Ink gun manufacturing method, ink gun and printing equipment

Abstract

The invention provides an ink gun manufacturing method, an ink gun and printing equipment. The ink gun manufacturing method comprises the following steps: forming a piezoelectric element on a first surface of a base plate; forming a vibration plate on one side, opposite to the base plate, of the piezoelectric element; forming a second adhesive layer inside a space between a first plane with the upper surface of the piezoelectric element and a second surface on the vibration plate, and forming a third adhesive layer on the second adhesive layer; and exposing and developing the second adhesive layer and the third adhesive layer, curing part of photoresist on the second adhesive layer and the second adhesive layer, removing uncured parts, forming a public chamber and a pressure chamber on the second adhesive layer, and forming a plurality of ejection holes in the third adhesive layer. By adopting the ink gun manufacturing method, the ink gun and the printing equipment provided by the invention, not only are the manufacturing efficiency and the manufacturing precision improved, but also the mechanical strength and the property of a substrate are not affected even when the sizes of the pressure chamber and the side walls are reduced in machining, and the finished product rate of the ink gun is increased in the production process.

Description

technical field [0001] The invention relates to printer manufacturing technology, in particular to an inkjet head manufacturing method, inkjet head and printing equipment. Background technique [0002] In the existing technology, such as figure 1 As shown, the inkjet head structure in the printing device generally includes a substrate 100, and a plurality of pressure chambers 101 and a common chamber 103 are formed on one side of the substrate 100 through an etching process, and the plurality of pressure chambers 101 pass through the side wall 102 Separated, the common chamber 103 communicates with a plurality of pressure chambers 101 through the supply port 104, so that each pressure chamber 101 communicates with each other and supplies ink through the common chamber 103, and one side of each pressure chamber 101 is provided with On the other side of the orifice plate 200, a vibrating plate 300 and a piezoelectric element (not shown in the figure) are arranged. During prin...
