Abstract

PURPOSE:To strengthen the joint between a head body and a nozzle plate, by penetrating an adhesive through a dovetail groove formed in the nozzle plate then jointing the nozzle plate and the ink jet head body. CONSTITUTION:A gap pattern 5b thinner than a pattern 5a for a throgh-hole is patterned simultaneously with an etching pattern, then said patterns 5a, 5b are etched simultaneously to form a nozzle hole 3 and a dovetail grove 6. The dovetail groove is formed toward the center so that an adhesive spreads easily through capillary action at the circumferential section. In order to form a dovetail etching hole, the original pattern must be thin. Since a thin pattern causes abrupt droppage of etching rate, thus remaining a small hole, the liquid temperature is controlled properly. Consequently, the adhesive permeats through the dovetail groove 6 so as to joint a nozzle plate 2 and a head body 1 firmly.

ものである。A method of roughening with an etching solution is also known, but if this roughening is performed after the nozzle is completed, it will cause damage to the nozzle orifice and adversely affect the jetting condition. Furthermore, either method has the drawback of increasing the number of steps and increasing costs. Incidentally, the applicant has developed a ceramic head body 1.
A durability test was conducted by bonding a metal nozzle plate 2 with an epoxy adhesive, but peeling easily occurred between the nozzle surface and the adhesive. It was made by
This was done for the purpose of providing an inkjet head in which the head body and the nozzle plate are strongly joined.

This is characterized in that the nozzle plate and the inkjet head main body are bonded to each other by penetration of an adhesive. below,
An explanation will be given based on an example of the present invention.

The example shown in FIG. 4 is an example in which the groove width is wide at the periphery and narrows toward the center. FIG. 5 shows an example in which a spiral Φ groove 5 is formed toward the center from the periphery so that the adhesive wraps around the entire interface. In addition, in order to form etching holes in dovetail grooves, it is necessary to make the original pattern shape thinner as described above, and when the shape is made thinner, the etching rate decreases rapidly and the holes remain small.
It is necessary to appropriately control the liquid temperature, etc.
