Description
SPECIFICATION
Method of manufacturing an ink jet printer comprising one or more jet nozzles.
The invention relates to a method of manufacturing an ink jet printer comprising one or more jet nozzles, the pressure chamber and the choke duct associated with each jet nozzle being recessed in a body and covered by a metal diaphragm which is common to all pressure chambers and choke ducts and on which a drive member for the ejection of an ink droplet from the associated nozzle is arranged at the area of each pressure chamber.
A printer of this kind is known from DE-OS 28 08 407. A pressure chamber which is covered by a metal diaphragm is recessed in the body. The piezoelectric drive member is arranged on top of this diaphragm. One of the electrical leads to the drive members is connected to the metal diaphragm. Consequently, this diaphragm should be comparatively thick.
Drive member, diaphragm and body are interconnected by means of a layer of adhesive. In order to achieve on the one hand a permanent connection and on the other hand a suitable electrical transition, it is necessary to realize the glued connections under a comparatively high pressure and with a comparatively long drying period. The manufacture of such an ink jet printer, consequently, is complex and time consuming.
It is also known to screw the metal diaphragm onto the body. In order to achieve a vacuumtight connection, a multitude of screws is required, notably when the ink jet printer comprises a plurality of pressure chambers. The manufacture of such an ink jet printer is again complex and time consuming.
Moreover, a vacuumtight connection between the metal diaphragm and the body is not absolutely ensured.
It has also been proposed to connect the diaphragm to the body in a vacuumtight manor by electron beam welding. According to this method, the electron beam is guided along the edges of the pressure chambers and the choke ducts so that point-like welds are formed between the body and the metal diaphragm. However, it is not possible to obtain a connection of the diaphragm exactly along the edges of the chamber.
It is the object of the invention to provide a method for connecting the diaphragm to the body of an ink jet printer so that this connection can be quickly and simply performed and that a vacuumtight and faithful connection between these two parts up to the edges of the chambers or the ducts is possible.
This object is achieved in that the body and the metal diaphragm which is arranged on the side of the body where the pressure chambers and the choke ducts are situated are clamped between two pressure plates in order to be pressed one onto the other, after which an atomic bond is established between the body and the metal diaphragm by diffusion welding. In a further version in accordance with the invention, a ceramic plate is each time arranged between the body and a pressure plate on the one side and between the metal diaphragm and the other pressure plate on the other side. This reduces the risk of fusion of the body or the metal diaphragm to the pressure plate.Tests have demonstrated that the diffusion method is particularly successful when the method is performed in vacuum and when the complete body is made of nickel and the metal diaphragm is made of steel, the diffusion temperature being approximately 900" and the assembly being maintained at this temperature for approximately from 1 5 to 20 minutes.
Diffusion methods are known per se, for example from the magazine "Metall", Volume 33, 4 (1979) pages 355 to 360. In comparison with the customary welding methods this method offers the advantage that during the welding process no phase occurs during which the materials to be treated ar liquified.
This particularly advantageous for bonding the body to the metal diaphragm of an ink jet printer, because on the one hand these parts have compratively small dimensions and because on the other hand they may not be deformed in order to maintain the chamber dimensions and the dimensions of the choke ducts. Particularly in the case of a plurality of pressure chambers, a deviation of these dimensions would have an adverse effect on the volume and the shape of the ejected ink droplets.
An embodiment in accordance with the invention will be described in detail hereinafter.
Figure 1 is a sectional view of an ink jet printer comprising six pressure chambers,
Figure 2 is a plan view of the ink jet printer shown in Fig. 1 after removal of the metal diaphragm, and
Figure 3 shows a device for diffusion welding of the body of the metal diaphragm.
The printing head of an ink jet printer as shown in the Figs. 1 and 2 essentially consists of a body 1 in which a supply duct 2 for the ink is recessed. This supply duct 2 comprises a connection piece 3. Supply ducts 6 which communicate with laterally extending choke ducts 1 2 on the surface of the body 1 open into the supply duct 2. The choke ducts 1 2 laterally open into conical pressure chambers 11. The nozzle duct 10 is arranged in the centre of these pressure chambers. These nozzle ducts 10 are passed through the base of the ink jet printer in a known manner (not shown) and, at the lower side of the base 7 they open into nozzles 1 8 which are arranged in a dense packing in a nozzle plate 9. This nozzle plate 9 is biassed against the base 7 by a tension spring 8.
The side of the body 1 in which the pressure chambers 11 and the nozzle ducts 10 are punched is covered by a metal diaphragm 4 which extends across the full width of the body 1. The drive elements 5 are arranged on this metal diaphragm 4, preferably by means of an adhesive.
The manufacture of the body and the connection to the metal diaphragm are performed so that first the conical chambers 11 and the choke ducts 1 2 are recessed in the body 1, after which the nozzle ducts 10 are drilled.
Subsequently, the metal diaphragm 4 is arranged on the body 1 and the assembly is arranged between two pressure plates 1 4 and 1 5 in order to be clamped between these pressure plates 14 and 15 by screwing. The forces required for this purpose are denoted by the reference F1 in Fig. 3. Tests have demonstrated that in order to achieve these forces F1, it suffices to apply screwing forces which do not require excessive tightening of the screws.In the case of a body comprising six pressure chambers, eight screws suffice, i.e. each time four screws on one side of the pressure plates 1 4 and 1 5. In the pressure plates 14 and 1 5 there are embedded ceramic plates 1 6 and 1 7 which are slightly larger than the body and the metal diaphragm.
The assembly thus prepared is introduced into a chamber 1 3 which is sealed so as to be airtight. The vacuum subsequently produced in this chamber 1 3 and the simultaneous heating of the assembly therein to a temperature of approximately 900"C ensure that, due to the thermal expansion, a force F2 is exerted on the metal diaphragm 4 and the body 1 which is sufficient to achieve an atomic bond between these two parts.
A particularly good bond is obtained when at least the upper side of the body 1 which faces the metal diaphragm 4 is provided with a nickel layer. However, the entire body is preferably made of nickel because it has comparactively small dimensions and also because nickel and ink, do not interact.
