Abstract
The invented ink jet head of ink jet printing machine is characterized by that in the lamianted structure of ink jet head, a protective layer is added in the geometric shaped space of ink storage trough and ink flow passage, the said protective layer separates the ink from the dry membrane light barrier layer so that the dry membrane light barrier layer is not affected by the solvent of ink and dye. Said protective layer possesses sufficient film hardness and good adhesiveness.
Description
The present invention relates to a kind of ink gun of ink-jet printer, relate in particular to a kind of ink gun that is applicable to the hot bubble type ink jet printer.
The ink gun of hot bubble type ink jet printer is a bedded structure of utilizing the VLSI processing procedure to form, by ink-jet chamber inner bottom part heated chip energising back transient heating, ink droplet is sprayed the ink vaporization by spray orifice, is printed on the paper.General heated chip is bonding with spray nozzle sheet, forms 50-300 independently ink-jet chamber, and each ink-jet chamber inner bottom part uses stratie, and ink is vaporized, and causes the unexpected expansion of volume by vaporization, makes ink droplet pass the spray orifice on the spray nozzle sheet and sprays.Usually the internal geometry of the inking chamber of glued construction formation has determined the runner of ink storage capacity and ink, and the size of thick film internal geometry then is to use the gold-tinted etching technique to finish.Yet, after the manufacturing of ink ink jet-print head is finished, the internal geometry decision ink storagetank of dry film photoresistance and the runner of ink, therefore, the dry film photoresistance is inevitable in the ink-jet chamber contacts with ink, and make the dry film photoresistance be subjected to the influence of solvent and dyestuff in the ink and rotten and dissolving, and then the various defectives that cause the ink ink jet-print head produce unavoidablely, the print quality variation and the life-span of ink-jet printer are shortened.
The profile of the layer structure in the existing as shown in Figure 1 ink-jet chamber, the formation of ink gun, be in a silicon basic unit 1, to form a zone of heating 2, and then on this zone of heating 2, use the geometry that the gold-tinted etching technique forms a dry film photoresist layer 3, and its size of standard accurately, the superiors are then for having the jet orifice plate 4 of most spray orifices.In layer structure, the ink storagetank 5 of formation is to define its geometry by jet orifice plate 4, dry film photoresist layer 3 jointly with zone of heating 2 with ink runner (being the longitudinal direction of vertical ink storagetank sectional area among Fig. 1).Therefore, dry film photoresist layer 3 unavoidablely can be subjected to the influence of solvent and dyestuff in the ink 6 and rotten and dissolving, cause the change of the geometry of ink storagetank 5 and ink runner, make that ink droplet 7 is not to spray jet orifice plate 4 by way of expectations, and it is uncontrollable, and and then make the decline of print quality, the life-span of ink gun shortens even.
The ink gun of the ink-jet printer that the object of the present invention is to provide a kind of geometry of being guaranteed ink storagetank and ink runner not influenced by solvent and dyestuff in the ink and change.
The object of the present invention is achieved like this, a kind of ink gun of ink-jet printer, and it comprises: a silicon basic unit; One adds thermal insulation layer, and it is formed in the described silicon basic unit; One dry film photoresist layer, it has definite geometry that is installed in ink, is formed on described adding on the thermal insulation layer; And a jet orifice plate, it is formed on the described dry film photoresist layer; It is characterized in that it also comprises: a protective layer, it places on the surface of described dry film photoresist layer, and dry film photoresist layer and ink are isolated.
Owing to adopted above-mentioned technical solution; ink-jet storagetank that promptly forms in layer structure and ink runner divide increases by a protective layer in the geometric space; this protective layer will make that ink and dry film photoresist layer are isolated each other to be come; make the dry film photoresist layer once not be subjected to the influence of solvent and dyestuff in the ink and this protective layer to be difficult in the ink-jet chamber, producing chemical reaction and being compatible to other materials; have enough film hardness to prevent cavitation (Cavitation) and good adherence is arranged in processing procedure; increase the service life, help progressive and usability on the industry.
The present invention is further illustrated below in conjunction with embodiments of the invention and accompanying drawing.
Fig. 1 is the layer structure profile in the existing ink-jet chamber;
Fig. 2 is the profile of layer structure of the ink gun of ink-jet printer of the present invention;
Fig. 3 is the profile of the layer structure of another embodiment of the ink gun of ink-jet printer of the present invention.
Please refer to shown in Figure 2; the profile of the layer structure of the ink gun of ink-jet printer of the present invention; its formation; be in a silicon basic unit 11, to form a zone of heating 12; and then it is accurately canonical sized and form a dry film photoresist layer 13 on zone of heating 12; and on dry film photoresist layer 13, increase by a protective layer 15, and last, add jet orifice plate 14 with spray orifice in the superiors.In the manufacture process of ink gun; when the shape of dry film photoresist layer 13 via the roll extrusion of photograph slabstone mask to print, after ultraviolet ray is tanned by the sun and the gold-tinted etching technique finishes; and on dry film photoresist layer 13, increase by a protective layer 15; utilize physical vaporous deposition with metal; as Au (gold), Al (aluminium), Ti (titanium) or Ta (tantalum) etc.; add the surface that places dry film photoresist layer 13, so can allow the dry film photoresist layer avoid contacting ink 6, to block the possibility that this dry film photoresistance is rotten and dissolve.By silicon basic unit, add in the layer structure of forming of thermal insulation layer, dry film photoresist layer, protective layer and jet orifice plate, form several by jet orifice plate, protective layer and add the ink-jet chamber that thermal insulation layer defines.In addition, protective layer 15 also can add partially and places on the dry film photoresist layer 13, sees also shown in Figure 3ly, intercepts the possibility that this photoresist layer contacts with ink and can have effect of the present invention as long as reach.
In sum; the ink gun of ink-jet printer of the present invention is to add the metallic film of putting a protective effect on dry film photoresist layer surface; can the original shape of this dry film photoresistance of complete maintenance; the ink storagetank 16 that forms in the ink-jet chamber in the layer structure is defined with zone of heating 12 by jet orifice plate 14, protective layer 15 jointly with the geometry space of ink runner; break off the possibility that ink destroys the dry film photoresistance; make the good characteristic and the performance of inkjet printing quality tool of ink-jet printer; and can prolong its service life, obtain benefit economically.
