Description
(1) technical field
The ink gun structure of the relevant a kind of ink cartridges of the utility model refers to a kind of ink gun structure and a kind of ink-jet printing system that uses this ink gun structure that dwindles the heating chip size that have especially.
(2) background technology
Along with personal computer develops gradually, ink-jet printer (ink jet printer) has become very general interface equipment, is widely used in family, personal work chamber or even all trades and professions.The major advantage of ink-jet printer is cheap, the low and good print quality of when operation noise, and printable in various medium, for example general paper, special inkjet printing paper, photo paper and special-purpose transparency etc.
Control ink gun (printhead) disengages one of key factor that ink droplet need consider for the design ink cartridges to the mechanism of ink-jet medium.Generally speaking, the mode of ink gun ejection ink droplet mainly contains two kinds of hot bubble type (thermal bubbletype) and piezoelectric types (micro piezo type).With the hot bubble type ink jet head is example, and its operating principle is to utilize heating resistor (heater resistor) heating to produce bubble and then ink is squeezed, and ink is sprayed onto on the ink-jet medium by a plurality of spray orifices.
Please see Figure 1, existing ink gun structure mainly is made up of 13 of a heating chip (heater IC) 11, one barrier layer (barrier layer) 12 and one spray nozzle sheets (nozzle plate).Heating chip 11 is that it is for having the chip of resistance heater (resistor heater), for ease of describing, hereinafter to be referred as heating chip (heater IC) for known to the general person skilled in the art person.Heating chip 11 comprises 110, the one groups of weld pads (contact pad) 111 that center on the heating resistor (not shown) of ink supply port and be positioned at the heating chip both sides of ink supply port (inkslot) that are arranged at central authorities.Form a plurality of inking chambers (ink chamber) 121 in the barrier layer 12, and 12 of the barrier layers on heating chip 11 form ink supply runner (ink channel) (not shown).A plurality of spray orifices 131 corresponding to inking chamber 121 are then arranged on the spray nozzle sheet 13.
Please see Figure 2, it is mainly as follows to make ink gun be assembled in the step of ink cartridges (ink cartridge).At first make spray nozzle sheet (nozzle plate) 13 precisions to being positioned at heating chip 11, to form an IC assembly (ICassembly); After the circuit soft board (TAB) that then makes the IC assembly and supply output to go into signal is finished and is electrically connected; At last, utilize adhesive agent with IC assembly gluing on the ink gun load bearing seat 21 of ink cartridges body 2 bottoms, finish the ink gun assembly working immediately.Please cooperate and see Fig. 1 and Fig. 2, when using this ink cartridges, the ink that is stored in ink cartridges body 2 interior ink duct (ink reservoir) (not shown)s at first flow to bottom outlet 22 from ink duct, then flow into the ink supply port 110 of heating chip 11 central authorities, enter 11 formed ink supply runners of barrier layer 12 and heating chip, flow to inking chamber 121 again, then utilize heating resistor heating to produce bubble at last and then ink is squeezed, and ink is sprayed onto on the ink-jet medium by the spray orifice on the spray nozzle sheet 13 131.
The ink gun structure of above-mentioned usefulness faces following problem:
(1) step that forms heating chip 11 central ink supply ports 110 uses sandblast processing procedure or laser beam perforation processing procedure to carry out usually, and wherein sandblast processing procedure cleanliness factor is relatively poor, and the laser beam perforation cost is high and the consideration of materials limitations arranged.
(2) process that forms heating chip 11 central ink supply ports 110 makes heating chip 11 produce cracks easily, thereby easily causes heating chip 11 fractures or circuit impaired in successive process or normal use, so that ink gun can't normal running.
(3) heating chip 11 with central ink supply port 110 has the structural strength that weakens, thereby the fracture chance improves, and causes yield to reduce.
(4) two row's heating resistors around central ink supply port 110 both sides are shared an ink supply port on the heating chip 11, therefore the phenomenon that has ink supply to have some setbacks easily takes place, and also easily produce fluid and crosstalk (cross-talk), each interactive phenomenon in ink-jet chamber influences the ink gun service behaviour unfriendly.
(5) in order to make the cause of central ink supply port 110, so heating chip 11 need have sizable size inevitably, and this has improved the cost of making heating chip greatly.
