Definitions

  • This invention relates to ejecting drops.
  • Inkjet printers are one type of apparatus for depositing drops on a substrate.
  • Inkjet printers typically include an ink path from an ink supply to a nozzle path.
  • the nozzle path terminates in a nozzle opening from which ink drops are ejected.
  • Ink drop ejection is typically controlled by pressurizing ink in the ink path with an actuator, which may be, for example, a piezoelectric deflector, a thermal bubble jet generator, or an electrostatically deflected element.
  • An actuator which may be, for example, a piezoelectric deflector, a thermal bubble jet generator, or an electrostatically deflected element.
  • a typical print assembly has an array of ink paths with corresponding nozzle openings and associated actuators. Drop ejection from each nozzle opening can be independently controlled.
  • each actuator is fired to selectively eject a drop at a specific pixel location of an image as the print assembly and a printing substrate are moved relative to one another.
  • the nozzle openings typically have a diameter of 50 microns or less, e.g. around 25 microns, are separated at a pitch of 100-300 nozzles/inch, have a resolution of 100 to 3000 dpi or more, and provide drops with a volume of about 1 to 120 picoliters (pL) or less.
  • Drop ejection frequency is typically 10 kHz or more.
  • Hoisington et al. U.S. Patent No. 5,265,315 describes a print assembly that has a semiconductor body and a piezoelectric actuator.
  • the body is made of silicon, which is etched to define ink chambers. Nozzle openings are defined by a separate nozzle plate, which is attached to the silicon body.
  • the piezoelectric actuator has a layer of piezoelectric material, which changes geometry, or bends, in response to an applied voltage. The bending of the piezoelectric layer pressurizes ink in a pumping chamber located along the ink path.
  • Piezoelectric ink jet print assemblies are also described in Fishbeck et al. U.S. Patent No. 4,825,227 , Hine U.S. Patent No. 4,937,598 , Moynihan et al. U.S. Patent No. 5,659,346 and Hoisington U.S. Patent No. 5,757,391 .
  • EP 0960733 (A2 ) discloses an ink jet head having a discharging outlet face with a plurality of discharging outlets being arranged therein.
  • the peripheral area of the discharging outlets comprises a water repellent zone and a belt-like shaped, recessed hydrophilic zone which is formed in an area of the discharging outlet face which is distant by a given distance from the arrangement of the discharging outlets and which is situated next to the water repellent zone.
  • EP 1293343 (A2 ) discloses a liquid discharge recording head comprising a substrate on which an energy generating element for generating liquid discharging energy is provided, and an orifice plate which is laminated with the substrate and in which a discharge port corresponding to the energy generating element is provided.
  • WO 2004067280 discloses a fluid ejection head including an orifice layer disposed on top of a substrate layer.
  • the fluid ejection head also includes a first and a second group of fluid ejection orifices formed in the fluid ejection head, wherein the first and the second group of fluid ejection orifices are configured to eject two different fluids.
  • US 4413268 discloses jet nozzle printers in which ink droplets are ejected individually from one or more jet nozzles for a matrix print, and comprising an orifice to produce a uniform, axially proceeding ejection of ink droplets in the nozzle direction.
  • the jet nozzles are shaped such that the orifice is provided with a sharp edge, both in its interior region and also closely around this region.
  • US 6132028 discloses an orifice plate for a thermal ink jet print head with a plurality of orifice apertures and with a major surface occupying a first plane.
  • the plate has a surrounding region surrounding each of the orifices, and the surrounding region has an offset portion with an offset surface offset from the first plane.
  • the invention features a drop ejector according to claim 1.
  • the invention features a method of fluid ejection according to claim 13.
  • Embodiments may include one or more of the following advantages.
  • Printhead operation is robust and reliable since waste ink about the face of the nozzle plate is controlled to reduce interference with drop formation and ejection.
  • Drop velocity and trajectory straightness is maintained in high performance printheads in which large arrays of small nozzles must accurately eject ink to precise locations on a substrate.
  • the channels control waste ink and permit desirable jetting characteristics with a variety of jetting fluids, such as inks with varying viscosity or surface tension characteristics, and heads with varying pressure characteristics at the nozzle openings.
  • the channels are robust, do not require moving components, and can be economically implemented by machining, e.g. laser machining, or etching, e.g., in a semiconductor material such as a silicon material.
  • an inkjet apparatus 10 includes a reservoir 11 containing a supply of ink 12 and a passage 13 leading from the reservoir 11 to a pressure chamber 14.
  • the actuator is operable to force ink from the pressure chamber 14 through a passage 16 leading to a nozzle opening 17 in an nozzle plate 18, causing a drop of ink 19 to be ejected from the nozzle 17 toward a substrate 20.
  • the ink jet apparatus 10 and the substrate 20 can be moved relative to one another.
  • the substrate can be a continuous web that is moved between rolls 22 and 23.
  • the inkjet apparatus also controls the operating pressure at the ink meniscus proximate the nozzle openings when the system is not ejecting drops. Variations in meniscus pressure can cause variation in drop volume or velocity which can lead to printing errors and weeping.
  • pressure control is provided by a vacuum source 30 such as a mechanical pump that applies a vacuum to the headspace 9 over the ink 12 in the reservoir 11. The vacuum is communicated through the ink to the nozzle opening 17 to prevent ink from weeping through the nozzle opening by force of gravity.
  • a controller 32 e.g. a computer controller, monitors the vacuum over the ink in the reservoir 11 and adjusts the source 30 to maintain a desired vacuum in the reservoir.
  • a vacuum source is provided by arranging the ink reservoir below the nozzle openings to create a vacuum proximate the nozzle openings.
  • An ink level monitor (not shown) detects the level of ink, which falls as ink is consumed during a printing operation and thus increases the vacuum at the nozzles.
  • a controller monitors the ink level and refills the reservoir from a bulk container when ink falls below a desired level to maintain vacuum within a desired operation range.
  • the ink in which the reservoir is located far enough below the nozzles that the vacuum of the meniscus overcomes the capillary force in the nozzle, the ink can be pressurized to maintain a meniscus proximate the nozzle openings.
  • the vacuum is maintained at about 0.5 to about 10 inches of water.
  • nozzle plate portion 40 includes a plurality of nozzle openings 42 formed in a substantially planar substrate 41. Also formed in substrate 41 proximate each nozzle opening 42 is a cleaning structure in the form of a channel 44. Channels 44 control stray ink on the nozzle plate that could affect nozzle performance. For example, during ink jetting, ink may end up collecting on the nozzle plate. Over time, ink can form puddles which cause printing errors. For example, puddles near the edge of a nozzle opening can effect the trajectory, velocity or volume of the ejected drops. Also, a puddle could become large enough so that it drips onto printing substrate 20 causing an extraneous mark.
  • channels 44 collect, localize and direct waste ink. Referring particularly to Fig. 2A , channels 44 completely surround each nozzle opening 42 that is centered on platform area 43. Channels 44 are connected by radial channels 46 and 48 that emanate from channels 44, forming a network of connected channels that direct and hold stray fluid on the nozzle plate.
  • a nozzle opening 42 with an adjacent channel 44 is illustrated before drop ejection.
  • waste ink 38 deposits on platform area 43 and is drawn into channel 44 by capillary forces.
  • waste ink 38 is contained and distributed about nozzle opening 42 by channel 44.
  • radial channels 46 or 48 ink moves into the space defined by the radial channel and then moves under capillary action radially away from nozzle opening 42 and into the network of connected channels that direct and hold stray fluid (see Fig. 2 ).
  • waste ink moves through the network of channels under the influence of both gravity and capillary action, macroscopically in a single direction.
  • a vacuum source or wicking material can be used to remove ink from the channels.
  • the spacing, size and orientation of the channels are selected to control waste ink.
  • the spacing, S, from an edge of the channel to an edge of the nozzle opening is between about 20 % of a nozzle width, W N , or more, e.g., 30 % or more, and about five times the nozzle width or less, e.g., three times the nozzle width or less.
  • the width, W C , and depth, D, of the channel is selected to prevent excessive pooling of ink on the nozzle surface and to allow fluid to be drawn into the space defined by the channel and retained by capillary forces.
  • the channel width is between about twice the nozzle width or less and about 10 % of the nozzle width or more.
  • the channel width, W C is, e.g., about 100 microns or less, e.g., 5-20 microns
  • the channel depth, D is, e.g., about 2-10 microns or more, e.g., 50 microns.
  • the nozzle width W N is, e.g., about 200 microns or less, e.g., 25-100 microns and the spacing S from the nozzle opening to the edge of the channel is, e.g., 40 microns or greater, e.g., 100 microns.
  • the nozzle pitch is about 25 nozzles/inch or more, e.g., about 300 nozzles/inch
  • the ink drop volume is about 1 to 70 pL
  • the fluid is pressurized by a piezoelectric actuator.
  • the jetting fluid has a viscosity of about 1 to 40 centipoise and a surface tension of about 20-50 dynes/cm.
  • the jetting fluid is ink.
  • the channels can include a wicking material and/or a nonwetting coating (e.g., TEFLON ® fluoropolymer) can be applied to the nozzle plate surface between the nozzle and the channel.
  • the channel network can also be in communication with a vacuum source (not shown). Waste ink can be returned to the main ink supply or to a separate suction system.
  • the orientation of the channel is circular. In other embodiments, the orientation of the channel is sinuous.
  • the channels and/or the nozzle opening in any of the above described embodiments can be formed by machining, electroforming, laser ablation, and chemical or plasma etching.
  • the channels can also be formed by molding, e.g., injection molded plastic channels.
  • the channel, nozzle opening, and pressure chamber are formed in a common body.
  • the body can be a metal, carbon or an etchable material such as silicon material, e.g., silicon or silicon dioxide.
  • Forming printhead components using etching techniques is further described in U.S.Serial No. 10/189,947, filed July 3, 2002 , and U.S. Serial No. 60/510,459, filed October 10, 2003 .
  • the channels can be used in combination with other waste fluid control features such as apertures described in U.S. Serial Number 10/749,829, filed December 30, 2003 , wells as described in U.S. Serial Number 10/749,622, filed December 30, 2003 and/or projections as described in U.S. Serial Number 10/749,816, filed December 30, 2003 .
  • a series of projections can be included on the nozzle face proximate the channels.
  • the drop ejection system can be utilized to eject fluids other than ink.
  • the deposited droplets may be a UV or other radiation curable material or other material, for example, chemical or biological fluids, capable of being delivered as drops.
  • the apparatus described could be part of a precision dispensing system.
  • the actuator can be an electromechanical or thermal actuator.
  • the cleaning structures can be combined with a manual or automatic washing and wiping system in which a cleaning fluid is applied to the nozzle plate and wiped clean. The cleaning structures can collect cleaning fluid and debris rather than jetted waste ink.
