Title:
MANUFACTURE OF INK JET HEAD
Document Type and Number:
Japanese Patent JP3105651
Kind Code:
B2
Abstract:

PURPOSE: To achieve improvement of printing quality by enabling deformation such as warpage of a head or the like to be prevented from occurring by a method wherein a resin part of the head is thickened by use of a masking plate of a recess and projection structure wherein a periphery of a masking part is made projected.
CONSTITUTION: A masking plate 4 wherein a masking part 3 by chronium vapor deposition which intercepts light for forming a nozzle in a photosensitive glass on which a recess and a projection are formed is provided at a specific position, is applied onto resin 2 by making its periphery a projected part 5. Then, the resin 2 is irradiated by ultraviolet light 6 with a mercury lamp from above the masking plate 4 to harden the resin 2 irradiated with ultraviolet light excepting the masking part 3. Then, the masking plate 4 is removed, and the resin 2 is ultrasonically cleaned with acetone to wash away the unhardened resin of the nozzle. When the resin 2 is separated from a metal mold 1, formation of the resin 2 wherein an ink passage 8 is integrally formed with the nozzle 7 is completed. Then, a glass diaphragm 10 on which a piezoelectric element 9 is cladded is bonded to the resin 2. The diaphragm 10 is coated with an ultraviolet light setting adhesive, exposed, bonded, and an ink jet head 11 will be completed.
