Definitions
- the invention relates to a method and a device for producing a screen printing stencil.
- Screen printing stencils are either created galvanoplastic or so-called lacquer stencils are produced.
- an already permeable fabric e.g. a perforated film or stencil gauze, for circular stencils in the form of a cylinder, coated with a light-sensitive lacquer.
- a lacquer stencil is obtained, the openings of which are partially closed by the hardened photoresist, but are partially permeable to the dye.
- a clamping device for a film is provided, that guides for laser optics are provided in a plane parallel to the clamping device, on which a carriage carrying the laser optics is movably arranged, and that a control unit for carriages and laser optics is provided.
- Fig.1 shows schematically the device according to the invention in oblique view.
- 2 and 3 show two views of the tension roller holder.
- the stencil tensioning roller is a circular cylinder which is expandable in the circumferential direction and runs precisely in the tensioned state and which is held on only one side for the mounting and removal of the stencils. It therefore has carrier tubes 7 at its two ends.
- a tensioning roller drive 8 is provided which interacts with a pulse generator 9.
- the tension roller drive 8 is shown as a gear drive. However, in order to avoid an error due to tolerances in the teeth, it is more favorable to provide a flat belt drive, as in FIG. 2 or 3, where a belt 19 is guided over two rollers 20, 21.
- a stepper motor for the guide carriage 6 there is a separate feed drive 10, expediently a stepper motor, the number of steps of which is to be selected in such a way that the feed carriage can be advanced step by step in each case by 10 ⁇ m.
- a stepper motor 10 is shown in FIGS. 1 and 3, this stepper motor 10 driving a screw spindle 18 which is in engagement with the guide carriage 6.
- 2 shows another embodiment for the feed drive.
- an endless belt 24 is guided over two rollers 22, 23, this belt 24 being anchored at 25 on the guide carriage 6. By driving the roller 22 or 23, the guide carriage 6 is then moved accordingly.
- the band 24 can also be replaced by a pull rope.
- a laser device 11 emits a laser beam 13 at the laser beam output 12, which is directed via two deflection stations 14 to a deflection mirror 15 on the guide carriage 6.
- An adjustment repeat 16 is provided for adjusting the position of the deflecting mirror 15 relative to the template tensioning roller.
- the deflecting mirror 15 has the task of deflecting the laser beam 13 guided parallel to the axis of the template in a direction perpendicular to the template wall.
- the pattern to be applied to the template is converted into control impulses, which can be done on the one hand by scanning a template or by storing it in an electronic system. These control pulses actuate the laser device accordingly and thus a laser beam 13 is point-wise directed onto the stencil stretched on the stencil tension roller 4.
- this laser beam removes the material covering the perforated film, so that the opening in the template is exposed again.
- the desired pattern can be transferred point by point to the template, and by jointly controlling the laser device 11 and the guide carriage 6, the pattern to be applied can also be easily repeated on the template.
- the stencil tensioning roller 4 can be designed as a circular cylinder that is expandable in the circumferential direction and runs precisely in the tensioned state. It goes without saying that care must be taken to ensure that the concentricity of the stencil tension roller has the smallest possible tolerances.
- the support tube 7 At the headstock end, ie in the drawing at the left outer end, the support tube 7 has a coupling which allows a largely rigid, but in the other direction flexible, resilient coupling of the pulse generator 9 which is free of play in the direction of rotation; the clutch is indicated at 26 in FIGS. 2 and 3.
- the right-hand end can be arranged in a bearing 2 that is provided with a pneumatic lowering device 28.
- the stencil tensioning roller 4 must be driven in the direction of rotation in such a way that only minimal synchronism fluctuations occur and other vibration excitations, such as torsional and bending vibrations, are kept extremely small and well damped.
- a drive with a friction wheel or flat belt.
- a collectorless, speed-controlled DC motor can be used as the drive.
- the focal length of the laser optics can be in a range, for example between 20 and 100 mm, and a servo slide that adjusts or adjusts the optics should subsequently be provided in order to compensate for impermissible running errors of the template tensioning roller 4.
Abstract
Cette fabrication prévoit de poinçonner de façon régulière une feuille et de la couvrir d'une couche mince, de manière que les perforations de la feuille soient fermées. En dépendance du dessin voulu, on éloigne la matière de la couche de recouvrement des perforations. Dans ce but, on étend la feuille et, dans les endroits voulus, on la soumet à un rayon laser qui libère les perforations de la couche de recouvrement.This manufacture provides for punching a sheet in a regular manner and covering it with a thin layer, so that the perforations of the sheet are closed. Depending on the desired design, the material of the covering layer is moved away from the perforations. For this purpose, the sheet is extended and, in the desired places, it is subjected to a laser beam which frees the perforations of the covering layer.
