Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ink jet head joining apparatus, and more particularly to an ink jet head joining apparatus for joining two members constituting an ink jet head.

[0002]

2. Description of the Related Art An ink jet recording apparatus, such as a printer, a facsimile, or a copier, which records an image using an ink jet head, includes a plurality of nozzles for discharging ink droplets, and an electromechanical transducer provided for each nozzle. Using an inkjet head equipped with an actuator such as a heater or a heating resistor as a printhead, ink droplets are ejected from nozzles in response to print signals on a print medium (one to which ink drops adhere)
In this way, high-speed, high-density, and high-quality recording is performed by ejecting ink.

Various types of ink jet heads are known. For example, a plurality of piezoelectric elements are provided on a substrate, and a displacement portion of a diaphragm is joined to the piezoelectric elements.
A liquid chamber forming member for forming a liquid chamber corresponding to the displacement portion is provided on the diaphragm, and a nozzle plate (nozzle plate) having a nozzle opposed to the displacement portion of the diaphragm is formed on the liquid chamber forming member. In some cases, the piezoelectric element is driven to pressurize ink in a liquid chamber via a vibration plate, and eject ink droplets from nozzles of a nozzle plate. Also, a plurality of piezoelectric elements and columns serving as liquid chamber partition walls are alternately arranged on the substrate, and a nozzle plate having a nozzle facing the piezoelectric elements is joined to the columns, and the nozzle plate is opposed by displacement of the piezoelectric elements. In some cases, ink droplets are ejected from a nozzle that performs the operation.

[0004]

In the above-described ink-jet head, in order to perform high-density and high-quality recording, the accuracy of each of the head components must be increased, and a nozzle plate, a diaphragm, and a piezoelectric element are required. It is necessary to increase the assembling accuracy (positional accuracy between components, that is, joining accuracy) when assembling the components such as components.

In particular, during assembly, the positional accuracy between the nozzle of the nozzle plate and the displacement portion of the diaphragm, the positional accuracy between the displacement portion of the diaphragm and the piezoelectric element, and the positional accuracy between the nozzle of the nozzle plate and the piezoelectric element are increased. Otherwise, the displacement of the piezoelectric element will not be efficiently transmitted from the diaphragm to the liquid chamber, and the ink ejection efficiency will decrease, or when multiple piezoelectric elements are driven simultaneously, mutual interference will occur and the ejection speed will decrease. Inconveniences such as a decrease in image quality and a decrease in image quality occur.

Therefore, when an ink jet head joining apparatus for automatically joining two members constituting an ink jet head as described above is to be constituted, it is required to improve the alignment accuracy of the two members.
