Title (EN) SOLDER FLUX APPLICATOR
(FR) APPLICATEUR DE FLUX DE SOUDURE
Abstract:
(EN) An apparatus (10) for spraying a liquid, such as a low-solids flux, onto a substrate (12), during its transit along a first path (15), comprises a spray gun (38) directed at the substrate. The gun (38) is carried by a carriage (34) reciprocated by a traversing mechanism (42, 44, 46) which reciprocates the gun back and forth along a second path (30) generally perpendicular to the first path (15). The spray gun (38) is reciprocated such that its spray pattern during each pass slightly overlaps the pattern made during the previous pass, thereby achieving substantially uniform liquid coating on the substrate. Each time the gun (38) reaches an end of its travel, its tip (39) is advantageously cleaned automatically by a brush (84) wetted by a solvent to avoid tip clogging.
(FR) Appareil (10) servant à pulvériser un liquide, comme un flux à faible teneur en matières solides, sur un substrat (12), lors de son passage le long d'un premier parcours (15), et comprenant un pistolet pulvérisateur (38) dirigé vers le substrat. Le pistolet (38) est porté par un chariot (34) dont le mouvement de va-et-vient est commandé par un mécanisme de déplacement (42, 44, 46) qui rapproche et qui éloigne le pistolet sur toute la longueur d'un deuxième parcours (30) en général perpendiculaire au premier parcours (15). Le pistolet pulvérisateur (38) effectue un mouvement de va-et-vient tel que la marque de la pulvérisation laissée lors de chaque passage, recouvre la marque réalisée lors du passage précédent, ce qui permet d'obtenir, à la fin, une couche de liquide pratiquement uniforme sur le substrat. Chaque fois que le pistolet (38) atteint la fin de son parcours, le bout (39) de celui-ci est automatiquement nettoyé par une brosse (84) mouillée de solvant, ce qui évite l'obstruction dudit pistolet.
