Description

  The present invention relates to a tape unit, a liquid discharge head, and a recording apparatus for closing and sealing a discharge port when being distributed in the market.

  In general, when a recording head is distributed in the market, a tape attached to a portion of the recording head where the discharge port is formed may be used in order to close and seal the discharge port. As a result, the discharge port is sealed, and it is possible to prevent the ink from leaking from the discharge port and the ink sticking around the discharge port to block the discharge port. Further, the ink is prevented from evaporating from the ejection port.

  The recording head may have irregularities formed on the surface where the discharge ports are formed. For example, a recording head may be formed by attaching a recording element substrate having ejection openings and recording elements to a support member that is a part of the casing of the recording head. In this case, the electrical wiring tape disposed on the support member and the recording element substrate may be electrically connected. For example, the inner lead exposed from the electrical wiring tape and the electrical connection portion provided on the recording element substrate may be electrically connected. And this electrical junction part may be covered with sealing materials, such as resin. In this case, by disposing the sealing material, the portion of the sealing material protrudes from the surface of the recording head where the discharge ports are formed.

  When there is unevenness on the surface of the recording head where the discharge port is formed, if the tape is applied to the entire portion of the recording head where the discharge port is formed, the periphery of the portion protruding from the surface where the discharge port is formed Thus, a gap may be generated between the tape and the recording head. Further, when the adhesive strength of the tape is weak, the gap between the tape and the recording head is enlarged, and there is a possibility that the tape will be peeled around the discharge port. When the tape is peeled around the discharge port, ink may leak from the tape, and the surface on which the discharge port is formed may be stained. In addition, inks of other colors may be mixed and affect the recorded image.

  Patent Document 1 discloses a tape that is cut into the inside of a portion that protrudes from a surface on which a discharge port is formed in a recording head. By forming slits in the tape by cutting, it is possible to suppress the formation of a gap between the tape and the surface of the recording head where the ejection openings are formed.

JP-A-6-320741

  However, the tape disclosed in Patent Document 1 requires a process of forming slits by cutting into the tape. In addition, the slit needs to be formed so as not to be located at the portion where the discharge port is formed, and accuracy is required at the formation position. As described above, in order to prevent the tape from being peeled off by forming a slit in the tape, a process for forming the slit with high accuracy is required, which complicates the manufacturing process of the recording head and increases the manufacturing cost of the recording head. There is a possibility.

  SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a tape unit, a liquid discharge head, and a recording apparatus that can be easily manufactured while preventing a gap from being generated between a tape and a recording head.

(First embodiment)
An ink jet recording head cartridge and a recording apparatus according to a first embodiment of the present invention will be described with reference to the drawings. 1 to 4 are views showing the configuration of an ink jet recording head cartridge according to an embodiment of the present invention. FIG. 1A is a perspective view of an ink jet recording head cartridge (liquid discharge head) 100 in which a recording element substrate 101 and an ink tank 103 are integrally formed. FIG. 1B is a perspective view in which the ink jet recording head cartridge 100 is disassembled into a recording element substrate 101, an electric wiring tape 102, and an ink tank 103, and the respective members are shown. As shown in FIGS. 1A and 1B, a recording element substrate 101 is attached to a main body 120 having an ink tank 103 in an ink jet recording head cartridge 100. Further, the electric wiring tape 102 is attached to a position corresponding to the recording element substrate 101 in the main body 120 to constitute the ink jet recording head cartridge 100.

  FIG. 2A is a plan view when the recording element substrate 101 is viewed from the surface. FIG. 2B is a plan view when the recording element substrate 101 is viewed from the back surface. FIG. 3 is a perspective view showing the internal configuration of the recording element substrate 101 with a part thereof broken.

  A liquid chamber 30 is defined in the recording element substrate 101 of the ink jet recording head cartridge 100. In the liquid chamber 30, ink as a liquid ejected from the ink jet recording head cartridge 100 is stored. The recording element substrate 101 is formed with an ejection port 104 that communicates with the liquid chamber 30 and ejects ink stored in the liquid chamber 30. Further, inside the liquid chamber 30, a recording element 31 is provided that imparts energy to the ink in order to discharge the ink stored in the liquid chamber 30 from the discharge port 104. An ejection port 104 for ejecting ink is formed at a position corresponding to the recording element 31 disposed in the liquid chamber 30. The ink to which thermal energy is given by driving the recording element 31 causes film boiling inside the liquid chamber 30, and thereby the ink is ejected from the ejection port 104 toward the recording medium. In addition, the recording element substrate 101 is formed with electrode pads 106 that are formed at end portions of wirings extending from the recording element 31 for transmitting electric energy to the recording element 31 and through which current is transferred.

  The recording element substrate 101 is a plate-like member made of a silicon (Si) material having a thickness of 0.625 mm. In the present embodiment, the recording element substrate 101 uses an electrothermal conversion element as the recording element 31 that generates energy for ejecting ink. By supplying power to each electrothermal conversion element, film boiling occurs in the ink stored in the liquid chamber 30. In addition, electrical wiring for transmitting current to the recording element 31 is arranged on the recording element substrate 101. Electric wiring formed of aluminum (Al) or the like is formed on the recording element substrate 101 by a film forming technique.

  Further, on the surface side of the recording element substrate 101, a flow path forming member in which a plurality of ink flow paths corresponding to these electrothermal conversion elements and a plurality of discharge ports 104 are formed is formed by a photolithography technique. In addition, an ink supply port 105 for supplying ink to the plurality of ink flow paths is formed in the recording element substrate 101 so as to penetrate the recording element substrate 101.

  FIG. 4 is a perspective view of each of the recording element substrate 101 and the electric wiring tape 102 for explaining the connection between the recording element substrate 101 and the electric wiring tape 102.

  A device hole 121 that is an opening for incorporating the recording element substrate 101 is formed in the electrical wiring tape 102. Further, inner leads 122 are formed on the side surfaces of the device hole 121 so as to protrude to the inside of the device hole 121. The inner lead 122 is formed at a position corresponding to the electrode pad 106 of the recording element substrate 101. The electrical wiring tape 102 also includes an external input terminal 123 for receiving a drive control signal from the recording apparatus main body. In the electrical wiring tape 102, the external input terminal 123 and the inner lead 122 are connected by a copper foil wiring. The electrical wiring tape 102 is configured to have flexibility. Therefore, the ink jet recording head cartridge 100 can be bent along the shape of the main body 120.

  When the recording element substrate 101 and the electric wiring tape 102 are arranged, first, the recording element substrate 101 is arranged at a predetermined position of the main body 120 in the inkjet recording head cartridge 100. Then, the electric wiring tape 102 is disposed on the recording element substrate 101 so that the inner leads 122 abut on the electrode pads 106 of the recording element substrate 101.

  FIG. 5 shows a cross-sectional view of an electrical connection portion between the recording element substrate 101 and the electric wiring tape 102. FIG. 5 is a cross-sectional view showing the end portions on both sides along the direction in which the ejection port arrays are arranged in the recording element substrate 101. In this embodiment, a TAB (Tape Automated Bonding) type tape is used as the electrical wiring tape 102. In the connection between the recording element substrate 101 and the electric wiring tape, the inner leads 122 and the electrode pads 106 of the recording element substrate 101 are heat-pressed and bonded together using a gang bonding tool. Thereby, the inner lead 122 and the electrode pad 106 are electrically connected.

  In the present embodiment, the sealing material 124 is applied to a portion where the inner lead 122 and the electrode pad 106 are electrically connected. Since the electrical connection portion between the inner lead 122 and the electrode pad 106 is covered with the sealing material 124, it is possible to suppress the liquid such as ink from adhering to the electrical connection portion between them due to recording. Can do. Thereby, it can suppress that corrosion arises in an electrical connection part by adhesion of liquids, such as ink. Further, since the connection portion between the inner lead 122 and the electrode pad 106 is covered with the sealing material 124, the connection portion can be protected from an external force. Thereby, the intensity | strength of a connection part can be improved.

  In this embodiment, in order to suppress leakage of liquid from the discharge port and evaporation of the liquid from the discharge port when the ink jet recording head cartridge 100 is distributed in the market, the portion where the discharge port 104 is formed is used. The discharge port seal tape 107 is affixed. FIGS. 6A and 6B are perspective views of the inkjet recording head cartridge 100, the discharge port seal tape 107, and the tag tape 108 (film member). In the present embodiment, the discharge port seal tape 107 and the tag tape 108 are collectively referred to as a tape unit. FIG. 6A shows a perspective view of the ink jet recording head cartridge 100 and the respective tapes in a state where the discharge port seal tape 107 is attached to the ink jet recording head cartridge 100. FIG. 6B is a perspective view of the ink jet recording head cartridge 100 and the respective tapes in a state before the discharge port seal tape 107 is attached to the ink jet recording head cartridge 100. The discharge port sealing tape 107 is formed in a flexible film shape, and has an adhesive portion to which an adhesive force is applied on one surface.

  In the recording element substrate 101, the discharge port 104 is sealed with a discharge port sealing tape 107. By sealing the ejection port 104 with the ejection port sealing tape 107, it is possible to suppress ink from leaking from the ejection port 104 and thickening of the ink around the ejection port 104. The discharge port seal tape 107 is attached to the discharge port forming surface on which the discharge port 104 is formed in the ink jet recording head cartridge 100 that discharges ink from the discharge port. Adhesive portion) 127. As a result, it is possible to prevent ink from adhering to the periphery of the ejection port and blocking the ejection port. Further, it is possible to suppress a decrease in the ink stored in the ink tank due to the evaporation of the ink from the ejection port 104.

  Further, the discharge port sealing tape 107 is attached to the surface of the tag tape 108 at a position different from the portion where the discharge port 104 is formed. As described above, the discharge port seal tape 107 has an adhesive portion (second adhesive portion) 128 to which an adhesive force is applied in order to adhere to the tag tape 108. In the present embodiment, the discharge port seal tape 107 has an adhesive force over the entire back surface in contact with the recording element substrate 101 and the inkjet recording head cartridge 100. In the present embodiment, a tag tape 108 is disposed between the ejection port seal tape 107 and the inkjet recording head cartridge 100 outside the recording element substrate 101 in the direction orthogonal to the direction in which the ejection port arrays are arranged. Yes. The tag tape 108 is formed in a flexible film shape.

  An opening 125 is formed in the tag tape 108. The tag tape 108 is disposed on the inkjet recording head cartridge 100 so that the recording element substrate 101 is disposed inside the opening 125. In the present embodiment, the tag tape 108 is disposed on the outer side of the recording element substrate 101 on the ink jet recording head cartridge 100. A tag tape 108 is disposed between the ejection port seal tape 107 and the ink jet recording head cartridge 100 at a position outside the recording element substrate 101 in the direction orthogonal to the direction in which the ejection port arrays are arranged. . That is, the tag tape 108 is disposed so as to sink into a position closer to the ink jet recording head cartridge 100 than the discharge port seal tape 107.

  As described above, the tag tape 108 is arranged so as to sink into the back side of the discharge port seal tape 107. Therefore, when the discharge port seal tape 107 is peeled off, the discharge port seal tape 107 is simply pulled by pulling the tag tape 108. Can be peeled off. Therefore, the ejection port seal tape 107 can be easily peeled from the ink jet recording head cartridge 100.

  Further, since the discharge port sealing tape 107 is attached to the discharge port forming surface at a position corresponding to the opening 125 of the tag tape 108, an adhesive portion 127 to which an adhesive force is applied is applied to the discharge port forming surface. It is done.

  In the present embodiment, the tag tape 108 does not have an adhesive force. By forming the tag tape 108 so as not to have an adhesive force, it is possible to reduce the force required when the discharge port seal tape 107 and the tag tape 108 are peeled off.

  FIG. 7 is a plan view of the inkjet recording head cartridge 100, the ejection port seal tape 107, and the tag tape 108 in a state where the ejection port seal tape 107 and the tag tape 108 are attached to the inkjet recording head cartridge 100. FIG. 8 is a cross-sectional view taken along line VIII-VIII in the discharge port seal tape 107, the tag tape 108, and the inkjet recording head cartridge 100 of FIG.

  As shown in FIG. 8, the sealing material 124 is disposed so as to cover the electrical connection portion between the inner lead 122 and the electrode pad 106, so that the portion of the sealing material 124 is disposed at the discharge port 104. It protrudes in the direction in which the liquid is ejected from the surface on which the liquid crystal is formed. That is, the connection portion between the electrode pad 106 of the recording element substrate 101 and the inner lead (wiring) 122 for supplying current from the recording apparatus main body side is covered with the sealing material 124, so that the discharge port A protruding portion 126 protruding from the forming surface is formed. Therefore, if the discharge port is sealed with a single discharge port sealing tape over the entire periphery of the recording element substrate 101, the protrusion 126 and the protrusion 126 around the protrusion 126 protruded by the sealing material 124. There may be a gap between the discharge port sealing tape 107 and the outlet port sealing tape 107.

  Therefore, in the present embodiment, the tag tape 108 is disposed outside the recording element substrate 101 so as to surround the recording element substrate 101. In addition, the discharge port seal tape 107 is formed on the portion of the recording element substrate 101 where the discharge port 104 is formed in a region inside the sealing material 124 protruding in the liquid discharge direction from the surface where the discharge port 104 is formed. Is pasted. As described above, since the ejection port seal tape 107 and the tag tape 108 are attached to the ink jet recording head cartridge 100, the tape is not attached to the portion where the protruding sealing material 124 is disposed. Since the tape does not need to be attached to the portion of the ink jet recording head cartridge 100 that protrudes in the direction in which the liquid is ejected, the occurrence of a gap between the ink jet recording head cartridge 100 and the tape can be suppressed.

  In the portion of the inkjet recording head cartridge 100 where the ejection port 104 is formed, the ejection port seal tape 107 is securely attached to the inkjet recording head cartridge 100 without providing a gap. Since no gap is formed between the discharge port sealing tape 107 and the inkjet recording head cartridge 100, the adhesive force by the discharge port sealing tape 107 is reliably exhibited. Therefore, it is possible to more reliably suppress the peeling of the discharge port seal tape 107 from the ink jet recording head cartridge 100.

  Since the ejection port seal tape 107 can be reliably prevented from peeling from the ink jet recording head cartridge 100, it is possible to prevent ink from leaking to the outside when the ink jet recording head cartridge 100 is in the market. Therefore, the periphery of the ink jet recording head cartridge 100 during distribution can be kept clean.

  Further, the discharge port seal tape 107 and the tag tape 108 are arranged so as to avoid the protruding portion 126 protruding from the discharge port forming surface where the discharge port 104 is formed in the ink jet recording head cartridge 100. In the present embodiment, a relatively large opening 125 is formed in the tag tape 108. The tag tape 108 is arranged so that the protrusion 126 passes through the opening 125 formed relatively large in the tag tape 108. In addition, the tag tape 108 is disposed so as to be disposed at a position corresponding to the relatively large opening 125 over the entire portion where the discharge port 104 is formed. At this time, since the opening 125 formed in the tag tape 108 is formed to be relatively large, high positional accuracy is not required when the tag tape 108 is arranged. Therefore, the tag tape 108 can be arranged relatively easily. Further, an adhesive force is applied to the entire surface of the discharge port seal tape 107 facing the ink jet recording head cartridge 100. The discharge port sealing tape 107 may be disposed at a position where the discharge port is sealed and adhered to the tag tape 108 after the tag tape 108 is disposed on the inkjet recording head cartridge 100. Therefore, even when the discharge port seal tape 107 is arranged, high positional accuracy is not required. Accordingly, the discharge port seal tape 107 can be arranged relatively easily. In this manner, the discharge port seal tape 107 and the tag tape 108 can be arranged relatively easily.

  In addition, since the discharge port 104 is not exposed to the outside air, it is possible to prevent the ink from being thickened around the discharge port 104. Therefore, when the ink jet recording head cartridge 100 is used with the discharge port seal tape 107 peeled off, it is possible to prevent the ink characteristics from changing, and the quality of the recorded image can be maintained high. it can. Further, it is possible to prevent the ink from being fixed due to the increase in the viscosity of the ink around the discharge port 104 and the discharge port 104 being blocked by the solidified ink. Further, it is possible to suppress the ink stored in the ink jet recording head cartridge 100 from evaporating through the ejection port. As a result, a decrease in the amount of ink inside the inkjet recording head cartridge 100 during distribution can be suppressed to a small level, and the ink inside the inkjet recording head cartridge 100 can be used efficiently.

  Further, since it is possible to suppress the formation of a gap between the ink jet recording head cartridge 100 and the discharge port seal tape 107, the adhesive force by the discharge port seal tape 107 can be efficiently exhibited. Therefore, even if the adhesive force by the discharge port seal tape 107 is weakened, the seal of the discharge port 104 can be reliably maintained. Therefore, by setting the adhesive force by the discharge port seal tape 107 to be weak, the force required when the discharge port seal tape 107 is peeled can be kept small. The portion of the ink jet recording head cartridge 100 where the discharge port is formed tends to be lower in strength than other portions because it is formed thin. Therefore, if the force required when peeling the discharge port sealing tape 107 becomes strong, the ink jet recording head cartridge 100 may be deformed due to the peeling of the discharge port sealing tape 107. In this embodiment, since the force at the time of peeling the discharge port seal tape 107 can be weakened, it is possible to prevent the ink jet recording head cartridge 100 from being deformed.

  In particular, when the surface state of the surface of the recording element substrate 101 on which the discharge port 104 is formed is hydrophilic or non-water-repellent, the force required to peel the discharge port seal tape from the recording element substrate 101 Will become bigger. Even in such a case, when the discharge port seal tape 107 and the tag tape 108 in the present embodiment are used, it is necessary to peel the discharge port seal tape 107 and the tag tape 108 from the recording element substrate 101. The force taken can be reduced. Therefore, it is possible to more reliably suppress deformation of the portion of the recording element substrate 101 where the ejection port is formed at the time of peeling.

  Next, a process for attaching the discharge port seal tape 107 and the tag tape 108 to the inkjet recording head cartridge 100 will be described. 9A, 9 </ b> B, and 9 </ b> C are cross-sectional views taken along line IX-IX in the discharge port seal tape 107, the tag tape 108, and the inkjet recording head cartridge 100 of FIG. 7. 9A, 9B, and 9C show changes in the respective states of the ink jet recording head cartridge 100, the discharge port seal tape 107, and the tag tape 108 over time.

  A discharge port seal tape 107 and a tag tape 108 are attached to the ink jet recording head cartridge 100 shown in FIG. In the present embodiment, as shown in FIG. 9B, the discharge port seal tape 107 and the tag tape 108 are bonded in advance. Then, in a state where they are bonded to each other, the discharge port seal tape 107 and the tag tape 108 are bonded to the inkjet recording head cartridge 100 as shown in FIG. 9C.

  In the present embodiment, the discharge port seal tape 107 is attached to the surface of the recording element substrate 101 where the discharge port 104 is formed, and is attached to the front surface of the tag tape 108. Here, the discharge port sealing tape 107 is not attached to the electric wiring tape 102 but is attached only to the tag tape 108.

  In addition, in the manufacturing process of the discharge port seal tape 107 and the tag tape 108, each is cut to an appropriate length from the state wound in a roll shape. In the present embodiment, when the tag tape 108 is cut, the opening 125 is also cut together to form the opening 125. In this way, the tag tape 108 can be formed in a desired shape without increasing the number of manufacturing steps.

  FIG. 10 is a perspective view of an ink jet recording apparatus 1000 on which the ink jet recording head cartridge 100 shown in FIG. 1 is mounted. In the ink jet recording apparatus 1000 of this embodiment, recording is performed by mounting the ink jet recording head cartridge 100 shown in FIG. The carriage 211 is guided so as to be movable in the main scanning direction indicated by an arrow A along the guide shaft 206. The guide shaft 206 is disposed so as to extend along the width direction of the recording medium. The ink jet recording head cartridge 100 mounted on the carriage 211 performs recording while scanning in the direction intersecting the transport direction in which the recording medium is transported. As described above, the ink jet recording apparatus 1000 is a so-called serial scan type ink jet recording apparatus that records an image with the movement of the ink jet recording head cartridge 100 in the main scanning direction and the conveyance of the recording medium in the sub scanning direction. . A plurality of inkjet recording head cartridges 100 corresponding to the types of ink that can be ejected from the inkjet recording apparatus are mounted on the carriage 211, and the carriage 211 functions as a liquid ejection head mounting unit that can mount a liquid ejection head. To do. After the recording medium is stacked on the paper feeding unit 215, the recording medium is transported in the sub-scanning direction indicated by arrow B by the transport roller.

  The ink jet recording apparatus 1000 repeats a recording operation for ejecting ink while moving the ink jet recording head cartridge 100 in the main scanning direction and a transport operation for transporting the recording medium in the sub scanning direction. Record images sequentially. When ink is ejected, a current is supplied from the inner lead 122 to the electrode pad 106 at a predetermined timing according to the recording data. When a current is supplied to the electrode pad 106, a current is supplied from the electrode pad 106 to the recording element 31 through the wiring. Thus, the recording element 31 is driven by supplying the current to the recording element 31. The recording element 31 is driven to cause film boiling of the ink to which thermal energy is applied inside the liquid chamber 30. As a result, ink is ejected from the ejection port 104 toward the recording medium, and recording is performed on the recording medium.

  In the above embodiment, an ink jet recording head cartridge in which the recording head and the ink tank are integrally formed will be described. However, the present invention is not limited to this, and a system in which the recording head and the ink tank can be attached and detached. May be adopted.

  Moreover, in the said embodiment, although the tag tape 108 is formed so that it may not have adhesive force, this invention is not limited to this. The tag tape 108 may be formed to have an adhesive force, and the tag tape 108 may be attached to the electric wiring tape 102. When the tag tape 108 has an adhesive force, the tag tape 108 may have an adhesive force over the entire back surface of the tag tape 108 that contacts the inkjet recording head cartridge 100.

  In the above embodiment, the discharge port sealing tape 107 for sealing the discharge port and the tag tape 108 are configured as separate members. Therefore, when the tag tape 108 has an adhesive force, the adhesive force can be easily changed between the discharge port seal tape 107 and the tag tape 108. Therefore, it is possible to set the adhesive force according to each application to each of the discharge port seal tape 107 and the tag tape 108.

  Moreover, in the said embodiment, the discharge outlet sealing tape 107 has a uniform adhesive force over the whole back surface. However, the present invention is not limited to this, and the discharge port sealing tape 107 may have an adhesive force only in a necessary portion. For example, the discharge port seal tape 107 may have an adhesive force only on the outer side in the direction orthogonal to the position corresponding to the periphery of the discharge port 104 and the direction in which the discharge port array is arranged. When the tag tape 108 has an adhesive force, the tag tape 108 may also have an adhesive force only at a position corresponding to the periphery of the recording element substrate 101.

(Second Embodiment)
Next, a second embodiment of the present invention will be described.
