Title (EN) METHOD FOR MANUFACTURING INK JET HEAD
(FR) PROCÉDÉ DE FABRICATION D'UNE TÊTE À JET D'ENCRE
(JA) インクジェットヘッドの製造方法
Abstract:
(EN) Provided is a method for manufacturing an ink jet head capable of more easily improving driving characteristics. A method for manufacturing an ink jet head having nozzles 111 that eject ink and piezoelectric elements 141a and a vibration plate 12 that impart, in pressure chambers 112, a pressure change to the ink inside ink flow paths communicating with the nozzles comprises: a temporary fixation step of fixing a piezoelectric plate material to a temporary fixation substrate 601 with a heat foaming adhesive 602 interposed therebetween; an element formation step of processing the piezoelectric plate material to form structures including the piezoelectric elements; a bonding step of aligning, in accordance with the pressure chambers, a reference position marker 141b serving as a reference among the structures and the vibration plate, and bonding the piezoelectric elements to the vibration plate; and a separation step of heating the heat foaming adhesive to cause the same to foam, and separating the temporary fixation substrate from the structures.
(FR) L'invention concerne un procédé de fabrication d'une tête à jet d'encre capable d'améliorer plus facilement les caractéristiques de commande. Procédé de fabrication d'une tête à jet d'encre ayant des buses 111 qui éjectent de l'encre et des éléments piézoélectriques 141a et une plaque vibrante 12 qui communiquent, dans des chambres de pression 112, un changement de pression sur l'encre à l'intérieur des trajets d'écoulement d'encre communiquant avec les buses comprenant : une étape de fixation temporaire consistant à fixer un matériau de plaque piézoélectrique à un substrat de fixation temporaire 601 avec un adhésif thermomoussant 602 interposé entre eux ; une étape de formation d'élément consistant à traiter le matériau de plaque piézoélectrique pour former des structures comprenant les éléments piézoélectriques ; une étape de liaison consistant à aligner, conformément aux chambres de pression, un marqueur de position de référence 141b servant de référence parmi les structures et la plaque de vibration, et lier les éléments piézoélectriques à la plaque de vibration ; et une étape de séparation consistant à chauffer l'adhésif thermomoussant pour amener celui-ci à mousser, et à séparer le substrat de fixation temporaire des structures.
(JA) より容易に駆動特性を向上させることのできるインクジェットヘッドの製造方法を提供する。インクを吐出するノズル111と、ノズルに連通するインク流路内のインクに圧力室112で圧力変化を付与する圧電素子141a及び振動板12と、を有するインクジェットヘッドの製造方法であって、熱発泡性粘着剤602を介して圧電板材を仮固定基板601に固定する仮固定工程、圧電板材を加工して圧電素子を含む構造物を形成する素子形成工程、構造物のうち基準となる基準位置標識141bと振動板との間で圧力室に応じた位置合わせを行い、圧電素子を振動板に接着する接着工程、熱発泡性粘着剤を加熱して発泡させ、構造物から仮固定基板を剥離させる剥離工程、を含む。
