Description
- The present invention relates to an ink jet recording head and, more particularly, to a method for manufacturing an ink jet recording head of a printer including a laminated piezoelectric element.
- As well known, an ink jet recording head of a printer including laminated piezoelectric elements utilizes a piezoelectric effect for jetting ink droplets through a plurality of ink jet nozzles from pressure chambers each forming an ink cavity.
- Fig. 1 is a flowchart showing a conventional method for manufacturing a conventional ink jet recording head, while Fig. 2 is a partial cross-sectional view of the conventional ink jet recording head at consecutive steps effected by the process of Fig. 1. A number of
cavity pattern members 5 made of a photosensitive resin as shown in Fig. 2A and each having a shape of a rectangular prism are prepared in step S10. In step S11, thecavity pattern members 5 are arranged and bonded, in a row extending horizontally as viewed in the drawing, to a surface of an elongate sheet of a piezoelectric material (first piezoelectric sheet) by thermocompression, following which a resin of the piezoelectric material is applied to the surfaces of thecavity pattern members 5 and the piezoelectric sheet to thereby form a body in which a row of thecavity pattern members 5 are enclosed by thepiezoelectric material 6a, as shown in Fig. 2B. - In step S12, a plurality of second
piezoelectric sheets 6b each having a row ofelectrode films 7 printed thereon and having a shape similar to that of the first piezoelectric sheet are layered on both surfaces of the body, as shown in Fig. 2C, and bonded thereto by compression to form a sub-assembly. In S13, a heat treatment is conducted to the sub-assembly for removing a binder and thecavity pattern members 5, the binder being contained in the piezoelectric sheets for bonding the piezoelectric sheets to corresponding one of the electrode films. Thecavity pattern members 5 are then removed to formink cavities 8 inside the sub-assembly. Subsequently, the sub-assembly is sintered to obtain the product as shown in Fig. 2D in step S14. A plurality of the resultant products are further layered one on another to form an assembly of an ink jet recording head. - With the conventional method for manufacturing an ink jet recording head of the type as described above, however, the number of steps in the process is large so that it is difficult to reduce the costs of the manufacture. Moreover, after the piezoelectric sheets and the cavity pattern members made of the photosensitive resin are bonded together by compression, a gap is often formed between the piezoelectric material and the cavity pattern members, as a result of which a problem arises that each of the resultant ink cavities does not have a dimensional accuracy.
- US-A-4 766 671 and DE-A-3 733 109 disclose methods for manufacturing ceramic electronic devices for an ink-jet head.
- In view of the foregoing, an object of the present invention is to provide a method for manufacturing an ink jet recording head which is easy to manufacture, which has a higher dimensional accuracy, and which can reduce costs.
- This object is achieved with the features of the claims.
- In accordance with the ink jet recording head of the present invention, each of the ink cavities has a dimensional accuracy and is easy to manufacture so that the costs of the ink jet recording head can be reduced.
- The above and other objects, features and advantages of the present invention will be more apparent from the following description, taken in conjunction with the annexed drawings.
- Fig. 1 is a flowchart showing a conventional process for manufacturing a conventional ink jet recording head;
- Figs 2A, 2B, 2C and 2D are cross-sectional views showing the conventional ink jet recording head at the consecutive steps of the conventional process of Fig. 1;

-
- The present invention will now be described in more detail with reference to the preferred embodiment.
- Referring to Fig. 3A, there are schematically shown
cavity pattern members 1 as used for manufacturing an ink jet recording head according to an embodiment of the present invention. Thecavity pattern members 1 are made of, for example, a photosensitive resin. Each of thecavity pattern member 1 is comprised of a pressurechamber forming portion 1a, which defines a cylindrical pressure chamber at the outer surface thereof, and cylindricalpassage forming portions 1b, which are formed at both ends of the pressurechamber forming portion 1a and have a smaller diameter to define a passage for an ink flow at the surface thereof. A number ofcavity pattern members 1 are arranged at a predetermined pitch by fixingmembers 1c with thepassage forming portions 1b fixed thereto. - Fig. 4 shows a procedure for manufacturing the ink jet recording head according to the embodiment of the present invention. First, in step S1,
cavity pattern members 1 as shown in Fig. 3A are formed from a photosensitive resin and fixed to fixingmembers 1c. Subsequently, thecavity pattern members 1 are dipped into asolution 12 including an electrode material such as platinum (Pt) contained in afirst tank 2a as shown in Fig. 3B for a predetermined period of time. The solution further includes a solvent of a binder for bonding the electrode material to thecavity pattern members 1. The resultant members are taken out from thefirst tank 2a for drying in step S3. Thus the cavity pattern member is coated by an electrode film. - Thereafter, in step S4, the resultant members are further dipped for a predetermined period of time in a
solution 13 of a piezoelectric material including a combination of, for example, PbO3, PbTiO3 and PbZrO3 contained in asecond tank 3a, and then taken out from thesecond tank 3a for subsequent drying in step S5. Thus, a piezoelectric film is formed on the electrode film. The steps S2 through S5 are repeated a plurality of times, for example three times. Thus, unitary bodies of the cavity pattern member and a laminate of the electrode films and the piezoelectric films are obtained. A group of unitary bodies are arranged in a matrix to form an assembly for the ink Jet recording head. Each of the resultant matrix of the unitary bodies does not have substantially any gap between the cavity pattern member and the laminate. - Subsequently, in step S6, a heat treatment is conducted at a temperature of about 500°C for a relatively long period of time to melt the photosensitive resin and to melt the solvent of the binder. Thus, the
cavity pattern members 1 are removed from the assembly to form an array ofink cavities 4 each including a pressure chamber and passages. At a final step S7, sintering is conducted for the resultant assembly at a temperature of 1200°C to obtain an ink jet recording head according to the present embodiment. - Fig. 5 shows a cross-section of a portion of one of they ink cavities in the ink jet recording head obtained by the process as described above. In this example, a central,
circular ink cavity 4 is surrounded by a concentric laminate of threeelectrode films 2 and three piezoelectric films 3 formed alternately with theelectrode films 2. The radius of the cavities is, for example, between 0.02 and 0.1 mm. - As described above, the laminate of the
electrode films 2 and the piezoelectric films 3 is formed around thecavity pattern members 1, substantially without any gap therebetween. As a result, after thecavity pattern members 1 are removed, each of theresultant ink cavities 4 has an accurate dimension. Also, since theelectrode films 2 and the piezoelectric films 3 are layered merely by dipping in solutions and subsequent drying, the process is quite simple, thereby reducing costs of the ink jet recording head. - In operation of the ink jet recording head as described above, a control signal for the ink jet recording head is supplied through the electrode films to operate the piezoelectric films for a piezoelectric function. The piezoelectric films 3 are concentrically formed around the
ink cavity 4, so that a uniform pressure for jetting of ink can be applied from the entire circumferential wall of theink cavity 4. This enables a smooth jetting of the ink. - The cavity pattern member may have any three-dimensional shape such as a cylinder or a rectangular prism. The three-dimensional configuration of the ink cavity allows ink to smoothly flow therein.
- In the above embodiment, the cavity pattern members are formed of a photosensitive resin. However, the material of the cavity pattern members is not limited to a photosensitive resin, but may be any of materials, such as carbon, provided that the material can be removed after formation of the laminate. If carbon is used for the material, the cavity pattern member can be removed by the sintering step (S7 in Fig.2).
