Title
(EN) CLEANING DEVICE AND METHOD FOR SILK- SCREEN PRINTING OF PLATE ELEMENTS FOR ELECTRONICS OR THE LIKE
(FR) DISPOSITIF ET PROCÉDÉ DE NETTOYAGE POUR SÉRIGRAPHIE D'ÉLÉMENTS D'IMPRESSION DANS L'ÉLECTRONIQUE OU AUTRES APPLICATIONS
Abstract
(EN)
A cleaning device (10) for cleaning a silk-screen printing station able to effect a silk-screen print, by means of a print paste, of impressions on silicon or alumina- based plate elements (11), such as of the type for electronics, or other types of plate for electronics, and comprising a net (12) with incisions (13) coherent with the impressions to be printed, through which the silk-screen print of the print paste (15) is effected on the plate elements (11), comprises removal means able to be positioned below the net (12) so as to selectively remove the excess print paste (15) from the net (12). The removal means comprises at least a strip (18) provided with at least an adhesive layer (19), the strip (18) is associated with unwinding means (14, 16) so as to unwind it in a controlled manner, and with means able to take the adhesive layer (19) into contact, selectively, with at least part of the lower surface (12a) of the net (12).
(FR)
Dispositif de nettoyage (10) de poste de sérigraphie capable de réaliser une sérigraphie, au moyen d'une pâte d'impression, à partir d'impressions effectuées sur des éléments de plaques à base de silicium ou d'alumine (11), par exemple dans l'électronique, ou d'autres types de plaques en électronique; ce dispositif comprend un filet (12) avec des incisions (13) qui correspondent aux impressions à reproduire, et c'est à travers le filet en question que la sérigraphie à partir de la pâte (15) est effectuée sur les éléments de plaques (11); le dispositif comprend aussi un système d'élimination destiné à être placé sous le filet (12) pour éliminer sélectivement les excès de pâte (15) dans le filet (12); ledit système comporte au moins une bande (18) qui présente au moins une couche adhésive (19), et la bande (18) est associée à un système de déroulement (14, 16) permettant un déroulement contrôlé, et qui présente également un système capable de mettre la couche adhésive (19) en contact, de façon sélective, avec au moins une partie de la surface inférieure (12a) du filet (12).
