Definitions

  • the invention relates to a method and a device for laying wires on a plastic substrate, having the features of the preamble of claim 1. It also relates to a device that is particularly suitable for carrying out the method .
  • window panes for vehicles or buildings heaters, antennas, decorations or also anti-radiation screens which are essentially formed of electrically conductive wires, which are mechanically deposited on an adhesive layer of the laminated pane according to a predetermined pattern.
  • both ends are generally provided with collecting conductors, which are electrically connected to all the wires. by soldering, by electrically conductive adhesives or the like.
  • US-A-5 891 280 discloses a method of laying thin threads and the corresponding device, with which the threads are laid on an adhesive film or the like.
  • the method is characterized in that the films to be lined are fixed on a rotating drum, which serves for the positioning of the films under a laying unit, which is movable in a reciprocal movement parallel to the axis of the rotary drum, with a large positioning accuracy in the manner of a drawing table.
  • the wires can in principle be deposited on tracks in any case, in particular also curves, and their mutual spacings need not necessarily remain constant. The direction and speed of rotation of the drum, however, remain constant.
  • the laying unit is moved in a reciprocal movement by means of a longitudinal spindle drive, which allows precise positioning, but which is in principle relatively slow in the case of large movements.
  • the method can also be used to connect yet collector conductors on the drum with the wires, and to cut them.
  • An older device known from DE-A1-42 01 620, for laying fine wires on a thermoplastic film comprises one or more laying units which can / can be moved again in the direction of the The axis of a rotating drum carrying the film, in which, however, the yarns are finally wound helically around the drum. In the finished product, this is not a problem because of the very low angle of inclination between the wires laid at very short distances from one another. This process works in the end faster than the technique mentioned above, but it does not allow the laying of son following a contour.
  • the two types of known devices have in common that the films are fixed on the drums by the application of a pressure difference; the side surfaces of the drums are perforated, and the pressure in the interior space of the hollow drum is reduced with respect to the atmospheric pressure by an air suction.
  • EP-B1-613 769 discloses a method for cutting heating wires deposited continuously on a substrate
  • EP-B1-656 257 discloses a method for electrically contacting the heating arranged parallel to each other with collector conductors oriented transversely to them.
  • the object of the invention is to provide a method which brings together the advantages of the known devices, which in particular allows a high speed of laying while following patterns in a flexible manner, and of proposing a device which is particularly suitable for the implementation of the invention. process.
  • a particular characteristic of this process according to the invention consists in that the support is now reversible (with reversal of the direction of advance or rotation) and also that it is driven with an adjustable speed.
  • possibilities are clearly widened, on the one hand for laying the wires on the substrate, and on the other hand for the use of other tools.
  • a flat or curved support with a mass as small as possible can be used which can be driven and positioned very precisely with the aid of a positioning drive, preferably a direct drive without play with very short reaction.
  • Such direct trainings are in themselves known. It is not absolutely necessary that they be operated electrically, but one can also use hydraulic or pneumatic positioning drives.
  • This first step according to the invention is completed by the use of a linear drive fast and precise, preferably electric, for the movements of the tools transversely to the direction of movement of the support.
  • a linear drive fast and precise, preferably electric, for the movements of the tools transversely to the direction of movement of the support.
  • at least one guide rail is required with the driving magnets and at least one slider serving as a tool carrier or as configured as such.
  • fluid-driven servomotors pneumatic or hydraulic
  • linear motors which can, with their control members, each time position a tool or several tools in a synchronous manner and parallel to each other. In this way, it is possible to achieve high adjustment speeds and precise positioning.
  • the complete control of the machine can be programmed, so that, to change a laying pattern, only the current control program must be modified.
  • the waviness amplitude of the laid wires may finally be variable. It is certainly known in itself to lay the son in corrugated lines, however it is obtained with the known means (in which the son are deformed plastically between two toothed wheels in engagement immediately before laying on the substrate) only a uniform corrugation, even if it is visually very unclear and the wires are well hidden from view.
  • the corresponding devices make it possible, by a suitably coordinated control of the advances of the laying units and the support, to lay the wires also in waves with variable wavelengths and / or amplitudes. .
  • a wire which must pass only a relatively short distance between the collecting conductors in the case of a predetermined window contour, can acquire by a suitable corrugation (with a longer effective wire length as a result) a active resistance which is equal to the resistances of the "longer" wires visually mounted electrically in parallel, or in any case at least close to them.
  • This request can be met by replacing the mechanical drive of the known laying units, for example by stepping motors or other suitable servocontrols.
  • the control of these drives / stepper motors is naturally synchronized with the control of the support. This produces a variable electronic distribution.
  • the Z axis of the movement of the tools can be set in translation or in rotation.
  • it can for example be provided a hollow shaft electric drive, which can first be moved and positioned along a rectilinear guide, and which can pivot about this axis in translation or an axis parallel thereto for the action of a tool that it carries, for example a cutting tool or marking.
  • Cutting tools can be integrated in the device both for the lengthening of the laid wires themselves (clamps, short circuit electrodes) and for cutting the substrate, for example a thermoplastic adhesive film (knife) , and be controlled with the process according to the invention. It is also possible, for example, to combine a laying unit with a cutting tool, so that after the laying of a defined length of wire, it is immediately cut conveniently before starting the laying of the wire. next (possibly neighbor). In this case, it would also be possible, unlike the known methods and devices, to pose in opposite directions of installation of the wires to be laid one after the other.
  • a rotary drum-shaped support 1 is provided with a reversible electric direct drive 2, which acts on an axis of rotation 3 of the support 1 fixedly mounted in a frame and which can, on the one hand, drive this one around this axis of rotation 3 in both directions of rotation and on the other hand to control and position it in predetermined movement patterns.
  • a plastic substrate 4 is fixed on the surface of the support 1 with adequate means (of a known nature).
  • two laying units 5 of the same type have been indicated. They are intended to lay thin wires 6 on the plastic substrate 4. They are fixed on sliders 7, which can slide along guide rails 8 fixed to the frame, perpendicular to the plane of the drawing.
  • FIG. 8 It is further shown schematically another tool 5 'on the left side, next to the support.
  • This is guided on a cylindrical guide rail 8 ', and its slider 7' has a bore adapted to the guide rail 8 '.
  • This slider can not only slide along the guide rail 8 ', but it can also pivot around it (hollow shaft pivot drive), so that the corresponding tool 5' can also perform a movement of lifting (pivoting) around it with respect to the support 1 and the plastic substrate. It is thus adjustable back and forth between a rest position (raised, drawn in solid lines) and a working position (in contact with the plastic substrate, drawn in phantom).
  • the tool may for example be a heating tool, a cutting tool and / or a writing tool and it then comes into contact with the plastic substrate only when its function is really necessary.
  • the laying units 5 can also be adjustable in height relative to their slider 7, in particular to bring them with their blocks 9 in the exactly correct position above the surface of the substrate, and further to facilitate the exchange of wire coils and insertion of new wires 6.
  • FIG. 2 further illustrates the relative mobility of the laying units 5 and the support 1 with the plastic substrate 4.
  • a guide rail 8 This, however, outside the laying unit 5, in addition to the slider 7 two more sliders 7 drawn in phantom with other tools of the type described above.
  • the guide rail 8 extends parallel to the axis 3 and therefore perpendicular to the actual working direction of the support 1.
  • a programmable control unit C which coordinates the movements of the support 1 and sliders 7 with the installation units and the other tools. It is symbolically connected using control and power lines with the direct drive and the guide rail respectively with the sliders associated with it.
  • the laying units 5 are suitable for laying the wires 6 in the correct and safe position, independently of the direction of the relative movement between the support on the one hand and the sliders on the other hand. This is reproduced here in a very simplified way because the son 6 are guided by a block 9, whose lower face is placed as close as possible to the surface of the plastic substrate 4.
  • the plastic substrate 4 is here divided into three sections along the width of the support 1 by two pairs of phantom lines drawn vertically.
  • Sinuous paths are possible, if one uses the option of the direct drive 2 to move in oscillation back and forth the support 1 itself (also indicated on the left by a double arrow) and to continue at the same time the laying of a wire 6.
  • This variant is illustrated in the central portion of the plastic substrate 4, where is produced on the edge thereof with the wire 6 a corrugated pattern propagating parallel to the axis 3 support 1, only by the oscillation of the support 1 and at the same time the translational movement of a slider 7 carrying a laying unit in addition to the block 9.
  • a cutting line 10 which is made here with the help of another slider 7 equipped with a cutting tool 5 ', for dividing the substrate of material plastic 4.
