconsiderable amount of unused covering liquid which has to be continuously sucked off and conveyed back.
  • vacuum tanks 23 are provided, into which the unused covering liquid is returned via return lines 24 due to the negative pressure prevailing in these tanks.
  • the recirculated cover liquid which has lost diluent as a result of the process which has passed through, can in turn be supplied to the application process as a cover liquid after preparation.
  • the nozzles 2 are arranged several times, in the present case twice. They are spaced apart from one another in the direction of the cylinder axis 1b or template axis in order to give the covering liquid time to dry at least slightly before the second application. This drying can be supported by blowing warm air, or by generating appropriate heat radiation.
  • a correspondingly designed heating device H can be mounted on the processing table 14.
  • the liquid can also be cured alone or additionally by UV radiation, as already mentioned, so that in this case there is also a UV light source (for example a mercury vapor lamp) on the processing table 14.
  • the nozzles 2 can also be displaced in the circumferential direction of the cylinder 1 or sieve, but this leads to a more difficult handling of the coating process if successive circular sieves 1 of different diameters are to be coated.
  • the nozzles 2 are preferably designed as electrostatic nozzles, each of which is supplied with a control signal S 1, S 2 from the computer 4 in order to inject the covering liquid when a control signal is received.
  • FIG. 2 shows a device that is basically the same as in FIG. 1, the same elements being provided with the same reference numerals.
  • the processing table 14 is mounted on a rear support wall 25 on guide rails 26 in the axial direction of the cylinder 1.
  • the spindle 15 and the stepping motor 16 with spindle drive 18 and 19 are also fastened to this rear guide wall 25.
  • the nozzle openings 28 point downward.
  • the covering liquid is applied in the finest drops in order to achieve a sufficiently high resolving power when generating the print pattern on the surface of the screen 1.
  • the liquid can have a high viscosity in order to be able to carry a sufficient proportion of solid substance with a relatively small droplet size.
  • several liquid components can also be sprayed on separately through different nozzles, which are combined at one point on the surface of the sieve 1. These can be different epoxy resin components which are only converted into a gel state when a crosslinking reaction has started after their meeting.
  • the method only makes sense if a very high drop frequency can be achieved.
  • electrostatically acting nozzles in which a liquid jet is regularly broken down into drops by a very high-frequency vibration, for example a pipe wall, and in which the drops are then electrically charged and deflected or, depending on the charge state, in an electrostatic field not be distracted.
  • nozzles of this type are not suitable for processing the highly viscous covering liquids required for coating screens.
  • FIG. 3 shows the structure of such an electrostatic nozzle 2.
  • the covering liquid which is supplied from the pressure containers 21 shown in FIG. 1, is under excess pressure. From there it exits continuously through a bore 30.
  • a thin needle 31 which is excited by ultrasound to produce high-frequency vibration in the longitudinal direction of the needle, provides regular disturbances in the annular flow channel formed by the needle 31 and the bore 30.
  • the oscillatory movement of the needle 31 also prevents the bore 30 from becoming blocked, for example. B. by small particles.
  • a ring electrode 33 is provided, which is kept small in diameter, because sufficient charging of the drops can then be achieved even at low voltages.
  • the aim is to be able to work with a voltage of 100 - 200 V. This voltage must be present at the ring electrode 33 at the moment the drop breaks off. Voltages of this size can still be conveniently switched at high frequencies using transistors.
  • the drop At the time the drop is torn off from the still connected jet, it must be kept at a zero voltage potential with respect to the ring electrode 33, so that a negative charge remains on the tearing drop, and the tear must also take place in the area of the ring electrode 33.
  • the ring electrode 33 is kept small in diameter, whereby high field strengths are achieved even at lower switching voltages.
  • the charged liquid drops which here have the reference numeral 34, are then guided into a catcher 37 by the action of a direct voltage field applied via an electrode 35 on a curved path 36. From there they arrive via the return lines 24 mentioned in FIG. 1 into the vacuum tanks 23 which are also shown there.
  • the uncharged liquid drops 38 are not deflected by this DC voltage field and accordingly continue their path almost linearly along the railway line 39 in order to finally reach the sieve 1 hold true.
  • the screen 1 here has one to the web 39 on this impinging, uncharged drops 38 vertical position. However, it may well be expedient to incline this sieve 1 in relation to such a position, which is shown in connection with the next FIG. 4.
  • the covering liquid must transport solids to a sufficient extent in order to form a well covering film after drying on the sieve 1, as a result of which a high viscosity is required.
  • the high viscosity helps, however, that after the covering liquid has been applied to the sieve 1, it remains at the impact point despite the centrifugal force acting on it and does not shoot through the perforation of the sieve due to the high impact speed or sprayed into even smaller droplets during the impact on the sieve 1.
  • a combined liquid and air or inert gas supply is carried out in the area of the ring electrode 33.
  • liquid is first introduced through holes 40 in order to clean the ring electrode 33. It is then blown dry through the same holes 40, for example through dry, heated air or an inert gas.
  • the same configuration of the nozzle is additionally used to prevent the thin bore 30 from drying out during longer work breaks. In this case, the adjacent air space 41 in front of the bore 30 and inside the ring electrode 33 is filled with flushing liquid through the bores 40.
  • This rinsing liquid is kept under a very slight excess pressure (approximately 10 to 20 mm water column), as a result of which a liquid meniscus 43 is formed within the nozzle channel 42, which can persist for a long time and which prevents liquid from escaping from the nozzle channel 42.
  • This filling protects the thin bore 30 from drying out.
  • a conical countersink 44 can be provided in order to allow the liquid as good an access to the bore 30 as possible. Through them, the bore 30 opens into the nozzle channel 42 in the direction of the ring electrode 33. However, it may also be expedient not to let the rinsing liquid come into contact with the covering liquid within the bore 30 in order not to dilute the latter.
  • the conical countersink 44 is omitted, and there is only a correspondingly small cylindrical drilling attachment at this point.
  • the flushing liquid will then also form a meniscus in this hole, similar to meniscus 43.
  • the covering liquid at the exit of the hole 30 also forms a meniscus.
  • FIG. 4 shows the overall structure of the nozzle according to FIG. 3.
  • the following apply the same reference numerals as in Figure 3.
  • the direction of impact of the drops 38 on the screen 1 is no longer vertical here, but is at an angle 45. This helps to prevent the drops from passing through the screen 1, because then before each Drop in the direction of its trajectory is always a material wall. In addition, there is a reduced relative speed between the drops and the sieve, which also reduces the risk of the drops bursting.
  • the needle 31 is held in a needle holder 46 which is designed as a step horn, ie the diameter of the needle holder 46 decreases towards the tip of the needle 31.
  • the needle holder 46 is firmly held in a membrane 47 and this is excited by a piezo element 48 to the high-frequency vibration.
  • a pressure piece 49 transmits this vibration to the membrane 47, whereby the liquid in the pressure chamber 29 is also pressurized by the membrane 47 itself.
  • the supply lines to the pressure chamber 29 must be designed to be correspondingly thin. With a corresponding design of the pressure piece 49, a pre-amplification of the vibration amplitude can be achieved mechanically.
  • the piezo element 48 is excited by supply lines (no longer shown) with a high-frequency sine or square wave voltage corresponding to the natural frequency of the nozzle arrangement. Since the piezo element 48 is composed of a large number of thin layers in a sandwich-like manner, even low electrical voltages are sufficient to produce violent contractions or elongations, in particular in the region of the natural frequency of the overall arrangement.
  • the piezo element 48 is statically prestressed in its longitudinal direction by a pressure screw 50, and a counter nut 51 secures this screw setting.
  • a housing 52 statically and dynamically closes the power flow of all individual components.
  • the bore 30 of the nozzle 2 is made in a sapphire plate 53, which is pressed by a screw 54 into a holder 55 and is fixed there in this way.
  • the choice of the sapphire bore material largely reduces the risk of the needle 31, which is made of a metallic material, from rubbing or welding to the bore wall due to the needle vibration.

  • the needle 31 therefore only extends to the vicinity of the narrowest bore point.
  • the action of the needle 31 is similar to the action that was described earlier.
  • An oscillating movement of the needle 31 in the direction of the nozzle outlet increases the pressure in the nozzle interior 57 both because of the wall thrust forces and because of the displacement effect of the needle end face 32.
  • the corresponding return movement of the needle 31 causes a pressure reduction.
  • the formation of the individual drops takes place in the area of the ring electrode 33, which here too is provided with a suitable supply line for applying an electrostatic potential.
