Abstract
A printing system includes cleaning an orifice plate by inserting a tip of a shaped wiper into a slit of a printing mask, such that one or more shoulders of a handling end of the shaped wiper are in contact with respectively one or more edges of the slit. The shoulders of the shaped wiper facilitate the tip applying a predetermined pressure to an orifice surface during wiping. Preventing sediment buildup during extended periods of non-printing includes placing at least the orifice plate of the printing head in a protecting liquid that avoids evaporation of the volatile liquid from the nozzles. An innovative night plate can be used to seal the slit of a printing mask and ink purged from the printing head used to fill a gap between the printing head and the mask, thereby covering at least the orifice plate with the purged ink.

Slit) to described print media, generally, the row's nozzle on described orifice plate is only a small amount of inclined from the edge of described slit
Move.The skew of described nozzle is the most a small amount of, so described nozzle is located close to the edge of slit, in order at least two mesh
's.First purpose is shielding nozzle, rises smog from substrate, in this context, on a small quantity compared to the size of described slit, typically
Side-play amount be about 10% or less slit width, such as, slit width is 1 millimeter, side-play amount can be 100 microns or with
Under.Second purpose is during cleaning, it is simple to picks up ink under mask, in the case of easier picks up ink, few
Measure compared to the size of a diameter of flowing hole, the gap size between described mask plate and orifice plate, the characteristic of the non-wetting quality in hole,
And remove the surface tension of liquid.Such as, the diameter of flowing hole is 10 microns, and gap is 150 microns, and rational wettability and surface are opened
Power, side-play amount is 150 microns or following display is effective.
Utilize vacuum cleaning to scrape described orifice plate, use mask can reduce its efficiency further, refer to WIPO application
IB 11/051934, on May 2 2011 applying date, it advocates the priority of U. S. application case 61/330,351.
When the ink for printing is a kind of readily volatilized liquid, a part may be lost at described spray nozzle front end
Ink, remaining ink can described spray nozzle front end formed semi-solid epidermis.Described semi-solid epidermis, or solid deposition
Thing, can disturb ink to spray from nozzle, can reduce or block from the quality of one or more nozzles ejection ink.Described nozzle is difficult
To be directed at the hole on described orifice plate, also can accumulative deposit thing on described hole or orifice plate.Nozzle in literary composition, hole or orifice plate all present phase
Same sediment pile problem, owing to deposit is persistently to pile up, prints and scrapes described printhead continuously and orifice plate needs on time
Complete, or after printing for several times.During life-time service, during printing suspend or stop, sediment pile be all one special
Problem, for the long-term non-use period, the partially liq residual of ink or evaporate in nozzle, leave deposit.If wanted
Reply and print it may first have to take time and scrape described printhead to the deposit removing described nozzle.

And the difference summation of 218A and 218B (Fig. 2 A show) of described tip width.Described tip width 204 is configured sufficiently narrow,
In order to make described most advanced and sophisticated 202 to may pass through described slit, sufficiently wide, to guarantee that the whole width on discharge orifice surface is towards described mask
Can be scraped.Described tip height 206 is configured so that it is during scraping, and the described most advanced and sophisticated predetermined pressure that applies is to one
Discharge orifice surface.Discharge orifice surface described in the described location contacts of most advanced and sophisticated 202, by the angle of described holding end, the one of described most advanced and sophisticated 202
End 208 removes deposit during scraping.It is apparent from the art for those skilled in the art.Note
Meaning, Fig. 2 A-2C is side view, and described tip width 204 is the front/back direction in Y-axis, described tip height 206
It it is the up/down direction at Z axis.
Described most advanced and sophisticated 202 are positioned on described side 212, in order to configure described holding end, its have two shoulder 216A and
216B, each described shoulder described side relative to described most advanced and sophisticated 202.The shoulder width 218A of described shoulder 216A is roughly the same
Shoulder width 218B in shoulder 216B.
The shape of described holding end can change according to different application, is not limited to cube, rectangular cubic and cylinder.
Following situation be described holding end be cylinder, it has an axis and is parallel to the short transverse at described tip, described holding end
Described side is the top (or bottom) at described cylinder, and the diameter of a width of described cylinder in described side.
With reference to Fig. 2 B, being a schematic side view scraped, it has a shoulder.One print system includes that one scrapes 200,
Described most advanced and sophisticated 202 are positioned on described side 212, and in order to configure described holding end 210, it has a shoulder 216C.
With reference to Fig. 2 C, being a schematic side view scraped, it has an angled shoulder.One print system includes one
Scraping 200, shoulder 216D and 216E is not orthogonal to most advanced and sophisticated 202.According to application difference, in operation, with the material scraped
Compression, the physical characteristic of print system, applicable described angled shoulder.Specific mask and/or slit, or the system scraped
Make technique.In the case, there is a shoulder to be not orthogonal to described tip, measure described shoulder width in Y direction, be perpendicular to institute
State the Z-direction of tip height.It should be noted that somewhat subjective for measuring the described reference line of tip height, and described in scrape
Other positions wiped can also be used for measuring, according to using the concrete application scraped, and by the described concrete material spy scraping and constituting
Property.
With reference to Fig. 3, being a front-view schematic diagram scraped, the described tip length of most advanced and sophisticated 202 220 is approximately equal to described side
Wide by 214.It should be noted that Fig. 3 is a front view, make described tip length 220 X-axis left right to, and described most advanced and sophisticated high
Degree 206 is in the up/down direction of Z axis.Described tip length 220 can be arbitrary dimension, and the determination of minimum and maximum size is based on
Described slit and described in the actual size that scrapes.
Preferably, to be approximately equal to described side wide by 214 for described tip length 220.200 specifically should is scraped according to using
With, it is wide by 214 that described tip length 220 can be shorter than, be substantially equal to or be longer than described side.
With reference to the side view that Fig. 4 A is a print system, it has one and scrapes, described in scrape 200 and be inserted into described mask
Slit 106 in 104.Invisible described slit 106 in side view so that described in the tip that scrapes take the width of described slit
(such as Figure 1B, slit 106).In this case, described tip width is approximately equal to described slit width.General one or many
Individual shoulder 216 contacts at least one edge of described slit 106.Most advanced and sophisticated 202 extend through slit 106, the end 208 of most advanced and sophisticated 202
Contact the discharge orifice surface that described orifice plate 102 provides.
With reference to the front view that Fig. 4 B is a print system, it has one and scrapes, described in scrape 200 already inserted into described the narrowest
Stitch 106, and the end 208 of most advanced and sophisticated 202 contact the discharge orifice surface that described orifice plate 102 provides, it is noted that, the invisible institute of Fig. 4 B
State the shoulder scraped, described shoulder (Y-axis) direction in a front/back.Scraping on 200 described, the region of described shoulder refers to dotted line
Go out, the position of the corresponding described holding end in described tip is described.
The specific features of previous embodiment be described in the configuration that scrapes, such as, one or more shoulder contact institutes scraped
Stating mask, contact one or more edges of slit the most respectively, described tip can apply a predetermined pressure to described discharge orifice
Surface.This feature is conducive to that mask is placed one and scrapes, to prevent the shoulder of described holding end to be excessively inserting.In other words, institute
State shoulder prevent described in the tip that scrapes be pushed too far after inserted into gap, this can make described tip be applied to described discharge orifice table
The pressure in face exceedes predetermined pressure.As mentioned above, it is to avoid unnecessary pressure is intended to retain the flatness on described discharge orifice surface and non-
Wetting characteristics, and the non-infiltration coating that protection is on described discharge orifice surface, it is enough that described shoulder is also beneficial to described most advanced and sophisticated applying
Pressure is to described discharge orifice surface, and it is incorrect that applying insufficient pressure may result in scraping of uneven and described discharge orifice surface.Change
Sentence is talked about, and applying pressure is too small or is less than predetermined pressure, will be unable to by scraping the described discharge orifice surface of cleaning.
In the following description, for clarity sake, when tip applies a predetermined pressure on discharge orifice surface, and described tip applies
Pressure be odd number.Generally skilled in the art realises that the described most advanced and sophisticated pressure applied, can scrape from one and scrape to another, often
One scrapes change in the range of an acceptable predetermined pressure.Preferably minimum pressure is to remove deposition from discharge orifice surface
Thing.Preferably maximum pressure is less than most advanced and sophisticated at the hurtful pressure in described discharge orifice surface.Described discharge orifice is being contacted with tip
The static pressure applied during surface, different with the pressure during scraping (may contact described point during described discharge orifice surface
The dynamic mobile of end).Between described most advanced and sophisticated and described discharge orifice surface, any different static state and dynamic pressure contact, Ying
In the range of predetermined pressure, to remove deposit and anti-checking hole damaged surfaces.The innovation of shape and the use of shaping tube scraper,
There is provided described tip in the range of a predetermined pressure, described discharge orifice surface is applied pressure.
General slit width 112 is 1 millimeter, it is also possible to for higher value, such as 2 millimeters.It should be noted that slit aperture is relatively
There is greatly less shield effectiveness.Slit width can also be smaller value, such as 0.3 millimeter or even 0.1 millimeter.At described slit
Glacing flatness in, described minima equal on nozzle diameter increase uncertainty, and in slit nozzle array alignment ability,
By slit aperture without interference with injection.The minima of one physical constraints of slit pore, is to need frequently to scrape described in (scraping)
Orifice plate.Described tip width 204 preferred embodiment is equal to slit width.Due to the acceptable specification of world's product needed,
The specification that tip width is possible is the slit width that slit width adds 10%: tip width=slit width+(0～10%).This
Description is at the fact that reaction to wipe curette be resilient in described molding, and the tip that curette is wiped in described molding may be inserted into
The slit that the most advanced and sophisticated width of curette is narrower is wiped than molding.Description also react a kind of may, it is ensured that scrape after orifice plate is whole
Slit width.In a unrestriced example, the tip width of 1.1 millimeters is used to scrape the slit of 1.0 millimeters.
In the ordinary course of things, described nozzle (discharge orifice) from the distance of the edge offset amount of described slit be 120 microns positive and negative
30 microns.Owing to relatively small nozzle is from the edge offset of this slit, to guarantee that the whole discharge orifice surface above slit is scraped
It is important for wiping, and therefore tip width and tip height is important, successfully realizes described molding and wipes the function of curette.
In a case where, described discharge orifice surface has one or more hole, and it has bore dia (also referred to as discharge orifice width
Degree) in the context of presents, preferred tip width 204 at least etc. is wider than described bore dia, so that described molding
The tip wiping curette is scraped by described hole.
Shielding depth 118, distance between 104 bottom the surface of described orifice plate 102 and mask, usually 0.4 millimeter adds
Going up or deduct 0.6 millimeter (shielding depth=0.4+-0.6 millimeter), described tip height 206 preferably shielding depth adds or subtracts
Remove first height (tip height=shielding depth+-20% to 30% the first height) of 20% to 30%.
Preferably, the tip shaping tube scraper is open-cell material, such as open celled foam.Open-cell material absorbs liquid, promotes
Most advanced and sophisticated absorption cleaning solution before scraping.During scraping, cleaning solution utilizes open celled foam to can get discharge orifice on discharge orifice surface
Surface loosens and/or the deposit of binding, and during scraping, open celled foam promotes that ink is entered by capillarity and deposit
Enter the open celled foam at described tip, thus remove the deposit on discharge orifice surface.
As it has been described above, described orifice plate scribbles non-infiltration coating often.Described non-infiltration coating easily scrapes because of improper
And scratch.Therefore, the tip shaping tube scraper should be sufficiently flexible, to prevent non-infiltration coating scratch, eliminates and damages with other.
The functional packet being preferred for shaping the most advanced and sophisticated open-cell foam materials of tube scraper contains as follows, but is not limited to this:
Do not damage the soft non-infiltration coating (chemically and physically) of orifice plate,
Relative to positive inertia dispersant,
The temperature (40 ÷ 60 DEG C) that head can bear,
Keep elasticity,
