Definitions

  • the present invention relates to ink-jet printers, and, more particularly, to alignment of the printhead and carriage and an electrical interconnect lock-in mechanism for controlling the printhead.
  • a printhead In ink-jet printing technology, a printhead, com­prising a plurality of nozzles in a nozzle plate, is fluidically associated with a reservoir of ink.
  • the printhead is mounted on one end of a print cartridge and the reservoir is provided inside the cartridge.
  • An interconnect means which carries electrical signals from a microprocessor in the printer to the printhead.
  • these signals provide a current to resistors associated with the nozzles and thus control the heating of specific resistors, which in turn form droplets of ink.
  • the droplets of ink are expelled through the nozzles toward a print medium, such as paper.
  • the particular pattern of resistor heating controls the pattern of characters formed on the print medium.
  • the print cartridge is supported in a carriage, which is adapted to move bidirectionally, normal to the movement of the print medium through the printer.
  • the carriage movement is controlled by a motor and an asso­ciated belt drive, with the motor controlled by the microprocessor.
  • a printhead cartridge and carriage assembly comprising:
  • the cartridge has top, bottom, sides, front and rear surfaces and includes a printhead on the bottom surface, a contact on the back surface connected to the printhead, referencing pads on the side surfaces, and a lip on the back surface for accepting a snap spring for locking the cartridge in position in the carriage.
  • the securing means includes the snap spring and means for receiving the referencing pads on the cartridge.
  • the force loading means urge the interconnect means against the contact of the cartridge.
  • the printhead cartridge/carriage assembly of the invention requries only one hand of the operator to both insert and lock the cartridge in position.
  • the cartridge/carriage assembly provides simul­taneous alignment of the nozzle plate in the X, Y, and Z directions
  • contact between the printhead and the interconnect means is reliably made each time the cartridge is inserted and locked in position, thereby ensuring proper nozzle firing each time.
  • FIG. 1 a print cartridge/carriage assembly, denoted generally at 10, is shown in FIG. 1.
  • the assembly 10 comprises a carriage 12 in which a print cartridge 14 is depicted, locked into position.
  • An interconnect strip 16 pro­vides electrical signals from a microprocessor (not shown) to the cartridge 14, as discussed more fully below.
  • the carriage 12 comprises a base support 18 and a chute 20 affixed thereto by fas­tening means 22.
  • the carriage 12 advantageously com­prises a glass-filled, carbon-filled, polytetrafluoro­ethylene-filled, silicon-filled polycarbonate.
  • the interconnect strip 16 and a spring pad 24 are sandwiched by the support 18 and chute 20.
  • the spring pad 24 comprises a resilient, elastomeric material and, as seen in FIG. 3, comprises a plurality of resilient bumps 26.
  • the spring pad 24 is seated in a depression 25 (shown in FIG. 4) in the carriage base support 18, behind a portion of the interconnect strip 16, as de­scribed more fully below.
  • the base support 18 and chute 20 are aligned in proper relationship by molded-in features such as pipe 27, which engage through corresponding openings in the interconnect strip 16 into opposed openings in the other member.
  • the interconnect strip 16 comprises a strip of flexible dielectric material, carrying a plurality of electrically conducting lines 28, as seen more clearly in FIG. 8.
  • the conducting lines 28 terminate in convex contact bumps or dimples 30, which are configured in a particular pattern.
  • the bumps 26 on the spring pad 24 are configured in the same pattern as the contact dimples 30 on the interconnect strip 16. As seen in FIG. 7, the spring pad pumps 26 provide a force loading means against the contact dimples 30 to urge them against the cartridge 14.
  • the cartridge 14 comprises top 32, bottom34, sides 36, 38, front 40 and back 42 surfaces.
  • the car­tridge 14 advantageously comprises a modified poly­phenylene oxide.
  • a printhead 44 is provided on the bottom surface 34.
  • the printhead 44 comprises a plurality of resis­tors (not shown) associated with a plurality of nozzles (not shown) formed in a nozzle plate (not shown).
  • Ink (not shown) is stored in a reservoir interior the car­tridge 14.
  • the cartridge 14 also includes a contact strip 46 on the back surface 42, which wraps around to the bot­tom surface 34 to provide a plurality of conducting paths or traces to the resistors.
  • each resistor is supplied by an electrical signal along a unique conducting path.
  • the contact strip 46 includes a plurality of concave contact pads 48, which are ar­ranged in the same pattern as the convex contact dim­ples 30 on the interconnect strip 16. Locking of the cartridge 14 in the carriage 12, as described in great­er detail below, matches up the contact dimples 30 with the contact pads 48, to provide an electrical path from the microprocessor to each of the resistors in the printhead 44.
  • the contact strip 46 comprises a flexible material having a plurality of electrical traces thereon.
  • a tape automated bond (TAB) circuit of the type manufactured and sold by 3M Company (Minneapolis, MN) is employed.
  • the top surface 32 of the cartridge 14 is provided with a pair of finger grips 50a, 50b.
  • the larger fin­ger grip 50a terminates in a V-shaped member 52a, which may be provided with an arrowhead insignia to denote the proper direction of orientation of the cartridge 14.
  • Lock-out ears 54 further act to prevent mis-orientation of the cartridge 14 in the carriage 12.
  • Reference pads 56 are provided on the cartridge 14 near the base thereof.
  • two sets of reference pads 56 are pro­vided; these comprise sculpted surfaces that align the nozzle plate in the X, Y and Z directions.
  • the X ref­erence pad 56x is a surface parallel to the side sur­face 38. (There is only one X reference pad 56x, since the carriage 12 is provided with a side spring 58 which urges against the opposite side surface 36 to force the cartridge against one side of the chute 20.
  • the Y reference pad comprises the upper vertical surface 56y of the sculpted surface.
  • the Z reference pad comprises the inner horizontal surface 56z of the sculpted sur­face.
  • the junction of 56y and 56z comprises a pivot or rotation point 56r, about which the cartridge 14 ro­tates during the lock-in operation.
  • Downwardly depending L-shaped members 60a,b on the support base 18 each cooperatively engage one of the reference pads 56 in mating association.
  • the L-shaped members 60a,b provide reference sur severelyface against which the reference pads 56 of the car­tridge bear.
  • reference pad 56x bears against reference surface 60x on member 60a (the member on the opposite side of the side spring 58).
  • Reference pads 56y push back against reference surfaces 60y (shown in FIG. 2).
  • Reference pads 56z bear down on reference surfaces 60z.
  • the snap-spring 62 is housed in a molded-in fea­ture 66 of the carriage support base 18.
  • a mating housing 67 which sits above the snap-spring 62 when the base 18 and chute 20 are assembled, includes an inward V-shaped surface 67a, which receives the simi­larly-shaped surface 52a of the cartridge 14.
  • the rear of the housing 66 comprises a finger grip 68.
  • the front of the cartridge chute 20 is also provided with a finger grip 20b.
  • the support 18 of the carriage 12 includes a bear­ing 70, which is associated with a carriage rod (not shown).
  • the carriage rod is positioned substantially parallel with the paper drive axis (not shown), and permits bidirectional movement of the carriage 12 therealong.
  • the carriage 12 is moved by a belt (not shown), attached to the carriage by a belt attachment 72.
  • the belt is attached to a carriage drive motor (not shown), which is controlled by the microprocessor.
  • a reference means, or slider bump, 74 rides on the surface of a carriage guide 76.
  • the weight of the carriage 12 preloads the slider bump 74 against the carriage guide 76, thereby making constant contact.
  • the slider bump 74 comprises a low-friction, long wear­ing material and may be a separate piece or a molded-in feature of the carriage 12.
  • the slider bump 74 serves to maintain the printhead 44 a constant, fixed distance from the print medium.
  • the carriage base 18 also includes an interposer arm 78 secured in a tube 80.
  • the function of the interposer arm is related to mechanically triggering certain features in the service station where the as­sembly 10 resides in between printing operations, and is not relevant to the invention herein.
  • the printhead lock-in mechanism is considered unique, since it simultaneously aligns the nozzle plate in the X, Y and Z directions and aligns, wipes, and loads the contact pads of the electrical interconnect strip 16. This is accomplished with no additional bail, latch or lever arm, as seen on other ink-jet printers.
  • the alignment of the nozzle plate and the loading of the interconnect strip 16 occurs when the user rotates the cartridge 14 in the direction of the arrow 82 (FIG. 6a), about the pivot point 56r. The user does this by squeezing the cartridge thumbhold 50a and the carriage finger hold 68 between the thumb and forefinger.
  • the user Before the user can squeeze the cartridge 14 into its locked-in position, the user must be able to easily drop the cartridge into the carriage chute 20.
  • the springs 58, 62 which align the cartridge 14 do not apply any force to the cartridge until the cartridge begins to rotate into the locked-in position (shown in FIG. 6b). This leaves an unobstructed path for the user to easily drop the cartridge 14 into the pre-rota­tion position, depicted in FIG. 6a.
  • the side-­kicker spring 58 applies light force when inserting the cartridge 14.
  • the cartridge 14 rotates about the reference pads 56, specifically, point 56r. As the user rotates the cartridge 14, the alignment functions are performed before the electrical interconnect strip 16 is loaded. First, one side 36 of the cartridge 14 engages the molded-in carriage side spring 58. This spring 58 references the cartridge 14 in the X direction by push­ing the cartridge sideways until the X reference pad 56x is touching the X reference pad 60x on the car­tridge. The result is an accurate, no slop alignment of the nozzle plate in the X direction.
  • the next action to occur is the alignment in the Z direction.
  • the spring pushes the cartridge in the Z direction until the Z reference pads 56z are in contact with the Z reference pads 60z on the carriage 12.
  • the result is an accu­rate, no slop registration of both the electrical in­terconnect 16 and the nozzle plate in the Z direction.
  • the electrical inter­connect concave contact pads 48 on the cartridge con­tact 46 get wiped slightly by the convex contact dim­ples 30 on the carriage interconnect strip 16. This offers improved reliability over the dimpled intercon­ nect on prior art printers, because the oxides and contamination are wiped off the contacts 30 and 48 before the interconnect 16 is loaded.
  • the wiping action is followed by the alignment of the cartridge electrical contact pads 48 in the X di­rection. This occurs when the cartridge's outer rear heel lock tabs 84a,c engage the sides 86a,c of the heel lock slot 86 on the carriage 12.
  • the interconnect strip 16 on the carriage 12 is referenced accurately to the heel lock slot 86 by pins 27, thereby providing the required alignment of the interconnect strip to the cartridge's electrical contact pads 48.
  • the contact strip 46 is fastened, such as by glue or adhesive, to the cartridge 14 and is referenced by an assembly ma­chine.
  • the cartridge 14 is aligned accurately in the Y direction.
  • the electrical interconnect's rubber spring pad 24 on the carriage 12 must be deflected the proper distance in the Y direction in order to maintain the required contact force.
  • the rubber spring 24 pushes back against the electrical contacts 30 and 48 so that the Y refer­ence pads 56y on the cartridge contact the Y reference pads 60y on the carriage. This maintains the necessary force on the contact pads 48 located on the contact strip 46, on the rear surface 42 of the cartridge 14.
  • This also provides an accurate Y registration of the nozzle plate as well as controlling the rotational alignment of the nozzles.
  • the required contact force in the Y and Z directions is maintained by the rear snap-spring 62.
  • the rear lip 64 of the cartridge 14 deflects the rear spring-snap 62 and passes over an over-center point 62a (FIG. 6a) on the snap-spring.
  • the snap-spring 62 is designed to apply about 70% of its force in the Y direction. This is the force required to maintain the electrical interconnect 16 in the rear 42 of the cartridge 14.
  • the cartridge 14 passes the over-center point 62a on the rear snap-spring 62, the cartridge makes an audible "snap", signalling to the user that the car­tridge is in the proper locked-in position.
  • the force of the rubber interconnect spring pad 24 is adequate to hold the cartridge into its accurately aligned position under the large accelerations and shock loads the car­tridge encounters in normal printing operations.
  • the user To remove the cartridge 14 from the carriage 12, the user simply rotates the cartridge by squeezing the cartridge finger hold 50b and the carriage thumb hold 20b between the thumb and forefinger.
  • the rear ledge 64 on the carriage 14 deflects the rear snap-spring 62 until the cartridge over-centers into the unlocked position. There is an audible “snap" which tells the user that the cartridge 14 can now be lifted out of the carriage 12 for disposal.
  • the print cartridge/carriage assembly disclosed herein is suitably employed in ink-jet printers, parti­cularly thermal ink-jet printers.
