Title
(EN) VACUUM WIPER AND STENCIL PRINTER WITH VACUUM WIPER
(FR) ESSUYEUR À VIDE ET IMPRIMANTE AU POCHOIR AVEC ESSUYEUR À VIDE
Abstract
(EN)
A vacuum wiper, comprising a housing, a connection port, multiple holes and a hole adjusting means; the housing contains a cavity; the connection port is disposed on the housing and is in communication with the cavity; the multiple holes are disposed on the housing in the length direction of the housing, such that the cavity of the vacuum wiper housing is able to be in fluid communication with the outside via the multiple holes. The vacuum wiper has a maximum vacuumizing length when all of the multiple holes are in communication with the outside. The hole adjusting means is configured to be capable of blocking one or more of the multiple holes in sequence from two ends in the length direction of arrangement of the multiple holes of the vacuum wiper, such that the vacuum wiper is able to adjust the vacuumizing length. The provision of the hole adjusting means enables the vacuum wiping apparatus to have an adjustable vacuumizing length, in order to match the wiping of stencils with different length specifications, thereby effectively increasing the vacuumizing efficiency of the vacuum wiping apparatus and reducing the production cost.

La présente invention concerne un essuyeur à vide, comprenant un boîtier, un orifice de connexion, de multiples trous et un moyen de réglage de trou ; le boîtier contient une cavité ; l'orifice de connexion est disposé sur le boîtier et est en communication avec la cavité ; les multiples trous sont disposés sur le boîtier dans le sens de la longueur du boîtier, de telle sorte que la cavité du boîtier d'essuyeur à vide peut être en communication fluidique avec l'extérieur par l'intermédiaire des multiples trous. L'essuyeur à vide a une longueur de mise sous vide maximale lorsque tous les multiples trous sont en communication avec l'extérieur. Le moyen de réglage de trou est conçu pour être apte à bloquer un ou plusieurs des multiples trous en séquence à partir de deux extrémités dans le sens de la longueur d'agencement des multiples trous de l'essuyeur à vide, de telle sorte que l'essuyeur à vide est apte à régler la longueur de mise sous vide. La fourniture du moyen de réglage de trou permet à l'appareil d'essuyage à vide d'avoir une longueur de mise sous vide réglable, afin de correspondre à l'essuyage de pochoirs avec différentes spécifications de longueur, ce qui permet d'augmenter efficacement l'efficacité de mise sous vide de l'appareil d'essuyage à vide et de réduire le coût de production.
