Abstract

PURPOSE:To joint a nozzle plate to the main body of a head so as to prevent deformation or breakage of the plate or leakage of an ink between the plate and the main body, by jointing the nozzle plate to the main body of the head through a shock-absorbing member by a press plate. CONSTITUTION:A shock-absorbing member 5 is inserted into the groove 3 of the main body 1 of a head, and a nozzle plate 6 is provided so that it contacts a front face of the main body 1 while making close contact with the shock- absorbing member 5. The nozzle plate 6 is pressed by the press plate 8, and is fixed to the main body 1 by screws passed through clearance holes 10. Accordingly, the nozzle plate can be fitted to the main body of the head in a purely mechanical manner, the nozzle plate and the press plate make surface contact with each other to uniformly dispese a force exerted on the plate, and the plate is hardly broken.

ートが破損するという欠点があった。Currently, monocrystalline materials such as silicon that are anisotropically etched are used as multi-nozzle plates for inkjet printing. However, it has been difficult to attach this nozzle plate made of silicon single crystal material to the head member. For example, attempts have been made to heat and diffuse bond the head member and the nozzle plate made of silicon single crystal plate.
There was a drawback that when the head member was returned to room temperature, the nozzle plate was damaged due to the difference in coefficient of thermal expansion between the head member and the nozzle plate made of a silicon single crystal plate.

In addition, the material of this buffer member 5 is as follows from the viewpoint of wettability with ink:
Fluororubber is preferable. Furthermore, the nozzle plate 6 is a single-crystal silicon wafer processed by anisotropic etching, etc., but in order to increase the contact area with the holding plate 8, a larger silicon wafer with holes formed is used. desirable. Further, the holding plate 8 is a nozzle plate 6
Except for the nozzle hole part, the contact surface is finished with high precision so that surface contact can be made with the nozzle plate 6, and the flatness of the contact surface is 01 or less, and is finished to a mirror surface by polishing or puff polishing. ing. Further, when the cushioning material 5 has a circular cross-sectional shape as shown in FIG. 2, the crushing margin of the cushioning material 5 is preferably 15 to 35 inches of the cross-sectional diameter.

ら液漏れがないという利点がある。Since the nozzle plate 6 is bonded to the head body 1 in this way, there is no need to use an adhesive that does not give good results to the ink, and unlike diffusion bonding, which causes nozzle damage due to differences in thermal expansion. Even if the nozzle plate is not very strong mechanically, such as a nozzle plate made of a single crystal silicon wafer, it can be easily attached to the head body purely mechanically. In addition, since the nozzle plate 6 and the holding plate 8 are in surface contact, the force applied to the nozzle plate is evenly distributed during installation, and even if the mechanical strength is not very strong, the nozzle plate 6 will not be damaged and can be easily installed. As explained above, according to the present invention, the nozzle plate is attached to the head body via a cushioning material and is held down by a holding plate.
Further, since the surfaces of the nozzle plate and the presser plate are brought into contact with each other, there is an advantage that the nozzle plate is not deformed or damaged, and there is no leakage of liquid from between the nozzle plate and the head body.
