Background technology

Progress along with numeral science and technology, print-out device has become general common computer peripheral device, and the ink-jet printer in the print-out device is not only cheap, processing ease, and it is printable in multiple ink-jet medium, as paper, photo paper etc., so risen to main flow machine into print-out device.

Generally speaking, the print quality of ink-jet printer depends on the design of ink cartridges, and wherein the ink gun of ink cartridges disengages the structural design of ink droplet to the ink-jet medium, the especially number of spray orifice and arrangement mode thereof, the significant consideration that designs for ink cartridges.

Take a broad view of the structure of thermal vapor bubble type (thermal bubble) ink gun ejection ink droplet, for higher definition demand, manufacturer there's no one who doesn't or isn't develops the method that increases the spray orifice number of permutations with great concentration in the design of ink gun.See also Fig. 1 (a), it is the structural representation of existing ink cartridges, as shown in the figure, existing ink cartridges mainly comprises ink gun 1 and ink cartridges body 3, and ink gun 1 is to use the structure of side ink supply runner and print chip 11 and 12 of jet orifice plate (nozzle plate) are formed by one.The surface of printing chip 11 has heating resistor (resistor heater) 110, the both sides of printing chip 11 then for go out black side 111 can and ink cartridges body 3 between constitute side ink supply runner (ink channel) 112, printing chip 11 also comprises a barrier layer (barrierlayer) 113, be arranged on the surface of printing chip 11, and and going out of printing chip 11 define a plurality of inking chambers 114 between the black side 111, then is provided with heating resistor 110 in each inking chamber 114.In addition, jet orifice plate 12 has a plurality of spray orifices 121 corresponding to inking chamber 114, when jet orifice plate 12 and printing chip 11 are combined into ink gun 1, when being assembled on the load bearing seat 31 of ink cartridges body 3 again, can be overlapping because of jet orifice plate 12 with flexible circuit board 21, easily make ink from the slit 13 ink leaks.

Because, ink-jet printer mainly is by ink gun 1 ink to be sprayed onto on the ink-jet medium, therefore the project organization of ink gun 1 with and to be comprised packaged type between the assembly be the key factor of print quality and cost of manufacture of concerning, see also Fig. 1 (b), it is the encapsulation schematic diagram of existing ink gun, the method for packing of existing ink gun is to use the automatic joining technique of winding (tape automated bonding, TAB), at first, in a winding 2, make circuit to form flexible circuit board 21, and an opening 22 is set in the precalculated position of flexible circuit board 21, then jet orifice plate 12 is placed in the opening 22 and location and secure bond on flexible circuit board 21, then make the heating resistor 110 on the printing chip 11 be in corresponding position in the mode of accurate contraposition printing chip 11 again with spray orifice 121 on the jet orifice plate 12, and need simultaneously printing chip 11 is incorporated on jet orifice plate 12 and the flexible circuit board 21, again winding 2 is cut into suitable length, to form a flexible circuit board component, at last, the flexible circuit board component of finishing purchasing is pasted on the load bearing seat 31 of ink cartridges body 3 with sticker, just can finish the ink gun encapsulation work shown in Fig. 1 (c).So printing chip 11 just can receive the triggering of the control signal that the system, control circuit (not shown) of ink-jet printer transmitted by flexible circuit board 21, and ink cartridges body 3 inner stored inks are heated, and be injected on the ink-jet medium (not shown) by the spray orifice on the jet orifice plate 12 121.

Yet ink gun 1 structure of the use side ink supply runner 112 shown in Fig. 1 (a), because the configuration of inking chamber 114 is tied to side ink supply runner 112, therefore ink gun 1 can only be provided with inking chamber 114 on the surface of printing chip 11 close dual-side ink supply runners 112, and this will make spray orifice 121 numbers of permutations of ink gun 1 be restricted and make definition to improve again.
