Description
Technical field
The present invention relates to a kind of automatic testing method of ink-jet printer, relate in particular to a kind of automatic testing method of color inkjet printer negative pressure system.
Background technology
With the progressively development of ink-jet technology, inkjet technology is widely used in all trades and professions, like advertising, packing business, press etc.Ink supplying mechanism of ink-jet printer of the prior art mainly divides two big types, the ink supply of a kind of employing siphon principle, the ink supply of another kind of employing negative pressure system.As shown in Figure 1, adopt the ink feeding system of siphon principle to the shower nozzle ink supply, liquid level is lower than shower nozzle 2 in the assistant print cartridges 1, and like h, assistant print cartridges 1 moves with shower nozzle 2.Assistant print cartridges 1 is installed too high, and ink flow rate is too fast, and shower nozzle 2 is prone to the China ink that overflows; Assistant print cartridges 1 is installed too low, and ink flow rate is too slow, and print procedure is prone to shower nozzle 2 disconnected black phenomenons.This ink feeding system is simple in structure, but because it must be lower than the shower nozzle workbench, can not print the flat-type material, and assistant print cartridges is oversize from pipe-line, causes the nozzle surface negative pressure unstable easily.
As shown in Figure 2, adopt the ink feeding system of negative pressure to the shower nozzle ink supply, assistant print cartridges 3 setting height(from bottom)s are usually above shower nozzle 4, and like H, ink flows into shower nozzle 4 from assistant print cartridges 3 through the ink supply pipe under the effect of gravity.Through the gravity that negative pressure system provides negative pressure to overcome ink, can realize assistant print cartridges according to the printing demand continue, stable, in right amount to the shower nozzle ink supply.
As shown in Figure 3; The negative pressure system pipeline of prior art is very complicated; Print negative pressure system for six looks and mainly comprise six assistant print cartridges 21～26, nine magnetic valves 31～33,211～261, B/P EGR Back Pressure Transducer EGR 11, negative pressure cavity 7, negative pressure pump 6, positive pressure pump 5, Pressure gauge 10, gas circuit pipe, vent valve 8,9 and control circuits etc.Keep the stable of negative pressure in the pipeline according to the negative pressure value control circuit of B/P EGR Back Pressure Transducer EGR 11 feedback through the work of control magnetic valve 31,32 and negative pressure pump 6.In the ink jet printing process; With dolly shake back and forth cause that each pipe joint gets loose, the negative pressure system pipeline is aging, the factors such as the gas leakage of gas circuit pipe joint, negative pressure pump cisco unity malfunction and purge valve malfunction of negative pressure system all will make negative pressure unstable; Ink overflows from shower nozzle; Cause shower nozzle can't carry out normal printing; The frequent break-make electricity of magnetic valve and vavuum pump, shorten service life.Six looks are printed negative pressure system and are had 50 joints, 25 sections pipelines.In case gas leakage, its possible part that goes wrong is a lot, and prior art adopts one place, manual place investigation, because the invisibility of blowby gas path has more increased its detection difficulty.For printing the more ink-jet printers of chromatic number, the pipe joint quantity of its negative pressure system is many more, gas circuit Guan Yuechang, and detection difficulty is bigger.

The specific embodiment
Before operation negative pressure self checking method of the present invention, on negative pressure system, record following parameter value through experiment: 1) close magnetic valve, negative pressure system reaches the time T 1 of bleeding that negative pressure value P1 needs; 2) open vent valve, the record negative pressure is reduced to the time T 2 of P2 by P1; 3) the operating frequency f of pump; 4) air pump inoperative duration t.The above-mentioned P1 of different negative pressure systems, P2, T1, T2, f and t value are different.
The automatic testing method of ink-jet printer negative pressure system of the present invention may further comprise the steps: the user selects the detection scheme of negative pressure system according to actual needs through inputting interface; The P1, T1, P2, T2, f and the t that record according to experiment adjust the normative reference value in the detection scheme through inputting interface; The trace routine of this detection of negative pressure scheme of processor operation, and output testing result.
Above-mentioned detection of negative pressure scheme comprises that full detection and single gas circuit pipe detect, and full the detection is under the condition of negative pressure cavity operate as normal, is used to detect whether operate as normal of whole negative pressure system.It is to be used to detect whether operate as normal of main gas circuit pipe and each secondary gas circuit pipe branch road that single gas circuit pipe detects.Describe two kinds of detecting patterns of the negative pressure system detection method of ink-jet printer of the present invention in detail below in conjunction with Fig. 3, Fig. 4:
One, full detecting pattern
The precondition of full detecting pattern is the negative pressure cavity operate as normal of negative pressure system.Comprise the detection whether secondary gas circuit pipe branch roads such as negative pressure pump, vent valve, main gas circuit pipe and C, M, Y, K leak gas under this pattern.Before each gas circuit pipe branch road of test, need to guarantee that negative pressure pump and vent valve are operate as normal, could detect main gas circuit pipe branch road then, be only at last and detect each secondary gas circuit pipe branch road.
Detect earlier whether operate as normal of negative pressure pump, negative pressure pump is bled earlier the T1 time, the negative pressure value in the negative pressure cavity and preset reference standard value P1 are made comparisons, if negative pressure value is near P1 in the negative pressure cavity, and demonstration negative pressure pump OK on LCD then; If not, then withdraw from and detect and output error signal on LCD.
Next detect whether operate as normal of vent valve; Wait for that T2 after the time, measures negative pressure value in the negative pressure cavity, if be reduced to the normal level P2 of setting, then vent valve is normal; If not, then withdraw from and detect and output vent valve mistake on LCD.
Next detect each gas circuit pipe;
Two, single gas circuit pipe detecting pattern
Under the situation of negative pressure pump and vent valve operate as normal, this pattern is used for detecting main gas circuit pipe and whether secondary branch road gas circuit pipe leaks gas.
Close all magnetic valves, open negative pressure pump, contrast negative pressure pump frequency whether greater than the normative reference value f that presets or maximum pump work time whether greater than the normative reference value T that presets, be, then withdraw from detecting pattern or on LCD the main gas circuit pipe of output make mistakes; Not, whether be then to illustrate main gas circuit plumber do normally greater than the normative reference value t that sets the lasting down time that then contrasts negative pressure pump.Next detect secondary branch road gas circuit pipe, opening needs the secondary gas circuit pipe i that detects to go up and secondary black tank connected magnetic valve.Whether contrast negative pressure pump frequency is that then the secondary branch road gas circuit pipe of output is made mistakes on LCD greater than the normative reference value f that presets; , then do not contrast negative pressure pump not run duration be to illustrate that then the secondary branch road gas circuit of i plumber does normally, output i passage OK or well on LCD whether greater than the normative reference value t that sets.Next i+1 continues other secondary branch road gas circuit pipe of inspection, till all secondary branch road gas circuit pipe inspections finish.
The automatic testing method of the ink-jet printer negative pressure system that the present invention proposes; Automatically detect and display routine through in existing inkjet printing machine circuit, increasing negative pressure; Realize the automatic detection of negative pressure system; Simplify the detection of negative pressure process; Find out the trouble point of negative pressure system in the time of prediction negative pressure system health status fast and easily, guarantee the stability of ink-jet printer negative pressure system.
