Title
(EN) A STENCIL PRINTING MACHINE
(FR) MACHINE D'IMPRESSION PAR STENCIL
Abstract
(EN)
The present application relates to a stencil printing machine, which comprises a first holder device (110), a mobile device (121), two support tables (131, 132) and two driving devices (151, 152), wherein the first holder device (110) is configured to be able to horizontally reciprocate in the portrait orientation, the mobile device (121) is mounted on the first holder device (110) and is configured to be able to horizontally reciprocate in the landscape orientation on the first holder device (110), the two support tables (131, 132) are mounted at the lower end of the mobile device (121) and are used to bear corresponding solder paste jars (141, 142), the two driving devices (151, 152) are mounted on the mobile device (121) so that each of the two driving devices (151, 152) is located above a corresponding support table (131, 132) and is used to press a corresponding solder paste jar (141, 142), and the mobile device (121) is configured to be able to drive the two support tables (131, 132) and the two driving devices (151, 152) to reciprocate vertically. Two standard solder paste jars (141, 142) can be assembled for the stencil printing machine provided by the present application. When one solder paste jar (141, 142) is empty, solder paste supply is switched to the other solder paste jar (141, 142) and the stencil printing machine can continue to operate without stopping, thus improving the working efficiency of the stencil printing machine significantly.

La présente invention se rapporte à une machine d'impression par stencil, qui comprend un premier dispositif de support (110), un dispositif mobile (121), deux tables de support (131, 132) et deux dispositifs d'entraînement (151, 152), le premier dispositif de support (110) étant configuré pour pouvoir effectuer un mouvement de va-et-vient horizontal dans l'orientation de portrait, le dispositif mobile (121) étant monté sur le premier dispositif de support (110) et étant configuré pour pouvoir effectuer un mouvement de va-et-vient horizontal dans l'orientation de paysage sur le premier dispositif de support (110), les deux tables de support (131, 132) étant montées au niveau de l'extrémité inférieure du dispositif mobile (121) et étant utilisées pour porter des pots de pâte à souder correspondants (141, 142), les deux dispositifs d'entraînement (151, 152) étant montés sur le dispositif mobile (121) de telle sorte que chacun des deux dispositifs d'entraînement (151, 152) soit situé au-dessus d'une table de support correspondante (131, 132) et soit utilisé pour presser un pot de pâte à souder correspondant (141, 142), et le dispositif mobile (121) étant configuré pour pouvoir entraîner les deux tables de support (131, 132) et les deux dispositifs d'entraînement (151, 152) pour effectuer un mouvement de va-et-vient verticalement. Deux pots de pâte à souder standards (141, 142) peuvent être assemblés pour la machine d'impression par stencil fournie par la présente invention. Lorsqu'un pot de pâte à souder (141, 142) est vide, une alimentation en pâte à souder est commutée vers l'autre pot de pâte à souder (141, 142) et la machine d'impression par stencil peut continuer à fonctionner sans arrêt, ce qui permet d'améliorer de manière significative l'efficacité de travail de la machine d'impression par stencil.
